", "My motives for writing the present essay, for pursuing the philosophy of perception through its history, derive from a number of sources. ", "Let me take this opportunity to describe some of them. ", "For a number of years, over a series of papers (Kalderon, 2007, 2008, 2011b,a,c) that followed on from an earlier collaboration (Hilbert and Kalderon, 2000), I have defended an antimodern conception of color and color perception. ", "According to that conception, colors are mind-independent qualities of material surfaces, transparent volumes, and radiant light sources, and color perception is the presentation of particular instances of these qualities in the visual awareness afforded by the subject's perceptual experience. ", "This is how, I argue, our color experience presents itself as being, and I undertook to defend this conception from challenges that arise from the problem of conflicting appearances-what Hume (1748) regarded as the \"slightest bit of philosophy\" required to reject any such conception of color and color perception. ", "This conception is an antimodern conception of color in that, in the face of a consensus that persisted for four centuries-remarkable indeed in philosophy-colors are not conceived to be secondary qualities. ", "Indeed, they are on a par with shape. ", "And this conception is an antimodern conception of color perception in that color perception is not merely a mental reaction, a conscious modification of the perceiving subject, but the presentation of mind-independent qualities of spatiotemporal particulars located at a distance from the perceiving subject. ", "Defending an antimodern conception of color and color perception prompted me to investigate premodern conceptions of color and color perception. ", "I had, at any rate, been drawing on ancient sources in thinking about the problem of conflicting appearances as it arises in its contemporary guise. ", "However, just because the conception defended was antimodern, did not make it premodern. ", "I turned to premodern sources for at least two reasons. ", "First, to further loosen the grip of the modern conception of color and color perception. ", "Though thoroughly convinced of its error, it had been my experience v vi CONTENTS that the effects of this dominant paradigm lingered in my thinking, and I engaged with premodern thinkers to counteract this.

", "Chapter 1 Empedocles 1.1 Dialectic The present essay concerns Aristotle's dialectical engagement with Empedocles about the nature of color perception. ", "It is only by paying careful attention to such engagement can we arrive at a proper understanding of Aristotle's notorious definition of perception as the assimilation of the sensible form without the matter of the perceived object. ", "I shall argue that Aristotle's definition of perception is a resolution of a puzzle or aporia about the nature of perception that animated Empedocles' theory of vision. ", "The puzzle concerns the sensory presentation of remote sensible objects as when we see the brilliant white of the distant sun. ", "This chapter details the original form of Empedoclean puzzlement and shows how Empedocles' theory of vision is an attempt to resolve such puzzlement, though an attempt that, as we shall see in chapter 2, Aristotle rejects as unworkable. ", "But before we discuss the puzzle which animates Empedocles' theory of color vision, it will be useful to briefly describe Aristotle's dialectical engagement with the endoxa more generally. ", "Dialectical argument is a mode of reasoning that uses the endoxa as premises. ", "The endoxa are the reputable opinions of one's predecessors. ", "The reputable opinions: ... are accepted by everyone or by the majority or by the wise-i.e. by all, or by the majority, or by the most notable and reputable of them. (", "Aristotle, Topica i 1 101a35–37; Pickard-Cambridge in Barnes 1984b, 2-3) The opinions of the many and the wise are the source of both truth and error. ", "Dialectical argument contrasts, in this way, with geometrical demonstration. ", "Geometrical demonstration begins, not with the opinions of predecessors which may be a source of truth or error, but with premises that are primitive truths. ", "That the relevant opinions are widespread or are offered by the wise at least 1 2 CHAPTER 1. ", "EMPEDOCLES makes it likely that some element of truth is to be found among them. ", "This is important insofar as dialectical argument is an alethic activity: For the study of the philosophical sciences it is useful, because the ability to puzzle on both sides of a subject will make us detect more easily the truth and error about the several points that arise. (", "Aristotle, Topica i 2 101a35–37; Pickard-Cambridge in Barnes 1984b, 3–4) Dialectical argument thus serves a dual purpose. ", "On the one hand, it makes it easier to discern what truth there is in the respected opinions of the predecessors. ", "On the other hand, it makes it easier to eschew the errors of these same predecessors. ", "Within the context of philosophical inquiry, then, dialectical argument is a means of determining the truth and avoiding error. ", "If that is right, then this leaves open the possibility that at least some of what Empedocles has to say is true, at least on some understanding of what was said-though not necessarily Empedocles'. ", "Thus, for example, in chapter 7, we shall see how Aristotle accepts Empedocles' analogy between the eye in seeing and a lantern dk 31b84 but only on a novel understanding of that analogy. ", "And in chapter 9, we shall see that while Aristotle accepts the Empedoclean claim that perception is a mode of assimilation, he has a very different understanding of what assimilation involves in perceptual experience. ", "Dialectical argument proceeds by first collecting and organizing the respected opinions of one's predecessors and then by developing certain puzzles or aporiai concerning the opinions that have been collected. ", "These difficulties or puzzles either arise directly from the opinions of the many or the wise-when they conflict, say-or is the result of the development of these opinion with material external to the endoxa. ", "Determining, as best one can, what the appropriate resolution of such difficulties would be, is a means of avoiding the errors in the endoxa while importantly preserving what insights there are as one advances one's judgment. ", "The conclusion of a dialectical argument, if successful, is a genuine advance in judgement. ", "It is an advance not only that by means of it one may come to know something about which one was previously ignorant, but it is also an advance in the sense that dialectical argument is ampliative in the way that geometrical demonstration is not. ", "The truth known on the basis of dialectical argument is not already contained among what the truths there are in the reputable opinions of one's predecessors. ", "A sense of how dialectical argument may advance judgment emerges in Aristotle's discussion, in the Metaphysica, of the relevance of the dialectical argument for philosophical inquiry: For those who wish to get clear of difficulties it is advantageous to state the difficulties well; for the subsequent free play of thought implies the solution of the previous difficulties, and it is not possible to untie a knot which one does not know. ", "But the difficulty of our thinking points to 1.1. ", "DIALECTIC 3 a knot in the object; for in so far as our thought is in difficulties, it is in like case with those who are tied up; for in either case it is impossible to go forward. ", "Therefore one should have surveyed all the difficulties beforehand, both for the reasons we have stated and because people who inquire without first stating the difficulties are like those who do not know where they have to go; besides, a man does not otherwise know even whether he has found what he is looking for or not; for the end is not clear to such a man, while to him who has first discussed the difficulties it is clear. ", "Further, he who has heard all the contending arguments, as if they were the parties to a case, must be in a better position for judging. (", "Aristotle, Metaphysica b 1 995a27–995b4; Ross in Barnes 1984a, 28) Identifying and critically assessing such puzzles forces one to examine assumptions that may never have been questioned and yet may prove to be false. ", "Moreover, unexamined false assumptions can hinder further investigation. ", "In these ways, dialectical argument is a means of avoiding error. ", "In identifying and assessing such puzzles one knows better how to conduct one's inquiry. ", "Moreover, in the course of dialectical reasoning one gains experience with the object of inquiry thus putting one in a better position to judge of its true nature. ", "In these ways, dialectical argument is a means for determining the truth. ", "Thus in order be free from the distorting influence of false assumption as well as to be in a better position for judging the true nature of perception, Aristotle must first consider the difficulties that arise in the endoxa concerning the nature of perception. ", "In De Anima, Book i is devoted to an elaborate and extended discussion of these difficulties as they arise with respect to the motion of the soul and whether the soul is best conceived as a kind of harmony. ", "In contrast to the characterization of the endoxa given in Topica, however, he restricts himself to the opinions of the wise as opposed to the many. ", "Empedocles is prominent among the wise whose opinions are considered in Book i. However, it would be a mistake to see Aristotle's dialectical engagement with the endoxa as confined to Book i. For example, De Anima ii 5 begins by discussing an aporia about alteration as it is understood by the endoxa, albeit one that echoes important elements of the Book i discussion of the motion of the soul. ", "Moreover, Aristotle's dialectical engagement with Empedocles is not itself confined to Book i, nor is his engagement with the reputable opinions of other predecessors, Plato prominent among them. ", "The puzzle with which we will be primarily concerned, a puzzle about the visual presentation of the colors of remote external particulars, is a puzzle to be found in the respected opinion of Empedocles. ", "So it is a puzzle that arises strictly within the endoxa, requiring no further development from without. ", "Moreover, the endoxa, here, seems restricted to the wise. ", "However, this may, in the end, be misleading. ", "4 CHAPTER 1. ", "EMPEDOCLES Empedocles is attempting to reconcile certain aspects of the manifest image of nature with Parmenidean insights that may seem to conflict with it, and did so seem to Parmenides. ", "Empedocles' theory of vision is part of this larger project. ", "Empedoclean puzzlement arises from Empedocles' description of common phenomenological aspects of our experience of nature. ", "Insofar as there are insights to be preserved in the respected opinion of Empedocles, the source of the puzzle described by Empedocles may lie with the way our sensory experience presents itself to be. ", "But insofar as the source of the puzzlement lies, in part, with Empedocles description of sensory experience, then the puzzle arises from the way the wise articulates the phenomenology of the many. ", "In any case, the focus is on the object of dialectical inquiry, in the present instance, the visual presentation of the colors of remote external particulars. ", "1.2 The Answer in the Style of Gorgias In the Meno Socrates attributes to Empedocles a conception of perception as a mode of assimilation of material effluences: meno: And how do you define color? ...

", "meno: Yes. ", "socrates: From these notions, then, 'grasp what I would tell,' as Pindar says. ", "Color is an effluence from shapes commensurate with sight and perceptible to it. (", "Plato, Meno 76a−d; Guthrie in Hamilton and Cairns 1989, 359) The main elements of the account are relatively clear. ", "Objects emit material effluences. ", "Effluences are fine bodies that are kind differentiated in terms of mag1.2. ", "THE ANSWER IN THE STYLE OF GORGIAS 5 nitude. ", "There are passages in which and through which material effluences may flow. ", "Whether a material effluence may enter a passage depends upon its magnitude. ", "The magnitudes of some kinds of material effluences are too great or too small for them to flow through a given passage. ", "The magnitude of a material effluence must be commensurate with the magnitude of a passage in order for the effluence to fit the passage and so pass through it. ", "Such passages exist in the membrane of the eye, thus allowing the eye to assimilate only a certain kind of material effluence, that is, the kind whose magnitude permits entry in ocular passages. ", "Thus we arrive at the answer in the style of Gorgias. ", "That answer has three components. ", "It specifies a kind of thing and two conditions that must be satisfied for a thing of that kind to be color. ", "Color is (1) a kind of material effluence that is (2) commensurate with sight and (3) perceptible. ", "First, color is a kind of material effluence, a chromatic effluence, say. ", "Since material effluences are kind differentiated by magnitude, chromatic effluences have a distinctive magnitude. ", "Second, chromatic effluences are commensurate with sight insofar as their distinctive magnitude permits entry in the passages of the membrane of the eye, the organ of sight. ", "Notice, however, the assimilation of chromatic effluences by the organ of sight is not, by itself, the sensing of colors, otherwise the final condition would be redundant. ", "The assimilation of chromatic effluence is at best a material precondition for their sensing. ", "The thought seems to be this: In order for the chromatic effluences to be the object of sense, they first must be assimilated by the organ of sensation. ", "It is only by assimilating chromatic effluences that they are presented to sight and are thereby seen. ", "Socrates claims that the answer in the style of Gorgias may be generalized to the other sensory objects such as sound and smell (Meno 76d), a claim echoed by Theophrastus' account of Empedocles (De Sensibus vii). ", "If that is right, then Empedocles, at least as presented by Socrates, is in the grip of a general conception of sensory awareness for which ingestion provides the model. ", "Compare-in eating an olive, the matter of the olive is taken in and presented to the organ of taste and thereby tasted. ", "On the ingestion model, to be perceptible is to be palpable to sense. ", "The underlying thought is that in order for something to be the object of sense, it must be presented to the sense organ. ", "On the ingestion model, it is a general feature that taste shares with paradigmatic cases of touch that is operative-the object of sensation must be in contact with the sense organ for it to be sensed. ", "I say \"paradigmatic\" cases of touch since it is arguable, at least, that one can feel something that one is not in direct contact with. ", "Thus one might feel the wooden frame of a Victorian rocking horse through the padding (the issue is further explored in chapter 2.2). ", "Theophrastus' commentary supports the suggestion that, according to Empedocles, an object must be in contact with the sense organ for it to be sensed (on the reliability of Theophrastus as a doxogapher see Kahn 1994; Bal6 CHAPTER 1. ", "EMPEDOCLES tussen 2000). ", "Following Aristotle's doxographic taxonomy (De Anima i 2 404b12– 15; cf Metaphysica b 4 1000b5–8), Theophrastus counts Empedocles as a likeness theorist-as explaining perception in terms of the similarity of the elements that compose the object of sense and the sense organ. ", "That attribution is controversial (see Kamtekar 2009). ", "However, in De Sensibus xv, Theophrastus concedes that Empedocles remains silent on the compositional similarity of the material effluence and the sense organ that assimilates it, emphasizing instead the role of contact in perception (Kamtekar, 2009; Sedley, 1992): For he attributes our recognition of things to two factors-namely, to likeness and to contact; and so he uses the expression \"to fit\". ", "Accordingly if the smaller touched the larger ones, there would be perception. ", "And likeness also, speaking generally, is out of the question, at least according to him, and commensurateness alone suffices. ", "For he says that substances fail to perceive one another because their passages are not commensurate. ", "But whether the effluence is like or unlike he leaves quite undetermined. (", "Theophrastus, De Sensibus xv; Stratton 1917, 79) To be perceptible is to be palpable to sense. ", "If one began with that thought, a puzzle would naturally arise about vision, for vision seems to present the colors of distant objects. ", "Color perception seems to involve the presentation of color qualities inhering in bounded particulars located at a distance from the perceiver. ", "But how can one assimilate what remains inherent in a bounded particular remote from one? ", "The puzzlement arise from the apparent tension between two claims: (1) The objects of color perception are qualities of external particulars located at a distance from the perceiver. (", "2) The Empedoclean principle: To be perceptible is to be palpable to sense-in order for something to be the object of perception it must be in contact with the relevant sense organ. ", "I conjecture that, whatever independent reasons Empedocles may have had for believing in material effluences, it is precisely this puzzlement that effluences are meant to address in his theory of vision. ", "The basic idea is simple enough, at least in broad outline. ", "Distant objects may be sensed by sensing the material effluences they emit. ", "If the color of an object is the material effluence that it emits, then the color of a remote object can be assimilated and so be palpable to sight. ", "In this way, we can see the color of a bounded particular remote from us consistent with the constraints imposed by the ingestion model. ", "One may wonder whether the theory of effluences is wholly adequate to this task, at least without supplementation. ", "Can we really see remote colored particulars on Empedocles's theory of vision, or are these occluded from view by the 1.3. ", "EMPEDOCLES' THEORY OF VISION 7 chromatic effluences they emit? ", "Thus a Berkelean worry naturally arises about the immediate objects of sensation, the assimilated effluences, screening off the external objects that emit them. ", "Moreover, it is not just colored objects that appear at a distance, but the colors themselves seem somehow confined to the remote bounded region in which they inhere. ", "This aspect of color phenomenology is unexplained and perhaps inexplicable if sensed color is an effluence palpable to the perceptive part of the soul located within. ", "Finally, there is a worry that in identifying colors with kinds of material effluences, Empedocles conflates ontological categories. ", "Effluences are material bodies, but colors are not bodies, not even very fine bodies. ", "Colors are, instead, qualities that could not exist apart from the bodies in which they inhere, at least according to the Categoriae. (", "Not only does Aristotle have the resources to press this objection, but, as we shall see, when the same issue arises with respect to light, he adopts a parallel position, that light is not a body but a state, chapter 3.2.) ", "Fortunately, it is the puzzle that arises from Empedocles' conception of sensory presentation, and not his resolution of it, that is our focus here. ", "1.3 Empedocles' Theory of Vision Empedocles' own theory of color vision is more elaborate than the answer in the style of Gorgias. ", "Despite being more elaborate, the ingestion model remains at the core of that theory. ", "One element missing from the account that Socrates offers to Meno is the eye's emission of fiery effluences. ", "That effluences may flow out of passages as well as in is consistent with, if not indeed suggested by, Socrates' general description of passages in which and through which effluences may flow. ", "This is worth considering, since it can seem to offer an explanation that conflicts with the explanation of color vision in terms of the assimilation of material effluences. ", "And while Aristotle notes the apparent tension, Theophrastus provides the basis for understanding the role the emission of fiery effluences plays in the assimilation of chromatic effluences. ", "Aristotle (De Sensu ii 437b27–438a3) cites the following passage from Empedocles: As when someone planning a journey prepared a lamp, the gleam of blazing fire through the wintry night, and fastened linen screens against all kinds of breezes, which scatter the wind of the blowing breezes But the light leapt outwards, as much of it as was finer, and shone with its tireless beams across the threshold; in this way [Aphrodite] gave birth to the rounded pupil, primeval fire crowded in the membranes and in the fine linens. ", "8 CHAPTER 1. ", "EMPEDOCLES And they covered over the depths of the circumfluent water and sent forth fire, as much of it as was finer. (", "Empedocles, dk 31b84; Inwood 2001, 103 259) On this basis, Aristotle maintains that, like Plato in the Timaeus, Empedocles explains vision in terms of the emission of fire. ", "But then he remarks \"Sometimes he accounts for vision thus, but at other times he explains it by emanations from the visible objects\" (De Sensu ii 438a3–4; Beare in Barnes 1984b, 5). ", "So, at the very least, Aristotle thinks that Empedocles is potentially offering distinct explanations of color vision-one in terms of the eye's emission of a fiery effluence and the other in terms of the eye's assimilation of chromatic effluences. ", "But if Empedocles explains vision by the assimilation of chromatic effluence, why does he also need the emission of a fiery effluence? ", "Is Empedocles really offering conflicting explanations of vision? ", "In the passage cited by Aristotle, Empedocles describes the anatomy of the eye by analogy with an artifact, a screened lamp, constructed from linen or shaved horn, say. ", "While it is controversial how to understand the composition of the screen (see Wright 1981, 240–241), interpreting the screen as composed of linen has the advantage of more closely echoing the fine membrane that Aphrodite weaves. ", "Just as there is fire in the interior of a screened lamp, there is a primeval fire in the interior of the eye, or perhaps the pupil. ", "And just as the screen of linen or shaved horn surrounds the fire in the lamp's interior, there is a membrane that surrounds the fire in the eye's interior. ", "Moreover, the membrane plays a similar role to the screen. ", "Just as the screen protects the interior fire from the wind which would extinguish it, the primeval fire is protected from the depth of the surrounding water by the membrane of the eye.

(", "Bergson, 1907, 168) But how can retinal touch perceive distant objects without first perceiving the objects between? ", "Indeed, how can retinal touch perceive distant objects at all? ", "Bergson never explains how this miracle is brought off. ", "Less than half a century later, Broad reports a similar puzzlement: It is a natural, if paradoxical, way of speaking to say that seeing seems to 'bring us into contact with remote objects' and to reveal their shapes and colors. (", "Broad, 1952, 33) This natural if paradoxical way of speaking is ubiquitous among contemporary philosophers of perception, but the miraculous character of the phenomenon goes largely unremarked. ", "A recent notable exception is Valberg (1992). ", "Valberg addresses a puzzle that arises about the sensory presentation of distal objects if sensory experience is located where the perceiver is: 1.4. ", "EMPEDOCLEAN PUZZLEMENT 13 How could the man 'out there', at a distance from my head, be present in my experience, if my experience is something which is occurring 'back up here', inside my head?

", "The puzzlement consists in an inability to understand how to coherently combine the distal character of the objects of sight with a conception of sensory awareness as a mode of assimilation. ", "It would be premature to dismiss that conception, even in its original Empedoclean form, as primitive physiology of vision. ", "Indeed, Aristotle retains the conception of perception as a mode of assimilation even as he transforms it in rejecting Empedocles' theory of effluences. ", "Aristotle retains that conception presumably because he felt that there was an insight that should be preserved in Empedocles' opinion. ", "Aristotle is not alone in thinking that there is an insight to be preserved in conceiving of sensory awareness as a mode of assimilation. ", "Thus Broad (1952) speaks of the presentation of the objects of visual awareness as a mode of prehension. \"", "Prehension\" belongs to a primordial family of broadly tactile metaphors for sensory awareness that includes \"grasping\", and \"apprehending\". ", "What unites these metaphors is that they are all a mode of assimilation, and \"ingestion\" is a natural variant (see Johnston, 2006; Price, 1932, 7). ", "For what it is worth, assimilation as a metaphor for perception is inscribed in the history of the English language. ", "The word \"perception\" derives from the Latin perceptio meaning to take in, or assimilate (Burnyeat, 1979, 102)-evidence, at least, for the persistence of an inclination. ", "It is natural, then, to think of seeing as taking in the external scene before one. ", "But then the question arises: How can one take in what remains external? ", "And if one can, what could taking in mean, here, such that one could? ", "Empedoclean puzzlement, in its most general form, consists in the persistence of this latter question. ", "It is worth wondering about the prevalence of tactile metaphors for visual awareness. ", "There is an Aristotelian explanation, I think. ", "The explanation is Aristotelian, not in the sense that Aristotle gives the explanation or even entertains it. ", "Rather, it is Aristotelian in that it draws on resources available in Aristotle's thought. ", "According to Aristotle, taste and touch are primitive forms of sensation common to all animals (though animals can and do differ in their possession of other sensory capacities). ", "Whereas the objects of the distal senses are for the animal's well-being, the objects of touch concern the animal's very existence (De Anima iii 13 433b31–434a10). ", "What we touch may put us in mortal danger or provide us with vital sustenance. ", "Touch is primitively compelling because of its existential character. ", "Suppose then, at least in human beings, the primitive character of touch is manifest in our emotional responses to things. ", "Often when we see something we are 14 CHAPTER 1.

", "Thus we must endeavor to teach children to keep their hands to themselves, and even in maturity, polite notices are required to remind adults to not touch the display cabinet. ", "Grasping is sufficiently phenomenologically compelling that it becomes, in the cosmology of the Giants, a touchstone for reality. ", "Thus in the Sophist the Eleatic Visitor reports: One party is trying to drag everything down to earth out of heaven and the unseen, literally grasping rocks and trees in their hands, for they lay hold upon every stock and stone and strenuously affirm that real existence belongs only to that which can be handled and offers resistance to the touch. (", "Plato, Sophist 246a; Cornford in Hamilton and Cairns 1989, 990) If real existence belongs only to that which can be handled and offers resistance to touch, then only the palpable is real. ", "Sensory perception is a mode of awareness. ", "Awareness must be an awareness of what is real if it is to be awareness at all. ", "It follows that the objects of perception must themselves be palpable. ", "It is a further claim, however, that not only are the objects of perception palpable, but they are palpable, as well, to the organ of sense, in the way that Empedocles requires. ", "Sensory perception presents itself as a mode of awareness of particulars arrayed in the natural environment. ", "And the Empedoclean thought would be that perception could only be as it presents itself to be if its objects were palpable to the organ of sense. ", "But even if real existence belongs only to that which can be handled and offers resistance to touch, it does not follow that the perceptible must be palpable to sense. ", "Grasping may manifestly be a mode of sensing, but it does not follow that it is the only mode, or that all modes of sensory presentation must be understood on its model. ", "The Giants' metaphysical principle, only the palpable is real, may not entail the Empedoclean principle, to be perceptible is to be palpable to sense, nevertheless the appeal of these distinct principles flow from a common source, the vivid and primitively compelling phenomenology of an external particular's resistance to touch. ", "If the presence of things is most keenly felt when grasped, if in the resistance to touch their presence is manifest in a primitively compelling manner, then it would be no surprise that we reach for tactile metaphors in characterizing sensory presentation, even as it figures in nontactile modes of sensory awareness such as vision. ", "If the Aristotelian explanation is correct, then the tactile metaphors are emphasizing the presentation of the objects of sensory awareness. ", "It is because objects grasped are presented to us in a primitively compelling manner, that grasping can serve as a paradigm of sensory presentation. ", "On the Aristotelian explanation, the palpable is 1.5. ", "DEFINITION 15 real-touch is a genuine mode of sensory awareness. ", "But neither the Giants' principle nor Empedocles' follows. ", "The palpable may be real, but it is not the case that only the palpable is real. ", "Aristotle accepts the Eleatic Visitor's observation that virtues and capacities are real if not palpable. ", "Nor is it the case that only by being palpable to the organ of sense is an object perceptible. ", "Indeed, Aristotle will argue that an object's contact with a sense organ precludes sensation. ", "If the Aristotelian explanation is correct, then Empedoclean puzzlement, in its original form, is the result of overgeneralizing from a paradigm case. ", "To be sure, vision involves the presentation of colors inhering in bounded particulars remote from the perceiver. ", "But if the presentation of color in sensory consciousness is too closely modeled on a capacity to grasp or take in something material, then a puzzle arises that only the theory of effluences may resolve. ", "If indeed it does. ", "I have already mentioned three reservations: (1) the Berkelean worry about the immediate objects of perception, the assimilated effluences, screening off the distal objects that emit them; (2) that perceived color itself appears to inhere in the remote bounded region of the external particular; and (3) that colors belong to a different ontological category from material bodies. ", "As we shall see in the next chapter, Aristotle has his own criticisms to make of Empedocles' theory of color vision. ", "Far from being a necessary condition on perception, contact with the sense organ precludes perception. ", "Placing a colored particular on the eye blinds the perceiver to the particular and its color (De Anima ii 7 419a13–14). ", "If Aristotle's criticism proves cogent, then Empedoclean puzzlement, in its original form, not only involves an overgeneralization from a paradigm case but a misconception of it as well. ", "If to be palpable is to be imperceptible, then not even touch works by the object of sense being in contact with the sense organ. ", "Grasping may be a paradigm case of sensory presentation, but not because it involves an object being in contact with a sense organ. ", "Rather, it is a paradigm case because objects grasped are presented to us in a primitively compelling manner. ", "But even if we resist the temptation to which Empedocles apparently succumbed, to overgeneralize, in this way, from a misconception of a paradigm case, there remains the question: What could the sensory presentation of qualities of remote external particulars be, if not simply their being palpable to sense? ", "1.5 Definition In De Anima ii 12 424a18–23, ii 5 418a3–6 Aristotle defines perception as a mode of assimilation of the sensible form without the matter of an external particular. ", "This is an instance of Aristotle's dialectical refinement of the endoxa (on Aristotle's dialectic in De Anima see Witt, 1995). ", "While denying that sight involves the assimilation of material effluences, Aristotle retains Empedocles' conception of sensory 16 CHAPTER 1. ", "EMPEDOCLES awareness as a mode of assimilation, it is just that we assimilate form without matter. ", "Indeed, this pattern of dialectical refinement continues in the very next line where Aristotle uses Plato's metaphor of wax receiving an impression, not to characterize judgment as Plato does in the Theaetetus 194c–195a, but to characterize the assimilation of sensible form in perception. ", "Given this pattern of dialectical refinement, we can be confident that Aristotle was engaging with Empedocles' thought in his definition of perception. ", "And while it remains controversial how to understand the assimilation of sensible form, I believe progress can be made by interpreting Aristotle's definition of perception as addressing Empedocles' puzzlement about how remote objects can be present in sensory consciousness. ", "Recall Empedoclean puzzlement begins with the natural thought that in seeing one takes in the external scene. ", "The question then arises: How can we take in what remains external? ", "And if one can, what could taking in mean such that one could? ", "The proposal is to interpret Aristotle's definition of perception as an answer to this latter question-a remote object can be present in sensory consciousness by assimilating its sensible form while leaving its matter in place. ", "Understanding how Aristotle's definition of perception so much as could be a resolution of Empedoclean puzzlement imposes a substantive constraint on interpreting that definition, for so interpreted, it is making an important claim about the metaphysics of sensory presentation. ", "Aristotle's definition of perception is a dialectical refinement of the endoxa insofar as it seeks to preserve an Empedoclean insight while resolving a puzzle about how remote objects can be present to sensory consciousness. ", "Empedocles' puzzlement about the nature of sensory presentation persists to this day, though now in the guise of discussions of presence in absence. ", "Perhaps there are insights of Aristotle's own that ought to be preserved when confronting Empedoclean puzzlement as it arises in its modern guise. ", "If there are, then a conception of sensory presentation that preserved Aristotle's insight into the proper resolution of Empedoclean puzzlement would itself be a dialectical refinement of the respected opinion of Aristotle. ", "What these insights might be and whether any conception of sensory presentation answers this description remains to be determined. ", "Chapter 2 Perception at a Distance In its original form, Empedoclean puzzlement about the sensory presentation of remote objects consists in the apparent tension between two claims: (1) The objects of color perception are qualities of external particulars located at a distance from the perceiver.

", "Aristotle further holds that \"All relatives are spoken of in relation to correlatives that reciprocate\" (Categoriae vii 6b28; Ackrill in Barnes 1984b, 11) provided that they are properly given (Categoriae vii 7a22–23). ", "Thus the larger is larger than the smaller and the smaller is smaller than the larger. ", "Aristotle explains the constraint that correlatives that reciprocate be properly given as follows: For example, if a wing is given as of a bird, bird of a wing does not reciprocate; for it has not been given properly in the first place as wing of a bird. ", "For it is not as being a bird that a wing is said to be of it, but as being a winged, since many things that are not birds have wings. ", "Thus if it given properly there is reciprocation; for example, a wing is wing of a winged and a winged is winged with a wing. (", "Aristotle, Categoriae vii 6b38–7a5; Ackrill in Barnes 1984b, 12) A bird is a winged, but the relative that reciprocates is only properly given in terms of the relevant underlying relation. ", "To be a wing is to be related in a certain way to something as its wings, that is to say, to a winged-something considered only in so far as it bears the winged relation to a wing. ", "A bird does not reciprocate a wing since there are things with wings that are not birds. ", "Being a bird does not wholly consists in having wings as parts and so is not a correlative. ", "According to Aristotle, sense and sensibilia, perception and the perceptible, are correlatives, as are knowledge and the knowable. ", "Perceptual and epistemic correlatives differ from other correlatives in two important ways, however. ", "First, Aristotle observes that: \"knowledge is called knowledge of what is knowable, and what is knowable knowable by knowledge; perception perception of the perceptible, and the perceptible perceptible by perception\" (Categoriae vii 6b28–36; Ackrill in Barnes 1984b, 11–12). ", "Knowledge and perception are alike in that each takes an object, and they differ in this way from other correlatives, such as the larger and the smaller, the wing and the winged. ", "Second, Aristotle argues that the perceptible must be prior to perception: The perceptible seems to be prior to perception. ", "For the destruction of the perceptible carries perception to destruction, but perception does not carry the perceptible to destruction. ", "For perceptions are to do with 22 CHAPTER 2. ", "PERCEPTION AT A DISTANCE body and in body, and if the perceptible is destroyed, body too is destroyed (since body is itself a perceptible), and if there is not body, perception too is destroyed; hence the perceptible carries perception to destruction. ", "But perception does not carry the perceptible. ", "For if animal is destroyed perception is destroyed, but there will be something perceptible, such as body, hot, sweet bitter, and all the other perceptibles. ", "Moreover, perception comes into existence at the same time as what is capable of perceiving-an animal and perception come into existence at the same time-but the perceptible exists before perception exists; fire and water and so on, of which an animal is itself made up, exist even before there exists an animal at all, or perception. ", "Hence the perceptible would seem to be prior to perception. (", "Aristotle, Categoriae vii 7b35–8a13; Ackrill in Barnes 1984b, 13–14) Perception and the perceptible, sense and sensibilia, may be correlatives, but that is consistent with the following asymmetry-the perceptible can exist prior to perception and so does not depend upon perception the way perception depends upon its object. ", "Aristotle gives two arguments: (1) that perception existentially depends upon the perceptible, and (2) that the perceptible does not existentially depend upon perception. ", "Taken together (1) and (2) entail that the perceptible is existentially prior to perception. ", "The argument for (1) takes an interesting and perhaps unexpected form. ", "One might have expected Aristotle to argue that since perception essentially takes an object there must be something that the perception, or perhaps the perceiver, is perceptually related to. ", "Thus if the perceptible, understood as potential relata of the perceptual relation, does not exist, neither does any perception of them. ", "But that is not, in fact, how Aristotle argues. ", "Aristotle emphasizes, instead, that perceptions are the exercises of perceptual capacities possessed by certain natural bodies, namely, animals. ", "These bodies-the bodies that possess perceptual capacities, capacities whose proper exercise consists in the presentation of their primary objects, color for sight, sound for hearing-are themselves perceptible. ", "So if nothing perceptible exists, nothing in fact has the capacity to perceive. ", "And if nothing has the capacity to perceive, there are no perceptions. ", "The argument for (2) is more straightforward but retains the focus on certain natural bodies, animals, understood as the possessor's of perceptual capacities. ", "Suppose there are no animals. ", "Then nothing possesses the capacity to perceive. ", "And if nothing has the capacity to perceive, there are no perceptions. ", "Nevertheless, consistent with the absence of perceivers, the perceptible would persist. ", "An Extinction Level Event may destroy all animal life, and, hence, all perceivers, on Earth, but things would remain white, or hot, or bitter. ", "Things would continue to be the way they are in observable respects even in the absence of perceivers. ", "2.1. ", "THE SENSIBLE QUALITIES OF REMOTE EXTERNAL PARTICULARS 23 Towards the end of the passage from the Categoriae, Aristotle adds a third claim: (3) Not only is the perceptible existentially prior to perception, but the perceptible is temporally prior as well. ", "And again, there is a focus on certain natural bodies that possess perceptual capacities. ", "Animals, natural bodies with perceptual capacities, have an elemental composition. ", "Animals are composed of the so-called elements, such as fire and water. ", "Fire and water, like the animals that are composed of them, are perceptible. ", "Before the animal is composed of its elements, and so comes to possess perceptual capacities and so perceive, the elements out of which the animal is composed would exist and be the potential objects of perception. ", "And so Aristotle concludes that the perceptible is not only existentially prior to perception but temporally prior as well. ", "The arguments in the Categoriae for (1)–(3) all emphasize that perception, though it may involve the presentation of the perceptible in sense experience, is nevertheless to be understood as the exercise of a capacity possessed by certain animate natural bodies, animals if not plants. ", "The corresponding arguments in the Metaphysica will themselves emphasize that perception is the exercise of a capacity possessed by animals. ", "However, in the Metaphysica, there is a crucial shift of focus. ", "While in the Categoriae, Aristotle emphasizes the way in which the natural bodies that possess perceptual capacities, and the elements that compose these bodies, are themselves perceptible, in the Metaphysica, however, Aristotle emphasizes instead the kind of capacity involved in perceiving the environment. ", "Specifically, sensory capacities are a mode of sensitivity to sensible aspects of the natural environment. ", "As such they are reactive capacities, they only ever act by reacting to the presence, in their environment, of the sensible object. ", "So there is a shift of focus from certain natural bodies possessing perceptual capacities to the objects that trigger the exercise of these capacities. ", "That the objects of perception are independent of perceivers perceiving them is brought out clearly in one of a battery of arguments that Aristotle brings to bear against Protagoras in Metaphysica Γ: And, in general, if only the sensible exists, there would be nothing if animate things were not; for there would be no faculty of sense. ", "Now the view that neither the sensible qualities nor the sensations would exist is doubtless true (for they are affections of the perceiver), but that the substrata which cause the sensation should not exist even apart from sensations is impossible. ", "For sensation is surely not the sensation of itself, but there is something beyond the sensation, which must be prior to the sensation; for that which moves is prior in nature to that which is moved, and if they are correlative terms, this is no less the case. (", "Aristotle, Metaphysica Γ 5 1010b30–1011a2; Ross in Barnes 1984a, 55–56) Aristotle's target is the claim that only the sensible exists, a doctrine that Aristotle 24 CHAPTER 2.

", "In the initial portion of the passage, the claim that nature is restricted to its sensible aspects is subject to a reductio ad absurdum.

", "How are we to understand the claim that only the sensible exists? ", "The conclusion of the reductio would follow from the principle that: If something exists, then it is perceived since a world without animals is a world without perception. ", "Perhaps the claim that only the sensible exists can be understood in terms of the weaker principle: If something exists, then it is possible that it is perceived Would the conclusion of the reductio follow from the weaker principle? ", "Whether it does depends on the sense of possibility involved. ", "In a world without perceivers, given how things are in such a world, it is not possible for anything to be perceived. ", "In order for something to be perceived, there must be perceivers, but there are none. ", "The weaker principle, understood in terms of this sense of possibility, would suffice for the conclusion of the reductio. ", "Nevertheless, in a world without perceivers, there is another reasonable sense in which it is possible for something to be perceived. ", "Even if no perceivers existed for the rest of eternity, the particulars in the natural environment could be of such a nature, or possess such a power, that had there been perceivers, they could have been perceived. ", "This latter thought is no aid to the Protagorean, however. ", "Aristotle thinks that the envisioned possibility is only intelligible against the background of a realist metaphysics. ", "Aristotle concedes to Protagoras that neither sensible qualities nor perceptions would exist if no perceivers exist. ", "There certainly would be no sensible qualities as Protagoras conceives of them, at least if he is a perceptual relativist. ", "But even if no perceivers exist, there would remain a \"substrata\" which retains the power to cause perceptions in animals with suitable sensory capacities. ", "Aristotle provides metaphysical and phenomenological grounds for the existence of such substrata. ", "The metaphysical grounds turn on the kind of capacity perceptual capacities are, reactive capacities, at least if perception is a mode of sensitivity to the sensible aspects of the natural environment. ", "If perception is a mode of sensitivity, as it must be if it is to be perception at all, the objects of perception must exist independently of perception and be the potential cause of perception.

", "Moreover, it does so by presenting itself as a mode of sensitivity to how things are, in sensible respects, independently of the perceiver. ", "It is unclear what Aristotle means by \"substrata\". ", "Does he mean persisting particular bodies like artifacts and natural objects? ", "Or does he mean something broader in this context, broad enough to include not only external particulars but their qualities as well? ", "Just because particulars must be independent causes of perception, it does not follow that they possess their sensible qualities independently of perception, or that their qualities can themselves be the cause of perception. ", "If, on the other hand, in the argument against Protagoras, \"substrata\" is meant to include not only external particulars but their sensible qualities, then external particulars possess their sensible qualities independently of being perceived.

", "The discussion in Metaphysica ∆ suggests this broader interpretation. ", "Similarly, sight is the sight of something, not 'of that of which it is the sight' (though of course it is true to say this); in fact it is relative to color or to something else of the sort.

", "THE SENSIBLE QUALITIES OF REMOTE EXTERNAL PARTICULARS 27 would not be a mode of sensitivity-unless perception takes as its object an external particular. ", "Let us begin with the difference in object. ", "Whereas as the objects of perception are particulars, the objects of knowledge are universal. ", "So whereas one may see the sun as it is at the moment of perception, burning white say, what one sees is a particular. ", "But particulars, according to Aristotle, are not known. ", "The objects of knowledge are universal in a way that precludes their being particulars. ", "To say that the objects of knowledge are universal is not to identify them with universals but rather only to accord them universal status. ", "They are universal in that they are predicated of many things (De Interpreatione vii 17a37–38). ", "They are said of a subject but are not in any subject (Categoriae ii 1a20–1b9). ", "It is not just knowledge whose objects are universal, this is a general feature of our cognitive capacities. ", "When one thinks that the sun is burning white, on thinks that thought not with the whiteness with which the sun actually burns but with a whiteness that the sun may share with the son of Diares, at least when viewed from a distance. ", "Aristotle's claim that perception and knowledge can be distinguished, in this way, by the nature of their objects is echoed Prichard: There seems to be no way of distinguishing perception and conception as the apprehension of different realities except as the apprehension of the individual and the universal respectively. ", "Distinguished in this way, the faculty of perception is that in virtue of which we apprehend the individual, and the faculty of conception is that power of reflection in virtue of which a universal is made the explicit object of thought. (", "Prichard, 1909) (For contemporary discussion of particularity and the content of perception see Brewer 2008, Martin 2002, Soteriou 2000, 2005, and Travis 2005.)

", "Sight just is the power or potentiality to present color in the awareness afforded by visual experience. ", "If color is the primary object of sight, and the objects of perception are particulars, then the colors that animals see are the colors that inhere in external particulars arrayed in their natural environment. ", "Looking up, you are dazzled by the whiteness of the late morning sun. ", "Your visual experience presents you with the sun's brilliant whiteness. ", "That is to say, it presents you with the whiteness that inheres in that heavenly body. ", "The color that you see, the brilliant whiteness of the sun, is not a universal but the actual instantiation of a chromatic quality by a particular. ", "In the present instance, the color that you see is the whiteness actually manifest by the sun on that late morning encounter with that heavenly body. ", "28 CHAPTER 2. ", "PERCEPTION AT A DISTANCE Here is an admittedly speculative rationale for the claim that the objects of perception are particulars. ", "Perhaps the background thought is that presentation in sensory experience is a kind of encounter and that one can only encounter particulars. ", "To grasp something and thereby perceive it by tactile means is for the perceiver to encounter something distinct from themselves. ", "That is the primitively compelling and phenomenologically vivid experience that leads the Giants to insist that only what can be handled and offers resistance to touch is real. ", "If one can only encounter particulars, then one cannot encounter the attribute of whiteness, being a nonparticular, at least not directly. ", "Instances of whiteness, manifestations of that quality in particulars in which it inheres, are, however, are encounterable particulars. ", "So one can encounter nonparticulars, such as the attribute of whiteness, at best indirectly, by encountering particular instances of it.

", "If this admittedly speculative rationale is behind Aristotle's twin commitments to colors being the objects of perception and to the objects of perception being particulars, then it is the most likely source of Cook Wilson's (1926, 336) doctrine that one can only apprehend universals in rebus (perceptual encounters, for Cook Wilson, are a species of apprehension). ", "Not only does perception and knowledge differ in object, they are the exercise of distinct kinds of capacities. ", "Perception may be the exercise of the perceiver's sensory capacities in a way that corresponds to the exercise of knowledge, but sensory capacities are capacities of a distinctive kind. ", "In Nietzsche's (1887) terminology, they are reactive capacities. ", "Sensory capacities only act by reacting to the presence of the sensible particular. ", "Aristotle made this point earlier by means of an analogy with combustion: Here arises a problem: why do we not perceive the senses themselves, or why without the stimulation of external objects do they not produce sensation, seeing that they contain in themselves fire, earth, and all the other elements, of which-either in themselves or in respect of their incidental attributes-there is perception? ", "It is clear that what is sensitive is so only potentially, not actually. ", "The power of sense is parallel to what is combustible, for that never ignites itself spontaneously, but requires an agent which has the power of starting ignition; otherwise it could have set itself on fire, and would not have needed actual fire to set it ablaze.

", "Our epistemic and cognitive capacities do not act by reacting. ", "They are active, not reactive. ", "Whereas we can choose to exercise our knowledge in a given circumstance, we are subject to what we perceive. ", "At first, it might seem that Kant (1781) would describe this difference between perception and knowledge as a difference between the exercise of receptivity and spontaneity. ", "A doubt arises, however, when we attend to what Aristotle has in mind by the exercise of our knowledge. ", "Consider a geometer-understood as one who possesses geometrical knowledge-and a non-geometer-understood as one who lacks such knowledge-looking at a diagram (see Figure 2.1). ", "The geometer can recognize the diagram as a proof of the Pythagorean theorem in a way that the nongeometer could not. ", "What makes for this difference is the geometer's possession of geometrical knowledge and their application of it to the presented diagram. ", "In recognizing a diagram as a proof, the geometer exercises their geometrical knowledge. ", "Notice that this pertains to the application of knowledge, not its acquisition. ", "But what is distinctive of Kant's position is the activity of the understanding in the acquisition of knowledge. ", "This element of Kant's thought, however, is not without precedent in Aristotle. ", "In Book iii of De Anima, Aristotle claims that just as perception is the assimilation of sensible form, the passive intellect is the assimilation of intelligible form. ", "Moreover, just as the assimilation of sensible form requires a medium, so too does the assimilation of intelligible form. ", "Specifically, Aristotle claims that it is the activity of the active intellect that functions as the medium through which intelligible forms may be assimilated. ", "So the acquisition of knowledge, as Aristotle conceives of it, involves the activity of the understanding-a mode of spontaneity that makes possible the reception of intelligible form. ", "According to Aristotle, the difference in object between perception and knowledge explains why perception and knowledge are the exercise of different kinds of capacities. ", "Since the objects of perception are external particulars, our perceptual capacities are only ever exercised in the presence of such particulars. ", "In this way, perception is a mode of sensitivity to particulars in the natural environment that not only exist independently of being perceived but whose natures and powers 30 CHAPTER 2. ", "PERCEPTION AT A DISTANCE Figure 2.1: Euclid's proof of the Pythagorean Theorem obtain independently of being perceived as well. ", "But since the objects of knowledge, and cognition more generally, are universal, the exercise of our epistemic and cognitive capacities need not be constrained in this way by the particular case. ", "2.1.3 Remote There are two senses in which the objects of perception may be remote: (1) The object of perception may be remote from the perceiver (2) The object of perception may be remote from the organ of sensation These claims are logically distinct. ", "Only the latter is a direct challenge to the Empedoclean principle, to be perceptible is to be palpable to sense. ", "Suppose as Aristotle claims, that the object of perception must be remote from the organ of sensation. ", "The object of perception may yet be in contact with the perceiver. ", "In some passages, the remoteness of perceptual objects is understood one way, but not in all passages. ", "When Aristotle criticizes the Empedoclean principle, he has in mind the remoteness of the object of perception from the organ of sensation. ", "When Aristotle distinguishes touch and taste as operating by contact in contrast with the distal senses such as sight and audition which operate not through direct contact but through an intervening medium, he has in mind the remoteness of the object of perception from the perceiver. ", "Indeed there are correlative notions of a medium. ", "When the remoteness at stake is the remoteness of the object of perception from the sense organ, this will notoriously lead Aristotle to maintain 2.2. ", "AGAINST THE EMPEDOCLEAN PRINCIPLE 31 that the perceiver's flesh is a medium through which the tangible qualities of bodies are felt. ", "But when the remoteness at stake is the remoteness from the perceiver, this will lead to Aristotle distinguishing touch and taste from sight and audition as not requiring a medium for their operation. ", "There is no inconsistency here. ", "Touch and taste are distinguished from sight and audition in that only the latter require the existence of an external medium for their operation. ", "But this is consistent with touch and taste requiring, at the same time, an internal medium for their operation. ", "Indeed, it is Aristotle's opposition to the Empedoclean principle that makes it possible for him to use contact to distinguish kinds of sensory modalities. ", "If all sensation operates by contact with its object, as Empedocles maintains, then it would be impossible to distinguish the contact senses and the distal senses in the way that Aristotle recommends. ", "The Aristotelean distinction between the contact senses and the distal senses presupposes and relies upon Aristotle's cases against the Empedoclean principle, to be perceptible is to be palpable to sense. ", "The distinction between the contact and distal senses having been made, Aristotle will argue that the distal senses are essential for animals with the capacity for locomotion: Both these senses [the contact senses, touch and taste], then, are indispensable to the animal, and it is clear that without touch it is impossible for an animal to be. ", "All the other senses subserve well-being and for that very reason belong not to any and every kind of animal, but only to some, e.g. those capable of forward movement must have them; for, if they are to survive, they must perceive not only by immediate contact but also at a distance from the object. (", "Aristotle, De Anima iii 12 434b22–25; Smith in Barnes 1984b, 62) In animals capable of locomotion, since nature distributes capacities in a purposive manner (De Anima iii 12 434a81–82), there is also the capacity to perceive at a distance so that the animal may move towards vital sources of nourishment, say. ", "If animals capable of locomotion lacked the capacity to perceive at a distance they would not survive since they lack, as well, the capacity to draw nourishment from where they are rooted like plants and stationary animals. ", "They must move towards their nourishment and flee from their predators. ", "The capacity to perceive at a distance is necessary for our well-being and continued existence.

", "Aristotle believes that a simple empirical observation constitutes such an argument: If what has colour is placed in immediate contact with the eye, it cannot be seen. (", "Aristotle, De Anima ii 7 419a13–14; Smith in Barnes 1984b) If a colored particular's being in contact with the eye blinds the perceiver to its color, then the colored particular must be at a distance from the perceiver if its color is to be seen. ", "And if the colored particular is remote from the perceiver, an intervening medium is necessary in order for the the organ of sight to be acted upon, as it must be if it is to be a mode of sensitivity: Colour sets in movement what is transparent, e.g. the air, and that, extending continuously from the object of the organ, sets the latter in movement. ", "Democritus misrepresents the facts when he expresses the opinion that if the interspace were empty one could distinctly see an ant on the vault of the sky; that is an impossibility. ", "Seeing is due to an affection or change of what has the perceptive faculty, and it cannot be affected by the seen colour itself; it remains that it must be affected by what comes between.

", "For they must, in any case, explain sense-perception through touch; so that it were better to say at once that visual perception is due to a process set up by the perceived object in the medium between this object and the sensory organ; due, that is, to contact, not to emanations. (", "Aristotle, De Sensu iii 440a16–21; Beare in Barnes 1984b, 9) Aristotle is making negative and positive claims in these passages. ", "The negative claim is that an object's contact with the eye is incompatible with its being seen. ", "2.2. ", "AGAINST THE EMPEDOCLEAN PRINCIPLE 33 The positive claim is that the eye is acted upon not by the object seen but by the intervening medium.

", "Whereas Democritus is committed to the denial of the positive claim, Empedocles is committed to the denial of the negative claim. ", "First, consider the positive claim that the existence of a suitable medium is necessary for sight. ", "This is meant to follow from the conjunction of the negative claim and a thesis about the nature of perceptual capacities. ", "Specifically, perceptual capacities are a mode of sensitivity. ", "They are reactive capacities. ", "As such, they are only ever exercised when acted upon by something external. ", "Since contact with a colored particular precludes perception of the particular and its color, the eye cannot be acted upon by the colored particular. ", "But the eye must be acted upon if the colored particular is to be seen. ", "Only the intervening medium could act upon the organ of sight in the requisite manner. ", "In the absence of an intervening medium, nothing would act upon the eye, and nothing would be seen. ", "Democritus is thus insensitive to the way in which sight is a reactive capacity. ", "Since sight is a reactive capacity, the organ of sight must be acted upon if the subject's potential for sight is to be actualized. ", "But the void that Democritus postulates precludes there being anything that could act upon the eye, the organ of sight. ", "Democritus is thus committed to denying the positive claim that in seeing a colored particular the intervening medium acts upon the organ of sight. ", "Second, consider Aristotle's negative claim that a particular's contact with the eye is incompatible with seeing its color. ", "We can distinguish specific and more general versions of the negative claim. ", "Whereas the specific claim is about color, the more general claim is about the objects of sense more generally, and thus holds of sound and smell as well: (1) A colored particular is imperceptible if it is in contact with the organ of sight; (2) A sensible particular is imperceptible if it is in contact with the relevant sense organ. ", "Consider first the specific claim about color. ", "Here the thought is that in order to have a colored particular in view the perceiver must have a view on that colored particular. ", "A colored particular's contact with the eye, the organ of sight, would preclude a point of view on that particular and its color. ", "It is a necessary condition for a perceiver to have a point of view on a particular and its color that the particular be at a distance from the perceiver. ", "To have a point of view on something is for that thing to be remote from one. ", "The specific claim about color is echoed in Aristotle's criticism of the likeness theory. ", "According to the likeness theory, perception is to be explained in terms of 34 CHAPTER 2. ", "PERCEPTION AT A DISTANCE the similarity of the elements with which the sense organ and the object of sense are composed. ", "The likeness theory is subject to a range of criticisms especially in the first book of De Anima; however, in De Sensu, Aristotle writes: For certainly it is not true that the beholder sees, and the object is seen, in virtue of some merely abstract relationship between them, such as that between equals. ", "For if it were so, there would be no need that either should occupy some particular place; since to the equalization of things their being near to, or far from, one another makes no difference. (", "Aristotle, De Sensu iii 446b10–13; Beare in Barnes 1984b, 20) Aristotle's complaint, here, is that equality, understood as complete compositional similarity of the sense organ and the object of sense, does not afford the perceiver with a point of view. ", "The perceiver's point of view on a particular depends upon that particular being at some distance from the perceiver. ", "Moreover, that point of view varies as the object of sense is near or far. ", "However, compositional similarity does not determine that the object of sense is any particular distance from the perceiver and hence fails to determine a point of view on that particular. ", "At least with respect to color vision, then, Aristotle's rejection of the Empedoclean principle, to be perceptible is to be palpable to sense, is unequivocal. ", "Far from being a necessary condition on sight, contact with a colored particular blinds us to that particular and its color. ", "Consistent with that denial, the Empedoclean principle may nevertheless be true of other objects of sense, such as taste and touch. ", "A more thoroughgoing rejection of the principle, then, would regard the specific claim about color as an instance of the more general claim about the objects of sense. ", "An object being in contact with the relevant sense organ, far from being a necessary condition for sensing that object, precludes it from being the object of sensation. ", "The claim here is general, applicable to all objects of sense-contact precludes sensation, to be palpable is to be imperceptible. ", "While Aristotle at least makes the specific claim about color, his complete case against the Empedoclean principle, to be perceptible is to be palpable to sense, may involve the more general claim. ", "The distinction between the specific and more general claim is relevant not only to the depth of Aristotle's case against the Empedoclean principle, but the distinction is relevant as well as to the relative plausibility of these claims. ", "Even if the more general claim should prove to be false-of taste or touch, say-the specific claim about color may yet be true. ", "It could turn out that vision is distinctive in being a sensory mode of presentation of the qualities of remote objects. ", "Thus, for example, Broad (1952) claims that a comparative phenomenology of our sensory capacities supports this view (even if he thinks that our phenomenology is misleading in this regard, and that the distinctive phenomenological character of vision is ultimately undermined by the common causal mechanisms underlying all of our sensory capacities). ", "Indeed, Broad might fairly point 2.2. ", "AGAINST THE EMPEDOCLEAN PRINCIPLE 35 out that the rationale so far offered for the specific denial about color appeals to a feature specific to vision, that in order to see something, the subject must have a point of view on it. ", "Aristotle's discussion of the special senses makes plain that he endorses the more general claim that contact precludes perception, that to be palpable is to be imperceptible: The same account holds also of sound and smell; if the object of either of these senses is in immediate contact with the organ no sensation is produced. ", "In both cases the object sets in movement only what lies between, and this in turn sets the organ in movement: if what sounds or smells is brought into immediate contact with the organ, no sensation will be produced. ", "The same, in spite of all appearances, applies also to touch and taste ... (Aristotle, De Anima ii 7 419a26–34; Smith in Barnes 1984b, 34) And later, in a discussion of why humans can only smell when they inhale, the general denial of the Empedoclean principle is invoked as a constraint on an adequate explanation: ... it is common to all not to perceive what is in immediate contact with the organ of sense ... (Aristotle, De Anima ii 9 421b16–18; Smith in Barnes 1984b, 38) Indeed, Aristotle's conviction that to be palpable is to be imperceptible drives him to deny that flesh is the organ of touch: In general, flesh and the tongue are related to the organs of touch and taste, as air and water are to those of sight, hearing, and smell. ", "Hence in neither the one case nor the other can there be any perception of an object if it is placed immediately upon the organ, e.g. if a white object is placed on the surface of the eye. ", "This again shows that what has the power of perceiving the tangible is seated inside. (", "Aristotle, De Anima ii 11 423b18–23; Smith in Barnes 1984b, 42) This is a surprising claim.

", "First, consider the following examples of Dennett's: Blindfold yourself and take a stick (or a pen or pencil) in your hand. ", "Touch various things around you with this wand, and notice that you can tell their textures effortlessly-as if your nervous system had sensor 36 CHAPTER 2. ", "PERCEPTION AT A DISTANCE out at the tip of the wand. ... ", "For an even more indirect case, think of how you can feel the slipperiness of an oil spot on the highway under the wheels of your car as you turn a corner. ", "The phenomenological focal point of contact is the point where the rubber meets the road, not any point on your innervated body, seated, clothed, on the car seat, or on your gloved hands on the steering wheel. (", "Dennett, 1993, 47) These are nice examples of artificially extending tactile consciousness beyond the limits of the perceiver's innervated body. ", "We feel the texture at the end of the pen, but not by feeling the pen in our hand. ", "If we accept Dennett's description of these cases, then contact with flesh is not necessary for something to be the object of tactile awareness. ", "While a good objection to the conjunction of Empedoclean principle and the claim that flesh is the organ of touch, this is too weak to establish Aristotle's counterprinciple, to be palpable is to be imperceptible. ", "Contact with the organ of touch may not be necessary for something to be the object of tactile awareness, but that is consistent with contact being sufficient for tactile awareness. ", "Nevertheless, Dennett's examples remove an important obstacle to the acceptance of Aristotle's position. ", "They make vivid the possibility of tactile awareness through a medium of objects remote from the organ of touch. ", "Aristotle's bold thought is that we are always already in the position described by Dennett. ", "When we feel the texture of a body with our fingertips, the phenomenological point of contact is remote from the organ of touch, no less than when we feel the texture of that same body with a pen. ", "Like the pen, the flesh of our fingertips is not the organ of touch but the medium through which the texture of the body is felt. ", "Aristotle's conception of touch is an internalization of the model provided by Dennett's examples. ", "Just as the phenomenological point of contact can be extended from the sense organ by means of an external medium, the phenomenological point of contact is always already extended from the sense organ by means of an internal medium. ", "The perceiver's flesh is an internal medium, the organ of touch residing within. ", "Indeed, Aristotle appeals to the internalization of an external medium to motivate the claim that flesh is not the organ of touch but its medium: To the question whether the organ of touch lies inward or not (i.e. whether we need look any farther than the flesh), no indication can be drawn from the fact that if the object comes into contact with the flesh it is at once perceived. ", "For even under present conditions if the experiment is made of making a sort of membrane and stretching it tight over the flesh, as soon as this web is touched the sensation is reported in the same manner as before, yet it is clear that the organ is not in this membrane.

", "Moreover, the color of the object is a sensible form enmattered in the object. ", "These distinct senses of material provide distinct potential grounds for rejecting the Empedoclean principle. ", "They thus also provide distinct potential contrasts with Aristotle's alternative conception of perception. ", "First, consider the distinct potential grounds for rejecting the Empedoclean principle, to be perceptible is to be palpable to sense.

", "In so doing we are jumping into the middle of things-both in the order of Aristotle's exposition, but also in that transparency is a common nature or power of the external medium that separates the perceiver and the remote object of vision. ", "There are philosophical reasons for considering the nature of the transparent. ", "First, Aristotle defines color in terms of the transparent. ", "Specifically, in De Anima ii 7 418a−b Aristotle defines color as the power to move what is actually transparent. ", "Our understanding of color is incomplete if we do not understand the state of the external medium, such as air or water, which is a precondition for the activity of color. ", "The effect of this incomplete understanding ramifies given Aristotle's avowed strategy of explaining perceptual capacities in terms of perceptual activities that are their exercise and to explain perceptual activities in terms of the objects of those activities (De Anima ii 4 415a14–22). ", "Second, given that color is the power to move what is actually transparent, there is an alteration that the external medium undergoes when in a transparent state as a result of the activity of color. ", "Suppose the alteration that the external medium undergoes when in a transparent state is imparted to the internal medium-the transparent medium that constitutes the interior of the sense organ, in the case of the eye, the vitreous humor. ", "Then we would have in place an important piece of the puzzle involved in interpreting the assimilation of sensible forms. ", "Moreover, progress can be made here while forestalling the controversies, which must eventually be faced, surrounding the metaphysics of De Anima ii 5. ", "Third, external particulars remote from the perceiver are arrayed in an external medium through which, when transparent, they appear. ", "Empedoclean puzzlement highlights the way in which this is a remarkable fact. ", "Attending to the details 41 42 CHAPTER 3. ", "TRANSPARENCY of Aristotle's discussion of transparency we may gain insight into his reaction to Empedoclean puzzlement about the sensory presentation of remote objects. ", "It is worth enumerating the reasons for considering Aristotle's discussion of transparency given its reception. ", "Some commentators suggest that Aristotle's discussion of transparency is of antiquarian interest only. ", "Others have expressed incredulity at the way Aristotle's account conflicts with the manifest facts of experience. ", "While leaving open the possibility of errors and omissions, we should try to understand Aristotle's account by attending to the phenomena as we understand it to be and by asking how that phenomena might have appeared as Aristotle describes it. ", "As a methodology, this is little more than a minimal exercise of charity. ", "However, it is worth stating explicitly if only because it has been routinely flouted. ", "Adhering to this precept yields and understanding of transparency that is sensible, phenomenologically adequate, and a reasonable approximation of the truth. ", "It is also a philosophically revealing exercise since to interpret Aristotle in this way is to use Aristotle's text as a means of attending to the phenomena under investigation. ", "3.2 Transparency in De Anima In De Anima, Aristotle defines the transparent as follows: ... by 'transparent' I mean what is visible, and yet not visible in itself, but rather owing its visibility to the colour of something else. (", "Aristotle, De Anima ii 7 418b4–6; Smith in Barnes 1984b, 32) First, one might be surprised that Aristotle defines transparency in terms the manner of its visibility, or the way in which it appears in perceptual experience. ", "Is it not more natural to think of transparency in terms of that through which remote objects appear-that is to say, not in terms of the manner of its visibility, but in terms of its being a condition on the visibility of other things? ", "We will return to this issue. ", "The second thing to remark about Aristotle's definition is the nature of the intended contrast between something being visible in itself and something owing it's visibility to another thing. ", "Aristotle does not have in mind here what he elsewhere calls incidental perception (De Anima ii 6 418a 20–23). ", "Seeing the transparent medium by seeing colors arrayed in it is not like seeing the son of Diares (a distant ancestor of Ortcutt, Quine 1956) by seeing a white speck. ", "Being the son of Diares is not sensible the way being transparent is (De Anima ii 6 418a 23–26). ", "Third, once we recover from our initial surprise at Aristotle defining transparency in terms of the manner of its visibility, and we consider the plausibility of that claim, quite apart from its status as a definition, we discover a potential insight. ", "I, at least, have the corresponding intuition about illumination. ", "I believe 3.2. ", "TRANSPARENCY IN DE ANIMA 43 we see the character of the illumination by seeing the way objects are illuminated. ", "The former is a state of the external medium whereas the latter is a property of a particular arrayed in that medium (though, of course, a property that the particular could only have given the state of the medium). ", "So when viewing a brightly lit pantry, one sees the the brightness of the pantry by seeing the brightly lit objects arranged in it. ", "Hilbert makes a similar phenomenological observation: Do we see how an object is illuminated or do we see the illumination itself? ", "On phenomenological grounds the first option seems better to me. ", "What we see as changing with the illumination is an aspect of the object itself, not the light source or the space surrounding the object. (", "Hilbert, 2005, 150–151) At the very least, then, the phenomenological claim enshrined in Aristotle's definition of transparency receives indirect support from the plausibility of the corresponding claim about illumination. ", "Finally, a question may be raised about the adequacy of Aristotle's definition. ", "While the phenomenological claim enshrined in Aristotle's definition may be plausible, it may be an inadequate definition of transparency if things other than the transparent are visible, though not visible in themselves, but owing their visibility to the colors of other things. ", "Consider Parmenides' striking description of the moon's reflectance: Night-shining foreign light wandering round earth. (", "Parmenides, dk 28b14; McKirahan 1994, 156) The moon is visible, but not by virtue of its own color, but by virtue of the color of the foreign light with which it shines. ", "So the moon, as described by Parmenides, satisfies Aristotle's purported definition of transparency, but the moon is not transparent. ", "The problem is general and does not depend on the veracity of Parmenides' description of the moon's reflectance (on the astronomical significance of this fragment see Popper 1998). ", "Consider any highly reflective surface, a mirror, say. ", "A mirror is visible, though not in itself, but owing its visibility to the colors of other things, the things whose colors are reflected therein. ", "But mirrors are not transparent. ", "Aristotle's claim about the manner in which the transparent is visible-that it owes its visibility to the colors of other things-may be true, and yet fail as a definition of transparency because it fails to provide a sufficient condition for something to be transparent. ", "The phenomenological claim is plausibly true not only of the transparent but of reflections as well. ", "Transparency is a nature or power common to different substances. ", "It is shared by liquids, like air and water, and certain solids and is incidental to the nature of each (De Anima ii 7 418b7–9). ", "A medium is actually transparent not due to its nature 44 CHAPTER 3. ", "TRANSPARENCY but due rather to the contingent presence of the fiery substance (De Anima ii 7 418b11–13). ", "The fiery substance is a substance, but insofar as it pervades a material medium, such as a body of air or water, it could not itself be a body, since two bodies cannot occupy the same space (De Anima ii 7 418b19). ", "The continual presence of the fiery substance is required for the transparency of the medium to persist. ", "Suppose I light a fuse with a cigar. ", "Prudence councils that I should remove myself from the scene. ", "Should I be enjoying the cigar I might take it with me. ", "But while the fuse would remain lit even when the cigar is removed, the air would not remain transparent when the fiery substance is removed. ", "When the fiery substance is removed, darkness supervenes (De Anima ii 7 418b18–21; De Sensu iii 439a18–21). ", "Not only does the persistence of transparency depend upon the continual presence of the fiery substance, but, arguably at least, it depends as well upon its continual activity (pace Sambursky 1958, Burnyeat 1995, 424). ", "That some states require continual activity to sustain them should be no surprise. ", "Consider Ryle's, (1949, 149), example of keeping the enemy at bay, or the connection between heat and molecular motion. ", "That the persistence of transparency depends upon the continual activity of the fiery substance may be taken to be implied by Aristotle's claim that light is the activity of the transparent qua transparent (De Anima ii 7 418b 9– 10). ", "Since transparency just is the presence of the fiery substance, the activity of the transparent qua transparent just is the activity of the present fiery substance. ", "A more speculative reason concerns the nature of fire. ", "In the Theaetetus Plato writes: ... being (what passes for such) and becoming are a product of motion, while not-being and passing-away result from a state of rest. ", "There is evidence for it in the fact that heat or fire, which presumably controls everything else, is itself generated out of movement and friction-these being motions. ... ", "Moreover, the growth of living creatures depends upon these same sources. (", "Plato, Theaetetus 153a−b; Levett and Burnyeat in Cooper 1997, 70) Here, Socrates is summarizing Heraclitus' view (on Cosmic Fire in Heraclitus see Wiggins 1982). ", "The first line is a general thesis of Heraclitean metaphysics. ", "Fire and living creatures are cited as examples meant to illustrate and motivate the more general thesis. ", "The being and continued existence of fire depends upon its activity. ", "Fire burns. ", "Burning, here, is not restricted to the burning of grosser forms of sublunary fire familiar from sensory experience. ", "Rather, burning is the most general activity of fire, even in its rarer forms. ", "So understood, should fire cease to burn, it would cease to be. ", "Similarly, to be a living creature is to act or, at the very least, to have a capacity to act. ", "Should a living creature lose its capacity to act altogether, it would cease to be. ", "While Aristotle denies the general claim that what passes for being is the product of motion (as well the claim that fire controls all), he can 3.2. ", "TRANSPARENCY IN DE ANIMA 45 nevertheless accept the description of the examples that illustrate and motivate the more general claim. ", "Thus, it is arguable that the passage contains the germ of his conception of a living being as refined and elaborated throughout De Anima. ", "If that is right, then it is at least open, in principle, for Aristotle to accept the corresponding claim about fire. ", "That the being of fire depends upon its distinctive activity, that a fire would cease to be should it cease to burn, is anyway, a prima facie plausible and phenomenologically compelling claim. ", "So conceived, however, the presence of the fiery substance will depend upon its continued activity. ", "Given the nature of fire, the continued presence of the fiery substance just is its continued activity. ", "Thus if the transparency of a medium depends upon the continued presence of the fiery substance, it will depend, as well, upon its continued activity. ", "Suppose that Heraclitean metaphysics is right to the extent that for fire, at least, to be is to burn. ", "Putting this together with Aristotle's denial that the fiery substance is a body, we arrive at a conception of the fiery substance as an incorporeal activity. ", "The presence of the fiery substance in a potentially transparent medium, be it air or water, just is the occurrence of this incorporeal activity, a kind of rarefied burning that instantaneously pervades the medium insofar as it is a unity. ", "That the presence of the fiery substance depends upon its activity provides Aristotle with the resources to explain the directionality of light. ", "That light has direction is vividly manifest in elementary facts about occlusion, reflection, and shadow and is fundamental to geometrical optics. ", "If the presence of the fiery substance did not depend upon its activity, then Aristotle would be hard pressed to explain the directionality of light in terms of the mere presence of the fiery substance, as Sorabji, echoing Philoponus, observes: Mere presence is not enough to explain the directionality of light. ", "Why, for example, are there any shadows at all, including the shadows that constitute night, and lunar eclipse? ", "For the sun and other fire-like stuff is present in the universe surrounding the earth, a surrounding all of which is transparent. ", "The requirement of presence does not explain why there is not light round the corners.

", "4.3 The Definition of Color Aristotle's explanatory strategy also importantly constrains the interpretation of his definition of color. ", "Color is the primary object of sight. ", "Given, Aristotle's avowed explanatory strategy, color, so understood, must be defined independently of color perception. ", "Before we consider Aristotle's definition, let us first briefly consider a small puzzle about the order of Aristotle's exposition of the special senses. ", "Aristotle's usual method of exposition would be to discuss the more fundamental of the special senses first. ", "And touch is fundamental in the sense that it is essential to all animals. ", "Not all animals see, but all animals have the sensory capacity for touch. ", "So on the usual method of exposition, one would expect Aristotle to begin his discussion of the special senses, not with sight and color as he does, but with touch and the tangible. ", "Why does Aristotle depart from the usual method of exposition? ", "What is its significance? ", "One idea is that Aristotle discusses the distal sense of sight first to motivate the need for an intervening medium before controversially arguing that a medium is in play in touch as well. ", "That idea is plausible, so far as it goes, but it gains significance once we realize that Aristotle's order of exposition is dictated by his response to Empedoclean puzzlement. ", "It is our perception of the colors inhering in remote external particulars that is the original source of such puzzlement. ", "Color perception is meant to be problematic in the way that touch could not be. ", "The departure from the usual method of exposition is the result of the consequent focus on color perception, and Aristotle will argue that touch, and not color perception, is the puzzling sensory modality. ", "Aristotle defines color as the power to move what is actually transparent (De Anima ii 7 418a31–418b33; ii 7 419a10–12). ", "Aristotle's definition, despite its brevity, has several distinguishable components. ", "Specifically, in his definition, Aristotle distinguishes: (1) a power to effect change-color (2) a patient of change, that which color acts upon-transparent media (3) a change that colors effect when acting upon transparent media-unspecified 4.3. ", "THE DEFINITION OF COLOR 77 (4) a condition on the media being acted upon by color-that the media be actually transparent Let me make some preliminary remarks about each of these components. ", "Some of these are observations, while others have a more aporetic character, raising issues or difficulties, directly or indirectly related to color's explanatory role given Aristotle's avowed explanatory strategy, in De Anima, of explaining perceptual capacities in terms of the perceptual activities that are their proper exercise, and explaining perceptual activities that are the proper exercise of our perceptual capacities in terms of the presentation of primary objects. (", "1) First, color is a power of external particulars, a power that is exercised in moving what is actually transparent. ", "A particular may possess this power even when it is not exercised-when the medium is potentially but not actually transparent, say, or when the particular is occluded from view by being an interior part of a body. ", "It is thus a kind of potentiality, or at least the grounds for one. ", "This is metaphysically significant since it implies that particulars retain their colors even when they are unseen, when in the dark or occluded from view, say. ", "As I argued in chapter 2, Aristotle uses the actual/potential distinction to sustain a perceptual realism. ", "Aristotle's definition would be the basis for distinguishing actual and potential color, potential color being the power to move what is actually transparent and actual color being that power's exercise, the moving of what is actually transparent. ", "And indeed Aristotle is keen to distinguish actual and potential color. ", "We have already seen an example of this in the De Sensu discussion of opacity (chapter 3.3). ", "Moreover, towards the end of an important passage (De Anima iii 2 426a2–26), Aristotle criticizes \"earlier students of nature\" for failing to distinguish actual and potential color. ", "It is only in failing to distinguish actual and potential color that they maintain that without sight there is no color. ", "Among the earlier students of nature, Aristotle thus undoubtedly has Protagoras in mind. ", "However, in Book iii, actual colors are the colors seen. ", "The actual/potential contrast as drawn by Aristotle's Book ii definition is between the power to move what is transparent and its exercise. ", "But color can move what is actually transparent and, in so moving, be visible in that medium and yet not be seen because there is no suitably placed, awake, and attentive perceiver. ", "This need not be a problem. ", "After all the actual and potential are said of in many ways. ", "But it does raise a question about how Aristotle is understanding actual and potential color. ", "Moreover, if, as the criticism of the earlier students of nature can seem to suggest, colors are most fully actual when perceived, it is at least not obvious that the colors are independent of perception in the way that is required by Aristotle's avowed explanatory strategy. (", "2) Second, color is the power to move what is actually transparent. ", "It is illumi78 CHAPTER 4. ", "COLOR nated media that color acts upon. ", "Color could not act upon the perceiver's organ of sight, at least not directly, since contact precludes sensation, to be palpable is to be imperceptible. ", "Thus was the moral of Aristotle's criticism of the Empedoclean principle. ", "While colors could not act upon the perceiver's sense organ, at least not immediately, they can nevertheless act upon the sense organ mediately, by acting upon an intervening medium. ", "So this aspect of Aristotle's definition of color, that color acts upon an intervening medium as opposed to the organ of sight, is a direct consequence of his case against Empedocles. ", "The contrast is usefully, if anachronistically, brought out as follows. ", "Colors are powers. ", "At least in this abstract regard, they are like Lockean secondary qualities, on one philosophically influential interpretation. ", "However, whereas Lockean secondary qualities are powers to elicit ideas in perceivers, colors, as conceived by Aristotle, are powers not to affect perceivers, but to affect something else, an illuminated medium, itself disposed to affect perceivers. ", "So conceived, colors may be powers, but they are less like Lockean secondary qualities than they are like, in the traditional post-Lockean vocabulary, tertiary qualities. ", "Locke characterizes these qualities as follows: The Power that is in any Body, by Reason of the particular Constitution of its primary Qualities, to make such a change in the Bulk, Figure, Texture and Motion of another Body, as to make it operate on our Senses differently from what it did before. (", "Locke, 1706, ii.8.23) Locke's (1706, ii 8 23) own examples of tertiary qualities are \"the Sun has a Power to make Wax white, and Fire to make Lead fluid\". ", "If colors were powers to affect illuminated media, then colors would be Lockean tertiary qualities, at least on a reasonable generalization of that notion. ", "Color, so conceived, would be the power of external particulars, by reason of their particular elemental composition, to make such a change to the illuminated medium so as to make it operate on our sense of sight differently from what it did before. (\"", "Before\", here, should be understood as a temporal metaphor for a modal claim-the illuminated medium affected by the color of a particular operates on color vision differently from the way it would if it were not affected by that particular's color.) ", "Colors, as conceived by Aristotle, are ways of affecting light. (", "3) Third, as Hicks (1907, 367) observes, by motion Aristotle does not mean locomotion or change in position. ", "Rather, in De Anima, kinēsis is Aristotle's general term for change of any kind. ", "Thus motion in Aristotle's definition means productive of change rather than productive of spatial movement, more narrowly. ", "Frustratingly, Aristotle does not directly specify the nature of the change color induces in the transparent medium it acts upon. ", "Indeed, in De Anima ii 7 the only effect of color discussed is the effect in terms of which the transparent is 4.3. ", "THE DEFINITION OF COLOR 79 defined-the transparent is not visible in itself, but owing its visibility to the color of another thing. ", "Is this change, the rendering visible of the transparent, sufficient to understand Aristotle's definition? ", "If it were, this would explain Aristotle's apparent silence about the nature of the change induced in the transparent by color-he merely says nothing further, having already specified the nature of the change in his definition of the transparent. ", "Is this credible? ", "What are the alternatives? (", "4) Fourth, the medium must meet a certain condition for color to act upon it-it must be actually transparent. ", "A doubt may be registered about the occurrence of transparency in Aristotle's definition given his avowed explanatory strategy. ", "Color is a proper object of sight, and, as such, partly defines the nature of sight. ", "It might reasonably be thought that color could only play a role in defining sight if it had a nature independent of sight. ", "But defining color in terms of the power to move what is actually transparent potentially threatens this order of explanation given the definitional connection between transparency and visibility. ", "It is on these grounds that Zabarella (1605) rejects Aristotle's definition (see Broackes, 1999, for discussion). ", "Begin with the one known effect that color has on what is actually transparent, the rendering visible of the transparent. ", "What is actually transparent is illuminated by the presence and activity of the fiery substance. ", "Aristotle's idea is that we see the illuminated media by seeing the colored particulars arrayed in it. ", "In chapter 3, I motivated Aristotle's idea by comparing it to the perception of the illuminant. ", "We see the character of the illuminant by seeing the way objects are illuminated. ", "Thus we see the brightness of the pantry by seeing the brightly lit objects arranged in it. ", "Similarly we see what is actually transparent, the external medium illuminated by the presence and activity of the fiery substance, by seeing the colors of external particulars arrayed in that medium. ", "How do colors render visible what is actually transparent? ", "Presumably by the colors of external particulars appearing through the illuminated medium. ", "The illuminated medium is visible because the colors of external particulars arrayed in that medium are visible. ", "Given his avowed explanatory strategy, color needs to be defined independently of the perceptual activity that takes color as its object. ", "Is this sufficient to rule out this change, the rendering visible of the transparent, from being the way that color acts upon transparent media in Aristotle's definition? ", "Not obviously. ", "Visibility is a matter of perceptual availability, not perception. ", "Right now, in my empty flat in Blackheath, an Eames chair is visible, but it is not seen since there is no one there to see it.

", "COLOR yet give the appearance of \"a closed curve in space\" to borrow Quine's (1951) apt phrase. ", "For what is it to be visible if not to be potentially perceived? ", "What are the alternatives? ", "Perhaps color colors the transparent. ", "The present suggestion claims of the external medium what Slakey (1961), Sorabji (1974), and Everson (1997) claim of the internal medium, the water of the eye, that it takes on the color of the perceived particular. ", "The suggestion can be understood in a number of ways. ", "Color could not color the transparent, if coloring involves the external medium taking on a surface color. ", "Surface color is the limit of the transparent, it is perceptually penetrable to the zeroeth degree. ", "It is perceptually impenetrable, defining a visual boundary in which and through which nothing further may be seen. ", "If the external medium took on surface color as the result of the color of the remote external particulars arrayed in it, then it would no longer be actually transparent. ", "A particular could not be seen through an opaque colored medium even if it is like-colored and is the agent of the chromatic change, the medium's taking on that surface color. ", "Perhaps in being colored, the transparent takes on, not a surface color, but a volume color. ", "So understood, the medium would be, if not perfectly transparent, then imperfectly transparent-objects could appear in it and through it, at least to some degree. ", "This effect thus has the virtue of at least being consistent with the actual transparency of the external medium. ", "However, it runs afoul of the directionality of the visible, that the perceptual availability of a particular's color depends in part upon the perceiver's point of view (a point upon which Aristotle crucially relies in his case against the Empedoclean principle). ", "If the external medium takes on a volume color corresponding to the surface color of an external particular residing within it, then that volume color could be observed even from an angle where the particular is no longer in view. ", "Suppose that the region between the perceiver and the remote external particular takes on the volume color corresponding to the surface color of that particular. ", "Another perceiver, looking at the scene side on, would observe the volume color of that region of the external medium, even if the colored particular was slightly out of view from their current vantage point (see Burnyeat 1995, 425). ", "But we normally observe no such thing. ", "The problem with color coloring the transparent is that it is inconsistent with the way that colors are perceptually available in the external medium: Either by being inconsistent with the medium being actually transparent or by being inconsistent with the directionality of the visible. ", "Sorabji (2004) has made a further important suggestion as to how color might color the transparent. ", "The color of the particular colors what is actually transparent, the illuminated medium, by that medium borrowing the color of that particular. ", "To say that the illuminated medium borrows its color from a particular is to 4.3. ", "THE DEFINITION OF COLOR 81 say that the source of the medium's color lies not within itself but in the particular. ", "For the medium to take on a surface color is for it alter in such a way that it takes on the power the possession of which is the source of that medium's color. ", "If the medium's colored is borrowed, however, its source lies not within itself but in another thing; specifically, in the power of a particular to alter the illuminated medium in a certain way. ", "Though metaphysically distinct, it faces a parallel difficulty. ", "Sorabji (2004) cites reflection as a case of borrowed color. ", "But reflection is a source of occlusion. ", "The reflection in a window can prevent a suitably placed perceiver from seeing what lies behind it. ", "In The Problems of Philosophy, Russell writes: Although I believe that the table is \"really\" of the same colour all over, the parts that reflect the light look much brighter than the other parts, and some parts look white because of the reflected light. (", "Russell, 1912, 2) Specular highlights may look brighter than the rest of the surface, but does that part of the surface corresponding to the specular highlight itself look brighter than the rest of the surface? ", "Is it even seen? ", "Or is that part of the surface rather occluded by a white specular highlight? ", "The whiteness would then be the color of the reflected light and not, as Russell suggests, the surface. ", "If the white of the specular highlight occludes the brown of the surface, then that part of the surface corresponding to the specular highlight does not appear white-it does not even appear! ", "If you were interested in some detail of that part of the surface corresponding to the specular highlight, you would need to change the viewing geometry (either by altering your position relative to the object or by altering the object's position relative to the illuminant) to get that detail into view.

", "Thus a medium could not at the same time borrow color in the manner of reflection and be actually transparent. ", "Recall this was the problem with Aristotle's definition of transparency (chapter 3.2).

", "Understood in this way, Sorabji's metaphor gives expression to the the phenomenological intuition that motivates Aristotle's definition of transparency (discussed in chapter 3.2). ", "Moreover, so understood, it is not a genuine alternative to the rendering visible of the transparent. ", "Observing that the one known effect of color, the rendering visible of the transparent, is psychological and rejecting the claim that color colors the transparent, Burnyeat suggests instead that color's effect on what is actually transparent is no real alteration, but a quasi-alteration: When the medium is actually transparent (diaphanēs), i.e. when the medium is such that colours can appear through it (phainesthai dia), they do appear through it. ", "At the same time, the transparent itself, the light, becomes visible in a way and coloured in a way-without being really coloured and, in consequence, without undergoing real alteration. ", "This non-real alteration-a quasi-alteration I shall call it-of the transparent consists in the fact that colours appear through it. ", "Here is a little experiment to help you understand the idea of quasialteration. ", "Fill a transparent glass with water and put it on a table. ", "Hold a red object a short distance away from the glass and look at it through the water. ", "The water in the glass is now serving as a medium within another medium (the surrounding air).

", "Now let the glass expand in your imagination to meet your eye, on one side, and the red object on the other. ", "The water will become the sole medium and you sill see the red object directly through it. (", "Burnyeat, 1995, 425) Color's effect on the illuminated medium is no real alteration. ", "The only effect that color has on the illuminated medium is that it appears through it.

", "THE DEFINITION OF COLOR 83 relational change without itself altering. ", "In this way, quasi-alteration is akin to Geach's (1969, 71–72) Cambridge change. ", "Both quasi-alteration, and the rationale offered on behalf of it, is surprisingly Protagorean. ", "Thus consider the reasoning that Socrates attributes to Protagoras in the Theaetetus: socrates: Well now, supposing such things as size or warmth or whiteness really belonged to the object we measure ourselves against or touch, it would never be found that this object had become different simply by coming into contact with another thing and without any change in itself. ... ", "As it is, you see, we may easily find ourselves forced into saying the most astonishing and ridiculous things, as Protagoras would point out or anyone who undertook to expound the same views. (", "Plato, Theaetetus 154b; Levett and Burnyeat in Cooper 1997, 171) Here we have a Protagorean reductio of the claim that sensible qualities inhere in external bodies. ", "Suppose, for the sake of reductio, that whiteness inheres in the external body that we perceive, the late morning sun, say. ", "If whiteness inheres in the sun, it could not differ in color without changing. ", "But the sun does become different without changing when measured by sight, or so Protagoras insists. ", "Thus whiteness does not inhere in the external body, but is constituted, in part, by an animal's perceptual relation to it. ", "Similarly, Burnyeat is asking us to suppose, for the sake of reductio, that color's effect on the illuminated medium is a material alteration and so something that inheres in that medium. ", "If it were, the illuminated medium, when acted upon by color, could not become different without changing. ", "But the illuminated medium does become different without changing when acted upon by color, or so Burnyeat insists is Aristotle's view. ", "The effect is no genuine alteration of the illuminated medium but is constituted by the color's appearing through that medium. ", "The Protagorean character of quasi-alteration and the rationale Burnyeat offers on behalf of it makes me hesitant to attribute the view to Aristotle. ", "It seems inconsistent with Aristotle's insistence (Metaphysica ∆ 15 1021a34–1021b3) that relations must be grounded: In order for a relation to obtain the relata must exist and have a nature independently of being so related (discussed in chapter 2.1.1). ", "By that principle, if the transparent medium is being appeared through, it must be some way in order for this to be so. ", "The insistence that relations be grounded may be dialectically ineffective against a committed Protagorean, but it should give us pause in attributing Protagorean quasi-alteration to Aristotle. ", "Fortunately, the attribution is unnecessary. ", "Consider how Burnyeat argues for the relational character of color's effect on illuminated media. ", "Burnyeat asks us to suppose, for the sake of argument, that color colors the transparent in the sense that the illuminated medium 84 CHAPTER 4. ", "COLOR takes on a volume color of the same hue as the opaque colored particular that appears through it. ", "The problem, according to Burnyeat, is that this runs afoul of the directionality of the visible: \"unlike the coloration that ensues if you pour red ink into the water, this coloration is not visible to other observers from other angles of vision.\" ", "The appearance of a color through the illuminated medium is relative to a point of view, a perspective that a suitably awake, attentive perceiver could adopt. ", "And Burnyeat invites us to conclude that not only is this relativity inconsistent with the illuminated medium taking on a volume color but with its undergoing any substantive change at all. ", "The argument may rest upon an insight, the directionality of the visible, but the reasoning remains invalid. ", "Color may alter the material state of the illuminated medium, and so undergo a substantive change that is not only consistent with, but explanatory of, the directionality of the visible. ", "To see this, first begin with an observation we made earlier. ", "Light is a state, the state of illumination. ", "The character of that state depends upon the contingent presence and activity of the fiery substance. ", "The character of the state of illumination depends upon the amount of the fiery substance present or, if this does not come to the same thing, its extent and degree of activity. ", "Since light depends upon the activity of the fiery substance, and activity can have a direction of influence, light inherits its direction from the direction of influence of the fiery substance whose activity constitutes its being and continued existence. ", "So there is nothing in light being a stable state that is inconsistent with its having a direction. ", "Light, understood as a state of illumination, may have a direction it inherits from the fiery substance, but, for all that has been said, this may not be the directionality of the visible. ", "To see that it is, we must first consider how color may affect light. ", "What material effect might color have on what is actually transparent? ", "Color is the power to move what is actually transparent. ", "What is actually transparent is illuminated by the presence and activity of the fiery substance. ", "So color is a power of particulars to alter the character of the illuminated medium in which they are arrayed. ", "The qualitative character of the illuminated medium is determined by the presence and activity of the fiery substance. ", "So in order to act on the character of the illuminated medium, color must somehow act on the fiery substance either by affecting the amount present in that medium or by promoting or restricting its activity to some degree. ", "If, as I have suggested, for fire, to be is to burn, these alternatives turn out to be equivalent-the amount of the fiery substance present just would be the extent and degree of its activity. ", "The different colors will thus affect the illuminated medium differently, by differently affecting the amount of the fiery substance present in that medium or differently promoting or restricting its degree of activity. ", "The present suggestion is consistent with the actuality of the transparent. ", "The contingent presence and activity of the fiery substance is what makes the potentially transparent actually transparent. ", "And being actually transparent is 4.3. ", "THE DEFINITION OF COLOR 85 materially sufficient for the perceptual availability of the colors of remote external particulars arrayed within the external medium. ", "Moreover, the present suggestion is not only consistent with the directionality of the visible, but provides the basis for its explanation. ", "The being of fire consists in its burning. ", "Burning is an activity. ", "And, as such, it has a direction of influence. ", "That the perceptual availability of a color depends upon the perceiver's point of view is due, in part, to the direction of influence that results from that particular's color altering the activity of the fiery substance. ", "So contra Burnyeat, an illuminated medium may be materially altered, by altering the amount of the fiery substance present or by promoting or restricting its activity to some degree, and this is not only consistent with the directionality of the visible but provides an explanation for it. ", "Finally, not only can the present suggestion explain the directionality of the visible, but it is also consistent with Aristotle's avowed explanatory strategy. ", "Given that strategy, color must be defined independently of the perceptual activity that takes color as an object. ", "Defining color as the power to alter the character of the illuminated medium by altering the presence and activity of the fiery substance within that medium makes no reference to perception whether in actuality or potentiality. ", "Nevertheless, the character of the illuminated medium being altered in this way is a material condition on the perceptual availability of the color to a suitably placed, awake, and attentive perceiver given the direction of influence of the fiery substance as affected by the chromatic power of the remote external particular. ", "A technical qualification is in order about the sense of alteration in play. ", "Let light and dark be states of a potentially transparent medium, light being the state that the medium is in when it is actually transparent and dark being the state that it is in when it is potentially if not actually transparent. ", "Since actual transparency is due to the contingent presence and activity of the fiery substances, the transition from light to dark is no qualitative alteration. ", "Light and dark may be inconsistent states, but they are not contraries from a common genus the way they would be if the transition were a genuine case of qualitative alteration. ", "Rather, the transition is a kind of privation. ", "When the fiery substance is removed, darkness supervenes. (", "As we shall see, an important consequence of this is how mixture so much as could be understood in Aristotle's theory of the generation of the hues, chapter 6.1.4.) ", "There is, however, a different though related sense of light and dark. ", "On this understanding, light and dark are not so much the state of being actually transparent and the state of being potentially though not actually transparent but rather their qualitative character. ", "Thus what is actually transparent is bright or light and darkness is the sensible aspect of the absence of fire. ", "The transition from light to dark, so understood, is a qualitative alteration. ", "Light and dark, understood as the sensible aspects of states of potentially transparent media, are contrary qualities drawn 86 CHAPTER 4. ", "COLOR from the same range of qualities. ", "Indeed they are opposites. ", "Light and dark are opposites in that they are at the extreme ends of this ordered range of qualities. ", "When a color affects light, this motion involves form and privation, light being the form determined by the presence and activity of the fiery substance and darkness being the privation of the light-giving fiery substance. ", "Color's effect on light thus involves form and privation-the activity of the form-giving fiery substance is promoted or restricted at least to some degree. ", "But affecting light in this way itself constitutes a qualitative alteration-promoting or restricting the activity of the fiery substance alters the qualitative character of the illuminated medium, by replacing one quality with a contrary from a common genus. (", "We shall return to such qualifications when we discuss De Anima ii 5 in chapter 8) If we set aside the suggestion that color colors the transparent, and that color's effect on illuminated media is a quasi-alteration, then we are left with three candidate effects: (1) The rendering visible of the transparent-making the transparent medium perceptually available. (", "2) The rendering visible of colored particulars arrayed in the transparent medium-making the colored particulars perceptually available. (", "3) Affecting the fiery substance by affecting the amount of it in the transparent medium or, if this does not come to the same thing, promoting or retarding its activity to some degree, or otherwise affecting its direction of influence as in cases of reflection or refraction. (", "1) is the only effect explicitly described in De Anima ii 7. (", "2), while not explicitly described in De Anima ii 7, is arguably presupposed by the one known effect-we see the transparent by seeing the colors of remote external particulars through it. (", "3) was elaborated only with resources available to Aristotle and while there is good reason to think that Aristotle is committed to this effect, he fails to make this commitment explicit. (", "1) and (2) concern something becoming perceptually available. ", "They are psychological effects at least in the extended sense that they concern potential psychological change-perceptual availability is, or at least involves, potential perception. (", "3) however is not psychological even in this extended sense but is, rather, a material change. ", "These psychological and material changes need not be inconsistent. ", "They may be part of formal and material explanations of one and the same phenomenon. ", "The visibility of color and the transparent, their perceptual availability, raised an issue about whether the definition could be understood in terms of these effects given Aristotle's avowed explanatory strategy. ", "Understanding Aristotle's definition in terms of (3) avoids this issue. ", "Before coming to a judgment about which, if any, of the three candidate effects Aristotle's definition of color should be understood in terms of, we need to consider 4.3. ", "THE DEFINITION OF COLOR 87 how this issue arises with another aspect of Aristotle's definition of color. ", "Specifically, this issue arises not only with the effects of color on the illuminated medium but also with the condition on the medium being acted upon by color. ", "External media are only receptive to the influence of color if they are actually transparent. ", "It is a necessary condition on the activity of color that the patient of this activity, the external medium, be in a certain state-that the medium be actually transparent. ", "Recall, Aristotle defines the transparent as that which is visible, though not visible in itself, but owing its visibility to the color of another thing (De Anima ii 7 418b4– 6). ", "Given the definitional connection between transparency and visibility, an issue arises as to whether this is consistent with Aristotle's avowed explanatory strategy. ", "Given that strategy, color needs to be understood independently of perception, but its definition specifies that the patient of its activity, the external medium, be visible, that is, potentially perceived. ", "Is potential perceptibility occurring in the definition in this way inconsistent with color, so defined, being independent of perception? ", "That is the question that Zabarella (1605) has bequeathed to us. ", "In order to address Zabarella's question, we need first to get clearer about the actual and the potential as applied to color and color perception. ", "Recall, according to Aristotle's definition, potential color is the power to move what is actually transparent and actual color is its exercise, the moving of what is actually transparent. ", "In Book iii, however, actual colors are the colors seen. ", "It is a persistent theme of Aristotle's that the actual and potential are said of in many ways. ", "So this need not be inconsistent, nor a change in view. ", "But it does raise a question about how Aristotle is understanding these ways of being actually or potentially colored. ", "Moreover, if the colors are most fully actual when perceived, as the Book iii doctrine can seem to suggest, then it is at least not obvious that colors are independent of perception in the way that is required by Aristotle's avowed explanatory strategy. ", "Begin with this latter issue. ", "As we shall see it is intimately connected with the former. ", "If color were most fully actual when perceived, then how could color be independent of perception in the manner required by Aristotle's avowed explanatory strategy? ", "Any apparent inconsistency, here, is merely apparent. ", "Aristotle is not claiming that a ripened tomato, say, is not actually red unless it is seen. ", "That was the mistake made by the \"earlier students of nature\" such as Protagoras. ", "Rather, the doctrine is that the tomato does not appear red unless it is seen (see Burnyeat 1982, 29, Ganson 1997). ", "When the tomato ripens it becomes actually red. ", "What is actualized in perception is that redness appearing, the manifestation of the red of the tomato in sensory consciousness. ", "There are thus two contrasts between the actual and the potential here. ", "Let \"c\" be a color, then: (1) A particular is actually1 c when it possesses the power to alter the illuminated media (in a manner characteristic of c as opposed to some other color, c′). ", "88 CHAPTER 4. ", "COLOR (2) A particular is actually2 c when it appears c in the perceiver's perceptual experience of it (as opposed to appearing c′, or not at all). ", "Notice that, though he does not deploy this vocabulary to describe the present case, this corresponds to Aristotle's distinction between first and second actuality: Now there are two kinds of actuality corresponding to knowledge and to reflecting. ", "It is obvious that the soul is an actuality like knowledge; for both sleeping and waking presuppose the existence of soul, and of these waking corresponds to reflecting, sleeping to knowledge possessed but not employed, and knowledge of something is temporally prior. (", "Aristotle, De Anima ii 1 412a24–26; Smith in Barnes 1984b, 21) First actuality corresponds to the possession of knowledge, second actuality corresponds to its exercise. ", "In De Anima ii 5, Aristotle will claim that the acquisition of knowledge, coming to know something, is a particular kind of change. ", "The transition from ignorance to knowledge is a sort of alteration of the rational animal insofar as one state of the animal has been replaced by another inconsistent with it. ", "Similarly, the ripening tomato in becoming red undergoes an alteration. ", "Unripened, it was green but potentially red. ", "Ripened, this potentiality is actualized. ", "The ripened tomato is red and not green. ", "The potentiality actualized by the tomato, its becoming red, consists in the tomato acquiring a particular power to affect illuminated media. ", "This is the first actuality of color. ", "Notoriously, Aristotle denies that the exercise of knowledge is an alteration, at least in the sense that becoming knowledgeable or red is: Also the expression 'to be acted upon' has more than one meaning; it may mean either the extinction of one of two contraries by the other, or the maintenance of what is potential by the agency of what is actual and already like what is acted upon, as actual to potential. (", "Aristotle, De Anima ii 5 417b2–5; Smith in Barnes 1984b, 30) The exercise of knowledge is not a destruction of something by its contrary like the chromatic change the ripening tomato undergoes. ", "In exercising knowledge, that knowledge is preserved. ", "The subject does not become ignorant in exercising their knowledge, and so retains that knowledge in its exercise. ", "Moreover, there is a sense in which that knowledge is not only preserved but actualized in its exercise. ", "A subject realizes their nature as knowledgeable about a certain topic by applying their knowledge of it in a reasonable manner given the practical circumstances. ", "So, for example, Theaetetus realizes his nature as a geometer by recognizing a diagram as a proof. (", "Exactly what Aristotle means, here, will be discussed in chapter 8.) ", "So a transition to second actuality is not an alteration the way a transition to first actuality is. ", "Moreover, this claim in De Anima ii 5 is made in the context of an extended 4.3. ", "THE DEFINITION OF COLOR 89 comparison of knowledge and perception. ", "Perceptual activity such as seeing, the exercise of the perceiver's capacity for sight, is a second actuality the way that the exercise of knowledge is. ", "Seeing is more than a destruction of something by its contrary. ", "It is the preservation and actualization of a potentiality. ", "In seeing a colored particular, a perceiver exercises their capacity for sight and so realizes their nature as a perceiver. ", "So a perceiver coming to see a colored particular does not undergo an alteration, at least not merely. ", "So, presumably, the color of the particular coming to appear in the perceiver's experience of is no mere alteration either. ", "So in possessing a power to alter illuminated media, a particular is actually colored-it actually has the color constituted by the power to affect light in that way. ", "Coming to possess this power is an alteration, and the possession of this power is a first actuality. ", "This first actuality of color is itself a potentiality since the power either is, or is the principle that grounds, a potentiality, the potential of that particular to affect light in a certain way. ", "In acquiring the power to affect light in a certain way, the colored particular also acquires the derived power to mediately affect organs of sensation sensitive to such alterations in illuminated media. ", "When the particular alters the illuminated medium, and there is a suitably placed, awake perceiver who is attentive to the sensitivity of their eyes to such alterations, the color appears in their experience of that particular. ", "This is the second actuality of color. ", "The second actuality of color is triggered by the exercise of the power to mediately affect the eye that derives from a power to affect the intervening medium. ", "This more fundamental power is a power that a particular may have even in the absence of perceivers. ", "The colors are not most fully real when seen. ", "This was the mistake of the \"earlier students of nature\". ", "What is actualized in perception is the presentation of color in sensory consciousness. ", "If a particular is actually colored merely by possessing the power to affect illuminated media in a certain way, then Aristotle's doctrine is consistent with the explanatory demand that color be understood independently of perception. ", "As Burnyeat (1982, 29, n13) observes, this doctrine is supported by \"Aristotle's central claim ... that the sensible object must already be in actuality what prior to the act of perception, the sentient subject is potentially.\" ", "Thus Aristotle writes: As we have said, what has the power of sensation is potentially like what the perceived object is actually; that is, while at the beginning of the process of its being acted upon the two interacting factors are dissimilar, at the end the one acted upon is assimilated to the other and is identical in quality with it. (", "Aristotle, De Anima ii 5 418a3–6; Smith in Barnes 1984b, 31) In what sense sensation is like the perceived object actually is may at this point be unclear. ", "This is the sense in which the perceiver assimilates sensible form. ", "In 90 CHAPTER 4. ", "COLOR assimilating the sensible form without the matter of the remote external particular, the perceiving subject, or at least their perceptual experience, becomes like the sensible particular. ", "In a sense that I will explain in chapter 9, color shapes sensory consciousness. ", "What is presently important, however, is Aristotle's requirement that the remote external particular be actually colored prior to the perceiver's experience of it. ", "And as we saw in chapter 2, Aristotle advances a battery of arguments for this claim in Metaphysica Γ, and it is central to his perceptual realism. ", "Finally, consider Aristotle's criticism of the \"earlier students of nature\": The earlier students of nature were mistaken in their view that without sight there was no white or black, without taste no savour. ", "This statement of theirs is partly true, partly false: 'sense' and 'the sensible object' are ambiguous terms, i.e. may denote either potentialities or actualities: the statement is true of the latter, false of the former. ", "This ambiguity they wholly failed to notice. (", "Aristotle, De Anima iii 2 426a24–26; Smith in Barnes 1984b, 46–47) According to the \"earlier students of nature\", without sight there is no white or black. ", "Aristotle's response parallels his response to Protagoras in the Metaphysica. ", "He is at once concessionary but concludes as well that these concessions are only intelligible given a background realist metaphysics. ", "Here, Aristotle claims that the \"earlier students of nature\" are partly right and partly wrong, owing to the ambiguity of \"sense\" and \"sensible object\". ", "Aristotle claims that both \"sense\" and \"sensible object\" can be understood either as potentialities or actualities. ", "Moreover, as we have seen, the actual and the potential are themselves said of in many ways, adding further scope for ambiguity. ", "Aristotle claims that the doctrine of the \"earlier students of nature\"-that without sight there is no white or black-is true of actualities, but false of potentialities. ", "What is the sense of actual upon which this doctrine comes out true? ", "Attending to context helps. ", "Aristotle's criticism of the \"earlier students of nature\" occurs at the end of an extended passage where the actuality of color is understood as the actualization of that color in perception, its presentation in visual consciousness. ", "Correspondingly, the actuality of sight must be understood as the seeing of that color. ", "So understood, the doctrine of the \"earlier students of nature\" is that no colors are present in visual consciousness unless they are actually seen. ", "However, this carries with it no commitment to Protagorean metaphysics. ", "So understood, the doctrine is consistent with a perceptual realism where colors actually inhere in external particulars prior to being perceived. ", "Not only is this doctrine consistent with perceptual realism it is only intelligibly sustained against the background of a realist metaphysics. ", "If a color's presentation in visual consciousness is the effect, at least in part, of a colored particular acting upon an illuminated medium, then the particular must actually be colored prior to its actualization in perception, prior, that is, to the perceiver's experience of 4.3. ", "THE DEFINITION OF COLOR 91 it. ", "It is not true that without the capacity for sight, there are no visible qualities, that is, qualities that are potentially seen. ", "White and black things are of such a nature that had their been suitably placed, awake, attentive viewers in an illuminated environment, they could have been perceived. ", "If the colors are not most fully real when seen, as the \"earlier students of nature\" maintained, then why describe the presentation of the colors in visual consciousness in terms of actuality? ", "Allow me to make a conjecture. ", "As we shall see in chapter 8.3, the transition to second actuality is a kind of perfection or realization of a thing's nature. ", "Color is a species of the visible. ", "Not the only species. ", "Color is visible in the light, and the luminous is visible in the dark. ", "As a species of visibilia, a particular's color being seen might reasonably be understood as a perfection of its nature. ", "If the visible is to be seen, then colors in being seen realize their nature as visibilia and so are perfected. ", "We are now in a position to provide a provisional answer to Zabarella's question. ", "Given the definitional connection between transparency and visibility, how can transparency figure in Aristotle's definition of color consistent with his avowed explanatory strategy of explaining perceptual capacities in terms of perceptual activities, and explaining perceptual activities in terms of their objects? ", "In having visibility figure in the definition of color, has Aristotle failed to specify the object of color perception independently of that experience? ", "There is no inconsistency here. ", "For something to be visible is to have such a nature that a suitably placed, awake, attentive, viewer in an illuminated environment could see that thing. ", "A visible thing possesses such a nature prior to being seen and would retain that nature even when shrouded in darkness, or occluded from view, or in the absence of suitably placed perceivers, or when suitably placed perceivers are asleep or otherwise inattentive, or even if there were no animals with the capacity for sight. ", "As Aristotle argues in Metaphysica Γ, to be visible, to be potentially perceived, is to possess a \"substrata\", understood broadly enough to include natures and powers, prior to perception. ", "Aristotle leaves unspecified color's effect on illuminated media. ", "Setting aside color coloring the transparent and quasi-alteration, we saw that three candidates remain: (1) The rendering visible of the transparent-making the transparent medium perceptually available. (", "2) The rendering visible of colored particulars arrayed in the transparent medium-making the colored particulars perceptually available.

", "Aristotle's avowed explanatory strategy puts pressure on the psychological alternatives since the definition of color formulated in terms of either, while not flatly circular, at least appears like \"a close curve in space\". ", "We have seen, however, that there is a sense of potential perception whose definitional connection with color would be consistent with Aristotle's avowed explanatory strategy. ", "This sense of potential perception is inconsistent with a Protagorean metaphysics, and involves the material nature of what is potentially perceived. ", "This understanding of visibility is not only consistent with a material change in illuminated media but it requires the existence of an underlying material nature as a \"substrata\" and agent of that change. ", "While (1) and (2), so interpreted, would be consistent with Aristotle's avowed explanatory strategy, interpreting Aristotle's definition of color in terms of (3), understood in such a way as to be not only consistent with, but explanatory of, the psychological effects (1) and (2), would provide the best overall coherence. ", "The idea would be that colored particulars have a material nature required to ground a power to affect the amount, activity and direction of influence of the fiery substance in illuminated media. ", "And in so affecting the fiery substance, the particular, or at least its color, is perceptually available-or would be to suitably placed, awake, and attentive viewers. ", "While there are internal pressures that support this interpretation, an important question remains: What is the material nature the possession of which underlies a particular's power to affect the amount, activity, and direction of influence of the fiery substance in illuminated media? ", "Aristotle is silent on this matter, and this issue remains unaddressed in De Anima. ", "If this were the end of the matter, much of the foregoing would be purely speculative. ", "Arguably, however, this unfinished business is addressed by the De Sensu doctrine that color resides in the proportion of the transparent that exists in all bodies. ", "It is the possession of the proportion of the transparent that exists in all bodies that endows a remote external particular with the power to affect the amount, activity, and direction of influence of the fiery substance in illuminated media. ", "And in so affecting the fiery substance, the particular, or at least its color, is perceptually available-or would be to suitably placed, awake, and attentive viewers. ", "So the possession of the proportion of the transparent that exists in all bodies is the material nature that underlies a colored particular's visibility, a material nature the particular may possess even in the dark or in the absence perceivers. ", "4.4. ", "COLOR AND TRANSPARENCY 93 4.4 Color and Transparency One of the novel claims of De Sensu is that color resides in the proportion of transparent that exists in all bodies.

", "If rotated counterclockwise, the pattern is reversed with the innermost arcs now forming violet rings and the outermost reddish rings. ", "The apparent colors of Benham's spinning disk are the \"subjective colors\" first described by (Fechner, 1838) and, hence, are also sometimes described as \"Fechner-Benham colors\".

", "The subjective colors of the Benham disk are not completely understood (for a review of some of the color science see von Campenhausen and Schramme, 1995).

", "The fundamental problem with the present account is that it too closely models color combination in terms of the appearance of a color through an imperfectly transparent medium with a given volume color. ", "The surface color a figure can be seen through water or mist, just as the radiant color of the sun can be seen through fog or a cloud of smoke.

", "At the same time, it signifies a radical break with the older point of view. ... ", "That \"coming-to-be\" and \"perishing\" played an essential role in all previous doctrines is the natural conclusion to be drawn from a reading of his poem; and this view is fully confirmed by the fragments of Xenophanes and Heraclitus. ", "In contrast to the denial of Parmenides, Anaxagoras, and Empedocles these earlier men speak unhesitatingly of \"generation,\" \"growth,\" and \"death.\" ", "The fundamental difference between the sixth and fifth centuries lies not in the abandonment of monism for plurality, but in the passage from a world of birth and death to one of mixture and separation. (", "Kahn, 1994, 154–155) Aristotle's preferred account of the generation of the hues is modeled on his preferred account of elemental composition, itslef a return to the sixth century bc view. ", "On Aristotle's view, the Emepdoclean tetrad-water, earth, air, and fire-are only elements so-called. ", "Strictly speaking, elements are the simple primary ingredients of a compound (Metaphysica ∆ 3 1014a26ff). ", "So understood the real elements are the primary opposites: Hot, Cold, Dry, and Wet. ", "The so-called elements, water, earth, air, and fire, are the result of the combination of these opposing principles. ", "Thus water is Cold and Wet, earth is Cold and Dry, air is Hot and Wet, and fire is Hot and Dry. ", "Since the Empedoclean tetrad are only elements so-called, they are subject to a cycle of transformation familiar from ancient times. ", "In a passage self-consciously recounting the older view, Plato describes the cycle of elemental transformation thus: In the first place, we see that what we just now called water, by condensation, I suppose, becomes stone and earth, and this same element, when melted and dispersed, passes into vapor and air. ", "Air, again, when inflamed, becomes fire, and, again, fire, when condensed and extinguished, passes once more into the form of air, and once more air, when collected and condensed, produces cloud and mist-and from these, when still more compressed, comes flowing water, and from water comes earth and stones once more-and thus generation appears to be transmitted from one to the other in a circle. (", "Plato, Timaeus 49b−c; Jowett in Hamilton and Cairns 1989, 1176) 6.1.

", "If one thought that ice is the result of water compacting with the increase in cold, this would at least leave you open to the idea that compacting water can result in solid bodies with fixed boundaries. ", "However, the passage does not mention ice, and it can still seem mysterious how compacting water can result in solid bodies composed of earth and stone. ", "What experience, available to the ancients, could be vivid enough to elicit conviction in this elemental transformation? ", "Consider a river destroyed by drought, a fearful and ruinous experience for agrarian societies. ", "An ancient spectator to this tragedy would watch as the river contracted, day after day, leaving in the end, nothing but the sun parched stones and earth that once constituted the river's bed. ", "Such an experience, I conjecture, would be vivid and significant enough to produce cosmic conviction. ", "The desalination of brine in salt production, a procedure dating back over eight millennia, is an equally marvelous, if less tragic, experience that might elicit conviction in this elemental transformation as well. ", "Aristotle regards the continuous transformation of the Empedoclean tetrad into one another as an established fact of observation. ", "So conceived, they could not be the Parmenidean beings that Empedocles understands them to be. ", "The combination of the so-called elements, is no longer understood in terms of the juxtaposition of unaltering, ungenerated, and imperishable beings. ", "Water, earth, air, and fire transform into one another and in so doing interfuse. ", "And it is complete interfusion that is mixture properly so-called. ", "In a compound body composed of different items from the Empedoclean tetrad, the so-called elements combine by interfusing, that is, by blending or mixture. ", "With respect to elemental composition, Aristotle's view thus represents a return to the sixth century bc world of birth and death. ", "Aristotle's preferred model of the generation of the hues should be understood set against this larger reaction to Parmendiean skepticism about growth and decay. ", "It is because he regards combination and separation (understood on the model of juxtaposition) as an imperfect surrogate for growth and decay (De Generatione et Corruptione i 10), that he understands elemental composition instead in terms of mixture. ", "And it is natural, if not inexorable, that he should have a parallel understanding of chromatic composition.

", "Their lesson might very well be: Chromatic composition involves the mixture of light and dark only in a Pickwickian sense of mixture. ", "Qualties are inseparable from the substances in which they inhere, but the ingredients of a mixture must admit of separation. ", "Since qualities and states do not admit of separate existence, neither do they admit to mixture: Now we do not speak of the wood as combined with the fire, nor of its burning as a combining either of its particles with one another or of itself with the fire: what we say is that the fire is coming-to-be, but the wood is passing-away. ", "Similarly, we speak neither of the food as combining with the body, nor of the shape as combining with the wax and thus fashioning the lump. ", "Nor can body combine with white, nor (to generalize) properties and states with things; for we see them persisting unaltered. ", "But again white and knowledge cannot be combined either, nor anything else which is not separable. (", "Indeed, this is a blemish in the theory of those who assert that once all things were together and combined. ", "For not everything can combine with everything. ", "On the contrary, both of the constituents that are combined must originally have existed in separation; but no property can have separate existence.) (", "Aristotle, De Generatione et Corruptione i 327b12–22; Joachim in Barnes 1984a, 30–31) 6.1. ", "ARISTOTLE'S THREE MODELS 135 Qualities and states do not mix with the things whose qualities and states they are. ", "Nor can qualities and states mix with other qualities and states. ", "Only that which admits of separate existence can be combined in mixture but qualities and states are inseperable from the things whose qualities and states they are. ", "The argument, here, is the basis for rejecting Emepocles' conception of the cosmic cycle. ", "The world, as we experience it, is in an intermediate stage of the cosmic cycle, where neither Love nor Strife dominate. ", "At times in the cosmic cycle Strife dominates, and everything is scattered. ", "At others Love dominates, and everything is combined in perfect Parmenidean sphere. ", "But, according to Aristotle, the latter is not possible since not everything can be combined in the envisioned manner. ", "Only what admits of separate existence may be combined, but not every category of being admits of separate existence. ", "Even the divine glues of harmony could not bind what what does not admit of separate existence. ", "There are limits, apparently, to even Aphrodite's Love. ", "While Empedocles is the plausible target of criticism here, Aristotle's argument would also be the basis for rejecting the Way of Mortal Opinion. ", "According to the Way of Mortal Opinion \"the whole world of sense\" in which appear \"earth, heaven, sun, moon, and stars\" is the result of the \"blending\" or mixture of light and dark.

", "The colors are inseparable from the particulars in which they inhere. ", "But only that which can exist separately may be combined in a mixture.

", "There is no positive determinant, be it a cosmic principle or an element, for darkness. ", "This is partly a manifestation of Aristotle's insight concerning the connection between illumination and visibility. ", "The fiery substance illuminates the transparent medium and only thus are the particulars arrayed in that medium visible. ", "If the fiery substance is removed, darkness supervenes. ", "Aristotle's contribution has an additional source in the general metaphysics of change presented in Book i of Physica. ", "All change involves opposition, but the general form of opposition involved in all change involves form and privation. ", "One may wonder how these claims could be true together. ", "Consider a kind of substance. ", "The generation of a kind of substance involves form and privation, but as substances have no opposites, there is no opposition. ", "Form and privation seems to 136 CHAPTER 6. ", "THE GENERATION OF THE HUES be a more general distinction than the distinction between opposites. ", "There may be more to opposition than form and privation, but opposition itself involves form and privation. ", "Thus Aristotle understands the traditional opposites, discussed by Parmenides and Empedocles among others, in terms of form and privation. ", "In the opposition of light and dark, light is the form determined by the presence and activity of the fiery substance and darkness is the privation of the light-giving fiery substance. ", "That darkness is determined by the absence of the fiery substance rather than the presence of Night or water, raises the second puzzle about the sense of mixture involved in the generation of the hues. ", "If darkness is the sensible aspect of the absence of fire, then in what sense can brightness be mixed with darkness? ", "Perhaps by mixture of light and dark Aristotle just means relative brightness, but that would be a Pickwickian sense of mixture. ", "The lesson of the first puzzle is that qualities and states cannot be combined in a mixture. ", "But suppose that a quality or state is determined by the presence and activity of something that admits of separate existence. ", "While qualities such as light and dark could not mix, perhaps the determinants of these qualities mix, at least if they admit of separate existence. ", "The lesson of the second puzzle is that absences do not mix. ", "But while you cannot mix an absence, you can mix things which are more or less resistant to the illuminating presence and activity of the fiery substance. ", "Earth resists the presence and activity of the fiery substance, just as air is receptive to it. ", "You cannot mix absences, but you can mix something which will preclude the presence of the fiery substance or at least retard its activity. ", "That is to say you can mix things which differ in the degree of their transparency, the degree to which they are receptive to the illuminating presence and activity of the fiery substance. ", "Read in light of the De Sensu doctrine that color resides in the proportion of the transparent that exists in all bodies, the lessons of our two puzzles might be jointly satisfied in the following manner. ", "Consider mixing two ingredients with different degrees of transparency that result from their different elemental compositions. ", "Prior to the mixture, the ingredient with a greater degree of transparency will be brighter in color than the ingredient with a lesser degree of transparency which will be darker. ", "Combining these ingredients in a mixture results in a mixed body with an intermediate degree of transparency and hence a color intermediate between the lighter and the darker. ", "But it is not light and dark that are mixed but elemental compounds with different degrees of transparency. ", "Thus the lesson of the first puzzle is satisfied. ", "And it is not the presence and absence of the fiery substance that is mixed but, again, elemental compounds with different degrees of transparency, different degrees to which they are receptive to the presence and activity of the fiery substance.

", "While I believe that this is the best way to understand (or perhaps develop) Aristotle's account of the generation of the hues in terms of mixture, a residual doubt remains. ", "On the present development of Aristotle's model, chromatic composition is understood in terms of mixing ingredients whose elemental compositions determine their different degrees of transparency. ", "When ingredients combine in a mixture, they alter one another. ", "But what makes for chromatic composition is that the ingredients in the mixture are altering one another's degree of transparency, the degree to which they are receptive to the illuminating presence and activity of the fiery substance. ", "But not every mixture of bodies results in mutually altering their degree of transparency in proportion with the corporeal mixture. ", "There are certain colors that artists cannot achieve by mixing pigments (Meterologica iii 2 372a2–9). ", "When the proportion or ratio of bodies mixed does not correspond to the degree to which the mixed bodies altered one another's degree of transparency this is due to a kind of material recalcitrance. ", "The possibility of material recalcitrance establishes that not every combining of bodies in a mixture is a combining of their color in that mixture. ", "Only certain bodily mixtures are color combinations, properly so called. ", "Only bodily mixtures where the proportion or ratio of bodies mixed correspond to the degree to which they alter one another's degree of transparency are genuine methods of color combination.

", "THE GENERATION OF THE HUES The ordering of the intermediate colors between the extremes of light and dark is not structured as a continuum. ", "This is a general thesis about sensible qualities. ", "All sensible qualities are understood to be ordered in a range of contrary qualities between opposites. ", "And Aristotle maintains that there are only ever finitely many species from a given range (De Sensu vi 445b21–446a19). ", "Specifically, there are seven species of color: Savours and colours contain respectively about the same number of species. ", "For there are seven species of each, if, as is reasonable, we regard grey as a variety of black (for the alternative is that yellow should be classed with white, as rich with sweet); while crimson, violet, leekgreen, and deep blue, come between white and black, and from these all others are derived by mixture. (", "Aristotle, De Sensu iv 442a20–442a25; Beare in Barnes 1984b, 12) Three of these are the colors of the rainbow-crimson, violet, and leek-green, though some report yellow coming between crimson and leek-green (Meterologica iii 2 372a8–10). ", "In the passage, Aristotle regards gray as an achromatic hue, indeed it is a kind of black, presumably because it is less bright than white and so reckoned a privation the way black is. ", "In other works, its achromatic character is overlooked, gray counting as an intermediary color just as much as yellow (Categoriae, x 12a18; see also Topica i 15 106b5, Metaphysica i 1056a27). ", "So there are seven species of color-white, yellow, crimson, violet, leek-green, deep blue, and black. ", "Corresponding to the five intermediate species are simple ratios of light and dark. ", "So far we have, in line with ancient tradition, two primary colors, white and black, or better yet, light and dark. ", "The two primary colors are opposites at the extreme ends of an ordered range of colors. ", "In addition to the two primary colors there are five intermediate colors that are the result of mixing the primary colors light and dark in simple ratios. ", "Following Sorabji (1972, 297) call these the secondary colors. ", "In addition to primary and secondary colors, Aristotle seems to recognize a third group of colors. ", "Moreover, these seem to be the result of mixing secondary colors: \"crimson, violet, leek-green, and deep blue, come between white and black, and from these all others are derived by mixture\" (De Sensu iv 442a25; Beare in Barnes 1984b, 12). ", "So the tertiary colors are all the colors other than the primary and secondary colors and are the result of a mixture of secondary colors. ", "The Aristotelian color scheme raises a number of questions. ", "First, if the mixture of light and dark in simple ratios determines the secondary colors whose mixture in turn determines the tertiary colors, is it possible to determine the tertiary colors directly in terms of non-simple ratios of light and dark? ", "There should be no mathematical obstacle to this. ", "Does Aristotle's failure to describe the direct determination of the tertiary colors by non-simple ratios of light 6.2. ", "CHROMATIC RATIOS OF LIGHT AND DARK 139 and dark read in light of the claim that he does make, that the tertiary colors are a mixture of secondary colors, suggest, instead, that he believed that there was no such direct determination? ", "Given the mathematical possibility, that the tertiary colors are not actually determined in this way could be evidence for a kind of material recalcitrance at work in chromatic mixture. ", "Second, a question arises concerning the number of tertiary colors. ", "From the fact that they correspond to non-simple ratios of light and dark it does not follow that for every non-simple ratio of light and dark there exists a tertiary color. ", "So we cannot assume that there are infinitely many. ", "Just as there are finitely many primary colors and finitely many secondary colors, perhaps there are finitely many tertiary colors. ", "Aristotle in the passage, however, declines to directly say. ", "This issue must be settled by appeal to more general considerations. ", "Third, in speaking of the secondary colors as species, is Aristotle allowing for the possibility that different colors might each be members of the same chromatic species the way different individual animals-a pair of hogs, say-may each be members of the same species. ", "This bears on how we are to think of the ordering of the colors. ", "The intermediate secondary colors are ordered between the extremes of light and dark in part because of the similarities and differences they bear to these opposites. ", "However, there are similarities and differences between members of a species. ", "This hog has greater magnitude than that hog, and yet both protest when hungry. ", "By analogy, there would be similarities and differences between colors that are members of the same chromatic species. ", "Perhaps there are discriminable shades of crimson. ", "Each is recognizable as belonging to the relevant chromatic species, crimson, but being discriminable, there are visible differences between them. ", "Indeed, Aristotle gives just such an example. ", "Shades of black and shades of gray are members of the same chromatic species, they are each black, or better yet, dark, but there are visible differences between them. ", "If that is right, then the ordering of the intermediate secondary colors between the extremes of light and dark, while a similarity ordering determined by a decreasing proportion of light, is not a complete similarity ordering. ", "There will be color similarities and differences-the similarities and differences between members of the chromatic species-not captured by that ordering. ", "In modern parlance, the incomplete ordering would be determining color determinables and not determinate colors. (", "On the determinable–determinate distinction see Johnson 1921. ", "For a contemporary defense of the idea that we perceive determinable qualities see Allen 2010; Stazicker 2011.) ", "Fourth, and finally, that there are discriminable shades of color that belong to the same chromatic species bears on the question of cardinality. ", "Is the question whether there are finitely many species of color? ", "Or is it rather whether there are finitely many discriminable shades of color? ", "There could be finitely many chro140 CHAPTER 6. ", "THE GENERATION OF THE HUES matic kinds and infinitely many discriminable shades (especially if we bear in mind that a discriminable shade is only potentially discriminated, in some potential circumstance of perception, not necessarily the actual one). ", "To get a better sense of the mathematical content of Aristotle's theory, let us begin with the simple ratios in terms of which the five intermediate secondary colors are understood. ", "Aristotle first introduces this idea in the context of explaining the juxtaposition model, an account of the generation of the hues that he rejects. ", "In fact, Aristotle introduces two distinct ideas, only one of which remerges in his discussion of chromatic mixture: Such, then, is a possible way of conceiving the existence of a plurality of colours besides the white and black; and we may suppose that many are the result of a ratio; for they may be juxtaposed in the ratio of 3 to 2, or of 3 to 4, or in ratios expressible by other numbers; while some may be juxtaposed according to no numerically expressible ratio, but according to some incommensurable relation of excess or defect; and, accordingly, we may regard all these colours as analogous to concords, and suppose that those involving numerical ratios, like the concords in music, may be those generally regarded as most agreeable; as, for example, purple, crimson, and some few such colours, their fewness being due to the same causes which render the concords few. ", "The other compound colours may be those which are not based on numbers. ", "Or it may be that, while all colours whatever are based on numbers, some are regular in this respect, others irregular; and that the latter, whenever they are not pure, owe this character to a corresponding impurity in their numerical ratios. ", "This then is one way to explain the genesis of intermediate colours. (", "Aristotle, De Sensu iii 439b26–440a6; Beare in Barnes 1984b, 8) The first idea then involves the application of musical intervals to colors. ", "On this idea, the secondary colors are like consonances. ", "Consonant notes blend when played simultaneously and are pleasant to listen to. ", "Just like concords, the secondary colors are more agreeable than the tertiary colors. ", "Consonant notes stand in certain intervals that can be represented by simple numerical ratios. ", "Given the empirical success of ancient theories of acoustics in developing a mathematical account of these intervals, the suggestion is that these theories, or theories of their type, may be extended to other sensible objects, in the present case, color. ", "So some colors are the result of simple numerical ratios that correspond to consonant musical intervals, whereas other colors cannot be expressed as rational numbers. ", "The analogy Aristotle draws between color theory and acoustical theory proved influential. ", "Even Newton accepted the analogy. ", "Newton, like Aristotle, believed that colors have consonances just as pitches do, and he divided the spectrum into seven 6.2. ", "CHROMATIC RATIOS OF LIGHT AND DARK 141 divisions (excluding white and black, pace Aristotle) corresponding to the seven notes of the just diatonic scale (see Shapiro 1994, 619). ", "The second idea is like the first, except that all colors are represented by rational numbers, each are determined by a numerical ratio of light and dark, it is just that some are regular and some are irregular. ", "The colors associated with regular ratios are pure, with irregular ratios impure. ", "Ross (1906, 155-156) makes the plausible suggestion that the impurity of the tertiary colors determined by irregular ratios is a chromatic desaturation. ", "The secondary colors are more saturated than the tertiary colors which are unsaturated to varying degrees. ", "No doubt it is, in part, the increase in saturation that makes the secondary colors more pleasant to behold and so chromatic consonances. ", "This second idea is only entertained in the context of the juxtaposition model. ", "Aristotle probably does not accept it. ", "At any rate, when we come to Aristotle's account of the generation of hues in terms of the mixture of light and dark, he endorses only the first idea: Colours will thus, too be many in number on account of the fact that the ingredients may be combined with one another in a multitude of ratios; some will be based on determinate numerical ratios, while others again will have as their basis a relation of quantitative excess. ", "And all else that was said in reference to the colours, considered as juxtaposed or superposed, may be said of them likewise when regarded as mixed. (", "Aristotle, De Sensu iii 440b18–23; Beare in Barnes 1984b, 10) This is less an account than the beginnings of one. ", "Aristotle never specifies which intermediate secondary color goes with which simple ratio, such as 3 to 2, or 3 to 4. ", "Nor does he explore to what extent ancient acoustical theory may be extended to the colors in the way that he envisions (much to his detriment, see Sorabji 1972). ", "Nor are we ever told how, exactly, the intermediate secondary colors are ordered. ", "Given its candidacy for being included in the extreme chromatic species, white or light, yellow, understood as a distinct intermediary, is the brightest of the secondary colors. ", "But the ordering of the rest of the intermediate secondary colors is left unspecified. ", "This is less a theory, than a research program. ", "Given the empirical success of ancient acoustical theory, the role of ratio or harmony in the respected opinions of the wise, and his own experience gleaned from dialectical engagement with the endoxa, Aristotle most likely felt that there were good reasons to believe that this research program could in fact be carried out. ", "But the De Sensu account is not the result of that program but merely its statement. ", "Let us return to the question of cardinality. ", "Aristotle claims that there are finitely many sensible qualities in an ordered range between opposites. ", "But in what sense does he intend this claim? ", "Is it that there are only finitely many sensible species in the range? ", "Or if distinct sensible qualities may be members of the same 142 CHAPTER 6. ", "THE GENERATION OF THE HUES sensible species (such as gray and black seem to be), is Aristotle claiming, in addition, that sensible species only have finite members? ", "To resolve these issues, we turn to an important if difficult passage from De Sensu vi: For in all classes of things lying between extremes the intermediates must be limited. ", "But contraries are extremes, and every object of senseperception involves contrariety; e.g. in colour, white and black; in savour, sweet and bitter, and in all the other sensibles also the contraries are extremes. ", "Now, that which is continuous is divisible into an infinite number of unequal parts, but into a finite number of equal parts, while that which is not per se continuous is divisible into species which are finite in number. ", "Since then, the several sensible qualities of things are to be reckoned as species, while continuity always subsists in these, we must take account of the difference between the potential and the actual. ", "It is owing to this difference that we do not see its ten-thousandth part in a grain of millet, although sight has embraced the whole grain within its scope; and it is owing to this, too, that the sound contained in a quarter-tone escapes notice, and yet one hears the whole strain, inasmuch as it is a continuum; but the interval between the extreme sounds escapes the ear. ", "So, in the case of other objects of sense, extremely small constituents are unnoticed; because they are only potentially not actually visible, unless when they have been parted from the wholes. ", "So the foot-length too exists potentially in the two-foot length, but actually only when it has been separated from the whole. ", "But increments so small might well, if separated from their totals, be dissolved in their environments, like a drop of sapid moisture poured out into the sea. ", "But even if this were not so still, since the increment of sense-perception is not perceptible in itself, nor capable of separate existence (since it exists only potentially in the more distinctly perceivable whole of senseperception), so neither will it be possible to perceive its correlatively small object when separated in actuality. ", "But yet this is to be considered as perceptible: for it is both potentially so already, and destined to be actually so when it has become part of an aggregate. ", "Thus, therefore, we have shown that some magnitudes and their sensible qualities escape notice, and the reason why they do so, as well as the manner in which they are still perceptible or not perceptible in such cases. ", "Accordingly then, when these are so great as to be perceptible actually, and not merely because they are in the whole, but even apart from it, it follows necessarily that their sensible qualities, whether colours or tastes or sounds, are limited in number.

", "Since color acts upon the eye by acting upon the external medium, the effect on the internal medium should be of the same kind as the effect that color has on the external medium. ", "Aristotle explicitly speaks of admitting light. ", "Colors affect the character of the illuminated medium, so in admitting light, the transparent medium within the eye not only must be actually transparent, due to the illuminating presence and activity of the fiery substance, but it must also come to have a character that at least corresponds to the character of the external illuminated medium. ", "The correspondence need not be identity. ", "As we observed, internal and external media may differ in their degree of transparency, and so dark eyes may be illuminated to a lesser degree than the surrounding air. ", "The light admitted by dark eyes, their interior illumination, will not be as bright as the exterior illumination. ", "Nevertheless, the existence and character of the interior illumination depends upon and derives from the existence and character of the external illumination that immediately acts upon it. ", "This places an important metaphysical constraint on the character of the interior illumination. ", "Whatever effect color has on the external medium, such as the surrounding air, the external medium has a corresponding effect on the internal medium. ", "In chapter 4.3, we reviewed some candidate effects. ", "Given the metaphys166 CHAPTER 7. ", "THE EYE ical constraint, the candidate effects on the internal medium, the illuminated water in the eye's interior, correspond to these. ", "In chapter 4.3, I argued that color could not color external media since doing so would be inconsistent with the way that colors are perceptually available within them-either by being inconsistent with the medium being actually transparent or by being inconsistent with the directionality of the visible. ", "The agent of a change must actually be the way that the patient potentially is. ", "Insofar as the external medium acts upon the internal medium-light is admitted-the external medium is an agent of change, the internal medium the patient. ", "Since the external medium could not be colored, in admitting light, the internal medium, the transparent water within the eye's interior, could not in turn be colored. ", "This result is one of the advantages of the present mode of exposition, focused fundamentally on the nature of the transparent, that begins with color's effect on external transparent media before considering color's mediate effect on internal transparent media. ", "In chapter 4.3, I also rejected Burnyeat's suggestion that the illuminated medium is not genuinely altered but merely undergoes a quasi-alteration when acted upon by color. ", "I argued that quasi-alteration was perhaps too Protagorean to be genuinely of Aristotelian provenance. ", "It was, in any case, undermotivated. ", "Burnyeat's case for quasi-alteration depended upon the thought that the medium could not be materially altered by the colors arrayed in it consistent with the perspective relativity of the perceptual availability of the colors. ", "However, I argued that if color acts upon the illuminated medium by promoting or retarding the activity of the fiery substance illuminating it, then that medium undergoes a material change that is not only consistent with the directionality of the visible, but provides an explanation for it. ", "The being of fire consists in its burning. ", "Burning is an activity. ", "And, as such, it has a direction of influence. ", "That the perceptual availability of a color depends upon the perceiver's point of view is due, in part, to the direction of influence that results from that particular's color altering the activity of the fiery substance. ", "As before, three candidate effects remain: (1) The rendering visible of the transparent-making the transparent internal medium perceptually available (2) The rendering visible of colored particulars arrayed in the transparent external medium-making the colored particulars perceptually available (3) Affecting the fiery substance by affecting the amount of it in the internal medium, the water within the eye, or, if this does not come to the same thing, promoting or retarding its activity to some degree, or otherwise affecting its direction of influence (1) follows from the De Anima (ii 7 418b4–6) definition of the transparent. ", "It might seem odd to claim that the transparent water in the eye's interior is per7.3. ", "INTERIOR ILLUMINATION 167 ceptually available to us, even when illuminated. ", "However, recall, by Aristotle's definition of transparency, the transparent appears to us by the colors of remote external particulars appearing through it. ", "Since when we see the colors of remote external particulars, we see them through the transparent medium in the eye's illuminated interior, we see that medium as well. ", "Of course, ordinarily we do not attend to the transparency of the eye's interior water until it is disrupted, when we see floaters, say. ", "But, in seeing the colors, the internal medium must itself be perceptually available, at least in the manner of transparent things enshrined in the De Anima definition of transparency. (", "2) is not only a consequence of the De Anima definition, but is a commitment of Aristotle's description of the wounded soldier. ", "That the colored particulars arrayed within the transparent external medium are perceptually available within the water in the eye's interior is demonstrated by severing the illuminated interior from the perceptive part of the soul, located at or near heart. ", "When the transparency in the eye's interior is no longer extended within, the passages leading from the eye having been severed by a sword's blow, the colors of remote external particulars are no longer perceptually available. ", "The soldier has been blinded by his wound. (", "3) not only draws upon materials available in both De Anima and De Sensu, but coheres well with the De Sensu project of explaining what each of the sense object must be to produce the sensation in full actuality. ", "Moreover, (3) is directly involved in Aristotle's reinterpretation of Empedocles' lanterns analogy. ", "The eye is like a lantern, not because it emits fire, but because its interior is illuminated. ", "Not only does the potentially transparent water in the eye's interior become actually transparent, but it comes to have a character that at least corresponds to the character of the external illumination. ", "The existence and character of interior illumination depends upon and derives from the existence and character of the external illumination that immediately acts upon it. ", "Specifically, the existence and character of the interior illumination will depend upon the amount, degree of activity, and direction of influence of the fiery substance encountered in the external medium and the internal medium's degree of transparency, the degree to which it is receptive to the illuminating presence and activity of the fiery substance. ", "So understood, (3) is not only consistent with, but explanatory of, (1) and (2). ", "In becoming actually transparent, objects can be seen through that medium. ", "Interior illumination is materially sufficient for the perceptual availability of the colors, even if only materially necessary for their perception. ", "And since the colors are perceptually available, they can appear through the transparent medium within the eye's interior, the transparent medium is itself perceptually available, the transparent internal medium appears in the colors appearing through it.

", "Smith translates the qualification as \"some sort of change of quality\", but as Burnyeat (2002, 36–37) importantly points out, the qualification can also be understood as \"a change of quality of a sort\", that is, as an alteration only in an etiolated sense. ", "In the first line of the passage the claim that perception is a sort of alteration, or alteration of a sort, is offered as a justification for thinking that perception is a way of being moved and acted upon. ", "That justification draws, implicitly, upon Aristotle's physics. ", "In Physica vii 1 and viii 4, Aristotle argues that every case of motion involves being acted upon, and in De Generatione et Corruptione i 6 323a13–24 he argues that alteration always involves being acted upon. ", "The attribution of the claim that perception is some sort of alteration, or alteration of a sort, to previous thinkers is doubtful, however, as it makes essential use of the classificatory scheme of the Categoriae. ", "Here, as is not uncommon, Aristotle is endeavoring to understand the views of his predecessors in his own terms. ", "Aristotle may be over-reading, or having dialectical rather than strictly historical concerns, but, to be fair, the connection with qualitative alteration is not far to seek insofar as previous thinkers maintained, as well, that like is affected only by like.

", "Consider the case of one thing acting upon another thus inducing a change of quality, say, fire heating a pot of cool water. (", "My choice of example, though drawn from De Generatione et Corruptione, is far from innocent-in De Anima ii 12 Aristotle will contrast a plant being warmed with an animal's sensation of heat.) ", "At the start of the process, the agent and patient of the change, the fire and the water, have contrary qualities from the same range of qualities-the fire is hot and the water is cool and each is a quality of temperature.

", "They need not be opposites, qualities at the extreme ends of an ordered range of qualities, they may be intermediate qualities from the same range, so long as they are contraries.

", "So the water was initially unlike the fire that heated it in being cool but became like that fire in becoming hot. ", "In De Generatione et Corruptione Aristotle argues against the like-by-like principle as follows: Moreover, if like can be affected by like, a thing can also be affected by itself; and yet if that were so-if like tended in fact to act qua like- there would be nothing indestructible or immovable, for everything would move itself. (", "Aristotle, De Generatione et Corruptione i 7 323b21–23; Joachim in Barnes 1984b, 23) A variant of this argument occurs at this point in De Anima ii 5 (discussed earlier in chapter 2.1.2): Here arises a problem: why do we not perceive the senses themselves, or why without the stimulation of external objects do they not produce sensation, seeing that they contain in themselves fire, earth, and all the other elements, of which-either in themselves or in respect of their incidental attributes-there is perception? ", "It is clear that what is sensitive is so only potentially, not actually.

", "However, as Polansky (2007, 226–227) observes, the argument, when restricted in this way to perception, accrues new significance. ", "If the sense organ acts upon itself, then the exercise of the capacity it endows its possessor with would at best be a mode of self-consciousness.

", "Perception must be a reactive capacity, if it is to be perception at all, otherwise it would not be a mode of sensitivity to remote external particulars arrayed in the natural environment. ", "However, being a reactive capacity is merely a necessary condition for perception. ", "The objectivity of perceptual content depends not only upon perception only ever acting by reacting to the presence of external particulars but also on the perceiver, or perhaps their perceptual experience, becoming like those external particulars actually are. ", "Sheer receptivity is insufficient for sensory presentation. ", "It requires, as well, the assimilation of the sensory object. ", "Not only does the puzzle about the like-by-like principle accrue new significance in De Anima ii 5, but it is susceptible to a novel solution as well. ", "Nowhere in De Generatione et Corruptione i 7 does Aristotle explicitly appeal to the distinction between the actual and the potential. ", "But that distinction is essential to the present resolution of the puzzle. ", "The lesson of the puzzle about perception raised by the like-by-like principle is that the capacity for sight, the form and substance of the eye, is a kind of potentiality, one that requires an external particular, the object of perception, to act upon the eye in order for that capacity to be exercised in seeing that object. ", "It is like fuel which requires an external fire for it to ignite.

", "Given that Aristotle understands motion in terms of potentiality in Physica, it is natural for him to distinguish the relevant senses of potentiality and then distinguish the motions that correspond to these. ", "In De Anima ii 5 the distinction is explained in terms of knowledge: But we must now distinguish different senses in which things can be said to be potential or actual; at the moment we are speaking as if each of these phrases had only one sense. ", "We can speak of something as a knower either as when we say that man is a knower, meaning that man falls within the class of beings that know or have knowledge, or as when we are speaking of a man who possesses a knowledge of grammar; each of these has a potentiality, but not in the same way: the one because his kind or matter is such and such, the other because he can reflect when he wants to, if nothing external prevents him.

(", "Aristotle, De Anima ii 5 417a22–417b1; Smith in Barnes 1984b, 30) In the passage, Aristotle contrasts someone ignorant of some subject matter but educable with a learned person knowledgeable about that subject matter.

", "They do not, for example, know some particular point of grammar, but it is not beyond their ken, and they can be brought to know it through education.

", "They have mastered the relevant point of grammar and, having mastered it, can be said to know it in the way that the ignorant but educable cannot. ", "And Aristotle maintains that this sense of being a knower is also a kind of potentiality. ", "Specifically, to know something is to have the capacity to apply that knowledge in a reasonable manner given the practical circumstances. ", "Thus to apply the grammatical knowledge is to deploy it in one's speech or writing or to recognize its significance in the speech or writing of others, by recognizing a letter as an alpha, say. ", "In exercising their knowledge, they can be said to know as well but in a different sense from one who possesses this knowledge without exercising it. ", "To possess grammatical knowledge, in the relevant sense, just is to have the potential to exercise that knowledge in a reasonable manner given the practical circumstances. ", "But this is a distinct sense of potentiality than is involved in the ignorant but educable's potentially knowing that point of grammar. ", "In the traditional, post-Aristotelian vocabulary, Aristotle is distinguishing between first and second potentiality and, correspondingly, between first and second actuality (schematically represented in table 8.1). ", "The vocabulary is post-Aristotelian since while Aristotle does speak of first actuality he does not generalize the vocabulary in the obvious way.

", "In exercising that knowledge, in applying it in a reasonable manner given the practical circumstances, this potentiality is realized. ", "This is the second actuality. ", "At the end of the passage, Aristotle draws our attention to a corresponding difference in the two transitions to actuality. ", "The transition from first potentiality to first actuality is a form of qualitative alteration in the way that the transition from second potentiality to second actuality is not. ", "Instead of being a change of quality, the transition to second actuality is described as a transition from an inactive potentiality to its active exercise. ", "Describing learning as qualitative alteration can sound odd to modern ears. ", "In assessing the credibility of this claim we should bear two things in mind. ", "First, for Aristotle, the fundamental explanatory properties-the primary opposites, Hot and Cold, Dry and Wet-are sensible qualities. ", "It should be no surprise, then, that coming to know should be understood by him in terms of qualitative alteration. ", "That may help us, to some degree, understand why Aristotle found this claim more natural than we perhaps do, but moderns may still protest incredulity. ", "However, knowledge, even on a modern conception of it, is a state. ", "In coming to know about some subject matter, a person while initially in a state of ignorance about that subject is no longer ignorant but knowledgeable. ", "But the replacement of one state by another inconsistent with it might fairly be described as a case of alteration. ", "How might these distinctions apply to the case of perception? ", "Seeing is the exercise of an animal's capacity for sight. ", "An animal's capacity for sight is a power or potentiality. ", "It need not be exercised-say, when the animal is asleep or in the dark (at least in the case of seeing color if not the fiery or shining, see chapter 4.2). ", "It is natural, then, to understand second potentiality as the animal's possession of a perceptual capacity and second actuality as its exercise. ", "Indeed, at the end of the passage, Aristotle makes this connection explicitly. ", "It is both the inactive potential for knowledge and sense to their active exercise which is the transition to second actuality (De Anima ii 5 417b1; see also De Anima ii 5 417b19). ", "In which case, the second potentiality of perception, the possession of a perceptual capacity, is also the first actuality (De Anima ii 5 417b17–19). ", "Here, however, we encounter a certain awkwardness. ", "Coming to possess a perceptual capacity just does not seem analogous to learning a point of grammar. ", "Indeed, insofar as animals are animate natural beings with perception-that is what distinguishes them from plants-as soon as an animal comes to be, it is endowed with perceptual capacities. ", "So endowing a natural being with the capacity for perception seems more like generation than alteration. ", "This is substantiated later in the chapter when Aristotle writes: 178 CHAPTER 8. ", "TWO TRANSITIONS TO ACTUALITY In the case of what is to possess sense, the first transition is due to the action of the male parent and takes place before birth so that at birth the living thing is, in respect of sensation, at the stage which corresponds to the possession of knowledge. (", "Aristotle, De Anima ii 5 417b17–19; Smith in Barnes 1984b, 31) There remains, however, an important point of analogy. ", "Recall, Aristotle's curious remark that the ignorant but educable has the capacity for knowledge because of their matter. ", "On the hylomorphic theory, matter is a kind of potentiality, and form is a kind of actuality. ", "As we have seen (chapter 7.1), the form of the eye, its actuality, is its capacity to see. ", "And the matter of the eye-the internal water, the membrane-is the potential to have that capacity. ", "In the epistemic and perceptual cases, then, first potentiality is associated with the potentiality of matter. ", "In the epistemic and perceptual cases, the transition to first actuality involves the actualization of the potentiality of matter. ", "Even if a certain awkwardness remains, there is a sense in which the strength of the analogy does not matter. ", "In the perceptual case, Aristotle's real focus is on the transition to second actuality. ", "It is this which is relevant to the general characterization of perception described at the end of the chapter and the definition of perception given in De Anima ii 12. ", "8.3.2 Destructive and Preservative Change The acquisition of knowledge is an alteration, whereas the application of knowledge is a different sort of transition, from the inactive possession of knowledge to its active exercise. ", "Just as the actual and the potential are said of in many ways, so too is being moved or acted upon: Also the expression 'to be acted upon' has more than one meaning; it may mean either the extinction of one of two contraries by the other, or the maintenance of what is potential by the agency of what is actual and already like what is acted upon, as actual to potential. ", "For what possesses knowledge becomes an actual knower by a transition which is either not an alteration of it at all (being in reality a development into its true self or actuality) or at least an alteration in a quite different sense. (", "Aristotle, De Anima ii 5 417b2–6; Smith in Barnes 1984b, 30) Aristotle distinguishes two ways of being moved or acted upon. ", "The first way is a destruction of something by its contrary. ", "This contrasts with the preservation of that which is potential by something actual that is like it. ", "This later is also described as something's development into its true self, a kind of perfection or realization of its true nature. ", "The distinction between the destructive and preservative ways of being moved and acted upon immediately follows Aristotle's contrast between 8.3. ", "DISTINCTIONS AND REFINEMENTS 179 the transition to first actuality and the transition to second actuality. ", "Plausibly, it is an elaboration of how these transitions differ. ", "Indeed, given that Aristotle understands motion in terms of potentiality in Physica, it is natural for him to first distinguish the relevant senses of potentiality and then distinguish the motions that correspond to these. ", "Recall the transition to first actuality, at least in the epistemic case in which it is introduced, was a kind of qualitative alteration. ", "The motion involved in alteration involves a process whereby a thing's quality is replaced by another from the same range which is its contrary. ", "Thus when the water is heated, it becomes hot and so is no longer cool. ", "When a thing is altered, it becomes other than what it was, at least in the relevant qualitative respect. ", "The motion involved in qualitative alteration, as Aristotle understands it, is thus aptly described as a destruction of something by its contrary. ", "The cool of the water is destroyed and replaced by its contrary, heat. ", "Ignorance is destroyed and replaced by knowledge. ", "It would be inapt, however, to describe the transition to second actuality as a destruction of something by its contrary. ", "When a learned person applies their grammatical knowledge-by recognizing a letter as an alpha, say-they do not lose that knowledge. ", "The learned person does not thereby become ignorant in applying their knowledge in a reasonable manner given the practical circumstances. ", "The application of knowledge does not involve the destruction of that knowledge and its replacement by its contrary, ignorance. ", "Rather, to possess such knowledge is to have the potential to exercise that knowledge in a reasonable manner given the practical circumstances. ", "In exercising that knowledge, this potentiality is realized. ", "There is also a difference in the potentialities involved in these transitions. ", "In the destructive motion of qualitative alteration, the water's potential for being hot is exhausted when it becomes actually hot. ", "However, in exercising knowledge in a given circumstance, the learned person's potential to apply that knowledge is not exhausted in this way, but is rather preserved. ", "There is a further salient difference. ", "In the case of alteration, something becomes unlike the way it was. ", "The water is now hot and so unlike the way it was when it was cool. ", "But in applying their knowledge, the learned person does not become unlike, in epistemic respects, the way they were before they applied that knowledge. ", "The retain their grammatical knowledge in applying it. ", "Finally, the application of knowledge is a kind of perfection. ", "In applying their knowledge in a reasonable manner given the practical circumstances, the learned person realizes their nature as a knower. ", "However, in the case of alteration, it is not water's true nature to be hot and so heating it is not a development into its true nature, it is not a process of perfection. ", "Given these differences, Aristotle concludes that the transition to second actuality is either not an alteration, or an alteration in a different sense. ", "This can be read as echoing the earlier qualification of alteration as applied to sensation, which Smith translates as 180 CHAPTER 8. ", "TWO TRANSITIONS TO ACTUALITY \"a sort of change of quality\". ", "If it is, then Burnyeat is right in suggesting that it is better understood as alteration of a sort, as alteration in an etiolated sense only. ", "Earlier, I mentioned modern reservations about thinking of the acquisition of knowledge as a kind of alteration. ", "Another source of doubt is of more Aristotelian provenance. ", "In straightforward cases of qualitative alteration of the kind discussed in Physica, the potential of the patient is exhausted in its realization. ", "Recall, this is the sense in which the motion of alteration is incomplete. ", "Such motion is the actuality of this potentiality, a potentiality that is exhausted upon its realization at which point the patient is no longer in motion. ", "But is it really the case that a person's potential to be knowledgeable about some subject matter is exhausted when they actually know about that subject matter? ", "As I observed earlier, in learning we have a transition from one state to another that is inconsistent with it, and this may justify speaking of alteration here, at least in a loose sense. ", "But there are differences. ", "Like the acquisition of a habit or virtue, the acquisition of the excellence of knowledge requires repeated trials-not so with the heating of water. ", "Moreover, in the case of the cool water becoming hot, we have one quality being replaced by another from the same range. ", "But ignorance and knowledge, while inconsistent conditions, are not contraries drawn from a common genus. ", "The present worry is perhaps an anticipation of further qualifications that Aristotle makes in De Anima ii 5 417b10–16 (discussed in the next section). ", "The transition to second actuality is either not an alteration or an alteration in a different sense. ", "Aristotle immediately emphasizes this denial: Hence it is wrong to speak of a wise man as being 'altered' when he uses his wisdom, just as it would be absurd to speak of a builder as being altered when he is using his skill in building a house. (", "Aristotle, De Anima ii 5 417b7–9; Smith in Barnes 1984b, 30) A thinker does not cease to be a thinker when they think, just as a builder does not cease to be a builder when they build. ", "Rather, they realize their nature as thinker and builder, respectively. ", "The exercise of the builder's capacity to build is not an alteration. ", "And this remains true even if in order to exercise that capacity the object of the activity is altered. ", "Thus, bricks are arranged. ", "Moreover, the exercise of the capacity to build is not an alteration even if in order to exercise that capacity the builder themself must undergo various alterations. ", "Thus the location of their limbs alters over time, and building induces fatigue in the builder. ", "Even in the more rarefied case of thinking, a thinker in thinking thoughts may become fatigued. ", "The point is usefully elaborated in terms of an example from De Generatione Animalium: This is what we find in the products of art; heat and cold may make the iron soft and hard, but what makes a sword is the movement of the tools 8.3. ", "DISTINCTIONS AND REFINEMENTS 181 employed, this movement containing the principle of the art. ", "For the art is the starting-point and form of the product; only it exists in something else, whereas the movement of nature exists in the product itself, issuing from another nature which has the form in actuality. (", "Aristotle, De Generatione Animalium ii 1 734b37–735a4; Platt in Barnes 1984b, 38) A swordsmith is one who possesses the art of making swords. ", "The swordsmith imposes the form of the sword on the heated iron through motions of their hammer that embody that form. ", "The form of the sword exists prior to the sword in the art or perhaps the soul of the person who possesses that art. ", "This form guides the motions of the swordsmith. ", "The motions of their hammer occur and occur in the way they do because of that form. ", "Through this process, the iron which potentially has the form of a sword takes on that form in actuality and so becomes a sword. ", "As with the thinker and builder, the swordsmith, in exercising their art, realizes their nature as an artisan of that kind. ", "But this requires that they move the object of their activity by undergoing motions themself, by swinging a hammer, say. ", "Suppose these reflections carry over to the case of perception. ", "The exercise of an animal's perceptual capacities, their undergoing a perceptual experience, is not an alteration, or at best an alteration in a different sense. ", "This would remain true even if in order to exercise that capacity, the perceiver must be materially altered. ", "Indeed, as we have seen, they must. ", "Perception is a reactive capacity. ", "The organ of sensation must be acted upon in order to exercise that capacity. ", "In seeing, the perceiver's eyes are filled with light. ", "The eye's interior illumination is necessary to exercise the reactive capacity they endow the perceiver with. ", "While Burnyeat (1992) is right in claiming that coming to perceive is a psychological rather than a material change, he goes too far in insisting that this precludes the perceiver being, at the same time, materially altered.

(", "Aristotle, De Anima ii 5 417b10–16; Smith in Barnes 1984b, 30–31) We have already encountered a reason for this denial. ", "The transition from ignorance to knowledge through teaching and learning is not the replacement of one quality by another from the same range of qualities. ", "Though ignorance and knowledge are inconsistent states of a rational animal they are not contrary qualities from the same genus. ", "Thus the ignorant but educable and the learned person are not generically alike the way they would be if the transition were a genuine case of qualitative alteration. ", "At the end of the passage Aristotle distinguishes two sense of alteration. ", "A change to a thing's privation and a change to a thing's dispositions and nature. ", "The transition from ignorance to knowledge, insofar as these are inconsistent states, can be described as movement to a condition of privation. ", "In learning about some subject matter, a person is deprived of their ignorance. ", "Privative change seems to echo Aristotle's earlier notion of destructive change. ", "The destruction of something by its contrary is a change to a condition of privation, on at least one reasonable understanding of that notion, perhaps not the only one. ", "So when the cool of the water is replaced by heat, the process can be described as a movement to a condition of privation insofar as the water is deprived of its coolness. ", "As the example makes clear, however, the destruction of something by its contrary may mean something more specific than privation. ", "While a change to a condition of privation, it is also the replacement of one quality by another from a common genus. ", "The alternative is more revealing about the sense of Aristotle's denial that learning is an alteration. ", "A change to a thing's disposition and nature can sound like an aspect of preservative change, being a development into its true self. ", "However, the other aspects of preservative change-the preservation as opposed to the exhaustion of the relevant potentiality, and the way the potentiality is like its realization- are not mentioned in this passage. ", "Moreover, if a change to a thing's disposition and nature were identified with preservative change, Aristotle would lose the distinction between the transition to first and second actuality. ", "A change to a thing's disposition and nature must be understood in some other way. ", "How might a change to a thing's disposition and nature be understood in such a way that (1) Aristotle retains the distinction between the transitions to first and second actuality and (2) and explains his denial that learning is an alteration? ", "Ear8.3. ", "DISTINCTIONS AND REFINEMENTS 183 lier, we acknowledged a certain awkwardness in describing the transition to first actuality as a kind of alteration since a natural body acquiring perceptual capacities seems more like a case of generation than alteration. ", "Here, perhaps, Aristotle is acknowledging that the difference is less extreme than it initially appeared. ", "Part of the effect of the male parent in the generation of the animal, and one that Aristotle draws our attention to, is the development of that animal's natural capacities, specifically, their natural capacity for perception. ", "Perhaps a change to a thing's disposition and nature can be understood as the development of that thing's natural capacities. ", "Knowledge is a natural capacity, at least for rational animals. ", "It is also a dispositional state, and like the acquisition of habit and virtue, the acquisition of knowledge through teaching and learning requires repeated application. ", "So understood, the parallel between the transition to first actuality in the epistemic and perceptual cases is reinstated. ", "Each involves the development of a thing's natural capacities. ", "Moreover, this seems distinct both from preservative change characteristic of the transition to second actuality and from qualitative alteration. ", "Whereas a change to a thing's disposition and nature is the development of the thing's natural capacities, preservative change is the exercise of a thing's natural capacities. ", "In this way, Aristotle retains the distinction between the transitions to first and second actuality. ", "Moreover, the development of a thing's natural capacities is distinct from qualitative alteration. ", "As we observed, at least in the perceptual case, the development of an animal's perceptual capacities is better described as generation rather than alteration. ", "And in the epistemic case, whereas the transition to a state of knowledge about some subject matter may be a kind of privation-one state of a knower is replaced by another state inconsistent with it, this is not, however, the destruction of something by its contrary, understood as the replacement of one quality by a contrary quality from a common genus. ", "In the epistemic and perceptual cases, the transition to first actuality involves the development of the animal's natural capacities, and the transition to second actuality involves the exercise of these capacities. ", "Neither are qualitative alterations, strictly speaking, though analogies remain which perhaps justifies talk of alteration in a more expansive sense. ", "Thus the transition to first actuality in the epistemic case was initially described as an alteration no doubt in part because ignorance is replaced with knowledge. ", "But, as I have emphasized, this is not qualitative alteration since ignorance and knowledge are not contrary qualities from a common genus. ", "And in the perceptual case, the transition to second actuality is like qualitative alteration in that it requires an external cause. ", "Perception is essentially a reactive capacity. ", "It only acts by reacting. ", "The sense organ must be acted upon if the perceptual capacity that it endows its possessor with is to be exercised. ", "Only in this way is perception a mode of sensitivity or receptivity. ", "But again, despite the testimony of the endoxa, the exercise of this capacity is not an alteration. ", "The 184 CHAPTER 8. ", "TWO TRANSITIONS TO ACTUALITY transition to second actuality is not incomplete the way that the motion involved in qualitative alteration is. ", "In perceiving the brilliant white of the sun, the perceiver is seeing and has seen. ", "Perceptual activity is complete at every instant, and the transition to second actuality is an instance of preservative change rather than qualitative alteration. ", "8.4 The General Characterization of Perception At the end of the chapter, Aristotle offers a general characterization of perception: As we have said, what has the power of sensation is potentially like what the perceived object is actually; that is, while at the beginning of the process of its being acted upon the two interacting factors are dissimilar, at the end the one acted upon is assimilated to the other and is identical in quality with it. (", "Aristotle, De Anima ii 5 418a3-6; Smith in Barnes 1984b, 31) Earlier, Aristotle distinguishes two sense of perception: We use the word 'perceive' in two ways, for we say that what has the power to hear or see, 'sees' or 'hears', even though it is at the moment asleep, and also that what is actually seeing or hearing, 'sees' or 'hears'. ", "Hence 'sense' too must have two meanings, sense potential, and sense actual. ", "Similarly 'to be a sentient' means either to have a certain power or to manifest a certain activity. (", "Aristotle, De Anima ii 5 417a10–13; Smith in Barnes 1984b, 19–30) Perception is thus either the capacity to perceive or its exercise in perceptual experience. ", "What is being characterized, here, is not the exercise of the capacity but the capacity itself. ", "What has \"the power of sensation\" possesses that power even when asleep when that power remains dormant and so unexercised. ", "So Aristotle is offering a general characterization of perception, understood not as perceptual experience but as the capacity to undergo such experiences. ", "Perception, here, is understood as a power or potentiality. ", "Specifically, perception is the potential to become like the perceived object actually is as the result of that object acting upon the perceiver. ", "As should by now be clear, had this characterization been given at the beginning of the chapter, it would be easy to misunderstand the perceived object acting upon the perceiver as a case of qualitative alteration. ", "After all, cool water in a pot has the potential to be like the fire that heats it. ", "Part of the point of the refinements and qualifications that proceed this characterization is to forestall such misunderstandings. ", "8.4. ", "THE GENERAL CHARACTERIZATION OF PERCEPTION 185 Perception is the potential to become like the perceived object. ", "The emphasis on likeness in Aristotle's general characterization plays an important epistemic role (see Burnyeat 2002, 58). ", "Assimilation, along with the reactive character of our perceptual capacities, is what underwrites his perceptual realism. ", "If perception involves becoming like the perceived object actually is, then it is a genuine mode of awareness. ", "One can only perceptually assimilate what is there to be assimilated. ", "If perceptual experience is a mode of assimilation, then one could not undergo such an experience consistent with a Cartesian demon eliminating the object of that experience. ", "If there is no external object, then there is nothing which the perceiver, or perhaps their experience, has become like. ", "In perceptual experience we simply confront the primary object of the given modality. ", "We cannot be confronted truly or falsely, correctly or incorrectly. ", "We simply confront what is presented to us in sensory conscious and so become like the way it is in actuality. ", "As we shall see in chapter 9, the assimilation of sensible form underwrites a strong form of perceptual realism rejected by the early moderns. ", "Thinkers as diverse as Galileo, Descartes, Hobbes, Locke, and Boyle were united in rejecting this premodern form of realism. ", "Aristotle does not elaborate the sense in which the perceiver, or perhaps their perceptual experience, becomes like the perceived object is in actuality. ", "However, an important clue emerged earlier in the chapter. ", "It involves the way likeness must be understood in preservative change. ", "One way, not the only way, to motivate a literalist interpretation involves a particular understanding of what is required in saying that one thing is like another. ", "On the literalist interpretation, in seeing a colored particular the perceiver's eye takes on that color (Slakey 1961; Sorabji 1974, 2003; Everson 1997). ", "In seeing the brilliant white of the sun, the transparent medium within the eye itself becomes brilliant white. ", "This would follow on a natural understanding of becoming like. ", "On that understanding, if one thing is F and another thing becomes like it in the relevant respect, then it too is actually F. However, given that the potentiality involved in the transition to second actuality is like the actuality that realizes it, Aristotle is working with a broader understanding of likeness here. ", "If the potentiality involved in possessing grammatical knowledge is already like its realization, there is no general requirement that if two things are alike in a certain respect they must actually have the relevant feature. ", "The likeness involved in the general characterization of perception, understood as a sensory capacity, is not the likeness between that potentiality and its actualization, but the way in which the perceiver becomes like the object perceived. ", "Nevertheless, the point is general. ", "In order to sustain his judgment that the second potentiality of grammatical knowledge is like the second actuality that is its realization, Aristotle simply could not adhere to the principle that two things are only alike if they actually share the same feature. ", "It is worth bearing in mind that Aristotle is working with a broader understanding of likeness when interpreting the doctrine of the 186 CHAPTER 8. ", "TWO TRANSITIONS TO ACTUALITY assimilation of sensible form. ", "The point may be elaborated with Aristotle's example of the swordsmith from De Generatione Animalium. ", "In producing the sword, the iron becomes like the form of the sword contained in the soul of the person possessing that art. ", "In the perceptual case, the perceiver assimilates the form of the perceived object. ", "In the production of artifacts, the direction of assimilation is reversed. ", "It is not a person assimilating the form of an external object, but an external object assimilating a form that is in some sense in the person. ", "In the swordsmith's case, the iron assimilates the form contained in soul of the person possessing the relevant art. ", "But there is no actual sword in the smith's soul. ", "So, in perceiving the brilliant white of the sun, the perceiver may become like the sun actually is, but not by becoming brilliant white. ", "Even by the standards of De Anima, De Anima ii 5 is an unusually tortured chapter. ", "Aristotle's evident hesitancy and incessant qualification makes the chapter difficult to read, and there is, quite rightly, substantive disagreement about how exactly all the qualifications hang together (see, inter alia, Burnyeat 2002, Heinaman 2007, and Bowin 2011). ", "What is the significance of Aristotle's hesitancy and incessant qualification? ", "Let me speculate about three potential sources. ", "First, there is not in Greek the vocabulary to mark the distinctions he needs to mark (nor in Persian, nor Egyptian, nor Aramaic, nor in any of the other ancient languages). ", "Aristotle is engaged in conceptual innovation and so must explain, as best he can, his intended meaning in terms that are liable to be misunderstood. ", "Hesitancy and qualification is what one would naturally expect from one engaged in such a project of conceptual innovation. ", "Second, there is a sense in which the hesitation and incessant qualification flows from the puzzling nature of the subject matter. ", "According to the Heraclitean account of perception in the Secret Doctrine of the Theaetetus, perception is the outcome of active and passive forces in conflict. ", "As the Secret Doctrine makes clear, there are active and passive elements in perception that must be carefully disentangled lest we lapse into a kind of Protagorean relativism. ", "If realism about the manifest image of nature is to be sustained, then the interplay of active and passive forces in perception must be carefully understood. ", "But it is easy to be puzzled about how, exactly the active and passive combine in perception. ", "Consider being moved and acted upon in cases of qualitative alteration. ", "Fire acts upon the pot of cool water and thus the water becomes hot. ", "The power to become hot is a passive capacity of the water. ", "Heating is something that the fire does and that the water merely undergoes. ", "Similarly, in the perceptual case, the perceived object must act upon the perceiver, at least if perception is a mode of sensitivity as it must be if perception is so much as possible. ", "But if perceiving were merely a passive capacity, then seeing would not be something that a perceiver does, but rather something done to the perceiver by the object of perception. ", "But seeing is not something done 8.4. ", "THE GENERAL CHARACTERIZATION OF PERCEPTION 187 to the perceiver, even if the perceptual experience by which they see is something they undergo. ", "Seeing is, rather, the exercise of the perceiver's capacity for sight.

(", "Aristotle, De Anima ii 12 424a18–23; Smith in Barnes 1984b, 42–43) Aristotle is explicit that the analogy is meant to hold of perception generally, as opposed to just vision or audition, say.

", "Does he mean the sense organ or the perceptual capacity the sense organ possesses, or at least endows the perceiver with? ", "Given that Aristotle claims that a sense is what possesses this power, it is natural to understand him as having the sense organ in mind. ", "So, for example, it is the eye that possesses the capacity to see, or at least endows their possessor with that capacity. ", "In possessing or endowing the capacity to see, the eye potentially assimilates the color of remote external particulars. ", "Is the assimilation of sensible form a material change that the eye undergoes in seeing, or is it a psychological change, the exercise of sight in seeing? ", "Though Aristotle rejects the answer in the style of Gorgias, an echo of the ingestion model remains in his optical anatomy. ", "The eye in seeing is like a lantern, not because it emits fire from its interior, but because its interior is illuminated. ", "The eye, being transparent, admits the external light within, in the sense in which it can, light being a state, the state of illumination, and not a material body. ", "While a materially sufficient condition for the perceptual availability of a colored particular, it is merely a necessary condition for its perception. ", "The wounded soldier's eyes are filled with light though he does not see since the passages leading within have been severed.

", "THE WAX ANALOGY 191 While denying that perception involves the assimilation of material effluences, Aristotle retains Empedocles' conception of sensory awareness as a mode of assimilation, it is just that we assimilate form without matter.

", "I believe the variation is intentional. ", "Both a stylus and a signet ring are involved in the production of writing. ", "The difference concerns their distinctive discursive roles. ", "The significance of this discursive difference will emerge in sequel.

", "To get a sense of this contrast, first consider how Hume himself appropriates the Platonic analogy: All the perceptions of the human mind revolves themselves into two distinct kinds, which I shall call impressions and ideas. ", "The difference betwixt these consists in the degree of force or liveliness, with which they strike upon the mind, and make their way into thought and consciousness. (", "Hume 1739, Treatise i 1 1 1) Hume begs his reader's indulgence in taking liberty with the use of the terms \"impression\" and \"idea\" (Hume 1739, Treatise i 1 1 n2) though he claims that it is at least a virtue of his regimentation that it \"restore[s] the word, idea, to its original sense, from which Mr. Locke had perverted it, in making it stand for all our perceptions.\" ", "Hume is presumably taking liberty with his use of the term \"perception\", as well.

", "It rather signals Hume's intention to confine himself to what might be described in a later terminology as the phenomenology, the intentional objects of consciousness, in particular, to the few regular principles that govern the persistent change among the perceptions present before the mind. ", "Like Aristotle, Hume is departing from Plato in using the analogy of impressions on wax to describe perceptual experience (and more besides, passions are impressions as well).

", "Hume is still thinking of sensory impressions as the effects produced in the perceiver by external objects acting upon them. ", "Is there an intelligible alternative? ", "How else might talk of impressions be understood? ", "Consider the closely related metaphor of shaping. ", "There is clearly a causal sense of shaping. ", "When the stylus shapes the wax tablet it causes the wax to be modified in a certain way. ", "The wax takes on the shape imposed upon it by the stylus.

", "Earlier we observed that Aristotle varies the Platonic analogy by substituting a signet ring for Plato's stylus. ", "What is the significance of this variation? ", "Both are involved in the production of writing. ", "The difference lies in their distinctive discursive roles. ", "Caston observes that the impression produced by a signet ring is linked to that particular ring and, hence, metonymically at least, to the legitimate possessor of that ring: A signet produces a sealing, an impression that establishes the identity 196 CHAPTER 9. ", "FORM WITHOUT MATTER of its owner and consequently his authority, rights, and prerogatives. ", "When a sealing is placed on a document, especially for legal or official use, it authorizes the claims, obligations, promises, or orders made therein. ", "A sealing thus differs from other impressions in that it purports to originate from a particular signet. (", "Caston, 2005, 302) The impression of a signet ring thus plays a similar role to signatures. ", "Just as a signature is linked to the particular person whose signature it is, the impression sealed upon the wax by a signet ring is linked to the legitimate possessor of that ring. ", "Moreover, signatures, like sealed impressions, carry a certain authority, the authority endowed by their legitimate possessors. ", "Of course, signatures can be forged, as can signet rings, which can also be stolen, but these practices gain there point precisely by the link between a signature and sealed impression, on the one hand, and their legitimate possessors, on the other. ", "Signet rings and styli thus have distinctive discursive roles. ", "The impression made by a stylus is not linked to its legitimate possessor-one scribe may borrow another's stylus-the way an impression sealed by a signet ring is. ", "Taking this feature of the analogy seriously has an important consequence for how sensory impressions are individuated. ", "Just as a forged signature is not my signature, an impression sealed by a forged ring, or by a stolen ring, is not the seal of the ring's legitimate possessor. ", "Impressions are individuated by their legitimate sources. ", "If this feature of the analogy carries over, then perceptions, conceived on the model of sealed impressions, are individuated by their objects which are their source. ", "A perception of Castor and a perception of Pollux are different perceptions, no matter how closely the twins may resemble one another.

", "A forged seal may be a perfect duplicate of a genuine seal but it is not the seal of the ring's legitimate possessor. ", "Castor may be a perfect duplicate of Pollux, but my visual impression of Castor is not an impression of Pollux. ", "Notice that a causal understanding of sensory impressions, as merely the effects of causal shaping, does not have this consequence. ", "If, as Hume maintained, cause and effect are contingently connected, the same effect, the same impression, could have been produced by a different cause. ", "Sensory impressions, understood as the effects of causal shaping, are not individuated by their causes. ", "If sensory impressions are individuated by their objects which are their sources, they cannot be understood as merely the effects of causal shaping. ", "How else might they be understood? ", "If sensory impressions are individuated by their objects, perhaps these objects shape sensory consciousness not causally, or at least not merely. ", "Perhaps in being individuated by their objects, these objects constitutively shape our sensory impressions of them (for contemporary discussion of this suggestion see McDowell 9.2.

", "The medium, in being imperfectly transparent, limits color's power, however. ", "In an imperfectly transparent medium, color has a limited sphere of influence.

", "Moreover, not only is color's power limited but within its limited sphere it is variable as well. ", "Here, the directed influence of the fiery substance, its extent and degree of activity having been acted upon by the color, is impeded by the composition of the imperfectly transparent medium. ", "Just as, in the case of the sun seen through a cloud of smoke, the influence of the sun's radiance is impeded by black particulate matter suspended in the air. ", "And just as in the case of the sun, the impediment to incorporeal activity, a rarefied form of burning, posed by the imperfectly transparent medium affects the appearance of colors seen through it.

", "There is neither the need for, nor the possibility of, the color of a remote particular traveling the spatial gap between that particulars and the perceiver. ", "Qualitative assimilation lacks the spatial presuppositions that makes the material assimilation of remote objects seem problematic. ", "Understanding assimilation, not as it figures in the ingestion model, as a mode of material assimilation, but on the model of qualitative alteration, thus bears on Empedoclean puzzlement in two ways.

", "That is merely a negative claim about sensory presentation, that it lacks a feature that made the sensory presentation of remote objects seem problematic. ", "But importantly, Aristotle, in his definition, is also making a positive claim. ", "In seeing the brilliant white of the sun, the perceiver may take in the color of the sun consistent with its being distant. ", "The sun remains in the heavens even as it shapes the perceiver's experience of it. ", "Talk of taking in may be a phenomenologically apt description of the perceiver's experience of the color of the sun, but what does taking in mean, here, if it is not a material mode of assimilation? ", "Aristotle positive claim provides an answer, and one that is consistent with the object of visual experience remaining remote. ", "Taking in the scene before one is not a mode of material assimilation, it is a mode of qualitative assimilation akin to, but distinct from, the qualitative assimilation involved in qualitative alteration (chapter 8). ", "Perception is like qualitative 9.3. ", "THE RESOLUTION OF EMPEDOCLEAN PUZZLEMENT 213 alteration in that the perceiver must be acted upon to exercise their perceptual capacities and that this exercise involves a mode of qualitative assimilation, but crucial differences remain. ", "The exercise of our perceptual capacities may involve qualitative assimilation, but it is not the destruction of something by its contrary, the replacement of one quality by a contrary from a common genus, but a preservative change. ", "This is a kind of perfection-in exercising their perceptual capacities, the perceiver realizes their nature as a perceiver. ", "And whereas the motion of qualitative alteration is incomplete, the relevant potentiality exhausted in its realization, perceptual activity is complete at every instance, its potentiality preserved. ", "In seeing the brilliant white of the sun, the perceiver both sees and has seen. ", "Moreover, qualitative assimilation in the case of vision does not require the perceiver to become exactly like the way the perceived object is prior to perception. ", "The visual experience of the perceiver may be constitutively shaped by the color of the sun and so like it, in some relevant sense, but not by the perceiver becoming white within. ", "Moreover, qualitative assimilation in the case of vision, if not in the case of alteration, is relative to a point of view. ", "The perceiver takes in the white of the sun by the perceiver, or perhaps their perceptual experience, becoming like the way the sun is actually like, brilliant white-by the sun's brilliant whiteness constitutively shaping their visual consciousness in being presented to their point of view. ", "It is this further positive claim that constitutes Aristotle's resolution of the generalized form of Empedoclean puzzlement. ", "Even if we grant that we can take in what remains external, we can still be puzzled about what talk of taking in, here, means such that we could. ", "Aristotle's definition of perception is a resolution of this residual puzzlement precisely by offering an answer: In seeing we take in the color of the remote external particular by our experience becoming like the color presented to our point of view, by that color, presented in that way, constitutively shaping our visual consciousness. ", "Not only does Aristotle's positive claim provide an answer to what taking in amounts to when we take in the external scene by seeing it, but it also provides the basis of explaining the enduring appeal of talk of taking in or assimilation. ", "In seeing the brilliant white of the sun, we take in the color of that heavenly body by our experience becoming like the sun actually is, by its color constitutively shaping our visual consciousness in being presented to our point of view. ", "In perceiving we become like the perceived object actually is. ", "The objectivity of perception consists in its being a mode of assimilation. ", "If there is nothing that visual experience becomes like, if there is nothing it assimilates to, then it would not be a mode of assimilation and, hence, not a mode of perception. ", "The perceiver's perceptual experience could not be as it is if a Cartesian demon eliminated the perceived object. ", "If perception is a mode of assimilation, then the visual experience that the perceiver undergoes in seeing a particular could not be as it is if that particular differed in visible respects 214 CHAPTER 9. ", "FORM WITHOUT MATTER relative to the perceiver's point of view. ", "What was compelling, all along, about the rhetoric of assimilation was its pretension to objectivity. ", "The Giants were rightly impressed by the reality of what can be handled and offers resistance to touch (Plato, Sophist 246a; see chapters 1.4 and 2.1.2). ", "In understanding taking in as a mode of qualitative assimilation akin to, but distinct from, the qualitative assimilation involved in qualitative alteration, Aristotle provides proof of the pretended objectivity. ", "If the perceiver becomes like the way the perceived object actually is, in the sense that their perceptual experience is constitutively shaped by that object as presented to their point of view, then it is impossible for their experience to be as it is and that object be some way other than it actually is at least in sensible respects. ", "Consider grasping a solid body. ", "In handling that body it offers resistance to touch. ", "Being solid, it retains its shape, a shape that the grasping hand conforms to. ", "The Giants' grasping of rocks and trees is a powerful rhetorical gesture. ", "Grasping something which offers resistance to touch is a phenomenologically vivid and primitive compelling experience of what is external to us. ", "If Boswell is to be believed, Dr Johnson's performance outside of a church in Harwich belongs to the rhetorical tradition inaugurated by the Giants: After we came out of the church, we stood talking for some time together of Bishop Berkeley's ingenious sophistry to prove the non-existence of matter, and that every thing in the universe is merely ideal. ", "I observed, that though we are satisfied his doctrine is not true, it is impossible to refute it. ", "I never shall forget the alacrity with which Johnson answered, striking his foot with mighty force against a large stone, till he rebounded from it,\"I refute it thus.\" ", "This was a stout exemplification of the first truths of Pere Buffier, or the original principles of Reid and Beattie; without admitting which, we can no more argue in metaphysicks, than we can argue in mathematicks without axioms. ", "To me it is inconceivable how Berkeley can be answered by pure reasoning ... (Boswell, 1935, i 471) The reality of external matter was demonstrated in the resistance it offered to Dr Johnson's foot, which rebounded despite its mighty force. ", "It was a demonstration not in the sense of proof, since it is inconceivable how Berkeley can be answered in pure reasoning. ", "Moreover, what was stoutly exemplified was metaphysically axiomatic, a first truth, but proof proceeds from axioms, it does not establish them. ", "Rather Dr Johnson's performance was a demonstration of first truths by showing or exhibiting them (on the character of Johnson's refutation of Berkeley see Patey 1986). ", "The incident reported by Boswell thus dramatizes an important part of the Giant's doctrine-that the palpable is real-even if it fails to dramatize the whole of that doctrine-that only the palpable is real. ", "9.3. ", "THE RESOLUTION OF EMPEDOCLEAN PUZZLEMENT 215 Grasping is an important trope in the rhetoric of objectivity. ", "But notice that even the Giants' grasping of rocks and trees involved a mode of assimilation. ", "Consider the way their hands assimilated to the shape of the rocks and trees they grasped. ", "It is precisely our perceptual experience assimilating to its object that is the source of its objectivity. ", "Grasping may be a paradigm case of sensory presentation, but not because it involves an object being in contact with a sense organ. ", "Rather, it is a paradigm case because the grasping hand assimilates to the object grasped, and thus the objects grasped are presented to us as being independent of our grasping them. ", "But suitably understood, this is a feature of all perceptual experience: For sensation is surely not the sensation of itself, but there is something beyond the sensation, which must be prior to the sensation (Metaphysica Γ 6 1011a1; Ross in Barnes 1984a, 56). ", "For a sensory experience to be perceptual is for it to assimilate the sensible form actually instantiated by its object. ", "This is what underwrites the objectivity of perceptual content. ", "Tactile descriptions of non-tactile modes of sensory awareness are thus emphasizing the objective presentation of their objects. ", "Aristotle's explanation of the objectivity of perception, and his premodern perceptual realism more generally, is lost by the early modern period. ", "Insofar as the early moderns deny that our sensory ideas resemble the objects that elicit them, they deny, as well, that sensory experience is a mode of qualitative assimilation. ", "Insofar as sensory experience is no longer understood as the assimilation of the sensible form actually instantiated by an external particular, the moderns no longer have available to them the Aristotelian explanation of perceptual objectivity. ", "As the modern paradigm reaches the stage of normal science, perceptual presentation is replaced by the simulacrum of \"sheer receptivity\" (Sellars, 1967, 16). ", "The reliable differential responsiveness of sensation usurps the role previously played by sensory presentation. (", "For contemporary discussion of these matters see McDowell 1998 and Kalderon 2011c; for its history see Hamlyn 1961.) ", "According to a form of skepticism found within the phenomenological tradition, modern philosophy is ultimately unsustainable because of its adherence to the metaphysics of presence. ", "If the metaphysics of presence cannot be coherently sustained within modern philosophy, at least with respect to sensory presentation, this is not because of any contradiction or incoherence within the metaphysics of presence, but because modern philosophy abandoned sensory presentation from the beginning. ", "If perception does not resemble its object, then perceived object does not constitutively shape the perceiver's experience, and so that experience could not consist in that object's sensory presentation. ", "Moreover, the idea that colors are, in some suitable sense, secondary qualities depends upon the perceiver's 216 CHAPTER 9. ", "FORM WITHOUT MATTER visual experience not resembling its external cause. ", "The modern conception of colors as secondary qualities only arises in a philosophical context where Aristotle's premodern realism has been abandoned and, with it, sensory presentation itself. ", "Colors only seem secondary when color experience is conceived as a mode of sheer receptivity rather than a mode of sensory presentation. ", "Consider the revulsion Melville expresses for Locke's (1706) metaphysics. ", "In an extended meditation on the whiteness of the Whale as the source of mortal terror, Mellville consider's Locke's view that colors are secondary qualities having just discussed Newton's theory of color: And when we consider that other theory of the natural philosophers, that all other earthly hues-every stately or lovely emblazoning-the sweet tinges of sunset skies and woods; yea, and the gilded velvets of butterflies, and the butterfly cheeks of young girls; all these are but subtile deceits, not actually inherent in substances, but only laid on from without; so that all deified Nature absolutely paints like the harlot, whose allurements cover nothing but the charnel-house within ... (Melville, 1851, ch. ", "42) Experience presents itself as the presentation of particulars whose natures and powers are independent of their being perceived. ", "But if it does, then it is misleading in this regard. ", "The apparent colors of things are but subtile deceits laid on from without for nothing in our phenomenologically vivid color experience resembles its external cause. ", "It is the absence of colors inherent in substances that Melville expresses revulsion for. ", "And he represents this color nihilism as a fall from innocence. ", "We move from the butterfly cheeks of young girls to the painted harlot whose allurements cover nothing but the charnel-house within. ", "I suspect that the \"charnel-house\" is less an expression of misogyny or New England prudery, but Melville further echoing the Lapsarian myth. ", "Death comes East of Eden. ", "The Fall changes our relationship with mortality, and with it, our relationship with ourselves. ", "This absence, and the morbidity of its description, is emotional resonant in the context of the chapter, echoing, the way it does, God's absence. ", "It is because the whiteness of the Whale signifies the absence of God that it inspires mortal terror in those who behold it. ", "Experiencing God's absence is also a kind of fall, and one that changes our relationship with mortality. ", "And it is precisely this that was the source of terror. ", "But if color is absent in the external world, the way the whiteness of the Whale intimates that God may be, then our visual experience could not be as it presents itself as being, as the presentation of the colors that inhere in remote external particulars.

", "Make sure it’s something simple (like “Building a drop-down menu.”) ", "and not something really complex (like “Building a complete shopping cart system”). ", "Feel free to post your suggestions here in the comments, it’ll help to give us a good idea of what people want and what needs better explaining.", "\n\nWe’ve recently started working on the reorganization of the jQuery documentation wiki. ", "Right now it’s quite messy and all over the place. ", "As you can see from the new wiki’s structure, however, is that we’re going for a much more thorough representation of jQuery itself. ", "Within each of these topics we want to include a number of useful “common case” tutorials that will help you to better understand the functions in the jQuery API.", "\n\nSo please: (Taking into account what you see of the new wiki’s structure) What would help you better learn, and use, jQuery?", "\n\n27 thoughts on “Helping you understand jQuery”\n\nPersonally, I don’t think the Wiki is the way to go. ", "Your online API reference is a much better idea and deserves the attention instead.", "\n\nThere was a website (http://home.cogeco.ca/~ve3ll/jstutor0.htm) labeled “The Best JavaScript Example Page I have Seen Yet!!” ", "on digg a few days ago. ", "I personally like this format as it makes Javascript accessible and fun.", "\n\nIMO, Because your API page is simple and terse, it actually makes exploring the JQuery methods fun. ", "If someone wants more detailed information, let them drill down for it. ", "I think you should apply the same idea, but just organize it by feature/goal.", "\n\nAlso, I think you should adopt a system where people can submit their own code examples ala PHP documentation. ", "It wouldn’t show up by default, but you could load it up when a person clicks on a “Show User Submitted Code” link.", "\n\nBTW, I’ve been having a lot of fun with JQuery lately. ", "I’ve written a few extensions lately and I’m looking forward to posting them.", "\n\n@Steve: Just to clarify, the API documentation isn’t going anywhere. ", "It will continue to be built upon, clarified, and explained. ", "The purpose of the documentation contained in the Wiki is to look at jQuery more in the form of a book. ", "Taking the reader through jQuery step-by-step so that they better understand the different aspects of its design.", "\n\nIn addition to that, we’re shooting to “organize by feature/goal” – which is exactly what these tutorials are about. ", "In the end, there should be three things: A fantastic jQuery cookbook (with tons of tutorials and walkthroughs for common situations), a complete guide to jQuery and all of its details (the documentation wiki), and the API method reference.", "\n\nIdeally, the cookbook and API will be seamlessly integrated with the rest of the jQuery guide, to create a single resource that can be used as both a reference and as a great learning guide for new users.", "\n\nyou need better docs for plugins. ", "if i am required to read source code for most plugins i would like to use i could write them myself.", "\nthere are more plugins doing the same thing. ", "i know it’s hard but you should recommend one and write an article on how to use it.", "\n\nHi John,\nYour video on the accordeon menu served me well to integrate into my test site that I use for Jquery experimentation. ", "So additional video tutorials would be nice. ", "Several ideas come to my mind:\n1 I learn the best from seeing Jquery in action so perhaps you can take an example site which is jquery powered and explain the way it uses jquery. ", "In addition to this perhaps a showcase of sites powered by Jquery would be a nice feature to publish on the wikifrontpage. ", "A little showing off here is good. ", "Who wouldn’t like to mention that http://www.mondediplomatique.fr is now running on Jquery? ", "This serves multiple purposes – to attract potential devotees and to show the working of jquery in realworld examples.", "\n\n2 In detail As you can see in my test site I play with the history plugin to inject remote files into the index file. ", "Can you show how to apply effects on these remote files?", "\n\n3 I like to know how to combine Jquery with serverside scripting, particularly RoR. Could you set up a tuturial to built a dynamic site combining both? ", "I understand this is quite broad for a tutorial so maye it could have several episodes.", "\n\nI wanted to throw my 2 cents in. ", "First off, jQuery is my library of choice, and I’m thrilled its direction and the community effort behind it. ", "I have a couple thoughts about how jQuery is presented in general, and I’ll share them in (somewhat) random order below:\n\n1. ", "All the pieces (SVN, trac, blog, site, api, etc) seem to be there, but I really feel like they are spread out all over the place. ", "It’s tough to sit down and grasp exactly what jQuery is and does by just looking at jQuery.com. ", "I love what they have going on at http://www.rubyonrails.com–a beautiful, clear front to a wealth of information.", "\n\n2. ", "I know this post wasn’t about jQuery.com, but I think that this is the key to getting people on board with it. ", "I really have trouble using it especially because of the global navigation on the bottom. ", "I’d wager than a ton of people never make it to those links in the first place. ", "I loved the last iteration of the site when the options were at the top–and it seemed a lot simpler, too.", "\n\n3. ", "Re: documentation, I love the new Wiki. ", "It seems like that could really be a great source of information. ", "I love the idea of having cookbooks, too. ", "I wanted to throw this link in here, the django book: http://www.djangobook.com/en/beta/ (that’s one awesome piece of documentation). ", "Because there are so many people willing to contribute to the documentation, I love the wiki format versus the django book–but I thought that was just such a cool doc site.", "\n\n4. ", "Like I said, all the pieces are there–but they seem to be a little spread out. ", "My personal preference (and again, this isn’t a shot at the amazing effort everyone puts in) would be to streamline jQuery.com, add a little bit of branding and design, and make it an umbrella for the main “pieces”.", "\n\n5. ", "With that said, I realize that jQuery.com already *is* an umbrella :) But I guess it just doesn’t feel like it because there is soooo much going on.", "\n\nJohn, I love the project. ", "I really want to see it go places. ", "Thanks for the opportunity to sound off.", "\n\nJohn, I think it would be valuable to have a place for people to share “cookbook” type code. ", "Good solid code examples like your zebra striping or Jörn’s simple example of adding a global loading indicator for all ajax requests are very useful and proves jQuery’s power. ", "Whenever I post code on the mailing list, someone always responds with a better way to do it (you included). ", "So, I think it would be valuable to have a library of useful cookbook examples for simple everyday stuff (not big and complex problems). ", "This should also probably be moderated or there should at least be a way for people to improve code that’s been submitted. ", "That’s my 2 cents.", "\n\n@Steve O: The web site is definitely being worked on. ", "I’m going to have another post on this soon (but there’s a 5 man team working on it! ", "don’t worry!)", "\n\n@Rich: That’s exactly what I’m looking for! ", "Do you have any ideas as what would make for some good easy tutorials/screencasts? ", "This way we can crank a couple out every week, keeping everyone up to date. (", "I mean, I have a couple planned right now – but I’m just curious as to what interests everyone else.)", "\n\nFWIW, I’d like to see some screencast tutorials for some of the plugins out there, especially the interface stuff. ", "Another thing that would be interesting would be some sort of tutorial on the core Ajax stuff; I realize it takes a bit of doing because there has to be some sort of back end (PHP or whatever), but the API to the Ajax stuff has been in flux a bit, so it would be nice to see some walkthroughs.", "\n\nI’ve actually gotten Ajax stuff to work before, I’m just curious to see if I’m using it in the “right” or most efficient way.", "\n\nIn terms of jQuery what annoyed me the most was that I couldn’t find any _offline_ documentation. ", "If I have overseen it, then I am to blame, but one of the really cool thing about JavaScript is that it does not need http (unless you do some Ajax stuff) and I can work on it offline.", "\n\nSo it’d be good if you could offer the docs in a printable and downloadable format. ", "I know this brings up the issue of documentation getting out of date, but I am sure that it would help a LOT of people.", "\n\nI agree with Giel(#10). ", "More on chainability would be great for those of us who just aren’t sure we’re doing things the right/best way.", "\n\nI also agree with Steve O(#5). ", "Simplicity of jQuery.com is key to it’s mainstream success. ", "jQuery itself is simpler and just as powerful as other libraries and I think the site needs to reflect that simplicity, power and depth.", "\n\nAnd lastly I second Patrick’s comments(#8). ", "Ajax is all the rage now but we need clear, concise tutorials on how to take full advantage of it in jQuery while also showing how to use it responsibly. ", "And it would be pretty darn cool to show the server-side portion of the Ajax too. ", "And when doing a tutorial do it from beginning to end and give live examples for dissection. ", "I think doing short fragments of tutorials makes it more confusing.", "\n\nI’m glad your gonna pull all the loose ends and creating a nice tight resource for jQuery. ", "Can’t wait to see it done.", "\n\nAs someone who is very new to website creating and rapidly having to learn as I go, I rely on all the documentation/tutorials/howto’s I can find. ", "I’ve been very impressed/relieved by the relative ease of learning jQuery, particularly due the excellent API docs and some good tutorials (the 15daysofjquery.com has been v. good).", "\n\nI’d like to see:\nCross referencing of tutorials/more examples in the API docs (as Shawn mentions)\n\nMore tutorials on the AJAX functions, especially with ref to the server-side (as mentioned in a few comments above).", "\n\nVideo tutorials are very useful.", "\n\nBetter plugin documentation – generally is good on the specific plugin’s website, but would be great to have it on the wiki.", "\n\nLooking forward to even better documentation, and I second Josh’s comments to pulling loose ends together and creating a tight resource.", "\n\nHi John,\nI’ve written you an email, but Im sure you’re pretty swamped, so I will try to re-iterate some of the stuff I wrote, here. ", "I also wrote a blog post on Prototype vs. jQuery, and some of the issues I’ve been running into, which you can read here:http://www.alterform.com/news/prototype-vs-jquery (the first half is praise, the second is criticism or rather my thoughts on things that caused confusion and IMHO could be improved).", "\n\nI will continue to hound this, and if I honestly don’t hear a response soon, I will go ahead and take the lead, but there needs to be jQuery forums.", "\n\nI’m sorry to all of you mailing list addicts who love mailing lists, but honestly, it’s a little early nineties to the rest of the world. ", "There need to be forums, and again, I will donate the money for a vBulletin license (I say vBulletin, because I like that one the best, but almost anything will do at this point).", "\n\nAnd no, Nabble doesn’t cut it for me. ", "I need a forum, a “real” community where ideas are logically consolidated.", "\n\nI’m not trying to be anal, but honestly, forums are by far the EASIEST way to consolidate information easily in a way that promotes interaction.", "\n\nWhy do I think a forum is absolutely necessary?", "\nBecause I have a TON of questions that I am positive have been asked before on the mailing list. ", "And as far as I know, Nabble doesn’t allow sticky’s, or FAQ posts, or threaded answers on one single page (rather you have to click a link to read each one).", "\nIf managed right, the forums could be the single greatest resource for jQuery next to the API docs and Yehuda’s Visual jQuery.", "\n\nLastly, this is probably completely unasked for, but jQuery needs a massive facelift. ", "No offense to any one who’s worked on it, but the design really does not foster feelings of web 2.0 sexiness. ", "It looks rather old school, and not in a “New Wave” sort of way.", "\n\njQuery is a new way of creating Javascript that finally brings power to designers, and it should look as sexy as it is to the rest of us.", "\n\nI would be more than happy to help in any way I can, but there may already be too many chefs in the kitchen, so to speak.", "\n\nThe more I think about it, the more I realize that the best way I learn is by seeing real-world, well-commented, working examples of common things. ", "Cookbook stuff. ", "Like “How do I save a form via Ajax and hide the form after the save, show a spinner, and flash an “OK” message when I’m done?” ", "Or… how do I make a dropdown menu? ", "Or what’s the best way to handle XYZ. ", "That’s why I love the wiki idea, because a cookbook can fit very well into that, and anyone can edit it.", "\n\n– a star ranking tutorial that updates the amount of star votes on the backend via ajax. ", "I’ve seen these all over and use them but havent seen a jquery one.", "\n\n– when a user pushes the back button on a browser, preserving previous states of elements changed via DOM manipulation (jquery) — for example if a user opens a div on page A then moves to the page B, then clicks the back button to go back to page A – the div is then closed again (ugh I think thats the experience I was noticing the other day … it was a bit of an annoyance)\n\n– more tutorials on accessing DOM elements via xpath\n\n– in-place editing example\n\n– counting words types into a text box example\n\n– example of an event that fires an AJAX request and the response then kicks open a modal dialoge box for the users to respond and based on the response another event is triggers (reads a lot more difficult than it is I think)\n\n– maybe more plugin example…just like .net has “controls” maybe we could see more of a jquery controls idea which I guess is the plugin.", "\n\nMost tutorials are limited by the fact they generally only illustrate one way of doing something. ", "I’d like to see a selector tutorial that demonstrated the numerous ways to select the same (or similar) pattern of elements in a given chunk of HTML. ", "Perhaps with a few pointers to which might be the most appropriate in given circumstances.", "\n\nLike others said above, I’d like to see more tutorials for plugins. ", "I’m talking step by step starting-at-the-basics tutorials, as opposed to “here’s a giant test page that demonstrates every aspect of this plugin, and you need to then figure out what little pieces you need”. ", "Specifically I’ve been having problems figuring out the form plugin. ", "For those of us who learn by following basic tutorials and then building on piece by piece, things like that would be great.", "\n\nAnother idea, and this comes from your mailing list, is a tutorials for adding dom elements (ex A TR or DIV, whatever) to a grid like structure.", "\n\nSo, for example, if you have a basic TODO list application. ", "Initially you could have one row, and a “add another” beneath it. ", "Clicking the “add another” insert a structure with the input fields, with a naming convention that will make it simple to iterate through the results when posted.", "\n\nThis cat can be skinned a hundred ways, but I figured you guys would know best :P\n\nI will second Ollie’s request for a comprehensive selector tutorial. ", "When I was trying to grok this it seemed like all the API examples were using $(“p”) or similar, which doesn’t really demonstrate the specificity that you need to do real work.", "\n\nI see many examples and tutorials that show brief snippets of code, but for the beginner trying to figure out “where everything goes” the small 2 or 3 lines of code wont help them. ", "Maybe a “full code” version of each tutorial would be in order.", "\n\nThere are few things that can help new people dive into the library and will help them to write better scripts:\n– When you were designing the library you kept in mind the way each API methods could be useful in development. ", "In this case would be great to have comments from you (or from somebody from the team) on the way what is particular function could be used on best way. ", "For example we can make AJAX request in JQ a many ways (.get – .post – .load – .ajax) – but seems like every method is designed for some specific purposes. ", "For newbies like me would be great to have written somewhere a list of CASES and short EXAMPLES like: to retrieve hash or table data of medium size (like schedule of something or list of names with addresses) is good to use function(****); for hevy request use ****; for extreamly critical requests with post-processing use *****; for continuous retriving JSON use ***.", "\n– could be great to have some advises (or links to external sites) on the suitable way of writing javascript with JQuery. ", "It is so the documentation on the library itself but more on the WAYS of writing the code.", "\n– also could be great to have a comfortable way to read discussion list: all links in RSS open jquery.com/discuss…. ", "where I can’t follow the discussion. ", "But in http://www.nabble.com/JQuery-f15494.html forum I can also check the whole tread of discussion – it is more comfortable!" ]

", "It took me a few months to become open to talking about Pudding and autism to our friends, but I have no regrets that I did.", "\n\nBought from our Wish List\n\nAlmost every time we speak to a teacher, therapist, or fellow parent, we learn about some new thing that our kid needs. ", "Therapy equipment is expensive, and our kids are still kids too. ", "They like toys, a lot. ", "Because Pudding likes extra stimulation, we use a lot of new things to keep her interested and engaged. ", "Friends have bought things like the sit ‘n’ spin and bead toys for sensory input for birthdays and Christmas.

", "I never get a chance to write all my overdue thank you cards.", "\n\nDo it from a distance\n\nAdmittedly friendships are harder to maintain from a distance. ", "But special needs parenting can be isolating, and any way you find to show a friend you are will mean more than we can express.

", "Even after a few IEP meetings, Spectrummy Daddy was unable to leave work, and I was intimidated by the number of people in the room for Cubby’s IEP eligibility meeting. ", "Even if you don’t know anything about what is being discussed, your presence would be a great source of support. ", "Alternatively, taking care of the child or sibling would mean one less worry for the parents. ", "If you can spare a couple of hours, it would make a huge difference to the stress of the day.", "\n\nSiblings\n\nRemember the siblings. ", "Often we have to prioritize the child with the most demands, and the other one gets overlooked and forgotten. ", "Be sure to focus on the sibling so that they don’t learn that the only way to get attention is by imitating the behaviors of their brother or sister.", "\n\nFood\n\nMany kids on the spectrum have problems with food and dining out. ", "Some are very sensitive to textures and smells, meaning that only a few foods are tolerable for them. ", "Many children can’t handle the noise and activity of restaurants and food courts. ", "Still others are only comfortable in very familiar environments. ", "And then there are those with food allergies or intolerances who need to eat a very restricted diet. ", "If you are the parent dealing with the food issues, I promise that it soon gets unbearable. ", "If the family are willing and able to get to a specific place to eat, consider taking them out for a meal, or buying them a gift certificate for a meal there. ", "If not, find out about their list of okay foods, and prepare a meal. ", "Even one meal less to worry about would be a godsend, and you might even develop a taste for extreme cooking. ", "Not that I have.", "\n\n…\n\nThat was long! ", "Please let me know in the comments any ways your friends have helped you…or ways you’d like them to help.", "\n\nYou know it wasn't a good day when this is the best photo I took of the whole experience.", "\n\nFriday was Pudding’s school field trip to the pumpkin patch. ", "For those who aren’t familiar, a pumpkin patch is where a farm dedicates itself to Halloween and becomes a huge playground with hay rides (being pulled on a tractor), corn mazes, pony rides etc. ", "For me, a big way of alleviating homesickness is by indulging in experiences that are unique to the place I’m living in. ", "We went to one last year, and she had a great time. ", "It was sensory heaven for my little seeker, and she got to ride a pony for the first time. ", "Back then we were still learning a lot about her needs and the way she reacted to certain experiences, so it was nice to put a tick in the “likes pumpkin patches” box.", "\n\nSadly, the field trip went less well. ", "Right before we set off, Cubby fell down the steps outside our house and cut his face. ", "We arrived before the school bus got there, and she skipped about in delight from attraction to attraction. ", "Of course, Cubby wanted to do the same, and without a second adult, it became a not-so-fun game of kid-herding. ", "We had the first meltdown when she didn’t want to leave something to find her classmates. ", "I think the real problem was that she was perplexed by the mix of people from school and home. ", "As soon as she saw the aides, she hid behind me and refused to speak. ", "Her teacher took her away, spent some time calming her down, and then had one-on-one time with her. ", "Unfortunately, this was a small pumpkin patch, so when I took Cubby to see the animals, she saw us and got upset all over again. ", "We joined back up, but she continued to be miserable unless left to do her own thing. ", "Her own thing was to wander to the exit, so that became the end of doing her own thing for that day.", "\n\nLesson learned- I won’t attend any more field trips for the time being. ", "She would have had a much better time without me there, much as I don’t like to admit it. ", "I really don’t like to admit it.", "\n\nAt least we got stickers!", "\n\n__________\n\nI did keep expectations low in the afternoon. ", "We had a play date with her friend E., and hearing that the Disney Store was having a Halloween dress rehearsal, we decided to let the girls dress up in their princess dresses. ", "I wasn’t sure what to expect, so really I should have anticipated an overwhelming and unstructured frenzy of sensory overload. ", "Pudding couldn’t do any of the games, and kept pulling out of the throng of kids to touch all the shiny things that Disney has to offer a princess-obsessed girl. ", "I think we can safely say we won’t be trying that again, although I did get the phone number to see if they’d consider doing a sensory-friendly or special needs event some time.", "\n\n_________\n\nI had great expectations for Friday, and they weren’t met, but I’m okay with that. ", "There are some things she just isn’t ready for yet, but I wouldn’t have known that without trying. ", "I continue to set my expectations higher for tomorrow than yesterday. ", "If we don’t get there today, we adapt, we accommodate, but we keep trying. ", "One day it will happen. ", "Something else happened in between these two events on Friday which reminded me that Pudding has a confidence in herself that I can only aspire to, and whatever she expects for herself, she’ll get.", "\n\nI’d tell you about it now, but I’d rather leave you with great expectations for tomorrow." ]

[ "Enslaved: Odyssey to the West\n\nEnslaved: Odyssey to the West is an action-adventure video game developed by Ninja Theory and published by Namco Bandai Games. ", "Announced in 2009 as Enslaved, it was released on PlayStation 3 and Xbox 360 in October 2010. ", "As a loose adaptation of the novel Journey to the West, the game is set 150 years in a future post-apocalyptic world following a global war. ", "Only remnants of humanity survive, along with the still active war machines left over from the conflict. ", "The game's story follows Monkey who is forced to escort Trip home safely after they survive a ship crash. ", "Players play as Monkey, who must combat enemies using his staff from a third-person perspective, engage in different platforming challenges and solve puzzles.", "\n\nInitially pitched as a CGI film, the game's development began after the team's had halted the development of a sequel to Heavenly Sword. ", "Life After People inspired the game's setting, while the video game Ico inspired the dynamics between the two protagonists. ", "Alex Garland was invited to write the game's story, but he became involved in the game's design to ensure the game was consistent throughout. ", "Andy Serkis and Lindsey Shaw provided performance capture for the game, and Nitin Sawhney composed the game's soundtrack. ", "Ninja Theory used the Unreal Engine 3 game engine to power Enslaved.", "\n\nThe game received generally positive reviews. ", "Critics praised its graphics, world design, Serkis' performance and Garland's script, though the game drew criticisms for its gameplay and technical shortcomings. ", "The game was a commercial failure. ", "Sales failed to meet Namco Bandai's expectations. ", "A single-player downloadable content, titled Pigsy's Perfect 10, was released in November 2010. ", "A complete version, featuring all downloadable content, was released for Microsoft Windows and PlayStation 3 on 25 October 2013. ", "A sequel was planned but later canceled due to the game's financial underperformance.", "\n\nGameplay\n\nThe player takes the role of \"Monkey\" in a third-person perspective, using a variety of combat moves and platforming skills to overcome obstacles. ", "In combat, Monkey uses a staff that doubles as a close-combat and long-range projectile weapon. ", "The staff has two types of long-range ammunition in the form of power cylinders: orange cylinders used for blast damage and blue cylinders used for stunning foes. ", "Monkey can also remain stationary and charge his staff to use the same stun attack. ", "In the game, players encounter numerous mechs as enemies. ", "Certain mechs can be used as weapons. ", "Monkey can perform a finishing move on them when they are low on health, such as tearing the gun off a turret or throwing an explosive foe at other combat mechs. ", "Monkey's other abilities include his force shield that can block a certain amount of damage before requiring a recharge, and the \"Cloud\" device that manifests as a hover board that can be used to glide across water or land at great speeds. ", "When enemies are defeated, they drop tech orbs that can be used to upgrade Monkey's abilities. ", "They allow the player to learn new moves and abilities for combat and devices, increase overall health and shields and the damage that can be inflicted on enemies. ", "Orbs can be found littered across levels, sometimes hidden out of sight, requiring extra exploration at times. ", "Another type of collectible players can amass is masks, which are also scattered across different levels.", "\n\nDuring the game Tripitaka, or \"Trip\", who must be escorted and protected as they travel, accompanies Monkey. ", "He has a device attached to his head linked to Trip. ", "This device, called a slave headband in the game, requires Monkey to keep Trip alive. ", "Should she die he will as well. ", "In some instances just going too far away from her can result in the same fate. ", "Trip can help Monkey overcome obstacles at times by performing certain actions involving her technical skills like hacking into a computer. ", "Players can command Trip to use her different skills. ", "For instance, she can scan the surrounding area revealing hazards such as land mines or mechs on standby, and project a temporary hologram as a decoy to draw the enemy's attention away from Monkey. ", "Players can also order Trip to hide behind covers or regroup with Monkey. ", "Having no combat ability of her own, Trip is vulnerable in instances where she is attacked by enemies. ", "Her only defense is an EMP blast, which she can use to temporarily stun enemies threatening her.", "\n\nOther than combat, the gameplay focuses heavily on platforming where Monkey can scale and leap across the ruins throughout the game. ", "Some areas and platforms will collapse shortly after use, requiring faster scaling before Monkey potentially falls to his death. ", "Trip plays a part in the platforming sections of the gameplay, making some sections of platforming akin to puzzle-styled forms of gameplay. ", "In other instances where Monkey can make jumps/climbs, Trip needs to be thrown to the other side or ride on his back. ", "In some sections of the game Monkey and Trip are separated so the player cannot use her abilities.", "\n\nPlot\nEnslaved is set 150 years in the future after a global war has ravaged the Earth, destroying most of the human race and leaving the world plagued by robots, known as \"mechs\", left over from the war. ", "Mechs still follow their programming and seek to eradicate hostiles, now surviving humans.", "\n\nThe game opens with the main character, Monkey (Andy Serkis), awakening in a containment cell aboard a slave ship. ", "He escapes and accidentally causes the vessel to crash. ", "He reaches Trip (Lindsey Shaw) leaving the ship using an escape pod, but she ejects the pod without allowing him to enter. ", "When Monkey regains consciousness after landing, he discovers Trip has placed a slave headband on him, which forces him to follow her orders; a dead man's switch will kill him if she dies. ", "Trip explains she wants to return to her village, and she needs his help to get there. ", "Monkey is angry but has no other choice. ", "As they travel across New York City, glitches in the headband expose Monkey to visions of what appears to be life before the war. ", "When they reach Trip's village, however, the place is deserted and overrun with mechs. ", "After clearing the village of them, Monkey and Trip discover Trip's father is dead and no other villagers can be found. ", "Assuming everyone is dead, Trip refuses to remove Monkey's headband, explaining her intent to find and kill the person responsible.", "\n\nTrip takes Monkey to meet a friend of her father's named Pigsy (Richard Ridings), who she believes can help them. ", "Pigsy explains that a nearby mech base has the Leviathan, an enormous and incredibly powerful giant mech. ", "The three infiltrate the base, commandeer Leviathan, and steer it to the mysterious Pyramid, where the slaves are being held. ", "Along the way, Trip apologises to Monkey for breaking their deal and deactivates the headband, but Monkey tells her to turn it back on, hinting they have developed a romantic relationship.", "\n\nWhen the Leviathan reaches Pyramid, they are confronted with several mechs. ", "The Leviathan's main cannon fends them off for a while, but one eventually climbs aboard and tears the cannon off, forcing Monkey to destroy the mech himself. ", "With the Leviathan now defenseless and surrounded, Pigsy announces that the only way for them to destroy the opposing mechs is for him to overload the engines. ", "This would blow up the Leviathan and kill Pigsy in the process. ", "Trip frantically tries to convince him not to, but Pigsy demands that Monkey take her away from the blast radius. ", "Monkey and Trip get away just in time to watch the Leviathan explode, destroying all of Pyramid's mechs with it.", "\n\nIn the epilogue, Monkey and Trip enter Pyramid and discover the slaves are under the control of a single individual. ", "The man introduces himself as Pyramid (Andy Serkis) and explains that he lived before the war, and that he offers the slaves solace from the cruel world by sharing with them his memories of a happier era. ", "He believes he is saving them and pleads with Monkey and Trip not to take away what he has given them. ", "Monkey recognises the memories as the visions he has been seeing with the headband on. ", "Pyramid shows Monkey what he has giving the slaves through a mask. ", "Monkey becomes enthralled with the images, but Trip violently disconnects and kills Pyramid, shutting down the system and freeing the slaves. ", "The scene ends with Trip asking Monkey if she did the right thing, leaving those in the pyramid and their future unknown.", "\n\nPigsy's Perfect 10\nSet prior to the events of Enslaved, Pigsy lives a solitary life in the scrap yard with his only companion, a small flying robot named \"Truffles\" who helps him scout scraps and provides advice in combat. ", "Because of his loneliness, Pigsy decides to build himself a friend. ", "This will require three key components that he and Truffles must find in the scrap yard populated by mechs. ", "While Truffles helps throughout his search, Pigsy seems unappreciative and prioritises his new creation. ", "As Pigsy retrieves the last component, Truffles is damaged and shuts down in the process. ", "With his new friend nearly complete, Pigsy learns what his creation actually needs is a \"heart\" and inserts Truffles inside. ", "When activated, however, his creation runs amok before being gathered up by a salvaging mech. ", "Pigsy gives chase and fights his way into the main scrap collector. ", "When he finally retrieves Truffles and escapes, Pigsy realises Truffles was his real friend the entire time. ", "Being greatly damaged, however, Truffles shuts down permanently. ", "Pigsy realises too late he took his only friend for granted and vows not to make the same mistake again.", "\n\nDevelopment\nIn August 2009, Namco Bandai announced they would be collaborating with Ninja Theory on a new video game project. ", "The game, initially titled Enslaved, was announced in September 2010 for release on the Xbox 360 and PlayStation 3. ", "Cambridge-based developer Ninja Theory developed the game. ", "Their previous project was the PlayStation 3 exclusive game Heavenly Sword. ", "Tameem Antoniades acted as the game's director, actor Andy Serkis provided motion capture for the title, film director and producer Alex Garland served as the game's writer and designer, and Nitin Sawhney composed the game's score. ", "Using only two-thirds of the budget of Heavenly Sword, the game's development was completed on 3 September 2010, and the game's publisher confirmed it had been declared gold, indicating it was being prepared for duplication and release.", "\n\nOrigin\n\nAfter completing Heavenly Sword, Ninja Theory intended to develop a sequel but contractual terms with Sony Computer Entertainment forced them to halt the game's production. ", "The studio decided to leave the title and all the technologies built for it to Sony and seek external funding from another publisher for their next project. ", "This would eventually become Enslaved: Odyssey to the West, powered by Epic Games' Unreal Engine. ", "Initially, Ninja Theory pitched the game to several Hollywood studios as a CGI film, but they were not interested in backing the project. ", "The company dedicated three months to creating promotional materials to convince publishers to sign the game. ", "A number of publishers were shown a detailed design document and a two-minute CGI trailer and the team received enthusiastic responses from them. ", "Initially, they signed a deal with Green Screen, but the firm dissolved a month later. ", "Namco Bandai Games later agreed to publish the game.", "\n\nMike Ball, CTO of Ninja Theory, revealed that the initial idea for the game came from Heavenly Sword, in particular, the relationship between the protagonist Nariko and her companion Kai. ", "This relationship resonated with players, and the team wanted to repeat their success with a set of easily recognisable characters. ", "During Heavenly Swords development, Antoniades researched the wuxia genre and read the novel Journey to the West. ", "He found the novel \"epic\" and compared it favourably to The Lord of the Rings. ", "However, Enslaved is only a loose adaptation of the novel. ", "The team decided to shift away from the wuxia theme to science fiction as it was a genre many staff on the development team wanted to explore. ", "As a result, mechs replaced demons, and technology replaced magic. ", "Initially, the game was set in a foreign world. ", "The animations created by Hayao Miyazaki, whose works often integrate nature with steampunk, inspired the team. ", "However, after watching Life After People, the team decided to set the game on Earth, one that was peaceful as nature reclaimed it after humanity's disappearance. ", "A lot of colour, in particular red, was injected into the game's world to reflect this.", "\n\nWriting\nAntoniades wrote the game's early drafts. ", "Serkis was involved in the development of Enslaved from the beginning; Garland became involved six months later. ", "Garland wrote the game's script and designed the cutscenes to ensure the transition between cutscene and gameplay was smooth. ", "Garland agreed to collaborate with Ninja Theory as he was actively looking for a way to become involved in a video game production. ", "The script itself was initially developed separately for a time, and then the gameplay developers joined to \"mesh\" both the story and gameplay. ", "To achieve this a cinematologist was employed to teach editing, camera and film language techniques. ", "These techniques and the use of music were used to make coherent transitions between cutscenes and gameplay.", "\n\nOne of the more important aspects of the script was the characterisation and interaction. ", "The 2001 PlayStation 2 game Ico inspired the characters' relationships. ", "Chief of development Nina Kristensen described protagonists Monkey and Trip as opposites at first whose relationship evolves as they learn to rely on each other in the hostile setting. ", "Serkis helped create the game's characters. ", "Trip's design went through several iterations. ", "She was designed initially to look like a queen and have a pale appearance, so she would look \"gothic\". ", "Tank Girl and Kai from Heavenly Sword inspired the second iteration of her character. ", "She wore a costume that features the face of a character and had tattoos, which the team felt gave the character more personality and attitude. ", "They tried to apply blue paint to Trip's hair, but found it unsuitable as it made her \"too science fiction and punk\". ", "The initial design was deemed too \"aggressive\", so the team modified her design to make her look more delicate and fragile. ", "Monkey has several design features. ", "He wears a face paint, a reference to his counterpart in the Journey to the West novel, and a reflection of the character's tribal nature. ", "Scars were added to his face to increase his sex appeal, while a cloth sash was used to replace Monkey's tail. ", "According to Serkis, Monkey behaved like a \"gruff hobo\" in the game as opposed to being mischievous like he is in the novel. ", "Monkey's hair was once designed as white, inspired by a picture of an albino gorilla.", "\n\nAccording to Antoniades, Garland's initial script was very simple, and the dialogue was \"reductive\". ", "This was part of Garland's intention to reduce the use of story exposition in favour of creating more drama in the script. ", "The actors' body language and vocal cues delivered more of the game's information and plot than the direct use of cutscenes. ", "Initial scripts featured two hours of the cutscene, but it was drastically cut and reduced to only one hour and 10 minutes. ", "To facilitate this style of storytelling, Garland suggested that camera control be taken away from players during certain moments of the game, so they will be introduced to and become aware of the game's environments, which further help to clarify the game's story. ", "This led to an internal debate within the company, with other gameplay designers fearing it would break the gameplay flow. ", "This feature was kept in the game. ", "Antoniades said in hindsight that such techniques \"helped keep things exciting\".", "\n\nDesign\nNinja Theory developed the gameplay to include more variety than their last projects, with the introduction of platforming sessions and puzzles. ", "Players use different approaches to combat, such as stealth, to avoid combat altogether and use Trip's abilities to their advantage. ", "According to Antoniades, the design choice behind this was to make portions of the gameplay more tactical, being at times \"a puzzle game in disguise\" outside the actual puzzle portions of gameplay. ", "The combat itself had fewer combination-style attacks than most combat-heavy action games. ", "It was more accessible and stream-lined while including the different abilities, equipment, enemy types, and scenarios requiring thought so as not to become too easy. ", "Trip's involvement could not make her a \"dead-weight\" to the gameplay. ", "Instead, her unique abilities are helpful, making her the \"brains\" while Monkey is the \"brute\". ", "Some gameplay features were cut from the final game. ", "For instance, a mechanic which allows players to break the circuitry of a mech in first-person by pressing buttons like a music game was cut because it was not well-implemented.", "\n\nSerkis considered the use of motion capture to be akin to that in a film where it helps craft the story in a virtual world. ", "The studio utilised motion capture in an effort to capture realistic human emotions. ", "The technology itself was said to be advanced, even requiring a mathematician for the more complex portions of coding. ", "Beyond facial animation, most of the motion capture was utilised prominently during the cutscenes as many of the actions within the gameplay itself were considered \"physically impossible\". ", "Serkis felt that the motion capture also allowed for better dialogue performances since it allows the actors to immerse themselves in the story, become emotionally engaged, thus delivering better performances. ", "Serkis and the performance capture team also used a physical theatre to deliver believable performances. ", "Lindsay Shaw was selected from some 60 actresses to provide performance capture for Trip at a casting session held in Los Angeles.", "\n\nGarland was also involved in the game's designs. ", "He offered advice on the positioning of the game's camera to ensure that each battle scenes was more \"impactful\". ", "The team modified Trip's idle pose in accordance with Garland's advice. ", "Garland often challenged the game's design team. ", "He demanded every object and environment detail featured in the game make sense within its world to ensure the title is consistent throughout. ", "Garland questioned the placement of random items like forest paths and powered doors for their relevance. ", "When the team chose to include random encounters with enemies, Garland insisted on adding story elements to ensure they flowed well with the game's narrative and that the combat encounter would be \"a payoff\". ", "Antoniades described Garland as \"intimidating\" and found his approach to storytelling eye-opening. ", "His high expectations caused the game's producers to fear the title would not ship on time. ", "Because of Garland's extensive involvement in the game's design, he was credited as one of its co-designers.", "\n\nNitin Sawhney, who had collaborated with Ninja Theory on Heavenly Sword, served as the game's composer. ", "According to Sawhney, the soundtrack's main theme was primarily based on \"journey, transition and resolution\", which also reflects the two protagonists' dynamic relationship. ", "Sawhney's said his second collaboration with Ninja Theory was more fluid and smooth as he had more materials like an early script and animation to use as references, while he composed the score.", "\n\nRelease\nBefore the game's release, Namco Bandai made a playable demo available over the Xbox Live and PlayStation Network on 21 September 2010. ", "The demo features the first playable chapter of the game where Monkey escapes the crashing slave ship. ", "Along with the standard edition of the game, various video game and general retailers offered exclusive extra content to those who pre-ordered it. ", "In North America alone, there were five different versions from different retailers. ", "EB Games Canada and GameStop offered a downloadable extra costume for Monkey called Ninja Monkey that came with \"rare stun and plasma blast staff ammo\". ", "Walmart offered a \"Classic Monkey\" costume based on the original tale's protagonist and Best Buy offered a robot skin for Trip. ", "Amazon offered the official soundtrack to the game while Target Corporation offered a miniature paperback comic.", "\n\nIn the UK, other retailers and websites like Game and Play.com offered similar bonuses. ", "HMV released the Talent Pack, which came in exclusive presentation packaging and included the official soundtrack and a copy of Garland's novel The Tesseract. ", "Across Europe, a Collector's Edition was also released that featured both the game's original soundtrack and a hardback art book. ", "The game was released on PlayStation 3 and Xbox 360 on 5 and 8 October 2010 in North America and Europe. ", "Namco Bandai released the game's Windows version on 25 October 2013. ", "This version, also known as the Premium Edition, bundles the base game with the Pigsy's Perfect 10 downloadable content (DLC) and several character skins. ", "It was also available for purchase via PlayStation Network.", "\n\nDownloadable content\nPigsy's Perfect 10 is a downloadable expansion to Enslaved. ", "It is a prequel to the main story where players take control of the character Pigsy. ", "It is a side-story rather than being directly linked so as to not interfere with events in Enslaved. ", "As well as the new chapters, the DLC also provides the option to display and play both the main game and the add-on in stereoscopic 3D. It uses the TriOviz for Games Technology which allows the game to display in three dimensions on 3D-HDTV set (via HDMI 1.3 or HDMI 1.4 connection) as well as on traditional 2D-HDTV sets with the Inficolor 3D glasses. ", "The DLC was first released on both platforms on 23 November 2010. ", "Several download codes for Pigsy's Perfect 10 malfunctioned, prompting Namco Bandai to issue an apology and code replacements.", "\n\nSince the player takes the role of Pigsy, the gameplay has also changed because he is a different character and build than Monkey. ", "While Pigsy can still climb over terrain, he cannot scale buildings as fast or athletically. ", "Instead, he utilises a mechanical grappling hand attached to his own to reach higher places and swing over obstacles and large gaps. ", "In combat, without the same fighting skills as Monkey, Pigsy wields a long-ranged rifle and grenades instead. ", "Stealth is also a preferable approach to gameplay, sometimes requiring avoiding combat altogether.", "\n\nReception\n\nCritical reception\n\nAccording to review aggregator Metacritic, the console version of the game received generally positive reviews from critics, while the Windows version received mixed reviews. ", "The game was nominated at the DICE Awards for Adventure Game of the Year. ", "It was also nominated at the Ivor Novello Award in the Best Original Video Game Score category. ", "Garland and Antoniades won Best Game at the UK Writers Guild Award.", "\n\nJim Sterling of Destructoid praised the \"stunning\" graphics, and found the game's colorful environments refreshing to look at. ", "He liked the performance artists' work, which he described as \"wonderful\", singling out Serkis' acting as the best of the entire cast. ", "GameSpots Tom McShea strongly commended the game's cutscenes, calling them \"superbly made\", and praised the game's reliance on character movements to tell a story rather than using dialogue. ", "Matthew Keast of GamesRadar applauded the game's world for being original and imaginative, though he thought the title needed more time before release for further polishing. ", "Eurogamers Ellie Gibson praised the game's soundtrack, describing it as \"impressive\" and praising it for further elevating the gameplay experiences. ", "Justin McElroy of Joystiq however, noted that the game had several technical issues, such as a low frame rate and occasionally clunky controls. ", "IGNs Arthur Gies called the game's graphics \"beautiful\" with unique and distinct character designs. ", "However, he shared McElroy's concern, saying there were several graphical glitches that slightly undermine the experience. ", "Andrew Reiner of Game Informer also criticized the game's lack of polish, citing texture hiccups and camera issues as key problems.", "\n\nSterling called the relationship between Trip and Monkey believable and complex, and called the game's cast one of the best of the year. ", "He also applauded the game's writing and dialogue and the story for smoothly integrating different elements from comedy to tragedy to action. ", "McElroy praised Garland's writing, and compared it favorably to Uncharted 2: Among Thieves. ", "He also liked the game's cast of characters and wanted to see more of them. ", "McShea noted that the unlikely pairing of Trip and Monkey provided a great driving force for the story and enabled players to relate and connect to them. ", "Reiner also praised the characters for being relatable, and commented on the protagonists' evolving relationship positively. ", "Gibson called the game's opening hour cliched and subpar, but he strongly praised Garland's script for avoiding needless exposition. ", "Keast agreed, describing its approach to storytelling as \"mature\". ", "Gies strong praised the story for being believable and moving, noting that it was one of the best stories in any video game.", "\n\nThe game's combat was viewed positively by Sterling. ", "He felt it is simple and satisfying, though he found the dodge mechanic for Monkey useless and that it created minor annoyances. ", "He singled out the \"Cloud\" device as one of his favorite gameplay systems, though he lamented that there are not many opportunities to use it. ", "McShea found the combat basic, requiring players to be constantly mashing buttons, though he enjoyed it for being \"brutal\" and \"satisfying\".

", "It has been disclosed, however, that briquettes formed from metallic scrap materials that have been heated to a suitably high temperature at which all volatile constituents have been vaporized and which already contain a substantial amount of preheat are desirable where further melting is scheduled. ", "Heating the scrap materials may be only a preferred procedure where smoke abatement is concerned, but it is absolutely necessary where induction melting is scheduled as a subsequent operation. ", "With the present invention there is therefore provided a briquetting press of improved design wherein metallic chips or other scrap materials being formed into briquettes are first heated to a high temperature and then they are subjected to a high compacting pressure in a fluid-cooled briquetting press that cools the press without cooling the heated chips." ]
