The article deals with the structure and function of perceptual judgment in the perception theories of the Buddhist Diṅṅāga and the Vaiśeṣika Praśastapāda. I show their indebtedness to the Vyākaraṇa tradition and particularly to Patañjali. Following Shōryū Katsura’s idea that the status of perceptual judgment with regard to the Buddhist system of instruments of valid cognition was first established by Dharmakīrti, I argue that Diṅṅāga’s examples in his definition of perception in Pramāṇasamuccaya-vṛtti I,3d could be considered as (...) class='Hi'>perceptual judgments in the sense of Charles Peirce. After the examination of Diṅṅāga’s and Praśastapāda’s examples of perceptual judgments, I come to the conclusion that Diṅṅāga, as a nominalist, sees in them an expression of ordinary linguistic behaviour shaped by convention and grammatical tradition, while Praśastapāda, as a realist, seeks to show that perceptual judgments follow the Vaiśeṣika ontological categories. If in Diṅṅāga’s epistemology perceptual judgement remains outside the pramāṇa system, in Praśastapāda’s Vaiśeṣika it pertains to the pramāṇa of perception. (shrink)

This paper deals with Peirce’s understanding of perceptual judgment, relating it to the conditions for the use of language defined by Michael Dummett. Namely, drawing on Dummett’s requirement for harmony between descriptive and evaluative aspects of our linguistic practice, we will try to give an interpretation of Peirce’s view of perception that implies rejecting the idea that the formation of a perceptual judgment has an inferential structure. On the other hand, since it is, in Peirce’s opinion, the structure (...) of abductive inference, this approach should enable us to draw some conclusions related to abduction in general. (shrink)

To what extent are cognitive capacities, especially perceptual capacities, informationally encapsulated and to what extent are they cognitively penetrable? And why does this matter? Two reasons we care about encapsulation/penetrability are: (a) encapsulation is sometimes held to be definitional of modularity, and (b) penetrability has epistemological implications independent of modularity. I argue that modularity does not require encapsulation; that modularity may have epistemological implications independently of encapsulation; and that the epistemological implications of the cognitive penetrability of perception are messier (...) than is sometimes thought.

Within current philosophy of perception John McDowell has for quite some time been defending a view inspired by Kant. Charles Travis opposes such view and counters it with his own, Frege-inspired, approach. By analysing the clash between Travis’ idea of the silence of the senses and McDowell’s idea of intuitional content, the present article aims to characterize the core of their divergence regarding the nature of perceptual judgement. It also aims at presenting their engagement as a reformulated version (...) of the debate around conceptual and nonconceptual content of perception, bringing forth some of its stakes. Such reformulated version of the debate makes it possible to bring out what a Kantian position on representation, consciousness and appearances ultimately amounts to, as well as to identify a particular angle of criticism to it.

I draw a connection between the question, raised by Hume and Kant, of how aesthetic judgments can claim universal agreement, and the question, raised in recent discussions of nonconceptual content, of how concepts can be acquired on the basis of experience. Developing an idea suggested by Kant's linkage of aesthetic judgment with the capacity for empirical conceptualization, I propose that both questions can be resolved by appealing to the idea of "perceptual normativity". Perceptual experience, on this proposal, involves (...) the awareness of its own appropriateness with respect to the object perceived, where this appropriateness is more primitive than truth or veridicality. This means that a subject can take herself to be perceiving an object as she (and anyone else) ought to perceive it, without first recognizing the object as falling under a corresponding concept. I motivate the proposal through a criticism of Peacocke's account of concept-acquisition, which, I argue, rests on a confusion between the notion of a way something is perceived, and that of a way it is perceived as being. Whereas Peacocke's account of concept-acquisition depends on an illicit slide between these two notions, the notion of perceptual normativity allows a legitimate transition between them: if someone's perceiving something a certain way involves her taking it that she ought to perceive it that way, then she perceives the thing as being a certain way, so that the corresponding concept is available to her in perceptual experience.

Some contemporary Kantians have argued that one could not be virtuous without having internalized certain patterns of awareness that permit one to identify and respond reliably to moral reasons for action. I agree, but I argue that this insight requires unrecognized, farreaching, and thoroughly welcome changes in the traditional Kantian understanding of maxims and virtues. In particular, it implies that one''s characteristic emotions and desires will partly determine one''s maxims, and hence the praiseworthiness of one''s actions. I try to show (...) this by pointing out an instability in the Kantian understanding of maxims. On the one hand, maxims are thought of as consciously affirmed, subjective principles of action. On the other hand, Kantians claim that nothing counts as an action, nor as morally assessable, unless it has a maxim. One cannot take both thoughts seriously without implausibly constricting the range of behavior that counts as action, hence as morally assessable. This difficulty can be overcome, I suggest, by jettisoning the idea that maxims must be consciously affirmed, and by stressing the way in which maxims are grounded in the pruning and shaping of one''s emotions and desires during socialization. This opens the door to a rich Kantian theory of virtue. It also raises questions about the scope and ground of our moral responsibility, which I address at the end of the paper. (shrink)

Perceptual learning involves an improvement in perceptual judgment with practice, which is often specific to stimulus or task factors. Perceptual learning has been shown on a range of visual tasks but very little research has explored chromatic perceptual learning. Here, we use two low level perceptual threshold tasks and a supra-threshold target detection task to assess chromatic perceptual learning and category effects. Experiment 1 investigates whether chromatic thresholds reduce as a result of training and (...) at what level of analysis learning effects occur. Experiment 2 explores the effect of category training on chromatic thresholds, whether training of this nature is category specific and whether it can induce categorical responding. Experiment 3 investigates the effect of category training on a higher level, lateralized target detection task, previously found to be sensitive to category effects. The findings indicate that performance on a perceptual threshold task improves following training but improvements do not transfer across retinal location or hue. Therefore, chromatic perceptual learning is category specific and can occur at relatively early stages of visual analysis. Additionally, category training does not induce category effects on a low level perceptual threshold task, as indicated by comparable discrimination thresholds at the newly learned hue boundary and adjacent test points. However, category training does induce category effects on a supra-threshold target detection task. Whilst chromatic perceptual learning is possible, learnt category effects appear to be a product of left hemisphere processing, and may require the input of higher level linguistic coding processes in order to manifest.

This paper articulates and argues for the plausibility of the Presentation View of Perceptual Knowledge, an under-discussed epistemology of perception. On this view, a central epistemological role of perception is that of making subjects aware of their surroundings. By doing so, perception affords subjects with reasons for world-directed judgments. Moreover, the very perceived concrete entities are identified as those reasons. The former claim means that the position is a reasons-based epistemology; the latter means that it endorses a radically anti-psychologist (...) conception of reasons. First, I articulate and motivate the Presentation View. Then, I defend the view from three incarnations of a major objection levelled within the ranks of reasons-based epistemologies: McDowell’s version of the accusation that a view like this falls prey to the Myth of the Given. I argue that all three incarnations fail to show the Presentation View to be inadequate. The first version holds that a general characterization of the Myth clearly shows that it is an incoherent idea. The second version holds that endorsing the Myth makes it impossible to construe non-conceptual items as items that can stand in rational relations to judgements and beliefs. The third version holds that endorsing the Myth leads to a conception where perceptual experiences merely cause, but do not warrant, our perceptual beliefs and judgements. I explain in detail how the Presentation View has the elements to respond to each of these objections. (shrink)

In his paper “There It Is” and his précis “There It Was,” Benj Hellie develops a sophisticated semantics for perceptual justification according to which perceptions in good cases can be explained by intentional psychology and can justify beliefs, whereas bad cases of perception are defective and so cannot justify beliefs. Importantly, Hellie also affords consciousness a central role in rationality insofar as only those good cases of perception within consciousness can play a justificatory function. In this commentary, I reserve (...) judgment regarding Hellie’s treatment of the rational difference between good and bad cases, but I argue there can be what he views as good cases of perceptual justification outside of consciousness.

Perceptual similarity is one of the most fiercely debated topics in the philosophy and psychology of perception. The documented history of the issue spans all the way from Plato – who regarded similarity as a key factor for human perceptual experience and cognition – through to contemporary psychologists – who have tried to determine whether, and if so, how similarity relationships can be established between stimuli both within and across the senses. Recent research on cross-sensory associations, otherwise known (...) as crossmodal correspondences – that is, the existence of observable consensual associations, or mappings, between stimuli across different senses – represents an especially interesting field in which to study perceptual similarity. In fact, most accounts of crossmodal association that have been put forward in the literature to date evoke perceptual similarity as a key explanatory factor mediating the underlying association. At the same time, however, these various accounts raise several important theoretical questions concerning the very nature of similarity, with, for example, the sensory, affective, or cognitive underpinnings of similarity judgements remaining unclear. We attempt to shed light on these questions by examining the various accounts of crossmodal associations that have been put forward in the literature. Our suggestion is that perceptual similarity varies from being phenomenologically-based to conceptually-based. In particular, we propose that the nature of the associations underlying similarity judgements – whether these associations are phenomenologically-, structurally-, emotionally-, or conceptually-based – may be represented in a two-dimensional space with associative strength on one axis, and cognitive penetrability on the other.

I defend indirect perceptual realism against two recent and related charges to it offered by A. D. Smith and P. Snowdon, both stemming from demonstrative reference involving indirect perception. The needed aspects of the theory of demonstratives are not terribly new, but their connection to these objections has not been discussed. The groundwork for my solution emerges from considering normal cases of indirect perception (e.g., seeing something depicted on a television) and examining the role this indirectness plays in demonstrative (...) assertions. I argue that indirectness routinely if not typically plays a justificatory role in such judgements, and not a semantic one, and that the same can be said of such judgements when considered within the indirect realist framework. The denial of this, on my analysis, is essential to the criticisms of Snowdon and Smith. The discussion is extended to include scenarios involving the sorts of misconceptions Smith employs. (shrink)

I argue that the descriptions of perceptual experience offered by Kant and Merleau-Ponty are, contrary to what many commentators suppose, largely compatible. This is because the two are simply referring to different things when they talk about experience: Kant to empirical cognition and Merleau-Ponty to perception. Consequently, while Merleau-Ponty correctly denies that Kant accurately describes the conditions for the possibility of perception, Kant nevertheless provides a plausible account of the conditions of empirical judgment. Further, the two approach experience with (...) different standards of normativity: Kant with the standard of justification, but Merleau-Ponty with the standard of what he calls “motivation”. I exemplify this approach through an analysis of the Second Analogy of Experience. (shrink)

Francois Recanati presents the basic features of the *indexical model* of mental files, and defends it against several interrelated objections. According to this model, mental files refer to objects in a way that is analogous to that of indexicals in language: a file refers to an object in virtue of a contextual relation between them. For instance, perception and attention provide the basis for demonstrative files. Several objections, some of them from David Papineau, concern the possibility of files to preserve (...) and add information about objects across contexts. How is it possible to think about the same object when the subject no longer is in the original context? How is it possible to think of a perceived object as already known? Can this be done without an explicit identity judgment? Recanati answers these questions by invoking mental files of non-basic kinds and by describing the cognitive dynamics in which they take part.

Doxasticism about our awareness of normative (i.e. justifying) reasons – the view that we can recognise reasons for forming attitudes or performing actions only by means of normative judgements or beliefs – is incompatible with the following triad of claims: -/- (1) Being motivated (i.e. forming attitudes or performing actions for a motive) requires responding to and, hence, recognising a relevant reason. -/- (2) Infants are capable of being motivated. -/- (3) Infants are incapable of normative judgement or belief. (...) -/- It should be clear that (3) is true, given that infants lack the required reflective and conceptual capacities. So doxasticists have to reject either (1) or (2) (or both). But this forced choice may be understood as a dilemma for doxasticism. On the hand, doxasticists may adopt a Kantian approach and reject (2), precisely because they think that motivation presupposes the doxastic recognition of reasons, and because infants lack the capacity to doxastically recognise reasons. But this choice seems to wrongly reduce the responses of infants to mere reflexes or instinctive reactions. On the other hand, doxasticists may choose a Humean route and deny (1) by espousing a purely causal or teleological account of motivation. But this would mean detrimentally ignoring the normative nature of (some instances of) motivation. -/- One elegant way of avoiding this dilemma is to give up doxasticism and instead endorse experientialism – the view that we enjoy some experiential access to reasons, which is independent of, and perhaps more fundamental than, our capacity to form normative judgements and beliefs. In this talk, I would like to provide an argument for the existence of such a non-doxastic form of access to reasons. More specifically, I aim to defend the claim that our basic awareness of reasons is phenomenal in nature. What this means is that it forms part of our access from the inside to those of our mental episodes that provide us with access to reasons. In other words, when we introspectively attend to reason-giving mental episodes and what they are about, we have the impression of the presence of a reason for us. My defence of this experientialist alternative to doxasticism will primarily focus on perceptual reasons for first-order beliefs about the external world. (shrink)

There are a number of problems associated with the classic notion of beauty understood as an experience of perceptual form. These problems are that there is an apparent incompatibility between beauty’s objectivity and subjectivity; and an incompatibility between the two self-evident theses that (i) there are no principles of beauty and (ii) there are genuine judgements of beauty. There is also the problem of explaining the possibility of a disinterested pleasure. To solve these problems I draw upon the work (...) of Glyn Humphreys & Dietmar Heinke (1998) according to whom the processing of ‘between-object’ relations draws upon view-dependent primitives and the processing of ‘within-object’ relations draws upon view-invariant primitives. I argue that if what we experience as aesthetic form or beauty is some kind of play on the processes involved in processing within-object-relations during the course of perceiving certain objects, then the apparent problems of beauty would be resolved. I speculate that perhaps the perception of certain objects employs perceptual principles in an unprecedented way or in a way which epitomizes their normal operation. The idea is that when perception is employed in such a way that our attention is drawn from the object recognized to the experience of perception as something like a solution to a problem (that is, to the experience of the construction of within-object relations), then we experience what we know of as aesthetic form and beauty.

Epistemological disjunctivism says that one can know that p on the rational basis of one’s seeing that p. The basis problem for disjunctivism says that that can’t be since seeing that p entails knowing that p on account of simply being the way in which one knows that p. In defense of their view disjunctivists have rejected the idea that seeing that p is just a way of knowing that p (the SwK thesis). That manoeuvre is familiar. In this paper (...) I explore the prospects for rejecting instead the thought that if the SwK thesis is true then seeing that p can’t be one’s rational basis for perceptual knowledge. I explore two strategies. The first situates disjunctivism within the context of a ‘knowledge-first’ approach that seeks to reverse the traditional understanding of the relationship between perceptual knowledge and justification (or rational support). But I argue that a more interesting strategy situates disjunctivism within a context that accepts a more nuanced understanding of perceptual beliefs. The proposal that I introduce reimagines disjunctivism in light of a bifurcated conception of perceptual knowledge that would see it cleaved along two dimensions. On the picture that results perceptual knowledge at the judgemental level is rationally supported by perceptual knowledge at the merely functional or ‘animal’ level. This supports a form of disjunctivism that I think is currently off the radar: one that’s consistent both with the SwK thesis and a commitment to a traditional reductive account of perceptual knowledge.

How are causal judgements such as 'The ice on the road caused the traffic accident' connected with counterfactual judgements such as 'If there had not been any ice on the road, the traffic accident would not have happened'? This volume throws new light on this question by uniting, for the first time, psychological and philosophical approaches to causation and counterfactuals. Traditionally, philosophers have primarily been interested in connections between causal and counterfactual claims on the level of meaning or truth-conditions. More (...) recently, however, they have also increasingly turned their attention to psychological connections between causal and counterfactual understanding or reasoning. At the same time, there has been a surge in interest in empirical work on causal and counterfactual cognition amongst developmental, cognitive, and social psychologists--much of it inspired by work in philosophy. In this volume, twelve original contributions from leading philosophers and psychologists explore in detail what bearing empirical findings might have on philosophical concerns about counterfactuals and causation, and how, in turn, work in philosophy might help clarify the issues at stake in empirical work on the cognitive underpinnings of, and relationships between, causal and counterfactual thought.

Social Judgement Theory (SJT) evolved from Egon Brunswik's Probabilistic Functionalist psychology coupled with multiple correlation and regression-based statistical analysis. Through its representational device, the Lens Model, SJT has become a widely used, systems-oriented perspective for analysing human judgement in specific ecological circumstances. Judgements are assumed to result from the integration of different cues or sources of perceptual information from the environment. Special advantages accrue to the SJT approach when criterion values (or correct values) for judgement are (...) also available, as this permits the comparison of judgement processes to environmental processes and leads naturally to the generation of cognitive feedback as an aid to facilitate learning. In contrast to more prescriptive approaches to decision analysis, the SJT approach analyses judgements by decomposing the judgement process after judgements have been rendered. This a posteriori decomposition is accomplished by first using multiple regression analysis to recover prediction equations for both the judgement and ecological systems and then using the Lens Model Equation to compare those systems. SJT methods maintain close contact with ecological circumstances by employing the principle of representative design (which focuses on how the researcher obtains the stimuli for judgement) and avoiding unwarranted over-generalisations from nomothetic aggregation (e.g. averaging across judges) through the use of idiographic statistical analysis. SJT methods have proven valuable in the analysis of individual judgements as well as groupbased judgements where conflict becomes likely. (shrink)

‘Judgment’ is Brentano’s terms for any mental state liable to be true or false. This includes not only the products of conceptual thought, such as belief, but also perceptual experiences, such as seeing that the window was left open. ‘Every perception counts as a judgment,’ writes Brentano (1874: II, 50/1973a: 209). Accordingly, his theory of judgment is not exactly a theory of the same phenomenon we call today ‘judgment,’ but of a larger class of phenomena one (perhaps the main) (...) species of which is what we call judgment. Even if we keep this in mind, though, the profound heterodoxy of Brentano’s theory of judgment is still striking. Brentano develops this heterodox theory in some detail already in the Psychology from Empirical Standpoint (Brentano 1874/1973a). But he continued to work out its details, and various aspects of it, until his death. Many of the relevant articles, notes, and fragments of relevance have been collected by Oskar Kraus in 1930 and published under the title Truth and Evidence (Brentano 1930/1966b). Kraus prefaces this volume with an elaborate reconstruction, of dubious plausibility, according to which Brentano’s accounts of judgment and truth have gone through four distinct stages. In reality, there is a unified underlying conviction underwriting Brentano’s work both on judgment and on truth (see CHAP. 20 on the latter). Here I present this unified core of this highly original theory of judgment, which can be captured in terms of three main theses. The first is that contrary to appearances, all judgments are existential judgments (§1). The second is that the existential force of judgment is indeed a force, or mode, or attitude – it does not come from the judgment’s content (§2). The third is that judgment is not a propositional attitude but an ‘objectual’ attitude (§3). (shrink)

This paper comments on an article by V.S. Ramachandran and William Hirstein (JCS,1999) in which they purport to be identifying the neurological principles of beauty. I draw attention to the way the problem of beauty is construed in the philosophical literature by Mary Mothersill (1984) and Immanuel Kant (Critique of Judgment). I argue that Ramachandran and Hirsteins' principles do not address the problem of beauty because they do not differentiate between the experience of beauty and other closely related phenomena. I (...) then show how one might address the problem of beauty within the framework that they have adopted. (shrink)

When an elastic material is horizontally stretched, the material is compressed vertically – so-called the Poisson effect. In the different case of the Poisson effect, when an elastic material is vertically squashed, the material is horizontally extended. In both cases, the visual system receives image deformations involving horizontal expansion and vertical compression. How does the brain disentangle the two cases and accurately distinguish stretching from squashing events? Manipulating the relative magnitude of the deformation of a square between horizontal and vertical (...) dimensions in the two-dimensional stimuli, we asked observers to judge the force direction in the stimuli. Specifically, the participants reported whether the square was stretched or squashed. In general, the participant’s judgment was dependent on the relative deformation magnitude. We also checked the anisotropic effect of deformation direction [i.e., horizontal vs. vertical stretching ] and found that the participant’s judgment was strongly biased toward horizontal stretching. We also observed that the asymmetric deformation pattern, which indicated the specific context of force direction, was also a strong cue to the force direction judgment. We suggest that the brain judges the force direction in the Poisson effect on the basis of assumptions about the relationship between image deformation and force direction, in addition to the relative image deformation magnitudes between horizontal and vertical dimensions.

Ferreira outlines Bradley’s account of judgment and perception, and then, towards the end of his essay, indicates the sort of reason that Bradley takes to be an argument in favour of his views. I want to look at that argument, but will first summarize Ferreira’s account of Bradley’s views. This account seems to me to make a very important point about the role of feeling in Bradley’s philosophy, specifically that feeling in Bradley’s ontology/epistemology has a very different status and role (...) from that of the feeling=sensation of the empiricists. The latter is indeed “mere” feeling, from Bradley’s point of view, but that feeling which plays a central role in his own philosophy is anything but mere. (shrink)

Many studies have reported neural correlates of visual awareness across several brain regions, including the sensory, parietal, and frontal areas. In most of these studies, participants were instructed to explicitly report their perceptual experience through a button press or verbal report. It is conceivable, however, that explicit reporting itself may trigger specific neural responses that can confound the direct examination of the neural correlates of visual awareness. This suggests the need to assess visual awareness without explicit reporting. One way (...) to achieve this is to develop a technique to predict the visual awareness of participants based on their peripheral responses. Here, we used eye movements and pupil sizes to decode trial-by-trial changes in the awareness of a stimulus whose visibility was deteriorated due to adaptation-induced blindness. In the experiment, participants judged whether they perceived a target stimulus and rated the confidence they had in their perceptual judgment, while their eye movements and pupil sizes were recorded. We found that not only perceptual decision but also perceptual confidence can be separately decoded from the eye movement and pupil size. We discuss the potential of this technique with regard to assessing visual awareness in future neuroimaging experiments. (shrink)

The book addresses the debate on whether the representational content of perceptual experience is conceptual or non-conceptual, by bringing out the points of comparison between Kant s conception of intuition and contemporary accounts of non-conceptual content. It is argued that intuition provides the most basic form of intentionality pre-conceptual reference to objects, which underlies the acts of conceptualization and judgment.".

This book assesses and defends Kant's Critical epistemology, and the rich yet neglected resources it provides for understanding and resolving fundamental issues regarding human experience, perceptual judgment, empirical knowledge and cognitive sciences. Kenneth Westphal first examines Kant's methods and strategies for examining human sensory-perceptual experience, and then examines Kant's central, proper, and subtle attention to judgment, and so to the humanly possible valid use of concepts and principles to judge particulars we confront. This provides a comprehensive account of (...) Kant's anti-Cartesianism, the integrity of his three principles of causal judgment, and Kant's account of disciminatory perceptual-motor behaviour, including both sensory reafference and perceptual affordances. Westphal then defends the significance of Kant's subtle and illuminating account of causal judgment for three main philosophical domains: history and philosophy of science, theory of action and human freedom, and philosophy of mind. Kant's Critical Epistemology will appeal to researchers and advanced students interested in Kant and the relations of his thought to contemporary philosophical debates and to the sciences of the mind.

Aesthetic non-inferentialism is the widely-held thesis that aesthetic judgements either are identical to, or are made on the basis of, sensory states like perceptual experience and emotion. It is sometimes objected to on the basis that testimony is a legitimate source of such judgements. Less often is the view challenged on the grounds that one’s inferences can be a source of aesthetic judgements. This paper aims to do precisely that. According to the theory defended here, aesthetic judgements may be (...) unreasoned, insofar as they are immediate judgements made on the basis of, and acquiring their justification from, causally prior sensory states. Yet they may also be reasoned, insofar as they may be the outputs of certain inferences. Crucially, a token aesthetic judgement may be unreasoned and reasoned, simultaneously. A key reason for allowing inference a serious role in aesthetic judgements emerges from reflection upon the nature of aesthetic expertise. (shrink)

Perception can provide us with a privileged source of evidence about the external world – evidence that makes it rational to believe things about the world. In Reasons First, Mark Schroeder offers a new view on how perception does so. The central motivation behind Schroeder’s account is to offer an answer to what evidence perception equips us with according to which it is what he calls world-implicating but non-factive, and thereby to glean some of the key advantages of both externalism (...) and internalism, respectively. He answers this motivation by developing a more specific view that he calls the Apparent Factive Attitude view, which pairs an answer to what evidence is provided by a perceptual experience with an answer to why having that perceptual experience provides you with that evidence. In this paper we advance two interconnected problems for Schroeder’s Apparent Factive Attitude view. A traditional intuitive judgment that often motivates internalists is the idea that internal duplicates must necessarily be equally rational in whatever beliefs they have. Schroeder’s arguments rely on a weaker claim - that people who are both internal and historical external duplicates but differ only in the veridicality of a single perceptual experience must be equally rational in whatever beliefs they have. In this way he preserves what he argues to be a more compelling internalist intuition. But our arguments will show that Schroeder’s view is committed to denying an even more compelling internalist intuition yet - that internal duplicates must have the same phenomenology. (shrink)

This essay deals with the problem of the status of colours, traditionally considered as the paradigmatic case of secondary qualities: do colours exist only as aspects of experience or are they real properties of objects, existing independently of human and animal perception?

High-level theory is the view that high-level properties---the property of being a dog, being a tiger, being an apple, being a pair of lips, etc.---can be represented in perceptual experience. Low-level theory denies this and claims that high-level properties are only represented at the level of perceptual judgment and are products of cognitive interpretation of low-level sensory information (color, shape, illumination). This paper discusses previous attempts to establish high-level theory, their weaknesses, and an argument for high-level theory that (...) does not have these weaknesses. (shrink)
