Some issues heavily debated in perception sciences are presented: the explanatory gap and the experience measurement problem. The experimental phenomenology is said to provide substantive contribution to settle controversy over the phenome- nological adequacy of perception theory and models. An interpretation of experi- mental phenomenology as explanation of the perceptual manifold, and definition of relation varieties to eventually map onto other perception sciences’ domains is sketched.

What are intuitions? According to doxastic views, they are doxastic attitudes or dispositions, such as judgments or inclinations to make judgments. According to perceptualist views, they are—like perceptual experiences—pre-doxastic experiences that—unlike perceptual experiences—represent abstract matters as being a certain way. In this paper I argue against doxasticism and in favor of perceptualism. I describe two features that militate against doxasticist views of perception itself: perception is belief-independent and perception is presentational. Then I argue that intuitions also have both features. The (...) upshot is that intuitions are importantly similar to perceptual experiences, and so should not be identified with doxastic attitudes or dispositions. I consider a popular argument from the introspective absence of sui generis intuition experiences in favor of doxasticism. I develop a conception of intuition experiences that helps to defuse this argument. (shrink)

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, the question can be confused (...) with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. Some philosophers (e.g. Brewer 2000) have argued that there is a distinctively philosophical question here, but it is epistemological, viz. how does perception provide 1 reason for our beliefs about the empirical world? This, it seems, is a question which remains to be answered even after the empirical world is done. This is because the question about reasons is normative rather than scientific or descriptive. Even once the psychological theory of vision, for example, has done its job in describing fully the mechanisms of vision, the normative question still can be asked: what makes this process result in something which gives a reason, something which justifies a belief? Suppose I see a bottle before me, and come to believe on the basis of this that there is a bottle before me. My reason for believing that this is a bottle is that I can see it. But what makes seeing the bottle a reason for this belief? It can be argued that the need to give a satisfactory answer to this question constrains our choice of theory of perception.. (shrink)

Sense-perception—the awareness or apprehension of things by sight, hearing, touch, smell and taste—has long been a preoccupation of philosophers. One pervasive and traditional problem, sometimes called “the problem of perception”, is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perception be what it intuitively seems to be, a direct and immediate access to reality? The present entry is about how these possibilities of error challenge the intelligibility of the phenomenon of (...) perception, and how the major theories of perception in the last century are best understood as responses to this challenge.

Reflection on cases involving the occurrence of various types of perceptual activity suggests that the phenomenal character of perceptual experience can be partly determined by agential factors. I discuss the significance of these kinds of case for the dispute about phenomenal character that is at the core of recent philosophy of perception. I then go on to sketch an account of how active and passive elements of phenomenal character are related to one another in activities like watching and looking at (...) things. (shrink)

La connaissances noyau de la géométrie euclidienne est liée au raisonnement déductif et non à la reconnaissance de motifs perceptuels.

In this paper we consider, and reject, Harold Langsams defenceof the Theory of Appearing, in this journal (1997), in the faceof three standard arguments against it. These arguments are:the argument from hallucination; the argument from the samecause-same effect principle; and the argument from perceptualtime-gap.

It is widely assumed that perception is a source of reasons (SR). There is a weak sense in which this claim is trivially true: even if one characterizes perception in purely causal terms, perceptual beliefs originate from the mind's interaction with the world. When philosophers argue for (SR), however, they have a stronger view in mind: they claim that perception provides pre- or non-doxastic reasons for belief. In this article I examine some ways of developing this view and criticize them. (...) I exploit these results to formulate a series of constraints that a satisfactory account of the epistemic role of perception should fulfil. I also make a positive suggestion: coherentists are right when they claim that only beliefs can be reasons for other beliefs. Nevertheless, I depart from traditional coherentism, for I do not buy its conception of perception as bare sensation, nor explicate the justificatory status of beliefs in terms of coherence. My point is rather that, when one invokes experience to justify a belief, the justifying state must have structural features of beliefs. (shrink)

It is argued that both neuroscience and physics point towards a similar re-assessment of our concepts of space, time and 'reality', which, by removing some apparent paradoxes, may lead to a view which can provide a natural place for consciousness and language within biophysics. There are reasons to believe that relationships between entities in experiential space and time and in modern physicists' space and time are quite different, neither corresponding to our geometric schooling. The elements of the universe may be (...) better described not as 'particles' but as dynamic processes giving rise, where they interface with each other, to the transfer, and at least in some cases experience, of 'pure'or 'active'information, the mental and physical just reflecting different standpoints. Although this analy-sis draws on general features of quantum dynamics, it is argued that purely quantum level events (and their 'interpretations') are unlikely to be relevant to the understanding of consciousness. The processes that might be able to give rise, within brain cells, to an experience like ours are briefly reviewed. It is suggested that the elementary signals that are integrated to generate a spatial experience may have features more in common with words than pixels. It is further suggested that the laws of integration of words in language may provide useful clues to the way biophysical integration of signals in neurons relates to integration of elements in experiential space.

Intentionality is customarily characterised as the mind’s direction upon its objects. This characterisation allows for a number of different conceptions of intentionality, depending on what we believe about the nature of the objects or the nature of the direction. Different conceptions of intentionality may result in classifying sensory experience as intentional and nonintentional in different ways. In the first part of this paper, I present a certain view or variety of intentionality which is based on the idea that the intentional (...) object of a sensory experience must be Independent; that is, an intentional object must be such that its existence doesn’t depend on being experienced (except in some very special cases). This means, for example, that sense-data understood as mind-dependent objects are not intentional objects, because their existence depends on the occurrence of an experience. In the second part of the paper, I will sketch a view of how sensory experiences can acquire an Independent object. (shrink)

The dominant view among philosophers of perception is that color experiences, like color judgments, are essentially representational: as part of their very nature color experiences possess representational contents which are either accurate or inaccurate. My starting point in assessing this view is Sydney Shoemaker’s familiar account of color perception. After providing a sympathetic reconstruction of his account, I show how plausible assumptions at the heart of Shoemaker’s theory make trouble for his claim that color experiences represent the colors of things. (...) I consider various ways of trying to avoid the objection, and find all of the responses wanting. My conclusion is that we have reason to be skeptical of the orthodox view that color experiences are constitutively representational. (shrink)

A central question, if not the central question, of philosophy of perception is whether sensory states have a nature similar to thoughts about the world, whether they are essentially representational. According to the content view, at least some of our sensory states are, at their core, representations with contents that are either accurate or inaccurate. Tyler Burge’s Origins of Objectivity is the most sustained and sophisticated defense of the content view to date. His defense of the view is problematic in (...) several ways. The most significant problem is that his approach does not sit well with mainstream perceptual psychology. (shrink)

This is a critical review of Tyler Burge's book, Origins of Objectivity. Criticism focuses on Burge's claim that perceptions represent particulars as belonging to kinds.

Davidson claims that nothing can count as a reason for a belief except another belief. This claim is challenged by McDowell, who holds that perceptual experiences can count as reasons for beliefs. I argue that McDowell fails to take account of a distinction between two different senses in which something can count as a reason for belief. While a non-doxastic experience can count as a reason for belief in one of the two senses, this is not the sense which is (...) presupposed in Davidson's claim. While I focus on McDowell's view, the argument generalizes to other views which take experiences as reasons for belief. (shrink)

Quine's Immanuel Kant lectures were delivered in English at Stanford University in 1980 under the title Science and Sensibilia. The English version of the text has never been published. An Italian translation by Michele Leonelli, La Scienza e I Dati di Senso appeared in 1987. These translations fill an important gap. Wissenschaft und Empfindung strikes me as the best presentation of Quine's physicalistic program.

J. A. Gray et al. have recently argued that synaesthesia can be used as a counterexample to functionalism. They provide empirical evidence which they hold supports two anti-functionalist claims: disparate functions share the same types of qualia and the effects of synaesthetic qualia are, contrary to what one would expect from evolutionary considerations, adverse to those functions with which those types of qualia are normally linked. I argue that the empirical evidence they cite does not rule out functionalism, rather the (...) reverse. The fact that the effects of synaesthesia are adverse shows that understanding synaesthetic experiences requires a concept of dysfunction, which in turn presupposes a functionalist account. Such an account, moreover, shows how tokens of the same types of qualia can be associated with different causal histories, thus disarming their first objection. (shrink)

An overview of the philosophy and psychology of hallucination and its relevance to the philosophy of perception.

This paper provides a categorization of cross-modal experiences. There are myriad forms. Doing so allows us to think clearly about the nature of different cross-modal experiences and allows us to clearly formulate competing hypotheses about the kind of experiences involved in different cross-modal phenomena.

This paper provides an introduction to, and overview of, the Philosophy of Perception.

This thesis is an examination and critique of naturalistic representational theories of phenomenal character. Phenomenal character refers to the distinctive quality that perceptual and sensational experiences seem to have; it is identified with 'what it is like' to undergo experiences. The central claims of representationalism are that phenomenal character is identical with the content of experience and that all representational states, bearing appropriate relations to the cognitive system, are conscious experiences. These claims are taken to explain both how conscious experiential (...) states arise and their nature. After examining the desiderata for naturalistic explanations, I argue that theories which ascribe nonconceptual content to experiences are the most plausible versions of representationalism. Further, causal covariation and teleological theories yield distinctive and interesting representationalist positions, hence, they become the focus of this study. To assess representationalism, I investigate whether all differences in phenomenal character can be correlated with differences in content. I claim that a useful distinction can be drawn between implicit and explicit content, which allows one to best describe the phenomena of perfect and relative pitch. I then argue that ambiguous figures show that two experiences can have the same content but different phenomenal character. I explicate the Inverted Earth hypothesis and claim that to identify content and phenomenal character, representationalists either have to condone the possibility of philosophical zombies, or hold that people lack authoritative first-person knowledge of their current experiences. Both these positions are unpalatable. Finally, I argue that representationalists cannot ascribe contents to experiences of novel colours to account for their phenomenal character. I also question, in light of dissociation phenomena, whether there is one distinctive relationship that all experiences bear to the cognitive system. I conclude that phenomenal character cannot be identical with the type of content under investigation, and that naturalistic representationalist theories cannot fully explain conscious experience.

I present a view of conscious perception that supposes a processual unity between the activity in the brain and the perceived event in the external world. I use the rainbow to provide a first example, and subsequently extend the same rationale to more complex examples such as perception of objects, faces and movements. I use a process-based approach as an explanation of ordinary perception and other variants, such as illusions, memory, dreams and mental imagery. This approach provides new insights into (...) the problem of conscious representation and phenomenal consciousness. It is a form of anti- cranialism different from but related to other kinds of externalism. (shrink)

The perceptual symbol system view assumes that perceptual representations have a role-argument structure. A role-argument structure is often incorporated into amodal symbol systems in order to explain conceptual functions like abstraction and rule use. The power of perceptual symbol systems to support conceptual functions is likewise rooted in its use of structure. On Barsalou's account, this capacity to use structure (in the form of frames) must be innate.

The problems of perception feature centrally in work within what we now think of as different traditions of philosophy in the early part of the twentieth century, most notably in the sense-datum theories of early analytic philosophy together with the vigorous responses to them over the next forty years, but equally in the discussions of pre-reflective consciousness of the world characteristic of German and French phenomenologists. In the English-speaking world one might mark the beginning of the period with Russell’s The (...) Problems of Philosophy (Russell 1912) and its nemesis in Austin’s Sense and Sensibilia (Austin 1962 – published posthumously, but given originally as lectures at the end of our period in 1947). On the continent, a corresponding route takes us from Husserl’s Logical Investigations (Husserl 1900/1) to Merleau-Ponty’s Phenomenology of Perception.. (shrink)

Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from. With your eyes again fixed on the speaker, and the movement of her lips a clear sense of the source of the sound will (...) return. This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception. And this phenomenological observation is one that you can verify or disconfirm in your own case just by the slightest reflection on what it is like for you to listen to someone with or without visual contact with them.

A theory of perception must be capable of explaining the full range of conscious perception, including amodal perception. In amodal perception we perceive the world to contain physical features that are not directly detectable by the sensory receptors. According to the active-externalist theory of perception, amodal perception depends on active engagement with perceptual objects. This paper focuses on amodal visual perception and presents a counter-example to the idea that active-externalism can account for amodal perception. The counterexample involves the experience of (...) so-called ‘impossible objects’, objects experienced in perceptual character as having geometrical properties that no physically real object can have.

What colour does a white wall look in the pinkish light of the late afternoon? Philosophers disagree: they hold variously that it looks pink, white, both, and no colour at all. A new approach is offered. After reviewing the dispute, a reinterpretation of perceptual constancy is offered. In accordance with this reinterpretation, it is argued that perceptual features such as color must always be predicated of perceptual objects. Thus, it might be that in pinkish light, the wall looks white and (...) the light looks pink. The paper concludes by discussing some criteria for object identification in perceptual states. (shrink)

Argues for a category of “cognitive feelings”, which are representationally significant, but are not part of the content of the states they accompany. The feeling of pastness in episodic memory, of familiarity (missing in Capgras syndrome), and of motivation (that accompanies desire) are examples. The feeling of presence that accompanies normal visual states is due to such a cognitive feeling; the “two visual systems” are partially responsible for this feeling.

This a review of Alva Noë's Action in Perception. It argues that a distinction should be made between the proposition that sensorimotor feedback is used in sensory perception and that perception is of sensorimotor features of the world. Noë fails to make this distinction.

What sort of an episode is perception? What are the objects of such episodes? What is the grammatical and logical form of perceptual reports, direct and indirect? Each of these questions has been the subject of recent discussion. In what follows I set out one answer to each of them and explore some of the ways these answers support and complement each other. The answers adopted are: to perceive - and I shall normally only have in mind visual perception - (...) is not to judge or to conceptualize but a sui generis mental mode or activity involving non-conceptual content; perception is of particulars only; the complements of perceptual verbs are, with one exception, non-propositional and indirect perceptual reports are made true by direct perceptual relations between subjects and particulars of various sorts.

The notion that there is a category mistake or some other conceptual confusion in regarding seeing, hearing, and other forms of perception as events, states, or processes is incorrect. Ryle's analysis of "seeing" as an achievement word does not rule out our regarding seeing as an event, but in fact suggests that we do so when we carry the analysis beyond the point where Ryle leaves it. Furthermore there are uses of "see" not noticed by Ryle which justify our saying (...) that within certain contexts seeing is a state and within other contexts a process. The question of what these events, states, and processes are cannot be met without recognizing a fundamental duality of aspect that characterizes perception. This duality can be formulated in terms of the way perception is known. One who observes a perceiver knows the perceiver's perception in a categorically different way than the perceiver knows it. From this it can be seen that perceptual events, states, and processes have both a physical aspect and an epistemological aspect. Any attempt to reduce one of these aspects to the other would involve a category mistake. (shrink)

‘Experience is the best teacher’ goes the cliché without ever making clear just want is meant by that slippery first term. ‘Experience is never remembered unaltered’ goes another. Is experience something to be undergone, like a journey, or is it perhaps the relational immediacy between organism and environment? What do we reference when we use the term experience? -/- Martin Jay, renowned intellectual historian from UC Berkeley, here examines these questions in a grand survey of the term’s use throughout the (...) intellectual history of what was once called Western Civilization. Beginning with the ancient Greeks (of course), he reviews the surprising number of variations employed and assumed by philosophers, theologians critical theorists, and right up to the poststructuralists. Jay knows his territory and reading this survey of it — for anyone with any sort of background in the history of philosophy — is often as pleasant as hearing a familiar symphony well-played in a unique way.

Recent work on non-visual modalities aims to translate, extend, revise, or unify claims about perception beyond vision. This paper presents central lessons drawn from attention to hearing, sounds, and multimodality. It focuses on auditory awareness and its objects, and it advances more general lessons for perceptual theorizing that emerge from thinking about sounds and audition. The paper argues that sounds and audition no better support the privacy of perception’s objects than does vision; that perceptual objects are more diverse than an (...) exclusively visual perspective suggests; and that multimodality is rampant. In doing so, it presents an account according to which audition affords awareness as of not just sounds, but also environmental happenings beyond sounds. (shrink)

Key issues in the philosophy of mind, examined by leading figures in the field.

Wittgenstein remarks in the "Tractatus" that the eye is not in the visual field. I question the claim of Michael Dummett and P T Geach that reflection on this remark helps one conceive of an observer perceiving objects in space without having any location in that space. The literal meaning of "point of view" is illustrated by the visual field. Reflection on the fact that the point of view is not itself normally an object of sight is no help in (...) conceiving perception from no point of view. (shrink)

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content apply only to (...) accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational. (shrink)

I argue that any account of perceptual experience should satisfy the following two desiderata. First, it should account for the particularity of perceptual experience, that is, it should account for the mind-independent object of an experience making a difference to individuating the experience. Second, it should explain the possibility that perceptual relations to distinct environments could yield subjectively indistinguishable experiences. Relational views of perceptual experience can easily satisfy the first but not the second desideratum. Representational views can easily satisfy the (...) second but not the first desideratum. I argue that to satisfy both desiderata perceptual experience is best conceived of as fundamentally both relational and representational. I develop a view of perceptual experience that synthesizes the virtues of relationalism and representationalism, by arguing that perceptual content is constituted by potentially gappy de re modes of presentation. (shrink)

In this paper I consider one of the influential challenges to the notion that perceptual experience might be completely conceptually structured, a challenge that rests on the idea that conceptual structure cannot do justice to the fineness of grain of perceptual experience. In so doing, I canvass John McDowell's attempt to meet this challenge by appeal to the notion of demonstrative concepts and review some criticisms recently leveled at McDowell's deployment of demonstrative concepts for this purpose by Sean D. Kelly. (...) Finally, I suggest that, though Kelly's criticisms might challenge McDowell's original presentation of demonstrative concepts, a modified notion of demonstrative concepts is available to the conceptualist that is proof against Kelly's criticisms.

This paper defends the Content View: the thesis that all visual experiences have contents.

In this paper we shall address some issues concerning the relation between the content and the nature of perceptual experiences. More precisely, we shall ask whether the claim that perceptual experiences are by nature relational implies that they cannot be intentional. As we shall see, much depends in this respect on the way one understands the possibility for one to be wrong about the phenomenal nature of one's own experience. We shall describe and distinguish a series of errors that can (...) occur in our introspective access to our perceptual experiences. We shall argue that once the nature of these different kinds of error are properly understood, the metaphysical claim that perceptual experiences are relational can be seen to be compatible with the view that they are intentional.
