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)

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.

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)

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)

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 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)

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)

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.

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.

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)

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.

The views are original, and there is substantive engagement among contributors. This collection will stimulate future research in this area.

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)

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.

There would be no Edenic content, hence no two-stage view, if there was no such thing as the perfect veridicality conditions of experiences, where these diverged from ordinary veridicality conditions. (From now on, I’ll just take as definitional that perfect veridicality conditions, if there are such, diverge from ordinary veridicality conditions). A central substantive claim in Chalmers’s paper is that perceptual experiences have perfect veridicality conditions. And not just ones associated with color experience, but ones associated with many other aspects (...) of visual experience, as well as with perceptual experiences in other modalities as well. In defending this view, I think Chalmers brings into focus quite a strong claim about the relation between phenomenology on the one hand and accuracy conditions on the other. Say that an experience has accuracy conditions if there are ways the world would have to be, for the experience to be accurate, and accuracy is truth. And say it’s definitional of events that are perceptual experiences that in undergoing them, the subject has some sort of phenomenology or other. I’m going to take for granted that it makes sense to talk about experiences having exactly the same phenomenology, or being phenomenally the same (some philosophers think it doesn’t make sense to talk this way).

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.

The paper proposes a novel interpretation of Berkeley's so-called Assimilation Argument in the First Dialogue between Hylas and Philonous.

In examining the puzzle of experience, and its possible solutions, Valberg discusses relevant views of Hume, Kant, Heidegger, Wittgenstein, and Strawson, as well as ideas from the recent philosophy of perception. Finally, he describes and analyzes a manifestation of the puzzle outside philosophy, in everyday experience.
