This is the editors' Introduction to a special issue of the journal, Multisensory Research. European philosophers of the modern period found multisensory perception to be impossible because they thought that perceptual ideas are defined by how they are experienced. Under this conception, the individual modalities are determinables of ideas—just as colour is a determinable that embraces red and blue, so also the visual is a determinable that embraces colour and (visually experienced) shape. Since no idea is experienced as, for (...) example, both visual and auditory, there can be no such thing as audiovisual perception. This conception of modality is not directly contested, but a variety of perceptual phenomena are listed that could raise interesting questions if treated as multimodal in origin. (shrink)

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was (...) also very influential in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

Zero provides a challenge for philosophers of mathematics with realist inclinations. On the one hand it is a bona fide cardinal number, yet on the other it is linked to ideas of nothingness and non-being. This paper provides an analysis of the epistemology and metaphysics of zero. We develop several constraints and then argue that a satisfactory account of zero can be obtained by integrating an account of numbers as properties of collections, work on the philosophy of absences, and (...) recent work in numerical cognition and ontogenetic studies.

An introduction to contemporary debates in philosophy of perception.

Overview of recent work in philosophy of perception.

The aim of this paper is to argue that it is a promising avenue of research to consider philosophy of perception to be a guide to aesthetics. More precisely, my claim is that many, maybe even most, traditional problems in aesthetics are in fact about philosophy of perception that can, as a result, be fruitfully addressed with the help of the conceptual apparatus of philosophy of perception. This claim may sound provocative, but after qualifying (...) what I mean by aesthetics (to be contrasted with philosophy of art) and by philosophy of perception, it may be easier to accept. (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. (shrink)

In the philosophy of perception, direct realism has come into vogue. Philosophical authors assert and assume that what their readers want, and what anyone should want, is some form of direct realism. There are disagreements over precisely what form this direct realism should take. The majority of positions in favor now offer a direct realism in which objects and their material or physical properties constitute the contents of perception, either because we have an immediate or intuitive acquaintance (...) with those objects and properties, or because our perceptual states have informational content that represents the properties of those objects (and which is not itself an object of perception and has no specifically subjective aspect). This paper considers various forms of perceptual realism, including, for purposes of comparison, the largely abandoned indirect or representative realism. After surveying the variety of perceptual realisms and considering their various commitments, I introduce some considerations concerning the phenomenology of visual space that cause trouble for most forms of direct realism. These considerations pertain to the perception of objects in the distance and, secondarily, to the perception of shapes at a slant. I argue that one of the lesser known varieties of perceptual realism, critical direct realism, can meet the challenges offered by the facts of spatial perception. (shrink)

This dissertation explores several illuminating points of intersection between the philosophy of perception and the philosophy of vagueness. Among other things, I argue: (i) that it is entirely unhelpful to theorize about perception or consciousness using Nagelian "what it's like" talk; (ii) that a popular recent account of perceptual phenomenology (representationalism) conflicts with our best theory of vagueness (supervaluationism); (iii) that there are no vague properties, for Evans-esque reasons; (iv) that it is impossible to insert "determinacy" (...) operators into representationalism in a truth-preserving manner; and (v) that strong versions of dualism are unable to accommodate the possibility of borderline consciousness.

This paper investigates the nature of reality by looking at the philosophical debate between realism and idealism and at scientific investigations in quantum physics and at recent studies of animal senses, neurology and cognitive psychology. The concept of perceptual relativity is examined and this involves looking at sense perception in other animals and various examples of perceptual relativity in science. It will be concluded that the universe is observer dependent and that there is no reality independent of the observer, (...) which is knowable to the observer. The paper concludes by an investigation of what an observer dependent universe would be like and that recognition of an observer dependent world would lead to a more open minded and tolerant world.

In Taber's work, "A Hindu Critique of Buddhist Epistemology," Kumārila tackles the concept of perception in MS 1.1.4 and asserts that perception cannot serve as a means to comprehend Dharma. His argument revolves around the idea that perception apprehends objects in the present, while Dharma's outcomes lie in the future. This distinction holds significance because, according to Kumārila, only the Veda can be a valid means of understanding Dharma. However, I contend that the definition of perception (...) presented in MS 1.1.4 can be a viable method for comprehending Dharma. Kumārila defends the Veda's eternality, resulting in a unique Vedic concept of time that amalgamates past, present, and future into an ever-existing present. Given this perspective, when perception, as defined in MS 1.1.4, apprehends an object in the present, it extends the possibility of grasping the outcomes of Dharma in the future. This is possible because the Vedic conception of time posits an eternal continuum where past, present, and future coexist. Consequently, the proposed definition of perception in MS 1.1.4 can be a legitimate means of gaining knowledge about Dharma. (shrink)

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and (...) which ‘subjective’? What properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

Should we do speculative cognitive science? - In present day philosophy, I see a fashion that uses empirical facts (data) to support positions that are not philosophical but empirical in nature. The argumentative structure is classical philosophy, saying that ‘this has to be that way because …’ where the ‘this’ refers to some empirical state of affairs. This kind of philosophy speculates about empirical facts in areas where we do not yet know the facts – the arguments (...) are a priori, supported by a posteriori data. This is precisely what the speculative philosophy of German Idealism was doing, e.g. in the works of Schelling or Hegel. (shrink)

The article focuses on an unexamined so far aspect of byzantine philosophy, namely the influence of Arabic philosophy upon byzantine thinkers. Despite the vicinity of Byzantium and Arabic territories, the philosophical interactions were minimal. Scholarios claimed, in a dedicatory epistle to Constantine Paleologus (1405-1453), that he had studied the treatises of Avicenna, Averroes, and other Arab and Persian philosophers. He admitted that Averroes was beyond doubt the best commentator of Aristotle. Scholarios acknowledged that the study of the Arabs (...) contributed immensely to his philosophical education and particularly to the proper understanding of the Aristotelian philosophy (Scholarios, vii.1-6). Scholarios aimed at the enrichment and renewal of Byzantine philosophy. Besides his high esteem for Arabic philosophy, he devoted a large part of his life translating and paraphrasing the Scholastics, especially Aquinas. Despite Scolarios’ claim about his erudition on the Arab and Persian philosophers, a detailed examination of his works proves that in most cases he simply reproduced and incorporated sections from Aquinas’ works, without resorting to the original sources. Scholarios’ references to the Arabs are multiplied in his translations and compendia of Aquinas’ works, but are reduced significantly in his original texts. Frequently Scholarios refrained from mentioning the Arab philosophers, despite the fact that he commented on Aquinas’ passages, which are dedicated to Avicenna or Averroes. On the contrary, Scholarios did not avoid mentioning in detail Aquinas’ Christian or ancient Greek sources. It is obvious that Scholarios did not have a consistent approach towards Arabic philosophy. Most of the times he reproduced loosely Aquinas’ passages, where the latter commented on the Arabs. (shrink)

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of (...) evaluative properties as such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

This article considers Helmholtz’s relation to philosophy, including Fichte’s philosophy. Recent interpreters find Fichtean influence on Helmholtz, especially concerning the role of voluntary movement in distinguishing subject from object, or “I” from “not-I.” After examining Helmholtz’s statements about Fichte, the article describes Fichte’s ego-doctrine and asks whether Helmholtz could accept it into his sensory psychology. He could not accept Fichte’s core position, that an intrinsically active I intellectually intuits its own activity and posits the not-I as limiting and (...) determining that activity, because that account requires cognitive abilities that conflict with Helmholtz’s claim that the development of spatial perception relies primarily on associative memory and involves no direct awareness of the ego’s activity as such. Helmholtz would have known various accounts of the distinction between subject and object, or self and world, from sensory physiology, including associative accounts invoking voluntary motor movements and accounts describing checks on the perceiver’s activity. Some of the accounts cite Fichte on the I and not-I, but most do not, and none adopt Fichte’s Idealism. Finally, the article examines Helmholtz’s relation to metaphysics, finding that in all periods he rejected Fichtean Idealism and that the modest metaphysics of his mature period is a version of structural realism.

It seems plausible that visual experiences of darkness have perceptual phenomenal content that clearly differentiates them from absences of visual experiences. I argue, relying on psychological results concerning auditory attention, that the analogous claim is true about auditory experiences of silence. More specifically, I propose that experiences of silence present empty spatial directions like ‘right’ or ‘left’, and so have egocentric spatial content. Furthermore, I claim that such content is genuinely auditory and phenomenal in the sense that one can, in (...) principle, recognize that one is experiencing silence. This position is far from obvious, as the majority of theories concerning silence perception do not ascribe perceptual phenomenal content to experiences of silence. (shrink)

Perception is the ultimate source of our knowledge about contingent facts. It is an extremely important philosophical development that starting in the last quarter of the twentieth century, philosophers have begun to change how they think of perception. The traditional view of perception focussed on sensory receptors; it has become clear, however, that perceptual systems radically transform the output of these receptors, yielding content concerning objects and events in the external world. Adequate understanding of this process requires (...) that we think of perception in new ways—how it operates, the differences among the modalities, and integration of content provided by the individual senses. Philosophers have developed new analytic tools, and opened themselves up to new ways of thinking about the relationship of perception to knowledge. The Oxford Handbook of the Philosophy of Perception is a collection of entries by leading researchers that reviews these new directions in philosophical thought. The Introduction to the Handbook reviews the history of the subject from its beginnings in ancient Greece to the nineteenth century, and the way that science and philosophy have together produced new conceptions during the last hundred years. It shows how the new thinking about perception has led to a complex web of theories. (shrink)

This dissertation aims to revive wave theory in the philosophy of sound. Wave theory identifies sounds with compression waves. Despite its wide acceptance in the scientific community as the default position, many philosophers have rejected wave theory and opted for different versions of distal theory instead. According to this current majority view, a sound has its stationary location at its source. I argue against this and other alternative philosophical theories of sound and develop wave theory into a more defensible (...) form. Philosophers of sound tend to emphasise how sounds are experienced to be in their arguments. Most often, it is assumed that that which appears to be a distally located bearer of auditory properties in an auditory experience is a sound. Chapter 1 argues that if this distal entity is the sound source instead, many of the existing theories of sound will be severely affected. Chapter 2 discusses auditory perception and criticises the common assumption that we hear non-sound entities in virtue of hearing sounds. I show that this assumption begs the question against certain theories of sound and that the contrary view that sound sources can be directly heard is more plausible. If sound sources can be directly heard, then features commonly attributed to sounds based on auditory experiences might rather be features of sound sources. I examine eight of such features in Chapter 3. Only four of them survive. Chapters 4 and 5 review the existing theories of sound. After a taxonomy of existing theories of sound, each theory is criticised one-by-one. Some of them are problematic precisely because they rely on the implausible assumption that that which appears to be distally located in an auditory experience is a sound rather than a sound source. Lastly, Chapter 6 focuses on wave theory. It begins with two positive arguments for wave theory in general, followed by my replies to two common objections in the literature. I then move on to develop my version of wave theory. There are two core aspects of my view. The first one is a metaphysics of compression waves; the second is an account of what it is to hear compression waves. After comparing my view with a similar theory, I demonstrate the explanatory power of my view in two steps. First, the eight commonly accepted features of sounds examined in Chapter 3 are revisited. It turns out that my view can accommodate all of them. Second, explanations for four special sound-related phenomena are offered at the end of the chapter. I conclude in the last chapter with the suggestion that, as a philosopher, the best way to defend wave theory is to offer a better understanding of auditory perception which explains how compression waves are experienced.

The essays in this volume explore those aspects of Kant’s writings which concern issues in the philosophy of mind. These issues are central to any understanding of Kant’s critical philosophy and they bear upon contemporary discussions in the philosophy of mind. Fourteen specially written essays address such questions as: What role does mental processing play in Kant’s account of intuition? What kinds of empirical models can be given of these operations? In what sense, and in what ways, (...) are intuitions object-dependent? How should we understand the nature of the imagination? What is inner sense, and what does it mean to say that time is the form of inner sense? Can we cognize ourselves through inner sense? How do we self-ascribe our beliefs and what role does self-consciousness play in our judgments? Is the will involved in judging? What kind of knowledge can we have of the self ? And what kind of knowledge of the self does Kant proscribe? These essays showcase the depth of Kant’s writings in the philosophy of mind, and the centrality of those writings to his wider philosophical project. Moreover, they show the continued relevance of Kant’s writings to contemporary debates about the nature of mind and self. Contents: 0. Introduction Anil Gomes and Andrew Stephenson 1.

In The Border between Seeing and Thinking, Ned Block argues that the distinction between perception and cognition should be grounded in representational format. I object that cognition is multifaceted, and includes representations with the same format as some perceptual representations. We can save Block’s view by interpreting it as concerning the border between one elite species of cognition—namely, propositional thought—and everything below it, including perception. But that leaves the border between perception and cognition in general unexplained. To (...) fill this gap, I recommend my stimulus-dependence account of the border and reply to objections Block raises against it. This brings into relief a category of mind that is crucial to understanding human infants and nonhuman animals—namely, nonpropositional cognition, which sits between perception and propositional thought.

A recurring theme dominates recent philosophical debates about the nature of conscious perception: naïve realism’s opponents claim that the view is directly contradicted by empirical science. I argue that, despite their current popularity, empirical arguments against naïve realism are fundamentally flawed. The non-empirical premises needed to get from empirical scientific findings to substantive philosophical conclusions are ones the naïve realist is known to reject. Even granting the contentious premises, the empirical findings do not undermine the theory, given its overall (...) philosophical commitments. Thus, contemporary empirical research fails to supply any new argumentative force against naïve realism. I conclude that, as philosophers of mind, we would be better served spending a bit less time trying to wield empirical science as a cudgel against our opponents, and a bit more time working through the implications of each other’s views – something we can accomplish perfectly well from the comfort of our armchairs.

Berkeley’s ‘esse is percipi’ has been criticized for implying epistemological solipsism, the main argument being that different minds cannot harbor numerically one and the same idea. Similarly, C. J. Boström, the dominating Swedish philosopher in the nineteenth century, was early scorned because his principle of esse est percipi allegedly contradicts the simultaneous claim that two spirits can perceive the same thing under qualitatively different appearances. Whereas the criticism against Berkeley is here regarded as valid, it is argued that Boström successfully (...) defended himself by employing a dual concept of meaning, resembling Frege’s Sinn and Bedeutung some thirty years later, and by postulating an ontology that permits human minds to share in the divine ideas that constitute reality.

(Shoshana Smith now goes by her married name, Shoshana Brassfield: http://philpapers.org/profile/37640) Descartes famously claims that everything we perceive clearly and distinctly is true. Although this rule is fundamental to Descartes’s theory of knowledge, readers from Gassendi and Leibniz onward have complained that unless Descartes can say explicitly what clear and distinct perception is, how we know when we have it, and why it cannot be wrong, then the rule is empty. I offer a detailed analysis of clear and distinct (...) perception, showing how Descartes answers these questions. Many doubts about the usefulness of the clarity and distinctness rule arise from the mistaken assumption that in clear and distinct perception, like sense perception, we must be able to establish a correspondence between perception and reality before we can have knowledge. I show that Descartes has a different metaphysical picture of clear and distinct perception. Clear and distinct perception is direct perception, typically of essences. On this view, by relying on the intellect instead of the senses, we can have direct perception not only of our own ideas, but also of a mind-independent reality. Because clear and distinct perception is direct perception, problems of correspondence do not arise. My account of clear and distinct perception also yields unique insight into other issues in Descartes, such as the Cartesian Circle and the doctrine of the free creation of the eternal truths.

Many of Margaret Cavendish’s criticisms of Thomas Hobbes in the Philosophical Letters (1664) relate to the disorder and damage that she holds would result if Hobbesian pressure were the cause of visual perception. In this paper, I argue that her “two men” thought experiment in Letter IV is aimed at a different goal: to show the explanatory potency of her account. First, I connect Cavendish’s view of visual perception as “patterning” to the “two men” thought experiment in Letter (...) IV. Second, I provide a potential reply on Hobbes’s behalf that appeals to physiological differences between perceivers’ sense organs, drawing upon Hobbes’s optics in De homine. Third, I argue that such a reply would misunderstand Cavendish’s objective of showing the limited explanatory resources available in understanding visual perception as pressing when compared to her view of visual perception as patterning.

ABSTRACT The difference between perception and cognition seems introspectively obvious in many cases. Perceiving and thinking have also been assigned quite different roles, in epistemology, in theories of reference and of mental content, in philosophy of psychology, and elsewhere. Yet what is the nature of the distinction? In what way, or ways, do perception and cognition differ? The paper reviews recent work on these questions. Four main respects in which perception and cognition have been held to (...) differ are discussed. First, their phenomenal character, such as the often-remarked vivacity or immediacy of perception. Second, the way in which they represent the world, e.g. the non-propositional nature of the contents, or non-discursive character of the vehicles, that have been held to characterise perceptual representation. Third, their place in cognitive architecture, i.e., roughly, in the information-flow of the mind, such as their alleged (non-)modularity. Fourth, their mind-world relations, e.g. the way in which perceptions seem to be tightly causally linked with distal or proximal stimuli. Against this background, we distinguish some main options for an account of the perception/cognition distinction, in particular concerning whether there is one, several, or no interesting and principled distinction(s) to be drawn here.

[Penultimate draft] I present the perceptualist/representationalist theories of pain in broad outline and critically examine them in light of a competing view according to which awareness of pain is essentially introspective. I end the essay with a positive sketch of a naturalistic proposal according to which pain experiences are intentional but not fully representational. This proposal makes sense of locating pains in body parts as well as taking pains as subjective experiences.

This paper responds to critical commentaries on my book, Perceiving Reality (OUP, 2012), by Laura Guerrero, Matthew MacKenzie, and Anand Vaidya. Guerrero focuses on the metaphysics of causation, and its role in the broader question of whether the ‘two truths’ framework of Buddhist philosophy can be reconciled with the claim that science provides the best account of our experienced world. MacKenzie pursues two related questions: (i) Is reflexive awareness (svasaṃvedana) identical with the subjective pole of a dual-aspect cognition or (...) are there alternative, perhaps better, ways of understanding this self-intimating character of mental states? (ii) Is perception constitutively intentional or is it representational? Vaidya argues that, in so far as Husserlian phenomenology and Buddhism differ in terms of their fundamental ontological commit- ments, they must be incompatible, thus rendering any cross-cultural philosophical project that seeks their rapprochement tenuous. One of my aims in Perceiving Reality is to show how accounts of perception informed by metaphysical realism can be problematic on both metaphysical and epistemological grounds, especially when relying on conceptions of consciousness that ignore its properly phenomenological features.

One very popular framework in contemporary epistemology is Bayesian. The central epistemic state is subjective confidence, or credence. Traditional epistemic states like belief and knowledge tend to be sidelined, or even dispensed with entirely. Credences are often introduced as familiar mental states, merely in need of a special label for the purposes of epistemology. But whether they are implicitly recognized by the folk or posits of a sophisticated scientific psychology, they do not appear to fit well with perception, as (...) is often noted. -/- This paper investigates the tension between probabilistic cognition and non-probabilistic perception. The tension is real, and the solution—to adapt a phrase from Quine and Goodman—is to renounce credences altogether. (shrink)

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes (...) depending on one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

In this paper, I explore Augustine’s account of sense cognition in book 11 of De Trinitate. His discussion in this context focuses on two types of sensory state—what he calls “outer vision” and “inner vision,” respectively. His analysis of both types of state is designed to show that cognitive acts involving external and internal sense faculties are susceptible of a kind of trinitarian analysis. A common way to read De Trin. 11, is to interpret Augustine’s account of “outer” vision as (...) an analysis of sense perception and his account “inner” vision as an analysis of occurrent sensory memory and imagination. I argue against such a reading of De Trin. 11, however. Insofar as we take perception to be a phenomenally conscious mode of sensory awareness, outer vision cannot, I claim, be the equivalent of ordinary sense perception. For, on Augustine’s view, the deliverances of outer vision only reach the threshold of consciousness, when outer vision occurs in conjunction with inner vision. Hence, on my analysis, sense perception turns out to be a complex, hybrid state—one that involves both outer and inner vision. If I am right, acts of sense perception turn out not to be directly susceptible to trinitarian analysis. Even so, the account is interesting and nuanced for all that. (shrink)

The aim of this paper is to outline Dorothy Emmet’s (1904-2000) account of perception in The Nature of Metaphysical Thinking (published in 1945). Emmet’s account of perception is part of a wider attempt to rehabilitate metaphysics in the face of logical positivism and verificationism (of the kind espoused most famously by A. J. Ayer). It is thus part of an attempt to stem the tide of anti-metaphysical thought that had become widespread in British philosophy by the middle (...) of the twentieth century. In pursuit of that aim, Emmet draws on the work of figures like A. N. Whitehead and Henri Bergson, rather than more mainstream analytic thinkers like Bertrand Russell or G. E. Moore, for inspiration. Indeed, Emmet’s ideas stand in contrast to the prevailing tides of British philosophy during her lifetime. This makes Emmet a figure of considerable historical interest; she does not fit neatly into the traditional narrative of the continental-analytic divide, proposed a way forward for metaphysics in one of its greatest times of crisis, and pre-empted certain movements in more contemporary philosophy of perception. By espousing her unique account of perception and drawing out its connections to her wider philosophy, I hope to put Emmet ‘on the map’, so to speak, of twentieth century British thought. (shrink)

One necessary condition on any adequate account of perception is clarity regarding whether unconscious perception exists. The issue is complicated, and the debate is growing in both philosophy and science. In this paper we consider the case for unconscious perception, offering three primary achievements. First, we offer a discussion of the underspecified notion of central coordinating agency, a notion that is critical for arguments that purportedly perceptual states are not attributable to the individual, and thus not (...) genuinely perceptual. We develop an explication of what it is for a representational state to be available to central coordinating agency for guidance of behavior. Second, drawing on this explication, we place a more careful understanding of the attributability of a state to the individual in the context of a range of empirical work on vision-for-action, saccades, and skilled typing. The results place pressure on the skeptic about unconscious perception. Third, reflecting upon broader philosophical themes running through debates about unconscious perception, we highlight how our discussion places pressure on the view that perception is a manifest kind, rather than a natural kind. In doing so, we resist the tempting complaint that the debate about unconscious perception is merely verbal. (shrink)

Auditory perception is traditionally conceived as the perception of sounds — a friend’s voice, a clap of thunder, a minor chord. However, daily life also seems to present us with experiences characterized by the absence of sound — a moment of silence, a gap between thunderclaps, the hush after a musical performance. In these cases, do we positively hear silence? Or do we just fail to hear, and merely judge or infer that it is silent? This longstanding question (...) remains controversial in both the philosophy and science of perception, with prominent theories holding that sounds are the only objects of auditory experience and thus that our encounter with silence is cognitive, not perceptual. However, this debate has largely remained theoretical, without a key empirical test. Here, we introduce a novel empirical approach, presenting experimental evidence that silence can be genuinely perceived (not just cognitively inferred). We ask whether silences can ‘substitute’ for sounds in event-based auditory illusions — empirical signatures of auditory event representation in which auditory events distort perceived duration. Seven experiments introduce three new ‘silence illusions’ — the one-silence-is-more illusion, silence-based warping, and the oddball-silence illusion — each adapted from a prominent perceptual illusion previously thought to arise only from sounds. Subjects were immersed in ambient noise interrupted by silences structurally identical to the sounds in the original illusions. In all cases, silences elicited temporal distortions perfectly analogous to the illusions produced by sounds. Our results suggest that silence is truly heard, not merely inferred, introducing a general approach for studying absence perception. (shrink)

According to a traditional view, there is no categorical difference between the phenomenology of perception and the phenomenology of imagination; the only difference is in degree (of intensity, resolution, etc.) and/or in accompanying beliefs. There is no categorical difference between what it is like to perceive a dog and what it is like to imagine a dog; the former is simply more vivid and/or is accompanied by the belief that a dog is really there. A sustained argument against this (...) traditional view is prosecuted by Sartre, who develops an alternative according to which there is a categorical difference between the two phenomenologies. This paper draws on Sartre’s work in this area to develop a similar account of perception and imagination as categorically different. (shrink)

The Special Theory of Relativity (STR) holds sway as a theory of time due to its apparently successful predictive structure regarding time-related phenomena such as the increased life spans of mesons or retarded clocks on jets circling the globe, and due to the relativization of simultaneity intrinsic to this theoretical structure. Yet the very structure of the theory demands that such very real physical effects be construed as non-ontological. The scope and depth of this contradiction is explored and, if these (...) time-changes are indeed viewed as ontological effects within STR, an additional problem for the theory is introduced in the context of perception. The origins of this confused situation arise as a result of the fact that STR is an expression of a classical, spatial metaphysic – a framework that equally underpins current discussions of the hard problem. This metaphysic holds an inadequate concept of time and a failure to acknowledge the reality of simultaneous causal flows. These problems are developed against the background of an alternative, namely, the temporal metaphysic of Bergson – a framework that provides a profoundly different base for viewing both relativity and consciousness.

Focusing on Descartes’ conclusion in the second Meditation that bodies are strictly perceived through the intellect alone, I contextualize, outline, and elucidate Descartes’ first two Meditations. I begin with a summary of key themes from the first Meditation and outline the reasons for Descartes’ radical doubt. I then provide a detailed explication of Descartes’ argumentitive journey in the second meditation, wherein Descartes arrives at the hypothesis that he is a thinking thing, and demonstrates the plausibility of this hypothesis by scrutinizing (...) a piece of wax until he is able to clearly and distinctly perceive it. I elaborate on Descartes’ conclusion that bodies are perceived through the intellect alone by discussing how abstraction can be used to understand any external body clearly and distinctly, before explaining the overall significance of the conclusion as an affirmation of Descartes’ existence, which gives him profound knowledge of the self.

How do we see the world aright? This question is central to Iris Murdoch’s philosophy as well as to that of her great source of inspiration, Simone Weil. For both of them, not only our action, but the very quality of our being depends on the ability to see things as they are, where vision is both a metaphor for immediate understanding and a literal expression of the requirement to train our perception so as to get rid of (...) illusions. For both, too, the method to achieve this goal is attention. For both, finally, attention requires a dethronement of the self, considered as the source of illusion. In this paper I investigate what moral perception means for each of these philosophers and how it operates through attention and its relationship with the self. I will show that, despite many striking similarities, Murdoch’s project does not equal ‘Weil minus God’, but offers a different concept of the self, a different understanding of its removal, and therefore a different picture of attention and moral perception. In evaluating both views, I will gesture towards a third way represented by Zen Buddhism, which both philosophers variously consider but do not embrace. (shrink)

Traditional accounts of the perception/cognition divide tend to draw it in terms of subpersonal psychological processes, processes into which the subject has no first-person insight. Whatever betides such accounts, there seems to also be some first-personally accessible difference between perception and thought. At least in normal circumstances, naïve subjects can typically tell apart their perceptual states from their cognitive or intellectual ones. What are such subjects picking up on when they do so? This paper is an inconclusive search (...) for an answer. At its end, I conclude, without joy, that we may have to simply accept the perception/cognition distinction as a primitive and inexplicable bright line within the sphere of conscious phenomena.

The possibilities of unconscious perception and unconscious bias prompt parallel debates about unconscious mental content. This chapter argues that claims within these debates alleging the existence of unconscious content are made fraught by ambiguity and confusion with respect to the two central concepts they involve: consciousness and content. Borrowing conceptual resources from the debate about unconscious perception, the chapter distills the two conceptual puzzles concerning each of these notions and establishes philosophical strategies for their resolution. It then argues (...) that empirical evidence for unconscious bias falls victim to these same puzzles, but that progress can be made by adopting similar philosophical strategies. Throughout, the chapter highlights paths forward in both debates, illustrates how they serve as fruitful domains in which to study the relationship between philosophy and empirical science, and uses their combined study to further understanding of a general theory of unconscious content.

In the contemporary discussions concerning unconscious perception it is not uncommon to postulate that content and phenomenal character are ‘orthogonal’, i.e., there is no type of content which is essentially conscious, but instead, every representational content can be either conscious or not. Furthermore, this is not merely treated as a thesis justified by theoretical investigations, but as supported by empirical considerations concerning the actual functioning of the human cognition. In this paper, I address unconscious color perception and argue (...) for a negative thesis—that the main experimental paradigms used in studying unconscious color perception do not provide support for the position that conscious and unconscious color representations have the same type of content. More specifically, I claim that there is no significant support for the claim that unconscious vision categorically represents surface colors. (shrink)

What is the biological function of perception? I hold perception, especially visual perception in humans, has the biological function of accurately representing the environment. Tyler Burge argues this cannot be so in Origins of Objectivity (Oxford, 2010), for accuracy is a semantical relationship and not, as such, a practical matter. Burge also provides a supporting example. I rebut the argument and the example. Accuracy is sometimes also a practical matter if accuracy partly explains how perception contributes (...) to survival and reproduction. (shrink)

What method should we use to determine the nature of perceptual experience? My focus here is the Kantian thought that transcendental arguments can be used to determine the nature of perceptual experience. I set out a dilemma for the use of transcendental arguments in the philosophy of perception, one which turns on a comparison ofthe transcendental method with the first-personal method of early analytic philosophy, and with the empirical methods of much contemporary philosophy of mind. The (...) transcendental method can avoid this dilemma only if it commits to our possessing a capacity for imaginative reflection, one which is capable of identifying certain formal properties of experience.This result indicates some of the commitments which must be made if transcendental arguments are to be used in the philosophy of perception, and it has implications for those views that take the philosophy of perception to be autonomous of the empirical science of perception.

Extensive and critical review of Perception and Reality in Kant, Husserl and McDowell, written by van Mazijk, Corijn focussing on his discussion of McDowell.

According to the increasingly popular perceptual/representational accounts of pain (and other bodily sensations such as itches, tickles, orgasms, etc.), feeling pain in a body region is perceiving a non-mental property or some objective condition of that region, typically equated with some sort of (actual or potential) tissue damage. In what follows I argue that given a natural understanding of what sensory perception requires and how it is integrated with (dedicated) conceptual systems, these accounts are mistaken. I will also examine (...) the relationship between perceptual views and two (weak and strong) forms of representationalism about experience. I will argue that pains pose very serious problems for strong representationalism as well. (shrink)

Perception is typically distinguished from cognition. For example, seeing is importantly different from believing. And while what one sees clearly influences what one thinks, it is debatable whether what one believes and otherwise thinks can influence, in some direct and non-trivial way, what one sees. The latter possible relation is the cognitive penetration of perception. Cognitive penetration, if it occurs, has implications for philosophy of science, epistemology, philosophy of mind, and cognitive science. This paper offers an (...) analysis of the phenomenon, its theoretical consequences, and a variety of experimental results and possible interpretations of them. The paper concludes by proposing some constraints for analyses and definitions of cognitive penetrability. (shrink)

A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition (...) of chapter summaries, suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.
