This thesis is a defense of the Content View on perceptual experience, of the idea that our perceptual experiences represent the world as being a certain way and so have representational content. Three main issues are addressed in this work. Firstly, I try to show that the Content View fits very well both with the logical behaviour of ordinary ascriptions of seeing-episodes and related experiential episodes, and with our pretheoretical intuitions about what perceiving and experiencing ultimately (...) are: that preliminary analysis speaks for the prima facie plausibility of such a view. Secondly, I put forward a detailed account of perceptual episodes in semantic terms, by articulating and arguing for a specific version of the Content View. I provide arguments for the following theses: Perceptual content is two-layered so it involves an iconic level and a discrete or proto-propositional level. Perceptual content is singular and object-dependent or de re, so it includes environmental objects as its semantic constituents. The phenomenal character of perceptual experience is co-determined by the represented properties together with the Mode, but not by the perceived objects: that is what I call an impure representationalism. Perceptual content is 'Russellian': it consists of worldly objects, properties and relations. Both perceptual content and phenomenal character are 'wide' or determined by environmental factors, thus there is no Fregean, narrow perceptual content. Thirdly, I show that such a version of the Content View can cope with the objections which are typically moved against the Content View as such by the advocates of disjunctivism. I myself put forward a moderately disjunctivist version of the Content View, according to which perceptual relations must be told apart from hallucinations as mental states of a different kind. Such a disjunctivism is 'moderate' insofar as it allows genuinely relational perceptual experiences and hallucinations to share a positive phenomenal character, contrary to what Radical Disjunctivism cum Naïve Realism holds. Showing that the Content View vindicates our pre-theoretical intuitions and does justice of our ordinary ascriptive practices, articulating a detailed and argued version of the Content View, and showing that such a version is not vulnerable to the standard objections recently moved to the Content View by the disjunctive part, all that can be considered as a big, multifaceted Argument for the Content View.

In the philosophy of perception, representationalism is the view that all phenomenological differences among mental states are representational differences, in other words, differences in content. In this paper I defend an alternative view which I call external sortalism, inspired by traditional adverbialism, and according to which experiences are not essentially representational. The central idea is that the external world serves as a model for sorting, conceptualizing, and reasoning surrogatively about perceptual experience. On external sortalism, contents are (...) construed as a kind of gloss on experiences themselves. We can retain what is attractive about representationalism, namely, that perceptual experiences can be evaluated for accuracy, without problematic commitment to the idea that they bear a substantive, representational relation to external objects and properties and that this relation determines the phenomenal character of experience. (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.

In this book, Brit Brogaard defends the view that visual experience is like belief in having a representational content. Her defense differs from most previous defenses of this view in that it begins by looking at the language of ordinary speech. She provides a linguistic analysis of what we say when we say that things look a certain way or that the world appears to us to be a certain way. She then argues that this analysis can be (...) used to argue for the view that visual experience has a representation content that mediates between you and the world when you visually perceive. (shrink)

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are (...) still to be favoured over the perceptual confidence view. (shrink)

For the purpose of this paper, I take it for granted that subjectivity is an essential character of perceptual experience. What I take issue with is the further claim that subjectivity of experience tends to support the view that phenomenal characters are intrinsic properties of experience. A criticism of the claim can be presented from the perspective of representationalism according to which phenomenal character is a kind of representational character. But representationalism fails to do justice (...) to the fact that from the subjective point of view, we seem to be directly aware of mind-independent objects in the world. A stronger criticism canbe based on the disjunctivist’s view of experience that best accommodates direct awareness of the external world. But disjunctivism rejects the common kind that also seems from the subject’s point of view to be shared by veridical perception and hallucination. The crucial problem is whether disjunctivists can make sense of the phenomenology of hallucination. Focusing the discussion on Martin’s epistemic version of disjunctivism, I hope to show the relevance of solving this problem for a better understanding of the subjectivity of experience. (shrink)

Perceptual experiences inform us about objective properties of things in our environment. But they also have perspectival character in the sense that they differ phenomenally when objects are viewed from different points of view. Contemporary representationalists hold, at a minimum, that phenomenal character supervenes on representational content. Thus, in order to account for perspectival character, they need to indentify a type of representational content that changes in appropriate ways with the perceiver’s point of view. Many representationlists, including (...) Shoemaker and Lycan, argue that such contents are best construed in terms of mind-dependent properties. Other representationalists, including Tye and Dretske, hold that these contents involve only mind-independent properties. Susanna Schellenberg has recently developed an account of perceptual experience that would serve these latter representationalists extremely well. She suggests that we can do justice to the perspectival character of perceptual experience by appeal to representations of a certain type of relational properties, so-called ‘situation-dependent properties.’ In this paper, I critically engage with Schellenberg’s proposal in order to show how mind-independent representationalists can explain perspectival character. I argue that appeal to situation-dependent properties is problematic. I then show that mind-independent representationalists can account for perspectical character by means of scenario contents in Christopher Peacocke’s sense. (shrink)

In this paper I begin by considering Travis’s main argument against a representational view of experience. I argue that the argument succeeds in showing that representation is not essential to experience. However, I argue that it does not succeed in showing that representation is not an essential component of experience enjoyed by creatures like us. I then provide a new argument for thinking that the perceptual experience of earthly creatures is representational. The view (...) that ensues is compatible with a certain relational view of experience but entails a rejection of representationalism. (shrink)

This is a chapter from my introductory book *Perception* covering the representational view of experience. I use the Ramsey-Lewis method to define the theoretical term "experiential representation". I clarify and discuss various questions for representationalists, for instance, "how rich is the content of experience?" and "is the content of visual experience singular or general?" Finally, I address some objections to representationalism - in particular, that it cannot explain perceptual presence (John Campbell), and that it cannot (...) explain the "laws of appearance" (constraints on how things can appear). (shrink)

I open my eyes and see that the lemon before me is yellow. States like this—states of seeing that $p$ —appear to be visual perceptual states, in some sense. They also appear to be propositional attitudes (and so states with propositional representational contents). It might seem, then, like a view of perceptual experience on which experiences have propositional representational contents—a Propositional View—has to be the correct sort of view for states of seeing that $p$ . (...) And thus we can’t sustain fully general non-Propositional but Representational, or Relational Views of experience. But despite what we might initially be inclined to think when reflecting upon the apparent features of states of seeing that $p$ , a non-propositional view of seeing that $p$ is, I argue, perfectly intelligible.

The goal of this piece is to put some pressure on Brian O’Shaughnessy’s claim that perceptual experiences are necessarily mental processes. The author targets two motivations behind the development of that view. First, O’Shaughnessy resorts to pure conceptual analysis to argue that perceptual experiences are processes. The author argues that this line of reasoning is inconclusive. Secondly, he repeatedly invokes a thought experiment concerning the total freeze of a subject’s experiential life. Even if this case is coherent, however, (...) it does not show that perceptual experiences are processes. (shrink)

The debate about direct perception encompasses different topics, one of which concerns the richness of the contents of perceptual experiences. Can we directly perceive only low-level properties, like edges, colors etc., or can we perceive high-level properties and entities as well? The aim of the paper is to defend the claim that the content of our perceptual experience can include emotions and also person impressions. Using these examples, an argument is developed to defend a liberal-content view for (...) core examples of social cognition. This view is developed and contrasted with accounts which claim that in the case of registering another person’s emotion while seeing them, we have to describe the relevant content not as the content of a perceptual experience, but of a perceptual belief. The paper defends the view that perceptual experiences can have a rich content yet remain separable from beliefs formed on the basis of the experience. How liberal and enriched the content of a perceptual experience is will depend upon the expertise a person has developed in the field. This is supported by the argument that perceptual experiences can be systematically enriched by perceiving affordances of objects, by pattern recognition or by top-down processes, as analyzed by processes of cognitive penetration or predictive coding.

This paper aims to offer a new metaphysical view of both the representational content and the phenomenal or conscious character of visual experience inspired by Kaplan’s semantics of demonstratives. In Kaplan’s famous account, the character or meaning of a demonstrative type is understood as the function of a particular token of that type (vehicle of content) in the context of the demonstration of the singular content in the context in question. By way of analogy, I want to suggest (...) that the phenomenal character of experience can be best modeled as a function from tokens of experience in the context of experiential contact to their singular contents: that is, the instantiation of properties with which the subject is in experiential contact in those contexts. Since the meaning of demonstratives can also be described by its token-reflexive rule (the object demonstrated by this token demonstrative in this context of demonstration), we can also think of the phenomenal character as a token-reflexive property of representing whatever is normally causally responsible for this token experience in the context of experiential contact. This is what I call Reflexionism, inspired by Tye’s Kaplanianism (Tye 2009, 113-4, 2014). For example, phenomenal yellowness is the token-reflexive property of representing whatever is causally responsible for the relevant brain pattern in the context of experiential contact under normal conditions.

Philosophers have often argued that ascriptions of content are appropriate only to the personal level states of folk psychology. Against this, this paper defends the view that the familiar propositional attitudes and states defined over them are part of a larger set of cognitive proceses that do not make constitutive reference to concept possession. It does this by showing that states with nonconceptual content exist both in perceptual experience and in subpersonal information-processing systems. What makes these states content-involving (...) is their satisfaction of certain basic conditions deriving from a general account of representation-driven behaviour that is neutral on the question of concept possession. It is also argued that creatures can be in states with nonconceptual content even though they possess no conceptual abilities at all. (shrink)

David Papineau develops a new argument against representationalism, centering on the idea that sensory experiences are essentially representational on this view. He defends his own “qualitative view” according to which sensory experiences are only contingently representational. I discuss his main argument against essentialist representationalism and then provide two challenges for his positive account. First, Papineau's theory faces a dilemma when it comes to explaining the contents of our perceptual beliefs in situations where the conscious character of sensory (...) experience comes apart from what it represents. Second, we may need to abandon the idea that sensory experiences are assessable for veridicality. (shrink)

Many philosophers have held that perceptual experience is fundamentally a matter of perceivers being in particular representational states. Such states are said to have representational content, i.e. accuracy or veridicality conditions, capturing the way that things, according to that experience, appear to be. In this thesis I argue that the case against representationalism — the view that perceptual experience is fundamentally and irreducibly representational — that is set out in Charles Travis’s ‘The (...) Silence of the Senses’ (2004) constitutes a powerful, but much misunderstood and neglected argument against this prevailing philosophical orthodoxy. -/- In chapter 2, I present an interpretation of Travis’s arguments that poses a dilemma for the representationalist concerning the indeterminacy and availability of perceptual content. Chapters 3 and 4 evaluate a variety of arguments in favour of such content based upon the nature of appearances, or ‘looks’, including those by Byrne (2009), Siegel (2010) and Schellenberg (2011b), each of which I find to be problematic. Finally, chapters 5 and 6 examine the relationship between representational content and phenomenal character, i.e. what perceptual experience is subjectively like, outlining some potential responses to Travis’s anti-representationalism. These include the external individuation of content and self-knowledge, and the operation of perceptual discriminatory capacities (the latter of which does not necessarily favour a representationalist account of experience). -/- I conclude that Travis’s arguments establish substantive constraints upon the nature and role of perceptual content. Moreover, I argue that the debate centres less upon the existence of such content than its explanatory role, particularly in relation to phenomenal character and the contents of other mental states: belief, intention, thought, knowledge, and so on. This in turn highlights the need for representationalists to better clarify the role of the contents their theories posit, and why such theories constitute a better explanation of the relevant phenomena than the corresponding non-representational view..

The Gestalt principle of isomorphism reveals the primacy of subjective experience as a valid source of evidence for the information encoded neurophysiologically. This theory invalidates the abstractionist view that the neurophysiological representation can be of lower dimensionality than the percept to which it gives rise.

The World In Your Head: A Gestalt View of the Mechanism of Conscious Experience represents a bold assault on one of the greatest unsolved mysteries in science: the nature of consciousness and the human mind. Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain. Through this analysis, the first and most obvious (...) observation is that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. Therefore, the world we see around us is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact, the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is somewhat like a guided hallucination, based on sensory stimulation. This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, and motor control and behavior. It also has implications to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time--apparent in those aesthetic domains--reflect the periodic basis set of the underlying harmonic resonance representation in the brain.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of (...) shape discriminability, apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

A common view in the philosophy of perception holds that states of seeing objects face to face have particular contents. When you see, say, a dog face to face, your visual state represents the particular dog that is in front of you. In this paper, I argue for a related claim about states of seeing objects in conventional photographs. When you see a dog in a photograph, for example, your visual state represents the particular dog that was in front of (...) the camera when the photograph was taken, that is, the photograph's depictum. The argument in this paper proceeds in two steps. In the first step, I discuss states of seeing objects face to face. I argue that such a state represents the particular object whose surface is responsible for the optical information that the visual system uses to construct the state's attributive representational content. In the second step, I apply the result of this discussion to states of seeing objects in photographs. I argue that a state of seeing an object in a photograph has a particular content that represents the object that was in front of the camera when the photograph was taken. (shrink)

Although our subjective impression is of a richly detailed visual world, numerous empirical results suggest that the amount of visual information observers can perceive and remember at any given moment is limited. How can our subjective impressions be reconciled with these objective observations? Here, we answer this question by arguing that, although we see more than the handful of objects, claimed by prominent models of visual attention and working memory, we still see far less than we think we do. Taken (...) together, we argue that these considerations resolve the apparent conflict between our subjective impressions and empirical data on visual capacity, while also illuminating the nature of the representations underlying perceptual experience.

Perception is said to have assertoric force: It inclines the perceiver to believe its content. In contrast, perceptual imagination is commonly taken to be non-assertoric: Imagining winning a piano contest does not incline the imaginer to believe they actually won. However, abundant evidence from clinical and experimental psychology shows that imagination influences attitudes and behavior in ways similar to perceptual experiences. To account for these phenomena, I propose that perceptual imaginings have implicit assertoric force and put forth (...) a theory—the Prima Facie View—as a unified explanation for the empirical findings reviewed. According to this view, mental images are treated as percepts in operations involving associative memory. Finally, I address alternative explanations that could account for the reviewed empirical evidence—such as a Spinozian model of belief formation or Gendler’s notion of alief—as well as potential objections to the Prima Facie View.

Much of the philosophical work on perception has focused on vision, with very little discussion of the chemical senses—olfaction and gustation. In this paper, I consider the challenge that olfactory experience presents to upholding a representational view of the sense modalities. Given the phenomenology of olfactory experience, it is difficult to see what a representational view of it would be like. Olfaction, then, presents an important challenge for representational theories to overcome. In this paper, I (...) take on this challenge and argue for a representational account of olfactory experience that honors its phenomenology. (shrink)

According to a traditional view, perceptual experiences are composites of distinct sensory and cognitive components. This dual-component theory has many benefits; in particular, it purports to offer a way forward in the debate over what kinds of properties perceptual experiences represent. On this kind of view, the issue reduces to the questions of what the sensory and cognitive components respectively represent. Here, I focus on the former topic. I propose a theory of the contents of the sensory aspects (...) of perceptual experience that provides clear criteria for identifying what kinds of properties they represent. (shrink)

According to a traditional Cartesian view of the mind, you have a privileged access to your own conscious experiences that nobody else can have. Therefore, you have more authority than anybody else on your own experiences. Perceptual experiences are selfintimating: you are aware of what you are consciously perceiving. If you report seeing a pink elephant, nobody is entitled to deny it. There may be no pink elephant, but you do have the conscious experience of such elephant. However, (...) the progress in brain imaging might lead to the possibility that the scientist knows as well as you – or even better than you – what you are seeing, and even what you are hallucinating. What was only a thought experiment fourty years ago has become reality. Does brain reading challenge the privacy of the mind? Who has the most authority on your mind in case of conflict? You or the brain scientist? (shrink)

Two universal functional principles of Grossberg’s Adaptive Resonance Theory decipher the brain code of all biological learning and adaptive intelligence. Low-level representations of multisensory stimuli in their immediate environmental context are formed on the basis of bottom-up activation and under the control of top-down matching rules that integrate high-level, long-term traces of contextual configuration. These universal coding principles lead to the establishment of lasting brain signatures of perceptual experience in all living species, from aplysiae to primates. They are (...) re-visited in this concept paper on the basis of examples drawn from the original code and from some of the most recent related empirical findings on contextual modulation in the brain, highlighting the potential of Grossberg’s pioneering insights and groundbreaking theoretical work for intelligent solutions in the domain of developmental and cognitive robotics.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that (...) to perceive is to represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

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

Realism concerning a given domain of things is the view that the things in that domain exist, and are as they are, quite independently of anyone.

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)

This is not surprising, given that vision holds for us a certain prestige. Our visual experience is incredibly rich, offering up a (...) mosaic of apparent three-dimensional objects. For this reason, it is commonplace to suppose that visual experience is world-directed, with the view taking its most popular form in the representational, or content, view. World-directed views contrast with what we might call subjectivist views — views according to which experiences are raw feels or mere sensations. (shrink)

In this paper I argue that the representational theory of perception, on which the world is represented as being a certain way in perceptual experience, cannot explain how there can be a genuinely epistemic connection between experience and belief. I try to show that we are positively required to deny that perceptual consciousness is contentful if we want to make its fitness for epistemic duties intelligible. (So versions of the representational theory on which (...) class='Hi'>experience has a merely causal purchase on belief are not considered.) But my aim is not just negative. I try to defeat representationalism in such a way as to motivate a robustly presentational theory of perception. According to such a theory, perceptions are relations not between a subject and a content but between a subject and an ordinary object (such that if the relation holds at t, an appropriate subject and object must exist at t, and the object must be presented to the subject). I end by sketching an account of perceptual experience that is meant to show that, contrary to a very popular misconception, there is a way to conceive perceptual consciousness as relational and presentational (not intentional and representational) that does not succumb to the celebrated ?myth of the Given?

Much research on color representation and categorization has assumed that relations among color terms can be proxies for relations among color percepts. We test this assumption by comparing the mapping of color words with color appearances among different observer groups performing cognitive tasks: an invariance of naming task; and triad similarity judgments of color term and color appearance stimuli within and across color categories. Observer subgroups were defined by perceptual phenotype and photopigment opsin genotype analyses. Results suggest that individuals (...) rely on at least two different representational models of color experience: one lexical, conforming to the culture's normative linguistic representation, and another individual perceptual representation organizing each observer's color sensation experiences. Additional observer subgroup analyses suggest that perceptual phenotype variation within a language group may play a greater role in the shared color naming system than previously thought. A reexamination of color naming data in view of these findings may reveal influences on color naming important to current theories. (shrink)

The present paradigm involved manipulating the congruency of the perceptual processing during the study and test phases of a recognition memory task. During each trial, a gaze-contingent window was used to limit the stimulus display to a region either inside or outside a 108 square centred on the participant’s point of gaze, constituting the Central and Peripheral viewing modes respectively. The window position changed in real time in concert with changes in gaze position. Four experiments documented better task performance (...) when viewing modes at encoding and retrieval matched than when they mismatched (i.e., perceptual specificity effects). Viewing mode congruency effects were demonstrated with both verbal and non-verbal stimuli. The present research is motivated and discussed in terms of theoretical views proposed in the 1970s including the levels-of-processing framework and the proceduralist viewpoint. In addition, implications for current processing and multiple systems views of memory are outlined. (shrink)

This paper defends a dynamic model of the way in which perception is integrated with action, a model I refer to as ‘the navigational account’. According to this account, employing vision and other forms of distance perception, a creature acquires information about its surroundings via the senses, information that enables it to select and navigate routes through its environment, so as to attain objects that satisfy its needs. This form of perceptually guided activity should be distinguished from other kinds of (...) semi-automatic responses to visual stimuli that do not necessarily involve conscious experiences. It essentially involves inner states, which involve both the awareness of phenomenal qualities, and also a representational component. The navigational account is compared here with the enactive approach to perception, which opposes the view that perceptual experiences are inner states. This paper argues that a full account of perception raises a number of different questions. One central explanatory project concerns questions about the kinds of processes that currently enable a creature to identify and respond appropriately to distant objects: the answer, it is argued, lies in acknowledging the role of conscious inner representations in guiding navigational behaviour through complex environments. The fact that perception and action are interdependent does not conflict with the claim that inner representational states comprise an essential stage in visual processing. (shrink)

Representationalists hold that the phenomenal character of a perceptual experience is identical with, or supervenes on, an aspect of its representational content. As such, representationalism could be disproved by a counter-example consisting of two experiences that have the same representational content but differ in phenomenal character. In this paper, I discuss two recently proposed counter-examples to representationalism that involve ambiguous or reversible figures. I pursue two goals. My first, and most important, goal is to show that (...) the representationalist can offer plausible responses to both counter-examples. My second goal is to show the implications of these responses for the nature of the spatial representational contents of perceptual experiences. (shrink)

This is a chapter from my book Perception (Routledge). I explain the physical state view of sensory experience (Papineau, McLaughlin, others). I criticize an argument against it based on the "transparency observation". Then I develop two alternative arguments against it. The first is a Leibniz's Law argument based on the essentially externally directed character of some experiences. The second concerns "brains in vats". Finally I consider a recent response due to David Papineau, which involves rejecting essential external directedness.

All non-relational views of perceptual experience face Jackson's famous many-property problem. I argue that the original problem, and the existing responses to it, have focused too closely on the controversial terminology for which adverbialism is best known. We can also direct Jackson's many-property problem explicitly onto the adverbialist's metaphysics, generating a new challenge. The responses contemporary adverbialists and non-relationalists have made to the original objection are not successful against this challenge. We need a new non-relational account. I (...) sketch an outline of a new theory, and motivate the view by explaining how it can respond successfully to this additional challenge. -/- . (shrink)

From the mystical experiences of religious visions to the most degenerate forms of violence and pornography, the image, be it perceptual or conceptual, has imposed itself as a powerful form of human expression. The evocative, emotional and communicative power of images has been at the centre of a complex, often conflictual relationship in different societies, between exterior and internal forms of representation. Western history has passed alternately through periods of iconophilia and iconophobia, while various cultures have accorded different significance (...) to the capacity of vision to express and reinforce both the ideological and the political sphere. Referring to various examples, the article suggests that the pervasive presence of vision, far from being a self-evident, given element, is at the core of a problematic work of interpretation within the cultural contexts of societies. What appears to the eye can be considered the mirror of true reality or, alternatively, an ambiguous and superficial representation of it, in a dialectic confrontation between the iconic and the mental.

The sensorimotor theory is an influential, non-mainstream account of perception and perceptual consciousness intended to improve in various ways on orthodox theories. It is often taken to be a variety of enactivism, and in common with enactivist cognitive science more generally, it de-emphasises the theoretical role played by internal representation and other purely neural processes, giving theoretical pride of place instead to interactive engagements between the brain, non-neural body and outside environment. In addition to offering a distinctive account of (...) the processing that underlies perceptual consciousness, the sensorimotor theory aims to offer a new and improved account the logical and phenomenological character of perceptual experience, and the relation between physical and phenomenal states. Since its inception in a 2001 paper by O’Regan and Noë, the theory has prompted a good deal of increasingly prominent theoretical and practical work in cognitive science, as well as a large body of secondary literature in philosophy of cognitive science and philosophy of perception. In spite of its influential character, many of the theory’s most basic tenets are incompletely or ambiguously defined, and it has attracted a number of prominent objections. This thesis aims to clarify the conceptual foundations of the sensorimotor theory, including the key theoretical concepts of sensorimotor contingency, sensorimotor mastery, and presence-as-access, and defends a particular understanding of the respective theoretical roles of internal representation and behavioural capacities. In so doing, the thesis aims to highlight the sensorimotor theory’s virtues and defend it from some leading criticisms, with particular attention to a response by Clark which claims that perception and perceptual experience plausibly depend on the activation of representations which are not intimately involved in bodily engagements between the agent and environment. A final part of the thesis offers a sensorimotor account of the experience of temporally extended events, and shows how with reference to this we can better understand object experience. (shrink)

Interpretations abound about Husserl’s understanding of the relationship between veridical perceptual experience and hallucination. Some read him as taking the two to share the same distinctive essential nature, like contemporary conjunctivists. Others find in Husserl grounds for taking the two to fall into basically distinct categories of experience, like disjunctivists. There is ground for skepticism, however, about whether Husserl’s view could possibly fall under either of these headings. Husserl, on the one hand, operates under the auspices of (...) the phenomenological reduction, abstaining from use of any epistemic commitments about mind-transcendent reality, whereas conjunctive and disjunctive accounts of perceptual experience, on the other hand, are both premised on some form of metaphysical realism. There seems to be a basic incompatibility between the former approach and the latter. I examine this line of thinking and argue that the incompatibility is only apparent. (shrink)

Most internalist views hold that experience provides evidential justification for perceptual belief, although there are different ideas about how experience is able to provide this justification. Evidentialism holds that experiences can act as evidence for belief without having propositional content, while dogmatism holds that only an experience with the content that p can provide prima facie justification for the belief that p. I argue that both views succumb to a version of the well-known Sellarsian (...) dilemma: it’s entirely unclear how an experience could act as evidence for belief without having propositional content, and it is ad hoc to claim that experiences with propositional content can act as evidence for belief without explaining why these experiences need not be justified themselves. The way out of the dilemma lies in accepting the non-evidential nature of perceptual experience. (shrink)

Forthcoming (2011) in K. Hawley and F. Macpherson (eds.) The Admissible Contents of Experience, Wiley‐Blackwell. The Admissible Contents of Experience Fiona Macpherson This essay provides an overview of the debate concerning the admissible contents of experience, together with an introduction to the papers in this volume. The debate is one that takes place among advocates of a certain way of thinking of perceptual experiences: that they are states that represent the world. For to say that a (...) state has content is to say that it represents; and its content is usually taken to be that which is represented. One should not be tempted to think that the debate is therefore marginal or esoteric, for this view of perceptual experience has been by far the dominant view of perceptual experience in recent years in philosophy (and in psychology and neuroscience). The debate is about what answer to give to a fundamental question about the nature of perceptual experience, namely: what objects and properties can it represent? (shrink)

Does the material basis of conscious experience extend beyond the boundaries of the brain and central nervous system? In Clark 2009 I reviewed a number of ‘enactivist’ arguments for such a view and found none of them compelling. Ward (2012) rejects my analysis on the grounds that the enactivist deploys an essentially world-involving concept of experience that transforms the argumentative landscape in a way that makes the enactivist conclusion inescapable. I present an alternative (prediction-and-generative-model-based) account that neatly accommodates (...) all the positive evidence that Ward cites on behalf of this enactivist conception, and that (I argue) makes richer and more satisfying contact with the full sweep of human experience.

According to an influential variety of the representational view of perceptual experience—the singular content view—the contents of perceptual experiences include singular propositions partly composed of the particular physical object a given experience is about or of. The singular content view faces well-known difficulties accommodating hallucinations; I maintain that there is also an analogue of Frege's puzzle that poses a significant problem for this view. In fact, I believe that this puzzle presents difficulties for the theory (...) that are unique to perception in that strategies that have been developed to respond to Frege's puzzle in the case of belief cannot be employed successfully in the case of perception. Ultimately, I maintain that this perceptual analogue of Frege's puzzle provides a compelling reason to reject the singular content view of perceptual experience. (shrink)
