Abstract: Abstract: In Mind and World , McDowell conceives of the content of perceptual experiences as conceptual. This picture is supposed to provide a therapy for skepticism, by showing that empirical thinking is objectively and normatively constrained. The paper offers a reconstruction of McDowell's view and shows that the therapy fails. This claim is based on three arguments: 1) the identity conception of truth he exploits is unable to sustain the idea that perception-judgment transitions are normally truth conducing; 2) it could be plausible only from an externalist point of view that is in tension with the view of normativity that motivates conceptualism; 3) the identity conception of truth is incompatible with McDowell's recent version of conceptualism in terms of 'non-propositional intuitive contents'

Abstract: The essay is critically examines the conceptual problems with the influential modularity model of mind. We shall see that one of the essential characters of modules, namely informational encapsulation, is not only inessential, it ties a knot at a crucial place blocking the solution to the problem of understanding the formation of concepts from percepts (nodes of procedural knowledge). Subsequently I propose that concept formation takes place by modulation of modules leading to cross-representations, which were otherwise prevented by encapsulation. It must be noted that the argument is not against modular architecture, but a variety of an architecture that prevents interaction among modules. This is followed by a brief argument demonstrating that module without modularization, i.e. without developmental history, is impossible. Finally the emerging picture of cognitive development is drawn in the form of the layers in the fabric of mind, with a brief statement of the possible implications.

Abstract: This book offers a comprehensive and broadly rationalist theory of the mind which continually tests itself against experimental results and clinical data. Taking issue with Empiricists who believe that all knowledge arises from experience and that perception is a non-cognitive state, Norton Nelkin argues that perception is cognitive, constructive, and proposition-like. Further, as against Externalists who believe that our thoughts have meaning only insofar as they advert to the world outside our minds, he argues that meaning is determined 'in the head'. Finally, he offers an account of how we acquire some of our most basic concepts, including the concept of the self and that of other minds

Abstract: The world shows up to perceptual consciousness in virtue of the deployment of distinct sensorimotor and also conceptual skills. The availability of the world to thought is, in contrast, to be explained in connection with the different sorts of skills put to work in thought. I show that thought and experience are varieties of skilful access to the world. The aim of the paper is to present the outlines of a general theory of access

Abstract: Philosophy, from the earliest times, has made greater claims, and achieved fewer results, than any other branch of learning. In Our Knowledge of the External World , Bertrand Russell illustrates instances where the claims of philosophers have been excessive, and examines why their achievements have not been greater

Abstract: Pylyshyn's target article argues that perception is not inferential, but this is true only under a narrow construal of inference. A more general construal is possible, and has been used to provide formal theories of many visual capacities. This approach also makes clear that the evolution of natural constraints need not converge to the “veridical” state of the world

Abstract: Sense-data, if they exist, could conceivably provide foundations for empirical knowledge. Those who are opposed to empirical foundationalism are therefore also prone to reject sense-data and arguments for their existence, e.g., Rorty, Bonjour; while foundationalists are prone to accept the existence of sense-data, e.g., Russell, Ayer, Broad, Price, Lewis. An exception to this is the position of Roderick Chisholm who accepts empirical foundationalism but rejects the existence of sense-data

Abstract: Suppose you are presented with three red objects. You are then asked to take a careful look at each possible pair of objects, and to decide whether or not their members look chromatically the same. You carry out the instructions thoroughly, and the following propositions sum up the results of your empirical investigation:

i. red object #1 looks the same in colour as red object #2.

ii. red object #2 looks the same in colour as red object #3

Abstract: We are confident of many of the judgements we make as to what sorts of alterations the members of nature's kinds can survive, and what sorts of events mark the ends of their existences. But is our confidence based on empirical observation of nature's kinds and their members? Conventionalists deny that we can learn empirically which properties are essential to the members of nature's kinds. Judgements of sameness in kind between members, and of numerical sameness of a member across time, merely project our conventions of individuation. Our confidence is warranted because apart from those conventions there are no phenomena of kind-sameness or of numerical sameness across time. There is just 'stuff' displaying properties. This paper argues that conventionalists can assign no properties to the 'stuff' beyond immediate phenomenal properties. Consequently they cannot explain how each of us comes to be able to wield 'our conventions'

Abstract: This article simply provides a very short introduction, aimed at non-philosophers, to the time-lag argument for the representational theory of perception.

Abstract: The construction and analysis of arguments supposedly are a philosopher's main business, the demonstration of truth or refutation of falsehood his principal aim. In Sense and Sensibilia, J.L. Austin does something entirely different: He discusses the sense-datum doctrine of perception, with the aim not of refuting it but of 'dissolving' the 'philosophical worry' it induces in its champions. To this end, he 'exposes' their 'concealed motives', without addressing their stated reasons. The paper explains where and why this at first sight outrageous aim and approach are perfectly sensible, how exactly Austin proceeds, and how his approach can be taken further. This shows Austin to be a pioneer of the currently much discussed notion of philosophy as therapy, reveals a subtle and unfamiliar use of linguistic analysis that is not open to the standard objections to ordinary language philosophy, and yields a novel and forceful treatment of the sense-datum doctrine

Abstract: In this paper, I present a version of a sense-data approach to perception, which differs to a certain extent from well-known versions like the one put forward by Jackson. I compare the sense-data view to the currently most popular alternative theories of perception, the so-called Theory of Appearing (a very specific form of disjunctivist approaches) on the one hand and reductive representationalist approaches on the other. I defend the sense-data approach on the basis that it improves substantially on those alternative theories

Abstract: I interpret the anti-idealist manoeuverings of the second half of Moore's 'The refutation of idealism', material as widely cited for its discussion of 'transparency' and 'diaphanousness' as it is deeply obscure. The centerpiece of these manoeuverings is a phenomenological argument for a relational view of perceptual phenomenal character, on which, roughly, 'that which makes the sensation of blue a mental fact' is a non-intentional relation of conscious awareness, a view close to the opposite of the most characteristic contemporary view going under the transparency rubric. The discussion of transparency and diaphanousness is a sidelight, its principal purpose to shore up the main line of argumentation against criticism; in those passages all Moore argues is that the relation of conscious awareness is not transparent, while acknowledging that it can seem to be.

Abstract: When John Langshaw Austin died in ???? he had published only seven papers, together with a translation into English of Frege

Abstract: Shortly before G. E. Moore wrote down the formative for the early analytic philosophy lectures on Some Main Problems of Philosophy (1910–1911), he had become acquainted with two books which influenced his thought: (1) a book by Husserl's pupil August Messer and (2) a book by the Greifswald objectivist Dimitri Michaltschew. Central to Michaltschew's book was the concept of the given. In Part I, I argue that Moore elaborated his concept of sense-data in the wake of the Greifswald concept. Carnap did the same when he wrote his Aufbau, the only difference being that he spoke not of sense-data but of Erlebnisse. This means, I argue, that both Moore's sense-data and Carnap'sErlebnisse have little to do with either British empiricists or the neo-Kantians. In Part II, I try to ascertain what made early analytic philosophy different from all those philosophical groups and movements that either exercised influence on it, or were closely related to it: phenomenologists, Greifswald objectivists, Brentanists. For this purpose, I identify the sine qua non practices of the early analytic philosophers: exactness; acceptance of the propositional turn; descriptivism; objectivism. If one of these practices was not explored by a given philosophical school or group, in all probability, it was not truly analytic

Abstract: Direct Realists believe that perception involves direct awareness of an object not dependent for its existence on the perceiver. Howard Robinson rejects this doctrine in favour of a Sense-Datum theory of perception. His argument against Direct Realism invokes the principle ‘same proximate cause, same immediate effect’. Since there are cases in which direct awareness has the same proximate cerebral cause as awareness of a sense datum, the Direct Realist is, he thinks, obliged to deny this causal principle. I suggest that although Direct Realism is in more than one respect implausible, it does not succumb to Robinson’s argument. The causal principle is true only if ‘proximate cause’ means ‘proximate sufficient cause’, and the Direct Realist need not concede that there is a sufficient cerebral cause for direct awareness of independent objects

Abstract: Questions about perception remain some of the most difficult and insoluble in both epistemology and the philosophy of mind. Perception provides a highly accessible introduction to the area, exploring the philosophical importance of those questions by re-examining the sense-datum theory, once the most popular theory of perception. Howard Robinson surveys the history of arguments for and against the sense-datum theory, from Descartes to Husserl. Robinson contends that the objections to the theory, particularly Wittgenstein's attack on privacy and those of the physicalists, have been unsuccessful. He argues for returning to the theory in order to understand perception. In doing so, he seeks to overturn a consensus that has dominated the philosophy of perception for nearly half a century

Abstract: Nicholas Nathan tries to resist the current version of the causal argument for sense-data in two ways. First he suggests that, on what he considers to be the correct reconstruction of the argument, it equivocates on the sense of proximate cause. Second, he defends a form of disjunctivism, by claiming that there might be an extra mechanism involved in producing veridical hallucination that is not present in perception. I argue that Nathan’s reconstruction of the argument is not the appropriate one, and that, properly interpreted, the argument does not equivocate on proximate cause. Furthermore, I claim that his postulation of a modified mechanism for hallucinations is implausibly ad hoc

Abstract: The notion of representation has become ubiquitous throughout cognitive psychology, cognitive neuroscience and the cognitive sciences generally. This paper addresses the status of mental representations as entities that have been posited to explain cognition. I do so by examining similarities between mental representations and sense-data in both their characteristics and key arguments offered for each. I hope to show that more caution in the adoption and use of representations in explaining cognition is warranted. Moreover, by paying attention to problematic notions of representations, a less problematic sense of representation might emerge

Abstract: (forthcoming in Analysis) We owe the problem of the speckled hen to Gilbert Ryle. It was suggested to A.J. Ayer by Ryle in connection with Ayer’s account of seeing. Suppose that you are standing before a speckled hen with your eyes trained on it. You are in good light and nothing is obstructing your view. You see the hen in a single glance. The hen has 47 speckles on its facing side, let us say, and the hen ap­ pears speckled to you. On Ayer’s view, in seeing the hen, you directly see a speckled sense-datum or appearance. Ryle wondered how many speckles there are on the sense-datum. After all, intu­ itively, the hen does not appear to you to have 47 speckles. And if this is the case, then it does not present to you an appearance with 47 speckles. Equally, however, the hen does not appear to you not to have 47 speckles. So, it does not present an appearance that lacks 47 speckles either

Abstract: This book develops an explanation for the roles of observation and theory in scientific endeavor that occupies the middle ground between empiricism and rationalism, and captures the strengths of both approaches. Brown argues that philosophical theories have the same epistemological status as scientific theories and constructs an epistemological theory that provides an account of the role that theory and instruments play in scientific observation. His theory of perception yields a new analysis of objectivity that combines the traditional view of observation as the foundation of scientific objectivity with the contemporary recognition that observation is theory-dependent

Abstract: My paper has three parts. First I will outline the act/object theory of perceptual experience and its commitments to (a) a relational view of experience and (b) a view of phenomenal character according to which it is constituted by the character of the objects of experience. I present the traditional adverbial response to this, in which experience is not to be understood as a relation to some object, but as a way of sensing. In the second part I argue that acceptance of (a) is independent of acceptance of (b). I then present a modified adverbialism that presents experience as relational in nature but whose character is nevertheless to be explained in terms of the way in which one senses an object. Finally, I will offer an explanation of how a naïve realist about experience can adopt this modified adverbialism and in so doing accommodate the possibility of perceptual error

Abstract: Increasingly prominent in the recent literature on the philosophy of perception, Intentionalism holds that sensory experience is inherently intentional, where to be intentional is to be about, or directed on, something. This article explores Intentionalism's prospects as a viable ontological and epistemological alternative to the traditional trinity of theories of sensory experience: the Sense-Datum Theory, the Adverbial Theory, and the Theory of Appearing

Abstract: Millar argues against the tendency in current philosophical thought to treat sensory experiences as a peculiar species of propositional attitude. While allowing that experiences may in some sense bear propositional content, he presents a view of sensory experiences as a species of psychological state. A key theme in his general approach is that justified belief results from the competent exercise of conceptual capacities, some of which involve an ability to respond appropriately to current experience. In working out this approach the author develops a view of concepts and their mastery, explores the role of groundless beliefs drawing on suggestions of Wittgenstein, illuminates aspects of the thought of Locke, Hume, Quine, and Goldman, and finally offers a response to a sophisticated variety of scepticism

Abstract: This paper develops an adverbial theory of consciousness. Adverbialism is described and endorsed and defended from its near rival, an identity thesis in which conscious mental states are those that the mental subject self-knows immediately that he or she is "in". The paper develops an account of globally supported self-ascription to embed this neo-Brentanian view of experiencing consciously within a more general account of the relation between consciousness and self-knowledge. Following O'Shaughnessy, person level consciousness is explained as a feature of the bundle of mental capacities characteristic of persons: person level consciousness involves a capacity holism. Drawing on Kant, it is argued that if a person is in a mental state intentionally directed to an object then such a subject can "self token" such knowledge. The content of that self-knoweldge supervenes on the possession of a global set of capacities, and this capacity for self-ascription depends on the fact that our experience has a perspectival character with, as it were, nothing at the vanishing point of this perspective. The fact that one can attach the cogito to any one of one's representation shows a truth about the unity of the conscious life of a person that cannot be stated and this capacity is distinguished from self-conscious thinking about oneself. This approach is contrasted to Shoemaker's functionalist treatment of the self-tokening of conscious states and of "self-blindness". It is argued that to be fully consistent, Shoemaker has to abandon the claim that introspectionism is guilty of a self-scanning model or rational control as he seems committed to that model too

Abstract: It is widely agreed that perceptual experience is a form of intentionality, i.e., that it has representational content. Many philosophers take this to mean that like belief, experience has propositional content, that it can be true or false. I accept that perceptual experience has intentionality; but I dispute the claim that it has propositional content. This claim does not follow from the fact that experience is intentional, nor does it follow from the fact that experiences are accurate or inaccurate. I end by considering the relationship between this question and the question of whether experience has non-conceptual content

Abstract: Representationalists currently cannot explain counter-examples that involve _indeterminate _perceptual content, but a _double content_ (DC) view is more promising. Four related cases of perceptual imprecision are used to outline the DC view, which also applies to imprecise photographic content. Next, inadequacies in the more standard single content (SC) view are demonstrated. The results are then generalized so as to apply to the content of any kinds of non-conventional representation. The paper continues with evidence that a DC account provides a moderate rather than extreme realist account of perception, and it concludes with an initial analysis of the failure of nomic covariance accounts of information in indeterminacy cases

Abstract: 1. Introduction When it comes to perception, representationalism is all the rage. Representationalism is a claim about the phenomenal character of perceptual experiences: According to representationalism, phenomenal character is fully determined by the representational content of perceptual experiences (cf. Tye 2002, 45). In other words, phenomenal character, what it is like, for instance, to have an experience as of something red, is either supervenient upon or identical with that experience

Abstract: This somewhat odd paper argues against a representational view of visual experience using an intricate "inversion" type thought experiment involving double vision: two subjects could represent external space in the same way while differing phenomenally due to different "spread" in their double images. The spatial structure of the visual field is explained not by representation of external space but functionally, in terms of the possible locations of an attentional spotlight. I'm fond of the ideas in this paper but doubt I'll be returning to it soon.

Abstract: Conceptualism is the thesis that, for any perceptual experience E, (i) E has a Fregean proposition as its content and (ii) a subject of E must possess a concept for each item represented by E. We advance a framework within which conceptualism may be defended against its most serious objections (e.g., Richard Heck's argument from nonveridical experience). The framework is of independent interest for the philosophy of mind and epistemology given its implications for debates regarding transparency, relationalism and representationalism, demonstrative thought, phenomenal character, and the speckled hen objection to modest foundationalism.

Abstract: Recently, many have argued that phenomenal content supervenes on representational content; i.e. that the phenomenal character of an experience is wholly determined (metaphysically, not causally) by the representational content of that experience. This paper it identifies many counter-examples to intentionalism. Further, this paper shows that, if intentionalism were correct, that would require that an untenable form of representational atomism also be correct. Our argument works both against the idea that phenomenal content supervenes on “conceptual” content and also against the idea that it supervenes on “non-conceptual” content. It is also shown that the distinction between conceptual and non-conceptual content has been wrongly conceived as distinction between different kinds of information: in fact, it is a distinction between ways of packaging information that is, in itself, neither conceptual or non-conceptual

Abstract: Seeing, Doing, and Knowing is an original and comprehensive philosophical treatment of sense perception as it is currently investigated by cognitive neuroscientists. Its central theme is the task-oriented specialization of sensory systems across the biological domain; these systems coevolve with an organism's learning and action systems, providing the latter with classifications of external objects in terms of sensory categories purpose--built for their need. On the basis of this central idea, Matthen presents novel theories of perceptual similarity, content, and realism. His work will be a stimulating resource for a wide range of scholars and students across philosophy and psychology

Abstract: H. H. Price (1932) held that experience is essentially presentational. According to Price, when one has an experience of a tomato, nothing can be more certain than that there is something of which one is aware. Price claimed that the same applies to hallucination. In general, whenever one has a visual experience, there is something of which one is aware, according to Price. Call this thesis Item-Awareness

Abstract: Strong or Pure Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its Intentional content. Strong or Pure Anti -Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its non-Intentional properties

Abstract: Throughout his discussion, Clark speaks constantly of phenomenal and qualitative properties. But properties, like any other posited entities, ought to earn their explanatory keep, and this I don't think Clark's phenomenal or qualitative properties actually do. I argue that all the work he enlists for them could be done better by purely intentional contents of our sentient states; that is, they could better be regarded as mere intentional properties, not real ones. Clark eschews such intentionalism, but I see no reason for him to resist a properly deflated version of it that I sketch. Moreover, such intentionalism seems to me to stand a better chance than Clark's reliance on properties in explaining the peculiar ways in which experience appears to us that so concern the qualiaphile

Abstract: This paper considers the claim that perceptual experience is “transparent”, in the sense that nothing other than the apparent public objects of perception are available to introspection by the subject of such experience. I revive and strengthen the objection that blurred vision constitutes an insuperable objection to the claim, and counter recent responses to the general objection. Finally the bearing of this issue on representationalist accounts of the mind is considered

Abstract: I argue that the transparency of experience provides the basis of arguments both for intentionalism -- understood as the view that there is a necessary connection between perceptual content and perceptual phenomenology -- and for the view that the contents of perceptual experiences are Russellian propositions. While each of these views is popular, there are apparent tensions between them, and some have thought that their combination is unstable. In the second half of the paper, I respond to these worries by arguing that Russellianism is consistent with intentionalism, that their conjunction is consistent with both internalism about phenomenology and externalism about perceptual content, and that the resulting view receives independent support from the relationship between hallucination and thought.

Abstract: There is a view abroad on which (a) perceptual experience has (a) representational content in this sense: in it something is represented to the perceiver as so. On the view, a perceptual experience has a face value at which it may be taken, or which may be rejected. This paper argues that that view is mistaken: there is nothing in perceptual experience which makes it so that in it anything is represented as so (except insofar as the perceiver represents things to himself as so). In that sense, the senses are silent, or, in Austin's term, dumb. Perceptual experience is not as such either veridical or delusive. It may mislead, but it does not take representation to accomplish that

Abstract: Disjunctivists (Hinton 1973, Snowdon 1990, Martin 2002, 2006) often motivate their approach to perceptual experience by appealing in part to the claim that in cases of veridical perception, the subject is directly in contact with the perceived object. When I perceive a table, for example, there is no table-like sense-impression that stands as an intermediary between the table and me. Nor am I related to the table as I am to a deer when I see its footprint in the snow. I do not experience the table by experiencing some- thing else over and above the table and its facing surface. I see the facing surface of the table directly

Abstract: Today, many philosophers think that perceptual experiences are conscious mental states with representational content and phenomenal character. Subscribers to this view often go on to construe experience more precisely as a propositional attitude sui generis ascribing sensible properties to ordinary material objects. I argue that experience is better construed as a kind of belief ascribing 'phenomenal' properties to such objects. A belief theory of this kind deals as well with the traditional arguments against doxastic accounts as the sui generis view. Moreover, in contrast to sui generis views, it can quite easily account for the rational or reason providing role of experience

Abstract: Any adequate account of perceptual experience has to provide answers to the following questions: What kind, and form of, content do experiences have? What kind of mental states are they? Many, if not most philosophers of perception today agree that experiences have representational contents of the form x is F, where x ranges over material objects and F over sensible properties. I argue that such a "naive semantics" for experiences has to give the wrong answer to the second question. Because of their justificatory role for, and inferential integration into, a subject's belief system, experiences themselves have to be construed as a kind of belief. I also sketch a semantics that allows experiences to be beliefs.

Abstract: Both traditional and naturalistic epistemologists have long assumed that the examination of human psychology has no relevance to the goal of traditional epistemology, that of providing first-person guidance in determining the truth. Without slipping into naturalism, I apply insight about the psychology of human perception and concept-formation to a very traditional epistemological project: the foundationalist approach to the epistemic regress problem. I argue that direct realism about perception can help solve the regress problem and support a foundationalist account of justification, but only if it is supplemented by an abstractionist theory of concept-formation, the view that it is possible to abstract concepts directly from the empirically given. Critics of direct realist solutions like Laurence BonJour are correct that an account of direct perception by itself does not provide an adequate account of justification. However a direct realist account of perception can inform the needed theory of concept-formation, and leading critics of abstractionism like McDowell and Sellars, direct realists about perception themselves, fail to appreciate the ways in which their own views about perception help fill gaps in earlier accounts of abstractionism. Recognizing this undercuts both their objections to abstractionism and (therefore) their objections to foundationalism, as well.

Abstract: 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

Abstract: My paper has three parts. First I will outline the act/object theory of perceptual experience and its commitments to (a) a relational view of experience and (b) a view of phenomenal character according to which it is constituted by the character of the objects of experience. I present the traditional adverbial response to this, in which experience is not to be understood as a relation to some object, but as a way of sensing. In the second part I argue that acceptance of (a) is independent of acceptance of (b). I then present a modified adverbialism that presents experience as relational in nature but whose character is nevertheless to be explained in terms of the way in which one senses an object. Finally, I will offer an explanation of how a naïve realist about experience can adopt this modified adverbialism and in so doing accommodate the possibility of perceptual error

Abstract: Michael Martin aims to affirm a certain pattern of first-person thinking by advocating disjunctivism, a theory of perceptual experience which combines naive realism with the epistemic conception of hallucination. In this paper I argue that we can affirm the pattern of thinking in question without the epistemic conception of hallucination. The first part of my paper explains the link that Martin draws between the first-person thinking and the epistemic conception of hallucination. The second part of my paper explains how we can achieve Martin’s ambition without Martin’s theory. One resource that I enlist for this purpose is a naive-realist friendly conception of first-person access to experience. The metaphysical theory that I enlist is a form of naive realism that endorses an intentionalist or representationalist “common-factor” approach to veridical and hallucinatory experience. The third part of my paper briefly develops this theory

Abstract: The naive realist takes a veridical visual experience to be an immediate relation to external entities. Is this how such an experience is phenomenally, by its phenomenal character? Only if there can be phenomenal error, since a hallucinatory experience phenomenally matching such a veridical experience would then be phenomenally but not in fact such a relation. Fortunately, such phenomenal error can be avoided: the phenomenal character of a visual experience involves immediate awareness of a sort of picture of external entities, as on a representative theory of perception. The attraction of naive realism results from an erroneous projection of the immediacy of the subject's awareness of this picture onto the external entities pictured.

Abstract: This paper expands on the discussion in the first section of 'Beyond phenomenal naivete'. Let Phenomenal Naivete be understood as the doctrine that some phenomenal characters of veridical experiences are factive properties concerning the external world. Here I present in detail a phenomenological case for Phenomenal Naivete and an argument from hallucination against it. I believe that these arguments show the concept of phenomenal character to be defective, overdetermined by its metaphysical and epistemological commitments together with the world. This does not establish a gappish eliminativism, but a gluttish pluralism, on which there are many imperfect deservers of the name 'phenomenal character'. Different projects in the philosophy of mind -- phenomenology, philosophy of conscious, metaphysics and epistemology of perception -- are concerned with different deservers of the name.

Abstract: Direct realists think that we can't get a clear view the nature of /hallucinating a white picket fence/: is it /representing a white picket fence/? is it /sensing white-picket-fencily/? is it /being acquainted with a white' picketed' sense-datum/? These are all epistemic possibilities for a single experience; hence they are all metaphysical possibilities for various experiences. Hallucination itself is a disjunctive or "multidisjunctive" category. I rebut MGF Martin's argument from statistical explanation for his "epistemic" conception of hallucination, but his view embeds in my view as a "reference-fixer".

Abstract: My aim is to arrive at a better understanding of the distinction between direct realism and representationalism by offering a critical analysis of Steven Nadler

Abstract: A concern for realism motivates a fundamental strand of Oxford reflection on perception. Begin with the realist conception of knowledge. The question then will be: What must perception be like if we can know something about an object without the mind by seeing it? What must perception be if it can, on occasion, afford us with proof concerning a subject matter independent of the mind? The resulting conception of perception is not unlike the conception of perception shared by Cambridge realists such as Moore and Russell. Roughly speaking, perception is conceived to be a fundamental and irreducible sensory mode of awareness of mind-independent objects, a non-propositional mode of awareness that enables those with the appropriate recognitional capacities to have propositional knowledge concerning that subject matter. The difference between Oxford and Cambridge realism concerns the extent of this fundamental sensory mode of awareness. Whereas Oxford realists maintained that perception affords us this non-propositional mode of awareness, Cambridge realists maintained that this distinctive mode of awareness has a broader domain. Let experience be the genus of which perception is a species. Cambridge realists maintained that a experience, and not just perception, involves this non-propositional sensory mode of awareness. Cambridge realists are thus committed to a kind of experien- tial monism—the thesis that experience has a unitary nature. Specifically, all experience, perceptual and non-perceptual alike, involves, as part of its nature, a non-propositional sensory mode of awareness. Even subject to illusion or hallucination, there is something of which one is aware. And with that, they were an application of the argument from illusion, or hallucination, or conflicting appearances away from immaterial sense data and a representative realism that tended, over time, to devolve into a form of..

Abstract: Recently representationalists have cited a phenomenon known as the transparency of experience in arguments against the qualia theory. Representationalists take transparency to support their theory and to work against the qualia theory. In this paper I argue that representationalist assessment of the philosophical importance of transparency is incorrect. The true beneficiary of transparency is another theory, naïve realism. Transparency militates against qualia and the representationalist theory of experience. I describe the transparency phenomenon, and I use my description to argue for naïve realism and against representationalism and the qualia theory. I also examine the relationship between phenomenological study and phenomenal character, and discuss the results in connection with the argument from hallucination

Abstract: I describe a naive realist conception of perceptual knowledge, which faces a challenge from the idea that normal perceivers and brains-in-vats have equally justified perceptual beliefs. I defend the naive realist position from Nicholas Silins's recent version of this challenge. I argue that Silins's main objection fails, and that the naive realist understanding of perceptual knowledge can be reconciled with the idea that brains-in-vats have justified perceptual beliefs

Abstract: Working from a naïve-realist perspective, I examine first-person knowledge of one’s perceptual experience. I outline a naive-realist theory of how subjects acquire knowledge of the nature of their experiences, and I argue that naive realism is compatible with moderate, substantial forms of first-person privileged access. A more general moral of my paper is that treating “success” states like seeing as genuine mental states does not break up the dynamics that many philosophers expect from the phenomenon of knowledge of the mind.

Abstract: I defend a view of the structure of visual property-awareness by considering the phenomenon of perceptual constancy. I argue that visual property-awareness is a three-place relation between a subject, a property, and a manner of presentation. Manners of presentation mediate our visual awareness of properties without being objects of visual awareness themselves. I provide criteria of identity for manners of presentation, and I argue that our ignorance of their intrinsic nature does not compromise the viability of a theory that employs them. In closing, I argue that the proposed manners of presentation are consistent with key direct-realist claims about the structure of visual awareness.

Abstract: Plausibly, any adequate theory of perception must (a) solve what Alva Noë calls 'the problem of perceptual presence,' and (b) do justice to the direct realist idea that what is given in perception are garden-variety spatiotemporal particulars. This paper shows that, while Noë's sensorimotor view arguably satisfies the first of these conditions, it does not satisfy the second. Moreover, Noë is wrong to think that a naïve realist approach to perception cannot handle the problem of perceptual presence. Section three of this paper develops a version of naïve realism that meets both of the adequacy conditions above. This paper thus provides strong considerations in favor of naïve realism

Abstract: Since the demise of the Sense-Datum independent objects or events to be objects Theory and Phenomenalism in the last cenof perception; however, unlike Direct Retury, Direct Realism in the philosophy of alists, Indirect Realists take this percepperception has enjoyed a resurgence of tion to be indirect by involving a prior popularity.1 Curiously, however, although awareness of some tertium quid between there have been attempts in the literature the mind and external objects or events.3 to refute some of the arguments against Idealists and Phenomenalists agree with Direct Realism, there has been, as of yet, the Indirect Realists

Abstract: In this paper, I attempt to demonstrate the structure of Sellars' critical direct realism in the philosophy of perception. This position is original because it attempts to balance two claims that many have thought to be incompatible: (1) that perceptual knowledge is direct, i.e., not inferential, and (2) that perceptual knowledge is irreducibly conceptual. Even though perceptual episodes are not the result of inferences, they must still stand within the space of reasons if they are to be counted not only as knowledge, but also as thoughts directed at the world. The goal of this paper is to demonstrate how Sellars elaborates and defends this position

Abstract: Inspired by the writings of J. M. Hinton (1967a, 1967b, 1973), but ushered into the mainstream by Paul Snowdon (1980–1, 1990–1), John McDowell (1982, 1986), and M. G. F. Martin (2002, 2004, 2006), disjunctivism is currently discussed, advocated, and opposed in the philosophy of perception, the theory of knowledge, the theory of practical reason, and the philosophy of action. But what is disjunctivism?

Abstract: McDowell has argued that external world scepticism is a pressing problem only in so far as we accept, on the basis of the argument from illusion, the claim that perceiving that p and hallucinating that p involve a highest common factor

Abstract: In his Dewey Lectures,1 Hilary Putnam argues that contemporary philosophy cannot solve nor see its way past the traditional problem of how language or thought hooks on to

Abstract: Strong or Pure Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its Intentional content. Strong or Pure Anti -Intentionalism is the claim that the phenomenal character of any perceptual experience can be exhaustively characterized solely by reference to its non-Intentional properties

Abstract: Paul Pietroski, McGill University The general topic of_ Mind and World_, the written version of John McDowell's 1991 John Locke Lectures, is how `concepts mediate the relation between minds and the world'. And one of the main aims is `to suggest that Kant should still have a central place in our discussion of the way thought bears on reality' (1).1 In particular, McDowell urges us to adopt a thesis that he finds in Kant, or perhaps in Strawson's Kant: the content of experience is conceptualized; _what_ we experience is always the kind of thing that we could also believe. When an agent has a veridical experience, she `takes in, for instance sees, _that things are thus and so_' (9). McDowell's argument for this thesis is indirect, but potentially powerful. He discusses a tension concerning the roles of experience and conceptual capacities in thought, and he claims that the only adequate resolution involves granting that experiences have conceptualized content. The tension, elaborated below, can be expressed roughly as follows: judgments must be somehow constrained by features of the external environment, else judgments would be utterly divorced from the world they purport to be about; yet our judgments must be somehow free of external control, else we could give no sense to the idea that we are responsible for our judgments

Abstract: There are currently two main philosophical theories of perception - Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter forms the groundwork for most scientific theories in this area. The paper describes a recent experiment involving retinal and cortical rivalry that provides strong empirical evidence that the Direct Realist theory is incorrect. There are of course a large number of related experiments on visual perception that would tend to lead us to the same conclusion, but the experiment described in this paper does so in a singularly direct and straightforward manner. Often the most telling experiments are the simplest

Abstract: In the present paper, I shall argue that disjunctively construed naïve realism about the nature of perceptual experiences succumbs to the empirically inspired causal argument. The causal argument highlights as a first step that local action necessitates the presence of a type-identical common kind of mental state shared by all perceptual experiences. In a second step, it sets out that the property of being a veridical perception cannot be a mental property. It results that the mental nature of perceptions must be exhausted by the occurrence of inner sensory experiences that narrowly supervene on the perceiver. That is, empirical objects fail directly to determine the perceptual consciousness of the perceiver. The upshot is that not only naïve realism, but also certain further forms of direct realism have to be abandoned.

Abstract: In this paper, I will ask whether naïve realists have the conceptual resources for meeting the challenge stemming from the causal argument. As I interpret it, naïve realism is committed to disjunctivism. Therefore, I first set out in detail how one has to formulate the causal argument against the background of disjunctivism. This discussion is above all supposed to work out the key assumptions at stake in the causal argument. I will then go on to sketch out several possible rejoinders on behalf of naïve realism. It will be shown that they all fail to provide a satisfying account of how causation and perceptual consciousness fit together. Accordingly, the upshot will be that the causal argument provides good reason to abandon disjunctivism and, instead, to promote a common factor view of perception.

Abstract: In this paper I argue for a theory of perception distinct both from classical sense-datum theories and from intentionalist theories, that is theories according to which one perceives external objects by dint of a relation with a propositional content. The alternative I propose completely rejects any representational element in perception. When one sees that an object has a property, the situation or state of affairs of its having that property is one's perception, so that the object and property are literally part of one's mind. The most obvious objection to this view is that it embodies a rampant form of idealism. It is argued to the contrary, via consideration of the metaphysics of situations, that the theory is entirely consistent with a robustly realist view of the world

Abstract: Ordinary people tend to be realists regarding perceptual experience, that is, they take perceiving the environment as a direct, unmediated, straightforward access to a mindindependent reality. Not so for (ordinary) philosophers. The empiricist influence on the philosophy of perception, in analytic philosophy at least, made the problem of perception synonymous with the view that realism is untenable. Admitting the problem (and trying to offer a view on it) is tantamount to rejecting ordinary people’s implicit realist assumptions as naive. So what exactly is the problem? We can approach it via one of the central arguments against realism – the argument from hallucination. The argument is intended as a proof that in ordinary, veridical cases of perception, perceivers do not have an unmediated perceptual access to the world. There are many versions of it; I propose the following1: 1. Hallucinations that are subjectively indistinguishable from veridical perceptions are possible. 2. If two subjective states are indistinguishable, then they have a common nature. 3. The contents of hallucinations are mental images, not concrete external objects. 4. Therefore, the contents of veridical perceptions are mental images rather than concrete external objects. The key move is, I believe, from the fact that hallucinations that are subjectively indistinguishable from cases of veridical perception are possible to an alleged common element, factor, or nature, in the form of a mental state, in the two cases – that is, premise 2. Disjunctivism, at its core, can be taken as simply denying this move, and arguing that all that follows from the premise stating the possibility of hallucinations that are subjectively indistinguishable from cases veridical perception is that there is a broader category, that of “experience as of...”, which encompasses both cases..

Abstract: A theory is disjunctive insofar as it distinguishes genuine from non-genuine cases of some phenomenon P on the grounds that no salient feature of cases of one type is common to cases of the other type. Genuine and non-genuine cases of P are, in this sense, fundamentally different. Those who advocate disjunctivist theories have (for the most part) been concerned with perception and perceptual knowledge. This entry outlines two such theories: the disjunctivist theory of experience (cf. Brewer, Hinton, Martin, Snowdon, Travis) and the disjunctivist theory of appearances (McDowell)

Abstract: The question how to account for illusion has had a prominent role in shaping theories of perception throughout the history of philosophy. Prevailing philosophical wisdom today has it that phenomena of illusion force us to choose between the following two options. First, reject altogether the early modern empiricist idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience. Instead we must characterize perceptual experience entirely in terms of its representational content. Second, retain the early modern idea that the core subjective character of experience is simply constituted by the identity of its direct objects, but admit that these must be mind-dependent entities, distinct from the mind-independent physical objects we all know and love. I argue here that the early modern empiricists had an indispensable insight. The idea that the core subjective character of perceptual experience is to be given simply by citing the object presented in that experience is more fundamental than any appeal to perceptual content, and can account for illusion, and indeed hallucination, without resorting to the problematic postulation of any such mind-dependent objects.

Abstract: Naive realism is one of the oldest theories of perception. To a first approximation, naive realism is the view that perception is a direct relation between a subject and an object. Many historical philosophers (from Locke to Russell) argued that naive realism must be rejected on the grounds that hallucinations are perceptual experiences without an object. Contemporary philosophers have resurrected the theory by insisting that genuine cases of perception have a different structure or a different metaphysical status than non-genuine ones. This version of naive realism has come to be known as ‘disjunctivism’. Epistemological disjunctivism and disjunctivism about phenomenal belief, or what I shall call ‘Epistemological disjunctivism’, have also gained popularity in recent years. More recently disjunctivist accounts of bodily movements, abilities and reasons for action have entered the philosophical scene. This entry focuses on the contemporary debate about disjunctivism: its characterization, its motivation and its potential shortcomings

Abstract: I argue that McDowell-style disjunctivism, as the position is often cashed out, goes wrong because it takes the good epistemic standing of veridical perception to be grounded in “manifest” facts which do not necessarily satisfy any epistemic constraints. A better form of disjunctivism explains the difference between good and bad cases in terms of epistemic constraints that the states satisfy. This view allows us to preserve McDowell’s thesis that good cases make facts manifest, as long as manifest facts must satisfy epistemic constraints

Abstract: This essay is a long one. It is not meant to be read in a single sitting. Its structure is as follows. In section I, I explicate perceptual anti-individualism. Section II centers on the two aspects of the representational content of perceptual states. Sections III and IV concern the nature of the empirical psychology of vision, and its bearing on the individuation of perceptual states. Section V shows how what is known from empirical psychology undermines disjunctivism and hence certain further views that entail it, including naive realism. In Section VI, I raise a further point against disjunctivism. Section VII indicates how general reflection on perceptual perspective and epistemic ability supports the constraints from empirical psychology. It also explains how reflection on veridicality conditions, psychological explanation, and cognitive ability conspire to force recognition of the two kinds of representation mentioned in the preceding paragraph. In the Appendix, I criticize attempts to support disjunctivism.

Abstract: This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological.

Abstract: Philosophers of mind have long been interested in the relation between two ideas: that causality plays an essential role in our understanding of the mental; and that we can gain an understanding of belief and desire by considering the ascription of attitudes to people on the basis of what they say and do. Many have thought that those ideas are incompatible. William Child argues that there is in fact no tension between them, and that we should accept both. He shows how we can have a causal understanding of the mental without having to see attitudes and experiences as internal, causally interacting entities and he defends this view against influential objections. The book offers detailed discussions of many of Donald Davidson's contributions to the philosophy of mind, and also considers the work of Dennett, Anscombe, McDowell, and Rorty, among others. Issues discussed include: the nature of intentional phenomena; causal explanation; the character of visual experience; psychological explanation; and the causal relevance of mental properties

Abstract: I argue that one reason for being a disjunctivist advanced by McDowell (having to do with the indefeasibility of perceptual knowledge) fails because it ignores the distinction between justification and warrant.

Abstract: It is argued that Husserl was an “externalist” in at least one sense. For it is argued that Husserl held that genuinely perceptual experiences—that is to say, experiences that are of some real object in the world—differ intrinsically, essentially and as a kind from any hallucinatory experiences. There is, therefore, no neutral “content” that such perceptual experiences share with hallucinations, differing from them only over whether some additional non-psychological condition holds or not. In short, it is argued that Husserl was a “disjunctivist”. In addition, it is argued that Husserl held that the individual object of any experience, perceptual or hallucinatory, is essential to and partly constitutive of that experience. The argument focuses on three aspects of Husserl’s thought: his account of intentional objects, his notion of horizon, and his account of reality

Abstract: One central fact about hallucinations is that they may be subjectively indistinguishable from perceptions. Indeed, it has been argued by M. G. F. Martin and others that the hallucinatory experiences concerned cannot — and need not — be characterised in any more positive general terms. This epistemic conception of hallucinations has been advocated as the best choice for proponents of experiential (or ‘na¨ıve realist’) disjunctivism — the view that perceptions and hallucinations differ essentially in their introspectible subjective characters. In this chapater, I aim to formulate and defend an intentional alternative to experiential disjunctivism called experiential intentionalism. This view does not only enjoy some advantages over its rival, but also can hold on to the epistemic conception of perception-like hallucinations. First of all, I try to spell out in a bit more detail in which sense hallucinations may be subjectively indistinguishable from perceptions, and why this leads us to erroneously judge them to be perceptions (cf. sections I–III and VIII). Then, I raise three challenges each for experiential disjunctivism and its orthodox intentionalist counterparts (cf. sections IV and V), notably in respect of the need to explicate why a perception-like hallucination still makes the same judgements reasonable from the subject’s perspective as the corresponding perceptions. And, finally, I propose my alternative both to experiential disjunctivism and to orthodox intentionalism. Experiential intentionalism takes perceptions and perception-like hallucinations to share a common character partly to be spelled out in intentional — and, hence, normative — terms (cf. sections VI and VII). The central thought is that the hallucinations concerned are intentionally — and erroneously — presented to us as perceptual relations to the world. I aim to show that the resulting view can meet all six challenges (cf. sections VI–VIII). I end..

Abstract: One of the most powerful arguments against intentionalism and in favour of disjunctivism about perceptual experiences has been formulated by M. G. F. Martin in his paper The Transparency of Experience. The overall structure of this argument may be stated in the form of a triad of claims which are jointly inconsistent

Abstract: In the eyes of some of its critics, disjunctivism fails to support adequately the key claim that a particular hallucination might be indistinguishable from a certain kind of veridical perception despite the two states having nothing other than this in common. Scott Sturgeon, for example, has complained that disjunctivism ‘‘offers no positive story about hallucination at all’’ (2000: 11) and therefore ‘‘simply takes [indistinguishability] for granted’’ (2000: 12). So according to Sturgeon, what the disjunctivist needs to provide is a plausible explanation of just how two mental states which have no common component might be indistinguishable for their subject and this in turn will require the telling of a positive story about hallucination. This is the goal of the present essay

Abstract: In this paper, I present a version of a sense-data approach to perception, which differs to a certain extent from well-known versions like the one put forward by Jackson. I compare the sense-data view to the currently most popular alternative theories of perception, the so-called Theory of Appearing (a very specific form of disjunctivist approaches) on the one hand and reductive representationalist approaches on the other. I defend the sense-data approach on the basis that it improves substantially on those alternative theories

Abstract: John McDowell’s original motivation of disjunctivism occurs in the context of a problem regarding other minds. Recent commentators have insisted that McDowell’s disjunctivism should be classed as an epistemological disjunctivism about epistemic warrant, and distinguished from the perceptual disjunctivism of Hinton, Snowdon and others. In this paper I investigate the relation between the problem of other minds and disjunctivism, and raise some questions for this interpretation of McDowell.

Abstract: We know things that entail things we apparently cannot come to know. This is a problem for those of us who trust that knowledge is closed under entailment. In the paper I discuss the solutions to this problem offered by epistemic disjunctivism and contextualism. The contention is that neither of these theories has the resources to deal satisfactory with the problem

Abstract: Let's be externalists about perceptual consciousness and think the form of veridical perceptual consciousness includes /seeing this or that mind-independent particular and its colors/. Let's also take internalism seriously, granting that spectral inversion and hallucination can be "phenomenally" the same as normal seeing. Then perceptual consciousness and phenomenality are different, and so we need to say how they are related. It's complicated!

Phenomenal sameness is (against all odds) /reflective indiscriminability/. I build a "displaced perception" account of reflection on which indiscriminability stems from shared "qualia". Qualia are compatible with direct realism: while they generate an explanatory gap (and colors do not), so does /seeing/; qualia are excluded from perceptual consciousness by its "transparency"; instead, qualia are aspects of thought about the perceived environment.

The asymmetry between my treatments of color and seeing is grounded in the asymmetry between ignorance and error: while inversion shows that normal subjects are ignorant of the natures of the colors, hallucination shows not that perceivers are ignorant of the nature of seeing but that hallucinators are prone to error about their condition. Past literature has treated inversion and hallucination as on a par: externalists see error in both cases, while internalists see mutual ignorance. My account is so complicated because plausible results require mixing it up.

Abstract: Direct realists think that we can't get a clear view the nature of /hallucinating a white picket fence/: is it /representing a white picket fence/? is it /sensing white-picket-fencily/? is it /being acquainted with a white' picketed' sense-datum/? These are all epistemic possibilities for a single experience; hence they are all metaphysical possibilities for various experiences. Hallucination itself is a disjunctive or "multidisjunctive" category. I rebut MGF Martin's argument from statistical explanation for his "epistemic" conception of hallucination, but his view embeds in my view as a "reference-fixer".

Abstract: Inspired by the writings of J. M. Hinton (1967a, 1967b, 1973), but ushered into the mainstream by Paul Snowdon (1980–1, 1990–1), John McDowell (1982, 1986), and M. G. F. Martin (2002, 2004, 2006), disjunctivism is currently discussed, advocated, and opposed in the philosophy of perception, the theory of knowledge, the theory of practical reason, and the philosophy of action. But what is disjunctivism?

Abstract: Right now, I see a computer in front of me. Now, according to current philosophical orthodoxy, I could have the very same perceptual experience that I’m having right now even if I were not seeing a computer in front of me. Indeed, such orthodoxy tells us, I could have the very same experience that I’m having right now even if I were not seeing anything at all in front of me, but simply suffering from a hallucination. More generally, someone can have the very same perceptual experience no matter whether she is enjoying a veridical perception of some mindindependent object, or merely hallucinating. What differs across these two kinds of case is not the kind of experience that she has, but rather the connections between her experience and the rest of the world. So say most philosophers

Abstract: Much of the recent debate regarding scepticism has focussed on a certain template sceptical argument and a rather restricted set of proposals concerning how one might deal with that argument. Throughout this debate the ‘Moorean’ response to scepticism is often cited as a paradigm example of how one should not respond to the sceptical argument, so conceived. As I argue in this paper, however, there are ways of resurrecting the Moorean response to the sceptic. In particular, I consider the prospects for three such proposals in this regard: a classical epistemic internalist neo-Mooreanism, a classical epistemic externalist neo-Mooreanism, and a non-classical McDowellian epistemic internalist neo-Mooreanism, and maintain that the last two of these proposals (both of which make appeal to a disjunctivist account of perception, broadly conceived) merit further exploration. Indeed, I claim that a suitably qualified version of neo-Mooreanism would actually sit quite well with the general philosophical motivations behind other key anti-sceptical views and I argue that given this fact neo-Mooreanism is actually at a dialectical advantage relative to other views when it comes to dealing with the sceptical problem as it is typically conceived.

Abstract: Nicholas Nathan tries to resist the current version of the causal argument for sense-data in two ways. First he suggests that, on what he considers to be the correct reconstruction of the argument, it equivocates on the sense of proximate cause. Second, he defends a form of disjunctivism, by claiming that there might be an extra mechanism involved in producing veridical hallucination that is not present in perception. I argue that Nathan’s reconstruction of the argument is not the appropriate one, and that, properly interpreted, the argument does not equivocate on proximate cause. Furthermore, I claim that his postulation of a modified mechanism for hallucinations is implausibly ad hoc

Abstract: Early formulations of disjunctivism about perception refused to give any positive account of the nature of hallucination, beyond the uncontroversial fact that they can in some sense seem to the same to the subject as veridical perceptions. Recently, some disjunctivists have attempt to account for hallucination in purely epistemic terms, by developing detailed account of what it is for a hallucinaton to be indiscriminable from a veridical perception. In this paper I argue that the prospects for purely epistemic treatments of hallucinations are dim, and that this undermines the case for disjunctivism

Abstract: In the present paper, I shall argue that disjunctively construed naïve realism about the nature of perceptual experiences succumbs to the empirically inspired causal argument. The causal argument highlights as a first step that local action necessitates the presence of a type-identical common kind of mental state shared by all perceptual experiences. In a second step, it sets out that the property of being a veridical perception cannot be a mental property. It results that the mental nature of perceptions must be exhausted by the occurrence of inner sensory experiences that narrowly supervene on the perceiver. That is, empirical objects fail directly to determine the perceptual consciousness of the perceiver. The upshot is that not only naïve realism, but also certain further forms of direct realism have to be abandoned.

Abstract: Recent scientific work aiming to give a neurobiological explanation of phenomenal consciousness has largely focused on finding neural correlates of consciousness (NCC). The hope is that by locating neural correlates of phenomenally conscious mental states, some light will be cast on how the brain is able to give rise to such states. In this paper I argue that NCC research is unable to produce evidence of such neural correlates. I do this by considering two alternative interpretations of NCC research—an eliminativist and a disjunctivist interpretation. I show that each of these interpretations is compatible with the scientific data and yet is more parsimonious than accounts involving the supposed phenomenon of phenomenal consciousness

Abstract: In this paper, I examine the so-called disjunctive views on hallucinations. I argue that neither of the options open to the disjunctivist is capable of accommodating basic phenomenological facts about hallucinatory experiences and the explanatory demands behind the classical argument from hallucination. A positive characterization of the hallucinatory case is not attractive to a disjunctivist once she is disposed to accept certain commonalities with veridical experiences. Negative disjunctivism glosses the hallucinatory disjunct in terms of indiscriminability. I will argue that this move either renounces to characterize phenomenally the hallucinatory experience or does not take seriously questions about why indiscriminability is possible in the phenomenal realm

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

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

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

Abstract: As our chief aim is a comprehensive theory of perception which will cover all the facts, ... JR Smythies' Analysis of Perception I discuss in Ch. VI, § 6. ...

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

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

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

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

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

Abstract: Plausibly, any adequate theory of perception must (a) solve what Alva Noë calls 'the problem of perceptual presence,' and (b) do justice to the direct realist idea that what is given in perception are garden-variety spatiotemporal particulars. This paper shows that, while Noë's sensorimotor view arguably satisfies the first of these conditions, it does not satisfy the second. Moreover, Noë is wrong to think that a naïve realist approach to perception cannot handle the problem of perceptual presence. Section three of this paper develops a version of naïve realism that meets both of the adequacy conditions above. This paper thus provides strong considerations in favor of naïve realism

Abstract: In a recent article, Roy Sorensen proposed a very interesting puzzle involving shadows – The Disappearing Act puzzle (2006). It was left unsolved there. Nevertheless, in his latest book he has added a new thought in guise of a solution to it (2008: 73-75). In what follows I will argue that Sorensen’s solution has some shortcomings, and will offer an alternative to it

Abstract: Philosophers of mind have long been interested in the relation between two ideas: that causality plays an essential role in our understanding of the mental; and that we can gain an understanding of belief and desire by considering the ascription of attitudes to people on the basis of what they say and do. Many have thought that those ideas are incompatible. William Child argues that there is in fact no tension between them, and that we should accept both. He shows how we can have a causal understanding of the mental without having to see attitudes and experiences as internal, causally interacting entities and he defends this view against influential objections. The book offers detailed discussions of many of Donald Davidson's contributions to the philosophy of mind, and also considers the work of Dennett, Anscombe, McDowell, and Rorty, among others. Issues discussed include: the nature of intentional phenomena; causal explanation; the character of visual experience; psychological explanation; and the causal relevance of mental properties

Abstract: The subjective character of a given experience leaves open the question of its precise status. If it looks to a subject K as if there is an object of a kind F in front of him, the experience he is having could be veridical, or hallucinatory. Advocates of the Causal Theory of perception (whom I shall call

Abstract: Much recent discussion about the nature of perception has focused on the dispute between the Causal Theory of Perception and the rival Disjunctive View. There are different versions of the Causal Theory (the abbreviation I shall use), but the point upon which they agree is that perception involves a conscious experience which is logically distinct from the particular physical object perceived. 1 On the opposed Disjunctive View, the perceptual experience is held to be inseparable from the object perceived; what is directly present to conscious experience is, literally, part of the physical environment. 2 One prima facie difficulty the Causal Theory appears to face is the problem of deviant causal chains, of providing sufficient conditions for perception; I shall not address this difficulty directly, though some of my concluding remarks will bear on it. My main aim in this paper is to show that, despite the deviant causal chains problem, the Causal Theory is to be preferred to the rival Disjunctive View

Abstract: This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philosophical constraints, as enumerated and discussed in Section 1 below. A perceptual theory invoking _reflexive dispositions_--that is, dispositions directed toward the very same worldly perceived objects or properties that caused them--will be defended as one legitimate such naturalistic theory

Abstract: The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of informational concepts. However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views

Abstract: Causal theories of perception typically have problems in explaining deviant causal chains. They also have difficulty with other unusual putative cases of perception involving prosthetic aids, defective perception, scientifically extended cases of perception, and so on. But I show how a more adequate reflexive causal theory, in which objects or properties X cause a perceiver to acquire X-related dispositions toward that very same item X, can provide a plausible and principled perceptual explanation of all of these kinds of cases. A critical discussion of David Lewis's perceptual descriptivist views is also provided, including a defense of the logical possibility of systematic misperception or perceptual error for a perceiver, in spite of its empirical improbability

Abstract: In this book Gerald Vision argues for a new causal theory, one that engages provocatively with direct realism and makes no use of a now discredited subjectivism

Abstract: 1. Introduction. Like other direct realists, Thomas Reid offered an alternative to indirect realist and idealist accounts of perception. Reids alternative aimed to preserve the indirect realists commitment to realism about the objects of perception, and the idealists commitment to the immediacy of the minds relation to the objects of perception. Reid holds that what you perceive is mind independent or external; and your relation to such objects in perception is direct or immediate. In his own words, something which is extended and solid, which may be measured and weighed, is the immediate object of my touch and sight. And this object I take to be matter, and not an idea (IP II xi, 154)

Abstract: Since the 1970s, Michael Turvey, Robert Shaw, and William Mace have worked on the formulation of a philosophically-sound and empirically-tractable version of James Gibson

Abstract: Thomas Reid thought of himself as a critic of the representative theory of perception, of what he called the ‘theory of ideas’ or ‘the ideal theory’.2 He had no kind words for that theory: “The theory of ideas, like the Trojan horse, had a specious appearance both of innocence and beauty; but if those philosophers had known that it carried in its belly death and destruction to all science and common sense, they would not have broken down their walls to give it admittance.”3 Many have supposed that his opposition to the representative theory was grounded in his direct realism.4 A direct realist theory of perception holds that perception of external objects is not mediated by any mental entity whose intrinsic character licenses a move from the mental entity to the external object presented in perception. Reid himself, in an oration of 1759, delivered at graduation ceremonies over which he presided as regent and professor of philosophy at King’s College in Aberdeen, said that he did not “understand what need there is of an intermediate object for thought about something to be possible.”5 Hence, if Reid was not a direct realist, philosophers and historians would have to ask whether and to what degree Reid was what he thought himself to be

Abstract: This paper comments on Gallagher’s recently published direct perception proposal about social cognition [Gallagher, S. (2008a). Direct perception in the intersubjective context. Consciousness and Cognition, 17(2), 535–543]. I show that direct perception is in danger of being appropriated by the very cognitivist accounts criticised by Gallagher (theory theory and simulation theory). Then I argue that the experiential directness of perception in social situations can be understood only in the context of the role of the interaction process in social cognition. I elaborate on the role of social interaction with a discussion of participatory sense-making to show that direct perception, rather than being a perception enriched by mainly individual capacities, can be best understood as an interactional phenomenon.

Abstract: How can it be true that one sees a lake when looking at a picture of a lake, since one's gaze is directed upon a flat dry surface covered in paint? An adequate contemporary explanation cannot avoid taking a theoretical stand on some fundamental cognitive science issues concerning the nature of perception, of pictorial content, and of perceptual reference to items that, strictly speaking, have no physical existence. A solution is proposed that invokes a broadly functionalist, naturalistic theory of perception, plus a double content analysis of perceptual interpretation, which permits non-supervenient, culturally autonomous modes of reference to be generated and artistically exploited even in a purely physical world. In addition, a functionalist concept of broad or 'spread' reference replaces the traditional precise intentional concept of reference, which previously made reference to non-existent items theoretically intractable

Abstract: When philosophers speak of direct perceptual knowledge, they obviously mean to suggest that such knowledge is unmediated ? but unmediated by what? This is where we find evidence of violent disagreement. To clarify matters, I want to identify and briefly describe several important senses of "direct" that have helped shape our understanding of perceptual knowledge. They are (1) "Direct" as Non-Inferential Perception; (2) "Direct" as Unmediating by Objects of Perception; (3) "Direct" as Conceptually Unmediated Perception; (4) "Direct" as Independent Verification of Perceptual Beliefs; and (5) "Direct" as Perception of What is Epistemically Prior

Abstract: I defend a view of the structure of visual property-awareness by considering the phenomenon of perceptual constancy. I argue that visual property-awareness is a three-place relation between a subject, a property, and a manner of presentation. Manners of presentation mediate our visual awareness of properties without being objects of visual awareness themselves. I provide criteria of identity for manners of presentation, and I argue that our ignorance of their intrinsic nature does not compromise the viability of a theory that employs them. In closing, I argue that the proposed manners of presentation are consistent with key direct-realist claims about the structure of visual awareness.
