Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual error can help (...) to make good sense of both of Aristotle’s claims. (shrink)

There has been a recent surge in interest in two questions concerning the nature of perceptual experience; viz. the question of whether perceptual experience is sometimes cognitively penetrated and that of whether high-level properties are presented in perceptual experience. Only rarely have thinkers been concerned with the question of whether the two phenomena are interestingly related. Here we argue that the two phenomena are not related in any interesting way. We argue further that this lack of an interesting connection between (...) the two phenomena has potentially devastating consequences for naïve realism. Finally, we consider the possibility of a disunified view of experience that takes perceptual experience to be a matter of both being directly perceptually related to mind-independent objects and property instances as well as consciously representing these entities.

Siegel and Byrne debate whether perceptual experiences present rich properties or exclusively thin properties.

I give some reasons to think that perceptual experiences redound on the rational standing of the subject, and explore the consequences of this idea for the global structure of justification.

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)

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you are prevented from perceiving (...) properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected.

According to orthodoxy, perceptual beliefs are caused by perceptual experiences. The paper argues that this view makes it impossible to explain how experiences can be epistemically significant. A rival account, on which experiences in the “good case” are ways of knowing, is set out and defended.

Which properties can we visually experience? Some authors hold that we can experience only low-level properties such as color, illumination, shape, spatial location, and motion. Others believe that we can also experience high-level properties, such as being a dog or being a pine tree. On the basis of her method of phenomenal contrast, Susanna Siegel has recently defended the latter view. One of her central claims is that we can best account for certain phenomenal contrasts if we assume that we (...) can visually experience natural kind properties. In this paper, I argue that certain kinds of low-level properties, namely shape-gestalt properties, can explain these phenomenal contrasts just as well as high-level properties. If successful, this is a modest, but nevertheless significant result. Even though it does not prove the falsity of Siegel’s proposal, it nevertheless secures the existence of a plausible alternative.

I propose that there are two kind's of qualia realism, and that Harman's observations about the transparency of experience pose a threat to only one of these.

Naïve realism, often overlooked among philosophical theories of perception, has in recent years attracted a surge of interest. Broadly speaking, the central commitment of naïve realism is that mind-independent objects are essential to the fundamental analysis of perceptual experience. Since the claims of naïve realism concern the essential metaphysical structure of conscious perception, its truth or falsity is of central importance to a wide range of topics, including the explanation of semantic reference and representational content, the nature of phenomenal consciousness, (...) and the basis of perceptual justification and knowledge. One of the greatest difficulties surrounding discussions of naïve realism, however, has been lack of clarity concerning exactly what affirming or denying it entails. In particular, it is sometimes unclear how naïve realism is related to the claim that perceptual experience is in some sense direct or unmediated, and also to what extent the view is compatible with another widely discussed thesis in the philosophy of perception, the claim that perceptual experiences are states with representational content. In this essay, I discuss how recent work on these issues helps to clarify both the central commitments of naïve realism, as well as its relation to representationalist theories of perception. Along the way, I will attempt to shed light on the different ways in which each approach tries to address the various theoretical challenges facing a philosophical theory of perception, and also to assess the prospects for views that attempts to combine features of each approach.

[This is the penultimate version, please send me an email for the final version]. Some sensations are pleasant, some unpleasant, and some are neither. Furthermore, those that are pleasant or unpleasant are so to different degrees. In this essay, I want to explore what kind of a difference is the difference between these three kinds of sensations. I will develop a comprehensive three-level account of sensory pleasure that is simultaneously adverbialist, functionalist and is also a version of a satisfied experiential-desire (...) account.

It is natural to assume that the fine-grained and highly accurate spatial information present in visual experience is often used to guide our bodily actions. Yet this assumption has been challenged by proponents of the Two Visual Systems Hypothesis , according to which visuomotor programming is the responsibility of a “zombie” processing stream whose sources of bottom-up spatial information are entirely non-conscious . In many formulations of TVSH, the role of conscious vision in action is limited to “recognizing objects, selecting (...) targets for action, and determining what kinds of action, broadly speaking, to perform” . Our aim in this study is to show that the available evidence not only fails to support this dichotomous view but actually reveals a significant role for conscious vision in motor programming, especially for actions that require deliberate attention.

Some sensory experiences are pleasant, some unpleasant. This is a truism. But understanding what makes these experiences pleasant and unpleasant is not an easy job. Various difficulties and puzzles arise as soon as we start theorizing. There are various philosophical theories on offer that seem to give different accounts for the positive or negative affective valences of sensory experiences. In this paper, we will look at the current state of art in the philosophy of mind, present the main contenders, critically (...) compare and contrast them. In particular, we want to examine how they handle the reason-giving power of affective states. We will look into two representationalist proposals (Evaluativism and Imperativism) and a functionalist proposal, and argue that, contrary to their own advertisements, the representationalist proposals don’t have good accounts of why and how sensory affect can motivate, rationalize, and justify subsequent behavior and intentional mental activity. We will show that our own functionalist proposal does a much better job in this regard, and that when the representationalist proposals are modified to do a better job, they fare better not because of their representationalist credentials but due to their functionalist ones.

One of the central debates in contemporary Kant scholarship concerns whether Kant endorses a “conceptualist” account of the nature of sensory experience. Understanding the debate is crucial for getting a full grasp of Kant's theory of mind, cognition, perception, and epistemology. This paper situates the debate in the context of Kant's broader theory of cognition and surveys some of the major arguments for conceptualist and non-conceptualist interpretations of his critical philosophy.

In recent work, Michael Tye has criticized a certain sort of representationalist view of experience for holding that phenomenal characters are properties of experiences. Instead, Tye holds that phenomenal character is 'out there in the world.' This paper has two aims. One is to argue for the somewhat surprising conclusion that Tye’s apparently radical new view is not a change in view at all, but a notational variant of a standard representationalist theory. My more general aim, though, is to lay (...) out a bit more clearly than is usually done the basic metaphysics of representationalist views of consciousness. In the end, what I argue is that unclarity on this score is what has permitted the choice between standard representationalist theories and Tye’s new position to appear to be something more than a verbal question. I conclude by discussing the bearing of this on the question of whether we can be aware of phenomenal character in introspection, and the relative importance of properties of subjects and properties of experiences in the theory of consciousness.

In this paper, I argue that the conscious awareness one has of oneself as acting, i.e., agentive awareness, is not a type of sensory awareness. After providing some set up in Sect. 1, I move on in Sect. 2 to sketch a profile of sensory agentive experiences as representational states with sensory qualities by which we come to be aware of ourselves as performing actions. In Sect. 3, I critique two leading arguments in favor of positing such sensory experiences: the (...) argument from pathology and the argument from cognitive impenetrability. Since neither of these arguments succeeds, the case for positing SAEs is dealt a significant blow. I proceed in Sect. 4 to advance my positive argument against SAEs. The argument runs as follows: If SAEs exist, then they must exist in some sensory modality or set of sensory modalities. Either the relevant sensory modalities are ones that we already recognize, or they are novel sensory modalities. I will argue that neither of these options is workable, and so we have nowhere to locate SAEs. Agentive awareness is not sensory awareness. (shrink)

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

Several philosophers think there are important analogies between emotions and perceptual states. Furthermore, considerations about the rational assessibility of emotions have led philosophers—in some cases, the very same philosophers—to think that the content of emotions must be propositional content. If one finds it plausible that perceptual states have propositional contents, then there is no obvious tension between these views. However, this view of perception has recently been attacked by philosophers who hold that the content of perception is object-like. I shall (...) argue for a view about the content of emotions and perceptual states which will enable us to hold both that emotional content is analogous to perceptual content and that both emotions and perceptual states can have propositional contents. This will involve arguing for a pluralist view of perceptual content, on which perceptual states can have both contents which are proposition-like and contents which are object-like. I shall also address two significant objections to the claim that emotions can have proposition-like contents. Meeting one of these objections will involve taking on a further commitment: the pluralist account of perceptual content will have to be one on which the contents of perception can be non-conceptual.

Call the idea that states of perceptual awareness have intentional content, and in virtue of that aim at or represent ways the world might be, the ‘Content View.’ I argue that though Kant is widely interpreted as endorsing the Content View there are significant problems for any such interpretation. I further argue that given the problems associated with attributing the Content View to Kant, interpreters should instead consider him as endorsing a form of acquaintance theory. Though perceptual acquaintance is controversial (...) in itself and in attribution to Kant, it promises to make sense of central claims within his critical philosophy. (shrink)

Critical discussion of Susanna Schellenberg's account of hallucination and perceptual evidence.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

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)

Representationalism is the view that the phenomenal character of experiences is identical to their representational content of a certain sort. This view requires a strong transparency condition on phenomenally conscious experiences. We argue that affective qualities such as experienced pleasantness or unpleasantness are counter-examples to the transparency thesis and thus to the sort of representationalism that implies it.

I give an account of the difference between "Holistic" and "Atomistic" views of conscious experience. On the Holistic view, we enjoy a unified "field" of awareness, whose parts are mere modifications of the whole, and therefore owe their existence to the whole. There is some tendency to saddle those who reject the Holistic field model with a (perhaps) implausible "building block" view. I distinguish a number of different theses about the parts of an experience that are suggested by the "building (...) block" metaphor, but which can be rejected by those who also reject the holistic field view.

Whither the philosophy of intuition?Herman Cappelen’s Philosophy Without Intuitions (PWI) is a novel study in philosophical sociology—or, as Cappelen at one point suggests, “intellectual anthropology” (96).All undated references are to Cappelen (2012). Its target is the thesis that intuition is central, in the descriptive sense that contemporary analytic philosophers rely on intuitions for evidence—or, more generally, positive epistemic status. Cappelen labels the target thesis Centrality.If Centrality is true, then especially urgent are two questions in the rapidly growing field that is (...) the philosophy of intuition:[Q1] What are intuitions?[Q2] Can intuitions serve as evidence?There are of course others, but in chapter one Cappelen singles out these two as The Burning Questions about intuition. He then summarizes the overall upshot of PWI as follows:In this book I argue that Centrality, on any reasonable interpretation, is false. If you share that view, the Burning Questions will no lo ..

I argue that perceptual experience provides us with both phenomenal and factive evidence. To a first approximation, we can understand phenomenal evidence as determined by how our environment sensorily seems to us when we are experiencing. To a first approximation, we can understand factive evidence as necessarily determined by the environment to which we are perceptually related such that the evidence is guaranteed to be an accurate guide to the environment. I argue that the rational source of both phenomenal and (...) factive evidence lies in employing perceptual capacities that we have in virtue of being perceivers. In showing that both kinds of evidence have the same rational source, I provide a unified account of perceptual evidence and its rational source in perceptual experience. (shrink)

Recent debates between representational and relational theories of perceptual experience sometimes fail to clarify in what respect the two views differ. In this essay, I explain that the relational view rejects two related claims endorsed by most representationalists: the claim that perceptual experiences can be erroneous, and the claim that having the same representational content is what explains the indiscriminability of veridical perceptions and phenomenally matching illusions or hallucinations. I then show how the relational view can claim that errors associated (...) with perception should be explained in terms of false judgments, and develop a theory of illusions based on the idea that appearances are properties of objects in the surrounding environment. I provide an account of why appearances are sometimes misleading, and conclude by showing how the availability of this view undermines one of the most common ways of motivating representationalist theories of perception.

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

I distinguish between two kinds of selection effects on experience: selection of objects or features for experience, and anti-selection of experiences for cognitive uptake. I discuss the idea that both kinds of selection effects can lead to a form of confirmation bias at the level of perception, and argue that when this happens, selection effects can influence the rational role of experience.

The unpleasantness of pain motivates action. Hence many philosophers have doubted that it can be accounted for purely in terms of pain’s possession of indicative representational content. Instead, they have explained it in terms of subjects’ inclinations to stop their pains, or in terms of pain’s imperative content. I claim that such “noncognitivist” accounts fail to accommodate unpleasant pain’s reason-giving force. What is needed, I argue, is a view on which pains are unpleasant, motivate, and provide reasons in virtue of (...) possessing content that is indeed indicative, but also, crucially, evaluative.

Representationalism is, roughly, the view that experiencing is to be analyzed wholly in terms of representing. But what sorts of properties are represented in experience? According to a prominent form of representationalism, objective representationalism, experiences represent only objective (i.e. suitably mind-independent) properties. I explore subjective representationalism, the view that experiences represent at least some subjective (i.e. suitably mind-dependent) properties. Subjective representationalists, but not objective representationalists, can accommodate cases of illusion-free phenomenal inversion. Moreover, subjective representationalism captures the so-called transparency of experience, (...) as it is standardly articulated, just as well as objective representationalism. (shrink)

This is the written version of a reply to Michael Tye's "Transparency, Qualia Realism, and Representationalism," given at the 40th Oberlin Colloquium in Philosophy. It argues that, given one standard way of understanding these theses, qualia realism is trivially true and transparency theses are trivially false. I also discuss four objections to Tye's claim that the phenomenal character of the experience of red just is redness, and conclude by arguing that philosophers of perception should state their claims as about the (...) properties of subjects of experience rather than as about the properties of experiences themselves.

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism. (shrink)

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

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

I argue that an analogy between pains and sounds suggests a way to give an objective account of pain which fits well with a naïve perceptualist account of feeling pain. According to the proposed metaphysical account, pains are relational physical events with shared qualitative nature, each of which is constituted by tissue damage and the activation of nociceptors. I proceed to show that the metaphysical proposal is compatible with platitudes about pains being animate, private, and self-intimating states.

Ordinary use of empty names encompasses a variety of different phenomena, including issues in semantics, mental content, fiction, pretense, and linguistic practice. In this paper I offer a novel account of empty names, the cognitive theory, and show how it offers a satisfactory account of the phenomena. The virtues of this theory are based on its strength and parsimony. It allows for a fully homogeneous semantic treatment of names coped with ontological frugality and empirical and psychological adequacy.

A coin rotating back in depth in some sense presents a changing, elliptical shape. How are we to understand such (in this case) ‘appearances of ellipticality’? How is the experiential sense of such shifting shape appearances related to the experiential sense of enduring shape definitive of perceived shape constancy? Is the experiential recovery of surface shape based on the prior (perhaps more fundamental) recovery of point or element 3D spatial locations?—or is the perception of shape a largely independent perceptual achievement? (...) Do we gain access to enduring shape properties by first detecting and working from ‘shape appearances’? These are some of the topics taken up in this paper. (shrink)

I develop a Russellian representationalist account of size experience that draws importantly from contemporary vision science research on size perception. The core view is that size is experienced in ‘body-scaled’ units. So, an object might, say, be experienced as two eye-level units high. The view is sharpened in response to Thompson’s (forthcoming) Doubled Earth example. This example is presented by Thompson as part of an argument for a Fregean view of size experience. But I argue that the Russellian view I (...) develop handles the Doubled Earth example in a natural and illuminating way, thereby avoiding the need to posit irreducible experiential ‘modes of presentation’. I also address a kind of neo-Fregean ‘reference-fixing’ view of size experience, that shares features with the Russellian view developed. I give reasons for favoring the latter. Finally, I argue that Peacocke’s claim that spatial experience is ‘unit free’ is not persuasive. (shrink)

A direct realist theory of perceptual justification. I take a ground-up approach, beginning with a theory of subjective rationality understood in terms of first-person rational explicability of the stream of consciousness. I mathematize this picture via a Tractarian spin on a semantical framework developed by Rayo. Perceptual states justify by being 'receptive': rationally inexplicable intentional states encoded in sentences that are analytic. Direct realists working within this framework should say that when one is taken in by hallucination one's overall picture (...) of the world is incoherent; in this sense, a belief based on delusive hallucination can be provided with exculpation but not with justification. (shrink)

Students of perception have long puzzled over a range of cases in which perception seems to tell us distinct, and in some sense conflicting, things about the world. In the cases at issue, the perceptual system is capable of responding to a single stimulus — say, as manifested in the ways in which subjects sort that stimulus — in different ways. This paper is about these puzzling cases, and about how they should be characterized and accounted for within a general (...) theory of perception. After rehearsing the sort of case at issue (§1), I’ll examine critically some of the strategies by which philosophers and perceptual psychologists have attempted to account for them (§2). Finally, I’ll present an alternative computational account of the puzzle cases, argue that this view is superior to its competitors, and examine some of its implications (§3). (shrink)

According to proponents of ‘phenomenal holism’, the intrinsic characteristics of the parts of unified conscious states are dependent to some degree on the characteristics of the wholes to which they belong. Although the doctrine can easily seem obscure or implausible, there are eminent philosophers who have defended it, amongst them Timothy Sprigge. In Stream of Consciousness (2000) I found Sprigge’s case for phenomenal holism problematic on several counts; in this paper I re-assess some of these criticisms. Recent experimental work suggests (...) cross-modal perceptual interference may be far more prevalent than expected. I argue that although these results do lend support to phenomenal holism in one of its guises, they do not support the strong form of holism espoused by Sprigge. I then move on to consider the relevance and impact of certain gestalt-related considerations, and argue that these considerations at best establish that the stronger form of holism applies to some parts of some experiential states, but not to all parts of all states, as Sprigge claims. I then consider a more promising way forward for anyone who wishes to defend an across-the-board holism of the strong variety, arguing that what is required is a form of phenomenal interdependence that is rooted solely in phenomenal unity. I conclude by outlining a case for thinking that an interdependence of this sort is a quite general feature of unified conscious states. (shrink)

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

In this paper I argue that it's possible that the contents of some visual experiences are influenced by the subject's prior beliefs, hopes, suspicions, desires, fears or other mental states, and that this possibility places constraints on the theory of perceptual justification that 'dogmatism' or 'phenomenal conservativism' cannot respect.

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!<br><br>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. <br><br>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. (shrink)

Neuropsychological findings used to motivate the "two visual systems" hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link between the spatial contents of visual experience and the perceiver's bodily actions. In this paper, I review and assess three main sources (...) of evidence for the two visual systems hypothesis. I argue that the best interpretation of the evidence is in fact consistent with both claims. I conclude with some brief remarks on the relation between visual consciousness and rational agency.
