The Nature of Perceptual Experience, Misc

This article argues that the Representation is drawn by the perceiver: that it does not arrive at the visual cortex fully-formed. Rather, colour arrives at the visual cortex and the Representation is drawn from that.

Some metaphysics are provided showing that what is commonly called ‘the physical world’ can be deconstructed into three ‘levels’: a single, unified ‘noumenal world’ on which everything supervenes; a ‘phenomenal world’ that we each privately experience through direct perception of phenomena; and a ‘collective world’ that people in any given ‘language using group’ experience through learning, using and adapting that group’s language. This deconstruction is shown to enable a clear account of qualia and of how people can hold some things (...) to be physically real even when it is clear no one can ever directly experience those things as phenomena. It is further shown to enable a single, internally consistent, largely empirically supported conceptual framework – a ‘metacosmology’ – able to encompass not only the physical world as people conceive of it for everyday purposes, and as scientists conceive of it for scientific purposes, but also people’s first person phenomenal experience of a physical world and, prospectively, the mechanisms by which such first person, conscious experiences can be generated.

I give an account of sensory presentation, an indispensable and irreducible element of perceptual experience, in terms of the principle of sympathy. Haptic touch, audition, and vision are compared.

I raise a puzzle about the 'phenomenological particularity' of hallucination. It seems possible for it to appear to a hallucinator that a particular object is present though no object is. But I show how difficult this is to sustain. I argue that if it seems a particular object is present, there must be an object that seems present. So if a hallucination has phenomenological particularity, it must be of an object.

The main question that we address in this chapter is what to say about reportedly libertarian experiences of free agency – in other words, experiences of options as being open, and up to oneself to decide among, such that, if they are accurate or veridical, then (at a minimum) indeterminism must be true. A great deal rides on this question. If normal experiences of free agency are libertarian, and if compatibilists cannot explain them away, then all of us may be (...) under systematic illusion at almost every moment of our waking lives. That is, our experiences would be illusory if humans do not in fact satisfy libertarian conditions (e.g., if indeterminism does not occur in the right time or place during decision-making, or we lack agent-causal powers). In some sense, more rides on the question of whether we are agents of the sort that we experience ourselves as being than on the question of whether we have the type of control required for moral responsibility. At worst, we are not responsible in only one sense if we lack what libertarians say we need. Yet even then, we would not be under systematic experiential illusion during most of our waking lives, as we are if our experience is libertarian, yet false. (shrink)

Theories of consciousness divide over whether perceptual consciousness is rich or sparse in specific representational content and whether it requires cognitive access. These two issues are often treated in tandem because of a shared assumption that the representational capacity of cognitive access is fairly limited. Recent research on working memory challenges this shared assumption. This paper argues that abandoning the assumption undermines post-cue-based “overflow” arguments, according to which perceptual conscious is rich and does not require cognitive access. Abandoning it also (...) dissociates the rich/sparse debate from the access question. The paper then explores attempts to reformulate overflow theses in ways that don’t require the assumption of limited capacity. Finally, it discusses the problem of relating seemingly non-probabilistic perceptual consciousness to the probabilistic representations posited by the models that challenge conceptions of cognitive access as capacity-limited.

This is an unedited version of a paper written in 2012 accepted for publication in a forthcoming Festschrift for Mark Platts. In it I argue that the Helmholtz/Bayes tradition of free energy neuroscience begun by Geoffrey Hinton and his colleagues, and now being carried forward by Karl Friston and his, can be seen as a fulfilment of the Quine/Davidson program of radical interpretation, and also of Quine’s conception of a naturalized epistemology. -/- This program, in turn, is rooted in Helmholtz’s (...) scientific reconception of Kant’s notion of a concept-led synthesis of affectations by an extra-sensory reality that creates human self-consciousness, a topic previously discussed in my (2012) Psychoanalysis, Representation, and Neuroscience. -/- I also argue that 20th century analytical philosophy went astray when Frege, Russell, and Wittgenstein ignored their legacy from Helmholtz and espoused a conception of perception and epistemology that he had already shown to be false.

This is a response to Marie McGinn, who, roughly, lined me up with J. L. Austin over against GEM Anscombe and Wittgenstein on the issue whether perception is (or can be) intentional. I do not mind being aligned with Austin, but argue that this is the wrong way to line things up. I stand equally with Wittgenstein. Anscombe turns out to be odd man out on this one.

This paper argues for a theory of phenomenal intentionality (herein referred to as ‘Structuralism’), according to which perceptual experiences only possess intentional content when their phenomenal components are appropriately related to one another. This paper responds to the objections (i) that Structuralism cannot explain why some experiences have content while others do not, or (ii) why contentful experiences have the specific contents that they have. Against (i), I argue that to possess content, an experience must present itself as an experience (...) of something distinct from itself, and that only experiences whose components are suitably structured satisfy this requirement. Against (ii), I argue that Structuralists can provide a deeper explanation of perceptual content than other theories of phenomenal intentionality by showing how the content-determining relations among our experiences depend on the selection pressures under which our perceptual systems developed.

This chapter focuses on the controversies surrounding the transparency of experience (or simply transparency), an (alleged) introspective datum that has played a central role in debates on the nature of perceptual experience and phenomenal consciousness. The main emphasis is on issues arising in relation to transparency and introspection, though its significance for the metaphysics of experience is also stressed. First, the chapter outlines Harman’s and Tye’s characterization of transparency and the conclusions they draw about the metaphysics of experience. Next, it (...) discusses the relation between this characterization and introspection by addressing two central questions: first, what picture of introspection is suggested by Harman’s and Tye’s transparency thesis? Second, does introspection genuinely support this thesis? The discussion reveals that Harman’s and Tye’s characterization of transparency relies on substantial and controversial theoretical assumptions that go beyond what can be established on purely (or largely) introspective grounds. In this way, the chapter highlights the main points of disagreement about transparency and, when relevant, their implications for the metaphysics of experience. It concludes by sketching a way of structuring the debate and raising further questions about the genuine pre-theoretical core of transparency and why theoretical supplementation plays such a pivotal role.

One of Edmund Husserl’s signature ideas is that perceptual experience is structured into fulfilled and empty components. When visually inspecting a cup, for example, only some of its exterior and interior fall into your line of sight and to that extent is experienced in “fulfillment.” However, you are perceptually sensitive to the fact that the cup’s exterior and interior exceed what falls into your line of sight. The contents of that sort of awareness are experienced “emptily,” without fulfillment. Husserl’s view (...) that perceptual experience is structured into fulfilled and empty components is the immediate consequence of his thesis that perceptual experience is inherently inadequate. That means, roughly, there is always more to how things are perceptually taken to be than how they are presented. Here I explicate the conceptual pair adequacy/inadequacy, locate it in Husserl’s larger philosophical program, and sketch his rationale for thinking perceptual experience is inherently—always and in every instance—and radically—through and through and in every respect—inadequate. I then present a series of arguments challenging Husserl's conception of perception as radically inadequate and undermining the case for its inherent inadequacy. (shrink)

This paper examines aesthetic experience as the experiential manifestation of evaluation persistence, a structural condition identified in the theory of evaluative bifurcation. In ordinary judgment, detected difference generates a demand for correction that resolves through exclusion or determination. In certain aesthetic cases, however, difference remains present without producing exclusion pressure. Harmony is therefore described as a condition in which evaluation persists while the demand for determination does not arise. Calmness appears as the experiential manifestation of a non-terminating evaluative structure rather (...) than its psychological cause. Because judgment operates where complete determination is not achieved, evaluation does not terminate through exclusion in this case. The evaluative form constrained by this non-excludability is termed compassion, understood not as emotion or virtue but as a structural condition for the persistence of evaluation. Beauty is therefore interpreted as the experiential manifestation of evaluation persistence. (shrink)

In this chapter we will explore new avenues for developing and defending Naïve Realism (also known as Relationalism), understood as a thesis about the phenomenal character of experience. The core claim of Naive Realism is that ‘what it’s like’ for a subject who enjoys a normal, successful perceptual experience of her surroundings consists in her being directly consciously aware of mind-independent entities in her external environment. It is widely agreed that the strongest challenge to Naïve Realism comes from the alleged (...) possibility of total hallucinations, and the orthodox line of response has been to adopt Disjunctivism about perceptual experience. In this chapter, we will instead focus on an emerging alternative family of responses, which we’ll call ‘New Wave Relationalism’ (NWR). The core commitment of NWR is to reject the initial assumption that there can be total hallucinations that are both non-relational and subjectively indistinguishable from genuine perceptions. The primary aim for this chapter will be to explore and defend this broad NWR strategy for responding to the threat posed by hallucinations to Naïve Realism. We will argue that which specific version or species of NWR a Naïve Realist should adopt will depend on their background methodological and metaphysical commitments. (shrink)

The claim that perfect hallucination is introspectively indistinguishable from perception has been a centrepiece of philosophical theorizing about sense experience. The most common interpretation of the indistinguishability claim is modal: that it is impossible to distinguish perfect hallucination from perception through introspection alone. I run through various models of introspection and show that none of them can accommodate the modal interpretation. Rejecting the modal interpretation opens up two alternative interpretations of the indistinguishability claim. According to the generic interpretation, hallucination is (...) indistinguishable from perception despite the existence of possible exceptions, while according to the actuality interpretation, the indistinguishability of hallucination from perception consists in the actual failure to distinguish hallucination from perception. These alternative understandings of the indistinguishability claim have a number of significant implications for the problem of perception, including the rejection of perfect hallucination and illusion in favour of our ordinary, non-philosophical concepts of these states.

A verbal dispute is one in which the disputants agree on all of the facts about the intended subject matter of the dispute and disagree only about how to use certain terms. This paper explores the possibility that the dispute between particularists and generalists about the contents of perceptual experience is a verbal dispute. The aim is less to provide a knockdown argument for the conclusion that this dispute is merely verbal than to show how difficult it is to uncover (...) a substantive dispute between the two sides. A concluding section asks whether the argument generalizes beyond the particularism/generalism dispute to other prominent disputes in contemporary philosophy of mind. (shrink)

Christopher Hill's Perceptual experience is a must‐read for philosophers of mind and cognitive science. Here I consider Hill's representationalist account of spatial perception. I distinguish two theses defended in the book. The first is that perceptual experience does not represent the enduring, intrinsic properties of objects, such as intrinsic shape or size. The second is that perceptual experience does represent certain viewpoint‐dependent properties of objects—namely, Thouless properties. I argue that Hill's arguments do not establish the first thesis, and then I (...) raise questions about the Thouless‐property view and its role in Hill's defense of representationalism. (shrink)

Andrea Kern contends that perceptual experience is perceptual knowledge if our self-consciously held capacity for perceptual knowledge is “perfectly” actualized. I argue that this view requires further justification. First, Kern is unable to support her claim that an awareness of our self-conscious capacity for perceptual knowledge is “contained” in all our perceptions. Second, Kern’s claim that perception includes the idea of the conditions of perception is potentially inconsistent with her denial that perceptual experience enables perceptual knowledge.

I argue that there are no irrational visual experiences, if we mean just the experiences that one is having now, but there are irrational visual experiences, if we mean also the experiences that one has had in the past. In other words, I will be arguing that perceptual irrationality is a retrospective phenomenon. So as to further support the first conjunct of my thesis, and to contextualize it among contemporary discussions, I also critique Susanna Siegel’s proposal that one could be (...) having an irrational experience, in the sense of a hijacked experience that has inherited a sub-threshold epistemic charge from a corrupt outlook. The present discussion is conducted from a Husserlian point of view, according to which perception is rational, rather than arational. I am, however, in this paper, not undertaking to defend the Husserlian view or the rationality of perception, or even to argue that the view I refer to as Husserlian is, in all aspects, the view that Edmund Husserl actually held. I aim merely to provide certain clarifications concerning the more specific topic of irrational visual experiences. (shrink)

I argue that dreams can contain perceptual elements in multifarious, heretofore unthought-of ways. I also explain the difference between dreams that contain perceptual elements, perceptual experiences that contain dream elements, and having a dream and a perceptual experience simultaneously. I then discuss two applications of the resulting view. First, I explain how my taxonomy of perception in dreams will allow “dream engineers”—who try to alter the content of people’s dreams—to accurately classify different dreams and explore creating new forms of perception (...) in dreams. Second, I consider the consequences of the view for the role of memory in dreaming and imagination. I argue that not every element of dreams or sensory imaginations must rely on memory. The resultant view of sensory imagination provides a counterexample to Hume’s account of sensory imagination, according to which sensory imagination must be built up from faint copies of sensory impressions stored in memory.

Thomas Reid famously claimed that our perceptual experiences reveal what primary qualities are in themselves, while providing us with only an obscure notion of secondary qualities. I maintain that this claim is largely correct and that, consequently, any adequate theory of perception must explain the fact that perceptual experiences provide significantly less insight into the nature of secondary qualities than into the nature of primary qualities. I maintain that neither naïve realism nor the standard Russellian variety of the content view (...) can provide a satisfying explanation; instead, in order to provide a satisfying explanation, we must posit that perceptual experiences represent properties via Fregean modes of presentation. Further, I maintain that we must depart from the standard Fregean variety of the content view in two important respects. First, the relevant modes of presentation must be characterized without appealing to causal relations between perceptual experiences and perceived properties; and second, we must posit that primary and secondary qualities are represented via modes of presentation of different kinds. The resulting view is that primary qualities are represented via perceptual modes of presentation analogous to highly detailed descriptions, while secondary qualities are represented via perceptual modes of presentation analogous to impoverished descriptions.

In this paper, I argue that mental types can overlap. That is, one token mental state can be multiple types. In particular, I argue that a perceptual experience can simultaneously be a belief. This does not imply that belief and experience are type-identical, they merely share some of their tokens. When a subject perceives with content _p_, that content is usually accessible to the subject. By endorsing _p_, whether automatically or consciously, the subject comes to believe that _p_. In this (...) instance, the perceptual experience, while retaining its content and phenomenology, becomes a belief. The possibility of this kind of overlap turns out to have epistemic benefits, especially in the face of arguments by Alex Byrne and Kathrin Glüer. I consider several objections to overlap, including the idea that perception and belief have different kinds of content, that beliefs tend to outlast experiences and differences in phenomenology.

ABSTRACT I focus on two of the challenges Pautz raises for representationalist theories of perception. The first is the challenge of explaining the necessity of certain principles which Pautz calls 'laws of appeaeance.' The second is based on the idea that the most promising versions of representationalism seem to lead to irrealism about the sensible qualities.

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on which they (...) have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

Many philosophical debates take for granted that there is such a thing as ‘the’ common-sense conception of the phenomenon of interest. Debates about the nature of perception tend to take for granted that there is a single, coherent common-sense conception of vision, consistent with Direct Realism. This conception is often accorded an epistemic default status. We draw on philosophical and psychological literature on naïve theories and belief fragmentation to motivate the hypothesis that untutored common sense encompasses conflicting Direct Realist and (...) Indirect Realist conceptions: there is no such thing as ‘the’ common-sense conception of vision that could enjoy epistemic default status. To examine this hypothesis, a survey administered an agreement rating task with verbal and pictorial stimuli to lay participants. We found many laypeople simultaneously hold conflicting Direct Realist and Indirect Realist beliefs about vision. Against common assumptions, Direct Realist beliefs are not clearly dominant, and consistent adherence to Direct Realism is not the norm, but the exception. These findings are consistent with recent accounts of belief fragmentation. They forcefully challenge common methodology in philosophical debates about the nature of perception and beyond. (shrink)

Touch is standardly taken to be a proximal sense, principally constituted by capacities to detect proximal pressure and thermal stimulation, and contrasted with the distal senses of vision and audition. It has, however, recently been argued that the scope of touch extends beyond proximal perception; touch can connect us to distal objects. Hence touch generally should be thought of as a connection sense. In this paper, I argue that whereas pressure perception is a connection sense, thermal perception is not. Thermal (...) perception is a proximal sense distinct from touch. One significant consequence of this is that it motivates an alternative explanation of how we detect the thermal properties of the things we touch and what they are. (shrink)

Both John Campbell and Quassim Cassam have argued that we perceptually experience objects as mind-independent (MI), purportedly solving a problem they refer to as “Berkeley’s Puzzle.” In this paper, I will consider the same topic from a Husserlian perspective. In particular, I will clarify the idea of MI and argue that there is, indeed, a sense in which we can perceptually experience objects as MI, while also making objections to Campbell’s and Cassam’s respective arguments to the same effect. In particular, (...) I will argue that objects can be experienced as MI in the sense of the experience’s not being due to the malfunctioning of a perceptual organ, e.g., when one examines the ways in which the object displays itself, and gains confidence that there is, indeed, nothing the matter with one’s eyes. I will address the issue of MI from the perspective of Husserlian evidentialism, according to which perceptual content is conceived in terms of ways of perceptually exploring the object, thereby gaining evidence pertinent to the object and its properties, e.g., as when one takes a look at the object’s shape from a different angle, or scrutinizes its color in better lighting.

Higher animals need to identify and track material objects because they depend on interactions with them for nutrition, reproduction, and social interaction. This paper investigates the perception of material objects. It argues, first, that material objects are tagged, in all five external senses, as bearers of the features detected by them. This happens through a perceptual process, here entitled Generalized Completion, which creates the appearance of objects that have properties that transcend the activation of sensory receptors. The paper shows, secondly, (...) that material objects are privileged subjects for perceived motion and interaction. That is, they are perceived as subjects for these properties while their parts seem to be subjects only derivatively. Material objects are the only perceptual subjects that are both multisensory and privileged. (shrink)

In this chapter, Mary Collins Swabey critiques G. E. Moore's discussion of sense data.

Tomamos como certo que os nossos sentidos nos colocam em contato com o ambiente ao nosso redor. Enquanto caminhamos em uma rua, vemos obstáculos que temos de contornar ou remover. Mesmo de costas, podemos ouvir a bicicleta que se aproxima e dar passagem. Em suma, por meio de experiências perceptivas (visuais, auditivas, olfativas etc.), ficamos conscientes de objetos ou eventos que estejam ocorrendo ao nosso redor. Além disso, com base no que percebemos, podemos formar e manter crenças acerca do ambiente (...) e, assim, adquirir conhecimento perceptivo acerca do mundo. A importância desse conhecimento acerca do que está ao nosso alcance perceptivo é inestimável para a nossa sobrevivência e a condução de nossos projetos cotidianos. Contudo, podemos querer saber (1) se de fato temos acesso ao mundo físico circundante por meio das nossas experiências perceptivas, e (2) se e como essas experiências justificam as nossas crenças acerca do que percebemos. Esses problemas são centrais para a epistemologia da percepção, embora não sejam os únicos. Nessa entrada, abordaremos esses dois problemas. (shrink)

This paper investigates the nature of emotional experience in relation to the senses, and it defends the thesis that emotional experience is partly non-sensory. In §1 I introduce my reader to the debate. I reconstruct a position I call ‘restrictivism’ and motivate it as part of a reductive approach to mind’s place in nature. Drawing on intuitive but insightful remarks on the nature of sensation from Plato, I map out the conditions under which the restrictivist thesis is both substantive and (...) plausible. I then present two arguments against it. The first argument, which I lay out in §2, draws on recent empirical results in emotion research to show that restrictivism cannot be reconciled with the possibility of knowledge of one’s own emotional state by acquaintance. The second argument, which I present in §3, individuates a claim on which most contemporary theories of emotional valence converge and uses it to demonstrate that restrictivism has a false implication: it must deny that valence is experientially felt.

This paper defends the idea that phenomenological approaches to self-consciousness can enrich the current analytic philosophy of perception, by showing how phenomenological discussions of minimal self-consciousness can enhance our understanding of the phenomenology of conscious perceptual experiences. As a case study, I investigate the nature of the relationship between naïve realism, a contemporary Anglophone theory of perception, and experiential minimalism (or, the ‘minimal self’ view), a pre-reflective model of self-consciousness originated in the Phenomenological tradition. I argue that naïve realism is (...) not only compatible with, but can be supplemented with experiential minimalism in a novel way. The suggestion is that there are reasons to combine naïve realism and experiential minimalism. My focus here will be on drawing a connection between the notion of minimal self and two core theoretical commitments of naïve realism, relationalism and transparency. (shrink)

While the view that we perceive aesthetic properties may seem intuitive, it has received little in the way of explicit defence. It also gives rise to a puzzle. The first strand of this puzzle is that we often cannot perceive aesthetic properties of artworks without training, yet much aesthetic training involves the acquisition of knowledge, such as when an artwork was made, and by whom. How, if at all, can this knowledge affect our perception of an artwork’s aesthetic properties? The (...) second strand of the puzzle arises when we widen the scope of aesthetic experience. The very same aesthetic properties that seem to require training for their perception in artworks do not appear to require training to perceive in objects of everyday aesthetic appreciation and natural phenomena. In this paper I argue that a prominent extant attempt to explain how training is compatible with aesthetic perception—cognitive permeation—is an inadequate solution. I also develop a positive view of aesthetic perception that provides a unified solution to both strands of the puzzle. (shrink)

The debate between relationalism and representationalism in the philosophy of perception seems to have come to a standstill where opponents radically disagree on methodological principles or fundamental assumptions. According to Fish (this volume) this is because, not unlike Kuhnian scientific paradigms, the debate displays some elements of incommensurability. This diagnosis makes advancing the debate impossible. I argue that what is hindering progress is not a clash of research programmes, but a series of misunderstandings that can be avoided by disentangling the (...) different questions each theory is invested in and by making explicit the hidden assumptions at play in the debate. One such central assumption is what I call the Superficiality Constraint. This is the idea that the phenomenal character of experience is superficial with respect to introspection. I argue that we can make progress in the debate by assessing to what extent and at what cost relationalism can accommodate this constraint. (shrink)

There is, of course, The Given: what is given in experience. The ‘Myth Of The Given’ is just a wrong answer to the question ‘What is given?’ This paper offers a brief sketch of three possible right answers. It examines an early account by Charles Augustus Strong of why The Myth is a myth. It maintains that a natural and naturalistic version of empiricism is compatible with the fact that the Myth is a myth. It gives proper place to enactivist (...) considerations. It is ) broadly in line with the Sellarsian view as refined by John McDowell. It meets an important constraint: acknowledging the reality of something that seems at first to lend support to The Myth—i.e. the fact that we can engage in ‘non-inferential self-attribution of … sensations’ —without in any way succumbing to the Myth.

The dual role of olfaction in both smelling and tasting, i.e. flavour perception, makes it an important test case for philosophical theories of sensory individuation. Indeed, the psychologist Paul Rozin claimed that olfaction is a “dual sense”, leading some scientists and philosophers to propose that we have not one, but two senses of smell: orthonasal and retronasal olfaction. In this paper I consider how best to understand Rozin’s claim, and upon what grounds one might judge there to be one or (...) two distinct olfactory modalities. I conclude that while Rozin may be right that humans have dual occurrences of an olfactory ‘sense’, the concept of a sense-modality, and hence the ‘sense’ of smell, is ambiguous between two different notions: a physiological sensory channel and an experiential modality, along the lines suggested by J. J. Gibson. Furthermore, recognising that these are complementary rather than competing conceptions of a sense-modality enables the formulation of a powerful ‘dual-concept’ framework for posing and addressing questions concerning the complex architecture of human multisensory experience.

This chapter focuses on the relationship between consciousness and knowledge, and in particular on the role perceptual consciousness might play in justifying beliefs about the external world. We outline a version of phenomenal dogmatism according to which perceptual experiences immediately, prima facie justify certain select parts of their content, and do so in virtue of their having a distinctive phenomenology with respect to those contents. Along the way we take up various issues in connection with this core theme, including the (...) possibility of immediate justification, the dispute between representational and relational views of perception, the epistemic significance of cognitive penetration, the question of whether perceptual experiences are composed of more basic sensations and seemings, and questions about the existence and epistemic significance of high-level content. In a concluding section we briefly consider how some of the topics pursued here might generalize beyond perception. (shrink)

The chapter is comprised of five sections. First, it situates knowledge and epistemic warrant in a frame of representational and epistemic norms. It distinguishes two types of epistemic warrant–entitlement (warrant without reason) and justification (warrant through reason). Second, it argues that epistemic internalism—according to which epistemic warrant supervenes on psychological states of the warranted individual—is unacceptable. Third, it discusses the status of scepticism in epistemology. Fourth, it criticizes an argument that believing that we are entitled to perceptual beliefs would commit (...) us to an unacceptable way of validating the reliability of those beliefs. Fifth, it rebuts an argument that believing that we are entitled to perceptual beliefs is inconsistent with intuitions about confirmation and with Bayesian principles of subjective probability.

A commonly-discussed feature of perceptual experience is that it has ‘assertoric’ or ‘phenomenal’ force. We will start by discussing various descriptions of the assertoricity of perceptual experience. We will then adopt a minimal characterization of assertoricity: a perceptual experience has assertoric force just in case it inclines the perceiver to believe its content. Adducing cases that show that visual experience is not always assertoric, we will argue that what renders these visual experiences non-assertoric is that they are penetrated by belief-like (...) imaginings. Lastly, we will explain why it is that when belief-like imaginings—as opposed to beliefs (and other cognitive states)—penetrate visual experience, they render visual experiences non-assertoric.

Victor Vasarely's (1906–1997) important legacy to the study of human perception is brought to the forefront and discussed. A large part of his impressive work conveys the appearance of striking three-dimensional shapes and structures in a large-scale pictorial plane. Current perception science explains such effects by invoking brain mechanisms for the processing of monocular (2D) depth cues. Here in this study, we illustrate and explain local effects of 2D color and contrast cues on the perceptual organization in terms of figure-ground (...) assignments, i.e. which local surfaces are likely to be seen as “nearer” or “bigger” in the image plane. Paired configurations are embedded in a larger, structurally ambivalent pictorial context inspired by some of Vasarely's creations. The figure-ground effects these configurations produce reveal a significant correlation between perceptual solutions for “nearer” and “bigger” when other geometric depth cues are missing. In consistency with previous findings on similar, albeit simpler visual displays, a specific color may compete with luminance contrast to resolve the planar ambiguity of a complex pattern context at a critical point in the hierarchical resolution of figure-ground uncertainty. The potential role of color temperature in this process is brought forward here. Vasarely intuitively understood and successfully exploited the subtle context effects accounted for in this paper, well before empirical investigation had set out to study and explain them in terms of information processing by the visual brain.

If you want to understand McDowell's spatial metaphors when he talks about perceptual knowledge, place him side-by-side with Dretske on perceptual knowledge. Though McDowell shows no evidence of reading Dretske's writings on knowledge from the late 1960s onwards (McDowell mentions "Epistemic Operators" once in passing), McDowell gives the same four arguments as Dretske for the conclusion that knowledge requires "conclusive" reasons that rule of the possibility of mistake. Despite various differences, we think it is best to read McDowell as re-discovering (...) Dretske on perceptual knowledge. Since Dretske is easy to understand, all of McDowell's metaphors become easy to understand. But what about McDowell's disjunctivism? Turns out McDowell is not an ontological disjunctivist, and his epistemological disjunctivism is really just the banal point that some perceptual experiences provide conclusive reasons for perceptual belief and some do not. Perceptual experiences are either conclusive or inconclusive. Dretske would agree. (shrink)

In this paper, I propose a Husserlian account of perceptual confidence, and argue for perceptual confidence by appeal to the self-justification of perceptual experiences. Perceptual confidence is the intriguing view, recently developed by John Morrison, that there are not just doxastic confidences but also perceptual confidences, i.e., confidences as aspect of perceptual experience, enabling us to account, e.g., for the increasing confidence with which we experience an approaching human figure, while telling ourselves, as the viewing distance diminishes, “It looks like (...) this just could be Isaac”, “It looks like this is probably Isaac”, “It looks like this is almost certainly Isaac”. I first present my Husserlian account with a focus on the notion of fulfillment, and the idea that the contents of perceptual experience are fulfillment conditions. I then show that this account can be complemented by PC. Finally, I develop a focus on the idea of perceptual self-justification, diverting the perceptual confidence debate from its pre-eminent concern with the relations between perceptual and doxastic confidences, and present an argument to the effect that there are perceptual confidences.

Nearly everyone agrees that perception gives us justification and knowledge, and a great number of epistemologists endorse a particular two-part view about how this happens. The view is that perceptual beliefs get their justification from perceptual experiences, and that they do so by being based on them. Despite the ubiquity of these two views, I think that neither has very much going for it; on the contrary, there’s good reason not to believe either one of them.

In two papers, Ned Block has argued that representationalists have trouble with the empirical discovery that differences in the degree of visual attention to an object can lead to a difference in h...

According to some philosophers, when introspectively attending to experience, we seem to see right through it to the objects outside, including their properties. This is called the transparency of experience. This paper examines whether, and in what sense, emotions are transparent. It argues that emotional experiences are opaque in a distinctive way: introspective attention to them does not principally reveal non-intentional somatic qualia but rather felt valenced intentional attitudes. As such, emotional experience is attitudinally opaque.

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

Entry in Routledge handbook of skill and expertise. Discusses social perception, perceptual expertise, knowing what things look like, and a bit about about aesthetics at the end.
