The Nature of Perceptual Experience

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

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.

This paper trials new experimental methods for the analysis of natural language reasoning and the development of critical ordinary language philosophy in the wake of J.L. Austin. Philosophical arguments and thought experiments are strongly shaped by default pragmatic inferences, including stereotypical inferences. Austin suggested that contextually inappropriate stereotypical inferences are at the root of some philosophical paradoxes and problems, and that these can be resolved by exposing those verbal fallacies. This paper builds on recent efforts to empirically document inappropriate stereotypical (...) inferences that may drive philosophical arguments. We demonstrate that previously employed questionnaire-based output measures do not suffice to exclude relevant confounds. We then report an experiment that combines reading time measurements with plausibility ratings. The study seeks to provide evidence of inappropriate stereotypical inferences from appearance verbs that have been suggested to lie at the root of the influential ‘argument from illusion’. Our findings support a diagnostic reconstruction of this argument. They provide the missing component for proof of concept for an experimental implementation of critical ordinary language philosophy that is in line with the ambitions of current ‘evidential’ experimental philosophy.

James of Viterbio is one of the rare medieval authors to sustain a thoroughly innatist philosophy. He borrows from Simplicius the notion of idoneitas (aptitude, predisposition) so as to ground a cognition theory in which external things are not the efficient and formal causes of mental acts. A predisposition has the characteristic of being halfway between potentiality and actuality. Therefore, the subject that has predispositions does not need to be acted upon by another thing to actualize them. External things only (...) “incline” the mind to make use of a stock of cognitive schemes. Consequently, in order to avoid an infinite regress James must adopt innatism. Following the lead of late Neoplatonism, he goes as far as including, not only conceptual schemes, but also perceptual schemes among the inbuilt stock. As a result, James’s theory, while it echoes certain preoccupations and themes that are common in the thirteenth century, proves to be one of a kind. (shrink)

Relationalism maintains that perceptual experience involves, as part of its nature, a distinctive kind of conscious perceptual relation between a subject of experience and an object of experience. Together with the claim that perceptual experience is presentational, relationalism is widely believed to be a core aspect of the naive realist outlook on perception. This is a mistake. I argue that naive realism about perception can be upheld without a commitment to relationalism.

Temporal binding occurs when people observe two events that they believe to be causally connected: They underestimate the length of the interval between those two events, when compared with their estimates of the length of intervals between events they believe to be causally unrelated. I discuss temporal binding in the context of Dennett and Kinsbourne’s (Behavioral and Brain Sciences, 15(2), 183–201, 1992) influential argument levelled at what they call ‘Cartesian Materialism’. In particular, I argue that Dennett and Kinsbourne’s argument trades (...) on a representational conception of perceptual experience, which blurs the boundary between perception and judgement, and that temporal binding can serve as a case study for developing an alternative, relational, conception of perceptual experience and of its relation to judgement. Based on research on the mechanisms underlying temporal binding, I provide an explanation of the phenomenon in which perception and judgement play clearly distinct roles. (shrink)

Despite extensive discussion of naïve realism in the wider philosophical literature, those influenced by the phenomenological movement who work in the philosophy of perception have hardly weighed in on the matter. It is thus interesting to discover that Edmund Husserl’s close philosophical interlocutor and friend, the early twentieth-century phenomenologist Johannes Daubert, held the naive realist view. This article presents Daubert’s views on the fundamental nature of perceptual experience and shows how they differ radically from those of Husserl’s. The author argues, (...) in conclusion, that Daubert’s views are superior to those of Husserl’s specifically in the way that they deal with the phenomenon of perceptual constancy. (shrink)

In his celebrated 1974 essay “What Is It Like to Be a Bat?,” Thomas Nagel stages a human-bat encounter to illustrate and support his claim that “subjective experience” is irreducible to “objective fact”: because Nagel cannot experience the world as a bat does, he will never know what it is like to be one. In Nagel’s account, heterogeneity is figured negatively—as a failure or lack of resemblance—and functions to constrain his knowledge of bats. Today, as white-nose syndrome threatens bat populations (...) across North America, might figuring heterogeneity positively, as a condition of creativity, open up new modes of receptivity and responsiveness to species extinctions? This essay turns to philosophies of becoming and to recent research in the biological sciences to explore this possibility. I suggest that attending to the heterogeneity of experience alerts us to more public dimensions of our being and may thereby work against the tendency to understand and experience ourselves as self-contained and closed off from one another and the world we share in common. This may in turn enhance our sense of entanglement with the events, bodies, and forces on the “outside” of experience, including bats and the white-nose syndrome with which they are afflicted today. Such an affirmation of heterogeneity as a condition of creativity holds the greatest promise for multispecies ethics today, I propose, when it is joined to an affirmation of incompatibilities within and between things as a real force of suffering and destruction in a heterogeneous world.

This paper presents a neglected philosophical approach, redevelops it on fresh empirical foundations, and seeks to bring out that it is of not merely historical interest. Building on ideas Ludwig Wittgenstein mooted in the early 1930s, Friedrich Waismann developed a distinctive metaphilosophy: Through case studies on particular philosophical problems, he identified a characteristic structure and genesis displayed by several philosophical problems and presented a distinctive dialogical method for dissolving problems of this kind. This method turns on exposing the need to (...) endow philosophical questions or claims with more determinate meaning and meeting this need by proposing linguistic rules and explanations which the problems’ proponents are free to accept or reject. The approach is embedded in the view that unconscious thought decisively shapes the formulation of philosophical problems. This paper first presents the approach on the basis of Waismann’s texts and then redevelops it through a case study on the ‘problem of perception’ and within a post-Freudian conception of unconscious thought: We will draw on psycholinguistic findings about automatic inferences in language comprehension and production, to examine how unconscious cognition shapes the problem formulation. Findings provide fresh, empirical foundations for the approach which has advantages over more familiar critical projects in ordinary language philosophy, to which it is kindred in spirit. (shrink)

Most contemporary theorists regard the traditional thesis that perception is essentially conscious as just another armchair edict to be abandoned in the wake of empirical discovery. Here I reconsider this dramatic departure from tradition. My aim is not to recapture our prelapsarian confidence that perception is inevitably conscious (though much I say might be recruited to that cause). Instead, I want to problematize the now ubiquitous belief in unconscious perception. The paper divides into two parts. Part One is more purely (...) philosophical. It explains how standard arguments for unconscious perception rely on contentious background assumptions concerning the relation between ordinary perception and the explanatory constructs of scientific psychology. Part Two, in contrast, offers detailed engagement with relevant empirical work. It exposes how, even setting aside the concerns identified in Part One, a dilemma confronts the believer in unconscious perception. This dilemma arises because ordinary perception is an individual-level state or occurrence, yet criteria sufficiently stringent to guarantee that a putatively perceptual state is unconscious vitiate the grounds for its attribution to the individual. The dilemma foments a hypothesis, namely that the conditions for genuine, individual-level perception are sufficient conditions for perceptual consciousness. The viability of this hypothesis should unnerve anyone who thinks unconscious perception is simply an empirical given. (shrink)

Intermodal representationalism is a popular theory of consciousness. This paper argues that intermodal representationalism is false, or at least likely so. The argument turns on two forms of exceptional episodic memory: hyperthymesia and prodigious visual memory in savant syndrome. Emerging from this argument is a broader lesson about the relationship between memory and perception; that it may be possible to entertain in memory the very same content as in a corresponding perceptual experience, and that the ‘overflow’ interpretation of the classic (...) Sperling paradigm experiments may not fully generalize. (shrink)

Do we perceptually experience moral properties like rightness and wrongness? For example, as in Gilbert Harman’s classic case, when we see a group of young hoodlums pour gasoline on a cat and ignite it, can we, in the same robust sense, see the action’s wrongness?. Many philosophers have recently discussed this question, argued for a positive answer and/or discussed its epistemological implications. This paper presents a new case for a negative answer by, first, getting much clearer on how such experience (...) could be possible at all; second, responding the only argument for a positive answer; and, finally, arguing that postulation of such experience is explanatorily redundant.

Väitetään, että nykypäivän populismi vetoaa tosiasioiden sijasta ”kokemukseen”. Mutta mitä on kokemus? Se ei ole vain ennakkoluuloihin nojautuvaa mutua eikä myöskään pelkkää empiirisen datan rekisteröintiä mutta liittyy molempiin. Artikkelin luoma tiivis katsaus kokemuksen käsitehistorian pääpiirteisiin osoittaa, että länsimaisen filosofian perinteessä kokemus on ymmärretty ohittamattomana vaiheena tiedon hankkimisessa ja koettelemisessa. Toisaalta kokemukseen on liitetty tiettyjä tiedollisia heikkouksia – kontingenssi, tilannesidonnaisuus ja ennakoimattomuus – jotka tieteellinen metodi on eri tavoin pyrkinyt voittamaan. Artikkeli esittää, että 1900-luvun filosofinen hermeneutiikka irrottautuu tästä perinteisestä kokemuksen välineellistämisestä (...) ja alistamisesta korkeammille päämäärille ja keskittyy uudella ja hedelmällisellä tavalla juuri mainittuihin kokemuksen ”vaaroihin”. Hermeneuttisesti ymmärretty kokemus muodostuu äärellisen ihmisen ainutkertaisista kohtaamisista todellisuuden muuttuvan ja ehtymättömän mielekkyyden kanssa – omalle ymmärrykselle vieraan toiseuden ja samalla oman ymmärryksen äärellisyyden ja inhimillisen äärellisyyden kohtaamisesta.

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

Thomas Reid offers an explanation of how memory of events is possible. This paper presents, criticize,s and amends his view that memory not only preserves our knowledge of the external world, but also contributes to such knowledge, by being essential for the perception of events. Reid’s views on memory are in line with his generalanti-skeptical commitments, and thus attractive, for several reasons. One reason is that, just like perception, memory is not infallible, but it can constitute or, at least, ground (...) knowledge. Reid argues that memory, like perception, is immediate: it gives direct access to the external world, and not to mental representations of the external world. Another reason is that Reid’s explanation of how memory of events works emphasizes the impor- tance of the divide between memory and perception and consciousness: it is one thing to perceive or be conscious of something; it is another to remember that thing. Despite these advantages, a careful study of Reid’s views on memory will uncover a serious problem of general philosophical interest: it is unclear how exactly we are able to remember events episodically, since it is not settled whether we ever literally perceive events. This problem is engendered by a clash of the following two intuitions: (i) we can perceive only presently existing things, and (ii) we can remember events, which usually span periods of time longer than the present (whether the present is durationless or not).

In the past two decades a number of arguments have been given in favor of the possibility of phenomenal consciousness without attentional access, otherwise known as phenomenal overflow. This paper will show that the empirical data commonly cited in support of this thesis is, at best, ambiguous between two equally plausible interpretations, one of which does not posit phenomenology beyond attention. Next, after citing evidence for the feature-integration theory of attention, this paper will give an account of the relationship between (...) consciousness and attention that accounts for both the empirical data and our phenomenological intuitions without positing phenomenal consciousness beyond attention. Having undercut the motivations for accepting phenomenal overflow along with having given reasons to think that phenomenal overflow does not occur, I end with the tentative conclusion that attention is a necessary condition for phenomenal consciousness. -/- .

Philosophers frequently comment on the intimate connection there is between something’s being present in perceptual experience and that thing’s being, or at least appearing to be, temporally present. Yet, there is relatively little existing work that goes beyond asserting such a connection and instead examines its specific nature. In this paper, I suggest that we can make progress on the latter by looking at two more specific debates that have hitherto been conducted largely isolation from each other: one about the (...) nature of conscious experience and one about the nature of time itself. The first concerns the extent to which the temporal properties of experience form an exception to the transparency of experience, meaning that introspection can provide support for one particular view of how experience itself is structured temporally; the second concerns the question as to whether there is something about experience that gives us grounds for thinking that the present is somehow metaphysically special. As I argue, the idea of a connection between experiential presence and temporal presence plays a key background role in each of these debates. Yet it can also, in each of them, be seen to draw one side towards making claims that are supposed to express an important truth but are at the same time, on the face of it, self-contradictory. In each case, resolving what it actually is that these claims are trying to get at turns on recognizing a distinctive feature of perceptual experience, which I refer to as its lack of temporal viewpointedness. Recognising this feature also helps in making sense of what the issues at stake actually are in the intuition of an intimate connection between experiential presence and temporal presence. (shrink)

In the literature on episodic memory, one claim that has been made by a number of psychologists, and that is also at least implicit in some of the accounts given by philosophers, is that being able to recollect particular past events in the distinctive way afforded by episodic memory requires the possession of aspects of a theory of mind, such as a grasp of the relationship between one’s present recollective experience and one’s own past perceptual experience of the remembered event. (...) In this paper, I re-examine what connection, if any, there is between episodic memory and theory of mind. I first criticize the dominant way in which this connection has been construed theoretically, which – perhaps influenced by other aspects of theory of mind research – has sought to link the possession of episodic memory primarily with a grasp of the idea of representation, or the idea of informational access. I then argue for a novel, alternative, way of connecting episodic memory and theory of mind, which focuses on the category of an experience, and on the role a grasp of that category might be seen to play in episodic recollection. In doing so, I also draw attention to a dimension of our understanding of the mental which remains as yet underexplored in the literature on theory of mind. (shrink)

This paper proposes a methodological strategy to investigate the question of the individuation of the senses both from a commonsensical and a scientific point of view. We start by discussing some traditional and recent criteria for distinguishing the senses and argue that none of them taken in isolation seems to be able to handle both points of views. We then pay close attention to the faculty of hearing which offers promising examples of the strategy we pursue of combining commonsense and (...) science. In particular, we argue in favour of a distinction between two kinds of modes of presentation associated with sound perception: a mechanical mode of presentation that makes sounds perceptible by other modalities than audition such as touch and a tonal mode of presentation that makes people conceive of sounds as the proper objects of auditory perception.

This article responds to two arguments against ‘Epistemic Perceptualism’, the view that emotional experiences, as involving a perception of value, can constitute reasons for evaluative belief. It first provides a basic account of emotional experience, and then introduces concepts relevant to the epistemology of emotional experience, such as the nature of a reason for belief, non-inferentiality, and prima facie vs. conclusive reasons, which allow for the clarification of Epistemic Perceptualism in terms of the Perceptual Justificatory View. It then challenges two (...) arguments which purport to show that emotional experience is not a source of reasons for evaluative belief. The first argument claims that because normative why-questions are always appropriate in the case of emotions, then emotions can never be conclusive reasons for corresponding evaluative beliefs. The second purports to show that appeal to emotional experience as a source of reasons for evaluative beliefs renders emotions problematically self-justifying, and since emotions cannot be self-justifying, they cannot provide any sort of reason for corresponding evaluative beliefs. This article responds to these arguments, and in doing so shows there is still much to be learned about the epistemology of emotional experience by drawing analogies with perceptual experience.

Phenomenal character is the what-it's-likeness of subjective experience. I develop an ontology of phenomenal feel as process. My being in some phenomenal state R is the process of my instantiating R’s neurological correlate. The ontology explains why we have asymmetric epistemic access to phenomenal characters: the ontological ground for the subjective or first-personal stance is different from the ontological ground for the objective or third-personal stance. I end by situating my account in debates about physicalism.

Thomas Reid's philosophy of mind, epistemology, and philosophy of language all rely on his account of signs and signification. On Reid's view, some entities play a role of indicating other entities to our minds. In some cases, our sensitivity to this indication is learned through experience, whereas in others, the sensitivity is built in to our natural constitutions. Unlike representation, which was presumed to depend on resemblances and necessary connections, signification is the sort of relationship that can occur without any (...) intrinsic ties between the sign and the thing signified. Of particular interest is the priority Reid gives to natural signs. Reid deploys his robust account of natural signs in a way that allows him to sidestep some skeptical worries common in the early modern period, as well as in grounding “artificial” human languages like English or Cantonese on a more basic human capacity for communication, that is, itself, the result of our sensitivity to natural signs of other people's minds.

Seeing aspects is a dominant theme in Wittgenstein's 1940s writings on philosophy of psychology. Interpreters disagree about what Wittgenstein was trying to do in these discussions. I argue that interpreting Wittgenstein's observations about the interrelations between “noticing an aspect” and other psychological concepts as a systematic theory of aspect‐seeing diminishes key lessons of Wittgenstein's explorations: these interrelations are enormously complicated and “noticing an aspect” resists neat classification. Further, Wittgenstein invites us to engage in his “placing activity,” and by doing so (...) we are building a skill that is valuable for enabling us to help ourselves when we encounter conceptual difficulties.

In this paper I will discuss the intentionalist view of perception, and present some arguments to support the view that, contrary to Michael Martin’s criticism, intentionalists do not need to conceive the content of perception as either singular or general, because this is not the way that it should be thought. The right way to conceive the representational content of perception is by considering it as informational and functional.

Recently, several theorists have proposed that we can perceive a range of high-level features, including natural kind features (e.g., being a lemur), artifactual features (e.g., being a mandolin), and the emotional features of others (e.g., being surprised). I clarify the claim that we perceive high-level features and suggest one overlooked reason this claim matters: it would dramatically expand the range of actions perception-based theories of action might explain. I then describe the influential phenomenal contrast method of arguing for high-level perception (...) and discuss some of the objections that have been raised against this strategy. Finally, I describe two emerging defenses of high-level perception, one of which appeals to a certain class of perceptual deficits and one of which appeals to adaptation effects. I sketch a challenge for the latter approach. (shrink)

Doxasticism about our awareness of normative (i.e. justifying) reasons – the view that we can recognise reasons for forming attitudes or performing actions only by means of normative judgements or beliefs – is incompatible with the following triad of claims: -/- (1) Being motivated (i.e. forming attitudes or performing actions for a motive) requires responding to and, hence, recognising a relevant reason. -/- (2) Infants are capable of being motivated. -/- (3) Infants are incapable of normative judgement or belief. -/- (...) It should be clear that (3) is true, given that infants lack the required reflective and conceptual capacities. So doxasticists have to reject either (1) or (2) (or both). But this forced choice may be understood as a dilemma for doxasticism. On the hand, doxasticists may adopt a Kantian approach and reject (2), precisely because they think that motivation presupposes the doxastic recognition of reasons, and because infants lack the capacity to doxastically recognise reasons. But this choice seems to wrongly reduce the responses of infants to mere reflexes or instinctive reactions. On the other hand, doxasticists may choose a Humean route and deny (1) by espousing a purely causal or teleological account of motivation. But this would mean detrimentally ignoring the normative nature of (some instances of) motivation. -/- One elegant way of avoiding this dilemma is to give up doxasticism and instead endorse experientialism – the view that we enjoy some experiential access to reasons, which is independent of, and perhaps more fundamental than, our capacity to form normative judgements and beliefs. In this talk, I would like to provide an argument for the existence of such a non-doxastic form of access to reasons. More specifically, I aim to defend the claim that our basic awareness of reasons is phenomenal in nature. What this means is that it forms part of our access from the inside to those of our mental episodes that provide us with access to reasons. In other words, when we introspectively attend to reason-giving mental episodes and what they are about, we have the impression of the presence of a reason for us. My defence of this experientialist alternative to doxasticism will primarily focus on perceptual reasons for first-order beliefs about the external world. (shrink)

Beauty and the End of Art shows how a resurgence of interest in beauty and a sense of ending in Western art are challenging us to rethink art, beauty and their relationship. By arguing that Wittgenstein's later work and contemporary theory of perception offer just what we need for a unified approach to art and beauty, Sonia Sedivy provides new answers to these contemporary challenges. These new accounts also provide support for the Wittgensteinian realism and theory of perception that make (...) them possible. -/- Wittgenstein's subtle form of realism explains artworks in terms of norm governed practices that have their own varied constitutive norms and values. Wittgensteinian realism also suggests that diverse beauties become available and compelling in different cultural eras and bring a shared 'higher-order' value into view. With this framework in place, Sedivy argues that perception is a form of engagement with the world that draws on our conceptual capacities. This approach explains how perceptual experience and the perceptible presence of the world are of value, helping to account for the diversity of beauties that are available in different historical contexts and why the many faces of beauty allow us to experience the value of the world's perceptible presence. -/- Carefully examining contemporary debates about art, aesthetics and perception, Beauty and the End of Art presents an original approach. Insights from such diverse thinkers as Immanuel Kant, Hans-Georg Gadamer and Arthur Danto, Alexander Nehamas, Elaine Scarry and Dave Hickey are woven together to reveal how they make good sense if we bring contemporary theory of perception and Wittgensteinian realism into the conversation.

This paper argues that perception is a mode of engagement with individuals and their determinate properties. Perceptual content involves determinate properties in a way that relies on our conceptual capacities no less than on the properties. The “richness” of perceptual experience is explained as a distinctive individual and property involving content. This position is developed in three steps: (i) novel phenomenological description of lived experience; (ii) detailed reconstruction of Gareth Evans’ proposal that we are capable of genuinely singular thought that (...) involves individuals under modes of presentation; (iii) re-consideration of the re-identification condition on conceptual contents.

In this paper I argue that a necessary condition of one’s perceiving God is that an experience of the right phenomenological sort be caused in one ‘directly enough’ by God and - bypassing the issue of what is necessary for an experience to be of the right phenomenological sort - discuss some difficulties in finding reasons for thinking that God has or has not ‘directly enough’ caused any such experience.

The paper deals with the controversy between internalism and externalism on the nature of mental states, and its relevance to the philosophy of perception. In particular, the controversy between Hilary Putnam's natural realism and John Searle's direct realism is discussed. It is argued that Searle's defense of internalism fails to meet Putnam’s objections. Putnam’s case is even strengthened and the very source of the internalism vs. externalism controversy is identified in their shared assumptions. The rejection of these assumptions, together with (...) the underlying myth of Cartesian Theater, makes the controversy meaningless. Finally, the relations of Searle’s and Putnam’s views to the Cartesian framework in the philosophy of perception are discussed. (shrink)

The philosophical issues raised by perception make it one of the central topics in the philosophical tradition. Debate about the nature of perceptual knowledge and the objects of perception comprises a thread that runs through the history of philosophy. In some historical periods the major issues have been predominantly epistemological and related to scepticism, but an adequate understanding of perception is important more widely, especially for metaphysics and the philosophy of mind. For this reason Barry Maund provides an account of (...) the major issues in the philosophy of perception that highlights the importance of a good theory of perception in a range of philosophical fields, while also seeking to be sensitive to the historical dimension of the subject. The work presents chapters on forms of natural realism; theories of perceptual experience; representationalism; the argument from illusion; phenomenological senses; types of perceptual content; the representationalist/intentionalist thesis; and adverbialist accounts of perceptual experience. The ideas of, among others, Austin, Dretske, Heidegger, Millikan, Putnam and Robinson are considered and the reader is given a philosophical framework within which to consider the issues. (shrink)

HOW MUCH DO WE LEARN ABOUT HALLUCINATIONS FROM THOUGHT-EXPERIMENTS? The idea that our sensory experience cannot serve as a ground for knowledge lingers on within philosophical thinking from its very beginning. Since even the ancient sceptics argued against the possibility of knowledge based on sense perception due to its potentially illusory or hallucinatory character, it seems reasonable to address the issue of hallucination itself. The purpose of this paper is to discuss upon the philosophical account of hallucination present in current (...) debates. I will mainly work on the so-called ‘argument from hallucination’ which provides a prevalent objection both against the direct realism theory of perception, and externalist theories of content of experience. My primary intention will be to single out the ontological claims concerning hallucinatory experience that constitute the core of the argument from hallucination. Moreover, the legitimacy of philosophical theses concerning hallucination will be discussed both by means of philosophical analysis, and in the light of chosen empirical findings. (shrink)

How does attention contribute to perceptual experience? Within cognitive science, attention is known to contribute to the organization of sensory features into perceptual objects, or “object-based organization.” The current paper tackles a different type of organization and thus suggests a different role for attention in conscious perception. Within every perceptual experience we find that more subjectively interesting percepts stand out in the foreground, whereas less subjectively interesting percepts are relegated to the background. The sight of a sycamore often gains the (...) visual foreground for a nature lover, whereas the sound of a violin often gains the auditory foreground for a music lover, but not necessarily vice versa. How does the perceptual system organize early sensory processing according to the subject’s interests? The current paper reveals how this subject-based organization is brought about and maintained through top-down attention. In fact, the current paper argues that top-down attention is necessary for conscious perception in so far as it is necessary for bringing about and maintaining the subject-based organization of perceptual experience.

In this paper, I discuss Noë’s enactive account of our perceptual encounter with the intrinsic properties of the surrounding objects. First, I argue that this view falls into a dilemma in which either we are left without a satisfactory explanation of this encounter or, in order to keep Noë’s view, we must abandon our ordinary intuitions about the ontological status of the intrinsic properties of objects. Then, I show that, strikingly, there is a suggestive unofficial strand running in Noë that (...) avoids this dilemma. Finally, I argue this unofficial thread leads to a view about the perspectival character of perceptual experience and the place of sensorimotor understanding in perceptual content that is to be preferred over Noë’s official view about these issues.

The philosophy of perception has been mostly focused on vision, to the detriment of other modalities like audition or olfaction. In this paper I focus on olfaction and olfactory experience, and raise the following questions: is olfaction a perceptual-representational modality? If so, what does it represent? My goal in the paper is, firstly, to provide an affirmative answer to the first question, and secondly, to argue that olfaction represents odors in the form of olfactory objects, to which olfactory qualities are (...) attributed. In order to do this I develop an empirically adequate notion of olfactory object that is sensitive to the peculiarities of olfaction, and defend it against various objections. (shrink)

This dissertation is concerned with three related problems about the nature of perception: Of what are we immediately aware in perceptual experience? Of what are we immediately aware when we introspect our experiences? How should we understand the role of perception in an account of basic empirical knowledge? ;It is argued that the immediate objects of perceptual experience are external material objects, and that the only way to defend such a direct realist view is by endorsing a form of the (...) disjunctive conception of experience---the view that perceptual and hallucinatory experiences are of fundamentally different kinds, requiring different analyses. Several recent attempts at developing non-disjunctive versions of direct realism are shown face a dilemma: they either fail to be forms of direct realism, or they turn out to be versions of disjunctivism. ;In the second chapter, it is argued that there are features of one's own experiences of which one can be aware in introspection. On the basis of cases of synaesthesia, a condition marked by cross-modal sensory experiences, it is argued that two experiences can have the same representational content but different phenomenal characters. Since the phenomenal character of synaesthetic experiences is only accessible to introspection, it is argued that these cases are compatible with direct realism. ;In the third chapter, it is argued that knowledge should require strict rather than lax standards, Problems for such strict-standards views, concerning higher-level knowledge of the epistemic status of one's first-order beliefs, and the closure of knowledge under known implication, are addressed. Out of these considerations a tension emerges between the externalist element in the direct realist account of perception and recently influential contextualist treatments of knowledge. It is argued that the best resolution is to provide distinct accounts of perceptual and reflective knowledge. (shrink)
