Human beings have the ability to ‘augment’ reality by superimposing mental imagery on the visually perceived scene. For example, when deciding how to arrange furniture in a new home, one might project the image of an armchair into an empty corner or the image of a painting onto a wall. The experience of noticing a constellation in the sky at night is also perceptual-imaginative amalgam: it involves both seeing the stars in the constellation and imagining the lines that connect them (...) at the same time. I here refer to such hybrid experiences – involving both a bottom-up, externally generated component and a top-down, internally generated component – as make-perceive (Briscoe 2008, 2011). My discussion in this paper has two parts. In the first part, I show that make-perceive enables human beings to solve certain problems and pursue certain projects more effectively than bottom-up perceiving or top-down visualization alone. To this end, the skillful use of projected mental imagery is surveyed in a variety of contexts, including action planning, the interpretation of static mechanical diagrams, and non-instrumental navigation. In the second part, I address the question of whether make-perceive may help to account for the “phenomenal presence” of occluded or otherwise hidden features of perceived objects. I argue that phenomenal presence is not well explained by the hypothesis that hidden features are represented using projected mental images. In defending this position, I point to important phenomenological and functional differences between the way hidden object features are represented respectively in mental imagery and amodal completion.

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)

The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same (...) theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative. (shrink)

Mental Imagery, whereby we experience aspect of a perceptual scene or perceptual object in the absence of direct sensory stimulation is ubiquitous. Often the existence of mental imagery is demonstrated by asking one’s reader to volitionally generate a visual object, such as closing ones eyes and imagining an apple. However, mental imagery also arises in auditory, tactile, interoceptive, and olfactory cases. A number of influential philosophical theories have attempted to explain mental imagery in terms of belief-based forms of representation using (...) the Dependence Thesis, dependence upon means of access, such as enactivism, or in terms of the similarity of content with perceptual processing. The focus of this paper concerns the later approach and in particular assessing if Nanay’s promissory note that his theory is applicable to modalities other than vision, such as smell, seems likely to be of theoretical tender. The thesis argued for in this paper is that olfactory imagery exists and is best accounted for by considering it as a type of perceptual processing with a unique representational format relative to the olfactory perceptual modality. The paper concludes by summarizing the applicability of Nanay’s theory of mental imagery for olfaction and suggests some further issues that arise when transitioning to multi-modal mental imagery.

Perception plays a central and wide-ranging role in the philosophy of Margaret Cavendish. In this paper, I argue that Cavendish holds a naïve realist theory of perception. The case draws on what Cavendish has to say about perceptual presentation, the role of sympathy in experience, the natures of hallucination and of illusion, and the individuation of kinds. While Cavendish takes perception to have representational content, I explain how this is consistent with naïve realism. In closing, I address challenges to the (...) interpretation, one of which turns on whether Cavendish allows for action at a distance. I argue that she does. (shrink)

How do we know about other minds on the basis of perception? The two most common answers to this question are that we literally perceive others’ mental states, or that we infer their mental states on the basis of perceiving something else. In this paper, I argue for a different answer. On my view, we don’t perceive mental states, and yet perceptual experiences often immediately justify mental state attributions. In a slogan: other minds are neither seen nor inferred. I argue (...) that this view offers the best explanation of our deeply equivocal intuitions about perception-based mental state attributions, and also holds substantial interest for the epistemology of perception more generally.

According to a variety of recent ‘enactivist’ proposals, the material basis of conscious experience might extend beyond the boundaries of the brain and nervous system and into the environment. Clark (2009) surveys several such arguments and finds them wanting. Here I respond on behalf of the enactivist. Clarifying the commitments of enactivism at the personal and subpersonal levels and considering how those levels relate lets us see where Clark’s analysis of enactivism goes wrong. Clark understands the enactivists as attempting to (...) provide hypotheses about the subpersonal mechanisms underlying experience according to which those mechanisms contingently include portions of the environment. But understanding enactivism instead as involving a relational conception of experience at the personal level, with apparent implications for the location of the subpersonal mechanisms of experience, allows us to make better sense of the enactivist arguments, and make the case for conscious externalism.

The transparency of perceptual experience has been invoked in support of many views about perception. I argue that it supports a form of enactivism—the view that capacities for perceptual experience and for intentional agency are essentially interdependent. I clarify the perceptual phenomenon at issue, and argue that enactivists should expect to find a parallel instance of transparency in our agentive experience, and that the two forms of transparency are constitutively interdependent. I then argue that i) we do indeed find such (...) parallels: the way in which an action is directed towards its goal through our bodily movements parallels the way in which an experience is directed towards its object through our perceptual sensation, and ii) reflecting on sensorimotor skills shows why the two instances of transparency are constitutively interdependent. Section 4 gives reasons for generalizing beyond the cases considered so far by applying the enactive view to Kohler's landmark studies of perceptual adaptation. The final section clarifies the form of enactivism to which the previous sections point. The view that emerges is one whereby our perceptual and practical skills are interrelated aspects of a single capacity to have one's mind intentionally directed upon the world. The transparency of experience, on this view, is achieved in virtue of our capacities as agents as much as it is given in virtue of our capacities as perceivers. (shrink)

Whether perceptual experience represents high-level properties like causation and natural-kind in virtue of its phenomenology is an open question in philosophy of mind. While the question of high-level properties has sparked disagreement, there is widespread agreement that the sensory phenomenology of perceptual experience presents us with low-level properties like shape and color. This paper argues that the relationship between the sensory character of experience and the low-level properties represented therein is more complex than most assume. Careful consideration of mundane examples, (...) like looking at a coin from an oblique angle, show that the low-level properties represented in experience do not necessarily figure in the sensory character of the experience. Furthermore, the sensible properties invoked when characterizing the sensory character of a perceptual experience are not necessarily included in the sensible properties represented in a perceptual experience. On this basis it is argued that perceptual experience has a disunified metaphysics, consisting in distinct sensory and cognitive components. The account is developed in relation to existing unified and disunified accounts, and discussed in terms of its implications for cognitive penetration, the reliability of introspection, the transparency of experience, and cognitive phenomenology.

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.

In the last years, we have attended to different attempts to extend the notion of affordance to include mental or cognitive actions. In short, the idea is that our capacity to perform some cognitive functions such as counting, imagining, mathematical reasoning, and so on, is preceded by our awareness of cognitive or mental affordances. In this paper, we analyze two of these attempts, Mental Affordance Hypothesis, and cognitive horizons, and conclude that they fail to deliver their promise. Our argument is (...) two-fold. First, we show that both proposals lack an explanation for how these affordances can be perceived or experienced by the individuals. Second, we argue, focusing on the examples provided by the authors, that the introduction of cognitive affordances is not justified on explanatory grounds. In other words, neither of these proposals offers a compelling justification for thinking that performing said “mental acts” requires the perception of mental or cognitive affordances. Hence, the existence of mental or cognitive affordances remains both scientifically mysterious and explanatorily unjustified. (shrink)

Ordinary human perceivers know that visual objects are perceivable from standpoints other than their own. The aim of this paper is to provide an explanation of how perceptual experience equips perceivers with this knowledge. I approach the task by discussing a variety of action-based theories of perception. Some of these theories maintain that standpoint transcendence is required for shape perception. I argue that this standpoint transcendence must take place in the phenomenal present and that it can be explained in terms (...) of the experience of perceivers who jointly attend to an object. Joint perceivers experience objects as being perceived from standpoints other than their own. They operate in what I call “social space”, in which they single out objects by triangulating targets’ locations relative to their co-perceivers’ standpoints on these targets. It is then possible to explain the public character of the objects of individual experience by appeal to what I call “public space”. This is a spatial framework whose locations are presented as standpoints whence joint attention to the target would ensue, were they occupied by co-perceivers. If shape perception requires standpoint transcendence, then shape perceivers operate in public space and are thus capable of singling out targets by triangulating their locations from standpoints other than their own. If it doesn’t, then the introduction of a public spatial framework is an additional step whose introduction explains how perceivers come to experience objects as perceivable from standpoints other than their own.

According to the Self-Location Thesis, one’s own location can be among the things that visual experience represents, even when one’s body is entirely out of view. By contrast, the Minimal View denies this, and says that visual experience represents things only as "to the right", etc., and never as "to the right of me". But the Minimal View is phenomenologically inadequate: it cannot explain the difference between a visual experience of self-motion and one of an oppositely moving world. To show (...) this, I argue (i) that these experiences are different in an important respect, (ii) that this difference is genuinely experiential, (iii) that it is visual, (iv) that it is not purely phenomenal, and (v) that it cannot be identified with anything other than the apparent motion of the self. So the Self-Location Thesis is upheld: reports of one’s own motion can correspond to aspects of visual experiences every bit as basic to their contents as the apparent motion or rest of the things one has in view. (shrink)

I offer an explanation of how subjects are able to perceive the intrinsic spatial properties of objects, given that subjects always perceive from a particular location. The argument proceeds in two steps. First, I argue that a conception of space is necessary to perceive the intrinsic spatial properties of objects. This conception of space is spelled out by showing that perceiving intrinsic properties requires perceiving objects as the kind of things that are perceivable from other locations. Second, I show that (...) having such a conception of space presupposes that a subject represent her location in relation to perceived objects. More precisely the thesis is that a subject represents her location as the location from which she both perceives objects and would act in relation to objects were she to act. So I argue that perception depends on the capacity to know what it would be to act in relation to objects. (shrink)

The unity of consciousness has so far been studied only as a relation holding among the many experiences of a single subject. I investigate whether this relation could hold between the experiences of distinct subjects, considering three major arguments against the possibility of such ‘between-subjects unity’. The first argument, based on the popular idea that unity implies subsumption by a composite experience, can be deflected by allowing for limited forms of ‘experience-sharing’, in which the same token experience belongs to more (...) than one subject. The second argument, based on the phenomenological claim that unified experiences have interdependent phenomenal characters, I show to rest on an equivocation. Finally, the third argument accuses between-subjects unity of being unimaginable, or more broadly a formal possibility corresponding to nothing we can make sense of. I argue that the familiar experience of perceptual co-presentation gives us an adequate phenomenological grasp on what between-subjects unity might be like. (shrink)

The psychology and phenomenology of our knowledge of other minds is not well captured either by describing it simply as perception, nor by describing it simply as inference. A better description, I argue, is that our knowledge of other minds involves both through ‘perceptual co-presentation’, in which we experience objects as having aspects that are not revealed. This allows us to say that we perceive other minds, but perceive them as private, i.e. imperceptible, just as we routinely perceive aspects of (...) physical objects as unperceived. I discuss existing versions of this idea, particularly Joel Smith’s, on which it is taken to imply that our knowledge of other minds is, in these cases, perceptual and not inferential. Against this, I argue that perceptual co-presentation in general, and mind-perception in particular, yields knowledge that is simultaneously both perceptual and inferential. (shrink)

Sensorimotor theories understand perception to be a process of active, exploratory engagement with the environment, mediated by the possession and exercise of a certain body of knowledge concerning sensorimotor dependencies. This paper aims to characterise that exercise, and to show that it places constraints upon the content of sensorimotor knowledge itself. Sensorimotor mastery is exercised when it is put to use in the service of intentional action-planning and selection, and this rules out certain standard readings of sensorimotor contingency knowledge. Rather (...) than holding between movements and sensory inputs or appearances, sensorimotor contingencies concern the suite of ways in which an object can be revealed through exploration. Sensorimotor knowledge is thus directed through experience to the world itself. (shrink)

Abstract The paper considers the success of enactive realism about perception; the theory that perceivers gain direct access to the mind-independent physical world through their exercise of sensorimotor skills and understanding. I argue that while it is plausible that the possession of some forms of knowledge, conceptual or practical, may enable perceptual contact with the environment, the role of sensorimotor mastery is not as pervasive as the enactive realist proposes. Non-veridical perception, furthermore, cannot be captured adequately by enactivist resources under (...) a disjunctivist framework. (shrink)

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology. (shrink)

In this essay we will argue for the following theses: 1- know-how is not a form of practical knowledge devoid of propositional sense; 2- the relationship between each perception and the body itself is metaphysically contingent. 3- it is up to the brain to configure or to shape a physical body (Körper) into a living body (Leib) and not the other way around; 4- phenomenal externalism of enactivist nature, even in its mild form, is empirically implausible: the correlation between the (...) conscious character of sensory experience with spatiotemporal neuronal patterns is much more systematic and regular than with anything outside the brain. But in its radical form is entirely implausible and contra-intuitive: phenomenal duplicates are not necessarily duplicates of agency; in short, 5-we are our own brain that has a body, avatars, and artifacts, properly configured and molded by the brain, and not a body that has a brain among other essential organs.

According to ‘direct social perception’ (DSP) accounts of social cognition, perception may be ‘smart’ enough on its own to inform us about other people’s emotions. Some DSP advocates suggest that ‘smart’ social perception should be conceived along ‘enactive’ lines. In this paper, I suggest that DSP needs social perception to have representational content. This seems in tension with the main versions of enactivism, which deny that perception is representational. I thus present the following challenge to ‘enactive’ versions of DSP: either (...) they show how perception can have the requisite smartness without representational content, which I doubt that they can, or they embrace the orthodox idea that perceptual experiences have representational contents. I also suggest that DSP defenders, whether or not they want to be enactivists, can cheerfully accept the latter idea. (shrink)

Sounds are audible, and sound sources are audible. What is the audible relation between audible sounds and audible sources? Common talk and philosophy suggest three candidates. The first is that sounds audibly are properties instantiated by their sources. I argue that sounds are audible individuals and thus are not audibly instantiated by audible sources. The second is that sounds audibly are effects of their sources. I argue that auditory experience presents no compelling evidence that sounds audibly are causally related to (...) audible sources. The third is that sounds audibly are related mereologically to their sources. I present and offer a defence of this third candidate. (shrink)

In this short essay I respond to the criticism of Action in Perception (2004) advanced by Ryan Hickerson and Fred Keijzer. In particular, I provide a brief precis of the main argument of Action in Perception. I seek to clarify the claims made in the book about the relation between perception and action, the importance of sensorimotor knowledge. I discuss the problem of "sensorimotor chauvinism," that of the "ping-pong playing robot," and the problem of perceptual presence.

In the “Notes for Lectures on “Private Experience‘ and “Sense Data‘", Wittgenstein endorsed one kind of inverted spectrum hypothesis and rejected another. This paper argues that the kind of inverted spectrum hypothesis that Wittgenstein endorsed is the thin end of the wedge that precludes a Wittgensteinian critique of the kind of inverted spectrum hypothesis he rejected. I will attempt to explicate the difference between the innocuous and dangerous scenarios, to give arguments in favor of the coherence of the dangerous scenario, (...) and to show that the standard arguments to the effect that the dangerous scenario is impossible are flawed or ineffective against the version of the dangerous scenario whose coherence I will be advocating. I will also agree with what I think is Wittgenstein’s position that the kind of inverted spectrum hypothesis he rejected lets qualia in the door, where qualia are qualities of experiential states whose phenomenal character cannot be expressed in natural language. Further, I will argue that acknowledging the coherence of the innocuous inverted spectrum commits Wittgenstein to the coherence of the dangerous inverted spectrum, thereby undermining Wittgenstein’s deepest views about the mind. In other work, I have used the inverted spectrum hypothesis as an argument against functionalism and representationism, but here the focus is on its role in arguing for the possibility of qualia.

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to which we (...) represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

Amodal completion is usually characterized as the representation of those parts of the perceived object that we get no sensory stimulation from. In the case of the visual sense modality, for example, amodal completion is the representation of occluded parts of objects we see. I argue that relationalism about perception, the view that perceptual experience is constituted by the relation to the perceived object, cannot give a coherent account of amodal completion. The relationalist has two options: construe the perceptual relation (...) as the relation to the entire perceived object or as the relation to the unoccluded parts of the perceived object. I argue that neither of these options are viable. (shrink)

While nobody will ever know what it may be like to be God, there is a more basic question one may try to answer: does God have phenomenal consciousness, does He have experiences within a conscious point of view (POV)? Drawing on recent debates within philosophy of mind, I argue that He doesn’t: if God exists, ‘He’ is not phenomenally conscious, at least in the sense that there is no ‘divine subjectivity’. The article aims at displaying an incompatibility between God’s (...) being truly omnipresent on the one hand, and God’s having a genuine conscious POV on the other. This is shown by introducing the concept of ‘experiential location’ to clarify what shall be meant by ‘conscious POV’, then by exposing an inconsistency in the traditional concept of omnipresence, and finally by arguing that a consistent though weaker understanding of omnipresence is incompatible with God’s having a conscious POV. This paves the way for a ‘processual’ or computational conception of God, which may have its own metaphysical benefit. (shrink)

Our successful engagement with the world is plausibly underwritten by our sensitivity to affordances in our immediate environment. The considerable literature on affordances focuses almost exclusively on affordances for bodily actions such as gripping, walking or eating. I propose that we are also sensitive to affordances for mental actions such as attending, imagining and counting. My case for this ‘Mental Affordance Hypothesis’ is motivated by a series of examples in which our sensitivity to mental affordances mirrors our sensitivity to bodily (...) affordances. Specifically, subjects perceive opportunities to perform a mental action and their doing so leads, under the right conditions, to the automatic preparation of that action. I conclude by sketching a mental affordance research program that would reinforce my case for the Mental Affordance Hypothesis and establish its ramifications for a number of debates across philosophy and psychology.

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

In his book Action in Perception, Alva Noë poses what he refers to as the “problem of perceptual presence” and develops his enactive view as solution to the problem. Noë describes the problem of perceptual presence as the problem of how to conceive of the presence of that which, “strictly speaking,” we do not perceive. I argue that the “problem of perceptual presence” is ambiguous between two problems that need to be addressed by invoking very different resources. On the one (...) hand, there is the problem of how to conceive of the presence of objects as wholes, front side and back, and their constant properties. On the other hand, there is the problem of how to account for the presence of unattended detail. I focus on the first problem, which Noë approaches by invoking Husserlian ideas. I argue that Noë’s enactive view encounters difficulties, which can be dealt with by complementing it with Edmund Husserl’s idea of fulfillment and generally restoring the view to its original Husserlian context. Contrary to Noë’s purport, this involves regarding the view not as a theory of perception and perceptual content but as part of a descriptive–clarificatory project of conceptual analysis. The Husserlian phenomenologist analyzes, e.g., the concept of shape or color by investigating the fulfillment conditions pertinent to shape or color. In general, my critique of Noë’s enactive view serves to caution philosophers against unprincipled uses of Husserlian ideas. (shrink)

In her paper, ‘Action and Self-location in Perception’, Susanna Schellenberg argues that perceptual experience of an object's intrinsic spatial properties, such as its size and shape, requires a capacity to act. More specifically, Schellenberg argues that, to have a perceptual experience of an object's intrinsic spatial properties, a subject needs to have a certain practical conception of space, or a spatial know-how. That, in turn, requires self-locating representations, which locate the subject, relative to the perceptual object, as a perceiver and (...) an agent, viz., someone who has a capacity for actions. She also makes two objections, viz., the unification objection and the sentient statue objection, to Alva Noë's sensorimotor view, a different account of how perceptual experience depends on actions. I will argue that her objections jointly render problematic not only Noë's but also her own view. (shrink)

Disputes about what is phenomenologically manifest in conscious experience have a way of leading to deadlocks with remarkable immediacy. Disputants reach the foot-stomping stage of the dialectic more or less right after declaring their discordant views. It is this fact, I believe, that leads some to heterophenomenology and the like attempts to found Consciousness Studies on purely third-person grounds. In this paper, I explore the other possible reaction to this fact, namely, the articulation of methods for addressing phenomenological disputes. I (...) suggest two viable methods, of complementary value, which I call “the method of contrast” and “the method of knowability.”. (shrink)

The enactive approach to perception describes experience as a temporally extended activity of skillful engagement with the environment. This paper pursues this view and focuses on prosopagnosia both for the light that the theory can throw on the phenomenon, and for the critical light the phenomenon can throw on the theory. I argue that the enactive theory is insufficient to characterize the unique nature of experience specific to prosopagnosic subjects. There is a distinct difference in the overall process of detection (...) (with respect to eye movement sequence) of familiar and unfamiliar faces in prosopagnosia; in contrast, normal subjects use the same scanning strategy when exploring both kinds of faces despite an obvious difference in qualitative character. In light of this limitation I outline a supplemental view basing sensorimotor contingencies upon the establishment and reaffirmation of regularities within the organism as it engages with the environment. (shrink)

This paper develops an appearance view of perception (focusing on vision). When we see an object, we see it by having it appear some way to us. We see the object, not the appearance; but we see the object via the appearance. The appearance is subjectively conditioned: aspects of it depend on attributes of the subject. We mentally have the appearance and can reflect on it as an appearance. But in the primary instance, of veridical perception, it is the object (...) that we focus on and experience. I contrast this view with naive realism (sometimes called disjunctivism) (Brewer, Campbell, Noe) and with intentionalist or representationalist views, which I call the physical content view (Dretske, Tye, Crane, Hill, Burge). I agree with these views in rejecting sense-data intermediaries and in affirming direct perception, but I argue that direct perception occurs via appearances, making mine a critical direct realism. The other views attempt to explain the spatial content of perception (shape, size, distance) entirely through the physical properties of objects and their physical relation to the perceiver (viewing position). I argue instead that there are ineliminably subjective aspects of normal spatial perception, which are systematically manifested as a lack of full phenomenal constancy. This systematic underconstancy can’t be accounted for at all by a consistent naive realism; for the physical content view, it requires that most of our ordinary perception is classified as illusory, violating the spirit of that view. Accepting phenomenal underconstancy as pervasive, I suggest that our ability to perceive the mind-independent properties of objects depends on developed conceptual abilities. In the final section, I compare my appearance view with the adverbialism of Chisholm and the critical direct realism of Roy Wood Sellars. (shrink)

Seeking to avoid the typical binary choices between symbolic representations and no representations, or between functionally decomposable psychological processes and no psychological processes, or between direct perception of mind-independent physical properties and indirect perception of sense data, this article proposes that even a clear-thinking friend of Gibson can accept that perception of the environment is mediated by appearances and that such appearances are produced by functionally decomposable, rule-instantiating psychological processes. In so doing, it avoids both hyper-intellectualization of the perceptual process (...) and the positing of sense data as immediate objects of perception. It considers notions of perceptual mediation from classical Gestalt psychology, while referencing recent phenomenological arguments showing that perception does not simply conform to mind-independent physical properties. Perception presents objects and scenes under a phenomenal aspect, in a manner suitable to be action-guiding. Finally, it examines neuroscientific decompositions of Gibsonian information pickup mechanisms, finding that such mechanisms are reasonably described as effecting processes of construction. As a separate point, such mechanisms are usefully described as including subpersonal, non-symbolic representations and processes of information integration. (shrink)

Berkeley holds that objects in the world are constituted of ideas. Some commentators argue that for Berkeley, ideas are identical to acts of perception; this is taken to proceed from his view that ideas are like pains. In this paper, I evaluate the identity claim. I argue that although it does not follow from the pain analogy, nonetheless the texts suggest that Berkeley does think ideas and acts are identical. I show how Berkeley can account for objects persisting over time (...) and being perceivable by multiple observers, even if the ideas that constitute them are intermittent and dependent on particular actors.

This article reviews the enactive approach to perception, which defends the role of objects, the subject and the environment in the configuration of the phenomenal character of perception, that is, the qualitative dimension of experience. Initially the case of hallucination and its implications in the understanding of the phenomenal character of perception is retaken. Then, two positions within analytic philosophy of perception, representationalism and disjunctivism, are critically explored. Finally, enactivism is presented as a more promising alternative.

In this book the editors invited prominent researchers with different perspectives and deep insights into the various facets of the relationship between reality and representation in the following three classes of agent: in humans, in other living beings, and in machines. -/- The book enriches our views on representation and deepens our understanding of its different aspects, a question that connects philosophy, computer science, logic, anthropology, psychology, sociology, neuroscience, linguistics, information and communication science, systems theory and engineering, computability, cybernetics, synthetic (...) biology, and bioinformatics biosemiotics. This book will be relevant to researchers in these fields. (shrink)

Sensorimotor expectations concern how visual experience covaries with bodily movement. Sensorimotor theorists argue from such expectations to the conclusion that the phenomenology of vision is constitutively embodied: objects within the visual field are experienced as 3-D because sensorimotor expectations partially constitute our experience of such objects. Critics argue that there are two ways to block the above inference: to explain how we visually experience objects as 3-D, one may appeal to such non-bodily factors as expectations about movements of objects, not (...) the perceiver, or to the role of mental imagery in visual experience. But instead of using sensorimotor expectations to explain how objects are experienced within the visual field, we can instead use them to explain our experience of the visual field itself and, in particular, our experience of its limits; that is, our ever-present visual sense of there being more to see, beyond what’s currently within the visual field. Crucially, this inference from sensorimotor expectations to the constitutive embodiment of visual phenomenology is not threatened by the above two challenges. I thus present here a sensorimotor theory of the phenomenology of the visual field, that is, our experience of our visual fields as such. (shrink)

A central debate in contemporary philosophy of perception is between those who hold that perception is a detection relation of sensory awareness and those who hold that it is representational state akin to belief. Another key debate is between those who claim that we can perceive natural or artifactual kind properties, e.g. ‘being a tomato’, ‘being a doorknob’, etc. and those who hold we cannot. The current consensus is that these debates are entirely unrelated. I argue that this consensus is (...) wrong: the perception of natural or artifactal kinds favours representationalism. Naïve realists who wish to accommodate such perception should embrace a disunified metaphysics of perception, one that combines relational and representational events; call such a view ‘impure relationalism.’.

The problem of amodal perception is the problem of how we represent features of perceived objects that are occluded or otherwise hidden from us. Bence Nanay (2010) has recently proposed that we amodally perceive an object's occluded features by imaginatively projecting them into the relevant regions of visual egocentric space. In this paper, I argue that amodal perception is not a single, unitary capacity. Drawing appropriate distinctions reveals amodal perception to be characterized not only by mental imagery, as Nanay suggests, (...) but also by genuinely visual representations as well as beliefs. I conclude with some brief remarks on the role of object-directed bodily action in conferring a sense of unseen presence on an object's occluded features. (shrink)

A number of philosophers have held that we visually experience objects’ occluded parts, such as the out-of-view exterior of a voluminous, opaque object. That idea is supposed to be what best explains the fact that we see objects as whole or complete despite having only a part of them in view at any given moment. Yet, the claim doesn’t express a phenomenological datum and the reasons for thinking we do experience objects’ occluded parts, I argue, aren’t compelling. Additionally, I anticipate (...) and reply to attempts to salvage the idea by appeal to perceptual expectation and amodal completion. Lastly, I address potential concerns that the only way to capture the phenomenal character of perceiving voluminous objects is to say experience outstrips what’s in view, providing a description of such experience without any implication of that idea.

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)

The idea of representation has been central in discussions of intentionality for many years. But only more recently has it begun playing a wider role in the philosophy of mind, particularly in theories of consciousness. Indeed, there are now multiple representational theories of consciousness, corresponding to different uses of the term "conscious," each attempting to explain the corresponding phenomenon in terms of representation. More cautiously, each theory attempts to explain its target phenomenon in terms of _intentionality_, and assumes that intentionality (...) is representation. (shrink)

In their excellent book The Phenomenological Mind Shaun Gallagher and Dan Zahavi demonstrate that analytic philosophy of mind and cognitive science have much to learn from work conducted in the phenomenological tradition. In particular, they show how discussions about embodied cognition, about the self, and about mind-reading could be greatly enhanced if the lessons of phenomenology were heeded to. However, their discussion of the structure of intentionality is, in my view, less successful in this regard.

What is the relationship between sounds and time? More specifically, is there something essentially or distinctively temporal about sounds that distinguishes them from, say, colors, shapes, odors, tastes, or other sensible qualities? And just what might this distinctive relation to time consist in? Apart from their independent interest, these issues have a number of important philosophical repercussions. First, if sounds are temporal in a way that other sensible qualities are not, then this would mean that standard lists of paradigm secondary (...) qualities offered by Locke, Galileo, and other modern philosophers — lists which include colors, odors and sounds without any significant distinctions — overlook significant metaphysical differences. This, in turn, would threaten to undermine the coherence of the modern understanding of secondary qualities itself. Moreover, a number of authors have recently urged that the essential temporality of sounds makes it impossible to understand sounds as properties (except on a trope theory of properties; see note 3). If true, and given the more or less universal view that colors are properties, this last conclusion would make potentially inapplicable to sounds much of the comparatively well-developed philosophical taxonomy and apparatus that has arisen in philosophical disputes over the status of colors (for presentations of this taxonomy and apparatus see, for example, Byrne and Hilbert (2003); Cohen (2008b)).1 Therefore, the conclusion that sounds are distinctively temporal would be a serious blow to hopes for a theoretically unified treatment of the sensory qualities.2 For all these reasons, quite a lot seems to hang on the question of the temporality of sounds.

Content disjunctivism is the view that veridical experience involves contents and objects that differ from those of corresponding hallucinations. On one formulation of this view, we are aware of ordinary material things in our surroundings when we experience veridically, and we are aware of mere appearances when we hallucinate. This paper proposes a way of developing this view and offers some considerations in support. Central to the proposed regimentation will be a distinction between different notions of appearance. We distinguish between (...) the notion of something merely appearing to have a property and the notion of mere appearances, which are types of objects that we can refer to and be aware of. Mere appearances are not sense data or Meinongian non-existent objects but existing objects that do not have the properties that they appear to have. These notions of appearance will be elucidated, in particular by characterizing how they are involved in hallucination and illusion. I argue that the resulting view is supported by how our mental life seems to us when we experience our environment. (shrink)
