Some philosophers have argued that we do not hear sounds as located in the environment. Others have objected that this straightforwardly contradicts the phenomenology of auditory experience. And from this they draw metaphysical conclusions about the nature of sounds—that they are events or properties of vibrating surfaces rather than waves or sensations. I argue that there is a minimal, but recognizable, notion of audition to which this phenomenal objection does not apply. While this notion doesn’t correspond to our ordinary notion (...) of auditory experience, it does—in conjunction with our lack of an uncontroversial individuation of the senses and recent interest in distinctively multisensory features of perceptual experiences—raise the possibility of more expansive notions of audition, including some that do plausibly count as corresponding to our everyday notion of audition, that lack the spatial phenomenology cited in the objection. Until this possibility is ruled out, the phenomenal objection and metaphysical conclusions drawn from it remain inconclusive. (shrink)

Aristotle is history’s most famous and influential proponent of the view that there are exactly five senses. But was he entitled to hold this view, given his other commitments? In particular, was he entitled to treat touch as a single sense, given the diversity of its correlated objects? In this paper I argue that Aristotle wished to individuate touch on the basis of its correlated objects, just as he had the other four senses. I also argue, contrary to what is (...) often supposed, that he was well-placed to do so, given his other commitments and views. (shrink)

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 is the editors' Introduction to a special issue of the journal, Multisensory Research. European philosophers of the modern period found multisensory perception to be impossible because they thought that perceptual ideas are defined by how they are experienced. Under this conception, the individual modalities are determinables of ideas—just as colour is a determinable that embraces red and blue, so also the visual is a determinable that embraces colour and (visually experienced) shape. Since no idea is experienced as, for example, (...) both visual and auditory, there can be no such thing as audiovisual perception. This conception of modality is not directly contested, but a variety of perceptual phenomena are listed that could raise interesting questions if treated as multimodal in origin. (shrink)

Introduction to the topical collection "The Structure of Perceptual Objects"—with contributions by Mohan Matthen, EJ Green, Alisa Mandrigin, Blazej Skrzypulec, and Anna Drożdżowicz.

This paper presents an account of the senses and what differentiates them that is compatible with richly multisensory perception and consciousness. According to this proposal, senses are ways of perceiving. Each sense is a subfaculty that comprises a collection of perceptual capacities. What each sense shares and what differentiates one sense from another is the manner in which those capacities are exercised. Each way of perceiving involves a distinct type of information gathering, individuated by the information it functions to extract (...) and the medium from which it does so. This approach distinguishes the project of characterizing and differentiating senses from that of attributing experiences to sensory modalities. Perceptual experiences are episodes in which perceptual capacities are exer- cised. Conscious perceptual episodes may be ascribed to distinct sensory modalities, according to the manners in which perceptual capacities are deployed on an occasion. According to this account, senses are not exclusive. First, their capacities may overlap. Second, perceptual episodes, including conscious experiences, may belong to multiple senses. Indeed, some episodes require the joint use of several senses. In this account, subjects have only limited first-person knowledge of the senses they employ. (shrink)

Is the flavor of mint reducible to the minty smell, the taste, and the menthol-like coolness on the roof of one’s mouth, or does it include something over and above these—something not properly associated with any one of the contributing senses? More generally, are there features of perceptual experiences—so-called novel features—that are not associated with any of our senses taken singly? This question has received a lot of attention of late. Yet surprisingly little attention has been paid to the question (...) of what it means to say that a feature is associated with a sensory modality in the first place. Indeed, there is only one fully developed proposal in the literature, due to Casey O’Callaghan. I argue that this proposal is too permissive to inform the debate over novel features. I go on to argue that all attempts to formulate a better proposal along these lines fail. The corollary of my arguments is that the question of the existence of novel features is poorly formed. Furthermore, the problem generalizes, with the result that we should not rely on our pre-theoretical notions of the senses as the basis of theorizing about the features of perceptual experiences.

Harman famously argues that a particular class of antifunctionalist arguments from the intrinsic properties of mental states or events (in particular, visual experiences) can be defused by distinguishing “properties of the object of experience from properties of the experience of an object” and by realizing that the latter are not introspectively accessible (or are transparent). More specifically, Harman argues that we are or can be introspectively aware only of the properties of the object of an experience but not the properties (...) of the experience of an object and hence that the fact that functionalism leaves out the properties of the experience of an object does not show that it leaves out anything mentally relevant. In this paper, I argue that Harman’s attempt to defuse the anti-functionalist arguments in question is unsuccessful. After making a distinction between the thesis of experiencing-act transparency and the thesis of mental-paint transparency, (and casting some doubt on the former,) I mainly target the latter and argue that it is false. The thesis of mental-paint transparency is false, I claim, not because mental paint involves some introspectively accessible properties that are different from the properties of the objects of experiences but because what I call the identity thesis is true, viz. that mental paint is the same as (an array of) properties of the object of experience. The identification of mental paint with properties of the object of experience entails that the antifunctionalist arguments Harman criticizes cannot be rightly accused of committing the fallacy of confusing the two.

It’s often claimed in the philosophical and scientific literature on temporal representation that there is no such thing as a genuine sensory system for time. In this paper, I argue for the opposite—many animals, including all mammals, possess a genuine sensory system for time based in the circadian system. In arguing for this conclusion, I develop a semantics and meta-semantics for explaining how the endogenous rhythms of the circadian system provide organisms with a direct information link to the temporal structure (...) of their environment. In doing so, I highlight the role of sensory systems in an information processing architecture. (shrink)

Le sens commun distingue le corps de l’esprit. Il considère par exemple que les désirs et les souvenirs sont des phénomènes mentaux alors que les sons et les courants d’air sont des phénomènes physiques. Au sein de l’esprit, il distingue diverses facultés mentales : il considère par exemple que l’imagination est distincte de la volonté, qui est elle-même distincte de la perception. Au sein de la faculté perceptive, il distingue cinq sens : l’odorat, le goût, la vue, le toucher et (...) l’ouïe. Cette distinction entre différentes modalités perceptives s’avère tout à fait opératoire : nous n’avons le plus souvent aucun mal à répondre à la question « comment avez- vous perçu X : l’avez-vous vu, entendu, touché, ... ? ». En outre, cette distinction semble robuste : elle résiste par exemple à la co-occurrence d’expériences de modalités distinctes. Ainsi pouvons-nous voir et entendre un planeur à la fois. Enfin, nous semblons convaincus, en ce qui concerne les humains, du caractère exhaustif de cette distinction : il nous arrive certes de parler de l’intuition comme d’un sixième sens, ou de parler du sens de l’humour ou des affaires, mais ces expressions sont entendues en un sens figuré.

Intermodal representationalists hold that the phenomenal characters of experiences are fully determined by their contents. In contrast, intramodal representationalists hold that the phenomenal characters of experiences are determined by their contents together with their intentional modes or manners of representation, which are nonrepresentational features corresponding roughly to the sensory modalities. This paper discusses a kind of experience that provides evidence for an intermodal representationalist view: intermodal experiences, experiences that unify experiences in different modalities. I argue that such experiences are much (...) easier to explain on the intermodal view. (shrink)

A significant impediment to the study of perceptual consciousness is our dependence on simplistic ideas about what experience is like. This is a point that has been made by Wittgenstein, and by philosophers working in the Phenomenological Tradition, such as Husserl and Merleau-Ponty. Importantly, it is an observation that has been brought to the fore in recent discussions of consciousness among philosophers and cognitive scientists who have come to feel the need for a more rigorous phenomenology of experience. The central (...) thought of this paper is that art can make a needed contribution to the study of perceptual consciousness. The work of some artists can teach us about perceptual consciousness by furnishing us with the opportunity to have a special kind of reflective experience. In this way, art can be a tool for phenomenological investigation. The paper has three parts. First, I present what I call the problem of the transparency of experience. This is a problem for philosophy, for art, and for cognitive science. Second, I present an alternative conception of experience as a mode of interactive engagement with the environment. Finally, against the background of this conception, I discuss, briefly, the work of the sculptors Richard Serra and Tony Smith. (shrink)

The proper sensible criterion of sensory individuation holds that senses are individuated by the special kind of sensibles on which they exclusively bear about (colors for sight, sounds for hearing, etc.). H. P. Grice objected to the proper sensibles criterion that it cannot account for the phenomenal difference between feeling and seeing shapes or other common sensibles. That paper advances a novel answer to Grice's objection. Admittedly, the upholder of the proper sensible criterion must bind the proper sensibles –i.e. colors– (...) to the common sensibles –i.e. shapes– so as to account for the visual phenomenal character of shapes. But, as Grice rightly objected, neither association, nor ontological dependence will do –I spend some time isolating why dependence is a bad answer here, basically because the dependence of shape on colors is generic, and that genericity is arguably not part of the phenomenal content of perception. -/- Grice is wrong, however, to think that once association and dependence have been rebutted, there is no other way to attach color to extension. The right way to connect proper and common sensibles is rather trivial, although it seems to have been widely neglected: proper sensibles FILL common ones. To see a shape, by contrast to feeling it, is to perceived as filled by some color. To feel a shape, is to perceive it as, say, filled by pressure. Filling in is the phenomenal connection between proper and common sensibles. -/- One important corollary of that proposal is that proper sensibles –color, pressure, noise, taste...– have to belong to the category of stuffs, in the sense of uncountable entities. Against the widespread view that colors are properties, which have countable instances, the last part of the paper argues that colors are phenomenal stuffs, which fill some visual area. One commits a category mistake in asking: "How many tropes/instances of this determinate redness is there on that ladybird". One should rather ask "How much of this determinate redness is there on that ladybird". (shrink)

Ordinary Language Philosophy has largely fallen out of favour, and with it the belief in the primary importance of analyses of ordinary language for philosophical purposes. Still, in their various endeavours, philosophers not only from analytic but also from other backgrounds refer to the use and meaning of terms of interest in ordinary parlance. In doing so, they most commonly appeal to their own linguistic intuitions. Often, the appeal to individual intuitions is supplemented by reference to dictionaries. In recent times, (...) Internet search engine queries for expressions of interest have become quite popular. Apparently, philosophers attempt to surpass the limits of their own linguistic intuitions by appealing to experts or to factual uses of language. I argue that this attempt is commendable but that its execution is wanting. Instead of appealing to dictionaries or Internet queries, philosophers should employ computer-based linguistic corpora in order to confirm or falsify hypotheses about the factual use of language. This approach also has some advantages over methods employed by experimental philosophers. If the importance of ordinary language is stressed, the use of linguistic corpora is hardly avoidable.

It is tempting to hold that perceptual experience amounts to a co-conscious collection of visual, auditory, tactual, gustatory, and olfactory episodes. If so, each aspect of perceptual experience on each occasion is associated with a specific modality. This paper, however, concerns a core variety of multimodal perceptual experience. It argues that there is perceptually apparent intermodal feature binding. I present the case for this claim, explain its consequences for theorizing about perceptual experience, and defend it against objections. I maintain that (...) just as one thing may perceptually appear at once to jointly bear several features associated with the same sense modality, one thing also may perceptually appear at once to jointly bear features associated with different sense modalities. For instance, just as something may visually appear at once to be both red and round, or to have a red part and a green part, something may multimodally perceptually appear at once to be both bright and loud, or to have a red part and a rough part. The main lesson, I argue, is that perceiving is not just co-consciously seeing, hearing, feeling, tasting, and smelling at the same time. And perceptual phenomenal character is not on each occasion exhausted by that which is distinctive to or associated with a given modality, along with that which accrues thanks to simple co-consciousness. Not all ways of perceiving are modality specific. I defend this account against three main objections: that singular content theorists avoid my conclusions; that apparent infusion of perceptible features is required for perceptually apparent binding but does not occur intermodally; and that the diversity of objects across modalities makes perceptually apparent intermodal binding rare.

This report highlights and explores five questions that arose from the workshop on sensory substitution and augmentation at the British Academy, March 26th through 28th, 2013.

In this thesis I seek to advance our understanding of what intuitions are. I argue that intuitions are experiences of a certain kind. In particular, they are experiences with representational content, and with a certain phenomenal character. -/- In Chapter 1 I identify our target and provide some important reliminaries. Intuitions are mental states, but which ones? Giving examples helps: a person has an intuition when it seems to her that torturing the innocent is wrong, or that if something is (...) red it is coloured. We can also provide an initial characterisation of the state by saying that it has representational content, often causes belief, and appears to justify belief. In addition, there is something it is like to have an intuition: intuition has a certain phenomenal character. -/- Some argue that intuition does not explain anything which cannot be explained by other mental states. One version of this view takes intuition to reduce to belief. In Chapter 2 I argue that this entails that agents are rationally criticisable in situations where we know they are not, and that such views are therefore untenable. A parallel argument shows that the corresponding approach to perception fails. This suggests a similarity in nature: both intuition and perception are experiences. -/- Others take intuition to reduce to a disposition to have a belief. In Chapter 3 I consider a line of argument against such views, find it unsuccessful, and present two new arguments. One is likely to be dialectically ineffective. The other suffers no such weakness: it shows that the proposed reduction fails. As before, the argument also applies to perception, and suggests that intuition and perception are both experiences. -/- In the remainder of the thesis I develop an account of intuition as an experience. I distinguish between content-specific and attitude-specific phenomenology, and argue that intuition lacks the former (Chapter 4), but has the latter (Chapter 5). This allows us to say what intuition is: it is is an experience with representational content and with attitude-specific phenomenology of a certain kind. -/- In Chapter 6 I put this account of intuition to use. When a person has a perceptual or intuitional experience, I argue that simply having the experience is what makes the subject justified in believing what the experience represents. Moreover, what explains that intuition and perception can justify belief in this way is precisely their phenomenal character. (shrink)

Block (Trends Cogn Sci 7:285–286, 2003) and Prinz (PSYCHE 12:1–19, 2006) have defended the idea that SSD perception remains in the substituting modality (auditory or tactile). Hurley and Noë (Biol Philos 18:131–168, 2003) instead argued that after substantial training with the device, the perceptual experience that the SSD user enjoys undergoes a change, switching from tactile/auditory to visual. This debate has unfolded in something like a stalemate where, I will argue, it has become difficult to determine whether the perception acquired (...) through the coupling with an SSD remains in the substituting or the substituted modality. Within this puzzling deadlock two new approaches have been recently suggested. Ward and Meijer (Conscious Cogn 19:492–500, 2010) describe SSD perception as visual-like but characterize it as a kind of artificially induced synaesthesia. Auvray et al. (Perception 36:416–430, 2007) and Auvray and Myin (Cogn Sci 33:1036–1058, 2009) suggest that SSDs let their users experience a new kind of perception. Deroy and Auvray (forthcoming) refine this position, and argue that this new kind of perception depends on pre-existing senses without entirely aligning with any of them. So, they have talked about perceptual experience in SSDs as going "beyond vision". In a similar vein, MacPherson (Oxford University Press, New York, 2011a) claims that “if the subjects (SSD users) have experiences with both vision-like and touch-like representational characteristics then perhaps they have a sense that ordinary humans do not” (MacPherson in Oxford University Press, New York, 2011a, p. 139).

In his 1904 letter to G.F. Stout, Cook Wilson distinguishes objective and sub- jective conceptions of appearance, and provides a diagnosis for the modern acceptance of the subjective conception in terms of a confused misdescrip- tion of the objective appearances that perceptual experience affords. More- over, Cook Wilson links subjective appearances with idealism, the suggestion being that perceptual appearances must be objective if they are to afford us with something akin to proof of a world without the mind.

Molyneux’s question, whether the newly sighted might immediately recognize tactilely familiar shapes by sight alone, has produced an array of answers over three centuries of debate and discussion. I propose the first pluralist response: many different answers, both yes and no, are individually sufficient as an answer to the question as a whole. I argue that this is possible if we take the question to be cluster concept of sub-problems. This response opposes traditional answers that isolate specific perceptual features as (...) uniquely applicable to Molyneux’s question and grant viability to only one reply. Answering Molyneux’s question as a cluster concept may also serve as a methodology for resolving other philosophical problems. (shrink)

We begin with a theory of the structure of sensory consciousness; a target phenomenon of 'presentation' can be clearly located within this structure. We then defend the rational-psychological necessity of presentation. We conclude with discussion of these philosophical challenges to the possibility of presentation. One crucial aspect of the discussion is recognition of the <cite>nonobjectivity</cite> of consciousness (a technical appendix explains what I mean by that). The other is a full-faced stare at the limitations of rational psychology: much of the (...) dialectic in the philosophy of perception pertains to matters beyond the limits of coherence---a breakwater against which philosophy crashes, and rolls back.

This paper provides a categorization of cross-modal experiences. There are myriad forms. Doing so allows us to think clearly about the nature of different cross-modal experiences and allows us to clearly formulate competing hypotheses about the kind of experiences involved in different cross-modal phenomena.

In this paper I argue that olfactory experience, like visual experience, is exteroceptive: it seems to one that odours, when one smells them, are external to the body, as it seems to one that objects are external to the body when one sees them. Where the sense of smell has been discussed by philosophers, it has often been supposed to be non-exteroceptive. The strangeness of this philosophical orthodoxy makes it natural to ask what would lead to its widespread acceptance. I (...) argue that philosophers have been misled by a visuocentric model of what exteroceptivity involves. Since olfaction lacks the spatial features that make vision exteroceptive the conclusion that olfaction is nonexteroceptive can appear quite compelling, particularly in the absence of an alternative model of exteroceptivity appropriate to olfaction. I offer a model according to which odours seem to be external to the body because they seem to be brought into the nose from without by sniffing and breathing through the nostrils. I argue that some natural-seeming objections to this model rely on substantive assumptions about how the senses are distinguished from one another, and how perceptual experience is put together out of its modality-specific parts, that require defence.

A satisfactory solution to the problem of consciousness would take the form of a simple yet fully general model that specifies the precise conditions under which any given state of consciousness occurs. Science has uncovered numerous correlations between consciousness and neural activity, but it has not yet come anywhere close to this. We are still looking for the Newtonian laws of consciousness. -/- One of the main difficulties with consciousness is that we lack a language in which to formulate illuminating (...) generalizations about it. Philosophers and scientists talk about "what it’s like", sensations, feelings, and perceptual states such as seeing and hearing. This language does not allow a precise articulation of the internal structures of conscious states and their inter-relations. It is inadequate to capture relations of the kind we are looking for between conscious states and physical states. -/- In this thesis I refine and defend a theory of consciousness which promises to solve this regimentation problem: the representational theory of consciousness. I argue that the representational theory can solve the regimentation problem and smooth out other important obstacles to a fruitful study of consciousness. I also make a case for the theory independently of its payoffs, and I discuss the leading opposing theories at some length. (shrink)

Many spiritual traditions employ certain mental techniques (meditation) which consist in inhibiting mental activity whilst nonetheless remaining fully conscious, which is supposed to lead to a realisation of one’s own true nature prior to habitual self-substantialisation. In this paper I propose that this practice can be understood as a special means of becoming aware of consciousness itself as such. To explain this claim I conduct some phenomenologically oriented considerations about the nature of consciousness qua presence and the problem of self-presence (...) of this presence. (shrink)

If we assume that the operation of each sense modality constitutes a different experience – a visual experience, an auditory experience, etc – we are faced with the problem of how those distinct experiences come together to form a unified perceptual encounter with the world. Michael Tye has recently argued that the best way to get around this problem is to deny altogether that there are such things as purely visual (and so forth) experiences. Here I aim to show not (...) simply that Tye’s proposed solution fails, but that its failure is highly instructive because it allows us to see that the transparency thesis, which lies at the heart of the case against qualia, and of most representationalist theories of experience, is more problematic than is often supposed.

Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. Bodily sensations are typically attributed to bodily locations and appear to have features such as volume, intensity, duration, and so on, that are ordinarily attributed to physical objects or quantities. Yet these sensations are often thought to be logically private, subjective, self-intimating, and the source of incorrigible knowledge for those who have them. Hence there appear to (...) be reasons both for thinking that pains (along with other similar bodily sensations) are physical objects or conditions that we perceive in body parts, and for thinking that they are not. This apparent paradox is one of the main reasons why philosophers are especially interested in pain. One increasingly popular but still controversial way to deal with this apparent paradox is to defend a perceptual or representational view of pain, according to which feeling pain is in principle no different from undergoing other standard perceptual processes like seeing, hearing, touching, etc. But there are many who think that pains are not amenable to such a treatment. Although it was the treatment of pain as a sensory-discriminative experience that had dominated the philosophical discussions throughout most of the twentieth century, attention to pains’ affective-motivational dimension has gained prominence in recent years.

This paper (1) sketches a phenomenological analysis of visual mental imagery; (2) applies this analysis to the mental imagery debate in cognitive science; (3) briefly sketches a neurophenomenological approach to mental imagery; and (4) compares the results of this discussion with Dennett’s heterophenomenology.

This paper sketches a phenomenological analysis of visual mental imagery and uses it to criticize representationalism and the internalist-versus-externalist framework for understanding consciousness. Contrary to internalist views of mental imagery imagery experience is not the experience of a phenomenal mental picture inspected by the mind’s eye, but rather the mental simulation of perceptual experience. Furthermore, there are experiential differences in perceiving and imagining that are not differences in the properties represented by these experiences. Therefore, externalist representationalism, which maintains that the (...) properties of experience are the external properties represented by experience, is an inadequate account of conscious experience.

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

A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

Cross-modal perceptual illusions occur when a stimulus to one modality impacts perceptual experience associated with another modality. Unlike synaesthesia, cross-modal illusions are intelligible as results of perceptual strategies for dealing with sensory stimulation to multiple modalities, rather than as mere quirks. I argue that understanding cross-modal illusions reveals an important flaw in a widespread conception of the senses, and of their role in perceptual experience, according to which understanding perception and perceptual experience is a matter of assembling independently viable stories (...) about vision, audition, olfaction, and the rest. (shrink)

There has been some recent optimism that addressing the question of how we distinguish sensory modalities will help us consider whether there are limits on a scientific understanding of perceptual states. For example, Block has suggested that the way we distinguish sensory modalities indicates that perceptual states have qualia which at least resist scientific characterization. At another extreme, Keeley argues that our common-sense way of distinguishing the senses in terms of qualitative properties is misguided, and offers a scientific eliminativism about (...) common-sense modalities which avoids appeal to qualitative properties altogether. I’ll argue contrary to Keeley that qualitative properties are necessary for distinguishing senses, and contrary to Block that our common-sense distinction doesn’t indicate that perceptual states have qualia. A non-qualitative characterization of perceptual states isn’t needed to avoid the potential limit on scientific understanding imposed by qualia. (shrink)

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

Two questions are addressed in this paper. First, what is it to see? I argue that it is veridical experience of things outside the perceiver brought about by looking. Second, what is it to see a material object? I argue that it is experience of an occupant of a spatial region that is a logical subject for other visual features, able to move to another spatial region, to change intrinsically, and to interact with other material objects. I show how this (...) theory is different from the idea that object-seeing is merely the visual segregation of a region of the visual field. Finally, I argue that we do not object-see objects reflected in mirrors, surfaces of back-lit objects, and depictions of objects. (shrink)

The aim of this paper is to give a description of the objects of the sense of touch. Those objects, it is argued, are forces, rather than flesh deformation, solidity or weight. Tangible forces, basically tensions and pressures, are construed as symmetric and non-spatially reducible causal relations. Two consequences are drawn: first, the perception of heat and cold falls outside the sense of touch; second, muscular sense (together with a large part of proprioception) falls inside the sense of touch.

When a person has an intuition, it seems to her that things are certain ways; to many it seems that torturing the innocent for fun is wrong, for example. When a person has an intuition, there is also something particular it is like to be her: intuitions have a characteristic phenomenal character. This article asks how the phenomenal character of intuition is related to two core core questions in the philosophy of intuition, namely: Is intuition a source of justification and (...) knowledge? and What are intuitions?.

Distributive egalitarians believe that distributive justice is to be explained by the idea of distributive equality (DE) and that DE is of intrinsic value. The socio-relational critique argues that distributive egalitarianism does not account for the “true” value of equality, which rather lies in the idea of “equality as a substantive social value” (ESV). This paper examines the socio-relational critique and argues that it fails because – contrary to what the critique presupposes –, first, ESV is not conceptually distinct from (...) DE, and second, the idea of ESV cannot serve as a “foundation” or “root” of distributive egalitarianism. (shrink)

It is an integral part of the phenomenology of mature perceptual experience that it seems to present to us an experience-independent world. I shall call this feature 'perceptual intentionality'. In this paper, I argue that perceptual intentionality is constructed by the structure of more basic sensory features, features that are not intentional themselves. This theory can explain why the same sensory feature can figure both in presentational and non-presentational experiences. There is a fundamental difference between the intentionality of sensory experiences (...) and the intentionality of thoughts: unlike the former, the latter is not constructed. (shrink)

For the most part, philosophical discussion of the senses has been concerned with what distinguishes them from one another, following Grice’s treatment of this issue in his ‘Remarks on the senses’. But this is one of two questions which Grice raises in this influential paper. The other, the question of what distinguishes senses from faculties that are not senses, is the question I address in this thesis. Though there are good reasons to think that the awareness we have of our (...) bodies is perceptual, we do not usually think of bodily awareness as a sense. So in particular, I try to give an account of what it is that is distinctive about the five familiar modalities that they do not share with bodily awareness. I argue that what is distinctive about vision, touch, hearing, taste and smell, is that perception in all these modalities has enabling and disabling conditions of a certain kind. These enabling and disabling conditions are manifest in the conscious character of experience in these modalities, and exploited in active perceptual attention— in looking, listening, and so on. Bodily awareness has no such enabling conditions. The five familiar senses having this distinctive feature, and bodily awareness lacking it is not a merely incidental difference between them. Nevertheless, I do not claim that having these enabling conditions is necessary and sufficient for counting some faculty as a sense, or, correlatively, for something being an instance of sense-perception. Rather, we can see why it would serve certain human interests for us to think of the faculties that involve these enabling conditions as instances of a single kind of thing, of which bodily awareness is not an instance. (shrink)

I argue that we should reject the sparse view that there are or could be only a small number of rather distinct senses. When one appreciates this then one can see that there is no need to choose between the standard criteria that have been proposed as ways of individuating the senses—representation, phenomenal character, proximal stimulus and sense organ—or any other criteria that one may deem important. Rather, one can use these criteria in conjunction to form a fine-grained taxonomy of (...) the senses. We can think of these criteria as defining a multidimensional space within which we can locate each of the senses that we are familiar with and which also defines the space of possible senses there could be.

The discovery of mirror neurons has been hailed as one of the most exciting developments in neuroscience in the past few decades. These neurons discharge in response to the observation of others’ actions. But how are we to understand the function of these neurons? In this paper I defend the idea that mirror neurons are best conceived as components of a sensory system that has the function to perceive action. In short, mirror neurons are part of a hitherto unrecognized “sixth (...) sense”. In this spirit, research should move toward developing a psychophysics of mirror neurons. (shrink)

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether QST can deal with the challenges olfaction presents, we show how a quality space (QS) could be (...) constructed relying on olfactory perceptible properties and the olfactory mental qualities then defined by appeal to that QS of olfactory perceptible properties. We also consider how to delimit the olfactory QS from other modalities. We further apply QST to the role that experience plays in refining our olfactory discriminative abilities and the occurrence of olfactory mental qualities in non-conscious olfactory states. QST is shown to be fully applicable to and useful for understanding the complex domain of olfaction. (shrink)

When one contrasts pain with the classic five senses, discussions generally focus on vision, which is taken as the paradigmatic example of perception. An intentionalist might argue that if the phenomenal difference between feeling and seeing bodily disturbances cannot be explained at the level of the content, it can be so at the level of the mode of presentation, and more particularly at the level of the structure of the spatial phenomenology of pain. Here I will argue that the spatial (...) phenomenology of pain shares some key features with touch by contrast to sight, but these similarities should not make us neglect major differences between these two types of bodily sensations. I shall then draw the consequences of these differences for the awareness of one’s body as one’s own. In brief, to fix the boundaries of the body that one experiences as one’s own, one must answer two questions: where does the body stop, and the rest of world start? and what matters for self-preservation? I will suggest that touch primarily answers the first question, whereas pain primarily answers the second question. (shrink)

How should interaction between the senses affect thought about them? I try to capture some ways in which non sense-specific perception might be thought to make it impossible or pointless or explanatorily idle to distinguish between senses. This task is complicated by there being more than one view of the nature of the senses, and more than one kind of non sense-specific perception. I argue, in particular, that provided we are willing to forgo certain assumptions about, for instance, the relationship (...) between modes or kinds of experience, and about how one should count perceptual experiences at a time, at least one way of thinking about the senses survives the occurrence of various kinds of non sense-specific perception relatively unscathed.
