The first published paper on pulsars was entitled, by its five co-authors, “Observation of a Rapidly Pulsating Radio Source”. (Hewish, et al. 1968). The publication of this paper preceded by some months the coining of the word ‘pulsar’ to refer to such pulsating radio sources. Does it seem odd to talk of observing pulsars? It might seem so since much effort has subsequently gone into identifying pulsars with optically visible stars using conventional light, not radio, telescopes. We can say that (...) the moons of Jupiter are observable since either we can see them through a telescope or, at some future date, astronauts will be able to travel close enough to Jupiter to see its moons without visual aids.

When I am looking at an apple, I perceptually attribute certain properties to certain entities. Two questions arise: what are these entities (what is it that I perceptually represent as having properties) and what are these properties (what properties I perceive this entity as having)? This paper is about the former, less widely explored, question: what does our perceptual system attribute properties to? In other words, what are these ‘sensory individuals’. There have been important debates in philosophy of perception about (...) what sensory individuals would be the most plausible candidates for which sense modalities. The aim of this paper is to ask a related question about picture perception: what is the sensory individual of picture perception? When we look at a picture and see an apple depicted in it, what kind of entity do we see? What do we perceptually attribute properties to? I argue that the most straightforward candidates (ordinary objects, sui generis sensory individuals, no sensory individuals) are all problematic and that the most plausible candidate for the sensory individuals of picture perception are spatiotemporal regions.

In this paper I take up the task, begun by Lewis and Lewis in their seminal paper on the topic, of offering a theory of holes according to which a hole is simply its hole-lining. I begin by motivating the theory, arguing that it holds interest even absent its original animating concerns of nominalism and materialism, and present desiderata any such theory must satisfy. With this in place, I offer a definition both of a lining and of hole sameness, arguing (...) that these can overcome the most prominent standing objections to identifying holes with linings. Finally, I present a more powerful counterargument in the spirit of Casati and Varzi, and conclude with an emended version of the theory meeting all our earlier desiderata. I conclude by dispelling some possible worries about the nominalist and materialist credentials of my theory. (shrink)

Along with hallucinations and illusions, afterimages have shaped the philosophical debate about the nature of perception. Often referred to as optical or visual illusions, experiences of afterimages have been abundantly exploited by philosophers to argue against naïve realism. This paper offers an alternative account to this traditional view by providing a tentative account of the colors of the afterimages from an objectivist perspective. Contrary to the widespread approach to afterimages, this paper explores the possibility that the colors of afterimages are (...) not ontologically different from “ordinary” colors and that experiences of afterimages fail to provide a motivation for rejecting naïve realism.

This paper defends a view that falls somewhere between the two extremes of inflationary and deflationary accounts of holes, and it does so by rejecting the initial conceptualisation of holes in terms of absences. Once we move away from this conception, I argue, we can see that there are no special metaphysical problems associated with holes. Rather, whatever one’s preferred metaphysics of paradigm material objects, that account can equally be applied to holes. This means that like the deflationist, I am (...) entity monist: I reject the idea that there are any immaterial beings. On the other hand, like the inflationist I reject the idea that we should identify holes with parts or surfaces of paradigm objects. Like the inflationist, I hold that there exist entities in roughly the regions of space-time where pre-theoretically we would say there exist holes, and those entities are holes. Call this latter part of the view—that where the folk are apt to claim there is a hole, that hole has roughly the dimensions that the folk attribute to it—hole-instinctivism (the view that our instincts about hole location/dimension are roughly right). Ultimately I embrace hole conventionalism, a view that includes commitment to both entity monism and hole-instinctivism. According to hole conventionalism, holes are no more ontologically problematic than statues, nor are they of a fundamentally different ontological kind from statues. (shrink)

It is argued that seeing that P is a mode of knowing that P that is to be explained in terms of the exercise of visual-perceptual recognitional abilities. The nature of those abilities is described. The justification for believing that P, when one sees that P, is provided by the fact that one sees that P. Access to this fact is explained in terms of an ability to recognize of seen objects that one is seeing them. Reasons for resistance to (...) such an account are considered. The distinction between merely reasonable belief and well-founded belief is emphasised. (shrink)

It is often assumed that when we see common opaque objects in standard light this is in virtue of seeing their facing surfaces. Here I argue that we should reject that claim. Either we don't see objects' facing surfaces, or—if we hold on to the claim that we do see such things—it is at least not in virtue of seeing them that we see common opaque objects. I end by showing how this conclusion squares both with our intuitions and with (...) the facts of vision science. (shrink)

Abstract: Some propose that the question of how you know that James is angry can be adequately answered with the claim that you see that James is angry. Call this the Perceptual Hypothesis. Here, I examine that hypothesis. I argue that there are two different ways in which the Perceptual Hypothesis could be made true. You might see that James is angry by seeing his bodily features. Alternatively, you might see that James is angry by seeing his anger. If you (...) see that James is angry in the first way, your knowledge is inferential. If you see that James is angry in the second way, your knowledge is not inferential. These are different ways of knowing that James is angry. So the Perceptual Hypothesis alone does not adequately answer the question of how you know that fact. To ascertain how you know it, we need to decide whether or not you saw his anger. This is an epistemological argument. But it has consequences for a theory of perception. It implies that there is a determinate fact about which features of an object you see. This fact is made true independently of what you come to know by seeing. In the final section of the paper, I seek to undermine various ways in which the claim that you see James' anger may be thought implausible. (shrink)

In the first chapter of The Nature of Morality (1977), Gilbert Harman sets out what he takes to be the “basic issue” confronting moral philosophy: whether moral principles can be “tested and confirmed in the way that scientific principles can... out in the world” (3–4). Harman argues that they can’t be. In this paper I argue that if we reject the Harmanian view that confirmation is the converse of explanation, then we can agree with the naturalist realist on the basic (...) epistemological issue of whether moral principles can be tested and confirmed in the way that scientific principles can. But I argue that there nevertheless is an important metaphysical way in which moral explanations differ from certain kinds of non-moral explanations. An upshot is that even realists who think that moral facts are necessary, causally inefficacious, and knowable a priori can agree that moral claims are subject to empirical confirmation in the way that scientific claims are.

Many take the possibility of hallucinations to imply that a relationalist account, according to which perceptual experiences are constituted by direct relations to ordinary mind-independent objects, is false. The common reaction among relationalists is to adopt a disjunctivist view that denies that hallucinations have the same nature as perceptual experiences. This paper proposes a non-disjunctivist response to the argument from hallucination by arguing that the alleged empirical and a priori evidence in support of the possibility of hallucinations is inconclusive. A (...) corollary upshot of the article is that whether hallucinations are possible or not is still an open empirical question. (shrink)

Smells are often said to be ineffable, and linguistic research shows that languages like English lack a dedicated olfactory lexicon. Starting from this evidence, I propose an account of how we talk about smells in English. Our reports about the way things smell are comparative: When we say that something smells burnt or like roses, we characterise the thing's smell by noting its similarity to the characteristic smells of certain odorous things (burnt things, roses). The account explains both the strengths (...) and limitations of our smell discourse, and has implications for philosophical discussions of the relation between language and appearances. (shrink)

Although meritorious, Naïve Realism faces theoretical issues stemming from the lack of clarity in the concepts forming its propositions and the relevant (but not usually acknowledged) diversity of its theses. In this paper, my goal is to provide a groundwork that mitigates these theoretical complications. One such distinction concerns its subject matter, in particular, whether it deals with the nature of perceptual episodes or their phenomenology. My first goal is to acknowledge such distinctions by delimiting the former option, which I (...) refer to as “Ontological Naïve Realism”. To accomplish this, I proposed a distinctively minimal version of this position. However, a thorough characterization of the acquaintance relation was necessary for its postulation, which revealed a diversity of the corresponding relations/predicates. This informed the postulation of the minimal thesis and thus the definition of Ontological Naïve Realism. Based on this definition, I also proposed a novel classification and taxonomy of the relevant forms of Ontological Naïve Realism, based on the width of the attribution of naïve-realistic features and whether or not they identify perceptions/illusions to acquaintance instantiations.

The starting point of this paper is the thought that the phenomenal appearances that accompany mental states are somehow only there, or only real, from the standpoint of the subject of those mental states. The world differs across subjects in terms of which appearances obtain. Not only are subjects standpoints across which the world varies, subjects are standpoints that we can ‘adopt’ in our own theorizing about the world (or stand back from). The picture that is suggested by these claims (...) has an appeal but is at the same time obscure and stands in need of regimentation. This paper explores and motivates a metaphysical account of what it is for subjects to be standpoints, what it is to adopt standpoints in our representations and, most importantly, how these notions might help us better understand the subjective character of conscious mental states. Some well-known observations by Thomas Nagel serve as starting points and the paper concludes by revisiting Nagel’s argument for the inevitable incompleteness of objective accounts of mental states, which will be reframed in terms of the central commitments of the proposed framework.

Metaphysical views typically draw some distinction between reality and appearance, endorsing realism about some subject matters and antirealism about others. There are different conceptions of how best to construe antirealist theories. A simple view has it that we are antirealists about a subject matter when we believe that this subject matter fails to obtain. This paper discusses an alternative view, which I will call the fundamentality-based conception of antirealism. We are antirealists in this sense when we think that the relevant (...) matter fails to be constitutive of fundamental reality. The following discussion will not rely on any particular understanding of fundamental reality, covering conceptions based on grounding, naturalness and truthmaking, to name three salient ones. This paper argues that there are serious issues with fundamentality-based metaphysics. It will be argued that: the fundamentality-based approach shapes and restricts our realist and antirealist views in unsatisfying ways, that it is unable to handle the conflicting facts that lie across the envisaged ‘layers’ of the metaphysically structured world, and that the methodological reasons for adopting the fundamentality-based approach fail. The paper will conclude with a diagnosis of the discussed issues, identifying a common source. (shrink)

Universal reductionism—the sort of project pursued by Carnap in the Aufbau, Lewis in his campaign on behalf of Humean supervenience, Jackson in From Metaphysics to Ethics, and Chalmers in Constructing the World—aims to reduce everything to some specified base, more or less austere as it may be. In this paper, I identify two constraints that a promising strategy to argue for universal reductionism needs to satisfy: the exhaustion constraint and the chaining constraint. As a case study, I then consider Chalmers’ (...) Constructing the World, in which a priori implication, or “scrutability”, plays the role of reduction. Chalmers first divides up the total vocabulary of our language into different families, and then argues, for each family separately, that truths involving expressions in that family are scrutable from the putative base. He does not systematically address the question whether “cross-family sentences”—sentences involving expressions from more than one family—are scrutable. I shall argue that this lacuna cannot be filled, since scrutability does not allow for the exhaustion constraint and the chaining constraint to be jointly satisfied. I further suggest that Carnap’s account, in which definability plays the role of reduction, has better prospects of meeting these constraints. (shrink)

Increasingly prominent in the recent literature on the philosophy of perception, Intentionalism holds that sensory experience is inherently intentional, where to be intentional is to be about, or directed on, something. This article explores Intentionalism's prospects as a viable ontological and epistemological alternative to the traditional trinity of theories of sensory experience: the Sense-Datum Theory, the Adverbial Theory, and the Theory of Appearing.

How come we can represent Bigfoot even though Bigfoot does not exist, given that representing something involves bearing a relation to it and we cannot bear relations to what does not exist? This is the problem of intentional inexistence. This paper develops a two-step solution to this problem, involving an adverbial account of conscious representation, or phenomenal intentionality, and the thesis that all representation derives from conscious representation. The solution is correspondingly two-part: we can consciously represent Bigfoot because consciously representing (...) Bigfoot does not involve bearing a relation to Bigfoot, but rather instantiating a certain non-relational property of representing Bigfoot-wise; and we can non-consciously represent Bigfoot because non-consciously representing Bigfoot does not involve bearing a relation to Bigfoot, but rather bearing a relation to conscious representations of Bigfoot.

Virtually everyone agrees that, even after having presented the arguments for their positions, proponents of revisionary philosophical theories are required to provide some sort of account of the conflict between their theories and what the folk believe. I examine various strategies for answering the challenge from folk belief. The examination proceeds as a case study, whose focus is eliminativism about ordinary material objects. I critically assess eliminativist attempts to explain folk belief by appeal to paraphrase, experience, and intuition.

Jaakko Hintikka proposed treating objectual perception sentences, such as “Alice sees Bob,” as de re propositional perception sentences. Esa Saarinen extended Hintikka’s idea to eventive perception sentences, such as “Alice sees Bob smile.” These approaches, elegant as they may be, are not philosophically neutral, for they presuppose, controversially, that the content of all perceptual experiences is propositional in nature. The aim of this paper is to propose a formal treatment of objectual and eventive perception sentences that builds on Hintikka’s modal (...) approach to propositional attitude ascriptions while avoiding controversial assumptions on the nature of perceptual experiences. Despite being simple and theoretically frugal, our approach is powerful enough to express a variety of interesting philosophical views about propositional, objectual, and eventive perception sentences, thus enabling the study of their inferential relationships.

Color-vision defects constitute a spectrum of disorders with varying degrees and types of departure from normal human color vision. One form of color-vision defect is dichromacy; by mixing together only two lights, the dichromat can match any light, unlike normal trichromatic humans, who need to mix three. In a philosophical context, our titular question may be taken in two ways. First, it can be taken at face value as a question about visible properties of external objects, and second, it may (...) be interpreted as the more intangible question of “what it’s like” to be color-blind.

The aim of this paper is to argue that there is no unproblematic way of delineating perceptual beliefs from non-perceptual beliefs. The concept of perceptual belief is one of the central concepts not only of philosophy of perception but also of epistemology in a broad foundationalist tradition. Philosophers of perception talk about perceptual belief as the interface between perception and cognition and foundationalist epistemologists understand perceptual justification as a relation between perceptual states and perceptual beliefs. We consider three ways of (...) cashing out the difference between perceptual and non-perceptual beliefs (semantic, justificatory, and etiological) and argue that none of them works. Finally, we explore the possibility of understanding perceptual justification without relying on the concept of perceptual beliefs. (shrink)

According to the Matching Thesis (MT), the temporal structure of experience in time matches the apparent temporal structure of the objects and events represented in the content of perceptual experience. In this paper I critically address attempts to show the MT on the grounds that perceptual experience is transparent: that experiences themselves possess no introspectively discernible temporal structure apart from that of the apparent objects perceived. Pace such a Transparency Argument for the MT, I argue that considerations of perceptual transparency (...) can in fact ground no view about the relationship between the temporal structure of perceptual experiences and the apparent temporal structure of objects and events that experience represents. I defend this outcome against a line of objection having to do with self-knowledge. (shrink)

Because our only access to color qualities is through their appearance, Byrne & Hilbert's insistence on a strict distinction between apparent colors and real colors leaves them without a principled way of determining when, if ever, we see colors as they really are.

The argument from appearance for the content view or intentionalism attracts a lot of attention recently. In my paper, I follow Charles Travis to argue against the key premise that representational content can be ‘read off’ from a certain way that a thing looks to a subject. My arguments are built upon Travis’s original objection and a reinterpretation of Rodrick Chisholm’s comparative and noncomparative uses of appearance words. Byrne, Schellenberg and others interpret Travis’ ‘visual looks’ as Chisholm’s comparative use, and (...) appeal to the noncomparative use as an alternative to avoid Travis’s objection. I demonstrate that they misunderstand both Chisholm and Travis. Both the comparative use and the noncomparative use are semantic notions, while ‘visual looks’ is a metaphysical one. Although Chisholm’s appearance objectivism –– that appearance expressions attribute appearances to ordinary objects –– is close to ‘visual looks’, appearance objectivism is not exceptional to the noncomparative use as Byrne interprets. In the end, I also show that Byrnean’s conception of distinctive visual gestalt cannot exclude contrary representational contents, because a distinctive visual gestalt can be shared by different kinds of things. Besides, Byrne and others do not explain why a distinctive visual gestalt should be presented as ‘being instantiated’. Therefore, I conclude that representational content cannot be read off from a certain way that a thing looks to a subject; the argument from appearance thus fails. (shrink)

Adverbialist theories of thought such as those advanced by Hare and Sellars promise an ontologically sleek understanding of a variety of intentional states, but such theories have been largely abandoned due to the ‘many-property problem’. In an attempt to revitalize this otherwise attractive theory, in a series of papers as well as his recent book, Uriah Kriegel has offered a novel reply to the ‘many-property problem’ and on its basis he argues that ‘adverbialism about intentionality is alive and well’. If (...) true, Kriegel will have shown that the logical landscape has long been unnecessarily constrained. His key idea is that the many-property problem can be overcome by appreciating that mental states stand in the determinable–determinate relation to one another. The present paper shows that this relation can’t save adverbialism because it would require thinkers to think more thoughts than they need be thinking. (shrink)

Objects are central in visual, auditory, and tactual perception. But what counts as a perceptual object? I address this question via a structural unity schema, which specifies how a collection of parts must be arranged to compose an object for perception. On the theory I propose, perceptual objects are composed of parts that participate in causally sustained regularities. I argue that this theory falls out of a compelling account of the function of object perception, and illustrate its applications to multisensory (...) perception. I also argue that the account avoids problems faced by standard views of visual and auditory objects. (shrink)

One of Mark Textor’s main aims in Brentano’s Mind is to refute Brentano’s claim that intentionality – the capacity our mental acts have for being of, about, or directed on something – is the mark of the mental. I defend the view that Brentano analysed intentionality in terms of intentional inexistence (and so wasn’t an intentionality primitivist as Textor suggests). And I argue that we can regard intentionality as being the mark of the mental, but only if we give a (...) non-relational analysis of the idea of intentional inexistence. Textor objects to an analysis of intentionality in terms of intentional inexistence for failing to account for the relationship between the object our mental act is directed on, and the ‘immanent’ or ‘inexistent’ object which all mental acts contain. I claim that this problem doesn’t arise if the object our mental act is directed on just is the immanent/ inexistent object. I argue that Brentano (at least sometimes) seems to identify the two. I then offer my own view of intentionality according to which our mental acts are directed on immanent/ inexistent objects, and that ‘directedness’ should be understood non-relationally. (shrink)

All non-relational views of perceptual experience face Jackson's famous many-property problem. I argue that the original problem, and the existing responses to it, have focused too closely on the controversial terminology for which adverbialism is best known. We can also direct Jackson's many-property problem explicitly onto the adverbialist's metaphysics, generating a new challenge. The responses contemporary adverbialists and non-relationalists have made to the original objection are not successful against this challenge. We need a new non-relational account. I sketch an outline (...) of a new theory, and motivate the view by explaining how it can respond successfully to this additional challenge. -/- . (shrink)

The primary goal of this paper is to provide substantial motivation for exploring an Acquaintance account of phenomenal consciousness, on which what fundamentally explains phenomenal consciousness is the relation of acquaintance. Its secondary goal is to take a few steps towards such an account. Roughly, my argument proceeds as follows. Motivated by prioritizing naturalization, the debate about the nature of phenomenal consciousness has been almost monopolized by representational theories. Among them, Self-Representationalism is by far the most antecedently promising. However, on (...) thorough inspection, Self-Representationalism turns out not explanatorily or theoretically better than the Acquaintance account. Indeed, the latter seems to be superior in at least some important respects. Therefore, at the very least, there are good reasons to take the Acquaintance account into serious consideration as an alternative to representational theories. The positive contribution of this paper is a sketch of an account of consciousness on which phenomenal consciousness is explained partly in representationalist terms, but where a crucial role is played by the relation of acquaintance.

Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...) with pupillometry to document this “salience bias.” We find that under certain conditions, competent speakers automatically make stereotypical inferences they know to be inappropriate.

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.

Intuitive judgments elicited by verbal case-descriptions play key roles in philosophical problem-setting and argument. Experimental philosophy's ‘sources project’ seeks to develop psychological explanations of philosophically relevant intuitions which help us assess our warrant for accepting them. This article develops a psycholinguistic explanation of intuitions prompted by philosophical case-descriptions. For proof of concept, we target intuitions underlying a classic paradox about perception, trace them to stereotype-driven inferences automatically executed in verb comprehension, and employ a forced-choice plausibility-ranking task to elicit the relevant (...) stereotypical associations of perception- and appearance-verbs. We obtain a debunking explanation that resolves the philosophical paradox. (shrink)

The dream sceptic argues that our ordinary beliefs are not justified because we cannot know that we have not always been dreaming. This is the Always Dreaming Hypothesis (ADH). I develop the traditional coherence objection to dream scepticism and argue that the coherence objection can be reformulated in a way that makes it both plausible and defensible. Considerations about the incoherence of dreams can be given probabilistic expression in a way that shows ADH to be highly improbable. Given the evidence (...) of coherence, ADH can be rationally rejected. Even if ADH is augmented with causal information sufficient to account for the coherence and order of conscious experience, the resulting dream scepticism would then reduce to a BIV-type scepticism and thus fail to possess independent sceptical force.

Byrne & Hilbert defend color realism, which assumes that: (a) colors are properties of objects; (b) these objects are physical; hence, (c) colors are physical properties. I accept (a), agree that in a certain sense (b) can be defended, but reject (c). Colors are properties of perceptual objects – which also have underlying physical properties – but they are not physical properties.

Research in vision science, developmental psychology, and the foundations of cognitive science has led some theorists to posit referential mechanisms similar to indices. This hypothesis has been framed within a Fodorian conception of the early vision module. The article shows that this conception is mistaken, for it cannot handle the ‘interface problem’—roughly, how indexing mechanisms relate to higher cognition and conceptual thought. As a result, I reject the inaccessibility of early vision to higher cognition and make some constructive remarks on (...) the perception–cognition interface. -/- 1 The Case for Visual Indices 1.1 Preliminary assumptions 1.2 Transcendental arguments 1.3 Evidence from vision science 2 Visual Indices, Object Files, and Fodorian Modularity 3 The Interface Problem 3.1 Top-down attention and modularity 3.2 Selective attention and information 4 Revising the Indexing Hypothesis 4.1 Revising the perception–cognition interface 4.2 Revising the modularity of early vision 5 Concluding Remarks.

One increasingly popular view in the philosophy of perception isexternalismabout sensible qualities, according to which sensible qualities such as colors, smells, tastes, and textures are features, not of our minds, but of mind-independent, external objects in the world. The primary motivation for this view is that perceptual experience seems to betransparent—that is, when we attend to sensible qualities, it seems like what we are attending to are features of external objects, not our own minds. Most (if not all) externalists are (...) either naïve realists or externalist representationalists. However, in this article, I argue that those who are moved by the primary motivation for externalism should instead be sense-datum theorists, for externalists’ primary motivation supports the sense-datum theory, not their actually favored views. I argue that externalists should focus on different motivations, get new ones, or become sense-datum theorists. (shrink)

In this paper we set out a view on which internalist proper basicality is secured by sensory experience.

Let's be externalists about perceptual consciousness and think the form of veridical perceptual consciousness includes /seeing this or that mind-independent particular and its colors/. Let's also take internalism seriously, granting that spectral inversion and hallucination can be "phenomenally" the same as normal seeing. Then perceptual consciousness and phenomenality are different, and so we need to say how they are related. It's complicated!<br><br>Phenomenal sameness is (against all odds) /reflective indiscriminability/. I build a "displaced perception" account of reflection on which indiscriminability stems (...) from shared "qualia". Qualia are compatible with direct realism: while they generate an explanatory gap (and colors do not), so does /seeing/; qualia are excluded from perceptual consciousness by its "transparency"; instead, qualia are aspects of thought about the perceived environment. <br><br>The asymmetry between my treatments of color and seeing is grounded in the asymmetry between ignorance and error: while inversion shows that normal subjects are ignorant of the natures of the colors, hallucination shows not that perceivers are ignorant of the nature of seeing but that hallucinators are prone to error about their condition. Past literature has treated inversion and hallucination as on a par: externalists see error in both cases, while internalists see mutual ignorance. My account is so complicated because plausible results require mixing it up. (shrink)

Experimental philosophy’s much-discussed ‘restrictionist’ program seeks to delineate the extent to which philosophers may legitimately rely on intuitions about possible cases. The present paper shows that this program can be (i) put to the service of diagnostic problem-resolution (in the wake of J.L. Austin) and (ii) pursued by constructing and experimentally testing psycholinguistic explanations of intuitions which expose their lack of evidentiary value: The paper develops a psycholinguistic explanation of paradoxical intuitions that are prompted by verbal case-descriptions, and presents two (...) experiments that support the explanation. This debunking explanation helps resolve philosophical paradoxes about perception (known as ‘arguments from hallucination’). (shrink)

It will be obvious to anyone with a slight knowledge of twentieth-century analytic philosophy that one of the central themes of this kind of philosophy is the nature of perception: the awareness of the world through the five senses of sight, touch, smell, taste, and hearing. Yet it can seem puzzling, from our twenty-first-century perspective, why there is a distinctively philosophical problem of perception at all. For when philosophers ask ‘what is the nature of perception?’, the question can be confused (...) with other, purely empirical, questions. For example: how do our sense-organs actually work? What are the mechanisms of smell and taste? How do vision and touch actually provide us with information about the world around us? There is much general agreement, in its broad outlines, about how to answer such questions empirically; but it is not clear what role, if any, philosophy has to play in answering these empirical questions. So if these were the only questions about the nature of perception, then it would not be clear exactly what the philosophy of perception is supposed to be about. (shrink)

My main aim is to clarify what we mean by ‘look’ sentences such as (1) below – ones that we use to talk about visual experience: -/- (1) The ball looked red to Sue -/- This is to help better understand a part of natural language that has so far resisted treatment, and also to help better understand the nature of visual experience. -/- By appealing to general linguistic principles I argue for the following account. First, we use (1) to (...) talk about an event. Second, we use the verb ‘look’ to specify the kind of event about which we are talking – it is a looking event. Third, we use the subject ‘the ball’ to specify a stimulus of the event – something that looks some way in the event. Fourth, we use the adjunct ‘to Sue’ to specify an experiencer of the event – someone to whom things look some way in the event. Finally, we use the complement ‘red’ to specify a way of the event – a way in which the event occurs (I take ways of occurring to be properties of events). Which way do we use ‘red’ in (1) to specify? I argue: the maximally specific way w such that the following is generically true: looking events whose stimulus is red occur in way w (it is important that this is understood generically: this is what does much of the work in explaining our use of (1) and other ‘look’ sentences). Putting this together, what we mean by (1) is: there was a looking event whose stimulus was the ball, whose experiencer was Sue, and which occurred in the maximally specific way that looking events occur when their stimulus is red. -/- This account of how we use ‘red’ in (1) is one of the most interesting aspects of my thesis. It extends to an account of how we use ‘proud’ in ‘John walks proud’, ‘as if he is American’ in ‘John talks as if he is American’, ‘like a duck’ in ‘John sounds like a duck’, and so on. In each case we use the expression in question to specify a way: the maximally specific way proud people walk, the maximally specific way American people talk, and so on. So the study of ‘look’ sentences has much to tell us about the functioning of many other English language constructions, and suggests that ways have a significant role to play in the semantics of natural language – a fact that has not yet been sufficiently recognised by linguists or philosophers of language. -/- My thesis also has implications for the philosophy of perception. One of the central questions about perception is: What is the nature of visual experience? What is it, for example, for a ball to look red to Sue? My thesis offers an answer: What it is for the ball to look red to Sue is for whatever it is that we mean by ‘The ball looks red to Sue’ to be the case, and what we mean by ‘The ball looks red to Sue’ is that there is a looking event whose stimulus is the ball, whose experiencer is Sue, and which is occurring in a certain way. It thus delivers an adverbial account of visual experience, one that has the resources to better deal with problems that are traditionally thought to be decisive against adverbial accounts. (shrink)

The de nition of qualia — a contribution to logical philosophy In my article, I propose an abstract de nition of a quale, which (generally speaking) identi es qualia with sets belonging to certain relational structures. I maintain that my de nition, by not taking advantage of psychological terms, makes the notion of a quale more understandable and the existence of qualia themselves less disputable than is commonly supposed. In addition, I brie y discuss the traditional concept of a quale.

Philosophers think of pain less and less as a paradigmatic instance of mentality, for which they seek a general account, and increasingly as a rich and fruitful topic in its own right. Pain raises specific questions: about mentality and consciousness certainly, but also about embodiment, affect, motivation, and value, to name but a few. The growth of philosophical interest in pain has gone hand-in-hand with the growth of pain science, which burgeoned in the 1960s. This is no accident: developments in (...) pain science have prompted philosophers to take account of empirical data, and to revisit their assumptions about pain. Pain, in short, demands interdisciplinary investigation, hence while this entry focuses on the philosophy of pain, it makes liberal reference to empirical literature along the way. This entry’s focus is on physical pains, that is pains that are felt in bodily locations, not emotional suffering more broadly, such as grief or disappointment. The entry also does not address pain’s place in ethical theories; its focus is rather on issues that arise within philosophy of mind. Even so, part of what makes pain such an interesting and important topic is that the questions it raises span boundaries, and normative questions concerning pain’s badness, on the one hand, and its value, on the other, are never far away.
