The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in (...) the mind." The article has two other purposes: first, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate.

Anything is similar to anything, provided the respects of similarity are allowed to be gerrymandered or gruesome, as Goodman observed.2 But similarity in non-gruesome or—as I shall say—genuine respects is much less ecumenical. Colors, it seems, provide a compelling illustration of the distinction as applied to similarities among properties.3 For instance, in innumerable gruesome respects, blue is more similar to yellow than to purple. But in a genuine respect, blue is more similar to purple than to yellow (genuinely more similar, (...) as I shall sometimes put it). (shrink)

Byrne & Hilbert (B&H) assert that reflectances embody the reality of color, but metamerism smears the authors' “real” color categories into uselessness. B&H ignore this problem, possibly because they implicitly adopt a sort of subjectivism, whereby an object is defined by the percepts (or more generally by the measurements) it engenders. Subjectivism is unwieldy, and hence prone to such troubles.

Realism concerning a given domain of things is the view that the things in that domain exist, and are as they are, quite independently of anyone.

The standard paradigm for mental causation is a person’s acting for a reason. Something happens - she intentionally φ’s - the occurrence of which we explain by citing a relevant belief or desire. In the present context, I simply take for granted the following two conditions on the appropriateness of this explanation. First, the agent φ’s _because_ she believes/desires what we say she does, where this is expressive of a _causal_ dependence.1 Second, her believing/desiring this gives her a _reason_ for (...) φ-ing: recognizing that she has this belief/desire makes her φ-ing intelligible as rational in the light of her other attitudes and circumstances. A further condition must be met, though, if this is to be a genuine psychological explanation, a case of her acting _for_ the reason in question. Consider the following example of Davidson’s (1973, p. 79). An exhausted climber is desperate to rid herself of the weight and danger of holding her partner on a rope; and her sudden realization that simply letting go would achieve this so unnerves her that her grip loosens slightly and he falls. Her releasing him causally depends upon her having this belief and desire, which provide _a_ reason for doing what she does. But this is not _why_ she does it: it would be at best misleading to say that she dropped him, intentionally, because she was fed up with holding his weight, or because she thought that she might otherwise fall. Her letting go does not depend upon her having these reasons in the right way. The reason-giving relation is causally irrelevant. If we are to explain a person’s acting _for_ a reason, then her doing. (shrink)

Primitivism is the view that colors are sui generis properties of physical objects. The basic insight underlying primitivism is that colours are as we see them, i.e. they are categorical properties of physical objects—simple, monadic, constant, etc.—just like shapes. As such, they determine the content of colour experience. Accepting the premise that colours are sui generis properties of physical objects, this paper seeks to show that ascribing primitive properties to objects is, ipso facto, ascribing to objects irreducible dispositions to look (...) coloured, and that anything that primitive redness can do, the non-reductive disposition to look red can do just as well. What makes primitivism suspect is not the commitment to sui generis properties, but instead the claim that colours are more than dispositions. Since, as I show, whatever primitivism appeals to for the purpose of arguing that colours are more than dispositions—objectivity, explanation, causation, phenomenology, constancy, etc.—can also be invoked...

The argument from causal overdetermination is considered to be the shortest route to token monism. It only assumes that:1.Efficacy: Mental events are causes of physical events.2.Closure: Every physical event has a sufficient physical cause.3.Exclusion: Systematic Causal Overdetermination is impossible: if an event x is a sufficient cause of an event y then no event x* distinct from x is a cause of y.4.Identity: Therefore, mental events are physical events.Exclusion does not deny the possibility of two gunmen that fi re at (...) a victim at the same time. But event-dualism is like a systematic fi ringsquad case — whenever I want to raise my arm, my arm is raised, and that is intolerable. (shrink)

Here, I consider Derek Parfit’s Normativity Objection to naturalist realism, according to which normative-natural property or fact reductions are “conceptually excluded”. While a lot of philosophers inclined toward non-naturalism share this view or something close to it, plenty of philosophers remain unconvinced, and the literature offers little guidance to the perplexed. I suggest a way to improve the argument – indeed, I think it is the best and perhaps only plausible way to make good on the claim of conceptual exclusion. (...) But the improved argument relies on the highly controversial claim that normative cognition is transparentin the following sense: normative concepts reveal the nature of the properties they aim to ascribe. This nature, the argument continues, is inconsistent with naturalist strictures. (shrink)

Perceptions are externally-directed—they present us with a mind-independent reality, and thus contribute to our abilities to think about this reality, and to know what is objectively the case. But perceptions are also internally-dependent—their phenomenologies depend on the neuro-computational properties of the subject. A good theory of perception must account for both these facts. But naive realism has been criticized for failing to accommodate internal-dependence. This paper evaluates and responds to this criticism. It first argues that a certain version of naive (...) realism, often called “selectionism”, does indeed struggle with internal-dependence. It then develops an alternate version of naive realism which does not. This alternate version, inspired by an idea of Martin’s, accommodates the internal-dependence of perceptions by recognizing the role that the subject’s neuro-computational properties play in shaping perceptual phenomenology. At the same time, it retains the distinctive naive realist account of the external-directedness of perceptions. (shrink)

Beat perception has received very little attention from either philosophers of mind or philosophers of music. This neglect is unfortunate, for the topic is rich with philosophical interest. This article addresses two questions. The first concerns the nature of our experience of musical beat. Here, we argue that experiences of beat are forms of auditory perception. The second question concerns the nature of musical beat itself: what are beats? We defend a form of anthropocentric realism about beats: beats are mind‐independent (...) properties of sound sequences whose nature can be understood only in relation to our perceptual capacities.

In philosophical discussions of the secondary qualities, color has taken center stage. Smells, tastes, sounds, and feels have been treated, by and large, as mere accessories to colors. We are, as it is said, visual creatures. This, at least, has been the working assumption in the philosophy of perception and in those metaphysical discussions about the nature of the secondary qualities. The result has been a scarcity of work on the “other” secondary qualities. In this paper, I take smells and (...) place them front and center. I ask: What are smells? For many philosophers, the view that colors can be explained in purely physicalistic terms has seemed very appealing. In the case of smells, this kind of nonrelational view has seemed much less appealing. Philosophers have been drawn to versions of relationalism—the view that the nature of smells must be explained (at least in part) in terms of the effects they have on perceivers. In this paper, I consider a contemporary argument for this view. I argue that nonrelationalist views of smell have little to fear from this argument. (shrink)

I defend externalism about color experiences and color thoughts, which I argue color objectivism requires. Externalists face the following question: would a subject's wearing inverting lenses eventually change the color content of, for instance, those visual experiences the subject reports with “red”? From the work of Ned Block, David Velleman, Paul Boghossian, Michael Tye, and Fiona Macpherson, I extract problems facing those who answer “Yes” and problems facing those who answer “No.” I show how these problems can be overcome, leaving (...) externalism available to the color objectivist. (shrink)

To identify the set of reflectances that constitute redness, the authors must first determine which surfaces are red. They do this by relying on widespread agreement among us. However, arguments based on the possible ways in which humans would perceive colors show that mere widespread agreement among us is not a satisfactory way to determine which surfaces are red.

The view that the mind-dependence of colour is implicit in our ordinary thinking has a distinguished history. With its origins in Berkeley, the view has proved especially popular amongst so-called ‘Oxford’ philosophers, proponents including Cook Wilson (1904: 773-4), Pritchard (1909: 86-7), Ryle (1949: 209), Kneale (1950: 123) and McDowell (1985: 112). Gareth Evans’s discussion of secondary qualities in “Things Without the Mind” is representative of this tradition. It is his version of the view that I consider in this paper.

According to naïve realist (or primitivist) theories of colour, colours are sui generis mind-independent properties. The question that I consider in this paper is the relationship of naïve realism to what Mark Johnston calls Revelation, the thesis that the essential nature of colour is fully revealed in a standard visual experience. In the first part of the paper, I argue that if naïve realism is true, then Revelation is false. In the second part of the paper, I defend naïve realism (...) against a number of objections.

Inter-species variation in colour perception poses a serious problem for the view that colours are mind-independent properties. Given that colour perception varies so drastically across species, which species perceives colours as they really are? In this paper, I argue that all do. Specifically, I argue that members of different species perceive properties that are determinates of different, mutually compatible, determinables. This is an instance of a general selectionist strategy for dealing with cases of perceptual variation. According to selectionist views, objects (...) simultaneously instantiate a plurality of colours, all of them genuinely mind-independent, and subjects select from amongst this plurality which colours they perceive. I contrast selectionist views with relationalist views that deny the mind-independence of colour, and consider some general objections to this strategy. (shrink)

Colours appear to instantiate a number of structural properties: for instance, they stand in distinctive relations of similarity and difference, and admit of a fundamental distinction into unique and binary. Accounting for these structural properties is often taken to present a serious problem for physicalist theories of colour. This paper argues that a prominent attempt by Byrne and Hilbert to account for the structural properties of the colours, consistent with the claim that colours are types of surface spectral reflectance, is (...) unsuccessful. Instead, it is suggested that a better account of the structural properties of the colours is provided by a form of non-reductive physicalism about colour: a naïve realist theory of colour, according to which colours are superficial mind-independent properties. (shrink)

Pautz has argued that the most prominent naive realist account of hallucination—negative epistemic disjunctivism—cannot explain how hallucinations enable us to form beliefs about perceptually presented properties. He takes this as grounds to reject both negative epistemic disjunctivism and naive realism. Our aims are two: First, to show that this objection is dialectically ineffective against naive realism, and second, to draw morals from the failure of this objection for the dispute over the nature of perceptual experience at large.

According to a common philosophical intuition, the deep nature of things is hidden from us, and the world as we know it through perception and science is somehow shallow and lacking in reality. For all we knwo, the intuition goes, we could be living in a cave facing shadows, in a dream or even in a computer simulation, This “intuition of unreality” clashes with a strong, but perhaps more naive, intuition to the effect that the world as we know it (...) seems perfectly real. Shadows, dreams, or informational structures appear too unreal to be identical to the world as we know it! This clash between the two intuitions forms the basis of the "problem of reality." At the turn of the nineteenth century psychiatrists encountered patients they referred to as “metaphysician doubters” who constantly questioned the reality of the world. This essay draws on the study of these patients to reject, and indeed diagnose, the intuition of unreality and recent metaphysical doctrines drawing on it, such as structuralism, digitalism, and virtual realism.

In this paper, I argue for a version of panpsychist idealism on first-person experiential grounds. As things always appear in my field of consciousness, there is prima facie empirical support for idealism. Furthermore, by assuming that all things correspond to a conscious perspective or perspectives (i.e., panpsychism), realism about the world is arguably safeguarded without the need to appeal to God (as per Berkeley’s idealism). Panpsychist idealism also has a phenomenological advantage over traditional panpsychist views as it does not commit (...) perceptual experience to massive error by denying that perceived colours are properties of things. Finally, I argue that the subject combination problem for panpsychism has been motivated by the problematic assumption that consciousness is in things. Thinking about subject combination from the first-person perspective is fruitful for reframing the subject combination problem and for seeing how subjects could potentially combine for the idealist.

The nature of the colors—what they are like, whether they are instantiated by objects or are projected by our minds, whether their nature is revealed to us in color perception, and whether there could be alien colors (e.g. reddish-green)—has been one of the central topics in philosophy for centuries. This entry focuses on the contemporary philosophical debate about the nature of the colors.

Perspectivalism is a semantic theory according to which the contents of utterances and mental states (perhaps of a particular kind) have a truth-value only relative to a particular perspective (or standard) determined by the context of the speaker, assessor, or bearer of the mental state. I have defended this view for epistemic terms, moral terms and predicates of personal taste elsewhere (Brogaard 2008a, 2008b, forthcoming a). The main aim of this paper is to defend perspectivalism about color perception and color (...) discourse. The content of color perception and color discourse, I will argue, has a truth-value only relative to an appropriate viewing condition and the perceiver, or a perceiver deferred to. (shrink)

Some philosophical theories of the nature of color aim to respect a "common sense" conception of color: aligning with the common sense conception is supposed to speak in favor of a theory and conflicting with it is supposed to speak against a theory. In this paper, we argue that the idea of a "common sense" conception of color that philosophers of color have relied upon is overly simplistic. By drawing on experimental and historical evidence, we show how conceptions of color (...) vary along several dimensions and how even supposedly "core" components of the contemporary "common sense" conception of color are less stable than they have been thought to be.

The space of possible worlds is vast. Some of these possible worlds are materialist worlds, some may be worlds bottoming out in 0s and 1s, or other strange things we cannot even dream of… and some are idealist worlds. From among all of the worlds subjectively indistinguishable from our own, the idealist ones have uniquely compelling virtues. Idealism gives us a world that is just as it appears; a world that’s fit to literally enter our minds when we perceive it. (...) If the world is an idealist world, we live in a perceptual Eden. We did not fall from Eden. Rather, we deluded ourselves into believing that we couldn’t possibly live in Eden when we committed to materialism. Reflecting on these big-picture issues gives us reason to question this commitment and embrace a radically new account of reality and our relation to it. (shrink)

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was also very influential (...) in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

This paper illustrates what a philosophical and a logical investigation of colors amounts to in contrast to other kinds of color analysis such as physical, physiological, chemical, psychological or cultural analysis of colors. Neither a philosophical nor a logical analysis of colors is concerned with specific aspects of colors. Rather, these kinds of color analysis are concerned with what one might call “logical foundations of color theory”. I will illustrate this first by considering philosophical and then logical analysis of colors.

This collection brings together a selection of my recently published or forthcoming articles. What unites them is their common concern with one of the central ambitions of philosophy, namely to get clearer about our first-personal perspective onto the world and our minds. Three aspects of that perspective are of particular importance: consciousness, intentionality, and rationality. The collected essays address metaphysical and epistemological questions both concerning the nature of each of these aspects and concerning the various connections among them. More generally, (...) given that intentionality and ratio- nality are both normative phenomena, the main theme of the articles is the relationship between consciousness and normativity and the centrality of this relationship to our first-personal perspective. -/- This focus culminates in the defense of two specific views, experiential rationalism and experiential intentionalism. The first is, very roughly, the view that how our mental episodes are given in consciousness reflects their rational role in our mental lives: it is part of what our mental episodes subjectively are like that we phenomenally experience them as providing and/or responding to certain kinds of reasons. The central claim of the second view, on the other hand, is that the intentionality of our mental episodes is essentially linked to consciousness and involves a token-reflexive element: they intentionally present not only the world, but also themselves as being a certain way. -/- Some of the essays also deal with the contrast between our first- and our third-personal perspectives and the — to some extent related — division of labour between philosophy and the empirical sciences. Both perspectives have their limitations and sometimes conflict with each other, raising the question of what the consequences are for accounts of our first-personal knowledge and its internal or external objects.

I argue that it is metaphysically necessary that: (i) every fundamental entity is conscious, and (ii) every fundamental property is a phenomenal property.

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

Humeans and non-Humeans reasonably agree that there may be necessary connections between entities that are identical or merely partly distinct—between, e.g., sets and their individual members, fusions and their individual parts, instances of determinates and determinables, members of certain natural kinds and certain of their intrinsic properties, and (especially among physicalists) certain physical and mental states. Humeans maintain, however, that as per “Hume’s Dictum”, there are no necessary connections between entities that are wholly distinct;1 and in particular, no necessary causal (...) connections between such entities (even when the background conditions requisite for causation are in place). The Humean’s differential treatment appears principled, in reflecting that commonly accepted necessary connections involve constitutional relations, whereas wholly distinct entities (notably, causes and effects) do not constitute each other. I’ll argue, however, that the appearance of principle is not genuine, as per the following conditional: Constitutional→Causal: If one accepts certain constitutional necessities, one should accept certain causal necessities. This result provides needed leverage in assessing the two main frameworks in the metaphysics of science, treating natural kinds, causes, laws of nature, and the like. These frameworks differ primarily on whether Hume’s Dictum is taken as a working constraint on theorizing; and it has proved difficult for either side to criticize the other without presupposing their preferred stance on the dictum, hence talking past one another. The arguments for Constitutional→Causal are based, however, in general and independent considerations about what facts in the world might plausibly warrant our beliefs in certain constitutional necessities involving broadly scientific entities. The Humean can respond to these arguments, which reveal a deep tension in their view, at attendant costs of implausibilty and adhocery. The non-Humean framework doesn’t face any such tension between constitutional and causal necessities, however, and so in this respect comes out ahead. (shrink)

Abstract. The dissertation defends the thesis that the mind-body problem arises against the background of the elimination of the manifest physical world, and that the only satisfactory response to it is to take back that elimination and thus to dissolve the problem. Various materialist and dualist responses are shown to be inadequate. They are only different forms of ontological fundamentalism – physics fundamentalism and consciousness fundamentalism – that lead to ultimately meaningless metaphysical constructions. By contrast, on the ontologically pluralist view (...) outlined here, the fact that the entire spatiotemporal world has a physical microstructure is compatible with a naive realism with regard to both the manifest physical world and to consciousness. We only need to ascribe physical microstructures to both while identifying neither with these structures. After an introduction that identifies the elimination of the manifest physical world in modernity as the metaphysical background of the mind-body problem and describes the dilemmatic situation created by the typical reactions to it, the first chapter attempts to clarify what consciousness is. The second chapter then discusses some of the standard formulations of the so-called “puzzle” or “mystery” of consciousness. It is shown that these cannot be transformed into a genuine, answerable question. The notion that other macrophenomena can be explained much better than consciousness, perhaps even in a completely transparent way, is revealed to be an illusion, an artefact of the tacit elimination of the manifest physical world. In the third chapter, the thesis that consciousness has spatial properties is defended against various forms of skepticism. The fourth chapter begins the debate with the mind-body identity theory by discussing various positions on identity statements in the philosophy of language. This discussion leads to the conclusion that the idea of informative identity statements is meaningless. On this basis, the notion of an empirically contentful so-called “scientific identification” of consciousness phenomena with their neuronal correlates is criticized in the fifth chapter. The sixth chapter argues that it is possible to dissolve the problem of mental causation if a physiological and ultimately also a microphysical structure is ascribed to consciousness. In a concluding reflection it is explained what it means that the present suggestion amounts to a dissolution rather than a solution of the traditional mind-body problem. Zusammenfassung. In dieser Arbeit wird die These vertreten, dass das Leib-Seele- Problem vor dem Hintergrund der Elimination der manifesten physischen Welt entsteht und die einzig befriedigende Reaktion darauf nur sein kann, diese Elimination wieder rückgängig zu machen und das Problem damit aufzulösen. Materialistische und dualistische Reaktionen werden als unzulänglich erwiesen. Sie sind nur verschiedene Formen eines ontologischen Fundamentalismus – Physikfundamentalismus und Bewusstseinsfundamentalismus – der zu letztlich sinnlosen metaphysischen Konstruktionen führt. Dagegen ist nach dem hier vertretenen ontologischen Pluralismus die Tatsache, dass die gesamte raumzeitliche Welt eine physikalische Mikrostruktur hat, mit einem naiven Realismus sowohl in Bezug auf die manifeste physische Welt als auch in Bezug auf das Bewusstsein vereinbar. Wir müssen nur beiden eine physikalische Mikrostruktur zuschreiben ohne sie mit dieser zu idenfizieren. Nachdem in der Einleitung die Elimination der manifesten physischen Welt in der Neuzeit als der metaphysische Hintergrund des Leib-Seele-Problems identifiziert und die durch die typischen Reaktionen darauf entstehende dilemmatische Aus- gangssituation beschrieben worden ist, klärt das erste Kapitel, was Bewusstsein ist. Im zweiten Kapitel werden dann einige gängige Formulierungen des so genannten „Bewusstseinsrätsels“ vorgestellt. Es wird gezeigt, dass diese sich nicht in eine wirklich beantwortbare Frage transformieren lassen. Die Vorstellung, dass sich andere Makrophänomene wesentlich besser erklären lassen als das Bewusstsein, oder gar in vollständig transparenter Weise, wird als Illusion, als Artefakt der stillschweigenden Elimination der manifesten Welt erwiesen. Im dritten Kapitel wird die These, dass das Bewusstsein räumliche Eigenschaften hat, gegen verschiedene Formen der Skepsis verteidigt. Im vierten Kapitel beginnt die Auseinandersetzung mit der Identitätstheorie mit einer Diskussion sprachphilosophischer Positionen zu Identitätsaussagen, die die These begründet, dass die Vorstellung informativer Identitätsaussagen sinnlos ist. Auf dieser Grundlage wird im fünften Kapitel die Vorstellung einer empirisch gehaltvollen so genannten „wissenschaftlichen Identifikation“ von Bewusstseinsphänomenen mit ihren neuronalen Korrelaten kritisiert. Im sechsten Kapitel wird gezeigt, dass sich das Problem mentaler Verursachung auflösen lässt, wenn man Bewusstseinsphänomenen eine physiologische und letztlich auch physikalische Mikrostruktur zuschreibt. In einer Schlussbetrachtung wird erläutert, warum der Vorschlag in dieser Arbeit eine Auflösung statt einer Lösung des Leib-Seele-Problems darstellt. (shrink)

Sense experience, naïvely conceived, is a way of knowing perceptible properties: the colors, sounds, smells, flavors, and textures in our perceptual environment. So conceived, ordinary experience presents the perceiver with the essential nature of a property like Sky Blue or Middle C, such that how the property appears in experience is identical to how it essentially is. In antiquity, as today, it was controversial whether sense experience could meet the conditions for knowledge implicit in this naïve conception. Aristotle was a (...) partisan in this debate, but his position is poorly understood. This dissertation examines how Aristotle’s perceptual psychology responds to ancient challenges to the naïve conception, and so articulates his defense of perceptual knowledge. -/- Aristotle’s defense relies on an ontology of “perceptual qualities"—a core class of perceptible properties—according to which those qualities, despite having a perceiver-independent essence rooted in the physics of causation and affection, nevertheless can be present in experience as they essentially are. Chapter 1 defends this realist and objectivist reading against competing interpretations, which overlook a crucial distinction between perceptual qualities and perceptual objects. Chapter 2 presents Aristotle’s ontology as a physicalism that uncharacteristically allows for perceptual qualities to appear in experience as they essentially are. -/- This ontology informs Aristotle’s account of the psychological conditions under which perceivers actually are presented with the essence of perceptual qualities. The locus of this account is an obscure passage where Aristotle purports to show that the senses “discriminate” perceptual qualities because the senses are “mean states” (An. 2.11, 424a5–7). Chapter 3 develops a comprehensive interpretation of the sensory mean state, which Chapter 4 uses to elucidate Aristotle’s argument for sensory discrimination. Sensory discrimination turns out to be a process in which the essence of a perceptual quality comes to be present in the affection it produces in a perceiver. For Aristotle, this shows that sense perception meets a condition for knowledge that his predecessors, including Plato, thought it could not meet. For in his view, but not in theirs, sense experience shares in both the truth and the essence of the qualities it perceives. (shrink)

You see a cherry and you experience it as red. A textbook explanation for why you have this sort of experience is going to cite such things as the cherry’s chemical surface properties and the distinctive mixture wavelengths of light it is disposed to reflect. What does not show up in this explanation is the redness of the cherry. Many allege that the availability of color-free explanations of color experience somehow calls into question our beliefs about the colors of objects (...) around us. We explore how such explanations are supposed to undermine color beliefs, and in particular whether evolutionary considerations have any special role to play. (shrink)

This is the Stanford Encyclopedia of Philosophy entry on the contents of perception.

Colors are of philosophical interest for two kinds of reason. One is that colors comprise such a large and important portion of our social, personal and epistemological lives and so a philosophical account of our concepts of color is highly desirable. The second reason is that trying to fit colors into accounts of metaphysics, epistemology and science leads to philosophical problems that are intriguing and hard to resolve. Not surprisingly, these two kinds of reasons are related. The fact that colors (...) are so significant in their own right, makes more pressing the philosophical problems of fitting them into more general metaphysical and epistemological frameworks.

This paper defends and develops the structuring account of conscious attention: attention is the conscious mental process of structuring one’s stream of consciousness so that some parts of it are more central than others. In the first part of the paper, I motivate the structuring account. Drawing on a variety of resources I argue that the phenomenology of attention cannot be fully captured in terms of how the world appears to the subject, as well as against an atomistic conception of (...) attention. In the second part of the paper, I show how the structuring account can be made precise: attention causes and causally sustains phenomenal relations to hold between the parts of the stream of consciousness; most importantly the relation of one part being peripheral to another. I end by pointing out consequences for both the scientific study of attention as well as for several areas of central philosophical interest. (shrink)

A traditional conception of ontology takes existence to be its proprietary subject matter—ontology is the study of what exists (§ 1). Recently, Jonathan Schaffer has argued that ontology is better thought of rather as the study of what is basic or fundamental in reality (§ 2). My goal here is twofold. First, I want to argue that while Schaffer’s characterization is quite plausible for some ontological questions, for others it is not (§ 3). More importantly, I want to offer a (...) unified characterization of ontology that covers both existence and fundamentality questions (§§ 4-5). (shrink)

Roderick Chisholm argued that ‘look’ can be used in three different ways: epistemically, comparatively and non-comparatively. Chisholm’s non-comparative sense of ‘look’ played an important role in Frank Jackson’s argument for the sense-datum theory. The question remains..

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)

In the philosophy of perception, direct realism has come into vogue. Philosophical authors assert and assume that what their readers want, and what anyone should want, is some form of direct realism. There are disagreements over precisely what form this direct realism should take. The majority of positions in favor now offer a direct realism in which objects and their material or physical properties constitute the contents of perception, either because we have an immediate or intuitive acquaintance with those objects (...) and properties, or because our perceptual states have informational content that represents the properties of those objects (and which is not itself an object of perception and has no specifically subjective aspect). This paper considers various forms of perceptual realism, including, for purposes of comparison, the largely abandoned indirect or representative realism. After surveying the variety of perceptual realisms and considering their various commitments, I introduce some considerations concerning the phenomenology of visual space that cause trouble for most forms of direct realism. These considerations pertain to the perception of objects in the distance and, secondarily, to the perception of shapes at a slant. I argue that one of the lesser known varieties of perceptual realism, critical direct realism, can meet the challenges offered by the facts of spatial perception. (shrink)

An overview of the main positions on colour.

This paper (from 2006) is now defunct. I argue against "realist primitivism". One of my arguments is a kind of "evolutionary debunking argument". Some of the material of this was incorporated into “Can Disjunctivists Explain Our Access to the Sensible World?” and "How Does Color Experience Represent the World?".

This dissertation provides a theory of the nature of aesthetic experiences on the basis of a theory of aesthetic values. It results in the formulation of the following necessary conditions for an experience to be aesthetic: it must consist of a representation of an object and an accompanying feeling; the representation must instantiate an intrinsic value; and the feeling must be the recognition of that value and bestow it on the object. Since representations are of intrinsic value for different reasons, (...) there are different kinds of aesthetic experiences . By means of certain conceptual links, it is possible to extend this account to other aesthetic entities thus enabling the formulation of a general theory of the aesthetic in non-aesthetic terms. In particular, aesthetic values are identical with subjective dispositions to elicit aesthetic experiences under normal conditions. Accordingly, I endorse anti-realism about aesthetic values: their existence, nature and exemplification are mind-dependent, while their ascriptions to objects have genuine truth-values. I back up this account by arguing against the alternative positions that either take aesthetic values to be objective or deny the truth-aptness of their attributions. Furthermore, I put forward a relativist variant of anti-realism according to which ascriptions of different aesthetic values to a particular object are all correct, given that the aesthetic experiences involved are made under normal conditions and concern the same aesthetically nonevaluative features of that object. For there is no specifically aesthetic norm by means of which one of the faultless aesthetic experiences can be picked out as the only appropriate one. That aesthetic values nevertheless show a normative dimension is ensured by their conformity to a general account of values as capacities to satisfy, or dissatisfy, rational desires. (shrink)

This paper serves to introduce the papers from the symposium by the same title, by describing the sort of work done in philosophy of psychology conceived as a branch of the philosophy of science, distinguishing it from other discussions of psychology in philosophy, and criticizing the claims to set limits on scientific psychology in the largely psychologically uninformed literatures concerning "folk psychology' and "wide" and "narrow" content. Philosophy of psychology as philosophy of science takes seriously and analyzes the explanatory structures, (...) conceptual problems, and evidentiary practices of extant scientific psychology.
