I propose that accounts of emotional expression can be divided into primary and secondary quality accounts. Primary quality accounts of expression take behaviour to express emotion only if certain perceiver-independent facts about the behaviour or behaving subject obtain. I argue that views of this kind get the extension of expression wrong. I argue instead that behaviour expresses emotion just in case it is disposed to appear to express emotion to standard observers under standard conditions.

How all philosophical explanations of human consciousness and the fundamental structure of the cosmos are bizarre—and why that’s a good thing Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it’s hard to say. In The Weirdness of the World, Schwitzgebel argues that the answers to these fundamental (...) questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird. Philosophy, he proposes, can aim to open—to reveal possibilities we had not previously appreciated—or to close, to narrow down to the one correct theory of the phenomenon in question. Schwitzgebel argues for a philosophy that opens. According to Schwitzgebel’s “Universal Bizarreness” thesis, every possible theory of the relation of mind and cosmos defies common sense. According to his complementary “Universal Dubiety” thesis, no general theory of the relationship between mind and cosmos compels rational belief. Might the United States be a conscious organism—a conscious group mind with approximately the intelligence of a rabbit? Might virtually every action we perform cause virtually every possible type of future event, echoing down through the infinite future of an infinite universe? What, if anything, is it like to be a garden snail? Schwitzgebel makes a persuasive case for the thrill of considering the most bizarre philosophical possibilities. (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.

I advance an account of quantitative character, a species of phenomenal character that presents as an intensity (cf. a quality) and includes experience dimensions such as loudness, pain intensity, and visual pop-out. I employ psychological and neuroscientific evidence to demonstrate that quantitative characters are best explained by attentional processing, and hence that they do not represent external qualities. Nonetheless, the proposed account of quantitative character is conceived as a compliment to the reductive intentionalist strategy toward qualitative states; I argue that (...) an account of perceptual experience that combines a tracking account of qualitative character with my functionalist proposal for quantitative character permits replies to some notoriously difficult problems for tracking representationalism without sacrificing its chief virtues.

Many philosophers of physics think that physical rates of change, like velocity or acceleration in classical physics, are extrinsic. Many philosophers of mind think that phenomenal properties, which characterize what it’s like to be an agent at a time, are intrinsic. I will argue that these two views can’t both be true. Given that these two views are in tension, we face an explanatory challenge. Why should there be any interesting connection between these physical quantities and consciousness in the first (...) place? In a speculative spirit, I close by developing a panpsychist view which promises to explain this connection in a particularly satisfying way. (shrink)

It is common for an object to present different colour appearances to different perceivers, even when the perceivers and viewing conditions are normal. For example, a Munsell chip might look unique green to you and yellowish green to me in normal viewing conditions. In such cases, there are three possibilities. Ecumenism: both experiences are veridical. Nihilism: both experiences are non-veridical. Inegalitarianism: one experience is veridical and the other is non-veridical. Perhaps the most important objection to inegalitarianism is the ignorance objection, (...) according to which inegalitarianism should be rejected because it is committed to the existence of unknowable colour facts. The goal of this paper is to show that ecumenists are also committed to unknowable colour facts. More specifically, I argue that, with the exception of colour eliminativism, all major philosophical theories of colour are committed to unknowable colour facts. (shrink)

I defend a how-possibly argument for Kantian (or Kant*-ian) transcendental idealism, drawing on concepts from David Chalmers, Nick Bostrom, and the cyberpunk subgenre of science fiction. If we are artificial intelligences living in a virtual reality instantiated on a giant computer, then the fundamental structure of reality might be very different than we suppose. Indeed, since computation does not require spatial properties, spatiality might not be a feature of things as they are in themselves but instead only the way that (...) things necessarily appear to us. It might seem unlikely that we are living in a virtual reality instantiated on a non-spatial computer. However, understanding this possibility can help us appreciate the merits of transcendental idealism in general, as well as transcendental idealism’s underappreciated skeptical consequences.

The focus of this paper is introspection of phenomenal states, i.e. the distinctively first-personal method through which one can form beliefs about the phenomenology of one’s current conscious mental states. I argue that two different kinds of phenomenal state introspection should be distinguished: one which involves recognizing and classifying the introspected phenomenal state as an instance of a certain experience type, and another which does not involve such classification. Whereas the former is potentially judgment-like, the latter is not. I call (...) them, respectively, reflective introspection and primitive introspection. The purpose of this paper is to argue that primitive introspection is a psychologically real phenomenon. I first introduce the distinction and provide some preliminary motivation to accept it (§1). After some set-up considerations (§2), I present my central argument for the existence of a non-classificatory kind of introspective state (§3), what I call the ‘argument from phenomenal-concept acquisition’. Finally, I briefly present some reasons why my distinction may be important for various philosophical debates (§4). (shrink)

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending a (...) structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

Dispositional theories of colour have been attacked by McGinn and others on the ground that ‘Colours do not look like dispositions’. Langsam has argued that on the contrary they do, in ‘Why Colours Do Look Like Dispositions’, The Philosophical Quarterly, 50 , pp. 68–75. I make three claims. First, neither side has made its case. Secondly, it is true, at least on one interpretation, that colours do not look like dispositions. Thirdly, this does not show that dispositionalism about colours is (...) false. (shrink)

In this paper I reply to two sets of criticisms—a first from Joshua Gert, and a second from Keith Allen—of the relationalist view of color developed and defended in my book, The Red and the Real: An Essay on Color Ontology.

Nat Hansen builds a new argument for subjectivism about the semantics of color language, based on a potential kind of intersubjective disagreements about comparative color statements. In reply, I note that the disagreements of this kind are merely hypothetical, probably few if actual, and not evidently relevant as test cases for a semantic theory. Furthermore, even if they turned out to be actual and semantically relevant, they would be intuitively unusable by the subjectivist.

Arguably one of the most fundamental phase shifts that occurred in the intellectual history of Western culture involved the ontological reduction of secondary qualities to primary qualities. To say the least, this reduction worked to undermine the foundations undergirding Aristotelian thought in support of a scientific view of the world based strictly on an examination of the real—primary— qualities of things. In this essay, I identify the so-called “Causal Argument” for a reductive view of secondary qualities and seek to deflect (...) this challenge by deriving some plausible consequences that support a non-reductive view of secondary qualities from an Aristotelian view (via the philosophical commentary of Thomas Aquinas). Specifically, my argument has two facets. First, I show that Aristotle’s view both implies recognition of the extramental existence of secondary qualities and is a prima facia natural view to take regarding the ontology of secondary qualities. Second, I show that the Causal Argument, which is thought to undermine a natural view of secondary qualities as real things, loses its bite when one examines perception in light the ontological relationship among the categories of quality, quantity and substance.

I will develop a new problem for almost all realist theories of colour. The problem involves fluctuations in our colour experiences that are due to visual noise rather than changes in the objects we are looking at.

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.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

Color relationalism is the view that colors are constituted in terms of relations between subjects and objects. The most historically important form of color relationalism is the classic dispositionalist view according to which, for example red is the disposition to look red to standard observers in standard conditions (mutatis mutandis for other colors).1 However, it has become increasingly apparent in recent years that a commitment to the relationality of colors bears interest that goes beyond dispositionalism (Cohen, 2004; Matthen, 1999, 2001, (...) 2005; Thompson, 1995). Accordingly, it is an important project for those interested in the metaphysics of color to sort through and assess different forms of color relationalism. There is, however, a powerful and general cluster of objections that has been thought by many to amount to a decisive refutation of any and all forms of color relationalism. Although this idea has been developed in a number of ways, the basic thought is that relationalism — qua theory of color — is at odds with the manifest evidence of color phenomenology, and that this clash between theory and data should be resolved by giving up the theory.

Philosophers of mind have distinguished (and sometimes conflated) various qualities. This article tries to sort things out.

We examine the pros and cons of color realism, exposing some desiderata on a theory of color: the theory should render colors as scientifically legitimate and correctly individuated, and it should explain how we have veridical color experiences. We then show that these desiderata can by met by treating colors as properties of the special sciences. According to our view, some of the major as properties of the special sciences. According to our view, some of the major disputes in the (...) literature about color -- anti-realism versus dispositionalism versus reductionism -- are not well-founded at this stage of scientific inquiry. Our account of color is designed to be of use in the sciences and as such is driven largely by considerations of what the various sciences need in order to proceed appropriately. We argue that a scientific theory of colors need not regard colors as anything more than high-level statistical constructs built out of correlations between color experiences and other phenomena. (shrink)

A traditional explanation that dates back to Aristotle is that we access color in one perceptual modality only, whereas shape we perceive via two different modalities: visual and tactile. Two independent modalities make possible a verification of our percepts which is not possible for qualities accessed in one modality only.

If you stare for a period of time at a scene which contains movement in one direction, and then turn your attention to an object in a scene which contains no movement, this object will appear to move in the opposite direction to that of the original movement. The effect can be easily achieved by attaching a piece of paper with a spiral drawn on it to the spinning turntable of a record player, and then turning the turntable off while (...) continuing to look at the spiral (see Frisby 1979, pp. 100-101 for a detailed descrip- tion of how to bring this about). But the illusion of movement can also occur when looking at a waterfall, for instance, and turning one's attention away from the waterfall to a stationary object such as a stone; hence its name - the 'Waterfall Illusion'.

This paper argues for the reality of qualia as aspects of phenomenal experience. The argument focuses on color vision and develops a dispositionalist, subjectivist account of what it is for an object to be colored. I consider objections to dispositionalism on epistemological, metaphysical, and 'ordinary' grounds. I distinguish my representative realism from sense-data theories and from recent 'representational' or 'intentional' theories, and I argue that there is no good reason to adopt a physicalist stance that denies the reality of qualia (...) as phenomenally available intentional contents in Brentano's original sense of 'intentionality'. (shrink)

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

Adverbialism is the view that to have a conscious perceptual experience is to be consciously experiencing in a certain way, and that this way is not to be understood in relational or representational terms. We might compare what it is for a conscious being to be experiencing in a certain way with what it is for a string to be vibrating in a certain way. This paper makes a new case for adverbialism by appealing to the fact that we can (...) pick out ways of experiencing by treating them as information-bearing signals. In both presenting and defending the view, it will be crucial that information is not the same as representational content, but can still concern objects and the properties of those objects. The resulting information-theoretic adverbialism can answer or deflect the most influential objections to adverbialism. (shrink)

Some sounds have pitch, some do not. A tuba’s notes are lower pitched than a flute’s, but the fuzz from an untuned radio has no discernible pitch. Pitch is an attribute in virtue of which sounds that possess it can be ordered from “low” to “high”. Given how audition works, physics has taught us that frequency determines what pitch a sound auditorily appears to have.

In The Quest for Reality: Subjectivism and the Metaphysics of Colour [Stroud, 2000], Barry Stroud carries out an ambitious attack on various forms of irrealism and subjectivism about color. The views he targets - those that would deny a place in objective reality to the colors - have a venerable history in philosophy. Versions of them have been defended by Galileo, Descartes, Boyle, Locke, and Hume; more recently, forms of these positions have been articulated by Williams, Smart, Mackie, Ryle, and (...) Hardin, among others. Stroud's aim is to argue not only that these writers fail to make their cases, but that no conceivable argument could ever convince us that colors are not a part of objective reality. (shrink)

You may speak of a chain, or if you please, a net. An analogy is of little aid. Each cause brings about future events. Without each the future would not be the same. Each is proximate in the sense it is essential. But that is not what we mean by the word. Nor on the other hand do we mean sole cause. There is no such thing.

Are colors relational or non-relational properties of their bearers? Is red a property that is instantiated by all and only the objects with a certain intrinsic (/non-relational) nature? Or does an object with a particular intrinsic (/non-relational) nature count as red only in virtue of standing in certain relations - for example, only when it looks a certain way to a certain perceiver, or only in certain circumstances of observation? In this paper I shall argue for the view that color (...) properties are relational (henceforth, relationalism), and against the view that colors are not relational (henceforth, anti- or non-relationalism).

Qualia inversion thought experiments are ubiquitous in contemporary philosophy of mind. The most popular kind is one or another variant of Locke's hypothetical case of.

The aim of the study is to clarify the aesthetic concept of color perception from the phenomenological reasoning of Edmund Husserl. Today, the orientation diagram of the field of phenomenological research is formed in various zones: from theological to naturalistic. In which of these zones the structures of the phenomenological analysis of color are located is not an easy question. The coloristic region is constituted according to the degree of consciousness, including aesthetic consciousness. It is extremely difficult to meet with (...) the phenomenon of color, if only because its obviousness is fulfilled only by the fervor of the contemplative consciousness with its aesthetic pathos, a consciousness that distinguishes between, as it were, the reality of transcendent color and the aesthetic "continent of givens". We are talking, as Husserl would say, about the halo of consciousness, referring to the essence of perception performed in the mode of turning to the beauty of color. For the first time, approaches to the study of such a complex phenomenological topic as the description of a coloristic attitude, the eidetics of color experiences in Husserl's philosophy are outlined, the significance of its development for the comprehension of aesthetic and artistic consciousness is revealed. The main conclusions of the study are related to the philosophical interpretation of the idea of color as included in phenomenology in the experience of philosophical surprise, which turns into the acquisition of the essence of "phenomenological color" in general, and in aesthetics it is directly correlated with the appearance of its structures on the horizon of the harmonic synthesis of acts of perceptual performance in the imagination, "primordial giving visions" of color, with the creation of a picture coloristic impressions as cognitive emotions, reduced pure color perception, with an understanding of how art makes the very conditions of color visibility obvious, how its artistic synthesis is made, in the structure of which correlation analysis can see an analogue of a priori empiricism – this fundamental characteristic of purely Husserl synthesis and method revealed in domestic studies.

It is plausible to think that some animals perceive the world as coloreddifferently from the way humans perceive it. I argue that the best way ofaccommodating this fact is to adopt perceiver-relativism, the view that colorpredicates express relations between objects and types of perceivers.Perceiver-relativism makes no claim as to the identity of color properties;it is compatible with both physicalism and dispositionalism. I arguehowever for a response-dependence version of it according to which an object counts as red (for a type of (...) perceiver) iff it standardly looks red to normal perceivers (of that type). Finally, I develop a notion of minimal realism on which this account counts as realist despite its subjectivist elements, in that it is committed to the objectivityof truth. (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...

In this paper I propose and defend an account of color that I call color functionalism. I argue that functionalism is a non-traditional species of primary quality theory, and that it accommodates our intuitions about color and the facts of color science better than more widely discussed alternatives.

According to colour irrealism, material objects do not have colour; they only appear to have colour. The appeal of this view, prominent among philosophers and scientists alike, stems in large part from the conviction that scientific explanations of colour facts do not ascribe colour to material objects. To explain why objects appear to have colour, for instance, we need only appeal to surface reflectance properties, properties of light, the neurophysiology of observers, etc. Typically attending colour irrealism is the error theory (...) of ordinary colour judgement: ordinary judgements in which colour is ascribed to a material object are, strictly speaking, false. In this paper, I claim that colour irrealists who endorse the error theory cannot explain how we acquire colour concepts (yellow, green, etc.), concepts they must acknowledge we do possess. Our basic colour concepts, I argue, could not be phenomenal concepts that we acquire by attending to the colour properties of our experience. And, I explain, all other plausible explanations render colour concepts such that our ordinary colour judgements involving them are often true. Given the explanatory considerations upon which the irrealist's position is based, this is a severe problem for colour irrealism. (shrink)

Scientists are often bemused by the efforts of philosophers essaying a theory of colour: colour science sports a huge array of facts and theories, and it is unclear to its practitioners what philosophy can or is trying to contribute. Equally, philosophers tend to be puzzled about how they can fit colour science into their investigations without compromising their own disciplinary identity: philosophy is supposed to be an a priori investigation; philosophers do not work in psychophysics labs – not in their (...) professional capacity, anyway.These inter-disciplinary barriers arise out of misunderstanding. Philosophers should not so much attempt to contribute to empirical theories of colour, as to formulate philosophical theories of colour. Philosophy is concerned with appearance and reality, object and property, function and representation, and other such fundamental categories of ontology and epistemology. Philosophical theories attempt to fit colour into these categories; such theories do not compete with colour science. However, fitting colour into philosophical theories means dealing with colour as it really is – and one cannot know what it is without consulting the psychologists. That is why philosophers need an up-to-date understanding of psychological theories of colour. (shrink)

Sentimentalists believe that values are crucially dependent on emotions. Epistemic sentimentalists subscribe to what I call the final-court-of-appeal view: emotional experience is ultimately necessary and can be sufficient for the justification of evaluative beliefs. This paper rejects this view defending a moderate version of rationalism that steers clear of the excesses of both “Stoic” rationalism and epistemic sentimentalism. We should grant that emotions play a significant epistemic role in justifying evaluations. At the same time, evaluative justification is not uniquely or (...) especially dependent on emotions. The anti-sentimentalist argument developed in this paper is based on the indeterminacy thesis. The thesis states that the evaluative properties picked out by our emotional responses are too indeterminate to play a central role in our evaluative practices. I argue that while the indeterminacy thesis undermines the final-court-of-appeal view it supports the claim that emotional responses can provide prima facie justification for evaluative beliefs.

«Secondo convenzione è il colore, secondo convenzione è il dolce, secondo convenzione l’amaro, mentre veri sono gli atomi e il vuoto». A partire da questo frammento di Democrito, la filosofia si è contrapposta all’idea del senso comune secondo cui i colori sono proprietà degli oggetti.

Studies show that there are widespread intrasubjective and intersubjective color variations among normal perceivers. These variations have serious ramifications in the debate about the nature and ontology of color. It is typical to think of the debate about color as a dispute between objectivists and subjectivists. Objectivists hold that colors are perceiver-independent physical properties of objects while subjectivists hold that they are either projections onto external objects or dispositions objects have to look colored. I argue that individual color variations present (...) difficulties, albeit not the same kind, for both objectivism and subjectivism. Lastly, I propose an alternative account that handles such variations nicely. (shrink)

Frank Jackson’s knowledge argument (KA) aims to prove, by means of a thought experiment concerning the hypothetical scientist Mary, that conscious experiences have non-physical properties, called qualia. Mary has complete scientific knowledge of colours and colour vision without having had any colour experience. The central intuition in the KA is that, by seeing colours, Mary will learn what it is like to have colour experiences. Therefore, her scientific knowledge is incomplete, and conscious experiences have qualia. In this paper I consider (...) an objection to the KA raised by Daniel Dennett. He maintains that the KA is vitiated by Jackson’s account of Mary’s scientific knowledge. While endorsing this criticism, I will defend the plausibility and relevance of the type of strategy involved in the KA by offering an account of Mary’s scientific knowledge. This account involves formulating a reasonable and not immediately false version of the physicalist thesis with regard to colour experiences. Whether this version of the KA is successful against this type of physicalism is not investigated here. (shrink)

An adequate ontology of color must face the empirical facts about per- ceptual variation. In this paper I begin by reviewing a range of data about perceptual variation, and showing how they tell against color physicalism and motivate color relationalism. Next I consider a series of objections to the argument from perceptual variation, and argue that they are un- persuasive. My conclusion will be that the argument remains a powerful obstacle for color physicalism, and a powerful reason to believe in (...) color relationalism instead. (shrink)

Whether or not one endorses realism about colour, it is very tempting to regard realism about determinable colours such as green and yellow as standing or falling together with realism about determinate colours such as unique green or green31. Indeed some of the most prominent representatives of both sides of the colour realism debate explicitly endorse the idea that these two kinds of realism are so linked. Against such theorists, the present paper argues that one can be a realist about (...) the determinable colours of objects, and thus hold that most of the colour ascriptions made by competent speakers are literally true, while denying that there are any positive facts of the matter as to the determinate colours of objects. The result is a realistic colour realism that can certify most of our everyday colour ascriptions as literally correct, while acknowledging the data regarding individual variation. (shrink)

The central aim of this paper is to argue that the main motivation for endorsing colour relativism – namely, the occurrence of so-called standard variation phenomena – constitutes, in the end, a problem for the view itself which is not significantly smaller than the problem these phenomena constitute for most of the view’s competitors. Section 1 provides a brief characterization of the relativist position in question. In Section 2, I provide a prima facie case for colour relativism in the light (...) of the occurrence of standard variation phenomena, and I argue that a certain version of the view can be defended against certain objections that have been raised against colour relativism. Section 3 provides an argument for the central claim of this paper, that is, an argument to the conclusion that standard variation phenomena do, in the end, not at all favour colour relativism over its main competitors. Finally, in Section 4, I suggest and tentatively defend a hitherto neglected account of the meaning of colour terms that accommodates the phenomena in question. (shrink)

I offer a new objectivist theory of the contents of color language and color experience, intended especially as an account of what normal intersubjective variation in color perception and classification shows about those contents. First I explain an abstract account of the contents of color and other gradable adjectives; on the account, these contents are certain objective properties constituted in part by contextually intended standards of application, which are in turn values in the dimensions of variation associated with the adjectives. (...) Then I propose an explanation of normal variations in linguistic color classification; these are postulated to be effects of differences in intended standards for the color adjectives appearing in the classifying predicates. Next, I consider a potential objection to this explanation, based on the suggestion that contextual content should be more accessible than the explanation predicts. In reply, I point out that contextual content is occasionally opaque to unsophisticated reflection. Finally, I present a companion account of the contents of color experiences on which these represent an object as lying on certain salient intervals in the chromatic dimensions, and I show how the account accommodates intersubjective variation in color perception.

The analogy between colors and values is strongly interlinked with the idea that these properties are by nature dispositions or response-dependent properties. Indeed, that colors are essentially visible, and values are inherently motivational, cries out for a dispositional or a response-dependent account. Recently, Primitivism has challenged the viability of the dispositional account of colors, taking the apple, for instance, to be “gloriously, perfectly, and primitively red.” Unsurprisingly, the attack on the dispositional account of colors has found a moral analogue in (...) the view that values are sui generis irreducibly primitive properties. The question this article addresses is whether given Primitivism the analogy between colors and values is preserved; or in other words, whether Primitivism breaks the bond between the dispositional account and the analogy between colors and values.

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 discuss two forms of the thesis that to have a sensation is to token a sentence in a language of thought-what I call, following Georges Rey, the sensational sentences thesis. One form of the thesis is a version of standard functionalism, while the other is a version of the increasingly popular thesis that for a sensation to have qualia is for it to have a certain kind of intentional content-that is, intentionalism. I defend the basic idea behind the sensational (...) sentences thesis, and argue that the intentionalist version is either false or collapses into the standard functionalist thesis. (shrink)
