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)

The paper discusses whether the color terms should be given an externalist semantics. In the literature on the semantics of color terms externalism is standardly taken for granted, and Twin Earth style arguments play a central role. This is notable given that few people would claim that semantic externalism applies across the board, to all types of terms. Why, then, should the color terms belong with this group of terms? I argue that the standard externalist strategies, introduced by Tyler Burge (...) and Hilary Putnam, do not apply to these terms: The color terms do not function like natural kind terms, and the idea of semantic reliance on others does not apply to them. I conclude that the externalist arguments fail and that a version of internalism, more properly called ‘individualism’,applies to the color terms. (shrink)

Recent criticisms of non-reductive accounts of color assume that the only arguments for such accounts are a priori arguments. I put forward a posteriori arguments for a non-reductive account of colors which avoids those criticisms.

The authors favor a “color realism” theory that considers colors to be physical properties residing in objects that reflect, emit, or transmit light. It is opposed to the theory that colors are sensations or visual experiences. This commentary suggests that both theories are correct, and that context usually indicates which of these dual aspects is being considered.

The reflectance types that Byrne & Hilbert identify with colors count as types only in a way that is more dependent on, and more relative to color perceivers, than their account suggests. Their account of perceptual content may be overly focused on input conditions and distal causes.

Most men and nearly all women have non-defective colour vision, as measured by standard colour tests such as those of Ishihara and Farns- worth. But people vary, according to gender, race and age in their per- formance in matching experiments. For example, when subjects are shown a screen, one half of which is lit by a mixture of red and green lights and the other by yellow or orange light, and they are asked to ad- just the mixture of lights (...) so as to make the two halves of the screen match in colour, they disagree about the location of the match. Where one male subject sees the two sides of the screen as being the same in colour, an- other female subject may see one side as a little redder or greener. And there are corresponding differences with age and race. (shrink)

As demonstrated by several example displays, color illusions challenge color realism, because they involve a one-to-many reflectance-to-color mapping. Solving this problem by differentiating between veridical and illusory colors corresponding to the same reflectance is hampered because of the lack of an appropriate criterion. However, the difference between veridical and illusory color perception can still be maintained.

Vision scientists are interested in three diverse entities: physical stimuli, neural states, and consciously perceived colors, and in the mapping rules among the three. In this worldview, the three kinds of entities have coequal status, and views that attribute color exclusively to one or another of them, such as color realism, have no appeal.

Even if spectrum inversion of various sorts is possible, spectrum inversion without a difference in representation is not. So spectrum inversion does not pose a challenge for the intentionalist thesis that, necessarily, within a given sense modality, if two experiences are alike with respect to content, they are also alike with respect to their phenomenal character. On the contrary, reflection on variants of standard cases of spectrum inversion provides a strong argument for intentionalism. Depending on one’s views about the possibility (...) of spectrum inversion, the impossibility of spectrum inversion without a difference in representation can also be used as an argument against a variety of reductive theories of mental representation. (shrink)

Representationalism is today the leading physicalist theory of the phenomenal character of perceptual experience. And Russellian representationalism, which identifies contents with extensions, is the leading iteration of that theory. If there exist phenomenally distinct experiences as of the impossible, then these would _prima facie_ serve as counterexamples to the theory. In order that they definitively serve as counterexamples, it needs to be that there is no plausible account of the experiences on which they decompose into constituent elements each of which (...) is unproblematic from the perspective of the theory. The contention of this paper is that the _stygian color experiences_, afterimage-experiences as of maximally dark, hued surfaces, of Churchland (Churchland, Philosophical Psychology 18:527–560, 2005) serve as counterexamples to Russellian representationalism.

In this commentary I argue that Byrne & Hilbert commit a number of philosophical solecisms: They beg the question of “realism,” they take the phenomenon and the theoretical model to be the same thing, and they surreptitiously substitute data sets for the life-world.

In visual science, color is usually regarded as a subjective phenomenon. The relationship between the specific color experiences that are evoked by a visual scene and the physical properties of the surfaces viewed in that scene are complex and highly dependent on spatial context. There is no simple correspondence between experienced color and a stable class of physical reflectances.

In the present article, I show that sounds are properties that are not physical in a narrow sense. First, I argue that sounds are properties using Moorean style arguments and defend this property view from various arguments against it that make use of salient disanalogies between sounds and colors. The first disanalogy is that we talk of objects making sounds but not of objects making colors. The second is that we count and quantify over sounds but not colors. The third (...) is that sounds can survive qualitative change in their auditory properties, but colors cannot survive change in their chromatic properties. Next, I provide a taxonomy of property views of sound. As the property view of sound has been so rarely discussed, many of the views available have never been articulated. My taxonomy will articulate these views and how they are related to one another. I taxonomize sounds according to three characteristics: dispositional/non-dispositional, relational/non-relational, and reductive/non-reductive. Finally, mirroring a popular argument in the color literature, I argue that physical views in the narrow sense are unable to accommodate the similarity and difference relations in which sounds essentially stand. I end replying to three objections. (shrink)

Color relationalism holds that the colors are constituted by relations to subjects. The introspective rejoinder against this view claims that it is opposed to our phenomenally-informed, pre-theoretic intuitions. The rejoinder seems to be correct about how colors appear when looking at how participants respond to an item about the metaphysical nature of color but not when looking at an item about the ascription of colors. The present article expands the properties investigated to sound and taste and inspects the mentioned asymmetry, (...) with a particular focus on the principle of charity. Using a metaphysical item, we find that color and sound are no different from shape, our control for a clearly anti-relational property. Taste, on the other hand, is no different from likability, our control for a clearly relational property. Importantly, we find that the disparity between metaphysical and ascription items is due to participants using a principle of charity to interpret disagreement cases such that both parties can be correct.

Navigating the ontology of color used to be a simple affair. There was the naive view that colors really are in objects the way they appear, and the view that they are secondary qualities to cause certain experiences in us. Today, there are myriad well-developed views but no satisfactory taxonomy of philosophical theories on color. In this article, I first examine the two newest taxonomies on offer and argue that they are inadequate. In particular, I look at Brogaard’s taxonomy and (...) then Cohen’s. One of the reasons I am displeased with Brogaard and Cohen’s taxonomies is that I find it implausible that dispositions are relational properties. I provide an argument against this way of classifying dispositions. Having learned from the vices and virtues of Brogaard and Cohens’ taxonomies, I provide what I believe is a much-enhanced way of taxonomizing philosophical views on color. My taxonomy rules out certain views, clarifies others, and shows that there is an unnoticed view worthy of consideration. (shrink)

Are the following propositions true of the colors: No object can be more than one determinable or determinate color all over at the same time (Incompatibility); the colors of objects are mind-independent (Objectivism); and most human observers usually perceive the colors of objects veridically in typical conditions (Veridicality)? One reason to think not is that the empirical literature appears to support the proposition that there is mass perceptual disagreement about the colors of objects amongst human observers in typical conditions (P-Disagreement). (...) In this article, we defend Incompatibility, Objectivism, and Veridicality by calling into question whether the empirical literature really supports P-Disagreement. (shrink)

Johnston famously argued that the colors are, more or less inclusively speaking, dispositions to cause color experiences by arguing that this view best accommodates his five proposed core beliefs about color. Since then, Campbell, Kalderon, Gert, Benbaji, and others, have all engaged with at least some of Johnston’s proposed core beliefs in one way or another. Which propositions are core beliefs is ultimately an empirical matter. We investigate whether Johnston’s proposed core beliefs are, in fact, believed by assessing the agreement/disagreement (...) of non-philosophers with them. Two experiments are run each with large sample sizes, the second designed to address criticisms of the first. We find that non-philosophers mostly agree with the proposed core beliefs, but that they agree with some more than others. (shrink)

Colour relationalism holds that the colours are constituted by relations to subjects. Anti-relationalists have claimed that this view stands in stark contrast to our phenomenally-informed, pre-theoretic intuitions. Is this claim right? Cohen and Nichols’ recent empirical study suggests not, as about half of their participants seemed to be relationalists about colour. Despite Cohen and Nichols’ study, we think that the anti-relationalist’s claim is correct. We explain why there are good reasons to suspect that Cohen and Nichols’ experimental design skewed their (...) results in favour of relationalism. We then run an improved study and find that most of our participants seem to be anti-relationalists. We find some other interesting things too. Our results suggest that the majority of ordinary people find it no less intuitive that colours are objective than that shapes are objective. We also find some evidence that when those with little philosophical training are asked about the colours of objects, their intuitions about colour and shape cases are similar, but when asked about people’s colour ascriptions, their intuitions about colour and shape cases differ. (shrink)

Relationalism is a view popularized by Cohen according to which the colors are relational properties. Cohen’s view has the unintuitive consequence that the following propositions are false: (i) no object can be more than one determinate or determinable color all over at the same time; (ii) ordinary illusion cases occur whenever the color perceptually represented conflicts, according to (i) above, with the object’s real color; and (iii) the colors we perceive obey (i). I investigate Cohen’s attempt to address these intuitive (...) propositions with which his view struggles and find it to be incompatible with how he motivates his view. (shrink)

This article is on a precise kind of color primitivism, ‘ostensivism.’ This is the view that it is in the nature of the colors that they are phenomenal, non-reductive, structural, categorical properties. First, I differentiate ostensivism from other precise forms of primitivism. Next, I examine the core belief ‘Revelation,’ and propose a revised version, which, unlike standard statements, is compatible with a yet unstated but plausible core belief: roughly, that there are interesting things to be discovered about the nature of (...) the colors. Finally, I show that ostensivism is the only view on color that can accommodate both proposed core beliefs. (shrink)

Intrapersonal variation due to color contrast effects has been used to argue against the following intuitive propositions about the colors: No object can be more than one determinable or determinate color of the same grade all over at the same time ; external objects are actually colored ; and the colors of objects are mind-independent. In this article, I provide a defense of Incompatibility, Realism, and Objectivism from intrapersonal variation arguments that rely on color contrast effects. I provide a novel, (...) ecumenical response to such arguments according to which typical variants are right, and which respects Incompatibility, Realism, and Objectivism, using the thesis that the colors of objects depend on the colors of objects in their surrounds.

You're not as clever as you think you are. Nor for that matter are you as good a driver, teacher or romantic partner as you take yourself to be and, as if that wasn't bad enough, you are also considerably less popular than you have hitherto believed. Finally – and crucially for the argument of this paper – I contend that your abilities as an aesthetic judge are considerably less impressive than you take them to be. To avoid descending into (...) name calling it's worth pointing out that such claims apply to the vast majority of people – myself, somewhat paradoxically, included. (shrink)

Common everyday materials such as textiles, foodstuffs, soil or skin can have complex, mutable and varied appearances. Under typical viewing conditions, most observers can visually recognize materials effortlessly, and determine many of their properties without touching them. Visual material perception raises many fascinating questions for vision researchers, neuroscientists and philosophers, yet has received little attention compared to the perception of color or shape. Here we discuss some of the challenges that material perception raises and argue that further philosophical thought should (...) be directed to how we see materials. (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)

Color vision provides accurate measures of the phase and intensity of daylight, and also a means of discriminating between objects. Neither property implies that objects are colored.

I argue that Byrne & Hilbert (B&H) have not answered Hardin's objection to physicalism about color concerning the unitary-binary structure of the colors for two reasons. First, their account of unitary-binary structure seems unsatisfactory. Second, pace B&H, there are no physicalistically acceptable candidates to be the hue-magnitudes. I conclude with a question about the justification of physicalism about color.

In this paper, I compare various theories of perception in relation to the question of the epistemological and ontological status of the qualities that appear in perceptual experience. I group these theories into two main views: quality externalism and quality internalism, and I highlight their contrasting problems in accounting for phenomena such as perceptual relativity, illusions and hallucinations. Then, I propose an alternative view, which I call qualitative relationism and which conceives of the subject and the object of perceptual experience (...) as essentially related to one another in a process of co-constitution out of fundamental qualities. I lend support to this view by drawing on Husserl’s genetic phenomenology, which I complement with a form of neutral monism. I argue that the investigation of the temporal structure of perceptual experience leads us to find at its heart a qualitative process that is more fundamental than the two relata of perception and that gives rise to them. Then, I extend this account of perception into a general theory of intentionality and experience and I develop its implications into a neutral monist metaphysics. (shrink)

In this paper, I compare the original version of the enactive view—autopoietic enactivism—with Husserl’s phenomenology, regarding the issue of the relationship between consciousness and nature. I refer to this issue as the “problem of naturalism.” I show how the idea of the co-determination of subject and object of cognition, which is at the heart of autopoietic enactivism, is close to the phenomenological form of correlationism. However, I argue that there is a tension between an epistemological reading of the subject-object correlation (...) that renounces to search for its metaphysical ground, and the enactivist focus on the biological basis of cognition, which seems to imply a view of nature as the metaphysical ground of the conscious mind. A similar problem arises in Husserl’s phenomenology in the contrast between the idea of the fundamental subject-object correlation, the concept of nature as a correlate of transcendental constitution, and the investigation of the corporeal and material grounding of consciousness. I find a way out of this problem by drawing on the distinction between static and genetic phenomenology. I argue that the investigation of the temporality of experience in genetic phenomenology leads us to investigate the metaphysical ground of the subject-object correlation, understood dynamically as co-constitution and co-origination. Then I propose to complement phenomenology and enactivism with a form of neutral monism, which conceives of the co-constitution of subject and object as grounded in a flow of fundamental, pre-phenomenal qualities.

Visual percepts are called veridical when a “real” object can be identified as their cause, and illusions otherwise. The perceived position and color of a flashed object may be called veridical or illusory depending on which viewpoint one adopts. Since “reality” is assumed to be fixed (independent of viewpoint) in the definition of veridicality (or illusion), this suggests that “perceived” position and color are not properties of “real” objects.

Researchers working on children's moral understanding maintain that the child's capacity to distinguish morality from convention shows that children regard moral violations as objectively wrong. Education in the moral domain. Cambridge: Cambridge University Press). However, one traditional way to cast the issue of objectivism is to focus not on conventionality, but on whether moral properties depend on our responses, as with properties like icky and fun. This paper argues that the moral/conventional task is inadequate for assessing whether children regard moral (...) properties as response-dependent. Unfortunately, children's understanding of response-dependent properties has been neglected in recent research. Two experiments are reported showing that children are more likely to treat properties like fun and icky as response-dependent than moral properties like good and bad. Hence, this helps support the claim that children are moral objectivists. (shrink)

While color realism is endorsed, Byrne & Hilbert's (B&H's) case for it stretches the notion of “physical property” beyond acceptable bounds. It is argued that a satisfactory account of color should do much more to respond to antirealist intuitions that flow from the specificity of color experience, and a pointer to an approach that does so is provided.

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)

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.

According to anti-atomism, we represent color properties (e.g., red) in virtue of representing color relations (e.g., redder than). I motivate anti-atomism with a puzzle involving a series of pairwise indistinguishable chips. I then develop two versions of anti-atomism.

The analogy between gustatory taste and critical or aesthetic taste plays a recurring role in the history of aesthetics. Our interest in this article is in a particular way in which gustatory judgments are frequently thought to be analogous to critical judgments. It appears obvious to many that to know how a particular object tastes we must have tasted it for ourselves; the proof of the pudding, we are all told, is in the eating. And it has seemed just as (...) obvious to many philosophers that aesthetic judgment requires first-person experience. In this article we argue that, despite its initial appeal, the claim that gustatory and critical judgments are analogous in this way is mistaken. The two sorts of judgments are, as a matter of fact, similar in their epistemology, but earlier theorists have got things entirely backward—neither gustatory judgment nor aesthetic judgment requires first-hand acquaintance with their objects. Our particular focus in this article is on arguing that first-person experience is not required to know how an item of food or drink tastes. In fact, there are a wide variety of ways in which we can acquire this knowledge. (shrink)

“The problem of color realism” as defined in the first section of the target article, is crucial to the argument laid out by Byrne & Hilbert. They claim that the problem of color realism “does not concern, at least in the first instance, color language or color concepts” (sect. 1.1). I argue that this claim is misconceived and that a different characterisation of the problem, and some of their preliminary assumptions makes their positive proposal less appealing.

Byrne & Hilbert conceive of color perception as the representation of a physical property “out there.” In our view, their approach does not only have various internal problems, but is also apt to becloud both the intricate and still poorly understood role that “ color ” plays within perceptual architecture, and the complex coupling to the “external world” of the perceptual system as an entirety. We propose an alternative perspective, which avoids B&H's misleading dichotomy between a purely subjective and a (...) realist conception of “ color.”. (shrink)

Byrne & Hilbert are right that it might be an objective fact that a particular tomato is unique red, but wrong that it cannot simultaneously be yellowish-red (not only objectively, but from somebody else's point of view). Sensory categorization varies among organisms, slightly among conspecifics, and sharply across taxa. There is no question of truth or falsity concerning choice of categories, only of utility and disutility. The appropriate framework for color categories is Nominalism and Pluralistic Realism.

Byrne & Hilbert propose that color can be identified with explicit properties of physical surfaces. I argue that this claim must be qualified to take into account constraints needed to make recovery of surface color information possible. When these constraints are satisfied, then a biological visual system can establish a correspondence between perceived surface color and specific surface properties.

For all animals, color is an indicator of the substance and state of objects, for which purpose reflectance is just one among many relevant optical properties. This broader meaning of color is confirmed by linguistic evidence. Rather than reducing color to a simple physical property, it is more realistic to embrace its full phenomenology.

Revelation, the thesis that the full intrinsic nature of colors is revealed to us by color experiences, is false in Byrne & Hilbert's (B&H's) view, but in an interesting and nonobvious way. I show what would make Revelation true, given B&H's account of colors, and then show why that situation fails to obtain, and why that is interesting.

Reflectance and spectral power functions are poor predictors of color experiences. Only in completely relativized conditions (single observer, non-metameric set of stimuli, and single set of viewing conditions) is the relationship close. Variation in reflectance of Munsell chips experienced by color-normal observers as having a unique green hue encompasses approximately sixty percent of the complete range of hues falling under the category “green”; and in recent determinations of unique hues, ranges of yellow and green as well as green and blue (...) unique hues overlap.

A critical review of Paul Boghossian's Fear of Knowledge. I argue that the central argument against epistemic relativism fails and that even if the arguments of Fear of Knowledge worked perfectly on their own terms, Fear of Knowledge would fail to persuade the relativistically inclined.

Colors are sensible qualities. They are qualities that objects are perceived to have. Thus, when Norm, a normal perceiver, perceives a blue bead, the bead is perceived have a certain quality, perceived blueness. `Quality', here, is no mere synonym for property; rather, a quality is a kind of property a qualitative, as opposed to quan• titative, property. (The quantitative is a way of contrasting with the qualitative perhaps not the only way.).

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.

We make three points. First, the concept of productance value that the authors propose in their defense of color physicalism fails to do the work for which it is intended. Second, the authors fail to offer an adequate physicalist account of what they call the hue-magnitudes. Third, their answer to the problem of individual differences faces serious difficulties.

Attempts to account for the phenomenal character of perceptual experiences have so far largely focused on their sensory aspects. The first aim of this article is to support the claim that phenomenal character has another, significant, aspect—the phenomenal realm is suffused with valence. What it’s like to undergo perceptual experiences—from pains to supposedly “neutral” visual experiences—standardly feels good or bad to some degree. The second aim is to argue, by appealing to theoretical and empirical considerations pertaining to the phenomenon of (...) valence-variance, that perceptual valence cannot be accounted for by extending the prevalent representationalist account of phenomenal character. Thus, a revision in the understanding of phenomenal character is called for. Finally, the phenomenon of valence-variance serves to make some headway toward defending a new Attitudinal-Representational Theory of perceptual valence, according to which perceptual valence is constituted by first-order conative attitudes directed toward the representational objects of experiences.

Those who identify colours with physical properties need to say how the content of colour experiences relate to their favoured identifications. This is because it is not plausible to hold that colour experiences represent things as having the physical properties in question. I sketch how physical realists about colour might tackle this item of unfinished business.
