I address the question of whether differences in color terminology cause differences in color experience in speakers of different languages. If linguistic representations directly affect color experience, then this is a case of what I call the linguistic penetrability of perception, which is a particular case of cognitive penetrability. I start with some general considerations about cognitive penetration and its alleged occurrence in the memory color effect. I then apply similar considerations to the interpretation (...) of empirical studies of color perception in speakers of different languages. I argue that findings such as differences in categorical perception in speakers of different languages do not show that language affects color experience. They therefore do not support the claim that color experience is linguistically penetrable. But even if we grant that color experience is different in speakers of different languages, I argue that this might still not be a case of linguistic penetration. Finally, I consider some epistemological consequences of the assumption that speakers of different languages have different color experiences. (shrink)

Blindsight, the ability to blindly discriminate wavelength and other aspects of stimuli in a blind field, sometimes occurs in people with lesions to striate (V1) cortex. There is currently no consensus on whether qualitative color information of the sort that is normally computed by double opponent cells in striate cortex is indeed computed in blindsight but doesn’t reach awareness, perhaps owing to abnormal neuron responsiveness in striate or extra-striate cortical areas, or is not computed at all. The existence of (...) primesight, the experience of colored afterimages in blindsight, has been taken to suggest that qualitative color information is computed either in pre-striate or striate cortical areas but is not broadcast to working memory. I argue here that a recent study in which color phosphenes were induced in a blindsighter using bilateral transcranial magnetic stimulation indicates that computations necessary for conscious color vision are lost in blindsight. Owing to this loss, the neural responsiveness in extrastriate cortical areas is abnormal and hence is unable to give rise to color awareness. Blindsight is thus degraded vision in which the computations necessary for conscious color vision have been lost. (shrink)

This chapter explores the evidence for the existence of such new colour experiences and what their philosophical ramifications would be. I first define the notion of ‘novel colours’ and discuss why I think that this is the best name for such colours, rather than the numerous other names that they have sometimes been given in the literature. I then introduce the evidence and arguments for thinking that experiences as of novel colours exist, along with objections that people have had to (...) that evidence and to those arguments. To do so, I outline some facts about ordinary, non-novel colours before considering whether experiences as of novel colours, exist. Then I discuss the potentially significant ramifications the existence of novel colour experiences would have for theories of the metaphysics of colour, theories of the nature of colour experience, and for theories of the nature of perception more generally.

Many favor representationalism about color experience. To a first approximation, this view holds that experiencing is like believing. In particular, like believing, experiencing is a matter of representing the world to be a certain way. Once you view color experience along these lines, you face a big question: do our color experiences represent the world as it really is? For instance, suppose you see a tomato. Representationalists claim that having an experience with this sensory (...) character is necessarily connected with representing a distinctive quality as pervading a round area out there in external space. Let us call it “sensible redness” to highlight the fact that the representation of this property is necessarily connected with the sensory character of the experience. Is this property, sensible redness, really co-instantiated with roundness out there in the space before you? (shrink)

Is color experience cognitively penetrable? Some philosophers have recently argued that it is. In this paper, we take issue with the claim that color experience is cognitively penetrable. We argue that the notion of cognitive penetration that has recently dominated the literature is flawed since it fails to distinguish between the modulation of perceptual content by non-perceptual principles and genuine cognitive penetration. We use this distinction to show that studies suggesting that color experience can (...) be modulated by factors of the cognitive system do not establish that color experience is cognitively penetrable. Additionally, we argue that even if color experience turns out to be modulated by color-related beliefs and knowledge beyond non-perceptual principles, it does not follow that color experience is cognitively penetrable since the experiences of determinate hues involve post-perceptual processes. We conclude with a brief discussion of the implications that these ideas may have on debates in philosophy. (shrink)

In this Handbook entry, I review how colour similarity spaces are constructed, first for physical sources of colour and secondly for colour as it is perceptually experienced. The unique hues are features of one of the latter constructions, due initially to Hering and formalized in the Swedish Natural Colour System. I review the evidence for a physiological basis for the unique hues. Finally, I argue that Tye's realist approach to the unique hues is a mistake.

What is the relationship between color experience and color? Here, I defend the view that it is semantic: color experience denotes color in a code innately known by the perceiver. This semantic theory contrasts with a variety of theories according to which color is defined as the cause of color experience (in a special set of circumstances). It also contrasts with primary quality theories of color, which treat color as (...) a physical quantity. I argue that the semantic theory better accounts for the kinds of knowledge we have regarding both the color of objects that we see and of the colors themselves. (shrink)

The dominant view among philosophers of perception is that color experiences, like color judgments, are essentially representational: as part of their very nature color experiences possess representational contents which are either accurate or inaccurate. My starting point in assessing this view is Sydney Shoemaker’s familiar account of color perception. After providing a sympathetic reconstruction of his account, I show how plausible assumptions at the heart of Shoemaker’s theory make trouble for his claim that color experiences (...) represent the colors of things. I consider various ways of trying to avoid the objection, and find all of the responses wanting. My conclusion is that we have reason to be skeptical of the orthodox view that color experiences are constitutively representational. (shrink)

Can the phenomenal character of perceptual experience be altered by the states of one's cognitive system, for example, one's thoughts or beliefs? If one thinks that this can happen then one thinks that there can be cognitive penetration of perceptual experience; otherwise, one thinks that perceptual experience is cognitively impenetrable. I claim that there is one alleged case of cognitive penetration that cannot be explained away by the standard strategies one can typically use to explain away alleged (...) cases. The case is one in which it seems subjects' beliefs about the typical colour of objects affects their colour experience. I propose a two-step mechanism of indirect cognitive penetration that explains how cognitive penetration may occur. I show that there is independent evidence that each step in this process can occur. I suspect that people who are opposed to the idea that perceptual experience is cognitively penetrable will be less opposed to the idea when they come to consider this indirect mechanism and that those who are generally sympathetic to the idea of cognitive penetrability will welcome the elucidation of this plausible mechanism.

Contrary to some well-known views in cognitive science and the philosophy of mind, in general it is not the case that the felt character of sensory experiences is determined by the information that these experiences pick up, or represent, about the world. In this dissertation I shall focus on a particular sensory modality, namely color vision, to support this thesis. ;Recently there has arisen a strong and popular view of phenomenal consciousness according to which the two fundamental problems about (...) the mind: intentionality and phenomenal experience, can be traced back to just one: intentionality. On this view, the phenomenal aspect of experience is a special case of intentionality, or our mental states' carrying information about the external world. For instance, when we see the colors of objects, we see, in a direct and transparent way, exactly those kinds of properties that the external objects have. Not only are the colors of objects causally responsible for our experiences as of color, object colors crucially determine what is called the phenomenal character of color experience. ;In this dissertation I shall argue that this view of color experience---the view called representational externalism---cannot be correct. I shall argue that from the empirical facts about object color and color vision we need not conclude that object colors do not exist, hence color vision is a grand illusion, however, we do have to conclude from these facts that though object colors are the causes of our color experience, what it is like to see the colors is not, in any theoretically interesting sense, determined by the colors themselves. To the contrary, what it is like to see the colors is crucially determined by how our color vision systems are constructed. In this dissertation I offer two independent arguments to support this claim. (shrink)

In this paper I argue that color is a relational feature of the distal objects of perception, a way of appearing. I begin by outlining three constraints any theory of color should satisfy: physicalism about the non‐mental world, consistency with what is known from color science, and transparency about color experience. Traditional positions on the ontological status of color, such as physicalist reduction of color to spectral reflectance, subjectivism, dispositionalism, and primitivism, fail, I (...) claim, to meet all three constraints. By treating color as a relational property, a way of appearing, the three constraints can be met. However, serious problems for this view emerge when considering the relation between illusory color experiences and veridical color experiences. I do not propose a solution to these problems.

Anyone who is a color eliminativist‐i.e., believes that the physical world is colorless‐must explain how our sense experience of color can be so systematically illusory. As it turns out, it is difficult to do this without committing oneself to dualism. In this paper I explore the options available to the color eliminativist in this regard, and argue that his/her prospects are more promising, though still far from certain, if s/he adopts the position that sense experience (...) is strictly intentional. (shrink)

Despite a wealth of data we still have no clear idea what color experiences represent. In fact, color experiences vary with so many factors that it has been claimed that they do not represent anything at all. The primary challenge for any representational account of color experience is to accommodate the various psychophysical results that demonstrate that color appearance depends not only on the spectral nature of the target but also on the spectral, spatial and (...) figural nature of the surround. A number of theorists have proposed that this dependence is an aspect of the visual system's constancy mechanism. However this does not in and of itself tell us what, if anything, is represented in color experience. Ultimately the answer to this question will be informed by one's theory of representational content. I will argue that adopting a molecular scheme of representation enables the development of an account of the represented object of color experience that can do justice to the psychophysical data. (shrink)

Color experience is structured. Some ?unique? colors (red, green, yellow, and blue) appear as ?pure,? or containing no trace of any other color. Others can be considered as a mixture of these colors, or as ?binary colors.? According to a widespread assumption, this unique/binary structure of color experience is to be explained in terms of neurophysiological structuring (e.g., by opponent processes) and has no genuine explanatory basis in the physical stimulus. The argument from structure builds (...) on these assumptions to argue that colors are not properties of surfaces and that color experiences are neural processes without environmental counterparts. We reconsider the argument both in terms of its logic and in the light of recent models in vision science which point at environment-involving patterns that may be at the basis of the unique/binary structure of color experience. We conclude that, in the light of internal and external problems which arise for it, the argument from structure fails. (shrink)

Phenomenal intentionality is a view about the representational content of conscious experiences that grounds the content of experiences in their phenomenal character. The view is motivated by evidence from introspection, as well as theoretical considerations and intuitions. This paper discusses one potential problem with the view. The view has difficulty accounting for the intentionality of color experiences. Versions of the view either fail to count things as part of the content of color experience that should be counted, (...) resulting in verdicts that some color experiences are inaccurate which should not be, or they admit properties as part of their contents that ought not to be admitted, resulting in color experiences being considered to be accurate when they ought not to be considered so. This is a problem because color predicates are usefully employed in sciences such as biology, cognitive science, and engineering. They are used in generalizations that take the form of laws governing the presence and behavior of properties. Scientific practice relies on the assumption that the laws governing how entities behave employ terms that refer to actual properties that entities really have. We should therefore assume that there is some consistent set of properties to which our color terms refer. (shrink)

The aim of this paper is to analyze the relationship between phenomenal experience and our folk conceptualization of it. I will focus on the phenomenal concept strategy as an answer to Mary's puzzle. In the first part I present Mary's argument and the phenomenal concept strategy. In the second part I explain the requirements phenomenal concepts should satisfy in order to solve Mary's puzzle. In the third part I present various accounts of what a phenomenal concept is, and I (...) show the difficulties each of them have. Finally, I develop my own account of phenomenal concepts. My thesis claims that phenomenal concepts are complex concepts whose possession conditions depend upon the mastery of many other concepts, in fact, quite complex concepts such as the distinction between appearance and reality (which belongs to our theory of mind system), and color concepts (at least in the case of the phenomenal concepts needed in order to account for Mary's case). And these later concepts are concepts that have special possession conditions: they include the deployment of nonconceptual recognitional capacities. (shrink)

Color is an incredibly controversial topic. Here is a sample of views taken seriously: colors are dispositions to look coloured; colors are physical properties of surfaces or of light; colors are properties of certain mental states, which get projected onto the surfaces of objects or onto reflected or transmitted light; colors are an illusion; colors are sui generis. One hopes to break the impasse by finding a compelling starting point—one drawing on obvious points that are common ground—which naturally evolves (...) into the theory of color one likes. I start with remarks about the utility of having mental states with a phenomenology, remarks which are, I urge, non-controversial. I develop them into the theory of color I favor. According to it, colors are properties of objects as objective as their shapes. The final section explains how the theory handles the best argument for subjectivism about color. (shrink)

RésuméPaul Boghossian et David Velleman ont soutenu que les théories physicalistes des couleurs — celles qui identifient les propriétés de couleur avec certaines propriétés physiques des objets ou de la lumière—ne peuvent accommoder l'intuition profonde selon laquelle nous ne pouvons pas être dans l'erreur au sujet des contenus représentationnels de nos expériences de couleur. Contre Boghossian et Velleman, je soutiens que cette intuition prétendue que les théories physicalistes ne réussisssent pas à accommoder, nest pas elle-même intuitivement plausible. En fait, c'est (...) clairement un avantage des théories physicalistes que selon elles, les experiences de couleur n'affichent pas avec evidence leurs contenus représentationnels. (shrink)

Fiona Macpherson (2012) argues that various experimental results provide strong evidence in favor of the cognitive penetration of perceptual color experience. Moreover, she proposes a mechanism for how such cognitive penetration occurs. We argue, first, that the results on which Macpherson relies do not provide strong grounds for her claim of cognitive penetrability; and, second, that, if the results do reflect cognitive penetrability, then time-course considerations raise worries for her proposed mechanism. We base our arguments in part on (...) several of our own experiments, reported herein. (shrink)

Physicalism about colour is the thesis that colours are identical with response-independent, physical properties of objects. I endorse the Argument from Structure against Physicalism about colour. The argument states that Physicalism cannot accommodate certain obvious facts about colour structure: for instance, that red is a unitary colour while purple is a binary colour, and that blue resembles purple more than green. I provide a detailed formulation of the argument. According to the most popular response to the argument, the Physicalist can (...) accommodate colour structure by explaining it in terms of colour experience. I argue that this response fails. Along the way, I examine other interesting issues in the philosophy of colour and colour perception, for instance the relational structure of colour experience and the description theory of how colour names refer.

In this paper I address the question of whether the fact that our colour experiences have a finer‐grained content than our ordinary colour concepts allow us to represent should be taken as a threat to theories of the conceptual content of experience. In particular, I consider and criticise McDowell's response to that argument and propose a possible development of it. As a consequence, I claim that the role of the argument from the finer‐grained content of experience has to (...) be redefined. In particular, I acknowledge that this problem is helpful in order to bring to the fore the issue of the proper characterisation of the constraints upon the possession conditions of perceptual demonstrative concepts. Yet, I contend that, in light of the foregoing discussion, it is neutral with respect to the dispute between conceptual and non‐conceptual theorists. For that dispute hinges on whether it is possible to have experiences with a certain content independently of having the concepts, which are needed for its canonical specification and not on whether those experiences are conceptualisable in all their finesse of grain.

In the debate over whether mathematical facts, properties, or entities explain physical events (in what philosophers call “extra-mathematical” explanations), Aidan Lyon’s (2012) affirmative answer stands out for its employment of the program explanation (PE) methodology of Frank Jackson and Philip Pettit (1990). Juha Saatsi (2012; 2016) objects, however, that Lyon’s examples from the indispensabilist literature are (i) unsuitable for PE, (ii) nominalizable into non-mathematical terms, and (iii) mysterious about the explanatory relation alleged to obtain between the PE’s mathematical explanantia and (...) physical explananda. In this paper, I propose a counterexample to Saatsi’s objections. My counterexample is Frank Jackson’s (1998a) program explanation for color experience, which I argue needs recasting as an extra-mathematical PE due to its implicit reliance on reflectance, a property that suffers conceptual regress unless redefined with Fourier harmonics. Pace Saatsi, I argue that this recast example is an authoritative PE, non-nominalizable, and minimally esoteric. Important for the indispensability debate at large, moreover, is that my counterexample reifies Fourier harmonics without the Enhanced Indispensability Argument (an argument to which Lyon applies PE as a premise). Indispensabilists have long overlooked the conditionalization of a limited mathematical realism on property realism, and my counterexample to Saatsi exploits this conditionalization. (shrink)

In previous work, I have defended a non-standard version of intentionalism about perceptual experience. According to the doxastic account, visual experience is a peculiar kind of belief: belief with “phenomenal” or looks-content. In this paper, I investigate what happens if this account of experience is combined with another idea I find very plausible: That the colors are to be understood in terms of color experience. I argue that the resulting phenomenal account of color (...) class='Hi'>experience captures everything essential to what has been called the “natural concept of color”. And I show that circularity worries are not aggravated by adopting this account instead of more standard forms of intentionalism—rather, they can be dispelled along the same lines. (shrink)

In this Response, I defend the notion of intrinsic qualities of experience, discuss the distinction between relational experience and relational structure, clarify the difference between narrow and broad interpretations of color experience, argue against externalist approaches to color experience, defend the concept of isomorphism as a limitation in understanding color experiences, examine critiques of the color machine and color room arguments, and counter objections to within-subject experiments based on memory limitations.

Hardin argues that Reflectance Physicalism about color fails because it cannot accommodate color structure. David Lewis and others have replied that the Reflectance Physicalist may explain color structure in terms of color experience. I argue that this reply fails.

It has been suggested that difficult-to-quantify differences in visual processing may prevent researchers from equating the color experience of different observers. However, spectral locations of unique hues are remarkably invariant with respect to everything other than gross differences in preretinal and photoreceptor absorptions. This suggests a stereotyping of neural color processing and leads us to posit that minor differences in observer neurophysiology may be irrelevant to color experience.

Palmer demarcates the bounds of our understanding of color experience by symmetries in the color space. He claims that if there are symmetries, there can be functionally undetectable color transformations. However, even if there are symmetries, Palmer's support for the possibility of undetectable transformations assumes phenomenal internalism. Alternatively, phenomenal externalism eliminates Palmer's limit on our understanding of color experience.

Frank Jackson has a new objectivist and representationalist account of the content of colour-experience. I raise several objections both against the account itself and, primarily, against how he tries to support it. He argues that the new account enables us to see what is wrong with the so-called Opacity Puzzle. This alleged puzzle is an argument in which a seemingly implausible conclusion is derived from three premises of which seem plausible to an representationalist. Jackson’s diagnosis of the puzzle as (...) a fallacy of equivocation is mistaken. The term ‘‘the property of being red’’ is not ambiguous in the way he claims it to be, and the puzzling argument is valid. Moreover, its conclusion is not implausible, so after all there is no real puzzle. I try to show how Jackson’s wrong diagnosis results from neglecting the difference between properties proper and properties as conceived in the light of a given property-concept. (shrink)

The paradox of girls’ academic gains over boys, across race and class, has perplexed scholars for the last few decades. Through a 3-year longitudinal ethnography of two predominantly economically marginalized and racially minoritized schools, I contend that while racially marginalized girls may have made academic gains, school is nevertheless a hostile institution for them. Focusing on the case of Black girls and recent immigrant girls of color, I identify three specific ways in which school functions as hostile institution for (...) them: gendered racial harassment from teachers, erasure of intellect, and estrangement within their communities. Furthermore, the denigration of immigrant girls becomes the conduit for misogynoir. I find that the gains of some racially marginalized girls in school often justify hostility against all of them. Bringing into conversation a feminist analysis of schooling that rejects girls’ educational gains as ubiquitous evidence of a gender revolution with a Black-colonial education framework that emphasizes schooling as a technology of oppression, I explore the current role of school as a hostile institution for Black girls and immigrant girls of color.

Palmer (1999) and the commentators examine whether qualia are produced by the relational processes of functionalism. This is an exploration of how qualia are produced. The wealth of data provided by the target article and the commentaries also provide information about what qualia are. The present commentary further explores this topic.

I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for binary colours or colour mixtures. I argue that none of these strategies is successful and therefore that one cannot fully explain the nature of (...) the phenomenal character of perceptual experiences using a naturalistic conception of representation.

I argue that Husserl’s account of passive synthesis can be developed into a phenomenology of peripheral experience. Peripheral experiences are not defined by their location in visual space but by their phenomenal and intentional character, by what these experiences are like and how they present things in the world. Further, I argue that peripheral experience is of a piece with our most basic background convictions about the world. As such, the periphery is epistemically neutral, but not therefore empty (...) of meaning. It is meaningful as holding open the possibility of further activity, both practical and intellectual. I explore these ideas by focusing on peripheral color experience. Husserl’s discussions of associative synthesis, affection, and doxic and nondoxic forms of attention prove key to detailing peripheral color experience. I end by arguing that at the periphery, intentional content and phenomenal content come apart. (shrink)

This article examines the early modern household's importance for producing experimental knowledge through an examination of the Halifax household of Margery and Henry Power. While Henry Power has been studied as a natural philosopher within the male-dominated intellectual circles of Cambridge and London, the epistemic labour of his wife, Margery Power, has hitherto been overlooked. From the 1650s, this couple worked in tandem to enhance their understanding of the vegetable world through various paper technologies, from books, paper slips and recipe (...) notebooks to Margery's drawing album and Henry's published Experimental Philosophy. Focusing on Margery's practice of hand-colouring flower books, her copied and original drawings of flowers and her experimental production of ink, we argue that Margery's sensibility towards colour was crucial to Henry's microscopic observations of plants. Even if Margery's sophisticated knowledge of plants never left the household, we argue that her contribution was nevertheless crucial to the observation and representation of plants within the community of experimental philosophy. In this way, our article highlights the importance of female artists within the history of scientific observation, the use of books and paperwork in the botanical disciplines, and the relationship between household science and experimental philosophy.

Subfocal Color Categorization and Naming: The Role of Exposure to Language and Professional Experience The current state of the debate on the linguistic factors in color perception and categorization is reviewed. Developmental and learning studies were hitherto almost ignored in this debate. A simple experiment is reported in which 20 Academy of Fine Arts, Faculty of Painting students' performance in color discrimination and naming tasks was compared to the performance of 20 Technical University students. Subfocal colors (...) were used. While there was no difference in overall discrimination ability, AFA students had a much richer and specialized color vocabulary. Both groups also applied different strategies of discrimination and naming. However, naming system in neither group was coherent. This suggests that naming played primarily the role of markers for control processes rather than names for categories. It is concluded that up-to-date debate is too simplified and a complex model of interrelations between perceptual categorization and naming framed in the developmental context is needed rather than the search for a simple answer "language", "environment", or "perceptual universals".

In this major reinterpretation, Howard Caygill argues that all of Benjamin's work is characterized by its focus on a concept of experience derived from Kant but applied by Benjamin to objects as diverse as urban experience, visual art, literature and philosophy. The book analyzes the development of Benjamin's concept of experience in his early writings showing that it emerges from an engagement with visual experience, and in particular the experience of colour. By representing Benjamin as (...) primarily a thinker of the visual field, Caygill is able to bring forward previously neglected texts on inscription and the visual field and to cast many of his more familiar texts, for instance the Work of Art in an Age of Mechanical Reproduction in a new light.

I have two main goals in this paper. My first goal is to sketch a new view of color perception. The core of the view can be expressed in the following two theses: (i) the overarching function of color vision is to enable and enhance the manifestation of relevant (species-specific) competences and (ii) color experiences are correct when they result from processing that directly and non-accidentally subserves the manifestation of such competences. My second goal is to show (...) that the view can accommodate and account for a wide variety of color perceptual phenomena, including many problem cases. Importantly, the framework allows us to differentiate between two kinds of good cases of color perception: ideal cases where the demands of the relevant competences converge and non-ideal cases where the demands of the relevant competences diverge and clash.

The Four-Colour Theorem (4CT) proof, presented to the mathematical community in a pair of papers by Appel and Haken in the late 1970's, provoked a series of philosophical debates. Many conceptual points of these disputes still require some elucidation. After a brief presentation of the main ideas of Appel and Haken’s procedure for the proof and a reconstruction of Thomas Tymoczko’s argument for the novelty of 4CT’s proof, we shall formulate some questions regarding the connections between the points raised by (...) Tymoczko and some Wittgensteinian topics in the philosophy of mathematics such as the importance of the surveyability as a criterion for distinguishing mathematical proofs from empirical experiments. Our aim is to show that the “characteristic Wittgensteinian invention” (Mühlhölzer 2006) – the strong distinction between proofs and experiments – can shed some light in the conceptual confusions surrounding the Four-Colour Theorem.
