In this paper, I defend a representationalist account of the phenomenal character of color experiences. Representationalism, the thesis that phenomenal character supervenes on a certain kind of representational content, so-called phenomenal content, has been developed primarily in two different ways, as Russellian and Fregean representationalism. While the proponents of Russellian and Fregean representationalism differ with respect to what they take the contents of color experiences to be, they typically agree that colors are exhaustively characterized by the three dimensions of the color solid: hue, saturation, and lightness. I argue that a viable version of representationalism needs to renounce this restriction to three dimensions and consider illumination to be a genuine phenomenal dimension of color. My argument for this thesis falls into two parts. I first consider the phenomenon of color constancy in order to show that neither Russellian nor Fregean representationalism can do justice to the phenomenal significance of local illumination. I subsequently formulate a version of representationalism that accounts for illumination by taking it as a phenomenal dimension of color.

In recent years, several philosophers have defended the idea of phenomenal intentionality: the intrinsic directedness of certain conscious mental events which is inseparable from these events’ phenomenal character. On this conception, phenomenology is usually conceived as narrow, that is, as supervening on the internal states of subjects, and hence phenomenal intentionality is a form of narrow intentionality. However, defenders of this idea usually maintain that there is another kind of, externalistic intentionality, which depends on factors external to the subject. We may ask whether this concession to content externalism is obligatory. In this paper, I shall argue that it isn’t. I shall suggest that if one is convinced that narrow phenomenal intentionality is legitimate, there is nothing stopping one from claiming that all intentionality is narrow.

This thesis is an examination and critique of naturalistic representational theories of phenomenal character. Phenomenal character refers to the distinctive quality that perceptual and sensational experiences seem to have; it is identified with 'what it is like' to undergo experiences. The central claims of representationalism are that phenomenal character is identical with the content of experience and that all representational states, bearing appropriate relations to the cognitive system, are conscious experiences. These claims are taken to explain both how conscious experiential states arise and their nature. After examining the desiderata for naturalistic explanations, I argue that theories which ascribe nonconceptual content to experiences are the most plausible versions of representationalism. Further, causal covariation and teleological theories yield distinctive and interesting representationalist positions, hence, they become the focus of this study. To assess representationalism, I investigate whether all differences in phenomenal character can be correlated with differences in content. I claim that a useful distinction can be drawn between implicit and explicit content, which allows one to best describe the phenomena of perfect and relative pitch. I then argue that ambiguous figures show that two experiences can have the same content but different phenomenal character. I explicate the Inverted Earth hypothesis and claim that to identify content and phenomenal character, representationalists either have to condone the possibility of philosophical zombies, or hold that people lack authoritative first-person knowledge of their current experiences. Both these positions are unpalatable. Finally, I argue that representationalists cannot ascribe contents to experiences of novel colours to account for their phenomenal character. I also question, in light of dissociation phenomena, whether there is one distinctive relationship that all experiences bear to the cognitive system. I conclude that phenomenal character cannot be identical with the type of content under investigation, and that naturalistic representationalist theories cannot fully explain conscious experience.

Gray argues that my three earlier counterexamples fail to refute representational theories of phenomenal character. I maintain that, despite Gray's arguments, each example does in fact work against the particular representational theory at which it is targeted. Further, I question whether my internalism regarding phenomenal character and Gray's externalism regarding modularity are in genuine conflict with one another.

1. Introduction When it comes to perception, representationalism is all the rage. Representationalism is a claim about the phenomenal character of perceptual experiences: According to representationalism, phenomenal character is fully determined by the representational content of perceptual experiences (cf. Tye 2002, 45). In other words, phenomenal character, what it is like, for instance, to have an experience as of something red, is either supervenient upon or identical with that experience.

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal concepts. My arguments exploit the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails.

: Although Externalism is widely accepted as a thesis about belief, as a thesis about experience it is both controversial and unpopular. One potential explanation of this difference involves the phenomenality of perceptual experience—perhaps there is something about how perceptual experiences seem that straightforwardly speaks against Externalist accounts of their individuation conditions. In this paper, I investigate this idea by exploring the role that the phenomenality of color experience plays in a prominent argument against Phenomenal Externalism: Ned Block’s Inverted Earth Argument. In the course of carrying out this investigation, I will show that challenging Phenomenal Externalism on phenomenological grounds is not as straightforward a task as it is commonly assumed to be.

Combining phenomenological insights from Brentano and Sartre, but also drawing on recent work on consciousness by analytic philosophers, this book defends the view that conscious states are reflexive, and necessarily so, i.e., that they have a built-in, implicit awareness of their own occurrence, such that the subject of a conscious state has an immediate, non-objectual acquaintance with it. As part of this investigation, the book also explores the relationship between reflexivity and the phenomenal, or what-it-is-like, dimension of conscious experience, defending the innovative thesis that phenomenal character is constituted by the implicit self-awareness built into every conscious state. This account stands in marked contrast to most influential extant theories of phenomenal character, including qualia theories, according to which phenomenal character is a matter of having phenomenal sensations, and representationalism, according to which phenomenal character is constituted by representational content.

[…] One view I hold about the nature of phenomenal character, which is also a view about the relation between phenomenal character and the introspective belief about it, is that phenomenal character is “self intimating.” This means that it is of the essence of a state’s having a certain phenomenal character that this issues in the subject’s being introspectively aware of that character, or does so if the subject reflects. Part of my aim is to give an account which makes it intelligible that this should be so. A more substantive view I hold about phenomenal character is that a perceptual state’s having a certain phenomenal character is a matter of its having a certain sort of representational content. This much I hold in common with a number of recent writers, including Gil Harman, Michael Tye, Bill Lycan, and Fred Dretske. But representationalism about phenomenal character often goes with the rejection of “qualia,” and with the rejection of the possibility of spectrum inversion and other sorts of “qualia invesion.” My version of representationalism embraces what other versions reject. It assigns an essential role to qualia, and accepts the possibility of qualia inversion. A central aim of the present paper is to present a version of this view which is free of the defects I now see in my earlier versions of it.
