Representationism is the view that the phenomenal character of an experience supervenes on its representational content. Synaesthesia is a condition in which the phenomenal character of the experience produced in a subject by stimulation of one sensory modality contains elements characteristic of a second, unstimulated sensory modality. After reviewing some of the recent psychological literature on synaesthesia and one of the leading versions of representationism, I argue that cases of synaesthesia, as instances of what I call the extra qualia problem, are counterexamples to externalist versions of representationism.

From now on I will assume that it is possible in principle for there to be cases of spectrum inversion in which the invertees are equally good perceivers of the colors. What I want to show next is that while allowing this possibility is incompatible with standard representationalism, it requires acceptance of a different version of representationalism. Consider the standard way of describing a case of spectrum inversion. Returning to Jack and Jill, we say that red things look to Jack the way green things look to Jill, blue things look to Jack the way yellow things look to Jill, and so on. Of course, we might also express this by saying that the phenomenal character of Jack’s experience of red things is like the phenomenal character of Jill’s experience of green things, and so on. Or by saying that “what it is like” for Jack to see red things is “what it is like” for Jill to see green things, and so on. But “phenomenal character” is philosophical jargon, and “what it is like” is on its way to being that. We need to be able cash these locutions in terms that we are sure we understand. And I think that the best way of doing that is in terms of how things look. Now the sense in which red things look different to Jack and Jill cannot be that they look to have different colors in the epistemic sense. We can suppose that both perceive red things as being red, and therefore that to both red things look red in the epistemic sense. Nor can it be the comparative sense – to each, we can suppose, red things look like standard red things under standard conditions. The remaining sense of “looks” is supposed to be the phenomenal sense. Now those who employ this notion typically speak of things as looking red, blue, yellow, etc., in the phenomenal sense. But if Jack and Jill are both accurate perceivers of the colors of things, it can’t be that the difference in how things look to them is a difference in what colors things look to them, even if “looks” is used in the phenomenal sense..

Representational theories of mind cannot individuate the sense modalities in a principled manner. According to representationalism, the phenomenal character of experiences is determined by their contents. The usual objection is that inverted qualia are possible, so the phenomenal character of experiences may vary independently of their contents. But the objection is inconclusive. It raises difficult questions about the metaphysics of secondary qualities and it is difficult to see whether or not inverted qualia are possible. This paper proposes an alternative test of representationalism. Do experiences in different sense modalities have the same phenomenal character when they share content? Psychological work on the perception of shape through vision and spatial hearing is discussed. This work shows that visual and auditory experiences differ in phenomenal character even in so far as they represent similar properties. This objection to representationalism does not invite questions about secondary qualities or depend on establishing metaphysical possibilities.

According to a currently popular approach to the analysis of phenomenal character, the phenomenal character of an experience is entirely determined by, and is in fact identical with, the experience's representational content. Two underlying assumptions motivate this approach to phenomenal character: (1) that conscious experiences are diaphanous or transparent, in the sense that it is impossible to discern, via introspection, any intrinsic features of an experience of x that are not experienced as features of x, and (2) that the immediate objects of consciousness are not objects per se, but rather properties. This paper explores these assumptions, advancing the thesis that each is rejectable on phenomenological grounds.

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.

Phenomenal consciousness is the property mental states, events, and processes have when, and only when, there is something it is like for their subject to undergo them, or be in them. What it is like to have a conscious experience is customarily referred to as the experience’s phenomenal character. Theories of consciousness attempt to account for this phenomenal character. This article surveys the currently prominent theories, paying special attention to the various attempts to explain a state’s phenomenal character in terms of its representational content.

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.

Representationalism is a thesis about the phenomenal character of experiences, about their immediate subjective ‘feel’.1 At a minimum, the thesis is one of supervenience: necessarily, experiences that are alike in their representational contents are alike in their phenomenal character. So understood, the thesis is silent on the nature of phenomenal character. Strong or pure representationalism goes further. It aims to tell us what phenomenal character is. According to the theory developed in Tye 1995, phenomenal character is one and the same as representational content that meets certain further conditions. One very important motivation for this theory is the so-called ? transparency of experience.? The purpose of this paper is to elucidate the appeal to transparency more carefully than has been done hithertofore, to make some remarks about the introspective awareness of experience in light of this appeal, and to consider one problem case for transparency at some length, that of blurry vision. Along the way, I shall also address some of the remarks Stephen Leeds makes in his essay on transparency.

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.

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all.
