Arguments about the evolutionary function of phenomenal consciousness are beset by the problem of epiphenomenalism. For if it is not clear whether phenomenal consciousness has a causal role, then it is difficult to begin an argument for the evolutionary role of phenomenal consciousness. We argue that complexity arguments offer a way around this problem. According to evolutionary biology, the structural complexity of a given organ can provide evidence that the organ is an adaptation, even if nothing is known about the causal role of the organ. Evidence from cognitive neuropsychology suggests that phenomenal consciousness is structurally complex in the relevant way, and this provides prima facie evidence that phenomenal consciousness is an adaptation. Furthermore, we argue that the complexity of phenomenal consciousness might also provide clues about the causal role of phenomenal consciousness.

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.

Phenomenal consciousness, what it is like to have or undergo an experience, is typically understood as an empirical item – an actual or possible object of consciousness. Accordingly, the problem posed by phenomenal consciousness for materialist accounts of the mind is usually understood as an empirical problem: a problem of showing how one sort of empirical item – a conscious state – is produced or constituted by another – a neural process. The development of this problem, therefore, has usually consisted in the articulation of an intuition: no matter how much we know about the brain, this will not allow us to see how it produces or constitutes phenomenal consciousness. Developing a theme first explored by Kant, and then later by Sartre, this paper argues that the real problem posed by phenomenal consciousness is quite different. Consciousness, it will be argued, is not an empirical but a transcendental feature of the world. That is, what it is like to have an experience is not something of which we are aware in the having of that experience, but an item in virtue of which the genuine (non-phenomenal) objects of our consciousness are revealed as being the way they are. Phenomenal consciousness, that is, is not an empirical object of awareness but a transcendental condition of the possibility of there being empirical objects of awareness.

be realized. Whatever gets access to phenomenal awareness (to consciousness and P-consciousness are almost always present or P-consciousness as described by Block) is represented within this absent together.

I appeal to Merker's theory to motivate a hypothesis about the ontology of consciousness: Creature consciousness is (at least partially) constitutive of phenomenal consciousness. Rather than elaborating theories of phenomenal consciousness couched solely in terms of state consciousness, as philosophers are fond of doing, a correct approach to phenomenal consciousness should begin with an account of creature consciousness.

"Consciousness" is a multiply ambiguous word, and if our goal is to explain perceptual consciousness we had better be clear about which of the many senses of the word we are endorsing when we sign on to the project. I describe some of the relatively standard distinctions made in the philosophical literature about different meanings of the word "conscious". Then I consider some of the arguments of David Chalmers and of Ned Block that states of "phenomenal consciousness" pose special and intractable problems for the scientific understanding of perception. I argue that many of these problems are introduced by obscurities in the term itself, and propose a distinction between epistemic and non-epistemic senses of the term "phenomenal consciousness". That distinction helps explain why phenomenal consciousness seems so mysterious to so many people. States of "phenomenal consciousness" are not states of one, elemental (and inexplicable) kind; they are a ragtag lot, of differing levels of complexity, corralled under one heading by a regrettable ambiguity in our terminology.

There is not a uniform kind of consciousness common to all conscious mental states: beliefs, emotions, perceptual experiences, pains, moods, verbal thoughts, and so on. Instead, we need a distinction between phenomenal and nonphenomenal consciousness. As if consciousness simpliciter were not mysterious enough, philosophers have recently focused their worries on phenomenal (or qualitative) consciousness, the kind that explains or constitutes there being "something it.

widely held commitments: to phenomenal realism and to naturalism. Phenomenal realism is the view that (a) we are phenomenally consciousness, and that (b) there is no a priori or armchair sufficient condition for phenomenal consciousness that can be stated (non- circularly) in nonphenomenal terms (p.392).^1,2 Block points out that while phenomenal realists reject.

Siewert identifies a special kind of conscious experience, phenomenal consciousness, that is the sort of consciousness missing in a variety of cases of blindsight. He then argues that phenomenal consciousness has been neglected by students of consciousness when it should not be. According to Siewert, the neglect is based at least in part on two false assumptions: (i) phenomenal features are not intentional and (ii) phenomenal character is restricted to sensory experience. By identifying an essential tension in Siewert's characterization of phenomenal consciousness, I argue that his case for denying (i) and (ii) is at best incomplete.
