Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the problem of consciousness. It mischaracterises the problem by presenting consciousness as more "colour-like" than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can't rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the "explanatory gap" that consciousness gives rise to.

It is widely assumed that ‘consciousness’ (and its cognates) is multiply ambiguous within the consciousness literature. Some alleged senses of the term are access consciousness, phenomenal consciousness, state consciousness, creature consciousness, introspective consciousness, self consciousness, to name a few. In the paper I argue for two points. First, there are few if any good reasons for thinking that such alleged senses are genuine: ‘consciousness’ is best viewed as univocal within the literature. The second point is that researchers would do best to avoid the semantics of ‘consciousness’, since resorting to “semantic ascent” typically serves no clear purpose in the case of consciousness, and confuses matters more than anything else.

This paper is an edited transcription of a talk at the 1997 Montreal symposium on "Consciousness at the Frontiers of Neuroscience". There's not much here that isn't said elsewhere, e.g. in "Facing Up to the Problem of Consciousness" and "How Can We Construct a Science of Consciousness?"]].

What place does consciousness have in the natural world? If we reject materialism, could there be a credible alternative? In one classic example, philosophers ask whether we can ever know what is it is like for bats to sense the world using sonar. It seems obvious to many that any amount of information about a bat's physical structure and information processing leaves us guessing about the central questions concerning the character of its experience. A Place for Consciousness begins with reflections on the existence of this gap. Is it just a psychological shortcoming in our merely human understanding of the physical world? Is it a trivial consequence of the simple fact that we just cannot be bats? Or does it mean there really are facts about consciousness over and above the physical facts? If so, what does consciousness do? Why does it exist? Rosenberg sorts out these problems, especially those centering on the causal role of consciousness. He introduces a new paradigm called Liberal Naturalism for thinking about what causation is, about the natural world, and about how to create a detailed model to go along with the new paradigm. Arguing that experience is part of the categorical foundations of causality, he shows that within this new paradigm there is a place for something essentially like consciousness in all its traditional mysterious respects. A striking feature of Liberal Naturalism is that its central tenets are motivated independently of the mind-body problem, by analyzing causation itself. Because of this approach, when consciousness shows up in the picture it is not introduced in an ad hoc way, and its most puzzling features can be explained from first principles. Ultimately, Rosenberg's final solution gives consciousness a causally important role without supposing either that it is physical or that it interacts with the physical.

The relation between subjective consciousness and the physical brain is widely regarded as the last mystery facing science. Papineau argues that consciousness seems mysterious not because of any hidden essence, but only because we think about it in a special way. He exposes the resulting potential for confusion, and shows that much scientific study of consciousness is misconceived.

My topics are consciousness. The plural is deliberate. Both in philosophy and in psychology,.

In recent philosophy of mind, it is often assumed that consciousness and self-consciousness are two separate phenomena. In this paper, I argue that this is not quite right. The argument proceeds in two phases. First, I draw a distinction between (i) being self-conscious of a thought that p and (ii) self-consciously thinking that p. I call the former transitive self-consciousness and the latter intransitive self-consciousness. I then argue that consciousness does depend on intransitive self-consciousness, and that the common reasons for denying the dependence of consciousness upon self-consciousness apply only to transitive self-consciousness.
