The problem of consciousness arises when we accept that humans are subject to conscious experiences, and that these experiences resist explanations of a kind that other puzzling phenomena permit. I first consider the case that such experiences exist and then the reasons for taking a pessimistic view of our chances of explaining them. I argue that the fact that conscious experience is ineffable makes the problem even harder than Chalmers allows, as it undermines a presentation of the problem of reductive (...) explanation in this case. The fact that conscious phenomena require a first-person perspective provides a further reason for taking a pessimistic view of the chances for the kind of theory that Chalmers seeks. In a final section I consider what form solutions to the problem, as revised, might take. (shrink)
