AbstractPhilosophy of mind concerns questions about mental phenomena that empirical research alone can't settle, such as the nature of mental states and which sorts of things can have them—only living things, or also machines? Settling them requires reflection on such phenomena as consciousness, rationality, and intentionality; the ‘explanatory gaps’ that seem to exist between these; and underlying physical phenomena and the different strategies—dualist, eliminativist, physicalist, and functionalist—that have been proposed for dealing with them.
