Abstract

Purple Haze: The Puzzle of Consciousness, by Joseph Levine, is reviewed. The position that Levine takes in the current philosophical debate about consciousness is identified and the general approach of the essay outlined. I focus on two of the more important issues in the book - the conceivability argument against materialism, and the explanatory gap argument against dualism - and argue that Levine's argument against the former is unconvincing and his diagnosis of the source of the latter leads him into problems. I suggest a more promising route.
