ABSTRACT
The appearance of consciousness in the world is an amazing and puzzling fact in its own right. Indeed, consciousness is one of the most mystifying features of the cosmos. The unity of consciousness is something that cries out for analysis and explanation in its own right. Perhaps more than anyone else in the literature, Tim Bayne and David Chalmers have done the most careful thinking about the unity of consciousness, although, Bayne is the chief current thinker on these matters. More than anyone else, William Hasker has championed this argument for substance dualism. This is just a brute assertion, and, indeed, an assertion that he needs to avoid substance dualism. The first reason that the unity of consciousness is a problem is the simple fact that it is an interesting set of philosophical problems in its own right. But there is a deeper and more pervasive problem lurking in the neighborhood.
