Metaphysics of Consciousness discusses the philosophical issue of the nature of consciousness. William Seager argues that the purely physicalist or materialist view of human consciousness is by no means disproved and is in fact strongly supported by some developments in artificial intelligence. William Seager proceeds by addressing the problems of consciousness that remain even for a minimal physicalism. The particular modes of subjective consciousness that constitute experience threaten a paradigm of scientific understanding, labelled "physical resolution," that prospers in all other realms of inquiry. A phenomenon is physically resolved by demonstrating that its components are made up of purely physical parts and its causal efficacy is grounded in the physical properties of parts. The apparent inability to resolve physical consciousness leaves it not only inexplicable, but inexplicable in a way that threatens even a minimal physicalism.
