%A Mr Dennis Nicholson %T How qualia can be physical %X Assume that a quale as we experience it is a perspective on an underlying physical state, rather than the physical state as such ? the reality as known as distinct from the reality as such. Assume, further, that this inner perspective is integral to, and materially co-extensive with, the physical state itself. Assume, finally, that the physical state in question is known as a brain state of a particular kind by an external observer of the brain in which it occurs. The result is a perspective in which a quale is entirely physical; a position that resolves several known difficulties for physicalism, including those associated with the explanatory gap, Jackson?s knowledge argument, and Chalmers? hard problem of consciousness. %D 2006 %K qualia, mind-body problem, identity theory, hard problem, knowledge argument %L cogprints4786
