Computation, levels of abstraction, and the intrinsic character of experience

Palmer's color room argument is first contrasted with a different argument by Tim Maudlin against the sufficiency thesis of strong AI. This thesis tur ns out to be false and hence we need to determine the relevant supervenienc e base of phenomenal consciousness. That could Le done by causal theories a nd intraindividual experiments. Finally, even if we cannot explain the intr insic character of conscious states, we may be able to know what the experi ence of another person is like.
