Kim eventually rejected strict physicalism on the grounds that provided an insufficient basis for resolving the mind-body problem. In particular, he concluded that the hard problem of consciousness—according to which a detailed and comprehensive neurophysical description of the brain would still not account for the fact of consciousness—is insurmountable in the context of a thoroughgoing physicalism. His arguments against physicalism can be found in his two latest monographs: "Mind in a Physical World" (1998) and "Physicalism, or Something Near Enough" (2005). Kim claims "that physicalism will not be able to survive intact and in its entirety." This, according to Kim, is because qualia (the phenomenal or qualitative aspect of mental states) cannot be reduced to physical states or processes. Kim claims that "phenomenal mental properties are not functionally definable and hence functionally irreducible" and "if functional reduction doesn't work for qualia, nothing will." Thus, there is an aspect of the mind that physicalism cannot capture.
