The materialist thesis that there is a type-type identity between certain mental phenomena and certain physical phenomena has encountered serious criticisms. This paper is to propose a revised form of mind-body identity theory which moves forward from the token identity theory and can stand the major criticism made against the type-type identity theory. In the first part of the paper, through a very brief review of the issue I show what needs to be done; in the second part, I show (...) how my solution avoids the difficulties that have troubled the type-type identity theory.
