[L]). Quasi-realism in mathematics, The Monist
- P. Sch. Lindström
It has often been argued that the theory of psycho-neural identity must be wrong because it contradicts Leibniz’ law. Some philosophers, for example John Heil, has tried to deal with this problem by relying on a distinction between the experience of phenomenal objects and these objects themselves. The point with the distinction is that it might be less problematic to identify experiences with brain states than to identify phenomenal objects or states with brain states. The distinction can also be of interest from a functionalist point of view. In this paper I argue that it is questionable if such a distinction can be drawn, and if it is drawn, it is questionable if it really solves the problems that it is designed to solve.
