Realization

So far no clear explication of the notion of realization has been offered, in spite of the frequent uses of the notion in the literature to discharge important jobs, such as that of accounting for the causal efficacy of the mental in a physical world, and that of providing a viable characterization of physicalism, and/or psychophysical reduction. I put forward an account of realization as an identity-like relation. I argue that such account has the following advantages: (a) it provides a picture under which it makes sense to use the same term, i.e. 'realization', to pick out relations that differ in their relata, as it happened in the original uses of the term 'realization'; (b) it helps to understand how well, if at all, some appeals to realization in the literature can discharge the jobs mentioned; (c) more generally, it makes clear what realization can do.
