CONTEMPORARY MATERIALIST theories of mind, viz. Causal Correspondence and Identity, are usually contrasted with several alleged historical competitors: Parallelism; Epiphenomenalism; Dual aspect; and Emergence. What I shall here attempt to argue is that this last mentioned theory, Emergence, is no competitor at all, but rather is a natural supplement to a materialist theory. I shall try to argue that there is a good case for saying that if, in particular, sensation states are caused by or are identical to brain states, then they are caused by or are identical to emergent brain states.
