Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.
