Jaegwon Kim's "Supervenience and Mind: Selected Philosophical Essays" is an absolute must-read for any philosopher working in the philosophy of mind. Of particular interest, Kim lays out his views in supervenience and its relation to the mind-body problem, discusses and (in my view) deals a death-blow to Donald Davidson's anomalous monism, and begins the development of his views on reductionism that come to fruition in his "Mind in a Physical World" (also a great read). Kim's work is a paradigm of thoroughness, both in material covered and the scope of his application of a few key ideas. Also of particular interest is Kim's work in event theory, which is developed in the first few essays, and which, though neglected for some time, has been the subject of several recent journal articles in application to problems associated with natural kinds.

All-in-all, a great set of essays by, in my view, one of the greatest living philosophers.
