Abstract
This chapter formulates and motivates the current favored articulation of the metaphysical doctrine of materialism. It describes an alternative metaphysical position called minimal emergentism, which has two versions; and then contrasts it with stronger kinds of emergentism. Minimal emergentism posits certain inter-level necessitation relations — either nomically necessary connections, or metaphysically necessary connections — that are metaphysically brute. The chapter sets forth what it takes to be some very powerful challenges to materialism — challenges involving features of human consciousness. Finally, the chapter argues that in light of these challenges, minimal emergentism is a viable and theoretically appealing non-materialist metaphysic of mind.
