Why Reject Substance Dualism?

This chapter draws an analogy between substance dualism (SD) and one kind of creationism. Some substance dualists appear to believe that SD is preferable to physicalism because only the former can account for the existence of morality. Some dualists are attracted to emergence, although it is unclear that it is a form of SD; indeed, it is not clear that it is a form of dualism at all, and if it is it would seem to be a form of property dualism. The chapter discusses SD's relationship to three key elements of religious doctrine and the idea of emergence. It describes most serious arguments for physicalism and consequently against SD. According to SD, mind and brain are radically different substances, the former nonphysical, the latter physical. Advocates of occasionalist SD claim that God appropriately correlates mental and physical events occasion by occasion.
