“Why spirits?” asks Emma Cohen (97)—why are concepts of intentional and agentive supernatural beings such as spirits and gods so prevalent cross-culturally? What makes them appealing, contagious, and lasting? And what kinds of assumptions about the world and its workings do they entail and do they generate? In The Mind Possessed, Cohen offers us some answers; to some degree by appealing to her ethnography of the Afro-Brazilian practice of batuque in the Amazon-bordering town of Belém, but mostly by subordinating particularistic concerns to what she considers more general ‘scientific’ ones. However, it may be the questions, rather than the answers, that merit revising.
