This book, first published in 1902-1903, in co-authorship with H. Hubert, is one of the classics of Anthropology. Marcel Mauss, disciple and nephew of great French sociologist Emile Durkheim, strongly influenced generations of anthropologists, including Claude Lévi-Strauss. The book stablished a new pattern for understanding the magical and religious phenomena. Unfortunaly, the two previous reviewrs seems to have looking for something very different. It is not a how-to-do book, it is for people interested in the Social Sciences.
