Magic, Science and Society investigates the way the ‘rationality debate’ has developed over the last century, from E.E. Evans-Pritchard’s study of Azande magic, through Peter Winch’s argument that there can be no such thing as a social science, across the arguments about the proper status of science in the 1970s and 1980s, to the ‘epistemological’ and ‘ontological’ turns of the early twenty-first century.
