From the 1950s, the trend was towards dynamic approaches. The ideas of sociologists like Max Weber began to stir interest. In anthropology it was first the transactionalists like Fredrik Barth, and then the Manchester School. This chapter focuses on these dynamics and particularly on three important ethnographic debates: Friedman versus Leach, Wilmsen versus Lee, and Obeyesekere versus Sahlins. These debates highlight the fact that anthropology is not without dispute in its interpretation.
