 Thus continual reshuffling is capable of moving, and does move individuals and groups in the society through a variety of transformations in relation to life problems, social problems, technological problems, and the transmission and enrichment of a highly complex cultural system.The book shows how these adjust dynamically to changing social conditions.This book makes major methodological, substantive, and theoretical advances for the disciplines of ethnography, social anthropology, and social history; and marks some new understandings of several of the many forms of social complexity.
