"Built upon decades of experience at the frontiers of history and social science, Charles Tilly's newest book offers innovative methods and approaches applicable in a wide range of disciplines: politics, sociology, anthropology, history, economics, and more. The book covers approaches to analysis ranging from interpersonal exchanges to world-historical changes - economic, political, and social. He shows how a thoroughgoing relational account of social processes, coupled with the careful identification of causal mechanisms, illuminates variation and change in the ways people live at the small scale and the large."
