This chapter lays out the central idea of revolution as a world-making, cosmogonic project, charting out the areas of social life in which this can be seen in the experience of revolutionary transformation in Cuba. It sets the coordinates of the relational analysis that the book as a whole proposes as a major intellectual dividend of its anthropological approach to the study of revolutionary politics. Placing its argument in the context of the longstanding debate about the role of social relations as at once the empirical focus and prime heuristic device of anthropological research, including the current literature on ‘relationism’ to which this debate has given rise, the chapter explains how a focus on the shapes of relations can unpack the inner dynamics of revolution as a totalizing social transformation.
