Book excerpt: Alan Page Fiske shares insight on the basic models of social relations in this “important book that will be of value to all psychologists with an interest in organization, culture, economic behavior, and decision making” (Richard E. Nisbett, University of Michigan). Structures of Social Life examines the relational models of social relationships, including how they are implicit in earlier social theories, how they have emerged into diverse domains of social action and though, and how they produce diverse and complex social forms. Aiming to create conversations and debate about social relationships and the models that structure them, Alan Page Fiske provides insight on the four elementary forms of human relations.
