Sociological interest in psychoanalytic thought, which began early in this century, has thus far emphasized the implications of Sigmund Freud's clinical discoveries. However, beginning in 1912, Freud produced a series of works which addressed social themes. These works included Totem and Taboo, Group Psychology and the Analysis of the Ego, The Future of an Illusion, Civilization and its Discontents, and Moses and Monotheism, as well as a number of papers dealing with social themes. This study began with a review of the social and intellectual influences on Freud's life and thought. Then a content analysis of Freud's social writings, identified above, was undertaken, to assess the significance for contemporary social theory of Freud's social thought. Categories for analysis were constructed: Society: Social Origins, Social Control and Social Change; Social Groups; the Family; Religion. Freud's ideas concerning these social categories and social institutions were explicated and an assessment of Freud as a social theorist was undertaken.
