The recent worldwide resurgence of militant nationalism, fundamentalist intolerance, and right-wing authoritarianism has again put the issues of violence and xenophobia at the center of social science research and theory. German psychoanalyst and sociolo gist Erich Fromm 's workprovides a useful theoretical microfoundationfor contemporary work on nationalism, the politics of identity, and the roots of war and violence. Fromm's analysis of Nazism in Escape from Freedom (1941), in particular, outlines a compelling theory of irrationality, and his later writings on nationalism provide an existential psychoanalysis that can he useful for contemporary social theory and sociology of emotions. Escape from Freedom synthesizes Marxist, Freudian, Weberian, and existen tialist insights to offer an original theoretical explanation of Nazism that combines both macrostructural and micropsychological levels of analysis. After forty-five years of research into the social origins offascism and with recent theorizing in the sociology ofnationalism and emotions, Escape from Freedom, its analysis ofNazism, and Fromm's larger theoretical perspective are worth reconsidering. The recent worldwide resurgence of militant nationalism, fundamentalist intolerance, and right-wing authoritarianism has again put violence and xenophobia at the center of social science research and theory (Calhoun 1994). Attempts to understand these diverse social phenomena must be grounded, of course, in concrete analysis of the history, politics, and social structure of specific nations. Sociologists increasingly recognize the need to analyze the emotional dynamics of irrationality, destructiveness, vengeance, and rage. Yet we do not have an adequate sociologically informed theory of emotions. The work of German psychoanalyst and sociologist Erich Fromm provides a useful theoretical microfoundation for contemporary work on nationalism, the politics of identity, and the roots of war and violence. Yet Fromm has long been unfashionable among social theorists even though his concern with Nazism, extreme nationalism, and authoritarianism has never been more relevant. From the early 1930s through the early 1960s, Fromm was a major social theorist associated with the Frankfurt School for Social Research, neo-Freu dian psychoanalysis, critical sociology, and early New Left politics. By the late 1960s and early 1970s, however, Fromm's reputation had dramatically declined, and he was widely dismissed by radical intellectuals as the Norman Vincent Peale of the left, as Herbert Marcuse once polemicized (Marcuse 1955). Fromm's work was allegedly marred by what * Numerous scholars read and made suggestions on earlier versions of this paper. I would particularly like to thank
