Social movements are social structures and not just sets of ideas. The three strands of any social movement can be reduced to variations on a structural feature of social movements. That feature is the role of the elite. Marxists wondered whether the vanguard served as educators of a working class destined to wrest history from the grasp of their oppressors, or as leadership cadres for democratic parties, or as the dictatorship of the proletariat. The psychoanalytic movement provides a similar trinity of roles for its elite, each of these anchored in one of the three strands a social movement generates.
