Max Weber is noted for his diagnosis of the rationalization of life under capitalism. But in his social thought he also developed a powerful theory of the process of 'sociation' and associational life. This paper investigates the latter aspect of his thought in the context of his and Marianne Weber's American journey. Their observations about the religious sects, the African-American community, educational insti tutions, and the position of women reveal an understanding of democ ratization as a process of voluntaristic sociation, (...) whose original model is the sect. In these institutional settings and through their interactions with figures like William James, W. E. B. Du Bois, and M. Carey Thomas, the Webers develop a view of American social life that empha sizes the contribution of associative activity to the moral and political education of individuals, and to the creation of a distinctively modern form of democratic culture.
