The article deals with Le Collège de Sociologie, an elective organization founded in 1937 by a group of French thinkers, among whom were Georges Bataille, Roger Caillois and Michel Leiris. It tries to show how the notion of `force' or of `power', constitutive to the `new mythology' the members of the Collège wanted to create, was in fact deeply ambivalent in nature. This ambivalence can be traced back to the internal ambiguities of the Durkheimian theory of the `collective effervescence', which (...) is shown to have influenced not only the collegians' notion of the sacred, but also their conception of power. This ambiguous theoretical heritage is curiously reflected in the conflicting conceptions Bataille and Caillois held of the notion of power — one of the major controversies, which later led to the dissolution of the Collège. The thesis defended here is that the seeds of this controversy lie already in the internal ambiguities of the Durkheimian theory and that these ambivalences were in a certain manner reproduced not only in the dispute between Caillois and Bataille, but also in much of the contemporary social theory drawing its inspiration from the Durkheimian sociology of the sacred.
