The aim of this article is to question the nature of the socio-anthropological approach in Lefort’s thought. The author explores the complex relationship between Lefort and the Durkheimian French school of sociology in four stages: in the first, he shows Lefort as a sociologist ‘worthy of its name’ or, in other words, a sociologist interested in questioning the ‘institution of the social’. In the second, he focuses on the disturbing elements that Lefort introduces: the political and the division into the (...) French sociological approach. In the third stage, he focuses his attention on the sociological approach in Lefort’s way of thinking about democratic society. Finally, he concludes by referring to Lefort’s apparent opposition between philosophy and social sciences – and the errors that this may have engendered – in order to demonstrate the continuity of Lefort’s sociological approach.
