Abstract. The article is built on the principle of expanded paraphrase of philosophical treatise by Alain Badiou Rhapsodie pour le théâtre (Paris, 1990) that lays grounds for introducing an experimental form of new theatrical analytics. Beginning from the Modernism, culture reviews its own anthropological foundations: in the classical period, a human being was understood as the Apex of Creation while in the Post-Classical thought he becomes a Creator. The art of Modernism and the theatre in particular played a special role in development of a new understanding of a human. The author examines the evolution of the Avant-Garde theatre, the Post-Avant-Garde theatre, analyses and comments on the Alain Badiou’s work.
