The paper outlines the theoretical and methodological complexity of the historical-philosophi- cal study of Georges Bataille’s literary and philosophical heritage, In: particular «Inner Expe- rience», one of his key works, which is about to be released in Ukrainian. To this end, I analyze the biographical and historical-philosophical contexts of writing «Inner Experience». I observe the main events of the thinker’s life, which led to the writing of this work and testify to Bataille’s opposition to the most common artistic movements of (...) the time (surrealism), philosophical theo- ries (existentialism), religious teachings, and, in fact, anti-systemic nature of his work. In addi- tion, the paper tends to identify sources of influence on the formation of philosophical views of Bataille in the period of «Inner Experience» writing. In particular, I analyze the theoretical and political relations of Bataille, especially with his critics (Belgian surrealists group, G. Marcel, J.-P. Sartre), but also allies (M. Blanchot, P. Klossowski, M. Leiris, H. Masson and others). Further, I study the genesis of the concept of «internal experience» formation, its inherent multi- faceted, multi-layered,and metaphorical nature, rooting in the tradition of Christian mysticism and reflecting the state after the loss of faith at the same time. Particularly, I study the image of the labyrinth as one of the most expressive synonyms of internal experience term, which empha- sizes the meaning of this fundamental word-concept of Bataille’s philosophy. To provide the in- tellectual context, I list main points of Bataille’s «Inner Experience» critique by representatives of the French intellectual communities of the 1940s, as well as the main Bataille’s arguments against this critique. Eventually, I analyze the main ideas of his «Inner Experience», as well as the ways how Bataille’s philosophy influenced the key representatives of the French poststruc- turalism (J. Derrida, M. Foucault, J. Kristeva, J.-F. Lyotard). (shrink)
