Abstract
The paper deals with the Sartrean concept of lived experience which constitutes a bridge between phenomenology and Marxism, psychology and ontology, individual and society, as well as between philosophy and literary criticism. The notion of lived experience is rooted in psychology, at the same time being embedded in literary criticism and phenomenology. It is interlinked with the notions of facticity, contingency, singularity, intersubjectivity, and body in the Being and Nothingness, and became the theoretical base of Sartre’s essays on Baudelaire, Genet, and especially of that on Flaubert. This lived experience is closely related to the Sartrean phenomenological concept of nature which consists in the non-reflexive conscience of our own presence-at-theworld, including corporeality.
