This article analyses the worldview paradigm of Jean Paul Sartre and its relevance for the contemporary society. The article not only reminds the reader of the postulates of existential philosophy, but it also examines them in the context of time. The structure of J. P. Sartre’s concept of humanism is presented herein. Though humanism may be a universal category, in the thought of J. P. Sartre humanism contains his unique contribution. J. P. Sartre enthrones the human being by attributing freedom to the human. The human has possibilities to choose and must assume responsibility for the consequences. This freedom causes a great deal of anxiety, inevitably leaving the human alone – only with the opportunity, within the limits of his subjective capacity, to decide on the most important matter, himself. It is argued that the tendencies of philosophic discourse and the reality of development of society at this stage of evolution of mankind are such that humanism can be discovered and recognised only in contemplating J. P. Sartre’s existentialism. The relevance of Jean Paul Sartre is illustrated by the being of society. Society and the human being will inevitably try to escape the despair of subjectivity and by raising ontological issues, issues of universality of being.
