French novelist and philosopher Jean-Paul Sartre dies in Paris at the age of 74. Famous for his development and defense of atheistic existential philosophy, Jean-Paul Sartre was unusual in writing philosophy both for professional philosophers and for lay people.
He wrote typical philosophy books for the professional and for lay people he wrote novels and plays. All, though, expressed the same basic ideas. The central themes of Sartre's philosophy were "being" and "human beings." What does it mean to be? What does it mean to be a human being? Sartre argued that there are two kinds of being. First there being-in-itself (en-soi), which is characterized as fixed, complete, and having absolutely no reason for its being. It just is.
This is the same as the world of external objects. Second is being-for-itself (pour-soi), which means being dependent upon the former for its existence. It has no absolute, fixed, eternal nature. Thus, human existence is characterized by "nothingness" — anything which we claim is part of human life is of our own creation, often through the process of rebelling against external constraints.
