Sartre was the only self-declared existentialist among the major thinkers. For him the central idea of all existential thought is that existence precedes essence. For Sartre there is no God and therefore no fixed human nature that forces one to act. Man is totally free and entirely responsible for what he makes of himself. It is this freedom and responsibility that, as for Kierkegaard, is the source of man’s dread. Sartre’s thought, as expressed in his novels and plays as well as in his more formal philosophical writings, strongly influenced a current in French literature, best represented by Albert Camus and Simone de Beauvoir. In France the most prominent exponent of a Christian existentialism was Gabriel Marcel , who developed his philosophy within the framework of the Roman Catholic Church. Aside from Heidegger, the leading German existentialist was Karl Jaspers, who developed the central Kierkegaardian insight along less theological lines. Various other theologians and religious thinkers such as Karl Barth, Martin Buber, Paul Tillich, and Reinhold Niebuhr are often included within the orbit of existentialism.

But from another existential viewpoint (Kierkegaard’s), Linus’ faith in the Great Pumpkin is all that matters.
