The Theatre of the Absurd (50's) draws on the existentialist writings of Jean Paul Sartre and Albert Camus. Camus adapted Dostoyevsky's The Possesed to the stage (1959). Mostly, his writing was concerned with the dilemma of individuals who believe that values are relative but who cannot live without moral commitment. Camus argues that humanity has to resign itself to recognizing that a fully satisfying rational explanation of the universe is beyond its reach; thus the world must ultimately be seen as absurd. The underpinnings of the Theatre of the Absurd are derived from these existentialist ideas that led to Absurdism. Absurdism teaches, much like Camus, that, that which cannot be justified in a rational manner is absurd. Since religion requires a "leap of faith"(Kierkegaard) it is absurd, just as life itself is absurd. Jean Paul Sartre described the human consciousness as facing an apparently absurd world - absurd because it finds itself at the crossroads of Being and Nothingness.
