Man is gifted with reason; he is life being aware of itself; he has awareness of himself, of his fellow man, of his past, and of the possibilities of his future. This awareness of himself as a separate entity, the awareness of his own short life span, of the fact that without his will he is born and against his will he dies, that he will die before those whom he loves, or they before him, the awareness of his aloneness and separateness, of his helplessness before the forces of nature and of society, all this makes his separate, disunited existence an unbearable prison. He would become insane could he not liberate himself from this prison and reach out, unite himself in some form or other with men, with the world outside.
