"What is it all about?" Mitja (in Brothers Karamazov) felt that though his question may be absurd and senseless, yet he had to ask just that, and he had to ask it in just that way. Socrates claimed that an unexamined life is not worthy of man. And Aristotle saw Man's "proper" goal and "proper" limit in the right exercise of those faculties which are uniquely human. It is commonplace that men, unlike other living organisms, are not equipped with built-in mechanisms for automatic maintenance of their existence. Man would perish immediately if he were to respond to his environment exclusively in terms of unlearned biologically inherited forms of behaviour. In order to survive at all, the human being must discover how various things around him and in him operate. And the place he occupies in the present scheme of organic creation is the consequence of having learned how to exploit his intellectual capacities for such discoveries. Hence, more human than any other human endeavour is the attempt at a total view of Man's function— or malfunction—in the Universe, his possible place and importance in the widest conceivable cosmic scheme. In other words it is the attempt to answer, or at least articulate whatever questions are entailed in the dying groan of ontological despair: what is it all about? This may well prove biologically harmful or even fatal to Man. Intellectual honesty and Man's high spiritual demands for order and meaning, may drive Man to the deepest antipathy to life and necessitate, as one existentialist chooses to express it: "a no to this wild, banal, grotesque and loathsome carnival in the world’s graveyard."
