The man with the clear head is the man who frees himself from those fantastic "ideas" and looks life in the face, realises that everything in it is problematic, and feels himself lost. As this is the simple truth — that to live is to feel oneself lost — he who accepts it has already begun to find himself, to be on firm ground. Instinctively, as do the shipwrecked, he will look round for something to which to cling, and that tragic, ruthless glance, absolutely sincere, because it is a question of his salvation, will cause him to bring order into the chaos of his life.
