Man's ultimate concern must be expressed symbolically, because symbolic language alone is able to express the ultimate.
A man who has the courage of his platitudes is always a successful man. The instructed man is ashamed to pronounce in an orphic manner what everybody knows, and because he is silent people think he is making fun of them. They like a man who expresses their own superficial thoughts in a manner that appears to be profound. This enables them to feel that they are themselves profound.
