We do not need the learned man to teach us the important things.  We all know the important things, though we all violate and neglect them.  Gigantic industry, abysmal knowledge, are needed for the discovery of the tiny things — the things that seem hardly worth the trouble.  Generally speaking, the ordinary man should be content with the terrible secret that men are men — which is another way of saying that they are brothers.
