Many people make the great mistake of aiming directly at pleasure; they forget that pleasure comes only from the fulfillment of a duty or obedience to a law–for man is made to obey the laws of his nature as inescapably as he must obey the laws of gravity. A boy enjoys eating ice cream because he fulfills one of the “oughts” of human nature: eating. If he eats more ice cream than the laws of his body sanction, he will no longer get the pleasure he seeks but the pain of a stomachache. To seek pleasure, regardless of the law, is to miss it.
