How could one who was undisciplined make others temperate? One can mention no study except philosophy that develops self-control. Certainly it teaches one to be above pleasure and greed, to admire thrift and to avoid extravagance; it trains one to have a sense of shame, and to control one's tongue, and it produces discipline, order, and courtesy, and in general what is fitting in action and in bearing. In an ordinary man when these qualities are present they give him dignity and self-command, but if they be present in a king they make him preeminently godlike and worthy of reverence.
