Some barbarians indeed poison their steel, but bravery has no need of gall, being dipped in reason, but rage and fury are not invincible but rotten. And so the Lacedaemonians by their pipes turn away the anger of their warriors, and sacrifice to the Muses before commencing battle, that reason may abide with them, and when they have routed a foe do not follow up the victory,[696] but relax their rage, which like small daggers they can easily take back. But anger kills myriads before it is glutted with revenge, as happened in the case of Cyrus and Pelopidas the Theban. But Agathocles bore mildly the revilings of those he was besieging, and when one of them cried out, "Potter, how are you going to get money to pay your mercenaries?" he replied laughingly, "Out of your town if I take it." And when some of those on the wall threw his ugliness into the teeth of Antigonus, he said to them, "I thought I was rather a handsome fellow." But after he had taken the town, he sold for slaves those that had flouted him, protesting that, if they insulted him again, he would bring the matter before their masters. I have noticed also that hunters and orators are very unsuccessful when they give way to anger.[697] And Aristotle tells us that the friends of Satyrus stopped up his ears with wax when he was to plead a cause, that he might not make any confusion in the case through rage at the abuse of his enemies. And does it not frequently happen with ourselves that a slave who has offended escapes punishment, because they abscond in fear of our threats and harsh words? What nurses then say to children, "Give up crying, and you shall have it," may usefully be applied to anger, thus, "Do not be in a hurry, or bawl out, or be vehement, and you will sooner and better get what you want." For a father, seeing his boy trying to cut or cleave something with a knife, takes the knife from him and does it himself: and similarly a person, taking revenge out of the hand of passion, does himself safely and usefully and without harm punish the person who deserves punishment, and not himself instead, as anger often does.
