Similarly, it is the duty of the chief administrator of the laws, or the ruler of a state, to correct ill-disposed men, as long as he is able, with words, and even with gentle ones, that he may persuade them to do what they ought, inspire them with a love of honour and justice, and cause them to hate vice and set store upon virtue. He must then pass on to severer language, still confining himself to advising and reprimanding; last of all he must betake himself to punishments, yet still making them slight and temporary. He ought to assign extreme punishments only to extreme crimes, that no one may die unless it be even to the criminal’s own advantage that he should die. He will differ from the physician in one point alone; for whereas physicians render it easy to die for those to whom they cannot grant the boon of life, he will drive the condemned out of life with ignominy and disgrace, not because he takes pleasure in any man’s being punished, for the wise man is far from such inhuman ferocity, but that they may be a warning to all men, and that, since they would not be useful when alive, the State may at any rate profit by their death.
