Republic

By nature, they say, to commit injustice is a good and to suffer it is an evil, but that the excess of evil in being wronged is greater than the excess of good in doing wrong. So that when men do wrong and are wronged by one another and taste of both, those who lack the power to avoid the one and take the other determine that it is for their profit to make a compact with one another neither to commit nor to suffer injustice; and that this is the beginning of legislation and covenants between men, and that they name the commandment of the law the lawful and the just, and that this is the genesis and essential nature of justice—a compromise between the best, which is to do wrong with impunity, and the worst, which is to be wronged and be impotent to get one’s revenge. Justice, they tell us, being mid-way between the two, is accepted and approved, not as a real good, but as a thing honored in the lack of vigor to do injustice, since anyone who had the power to do it and was in reality a man would never make a compact with anybody either to wrong nor to be wronged; for he would be mad. The nature, then, of justice is this and such as this, Socrates, and such are the conditions in which it originates, according to the theory. But as for the second point, that those who practise it do so unwillingly and from want of power to commit injustice—we shall be most likely to apprehend that if we entertain some such supposition as this in thought: if we grant to each, the just and the unjust, licence and power to do whatever he pleases, and then accompany them in imagination and see whither his desire will conduct each. We should then catch the just man in the very act of resorting to the same conduct as the unjust man because of the self-advantage which every creature by its nature pursues as a good, while by the convention of law it is forcibly diverted to paying honor to equality. The licence that I mean would be most nearly such as would result from supposing them to have the power which men say once came to the ancestor of Gyges the Lydian. They relate that he was a shepherd in the service of the ruler at that time of Lydia, and that after a great deluge of rain and an earthquake the ground opened and a chasm appeared in the place where he was pasturing; and they say that he saw and wondered and went down into the chasm; and the story goes that he beheld other marvels there and a hollow bronze horse with little doors, and that he peeped in and saw a corpse within, as it seemed, of more than mortal stature, and that there was nothing else but a gold ring on its hand, which he took off and went forth. And when the shepherds held their customary assembly to make their monthly report to the king about the flocks, he also attended wearing the ring.
