I had gone with Glaucon to attend the celebration of the festival of Bendis—the Thracian Artemis—a picturesque affair, and we were just leaving, when Polemarchus insisted on carrying us off by main force to the house of his father, Cephalus. There we found a small company assembled. The old gentleman received us with hearty geniality; he is ageing, but would not see any hardship in that, if you take age good-humouredly. Of course, he owned that being wealthy makes a difference, but not all the difference. The best of wealth is that you need not do things which anger the gods and entail punishment in the hereafter; you need not lie, or be in debt to gods or men. And this consciousness of your own justice is a great consolation.
"But," said I, "what is justice? Is it always to speak the truth, and always to let a man have his property? There are circumstances——"
"I must go," said he. "Polemarchus shall do the arguing."
This set us discussing the nature of justice. Glaucon took up the cudgels, after a preliminary skirmish with Thrasymachus.
Assuming justice to be desirable—is it so for itself and by itself, or only for its results; or both? The world at large puts it in the second category as an inconvenient necessity. To suffer injustice is an evil, and to protect themselves from that the weak combine to prevent injustice from being done. But if anyone had the ring of Gyges, which made him invisible, so that he could go his own way without let or hindrance, he would get all the pleasures he could out of life without troubling about the justice of it. Again, imagine on the one hand your really consummate rogue who gets credit for all the virtues and is surrounded by all the material factors of happiness; and, on the other hand, a man of utter rectitude, on whom circumstances combine to fix the stigma of iniquity. He will be rejected, scourged, crucified; while the other is enjoying wealth, honour, everything, and can afford to make his peace with the gods into the bargain.
Then Adeimantus took the field in support of his brother. "The poets," he said, "hold forth about the rewards of virtue here and hereafter. But we see the unrighteous prospering mightily; and the religious mendicants come to rich folks and offer to sell them indulgences on easy terms. A keen-witted lad is bound to argue that it is only the appearance of justice that is needed for prosperity; while the gods can be reconciled cheaply. This dwelling on the temporal rewards of justice is fatal. What we expect of you is to show us the inherent value of justice—justice itself, not the appearance of it."
"Well argued," said I, "especially as you reject your own conclusion. I can but try, though the task be hard. But my weak sight may enable me to read large characters better than small. Justice is the virtue of the state as well as of the individual; finding it in the state, the greater, may help us to find it in the individual, the less."
II.—The Socratic Utopia
Society arises because different people are the better skilled to supply different wants, and the wants of each are supplied by mutual arrangement and division of labour. Wants multiply; the community grows; it exchanges its own foreign products; merchants and markets are added to the producers; and when folk begin to hire servants you have a complete city or state living a life of simplicity. "A city of pigs," said Glaucon, "with no refinements." We will go on and develop every luxury of civilisation. But then our city and its neighbours will be wanting each other's lands. We must have soldiers. Our best guardians will be a select band, those who are of the right temper and thoroughly trained; fierce to foes but gentle to friends, like that true philosopher, the dog, to whom knowledge is the test. The known are friends, the unknown foes—knowledge begets gentleness.
