Plato in a myth puts the case even more strongly than this. Gyges, a shepherd and servant of the king of Lydia, found a gold ring which had the remarkable property of making its wearer visible when he turned the collet one way, and invisible when he turned it the other way. Being astonished at this, he made several trials of the ring, always with the same result; when he turned the collet inwards he became invisible, when outwards he reappeared. Perceiving this he immediately contrived to be chosen messenger to the court, where he no sooner arrived than he seduced the queen, and with her help conspired against the king and slew him, and took the kingdom. Plato asks us what we should do if we had such a ring. We could do anything we pleased and no one would be the wiser. We could become invisible, out of the reach of external consequences, the instant our deed was done. Would we, with such a ring on our finger, stand fast in righteousness? Could we trust ourselves to wear that ring night and day? Would we feel safe if we knew that our next-door neighbour, even our most intimate friend, had such a ring, and could do just what he pleased to us, and yet never get caught? Can we tell why a man with such a ring on his finger should not do any unjust, unkind, impure, or dishonourable deed? II RIGHTEOUSNESS WRIT LARGE The Republic is Plato's answer to this question. Why, you may ask, should he give us a treatise on politics in answer to a question of personal character? Because the state is simply the individual writ large, and as we can read large letters more easily than small letters, we shall get at the principle of righteousness more readily if we first consider what it is in the large letters of the state. In presenting this analogy of the state I shall freely translate Plato's teachings into their modern equivalent. What, then, is the difference between a righteous and unrighteous state?
