Must not injustice be a strife which arises among the three principles--a meddlesomeness, and interference, and rising up of a part of the soul against the whole, an assertion of unlawful authority, which is made by a rebellious subject against a true prince, of whom he is the natural vassal,--what is all this confusion and delusion but injustice, and intemperance and cowardice and ignorance, and every form of vice? Exactly so. And if the nature of justice and injustice be known, then the meaning of acting unjustly and being unjust, or, again, of acting justly, will also be perfectly clear? What do you mean? he said. Why, I said, they are like disease and health; being in the soul just what disease and health are in the body. How so? he said. Why, I said, that which is healthy causes health, and that which is unhealthy causes disease. Yes. And just actions cause justice, and unjust actions cause injustice? That is certain. And the creation of health is the institution of a natural order and government of one by another in the parts of the body; and the creation of disease is the production of a state of things at variance with this natural order? True. And is not the creation of justice the institution of a natural order and government of one by another in the parts of the soul, and the creation of injustice the production of a state of things at variance with the natural order? Exactly so, he said. Then virtue is the health and beauty and well-being of the soul, and vice the disease and weakness and deformity of the same? True. And do not good practices lead to virtue, and evil practices to vice? Assuredly. Still our old question of the comparative advantage of justice and injustice has not been answered: Which is the more profitable, to be just and act justly and practise virtue, whether seen or unseen of gods and men, or to be unjust and act unjustly, if only unpunished and unreformed? In my judgment, Socrates, the question has now become ridiculous. We know that, when the bodily constitution is gone, life is no longer endurable, though pampered with all kinds of meats and drinks, and having all wealth and all power; and shall we be told that when the very essence of the vital principle is undermined and corrupted, life is still worth having to a man, if only he be allowed to do whatever he likes with the single exception that he is not to acquire justice and virtue, or to escape from injustice and vice; assuming them both to be such as we have described? Yes, I said, the question is, as you say, ridiculous. Still, as we are near the spot at which we may see the truth in the clearest manner with our own eyes, let us not faint by the way. Certainly not, he replied. Come up hither, I said, and behold the various forms of vice, those of them, I mean, which are worth looking at. I am following you, he replied: proceed.
