Rh 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?
