Plato: The Republic

4. BOOK IV (continued)

What do you mean?

I mean to say that in reality for a long time past we have been talking of justice, and have failed to recognise her.

I grow impatient at the length of your exordium.

Well then, tell me, I said, whether I am right or not: You remember the original principle which we were always laying down at the foundation of the State, that one man should practise one thing only, the thing to which his nature was best adapted;-- now justice is this principle or a part of it.

Yes, we often said that one man should do one thing only.

Further, we affirmed that justice was doing one's own business, and not being a busybody; we said so again and again, and many others have said the same to us.

Yes, we said so.

Then to do one's own business in a certain way may be assumed to be justice. Can you tell me whence I derive this inference?

I cannot, but I should like to be told.

Because I think that this is the only virtue which remains in the State when the other virtues of temperance and courage and wisdom are abstracted; and, that this is the ultimate cause and condition of the existence of all of them, and while remaining in them is also their preservative; and we were saying that if the three were discovered by us, justice would be the fourth or remaining one.

That follows of necessity.

If we are asked to determine which of these four qualities by its presence contributes most to the excellence of the State, whether the agreement of rulers and subjects, or the preservation in the soldiers of the opinion which the law ordains about the true nature of dangers, or wisdom and watchfulness in the rulers, or whether this other which I am mentioning, and which is found in children and women, slave and freeman, artisan, ruler, subject,--the quality, I mean, of every one doing his own work, and not being a busybody, would claim the palm--the question is not so easily answered.
