Plato: The Republic

4. BOOK IV (continued)

Very good.

If there were four things, and we were searching for one of them, wherever it might be, the one sought for might be known to us from the first, and there would be no further trouble; or we might know the other three first, and then the fourth would clearly be the one left.

Very true, he said.

And is not a similar method to be pursued about the virtues, which are also four in number?

Clearly.

First among the virtues found in the State, wisdom comes into view, and in this I detect a certain peculiarity.

What is that?

The State which we have been describing is said to be wise as being good in counsel?

Very true.

And good counsel is clearly a kind of knowledge, for not by ignorance, but by knowledge, do men counsel well?

Clearly.

And the kinds of knowledge in a State are many and diverse?

Of course.

There is the knowledge of the carpenter; but is that the sort of knowledge which gives a city the title of wise and good in counsel?

Certainly not; that would only give a city the reputation of skill in carpentering.

Then a city is not to be called wise because possessing a knowledge which counsels for the best about wooden implements?

Certainly not.

Nor by reason of a knowledge which advises about brazen pots, I said, nor as possessing any other similar knowledge?

Not by reason of any of them, he said.
