BOOK IV. · 5

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.

Nor yet by reason of a knowledge which cultivates the earth; that would give the city the name of agricultural?

Yes.

Well, I said, and is there any knowledge in our recently-founded State among any of the citizens which advises, not about any particular thing in the State, but about the whole, and considers how a State can best deal with itself and with other States?

There certainly is.

And what is this knowledge, and among whom is it found? I asked.

It is the knowledge of the guardians, he replied, and is found among those whom we were just now describing as perfect guardians.

And what is the name which the city derives from the possession of this sort of knowledge?

The name of good in counsel and truly wise.

And will there be in our city more of these true guardians or more smiths?

The smiths, he replied, will be far more numerous.

Will not the guardians be the smallest of all the classes who receive a name from the profession of some kind of knowledge?
