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.
