The Republic by Plato Part 4 Page 30

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.
