SOCRATES: And what of your own art of husbandry, supposing that to have
supreme authority over the subject arts--what does that do? Does it not
supply us with the fruits of the earth?

CRITO: Yes.

SOCRATES: And what does the kingly art do when invested with supreme
power? Perhaps you may not be ready with an answer?

CRITO: Indeed I am not, Socrates.

SOCRATES: No more were we, Crito. But at any rate you know that if this
is the art which we were seeking, it ought to be useful.

CRITO: Certainly.

SOCRATES: And surely it ought to do us some good?

CRITO: Certainly, Socrates.

SOCRATES: And Cleinias and I had arrived at the conclusion that knowledge
of some kind is the only good.

CRITO: Yes, that was what you were saying.

SOCRATES: All the other results of politics, and they are many, as for
example, wealth, freedom, tranquillity, were neither good nor evil in
themselves; but the political science ought to make us wise, and impart
knowledge to us, if that is the science which is likely to do us good, and
make us happy.
