CRITO: Yes; that was the conclusion at which you had arrived, according to
your report of the conversation.

SOCRATES: And does the kingly art make men wise and good?

CRITO: Why not, Socrates?

SOCRATES: What, all men, and in every respect? and teach them all the
arts,--carpentering, and cobbling, and the rest of them?

CRITO: I think not, Socrates.

SOCRATES: But then what is this knowledge, and what are we to do with it?
For it is not the source of any works which are neither good nor evil, and
gives no knowledge, but the knowledge of itself; what then can it be, and
what are we to do with it? Shall we say, Crito, that it is the knowledge
by which we are to make other men good?

CRITO: By all means.

SOCRATES: And in what will they be good and useful? Shall we repeat that
they will make others good, and that these others will make others again,
without ever determining in what they are to be good; for we have put aside
the results of politics, as they are called. This is the old, old song
over again; and we are just as far as ever, if not farther, from the
knowledge of the art or science of happiness.

CRITO: Indeed, Socrates, you do appear to have got into a great
perplexity.
