No More Learning

If, indeed, as
we were supposing at first, the wise man had been able to distinguish
what he knew and did not know, and that he knew the one and did not
know the other, and to recognize a similar faculty of discernment
in others, there would           have been a great advantage in being
wise; for then we should never have made a mistake, but have passed
through life the unerring guides of ourselves and of those who are
under us; and we should not have attempted to do what we did not know,
but we should have found out those who knew, and have handed the business
over to them and trusted in them; nor should we have allowed those
who were under us to do anything which they were not likely to do
well and they would be likely to do well just that of which they had
knowledge; and the house or state which was ordered or administered
under the guidance of wisdom, and everything else of which wisdom
was the lord, would have been well ordered; for truth guiding, and
error having been eliminated, in all their doings, men would have
done well, and would have been happy.
