A wise one.

You think, I said, that to act with a wise man is more fortunate than to
act with an ignorant one?

He assented.

Then wisdom always makes men fortunate: for by wisdom no man would ever
err, and therefore he must act rightly and succeed, or his wisdom would be
wisdom no longer.

We contrived at last, somehow or other, to agree in a general conclusion,
that he who had wisdom had no need of fortune. I then recalled to his mind
the previous state of the question. You remember, I said, our making the
admission that we should be happy and fortunate if many good things were
present with us?

He assented.

And should we be happy by reason of the presence of good things, if they
profited us not, or if they profited us?

If they profited us, he said.

And would they profit us, if we only had them and did not use them? For
example, if we had a great deal of food and did not eat, or a great deal of
drink and did not drink, should we be profited?

Certainly not, he said.
