CRITIAS: Certainly I consider that those who have such wants are bad, and
that the greater their wants the worse they are.

SOCRATES: And do we think it possible that a thing should be useful for a
purpose unless we have need of it for that purpose?

CRITIAS: No.

SOCRATES: Then if these things are useful for supplying the needs of the
body, we must want them for that purpose?

CRITIAS: That is my opinion.

SOCRATES: And he to whom the greatest number of things are useful for his
purpose, will also want the greatest number of means of accomplishing it,
supposing that we necessarily feel the want of all useful things?

CRITIAS: It seems so.

SOCRATES: The argument proves then that he who has great riches has
likewise need of many things for the supply of the wants of the body; for
wealth appears useful towards that end. And the richest must be in the
worst condition, since they seem to be most in want of such things.
