SOCRATES: And desire is of possession?
MENO: Yes, of possession.
SOCRATES: And does he think that the evils will do good to him who possesses them, or does he know that they will do him harm?
MENO: There are some who think that the evils will do them good, and others who know that they will do them harm.
SOCRATES: And, in your opinion, do those who think that they will do them good know that they are evils?
MENO: Certainly not.
SOCRATES: Is it not obvious that those who are ignorant of their nature do not desire them; but they desire what they suppose to be goods although they are really evils; and if they are mistaken and suppose the evils to be goods they really desire goods?
MENO: Yes, in that case.
SOCRATES: Well, and do those who, as you say, desire evils, and think that evils are hurtful to the possessor of them, know that they will be hurt by them?
MENO: They must know it.
