SOCRATES: And are they wily, and do they deceive by reason of their
simplicity and folly, or by reason of their cunning and a certain sort of
prudence?

HIPPIAS: By reason of their cunning and prudence, most certainly.

SOCRATES: Then they are prudent, I suppose?

HIPPIAS: So they are--very.

SOCRATES: And if they are prudent, do they know or do they not know what
they do?

HIPPIAS: Of course, they know very well; and that is why they do mischief
to others.

SOCRATES: And having this knowledge, are they ignorant, or are they wise?

HIPPIAS: Wise, certainly; at least, in so far as they can deceive.

SOCRATES: Stop, and let us recall to mind what you are saying; are you not
saying that the false are powerful and prudent and knowing and wise in
those things about which they are false?

HIPPIAS: To be sure.

SOCRATES: And the true differ from the false--the true and the false are
the very opposite of each other?
