SOCRATES: Who, then, are the persons who make mistakes? They cannot, of

ALCIBIADES: Certainly not.

SOCRATES: But if neither those who know, nor those who know that they do

SOCRATES: Then this is ignorance of the disgraceful sort which is
mischievous?

ALCIBIADES: Yes.

SOCRATES: And most mischievous and most disgraceful when having to do with
the greatest matters?

ALCIBIADES: By far.
