SOCRATES: And they are not the same?

ALCIBIADES: Certainly not.

SOCRATES: Nor are there any who are in neither state?

ALCIBIADES: No.

SOCRATES: A man must either be sick or be well?

ALCIBIADES: That is my opinion.

SOCRATES: Very good: and do you think the same about discretion and want
of discretion?

ALCIBIADES: How do you mean?

SOCRATES: Do you believe that a man must be either in or out of his
senses; or is there some third or intermediate condition, in which he is
neither one nor the other?

ALCIBIADES: Decidedly not.

SOCRATES: He must be either sane or insane?

ALCIBIADES: So I suppose.

SOCRATES: Did you not acknowledge that madness was the opposite of
discretion?
