ALCIBIADES: Why, Socrates, how is that possible? I must have been
mistaken.

SOCRATES: So it seems to me. But perhaps we may consider the matter
thus:--

ALCIBIADES: How?

SOCRATES: I will tell you. We think that some are sick; do we not?

ALCIBIADES: Yes.

SOCRATES: And must every sick person either have the gout, or be in a
fever, or suffer from ophthalmia? Or do you believe that a man may labour
under some other disease, even although he has none of these complaints?
Surely, they are not the only maladies which exist?

ALCIBIADES: Certainly not.

SOCRATES: And is every kind of ophthalmia a disease?

ALCIBIADES: Yes.

SOCRATES: And every disease ophthalmia?

ALCIBIADES: Surely not. But I scarcely understand what I mean myself.

SOCRATES: Perhaps, if you give me your best attention, 'two of us' looking
together, we may find what we seek.
