STRANGER: To assume that one part of virtue differs in kind from another, is a position easily assailable by contentious disputants, who appeal to popular opinion.

YOUNG SOCRATES: I do not understand.

STRANGER: Let me put the matter in another way: I suppose that you would consider courage to be a part of virtue?

YOUNG SOCRATES: Certainly I should.

STRANGER: And you would think temperance to be different from courage; and likewise to be a part of virtue?

YOUNG SOCRATES: True.

STRANGER: I shall venture to put forward a strange theory about them.

YOUNG SOCRATES: What is it?

STRANGER: That they are two principles which thoroughly hate one another and are antagonistic throughout a great part of nature.

YOUNG SOCRATES: How singular!
