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!
