STRANGER: Let them say whether they would admit that there is such a thing as a mortal animal.
THEAETETUS: Of course they would.
STRANGER: And do they not acknowledge this to be a body having a soul?
THEAETETUS: Certainly they do.
STRANGER: Meaning to say that the soul is something which exists?
THEAETETUS: True.
STRANGER: And do they not say that one soul is just, and another unjust, and that one soul is wise, and another foolish?
THEAETETUS: Certainly.
STRANGER: And that the just and wise soul becomes just and wise by the possession of justice and wisdom, and the opposite under opposite circumstances?
THEAETETUS: Yes, they do.
