Page 324 of Book X at paragraph 608 just before paragraph 609 and
further of course.
Plato: Are you not aware, I said, that the soul of man is immortal and
imperishable
Friend of Plato, Glaucon: He looked at me in astonishment, and said No,
by heaven: And are you really prepared to maintain this?
Plato: Yes, I said, I ought to be, and you too there is no difficulty in
proving it.
Friend of Plato, Glaucon: I see a great difficulty; but I should like to
hear you state this argument of which you make so light.
Plato: Listen then.
Friend of Plato, Glaucon: I am attending.
Plato: There is a thing which you call good and another whichyou call evil?
Friend of Plato, Glaucon: Yes, he replied.
Plato: Would you agree with me in thinking that the corrupting and destroying
element is the evil, and the saving and improving element the good?
Friend of Plato, Glaucon: Yes.
---And they

assumes immortality. Assume.
