SOCRATES: Then, if, as you would argue, not more painful, the evil of the soul is of all evils the most disgraceful; and the excess of disgrace must be caused by some preternatural greatness, or extraordinary hurtfulness of the evil.
POLUS: Clearly.
SOCRATES: And that which exceeds most in hurtfulness will be the greatest of evils?
POLUS: Yes.
SOCRATES: Then injustice and intemperance, and in general the depravity of the soul, are the greatest of evils?
POLUS: That is evident.
SOCRATES: Now, what art is there which delivers us from poverty? Does not the art of making money?
POLUS: Yes.
SOCRATES: And what art frees us from disease? Does not the art of medicine?
POLUS: Very true.
