SOCRATES: The beneficial are good, and the hurtful are evil?
CALLICLES: To be sure.
SOCRATES: And the beneficial are those which do some good, and the hurtful are those which do some evil?
CALLICLES: Yes.
SOCRATES: Take, for example, the bodily pleasures of eating and drinking, which we were just now mentioning—you mean to say that those which promote health, or any other bodily excellence, are good, and their opposites evil?
CALLICLES: Certainly.
SOCRATES: And in the same way there are good pains and there are evil pains?
CALLICLES: To be sure.
SOCRATES: And ought we not to choose and use the good pleasures and pains?
CALLICLES: Certainly.
