[499d]
Socrates
Then are the beneficial ones good, and the harmful ones bad?
Callicles
Certainly.
Socrates
And are those beneficial which do some good, and those evil which do some evil?
Callicles
I agree.
Socrates
Now are these the sort you mean—for instance, in the body, the pleasures of eating and drinking that we mentioned a moment ago? Then the pleasures of this sort which produce health in the body, or strength, or any other bodily excellence,—are these good, and those which have the opposite effects, bad?
Callicles
Certainly.
