And we were saying, I believe, that the body being neither good nor evil, because of disease, that is to say because of evil, is the friend of medicine, and medicine is a good: and medicine has entered into this friendship for the sake of health, and health is a good.

True.

And is health a friend, or not a friend?

A friend.

And disease is an enemy?

Yes.

Then that which is neither good nor evil is the friend of the good because of the evil and hateful, and for the sake of the good and the friend?

Clearly.

Then the friend is a friend for the sake of the friend, and because of the enemy?

That is to be inferred.
