True.

But neither can like be the friend of like, as we were just now saying.

True.

And if so, that which is neither good nor evil can have no friend which is neither good nor evil.

Clearly not.

Then the good alone is the friend of that only which is neither good nor evil.

That may be assumed to be certain.

And does not this seem to put us in the right way? Just remark, that the body which is in health requires neither medical nor any other aid, but is well enough; and the healthy man has no love of the physician, because he is in health.

He has none.

But the sick loves him, because he is sick?
