And that human virtue is justice?

To be sure.

Then men who are injured are of necessity made unjust?

Illustrations. But can the musician by his art make men unmusical?

Certainly not.

Or the horseman by his art make them bad horsemen?

Impossible.

And can the just by justice make men unjust, or speaking [D]generally, can the good by virtue make them bad?

Assuredly not.
