And in another way too it is easy to stop the mouths of such men, for great is the abounding power of the truth. For wherefore dost thou never find fault with thy servant, because he is not of a beautiful countenance, that he is not of fine stature in his body, that he is not able to fly? Because these things are natural. So then from blame against his nature he is acquitted, and no man gainsays it. When therefore thou blamest, thou showest that the fault is not of nature but of his choice. For if in those things, which we do not blame, we bear witness that the whole is of nature, it is evident that where we reprove, we declare that the offense is of the choice.
