For neither are knee and leg, and such other members, nor are the names applied to them, and the activity put forth by them, obscene. And even the secret parts of man are to be regarded as objects suggestive of modesty, not shame. It is their unlawful activity that is shameful, and deserving ignominy, and reproach, and punishment. For the only thing that is in reality shameful is wickedness, and what is done through it. In accordance with these remarks, conversation about deeds of wickedness is appropriately termed filthy [shameful] speaking, as talk about adultery and pæderasty and the like. Frivolous prating, too, is to be put to silence. “For,” it is said, “in much speaking thou shalt not escape sin.” “Sins of the tongue, therefore, shall be punished.” “There is he who is silent, and is found wise; and there is that is hated for much speech.” But still more, the prater makes himself the object of disgust. “For he that multiplieth speech abominates his own soul.”
