37. Flesh, you say, is made up of pollution itself. For, according to you, some portion of that divine part escapes in the eating of vegetables and fruits: it escapes while they undergo the infliction of rubbing, grinding, or cooking, as also of biting or chewing. It escapes, too, in all motions of animals, in the carriage of burdens, in exercise, in toil, or in any sort of action. It escapes, too, in our rest, when digestion is going on in the body by means of internal heat. And as the divine nature escapes in all these ways, some very unclean dregs remain, from which, in sexual intercourse, flesh is formed. These dregs, however, fly off, in the motions above mentioned, along with what is good in the soul; for though it is mostly, it is not entirely good. So, when the soul has left the flesh, the dregs are utterly filthy, and the soul of those who eat flesh is defiled.
