(11). (If, as Stoics claim, man first was a certain nature called habit,[70] then a soul, and last an intelligence, the perfect would have arisen from the imperfect, which is impossible). To say that the first nature of the soul is to be a spirit, and that this spirit became soul only after having been exposed to cold, and as it were became soaked by its contact, because the cold subtilized it;[71] this is an absurd hypothesis. Many animals are born in warm places, and do not have their soul exposed to action of cold. Under this hypothesis, the primary nature of the soul would have been made dependent on the concourse of exterior circumstances. The Stoics, therefore, posit as principle that which is less perfect (the soul), and trace it to a still less perfect earlier thing called habit (or form of inorganic things).[72] Intelligence, therefore, is posited in the last rank since it is alleged to be born of the soul, while, on the contrary, the first rank should be assigned to intelligence, the second to the soul, the third to nature, and, following natural order, consider that which is less perfect as the posterior element. In this system the divinity, by the mere fact of his possessing intelligence, is posterior and begotten, possessing only an incidental intelligence. The result would, therefore, be that there was neither soul, nor intelligence, nor divinity; for never can that which is potential pass to the condition of actualization, without the prior existence of some actualized principle. If what is potential were to transform itself into actualization--which is absurd--its passage into actualization will have to involve at the very least a contemplation of something which is not merely potential, but actualized. Nevertheless, on the hypothesis that what is potential can permanently remain identical, it will of itself pass into actualization, and will be superior to the being which is potential only because it will be the object of the aspiration of such a being. We must, therefore, assign the first rank to the being that has a perfect and incorporeal nature, which is always in actualization. Thus intelligence and soul are prior to nature; the soul, therefore, is not a spirit, and consequently no body. Other reasons for the incorporeality of the soul have been advanced; but the above suffices (as thought Aristotle).[73] II. THE SOUL IS NEITHER THE HARMONY NOR ENTELECHY OF THE BODY--THE SOUL IS THE HARMONY OF THE BODY; AGAINST THE PYTHAGOREANS.
