NO ATOMIC AGGREGATION COULD PRODUCE A SELF-HARMONIZING UNITY.
3. (b.) (No aggregation of atoms could form a whole that would be one and sympathetic with itself.) Others, on the contrary, insist that the soul is constituted by the union of atoms or indivisibles (as thought Leucippus, Democritus and Epicurus.) To refute this error, we have to examine the nature of sympathy (or community of affection, a Stoic characteristic of a living being — Eneada-II, 3, 5) and juxtaposition (Eneada-II, 7, 1). On the one hand an aggregation of corporeal molecules which are incapable of being united, and which do not feel cannot form a single sympathetic whole such as is the soul, which is sympathetic with herself. On the other hand, how could a body or extension be constituted by (a juxtaposition of) atoms?
SOUL IS A SIMPLE SUBSTANCE, WHILE EVERY BODY IS COMPOSED OF MATTER AND FORM.
(c.) (Every body is a composite of matter and form, while the soul is a simple substance.) Inasmuch as matter possesses no quality (Eneada-II, 4, 7), the matter of no simple body will be said to possess life in itself. That which imparts life to it must then be its form. If form is a “being,” the soul cannot simultaneously be matter and form; it will be only matter or form. Consequently, the soul will not be the body, since the body is not constituted by matter exclusively, as could be proved analytically, if necessary.
IF SOUL IS ONLY AN AFFECTION OF MATTER, WHENCE THAT AFFECTION?
(d.) (The soul is not a simple manner of being of matter, because matter could not give itself a form.) Some Stoics might deny that form was a “being,” asserting the soul to be a mere affection (or, manner of being) of matter. From whence then did matter acquire this affection and animating life? Surely matter itself could not endow itself with a form and a soul. That which endows matter or any body with life must then be some principle alien and superior to corporeal nature.
NO BODY COULD SUBSIST WITHOUT THE POWER OF THE UNIVERSAL SOUL.
(e.) (No body could subsist without the power of the universal soul.) Besides no body could subsist without the power of the universal Soul (from Numenius), Every body, indeed, is in a perpetual flow and movement (as thought Heraclitus, in Plato, Cratylus), and the world would soon perish if it contained nothing but bodies, even if some one of them were to be called soul; for such a soul, being composed of the same matter as the other bodies, would undergo the same fate that they do; or rather, there would not even be any body, everything would remain in the condition of shapeless matter, since there would exist no principle to fashion it. Why, there would not even be any matter, and the universe would be annihilated to nothingness, if the care of keeping its parts united were entrusted to some body which would have nothing but the name of soul, as for instance, to air, or a breath without cohesion, which could not be one, by itself. As all bodies are divisible, if the universe depended on a body, it would be deprived of intelligence and given up to chance. How, indeed, could there be any order in a spirit which itself would need to receive order from a soul? How could this spirit contain reason and intelligence ? On the hypothesis of the existence of the soul, all these elements serve to constitute the body of the world, and of every animal, because all different bodies together work for the end of all; but without the soul, there is no order, and even nothing exists any more.
