Chapter IX.—The Ridiculous Fancies of the Manichæans About the Motion of Matter Towards God; God the Author of the Rebellion of Matter in the Manichæan Sense; The Longing of Matter for Light and Brightness Good; Divine Good None the Less for Being Communicated. But in what manner, and from what cause, was matter brought to the region of God? for to it by nature belong the lower place and darkness, as they say; and the upper region and light are contrary to its nature. Wherefore there is then attributed to it a supernatural motion; and something of the same sort happens to it, as if a man were to throw a stone or a lump of earth up wards; in this way, the thing being raised a little by the force of the person throwing, when it has reached the upper regions, falls back again into the same place. Who, then, hath raised matter to the upper region? Of itself, indeed, and from itself, it would not be moved by that motion which belongs to it. It is necessary, then, that some force should be applied to it for it to be borne aloft, as with the stone and the lump of earth. But they leave nothing else to it but God. It is manifest, therefore, what follows from their argument. That God, according to them, by force and necessity, raised matter aloft to Himself. But if matter be evil, its desires are altogether evil. Now the desire of evil is evil, but the desire of good is altogether good. Since, then, matter has desired brightness and light, its desire is not a bad one; just as it is not bad for a man living in vice, afterwards to come to desire virtue. On the contrary, he is not guiltless who, being good, comes to desire what is evil. As if any one should say that God desires the evils which are attaching to matter. For the good things of God are not to be so esteemed as great wealth and large estates, and a large quantity of gold, a lesser portion of which remain with the owner, if one effect a transfer of them to another. But if an image of these things must be formed in the mind, I think one would adduce as examples wisdom and the sciences. As, therefore, neither wisdom suffers diminution nor science, and he who is endowed with these experiences no loss if another be made partaker of them; so, in the same way, it is contrary to reason to think that God grudges matter the desire of what is good; if, indeed, with them we allow that it desires it.
