If, then, it was external to God, something else surely existed besides God, conceived, in respect of eternity, together with Him Who exists ungenerately; so that the argument supposes two eternal and unbegotten existences, having their being concurrently with each other—that of Him Who operates as an artificer, and that of the thing which admits this skilled operation; and if anyone under pressure of this argument should assume a material substratum for the Creator of all things, what a support will the Manichaean find for his special doctrine, who opposes by virtue of ungenerateness a material existence to a Good Being. Yet we do believe that all things are of God, as we hear the Scripture say so; and as to the question how they were in God, a question beyond our reason, we do not seek to pry into it, believing that all things are within the capacity of God’s power—both to give existence to what is not, and to implant qualities at His pleasure in what is.
Consequently, as we suppose the power of the Divine will to be a sufficient cause to the things that are, for their coming into existence out of nothing, so too we shall not repose our belief on anything beyond probability in referring the World-Reformation to the same power. Moreover, it might perhaps be possible, by some skill in the use of words, to persuade those who raise frivolous objections on the subject of matter not to think that they can make an unanswerable attack on our statement.
XXIV
An argument against those who say that matter is coeternal with God.123
For after all that opinion on the subject of matter does not turn out to be beyond what appears consistent, which declares that it has its existence from Him Who is intelligible and immaterial. For we shall find all matter to be composed of certain qualities, of which if it is divested it can, in itself, be by no means grasped by idea. Moreover in idea each kind of quality is separated from the substratum; but idea is an intellectual and not a corporeal method of examination. If, for instance, some animal or tree is presented to our notice, or any other of the things that have material existence, we perceive in our mental discussion of it many things concerning the substratum, the idea of each of which is clearly distinguished from the object we contemplate: for the idea of colour is one, of weight another; so again that of quantity and of such and such a peculiar quality of touch: for “softness,” and “two cubits long,” and the rest of the attributes we spoke of, are not connected in idea either with one another or with the body: each of them has conceived concerning it its own explanatory definition according to its being, having nothing in common with any other of the qualities that are contemplated in the substratum.
If,124 then, colour is a thing intelligible, and resistance also is intelligible, and so with quantity and the rest of the like properties, while if each of these should be withdrawn from the substratum, the whole idea of the body is dissolved; it would seem to follow that we may suppose the concurrence of those things, the absence of which we found to be a cause of the dissolution of the body, to produce the material nature: for as that is not a body which has not colour, and figure, and resistance, and extension, and weight, and the other properties, while each of these in its proper existence is found to be not the body but something else besides the body, so, conversely, whenever the specified attributes concur they produce bodily existence. Yet if the perception of these properties is a matter of intellect, and the Divinity is also intellectual in nature, there is no incongruity in supposing that these intellectual occasions for the genesis of bodies have their existence from the incorporeal nature, the intellectual nature on the one hand giving being to the intellectual potentialities, and the mutual concurrence of these bringing to its genesis the material nature.
Let this discussion, however, be by
