DIADUMENUS. Now the common conception of an element and principle, naturally imprinted in almost all men, is this, that it is simple, unmixed, and uncompounded. For that is not an element or principle which is mixed; but those things are so of which it is mixed. But these men, making God, who is the principle of all things, to be an intellectual body and a mind seated in matter, pronounce him to be neither simple nor uncompounded, but to be composed of and by another; matter being of itself indeed without reason and void of quality, and yet having simplicity and the property of a principle. If then God is not incorporeal and immaterial, he participates of matter as a principle. For if matter and reason are one and the same thing, they have not rightly defined matter to be reasonless; but if they are different things, then is God constituted of them both, and is not a simple, but compound thing, having to the intellectual taken the corporeal from matter.
