According to this, then, those things which are essentially and truly divine are called simple, because in them quality and substance are identical, and because they are divine, or wise, or blessed in themselves, and without extraneous supplement. In Holy Scripture, it is true, the Spirit of wisdom is called "manifold" because it contains many things in it; but what it contains it also is, and it being one is all these things. For neither are there many wisdoms, but one, in which are untold and infinite treasures of things intellectual, wherein are all invisible and unchangeable reasons of things visible and changeable which were created by it. For God made nothing unwittingly; not even a human workman can be said to do so. But if He knew all that He made, He made only those things which He had known. Whence flows a very striking but true conclusion, that this world could not be known to us unless it existed, but could not have existed unless it had been known to God.
