CHAPTER X.
GOD KNOWS ALL THINGS PERFECTLY, AND ACTS OF HIS OWN WILL, AND NOT FROM
NATURAL NECESSITY.
It is clear, from what has been said, that God knows all things. We see in the natural order, that those beings that are capable of knowing have a larger and more capacious nature than those that have no cognitive faculty. For, not only do they know their own form, but, being of a nature superior to matter, their cognitive power is able to receive the forms of other things. Hence the cognition of every cognitive form is ample and perfect, in proportion as that form is superior to matter. God, then, being Pure Act, i.e., superior to all matter and all potentiality, must possess the highest degree of cognisance, and the most complete understanding of all things.
God does not understand as men understand, i.e., by receiving the likeness of things into His understanding. For, being Simple Substance, His wisdom and His understanding are His nature; and, being wisdom itself He knows all things of Himself. And, since the power of God is nought but God Himself, and He is likewise wisdom itself, His wisdom must comprehend His power; and as His power is infinite, His wisdom must alike be infinite.
Some men entertain the foolish opinion that God knows superterrestrial things determinately, but that His knowledge of earthly things is confused and general; in other words, that man knows more things, or has a more perfect knowledge of them, than has God. Yet, even in merely natural things, the greater and more perfect the power, the more things it embraces and penetrates; and the more elevated a human intellect, the greater is its range of understanding, and the more exquisite its subtlety. Since, then, the Divine understanding is supereminent, and infinitely perfect, it must necessarily penetrate all things to their innermost being. And, since it is Immutable and Eternal, it is necessary that it should have perfect knowledge, not only of all things past, present and future, but also of all those which might ever be called into being. Moreover, this knowledge has not only existed from all eternity, but continues in the present, and will endure for ever.
We must, further, affirm that God acts, not from necessity, but by His Understanding and Will. Nature acts in a certain order without understanding it; and, as there cannot be order without intelligence, the operations of nature must be governed by some superior intellect. Now, as the intellect which governs is higher than the nature which is governed, and as God is the First Principle of all things, it is evident that He must act, not by natural necessity, but by Understanding and Will.
That which acts by natural necessity is drawn by its nature to produce an effect as far as possible similar to itself. Now, as God is Infinite Power, He would, therefore, were He constrained by natural necessity to act, produce infinite things—which would be an impossibility. God produces things according as they exist in Himself as in their Cause. Even as a house exists in the mind of an architect who builds it by means of his intelligence and will, so God also creates all things by means of His Intelligence and Will.
