Forms come by nature. Thomas says, “certain seeds of the sciences pre-exist in us, namely, the first conceptions of the intellect which are known right away by the light of the agent intellect through species abstracted from sensible things” (Thomas Aquinas: Selected Writings, Penguin Books., London 1998, p.198). The pre-existent seeds Thomas is referring to are those images which we passively receive by our senses and naturally actively abstract to some degree by way of our inherent agent intellect. Our agent intellect is created to function commensurately with our senses as it interacts with nature. The agent intellect is the active principle in our intellect that abstracts, or processes, all our sensory data, rendering them to our memories (passive intellect) for further consideration (if we want).

The notion that there can be a science of divine things does not negate Thomas’ statements regarding how we are unable to know the essence of God. A science of divine things is possible so long as we are clear regarding what we actually can and cannot know, and how the science of divine things proceeds.
First of all, only God can know his own essence. In fact, he knows himself “through his essence” (Thomas Aquinas: Selected Writings, Penguin Books., London 1998. p. 116). In other words, only God can truly know himself, as it is his essence to do so. The science of divine things must proceed from this basic understanding, namely, we cannot essentially know God. This does not mean, however, that we cannot in any way come to know God (as we will see).
Secondly, in terms of human reason, according to Thomas we can approach knowledge of God referring to the fact of his existence (and not of what he is). This can be done in three ways: 1) observing his effects in creation; 2) understanding his causality of “more noble effects” which grants a “better display of his eminence”, and; 3) in a negative sense we understand more clearly how he transcends all things and defies definition (Thomas quotes Dionysius, “he is known as the cause, the excess and negation of all things” – (Aquinas, Selected Writings, p. 117).
It is good and right to direct everything in our being towards God and union with him (including our intellects). However, errors are possible.
1) Presumption: in directing our intellect towards God we should not presume that we can comprehend God as we may be able to comprehend other aspects of creation (Thomas Aquinas, Thomas Aquinas Selected Writings, ed. by Ralph McInerny. Penguin Books: New York, 1998. p. 128).
2) Placing reason before faith in the directing of ourselves to God and to union with him. As God is incomprehensible to our intellects, and yet we are to direct everything towards him, we must “Begin by believing” (Aquinas, Selected Writings, p. 128). Believing is to hold something as real and true on the basis of what a knower tells us, so belief is the way we are able to transcend our intellects by receiving from God his self-revelation. This self-revelation is an outflow of God’s love towards us and thus the extent and form of his self-revelation is suited to our capacity. “Every creature is moved as to be made more and more like God insofar as it can be” (Aquinas, Selected Writings, p. 129). This movement happens through “infused faith” (Aquinas, Selected Writings, p. 131).
