How's this for an assignment? It's a full sheet of paper (single spaced) all on its own!
"God understands himself through himself. In order to understand this, it should be known that [sc. in the operation of understanding]... the intelligible in act is the intellect in act. ... Therefore, since God has nothing of potentiality, but is pure act, it is necessary that in him the intellect and the thing understood should be the same in every way" (ST I 14.2).
"God, however, is pure act both in the order of existing things and in the order of intelligible things, and therefore he understands himself through himself" (ST I 14.2 ad 3).
In these lines, Aquinas describes the phenomenon of knowing as an identity in act of the knower (intellect) and the thing known (the intelligible). Departing from this description try to unfold what Aquinas says about the Creator's knowledge of himself and his creation:
1. Explain or describe the identity in act of intellect and intelligible. How does it relate to the description of truth? (i.e. relate it to the three descriptions of truth). Relate this understanding of truth analogously to God's self-understanding and to divine truth; negate the imperfection of created truth which is not found in the divine truth!
2. Which kind of being enables the intellect to become the other, i.e. to become informed by the "form" of the thing known? How would you relate intelligible being (ens intelligibile) to that which first falls in the intellect (ens universale)? Which relation between natural and intelligible being is found (1) in God and (b) in material things? Why would Aquinas say: "the object of the intellect is the first and primary principle in the genus of formal cause, for its object is being and truth … [and] under the truth [or intelligible being] are comprehended all apprehended forms"? (On Evil, q. 6; cf. SCG II, 98, n. 9: "the proper object of the intellect is intelligible being, which includes all possible differences and species of being"). Relate this to the description of the nature of being! Try to show that it is necessary to have a confused knowledge of the whole truth in order to know the limited participation of truth which is found in this or that thing (hint: the tree of Porphyrius).
3. This understanding of being enables Aquinas to describe God’s knowledge of the world / creation: Give a general account of God's knowledge of other things, especially with respect to the proper knowledge of everything. Try to say why the distinction of natural and intelligible being enables Aquinas to say that God is able to create (hint: On the Power of God 7.1 ad 8).
4. As a conclusion, describe the phenomenon of divine presentiality, i.e. that God is the presence of all things. Your discussion should include that there is no discursive thinking and no cause of the understanding of creatures in God (cf. 14.7; 19.5). The consequent distinction of presentiality from causality does not exclude that God perceives himself as principle of this world – why? Relate this distinction to the freedom of human beings!
