We have had any number of discussions on other threads that point out some of the “paradoxes” and “antinomies” that crop up when we apply metaphysical categories (e.g., substance, efficient causality) to God.
The reason for this is that God is “outside” the world yet metaphysical categories seem to be “world-dependent”. What I mean is that “time” is involved in their meaning. For instance, “substance” in Aristotle is governed by “presence” which is inescapably temporal (“presence” implies “past” and “future”). Likewise “efficient causality” is temporal, I.e., involves a “before” and “after” (and a “change” in the agent).
What brings all this to a head is the assertion (by Thomas Aquinas himself) that God does not have a “real” relation to the world although the world has a “real” relation to God. This move is necessary to safeguard God’s radical transcendence (that God does not need the world to be God).
But it also leads to “difficulties”.
For example, how can God be a substance without turning God into one entity alongside others?
I wonder whether you are sufficiently taking into account what Aquinas
himself says about the knowledge of God we can have in this life.
(1) About what we cannot know:
Some quotes from his writings . . .
“The most we can know of God during our present life is that He transcends everything that we can conceive of Him.” (
De Veritate, 2, 1 ad 9)
“For, by its immensity, the divine substance surpasses every form that our intellect reaches. Thus we are unable to apprehend it by knowing what it is. Yet we are able to have some kind of knowledge of it by knowing what it is not.” (
Summa Contra Gentiles, I, 14, 2) =
SCG
“We cannot grasp what God is, but only what He is not and how other things are related to Him.” (
SCG, I, 30, 4)
“Because we are not capable of knowing what God is but only what He is not, we cannot contemplate how God is but only how He is not” (
Summa Theologica, I, 3, Prologue) =
ST
“The reason why God has no name, or is said to be above being named, is because His essence is above all we understand about God and signify in word.” (
ST, I, 13, 1 ad 1)
“This is the ultimate in human knowledge of God: to know that we do not know Him.” (
Questiones Disputatiae de Potentia Dei, 7, 5, ad 14)
“In the end, we know God as unknown.” (
In Boetium de Trinitate, 1, 2, ad 1)
(2) Regarding what we can know and say:
What we predicate of God’s substance we do by
attributive analogy. I.e., we employ images and concepts derived from our experience of this world to help us know something about God’s nature. These are based on the meaning or content of the concept or image derived from our experience of creatures knowing God is their cause. God exists, is a person, is wise, good, love, truth, life, beautiful, just, merciful, etc. These tells us things about God that are real attributes.
B U T, these words, names, or concepts are predicated differently of God (as creator) versus things (as creatures). This is because our
mode of signification is based on experience of finite creatures (in time) and is therefore limited. So God is truly wise,
but not as we know wisdom. I.e., God is wise
in a way that is beyond what we can possibly imagine or conceive His wisdom to be.
We are UNABLE to attain:
comprehensive knowledge of God (to know God as fully as He is knowable) ever; or
essential (quidditative) knowledge of God (knowledge that would enable us define God or grasp His essential intelligibility as we would with the concept of “man” or “house”) in this life.
I would argue that if we consider what Aquinas himself taught, many of the problems you bring up are already dealt with or have their solutions intimated in his writings.
