More like a logical train wreck.
So we should believe in a god? Remember that this god has no explanation.
So unless you’ve misrepresented Aquinas, Aquinas is saying that if something can be explained, we should now believe in something that can’t be explained.
I don’t see any value there.
The value is in seeing the relative capabilities of your mind to know.
If God is omniscient, then he is completely knowable or comprehensible to Himself or any other intelligence with an infinite capacity to “know.” However, for human beings to know God would be sort of like, but infinitely more than, to use Peter Kreeft’s analogy, a slug trying to understand the mind of Einstein. To a slug, Einstein is incomprehensible, but to an intelligence capable of knowing Einstein, comprehensible.
Similar to this is our capacity to know God. He is incomprehensible to us, but comprehensible in Himself.
Our reason points us to its own limits. Knowing that we can only understand “to a certain limit” points in the direction of God being rationally knowable
if we had the capacity to do so.
This is a lesson about “our place” in creation. We are not all-knowing and sufficient unto ourselves to explain or understand all there is to know. In the final analysis God and creation are completely comprehensible, but not to human minds because of inherent limitations; in particular, that “information” must be “filtered” by limitations of our senses and processed by the limitations of our “reason.”
Do you believe yourself to be in possession of all knowledge? I assume the answer is “no.”
Do you believe your senses provide “full-disclosure” of everything going on around you? I assume the answer is no, again.
Do you believe your reasoning ability provides you with perfect understanding? Again, no. Right?
Therefore, some “things” about God and creation can be known by you, but His infinite intelligence is inexplicable and beyond you. Also, many things about creation cannot be known by you without some special arrangements by God to bring you to “know” fully.
