Aquinas, in his Summa, makes a series of assertion-of-fact about souls. Specifically, he claims that the soul explains (or "is the principle of") certain otherwise-unexplained phenomenon.
It doesn't matter how he got there (i.e. whether he was arguing with someone online, or trying to explain catholicism in terms of Aristotle, or if he was just an LLM stochastically putting ink on parchment), the fact is that inventing a supernatural thing that explains a bunch of unexplained phenomenon is precisely what I meant by "god-of-the-gaps style reasoning."
