I’m no expert in Thomism. I can appreciate his insights into God, especially with regards to essence and existence being one in God. And he’s practically one of the most brilliant theologians ever. But I do think we make the mistake of canonizing (in a sense) Thomas Aquinas as THE Catholic perspective.
I can agree with that. Something I think is wise is to be intimately familiar with required Church Dogma and with the dynamics of logic/reason BEFORE reading Philosophers, especially (though not exclusively) great Catholic Philosophers. Often, we are sympathetic and biased toward the first well-stacked and well-argued position we encounter, so if we had encountered that position
before knowing all the facts to which it appeals, we can come to the automatic conclusion that those facts
necessarily mean that, when often the truth is that there are other possibilities, and the great thinker’s assertions were often
his (perhaps well-reasoned) conclusions, not infallibly exclusive proclamations that only heresy or flawed logic would disagree with.
If one encounters the admittedly impressive brilliance of an Aquinas or some other great thinker
before one’s orthodox faith and sense of reason is matured and adequately informed, it’s easy to be biased toward conflating those admittedly brilliant conclusions with utterly self-evident and irrefutable truths even though Catholics are under no compulsion to grant them such status. Basically, whoever makes the first good impression often enough “wins” and, while there IS no guaranteed way to avoid such biased blind spots, one might at least better guard against them by having had a mature and informed faith and sense of reason
before reading the philosopher in question, so that one can at least have greater confidence that the philosopher’s ideas truly
did seem compelling in context, rather than just making the first best impression so that now the individual scrambles to
make everything fit with that big thinker’s assertions.
In short, it must never be taken for granted that a philosopher’s thoughts (even a great Catholic thinker like Aquinas) WILL be true/correct, and one has no Catholic obligation to “make” things fit within a Thomistic framework, nor that of any other Philosopher. If it doesn’t seem to fit, one needn’t feel
pressure to
make it fit: One can simply disagree with the philosopher “in this case” (pending a different understanding of his words that may or may not become evident later) and move on.
