I may have to read that chapter once more when I have time as it was rather difficult for me to comprehend (I am not a student of philosophy). But if you could elaborate on your second sentence and provide the logic behind the idea you express in your third sentence, I would have a better understanding. I do believe the chapter you linked to also explains what you have stated, but like I said, I need to reread it in hope of gaining a better understanding of St. Thomas’ arguments as presented by the author of the book.
Sonoran,
Thank you for your questions, and the way you’ve phrased them. I’ll be happy to answer them the best I can. I said the following
Exodus:
Free will, if it posits an uncaused cause, or the passing of potency to act without God as cause, is an incoherent concept.
To understand what this means, one must first understand a “law” of being, so to speak, which is this. No being passes from potency to act, except by some other being in act. The word potency here is used to refer to the “potential” state or mode of being that a given being has. A slab of marble, for instance, is potentially a statue, but only if a sculptor makes it such. The word act refers to a being in actuality, or its actual, current mode of being or existence. The slab of marble is actually a slab, for instance.
Now, this law of being applies to all levels of existence, whether spiritual/moral or physical. Further, by observing this law is how we can prove that God exists, and is a being with no potency. We can trace in the line of being, as it were, that all beings which receive the act that they have, depend on other beings in act, and so on. This cannot go on infinitely, else no being would ever receive act. There would be in infinitely regressive chain of causation (not in time, mind you, but logically or causally speaking) which would be infinitely insufficient in explaining how anything receives act. An infinite paintbrush does not give us a painter, just like an infinite amount of idiots do not give us an intelligent person. Eventually, we must posit a first cause which is uncaused, and, consequently, all act and no potency. This being does not “receive” existence in any way. It, rather, gives existence. This is what the Thomists mean when they say God is not determined BY creatures, but determines THEM.
Observing this fact, we can see that free choice or free will must have an explanation. Why one being chooses one act cannot be from the unmoved and uncaused will of the person alone, because we would then have an act - that is, the choice - which outside the scope of the divine causality and motion. Where could such an act receive its being? How could it pass from potency into act, unless it be moved to it? In short, if we posit a sort of “autonomous, spontaneous” freedom, we are positing an absurdity: an act without a cause, an uncaused act.
Further, if we draw this to its logical conclusion, we can see that God has either positively determined every good, or permitted every evil, logically speaking, prior to any act of any being whatsoever. He has done all this in such a way that is most wise, just, merciful and free. This is sometimes called “negative reprobation” and is thought to make God unjust, but the truth is that no creature, prior to it being in act, has any ontological status whatsoever. It is neither innocent, nor good (in which cases God would be unjust in allowing it to fail.) Rather, it is an uninstantiated substance or form, and, as such, deserves nothing from God, and has no “character” as it were. Yet God allows some forms or “vessels” to be defectible, or to fall back into nothing, which all beings are able and naturally tend to do, if they are not held in being at all times by God. God is not bound to keep defectible creatures from failing. If this were the case, no evil would ever occur. Rather, as said above, he allows or permits some to fail which, subsequently, makes them deserving of punishment. Again, it ought not to be thought of that God is letting an “innocent” or “naturally good” being fail, because, ontologically speaking, prior to God’s determination regarding said being, it has no “status” or “character.” It has not begun to change or experience any sort of movements, either good or evil.
Please let me know if you have any questions about the above.
