Aristotle would not have been able to understand Aquinas’ ipsum esse subsistens. And he would not have been able to understand Aquinas’ assertion that the ipsum esse subsistens was the efficient cause of esse commune, i.e., the esse that belongs to beings which are “parts” of the cosmos ( “worldly beings”)
Certainly he would have, why not? A’s God had the same properties as T’s, therefore they are the same. The only difference is that A saw his God as a part of the universe, I think.
And he never considered a distinction between essence and existnece in things made of potency and act. Although that very concept should have given him pause, In fact the fact that in his God there was no potency was enough for A to call him he " whose very essence is actuality. " .
Aristotle’s unmoved mover is the most perfect being in the world (“perfect” because it has completely “actualized” its essence with no potentiality left unfullfilled) - but nonetheless it remains a part of the world. The esse of this most perfect being falls within the category of esse commune (“worldly esse”).
To our way of thinking you are correct. However that does not matter for the purposes of my argument. I have said, and continue to say that the two God’s had the same properties and therefore they were the same. You can’t blame A’s logic simply because he, apparently, knew nothing about a supernatural essence as such and that it could not be a part of the universe, unless placed there by God. He did not have the advantage of Divine Revelation. So while you are technically correct, you can’t fault A. or his God.
Aquinas’ ipsum esse subsistens is radically different from esse commune. It transcends the world completely. Such “esse” is not “esse” in the same sense as esse commune. It is not the esse of a being within the world (and this is the reason why Aquinas’ God is not one being among other beings).
Again I say that A did not know that, so you can’t blame his God. All I am saying is that when Thomas read A, he could not have missed the significance of what A said. What A said about potency and act and about his God who was pure act could well have been, and I maintain was, the source of T’s concepts of the distinction between essence and existence and a God who was simply Purus Subsistens Esse. A man ot T’s intelligence could not have missed the implications. .
Aristotle understood only esse commune, worldly esse. He would not have been able to understand the meaning of an “esse” that transcended the world.
Already addressed that.
Additionally, Aristotle would not have been able to understand an efficient cause of “esse”. His sense of efficient causality was limited to “motion”. You could say that Aristotle took “esse” for granted (like many others on this forum). “Esse” as such did not require an explanation because Aristotle did not know about the radical contingency of “esse commune”.
Why not? Esse is a perfection. Indeed, according to T, it is the perfection of perfections. And A certainly identified his God as the perfect Good, and One, both of which in T is the equivalent to Being and the True. Although, as far as I recall, he did not address an efficient cause of goodness in material beings. And that reminds me, A spoke of being as the first object of knowledge, the first thing in the world outside the mind of which we are aware ( Physics ). T certainly didn’t miss that. A’s whole Metaphysics was about
being qua being, things simply as existing. And here he is very close to T’s distinction between essence and the act of existence. And I contend that he failed to grasp the import of that idea because of his prior " prejudices, " he was a victum of his past philosophical culture.
And it is absolutely false that efficient causality was limited to motion, if by " motion " you mean local motion.
SAVED BY THE BELL, just caught your last post: " In the last paragraph of my previous posting (#48), I referred to Aristotle’s efficient causality as limited to “motion”. Of course, this “motion” is not just locomotion. The Greek word is closer to our English word, “change”. It could be a change in form, or a change in “accidents” (quality, quantity, or some other “accidental” change"). But most definitely it was a not a change from “nothing” to “esse”. Only Aquinas talks about this type of “existential” change.
That’s why the ipsum esse subsistens and its “efficient causality” of the “to be” or “esse” of things takes us way beyond Aristotle. "
O.K., you have advanced beyond the textbooks. Good for you.
And I agee A’s God was not developed fully as was T’s. I’m just saying that as far as he went, his God was the same as T’s. The interesting thing about A’s God and your last post is that oddly enough A’s God was the efficient cause of motion ( local motion ) only, it was not a " making or creating God " as far as I could tell.
And I agree that A had no concept of " esse commune. "
