They have some actuality and some potency. They can learn, turn their attention, will this or that, act here or there, etc. but they cannot grow, decay, or lose form, because they have no matte
How does the idea that they have no matter but pure form not entail that matter is a kind of substrate of pure potentiality?
Likewise, wouldn’t there have to be some primitive constituent of matter that everything made of matter is comprised? Wouldn’t that primitive constituent be absolutely simple and thusly purely actual (along with God)?
For a similar example, there is the human soul, which is immaterial but subject to change, and informed by the body.
But I don’t think Aristotle believed this: this seems more of a Thomist thing. Aristotle just thought that the form of a living-being in virtue of which it is living and unified towards its natural end is the soul. It wasn’t some extra immaterial, cartesian-style thing infused with the body or informed by the body.
Aristotle is quite different in this regard because he hasn't separated out essence and existence. Aristotle complains about the notion of participation in the Metaphysics but Aquinas is able to plumb it more fully and make use of it.
Interesting. Can you elaborate more on this?
All creatures participate in God's being, which alone is subsistent.
To me, matter in the sense you described it threatens this very claim: matter would imply a basic constituent of material things which comprises them which, in turn, implies fundamental parts that are absolutely simple—they are pure potency infused in some kind of being that will receive the first form—and this would entail that there are multiple purely actual beings. What are you thoughts on that?
This is why I was thinking that composed beings must be infinitely divisible AND infused with being from God; because:
1. If a composed being is finitely divisible, then it’s fundamental part(s) are absolutely simple and two or more absolutely simple beings cannot exist; therefore, since God is absolutely simple every composed being must be infinitely divisible.
2. If composed beings are JUST infinitely divisible (viz., that explains the existence of each), then it wouldn’t exist because no member itself with have subsistent existence; therefore, God must be the first cause of the existence of the infinite chain of divisible parts of a given whole.
What do you think?
EDIT:
I am thinking of the chain of causality for a given object like this:
God → [..., parts of N - 1, parts of N, N]
I don't think it would be possible for:
God → first parts → ... → parts of N - 1 → parts of N → N
It would be impossible because the first parts would have to be absolutely simple because they are not made up of two or more parts: there would be nothing more fundamental to that contributes to the whole (of each first part) that isn't identical to it (viz., there would be no parts). Two or more absolutely simple beings cannot exist because they would be ontologically indistiguishable from each other. Therefore, since God is absolutely simple as subsistent being itself, it follows that this kind of causality would imply the contradiction of having at least two absolutely simple beings (namely God and the first parts).
What do you think?
