| Some further thoughts: * There is a crucial assumption in the 5 proofs that I think is worth thinking about. Given that something exists (I, the world, causes, parts, etc), it follows that there must be a First Cause/God. Also given ex nihilo nihil fit, it follows that the First Cause has to be eternal. The debate then is about the rest of the qualities, which I'm distinguishing as impersonal vs personal. However, note that this reasoning relies on the apriori fact that the world exists, from which we (and the proofs) intuit the presence of a First Cause. This still does not answer the big question: why is there anything at all? [0] There could have been no world and even no First Cause. We can imagine that there would exist only logical possibilities but no ontological "existence". There would be just be Nothing. Yes, the First Cause is eternal. But why? How did the First Cause arise in the first place? I think it's a valid question but it's unclear what the answer could be. One possibility is that logical existence is all there is. [1] But in any case, the eternalism of the First Cause, as in the proofs, is contingent on cogito, ergo sum and is not a necessity beyond that. I find it an interesting realization. * I am curious what you exactly mean by "the whole determines the parts, not vice-versa". One reading of it clashes wildly with all of our scientific investigations. From being a civilization which attribute everything to Gods and angels--making the sun go around the sky and natural calamities and good luck and bad luck---we've managed to figure out that we don't need such an attribution. Simple rules can generate a lot of complexity. Thus emergence and not God is what makes the world go. But the above statement seems to bring those ancients ideas back somehow. What am I missing? Also, I think even granting PPC and that the whole determines the parts still does not prove will. God can still be bound by some underlying rules. I don't know if logic alone can lead us to God's free will, until we have some empirical proof such as God actually willing unicorns into existence instead of lions. Even for humans, just saying I have will ("I can will myself to fly but don't want to") doesn't really count until I show it. * I'd like to hear your thoughts on my earlier question. If Christianity were to be shown as "false" as the other religions, and thus no human religion can demonstrate divine providence, how much will your belief in a personal God remain? Just from the proofs, do you think you will still strongly take a loving caring God who actively created and sustains this universe to be true? Looking forward to hearing your thoughts when you have the time. [0] https://www.preposterousuniverse.com/podcast/2018/08/13/epis...

It is not logical to appeal to the laws of physics in order to undermine what I'm saying, since (to repeat myself) these are as contingent as anything else. We can conceive that the laws of physics might have been otherwise, that they might change at some point in the future, or that they might not govern every event in reality. These concepts are logically possible. So are multiverses where the laws of physics are different. Therefore, the laws of physics are contingent, not necessary like mathematics.
It therefore follows that, if the Proofs successfully establish the existence of the First Cause, then said Cause must be causing some concepts to exist, and not others. There is nothing in the concepts themselves that make one exist, and the other not-exist. Choice is the ability to bring about effect A xor effect B, where A and B contradict. Therefore there is something on the part of the Cause that is causing one to exist, and the other not. And this obviously implies will on the part of the Cause. (Again, Feser and I are talking about the First Cause causing existence from instant to instant; not about looking back in time to what brought the universe into existence in the first place.)
Obviously the natural sciences (physics, zoology, etc) give us true information about the lion. For example, part of the concept of being a lion is that it needs food to continue its existence; that it is made up of cells that behave in a certain way; etc etc. And the details of all this could fill libraries. This is uncontroversial. But the natural sciences cannot provide a complete explanation of the lion's existence and the unicorn's non-existence, because (among other reasons) the the natural sciencse themselves are one concept rather than another, and because the need for things to 'obey' the laws of natural sciences is itself a concept that exists, etc. So your reference to biology, zoology, etc, while true, does not undermine my point. It is an explanation -- thus far we agree -- but it is a partial explanation of existence, which can't explain why some concepts exist and not others.
As for reductionism, hopefully you're happy with my definition (that everything's behavior can be explained in terms of my constituent particles). In effect, this would mean that natural objects are like artifcats. Consider an artifact like a computer. It's possible to explain how a computer works by explaining the behavior of its component parts, and then referring to their arrangement. For example, copper behaves a certain way, the plastic in the PCB behaves a certain way, the silicon in the ICs behaves a certain way, the electrons passing through the copper, silicon, etc behave in a certain way, etc. And then these things are arranged in a particular structure, and the combined behavior of all the parts gives us a computer. Obviously the same is true for a car, or a house, or whatever artifact you care to list.
Reductionism basically says that natural objects are like this as well. But this is false. Consider water, made up of H and O. Now hydrogen is a gas at room temperature, it burns with an invisible flame, it combines with nitrogen to form ammonia, with carbon to form methane or any number of things, it has one electron 'orbiting' one proton, and so on. All these things are properties of hydrogen. It is by the existence of these properties that we know hydrogen is present. Now, obviously, none of these things are true for water: literally everything I've listed is false. Certainly, hydrogen is present as a part of water -- don't get me wrong! But everything indicating the presence of hydrogen ceases to exist once it becomes part of water: an entirely new set of contradictory properties take their place. The behavior of the hydrogen has changed completely. And the same is true for the oxygen. The behavior of water cannot be explained by considering the properties of hydrogen and of oxygen, and 'combining' them in the way we would to explain the behavior of an artifact. In an artifact, the parts are unchanged, they just happen to be arranged in a certain order. In a natural thing like H20, the parts are completely changed to adapt to the whole of which they are part. So an artifact is the sum of its parts, but a natural thing is not.
You can consider a similar thing with a lion. A lion's liver, or eye, or paw, only acts like a liver/eye/paw while it is part of the lion. If you tear it out, its behavior fundamentally changes (it stops being a liver and becomes a lump of rotting flesh). So similarly, a lion cannot be said to be the sum of its parts. Rather, its parts can only be understood in terms of the whole of which they are part.
Therefore, empirically, it is false to think of every natural thing as the sum of its parts. Rather, the parts are derivative of the complete object, which is fundamentally one object. This is true for molecules, rocks, plants, animals, and human beings, along with any number of other things.
That's one reason reductionism is false. A second is that reductionism says that objects like lions are nothing more than particles arranged in a certain way. But the only way it can define this 'certain way' is by referring to a real lion. Sure, it can describe the 'certain way' in great mathematical detail, but ultimately it will be describing a lion. Reductionism is therefore circular. The only way out is to say that the lion doesn't really exist, and that it's a concept that we 'impose' on the particles. But there's no good reason for thinking this, and obviously, claiming that lions don't really exist can lead you into some pretty weird and anti-rational territory :-)
Thirdly, there is no actual good reason for thinking that things are nothing more than the sum of their parts. The fact that one can explain a thing's behavior according to its parts in no way implies that it is 'nothing more' than those parts as they would exist separately from that thing. Methodological reductionism does not imply ontological reductionism.
> Just from the proofs, do you think you will still strongly take a loving caring God who actively created and sustains this universe to be true?
To answer very, very quickly: I'd believe in the qualities that Feser outlines. But not 'loving caring' in a personal way. Not in the sense that one would hope a good parent to be. Only in the sense that God wills that which is good for everything. We'd know of His existence, but He would be very distant and unknowable. The Trinity and the Incarnation are complete game-changers in this regard, which is why they are the absolute foundational teachings of Christianity :-)
