Okay, say you are in your imaginary world and a star seemingly comes from nothing. You have your list of possible causes. The problem for you is that there is one pernicious item on that list that can never be crossed out: “the star was caused by an as of yet unknown cause.” So you always have that statement plus “the star was uncaused” and you cannot cross off the unknown cause item except by identifying a cause, which will force you to cross off “the star was uncaused.” So you haven’t imagined a world where the star was really uncaused, even though you claim to have so imagined one, just like if I claimed that I imagined a square-circle doesn’t mean I actually have done so just because I claimed that I did.
My magical list is also omniscient. it has no unknown causes. I should have mentioned that last time.
But besides this, I can just
declare the star to be uncaused in my imagination. If I ask you to imagine a rock, you do not have to wonder how you
know that the item is a rock, and not an alien in disguise, you know your imaginary rock is merely a rock because you say it is. Or suppose I tell you imagine sitting in a room with one-way glass on a wall such that you can’t see out but other people can see in. are there people on the other side of the imaginary glass in the imaginary room? The answer is that there are if you say there are, and there aren’t if you say there aren’t, because the room is imaginary. You don’t have to imagine leaving your chair and investigating the adjacent room to find out, you can *make *the answer whatever you want it to be. Likewise, I can imagine a star appearing in the middle of empty space, and simply declare it to have come into existence without cause, because it is an imaginary event.
But all this might be moot, since we seem to have come to an agreement on efficient causes anyway:
I suspect that you and I are not using the word “cause” the same way. I am using it in Aristotle’s sense, which includes material, formal, efficient, and final causes (or as Prof. Kreeft likes to call them, the four “becauses”, which does a better job of getting at the meaning). You are probably identifying “cause” with “efficient cause”, so you are probably right in saying that every non-God reality might not have an efficient cause, but that doesn’t exclude say a formal cause. I propose that we use the word “reason” instead since it is more understandable. For everything that exists, is there a sufficient reason why it exists?
I had to look up what you meant by the four becauses, but your suspicion is correct. I was talking about efficient cause. If you expand that to include all reasons, it is indeed more difficult to think of a violation of the principle of sufficient reason that could occur in reality.
but…
I think I can do it. Suppose I get a note from my future self saying, “correct horse battery staple” I then climb in my time machine and deliver the message to my past self, completing a time loop. The eerie truth is that in this scenario, there is no reason why the message says what it says and not something else. It just… does.
If the answer is no, then why do we look for reasons things exist? I don’t see how you can only selectively adhere to the principle of sufficient reason (PSR) since if you’ve abandoned PSR then one could always say that when you give a reason for something, you are not really giving a reason and that there is no reason for the thing you are attempting to explain. It just looks like there is one. This is the difficulty with calling your reason into question.
I don’t think whether a person adheres to PSR or not should affect whether or not that person accepts a claim. Doubting PSR simply means that you acknowledge the
possibility of brute facts. It does not mean saying that
everything that exists or occurs is a brute fact. denying a claim (such as PSR) does not automatically mean believing its opposite. A person could deny PSR and still accept valid reasons for things.
Now we’re getting somewhere more interesting.

Yes, I think that accepting pure actuality does not automatically commit you to accepting that pure actuality is supremely intelligent. I think that it ultimately does necessarily lead to that conclusion, but it is not obvious simply by accepting pure actuality. That is another discussion. But if what you are saying is true, then Hawking not only admits the reality of God (pure actuality, he apparently just has a phobia of the word “God”) but even admits the possibility of miracles, since this pure actuality can inject reality into a natural order from the outside. That’s all well and good but it is not “nothing coming from nothing.”
I think God is best
defined as “non-physical mind which is the reason the universe exists.” If this happens to be pure actuality, so be it, but pure actuality is not an
essential property of God, that is, we could imagine a “non-physical mind which is the reason the universe exists” that is not also pure actuality.
The issue seems to be that you are defining “nothing” as the reality or concept that has no definable nature. I suppose that applies to both “nothingness” and “pure actuality.”
I am simply saying that it is possible that nothingness is unstable. The “basic law” of reality might not be that objects in existence continue existing in their state unless acted upon, as we see in our universe, but rather that states and objects chaotically change unless something prevents them from doing so. What I mean by “pure actuality” is the state in which anything can and does come into existence, which in this view is nothingness.
