I don't yet see how. Please elaborate, with direct reference to the OP if possible.
Because the OP is suffused with logic as the example of a brute fact. In addition to having offered 1) as a class of entity that provides further explanation, I've also provided criticism of your primary example, logic, and this serves to support 1) as well as inject doubt into the OP. Here are some examples from the text:
"One point following from this is that it is clearly impossible for everything to have an explanation, i.e. at some point explanation must bottom out with brute facts - those things for which not only no explanation is known, but for which no explanation exists to be discovered."
You've classified logic as a thing here by later referring to it as a brute fact. Hence my question as to its existence or not, and the subsequent dilemma.
"We might then ask what kind of things can qualify as brute facts, now that we are forced to concede their existence. Plausible candidates might be the fundamental laws of nature..."
I'm assuming by existence here you mean the BFs. Regardless, I'm again questioning how something that does not exist can serve as a brute fact, a stopping point, or anything else. And if the laws of logic do exist as abstract objects, you're wed to a highly contentious premise for your OP to be sound. It's reasonable doubt, at any rate.
"Simply put, explanation is data reduction - we understand things when we can subsume them under an existing law or principle, or contain them within some already established pattern."
Existing law? See above.
"The second point is that logic itself becomes a foundational stopping point for explanation. Logic is already as explained as anything can be..."
Is it? Again, I want to know if it
is a thing or not. This really makes a difference to whether it can
be a stopping point. It's as if we're saying no-thing can stop things.
"Now we draw a bunch of other circles outside of the first, each representing another consistent way that everything otherwise could have been."
Notice how the concept of being is used here. In these modal arguments, I still ask to know whether logic is thought to exist in these possible worlds.
"Most obviously, we cannot say that God caused the laws of logic."
How am I to think of causing something that doesn't exist?
Here it is again:
"To use the same modal concepts used above, to say that X is grounded in or depends upon Y is to say that in our circle (the actual world) we have both X and Y, that in at least one other circle there is no Y, and that in every circle where there is no Y there is also no X."
Now, in no way do I wish you to think I'm speaking poorly of this OP here. I think it's a fine, deep, and very interesting piece of work with lots of good elements that I'll take with me for future use. Hope you don't take my interaction with it any other way. The ontology quoted above, though, I believe to be an area of focus for you WRT the OP, even if it's merely a clarification of language. I'm arguing it's more, but I don't expect that to resonate with you, and that's okay, my friend.
