But I’m not suspending it arbitrarily, and I’m honestly surprised you can’t come up with the clear distinction between the case of “reason for the universe” and “reasons within the universe” on your own. There pretty obvious reasons why we might want to suspend our demand for reasons why.
“I’m not suspending it arbitrarily…” but “…we might want to suspend our demand for reasons why…” on “pretty obvious reasons.”
What precisely are those “pretty obvious reasons?”
You seem to refer to two.
- Reasons “why” are reasons from within the universe.
That doesn’t amount to a warranted reason for suspending our “demand for reasons” with reference to things outside the universe, merely that the universe itself is an internally coherent whole. Why should that be? Well all that integral coherency just “popped” into existence, I suppose, for no reason. You can’t say, however, that the internal coherency of the universe gives NO REASON for expecting reasonableness or explanations to proceed beyond the universe.
On balance it gives us more reason to expect reasons beyond the universe than not expect them, so your argument fails to support a contention that we have warrant for suspending our expectation for reasons existing beyond the bounds of the universe. You have given no warrant for that.
All our experiences of “reasons why” come from the latter camp: all the “reasons why” we’ve ever observed fall squarely into “reasons within the universe.” Inside the universe we have an arrow of time. We have laws of physics. These are the factors which lead people to a PSR in the first place. They are reasons why we would expect reasons why; reasons why it is reasonable to expect reasons why inside the universe. (Obviously, though, we can’t adhere to it so closely that we reject the possibility of things like actually random events in quantum systems as a violation.)
- Your second point is that we can’t (or very likely can’t) come to know what is beyond the universe, so we have no sufficient warrant for thinking reasons do exist outside of what we can know. This point is simply a non sequitur. What we don’t or can’t know does not serve to prove anything about what we don’t or can’t know.
Ignorance doesn’t provide warrant for anything regarding knowledge. In effect, ignorance doesn’t even tell you what you do know because you have to have at least an inkling of what you don’t know in order to know you are ignorant. Socrates made this point a long time ago - at least he knew that he didn’t know which put him a level above the truly ignorant.
Unfortunately, we really have very little knowledge that would allow us to talk about whatever framework the universe itself is embedded in. No arrow of time? No laws of physics? Why should we extend our inductive basis for the PSR this far? We have lost the reasons for expecting reasons why. Obviously cosmologists are trying to describe the framework but I believe that most are somewhat pessimistic, admitting that their theories are not likely to ever come into contact with hard scientific evidence (or at least, not in a conclusive way.)
You could only conclude THAT, if you dismiss revelation, in principle, as false. In other words, if God, as intentional Being “fills in” what we cannot access via our faculties alone by revealing what is “outside of the universe,” then we DO have warrant to thinking those eternal reasons do exist.
The fact that the God of the OT spoke to and revealed to humanity his reasons, is evidence that the “external” recognized the limits of human reasoning BEFORE human reasoning formally or logically recognized its own limitations, thus preempting the very objection you are making.
The question you need to answer is why you would dismiss the “outside in” provision of reasons FROM God TO human beings, in principle. By your own admission you cannot know what reasons God could have so you have no grounds for disputing revelation in principle.
I am sure you can provide YOUR reasons for dismissing revelation, but I am equally certain those reasons would be tainted by self-interest or human perspective bias rather than based on pure reason.
Either way, you haven’t provided reasons for dismissing the possibility of “external to the universe explanations” existing. Nor have you given the slightest warrant for thinking the PSR may not extend beyond space-time. You have defined the limits of what can be known by unaided human reason based upon empirical data. Fair enough.
That doesn’t, however, mean a strong logical or metaphysical case could not be made for extending the PSR beyond empirical or inductive limits.
