This is not really true. If we accept a Humean account of causality and say that effects merely follow causes in time but are not actually the result of said causes, then empirical science is in trouble. If we accept the Kantian notion that our minds are merely imposing categories of thought upon a reality that is unintelligible, then we have no real access to knowledge even within our own universe.
There are also genuine concerns about why things would be valid even within our universe if there were not deeper metaphysical principles at play. I dislike the Kalam, but if we toss out the Principle of Sufficient Reason and say that contingent things can come about uncaused, then why would this not be the case within our universe as well? If it's just by chance that our universe appears to exhibit regularities, then it could just as easily cease to exhibit them. We do need to take some principles deeper than our universe or they don't even work within our universe.
(Don't read this as an argument for God. We 13th century throwbacks do things very differently and it doesn't really match up very well.)
Great point. Though clearly someone reading this post has yet to take their first philosophy class and thinks your points "funny."
However,
Contingency sans PSR
Stephen Davis adopts a version of the argument from contingency that eliminates the need of anything like PSR.
So Leibniz's 17th century construction of that premise is excluded.
1) Anything that exists has an explanation of its existence, either in the necessity of its own nature or in an external cause [A version of PSR].
2) If the universe has an explanation of its existence, that explanation is God.
3) The universe exists.
4) Therefore, the universe has an explanation of its existence (from 1, 3)
5) Therefore, the explanation of the existence of the universe is God (from 2, 4)
No PSR problem.
Leibniz's question,"Why is there something rather than nothing, can not be claimed to be a brute fact since we have a reason to believe that "Out of nothing nothing comes." So once we have a proper understanding of our universe coming from no space, no matter, no energy, no laws of physics, no time, we know there is no causal entity that can cause this phenomenon. We have knowledge that there is no case of nothing causing something.
I assume you referred to 'Kalam' by mistake and meant Contingency.
Wait what? How do you get that when I claim X, the inference you should get from that is that X isnt true?
I make the claim because I think the claim is true.
(Or maybe this universe is in fact a bit less intelligible than I'd thought.)
Ohhh. You changed emissary prof to chemistry prof.
I was thinking maybe you have friends in the BYU missionary studies dept or something.
lol. No BYU missionary professors. Just typing too quickly for keypad.
As to your inference about claims around empiricism let me try and clear up what I'm taking about.
My claim is one that is more foundational. It has nothing to do with empiricism per se but that it is inexplicable why we can understand our world at all, in order to a examine and collect data of a particular type, and b create inferences that possibly explain those data. We need an orderly world that is understandable to the senses and rationality. The atheist says of it "it is a brute fact and a happy accident."
The theist says it is designed to be perceived by human faculties.
So we would agree on empiricism but the story of why it is an accurate method would be grounded very differently.
Namely the problem is best described in the evolutionary argument against naturalism by Plantinga.
