You know a successful method for discovering features of the world other than science!? Don’t hold back, what is the method and what features have you discovered?I did not point that out. The “features of the world” are not the same as the “features discovered by science” (though there may be overlap), not the least because science requires metaphysical and epistemic presuppositions that it does not internally justify. By “features of the world,” I simply mean things like the reality of change, the existence of contingent substances, etc.
Science is a method for distinguishing true statements about the universe from false ones, and it is true that there are possible statements science cannot prove. However, as far as I know, the only presuppositions science makes is that our sense data is reliable. We must not be receiving artificial signals like brains in vats and the universe must not have been created last Thursday. I have seen some people argue that science requires that the universe have laws and that those laws must not vary with space and time but that is incorrect. Those are assumptions many scientists make, but science would work even if they were not true.
Suppose we found that the best explanation for all the data we had was a model of an infinite-in-time universe which made it impossible for there to be an observer external to the universe (e.g. Relational quantum mechanics.) The theory might assert (for example) that the lack of observability implies that a thing must be uncaused, and therefore implies an uncaused universe. You could certainly could still postulate that there was some supernatural observer with Godlike properties, and science would be unable to prove or disprove it. However, it would add nothing to our actual understanding of the universe and could be safely kept in the closet with the “brain-in-a-vat” and “last Thursday” hypothesis.Even if that were true, science would certainly have no capacity to determine it. Empirical observation in principle cannot distinguish between a “brute fact” and an unobserved cause. (Even things like Bell’s theorem can’t demonstrate empirically that there are no hidden variables in quantum mechanics, for instance. For it would always be consistent to posit that every electron in the universe has been preordained to act in all of the ways that it does.)
I think this is a counterfactual hypothesis, anyway. Cosmological arguments (classically, at least) purport to be metaphysical demonstrations. They are not extraordinarily difficult to formulate validly. If their conclusions are false, then, it must be the case that one of the premises is false. But I think that there are at least a few variants of the cosmological argument that have true premises, so I don’t regard it as even epistemically possible that science should discover that the universe has no cause (even apart from the above considerations that such a discovery is not within science’s epistemic domains). (Barry Miller’s cosmological argument does not even rely on the principle of sufficient reason.)
Either the metaphysical demonstrations are based on a-priori reasoning, or they are statements based on some sort of empirical observation. If they are statements based on empirical observation, then they should be subject to scientific inquiry (unless you have some new and better method for distinguishing true statements from false ones based on empirical evidence.)
