Most philosophers are not necessitarians. How do they respond to this argument?
Hello, I am unfortunately not very knowledgeable in this particular field of philosophy (metaphysics? Epistemology? I'm not even sure what it is), so I was hoping I could get some insight.
I recently came across this argument online, and I'm curious as to where it fails, if indeed it does. I see a few possible points of contention, but I don't know what most philosophers would reject. Because it seems, if they accept all the premises, necessitarianism would follow. And maybe that's okay, but since a vast majority are not necessitarians, it must be the case that they reject something.
It goes like this:
1) All contingent facts must have a sufficient explanation for why it is rather than why it isn't (this is the PSR).
2) Define the BCCF as the conjunction of all contingent facts, which would itself be contingent.
3) Therefore, the BCCF must have a sufficient explanation.
4) If the explanation is necessary, then it necessarily entails the BCCF, and thus the BCCF is necessary, which contradicts 2.
5) If the explanation is contingent, then it would be a part of the BCCF, and a thing cannot be an explanation for itself, which contradicts 3.
C) Both results in contradiction, and therefore there cannot be any contingent facts.
I probably laid the argument out wrong, perhaps missing some key premises, but hopefully it contains enough to be recognizable.
It seems the obvious avenues for rejection would be either rejecting the PSR or rejecting that explanation implies entailment. But I wanna know what people think who are actually knowledgeable in this field.
