I have something I call the "argument from existence" that is based on the fact that I am a conscious being and presumably you are all conscious beings too, and all of our individual consciousnesses are separate and discrete. I'm not convinced by any of the existing materialist theories of consciousness, and I can see how panpsychism would work with only one giant mind-meld consciousness, but not with separate discrete consciousnesses.
That is a very strong argument. It's actually my argument for why a purely materialistic account of reality is necessarily incomplete and why we must accept that there are such things as metaphysical truths independent of it (even if we have no access to those truths). It's not really an argument for God as such, though, at least not for all but the loosest definitions of God.
Yeah, of course it could be pure ~magic~, a simulation run by some entity in a world with different physics, or whatever. It simply requires there be some force beyond pure matter. I sometimes wonder if the simulation hypothesis grew out of attempts by materialists to grapple with the fact that there's nothing in the laws of physics that gives rise to consciousness and qualia.
Is there a name that people in the world of philosophy have for this argument? If there's any body of work on it I'm interested in reading more.
