The following video illustrates a classic experiment that some say proves that materialism, the belief that matter is the fundamental reality, is false. The experiment is compatible with the view that mind is the most fundamental substance and that matter is a product of an observing mind.
One commenter at the Youtube site for this video asserts that all the theories seeking to explain the existence of the universe distill to three possibilities:
1. Either the universe(s) has always existed in one form or another and thus never needed creating because it always existed.
2. Or the universe(s) created itself from nothing where nothing previously existed.
3. Or that a divine entity has always existed and created it through an act of will.
He goes on to say that:
Each of these alternatives is equally outrageous and impossible to believe but one MUST be true. I like to think the first one is true.I don't think I agree that these are all equally hard to believe. I think the second is much harder to believe than the other two. Be that as it may, the commenter favors the first as a matter of metaphysical preference which is another way of saying that he doesn't really want a divine creator to exist.
Why he's averse to that alternative, he doesn't say, but I think a lot of people, whether theists or naturalists, share his basic outlook. What they believe about the universe, their fundamental worldview, is not a matter of logic or compelling reasons.
It's more a matter of taste, or subjective preference, or aesthetics, and it's very difficult, especially in this pragmatic, postmodern age, to persuade someone whose belief is based on a matter of personal preference to abandon it for the alternative.
