Ask HN atheists & agnostics: Are you strictly materialist?
Or do you believe there may be more going on within our day to day realities than meets the eye, or that science hasn't detected yet?
However, I'm more interested in trying to be right tomorrow than I am to defending any given position that I hold today, so I'm not strictly anything. I.e.: http://www.paulgraham.com/identity.html
What I am though is a rationalist - i.e. I believe we use our minds a lot less efficiently then we could. We're starting this century to learn a lot about how the brain really works, and how reality really works - not at the basic levels but as very complex systems. And with this we slowly get pieces of how to be better humans. Ironically enough some of what we found is that religion/spirituality is a pretty good thing.
for tdoggette, you are wrong. There are many things that exist that are not part of material reality. My personal favorites are numbers. Particularly, the number two.
I used to think that letters also were not material, but then I saw a capital "I" on Sesame Street...
Isn't there some proof that it's impossible to fully explain a system (e.g. the universe) from within?
It is beyond my humble skills to suggest if the necessary formal description of the Universe would be complex enough for the incompleteness theorem to kick in or not. But bear in mind that explaining is not the same as proving. For instance, that the God created everything is a flawless explanation (although lacking in predictive strength to be of any use in sciences).
