I haven't seen enough of the universe to feel confident that I'm correct in my atheism, and I haven't felt the hand of Nothing touch my heart and send me out to evangelize It.
Would you like a phrase to quickly and easily describe that state of being?
Apatheistic Agnostic. You're not concerned with the issue, it's too big and universal and we're too human. You're not convinced of anything, and frankly, since whatever does or doesn't come after this is inevitable and inescapable, what's the point of endless debate during our finite lives?
Who knows?... and who could even know? No one, that's who.
Actually I call myself an apathist among my friends. I don't care if there's a god, but if there is one, I doubt if it cares about me, and I doubt that it cares whether I believe in it or not.
How does this fit with the assertion that there is no evidence that the supernatural interacts with the natural in any measurable (and hence meaningful) way?
It seems related, but stronger:
"I don't know if there exists supernatural, however I have no reason to believe the supernatural will ever effect me."
You sort of have to come to that conclusion before you start down the apatheist road, I think. After all, any supernatural force that can predictably alter your world is going to rapidly become your god.
