First of all, you simply HAVE to have a world view (the lens) thru which you interact with everything and everyone around you.
And all the world views can be boiled down to three basic views:
Eastern...There is no personal God, what you see around you is an illusion and you strive to grow to and eventually lose yourself in becoming one with Nirvana/Shiva/Life Energy. Hinduism/Buddhism/New Age all fall under this. The concept of God is not one that is beyond the universe but IS the universe.
Western...a single personal God. Judaism, Christianity, Islam all fall under this. God is above and beyond the universe and created it all.
Atheism...there is no God, we are on our own, just candles in the wind that get snuffed out at the end. Atheism/Materialism/Naturalism...all fall under this. Morality is a human invented thing so the statements Hitler killed three million jews and it rained last night mean the same....because it all doesn't really matter if we just....snuff out.
As I see it, an Agnostic is someone who won't claim any world view is valid....that isn't a belief; it's simply ignoring the whole thing. So the default view for an agnostic is probably Materialism (atheism).
As an agnostic, it is tough trying to balance "on the fence". Trust me, I know as I was one for years. But....ya gotta choose...ignoring it is ignoring one of life's great questions and challanges....so come on, jump off the fence and do the soul searching and reading to find your way. Come on in, the water's great...
And you're right, this probably should not be in the new driver area. But it was fun to respond to....sorry bout the long winded post.
