It's very difficult to say where I stand between agnosticism, atheism, and apatheism.
I don't know for certain that there is no god, though I consider it highly probable there is not one. In absence of evidence for anything so general, no less specific as rules about how to live ones life, I see no reason to live my life as a believer in any such thing.
Usually I call myself an agnostic atheist.
EDIT: Gnosticism should be on this list.
EDIT 2: Then again, I suppose Gnosticism in a generalized, non-Christian form my fall under transtheism.
