Belief. Knowledge. Agnosticism.

I do think it's possible to be a Gnostic Atheist, though the sound of it does bother me. It is perfectly possible to know that a god does not exist, as long as you are specific as to which god you are referring. For instance, certain Monotheistic gods (depending on which cult you are in) have one well known attribute. 'God is and always has been the the one and only god.' This is simply wrong, and CAN be disproven since those gods were originally Polytheistic.
