It seems to me that there is a fairly pervasive misunderstanding of these terms within our society. Here they are as I understand them to be: Theism: A belief in a god or gods. Atheism: A lack of belief in a god or gods. Agnosticism: A lack of certain knowledge regarding the existence of a god or gods - or, in some cases, the belief that knowledge of the existence of a god or gods is unattainable. If the above definitions are accurate, then one cannot simply describe themselves at "agnostic", they are either agnostic theists or agnostic atheists. What say you?
