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? Wanna kill these ads? We can help!
