Is atheism a belief?

[Mister Agenda]

Agnostic atheist, gnostic atheist etc.. is very recently developed concept.

But lets ask a question. If atheists who know God doesn't exist and atheists who don't know if God doesn't exist, can be separated by the gnostic agnostic distinction.

What separates atheists who believe God  doesn't exist, and those who don't believe God exists? What term should people use when referring to those who believe God doesn't exist, from those who lack a belief one way or the other?

Previously this distinction was made between agnos"" ticism, and atheism. If the new conception was to provide further clarity it failed to do so.

Yeah, such a recent concept, that agnostic atheism.

"The atheist may however be, and not unfrequently is, an agnostic. There is an agnostic atheism or atheistic agnosticism, and the combination of atheism with agnosticism which may be so named is not an uncommon one."

"If a man has failed to find any good reason for believing that there is a God, it is perfectly natural and rational that he should not believe that there is a God; and if so, he is an atheist... if he goes farther, and, after an investigation into the nature and reach of human knowledge, ending in the conclusion that the existence of God is incapable of proof, cease to believe in it on the ground that he cannot know it to be true, he is an agnostic and also an atheist – an agnostic-atheist – an atheist because an agnostic... while, then, it is erroneous to identify agnosticism and atheism, it is equally erroneous so to separate them as if the one were exclusive of the other..."
--Robert Flint, Croall Lecture of 1887-1888, published in 1903 as 'Agnosticism'

Got it from looking up 'agnostic atheism' on Wikipedia. So much research it took to find the facts of the matter! And FYI, Ingersoll was saying basically the same thing in 1885. So VERY recent....
