Agnostic atheism is a philosophical doctrine that encompasses both atheism and agnosticism.

"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." (p.49)
"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..."

An agnostic is a person who believes that the existence of a greater power, such as a god, cannot be proven or disproved; therefore an agnostic wallows in the complexity of the existence of higher beings.
Agnostics on religion (Christianity, Islam, Buddhists, etc): Religious zealots are often viewed as ignorant by agnostics because of their blind following of a supreme being which may or may not exist.
An agnostic views an atheist on the same plane as a religious zealot; often because the belief that human beings are the pinnacle of intelligence and there are few things that we do not or have the potential to understand.
Agnosticism is the philosophical and theological view that spiritual truths, such as the existence of God, gods or deities, is either unknown or inherently unknowable.
Agnosticism is not to be confused with a view specifically opposing the doctrine of gnosis and Gnosticism—these are religious concepts that are not generally related to agnosticism.
However, one can still draw a distinction between weak atheism and agnosticism by drawing a distinction between belief and knowledge, leading those who believe knowledge of God is not possible to claim agnosticism is about knowledge, while atheism/theism is about the lack of belief.
