Atheism is a philosophical rather theological position wherein a person is completely against the belief of Theism i.e. the existence of God. Whereas agnostic is a doubt. It is a doubt on the existence as well as non-existence of GOD or any divine object. In one word the theory of Agnostic Atheism states that whatever the situation is either the existence of God is in question or even if there is any deity it is either unknowable for human or is scientifically unproven.

Something about the Agnostic Atheist
For an Agnostic atheist the topic of God is not of much concern yet more than what we can define as apathy. Primarily because it is an apatheist’s belief that talking about or related to deity is futile but not of a person who stands on the ground of agnostic atheism. What makes the logic complete is simply the concern that anything which we claim should be substantial enough to be proved by science. There must be logic as well as a good explanation behind it.

The Mid Wall
Agnostic atheism is also considered as the mid wall between theist and atheist. It is a state where neither we nor science can say Yes or No to any question related to a deity or divinity. At this point what matters is the reality. Agnosticism takes the matter of deity to the further level of science and intellect, where a person needs to be in his or her right state of mind and should respond to this matter with radical explanations.

An atheist will always say that he believes that there is no god, where an agnostic atheist will say that he is not sure whether there is any trail of the existence of god.

Why Agnosticism with Atheism
Now you may ask “why agnostic atheism is not concerned about the existence of god, when atheism is joined with agnosticism?”

The answer to this question is something that we all must have learned in our school days and that is adjective pull to the noun. In this case it is an atheism which is agnostic in nature. We could say that reasoning and science developed this philosophical state wherein the atheist starts discarding the topic related to god and divinity.

This is the main difference between the two terms and when they both are together they create a new state which is agnostic atheism. This definition and its use have nothing do to with any religion as it is purely a psychological and philosophical state of mind.

First Known Atheism
The first atheism, or not believing in theism or a divine deity. was prominent in early Hinduism, Buddhism and other religions not due to their disbelief in deities but their disbelief in one God, monotheism, who graced man with mercy, forgiveness and an eternal life. Even in early Christianity, devout Christians were declared atheists simply because they did not follow the pagan deities of the government, but instead believed in their one God and followed teachings of Christ as their Messiah. Socrates was considered atheistic but not for today’s reason. Socrates also refused to follow the government’s dictated deities. It was not until the 16th and 18th centuries in the Western world that atheism became known as not believing in any deity and disavowing monotheistic beliefs and tenets.

Implicit vs Explicit Atheism
Today atheism has two separate meanings, although the primary disclaimer of any God is true of both Implicit and Explicit Atheism.

Implicit Atheism refers to the lack of belief in God simply because the individual never was presented with any of the beliefs or reasons for prayer or articles of faith. This lack of belief is in our toddler children who do not disbelieve, but do not believe, either, because they have never yet been exposed to beliefs and explanations of the existence of God. It has also been found in rare tribes in primitive jungle locations where there was no belief in any deity whatsoever, not any disbelief either, no rituals or ceremonies, and when a deceased member died, they were buried with no grieving attention later. They have never been exposed to beliefs in deities or the Western world’s monotheism so they have Implicit Atheism, like our small toddlers. No belief in God but not a disbelief in God.

Explicit Atheism is the disbelief of any God or other deity when the person has learned and understands the tenets and principles of a faith in God as creator and guardian of mankind’s souls; however, Explicit Atheists disdain and refuse to believe, follow nor even respect the belief. Theirs is an elementary stance that we cannot worship an unseen and judgmental God and especially tout that there are fallacies throughout all monotheistic beliefs in an intelligent design. “If God designed us, then who designed God?” is their most common deriding question and Explicit Atheism’s only benchmark.

Positive atheism (also known as strong atheism and hard atheism) asserts that no deities whatsoever exist. Most believe who subscribe to positive atheism will say gods do not exist. Negative atheism (also known as weak atheism and soft atheism) is defined as a person who does not believe in any deities but they have a lack of positive believe, meaning they do not believe strongly in either existence or nonexistence of a god.

In modern times, theism has been defined for the most part to mean a belief in a god who gives personal revelations to humans, and a belief in a personal god who takes an active interest in the world. Now in this case a positive atheist will assert that he does not believe that there is any god or gods and he is also the type of person who disbelieves in a personal being who is completely good and who created heaven and earth. On the other hand, the negative atheist would simply be the person without a belief in a personal god. Another way the differences between positive and negative atheism can be looked at is from the point of view of implicit and explicit atheism. The terms were coined by George H. Smith. Smith defined implicit atheism as “the absence of theistic belief without a conscious rejection of it”. He defined explicit atheism as “the absence of theistic belief due to a conscious rejection of it”. To put in more simple terms explicit atheists have rejected the idea that any belief in a deity existed when they considered it. Implicit atheists have either not given much thought to the ideas of deities, or though they do not believe in any deities, they have not rejected the possibility of belief.

The definitions of atheism can also be considered from a scientific point of view. A positive atheists would assert since humans live in a scientific world where the existence of things exist solely by their observability, a deity cannot exists since it cannot be observed. A negative atheist would assert since we have no proof of god, we cannot be sure one exists.
