An atheist is someone who is certain that God doesn't exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.

An atheist is a man who has no invisible means of support.

To be an atheist is to maintain God. His existence or his non existence, it amounts to much the same, on the plane of proof. Thus proof is a word not often used among the Handdarata, who have chosen not to treat God as a fact, subject either to proof or to belief: and they have broken the circle, and go free.
To learn which questions are unanswerable, and not to answer them: this skill is most needful in times of stress and darkness.

Everybody is an atheist in saying that there is a god - from Ra to Shiva - in which he does not believe. All that the serious and objective atheist does is to take the next step and to say that there is just one more god to disbelieve in.

An atheist is a man who watches a Notre Dame - Southern Methodist University game and doesn't care who wins.

"No it's not!" said Constable Visit. "Atheism is a denial of a god."

"Therefore It Is A Religious Position," said Dorfl. "Indeed, A True Atheist Thinks Of The Gods Constantly, Albeit In Terms of Denial. Therefore, Atheism Is A Form Of Belief. If The Atheist Truly Did Not Believe, He Or She Would Not Bother To Deny."

Atheism is a non-prophet organization.

The philosophy of Atheism represents a concept of life without any metaphysical Beyond or Divine Regulator. It is the concept of an actual, real world with its liberating, expanding and beautifying possibilities, as against an unreal world, which, with its spirits, oracles, and mean contentment has kept humanity in helpless degradation.

He is an atheist who does not believe in himself. The old religions said that he was an atheist who did not believe in God. The new religion says that he is an atheist who does not believe in himself.

If you're an atheist, you know, you believe, this is the only life you're going to get. It's a precious life. It's a beautiful life. Its something we should live to the full, to the end of our days. Where if you're religious and you believe in another life somehow, that means you don't live this life to the full because you think you're going to get another one. That's an awfully negative way to live a life. Being a atheist frees you up to live this life properly, happily and fully

Atheism is a religion like not collecting stamps is a hobby.

The opposite of the religious fanatic is not the fanatical atheist but the gentle cynic who cares not whether there is a God or not. The atheist is a religious person. He believes in atheism as though it were a new religion.

"Atheism is not a philosophy; it is not even a view of the world; it is simply an admission of the obvious. In fact, "atheism" is a term that should not even exist. No one ever needs to identify himself as a "non-astrologer" or a "non-alchemist.

"If you describe yourself as "Atheist," some people will say, "Don't you mean 'Agnostic'?" I have to reply that I really do mean Atheist. I really do not believe that there is a god - in fact I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one. It's easier to say that I am a radical Atheist, just to signal that I really mean it, have thought about it a great deal, and that it's an opinion I hold seriously. It's funny how many people are genuinely surprised to hear a view expressed so strongly. In England we seem to have drifted from vague wishy-washy Anglicanism to vague wishy-washy Agnosticism - both of which I think betoken a desire not to have to think about things too much."
