Atheism, the absence of belief in gods, is a comparatively late phenomenon in history.

If there is a god, the only genuine friend he has is an atheist. He does not blame him for anything.

Who knows the origin of religion? Certainly not the one who believes in it. Understanding and belief are quite antagonistic. The man who understands religion does not believe in it, the man who believes in it does not understand it.

If one believes in a god, one is a Theist. If one does not believe in a god, then one is an A-theist — he is without that belief. The distinction between atheism and theism is entirely, exclusively, that of whether one has or has not a belief in God.

The worst that one can say of the Christian clergyman today is that he actually believes what he teaches.

All my life I have made it a rule never to permit a religious man or woman take for granted that his or her religious beliefs deserved more consideration than non-religious beliefs or anti-religious ones. I never agree with that foolish statement that I ought to respect the views of others when I believe them to be wrong.

Regularity in Nature is not proof of the control of Nature by a Divine intelligence; it is rather the reverse. If something- call it matter, or ether, or x - exists, it must operate in accordance with its innate qualities; and so long as this x remains uncontrolled, its manifestations will continue unchallenged- in other words, there will be order. The same causes, the same results. That is the manifest signs of a natural order that knows nothing of God.
