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

Gods are fragile things, they may be killed by a whiff of science or a dose of common sense.

It's usually easier to rouse stupidity to action than to arouse wisdom to effort, for wisdom sees alternatives while stupidity lacks the imagination to do this. All sinister interests in a country can depend ultimately upon the strength of stupidity.

Worship God. It’s easier than thinking.

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.

Human society is born in the shadow of religious fear, and in that stage the suppression of heresy is a sacred social duty. Then comes the rise of a priesthood, and the independent thinker is met with punishment in this world and the threat of eternal damnation hereafter. Even today it is from the religious side that the greatest danger to freedom of thought comes. Religion is the last thing that man will civilise.

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.
