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

Religion is very enlightening - to those who don't understand it.

We cannot start with God and deduce the universe from his existence; we must start with the world as we know it, and deduce God from the world.

Worship God. It’s easier than thinking.

The devil and God are components of a Siamese twin. Neither has any existence apart from the other. In denying the existence of the one, Christians have helped to kill the other. If there need to be no fear of hell, people may well ask what is the attraction of heaven? Gods and devils were born together. Gods and devils will die together.

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.

It is useless saying that we do not accept the gods of the primitive world. In form, no; in essence, yes. The fact before us is that all ideas of gods can be traced to the earliest stages of human history.... There is an unbroken line of descent linking the gods of the most primitive peoples to those of modern man. We reject the world of the savage; but we still, in our churches, mosques, synagogues and temples, perpetuate the theories he built upon that world.
