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.

The belief in God is not therefore based on the perception of design in nature. Belief in design in nature is based upon the belief in God. Things are as they are whether there is a God or not. Logically, to believe in design one must start with God. He, or it, is not a conclusion but a datum. You may begin by assuming a creator, and then say he did this or that; but you cannot logically say that because certain things exist, therefore there is a God who made them. God is an assumption, not a conclusion. And it is an assumption that explains nothing.

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

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.

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.

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.

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