I have never seen the slightest scientific proof of the religious ideas of heaven and hell, of future life for individuals, or of a personal God.

It does not seem to me that the evidence concerning the being of a God, and concerning immortality, is such as to enable us to assert anything in regard to either of these topics.

It is as impossible for man to demonstrate the existence of God as it would be for even Sherlock Holmes to demonstrate the existence of Arthur Conan Doyle.

I cannot believe in God when there is no scientific evidence for the existence of a supreme being and creator.

A god that does not manifest in reality is indistinguishable from a god that does not exist.

Religion has no warrant and no method for decreeing what is and what is not beyond science.

God does not exist—religion in science is an absurdity, in practice an immorality and in men a disease.

Just as there is nothing which resembles God,

Perhaps God—if there is one—doesn't care," Burton said. "There is no evidence whatsoever that He does.

The only excuse for God is that He does not exist.

God has no attributes.

When we claim that "God does not exist," we mean to deny by this declaration the personal God of theology, the God worshiped in various ways and divers modes by believers the world over, that God who from nothing created the universe, from chaos matter, that God of absurd attributes who is an affront to human reason.

God is an essence that we know nothing of. Until this awful blasphemy is got rid of, there never will be any liberal science in the world.

This I believe: I believe there is no god.
