“It is merely an accident of history that it is considered normal in our society to believe that the Creator of the universe can hear your thoughts while it is demonstrative of mental illness to believe that he is communicating with you by having the rain tap in Morse code on your bedroom window.”

“While believing strongly, without evidence, is considered a mark of madness or stupidity in any other area of our lives, faith in God still holds immense prestige in our society. Religion is the one area of our discourse where it is considered noble to pretend to be certain about things no human being could possibly be certain about. It is telling that this aura of nobility extends only to those faiths that still have many subscribers. Anyone caught worshipping Poseidon, even at sea, will be thought insane.”

“If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.”

“Imagine a world in which generations of human beings come to believe thatcertain films were made by God or that specific software was coded by him.Imagine a future in which millions of our descendants murder each otherover rival interpretations of Star Wars or Windows 98. Could anything --anything -- be more ridiculous? And yet, this would be no more ridiculousthan the world we are living in. ”

“It is time we realize that belief is not a private matter. As a man believes, so he will act. Believe that you are a member of a chosen people, awash in the salacious exports of an evil culture that is turning your children away from God, believe that you will be rewarded with an eternity of unimaginable delights by dealing death to these infidels—and flying a plane into a building is only a matter of being asked to do it.”

“[I]t is difficult to imagine a set of beliefs more suggestive of mental illness than those that lie at the heart of many of our religious traditions.”

“In the year 2006, a person can have sufficient intellectual and material resources to build a nuclear bomb and still believe that he will get seventy-two virgins in Paradise.”
