That religion may have served some necessary function for us in the past does not preclude the possibility that it is now the greatest impediment to our building a global civilization.

Imagine a world in which generations of human beings come to believe that certain films were made by God or that specific software was coded by him.

And yet, this would be no more ridiculous than the world we are living in.

Religious faith is the only area of discourse where immunity through conversation is considered noble . It's the only area of our lives where someone can win points for saying, "There's nothing that you can do to change my mind and I'm taking no state of the world ultimately into account in believing what I believe.
