“As we have seen, there is something that most Americans share with Osama bin Laden, the nineteen hijackers, and much of the Muslim world. We, too, cherish the idea that certain fantastic propositions can be believed without evidence. Such heroic acts of credulity are thought not only acceptable but redeeming ― even necessary.”

“Believing a given proposition is a matter of believing that it faithfully represents some state of the world, and this fact yields some immediate insights into the standards by which our beliefs should function. In particular, it reveals why we cannot help but value evidence and demand that propositions about the world logically cohere.”

“Nothing that a Christian and a Muslim can say to each other will render their beliefs mutually vulnerable to discourse, because the very tenets of their faith have immunized them against the power of conversation. Believing strongly, without evidence, they have kicked themselves loose of the world. It is therefore in the very nature of faith to serve as an impediment to further inquiry.”

“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.”

“People who harbor strong convictions without evidence belong at the margins of our societies, not in our halls of power. The only thing we should respect in a person’s faith is his desire for a better life in this world; we need never have respected his certainty that one awaits him in the next.”

“It is time we admitted, from kings and presidents on down, that there is no evidence that any of our books was authored by the Creator of the universe. The Bible, it seems certain, was the work of sand-strewn men and women who thought the earth was flat and for whom a wheelbarrow would have been a breathtaking example of emerging technology. To rely on such a document as the basis for our worldview-however heroic the efforts of redactors- is to repudiate two thousand years of civilizing insights that the human mind has only just begun to inscribe upon itself through secular politics and scientific culture. We will see that the greatest problem confronting civilization is not merely religious extremism: rather, it is the larger set of cultural and intellectual accommodations we have made to faith itself.”

“How is it that, in this one area of our lives [religion], we have convinced ourselves that our beliefs about the world can float entirely free of reason and evidence?”
