“We can either have a twenty-first-century conversation about morality and the human well-being - a conversation in which we avail ourselves of all scientific insights and philosophical arguments that have accumulated in the last two thousand years of human discourse - or we can confine ourselves to a first-century conversation as it is preserved in the Bible.”

“We have a choice. We have two options as human beings. We have a choice between conversation and war. That's it. Conversation and violence. And faith is a conversation stopper.”

“our moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy.”

“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.”

“The only thing that guarantees an open-ended collaboration among human beings, the only thing that guarantees that this project is truly open-ended, is a willingness to have our beliefs and behaviors modified by the power of conversation.”

“The core of science is not controlled experiment or mathetical modeling; it is intellectual honesty. It is time we acknowledge a basic feature of human discourse: when considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't.”

“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?”
