The most transformative experiences people have - bliss, devotion, self transcendence - are currently anchored to the worst parts of culture and to ways of thinking that merely amplify superstition, self-deception, and conflict.

How can we encourage other human beings to extend their moral sympathies beyond a narrow locus? How can we learn to become mere human beings, shorn of any more compelling national, ethnic, or religious identity? We can be reasonable. It is in the very nature of reason to fuse cognitive and moral horizons. Reason is nothing less than the guardian of love.

The core of science is not a mathematical modeling--it is intellectual honesty. It is a willingness to have our certainties about the world constrained by good evidence and good argument.

We are now in the 21st century: all books, including the Koran, should be fair game for flushing down the toilet without fear of violent reprisal.

The problem is that religion tends to give people bad reasons to be good.

About 120 million of us place the big bang 2,500 years after the Babylonians and Sumerians learned to brew beer. If our polls are to be trusted, nearly 230 million Americans believe that a book showing neither unity of style nor internal consistency was authored by an omniscient, omnipotent and omnipresent deity.

To speak plainly and truthfully about the state of our world - to say, for instance, that the Bible and the Koran both contain mountains of life-destroying gibberish - is antithetical to tolerance as moderates currently conceive it. But we can no longer afford the luxury of such political correctness. We must finally recognize the price we are paying to maintain the iconography of our ignorance.
