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… - Sam Harris

And then came the insight that irrevocably transformed my sense of how good human life could be. I was feeling boundless love for one of my best friends, and I suddenly realized that if a stranger had walked through the door at that moment, he or she would have been fully included in this love. Love was at bottom impersonal — and deeper than any personal history could justify. Indeed, a transactional form of love — I love you because. . . — now made no sense at all.

This is not (as you have charged) to paint religion with a broad brush. I am very quick to distinguish gradations of bad ideas; some clearly have no consequences at all (or at least not yet); some put civilization itself in peril. The problem with dogmatism, however, is that one can never quite predict how terrible its costs will be. To use one of my favorite examples, consider the Christian dogma that human life begins at the moment of conception: On its face, this belief seems likely to only improve our world. After all, it is the very quintessence of a life-affirming doctrine.

Enter embryonic stem-cell research. Suddenly, this “life begins at the moment of conception” business becomes the chief impediment to medical progress. Who would have thought that such an innocuous idea could unnecessarily prolong the agony of tens of millions of people? This is the problem with dogmatism, no matter how seemingly benign: it is unresponsive to reality. Dogmatism is a failure of cognition (as well as a commitment to such failure); it is the state of being closed to new evidence and new arguments. And this frame of mind is rightly despised in every area of culture, on every subject, except where it goes by the name of “religious faith.” In this guise, parading its most grotesque faults as virtues, it is granted a special dispensation, even in the pages of Nature.

This universe is shot through with mystery. The very fact of its being, and of our own, is a mystery absolute, and the only miracle worthy of the name. The consciousness that animates us is itself central to this mystery and the ground for any experience we might wish to call 'spiritual.' No myths need be embraced for us to commune with the profundity of our circumstance. No personal God need be worshiped for us to live in awe at the beauty and immensity of creation. No tribal fictions need be rehearsed for us to realize, one fine day, that we do, in fact, love our neighbors, that our happiness is inextricable from their own, and that our interdependence demands that people everywhere be given the opportunity to flourish.
