Our belief is not a belief. Our principles are not faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake... We are not immune to the lure of wonder and mystery and awe: we have music and art and literature, and find that the serious ethical dilemmas are better handled by Shakespeare and Tolstoy and Schiller and Dostoyevsky and George Elliot than in the mythical morality tales of the holy books. Literature, not scripture, sustains the mind and – since there is no other metaphor – also the soul. We do not believe in heaven or hell, yet no statistic will ever find that without these blandishments and threats we commit more crimes of greed or violence than the faithful. (In fact, if a proper statistical inquiry could ever be made, I am sure the evidence would be the other way.)... We are reconciled to living only once, except through our children, for whom we are perfectly happy to notice that we must make way, and room. We speculate that it is at least possible that, once people accepted the fact of their short struggling lives, they might behave better toward each other and not worse. We believe with certainty that an ethical life can be lived without religion. And we know for a fact the corollary holds true—that religion has caused innumerable people to not just to conduct themselves no better than others, but to award themselves permission to behave in ways that would make a brothel-keeper or an ethnic cleanser raise an eyebrow... There is no need for us to gather every day, or every seven days, or on any high and auspicious day, to proclaim our rectitude or to grovel and wallow in our unworthiness. We atheists do no require any priests, or any hierarchy above them, to police our doctrine. Sacrifices and ceremonies are abhorrent to us, as are relics and the worship of any images or objects. To us no spot on earth is or could be “holier” than another: to the ostentatious absurdity of the pilgrimage, or the plain horror of killing civilians in the name of some sacred wall or cave or shrine or rock, we can counterpose a leisurely or urgent walk from one side of the library or the gallery to another, or to lunch with an agreeable friend, in pursuit of truth or beauty.
