A kernel of truth lurks at the heart of religion, because spiritual experience, ethical behavior, and strong communities are essential for human happiness. And yet our religious traditions are intellectually defunct and politically ruinous. While spiritual experience is clearly a natural propensity of the human mind, we need not believe anything on insufficient evidence to actualize it.

The science of morality is about maximizing psychological and social health. It's really no more inflammatory than that.

Liberals tend to understand that a person can be lucky or unlucky in all matters relevant to his success. Conservatives, however, often make a religious fetish of individualism. Many seem to have absolutely no awareness of how fortunate one must be to succeed at anything in life, no matter how hard one works. One must be lucky to be able to work. One must be lucky to be intelligent, physically healthy, and not bankrupted in middle age by the illness of a spouse.

And while Protestant reformers broke with Rome on a variety of counts, their treatment of their fellow human beings was no less disgraceful. Public executions were more popular than ever: heretics were still reduced to ash, scholars were tortured and killed for impertinent displays of reason, and fornicators were murdered without a qualm.

People who harbor strong convictions without evidence belong at the margins of our societies, not in our halls of power.

Despite a full century of scientific insights attesting to the antiquity of the earth, more than half of our neighbors believe that the entire cosmos was created six thousand years ago. This is, incidentally, about a thousand years after the Sumerians invented glue.

What we do in every other area of our lives (other than religion), is, rather than respect somebody's beliefs, we evaluate their reasons.
