There could be no more powerful argument against mixing religion and government than the success of independent African American churches in placing racial segregation and discrimination on a reluctant nation's social agenda. Would black churches have been able to take the lead in the struggle had they been dependent on funds doled out for 'faith-based initiatives' . . . ?

I have received many touching letters and emails from people who live in the most religious parts of the country, in places like rural Texas, saying it is so good to see someone be able to say I am an atheist without shame.

The biggest religious wars and persecutions in history occur when religions, each claiming their own absolute truths, come into conflict.

I still do find the prayers of the Kaddish quite moving, and I just substitute in my mind nature, although that's what the founders did in a lot of their documents, too. They substituted nature or providence for God. I think that's what I do in my head with Jewish God.

That so many manage to accommodate belief systems encompassing both the natural and the supernatural is a testament not to the compatibility of science and religion but to the flexibility, in both the physical and metaphysical senses, of the human brain.

For one thing, the Catholic Church in particular has this one thing - confession - in which you could go, confess to a priest and obtain absolution of your sins. And there was a routine and a ritual and I think - I think that it did help.

I don't see why any president has to talk about his belief in God.
