Faith does not offer a strong link between our beliefs and actual states of the world.

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.

It is time we realize that belief is not a private matter. As a man believes, so he will act. Believe that you are a member of a chosen people, awash in the salacious exports of an evil culture that is turning your children away from God, believe that you will be rewarded with an eternity of unimaginable delights by dealing death to these infidels—and flying a plane into a building is only a matter of being asked to do it.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality.

It is rather more noble to help people purely out of concern for their suffering than it is to help them because you think the Creator of the Universe wants you to do it, or will reward you for doing it, or will punish you for not doing it. The problem with this linkage between religion and morality is that it gives people bad reasons to help other human beings when good reasons are available.

This is how you play tennis without the net

We have Christians against Muslims against Jews. They're making incompatible claims on real estate in the Middle East as though God were some kind of omniscient real estate broker parsing out parcels of land to his chosen flock. People are literally dying over ancient literature.
