What makes fantastic declarations believable is, in part, the vehemence with which they're proffered. Again, in the world of spirituality as well as of pop psychology, intensity of personal belief is evidence of truth. It is considered very bad form - even abuse - to challenge the veracity of any personal testimony that might be offered in a twelve-step group or on a talk show, unless the testimony itself is equivocal... Whatever sells, whatever many people believe strongly, must be true.

There's a way in which all of these grazers at the spirituality buffet are performing a service, because you could argue that grazing leads to a kind of tolerance. People who incorporate teachings from a lot of different traditions into their own belief systems are going to be more tolerant than people who confine themselves within the strict boundaries of one particular religion. Does it contribute to our confusion? I don't know if it contributes to confusion so much as it is evidence of a certain kind of silliness and shallowness.

Whatever lessons we take from this dreadful attack (on the World Trade Center and Pentagon), we should never forget that it was, after all, a faith based initiative.

I don't care if religious people consider me amoral because I lack their beliefs in God. I do however care deeply about efforts to turn religious beliefs into law and those efforts benefit greatly from the conviction that individually and collectively we cannot be good without God.

We don't cut off the hands of thieves or castrate rapists. Why must we murder murderers?

The press and the public like certainty and affirmation of popular biases. But real science thrives on the capacity for doubt.

The scarcest resource these days is reason. What's certainly striking about American culture today is the great hostility toward science and the decline of respect for rational scientific thinking. People seem to think that we are ruled by the scientific method and that we overvalue reason. If there was ever a period when we overvalued reason, I think that it was probably extremely brief. What I see now is a great deal of superstition, as much superstition as there has ever been. There are probably more people who believe in guardian angels than who understand the law of gravity.
