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.

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.

Interactivity has the virtue of democracy, conferring upon everyone with access to a computer the right and opportunity to be heard, but it's also saddled with democracy's vice - a tendency to assume that everyone who has a right to be heard has something to say that's worth hearing.

The phenomenal success of the recovery movement reflects two simple truths that emerge in adolescence: all people love to talk about themselves, and most people are mad at their parents. You don't have to be in denial to doubt that truths like these will set us free.

The magical thinking encouraged by any belief in the supernatural, combined with the vilification of rationality and skepticism, is more conducive to conspiracy theories than it is to productive political debate.

Jerry Falwell knows who caused the terrorist attack on America: the ACLU. "The ACLU's got to take a lot of blame for this," he declared on the 700 Club, because, he explained, the ACLU, abetted by the federal courts is responsible for "throwing God out of the public square (and) the public schools." This is a familiar charge and a false one. God is still present in the public schools, where students are free to pray, alone or in groups, so long as their prayers aren't officially sponsored and don't infringe on anyone's freedom not to pray.
