It's easy to sell good news like this, and the authors confidently rely on classic fallacious arguments. They argue by declaration, which is what makes the books so amusing. In matter-of-fact, authoritative tones, the authors tell us how plants and human beings exchange energy - or they describe what angels look like, whether or how they're sexed, how they communicate with human beings, and how they differ from ghosts. Readers might be expected to wonder, How do they know?

I do what I do because I have a compulsion to hold forth. I don't spend a lot of time, if any, thinking about the effect my work is going to have on the world. And I have an abiding mistrust of people who think that they're going to change the world. I think that people who think that they're going to change the world are the kind of people who put bombs on airplanes.

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 might once have been called whining is now exalted as a process of asserting selfhood; self-absorption is regarded as a form of self-expression.

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.

The dissemination of pseudoscience, including such things as the fascination with near-death experiences and the growing belief by Americans -- 34 percent of them -- in reincarnation are dangerous. They help to break down the standards of reason.

I don't think of myself as having a particular role. I'm lucky enough to be able to make my living essentially by expressing my opinions. But, you know, I think the world would manage quite well if I weren't doing it.
