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.

As Camille Paglia's success has demonstrated, what is most marketable is absolutism and attitude undiluted by thought.

In this climate - with belief in guardian angels and creationism becoming commonplace - making fun of religion is as risky as burning a flag in an American Legion hall.

There is this fashionable progressive notion that everything is so completely political that the idea we could have some sort of neutral legal process is practically utopian - because we all know that the more money you have, the more rights you can exercise in this society. But I don't think that you deal with income inequality by limiting the First Amendment rights of affluent people. I'd rather see people screw around with the tax code to redistribute wealth a little bit than screw around with the First Amendment.

One of the reasons I'm drawn to civil libertarianism as opposed to communitarianism is that I don't worry so much about the rights of the majority; a majority is quite capable of enforcing and protecting its own rights.

I don't spend much time thinking about whether God exists. I don't consider that a relevant question. It's unanswerable and irrelevant to my life, so I put it in the category of things I can't worry about.

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?
