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.

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.
