I have a Ph.D. in cell biology. And that's really manual labor. I mean, experimental science, you do it with your hands. So it's very different. You're out there in a lab, cleaning test tubes, and it just wasn't that fascinating.

It was a real surprise to me to come across the evidence that Christianity might once have been a danced religion. Certainly, some of the early church leaders thought this was great and spoke of what seems to have been circle dancing, perhaps around an altar.

Americans love marriage too much. We rush into mariage with abandon, expecting a micro-Utopia on earth. We pile all our needs onto it, our expectations, neuroses, and hopes. In fact, we've made marriage into the panda bear of human social institutions: we've loved it to death.

Heads of state are notoriously ill prepared for their mature careers; think of Adolf Hitler (landscape painter), Ho Chi Minh (seaman), and our own Ronald Reagan.

For a long time on Earth humans didn't worship good gods; that's a new idea. The ancient Greek gods, the Hindu gods, are fairly amoral, most of them. We get stuck when we insist that God be both good and all-powerful.

As a general rule, when something gets elevated to apple-pie status in the hierarchy of American values, you have to suspect that its actual monetary value is skidding toward zero. Take motherhood: nobody ever thought of putting it on a moral pedestal until some brash feminists pointed out, about a century ago, that the pay is lousy and the career ladder nonexistent. Same thing with work: would we be so reverent about the 'work ethic' if it wasn't for the fact that the average working stiff's hourly pay is shrinking, year by year.

People tend to judge presidents on how the economy performs, and yet we don't expect them to have the power to do much about it. Or we don't want them to exercise that power, if they were to have it.
