We're living in primate heaven. We're warm, dry, we're not hungry, we don't have fleas and ticks and infections. So why are we so miserable?

For one thing, before the 20th century, there were plenty of genocides. We tend to forget about them, partly because they weren't as well documented and partly because, until recently, people didn't care. We used euphemisms like 'sackings' and 'sieges' instead of calling them 'genocides.'

When it comes to explaining human thought and behavior, the possibility that heredity plays any role at all still has the power to shock. To acknowledge human nature, many think, is to endorse racism, sexism, war, greed, genocide, nihilism, reactionary politics, and neglect of children and the disadvantaged. Any claim that the mind has an innate organization strikes people not as a hypothesis that might be incorrect but as a thought it is immoral to think.

A...reason we are so-so scientists is that our brains were shaped for fitness, not for truth. Sometimes truth is adaptive, but sometimes it is not.

Of course, genes can't pull the levers of our behavior directly. But they affect the wiring and workings of the brain, and the brain is the seat of our drives, temperaments and patterns of thought.

Modern biblical scholars have established that the bible is a wiki. It was compiled over half a millennium from writers with different styles, dialects, character names, and conceptions of God and was subjected to haphazard editing that left it with many contradictions, duplications and non-sequiturs.

Why is it surprising that scientists might have long hair and wear cowboy boots? In fields like neuroscience, where the events you are recording are so minute, I suspect scientists cultivate a boring, reliable image. A scientist with a reputation for flamboyance might be suspect.
