A few weeks later, I’m in a fluorescent-lit classroom in Chelsea awaiting the start of the official Mensa test. I’m sitting next to a guy who’s doing a series of elaborate neck stretches, like we’re about to engage in a vigorous rugby match. He’s neatly laid out four types of gum on his Formica desk: Juicy Fruit, Wrigley Spearmint, Big Red, and Eclipse. I hate this guy. I hope to God he’s not a genius.

It comes back to the old question: How can the Bible be so wise in some places and so barbaric in others? And why should we put any faith in a book that includes such brutality?

I tried the paleo diet, which is the caveman diet - lots of meat. I tried the raw food vegan diet. And I tried the calorie restriction diet, which is the idea is that if you eat very, very little - if you're on the verge of starvation, you will live a very long time. Whether or not you want to, of course, is the idea.

I'm all for cafeteria religion. I think there's nothing wrong with cafeterias - I've had some great meals at cafeterias. I've also had some horrible meals, so it's important to pick the right things. Take a heaping helping of compassion and mercy, and leave the intolerance on the table.

Giulia Melucci has written a wonderfully funny and moving book. It's like Eat, Pray, Love, with recipes.

The Bible improved my ethical IQ. I started to act like a good person. I tried not to gossip, and lie, and covet, and just by pretending I was a good person, I think I actually became a little bit better of a person. I'm not Gandhi or Angelina Jolie, but it was a baby step.
