Was he attempting to be insightful? There wasn't a single insight in that book.
Yes, any one who has read reasonable portions of the Bible know that it was written in and for a time that has long long lapsed. Many of the bidden rules cannot be taken literally - so was there a hidden message in there? AJ doesn't know. In showing the world that you cant take the Bible literally, did he unearth a morale cleansing of the spirit by showing that even these inapplicable rules have character? AJ doesn't do that either. So then he was trying to make light of it, perhaps? No, the book spends a lot of time analyzing laws of the Bible literally without context, discussing his beard, the clothes he is supposed to wear, the food he eats, his fear of germs, his journeys and interviews with leaders of religion and his wife's cycles. Then it ends there.
Anyways, I find AJ Jacobs a very boring author. I have seen great reviews of the book but I just don't get it. Maybe I should try this book years from now when I have mellowed as much as AJ has.
