I heard this interview on NPR yesterday and thought it was interesting food for thought. The author of the book they interview picks up on one of the threads in Tapestry's approach to the early books of the Bible (the shepherd theme and its difference from Egypt).

I don't agree with everything this gentleman said, but it was interesting.
