Query: Most thought provoking book I've read in 10 years!!!

I heard Dr. Shlain on KPFA radio, and was so inspired I bought the book. The next 3 weeks of my life were lost in deep concentration as he traced the history of culture and religion. I was required to remember all the history I learned as a youth, and with that and an open mind, I viewed history with a new reference. I now understand why Waldorf teaches art before reading. The book is extremely thought provoking and I highly recommend it to everyone.
