Re: "most important book"
Those morals and value judgements existed long, long before.
The idea that the world was total chaos before a highly edited compilation of short stories came out is a bit silly.
To be fair, Folio did not say that moral values were non-existent before the Bible, just that the Bible codified them and heavily influenced what we have today. Which is indisputably true, as any law student will tell us.
