Paine, the man who coined the words "United States of America" and another of the USA's non-Christian founding fathers, has written what is easily the best book about deism, period. I personally do not accept the arguments from either design or the anthropic principle, so I am not a deist (luckily, you won't find nasty words like "anthropic" in this book, just some outdated English).
But what this book does for biblical criticism is wonderful. Paine burns the "Good News" to ashes with his wit and brilliant prose. This book, although it would clearly violate the separation of church and state to have it read in schools, should nevertheless be read by young people (I read it when I was 18) who are interested in religion. Paine honestly looks at the bible, and finds it (correctly) to be a pack of lies.
I won't quote from the book, but I can say that what you read in it will never be used by the religious right when they spout their drivel about our's being a Christian nation.
We are lucky to have had an American as bold as Thomas Paine to write the truth about religion, I only wish there were people like that today.
