Not yet but bought it, as I mentioned before. I thought Buddhism without Belief was pretty strong, this book supposedly goes into historical stuff. Reading some of the many reviews on Amazon it looks bloody awesome.
So, it might be a good idea to read it before discussing it. You see, when people discuss a book or article or essay or literary work, it helps if they have a clue what they are talking about.
I've just ordered it.....but won't be commenting until I've read it. Just reading and paraphrasing the info on the jacket won't be that useful in a discussion either!
