Query: Interesting topic, but tedious treatment

I agree with the author's general conclusion (religion does more harm than good, and we should discard it) but I can't recommend this book. The author drones on and on about the philosophical aspects of morality and ethics. Ugh. Some people may enjoy reading that sort of stuff (for page after endless page), but I'd rather have a root canal.
