content: I have heard it argued that this book is dry and unreadable. Personally, I think that those who would call it dry mistake a lack of flowery language for clarity of voice.While it clearly has an agenda to prove, this book is very well articulated and supports most of its ideas very well with facts. Nothing is ever proven (a difficult task indeed!), but the information presented is very compelling, and, even if you are not swayed by Diamond's thesis, the wealth of interesting data presented in an interesting and understandable fashion makes it worth the read.
