I read this book most of the way through, was troubled by the author's approach but was getting some useful tid bits here and there. About page 419 in the paper back though, I ran into his explication of his causal reasoning, (a subject of study I am intimately and professionally familiar with) and it was complete jibberish, its as if a comedian were pretending to speak chinese by reciting a bunch of menu items from the corner noodle shop. Given this level lazy ignorance, I simply let the book drop, most of his previous, already less than convincing, arguments were cast in a much harsher light. This is too bad, some of the info seemed genuinely useful.
