Sure, this book was a compelling read that offered us all some great amo for cocktail party conversation. But ultimately I think most of what Leavitt claims is crap.
He dodges accoutability with the disclaimer about his book NOT being a scholarly work, but then goes on to drop statistics, theories and expert opinions. These assertions laid, he doesn't provide readers with enough information to critically examine his perspectives.
Ultimately I have a problem with the unquestioned, unaccoutable role of the public intellectual. Leavitt dances around with his PhD on his sleeve, but is never subject to peer review or any sort of academic criticism. I think it's irresponsible.
