This book is a very unusual mix of literary & philosophical references & more practical facts, making it a fascinating read. My only real complaint was the occasional sleazy reference - the crude description of oral sex on p.207 being one of them. I am not a prude but the crude language used here & in a couple of other spots jarred with the intelligence evident in the rest of the book.
I also felt uncomfortable with Tallis' description of 'worked-up parents' in the Alder Hey affair. Whatever his personal view on the situation, his cryptic criticisms of the parents' objections made me feel uncomfortable.
Other than that, a very good read - but one which raises many questions beyond the scope of this book.
