Having listened to "The Better Angels of Our Nature" with great pleasure, I was perhaps primed to expect too much from this earlier and equally lengthy audiobook. But where as the aforementioned kept my interest throughout, there are some parts of this book that are deeply, deeply dull to anyone but the specialist.
The second six-hour block of the book is given over entirely to optics and perception, a subject difficult enough to grasp in written words, let alone being read out aloud. - As this section drags on it becomes more and more of chore to listen to, which is a shame because there is so much in this book worth listening to on both sides of that abyss.
An editor with a bit more nerve might have insisted that Pinker truncate that section of the book which was clearly the author's person hobby horse, alas listeners will have to suffer for the sake of it.
An excellent book, very listenable, packed with the kinds of scientific details and statistical observations that make Harris so popular. I'm not (as yet) sure whether I agree with Harris' central thesis, there's some complex ideas in the book that request and require some detailed, analytical thinking that are not always the priority of a first hearing, but - gladly - it's short enough to allow for multiple readings without any major innconveniance.
A lucid exposition of the ideas facing physicists and theorists of today, Michio Kaku's exposition is sublime, something you can listen to over and over again.
