Not really that good.
If it is compared to Moral Landscape by Sam Harris or The Moral Arc by Michael Shermer, it is comparatively shallow and confusing.
Not fair. I know.
It is still an interesting take, a form of thought exercise to pick out where the writer has missed the mark in reality.
I have read another bad review for this book by a writer I hate, John Gray. That's why this book is given a chance to make it to the pile.
