Fascinating book, pretty heavy emotionally so be prepared to read it, because basically it says that we are even more *!@#-up than we know, and it's time to make some fundamental changes.
He assigns much of the blame to Western civilization, and if you doubt it, he provides some compelling evidence.
One criticism I might make is that I wonder if environmental toxins play more of a role in emotional stress and disease, it would have been nice if the author addressed that topic. Whether you agree or not, very interesting to read and well-explained.
