My rating of this book is based almost entirely on its writing quality, because I still dont know what I think about its content. I strongly agreed with some sections, but strongly questioned others. That said, the ideas presented in this book are interesting and worth considering. If I needed to have an opinion about the content, I think that the book tried to do too much and, if it had expanded just one of the chapters to the entire book, would have been much more compelling.
The writing was competent, but some sections were hard to get through. In several chapters, there were simply lists of experiences that acted as evidence, but were difficult for me to get through without individual interpretation and context.
