Query: Full of Errors and Misconceptions

I have read many books on the subject, and I'm not sure this author has a grasp of the concepts. It reads as though it was pasted together from magazine articles, and there is very little to tie the disparate thoughts together. The author seems confused, as there are frequent contradictions, more than once in the same chapter. If you are only going to read one book on this subject, pick one where the author has a command of the topic; this one will leave you as befuddled as the author.
