This books isn't prose. The subtitle for the book claims that there are essays in there - there aren't. It looks like it might be the rough notes for a presentation. Maybe if you already know what he's talking about there are some interesting things being said. There's no structured argument, no narrative. Feels like marking an undergraduate essay. Student is possibly clever, possibly has something to say but appears unaware that there is any craft or application required to communicate in writing.
Ugh! Publish on demand in the worst form I've seen.
