Title: A well written treatise on the subject.
Review: This small book is much more than it at first appears. It is a scholarly work exploring the history and meaning of the subject. It talks about what it is, and what it is not, and the shades of gray between Humbug and pure bulls***. It is not an easy read, but it is worth the effort. There is so much Bulls*** in the world it is a good thing to understand and maybe even appreciate it.
