The beginning is very interesting. He starts explaining epistemology, and the scientific method. He also talks about some interesting cases. Towards the middle/end, he starts talking about astrology, making some points about paradigm shifts, but then continues with astrology till the end... I had the feeling we were kind of living the reason why a person would by the book in the first place. Buying for how a belief is put into place then destroyed, to long history of astrology. However; he explains it very well, and has made me more curious about the universe!
