Query: Shorter's opinion on the history of psychiatry

I really enjoyed the part of this book on the history of psychiatry. Unfortunately only about 60% of the book is on this topic and the rest consists of Shorter's unbalanced opinions. As a Psychiartic Registrar/resident slightly more simpathetic to the Biological approach, even I found this book extremely biased. Shorter's concrete style of reasoning makes him far more suitable to write a book on the history of surgery. The finer nuances and richness of the field of psychiatry is clearly outside his grasp.
