I wanted this book to be more than it was, which was really a summary of epidemiological data. I found it odd how Torrey managed to virtually ignore the diathesis stress theory even when it could have shed light on multiple findings discussed in the text.I also found Torrey's relentless use of the term "schizophrenic" to be jarring. By now this book is over 30 years old, which makes a lot of the content dated and therefore it may be unfair to critique it.I'm still glad I read it given the unique scope and perspective.
