"A Thorough Study and an Enjoyable Listen"
Arthur Morey does an excellent job with the narration. I found his voice engaging during the entirety of the almost 37 hours of this audiobook.
As one would hope for a book this lengthy, Steven Pinker doesn't waste your time. After a brief introduction, the book takes off into a systematic and thoroughgoing analysis of just about all the data one could ask for on this topic. He gives the numbers, the studies, etc. and explains them at every step of the way. He goes into quite a bit of history, biology, neuroscience, politics, law, and several other subjects relevant to the topic which were a pleasure to learn about for their own sake. I found that Pinker even anticipated nearly every question I had, usually only a few sentences after it popped into my mind. I don't think one could ask for a better book the subject.
Steven Pinker writes near the end of the book, "...and I hope that the numbers I have marshaled have lifted your assessment of the state of the world from the lugubrious conventional wisdom." I can say that this has been the effect on me.
