I wanted to love this book and it made several great points that should not be downplayed (Bayes Theorem, etc), but Pinker decides to use politics and the last few years to justify the theories and discussion rather than statistical data. In doing so, Pinker reverts to the arguments his book his trying to dissuade. The last chapter focuses on the future and again heavily involves more politics without actual data to back up. While this book is timely in current years, I'm curious if it stands the test of time. Foundational argument is there, but it fails to deliver its key points without pushing forth a narrative and political agenda.
