The Roots of Progress

The Better Angels of Our Nature

Why Violence Has Declined

The story of how and why the world has gotten safer and more peaceful, from tribal societies to today, thanks to the forces of government, commerce, and reason. See my summary.

I wholeheartedly recommend this book; it was my favorite of the ones I read in 2017.
