When Bill Gates was finished with this book, he considered it to be an all time favourite. After reading it myself, I find it easy to see why.
Violence has declined considerably. This much is a fact. In this book, Pinker goes over reasons why he believes this has happened.
In Better Angels Pinker takes us on a journey through time, telling the story of a species that slowly came to learn a valuable lesson - that we shouldn't kill one another.
A truly uplifting read.
