I've just re-read Better Angels and it's terrific.  Pinker shines a beam of analysis through the dark media images of "breaking news exclusives" and instant access to every hell-in-a-hand-basket story in every corner of the globe.  In doing so he reveals that violence world-wide is on the decline.  Contrary to media stories, things are getting better, not worse! 

Pinker is no slouch waxing eloquent.  He is an award-winning, Harvard based, Canadian-born experimental and cognitive psychologist.  Twice nominated for the Pulitzer Prize, Time Magazine named him one of the world's 100 most influential scientists. 

"The central thesis of “Better Angels” is that our era is less violent, less cruel and more peaceful than any previous period of human existence.  The decline in violence holds for violence in the family, in neighborhoods, between tribes and between states. " 

Pinker's book Better Angels of Our Nature reexamines the history of violence

First they say Pinker ventures too far outside his field of expertise.  Now there's an irony-drenched slam (Herman is a professor of finance and Peterson a journalist).​Then they claim Pinker "completely ignores the kind of violence that is built into the structure of social relations and shows up…as unequal life chances…such as the savage global class war of the 1 percent against the other 99”. 

Wandering so blithely onto the thin ice of political polemics, I wonder how long it would take their "savage global class war" to crash through the frozen pond of cultural relativism upon witnessing the bloody genocidal slaughter of the Mongol invasions or a half million murdered during the Christian Inquisitions? 

Perhaps the long-term decline of violence will not persist.  Perhaps war will break out over environmental collapse or an empty island in the East China Sea.  There are plenty of problems to fix, especially the environment!  And crime still persists.
