Steven Pinker writes about the massive decline of violence:
Whatever its causes, the implications of the historical decline of violence are profound. So much depends on whether we see our era as a nightmare of crime, terrorism, genocide and war or as a period that, in the light of the historical and statistical facts, is blessed by unprecedented levels of peaceful coexistence.Also check out the video for his awesome hairdo:
Bearers of good news are often advised to keep their mouths shut, lest they lull people into complacency. But this prescription may be backward. The discovery that fewer people are victims of violence can thwart cynicism among compassion-fatigued news readers who might otherwise think that the dangerous parts of the world are irredeemable hell holes. And a better understanding of what drove the numbers down can steer us toward doing things that make people better off rather than congratulating ourselves on how moral we are.
