The Long Peace
“Nothing can be more gentle than man in his primitive state,” declared Rousseau in the 18th century. A century earlier, Thomas Hobbes wrote, “In the state of nature the life of man is solitary, poor, nasty, brutish, and short.” The evidence shows that Rousseau was wrong and Hobbes was right, said Pinker. Forensic archaeology (“CSI Paleolithic”) reveals that 15 percent of prehistoric skeletons show signs of violent trauma. Ethnographic vital statistics of surviving non-state societies and pockets of anarchy show, on average, 524 war deaths per 100,000 people per year.
Germany in the 20th century, wracked by two world wars, had 144 war deaths per 100,000 per year. Russia had 135. Japan had 27. The US in the 20th century had 5.7. In this 21st century the whole world has a war death rate of 0.3 per 100,000 people per year. In primitive societies 15 percent of people died violently; now 0.03 percent do. Violence is 1/500th of what it used to be.
The change came by stages, each with a different dynamic. Pinker identified: 1) The Pacification Process brought about by the rise and expansion of states, which monopolized violence to keep their citizens from killing each other. 2) The Humanizing Process. States consolidated, enforcing “the king’s justice.” With improving infrastructure, commerce grew, and the zero-sum game of plunder was replaced by the positive-sum game of trade. 3) The Humanitarian Revolution. Following ideas of The Enlightenment, the expansion of literacy, and growing cosmopolitanism, reason guided people to reject slavery, reduce capital crimes toward zero, and challenge superstitious demonizing of witches, Jews, etc. Voltaire wrote: “Those who can make you believe absurdities can make you commit atrocities.”
