Our seemingly troubled times are routinely contrasted with idyllic images of hunter-gatherer societies, which allegedly lived in a state of harmony with nature and each other. The doctrine of the noble savage—the idea that humans are peaceable by nature and corrupted by modern institutions—pops up frequently in the writing of public intellectuals like, for example, Spanish philosopher José Ortega y Gasset, who argued that "war is not an instinct but an invention."
But now that social scientists have started to count bodies in different historical periods, they have discovered that the romantic theory gets it backward: Far from causing us to become more violent, something in modernity and its cultural institutions has made us nobler. In fact, our ancestors were far more violent than we are today. Indeed, violence has been in decline over long stretches of history, and today we are probably living in the most peaceful moment of our species' time on earth.
A history of violence
In the decade of Darfur and Iraq, that statement might seem hallucinatory or even obscene. But if we consider the evidence, we find that the decline of violence is a fractal phenomenon: We can see the decline over millennia, centuries, decades, and years.
