What it argues
The Better Angels of Our Nature is Steven Pinker's argument, supported by extensive historical and statistical data, that human violence has declined dramatically over long time periods and that this decline is real, not an artifact of reporting or perception. The thesis is counterintuitive: most people believe the twentieth century was the most violent in history, and most people believe the world is getting more violent. Pinker argues both beliefs are wrong.
The case is built in layers. Prehistoric and early historical societies were substantially more violent than modern ones: archaeological evidence of interpersonal violence, combined with ethnographic data from hunter-gatherer and tribal societies, suggests that several percent of all deaths in pre-state societies were caused by other people. State formation reduced that rate dramatically by creating monopolies on force and systems of deterrence. Medieval European homicide rates were ten to fifty times higher than modern ones. Judicial torture was routine; public execution was entertainment. The decline of these practices was real and measurable.
What it gets right
- 1.
Violence per capita has declined over long historical timescales, from prehistoric hunter-gatherer societies through the present. This decline is real and measurable, even if the twentieth century appears violent in absolute terms.
- 2.
State formation dramatically reduced interpersonal violence by creating monopolies on force and predictable systems of deterrence and punishment.
- 3.
The decline of state torture, public execution, and gladiatorial entertainment reflects a genuine expansion of the moral circle — the set of beings whose suffering is considered to matter.
