The Better Angels of Our Nature: Why Violence Has Declined

Steven Pinker’s "The Better Angels of Our Nature" is that rare nonfiction book that dares to say something surprisingly optimistic: violence has been declining for centuries, maybe even millennia. And no, this isn’t some naive Pollyanna cheerleading. Pinker, a cognitive scientist, backs this claim with a cocktail of historical data, psychology, and sociology that’s as thorough as it is eye-opening.

At first glance, it sounds almost absurd. War, terrorism, crime—aren’t these all proof that humanity’s scratching and clawing at each other like angry cats? Pinker acknowledges this frustration but flips the script by zooming out. When you look at the big picture, the long arc of human history, the bloodshed of ancient times dwarfs what we see today. He points out that prehistoric hunter-gatherers were way more violent, with homicide rates many times higher than modern societies. Our ancestors’ daily lives were a brutal survival slog.

One of the big reasons for this decline, Pinker argues, is what he calls the "pacification process." When humans settled down from nomadic lifestyles into agricultural communities, they started forming larger social groups. This shift made random, chaotic violence less practical and less common. You can’t just pick fights willy-nilly when your neighbors are also your food suppliers and potential allies.

Then came the "civilizing process," where centralized governments and legal systems began to monopolize violence. Instead of personal revenge or clan feuds, people increasingly relied on institutions to settle disputes. This didn’t magically end violence, but it funneled it into more controlled, less frequent forms.

Pinker also highlights the "humanitarian revolution," a wave of moral progress that saw the abolition of slavery, the end of judicial torture, and growing respect for human rights. These weren’t just feel-good moments but real shifts in how societies valued human life and dignity.

The 20th century’s "long peace" and the post-Cold War "new peace" represent periods where wars between major powers and civil conflicts dropped dramatically. Despite the headlines, the number of deaths from wars has decreased when adjusted for population size.

Psychologically, Pinker doesn’t ignore the darker side of human nature. He identifies five "inner demons"—practical violence, dominance, revenge, sadism, and ideology—that drive aggression. But here’s the twist: humans also have "better angels" like empathy, self-control, moral sense, and reason. Our history is a tug-of-war between these forces, and Pinker’s thesis is that the better angels are winning, slowly but steadily.

The book’s strength lies in its massive, interdisciplinary approach. Pinker pulls from archaeology, history, psychology, and statistics to paint a broad, data-backed picture. It’s a serious antidote to the constant barrage of doom and gloom in media and popular culture.

That said, the book isn’t without its blind spots. Some critics argue Pinker glosses over ongoing violence hotspots and the persistence of systemic issues like structural racism or economic inequality that fuel conflict. Others question whether the data can really prove causality or just correlation. Are states and laws truly the cause of peace, or just one piece of a messier puzzle?

Still, "The Better Angels of Our Nature" is a refreshing, if occasionally optimistic, look at human progress. It challenges our biases toward negativity and invites readers to consider that the story of humanity might be one of gradual improvement rather than inevitable decline. It’s a conversation starter for anyone curious about where we’ve come from and where we might be headed.
