Enlightenment Now: The Case for Reason, Science, Humanism, and Progress

The world is giving peace a chance. War between countries is obsolescent, and war within countries is absent from five-sixths of the world’s surface. The proportion of people killed annually in wars is less than a quarter of what it was in the 1980s, a seventh of what it was in the early 1970s, an eighteenth of what it was in the early 1950s, and a half a percent of what it was during World War II. Genocides, once common, have become rare. In most times and places, homicides kill far more people than wars, and homicide rates have been falling as well. Americans are half as likely to be murdered as they were two dozen years ago. In the world as a whole, people are seven-tenths as likely to be murdered as they were eighteen years ago.

Life has been getting safer in every way. Over the course of the 20th century, Americans became 96 percent less likely to be killed in a car accident, 88 percent less likely to be mowed down on the sidewalk, 99 percent less likely to die in a plane crash, 59 percent less likely to fall to their deaths, 92 percent less likely to die by fire, 90 percent less likely to drown, 92 percent less likely to be asphyxiated, and 95 percent less likely to be killed on the job.² Life in other rich countries is even safer, and life in poorer countries will get safer as they get richer.

People are getting not just healthier, richer, and safer but freer. Two centuries ago a handful of countries, embracing one percent of the world’s people, were democratic; today, two-thirds of the world’s countries, embracing two-thirds of its people, are. Not long ago half the world’s countries had laws that discriminated against racial minorities; today more countries have policies that favor their minorities than policies that discriminate against them. At the turn of the 20th century, women could vote in just one country; today they can vote in every country where men can vote save one. Laws that criminalize homosexuality continue to be stricken down, and attitudes toward minorities, women, and gay people are becoming steadily more tolerant, particularly among the young, a portent of the world’s future. Hate crimes, violence against women, and the victimization of children are all in long-term decline, as is the exploitation of children for their labor.

As people are getting healthier, richer, safer, and freer, they are also becoming more literate, knowledgeable, and smarter. Early in the 19th century, 12 percent of the world could read and write; today 83 percent can. Literacy and the education it enables will soon be universal, for girls as well as boys. The schooling, together with health and wealth, are literally making us smarter—by thirty IQ points, or two standard deviations above our ancestors.

People are putting their longer, healthier, safer, freer, richer, and wiser lives to good use. Americans work 22 fewer hours a week than they used to, have three weeks of paid vacation, lose 43 fewer hours to housework, and spend just a third of their paycheck on necessities rather than five-eighths. They are using their leisure and disposable income to travel, spend time with their children, connect with loved ones, and sample the world’s cuisine, knowledge, and culture. As a result of these gifts, people worldwide have become happier. Even Americans, who take their good fortune for granted, are “pretty happy” or happier, and the younger generations are becoming less unhappy, lonely, depressed, drug-addicted, and suicidal.

As societies have become healthier, wealthier, freer, happier, and better educated, they have set their sights on the most pressing global challenges. They have emitted fewer pollutants, cleared fewer forests, spilled less oil, set aside more preserves, extinguished fewer species, saved the ozone layer, and peaked in their consumption of oil, farmland, timber, paper, cars, coal, and perhaps even carbon. For all their differences, the world’s nations came to a historic agreement on climate change, as they did in previous years on nuclear testing, proliferation, security, and disarmament. Nuclear weapons, since the extraordinary circumstances of the closing days of World War II, have not been used in the seventy-two years they have existed. Nuclear terrorism, in defiance of forty years of expert predictions, has never happened. The world’s nuclear stockpiles have been reduced by 85 percent, with more reductions to come, and testing has ceased (except by the tiny rogue regime in Pyongyang) and proliferation has frozen. The world’s two most pressing problems, then, though not yet solved, are solvable: practicable long-term agendas have been laid out for eliminating nuclear weapons and for mitigating climate change.
