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

Steven Pinker uses data to argue that the human condition is improving despite widespread cultural pessimism. He builds his case on four pillars: reason, science, humanism, and progress. Through seventy-five charts and graphs, Pinker documents global trends in life expectancy, literacy, safety, and wealth. He explains that Enlightenment values have systematically reduced poverty and violence while increasing leisure time and democratic representation. The text attributes these gains to the application of scientific knowledge and secular ethics rather than religious dogma or romantic nationalism.
