Enlightenment Now: The Case for Reason, Science, Humanism, and Progress is a 2018 book written by Canadian-American cognitive scientist Steven Pinker. It argues that the Enlightenment values of reason, science, and humanism have brought progress; shows our progress with data that health, prosperity, safety, peace, and happiness have tended to rise worldwide; and explains the cognitive science of why this progress should be appreciated. It is a follow-up to Pinker's 2011 book, The Better Angels of Our Nature.
