We are living in the most moral period of our species’ history. Ever since the Enlightenment, thinkers have consciously applied the methods of science to solve social and moral problems, and in the process created the modern world of liberal democracies, civil rights, equal justice, open political and economic borders, and prosperity the likes of which no human society in history has ever enjoyed. More people in more places have greater rights, freedoms, liberties, literacy, education, and prosperity—the likes of which no human society in history has ever enjoyed.
