Is the world really falling apart? Is the ideal of progress obsolete? Cognitive scientist Steven Pinker urges us to step back from the gory headlines and prophecies of doom, which play to our psychological biases. Instead, follow the data. In seventy-five graphs, Pinker shows that life, health, prosperity, safety, peace, knowledge, and happiness are on the rise, not just in the West, but worldwide. This progress is not the result of some cosmic force. It is a gift of the Enlightenment: the conviction that reason and science can enhance human flourishing. Far from being a naïve hope, the Enlightenment, we now know, has worked. But more than ever, it needs a vigorous defense. The Enlightenment project swims against currents of human nature -- tribalism, authoritarianism, demonization, magical thinking -- which demagogues are all too willing to exploit. Many commentators, committed to political, religious, or romantic ideologies, fight a rearguard action against it. The result is a corrosive fatalism and a willingness to wreck the precious institutions of liberal democracy and global cooperation. Pinker makes the case for reason, science, and humanism: the ideals we need to confront our problems and continue our progress.

From the Publisher: A cultural history of the last forty years, The Age of American Unreason focuses on the convergence of social forces-usually treated as separate entities-that has created a perfect storm of anti-rationalism. These include the upsurge of religious fundamentalism, with more political power today than ever before; the failure of public education to create an informed citizenry; and the triumph of video over print culture. Sparing neither the right nor the left, Jacoby asserts that Americans today have embraced a universe of "junk thought" that makes almost no effort to separate fact from opinion
