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.
