A lot of people are selling Enlightenment these days. After the Brexit vote and the election of President Trump, David Brooks published a paean to the “Enlightenment project,” declaring it under attack and calling on readers to “rise up” and save it. Commentary magazine sent me a letter asking for a donation to provide readers “with the enlightenment we all so desperately crave.” And now there’s Steven Pinker’s impressive new book, “Enlightenment Now,” which may be the definitive statement of the neo-Enlightenment movement that is fighting the tide of nationalist thinking in America, Britain and beyond.
Do we all crave enlightenment? I don’t. I like and respect Mr. Pinker, Mr. Brooks and others in their camp. But Enlightenment philosophy didn’t achieve a fraction of the good they claim, and it has done much harm.
Boosters of the Enlightenment make an attractive case. Science, medicine, free political institutions, the market economy—these things have dramatically improved our lives. They are all, Mr. Pinker writes, the result of “a process set in motion by the Enlightenment in the late 18th century,” when philosophers “replaced dogma, tradition and authority with reason, debate and institutions of truth-seeking.” Mr. Brooks concurs, assuring his readers that “the Enlightenment project gave us the modern world.” So give thanks for “thinkers like John Locke and Immanuel Kant who argued that people should stop deferring blindly to authority” and instead “think things through from the ground up.”
