Haidt and Lukianoff in The New York Times:
Before he died, Senator John McCain wrote a loving farewell statement to his fellow citizens of “the world’s greatest republic, a nation of ideals, not blood and soil.” Senator McCain also described our democracy as “325 million opinionated, vociferous individuals.” How can that many individuals bind themselves together to create a great nation? What special skills do we need to develop to compensate for our lack of shared ancestry? When Alexis de Tocqueville toured America in 1831, he concluded that one secret of our success was our ability to solve problems collectively and cooperatively. He praised our mastery of the “art of association,” which was crucial, he believed, for a self-governing people.
In recent years, however, we have become less artful, particularly about crossing party lines. It’s not just Congress that has lost the ability to cooperate. As partisan hostility has increased, Americans report feeling fear and loathing toward people on the other side and have become increasingly less willing to date or marry someone of a different party. Some restaurants won’t serve customers who work for — or even just support — the other team or its policies. Support for democracy itself is in decline. What can we do to reverse these trends? Is there some way to teach today’s children the art of association, even when today’s adults are poor models? There is. It’s free, it’s fun and it confers so many benefits that theAmerican Academy of Pediatrics recently urged Americans to give far more of it to their children. It’s called play — and it matters not only for the health of our children but also for the health of our democracy.
