I warn my students. At the start of every semester, on the first day of every course, I confess to certain passions and quirks and tell them to be ready: I’m a stickler for correct grammar, spelling and the like, so if they don’t have it in them to care about and patrol for such errors, they probably won’t end up with the grade they’re after. I want to hear everyone’s voice — I tell them that, too — but I don’t want to hear anybody’s voice so often and so loudly that the other voices don’t have a chance.

And I’m going to repeat one phrase more often than any other: “It’s complicated.” They’ll become familiar with that. They may even become bored with it. I’ll sometimes say it when we’re discussing the roots and branches of a social ill, the motivations of public (and private) actors and a whole lot else, and that’s because I’m standing before them not as an ambassador of certainty or a font of unassailable verities but as an emissary of doubt. I want to give them intelligent questions, not final answers. I want to teach them how much they have to learn — and how much they will always have to learn.

I’d been on the faculty of Duke University and delivering that spiel for more than two years before I realized that each component of it was about the same quality: humility. The grammar-and-spelling bit was about surrendering to an established and easily understood way of doing things that eschewed wild individualism in favor of a common mode of communication. It showed respect for tradition, which is a force that binds us, a folding of the self into a greater whole. The voices bit — well, that’s obvious. It’s a reminder that we share the stages of our communities, our countries, our worlds, with many other actors and should conduct ourselves in a manner that recognizes this fact. And “it’s complicated” is a bulwark against arrogance, absolutism, purity, zeal.

I’d also been delivering that spiel for more than two years before I realized that humility is the antidote to grievance.

We live in an era defined and overwhelmed by grievance — by too many Americans’ obsession with how they’ve been wronged and their insistence on wallowing in ire. This anger reflects a pessimism that previous generations didn’t feel. The ascent of identity politics and the influence of social media, it turned out, were better at inflaming us than uniting us. They promote a self-obsession at odds with community, civility, comity and compromise. It’s a problem of humility.

The Jan. 6 insurrectionists were delusional, frenzied, savage. But above all, they were unhumble. They decided that they held the truth, no matter all the evidence to the contrary. They couldn’t accept that their preference for one presidential candidate over another could possibly put them in the minority — or perhaps a few of them just reasoned that if it did, then everybody else was too misguided to matter. They elevated how they viewed the world and what they wanted over tradition, institutional stability, law, order.
