People who traffic in symbolic manipulation—and that’s most of us, these digital days—are typically inclined to overrate the importance of symbolic manipulation. It’s always tempting to think that to exercise control over symbols—like the Confederate battle flag, which, for the record, I have long despised—is to strike a blow for justice. Again, social media play a key role here: Jerry Gaus once wrote an article “On the Difficult Virtue of Minding One’s Own Business”, but given the hyperpublic character of the web services most of us rely on, and the difficulty of getting any of them to reliably provide intimacy gradients, everyone’s business now seems to be everyone else’s business. In such a environment, ABP—Always Be Policing—is the watchword. Survey and critique others, lest you make yourself subject to surveillance and critique. And use the proper Hashtags of Solidarity, or you might end up like that guy who was the first to stop applauding Stalin’s speech.

Minding your own business, on this commonly-held account of things, is a vice, not a virtue, and those who handle disagreement peaceably are ipso facto deficient in their commitment to justice. To restore a belief to the positive value of disagreement, here, would be a challenging task indeed. When Bernard Williams writes of disagreement as “an important and constitutive feature of our relations to others,” he is speaking a moral language that’s incomprehensible to those for whom free speech is so last century and for whom history is always a story of moral progress.

How might such people come to see, with Williams, the virtue of moral and epistemic humility? How might they be brought to see that it can be a positive good to belong to a society in which people with deep disagreements, even about sexuality and personal self-determination, can live in peace with one another and, just possibly, converse? I have absolutely no idea.
