Cosmopolitanism vs. nationalism

That is the topic of my latest Bloomberg column.  It is hard to excerpt, but here is the closing bit:

The best way for that to happen is to let practical nationalism reign, while at the margin seeking to soften it with moral cosmopolitanism. Both perspectives are valuable, and neither can be allowed to dominate. Each perspective, standing on its own, is intellectually vulnerable, yet the two outlooks together are not quite fully harmonious. It is this dynamic clash, however, that helps to account for the strength of each.

Try explaining all that, and its required background knowledge, in a 280-word tweet. Yet much of the world manages a pretty fruitful balance between moral cosmopolitanism and practical nationalism. There is a wisdom embodied in this lived experience which neither pundits nor philosophers can convey.

A tempered and centrist cosmopolitanism won’t always command the strongest loyalties, nor will practical nationalism always look so pretty. If we can accept that reality, then maybe we can stop throwing stones at each other.
