From an interview on Indiana Public Radio:
If you understand your own place and its intricacy and the possibility of affection and good care of it, then imaginatively you recognize that possibility for other places and other people, so that if you wish well to your own place, and you recognize that your own place is a part of the world, then this requires a well-wishing toward the whole world.
In return you hope for the world’s well-wishing toward your place.
And this is a different impulse from the impulse of nationalism. This is what I would call patriotism: the love of a home country that’s usually much smaller than a nation.
