We do live in a world where one has to be able to maintain a hierarchy of tragedies in order to function. You can’t try to save the world from the ravages of runaway climate change without being reminded that there are poor people for whom energy insecurity is already bad enough. You can’t try to defend Ukraine without being reminded that Russia faces NATO expansion right up to its borders. You can’t try to feed a single mouth in Africa without being reminded that there are homeless vets in the US. We can’t pretend that we’re in a world where justice is a determined state that can be achieved by some discrete number of moves. You need to be able to maintain a hierarchy of tragedies. You need to be able to decide which wrong to commit.
