Dorothy L. Sayers, from her essay “Why Work?” (1942):
War is a judgment that overtakes societies when they have been living upon ideas that conflict too violently with the laws governing the universe…. Never think that wars are irrational catastrophes: they happen when wrong ways of thinking and living bring about intolerable situations; and whichever side may be the more outrageous in its aims and the more brutal in its methods, the root causes of conflict are usually to be found in some wrong way of life in which all parties have acquiesced, and for which everybody must, to some extent, bear the blame.
It strikes me that this is equally true of the culture war that Americans have been fighting with one another for quite some time.
