How does modernity imply monoculture?<p>As to diversity (and equity, and inclusion?) of cultures, I'm all for having multiple cultures —the salad, not the oatmeal, model–; the trick seems to be keeping things so that everyone can voluntarily pass between cultures? (compare the EU four freedoms? or the Partition of India for how not to do it?)<p>As for the overall handwringing about drift and decay, a footnote:<p>Körner, The Pleasures of Counting (1996)<p>> <i>† Social Darwinism applies the Darwinian doctrine of the survival of the fittest to human society. Rich social Darwinists take wealth as the best indication of fitness to survive, academic social Darwinists take intellectual achievements as the best indication and so on. They are often haunted by the fear that the unfit do not understand this and may outbreed the fit.</i>
