History in the USA
Progressivists did not choose to understand other societies in those societies' terms, but, rather, chose to hold them to the standards of the nineteenth-century scientific method. By making that method the criterion of all truth and goodness, the progressivists necessarily ruled out other worldviews as false and bad. By the nineteenth century their victory was so complete that other views now seemed merely irrational, superstitious, trivial.
