The astounding thing about all the quackeries, fads, and movements of the past hundred years in America is that they were first accepted by superior people, by men and women of education, intelligence, breeding, wealth, and experience. Only after the upper classes had approved, the masses accepted each new thing.
—Gilbert Seldes, The Stammering Century (1928)
Perhaps it’s not that astounding; I long ago observed that high intelligence is not necessarily associated with common sense.
