The need to live by secure, sharply etched classifications…

““The need to live by secure, sharply etched classifications is buried deep in the human mind and one of its earliest demands; simplicity allays anxieties by defeating discriminations. Real situations are rarely clear-cut, real feelings often nests of ambivalence. This is something the adult learns to recognize and to tolerate, if he is fortunate; it is a strenuous insight from which he will regress at the first opportunity. That is why the liberal temper, which taught men to live with uncertainties and ambiguities, the most triumphant achievement of nineteenth-century culture, was so vulnerable to the assaults of cruder views of the world, to bigotry, chauvinism, and other coarse and simplistic classifications. "Every society," wrote Friedrich Nietzsche in one of his most brilliant aphorisms, "has the tendency to degrade and, as it were, to starve out, its adversaries—at least in its perception." The criminal, he thought, was one victim of such a regressive process; so was the Jew. And "among artists, the 'philistine and bourgeois' becomes a caricature." And artists, the avant-gardes, Nietzsche might have added, only set the tone for the wider culture. Class consciousness, which emerged fitfully and then more and more fully and aggressively towards the end of the eighteenth and in the early nineteenth century, enshrined such a caricature: a mixture and social reality and unconscious needs.””
