“In the Far West, the United States of America openly claimed to be custodians of the whole planet. Universally feared and envied, universally respected for their enterprise, yet for their complacency very widely despised, the Americans were rapidly changing the whole character of man’s existence. By this time every human being throughout the planet made use of American products, and there was no region where American capital did not support local labour. Moreover the American press, gramophone, radio, cinematograph and televisor ceaselessly drenched the planet with American thought. Year by year the aether reverberated with echoes of New York’s pleasures and the religious fervours of the Middle West. What wonder, then, that America, even while she was despised, irresistibly moulded the whole human race. This, perhaps, would not have mattered, had America been able to give of her very rare best. But inevitably only her worst could be propagated. Only the most vulgar traits of that potentially great people could get through into the minds of foreigners by means of these crude instruments. And so, by the floods of poison issuing from this people’s baser members, the whole world, and with it the nobler parts of America herself, were irrevocably corrupted.
For the best of America was too weak to withstand the worst. Americans had indeed contributed amply to human thought. They had helped to emancipate philosophy from ancient fetters. They had served science by lavish and rigorous research. In astronomy, favoured by their costly instruments and clear atmosphere, they had done much to reveal the dispositions of the stars and galaxies. In literature, though often they behaved as barbarians, they had also conceived new modes of expression, and moods of thought not easily appreciated in Europe. They had also created a new and brilliant architecture. And their genius for organization worked upon a scale that was scarcely conceivable, let alone practicable, to other peoples. In fact their best minds faced old problems of theory and of valuation with a fresh innocence and courage, so that fogs of superstition were cleared away wherever these choice Americans were present. But these best were after all a minority in a huge wilderness of opinionated self-deceivers, in whom, surprisingly, an outworn religious dogma was championed with the intolerant optimism of youth. For this was essentially a race of bright, but arrested, adolescents. Something lacked which should have enabled them to grow up. One who looks back across the aeons to this remote people can see their fate already woven of their circumstance and their disposition, and can appreciate the grim jest that these, who seemed to themselves gifted to rejuvenate the planet, should have plunged it, inevitably, through spiritual desolation into senility and age-long night.”
