La decadencia de Occidente
Among the most important German writers were Thomas Mann (1875–1955), Hermann Hesse (1877–1962) and Bertolt Brecht (1898–1956). The reactionary historian Oswald Spengler wrote "The Decline of the West" (1918–23) on the inevitable decay of Western Civilization, and influenced intellectuals in Germany such as Martin Heidegger, Max Scheler, and the Frankfurt School, as well as intellectuals around the world.
