"Oswald Arnold Gottfried Spengler" was a German historian and Philosophy of history/philosopher of history whose interests included mathematics, science, and art. He is best known for his book The Decline of the West (Der Untergang des Abendlandes), published in 1918 and 1922, covering all of world history. [https://en.wikipedia.org/w/index.php?title=Spengler%27s_civilization_model&oldid=571085146 Spengler's civilization model] postulates that any civilization is a superorganism with a limited lifespan.
He wrote extensively throughout World War I and the interwar period, and supported German hegemony in Europe. His other writings made little impact outside Germany. In 1920 Spengler produced Preussentum und Sozialismus/Prussiandom and Socialism (Preußentum und Sozialismus), which argued for an organic, nationalist brand of socialism and authoritarianism. Some Nazi Germany/Nazis, including Joseph Goebbels, saw Spengler as an intellectual precursor, but he was ultimately ostracised by the Nazis in 1933 for his pessimism about the future of Germany and Europe, his refusal to support Racial policy of Nazi Germany/Nazi ideas of Master race/racial superiority, and his critical work The Hour of Decision.If you enjoy these quotes, be sure to check out other famous philosophers!
