In his private papers, Spengler denounced Nazi anti-Semitism in even stronger terms, wondering "how much envy of the capability of other people in view of one's lack of it lies hidden in anti-Semitism!", and arguing that "when one would rather destroy business and scholarship than see Jews in them, one is an ideologue, i.e., a danger for the nation. Idiotic." Spengler was an admirer of the old Prussian aristocracy and showed contempt for the proletarian and demagogic character of the Nazi party, and considered the Aryan racial doctrine to be nonsense. In 1934, Spengler pronounced the funeral oration for one of the victims of the Night of the Long Knives and retired in 1935 from the board of the highly influential Nietzsche Archive in opposition to the regime.
