The two leitmotifs of the present writer's Metapolitics: From the Romantics to Hitler, 1941, were the rival outlooks of Nietzsche, Wagner: Nietzsche as the voice warning Germany against nationalism, anti-Semitism, herd-collectivism; Wagner as the voice teaching Hitler his Aryan racism, anti-parliamentary leadership-cult, anti-aristocratic cult of the collective "folk." . . . Nietzsche's was the only voice in the 1880's to say that Richard Wagner's folk-romanticism and anti-Semitism would make his German nationalist disciples "the destroyers of both German and European culture."
