"Except for Christianity, the Nazis reject as Jewish everything which stems from Jewish authors. This condemnation includes the writings of those Jews who, like Stahl, Lassalle, Gumplowicz, and Rathenau, have contributed many essential ideas to the system of Nazism. But the Jewish mind is, as the Nazis say, not limited to the Jews and their offspring only. Many "Aryans" have been imbued with Jewish mentality--for instance the poet, writer, and critic Gotthold Ephraim Lessing, the socialist Frederick Engels, the composer Johannes Brahms, the writer Thomas Mann, and the theologian Karl Barth. They too are damned. Then there are whole schools of thought, art, and literature rejected as Jewish. Internationalism and pacifism are Jewish, but so is warmongering. So are liberalism and capitalism, as well as the "spurious" socialism of the Marxians and of the Bolsheviks. The epithets Jewish and Western are applied to the philosophies of Descartes and Hume, to positivism, materialism and empiro-criticism, to the economic theories both of the classics and of modern subjectivism. Atonal music, the Italian opera style, the operetta and the paintings of impressionism are also Jewish. In short, Jewish is what any Nazi dislikes. If one put together everything that various Nazis have stigmatized as Jewish, one would get the impression that our whole civilization has been the achievement only of Jews."
