Source: Judaism in Music
“The Jew has never had an art of his own, hence never a live of art-enabling import... "So long as the separate art of music had a real organic life-need in it, down to the epochs of Mozart and Beethoven, there was nowhere to be found a Jew composer: it was utterly impossible for an element quiet foreign to that living organism to take a part in the formative stages of that life. Only when a body's inner death is manifest, do outside elements win the power of judgment in it - yet merely to destroy it.
On one thing am I clear: that is the influence which the Jews have gained upon our mental life, as displayed in the deflection and falsification of our highest culture-tendencies. Whether the downfall of our culture can be arrested by a violent rejection of the destructive alien element, I an unable to decide, since that would require forces with whose existence I am unacquainted.”
