It is necessary for us to explain the involuntary repugnance we possess for the nature and personality of the Jews. The Jews have never produced a true poet. Heinrich Heine reached the point where he duped himself into a poet, and was rewarded by his versified lies being set to music by our own composers. He was the conscience of Judaism, just as Judaism is the evil conscience of our modern civilization.
