Nach Alfred Rosenberg: Die Protokolle der Weisen von Zion und die jüdische Weltpolitik. 1923. Online-Fassung (Memento vom 14. Juli 2011 im Internet Archive). Zur Bedeutung des Buches von Heise in verschwörungstheoretischen Kreisen s. auch Daniel Pipes, Conspiracy: How the Paranoid Style Flourishes and Where It Comes from, 1997, S. 101: “These ideas (i. e. fear of freemasonry) were then stoked by some powerful books. Friedrich Wichtl’s World Freemasonry – World Revolution – World Republic, ‚the best-known and most influential work to propagate an antimasonic conspiracy theory myth‘, came out in 1919 and had an ‚astonishing diffusion‘. Also in that year appeared the important screed by Karl Heise, Entente, Freemasonry and World War. […] The Nazis subscribed to secret society myths; after Jews, Freemasonry were the second group to be persecuted. Still they were second, turning up in Hitler’s public statements mainly as an instrument of Jewry’s world conspiracy. ‚Semitic Freemasons were the main agitators of [First] World War. Secretly concealed Masonry is Jewry’s best weapon‘. The verbal assault began even before 1933, and so active were the security services' antimasonic units that by August 1935 the party newspapers could announce ‚the end of Freemasonry in Germany‘.”
