“La philosophie nous enseigne à douter de ce qui nous paraît évident. La propagande, au contraire, nous enseigne à accepter pour évident ce dont il serait raisonnable de douter.”
En anglais : "„All effective propaganda“, Hitler wrote, „must be expressed in a few stereotyped formulas.“ The stereotyped formulas must be constantly repeated for „only constant repetition will finally succeed in im printing an idea upon the memory of a crowd.“ Philosophy teaches us to feel uncertain about the things that seems to us self-evident. Propaganda, on the other hand, teaches us to accept as self-evident matters about which it would be reasonable to suspend our judgement or to feel doubt."
