“Experience teaches only the teachable.”

“„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.”

“It's a very salutary thing to realize that the rather dull universe in which most of us spend most of our time is not the only universe there is. I think it's healthy that people should have this experience.”

“That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.”

“Words form the thread on which we string our experiences.”

“Experience is not what happens to a man; it is what a man does with what happens to him.”

“My mind is so busy thinking about values that I don't have time to experience them.”
