“The art of reading and studying consists in remembering the essentials and forgetting what is not essential.”

“The very first essential for success is a perpetually constant and regular employment of violence.”

“I am firmly convinced to-day that, generally speaking, it is in youth that men lay the essential groundwork of their creative thought, wherever that creative thought exists. I make a distinction between the wisdom of age- which can only arise from the greater profundity and foresight that are based on the experiences of a long life- and the creative genius of youth, which blossoms out in thoughts and ideas with inexhaustible fertility, without being able to put these into practice immediately, because of their very superabundance. These furnish the building materials and plans for the future; and it is from them that age takes the stones and builds the edifice, unless the so-called wisdom of the years may have smothered the creative genius of youth.”

“The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.”

“Reading is not an end to itself, but a means to an end.”

“Instruction in world history in the so-called high schools is even today in a very sorry condition. Few teachers understand that the study of history can never be to learn historical dates and events by heart and recite them by rote; that what matters is not whether the child knows exactly when this battle or that was fought, when a general was born, or even when a monarch (usually a very insignificant one) came into the crown of his forefathers. No, by the living God, this is very unimportant. To 'learn' history means to seek and find the forces which are the causes leading to those effects which we subsequently perceive as historical events.”

“Im allgemeinen soll aber nie vergessen werden, daß nicht die Erhaltung eines Staates oder gar die einer Regierung höchster Zweck des Daseins der Menschen ist, sondern die Bewahrung ihrer Art.”
