Adolf Hitler,

“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.”
