Facta! Yes, Facta ficta! - A historian has to do, not with what actually happened, but only with events supposed to have happened: for only the latter have produced an effect. Likewise only with supposed heroes. His theme, so-called world history, is opinions about supposed actions and their supposed motives, which in turn give rise to further opinions and actions, the reality of which is however at once vaporised again and produces an effect only as vapour - a continual generation and pregnancy of phantoms over the impentetrable mist of unfathomable reality. All historians speak of things which have never existed except in imagination.
