The Use and Abuse of History by Friedrich Nietzsche

The fact that life does need the service of history must be as clearly grasped as that an excess of history hurts it; this will be proved later. History is necessary to the living man in three ways: in relation to his action and struggle, his conservatism and reverence, his suffering and his desire for deliverance. These three relations answer to the three kinds of history -- so far as they can be distinguished -- the _monumental_, the _antiquarian_, and the _critical_.

History is necessary above all to the man of action and power who fights a great fight and needs examples, teachers and comforters; he cannot find them among his contemporaries. It was necessary in this sense to Schiller; for our time is so evil, Goethe says, that the poet meets no nature that will profit him, among living men. Polybius is thinking of the active man when he calls political history the true preparation for governing a state; it is the great teacher, that shows us how to bear steadfastly the reverses of fortune, by reminding us of what others have suffered. Whoever has learned to recognise this meaning in history must hate to see curious tourists and laborious beetle-hunters climbing up the great pyramids of antiquity. He does not wish to meet the idler who is rushing through the picture-galleries of the past for a new distraction or sensation, where he himself is looking for example and encouragement.
