The Use and Abuse of History by Friedrich Nietzsche

This is how history can serve life. Every man and nation needs a certain knowledge of the past, whether it be through monumental, antiquarian, or critical history, according to his objects, powers, and necessities. The need is not that of the mere thinkers who only look on at life, or the few who desire knowledge and can only be satisfied with knowledge; but it has always a reference to the end of life, and is under its absolute rule and direction. This is the natural relation of an age, a culture and a people to history; hunger is its source, necessity its norm, the inner plastic power assigns its limits. The knowledge of the past is only desired for the service of the future and the present, not to weaken the present or undermine a living future. All this is as simple as truth itself, and quite convincing to any one who is not in the toils of "historical deduction."

And now to take a quick glance at our time! We fly back in astonishment. The clearness, naturalness, and purity of the connection between life and history has vanished; and in what a maze of exaggeration and contradiction do we now see the problem! Is the guilt ours who see it, or have life and history really altered their conjunction and an inauspicious star risen between them? Others may prove we have seen falsely; I am merely saying what we believe we see. There is such a star, a bright and lordly star, and the conjunction is really altered -- by science, and the demand for history to be a science. Life is no more dominant, and knowledge of the past no longer its thrall: boundary marks are overthrown everything bursts its limits. The perspective of events is blurred, and the blur extends through their whole immeasurable course.
