The Use and Abuse of History by Friedrich Nietzsche

The unrestrained historical sense, pushed to its logical extreme, uproots the future, because it destroys illusions and robs existing things of the only atmosphere in which they can live. Historical justice, even if practised conscientiously, with a pure heart, is therefore a dreadful virtue, because it always undermines and ruins the living thing: its judgment always means annihilation. If there be no constructive impulse behind the historical one, if the clearance of rubbish be not merely to leave the ground free for the hopeful living future to build its house, if justice alone be supreme, the creative instinct is sapped and discouraged. A religion, for example, that has to be turned into a matter of historical knowledge by the power of pure justice, and to be scientifically studied throughout, is destroyed at the end of it all. For the historical audit brings so much to light which is false and absurd, violent and inhuman, that the condition of pious illusion falls to pieces.

And a thing can only live through a pious illusion. For man is creative only through love and in the shadow of love's illusions, only through the unconditional belief in perfection and righteousness. Everything that forces a man to be no longer unconditioned in his love, cuts at the root of his strength: he must wither, and be dishonoured. Art has the opposite effect to history: and only perhaps if history suffer transformation into a pure work of art, can it preserve instincts or arouse them.
