Sobre la utilidad y el perjuicio de la historia para la vida

Preface "Moreover I hate everything that merely instructs me without increasing or directly quickening my activity." These words of Goethe, like a sincere ceterum censeo may well stand at the head of my thoughts on the worth and the worthlessness of history. I will show in them why instruction that does not "quicken," knowledge that slackens the rein of activity, why in fact history, in Goethe's phrase, must be seriously "hated," as a costly and superfluous luxury of the understanding: for we are still in want of the necessaries of life, and the superfluous is an enemy to the necessary. We do need history, but quite differently from the jaded idlers in the garden of knowledge, however grandly they may look down on our rude and unpicturesque requirements. In other words, we need it for life and action, not as a convenient way to avoid life and action, or to excuse a selfish life and a cowardly or base action. We would serve history only so far as it serves life; but to value its study beyond a certain point mutilates and degrades life: and this is a fact that certain marked symptoms of our time make it as necessary as it may be painful to bring to the test of experience. I have tried to describe a feeling that has often troubled me: I revenge myself on it by giving it publicity. This may lead some one to explain to me that he has also had the feeling, but that I do not feel it purely and elementally enough, and cannot express it with the ripe certainty of experience. A few may say so; but most people will tell me that it is a perverted, unnatural, horrible, and altogether unlawful feeling to have, and that I show myself unworthy of the great historical movement which is especially strong among the German people for the last two generations.…
