_You can only explain the past by what is highest in the present._ Only by straining the noblest qualities you have to their highest power will you find out what is greatest in the past, most worth knowing and preserving. Like by like! otherwise you will draw the past to your own level. Do not believe any history that does not spring from the mind of a rare spirit. You will know the quality of the spirit, by its being forced to say something universal, or to repeat something that is known already; the fine historian must have the power of coining the known into a thing never heard before and proclaiming the universal so simply and profoundly that the simple is lost in the profound, and the profound in the simple. No one can be a great historian and artist, and a shallowpate at the same time. But one must not despise the workers who sift and cast together the material because they can never become great historians. They must, still less, be confounded with them, for they are the necessary bricklayers and apprentices in the service of the master: just as the French used to speak, more naïvely than a German would, of the "historiens de M. Thiers." These workmen should gradually become extremely learned, but never, for that reason, turn to be masters. Great learning and great shallowness go together very well under one hat. Thus, history is to be written by the man of experience and character. He who has not lived through something greater and nobler than others, will not be able to explain anything great and noble in the past. The language of the past is always oracular: you will only understand it as builders of the future who know the present. We can only explain the extraordinarily wide influence of Delphi by the fact that the Delphic priests had an exact knowledge of the past: and, similarly, only he who is building up the future has a right to judge the past. If you set a great aim before your eyes, you control at the same time the itch for analysis that makes the present into a desert for you, and all rest, all peaceful growth and ripening, impossible. Hedge yourselves with a great, all-embracing hope, and strive on. Make of yourselves a mirror where the future may see itself, and forget the superstition that you are Epigoni. You have enough to ponder and find out, in pondering the life of the future: but do not ask history to show you the means and the instrument to it. If you live yourselves back into the history of great men, you will find in it the high command to come to maturity and leave that blighting system of cultivation offered by your time: which sees its own profit in not allowing you to become ripe, that it may use and dominate you while you are yet unripe. And if you want biographies, do not look for those with the legend "Mr. So-and-so and his times," but for one whose title-page might be inscribed "a fighter against his time." Feast your souls on Plutarch, and dare to believe in yourselves when you believe in his heroes.
