Nietzsche points out, in his early essay upon the study of history, that humanity is much too prone to consider itself historically. That is to say, there is too much tendency to consider man as he has seemed rather than man as he has been--to dwell upon creeds and manifestoes rather than upon individual and racial motives, characters and instincts.[3] The result is that history piles up misleading and useless records and draws erroneous conclusions from them. As a science in itself, it bears but three useful aspects--the monumental, the antiquarian and the critical. Its true monuments are not the constitutions and creeds of the past--for these, as we have seen, are always artificial and unnatural--but the great men of the past--those fearless free spirits who achieved immortality by their courage and success in pitting their own instincts against the morality of the majority. Such men, he says, are the only human beings whose existence is of interest to posterity. "They live together as timeless contemporaries:" they are the landmarks along the weary road the human race has traversed. In its antiquarian aspect, history affords us proof that the world is progressing, and so gives the men of the present a definite purpose and justifiable enthusiasm. In its critical aspect, history enables us to avoid the delusions of the past, and indicates to us the broad lines of evolution. Unless we have in mind some definite program of advancement, he says, all learning is useless. History, which merely accumulates records, without "an ideal of humanistic culture" always in mind, is mere pedantry and scholasticism. All education, says Nietzsche, may be regarded as a continuation of the process of breeding.[4] The two have the same object: that of producing beings capable of surviving in the struggle for existence. A great many critics of Nietzsche have insisted that since the struggle for existence means a purely physical contest, he is in error, for education does not visibly increase a man's chest expansion or his capacity for lifting heavy weights. But it is obvious none the less that a man who sees things as they are, and properly estimates the world about him, is far better fitted to achieve some measure of mastery over his environment than the man who is a slave to delusions. Of two men, one of whom believes that the moon is made of green cheese and that it is possible to cure smallpox by merely denying that it exists, and the other of whom harbors no such superstitions, it is plain that the latter is more apt to live long and acquire power.
