-162 Cult of the genius out of vanity.\97 Because we think well of ourselves, but \
-nonetheless never suppose ourselves capable of producing a painting like one of\
-Raphael's or a dramatic scene like one of Shakespeare's, we convince ourselves \
-that the capacity to do so is quite extraordinarily marvelous, a wholly \
-uncommon accident, or, if we are still religiously inclined, a mercy from on \
-high. Thus our vanity, our self-love, promotes the cult of the genius: for only\
-if we think of him as being very remote from us, as a miraculum, does he not \
-aggrieve us (even Goethe, who was without envy, called Shakespeare his star of \
-the most distant heights [\"William! Stern der schönsten Ferne\": from Goethe's, \
-\"Between Two Worlds\"]; in regard to which one might recall the lines: \"the \
-stars, these we do not desire\" [from Goethe's, \"Comfort in Tears\"]). But, aside\
-from these suggestions of our vanity, the activity of the genius seems in no \
-way fundamentally different from the activity of the inventor of machines, the \
-scholar of astronomy or history, the master of tactics. All these activities \
-are explicable if one pictures to oneself people whose thinking is active in \
-one direction, who employ everything as material, who always zealously observe \
-their own inner life and that of others, who perceive everywhere models and \
-incentives, who never tire of combining together the means available to them. \
-Genius too does nothing except learn first how to lay bricks then how to build,\
-except continually seek for material and continually form itself around it. \
-Every activity of man is amazingly complicated, not only that of the genius: \
-but none is a \"miracle.\"\97 Whence, then, the belief that genius exists only in \
-the artist, orator and philosopher? that only they have \"intuition\"? (Whereby \
-they are supposed to possess a kind of miraculous eyeglass with which they can \
-see directly into \"the essence of the thing\"!) It is clear that people speak of\
-") _T("\
-genius only where the effects of the great intellect are most pleasant to them \
-and where they have no desire to feel envious. To call someone \"divine\" means: \
-\"here there is no need for us to compete.\" Then, everything finished and \
-complete is regarded with admiration, everything still becoming is undervalued.\
-But no one can see in the work of the artist how it has become; that is its \
-advantage, for wherever one can see the act of becoming one grows somewhat \
-cool. The finished and perfect art of representation repulses all thinking as \
-to how it has become; it tyrannizes as present completeness and perfection. \
-That is why the masters of the art of representation count above all as gifted \
-with genius and why men of science do not. In reality, this evaluation of the \
-former and undervaluation of the latter is only a piece of childishness in the \
-realm of reason. \

- \
-163 The serious workman.\97 Do not talk about giftedness, inborn talents! One can\
-name great men of all kinds who were very little gifted. The acquired \
-greatness, became \"geniuses\" (as we put it), through qualities the lack of \
-which no one who knew what they were would boast of: they all possessed that \
-seriousness of the efficient workman which first learns to construct the parts \
-properly before it ventures to fashion a great whole; they allowed themselves \
-time for it, because they took more pleasure in making the little, secondary \
-things well than in the effect of a dazzling whole. the recipe for becoming a \
-good novelist, for example, is easy to give, but to carry it out presupposes \
-qualities one is accustomed to overlook when one says \"I do not have enough \
-talent.\" One has only to make a hundred or so sketches for novels, none longer \

-one should write down anecdotes each day until one has learned how to give them\

-describing human types and characters; one should above all relate things to \
-others and listen to others relate, keeping one's eyes and ears open for the \
-effect produced on those present, one should travel like a landscape painter or\
-costume designer; one should excerpt for oneself out of the individual sciences\
-everything that will produce an artistic effect when it is well described, one \
-should, finally, reflect on the motives of human actions, disdain no signpost \
-to instruction about them and be a collector of these things by day and night. \
-One should continue in this many-sided exercise some ten years: what is then \
-created in the workshop, however, will be fit to go out into the world.\97 What, \
-however, do most people do? They begin, not with the parts, but with the whole.\
-Perhaps they chance to strike a right note, excite attention and from then on \
-strike worse and worse notes, for good, natural reasons.\97 Sometimes, when the \
-character and intellect needed to formulate such a life-plan are lacking, fate \

-virtue of which they acquire their knowledge by quite other means than the rest\

-of mankind. One ascribes to them, it seems, a direct view of the nature of the \
-world, as it were a hole in the cloak of appearance, and believes that, by \
-virtue of this miraculous seer's vision, they are able to communicate something\
-conclusive and decisive about man and the world without the toil and \
-rigorousness required by science. As long as there continue to be those who \
-believe in the miraculous in the domain of knowledge one can perhaps concede \
-that these people themselves derive some benefit from their belief, inasmuch as\
-through their unconditional subjection to the great spirits they create for \
-their own spirit during its time of development the finest form of discipline \
-and schooling. On the other hand, it is at least questionable whether the \
-superstitious belief in genius, in its privileges and special abilities, is of \
-benefit to the genius himself if it takes root in him. It is in any event a \
-dangerous sign when a man is assailed by awe of himself, whether it be the \
-celebrated Caesar's awe of Caesar or the awe of one's own genius now under \
-consideration; when the sacrificial incense which is properly rendered only to \
-a god penetrates the brain of the genius, so that his head begins to swim and \
-he comes to regard himself as something supra-human. The consequences that \
-slowly result are: the feeling of irresponsibility, of exceptional rights, the \
-belief that he confers a favor by his mere presence, insane rage when anyone \
-attempts even to compare him with others, let alone to rate him beneath them, \
-or to draw attention to lapses in his work. Because he ceases to practice \
-criticism of himself, at last one pinion after the other falls out of his \
-plumage: that superstitious eats at the roots of his powers and perhaps even \
-turns him into a hypocrite after his powers have fled from him. For the great \

-insight into the nature and origin of their powers, if they grasp, that is to \
-say, what purely human qualities have come together in them and what fortunate \
-circumstances attended them: in the first place undiminished energy, resolute \
-application to individual goals, great personal courage, then the good fortune \
-to receive an upbringing which offered in the early years the finest teachers, \
-models and methods. To be sure, when their goal is the production of the \
-greatest possible effect, unclarity with regard to oneself and that \
-semi-insanity superadded to it has always achieved much; for what has been \
-admired and envied at all times has been that power in them by virtue of which \
-they render men will-less and sweep them away into the delusion that the \
-leaders they are following are supra-natural. Indeed, it elevates and inspires \
-men to believe that someone is in possession of supra-natural powers: to this \
-extent Plato was right to say [Plato: Phaedrus, 244a] that madness has brought \
-the greatest of blessings upon mankind.\97 In rare individual cases this portion \
-of madness may, indeed, actually have been the means by which such a nature, \
-excessive in all directions, was held firmly together: in the life of \
-individuals, too, illusions that are in themselves poisons often play the role \
-of healers; yet, in the end, in the case of every \"genius\" who believes in his \
-own divinity the poison shows itself to the same degree as his \"genius\" grows \
-old: one may recall, for example, the case of Napoleon, whose nature certainly \
-grew into the mighty unity that sets him apart from all men of modern times \
-precisely through his belief in himself and his star and through the contempt \
-for men that flowed from it; until in the end, however, this same belief went \
-over into an almost insane fatalism, robbed him of his acuteness and swiftness \
-of perception, and became the cause of his destruction. \
