“The genius continually discovers fate, and the more profound the genius, the more profound the discovery of fate. To spiritlessness, this is naturally foolishness, but in actuality it is greatness, because no man is born with the idea of providence, and those who think that one acquires it gradually though education are greatly mistaken, although I do not thereby deny the significance of education. Not until sin is reached is providence posited. Therefore the genius has an enormous struggle to reach providence. If he does not reach it, truly he becomes a subject for the study of fate. The genius is an omnipotent Ansich [in itself] which as such would rock the whole world. For the sake of order, another figure appears along with him, namely fate. Fate is nothing. It is the genius himself who discovers it, and the more profound the genius, the more profoundly he discovers fate, because that figure is merely the anticipation of providence. If he continues to be merely a genius and turns outward, he will accomplish astonishing things; nevertheless, he will always succumb to fate, if not outwardly, so that it is tangible and visible to all, then inwardly. Therefore, a genius-existence is always like a fairy tale if in the deepest sense the genius does not turn inward into himself. The genius is able to do all things, and yet he is dependent upon an insignificance that no one comprehends, an insignificance upon which the genius himself by his omnipotence bestows omnipotent significance. Therefore, a second lieutenant, if he is a genius, is able to become an emperor and change the world, so that there becomes one empire and one emperor. But therefore, too, the army may be drawn up for battle, the conditions for the battle absolutely favorable, and yet in the next moment wasted; a kingdom of heroes may plead that the order for battle be given-but he cannot; he must wait for the fourteenth of June. And why? Because that was the date of the battle of Marengo. So all things may be in readiness, he himself stands before the legions, waiting only for the sun to rise in order to announce the time for the oration that will electrify the soldiers, and the sun may rise more glorious than ever, an inspiring and inflaming sight for all, only not for him, because the sun did not rise as glorious as this at Austerlitz, and only the sun of Austerlitz gives victory and inspiration. Thus, the inexplicable passion with which such a one may often rage against an entirely insignificant man, when otherwise he may show humanity and kindness even toward his enemies. Yes, woe unto the man, woe unto the woman, woe unto the innocent child, woe unto the beast of the field, woe unto the bird whose flight, woe unto the tree whose branch comes in his way at the moment he is to interpret his omen.”

Parce que vous êtes un grand seigneur, vous vous croyez un grand génie! … vous vous êtes donné la peine de naître, et rien de plus. Du reste homme assez ordinaire!
Act II, scene ii
The Marriage of Figaro (1778)

Einen Menschen verstehen heißt also: auch er sein. Der geniale Mensch aber offenbarte sich an jenen Beispielen eben als der Mensch, welcher ungleich mehr Wesen versteht als der mittelmäßige. Goethe soll von sich gesagt haben, es gebe kein Laster und kein Verbrechen, zu dem er nicht die Anlage in sich verspürt, das er nicht in irgend einem Zeitpunkte seines Lebens vollauf verstanden habe. Der geniale Mensch ist also komplizierter, zusammengesetzter, reicher; und ein Mensch ist um so genialer zu nennen, je mehr Menschen er in sich vereinigt, und zwar, wie hinzugefügt werden muß, je lebendiger, mit je größerer Intensität er die anderen Menschen in sich hat.

Genius is a form of madness and we're all that way. But I used to be coy about it, like me guitar playing. But if there's such a thing as genius — I am one. And if there isn't, I don't care.
