Wie finden wir uns selbst wieder? Wie kann sich der Mensch kennen? Er ist eine dunkle und verhüllte Sache; und wenn der Hase sieben Häute hat, so kann der Mensch sich sieben mal siebzig abziehn und wird noch nicht sagen können: »das bist du nun wirklich, das ist nicht mehr Schale«.
“Schopenhauer as educator,” § 3.1, R. Hollingdale, trans. (1983), p. 129
Untimely Meditations (1876)

“We imagine that hardness, violence, slavery, peril in the street and in the heart, concealment, Stoicism, temptation, and deviltry of every sort, everything evil, frightful, tyrannical, raptor- and snake-like in man, serves as well for the advancement of the species "man" as their opposite.”

“We still do not yet know where the drive for truth comes from. For so far we have heard only of the duty which society imposes in order to exist: to be truthful means to employ the usual metaphors. Thus, to express it morally, this is the duty to lie according to a fixed convention, to lie with the herd and in a manner binding upon everyone. Now man of course forgets that this is the way things stand for him. Thus he lies in the manner indicated, unconsciously and in accordance with habits which are centuries' old; and precisely by means of this unconsciousness and forgetfulness he arrives at his sense of truth.”

Friedrich Nietzsche

On Truth and Lie in an Extra-Moral Sense (1873)

“I always believed that at some time fate would take from me the terrible effort and duty of educating myself. I believed that, when the time came, I would discover a philosopher to educate me, a true philosopher whom one could follow without any misgiving because one would have more faith in him than one had in oneself. Then I asked myself: what would be the principles by which he would educate you?—and I reflected on what he might say about the two educational maxims which are being hatched in our time. One of them demands that the educator should quickly recognize the real strength of his pupil and then direct all his efforts and energy and heat at them so as to help that one virtue to attain true maturity and fruitfulness. The other maxim, on the contrary, requires that the educator should draw forth and nourish all the forces which exist in his pupil and bring them to a harmonious relationship with one another. … But where do we discover a harmonious whole at all, a simultaneous sounding of many voice in one nature, if not in such men as Cellini, men in whom everything, knowledge, desire, love, hate, strives towards a central point, a root force, and where a harmonious system is constructed through the compelling domination of this living centre? And so perhaps these two maxims are not opposites at all? Perhaps the one simply says that man should have a center and the other than he should also have a periphery? That educating philosopher of whom I dreamed would, I came to think, not only discover the central force, he would also know how to prevent its acting destructively on the other forces: his educational task would, it seemed to me, be to mould the whole man into a living solar and planetary system and to understand its higher laws of motion.”

Untimely Meditations (1876)

“That every will must consider every other will its equal — would be a principle hostile to life, an agent of the dissolution and destruction of man, an attempt to assassinate the future of man, a sign of weariness, a secret path to nothingness.”

Friedrich Nietzsche book On the Genealogy of Morality

Essay 2, Section 11
On the Genealogy of Morality (1887)

“[I am dynamite]I know my fate. One day my name will be associated with the memory of something tremendous — a crisis without equal on earth, the most profound collision of conscience, a decision that was conjured up against everything that had been believed, demanded, hallowed so far. I am no man, I am dynamite.”

“Freedom means that the manly instincts which delight in war and victory dominate over other instincts, for example, over those of "pleasure." The human being who has become free — and how much more the spirit who has become free — spits on the contemptible type of well-being dreamed of by shopkeepers, Christians, cows, females, Englishmen, and other democrats. The free man is a warrior. —”

Friedrich Nietzsche book Twilight of the Idols

Twilight of the Idols (1888)

“Where there have been powerful governments, societies, religions, public opinions, in short wherever there has been tyranny, there the solitary philosopher has been hated; for philosophy offers an asylum to a man into which no tyranny can force it way, the inward cave, the labyrinth of the heart.”

Untimely Meditations (1876)

“Whoever has overthrown an existing law of custom has hitherto always first been accounted a bad man: but when, as did happen, the law could not afterwards be reinstated and this fact was accepted, the predicate gradually changed: - history treats almost exclusively of these bad men who subsequently became good men!”

Daybreak — Thoughts on the Prejudices of Morality (1881)

“But what changes come upon the weary desert of our culture, so darkly described, when it is touched by the magic of Dionysus! A storm seizes everything decrepit, rotten, broken, stunted; shrouds it in a whirling red cloud of dust and carries it into the air like a vulture. In vain confusion we seek for all that has vanished; for what we see has risen as if from beneath he earth into the gold light, so full and green, so luxuriantly alive, immeasurable and filled with yearning. Tragedy sits in sublime rapture amidst this abundance of life, suffering and delight, listening to a far-off, melancholy song which tells of the Mothers of Being, whose names are Delusion, Will, Woe. -
Yes, my friends, join me in my faith in this Dionysiac life and the rebirth of tragedy. The age of Socratic man is past: crown yourselves with ivy, grasp the thyrsus and do not be amazed if tigers and panthers lie down fawning at your feet. Now dare to be tragic men, for you will be redeemed. You shall join the Dionysiac procession from India to Greece! Gird yourselves for a hard battle, but have faith in the miracles of your god!”

Friedrich Nietzsche book The Birth of Tragedy

Aber wie verändert sich plötzlich jene eben so düster geschilderte Wildniss unserer ermüdeten Cultur, wenn sie der dionysische Zauber berührt! Ein Sturmwind packt alles Abgelebte, Morsche, Zerbrochne, Verkümmerte, hüllt es wirbelnd in eine rothe Staubwolke und trägt es wie ein Geier in die Lüfte. Verwirrt suchen unsere Blicke nach dem Entschwundenen: denn was sie sehen, ist wie aus einer Versenkung an's goldne Licht gestiegen, so voll und grün, so üppig lebendig, so sehnsuchtsvoll unermesslich. Die Tragödie sitzt inmitten dieses Ueberflusses an Leben, Leid und Lust, in erhabener Entzückung, sie horcht einem fernen schwermüthigen Gesange - er erzählt von den Müttern des Seins, deren Namen lauten: Wahn, Wille, Wehe.
Ja, meine Freunde, glaubt mit mir an das dionysische Leben und an die Wiedergeburt der Tragödie. Die Zeit des sokratischen Menschen ist vorüber: kränzt euch mit Epheu, nehmt den Thyrsusstab zur Hand und wundert euch nicht, wenn Tiger und Panther sich schmeichelnd zu euren Knien niederlegen. Jetzt wagt es nur, tragische Menschen zu sein: denn ihr sollt erlöst werden. Ihr sollt den dionysischen Festzug von Indien nach Griechenland geleiten! Rüstet euch zu hartem Streite, aber glaubt an die Wunder eures Gottes!
