Address by His Highness the Aga Khan at the Leadership and Diversity Conference, Gatineau, Canada (19 May 2004)

Attributed to Nietzsche on quotes sites and on social media, the original quotation is from An Introduction to the History of Psychology by B. R. Hergenhahn (2008, page 226) and is the author's summary of Nietzsche's ideas: "The meaning and morality of one's life come from within oneself. Healthy, strong individuals seek self-expansion by experimenting, by living dangerously. Life consists of an almost infinite number of possibilities, and the healthy person (the superman) explores as many of them as possible. Religions or philosophies that teach pity, humility, submissiveness, self-contempt, self-restraint, guilt, or a sense of community are simply incorrect. [...] For Nietzsche, the good life is ever-changing, challenging, devoid of regret, intense, creative, and risky."

Nochmals gesagt, heute ist es mir ein unmögliches Buch, - ich heisse es schlecht geschrieben, schwerfällig, peinlich, bilderwüthig und bilderwirrig, gefühlsam, hier und da verzuckert bis zum Femininischen, ungleich im Tempo, ohne Willen zur logischen Sauberkeit, sehr überzeugt und deshalb des Beweisens sich überhebend, misstrauisch selbst gegen die Schicklichkeit des Beweisens, als Buch für Eingeweihte, als "Musik" für Solche, die auf Musik getauft, die auf gemeinsame und seltene Kunst-Erfahrungen hin von Anfang der Dinge an verbunden sind, als Erkennungszeichen für Blutsverwandte in artibus, - ein hochmüthiges und schwärmerisches Buch, das sich gegen das profanum vulgus der "Gebildeten" von vornherein noch mehr als gegen das "Volk" abschliesst, welches aber, wie seine Wirkung bewies und beweist, sich gut genug auch darauf verstehen muss, sich seine Mitschwärmer zu suchen und sie auf neue Schleichwege und Tanzplätze zu locken.

In diesen Sanct-Johann- und Sanct-Veittänzern erkennen wir die bacchischen Chöre der Griechen wieder, mit ihrer Vorgeschichte in Kleinasien, bis hin zu Babylon und den orgiastischen Sakäen. Es giebt Menschen, die, aus Mangel an Erfahrung oder aus Stumpfsinn, sich von solchen Erscheinungen wie von "Volkskrankheiten", spöttisch oder bedauernd im Gefühl der eigenen Gesundheit abwenden: die Armen ahnen freilich nicht, wie leichenfarbig und gespenstisch eben diese ihre "Gesundheit" sich ausnimmt, wenn an ihnen das glühende Leben dionysischer Schwärmer vorüberbraust.
