Sec. 283; Variant translation: For believe me: the secret for harvesting from existence the greatest fruitfulness and greatest enjoyment is — to live dangerously.
The Gay Science (1882)
Context: For believe me! — the secret for harvesting from existence the greatest fruitfulness and the greatest enjoyment is: to live dangerously! Build your cities on the slopes of Vesuvius! Send your ships into uncharted seas! Live at war with your peers and yourselves! Be robbers and conquerors as long as you cannot be rulers and possessors, you seekers of knowledge! Soon the age will be past when you could be content to live hidden in forests like shy deer! At long last the search for knowledge will reach out for its due: — it will want to rule and possess, and you with it!

This changeful life has slipped away”

A smile of joy since I was born
In secret pleasure — secret tears
This changeful life has slipped away
As friendless after eighteen years
As lone as on my natal day

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.
