Beyond Good and Evil: Prelude to a Philosophy of the Future (German:
Jenseits von Gut und Böse: Vorspiel einer Philosophie der Zukunft) is a book
by philosopher Friedrich Nietzsche that covers ideas in his previous work
Thus Spoke Zarathustra but with a more polemical approach. It was first
published in 1886 under the publishing house C. G. Naumann of Leipzig at the
author's own expense and first translated into English by Helen Zimmern, who
was two years younger than Nietzsche and knew the author.
According to translator Walter Kaufman, the title refers to the need for moral
philosophy to go beyond simplistic black and white moralizing, as contained in
statements such as "X is good" or "X is evil".
