“He who fights with monsters might take care lest he thereby become a monster. And if you gaze for long into an abyss, the abyss gazes also into you.” – Nietzsche (Beyond Good and Evil: Prelude to a Philosophy of the Future (1886), Chapter IV. Apophthegms and Interludes, §146).
I’ve been reading a little Nietzsche and I find his philosophy fascinating so far, but I’m having trouble understanding this quote. My own take is that, evil can corrupt you if you are in an environment amongst it, and aren’t careful and vigilant against its tempting nature? Can someone enlighten me on what Nietsche really means by this quote?
