Long time follower, first time asker
I deeply identify with the second part Nietzsche's aphorism:
'He who fights with monsters should look to it that he himself does not become a monster. And if you gaze long into an abyss, the abyss also gazes into you.'
(Wer mit Ungeheuern kämpft, mag zusehn, dass er nicht dabei zum Ungeheuer wird. Und wenn du lange in einen Abgrund blickst, blickt der Abgrund auch in dich hinein.)
As it relates to a thirst for knowledge that takes you deeper into the rabbit hole (one -- potentially wrong -- interpretation). I found that sometimes unanswerable questions have obsessed me past the point of healthy living, and that to get out of this mindset I had to... just stop gazing
However I do not think this was a novel idea. Are there any examples of this idea in ancient philosophy? Citations & references appreciated
