Someone shared this quote with me, saying it's from Nietzsche, but I can't find a source for the translation:
Is it not the case that all human institutions are intended to prevent mankind from feeling their life, by means of constant dispersion of their thoughts?
I think it might be from page 235 of an English translation of Hadot's Philosophy as a Way of Life.
If that's the case, then it was translated from German to French and then to English, so it's rather indirect.
