“Whoever does not believe himself always lies.”

“Today as always, men fall into two groups: slaves and free men. Whoever does not have two-thirds of his day for himself, is a slave, whatever he may be: a statesman, a businessman, an official, or a scholar.”

“Whoever extolls him as a God of love, does not think highly enough of love itself.”

“The visionary lies to himself, the liar only to others.”

“He who does not lie does not know what truth is.”

“Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you.”

“He who obeys, does not listen to himself!”
