“Warning to the despised. – If you have unmistakably sunk in the estimation of men you should hold on like grim death to decorum in society with others: otherwise you will betray to them that you have sunk in your own estimation too. When a man is cynical in society it is a sign that he treats himself like a dog when he is alone.”

“He who fights with monsters should look to it that he himself does not become a monster . . . when you gaze long into the abyss the abyss also gazes into you”

“Can you give yourself your own evil and your own good and hang your own will over yourself as a law? Can you be your own judge and avenger of your law? Terrible it is to be alone with the judge and avenger of one's own law. Thus is a star thrown out into the void and into the icy breath of solitude. Today you are still suffering from the many being one: today your courage and your hopes are still whole. But the time will come when solitude will make you weary, when your pride will double up and your courage gnash its teeth. And you will cry, "I am alone!" The time will come when that which seems high to you will no longer be in sight, and that which seems low will be all-too-near; even what seems sublime to you will frighten you like a ghost And you will cry, "All is false!”

“The person who fights monsters should make sure that in the process, he does not become a monster himself. Because when you stare down at an abyss, the abyss stares back at you.”

“Man permits himself to be lied to at night, his life long, when he dreams, and his moral sense never even tries to prevent this—although men have been said to have overcome snoring by sheer will power.”

“We no longer have a sufficiently high estimate of ourselves when we communicate. Our true experiences are not garrulous. They could not communicate themselves if they wanted to: they lack words. We have already grown beyond whatever we have words for. In all talking there lies a grain of contempt. Speech, it seems, was devised only for the average medium, communicable. The speaker has already vulgarized himself by speaking.”

“He who despises himself esteems himself as a self-despiser.”
