He who fights against monsters should see to it that he does not become a monster in the process. And when you stare persistently into an abyss, the abyss also stares into you.
— Friedrich Nietzsche

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.
Friedrich Nietzsche monster quote

Never allow a monster to reach into the mind or heart, and silence a free soul, with fear and threat of liberty lost.
— Bryant H. McGill

I have never seen a greater monster or miracle than myself.
— Michel de Montaigne

Whoever battles with monsters had better see that it does not turn him into a monster. And if you gaze long into an abyss, the abyss will gaze back into you.
— Friedrich Nietzsche
