Courage (n.) doubles with witnesses: one is twice as glad to leap after a drowning man when others present dare not.
Courage (n.) in the ordinary man comes from not seeing the danger — and the hero's only vulnerable spot is his back, where he has no eyes.
Courage (n.) is the best slayer: it slays dizziness at the abyss, slays pity, and even slays death, saying "Was that life? Well then! One more time!"
Courage (n.) is not courage before witnesses but that of hermits and eagles, which not even a god looks at anymore: seeing the abyss with pride.
Courage (n.) is humanity's whole prehistory, not fear: man robbed the wildest animals of their virtues, and courage refined with eagle's wings and snake's cleverness is called Zarathustra.
Courage (n.) of a believer can never be courage without witnesses — this alone degrades it; and moral courage is courage rooted in fear of fear.
Courage (n.) from despair makes a principle of what one lacks — as Wagner, lacking nature and training, invented "dramatic music," the music he was capable of.
Courage (n.) falls short even in the most courageous of us before what he really knows — where a man halts and says 'here is the truth' is decided by his valour more than by his eye.
