“The man who grounds his action on another's cowardice, is essentially a coward himself.”

“The suffering may be moral or physical; and in my opinion it is just as absurd to call a man a coward who destroys himself, as to call a man a coward who dies of a malignant fever.”

“I am a coward. I am a cowardly coward, full of cowardice.”

“Your weak side, my diabolic friend, is that you have always been a gull: you take Man at his own valuation. Nothing would flatter him more than your opinion of him. He loves to think of himself as bold and bad. He is neither one nor the other: he is only a coward. Call him tyrant, murderer, pirate, bully; and he will adore you, and swagger about with the consciousness of having the blood of the old sea kings in his veins. Call him liar and thief; and he will only take an action against you for libel. But call him coward; and he will go mad with rage: he will face death to outface that stinging truth. Man gives every reason for his conduct save one, every excuse for his crimes save one, every plea for his safety save one: and that one is his cowardice. Yet all his civilization is founded on his cowardice, on his abject tameness, which he calls his respectability. There are limits to what a mule or an ass will stand; but Man will suffer himself to be degraded until his vileness becomes so loathsome to his oppressors that they themselves are forced to reform it.”

“Nothing wrong with cowardice as long as it comes with prudence. But when a coward stops remembering who he is... God help him.”

“His malice was aimed at himself; with shame and contempt he recollected his "cowardice.”
