“Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people's hats off--then, I account it high time to get to sea as soon as I can. This is my substitute for pistol and ball. With a philosophical flourish Cato throws himself upon his sword; I quietly take to the ship.”
― Herman Melville, Moby Dick

“So when you find yourself locked onto an unpleasant train of thought, heading for the places in your past where the screaming is unbearable, remember there's always madness. Madness is the emergency exit.”
― Alan Moore, Batman: The Killing Joke

“The thoughts written on the walls of madhouses by their inmates might be worth publicizing.”
― Georg Christoph Lichtenberg

“A great many men are mad, and no one knows it. They do not know it themselves”
― Agatha Christie, The Secret Adversary
