Arthur Schopenhauer — "The world is a place where we are all condemned to suffer."

"The only way to escape the suffering of life is to kill oneself."

"There is no absurdity so palpable but that it may be firmly planted in the human head if you only begin to inculcate it before the age of five, by constantly repeating it with an air of great solemnit…"

"It is a wise thing to be polite; consequently, it is a stupid thing to be rude. To make enemies by unnecessary and willful incivility, is just as insane a proceeding as to set your house on fire."

"The more a man has in himself, the less he will want from others."

"Human life must be some kind of mistake."
