“The truth is that we ought to be wretched and are so. The chief source of the most serious evils affecting man is man himself, homo homini lupus: Man is wolf for man. He who keeps this last fact clearly in view beholds the world as a hell, surpassing that of Dante by the fact that one man must be the devil of another.”

– Arthur Schopenhauer, On the Vanity and Suffering of Life
