Context

“practically it becomes cynical renunciation, which prefers once for all to reject all means of relief and all alleviations—it reduces us to the position of dogs, like Diogenes in his tub. The truth is, we ought to be wretched, and we are so. The chief source of the serious evils which affect men is man himself: homo homini lupus. Whoever keeps this last fact clearly in view beholds the world as a hell, which surpasses that of Dante in this respect, that one man must be the devil of another. For this, one is certainly more fitted than another;” source
