“To feel envy is human, to savour schadenfreude is devilish.”

“Politeness is to human nature what warmth is to wax. ”

“The two enemies of human happiness are pain and boredom.”

“How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.”

“Thus the will to live everywhere preys upon itself, and in different forms is its own nourishment, till finally the human race, because it subdues all the others, regards nature as a manufactory for its own use. Yet even the human race...reveals in itself with most terrible distinctness this conflict, this variance of the will with itself; and we find homo homini lupus.”

“Human life must be some kind of mistake. The truth of this will be sufficiently obvious if we only remember that man is a compound of needs and necessities hard to satisfy; and that even when they are satisfied, all he obtains is a state of painlessness, where nothing remains to him but abandonment to boredom. This is direct proof that existence has noreal value in itself; for what is boredom but the feeling of the emptiness of life? If life—the craving for which is the very essence of our being—were possessed of any positive intrinsic value, there would be no such thing as boredom at all: mere existence would satisfy us in itself, and we should want for nothing.”

“Money is human happiness in the abstract; and so the man who is no longer capable of enjoying such happiness in the concrete, sets his whole heart on money.”
