Not necessity, not desire - no, the love of power is the demon of men. Let them have everything - health, food, a place to live, entertainment - they are and remain unhappy and low-spirited: for the demon waits and waits and will be satisfied.
You needn't tell me that a man who doesn't love oysters and asparagus and good wines has got a soul, or a stomach either. He's simply got the instinct for being unhappy highly developed.
