One of the most destructive anti-concepts in the history of moral philosophy is the term 'duty.
Ayn RandGod help us, ma'am! Do you see what we saw? We saw that we'd been given a law to live by, a moral law, they called it, which punished those who observed it - for observing it. The more you tried to live up to it, the more you suffered; the more you cheated it, the bigger reward you got. Your honesty was like a tool left at the mercy of the next man's dishonesty. The honest ones paid, the dishonest collected. The honest lost, the dishonest won. How long could men stay good under this sort of a law of goodness?
Ayn RandPsychologically, the choice "to think or not" is the choice "to focus or not." Existentially, the choice "to focus or not" is the choice "to be conscious or not." Metaphysically, the choice "to be conscious or not" is the choice of life or death.
