Mill's Utilitarianism › The Intellectual Inheritance

Mill didn't invent utilitarianism. That credit belongs to Jeremy Bentham, the eccentric philosopher who called for calculating pleasure and pain with quasi-mathematical precision. Bentham's _felicific calculus_ weighed the intensity, duration, certainty, and extent of pleasures to determine the right action. His motto was unambiguous: "The greatest good for the greatest number." Bentham's version had problems. Critics mocked it as a "philosophy fit for pigs." If pleasure is all that matters, shouldn't we wire everyone to dopamine drips? Thomas Carlyle called it "pig philosophy," suggesting it reduced humans to sensation-seeking animals. Mill, Bentham's godson and intellectual heir, inherited both the doctrine and its reputation problem. Raised from childhood as the perfect utilitarian (learning Greek at three, reading Plato in the original at seven), he suffered a devastating mental breakdown at twenty. The crisis forced him to question whether a life organized entirely around rational calculation could sustain human happiness. *Utilitarianism* represents Mill's mature attempt to rehabilitate the theory, answering critics while refining its core claims. What emerges is both a robust philosophical system and a surprisingly nuanced guide to ethical life.
