Is Happiness Just Math? Utilitarianism Explained

In the entrance of University College London sits a glass case containing the preserved skeleton of Jeremy Bentham, dressed in his own clothes, padded with hay, topped with a wax head. He requested it in his will. He called it an auto-icon and argued the dead should make themselves useful — even his corpse was supposed to produce a net benefit. That instinct to measure, weigh, and optimize is the engine of everything he built. Bentham's principle: the right action is the one that produces the greatest happiness for the greatest number, where happiness means pleasure minus pain. Everyone counts equally — a king's suffering weighs no more than a beggar's. He used this logic to argue for abolishing slavery, ending capital punishment, and extending legal protections to animals. But the same calculus produced the panopticon — a prison where one watchman sees every inmate. His student John Stuart Mill thought Bentham missed something: some pleasures are higher than others. "It is better to be Socrates dissatisfied than a fool satisfied." Bernard Williams pushed further: imagine you must shoot one prisoner to save nineteen. The math is obvious. But the person who pulls the trigger is not the same person who did the calculation. 🎓 Part of Courant Philosophiques — Week 13 of 26. ▶️ New episodes every Wednesday. 📖 Further Reading: Bentham, An Introduction to the Principles of Morals and Legislation Mill, Utilitarianism Peter Singer, Practical Ethics Stanford Encyclopedia of Philosophy: https://plato.stanford.edu/entries/utilitarianism-history/ #philosophy #utilitarianism #bentham #jsmill #trolleyproblem #theparlor
