Bentham tried to turn morality into arithmetic

Jeremy Bentham proposed that any action's rightness could in principle be calculated by weighing the pleasure and pain it causes across seven dimensions — intensity, duration, certainty and more — then summing the result for everyone affected. His 'felicific calculus' underpins utilitarianism: the idea that the right action produces the greatest happiness for the greatest number.
