Jeremy Bentham · Philosophy
Bentham’s founding idea: that pleasure and pain are the only real goods and evils, and that the one rational test of any action or law is whether it tends to increase or diminish happiness - <em>the greatest happiness of the greatest number</em>.
Jeremy Bentham opened his great work of 1789 with one of the most famous sentences in moral philosophy, and built an entire system on it. Human beings, he observed, are governed by two forces and two only: the pursuit of pleasure and the avoidance of pain. These are not just what move us; they are what ought to guide us, for there is nothing else that could count as good or bad except the pleasure and pain of sentient beings. From this Bentham drew his ‘principle of utility’: the rightness of any action is measured by its tendency to produce happiness (pleasure) or to prevent it (pain). Everything else that has ever been offered as the foundation of morals - divine command, natural law, moral sense, the fitness of things - is, for Bentham, either a confused way of pointing at utility or a mask for personal prejudice. Morality is not a mystery to be intuited; it is a question about consequences, and consequences can, in principle, be reckoned.
Bentham had announced his master-idea years earlier, in A Fragment on Government (1776), where he called it the ‘fundamental axiom’ of his thought: that it is the greatest happiness of the greatest number that is the measure of right and wrong. The phrase captures two commitments at once. First, happiness is the goal - not glory, not piety, not the majesty of the state, but the actual well-being of actual people. Second, whose happiness counts is settled impartially: not the king’s, not the aristocrat’s, not any privileged class’s, but everyone’s, added up. This was a radical, levelling doctrine in an age of inherited privilege. It made the humblest labourer’s pleasure and pain weigh in the moral scales exactly as much as a duke’s, and it turned the whole business of government into a single practical task: to arrange laws and institutions so that they produce the largest possible balance of happiness over misery across the whole community.
The principle of utility, Bentham insisted, is not merely a rule for personal virtue; it is the standard for legislation, which was always his deepest concern. He defined it with care: the principle of utility approves or disapproves of every action whatsoever according to its tendency to augment or diminish the happiness of the party whose interest is in question - and this applies, he stressed, ‘not only to every action of a private individual, but of every measure of government.’ A law is a device for producing happiness, and it should be judged by nothing else. This gave Bentham a lever to move the whole apparatus of the state. Every statute, every punishment, every institution could now be interrogated: does it actually add to the sum of human well-being, or does it merely persist out of habit, superstition, or the interest of the powerful few? Utility became the reformer’s measuring-rod, and Bentham spent his life applying it to prisons, courts, poor laws, and constitutions.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Bentham grounded morality in a single measurable standard: an action is right insofar as it tends to augment the happiness of everyone whose interest is at stake, and that this ‘greatest happiness principle’ applies equally to private conduct and to legislation. Explain the principle and why Bentham t…
