Utilitarianism: Maximizing Good and Its Paradoxes

The Principle of Utility

Jeremy Bentham (1748–1832) and John Stuart Mill (1806–1873) created utilitarianism—the most influential ethical theory in the Anglo-Saxon world. Its central principle: the right action is that which produces the greatest happiness for the greatest number of people.

Bentham proposed the hedonistic calculus—a quasi-mathematical instrument for measuring pleasures and pains according to their intensity, duration, certainty, propinquity, fecundity, purity, and extent (how many people are affected). Add up all pleasures, subtract all pains—and you get the "moral balance" of an action.

Mill refined the theory: not all pleasures are equal in quality. “It is better to be a dissatisfied Socrates than a satisfied pig.” Higher pleasures (intellectual, moral, aesthetic) surpass lower ones, even at lesser intensity. This makes utilitarianism more in tune with our intuitions.

Act and Rule Utilitarianism

Act utilitarianism: each specific action is evaluated according to its consequences. This is maximally flexible, but creates a problem: sometimes calculation requires actions that seem clearly immoral.

A classic illustration: if executing one innocent person would prevent a riot in which one hundred would die—should you execute? Act utilitarianism says: yes. Most people say: no—and this shows that we have moral intuitions not reduced to the calculation of consequences.

Rule utilitarianism responds to this challenge: what must be maximized is not the exact result of each individual action, but adherence to rules which overall maximize good. The rule “do not execute the innocent” maximizes total good, even if a particular case appears otherwise. This joins rule utilitarianism to deontology.

Paradoxes of Utilitarianism

The problem of distribution: utilitarianism cares about the sum of happiness, not its distribution. A society where a million people are happy at the expense of a thousand suffering slaves may have a high “moral balance.” John Rawls called this a fundamental flaw: utilitarianism fails to respect the distinction between people; it “merges” everyone into one social whole.

The problem of rights: utilitarianism does not recognize rights in the strict sense. Any right may be violated if it maximizes good. Yet rights make sense precisely when they protect against the “tyranny of the majority”—when the majority wants to infringe on a minority for its own pleasure.

The problem of measurement: how can we measure and compare the happiness of different people? How to compare the happiness from music to that from food? Utilitarian calculation presupposes what is practically impossible—precise interpersonal comparison of utility.

Utilitarianism in Politics and Economics

Despite criticism, utilitarianism remains the basic philosophy behind cost-benefit analysis, regulatory policy, and welfare economics. When a regulator decides whether to introduce a new safety standard, they weigh the costs (who pays and how much) against the benefits (how many lives are saved). This is a utilitarian logic.

Peter Singer applied utilitarianism to global ethics: if you can save a life by donating a small sum—you are obliged to do so. The distance between you and the suffering person is of no moral significance. This leads to radical conclusions about our obligations to the poor in the world—and to lively debate about the limits of moral requirements.
