Utilitarianism

This is Unit Four of Ethics and Values: Utilitarianism. The theories so far have mostly told you where morality comes from. This one tells you what to do. It gives a single test, applies it to any action, and returns a verdict. The test is about outcomes. Whether an act is right depends on how much happiness it produces for everyone it touches, with each person's happiness counting the same as anyone else's. That clarity is why the theory has been taken seriously for two centuries, and the objections are serious in the same way. Most of them work by finding a case where the sums come out one way and almost everyone's judgment comes out the other. By the end you will be able to do five things. One: state the principle of utility, and say what hedonism makes it measure. Two: state the swine objection, and Mill's reply about the quality of pleasures. Three: tell act utilitarianism from rule utilitarianism, and state the problem that the move to rules runs into. Four: name the five standard objections, and say what each one targets. Five: run a utility audit on a proposal.

The theory begins with a restriction. Nothing about an action matters to its rightness except what the action brings about — not the intention behind it, not the kind of act it is. Everything else in the unit follows from taking that seriously.

The commitment, stated.

Ethics 151 Consequentialism

Two drivers run the same light; one sails through and one hits a cyclist. On this view that difference is not part of the story — it is the story.

Built on it, the principle itself.

Ethics 152 The Principle of Utility

A council choosing between a clinic and a stadium counts every resident's gain and loss and builds whichever sums higher. The principle is that literal.

If happiness settles rightness, then everything depends on what happiness is taken to be. The classical answer is narrow and precise, it has an ancient root that is usually misremembered, and it comes with an arithmetic and a rule of equality that does more work than it looks like it does.

The measure, in its classical form.

Ethics 153 Hedonism About Happiness

A promotion registers through the satisfaction it brings and the worry it ends. The title itself weighs nothing on this scale.

Its root is older, and quieter.

Ethics 154 Epicurus: The Ancient Root

The caricature is banquets. The letter prescribes bread, water, friends, and an untroubled mind — freedom from pain in body and turmoil in soul.

Bentham turns it into arithmetic.

Ethics 155 Bentham's Calculus

Intensity, duration, certainty, extent. Score a factory rule by the workers affected, the hours of relief, the odds it works — then subtract the costs the same way.

And one rule governs the counting.

Ethics 156 Everybody Counts for One

The mayor's headache and the janitor's headache enter the sum at the same weight. Rank buys nothing at this counter.

The first serious attack goes at the measure rather than the arithmetic. If pleasure is all that counts, the objection runs, the theory has set a standard fit for animals. Mill's answer is the most famous sentence in the tradition, and there is a neighbouring standard worth having beside it.

The attack.

Ethics 157 The Swine Objection

Offer an editor drugged contentment in place of difficult, meaningful work. She refuses, nearly everyone refuses, and pleasure alone was never doing the measuring.

Mill's answer.

Ethics 158 Mill's Quality Reply

Better a human being dissatisfied than a pig satisfied. Those acquainted with both sides choose the harder pleasures, and Mill takes their verdict to settle the ranking.

A different standard, nearby.

Ethics 159 Smith's Impartial Spectator

Before answering the insulting email, imagine an informed, impartial observer reading the exchange. What that observer could go along with is the whole measure.

One principle, two ways of using it. The difference looks technical and turns out to decide how the theory answers almost every objection ahead.

The first applies it act by act.

Ethics 163 Act Utilitarianism

Facing one lie that would spare a town panic, this version scores that lie, in that place, on that day. No rulebook is consulted.

The second applies it to rules.

Ethics 164 Rule Utilitarianism

A hospital forbids lying to patients even where one lie looks merciful, because the practice of truth-telling, kept whole, is what does the most good.

A practical objection arrives before the moral ones. If rightness depends on outcomes, and outcomes run past every horizon, nobody can grade an action — before or after. The reply is what makes the theory usable.

The problem.

Ethics 165 The Ignorance Objection

A rescued swimmer may turn out to be anyone at all. If rightness waited on complete foresight, no act could ever be graded by anyone.

The repair.

Ethics 166 The Expected-Utility Reply

Medicine already works this way. A treatment is right on the evidence in hand, and a freak reaction does not convict the careful doctor.

Now the serious objections. Each finds a case where maximising happiness returns a verdict almost nobody accepts — and each targets something different. One is about justice, one about rights, and one about a kind of reason the theory cannot see at all.

The first is about punishing the innocent.

Ethics 171 The Justice Objection

A sheriff can stop five riot deaths by hanging a man he knows is innocent. The sums say hang, and justice says the sums have missed something.

The second is about rights.

Ethics 172 The Rights Objection

If secretly streaming one tenant's flat delights a million viewers, the arithmetic favours the feed. Her claim was meant to be the kind of thing arithmetic cannot touch.

The third is about the direction the theory faces.

Ethics 173 The Backward-Looking-Reasons Objection

You promised a friend, now dead, to tend the garden. Utility finds better uses for the hour, and the promise still pulls — from the past, where a forward-facing theory cannot look.

Two more objections, both about what living by the theory would actually involve. One says it leaves no room for a life. The other says it leaves no room for the people in yours.

The first is about how much it demands.

Ethics 174 The Too-Demanding Objection

Every pound of the architect's salary could fight famine. Taken strictly, her concert ticket is a moral failure, and so is the next one.

The second is about who you may favour.

Ethics 175 The Partiality Objection

Two children need the last dose and one is yours. Counting everyone for one says flip a coin, and almost no parent believes the coin is morality.

Utilitarians answer in three ways, and they are genuinely different strategies — dispute the case, accept the verdict, or change the theory. The third is the most popular, and it runs into a difficulty that has never quite been settled.

The first disputes the case.

Ethics 176 First Defense: The Cases Are Rigged

Price the sheriff's scapegoat properly: discovery, ruined trust in courts, emboldened mobs. Done honestly, the defence says, the arithmetic votes with justice.

The second accepts the verdict.

Ethics 177 Second Defense: Revise Common Sense

Settled intuition once defended slavery and denied women the vote. A theory that shocks common sense is sometimes correcting it rather than failing.

The third changes the theory.

Ethics 178 Third Defense: Move to Rules

The sheriff consults practices rather than cases, and a justice system that hangs scapegoats collapses trust wholesale. The rule fails the audit, so the act is out.

And here is what that move costs.

Ethics 179 The Collapse Problem

If this one merciful lie truly does the most good, why keep the rule? Allowing the break turns the theory into the act version; forbidding it serves the rule instead of happiness.

The theory turned into something you can actually run. Four steps, and the one that decides the outcome is the first — because a verdict is only as honest as the list of people it counted.

Watch the audit run on a real proposal.

Ethics 185 Running a Utility Audit

List the affected, estimate each gain and loss, sum with everyone counting once, then re-check at the level of rules. An audit is only as honest as its list of the affected.

The unit closes on the case that made a generation of philosophers uncomfortable. Five patients are dying, each needing a different organ, and one healthy visitor could supply all five. Run the tools you now have, and watch what the case does to the theory.

The capstone. Every tool in the unit applies.

Ethics 191 The Transplant Surgeon

The raw sum says take the organs — everyone counted for one, and five exceeds one. The verdict is monstrous, and that is the point of the case rather than a flaw in the telling.

Five things you can now do. You can state the principle of utility — an act is right in proportion as it promotes happiness for everyone affected — and say what hedonism makes that measure: pleasure, and the absence of pain. You can state the swine objection and Mill's reply: pleasures differ in quality, and the verdict of those acquainted with both sides settles the ranking. You can tell act utilitarianism from rule utilitarianism, and state the collapse problem — allow the profitable break and the rule version becomes the act version; forbid it and the rules are being served instead of happiness. You can name the five objections and what each targets: justice, rights, reasons from the past, how much the theory demands, and whom you are allowed to favour. And you can run a utility audit, beginning where it has to begin — with an honest list of everyone affected.
