There are fewer good flutes than flute players. Who gets the best one?

The richest player? The best-born? The one who'd enjoy it most? The one who was taught least and needs it most? Or whoever bought it fair and square? Aristotle's answer, in the Politics (Book III), was blunt: give the best flute to the best flute player, "for he will play never the better" for being well born. Every theory of justice since has been, in a sense, an argument about flutes.

The Veil of Ignorance introduced John Rawls's thought experiment and his two principles, and sketched the utilitarian and libertarian objections in a paragraph each. This deep dive gives each of the big traditions its full case, from Plato's Republic to the economists and philosophers still arguing today. It doesn't pick a winner. Justice is the subject where reasonable people disagree most, and the most useful thing you can take away is a clear view of what they disagree about.

Part 1 — Plato: justice as a well-ordered soul and city

The Republic opens with a challenge that has never quite been answered. In Book I, the hot-tempered sophist Thrasymachus breaks into a polite conversation:

"I proclaim that justice is nothing else than the interest of the stronger." — Thrasymachus, in Plato's Republic, Book I (tr. Benjamin Jowett)

Laws are written by those in power to serve themselves, he says, and "justice" is just the name the weak are taught to give to obedience. In Book II, Plato's brother Glaucon sharpens it with a story. A shepherd named Gyges finds a ring that makes him invisible. Within a short time he has seduced the queen, killed the king and taken the kingdom. Give the ring to a just man and an unjust one, Glaucon says, and "no man can be imagined to be of such an iron nature that he would stand fast in justice." If people are only just because they fear getting caught, then justice is a deal we put up with, not something good in itself.

Socrates spends the rest of the book replying. His strategy is to look at justice "writ large," in an ideal city, and then read it back into the individual. The city has three classes:

Justice is the condition in which each part does its own work and doesn't meddle in the others' (Book IV). In a person, that means reason rules, spirit backs it up, and appetite is kept in proportion. Injustice is a kind of civil war in the soul. So the answer to Gyges is that the ring wouldn't make you happier. A person ruled by appetite and ambition is disordered and miserable inside, however much he gets away with.

Then comes the famous demand. Cities, Socrates says, "will never have rest from their evils" until "philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy" (473). The guardians live without private property or private families. To keep the classes stable, Socrates even proposes a "royal lie," a myth that the god mixed gold into rulers, silver into soldiers and iron and bronze into workers.

The strongest case for Plato is that he refuses to treat justice as only a matter of rules or shares. A society is just when it's well ordered, when each person contributes what they're best at and the whole is governed by wisdom rather than greed. That idea lives on wherever people argue that justice requires good character, not just good procedures.

The strongest case against was made most famously by Karl Popper in The Open Society and Its Enemies (1945), who charged that the Republic is a blueprint for totalitarianism: rule by an unaccountable elite, a city whose unity matters more than its citizens, and a lie at its foundation. Scholars still disagree about how fair that charge is. Some argue Plato's rulers aim at the good of every citizen; others answer that the Republic's idea of a "maximally unified" city can't be reduced to individual good. Either way, notice what's missing from Plato's justice: equality, consent and rights. Those arrive much later.

Plato's question outlived his answer: is justice good in itself, or just the price we pay for safety?

Part 2 — Aristotle: to each according to merit, but which merit?

Aristotle brought justice down to earth. In Book V of the Nicomachean Ethics he splits it into two kinds.

• Corrective justice applies to dealings between people: contracts, theft, injury. Here everyone is treated as equal. If you take something from me, the judge restores the balance, whoever we are.
• Distributive justice applies when a community shares out something common: offices, honors, money. Here equal treatment means proportional treatment. Equals should get equal shares, and unequals unequal ones.

He's sharp about why this is so hard:

"This is the very source of all the quarrelling and wrangling in the world, when either they who are equal have and get awarded to them things not equal, or being not equal those things which are equal." — Nicomachean Ethics V.3 (tr. D. P. Chase)

Everyone agrees, Aristotle says, that distributions should follow some kind of worth. They disagree about what counts: "the democrats are for freedom, oligarchs for wealth, others for nobleness of birth, and the aristocratic party for virtue." That sentence is still a good diagnosis of political arguments. Most fights about fairness are really fights about which kind of merit should count.

His own answer is teleological. To decide who deserves something, ask what it's for. Flutes exist to be played well, so the best flutes go to the best players (Politics III.12). Political office exists to promote the good life of the city, so it should go to those with the civic virtue to promote it. Height, beauty and family don't count, because they have nothing to do with "the business in hand."

The strongest case for Aristotle: it matches how we actually reason about many goods. University places, medical residencies and Olympic squads are handed out by asking what the good is for. It's also the root of a long line of thought about justice and the good life that Michael Sandel revives (Part 7).

The strongest case against: deciding what a thing is "for" can smuggle in a whole view of life that others don't share. And Aristotle's own conclusions are a warning. The same Politics argues that some people are "slaves by nature" and gives women a lesser place in the household. A theory that hands out goods by worth is only as fair as its judgment of who is worthy.

Part 3 — The utilitarians: justice as the most important kind of usefulness

For Jeremy Bentham and John Stuart Mill, justice isn't a separate value. It's part of utility, the promotion of happiness and the reduction of suffering. Bentham's motto, as Mill reports it, is the egalitarian heart of the view: "everybody to count for one, nobody for more than one."

Mill's Utilitarianism (1861) devotes its last chapter to the obvious objection: doesn't justice often conflict with the greatest good? His answer is that justice is the name for the most important utilitarian rules, the ones protecting security, which we need more than anything else:

"Justice is a name for certain classes of moral rules, which concern the essentials of human well-being more nearly, and are therefore of more absolute obligation, than any other rules for the guidance of life." — Mill, Utilitarianism, ch. 5

That's why, Mill argues, justice feels different from ordinary usefulness, sterner and more like a right. Rights are just utility's most heavily guarded rules.

Utilitarianism also has a built-in argument for redistribution. An extra $1,000 means far more to someone earning $15,000 a year than to someone earning $1.5 million. Economists call this diminishing marginal utility. If happiness is what matters, moving money from the rich to the poor will usually raise the total, up to the point where taxes start shrinking the pie.

The strongest case for utilitarian justice: it's impartial and focused on real lives. It asks what actually happens to people, and it counts everyone equally.

The two strongest objections:

1. It ignores the "distinctness of persons." This is Rawls's famous charge, often called the separateness of persons. One person may sensibly accept pain now for a better life overall. But society isn't one person. Utilitarianism applies that same logic across different people, and so in principle it can let some be sacrificed if the gains to others are large enough. That's the trolley problem's surgeon, written into policy.
2. No one can do the arithmetic. To compare policies you'd need to know how every option affects every person's welfare, and you'd have to settle disputes about how fast utility diminishes. Different, equally reasonable assumptions give opposite answers. Utilitarians reply that rough estimates guide most real decisions well enough.

Part 4 — Rawls beyond the veil: the principles in full

The Veil of Ignorance covered the original position and maximin. Here is what the theory looks like up close. Rawls's settled version of his two principles (from Political Liberalism, 1993, and Justice as Fairness: A Restatement, 2001) runs, in paraphrase:

1. Equal basic liberties. Each person has an equal claim to a fully adequate scheme of basic rights and liberties (speech, conscience, association, the vote, the integrity of the person), compatible with the same for all. The political liberties must have their fair value: similar chances to influence politics whatever your wealth.
2. Social and economic inequalities must meet two conditions:
   - (a) Fair equality of opportunity. Positions are open to all, and people with the same talent and willingness to use it have the same prospects, whether born rich or poor.
   - (b) The difference principle. Inequalities must be "to the greatest benefit of the least advantaged members of society."

The principles are ranked. The first has lexical priority over the second, and (a) over (b). You can't trade away anyone's basic liberties for economic growth, even growth that would help the worst off.

Three features are often missed.

The subject is the "basic structure." Rawls isn't telling you how to split a restaurant bill. His principles apply to the major institutions (constitution, property law, tax system, markets, the family) that shape people's prospects from birth. That's why the theory is about institutions, not individual acts.

What gets measured: "primary goods." Rawls compares people's positions by things every citizen needs whatever their plan of life: basic rights and liberties, freedom of movement and occupation, powers of office, income and wealth, and the "social bases of self-respect."

The difference principle is about the worst off's absolute position, not inequality as such. Here's an illustration, with three equal-sized groups and incomes in thousands per year:

Rawls prefers C to A even though C is unequal, because the worst off have more. He rejects D even though it's richer on average, because the gains at the top come partly at the expense of the bottom. The underlying idea is that nobody deserves their natural talents or the family they were born into. Citizens treat the distribution of talents as "a common asset" whose rewards should benefit everyone. In Rawls's phrase, in justice as fairness people "agree to share one another's fate."

Why maximin? The main critic. The economist John Harsanyi argued that rational people behind a veil should assume an equal chance of being anyone and maximize average utility, which picks D. Rawls replied that the original position is a one-off choice with no second chances, where some outcomes are intolerable. It's rational to choose cautiously there, he argued, much as it's rational to insure your house even if you love risk.

What kind of society? People often assume Rawls was defending the modern welfare state. He wasn't. In the Restatement he rejects welfare-state capitalism, because it leaves economic and political power with a wealthy few and tends to create a demoralized underclass. He also rejects laissez-faire capitalism and a socialist command economy. He favors either a property-owning democracy, which spreads ownership of productive assets and education widely, or liberal socialism, with worker-managed firms.

The later Rawls. Political Liberalism (1993) responded to a worry his first book raised: a free society will always contain many religions and philosophies. Rawls's answer was that justice as fairness should be a political conception that people of different worldviews can each endorse for their own reasons, an overlapping consensus, rather than one more comprehensive philosophy competing with the rest.

Rawls's question for every inequality: compared with what, and good for whom at the bottom?

Part 5 — Nozick: justice as a clean history

Three years after A Theory of Justice, Rawls's Harvard colleague Robert Nozick published Anarchy, State, and Utopia (1974). Its first line set the tone: "Individuals have rights, and there are things no person or group may do to them (without violating their rights)."

Nozick's entitlement theory says a distribution is just if it came about in the right way. It has three parts:

1. Justice in acquisition: how unowned things can first become someone's property.
2. Justice in transfer: how property can pass from one person to another (sale, gift, exchange, inheritance).
3. Justice in rectification: how to fix violations of the first two.

If everyone's holdings arose through just acquisition and just transfer, the result is just, whatever it looks like. Nozick calls theories like Rawls's patterned or end-state theories: they judge a distribution by its shape (equal, maximin, proportional to effort). His is historical: it judges by how things came about.

Look back at the table in Part 4. Nozick's point is that you can't tell which society is just from those numbers. Suppose society D arose from slavery, and A from a free economy. Then the matrix leaves out everything that matters morally.

The Wilt Chamberlain argument. Nozick asks you to start with whatever distribution you think is just. Call it D1. Now suppose the basketball star Wilt Chamberlain signs a contract under which each fan puts 25 cents in a box for him at every home game. Over a season a million fans do so happily. Chamberlain ends up with $250,000, far more than anyone else, and the pattern is broken. Call the new situation D2.

Is D2 unjust? Everyone started with what was justly theirs. Each fan chose freely what to do with a quarter. Those who didn't want to pay kept their money. Nozick asks:

"If the people were entitled to dispose of the resources to which they were entitled (under D1), didn't this include their being entitled to give it to, or exchange it with Wilt Chamberlain?" — Nozick, Anarchy, State, and Utopia, p. 161

His conclusion is that liberty upsets patterns. Keeping any pattern in place would require constant interference with people's free choices. A socialist society, he wrote, "would have to forbid capitalist acts between consenting adults." He went further: taxing earnings to fund redistribution is "on a par with forced labor," because it takes a portion of your working hours for others' purposes.

The Lockean proviso. Nozick borrowed a limit from John Locke: an acquisition is unjust if it leaves others worse off than they would have been had the thing stayed unowned. He thought this condition was easily met in a free market.

The strongest case for Nozick: it takes seriously something patterned theories can seem to ignore, which is that goods don't fall from the sky. People make them and trade them, and they have plans and claims of their own. It explains the strong intuition that taking what someone earned honestly needs a justification, and it treats each person as more than a means to a good distribution.

The strongest objections and replies:

• "What grounds the rights?" Thomas Nagel's 1975 review, "Libertarianism without Foundations," pressed the point that Nozick asserts strong property rights without arguing for them. Nozick admitted the book offered no "precise theory of the moral basis of individual rights."
• "The Wilt argument misdescribes patterned theories." This is Rawls's own reply. Justice as fairness doesn't redo the pattern after every transaction. It sets up a basic structure (tax rules, regulations, transfers) in advance, so "there are no unannounced and unpredictable interferences" (Political Liberalism, p. 283). Chamberlain was never entitled to his gross pay, only to what he earns under known, fair rules. Nozick's defenders answer that Rawls himself admits "adjustments in the basic structure are always necessary," so unpredictable interference returns by another route. The exchange is still going.
• "Patterns protect liberty too." G. A. Cohen's paper "Robert Nozick and Wilt Chamberlain: How Patterns Preserve Liberty" argued the reverse of Nozick's slogan: the poor have little real freedom, and redistribution can enlarge it.
• "History is dirty." Nozick recognized that the history of almost all real holdings is full of injustice: murder, plunder, enslavement and fraud. Rectifying them could require large transfers. He even allowed that, in the short run, this might justify "a state more extensive than the minimal state." Critics say that admission swallows the theory. Defenders say it shows the theory is honest.

Nozick himself later wrote, in The Examined Life (1989), in terms that seemed to repudiate parts of his earlier view. Later still he played that retreat down. The argument outlived its author's doubts, and it's still the most powerful statement of the case that justice is about how things came about, not how they're shared.

Part 6 — Sen and Nussbaum: what people can actually do and be

In a 1979 lecture titled "Equality of What?", the economist and philosopher Amartya Sen asked a question that cut across Rawls and the utilitarians alike. Every theory of justice, he argued, demands equality of something. The fight is over what.

Sen's answer: neither money nor happiness, but capabilities, the real freedoms people have to achieve functionings, the "doings and beings" they have reason to value: being well nourished, being healthy, moving about, reading, working, appearing in public without shame, taking part in community life.

His key example is two people with exactly the same income. One uses a wheelchair. She's worse off in two ways that a money count misses. She can do less with the same money, because many places aren't accessible. And she has to spend part of that money on the wheelchair just to get around. Resources aren't the same as freedom, because people differ in conversion factors: how much living a person can get out of a given good. A bicycle means mobility to someone who can ride, and much less to someone who can't.

Sen's point in one line: equal resources can mean unequal lives.

Sen was just as critical of utilitarian measures. Suppose the disabled person is a "pleasure wizard," cheerful and easily satisfied. A happiness metric would then direct fewer resources to her, which seems plainly wrong. Worse, Sen documented that people who live in deprivation often lower their expectations as a way of coping. Measuring justice by satisfaction rewards that adjustment instead of addressing the deprivation behind it.

This approach went far beyond philosophy. In 1990 Sen and the economist Mahbub ul Haq developed the Human Development Index for the United Nations Development Programme. It ranks countries by life expectancy, education and income instead of income alone. It has only three dimensions, weighted equally, and Sen was concerned about its crudeness from the start. Mahbub ul Haq won him over with the argument that a single composite number could compete for attention with the equally crude GDP per capita. Sen's work in social choice theory earned him the 1998 Nobel Prize in Economics.

Nussbaum's list. The philosopher Martha Nussbaum, who worked with Sen, built a more definite theory. She argues that a life worthy of human dignity requires a threshold level of ten central capabilities, which every government owes its people:

She frames the list as open to revision and argues it could be the object of a Rawlsian overlapping consensus. Sen refuses to endorse any such list. He has said he won't defend "one pre-determined canonical list of capabilities, chosen by theorists without any general social discussion or public reasoning." For him, each society should choose and weigh capabilities through democratic debate.

Sen against "perfect justice." In The Idea of Justice (2009), dedicated to Rawls's memory, Sen went after the method of the whole tradition. Rawls, he argued, practices transcendental institutionalism: trying to describe the perfectly just society. But we don't need to know what perfect justice looks like in order to see that ending a famine, a form of discrimination or a preventable epidemic would make the world more just. Justice should be comparative, focused on removing clear, fixable injustices through public reasoning.

The strongest case for the capability approach: it looks at what matters in people's actual lives, takes disability and gender seriously, and has changed how the world measures development.

The strongest objections:

• Under-theorized. Without a list, critics say, Sen's approach can't tell a government what it owes or how to trade one capability against another. Nussbaum's list answers that, but at a cost.
• Not neutral. Rawlsians reply that judging people's functionings means judging what a good life is, which a liberal state should avoid. Resources leave each person free to pursue their own idea of the good.
• A false dichotomy. Some critics, such as Biondo (2012), argue that Sen's contrast between "transcendental" and "comparative" justice is misleading. To rank two societies, you need some idea of what you're ranking them toward.

Part 7 — Sandel and the communitarians: justice can't be neutral

In the 1980s a group of philosophers attacked Rawls from a new direction. Alasdair MacIntyre (After Virtue, 1981), Michael Walzer (Spheres of Justice, 1983), Charles Taylor and Michael Sandel came to be called communitarians. None of them chose the label. Others pinned it on them, usually critics, and they disagree among themselves. But they shared a target.

Sandel's Liberalism and the Limits of Justice (1982) went after the self that Rawls's theory seems to assume. Behind the veil, the parties know nothing about their own ends, attachments or communities. They're pure choosers who stand prior to everything they value. Sandel, in a 1984 essay, called this the unencumbered self. Real people, he argued, aren't like that. We ordinarily understand ourselves

"as members of this family or community or nation or people, as bearers of this history, as sons or daughters of that revolution, as citizens of this republic." — Michael Sandel, Liberalism and the Limits of Justice

Some of those attachments are part of who we are, not choices we stand back from. If so, Rawls's priority of the "right" over the "good," the idea that the state should be neutral among ways of life, can't be maintained. You can't decide what's just without asking what's good, what a practice or institution is for. In this sense Sandel is reviving Aristotle's flutes.

The others added their own versions. Taylor's essay "Atomism" defended Aristotle's view that humans are political animals who can't flourish outside a community. Walzer argued that different goods (medical care, office, money, love) have different social meanings and so should be shared out by different principles. Money shouldn't buy what merit or need should decide. MacIntyre argued that moral reasoning only makes sense inside a tradition.

The strongest case for the communitarians: they capture how moral life actually feels. Loyalty, belonging and inherited obligation are real, and politics that ignores them can leave people feeling abandoned. Sandel's later popular books, What Money Can't Buy (on markets reaching into areas where they don't belong) and The Tyranny of Merit (2020), on how meritocracy breeds arrogance among winners and humiliation among losers, carried the argument into public life. His Harvard course "Justice" is free online.

The strongest replies from liberals:

• Rawls adjusted. Political Liberalism recast justice as fairness as a political view, not a theory of the self. The veil is a device of representation, not a picture of human nature. In The Law of Peoples (1999) Rawls even allowed that liberalism might not be exportable everywhere, and that liberal societies must tolerate "decent" non-liberal ones.
• The ability to revise. Liberals reply that the point isn't that we choose all our attachments. It's that we need the freedom to question and revise them, because some inherited ends are harmful. A community's shared values can include oppressive ones, and Walzer himself offered the Indian caste system, "where the social meanings are integrated and hierarchical," as a society that might be just by its own standards. Few readers found that reassuring.
• Whose community? In diverse societies, appeals to "our shared good" raise the question of whose good gets to count.

Other voices. Two more lines of criticism deserve mention. The feminist philosopher Susan Moller Okin (Justice, Gender, and the Family, 1989) documented how the family as usually organized leaves women in a position of systematic material and political inequality, and argued that liberal theories that stay neutral about the "private" sphere can't see it. And the debate over luck egalitarianism, the view (associated with Ronald Dworkin and others) that inequalities are unjust when they come from unchosen luck but fair when they come from people's own choices, drew a sharp reply from Elizabeth Anderson's "What Is the Point of Equality?" (1999). She argued that the point of equality is a society where people stand as equals, not compensation for bad luck, and that the luck view is harsh: it can leave people responsible for their own misery alone with it.

Part 8 — A live debate: one case, five verdicts

Take a single case and run it through every theory. A software founder builds a product millions of people freely buy and ends up with $2 billion. Should the state tax a large share of it to fund schools and healthcare for the poorest?

Notice that the theories don't just disagree on the answer. They disagree on what kind of question it is: about outcomes, about history, about capabilities, or about what a community values. That's why arguments about justice so often get nowhere. People think they're debating the answer when they're really debating the question.

The most useful thing you can learn about justice is not which theory is right, but which question each one is asking.

That's also why the debate stays live. Each tradition has answered the others' best objections in part, and none has answered them all. The best a careful citizen can do is know which question they're asking, and know the strongest objection to their own answer.

The takeaway

Plato made justice a matter of order: each part doing its own work, reason in charge. Aristotle made it proportional, to each according to merit, and showed that the fight is over which merit counts, judged by what a good is for. The utilitarians folded justice into overall well-being, which is impartial and gives a case for redistribution, but faces the charge that it ignores the separateness of persons. Rawls built two ranked principles for society's basic structure: equal liberties first, then fair opportunity, then inequalities only if they help the worst off. Nozick replied that justice is historical, that liberty upsets patterns, and that redistribution can violate rights; his critics replied that patterns can protect liberty and that real history is too dirty for his theory to bless the status quo. Sen and Nussbaum moved the focus to capabilities, what people can really do and be, and Sen argued for removing clear injustices rather than designing perfect ones. Sandel and the communitarians argued that justice can't be neutral about the good. None of these debates is closed.

Try this: pick one live policy question you care about (a minimum wage, an inheritance tax, a university admissions rule). Write one sentence stating how each of five thinkers would frame it: Aristotle (what is the good for?), Mill (what maximizes well-being?), Rawls (what helps the worst off, liberties first?), Nozick (what was the history?) and Sen (what does it do to people's real capabilities?). Then write the strongest objection to your own view, in the words of the thinker you most disagree with.
