What would fair institutions have to protect?

Beyond a fair hearing

Imagine a city reconsidering its rules for property, education and political participation. One resident asks whether the proposals will make the city richer. Another asks what people will be allowed to keep. A third wants to know whether she will be able to reach a classroom, or enter the public hall at all.

The previous lesson asked whose account receives a fair hearing. Suppose now that everyone has been heard: the city still needs reasons for deciding which arrangements are just. John Rawls, Robert Nozick and Amartya Sen help us distinguish three questions that a table of everyone’s income cannot settle.

Choosing without knowing your place

Rawls’s original position is an imagined situation for choosing principles for society’s basic structure: its major political, economic and social institutions. A veil of ignorance sets aside knowledge of one’s class, talents and idea of a good life, and of the particular circumstances of one’s society and generation. General knowledge of human needs and social cooperation remains. The aim is to keep advantages of birth or circumstance from deciding the terms. [1]

Behind this veil, “My family owns the land, so landowners should control the council” carries no weight, while a reason about what secure rights let anyone do still can. You must weigh arrangements without knowing whose advantages will turn out to be yours.

Hobbes and Locke used a state of nature, a condition without shared political authority, to examine government and consent. Rawls’s imagined agreement does something different: it selects standards for institutions and records nobody’s actual consent. Kant’s autonomy, giving oneself a rational law instead of simply following preference, offers a useful comparison, because it too asks for a reason that reaches beyond one’s private advantage. Still, the two tests have different tasks.

The construction is a model of fair reasoning. We can dispute its restrictions, or accept them and still dispute the principles Rawls thinks they support. [4]

What the principles protect

Rawls gives equal basic liberties, such as freedom of speech and conscience, priority over economic gains; each person must have liberties compatible with the same liberties for others. His second principle requires fair equality of opportunity and permits inequalities only when they work to the greatest benefit of the least advantaged, subject to provision for future generations. Fair opportunity comes before this difference principle.

To compare people’s positions, Rawls uses primary social goods. These include rights, opportunities, income, wealth and the social bases of self-respect: the conditions that support a sense of one’s own worth. [1]

Fair opportunity requires comparable prospects for people with similar abilities and willingness to use them, whatever their social class; announcing that anyone may apply is not enough. [1] Nor does increasing total wealth by itself satisfy the difference principle, which compares the position of the least advantaged under feasible institutional alternatives. [4]

Suppose one proposed economic arrangement leaves the least advantaged better off than another does. That matters. But a proposal that buys those gains by denying a minority the vote has already failed an earlier requirement, and no higher income can purchase away their equal political standing. Mill’s question about well-being and liberty returns here, with the reasons in a different order.

Nozick asks how holdings arose

For Nozick, entitlement is a justified claim to what one holds. It depends on the just acquisition of previously unowned things, just transfers between people, and rectification, the repair of past injustice. An unequal result alone does not tell us whether those requirements were met. [2]

His Wilt Chamberlain example begins with a distribution accepted as just. Fans voluntarily pay to watch the basketball player, and he becomes much richer. If they were entitled to transfer their money, why does the resulting inequality authorize taking it away? Maintaining a prescribed pattern can require restricting transfers or repeatedly undoing their effects. [2]

The starting assumption matters: theft, enslavement or fraud does not become just through a later sale. Rectification is part of his theory, although this selection leaves its detailed requirements undeveloped. [2] Cugoano’s challenge to purchase as justification gives an earlier, distinct reason to ask what a seller was entitled to transfer.

Where the disagreement lies

A Rawlsian need not demand that every exchange preserve equal holdings, because the principles govern the institutional rules under which transactions take place. Nozick’s challenge presses on the justification for the constraints those rules impose on people’s choices, and his discussion explicitly anticipates an appeal to background institutions. [2] [4]

In our city, calling a payment voluntary still leaves a question about the rules surrounding it, and calling a rule beneficial leaves a question about whose claims it overrides. Rawls and Nozick disagree over what makes a rule legitimate. Both care about liberty, so invoking the word cannot decide between them.

Sen asks what the goods make possible

Sen’s capability objection changes the measure of advantage. A capability concerns what someone is actually able to do, such as move about, obtain nourishment or take part in community life. People can possess similar resources yet differ greatly in their ability to use them. Satisfaction also misses some needs, since adapting cheerfully to a restriction does not remove it. [3]

Imagine a variation on the Mill lesson’s public-hall case. Two residents have equal incomes and equal rights of admission, but one uses a wheelchair and the only entrance has steps. Their equal tickets conceal unequal access, and raising both incomes by the same amount may leave the obstacle untouched. A usable entrance changes what the resident can do, whether or not she chooses to attend tonight.

Rawls’s goods already extend beyond money. Sen’s objection is that even this broader measure can miss differences in what people are able to do with their means. The objection concerns what a fair comparison must measure; it does not make the distribution of resources unimportant. Selecting and weighing capabilities remains difficult, and Sen presents a partial guide rather than a complete account of justice. [3]

Try the city’s argument

A councilor says, “Behind the veil we must ignore disability. Equal incomes will therefore settle fairness. And if everyone agrees to a sale, its history no longer matters.” Explain the gaps in this reasoning. What further information would help assess the hall? This exercise is optional.

Read a possible response

Setting aside knowledge of one’s own position does not erase general knowledge about differing human needs. The councilor has turned a restriction on choosing principles for one’s own advantage into a ban on relevant reasoning. Equal incomes also leave rights and opportunities unexamined: the residents still need to ask what their institutions enable and protect.

A ticket does little for someone stopped at the door. Investigating the entrances, the transport and the resident’s own account would help distinguish an opportunity she can use from a permission on paper. None of this requires anyone to attend, or assigns a value to anyone’s life according to physical ability.

Agreement to a sale cannot show that the seller had a rightful claim; records of acquisition and of earlier coercion may matter. Such evidence can expose a missing premise without settling every dispute about repair or funding. These answers test distinctions; they do not require choosing one of the three theories.

Carry this forward

An income table can reveal inequality while leaving its history, its governing rules and its practical consequences unclear. Ask what is being compared and what would count as a reason for changing it. The next lesson, What disappears when dependency is treated as an exception?, asks what justice requires when people need care and others provide it.
