A Theory of Justice

In 1971, philosopher John Rawls published a groundbreaking work that redefined modern political thought. "A Theory of Justice" presented a powerful alternative to prevailing ideas, daring to ask: How can we design a society that is truly fair for everyone, especially the least advantaged? Rawls's answer lies in a brilliant thought experiment that continues to provoke debate and inspire visions of a more just world. Rawls proposed a framework for a just society that prioritizes individual liberties and allows inequalities only if they benefit the worst-off. The core of his theory is the 'Original Position' behind a 'veil of ignorance,' where unbiased individuals choose principles for society. His work sparked a renaissance in political philosophy, leading to widespread engagement, critique, and refinement of theories of justice.

In 1971, philosopher John Rawls published a groundbreaking work that redefined modern political thought. "A Theory of Justice" presented a powerful alternative to prevailing ideas, daring to ask: How can we design a society that is truly fair for everyone, especially the least advantaged? Rawls's answer lies in a brilliant thought experiment that continues to provoke debate and inspire visions of a more just world.

Reimagining Justice

Published in 1971, John Rawls's "A Theory of Justice" wasn't just another book—it was a seismic event in political philosophy. Rawls aimed to offer a compelling moral theory that could rival utilitarianism, a dominant school of thought that often prioritized the greatest good for the greatest number, even at the expense of individuals. Instead, Rawls wanted to rigorously address the fundamental problem of distributive justice: how should a society fairly distribute its resources, opportunities, and burdens among its members?

Drawing inspiration from the philosophical giants before him, Rawls fused an updated form of Kantian philosophy with a reimagined social contract theory. His goal was to build a robust political theory of justice that could provide concrete principles for the 'basic structure' of a well-ordered society, ensuring a principled reconciliation of liberty and equality for all.

The Original Position: A Thought Experiment

To achieve this, Rawls devised one of philosophy's most famous thought experiments: the 'Original Position.' Imagine a group of rational individuals gathered to decide the fundamental rules of their future society. What principles would they choose to govern everything from political rights to economic distribution?

Crucially, these individuals are placed behind a 'veil of ignorance.' This veil blinds them to all personal facts about themselves: their race, gender, class, natural talents, intelligence, even their personal values or conception of a good life. They don't know if they'll be rich or poor, healthy or sick, powerful or marginalized.

The genius of the veil is its impartiality. Stripped of all self-serving knowledge, individuals in the Original Position cannot tailor principles to their own advantage. If you don't know whether you'll be at the top or bottom of society, Rawls argued, you'll naturally choose principles that protect everyone, especially the most vulnerable.

Behind this veil, Rawls believed these rational, self-interested, yet mutually disinterested individuals — who understand the realities of moderate scarcity and the need for cooperation — would unanimously agree upon two core principles of justice. These principles, he contended, would be far more compelling than those offered by utilitarian or libertarian alternatives.

Rawls's Two Principles of Justice

Rawls refined his principles throughout his work, but their final formulation remains the cornerstone of his theory. They are presented in a strict 'lexical order,' meaning the first principle must be satisfied before the second, and the second's first part before its second part. No amount of social or economic benefit can justify violating a prior principle.

1. Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with a similar system of liberty for all. 2. Social and economic inequalities are to be arranged so that they are both: (a) to the greatest benefit of the least advantaged, and (b) attached to offices and positions open to all under conditions of fair equality of opportunity.

The Greatest Equal Liberty Principle (Principle 1)

This first principle, often called the 'greatest equal liberty principle,' asserts the absolute priority of fundamental freedoms. It guarantees that every person has the most extensive system of basic liberties possible, as long as it doesn't infringe upon the same liberties for others. These aren't just any freedoms, but specific, crucial ones.

Rawls identifies these basic liberties as including political liberty (like the right to vote and hold public office), freedom of speech and assembly, liberty of conscience and thought, freedom of the person (protection from assault), the right to hold personal property, and freedom from arbitrary arrest as defined by the rule of law. Notably, he argues that economic liberties like 'freedom of contract' or 'laissez-faire' aren't among these basic, non-negotiable rights.

The Fair Equality of Opportunity Principle (Principle 2b)

The second part of the second principle, 'fair equality of opportunity,' comes next in lexical priority. It dictates that social and economic positions should not only be formally open to all—meaning no legal barriers—but that everyone should have a fair chance to attain them. This means that factors like one's social class or family background shouldn't determine life prospects.

This principle implies that society must actively work to mitigate the effects of morally arbitrary factors, such as being born into poverty. It requires robust public education and other measures to ensure that individuals, regardless of their starting point, have a genuine opportunity to develop their talents and compete for desirable positions.

The Difference Principle (Principle 2a)

Finally, we arrive at the 'difference principle.' This is perhaps Rawls's most distinctive and debated contribution. It states that social and economic inequalities are permissible only if they ultimately benefit the least advantaged members of society. In other words, if an unequal distribution makes the worst-off better off than they would be under an equal distribution, then it is just.

Rawls argues this principle reflects a 'maximin strategy' from the Original Position: maximize the minimum. If you don't know your place, you'd want to ensure that even if you ended up at the bottom, your situation would be as good as possible. This principle challenges traditional meritocracy by asserting that while talent can generate wealth, that wealth must serve the common good, particularly the well-being of those with the fewest advantages.

Rawls further incorporated a 'just savings principle,' suggesting that each generation has an obligation to save some material resources for future generations. This ensures that the pursuit of justice is not short-sighted but considers the long-term well-being of the entire societal lineage.

A Hypothetical Agreement

It's important to remember that the agreement reached in the Original Position is both hypothetical and ahistorical. It's not something that has ever happened in reality, nor is it expected to. Instead, it's a powerful tool for moral reasoning—a way to think about what principles free and equal citizens would choose if they were truly impartial.

This thought experiment gives moral weight to the principles, allowing us to evaluate existing societal structures against an ideal standard derived from a fair choice situation. Rawls believed that by stepping behind the veil, we could uncover the fundamental principles that should guide our collective life.

Reception and Enduring Legacy

"A Theory of Justice" was immediately recognized as a monumental achievement. Reviewers like Marshall Cohen hailed it as "magisterial," a "bold and rigorous" defense of the social contract tradition that proved systematic moral philosophy was far from dead. Many compared Rawls's impact to that of historical giants like John Stuart Mill and Immanuel Kant.

However, such an ambitious work inevitably drew extensive criticism, which Rawls often engaged with, leading to further refinements of his theory. Libertarian philosopher Robert Nozick, for instance, challenged Rawls's concept of distributive justice, arguing for individual property rights over patterns of distribution.

Marxist critics like Robert Paul Wolff argued that Rawls's theory, despite its egalitarian aims, ultimately served as an apology for the capitalist status quo, failing to address inherent injustices embedded in private property and market economies. Other critics like Allan Bloom praised its ambition but critiqued its "radical egalitarian interpretation" and perceived failure to account for natural rights.

Communitarians like Michael Sandel argued that Rawls's emphasis on individuals behind a veil of ignorance encouraged a detached view of justice, divorced from the rich values and aspirations that define people and communities. Feminist philosopher Susan Moller Okin, while acknowledging its influence, criticized the theory for overlooking injustices and hierarchies within family relations.

Economists Kenneth Arrow and John Harsanyi questioned the rationality of using a maximin strategy in the Original Position, suggesting that Rawls's parameters might have been chosen to lead to his desired principles. Rawls, in response, clarified that the Original Position was a "device of representation" and maximin a "useful heuristic rule of thumb" rather than a rigid logical dictate.

More recently, philosopher Charles W. Mills offered a powerful critique in "Black Rights / White Wrongs," arguing that Rawls's "ideal theory" of justice operates within a "white fantasy world," fundamentally blind to the historical realities and ongoing injustices of racial oppression. Mills called for a "non-ideal theory" urgently needed to address racial inequality.

Even allies offered constructive critiques. Nobel laureate Amartya Sen questioned Rawls's focus on primary social goods, arguing that true justice requires considering how effectively people can use those goods to pursue their own ends. Sen later, in "The Idea of Justice," praised Rawls for revitalizing interest in justice and fairness, yet critiqued his overemphasis on institutions, arguing that human behavior's impact on a just society was understated.

Despite—or perhaps because of—the vigorous debate it continues to inspire, "A Theory of Justice" remains a foundational text. It anchors contemporary discussions about social justice, equality, and liberty, influencing fields far beyond philosophy, from law and economics to political science and public policy. Its enduring power lies in its audacious attempt to provide a rational, moral blueprint for a truly fair society.

And for a lighter note on its impact, the theory even inspired a 2013 musical, "A Theory of Justice: The Musical!"—proving that profound philosophical ideas can sometimes find their way onto the most unexpected stages.

Article

A Theory of Justice

A Theory of Justice is a 1971 work of political philosophy and ethics by the philosopher John Rawls (1921–2002) in which the author attempts to provide a moral theory alternative to utilitarianism and that addresses the problem of distributive justice (the socially just distribution of goods in a society). The theory uses an updated form of Kantian philosophy and a variant form of conventional social contract theory. Rawls's theory of justice is fully a political theory of justice as opposed to other forms of justice discussed in other disciplines and contexts.

The resultant theory was challenged and refined several times in the decades following its original publication in 1971. A significant reappraisal was published in the 1985 essay "Justice as Fairness" and the 2001 book Justice as Fairness: A Restatement in which Rawls further developed his two central principles for his discussion of justice. Together, they assert that society should be structured to provide the greatest possible degree of liberty to its members, limited only by the principle that one individual's liberty must not infringe upon the liberty of others. Secondly, inequalities – either social or economic – are only to be allowed if the worst off will be better off than they might be under an equal distribution. Finally, if an inequality is to be justified on the grounds of its benefits, it must not create additional barriers for those without resources to access positions of power, such as public office.

Objective

A Theory of Justice

In A Theory of Justice, Rawls argues for a principled reconciliation of liberty and equality that is meant to apply to the basic structure of a well-ordered society. Central to this effort is an account of the circumstances of justice, inspired by David Hume, and a fair choice situation for parties facing such circumstances, similar to some of Immanuel Kant's views. Principles of justice are sought to guide the conduct of the parties. These parties are recognized to face moderate scarcity, and they are neither naturally altruistic nor purely egoistic. They have ends which they seek to advance but prefer to advance them through cooperation with others on mutually acceptable terms. Rawls offers a model of a fair choice situation (the original position with its veil of ignorance) within which parties would hypothetically choose mutually acceptable principles of justice. Under such constraints, Rawls believes that parties would find his favoured principles of justice to be especially attractive, winning out over varied alternatives, including utilitarian and right-wing libertarian accounts.

The "original position"

A Theory of Justice

Rawls belongs to the social contract tradition, although he takes a different view from that of previous thinkers. Specifically, Rawls develops what he claims are principles of justice through the use of an artificial device or thought experiment he calls the Original position; in which, everyone decides principles of justice from behind a veil of ignorance. This "veil" is one that essentially blinds people to all facts about themselves so they cannot tailor principles to their own advantage:

[N]o one knows his place in society, his class position or social status, nor does anyone know his fortune in the distribution of natural assets and abilities, his intelligence, strength, and the like. I shall even assume that the parties do not know their conceptions of the good or their special psychological propensities. The principles of justice are chosen behind a veil of ignorance.

According to Rawls, ignorance of such details enable the isolation of principles around which the structure of a fair society can be agreed upon:

They are the principles that rational and free persons concerned to further their own interests would accept in an initial position of equality as defining the fundamentals of the terms of their association.

If an individual does not know how he will end up in his own conceived society, he is likely not going to privilege any one class of people, but rather develop a scheme of justice that treats all fairly.

In particular, Rawls claims that those in the Original Position would adopt two principles, the second of which is a maximin strategy which would maximize the prospects of the least well-off.

Rawls bases his Original Position on a "thin theory of the good" which he says "explains the rationality underlying choice of principles in the Original Position". A full theory of the good follows after we derive principles from the original position. Rawls claims that the parties in the original position would adopt two such principles, which would then govern the assignment of rights and duties and regulate the distribution of social and economic advantages across society. The difference principle permits inequalities in the distribution of goods only if those inequalities benefit the worst-off members of society. Rawls believes that this principle would be a rational choice for the representatives in the original position for the following reason: Each member of society has an equal claim on their society's goods. Natural attributes should not affect this claim, so the basic right of any individual, before further considerations are taken into account, must be to an equal share in material wealth. What, then, could justify unequal distribution? Rawls argues that inequality is acceptable only if it is to the advantage of those who are worst-off.

The agreement that stems from the original position is both hypothetical and ahistorical. It is hypothetical in the sense that the principles to be derived are what the parties would, under certain legitimating conditions, agree to, not what they have agreed to. Rawls seeks to use an argument that the principles of justice are what would be agreed upon if people were in the hypothetical situation of the original position and that those principles have moral weight as a result of that. It is ahistorical in the sense that it is not supposed that the agreement has ever been, or indeed could ever have been, derived in the real world outside of carefully limited experimental exercises.

The principles of justice

A Theory of Justice

Rawls modifies and develops the principles of justice throughout his book. In chapter forty-six, Rawls makes his final clarification on the two principles of justice:

1. Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with a similar system of liberty for all. 2. Social and economic inequalities are to be arranged so that they are both:

The first principle is often called the greatest equal liberty principle. Part (a) of the second principle is referred to as the difference principle while part (b) is referred to as the equal opportunity principle.

Rawls orders the principles of justice lexically, as follows: 1, 2b, 2a. The greatest equal liberty principle takes priority, followed by the equal opportunity principle and finally the difference principle. The first principle must be satisfied before 2b, and 2b must be satisfied before 2a. As Rawls states: "A principle does not come into play until those previous to it are either fully met or do not apply." Therefore, the equal basic liberties protected in the first principle cannot be traded or sacrificed for greater social advantages (granted by 2(b)) or greater economic advantages (granted by 2a).

The greatest equal liberty principle

Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with a similar system of liberty for all (1).

The greatest equal liberty principle is mainly concerned with the distribution of rights and liberties. Rawls identifies the following equal basic liberties: "political liberty (the right to vote and hold public office) and freedom of speech and assembly; liberty of conscience and freedom of thought; freedom of the person, which includes freedom from psychological oppression and physical assault and dismemberment (integrity of the person); the right to hold personal property and freedom from arbitrary arrest and seizure as defined by the concept of the rule of law."

It is a matter of some debate whether freedom of contract can be inferred to be included among these basic liberties: "liberties not on the list, for example, the right to own certain kinds of property and freedom of contract as understood by the doctrine of laissez-faire are not basic; and so they are not protected by the priority of the first principle.".

The difference principle

Social and economic inequalities are to be arranged so that they are (a) to the greatest benefit of the least advantaged members of society, consistent with the just savings principle (2a).

Rawls' claim in (a) is that departures from equality of a list of what he calls primary goods—"things which a rational man wants whatever else he wants" are justified only to the extent that they improve the lot of those who are worst-off under that distribution in comparison with the previous, equal, distribution. His position is at least in some sense egalitarian, with a provision that inequalities are allowed when they benefit the least advantaged. An important consequence of Rawls' view is that inequalities can actually be just, as long as they are to the benefit of the least well off. His argument for this position rests heavily on the claim that morally arbitrary factors (for example, the family one is born into) should not determine one's life chances or opportunities. Rawls is also oriented to an intuition that a person does not morally deserve their inborn talents; thus, that one is not entitled to all the benefits they could possibly receive from them; hence, at least one of the criteria which could provide an alternative to equality in assessing the justice of distributions is eliminated.

Further, the just savings principle requires that some sort of material respect is left for future generations. Although Rawls is ambiguous about what this means, it can generally be understood as "a contribution to those coming later".

The equal opportunity principle

Social and economic inequalities are to be arranged so that they are (b) attached to offices and positions open to all under conditions of fair equality of opportunity (2b).

The stipulation in 2b is lexically prior to that in 2a. This is because equal opportunity requires not merely that offices and positions are distributed on the basis of merit, but that all have reasonable opportunity to acquire the skills on the basis of which merit is assessed, even if one might not have the necessary material resources - due to a beneficial inequality stemming from the difference principle.

It may be thought that this stipulation, and even the first principle of justice, may require greater equality than the difference principle, because large social and economic inequalities, even when they are to the advantage of the worst-off, will tend to seriously undermine the value of the political liberties and any measures towards fair equality of opportunity.

Influence and reception

A Theory of Justice

In 1972, A Theory of Justice was reviewed in The New York Times Book Review by Marshall Cohen, who described the work as "magisterial," and suggested that Rawls' use of the techniques of analytic philosophy made the book the "most formidable" defense of the social contract tradition to date. He credited Rawls with showing that the widespread claim that "systematic moral and political philosophy are dead" is mistaken, and with providing a "bold and rigorous" account of "the principles to which our public life is committed." Though he suggested that it might take years before a satisfactory appraisal of the work could be made, he noted that Rawls' accomplishments had been compared by scholars to those of John Stuart Mill and Immanuel Kant. However, he criticized Rawls for "looseness in his understanding of some fundamental political concepts."

A Theory of Justice received criticism from several philosophers. Robert Nozick criticized Rawls' account of distributive justice in his defense of libertarianism, Anarchy, State, and Utopia (1974). Allan Bloom, writing in American Political Science Review in 1975, noted that A Theory of Justice had "attracted more attention in the Anglo-Saxon world than any work of its kind in a generation", attributing its popularity to its being "the most ambitious political project undertaken by a member of the school currently dominant in academic philosophy" and to Rawls’s "radical egalitarian interpretation of liberal democracy." Bloom criticized Rawls for failing to account for the existence of natural right in his theory of justice and wrote that Rawls absolutizes social union as the ultimate goal which would conventionalize everything into artifice. Robert Paul Wolff criticized Rawls from a Marxist perspective in Understanding Rawls: A Critique and Reconstruction of A Theory of Justice (1977), arguing Rawls offers an apology for the status quo insofar as he constructs justice from existing practice and forecloses the possibility that there may be problems of injustice embedded in capitalist social relations, private property or the market economy.

Michael Sandel criticized Rawls in Liberalism and the Limits of Justice (1982), arguing that Rawls encourages people to think about justice while divorced from the values and aspirations that define who they are as persons and that allow people to determine what justice is. Susan Moller Okin wrote in Justice, Gender, and the Family (1989) that Rawls had provided "the most influential of all twentieth-century theories of justice", but criticized him for failing to account for the injustices and hierarchies embedded in familial relations. Economists Kenneth Arrow and John Harsanyi criticized the assumptions of the original position, and in particular, the use of maximin reasoning, with the implication that Rawls' selection of parameters for the original position was result-oriented, i.e., calculated to derive the two principles that Rawls desired to advance, and/or, as the "contractarian critique" holds, that the persons in the original position articulated by Rawls would not in fact select the principles that A Theory of Justice advocates. In reply Rawls emphasized the role of the original position as a "device of representation" for making sense of the idea of a fair choice situation for free and equal citizens, and that the relatively modest role that maximin plays in his argument: it is "a useful heuristic rule of thumb" given the curious features of choice behind the veil of ignorance.

In his book Black Rights / White Wrongs, philosopher Charles W. Mills critiques the underlying assumptions of Rawls’s work as inherently white, and thus subject to glaring blind spots. Mills sets “the white fantasy world of Rawlsianism” and its “ideal theory” against the actual history of racialized oppression in the modern era, and proposes that non-ideal theory is urgently needed to address racial inequality and possible remediations. “Here is a huge body of work," Mills writes on Rawls's output, "focused on questions of social justice – seemingly the natural place to look for guidance on normative issues related to race – which has nothing to say about racial justice, the distinctive injustice of the modern world.” Mills identified what he described as a "pattern of silence" on issues of race in Rawls's work and situated it within a broader critique of the treatment of race in modern political philosophy.

The economist Amartya Sen has raised concerns over Rawls' emphasis on primary social goods, arguing in Inequality Reexamined (1992) that we should attend not only to the distribution of primary goods, but also how effectively people are able to use those goods to pursue their ends. Norman Daniels has wondered why health care should not be treated as a primary good, and some of his subsequent work has addressed this question, arguing for a right to health care within a broadly Rawlsian framework. Sen critiques and attempts to revitalize A Theory of Justice in The Idea of Justice (2009). He credits Rawls for revitalizing the interest in the ideas of what justice means and the stress put on fairness, objectivity, equality of opportunity, removal of poverty, and freedom. However, Sen, as part of his general critique of the contractarian tradition, states that ideas about a perfectly just world do not help redress actual existing inequality. Sen faults Rawls for overemphasizing institutions as guarantors of justice and not considering the effects of human behaviour on the institutions' ability to maintain a just society. Sen believes Rawls understates the difficulty in getting everyone in society to adhere to the norms of a just society. He also claims that Rawls' position that there be only one possible outcome of the reflective equilibrium behind the veil of ignorance is misguided. In contrast to Rawls, Sen believes that multiple conflicting, yet just, principles may arise and that this undermines the multistep processes that Rawls laid out as leading to a perfectly just society.

The philosopher G. A. Cohen, in If You're An Egalitarian, How Come You're So Rich? (2000) and Rescuing Justice and Equality (2008), criticizes Rawls' avowal of inequality under the difference principle, his application of the principle only to social institutions, and what he sees as Rawls's obsession with using primary goods as his currency of equality. Cohen argued that Rawls's principles of justice are influenced by assumptions about social institutions and human behaviour. He maintained that a theory of justice should identify principles that are fundamentally just independently of practical considerations, and therefore contended that Rawls's account was not a theory of justice in the strict sense.

In popular culture

A Theory of Justice

A Theory of Justice inspired a 2013 musical, A Theory of Justice: The Musical!, written and produced by Eylon Levy, Ramin Sabi, Tommy Peto, and Toby Huelin.
