A Theory of Justice

1. Justice as Fairness: A Social Contract for a Well-Ordered Society

Justice is the first virtue of social institutions, as truth is of systems of thought.

Foundational Virtue. John Rawls posits justice as the paramount virtue for any society, arguing that laws and institutions, regardless of their efficiency, must be reformed or abolished if they are unjust. This conviction stems from the inherent inviolability of each person, which cannot be overridden by the collective welfare. A just society, therefore, secures the liberties of equal citizenship, making them immune to political bargaining or the calculus of social interests.

Cooperative Venture. Society is understood as a cooperative venture for mutual advantage, where individuals recognize binding rules of conduct. While cooperation creates benefits for all, there's an inherent conflict of interests regarding how these benefits are distributed. Principles of social justice are thus essential to assign rights and duties within basic institutions and to define appropriate distributive shares, ensuring a fair division of advantages.

Well-Ordered Society. A society is "well-ordered" when it not only advances its members' good but is also effectively regulated by a public conception of justice. This means everyone accepts and knows that others accept the same principles, and basic institutions visibly satisfy these principles. This shared understanding fosters civic friendship and limits the pursuit of other ends, forming the fundamental charter of human association, even if perfect agreement is rarely achieved in practice.

2. The Original Position and Veil of Ignorance Ensure Impartiality

The principles of justice are chosen behind a veil of ignorance.

Hypothetical Agreement. Rawls generalizes the traditional social contract theory by introducing the "original position" – a purely hypothetical situation where free and rational persons, concerned with their own interests, would agree on the fundamental terms of their association. This initial position is designed to ensure that the principles chosen are fair, serving as the object of an original agreement rather than a historical event.

The Veil's Purpose. Crucially, the parties in the original position are placed behind a "veil of ignorance." This means they do not know their place in society, social status, natural talents, intelligence, or even their conception of the good. They are also unaware of their society's economic or political situation, or their generation. This informational blackout ensures that no one can design principles to favor their particular condition, making the agreement truly fair and unbiased by arbitrary contingencies.

Rational Choice. Despite the lack of specific information, the parties are rational and mutually disinterested. They know general facts about human society, political affairs, and economic theory. They are assumed to prefer more primary social goods (rights, liberties, opportunities, income, wealth, self-respect) rather than less, as these are necessary for any rational life plan. This limited knowledge allows them to make a rational decision, ensuring the chosen principles are acceptable from a moral point of view.

3. Two Principles of Justice: Liberty and Fair Equality for All

Social and economic inequalities are to be arranged so that they are both (a) to the greatest benefit of the least advantaged, consistent with the just savings principle, and (b) attached to offices and positions open to all under conditions of fair equality of opportunity.

First Principle: Equal Liberty. 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. These basic liberties include:

• Political liberty (right to vote, hold office)
• Freedom of speech and assembly
• Liberty of conscience and freedom of thought
• Freedom of the person (personal property, freedom from arbitrary arrest)
  This principle ensures that all citizens of a just society possess the same fundamental rights.

Second Principle: Social and Economic Inequalities. This principle governs the distribution of income, wealth, and positions of authority. It states that inequalities are just only if they meet two conditions:

• Difference Principle: They must be to the greatest benefit of the least advantaged members of society, consistent with a just savings principle for future generations. This means that any increase in the advantages of the better-off must also improve the prospects of the worst-off.
• Fair Equality of Opportunity: Offices and positions must be open to all under conditions that ensure everyone with similar abilities and motivation has similar life chances, regardless of their social background.

General Conception. These two principles are a special case of a more general conception: all social values—liberty and opportunity, income and wealth, and the bases of self-respect—are to be distributed equally unless an unequal distribution of any, or all, of these values is to everyone’s advantage. The two principles, arranged in a specific order, provide a more precise interpretation of this general idea.

4. The Priority of Liberty: Fundamental Freedoms Come First

The principles of justice are to be ranked in lexical order and therefore liberty can be restricted only for the sake of liberty.

Lexical Ordering. Rawls arranges his two principles in a "lexical order," meaning the first principle (equal basic liberties) must be fully satisfied before the second principle (social and economic inequalities) can come into play. This establishes the absolute priority of liberty: basic freedoms cannot be sacrificed or compensated for by greater social or economic advantages.

Liberty for Liberty's Sake. A basic liberty can only be limited for the sake of liberty itself. This occurs in two ways:

• Less Extensive Liberty: A narrower liberty must strengthen the total system of liberty shared by all (e.g., rules of order for free speech).
• Less Than Equal Liberty: An unequal liberty must be acceptable to those with the lesser liberty, meaning it must enhance their overall freedom (e.g., temporary restrictions to achieve a free society).
  This ensures that any curtailment of freedom is justified by a greater or more secure freedom for everyone, especially the disadvantaged.

Beyond Economic Gains. The priority of liberty reflects the idea that, once a certain level of economic well-being is attained, the marginal significance of further material advantages diminishes relative to the fundamental interest in liberty. Individuals in the original position would not trade their basic freedoms for more wealth, as self-respect and the ability to pursue a rational life plan become paramount. This ranking is the long-term tendency of a just society under favorable conditions.

5. Critique of Utilitarianism: It Fails to Respect the Distinction Between Persons

Utilitarianism does not take seriously the distinction between persons.

Aggregative Principle. Rawls argues that classical utilitarianism, which aims to maximize the total (or average) sum of satisfaction across society, fundamentally misunderstands justice. It treats society as if it were a single individual, extending the principle of rational choice for one person (balancing personal gains and losses over time) to the entire group. This "conflation of persons" allows for the possibility that the suffering of a few can be justified by the greater happiness of many.

Teleological Flaw. Utilitarianism is a teleological theory, defining the good (satisfaction of desire) independently of the right, and then defining the right as that which maximizes this good. This structure means that the distribution of satisfactions doesn't matter in itself, only the aggregate sum. Consequently, it offers no inherent protection for individual rights or liberties if their violation could lead to a greater overall good, making basic freedoms precarious.

Impersonality vs. Impartiality. The utilitarian concept of an "impartial sympathetic spectator" who imaginatively identifies with everyone's desires and sums them up, leads to impersonality, not true impartiality. In contrast, Rawls's original position, with its veil of ignorance and mutual disinterestedness, achieves impartiality by forcing individuals to choose principles that are fair to all distinct persons, without knowing their own specific interests. This ensures that the rights secured by justice are not subject to the calculus of social interests.

6. Pure Procedural Justice: Fair Processes Yield Fair Outcomes

Pure procedural justice obtains when there is no independent criterion for the right result: instead there is a correct or fair procedure such that the outcome is likewise correct or fair, whatever it is, provided that the procedure has been properly followed.

Defining Fairness. Rawls distinguishes between three types of procedural justice:

• Perfect Procedural Justice: An independent criterion for a fair outcome exists, and a procedure is guaranteed to achieve it (e.g., dividing a cake). This is rare in practice.
• Imperfect Procedural Justice: An independent criterion exists, but no feasible procedure is guaranteed to achieve it (e.g., a criminal trial).
• Pure Procedural Justice: No independent criterion for the right outcome exists; the outcome is fair because the procedure followed was fair (e.g., a fair gamble).

Background Institutions. For pure procedural justice to apply to distributive shares, a just system of background institutions must be established and impartially administered. This means the basic structure of society, including the political constitution and economic arrangements, must satisfy the two principles of justice. Only then can the outcomes of individual transactions, such as market exchanges, be considered just, whatever they happen to be.

Practical Advantage. The great practical advantage of pure procedural justice is that it eliminates the need to constantly track and evaluate the endless variety of individual circumstances and changing relative positions. Instead of focusing on allocative justice (dividing a fixed stock of goods), it focuses on designing a fair system of cooperation where legitimate expectations are honored, simplifying the problem of social justice.

7. The Just Savings Principle: Intergenerational Equity

The present generation cannot do as it pleases but is bound by the principles that would be chosen in the original position to define justice between persons at different moments of time.

Duty to Future Generations. The problem of justice between generations is crucial for determining the appropriate social minimum and the rate of capital accumulation. Rawls argues that the parties in the original position, not knowing which generation they belong to, would choose a "just savings principle" that assigns a suitable rate of accumulation to each stage of societal advance. This ensures that each generation contributes its fair share to realizing and preserving a just society.

No Pure Time Preference. The parties in the original position would reject "pure time preference," meaning they would not discount future well-being simply because it is in the future. The situation is symmetrical across generations, and favoring earlier periods over later ones based solely on temporal position would be arbitrary and unjust. This principle ensures an impartial concern for all parts of society's life span.

Constraint on Difference Principle. The just savings principle acts as a constraint on the difference principle. In any given generation, the expectations of the least advantaged are maximized, but only subject to the condition of putting aside the savings that would be acknowledged by the intergenerational agreement. This ensures that while current inequalities benefit the least advantaged now, they also contribute to the long-term well-being of future least advantaged groups, fostering a continuous process of improvement.

8. Moral Psychology: How a Sense of Justice Develops and Sustains Society

We develop a desire to apply and to act upon the principles of justice once we realize how social arrangements answering to them have promoted our good and that of those with whom we are affiliated.

Three Psychological Laws. Rawls outlines three psychological laws that explain how individuals in a well-ordered society acquire a sense of justice:

• Morality of Authority: Children develop love and trust for parents who manifestly love and care for them, leading to acceptance of parental injunctions and "authority guilt" when disobeyed.
• Morality of Association: As individuals participate in just associations (families, schools, communities) where others fulfill their duties, they develop friendly feelings and mutual trust, leading to "association guilt" when they fail to do their part.
• Morality of Principles: Recognizing that they and those they care for benefit from established and enduring just institutions, individuals acquire a "sense of justice," a desire to apply and act upon the principles of justice themselves, experiencing "principle guilt" for violations.

Reciprocity and Stability. These laws are principles of reciprocity: we acquire attachments to persons and institutions based on how we perceive our good to be affected by them. This tendency to "answer in kind" is a deep psychological fact essential for social cooperation. A well-ordered society, by publicly satisfying the principles of justice, fosters these sentiments, making the system inherently stable. The sense of justice, rooted in affirmation of self and reason, tends to override disruptive inclinations.

Clarity and Attractiveness. The stability of justice as fairness is enhanced by the clarity of its moral conception and the attractiveness of its ideals. The definite structure of the two principles makes them easier to understand and apply, securing their hold on the mind. Furthermore, the principles of justice, by guaranteeing equal liberties and ensuring that inequalities benefit the least advantaged, foster self-esteem and mutual respect, making adherence to them a desirable and rational choice for individuals.

9. The Basis of Equality: Moral Personality as the Foundation of Rights

The capacity for moral personality is a sufficient condition for being entitled to equal justice.

Defining the Scope of Justice. Rawls addresses the question of what features of human beings entitle them to be treated according to the principles of justice, distinguishing mankind from other living things. He identifies "moral personality" as the sufficient condition for equal justice, meaning that those who possess this capacity are owed the full guarantees of justice.

Two Capacities. Moral persons are characterized by two fundamental capacities:

• Conception of their Good: They are capable of having (and are assumed to have) a rational plan of life.
• Sense of Justice: They are capable of having (and are assumed to acquire) a normally effective desire to apply and act upon the principles of justice.
  This capacity is understood as a potentiality, meaning infants and children, who will ordinarily develop these capacities, are also entitled to equal justice.

Not Natural Attributes. Equality does not rest on the idea that all human beings are equal in some natural attribute (e.g., intelligence or strength), as such attributes vary. Instead, it rests on the shared capacity for moral personality, which is a "range property" – all who fall within this range are equally moral persons. This avoids the pitfalls of teleological theories that might justify unequal rights based on variations in capacity if it maximized some aggregate good.

10. The Good of Justice: Autonomy, Social Union, and a Congruent Life

The desire to act justly and the desire to express our nature as free moral persons turn out to specify what is practically speaking the same desire.

Congruence of Right and Good. The "good of justice" refers to the congruence between the principles of justice and a person's rational plan of life. In a well-ordered society, it is rational for individuals to affirm their sense of justice as regulative of their conduct. This means that acting justly is not merely a duty but is also part of one's own good, contributing to a fulfilling and meaningful life.

Autonomy and Objectivity. A well-ordered society fosters autonomy, as individuals act from principles they would choose as free and equal rational beings. Moral education is education for autonomy, enabling citizens to understand and accept justice on reasoned grounds. These principles are also objective, derived from a common standpoint (the original position) that everyone can adopt, ensuring impartiality and facilitating agreement.

Social Union and Self-Realization. Despite its individualistic starting point, justice as fairness accounts for the values of community. A well-ordered society is a "social union of social unions," where members share the final end of upholding just institutions, valuing them as good in themselves. Through cooperation, individuals participate in the "total sum of the realized natural assets of the others," appreciating diverse excellences and finding their own potentialities realized in the collective activity. This shared life, governed by justice, enhances self-respect and provides a framework for individual flourishing.
