Historical Context & Motivation
Political philosophy has long grappled with a fundamental question: what makes a society just? From Plato's philosopher-kings to Hobbes's sovereign authority, thinkers have proposed vastly different answers, each shaped by the assumptions and anxieties of their era. By the mid-twentieth century, the dominant framework in Anglo-American political philosophy was utilitarianism — the view that just institutions are those that maximize aggregate welfare or happiness. Yet utilitarianism faced persistent objections: it seemed to permit sacrificing the rights and well-being of minorities whenever doing so increased overall utility. It was in this intellectual landscape that John Rawls developed his landmark theory, seeking a systematic alternative grounded in fairness rather than maximization.
Rawls drew on the social contract tradition — the idea that legitimate political authority rests on an agreement among individuals — but radically reimagined it. Rather than positing a historical contract (as Locke did) or a hypothetical act of submission (as Hobbes did), Rawls constructed a purely hypothetical deliberative situation designed to guarantee impartial reasoning. The resulting device, the original position, became the centerpiece of his 1971 masterwork, A Theory of Justice, one of the most influential works of political philosophy published in the twentieth century.
The central question Rawls sought to address was deceptively simple: What principles of justice would free and rational persons choose to govern the basic structure of society if they had to choose from behind a veil of ignorance about their own particular circumstances? By stripping away knowledge of one's social position, natural talents, race, gender, and conception of the good life, Rawls aimed to ensure that the chosen principles would be genuinely fair — untainted by self-interest or arbitrary advantage. This question, and the elaborate philosophical architecture Rawls built around it, remains a cornerstone of contemporary debates about distributive justice, human rights, and democratic governance.
Core Principles & Definitions
Rawls's theory rests on several interconnected concepts that together form a coherent framework for deriving principles of justice. Understanding each component is essential before examining how they work in concert. The framework is often described under the heading justice as fairness, a name Rawls chose deliberately to signal that the fairness of the procedure — the conditions under which principles are selected — guarantees the justice of the outcome.

Visual Explanation — The Architecture of the Original Position
The diagram above captures the essential logic of Rawls's construction. The original position is not a place one actually occupies but a standpoint from which to reason about justice. The veil of ignorance accomplishes a crucial philosophical task: it operationalizes the moral intuition that principles of justice should not be biased by morally arbitrary factors such as the accident of birth into a wealthy family or a particular ethnic group. By denying deliberators knowledge of such facts while allowing them to retain understanding of general social and psychological truths, Rawls ensures that they are both motivated to reach an agreement (since they know they will live under the chosen principles) and constrained to choose impartially.
Notice that the two resulting principles are ordered in what Rawls calls lexical priority: the first principle (equal basic liberties) must be fully satisfied before the second principle (governing social and economic inequalities) comes into play. This ordering reflects Rawls's conviction that fundamental freedoms — speech, conscience, political participation — cannot be traded away for economic gains, no matter how large. The second principle itself contains two parts: fair equality of opportunity and the difference principle, with the former taking priority over the latter.
How the Original Position Works — The Logic of Maximin
A critical question arises once we accept the setup of the original position: why would rational agents behind the veil choose Rawls's two principles rather than, say, utilitarian principles or libertarian ones? Rawls argues that the unique conditions of the original position — especially the profound uncertainty created by the veil of ignorance — make a particular decision rule rational: the maximin rule. This rule instructs agents to rank alternative principles by their worst possible outcomes and then choose the alternative whose worst outcome is the best (i.e., maximize the minimum).
The reasoning proceeds as follows. Behind the veil, you do not know whether you will end up as the wealthiest member of society or the poorest, as a member of a racial majority or a persecuted minority. Under utilitarianism, it is possible that the worst-off group could be severely disadvantaged if their suffering is outweighed by gains to the majority. Under Rawls's two principles, by contrast, the worst-off group is guaranteed equal basic liberties and a social system in which economic inequalities only exist insofar as they benefit the least advantaged members of society. A rational agent who cannot gauge probabilities and who faces potentially catastrophic outcomes would, Rawls contends, choose the safe option: the two principles.
The Two Principles of Justice in Detail
The Veil of Ignorance — What It Hides and Why
The veil of ignorance is the most distinctive and philosophically powerful element of Rawls's framework. It functions as a device of representation: it models in a concrete thought-experimental form the abstract moral requirement that principles of justice should not be influenced by morally arbitrary contingencies. To appreciate its force, it helps to examine precisely what the veil conceals and what it permits, and to consider why each exclusion matters.
Each item concealed behind the veil corresponds to a specific moral argument. Social position and class are hidden because being born wealthy or poor is a matter of luck, not desert; no one deserves the family they are born into. Natural talents are hidden for a parallel reason: genetic endowments are distributed by a natural lottery that has no moral significance. Race, gender, and one's conception of the good life are hidden to prevent majoritarian domination and to ensure that principles do not privilege any particular religion, culture, or lifestyle. Even one's generation is concealed to prevent generational selfishness — so that principles regarding savings and environmental stewardship are chosen fairly.
Crucially, what the veil retains is just as important as what it hides. If deliberators knew nothing at all, they could not reason about which principles would produce better social outcomes. By granting them knowledge of general social science, economics, and human psychology, Rawls ensures that the choice is informed and rational rather than arbitrary. The deliberators are, in effect, social scientists who understand how institutions shape life outcomes but who are stripped of any knowledge about their own place in the resulting institutional order.
Worked Example — Reasoning from Behind the Veil
To illustrate how the original position functions as a decision procedure, let us walk through a concrete deliberation. Imagine that the parties behind the veil must choose between two alternative sets of principles for organizing healthcare in their society.
Strengths, Limitations & Major Critiques
Rawls's original position has been extraordinarily influential, but it has also attracted a wide range of criticisms from across the political spectrum. Understanding these objections is essential for a nuanced appreciation of the theory's scope and limits. The table below summarizes the major strengths alongside the most prominent lines of critique.
| Dimension | Strengths | Critiques & Limitations |
|---|---|---|
| Impartiality | The veil guarantees that principles are not biased by morally arbitrary advantages. It operationalizes the deep moral intuition that justice should be blind to circumstance. | Communitarians (e.g., Sandel, MacIntyre) argue the veil strips away the very identities and attachments that make moral reasoning meaningful. An 'unencumbered self' behind the veil is a philosophical fiction. |
| Decision Rule | Maximin reasoning provides a clear, justified basis for risk-averse choice under conditions of radical uncertainty, protecting against catastrophic outcomes. | Harsanyi and others argue that rational agents would use expected utility maximization (probabilistic reasoning) rather than maximin, which could justify utilitarian principles instead. |
| Scope | The theory provides a comprehensive framework for evaluating the basic structure of society — constitutions, legal systems, and economic institutions. | Libertarians (e.g., Nozick) contend that justice concerns individual entitlements, not distributional patterns. The original position ignores how holdings were legitimately acquired. |
| Universality | By abstracting from cultural particulars, the theory aspires to cross-cultural applicability and has influenced international human rights discourse. | Feminist critics (e.g., Okin, Pateman) note that Rawls's original formulation paid insufficient attention to gender and family justice. Multicultural critics argue it privileges liberal Western assumptions. |
| Practical Relevance | The theory has directly influenced constitutional design, welfare policy, and debates about healthcare, education, and taxation in democratic societies. | Sen and capability theorists argue that primary goods are too blunt a metric; what matters is what people can actually do and be (capabilities), not what they have. |
Connections to Advanced Theory & Later Developments
Rawls's original position did not emerge in a vacuum, nor did it remain static after 1971. Understanding its relationship to earlier contractarian thought and to Rawls's own later revisions illuminates its evolving place in political philosophy. The table below compares the original position as presented in A Theory of Justice with key modifications Rawls introduced in Political Liberalism (1993) and Justice as Fairness: A Restatement (2001).
| Feature | A Theory of Justice (1971) | Political Liberalism (1993) |
|---|---|---|
| Justification | Justice as fairness is presented as a comprehensive moral doctrine — true for all persons as a matter of moral philosophy. | Justice as fairness is reframed as a political conception that can be the subject of an overlapping consensus among citizens who hold diverse comprehensive doctrines. |
| Parties' Motivation | Parties are modeled as mutually disinterested rational agents pursuing primary goods. | Parties are additionally understood as representatives of free and equal citizens who possess two moral powers: a capacity for a sense of justice and a capacity for a conception of the good. |
| Stability | Stability is argued via moral psychology: people raised under just institutions develop a sense of justice. | Stability is argued via the idea of overlapping consensus and public reason, acknowledging the fact of reasonable pluralism. |
| Scope | Primarily domestic — focused on a closed, self-sufficient society. | Still domestic, but later extended to international relations in The Law of Peoples (1999), with a modified original position for relations among 'peoples' rather than individuals. |
Rawls's revisions were driven in part by what he called the fact of reasonable pluralism — the recognition that in a free society, citizens will inevitably hold diverse and incompatible religious, philosophical, and moral doctrines. The original position needed to be reinterpreted not as a device for discovering universal moral truths but as a political construction that could command the allegiance of citizens from many different moral traditions. This shift from comprehensive liberalism to political liberalism is one of the most significant developments in late-twentieth-century political theory.
Beyond Rawls's own revisions, the original position has inspired a wide range of successor theories. T.M. Scanlon's contractualism reimagines the contractual device as a search for principles no one could reasonably reject. Amartya Sen and Martha Nussbaum's capability approach retains Rawls's concern with the worst-off but replaces primary goods with capabilities as the evaluative metric. And in applied ethics, Rawlsian reasoning continues to shape debates about healthcare justice, educational equity, climate justice, and algorithmic fairness — wherever the challenge is to design institutions that are justifiable to all.
Practice Problems
Summary — Rawls's Original Position & Veil of Ignorance
John Rawls's original position is a hypothetical deliberative situation in which rational agents choose principles of justice for the basic structure of society from behind a veil of ignorance that conceals all morally arbitrary particular facts — race, class, gender, talents, and conceptions of the good — while retaining general knowledge of social science and the circumstances of justice. The framework is grounded in the social contract tradition (Hobbes, Locke, Rousseau, Kant) but transforms it into a purely hypothetical procedure for deriving fair principles, a method Rawls calls justice as fairness.
Using maximin reasoning — choosing the option whose worst-case outcome is best — deliberators arrive at two lexically ordered principles: (1) the equal liberty principle, guaranteeing the most extensive scheme of equal basic liberties compatible with similar liberty for all, and (2) the requirement that social and economic inequalities satisfy fair equality of opportunity and the difference principle (benefiting the least advantaged). Major critiques come from communitarians (the veil strips away identity), libertarians (justice is about entitlements, not patterns), and utilitarians (expected utility maximization rather than maximin). Rawls later revised the theory in Political Liberalism, reframing justice as fairness as a political rather than comprehensive doctrine, responsive to the fact of reasonable pluralism.
