Rawls's Original Position and Veil of Ignorance

Introduction

Welcome to our fourth lesson. In the previous lesson, we established a crucial distinction between John Locke's reliance on tacit consent and John Rawls's innovative use of hypothetical consent. We saw that for Rawls, political legitimacy isn't derived from what people have agreed to in the real world, but from what they would agree to in a specially designed, fair choice situation. His project is one of rational justification, not historical archaeology.

Today, we will open the hood and examine the engine of Rawls's theory. This lesson directly addresses the learning outcome: Analyze the function of the original position and the veil of ignorance in Rawls's 'A Theory of Justice'. We will treat this famous thought experiment not as a vague philosophical notion, but as a carefully specified model designed to solve a particular problem: how to select principles for the basic structure of society in a way that is free from bias.

We will break down this model into its key components:

• The Original Position (OP): The hypothetical setting for the contract.
• The Veil of Ignorance (VoI): The informational constraints placed upon the participants.
• The Parties to the Contract: The nature and motivation of the rational agents within the model.
• The Decision Rule: The rational strategy the parties use to make their choice.

Understanding this machinery is essential, as it provides the entire argumentative foundation for the principles of justice that Rawls derives—principles we will examine in our next lesson.

1. The Original Position: A Thought Experiment for Fair Choice

At its core, the Original Position is a thought experiment. Rawls asks us to imagine a group of individuals tasked with agreeing upon the fundamental principles of justice that will govern their society. As we established last time, this is a hypothetical, not a historical, event. Its purpose is to serve as a "device of representation"—a model that captures the conditions of a fair choice.

For a brief, elegant introduction to this idea, let's hear it described by the late legal philosopher Ronald Dworkin.

Dworkin's description highlights the key function: to model a fair choice. The core intuition is one of procedural justice, which you might recognize from other contexts. The simplest analogy is the principle for fairly dividing a cake: one person cuts, and the other person chooses their slice. The person cutting, not knowing which slice they will get, is incentivized to make the slices as equal as possible. The fairness of the procedure guarantees the fairness of the outcome. The Original Position is a sophisticated application of this same logic to the basic structure of society.

2. The Veil of Ignorance: Ensuring Impartiality

The most critical feature of the Original Position is the Veil of Ignorance. This is the mechanism that enforces fairness and impartiality by stripping the parties of information that could lead them to choose principles biased in their own favor.

To understand its function, we need to be precise about what information is filtered out and what remains.

As the video and Rawls's theory detail, behind the Veil of Ignorance, you do not know:

• Your place in society (class, wealth, social status).
• Your natural assets (intelligence, strength, talents).
• Your "conception of the good" (your values, life goals, religious or philosophical beliefs).
• Your psychological propensities (e.g., whether you are risk-averse or a gambler).
• Your race, gender, or other identifying social characteristics.
• The specific circumstances of your society (its economic development, culture, or history).

However, the parties are not completely ignorant. They do know:

• General facts about human psychology and society.
• Principles of economic theory and political science.
• The fact that society is under "circumstances of justice" (moderate scarcity and conflicting goals).
• That they will have some conception of the good, even if they don't know what it is.

The function of this carefully curated information set is to force the participants to reason from a universal, impartial perspective. Since you don't know if you will be rich or poor, talented or disadvantaged, a member of a majority or minority religion, you have a powerful incentive to choose principles that are fair to all possible positions in society.

For a deeper dive into the specific function of the veil, let's turn to the Stanford Encyclopedia of Philosophy (SEP).

The distinction between a "thick" and "thin" veil is crucial.

• A thin veil (used by some utilitarians) only hides your identity. You know the desires and preferences of everyone in society, you just don't know which person you will be. This leads to choosing principles that maximize average utility, as you're essentially taking an equal chance of being anyone.
• Rawls's thick veil removes knowledge of everyone's desires and conceptions of the good. Its function is to prevent the principles of justice from being biased by the existing, and potentially unjust, state of affairs. As the SEP article notes, if people's preferences are shaped by discriminatory institutions, a thin veil would simply bake those prejudices into the principles of justice. The thick veil forces a more fundamental evaluation from a standpoint detached from the status quo.

3. The Parties: Modeling Rational Choice

Now that we have the setting (the OP) and the informational constraints (the VoI), we need to specify the agents within our model. How do the parties behind the veil reason? Rawls makes two key assumptions about them.

1. Rationality: The parties are rational in the standard economic sense. They choose the most effective means to advance their ends.
2. Mutual Disinterest: The parties are not interested in helping or harming one another. They are simply trying to get the best possible outcome for themselves. This is a modeling assumption to prevent the choice from becoming indeterminate. It's not that Rawls thinks people are selfish; rather, he models impartiality through the Veil of Ignorance, not by assuming altruism.

But if they don't know their conception of the good, what ends are they trying to advance? Rawls's solution is the concept of primary social goods. These are all-purpose goods that are useful for pursuing any rational plan of life. The primary goods are:

• Rights and liberties
• Powers and opportunities
• Income and wealth
• The social bases of self-respect

The parties' goal in the Original Position is to choose principles that will secure for them the best possible share of these primary goods once the veil is lifted. This gives them a clear, rational basis for making a decision.

As the article explains, the parties are also motivated by "higher-order interests" in developing their two "moral powers": the capacity for a sense of justice and the capacity for a conception of the good. This means they want to choose a society where they can be rational, moral, and cooperative agents.

4. The Function in Practice: Choosing Principles

So, how does this whole apparatus—the OP, the VoI, and the rational parties—actually function to select principles of justice? The parties must make a choice under conditions of profound uncertainty. Given your background in statistics and decision theory, you'll recognize this as a classic problem.

Rawls argues that in this unique situation, the rational decision rule is maximin (maximizing the minimum). This means you evaluate each possible set of principles by looking at the worst possible outcome (the position of the least-advantaged person) and choose the principles that make that worst-off position as good as it can be. You choose as if your worst enemy will assign you your place in society.

Why maximin? Rawls argues it's rational because:

1. The stakes are incredibly high: The choice determines the basic structure of your life and is irrevocable. You can't risk an intolerable outcome (like being a slave) for the chance of a slightly better outcome.
2. No basis for probabilities: The thick Veil of Ignorance means you can't calculate the probability of ending up in any given position.
3. The maximin choice is acceptable: The principles Rawls proposes guarantee a satisfactory minimum of rights, liberties, and resources, making gains above that minimum less critical.

Let's see how this decision rule functions to eliminate competing theories like utilitarianism.

The key function here is that the entire setup acts as an argumentative filter. You feed different candidate principles into the Original Position, and the combination of the Veil of Ignorance and the maximin rule filters out those that would be an irrational gamble from an impartial perspective. Utilitarianism is rejected because it could lead to the oppression of minorities for the greater good. Laissez-faire libertarianism is rejected because it allows morally arbitrary factors (like the family you're born into) to have an overwhelming effect on life chances.

Conclusion

We have dissected the Original Position and the Veil of Ignorance, revealing them to be not just a philosophical story but a structured analytical model. Its function is to translate a general intuition—that justice should be impartial—into a formal procedure for choosing and justifying principles.

Key Takeaways:

• The Original Position functions as a hypothetical, fair choice scenario designed to ensure procedural justice.
• The Veil of Ignorance is the core mechanism that enforces impartiality by filtering out knowledge of morally arbitrary facts about oneself and society. Rawls's "thick" veil is specifically designed to prevent principles from being biased by existing preferences or an unjust status quo.
• The parties are modeled as rational, mutually disinterested agents whose objective is to maximize their share of primary social goods, providing a basis for choice without knowing their specific life plan.
• The rational choice strategy in this unique context is maximin, which functions to select principles that protect the worst-off position in society, thus filtering out principles like utilitarianism that would risk sacrificing the few for the many.

Together, these components create a powerful machine for reasoning about justice—one that aims to generate principles that any free and equal rational person could endorse.

Preview of the next lesson:

Now that we have analyzed the intricate machinery of the Original Position, we are ready to examine its output. In our next lesson, we will turn to the two principles of justice that Rawls argues would be unanimously chosen from behind the veil. We will pay special attention to the justification for the second principle, the famous and controversial Difference Principle.
