Introduction
Welcome to your next lesson on classical conceptions of justice. In our previous session, we delved into Plato's highly influential theory from The Republic, where justice was presented as a form of harmony—an ideal ordering of the tripartite soul and, by analogy, the tripartite state. For Plato, justice is a kind of psychic and political health, achieved when reason rules and all parts perform their natural function.
Today, we turn to Plato's most brilliant student, Aristotle. While he shares Plato's view that justice is connected to virtue and the good life, his method is starkly different. Instead of designing an ideal state from abstract principles, Aristotle's approach is more empirical and practical. He examines justice as it functions within existing political communities (poleis). This shift brings the concept of justice "down to earth."
This lesson will focus on a distinction that Aristotle originated and which has profoundly shaped Western legal and political thought for over two millennia. Our goal is to describe Aristotle's conception of justice, distinguishing between distributive justice (proportional to merit) and corrective justice. You'll find his use of mathematical proportion to define these concepts particularly precise.
1. From Complete Virtue to Particular Justice
Aristotle begins Book V of his Nicomachean Ethics by noting that "justice" is used in two main senses.
-
General Justice: In its broadest sense, justice is "complete virtue... in relation to our neighbour." It is the whole of virtue, considered from the perspective of social interaction. A person who is courageous, temperate, and wise will also act justly towards others. In this sense, justice is synonymous with lawfulness, as the law (ideally) commands virtuous action for the good of the community.
-
Particular Justice: This is justice as a part of virtue, specifically concerned with fairness and avoiding pleonexia—the vice of grasping for more than one's fair share of goods (or less than one's fair share of burdens).
To help clarify this distinction, let's turn to a video lecture that unpacks the opening of Aristotle's analysis.
Aristotle's "Nicomachean Ethics" Book V - Justice
The following video, 'Aristotle's "Nicomachean Ethics" Book V - Justice' from the channel Mark Thorsby, provides a clear, university-level walkthrough of Aristotle's initial moves. It will help us separate the broad idea of justice-as-virtue from the specific forms of justice we'll be focusing on.
About a minute in, please watch Aristotle's justice concepts. As you watch, focus on: How Aristotle initially defines justice as a 'state' of character (the disposition to do just things). The distinction between general justice (complete excellence) and particular justice (a part of excellence). The example of the two adulterers (one who gains, one who acts from passion) used to isolate the vice of injustice as unfairness/gain.
This distinction is crucial. While general justice is an all-encompassing moral concept, particular justice is where the architectural work of a political system happens. It's about the rules for carving up resources and righting wrongs. It is this particular justice that Aristotle divides into our two main types: distributive and corrective.
2. Distributive Justice: Proportionality and Merit
The first form of particular justice is distributive justice (dianometikon dikaion). It concerns the allocation of common goods that can be divided among the members of a political community—things like honor, public office, and wealth.
The core principle here is not simple equality, but proportional equality. The just distribution is one that is made "according to merit" (kat' axian). Aristotle's insight, which resonates with your background in mathematics, is that this is a question of geometrical proportion.
The just distribution requires four terms: two persons and two shares. The ratio of the shares must be equal to the ratio of the merits of the persons receiving them.
If Person A's merit is to Person B's merit as a value of x is to a value of y, then a just distribution gives Share C (with value x') to Person A and Share D (with value y') to Person B, such that:
An unjust distribution is one that violates this proportion.
Of course, this raises the immediate question: what is the correct standard of merit? Aristotle observes that this is a deeply political question, and different regimes have different answers:
- Democracies: Merit is defined by free birth. All citizens are considered equal and thus deserve equal shares.
- Oligarchies: Merit is defined by wealth. The rich have a greater claim on honors and offices.
- Aristocracies: Merit is defined by virtue or excellence (aretē). The best people should rule and receive the greatest honors.
To see how Aristotle lays this out in his own words, let's turn to the primary text.
We will now read the relevant section from Aristotle's 'Nicomachean Ethics' itself. This passage from Book V clearly lays out the concept of distributive justice and its reliance on geometrical proportion.
Please read Section III, starting from 'The unjust man [in this limited sense of the word], we say, is unfair...' and ending with 'This then is one form of that which is just.' Focus on how Aristotle builds the argument for proportional distribution and connects different standards of merit to different political systems.
Test your understanding!
Imagine a tech startup is allocating its yearly bonus pool. The founders are debating the principle of distribution.
- Founder 1 argues for an equal bonus for every employee, from the junior developer to the CTO.
- Founder 2 argues the bonus should be proportional to the amount of capital each employee has invested in the company.
- Founder 3 argues the bonus should be proportional to each employee's performance review scores and contribution to product development in the past year.
How would Aristotle categorize the principle of "merit" being used by each founder, and to which political regime would each correspond?
Show answer
- Founder 1 is using a democratic standard of merit. The principle is simple equality among all members of the community (the company). Every employee is treated as equal and thus deserving of an equal share.
- Founder 2 is using an oligarchic standard of merit. The principle is that distributions should be based on wealth or capital. This is analogous to an oligarchy where political power and rewards are proportional to wealth.
- Founder 3 is using an aristocratic standard of merit. The principle is that distributions should be based on excellence or virtue (in this case, job performance and contribution). This aligns with Aristotle's ideal of aristocracy, where the "best" people receive the greatest rewards.
3. Corrective Justice: Arithmetic Restoration
The second form of particular justice is corrective justice (diorthotikon dikaion), also known as rectificatory or remedial justice. This type of justice does not concern the distribution of common goods, but rather the righting of wrongs that arise in transactions between individuals.
These transactions can be:
- Voluntary: Contracts, sales, loans, etc. A wrong occurs here with a breach of the agreement.
- Involuntary: Theft, assault, murder, etc. A wrong occurs here through force or fraud.
The principle of corrective justice is fundamentally different from that of distributive justice. Here, the law looks only at the "character of the injury" and treats the parties as equal. It doesn't matter if a good person defrauds a bad person, or a wealthy person assaults a poor one. Their relative merit or social standing is irrelevant.
Corrective justice operates according to an arithmetical proportion. Injustice is an inequality where one party has a "gain" and the other a "loss." The role of the judge is to restore the equality that existed before the wrong occurred. The judge finds the arithmetic mean between the gain and the loss by imposing a penalty that takes away the perpetrator's gain and compensates the victim's loss.
Imagine a line representing a person's assets. A theft occurs, reducing the victim's assets and increasing the thief's. The judge's task is to take the amount of the theft from the thief and return it to the victim, restoring both to their original state. The judge acts as a "mediator" who re-establishes the middle point.
Aristotle's "Nicomachean Ethics" Book V - Justice
Let's return to the Thorsby video to see how corrective justice is explained. Pay close attention to how the speaker contrasts this with distributive justice and explains the role of the judge.
Starting around 15 minutes in, please watch corrective justice. Focus on: The goal of rectifying the 'breach of proportionate equality.' Why Aristotle uses the term 'rectificatory' rather than 'retributive.' The role of the judge as an 'intermediate' who restores equality arithmetically.
To solidify this, let's read Aristotle's own account.
The following section from the 'Nicomachean Ethics' details corrective justice, making the crucial distinction between arithmetical and geometrical proportion.
Please read Section IV on corrective justice, starting from 'It remains to treat of the other form...' and continuing to the end of the section. Notice how Aristotle stresses that in this context, 'the law looks only to the difference created by the injury, treating the parties themselves as equal.'
This distinction has had a monumental impact. The principles of corrective justice form the foundation of modern private law, such as contract law and tort law, where the goal is typically to compensate for loss and restore the injured party to their prior position, rather than to redistribute wealth according to some notion of social merit.
This document excerpt from a legal analysis provides a concise summary of Aristotle's foundational distinction. It clearly separates distributive justice, which involves proportionate sharing of benefits and burdens, from corrective justice, which focuses on rectifying private wrongs and restoring equality.

Conclusion
In this lesson, we have moved from Plato's holistic vision to Aristotle's analytical breakdown of justice. By parsing justice into its component parts, Aristotle provided an enduring framework for analyzing the fairness of social institutions.
Key Takeaways:
- Aristotle distinguishes general justice (lawfulness, complete virtue) from particular justice (fairness in specific spheres).
- Distributive justice governs the allocation of common goods. Its principle is proportional equality based on a politically defined standard of merit, following a geometrical proportion.
- Corrective justice governs the rectification of wrongs in private transactions. Its principle is the restoration of equality, treating the parties as formally equal and following an arithmetical proportion.
- The judge's role in corrective justice is to act as an intermediary, removing the "gain" from the wrongdoer and restoring the "loss" to the victim.
This framework moves us away from designing a single perfect society and toward identifying the distinct principles that must operate in different domains of a political community—one for distribution and another for rectification.
Preview of the next lesson:
We will continue our exploration of "natural justice" by examining natural law theory. This school of thought, heavily influenced by Aristotle's idea of a telos (natural purpose or end), posits that justice is not merely a social convention but is derived from reason and the fundamental nature of humanity itself. This will lay the groundwork for our later analysis of John Locke's theory of natural rights.
