Quotes About This Concept
“Among the essential features of this situation is that no 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. The principles of justice are chosen behind a veil of ignorance.”
“Justice is the first virtue of social institutions, as truth is of systems of thought. A theory however elegant and economical must be rejected or revised if it is untrue; likewise laws and institutions no matter how efficient and well-arranged must be reformed or abolished if they are unjust.”

“I do not wish women to have power over men; but over themselves.”

“Society is indeed a contract... It is a partnership in all science; a partnership in all art; a partnership in every virtue and in all perfection. As the ends of such a partnership cannot be obtained in many generations, it becomes a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born.”
“Society is indeed a contract... but the state ought not to be considered as nothing better than a partnership agreement in a trade of pepper and coffee... It is a partnership in all science; a partnership in all art; a partnership in every virtue and in all perfection.”
“After the Egyptian and Indian, the Greek and Roman, the Teuton and Mongolian, the Negro is a sort of seventh son, born with a veil, and gifted with second-sight in this American world, — a world which yields him no true self-consciousness, but only lets him see himself through the revelation of the other world. It is a peculiar sensation, this double-consciousness, this sense of always looking at one's self through the eyes of others, of measuring one's soul by the tape of a world that looks on in amused contempt and pity.”
“National liberation, national renaissance, the restoration of nationhood to the people, commonwealth: whatever the name used, decolonization is always a violent phenomenon.”

The actors seek to reach an understanding about the action situation and their plans of action in order to coordinate their actions by way of agreement.”

“The tyranny of the majority is now generally included among the evils against which society requires to be on its guard. Like other tyrannies, the tyranny of the majority was at first, and is still vulgarly, held in dread, chiefly as operating through the acts of the public authorities. But reflecting persons perceived that when society is itself the tyrant — society collectively, over the separate individuals who compose it — its means of tyrannizing are not restricted to the acts which it may do through the hands of its political functionaries.”
“The tyranny of the majority is now generally included among the evils against which society requires to be on its guard.”

“Natural rights is simple nonsense: natural and imprescriptible rights, rhetorical nonsense, nonsense upon stilts.”
“True law is right reason in agreement with nature; it is of universal application, unchanging and everlasting; it summons to duty by its commands and averts from wrongdoing by its prohibitions.”
“The commonwealth is the property of the people: the people is the multitude bound together by the agreement on what is right and the community of interest — and the republic that has lost the justice has lost the name.”
“Though the earth, and all inferior creatures, be common to all men, yet every man has a property in his own person: this no body has any right to but himself. The labour of his body, and the work of his hands, we may say, are properly his. Whatsoever then he removes out of the state that nature hath provided, and left it in, he hath mixed his labour with, and joined to it something that is his own, and thereby makes it his property.”
“Act always for the common good: what benefits the hive benefits the bee, and the person who serves the whole is served by the whole.”

“From each according to his ability, to each according to his needs.”
“The care of souls cannot belong to the civil magistrate, because his power consists only in outward force; but true and saving religion consists in the inward persuasion of the mind.”

“Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do.”
“In such condition there is no place for industry, because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving, and removing, such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.”
“Man is born free, and everywhere he is in chains. Many a man believes himself to be the master of others who is, no less than they, a slave. How did this change come about? I do not know. What can make it legitimate? I believe I can answer that question.”
“Man is by nature a political animal, and a man who is by nature and not merely by fortune citiless is either superior or inferior to man.”
Definition
Justice is a central ethical and political idea, but it does not have one settled meaning. It can concern how a person treats another person, how benefits and burdens are shared, whether institutions are fair, and whether laws or policies can be justified. A minimal formulation is that justice asks what is due to people and how those claims should shape action.
This breadth is important. Justice is not simply obedience to whatever law exists, nor is it identical with private kindness. A law may be unjust, and a well-intentioned act may still overlook another person's claim. Philosophical accounts therefore ask how to connect character, social practices, and institutions without assuming that one formula resolves every case.
Historical Origins
Questions about what people owe one another are older than Greek philosophy. In the Greek tradition, however, justice became a sustained object of argument about the soul, the city, education, distribution, law, and the good life. Plato and Aristotle made these questions central to ethical inquiry while developing different accounts of their scope.
Ancient categories should not be treated as ready-made answers to modern debates. Greek societies were marked by exclusions involving citizenship, gender, status, and enslavement. Their arguments can still illuminate questions about character and shared life, but responsible interpretation also asks whose experience and standing those arguments left out.
Justice in Greek Philosophy
Greek philosophy often joins justice to the question of how a human life goes well. Socratic inquiry tests confident assumptions about virtue and obligation. Plato explores whether justice orders both a person and a community. Aristotle examines justice as a virtue exercised with and toward others, as well as in the distribution and correction of social goods.
These approaches resist a narrow picture of justice as punishment alone. They ask about education, habits of character, political arrangements, friendship, and the uses of power. They also disagree about important matters. Plato's ideal city and Aristotle's more differentiated account of distributive and corrective justice should not be collapsed into a single Greek doctrine.
Plato's View of Justice
In the Republic, Plato frames justice through the question of whether it is better to be just than unjust. The dialogue examines a city in speech partly to make the structure of justice visible on a larger scale. In the best-known account, justice involves each part of the city and each part of the soul performing its appropriate work under the guidance of reason.
This is not merely a theory of legal compliance. Plato links justice to education, knowledge, desire, and the ordering of a person's life. The account remains controversial: its political proposals, hierarchy, and use of social roles raise serious objections. Its enduring value lies in making justice a question about the formation of character and the conditions under which power can be responsibly exercised, not only a question about rules after harm has occurred.
Aristotle's View of Justice
Aristotle gives justice sustained attention in Book V of the Nicomachean Ethics. He distinguishes a broad sense of justice, connected with complete virtue in relation to others, from more particular forms concerned with fair distribution and the correction of wrongs. This distinction helps explain why justice can name both a general ethical orientation and more specific questions about allocation, exchange, and remedy.
Aristotle's account also emphasizes proportionality. Equal treatment is not always identical treatment; what is fair may depend on the goods at stake, the relevant similarities among people, and the purposes of a practice. These claims require careful scrutiny today, especially because ancient accounts of status and merit can preserve unjust assumptions. Still, the distinction between distributive and corrective concerns remains influential in later philosophical and legal thought.
Justice and the Good Life
Justice belongs to the good life because flourishing is not only a private achievement. A person acts among others, receives benefits and burdens through institutions, and participates in relationships that can be fair or exploitative. Greek virtue ethics therefore treats justice as a social virtue: it concerns how character is expressed where another person's good is at stake.
This does not mean that a good life can be measured by moral purity alone. Health, security, friendship, education, and material conditions affect what people can do. The point is instead that a conception of flourishing which ignores responsibility, exclusion, or unfair advantage is incomplete. Justice asks readers to connect personal aims with the shared conditions that make human lives possible.
Justice and Practical Wisdom
Practical Wisdom is essential because justice cannot be reduced to repeating a general phrase. Judging a situation may require attention to evidence, roles, harms, power differences, competing claims, and the limits of one's knowledge. Good judgment does not excuse bias; it is disciplined by reasons, by openness to correction, and by the recognition that others can challenge one's view of what is fair.
Justice also clarifies the role of Courage. Acting fairly can involve risk: resisting a harmful practice, acknowledging an advantage, or speaking honestly when silence is easier. Courage without justice can become mere boldness; justice without courage can remain an unacted conviction. Their relation is one reason virtues are better understood as mutually shaping capacities than as isolated traits.
Justice Today
Contemporary debates about justice include rights, democratic institutions, discrimination, economic inequality, criminal law, climate responsibility, and recognition. Ancient Greek texts do not settle these questions. They can, however, sharpen them by asking what reasons can justify an arrangement, whether a practice treats people as participants in shared life, and what kinds of character and institutions make fair action more likely.
The practical task is neither to apply antiquity mechanically nor to treat justice as a personal feeling. It is to examine concrete arrangements, seek reliable information, listen to those affected, and remain willing to revise a judgment. Justice is demanding precisely because it joins reflection with action toward others.
