The Concept of Justice

Saurav Gupta introduces justice as an ideal in social and political philosophy, following earlier lessons on equality and liberty. The lecture covers the general meaning and types of justice, major philosophers’ theories, and questions from previous UPSC Philosophy Optional exams.

Meaning and changing nature of justice

Justice is broadly associated with fairness, righteousness, and reasonableness. It requires that people not be treated unfairly, arbitrarily, or with bias. Injustice, by contrast, involves unreasonable or discriminatory treatment.

Justice is a dynamic idea: its meaning and standards can change across societies and historical periods. Practices such as slavery, untouchability, and gender or racial discrimination were once accepted in some societies but are now widely regarded as unjust. The lecturer links this evolution to changing public opinion and growing support for liberty and equality.

Types of justice

• Distributive justice: Resources and opportunities should be allocated fairly among individuals and groups, without discrimination based on characteristics such as race, religion, sex, or orientation.
• Environmental justice: Marginalized communities should have fair access to environmental benefits and should share environmental burdens equitably.
• Social justice: All members of society should have equal rights and opportunities, as well as access to what they need.
• Legal justice: Laws should be applied impartially, and trials should be fair.
• Political justice: Citizens should have fair opportunities to participate in government, including voting and standing for office.
• Economic justice: Economic opportunities and resources should be distributed fairly, and extreme disparities reduced. The lecture connects this concern to Karl Marx, who argues that economic inequality divides society into classes, including capitalists and workers.

Plato’s theory of justice

Plato compares society to a well-functioning body. Just as a body works well when its parts perform their proper functions, society works well when its members fulfil their roles.

He divides society into three groups:

• Rulers: Guided by reason and wisdom; philosophers are suited to govern.
• Auxiliaries or soldiers: Protect society.
• Workers or producers: Perform productive and economic work.

Justice is achieved when each group performs its designated role and society functions harmoniously. This role-based division has been criticized for resembling a fixed social hierarchy, including comparisons with caste-based arrangements.

Aristotle’s three forms of justice

Aristotle’s account emphasizes fair treatment according to relevant differences, rather than giving everyone identical treatment.

• Distributive justice: Resources should be distributed according to relevant considerations such as need, merit, or contribution. Treating everyone identically may be unfair when their needs or capacities differ.
• Retributive justice: Punishment should be proportionate to the harm or offence. The lecture illustrates this with the idea that the response should correspond to the loss caused.
• Commutative justice (called “communicative justice” in the subtitles): Transactions and agreements should be fair, and parties should honour their commitments. For example, an online purchase is unjust if the delivered item materially differs from what was described.

Amartya Sen’s view

Sen’s approach focuses on enabling people to live valuable and fulfilling lives. Justice requires removing social, economic, and political barriers that prevent people from developing their capabilities and making meaningful choices.

Governments should help ensure access to essentials such as education, health care, and accessible infrastructure. Justice does not mean uniform treatment: people may need different forms or levels of support to achieve real opportunities.

The lecturer presents Sen’s view as extending Rawls’s fairness-based account by focusing more directly on people’s lives, capabilities, and the removal of obstacles.

John Rawls: Justice as fairness

Rawls’s idea of justice is explained through the veil of ignorance. When designing society’s rules, people should imagine that they do not know what position they themselves will occupy.

The lecturer illustrates this with cutting a pizza or cake into portions: someone who does not know which portion they will receive has an incentive to make the portions equal. Applied to society, this device encourages rules that people would regard as fair regardless of their eventual position.

The lecture also says that inequalities should be structured to benefit the least advantaged.

Exam point: To explain “justice as fairness,” describe the veil of ignorance and show how it encourages impartial rules.

Robert Nozick’s theory

Nozick emphasizes individual liberty and property rights. People are entitled to property acquired through just means, without force or fraud.

If someone gains wealth through their effort or voluntary exchanges, the state should not automatically require them to transfer it to others to produce equality. People may share their wealth voluntarily, but the lecture says Nozick opposes government-enforced redistribution, including progressive taxation.

The lecture’s example contrasts a person who invests and earns income with someone who does not invest: on this account, the first person is not automatically responsible for giving their earnings to the second.

Criticism: This approach may allow inequality to grow and provide too little support for disadvantaged people.

Previous-year questions and exam guidance

The lecturer discusses three past-paper themes:

• 2023, 10 marks: Explain Rawls’s “justice as fairness,” especially the veil of ignorance.
• 2021, 20 marks (as identified in the subtitles): Discuss how Amartya Sen’s conception of justice improves upon Rawls’s. The suggested comparison is Rawls’s focus on fair principles versus Sen’s focus on capabilities, valuable lives, and removing barriers.
• 2021, 10 marks: Critically discuss Nozick’s distributive theory. Explain property rights and voluntary exchange, then assess the criticism that his view can deepen inequality and neglect disadvantaged groups.

The lecturer encourages students to use examples from class, explain each theory clearly, and include criticism when a question asks for a critical discussion. The final task is to write a short answer to the Nozick question in the comments.
