In John Rawls’s A Theory of Justice, the balance between individual rights and the common good is a fundamental aspect of his conception of justice as fairness. Rawls argues that a just society must protect the basic liberties of individuals while also promoting the welfare of all its members, particularly the least advantaged. This balance is crucial to ensuring that justice is both fair and practical, allowing for a harmonious and stable society in which individuals can pursue their own goals within a framework that supports the collective well-being.
Rawls argues that the equal liberty principle and the difference principle, which provide a framework for bestowing individual rights, are essential to respecting the moral worth of individuals, as they allow people to pursue their own conception of the good life, or eudaimonia. Like Aristotle, Rawls believes that happiness is achieved not through the pursuit of wealth or pleasure but through cultivating virtues such as fairness, free expression, and moral integrity. Individual rights allow people to pursue these virtues. This reflects Rawls’s commitment to liberal democracy, where the protection of personal freedoms is a cornerstone of society.
However, Rawls recognizes that a just society must promote the common good, particularly through the difference principle. This principle permits social and economic inequalities only if they benefit the least advantaged members of society. While some individuals may accumulate more wealth or power than others in a just society, the difference principle provides a corrective measure to redistribute some of society’s resources to those who are worse off. This concept reflects Rawls’s belief that justice requires not only the protection of individual rights but also the promotion of social and economic conditions that allow everyone to flourish.
The greatest challenge in Rawls’s theory is balancing individual rights and the common good so that neither is unduly sacrificed. This is theoretically possible in a just society built from individuals in the original position, but in real-world societies that already contain longstanding inequalities, this balance is difficult to achieve. Even for Rawls, the liberty principle takes priority over the difference principle, skewing society’s protection of liberties in favor of individual rights. A key aspect of this concept is that basic liberties cannot be compromised for the sake of economic or social advantages. This prioritization ensures that individual rights are safeguarded against potential abuses that might arise from the pursuit of collective goals, such as those of political, professional, or financial institutions.
Social consensus plays a critical role in establishing and sustaining a just society. Rawls’s theory of justice as fairness states that a well-ordered society requires a shared understanding of justice among its members. This shared understanding, or social consensus, is not only necessary for the legitimacy of the principles of justice but also for their effective implementation. Without social consensus, the principles of justice could not be consistently upheld, leading to social instability and injustice.
For Rawls’s theory to work, everyone must accept and understand that others accept and understand the same principles of justice. This shared agreement forms the foundation for cooperation among citizens, as it ensures that all individuals are committed to maintaining the principles of justice in their social, professional, and political interactions. However, Rawls recognizes that achieving social consensus in a pluralistic society, where individuals have diverse and often conflicting moral, religious, and philosophical views, is a significant challenge. To address this, Rawls introduces the concept of “overlapping consensus.” Overlapping consensus occurs when individuals with different comprehensive doctrines—such as religious or political beliefs—agree on the same principles of justice for different reasons. While they may not share the same underlying reasons for endorsing justice as fairness, theoretically, they recognize their value in structuring a fair and orderly society.
The concept of overlapping consensus is perhaps the most difficult to apply in practice because religious, ethical, and political differences are not easily overcome. In a society created by individuals in the original position, which is entirely fair to members at all levels of society, achieving social consensus is not difficult. But in real-world societies that are built on principles of inequality that benefit the most powerful while exploiting those who are most vulnerable, overlapping consensus on the concept of justice as fairness is difficult to achieve. While it is crucial because it allows for the principles of justice to be supported by a wide range of citizens, regardless of their individual beliefs, in practice, there is little incentive for those with power and privilege to share it if they believe it will disadvantage them. Without social consensus, the principles of justice as fairness could be seen as imposed or arbitrary, leading to resistance and conflict. Only true consensus, therefore, provides the necessary foundation for a just society by ensuring that the principles of justice are genuinely accepted and integrated into the fabric of social life.
In A Theory of Justice, institutions play a crucial role in maintaining fairness and ensuring that the principles of justice operate effectively in society. This is because, under the concept of justice as fairness, a just society is one where institutions reflect the principles that rational individuals would agree to under fair conditions. These institutions include laws, social norms, economic arrangements, and political systems that together determine how benefits and burdens are distributed among members of society.
In Rawls’s theory, the ideas about how to govern a just society that come from individuals in the original position are not just hypothetical: They must be practically implemented in the institutions that structure the society. This ensures that the principles chosen are fair to all, especially to the least advantaged members of society. Throughout the text, Rawls stresses that without just institutions, the abstract principles of justice lack real-world applicability and fail to achieve their intended outcomes.
The two key principles of society—the equal liberty principle and the difference principle—both require institutions to play a role in maintaining fairness. For instance, the equal liberty principle requires legal and political institutions to protect individual rights and freedoms, ensuring that no group is unjustly disadvantaged. The difference principle requires economic institutions to structure inequalities in a way that benefits those who are least advantaged, such as taxing higher-income earners more and creating welfare programs. In this case, the inequalities experienced by the wealthy are designed to have little negative impact on their well-being, while programs benefiting those in the lowest socioeconomic brackets are designed to increase their well-being in the spirit of fairness.
For this reason, institutions are vital in ensuring that opportunities are distributed fairly. Institutions must ensure that individuals have effective access to opportunities regardless of their social background. Educational institutions, for example, must provide access to quality education, enabling all individuals to compete fairly for positions of advantage. Without such institutions, social mobility would be stunted, and the promise of justice as fairness would remain unfulfilled.
Rawls acknowledges that society is characterized by a diversity of views and interests and that, in a just society, institutions provide a framework for resolving conflicts and making collective decisions in a fair and equitable manner. Democratic institutions, such as voting and a free press, are essential in ensuring that all voices are heard and that policies reflect society’s shared values.
