IB Philosophy 7.2.3 Interrelationships Between Justice, Freedom and Equality Notes

The Conceptual Triangle: Justice, Freedom and Equality

1. Justice, freedom, and equality are the three foundational values of modern political philosophy. Each appears intuitively desirable, yet the precise relationship between them is one of the most contested questions in the discipline.
   1. As explored in 7.2.1, theories of social justice differ sharply on how to balance these ideals.
2. The overarching question for Unit 7 asks whether freedom and equality are compatible. Some traditions treat them as mutually reinforcing: genuine freedom requires a baseline of equality, and genuine equality requires protections for individual liberty.
   1. Other traditions insist that the three values are in irreducible tension (meaning the conflict between them cannot be resolved, you must always choose one at the expense of another), so that advancing one value necessarily constrains another.
3. Freedom in political philosophy typically refers to the absence of external constraints on action (negative liberty) or the presence of conditions that enable individuals to pursue their goals (positive liberty). These two conceptions, explored further in 7.3.2, generate very different implications for the relationship between freedom and equality.
4. Equality is equally complex. Formal equality demands identical treatment under the law, while substantive equality demands that material conditions be adjusted so that individuals have genuinely comparable opportunities.
   1. A society might achieve formal equality while tolerating vast disparities in wealth, health, and education.

Competing Traditions on the Priority of Values

1. Justice acts as the balancing concept between freedom and equality. When we ask whether a political arrangement is just, we are really asking: does this arrangement give people the right mix of freedom and equality, in a way that can be morally defended? Justice sets the terms on which freedom and equality can coexist.
   1. Different theories of justice assign different weights to freedom and equality, yielding radically different visions of the good society.
2. The liberal tradition, from John Locke’s Second Treatise through John Stuart Mill’s On Liberty, treats individual freedom as the prerequisite for human flourishing. Locke argued that natural rights to life, liberty, and property set limits on what any government may do in the name of equality.
   1. Mill defended freedom of thought and expression as essential to social progress, arguing that societies that suppress individual liberty stagnate. On this view, equality matters primarily as a condition for the exercise of freedom, not as an independent value that might override it.
3. The socialist tradition reverses this priority. Karl Marx argued that the formal freedoms celebrated by liberalism are illusory so long as economic inequality persists: a starving person’s right to vote is meaningless when material conditions prevent genuine choice.
4. Contemporary egalitarians such as G.A. Cohen extend this critique, arguing that a just society requires not only fair institutions but a culture of equality in which individuals voluntarily limit their pursuit of personal advantage. On this view, freedom without equality is a privilege of the wealthy, not a universal condition.
5. Classical utilitarianism, from Jeremy Bentham through John Stuart Mill, sidesteps the tension by treating both freedom and equality as tools: they matter only to the extent that they produce the most total happiness across society (aggregate welfare). The just arrangement is simply whichever one maximises overall well-being.
   1. But this flexibility comes at a cost: utilitarianism can justify restricting the freedom of a minority if doing so produces a net gain for the majority (as discussed in 7.2.2).
6. The philosophical challenge is to work out whether any coherent ranking of these values is possible, can we always say which one comes first? or whether politics is inevitably a matter of painful trade-offs between things we genuinely cannot all have at once.

Rawls and the Reconciliation of Justice with Freedom and Equality

1. John Rawls’s justice as fairness, introduced in 7.2.1, provides the most influential modern attempt to reconcile freedom and equality within a single theory of justice.
   1. From this position, Rawls argues that rational agents would select two principles. The first principle guarantees each person an equal right to the most extensive system of basic liberties compatible with a similar system for all.
   2. This principle has lexical priority (meaning it comes first in an ordered list, like letters in a dictionary: you must satisfy it fully before moving on to the next): basic liberties such as speech, conscience, and political participation cannot be traded away, even for significant economic gains.
