Social and Political Philosophy: Western

Overview

The unit has a narrative arc that helps revision. It begins with Plato, who distrusts democracy because he thinks most people lack knowledge of the good, and who designs a city ruled by philosophers. It moves to contract theory, which replaces knowledge with consent as the ground of legitimacy, but disagrees about what consent creates: an absolute sovereign in Hobbes, a limited government protecting natural rights in Locke, or a general will expressing the common good in Rousseau. Liberalism then refines contract into rights and liberties that no consent can alienate, and Mill harm principle draws the boundary of state interference. Justice theory asks what liberalism must distribute and why: Rawls answers with fairness behind a veil of ignorance, Nozick answers with historical entitlement and rejects patterned distribution, and communitarians answer that justice depends on the shared meanings of a community. The critics then step back: Marx says liberal justice legitimates class domination, communitarians say it presupposes an unencumbered self that does not exist, multiculturalists say it treats cultural membership as irrelevant when it is central to identity, and feminists say it ignores the family and gendered labour that make public liberty possible. Each critique is also a test: a liberal theory that cannot answer Marx on material power, the communitarian on belonging, the multiculturalist on recognition, or the feminist on gender is incomplete, and a critique that cannot explain why individuals should be protected against their community is also incomplete. Hold both sides of that test and most questions answer themselves.

Plato and social contract theory

Plato Republic asks what justice is by asking what a just city is. The city is divided into three classes mirroring the three parts of the soul: producers driven by appetite, auxiliaries animated by spirit, and guardians ruled by reason, with philosopher-kings at the head because they alone know the Form of the Good. Justice is each part doing its own work without meddling: the shoemaker makes shoes, the soldier defends, the philosopher rules, and harmony results. Plato distrusts democracy because he thinks it confuses freedom with licence, letting appetite rule, and he distrusts oligarchy and tyranny for the same reason in different forms: each degenerate regime is a soul disordered. His proposals, communal property and family life for guardians, equality of education for women guardians, and censorship of poetry that corrupts the soul, follow from the aim of unity: guardians must have no private interest competing with the common good. Aristotle criticised Plato unity as excessive: a city is not a single organism but a plurality of households and citizens, and abolishing the family destroys the very affections that make community possible. Social contract theory replaces Plato knowledge with agreement as legitimacy. Hobbes state of nature is a war of all against all, where life is solitary, poor, nasty, brutish, and short, because roughly equal, fearful, glory-seeking persons compete for scarce goods without a common power. Reason dictates laws of nature, above all to seek peace, and persons covenant to surrender their right to all things to an absolute sovereign, the Leviathan, who alone can keep peace. The sovereign is not party to the contract and cannot be deposed for breaking it, because any right of rebellion returns society to war. Locke state of nature is different: it is a state of liberty under natural law, where persons own themselves and the fruits of their labour, but it lacks an impartial judge, so insecurity and partiality lead to a contract creating government as a trust to protect life, liberty, and property. Government that violates that trust, by arbitrary taxation or absolute rule, may be resisted, and the right of revolution is the ultimate check. Rousseau state of nature is the most radical: natural humans are solitary, compassionate, and free, and inequality arises with property, agriculture, and civilisation, which create dependence and domination. The social contract must therefore recover freedom in society through the general will: each person alienates all rights to the whole community, obeys only laws they have prescribed to themselves, and remains free because the sovereign is the people themselves, not a separate ruler. The general will is not the will of all, the sum of private interests, but the common interest, and a citizen who disobeys it may be forced to be free, a phrase that has troubled liberals ever since. The three contracts thus offer three sovereigns: Hobbes absolute monarch, Locke limited government as trust, Rousseau the people as general will, and the choice between them is a choice about what freedom means.

Liberty and equality

Liberty is the most contested concept in political philosophy, and the first distinction to master is Isaiah Berlin two concepts. Negative liberty is freedom from interference: a person is free to the extent no one prevents them from acting. Positive liberty is freedom to be one own master: a person is free to the extent they realise their rational self, not merely act without obstruction. Berlin warned that positive liberty can be abused: if a ruler claims to know a person true self better than the person does, coercion can be presented as liberation, forcing people to be free in Rousseau sense. Liberals therefore tend to defend negative liberty as a safer concept, while critics reply that negative liberty without resources is empty: a person legally free to buy bread but without money is not meaningfully free, so positive liberty captures the material conditions of real freedom. Mill harm principle offers a liberal boundary: the state may interfere with an individual only to prevent harm to others, not for the individual own good or for moral disapproval. This protects experiments in living, the diverse ways of life through which humanity discovers better ways, and it grounds free speech on the ground that even false opinions may contain part of the truth and that true opinions held as dogma lose their living force. Equality is equally contested. Formal equality means equal treatment under law, regardless of status. Equality of opportunity means removing barriers so that positions are open to talents, though it allows unequal outcomes from unequal talents and effort. Equality of outcome means equalising resources or wellbeing, which may require unequal treatment to compensate for disadvantage. Equality of respect, associated with Dworkin, means treating each person as equally worthy of concern, which can justify unequal resources to achieve equal standing. The tension between liberty and equality is real: absolute liberty permits inequalities that undermine equal standing, while absolute equality may require interference that undermines liberty. Liberals resolve the tension differently: some prioritise liberty as a constraint that equality must respect, others treat liberty and equality as two sides of equal respect, so that a liberty that leaves some without the means to exercise it is not yet liberty. Feminist and socialist critics add that formal equality in law can coexist with substantive inequality in family, workplace, and wealth, so the test of equality is not the statute book but lived standing.

Liberalism and theories of justice

Liberalism as a tradition combines individual rights, rule of law, constitutional limits, tolerance, and a market or welfare economy, though liberals disagree about how much state action liberty permits. Classical liberalism, from Locke and Smith, emphasises property, contract, and minimal state, trusting markets to coordinate free persons. Welfare liberalism, from Mill and later Rawls, accepts state action to secure the conditions of liberty, including education, health, and social security, on the ground that liberty without capabilities is formal only. The harm principle, rights as trumps against majority wishes, and the separation of powers are liberal mechanisms for preventing the tyranny of the majority that Tocqueville feared: democracy without rights can oppress minorities as effectively as a monarch. Rawls theory of justice is the most influential liberal theory of distribution. Imagine persons behind a veil of ignorance, knowing nothing about their talents, wealth, gender, race, or conception of the good, choosing principles for the basic structure of society. Rawls argues they would choose two principles in lexical order: first, equal basic liberties for all, including political liberty, freedom of speech, and rule of law; second, social and economic inequalities are permitted only if they are attached to positions open to all under fair equality of opportunity and if they benefit the least advantaged, the difference principle. The difference principle does not demand strict equality: a surgeon may earn more than a cleaner if the incentive structure benefits the least advantaged, for example by ensuring good healthcare for all, but inequalities that only benefit the already advantaged are unjust. Nozick entitlement theory rejects Rawls patterned approach entirely. Justice is historical, not patterned: a distribution is just if it arose from just acquisition, just transfer, and rectification of past injustice, whatever pattern results. Taxing earnings to benefit the least advantaged is, in Nozick famous phrase, on a par with forced labour, because it treats persons talents as a common resource. The Wilt Chamberlain argument illustrates the point: if everyone voluntarily pays to watch a basketball star, the resulting inequality is just because each transfer was voluntary, even though it breaks any preferred pattern. Communitarian justice, associated with Walzer and Sandel, replies that Rawls veil strips persons of the very attachments that give justice meaning: goods have social meanings, like honour, membership, or healthcare, and distribution must follow those meanings within spheres, not a single abstract principle. Sandel critique of the unencumbered self argues that Rawls person, choosing principles without knowing who they are, is not a person at all, since identity is constituted by ends and attachments that cannot be bracketed. The debate therefore turns on the self: Rawls protects the self capacity to revise its ends, Nozick protects its historical entitlements, and communitarians protect its embeddedness.

Marxism, communitarianism, multiculturalism, feminism

Marxism offers the deepest critique of liberal justice by changing the question from distribution to production. In capitalism, workers sell labour power, capitalists own means of production, and surplus value is extracted as profit, so formal equality in contract masks material domination. Alienation describes four separations: from the product, which belongs to another; from the labour process, which is controlled by another; from species being, the creative human essence; and from other workers, who become competitors. Ideology explains why domination is accepted: the ruling ideas are the ideas of the ruling class, presented as natural or universal, so exploitation appears as freedom of contract. Historical materialism claims that economic base, forces and relations of production, conditions the superstructure of law, politics, and ideas, and that class struggle drives history toward a society without classes or state coercion. Liberal critics reply that Marx underestimates the value of rights and the plurality of domination, including gender and race, and that actually existing attempts at classless society reproduced coercion in new forms. Communitarianism, distinct from Marxism, criticises liberalism from within community: MacIntyre argues that modern moral language is fragmented because it has lost the teleological narrative of a tradition, Taylor argues that recognition by others is essential to identity, and Walzer argues that justice is plural across spheres. The communitarian insight is that selves are narratively and socially constituted, so a theory that treats community as a voluntary association misses how language, family, and history make persons who they are. Multiculturalism extends the point to cultural groups: Kymlicka argues that liberalism must protect group-differentiated rights, including language rights and self-government for national minorities, because cultural membership is a primary good that gives individuals a context of choice. Critics warn that group rights can oppress individuals within groups, especially women, and that multiculturalism can harden identities it seeks to protect. Feminism offers the most comprehensive revision: liberal theory traditionally drew a public-private divide, treating family as natural and outside justice, while feminists show that family, care labour, and gender norms distribute power and vulnerability. Wollstonecraft argued for women education as the condition of rational citizenship; Mill argued that the subjection of women is a relic of force, not nature; contemporary feminists argue for recognition of care work, equal pay, reproductive autonomy, and representation, and they challenge theories, including Rawls and Marx, that treat gender as secondary. Intersectionality adds that gender, race, class, and caste interact, so a single-axis theory misses how oppression compounds. For examination answers, the strongest move is to let each critique land and then ask what liberalism must change to answer it without abandoning individual protection: a liberalism that takes Marx on material power, communitarians on belonging, multiculturalists on recognition, and feminists on gender is a revised liberalism, not a defeated one.
