Spheres of Justice: A Defense of Pluralism and Equality

Complex equality is Walzer's alternative to the 'simple equality' he associates with Rawls and other liberal theorists. Simple equality seeks to redistribute a single dominant good, typically money, so that everyone has roughly the same amount. Walzer argues this is misguided because it treats all goods as commensurable and ignores their distinct social meanings [citation:1]. Complex equality requires instead that each good be distributed according to its own sphere's principles—health care to the sick, offices to the qualified—and that no sphere's goods be convertible into another's. A society is just when no one can convert advantage in one sphere into domination over others [citation:6].

Walzer introduced the framework of distinct 'spheres of justice,' each defined by the shared social meanings of the goods within it. His book examines spheres including membership, security and welfare, money and commodities, office, hard work, free time, education, kinship and love, divine grace, recognition, and political power [citation:1]. The theory has been applied to an unusually wide range of practical contexts, including higher education in Malaysia, affordable housing in the US, children's rights in El Salvador, the practice of paying research subjects in clinical trials, personal data protection, and insolvency creditor hierarchies [citation:3]. A 2025 volume reassessed its relevance for social justice in the 2020s [citation:14].

Rawls argues from abstract first principles, using the original position and the veil of ignorance to derive principles of justice that apply universally. Walzer explicitly rejects this approach. He denies that there are 'primary goods' that can be desired and allocated in abstraction from any specific society [citation:1]. Instead, his method is interpretive: he works from the shared understandings already latent in a community's practices and institutions, treating political theory as a matter of interpreting what citizens already believe about their social goods rather than climbing a mountain to survey all possible worlds [citation:3][citation:6]. This makes his theory both more concrete and, critics charge, more relativistic.

The most persistent criticism concerns the theory's relativism. If justice is defined by a community's shared understandings, what resources does Walzer have to criticize a community whose understandings are unjust? Richard Arneson's 'Against Complex Equality' argues that the theory cannot adequately address inequalities that persist within spheres, and that Walzer's assumption that losses in one sphere won't affect others is empirically dubious [citation:8]. Others argue that Walzer assumes a degree of political autonomy and immunity from domination by interest and power that may not exist in actual democracies [citation:7]. Walzer has responded that some goods, like membership and basic welfare, are grounded in a 'minimal morality' that constrains what communities can legitimately do [citation:19].

Walzer begins with membership because it poses the most fundamental distributive question: before we can discuss justice among members, we must ask who belongs. He argues that admission and exclusion are at the core of communal independence and self-determination; without them, there can be no 'communities of character' [citation:2]. The community alone decides on admission, emigration, and citizenship, but Walzer also argues for a policy of inclusiveness toward present inhabitants like immigrants and guest workers, because it is tyranny to rule over strangers [citation:2]. This chapter has been among the most debated, with critics questioning whether Walzer's conception of community can ground the inviolable right of closure he defends.

Spheres of Justice is recognized as a classic of twentieth-century political thought and a founding text of the communitarian critique of liberalism [citation:6]. Its influence has operated on three levels: micro-level appropriation of specific ideas, general social justice debates, and methodological influence on how theorists do political theory [citation:10]. A 2025 edited volume, Walzer and Justice: Spheres of Justice in the 2020s, reassesses its contributions, highlighting the social-democratic nature of Walzer's theory as an aid to rethinking egalitarian politics today [citation:14]. The book remains widely taught and debated, though its interpretive method and relativist implications continue to generate criticism.
