Classical Presupposition Audit: Martha Nussbaum
Source: Published works including Women and Human Development (2000), Upheavals of Thought (2001), Capabilities as Fundamental Entitlements (2003), Frontiers of Justice (2006), Human Rights and Human Capabilities (2007), and Creating Capabilities (2011).
Corpus in use: CPA v1.0. The audit operates from Nussbaum’s own published argumentative record. Nussbaum is Ernst Freund Distinguished Service Professor of Law and Ethics at the University of Chicago, with work spanning ancient philosophy, feminist philosophy, political philosophy, emotions, animal ethics, and the capabilities approach. This run is designed as a model CPA for the non-classically committed philosopher type whose framework preserves serious rational agency while relocating political and ethical attention to embodied flourishing, vulnerability, and externally supported capabilities.
Preliminary Note: Nussbaum’s Position and Its Distinctiveness
Martha Nussbaum presents a different type from both Singer and Rawls. Unlike Singer, she does not relocate moral standing from rational agency to sentience alone. Practical reason remains one of her central human capabilities, and she repeatedly treats choice, critical reflection, liberty of conscience, and the shaping of one’s own life as essential political goals. Unlike Rawls, however, she does not begin from a thin picture of rational contractors abstracted from dependence and vulnerability. She explicitly argues that dignity is the dignity of “a certain sort of animal,” that human beings are mortal and vulnerable, and that any adequate political theory must begin from neediness, dependency, embodiment, and the social conditions of flourishing. Her theory is thus neither dissolutive in Singer’s utilitarian way nor Stoic in the Sterling sense. It preserves agency, but embeds it in an account of life structured by bodily need, emotional attachment, and politically secured capabilities.
The governing move of Nussbaum’s framework is the relocation of political and ethical concern away from the self-governing rational faculty taken in isolation and toward a plural list of central capabilities that a minimally just society must secure up to a threshold. These include life, bodily health, bodily integrity, senses, imagination and thought, emotions, practical reason, affiliation, relation to other species, play, and control over one’s environment. The theory’s center of gravity is therefore not the Stoic claim that externals are indifferent, nor the Singerian claim that sentience alone grounds concern, but the claim that justice requires protecting the external and social bases without which a life worthy of human dignity cannot be lived.
Step 0 — Protocol Activation
The corpus is in view, the sources are restricted to Nussbaum’s own published work and official academic profiles, and no finding below is derived from ideological association or opponent characterization. The analysis proceeds from her own arguments about capabilities, dignity, dependency, emotions, political liberalism, and justice. Self-Audit Complete: result satisfactory. Proceeding to Step 1.
Step 1 — Presupposition Profile
Preliminary Note: The Nussbaum Position
Nussbaum’s position is a politically liberal, capability-based account of justice. It is organized around the claim that governments should secure to each person a threshold level of central capabilities as the basis of a minimally decent human life. She rejects both utilitarian aggregation and Rawls’s primary-goods framework as inadequate to the realities of dependency, gender injustice, disability, and animal life. She also treats emotions as cognitively rich judgments about what matters for our well-being, and she rejects a sharp Kantian split between rational dignity and animal vulnerability. These elements together yield a highly articulated non-classical framework: rational agency is preserved, but no longer treated as self-sufficient, categorically distinct from embodiment, or as the sole locus of value.
P1 — Justice concerns what people are actually able to do and to be; a minimally just society must secure a threshold level of central capabilities.
In Women and Human Development, Nussbaum states that the best account of a basic social minimum focuses on “what people are actually able to do and to be,” and she presents a list of central human capabilities as the basis of political principles and constitutional guarantees. In Capabilities as Fundamental Entitlements, she argues that capabilities can guide a normative conception of social justice only if a definite set of important capabilities is specified and protected up to a threshold for each citizen. This is the load-bearing core of the capabilities approach.
P2 — Human dignity is embodied and animal; an adequate theory of justice must begin from vulnerability, dependence, and need, not from an abstract split between rational person and animal nature.
Nussbaum argues explicitly against the Kantian split between rational dignity and the natural world. She says our dignity is “the dignity of a certain sort of animal,” that human dignity is inseparable from mortality and vulnerability, and that morality and rationality are themselves “thoroughly material and animal.” She treats dependency, care, bodily need, disability, and vulnerability as central facts any adequate theory must build in from the start. This is a load-bearing anthropological premise of her critique of contractarian liberalism.
P3 — Practical reason is a central capability, but it is one capability among several irreducible constituents of a life worthy of dignity.
Nussbaum’s list includes practical reason as the ability to form a conception of the good and critically reflect on one’s life, but it also includes bodily health, bodily integrity, emotions, affiliation, play, and control over one’s environment. She explicitly says the list is irreducibly plural and that one item cannot be compensated for by larger amounts of another. Practical reason is thus essential, but not architecturally sovereign over all the rest.
P4 — Emotions are judgments of value directed toward external objects salient for our well-being; they belong inside ethical reasoning rather than outside it.
In Upheavals of Thought, Nussbaum argues that emotions involve judgments about important things, in which an external object is appraised as salient for one’s well-being. She treats grief, fear, anger, love, and compassion not as irrational residues to be eradicated, but as intelligent, value-laden responses that form part of ethical reasoning. This is a load-bearing claim in her account of the good human life and public culture.
P5 — Moral and political justification proceeds through reflective equilibrium, not through self-evident first principles apprehended directly and held beyond revision.
Nussbaum states in her 2011 interview that her method remains Rawls’s: one searches for reflective equilibrium by considering moral judgments and testing them against major theories. In Women and Human Development she says the list is to be tested against “the most secure of our intuitions” as we seek a reflective equilibrium for political purposes. She also says the list remains open-ended, contestable, and revisable through deliberation and constitutional tradition. This is an explicit methodological commitment.
P6 — The capabilities list is a partial political conception for political purposes only, designed for endorsement under reasonable pluralism rather than as a comprehensive metaphysical doctrine.
Nussbaum repeatedly presents the list in a political-liberal spirit: a set of political goals and constitutional guarantees that can be endorsed by people with different comprehensive views of the good life. In the interview she says the results should be an agreement “for only political purposes,” based on moral foundations for political principles but “not a comprehensive view of human development.” In her response to Rorty, she says citizens with differing religious or secular views cannot accept a metaphysical doctrine as the basis of common political life, but they can accept a partial ethical conception framed for political purposes.
P7 — Moral concern extends beyond reciprocity-based contracting persons to the disabled, the dependent, and nonhuman animals.
Nussbaum criticizes Rawls for excluding from the foundations of justice those who are not fully cooperating contractors, including the disabled and animals. She insists that any adequate theory must incorporate care, dependency, and animal dignity from the beginning. Her human-rights writings also argue that all world citizens are entitled to a decent life under a capability benchmark, and her animal-ethics work extends the capability framework beyond humans. This extension is not peripheral; it is one of the main ways she argues that contractarian liberalism is incomplete.
Step 1 — Domain Mapping
Nussbaum’s record is broadly consistent across domains. In political philosophy, feminist theory, disability theory, emotion theory, and animal ethics, the same structure recurs: embodied dignity, plurality of central capabilities, practical reason as crucial but not exhaustive, and political responsibility for the social bases of flourishing. The main domain variation is not contradiction but emphasis. In methodological discussions she is overtly Rawlsian and reflective-equilibrium based; in anthropological and ethical discussions she is more Aristotelian, speaking of dignity, flourishing, vulnerability, and the worth of specifically human and animal forms of life. This variation matters for the commitment findings below, especially on moral realism and correspondence. Self-Audit Complete: presuppositions are drawn from Nussbaum’s own record, load-bearing rather than peripheral, and the principal domain variation has been mapped. Proceeding to Step 2.
Step 2 — Commitment Audit
Commitment 1 — Substance Dualism: Contrary
Substance dualism requires the rational faculty to be categorically distinct from and prior to bodily, social, and material conditions, and to function as the true locus of identity and value. Nussbaum’s record directly contradicts that structure. She explicitly rejects the split between rational person and animal nature, argues that our dignity is the dignity of a certain sort of animal, and says that morality and rationality are themselves “thoroughly material and animal.” Her central capabilities are defined not around a separate rational self but around embodied life, bodily integrity, emotion, affiliation, and control over one’s environment, with practical reason as one important element within that plural set. This is not merely the absence of dualism; it is an argued rejection of the very anthropology dualism requires.
Finding: Contrary. Nussbaum’s argumentative record requires an embodied, vulnerable, animal conception of dignity that directly opposes the categorical separation of rational self from bodily and worldly conditions.
Commitment 2 — Libertarian Free Will: Partially Aligned
Nussbaum strongly preserves agency in the practical and political sense. Practical reason is one of her central capabilities, defined as the ability to form a conception of the good and engage in critical reflection about one’s life, and she links it to liberty of conscience. Her framework also emphasizes spheres of choice, respect for persons’ own decisions, and political protection of opportunities for self-direction. These features create a genuine affinity with libertarian free will at the level of lived agency.
The residual divergence is that Nussbaum does not ground this agency in a metaphysics of originating assent independent of prior conditions. On the contrary, her framework is saturated with dependence on upbringing, trauma, fear, bodily vulnerability, social injustice, and the external supports required for capability formation. Emotional development can be “blighted” by fear, anxiety, abuse, and neglect; many capabilities require social provision; and human beings are described as profoundly dependent at multiple stages of life. This does not eliminate agency, but it embeds agency within developmental and social conditions in a way that stops short of libertarian origination in the Sterling sense.
Finding: Partially Aligned. Nussbaum preserves meaningful practical agency and reflective choice, but does not defend or require the strong metaphysical claim that the agent is the undetermined first cause of assent.
Commitment 3 — Ethical Intuitionism: Partially Aligned
There is a real affinity here, but not enough for an Aligned finding. Nussbaum clearly believes that political and ethical reasoning is not reducible to utility, preference, or social consensus. She appeals to dignity, worth, flourishing, and the central importance of certain capabilities in any human life. Some items on her list are described as fixed points in our considered judgments, and she says the capability approach is informed by an intuitive idea of a life worthy of human dignity. This is not consequentialist or purely conventional reasoning.
The residual divergence is methodological. Nussbaum does not claim that moral truths are grasped directly and non-inferentially by rational apprehension and then serve as architecturally final grounds. Instead, she explicitly places the list within reflective equilibrium, continued testing, contestability, revision, and political deliberation. The capabilities approach is shaped by intuitions, but it does not rest on intuitionism as the classical commitment defines it.
Finding: Partially Aligned. Nussbaum’s framework contains strong substantive moral judgments not reducible to consequences or agreement, but these are methodologically mediated through reflective equilibrium rather than direct intuitionist apprehension.
Commitment 4 — Foundationalism: Contrary
Foundationalism requires a stopping point: self-evident first principles that are necessary, architecturally prior, and not revisable through ongoing adjustment. Nussbaum explicitly rejects that structure. She says the list is to be tested against intuitions as part of reflective equilibrium, that it remains open-ended and humble, that it can be contested and remade, and that its threshold specifications must be worked out through deliberation within constitutional traditions. In interview as well, she states her method remains Rawls’s reflective equilibrium. This is coherentist and revisable rather than foundationalist.
Finding: Contrary. Nussbaum’s method is explicitly anti-foundationalist in the CPA sense: principles and judgments are reciprocally adjusted, and no architecturally final self-evident foundation governs the structure.
Commitment 5 — Correspondence Theory of Truth: Partially Aligned
Nussbaum’s factual claims about deprivation, gender injustice, dependency, disability, education, and social provision are plainly truth-apt in the ordinary correspondence sense. Her arguments about what governments do or fail to do, and about the empirical effects of abuse, neglect, education, or bodily insecurity, presuppose that there is a fact of the matter independent of belief or consensus.
The divergence concerns moral and political truth. Nussbaum often speaks as though there are objective truths about dignity and what a life worthy of human dignity requires. But the justificatory method she actually uses is political-liberal and reflective-equilibrium based. The list is framed for political purposes, open to revision, and specified through deliberation and consensus within pluralist constitutional traditions. That means moral-political truth in her framework is not simply stated as direct correspondence to independently apprehended moral facts; it is partially procedural and constructivist.
Finding: Partially Aligned. Nussbaum relies on correspondence for empirical claims and speaks in morally realist ways, but her political and ethical justification is not a pure correspondence account in the classical sense.
Commitment 6 — Moral Realism: Partially Aligned
Nussbaum is not a subjectivist, emotivist, or relativist. She argues that some deprivations are genuinely terrible across cultures, that some capabilities are of central importance in any human life, that each person is an end, and that justice makes objective demands independent of adaptive preferences or local acceptance. Her critique of utility and adaptive preference only makes sense if there are standards of justice that do not collapse into whatever people happen to prefer under unjust conditions.
The residual divergence is that Nussbaum does not ground these truths as objective moral facts discoverable in the strong classical way. She frames the list as a political conception for political purposes, compatible with multiple comprehensive doctrines, and methodologically worked out through reflective equilibrium. Thus her realism is genuine but thinner and more constructivist than the Sterling commitment requires.
Finding: Partially Aligned. Nussbaum clearly treats justice and dignity as more than preference or consensus, but her political liberalism and anti-foundational method prevent a full realist finding in the classical sense.
Step 2 — Self-Audit
All major presuppositions in the profile have been audited. Non-Operative has not been used to avoid Contrary findings. The strongest divergence lies on embodiment and method, not on sympathy or antipathy to Nussbaum’s politics. The same findings would follow for any figure whose framework combined embodied dignity, reflective equilibrium, and political-liberal capability thresholds in the same way. Self-Audit Complete: result satisfactory. Proceeding to Step 3.
Step 3 — Dissolution Finding
Commitment 1 is Contrary. Commitment 2 is Partially Aligned.
Finding: Partial Dissolution.
The ground of the Contrary finding on C1 is clear: Nussbaum’s framework explicitly denies the separation of rational dignity from embodied animality and treats the self as vulnerable, dependent, materially situated, and dignified precisely as that sort of animal being. The ground of the Partially Aligned finding on C2 is equally clear: her framework preserves practical reason, liberty of conscience, and reflective life-planning as central capabilities, so it does not eliminate agency altogether.
The result is a genuine Partial Dissolution rather than Full Dissolution. An agent who adopts Nussbaum’s framework does not dissolve himself into an impersonal welfare calculus, nor into total structural determinism. He retains a self-description as a chooser, planner, critic, and rational agent. But he does accept a framework in which that agency is no longer ontologically prior to embodiment, need, vulnerability, social dependency, and the externally supported conditions of flourishing. The prohairesis is not extinguished; it is partially subordinated to a picture in which the basic terms of justice and dignity are defined through embodied capability rather than through the sovereign rational faculty alone. This is a finding about the framework’s implication for adopters, not a finding about Nussbaum’s own inner life.
Self-Audit Complete: the dissolution finding follows mechanically from C1 Contrary and C2 Partially Aligned, and it has been stated as a framework implication rather than a psychological verdict. Proceeding to Step 4.

The deepest point of divergence is Commitment 1: Nussbaum’s explicit rejection of the split between rational dignity and embodied animality. The second deepest is Commitment 4: her overtly reflective-equilibrium, revisable, political-liberal method. The strongest points of alignment are C2 and C6 in their limited forms: she preserves serious agency and she is plainly not a relativist or pure constructivist of preference.
Part B — Dissolution Finding
Partial Dissolution. Nussbaum’s framework preserves practical reason and reflective agency, but it denies the ontological priority of the rational faculty and relocates dignity into the life of a vulnerable, embodied, dependent animal whose flourishing requires threshold support across a plurality of externally conditioned capabilities. The framework therefore partially compromises the Sterling picture of the self while not abolishing agency outright.
Part C — Agent-Level Implication
An agent who adopts Nussbaum’s framework as his governing self-description does not adopt Singer’s dissolution into sentience or aggregate welfare. He still understands himself as a chooser capable of practical reason, critical reflection, and life-planning. But he no longer understands himself as a self-sufficient rational faculty for whom externals are indifferent. He understands himself instead as an embodied and vulnerable being whose dignity is inseparable from bodily health, integrity, emotion, affiliation, and social conditions, and whose political life is rightly organized around securing threshold access to these capabilities. He is thus committed to a picture in which external conditions are not morally indifferent but partially constitutive of the justice owed to a life of dignity. That is the precise CPA significance of Nussbaum’s framework.
The Nussbaum Diagnosis
Nussbaum is best understood as a philosopher of embodied dignity without full dissolution. She preserves a serious account of rational agency, but embeds it in an anthropology of vulnerability and an irreducibly plural account of flourishing. This makes her a particularly important non-classical case. Unlike Singer, she does not invert the moral criterion so radically that rational agency becomes morally irrelevant. Unlike Rawls, she does not remain at the level of primary goods and contracting persons. She pushes political philosophy toward the concrete life of dependent, embodied, emotionally attached beings and argues that justice must secure their capabilities from the beginning. From the CPA standpoint, this produces a framework that is more anthropologically concrete and more externalist than Rawls, but less dissolutive than Singer.
Corpus Boundary Declaration
This audit does not say that Nussbaum’s politics are correct or incorrect, that capability thresholds should or should not be adopted, or that her institutional proposals succeed or fail as policy. It says only that her own argumentative record requires a specific philosophical structure: embodied dignity, plural capabilities, reflective-equilibrium justification, and political concern with externally supported flourishing. The CPA finding is about those presuppositions and what they imply for an agent who adopts them as a governing account of himself. Self-Audit Complete. CPA run complete.
