Introduction
Law claims authority: it purports not merely to threaten sanctions but to impose obligations and provide reasons for action. Explaining this normativity—law's reason-giving force—divides positivists from natural lawyers. Positivists contend that law's normativity derives from social facts (conventions, acceptance, institutional practice); natural lawyers insist that normativity requires moral grounding. This essay argues that natural law offers a more satisfactory account, because purely social-fact explanations either collapse into predictions of coercion or covertly presuppose the evaluative perspective natural law makes explicit. After outlining Hart's positivist account and Raz's refinement, I examine Finnis's natural law alternative, assess objections, and conclude that law's normativity is intelligible only within a framework acknowledging law's orientation to justice and the common good.
Hart's positivism: normativity as social rule
Hart's Concept of Law explains legal obligation by analogy with game rules. Officials and citizens accept a rule of recognition identifying valid law; this acceptance generates an internal point of view, treating law as reason-giving. Legal obligation is thus a social fact: to say X is legally obliged is to assert that a valid rule, accepted by officials, imposes a duty on X. This avoids reducing law to coercion (Austin's gunman problem) and accommodates the phenomenology of legal practice—judges deliberate about what law requires, not merely what will avoid sanction.
But Hart's account faces a dilemma. If the internal point of view is merely participants believing law obligates, without law actually providing reasons, then normativity reduces to a shared illusion—sophisticated coercion, not genuine authority. If, however, the rule of recognition does generate genuine reasons, we must ask why. Hart suggests that acceptance itself grounds obligation (officials accept the rule, so it binds them). Yet this is circular: acceptance explains normativity only if acceptance is reason-giving, which is precisely what requires explanation. Natural lawyers argue that the rule of recognition is reason-giving only if law serves valuable ends—coordination, justice, the common good. Hart's social-rule positivism thus covertly presupposes evaluation.
Raz's service conception
Raz offers a more robust positivist account. Law claims legitimate authority: it purports to mediate between subjects and reasons that apply to them independently. A legal directive is justified if it helps subjects conform better to background reasons (the 'normal justification thesis'). This explains normativity without moral criteria for validity: law's normativity derives from its claim to authority and, when justified, from its actual service of pre-existing reasons.
Raz's account is superior to Hart's but concedes much to natural law. Law's claim to authority is intelligible only if oriented to reasons grounded in human good (what else could justify authority?). Raz distinguishes law's nature (the claim to authority) from its justification (actual service of reasons), insisting wicked law is still law. But this distinction is unstable. A legal system systematically indifferent to subjects' reasons—pure predation—lacks the feature (claim to authority) Raz treats as essential. Either such a system is not law (natural law conclusion) or 'claim to authority' does no conceptual work and reduces to coercion (Austin redux). Natural lawyers urge that Raz's account is best understood as natural law: law's intelligibility requires orientation to justice, even if particular laws fail.
Finnis's natural law
Finnis grounds normativity in practical reason's identification of basic human goods and law's role in securing them. Law solves coordination problems, enabling individuals and communities to pursue flourishing. Legal authority is justified insofar as law serves the common good—conditions facilitating realisation of basic goods. Legal obligation arises not from bare social fact but from moral reasons: law obligates when and because it genuinely serves these goods (or at least does not egregiously undermine them). Wicked law lacks the moral quality making law fully law; it is law in a 'watered-down' sense, lacking authority.
This explains normativity without circularity. Law provides reasons because it serves valuable ends grasped by practical reason. The internal point of view is justified: participants are correct to treat law as reason-giving when law fulfils its function. Positivism, by contrast, either leaves normativity mysterious (Hart) or explains it in terms that presuppose moral evaluation (Raz).
Objections and replies
Postivists object that natural law conflates law as it is and law as it ought to be. Wicked law exists; Nazi statutes were law, however immoral. Finnis's focal-meaning strategy answers this: natural law describes law's central case, not all instances. Defective law remains 'law' in a nominal sense (like a defective knife is still called a knife), but the fully realised concept integrates moral criteria. This is methodologically sound: we understand institutions by their point, not by defective instances. Positivists retort that this is stipulative, not explanatory. But the explanatory burden lies with positivists: why does law claim authority if not because it purports to serve justice? No positivist answer avoids covert evaluation.
A second objection: natural law invites judicial overreach. If judges may declare unjust statutes invalid, democracy and rule of law are imperilled. But natural lawyers need not endorse routine judicial invalidation. Finnis acknowledges defeasible obligation even to unjust law (for reasons of stability, fairness); Aquinas permits obedience to avoid scandal. The critical question is whether judges in principle may refuse recognition of egregious injustice (Oppenheimer, Radbruch cases). Positivism's refusal to countenance this risks complicity in atrocity; natural law's permission honours the moral limits of legal authority.
Conclusion
Natural law offers a more satisfactory account of normativity because it explains why law claims authority and when that claim is justified. Positivism either reduces normativity to coercion (Austin) or presupposes evaluation while denying it (Hart, Raz). Finnis's integration of practical reason and law's service to the common good makes law's reason-giving force intelligible without circularity. Objections about conceptual clarity and judicial restraint are answerable. While positivism usefully distinguishes law from morality for some analytical purposes, understanding law's nature—its claim to bind in conscience, its orientation to justice—requires the resources of natural law.

The foregoing argument can be deepened by examining specific points of contention and considering whether a middle path—inclusive legal positivism or Dworkinian interpretivism—might capture natural law insights within a positivist framework.
Inclusive legal positivism
Inclusive (or soft) legal positivists (Coleman, Waluchow) argue that the rule of recognition may incorporate moral criteria without abandoning positivism's core: the social-fact thesis (law's existence depends on social facts). In some legal systems, validity turns on moral tests (e.g. constitutionality, 'due process'); in others it does not. This accommodates natural law's observation that morality often figures in legal reasoning, while preserving the separation thesis: the connection is contingent, not necessary.
But this concession undermines the positivist project. If law's existence can depend on moral facts, then identifying law requires moral evaluation—precisely what natural law asserts. The dispute shifts to whether the connection is necessary or contingent, a question that turns on law's nature. Finnis argues that law's intelligibility as a reason-giving practice presupposes orientation to justice; thus the connection is necessary to law's central case, even if defective systems lack it. Inclusive positivism, by allowing moral criteria, tacitly admits natural law's claim that law and morality are deeply entangled; it merely insists this is optional. Yet if the best legal systems integrate morality, and if this integration explains law's normativity, then natural law's focal-meaning account is vindicated.
Dworkin's challenge to positivism
Dworkin argued that positivism misdescribes legal practice. Judges in hard cases (where rules run out) do not exercise discretion (a positivist claim) but identify law by constructing the best moral justification of existing legal materials. Law includes not only rules but also principles—moral standards that provide justification. This 'law as integrity' denies the separation thesis: morality is internal to law, not an external standard.
Dworkin is often classed as neither positivist nor classical natural lawyer. But his theory shares natural law's core commitment: law cannot be identified without moral reasoning. Finnis endorses much of Dworkin's critique of Hart, though Finnis grounds normativity in practical reason and basic goods rather than interpretive coherence. Whether Dworkin is a natural lawyer is semantic; substantively, his theory aligns with natural law against positivism on the entanglement of law and morality.
The Nazi law debate revisited
Much of the natural law/positivism dispute centres on how to conceptualise Nazi 'law'. Hart insisted Nazi statutes were law—unjust, abhorrent, but law nonetheless. Denying this, Hart argued, obscures the moral horror: if Nazi rules were not law, we cannot condemn them as unjust law. Natural lawyers reply that calling Nazi decrees 'law' dignifies them with authority they lacked; better to say they were exercises of naked power, lacking law's essential character.
Fuller's response is instructive. He documented Nazi legal chaos: secret orders, retroactive decrees, arbitrary enforcement. On Fuller's criteria, Nazi Germany lacked law in many domains—not because the rules were unjust (substantive complaint) but because they failed to guide conduct (procedural deficiency). This is a powerful reply: if law requires minimum formal justice, many Nazi 'laws' fail as law even on non-moral criteria. Yet critics note that some Nazi laws were clear, prospective, and public—persecution codified and administered 'legally'. Fuller might respond that systemic disregard for legality (which Nazi Germany exhibited) undermines law's existence wholesale; but this remains controversial.
The debate matters for transitional justice. If Nazi 'laws' were not law, prosecuting border guards involves no retroactivity (they violated law, not merely post-hoc morality). If Nazi 'laws' were law, prosecutions seem retrospective. Natural lawyers and Radbruch courts finesse this by holding egregiously unjust 'laws' void ab initio—never valid—so no retroactivity occurs. Positivists charge this is legal fiction; natural lawyers reply it is moral truth.
Practical implications
Natural law's account of normativity has practical consequences. If law obligates only when morally justified, civil disobedience and revolution are more readily defensible. Positivism's separation of law and morality arguably promotes stability: even if law is unjust, it remains law, and disobedience is legally (if not morally) wrong. Natural law risks anarchy if every citizen judges law's validity. But this objection overstates the risk. Finnis, Aquinas, and Fuller all counsel prudence: even defective law may bind pro tanto (for coordination, avoiding worse outcomes). Natural law permits disobedience in extremis, not routinely—a morally defensible position. Positivism's risk is complicity: if officials 'just follow orders' because Nazi decrees were legally valid, atrocity proceeds unchallenged. Natural law equips citizens and judges to resist.
Conclusion of extended discussion
Natural law's account of normativity is superior because it integrates law's phenomenology (participants treat law as reason-giving), its justification (law serves the common good), and its limits (egregiously unjust 'law' lacks authority). Positivism's attempts to explain normativity via social rules (Hart) or claims to authority (Raz) either collapse into coercion or presuppose evaluation. Inclusive legal positivism and Dworkinian interpretivism move toward natural law, acknowledging that morality is internal to law. While positivism has value in distinguishing law from aspirational morality, explaining law's nature—its normativity, authority, and claim on conscience—requires natural law's resources. The tradition from Aquinas through Fuller to Finnis offers the most satisfactory account of why law binds and when it does not.
