Erich Voegelin, “Kelsen’s Pure Theory of Law” (1927)

Erich Voegelin’s review essay introduces Hans Kelsen’s Allgemeine Staatslehre (1925) to an American audience, explaining its philosophical foundations, constitutional application, and democratic significance. He regards the treatise as a major synthesis of theoretical research and practical experience in Austrian constitutional government. His central claim is that Kelsen’s separation of legal technique from social purposes both clarifies jurisprudence and removes the supposed sanctity of existing institutions, making their purposes available for democratic contestation.

Voegelin first maps the treatise’s three divisions: the nature of the state and its relations to society, morality, and law; the “Statics” of legal validity, including sovereignty and international order; and the “Dynamics” of government, encompassing the layers of lawmaking, official powers, and governmental forms. He then concentrates on the principles underlying this structure. Historically, Kelsen continues the German public-law tradition of Gerber, Laband, and Jellinek. German unification had encouraged attention to concrete positive law at the expense of inherited natural-law speculation. Despite his sharp criticism of his predecessors, Kelsen radicalizes their project rather than simply abandoning it.

The decisive philosophical move is the Neo-Kantian separation of Sein and Sollen, which Voegelin renders as existence and essence. He acknowledges the difficulty and obscurity of this terminology, then explains it through the distinction between a postulate’s ideal meaning and the temporal acts of conceiving or implementing it. Those acts have causes and effects; the meaning itself does not.

Positive law is a system of postulates in the realm of Sollen.

Legal analysis therefore concerns normative meanings rather than the causal processes studied in accounts of social existence. To clarify this distinction for American readers, Voegelin compares Sollen with the realm of essence in critical realism. The distinction does not deny law’s historical origins or practical consequences; it separates these from the specifically legal relation expressed by a norm.

Kelsen’s elementary legal rule connects specified human conduct and events with an official act of coercion. Its center of gravity is enforcement, not the vocabulary in which statutes conventionally describe protected interests.

Legal concepts in the strict sense are confined to enforcing action and operative facts.

Voegelin explains the resulting reduction through rights, duties, privileges, powers, and related concepts familiar to American lawyers. These can be analyzed as conditions under which official action may occur or a legal status may change. Their usefulness for describing social relations remains, but they are not elementary legal concepts. The reduction distinguishes the ethical desirability of protecting an interest from the legal machinery that protects it. A statute’s language of rights must not obscure that difference between purpose and means.

The connection between operative facts and enforcement is imputation, not causality. Theft may remain legally punishable even when the thief escapes: the failure of an expected event does not dissolve the normative relation. Kelsen similarly reconstructs sovereignty and the state as categories internal to legal order. Sovereignty denotes independence from a superior source of legal validity. International recognition and the preservation of obligations across revolutions support treating international law, rather than individual states, as the highest order. The state, understood as substance, denotes the internal coherence of the legal system.

There is actually no difference between the state and the law for all legal purposes.

This qualification matters: Kelsen does not deny a social reality producing law, but refuses to confuse that reality with the juridical concept of the state. A separate sovereign entity standing behind the legal order becomes unnecessary to legal explanation.

Voegelin next tests these principles against the Austrian Constitution, which Kelsen helped draft. His criteria are technical restriction and completeness: constitutional clauses should define operative facts, official actions, and jurisdictions, while avoiding declarations without legal consequences. He praises the document’s precision but acknowledges political compromises and an omitted provision for a particular jurisdictional conflict involving the Constitutional Court. General declarations about democracy or popular participation are assessed by whether they specify enforceable arrangements. Comparison with ambiguities in the United States Constitution reinforces his claim for the Austrian document’s exceptional technical quality.

The conclusion makes the democratic stakes explicit. Separating law from its purposes does not make those purposes irrelevant; it prevents established interests from sheltering behind supposedly unalterable legal standards.

Laws are a technical means for the performance of certain social ends.

Those defending an existing arrangement must consequently defend the equity of their demands. Voegelin directs this argument toward American restrictions on labor legislation associated with due process and Supreme Court power. He also contrasts Kelsen’s approach with the German doctrine of state autolimitation, which could leave a monarch’s supposedly original powers available whenever parliamentary restraint became inconvenient. Democratic government instead requires plainly defined jurisdictions, with every rule traceable to an authorized agency. The essay thus presents pure legal theory as both an analytical achievement and a political transition: from a state imagined as possessing powers beyond law toward a constitutional machinery whose purposes can be openly contested and changed.
