Hans-Hermann Hoppe develops this position primarily in A Theory of Socialism and Capitalism (1989) and in the essay "The Justice of Economic Efficiency" (1988), later expanded across several papers and collected in The Economics and Ethics of Private Property (1993).

It is an explicit attempt to resolve the problem left open by Murray Rothbard (1926–1995): how to move from "is" (human nature) to "ought" (the non-aggression principle) without committing the naturalistic fallacy. Hoppe argues that he found an a priori and irrefutable foundation, stronger than that offered by his mentor.

1. The Starting Point: Argumentation as an Inescapable Fact

Hoppe's strategy is transcendental, inspired by the discourse ethics and universal pragmatics of Jürgen Habermas and Karl-Otto Apel (curiously, two left-leaning German philosophers whose methodology Hoppe borrows to reach strictly libertarian conclusions).

The argument begins with a seemingly trivial observation: anyone who seeks to dispute or justify any norm is already engaged in argumentation. And argumentation is not just any act: it is a purposeful, proposition-claiming activity that presupposes certain necessary conditions in order to take place. In other words, there are truths that cannot be denied without falling into a performative contradiction (a contradiction between what is asserted propositionally and what is performed in the act of asserting it).

A classic illustration of the method: claiming "there is no truth" is performatively self-refuting, because one asserts that claim as true. Hoppe applies this exact logic to normative ethics.

2. The Central Argument

The standard reconstruction of Hoppe's argument proceeds through the following steps:

Argumentation is an action. It is not a purely mental phenomenon; it requires the use of one's own body (the vocal apparatus, writing, or any communicative medium) to propose and evaluate propositions.
Argumentation presupposes exclusive control over one's own body. For an exchange of arguments to take place, each participant must be able to freely decide what to say and when, without another party physically controlling their body. If someone physically coerced you into uttering words, you would no longer be arguing: you would merely be used as an instrument.
Therefore, anyone who engages in argumentation implicitly acknowledges, by the very act of participating in it, that both they and their interlocutor possess exclusive property rights over their respective bodies. To verbally deny this ("I have no right to my body" or "you have no right to yours") is a performative contradiction: one would be autonomously deploying one's own body to deny that very autonomy.
Furthermore, arguing presupposes that the parties have not resorted to physical aggression to "win" the dispute, but have agreed instead to resolve their disagreement through reasons. For this reason, Hoppe argues that the non-aggression principle itself is presupposed by anyone who argues either in its favor or against it.

Hoppe's conclusion is radical: any attempt to justify any norm that deviates from self-ownership and non-aggression falls into performative contradiction, because the very act of propositional justification already presupposes those norms. This leads him to assert that libertarianism is not merely one moral option among many, but the only ethic that can be propositionally defended without self-contradiction.

3. Extension to External Property

Hoppe extends the argument beyond the physical body: since argumentation also requires the use of scarce resources (at minimum the standing room where one is located, the air, and time), he argues that the same line of reasoning validates the Lockean-Rothbardian principle of original appropriation by "first use" (homesteading): any alternative norm regarding the use of scarce resources (for example, that an unrelated third party has the right to decide) would generate conflicts that argumentation itself aims to resolve, or would prove practically unworkable within the practice of debate.

4. Why He Is Distinguished from Rothbard

Rothbard grounded self-ownership in a theory of rational human nature (Aristotelian-Thomistic natural law): man must be free because his nature requires reason and choice. Hoppe regards this foundation as remaining dependent upon substantive premises about "what is good for man" that an opponent could contest.

His own argument aims to be more parsimonious: it requires no theory of human nature or human flourishing, only the logical analysis of what argumentation itself presupposes. Thus, Hoppe presents it as an a priori foundation (analogous to the axioms of Misesian praxeology, of which Hoppe is also an intellectual heir), rather than an empirical or substantive metaphysical claim. In this sense, he combines Misesian apriorism with Rothbard's objective rights, while fundamentally altering the method of justification.

5. Controversial Applications

Hoppe uses this framework to argue, among other things, that:

The State is inherently illegitimate because its very existence (coercive taxation, monopoly on ultimate decision-making and jurisdiction) represents a structural denial of the principle presupposed by every participant in argumentation.
Democracy is inferior to monarchy in terms of time preference and respect for private property (a thesis developed in Democracy: The God That Failed, 2001), although this steps beyond argumentation ethics proper into his political sociology, which is far more controversial and contested even within libertarian circles.

6. Main Critiques

This is likely the most technically scrutinized libertarian argument in analytic philosophy. The most common objections include:

From description to norm: The argument demonstrates, at most, that arguing presupposes certain factual conditions (bodily control in order to speak). But it does not follow that those conditions must be morally respected outside the act of arguing. An enslaved person in chains can still argue with their captor; that they are able to do so does not prove that the captor acknowledges a moral right to liberty. This is the most frequently cited critique (voiced, among others, with reservations by Murray Rothbard himself, and later elaborated by David Gordon and referenced indirectly by Robert Nozick).
Confusion between pragmatic presupposition and moral validity: That a speech act presupposes X does not entail that X is an enforceable, universal right outside of that act. One might presuppose "I have factual control of my body at this moment" without that entailing "I have an exclusive, lifelong moral right to it against all persons."
Limited scope: Even if the argument held, it would only establish valid norms between the specific parties arguing with each other at that moment. It is far from obvious how it extends to third parties not participating in the discussion, or to ownership of external scarce resources (the transition from "I control my vocal cords while speaking" to "I have an exclusive property right over the parcel of land I occupy" is an additional leap distinct from the argument concerning one's body).
Begging the question (petitio principii): Critics such as Jeremy Waldron and others contend that the argument must already assume a robust concept of "property" and "rights" to get off the ground, which is precisely what needs to be demonstrated; it shows at best that one must presuppose factual control, not property in a fully normative sense.
Comparison with Habermas/Apel: Ironically, Karl-Otto Apel himself dismissed Hoppe's application of discourse ethics as a distortion: the transcendental pragmatics of Habermas and Apel sought to ground universalist, egalitarian norms (closer to social democracy or left-liberalism), not near-absolute private property rights. The debate over whether the transcendental method can legitimately yield Hoppe's conclusions remains open.
Robert Nozick and side constraints: While Hoppe shares Nozick's view of rights as side constraints, he does not offer the same type of justification (Nozick did not claim a transcendental proof, but appealed to a Kantian moral intuition regarding the separateness and inviolability of persons as "ends in themselves").

7. Assessment Within the Libertarian Tradition

Within libertarianism itself, reception has been polarized: some Rothbardians (such as Walter Block and Stephan Kinsella) embrace it as the missing capstone of Rothbard's ethical system; other libertarians (notably Bryan Caplan in his widely circulated essay, along with most consequentialist libertarians) regard it as a logical failure—more clever than sound—and prefer returning to Misesian or Hayekian defenses, or to a pluralism of reasons (rights plus consequences) without claiming an absolute proof.

8. Placement on the Conceptual Map

	Foundation	Method
Locke	Theological natural law	Exegesis of reason + revelation
Mises	Subjective ends, effective means	Praxeology (a priori reasoning on human action)
Hayek	Cultural evolution of rules	Epistemology + history
Rothbard	Secular natural law, human nature	Aristotelian-Thomistic ethics
Hoppe	Presuppositions of argumentation	Transcendental pragmatics (a priori reasoning on discourse)

In a sense, Hoppe closes the cycle of attempts to establish an a priori foundation for libertarianism: he borrows the method from Mises (necessary, non-empirical truths) and the substantive content from Rothbard (self-ownership and the NAP), while replacing the justification based on human nature with a theory of communicative action and discourse.
