My friend Juan Fernando Carpio has translated Legal Foundations of a Free Society (Houston, Texas: Papinian Press, 2023) into Spanish, under the title Fundamentos Legales de una Sociedad Libre. He has also translated the works of Hans-Hermann Hoppe and George Reisman into Spanish. He discusses his forthcoming translation in Juan Fernando Carpio, “Legal Foundations of a Free Society,” Juan Fernando Carpio (Medium) (Oct 27, 2025) (translation below).
The print version of is in preparation and will be announced presently. A translation of his Translator’s Note and the back cover text is appended below.

Libertarian legal thought finds its greatest contemporary exponent
In Legal Foundations of a Free Society, Stephan Kinsella articulates the complete theory of property law, contracts, justice, and human freedom in general, from a rigorous praxeological, Rothbardian, and Hoppean perspective.
I am translating Stephan Kinsella’s Legal Foundations of a Free Society into Spanish!
As a scholar and enthusiast of libertarian ideas that contrast with left- and right-wing socialisms, I have admired for years the work of N. Stephan Kinsella, a key thinker alongside Rothbard and Hoppe.* His critiques of intellectual property and his defense of private property as the foundation of a free society have inspired me, as I mentioned on X.com: an essential author for understanding scarcity, rights, and ethics.
Translating this book is, for me, partly repaying an intellectual debt that many of us owe to Kinsella.
I am translating his masterpiece into Spanish to make it accessible to more Spanish speakers, freeing them from the rampant statism in Latin America and Spain. News about the progress and publication will follow soon. Stay tuned! If you are looking for readings that cure statism and paternalism at their roots, with great academic power yet accessible to all types of readers, this will be essential.
In the meantime, the book in English can be found here.
*Frankly, Rothbard-Hoppe-Kinsella represents for me the most elaborate, up-to-date, coherent, and powerful libertarian thought that can be found today, in a succession of successes, dialogue, development, and mutual corrections that is very interesting in itself.

Translator’s Note
Legal Foundations of a Free Society is not a casual compilation: it is the logical conclusion of an intellectual edifice that began with Mises, took shape with Rothbard, and attained greater philosophical rigor with Hoppe. Stephan Kinsella, a jurist and direct disciple of this tradition, here organizes three decades of work around an idea as simple as it is implacable: if freedom has a foundation, that foundation is legal. And if Law is to be coherent, it can only be derived from property, from the ontological structure of scarcity.
The book, published in 2023, is a systematic synthesis. Kinsella does not limit himself to expounding theory: he reconstructs it on the strongest available foundations and contributions to date.
In Part I, he describes his own intellectual evolution—from Objectivist to Rothbardian—and explains how he discovered in Hoppe’s Argumentation
In Part II, he develops the normative foundations: self-possession, original appropriation (homesteading), contract, and
Part III addresses the causal and legal framework: how aggression is identified objectively and how the links between action, harm, and restitution are established. This is where Kinsella dismantles the confusion between moral cause and legal cause, following M. N. Rothbard and classical Roman law.
In Part IV the author applies the theory to the most controversial cases: intellectual property, the discovery of law, legislation, and judicial monopoly. The chapters devoted to “Law and Intellectual Property in a Stateless Society” and “Legislation and the Discovery of Law” are masterful pieces: they condense twenty years of debate with jurists, economists, and philosophers. Kinsella demonstrates, with Hoppean rigor and elegance, that all genuine law is discovered, not created; that patents and copyrights are not extensions of law but violations of it; and that legislative monopoly destroys the social function of law, turning justice into central planning.
Parts V and VI broaden the theoretical scope. They include essays on knowledge, calculation, conflict, and law; on the epistemological limits of the State; and on polycentric legal order—what others would call “anarcho-capitalism” or even better, a kritarchy, but which Kinsella describes as the only structure compatible with non-aggression.
The book closes with a series of personal and retrospective texts, including his dialogue with J. Neil Schulman and his speech “Libertarianism Fifty Years Later,” which functions almost as a generational epilogue: the realization that the intellectual project begun by Mises has produced a complete and self-consistent legal theory.
What is extraordinary about the book is not only its content but its method. Kinsella reasons a priori, supported by the conceptual discipline of Praxeology. He does not cite to adorn, but to sustain. He does not speculate or assume; he deduces. His style may seem dry, but every sentence can have the precision of a mathematical demonstration.
His central thesis runs through the entire work: law arises to resolve conflicts over scarce resources; where there is no scarcity, there is no conflict, and where there is no conflict, there is no law. From that observation all legitimate institutions—property, contract, restitution—are derived, and all statist fictions—legislation, judicial monopoly, intellectual property—collapse.
This Spanish edition seeks to preserve that clarity without losing its edge. Italics, notes, titles, and original terminology have been respected rigorously. I thank Ángel Cárcamo, Marco Tulio León, A. Rameth Aréstegui, Oscar Grau, and Carmen Tobar Subía for their various revisions and critiques.
Whoever reads this book attentively will understand in an integrated way why Law is not decreed but discovered; why freedom is not a political aspiration but a logical consequence; and why every form of legal coercion (aggression) over non-scarce goods—including intellectual property—is, in the final analysis, a performative contradiction.
Legal Foundations of a Free Society is, almost certainly, the most rigorous work of libertarian legal theory written to date. Translating it has been an honor and a responsibility: that of preserving, in another language, a logical structure that frankly admits no nonsense.

Back Cover Text
Legal Foundations of a Free Society is an updated selection of articles published over three decades dealing with a variety of issues in libertarian rights and legal theory, including the nature and foundations of libertarianism, rights and punishment theory, causation and responsibility, contract theory, and intellectual property. The chapters have been significantly revised and updated and integrated with each other with extensive cross-references, and supplemented with an extensive bibliography and index.
… more than 40 years after the first publication of Rothbard’s Ethics of Liberty and characterized by much practical disappointment and increasing theoretical confusion, the publication of Stephan Kinsella’s present work must be considered a most welcome sign of renewed hope and new, refreshing intellectual inspiration. Indeed, with this work, that has been in the making for more than two decades, Kinsella has produced no less than an intellectual landmark, establishing himself as the leading legal theorist and the foremost libertarian thinker of his generation.
While following in Rothbard’s footsteps, Kinsella’s work does not merely rehash what has been said or written before. Rather, having absorbed as well all of the relevant literature that has appeared during the last few decades since Rothbard’s passing, Kinsella in the following offers some fresh perspectives and an innovative approach to the age-old quest for justice, and he adds several highly significant refinements and improvements and some centrally important new insights to the theories of personhood, property and contract, most famously some radical criticism and rejection of the idea of “intellectual property” and “intellectual property rights.”
Henceforth, then, all essential studies in the philosophy of law and the field of legal theory will have to take full account of the theories and criticisms expounded by Kinsella.
