Long before Menger, the ideas that would define Austrian economics—subjective value, scarcity, market price as common estimation—had been worked out by Aristotle, the medieval Schoolmen, and the theologians of Salamanca. Marshalling the revisionist scholarship of Marjorie Grice-Hutchinson, Raymond de Roover, and Emil Kauder, Rothbard overturns the familiar story that Adam Smith and Ricardo founded the science; in his telling they shunted it onto a wrong track, displacing a Continental subjectivism with labor and cost theories. He follows the thread from Buridan, Aquinas, and Covarrubias through Grotius, Turgot, and Say, contending that Menger revived a buried tradition rather than inventing one. The result is polemical historiography—a redrawn genealogy meant to restore forgotten predecessors and prove that marginal utility had roots centuries deep.

The just price is found not by counting the cost but by the common estimation.

An economist who recommends a policy in the name of his science, Rothbard argues, has almost always cheated. Drawing a hard line between ethics—the study of which ends men ought to pursue—and value-free praxeology, he shows that appeals to majority preference, social consensus, or the merits of progressive taxation cannot turn a moral stance into a scientific finding. Demonstrated preference licenses only a narrow claim: voluntary exchange benefits its participants, while state coercion imposes at least one loser. That alone cannot prove laissez-faire. His closing target is Mises, whose utilitarian liberalism assumes men prefer peace and prosperity yet cannot answer those who knowingly choose equality, power, or nationalism. Liberty's defense, he concludes, requires an objective ethics that lies beyond economics.

That leaves him with the first choice: to make crystal clear that he is speaking not as an economist but as a private citizen who is making his own confessedly arbitrary and ad hoc value pronouncements.

Scarcity, valuation, time, uncertainty: Rothbard derives them all from a single axiom—that individuals act consciously toward chosen goals—unfolding an entire economics by verbal deduction rather than equations. Mathematical economics, positivist falsifiability, and econometrics he treats as misreadings of what human choice actually is. The essay's signature move is a friendly break with Mises: where Mises called the action axiom Kantian and a priori, Rothbard grounds it in Aristotelian-Thomist realism, self-evident yet empirical in a sense deeper than post-Humean empiricism allows. He marks praxeology off from psychology, ethics, technology, and history, defends methodological individualism, and denies that heterogeneous historical events can ever test an economic law—though theory remains indispensable for interpreting them.

In short, praxeological economics is the structure of logical implications of the fact that individuals act.

Money re-enters general economic theory through individual action, marginal utility, and market exchange unfolding in time; that is the thread Rothbard follows in reconstructing Mises's monetary theory, which he traces to the 1912 Theory of Money and Credit. The demand for money becomes the demand to hold cash balances, and its purchasing power a heterogeneous array of exchange ratios rather than the inverse of some measurable price level. At the theoretical center stands Mises's regression theorem, which dissolves the apparent circularity of money's value by tracing it back through time to a commodity once valued for direct use. Along the way Rothbard turns the analysis against index-number thinking, Walrasian equilibrium, and government credit expansion, defending commodity money as the one check on political creation of purchasing power.

Every good and service will have an almost infinite array of prices in terms of every other good and service.

Roosevelt rejected international currency stabilization in 1933; a decade later, his administration helped construct a dollar-centered monetary order. In this essay, first published in 1976 and reprinted in 2002, Murray N. Rothbard argues that the apparent reversal concealed a consistent pursuit of freedom to inflate, now joined to American financial predominance. Writing from an explicit preference for gold redemption and market discipline, he connects monetary arrangements to rival banking networks, exporters’ interests, and diplomatic leverage. His account complicates any simple opposition between business and the New Deal: industrialists and bankers could champion reflation while other financial interests resisted it. Following the passage from the failed London Economic Conference to Bretton Woods, readers can examine how domestic monetary discretion and international currency leadership became intertwined.

What makes a statement representative of business opinion rather than merely a statement by businessmen? In this brief, sharply critical review of Alfred L. Thimm’s book, Murray N. Rothbard questions both the evidence for ideological influence and the economic interests concealed by a favorable account of Morgan-group corporatism. He faults Thimm for neglecting cartelization and for treating concentrated financial ownership as a precursor to control by non-owning managers without explaining the contradiction. The review offers a compact encounter with Rothbard’s standards for business history: scholars need not accept revisionist conclusions, but they must engage the research and distinguish professed ideas from institutional influence.

A machine’s productivity may explain its rental income—but why does its purchase price not absorb all its expected future earnings? This distinction anchors Murray N. Rothbard’s 1977 introduction to Frank A. Fetter’s collected essays, Capital, Interest, and Rent. Rothbard presents Fetter as a neglected American contributor to Austrian economics whose account separates payments for productive services from the discounting that determines asset values. His rehabilitation is not unqualified: he defends distinctions between land and produced capital goods that Fetter’s emphasis on capital value tends to obscure. Readers can discover why, in Rothbard’s account, extending rent beyond land and explaining interest through time preference changes the questions distribution theory must answer—and why productivity alone cannot settle them.

Can a protection agency acquire the authority to suppress its competitors without violating the rights it exists to defend? In this 1977 article, Murray N. Rothbard challenges Robert Nozick’s derivation of the minimal state from voluntary exchanges. His anarcho-capitalist perspective makes the decisive issue not an agency’s size or success, but its claimed right to prohibit independent enforcement. Combining rights theory with subjective-value economics, Rothbard argues that fear of unreliable procedures cannot justify coercive monopoly, and that compulsory protection cannot simply be counted as compensation for lost freedom. The dispute sharpens a distinction easily blurred in debates over government: agreement on legal standards need not imply a single institution entitled to enforce them. Readers encounter a libertarian challenge to state authority conducted on the terrain of individual rights that Nozick himself defends.

What exactly counts as money? Rothbard's answer refuses the Chicago school's habit of choosing a monetary aggregate because it correlates with national income—statistical fit, he argues, evades the prior question of what money is. Returning to Mises's definition of money as the generally accepted medium of exchange, he counts demand deposits and other claims the public treats as redeemable at par in standard money, while excluding stocks, bonds, and real estate that are merely liquid and must first be sold. The functional test yields his aggregate Ma: cash plus fixed-rate redeemable claims. A second measure, Mb, isolates newly created bank money entering business credit—the channel that, in Austrian cycle theory, distorts the structure of production toward higher-order capital goods, distinct from deficit finance or consumer lending.

Furthermore, the approach overlooks the fact that statistical correlation cannot establish causal connections; this can only be done by a genuine theory that works with definable and defined concepts.

How did opposition to war cease to be a defining commitment of the American Right? In this historical essay, Murray N. Rothbard sympathetically reconstructs a coalition whose resistance to overseas intervention grew from its hostility to government expansion at home. Figures such as John T. Flynn and Howard Buffett linked military commitments to conscription, debt, economic regimentation, and executive power—not simply to the costs of fighting abroad. Rothbard follows their displacement by Cold War conservatism while showing how former left-wing critics of imperialism came to be classified as reactionaries. His account challenges the equation of conservatism with military activism and offers a concrete history of the tension between defending liberty and maintaining a permanent global security role.

Efficiency, the supposedly neutral yardstick of law and public policy, is a chimera—so runs Rothbard's radicalization of Mario Rizzo's critique. Ends are plural, shifting, and conflicting, he argues, and under genuine uncertainty even an individual cannot be said to choose the 'best' means, since action is itself a process of discovery. Social efficiency fares worse: it presumes ends that can be added and compared across persons, when the real question is whose ends shall rule. On the Austrian theory of cost—subjective, ex ante, vanishing the moment a choice is made—'social cost,' transaction cost, and externality become incoherent, and cost-benefit analysis collapses as an objective guide. The essay carries the point into tort law, defending the misfeasance-nonfeasance line and insisting that justice govern.

Efficiency can never serve as the basis for ethics; on the contrary, ethics must be the guide and touchstone for any consideration of efficiency. Ethics is the primary.

Falling prices need not mean a failing economy, and lower farm returns need not prove irrational investment. These distinctions drive Murray N. Rothbard’s 1980 review of Paul Uselding’s edited Research in Economic History, Volume 4. Challenging studies of Kondratieff long waves, Rothbard asks whether their cycles have been established at all—and whether agricultural prices have become a circular substitute for evidence of economic decline. His emphasis on money, bank credit, and entrepreneurs’ capacity to adjust also shapes his assessment of antebellum agriculture. He contrasts conclusions drawn from a single year with Clarence Danhof’s more cautious, four-decade study of northern farms. The review offers a concrete encounter with Rothbard’s standards of economic explanation: representative evidence, institutional context, and a clear distinction between the pattern being explained and its proposed cause.
