Definitions of a science are usually dismissed as verbal preliminaries; here they become the record of a discipline learning to see its own object. Tracing the long argument over what makes analysis specifically "economic," Kirzner follows the movement from the classical science of wealth, through material welfare and the figure of homo oeconomicus, to Robbins's austere formulation of economics as the relation between ends and scarce means. Each definition, he shows, both advances and constrains: wealth fixes attention on things rather than valuation, while money mistakes one powerful manifestation for the ground. The Methodenstreit hovers over the whole inquiry. Kirzner's destination is praxeological—the economic point of view as a branch of Mises's science of human action, in which means become means only within purposeful conduct, not through mechanical allocation.

“Economics,” wrote Professor Robbins, “is the science which studies human behavior as a relationship between ends and scarce means which have alternative uses.”

All economics unfolds from a single axiom: that human action is purposeful behavior. Building deductively from that Misesian starting point, the first volume of Rothbard's treatise—here in the German translation of the 1962 English original—derives the whole architecture of the market: marginal utility and the ordinal value scale, the emergence of money from barter through Mises's regression theorem, time preference and the pure rate of interest, and the evenly rotating economy as a mental tool for isolating market tendencies. Rothbard insists throughout that costs of production are at the mercy of the final price, not the reverse, and that capital goods are intermediate stations reducible to land, labor, and time rather than an independent source of value. Praxeology, not psychology or mathematics, supplies the method.

Jede Handlung ist ein Versuch, einen weniger befriedigenden Zustand gegen einen befriedigenderen zu tauschen.

English translation: “Every action is an attempt to exchange a less satisfactory state for a more satisfactory one.”

Orthodox price theory, Kirzner charges, describes the properties of a final equilibrium while falling silent on the forces that would ever bring one about. His reconstruction redefines competition not as a market structure—a given number of firms facing flat demand curves—but as a process of entrepreneurial discovery. The entrepreneur here is neither capitalist nor innovator but the agent of alertness: the one who notices a price discrepancy, an unmet demand, or a cheaper method others have missed, and profits by closing the gap. From this vantage, monopoly becomes exclusive control of a resource rather than mere solitary selling, advertising becomes communication rather than waste, and profit becomes the sign that some prior ignorance has been overcome. Markets earn their defense as procedures that coordinate dispersed, fragmentary knowledge.

In equilibrium there is no room for the entrepreneur.

Monetary disorder, Hayek contends, is not an inherent flaw of capitalism but the predictable product of a state monopoly over money. Beginning with a modest proposal for Europe, free trade in currencies, the abolition of exchange controls, freedom to contract in any unit, he escalates into a general assault on sovereign coinage. Legal tender, he argues, is mere coercion; Gresham's law bites only where law fixes exchange rates; gold's discipline was institutional, never mystical. His constructive model is the privately issued ducat, held stable against a publicly announced commodity basket and policed not by convertibility but by competitive reputation and the customer's power to exit. Competition, rather than any monetarist quantity rule, becomes the procedure by which good money is discovered at all.

No authority can beforehand ascertain, and only the market can discover, the ‘optimal quantity of money’.

A broken promise may be morally wrong without warranting legal force; an established property title may conceal theft rather than deserve protection. These distinctions drive Murray N. Rothbard’s attempt to ground liberty in natural rights rather than economic efficiency. Starting from self-ownership and original appropriation, he asks which claims people may enforce against one another—and denies that public officials enjoy exemptions from the rules binding private persons. His defense of property consequently challenges inherited dispossession as well as taxation. The interest lies in testing how far these premises can carry a political ethics, especially where moral obligation and enforceable right diverge. This 1998 edition, with an introduction by Hans-Hermann Hoppe, presents an argument for a stateless order whose demanding implications extend beyond a conventional defense of markets.

Late in his life, Hayek returned to the question that had shadowed his career, whether socialism was, at bottom, a factual mistake rather than a moral one. His answer turns on knowledge: a central mind cannot command the dispersed information that only competitive prices, in the 'extended order' of human cooperation, can coordinate. Ranging across morality, property, trade, money, language, population, and religion, he argues that our rules of conduct sit between instinct and reason, neither designed nor innate, but evolved and selected because the groups that kept them flourished. He credits the marginal-utility revolution of Menger, Jevons, and Walras with explaining value as subjective and relational, dismantles the 'weasel word' social and the fraud of 'social justice', and holds that capitalism gave life to the proletariat rather than immiserating it. To imagine we designed civilization is the fatal conceit itself.

Not only is the idea of evolution older in the humanities and social sciences than in the natural sciences, I would even be prepared to argue that Darwin got the basic ideas of evolution from economics.

Peace did not restore the conditions of prosperity. In this 1864 study, Karl Theodor von Inama-Sternegg asks why the destruction of the Thirty Years’ War continued to depress German economic life after the fighting ended. His answer links ruined farms to impoverished towns: cultivators lacked workers and livestock, but also customers, credit, and security of tenure. Taxes, compulsory labour, guild restrictions, and territorial customs barriers could perpetuate losses that military violence had begun. Drawing on local chronicles and economic evidence, he traces these connections while acknowledging regional differences in recovery. Readers encounter an explanation of stagnation built around the interdependence of agriculture, manufacture, and trade—and a nineteenth-century liberal-national perspective whose commitments to productive freedom and political unity shape its account of German decline.

Could taxes paid in small purchases of bread, drink, and meat replace direct levies without burdening the poor or weakening trade? In this 1865 article, Karl Theodor von Inama-Sternegg examines how German advocates and critics of universal excise turned that proposal into a dispute over fiscal justice and political power. He takes Tenzel’s ambitious scheme seriously while tracing the objections that exposed its unequal burdens and administrative costs. For Inama-Sternegg, these disagreements helped establish principles of proportionality, legal certainty, and attention to taxation’s economic effects. Yet intellectual progress did not guarantee better government: rulers could adopt new consumption taxes without abolishing old levies. The article brings into focus the gap between a reform’s justification and its selective use to increase revenue.

What connects a constitutional state’s authority to the society it governs—and where should that authority end? In this 1867 article, Karl-Theodor von Inama-Sternegg approaches these questions through an organic account of social development. The first section traces legal consciousness, legislation and constitutional participation, making freedom the governing principle of the Rechtsstaat. The second turns to the relationship between economic life and political territory, drawing on the Germanic Markgenossenschaft to explore how expanding needs reshape communities and their boundaries. The argument offers a historical conception of law and statehood in which collective organization and individual personality must be reconciled. It invites readers to examine the connections between legal legitimacy, economic interdependence and political autonomy.

Territorial expansion can weaken a state; territorial loss can strengthen it. In this 1869 article, Karl Theodor von Inama-Sternegg challenges the equation of acreage and population with political power. He asks how much territory a state needs to sustain independence—and how much it can govern effectively. His distinctive approach brings markets, social cohesion and parliamentary representation into a discussion often dominated by military strength and geographical barriers. Mountains do not dictate borders, nor does a shared language settle nationality: their political significance changes with transport, commerce and institutions. The tension between economic integration and the independent existence of culturally distinctive small peoples gives the inquiry particular substance. Readers can discover an account of territorial limits that treats neither nature nor nationality as a substitute for political judgement and negotiated settlement.

Regulating the Danube could give Vienna room to grow—but would new land produce affordable homes or merely enrich landowners? In this 1869 pamphlet, Emil Sax argues that construction incentives cannot resolve housing distress while dense rental development drives up land values. His alternative joins early land acquisition, coordinated transport and utilities, and single-family homeownership in a privately operated undertaking under public oversight. The proposal’s economic reasoning is inseparable from its social commitments: Sax values healthier dwellings, but also domestic privacy and property ownership as supports for the existing social order. Readers can examine a concrete attempt to turn river engineering into housing reform, and the tension between its broad promise of relief and a settlement strategy in which wealthier households would move first.

Emil Sax treats the slum dwelling not as a mere symptom of poverty but as the mechanism by which poverty, disease, and moral ruin reproduce one another, which makes housing reform, in this 1869 Vienna treatise, the precondition of every other social reform. He begins with sanitation, linking damp, dark, overcrowded rooms to cholera, typhus, and child mortality, then argues that the good dwelling is a civilizing force restoring thrift, sobriety, and family order. Ownership he prefers to rent, the single-family cottage to the barracks, and planned worker colonies, Godin's Familistère at Guise foremost, to the mere patching of urban misery. Surveying employers, private capital, self-help building societies, and the state as agents of reform, he reads England's freer building trades and public sanitary legislation as jointly responsible for its sounder housing.

Die Gesetzgebung Englands bekennt sich zu dem Principe: schlechte Wohnungen werden von Staatswegen nicht geduldet.

English translation: “The legislation of England subscribes to the principle: bad dwellings are not tolerated by the state.”
