Elections can replace rulers peacefully without securing independence from their power. This distinction anchors Hans F. Sennholz’s 1956 essay, contributed to the volume honoring Ludwig von Mises. Against communist promises of emancipation through collective ownership, Sennholz argues that nationalized production makes individuals dependent on administrators. But his defense of Western democracy is conditional: subsidies, protectionism, and redistribution, he contends, turn economic cooperation into competition for political favors. Agricultural price supports give this argument concrete institutional substance, showing how organized beneficiaries can prevail over a dispersed public. Readers encounter a market-liberal account of democracy that locates its value in peaceful political change, while asking whether that achievement can endure when government increasingly controls livelihoods and economic opportunity.

Specialization is indispensable to serious inquiry and, in the study of society, uniquely dangerous, and that is the tension this lecture-essay sets out to hold. A physicist may work fruitfully within a narrow technical field, but the student of society who masters only one discipline may misunderstand the very world he examines, since concrete social problems draw on law, economics, history, anthropology, philosophy, and inherited cultural wisdom at once. Hayek distinguishes systematic specialization in a theoretical field, which trains rigor, from topical specialization around an empirical object, which mature work demands; the danger lies in sequencing, for breadth without discipline becomes amateurism while discipline without breadth becomes blindness. He couples this with his anti-rationalist caution against discarding traditions whose significance we cannot yet articulate, and proposes settings, such as a College of Advanced Human Studies, where disciplines can meet after competence is won.

But nobody can be a great economist who is only an economist—and I am even tempted to add that the economist who is only an economist is likely to become a nuisance if not a positive danger.

Conceived as an introduction to The Free Man's Library, this 1956 essay pairs a bibliography of individualist and classical-liberal writing with a warning about how easily its lessons are forgotten. Hazlitt's target is the modern progressive who champions freedom of thought and speech while dismantling economic liberty, not seeing that the two cannot be separated. He reclaims the word liberal for Adam Smith, Bastiat, Cobden, and Herbert Spencer, sets historic liberalism's Rule of Law against the drift toward planning and bureaucracy, and quotes Hamilton to the effect that power over a man's subsistence is power over his will. The essay's provocation is its final inversion: the intelligent conservative, defending inherited liberties against expanding state power, has become the truer heir of the liberal tradition.

Liberty is a whole, and to deny economic liberty is finally to destroy all liberty. Socialism is irreconcilable with freedom.

Even sympathetic critics concede that market allocation may be efficient while inherited wealth renders its results unjust—unless the state periodically redistributes. That concession is the target here. The mistake, Lachmann argues, lies in treating the distribution of wealth as a fixed datum rather than a continuously revised outcome of the market process. He separates the two senses of 'datum'—something merely observed at an instant, and an independent determinant in equilibrium theory—and denies wealth the second role. Because capital goods are heterogeneous and their value hangs on complementarities discovered only under change, the market itself redistributes through capital gains and losses, passing wealth to those quicker to read new scarcities. The result is Pareto's circulation of elites: a leveling process, a game of skill rather than chance, in which no class of owners—shareholder or bondholder—escapes revaluation.

The owners of wealth, we might say with Schumpeter, are like the guests at a hotel or the passengers in a train: They are always there but are never for long the same people.

To ask an economist for the date a boom will break is to ask for the one thing economics cannot deliver—yet businessmen, knowing an artificial boom must end, press for exactly that. The monetary theory of the cycle is 'irrefutable,' Mises grants in this 1956 essay: forcing interest rates below their market level through bank credit distorts production and guarantees an eventual depression. But economics is qualitative, not quantitative; it can say the boom will not last, never precisely when it will break, for human action offers none of the constant relations natural science exploits. Statistics only describe the past. And a correct public forecast would annul itself—if everyone believed it, they would sell at once and bring the crash forward on the spot.

At the very instant this forecast was uttered and accepted as correct, the crisis would already be consummated.

Only actual choice reveals preference, and only at the instant it is made — this principle of 'demonstrated preference' is the lever with which Rothbard rebuilds utility and welfare economics. Utility is ordinal, never measurable; he rejects both Samuelson's revealed preference, which smuggles in stable orderings across time, and the indifference curves of Hicks and Allen, since indifference is never enacted in action. Turning to welfare, he grants that economics can make no interpersonal utility comparisons, then shows that voluntary exchange itself demonstrates mutual gain: each party acts to benefit, so the free market raises social utility without measurement. Coercion reverses the verdict. Because the state rests on taxation, which injures some against their demonstrated consent, no government act can be shown to raise social utility — a conclusion he presses against democratic consent, public goods, and the free-rider argument.

Individual valuation is the keystone of economic theory.

Stable money requires coordination—but how much coordination can coexist with economic freedom and central-bank independence? In this 1956 article, Richard Kerschagl rejects both a simple return to gold-standard automaticity and confidence in monetary technique alone. His distinctive emphasis falls on what credit finances, how quickly investment yields output, and whether private saving and capital formation can sustain productive capacity. Interest-rate changes and open-market operations thus appear as instruments whose effectiveness depends on institutions they cannot themselves create. His comparison of Soviet and American arrangements sharpens the tension between controlling purchasing power and preserving freedom in the use of money. Readers can discover why, for Kerschagl, currency stability demands cooperation across economic policy while also requiring protection from government financing needs.

How could the Zeitschrift für Nationalökonomie preserve its founding aims while rebuilding international scholarly exchange after wartime disruption? In this brief 1956 editorial notice, Alexander Mahr addresses that practical question as the journal’s new editor following Hans Mayer’s death. The appointments of Gottfried Haberler and Oskar Morgenstern connect earlier affiliations with hopes for closer contact with Anglo-American economics; plans to reprint unavailable articles and index earlier volumes give continuity a concrete editorial form. Rather than an appraisal of Mayer’s thought, the notice offers a compact record of how Mahr proposed to carry the journal forward through renewed collaboration and access to its past.

Automation can lower production costs without lowering prices—and make factories more efficient while leaving them more dependent on manufactured demand. In this 1956 article, Hans Bayer examines that tension through the capital requirements and rigidity of automated production. He connects the need for assured sales to industrial concentration, advertising, and products designed for premature replacement. His distinctive measure of economic progress is neither profitability nor technical sophistication, but the durable material basis for personal development. From this perspective, disputes over wages, ownership, and shorter working hours become questions about who receives automation’s benefits and who controls its purposes. The article shows why, for Bayer, greater productive capacity cannot by itself resolve the conflicts between production and consumption, economic power and individual freedom.

Monetary policy can change the stock of money without determining how rapidly it circulates—or how much spending follows. This gap anchors Josef Herbert Fürth’s 1957 review of the second edition of J. Zijlstra’s study of monetary velocity. Fürth credits Zijlstra with clarifying neoclassical concepts and recovering neglected contributions, but asks what logically sound reasoning achieves without factual support. His pointed criticism concerns the book’s neglect of postwar national accounting and flow-of-funds research, especially work undertaken in the Netherlands itself. This brief review makes a precise distinction between clarifying monetary theory and explaining how policy works: velocity is not merely a term in an equation, but a crucial link between changes in money holdings, expenditure, and the flow of goods.

Who bears the cost of investment: voluntary savers, or workers whose real wages fall as prices rise? Walter Froehlich’s review of Erich Preiser’s collected essays makes this distributional question central to his assessment of their economic reasoning. He values Preiser’s careful separation of monetary from real relations and underemployment from full employment, while resisting claims of novelty for arguments already familiar in American literature. His discussion also shows how property ownership enters theories of distribution through concrete market conditions: workers with land need not respond to low wages as propertyless workers do. This short review offers a measured encounter with Preiser’s formulations, distinguishing explanatory clarity from theoretical innovation and tracing the social assumptions within apparently technical accounts of saving, investment, and income.

Land cannot be manufactured, but does its fixed supply make ownership economically passive? In this reply to Georgist critics, first distributed in 1957 and reprinted here in 2011, Murray N. Rothbard uses an unexpected comparison—land and Rembrandt paintings—to challenge the case for taxing away land rent. Both assets are scarce; neither, he argues, allocates itself to users without owners’ judgment and incentives. His Austrian account of capitalization and entrepreneurial foresight gives the dispute a concrete focus: what happens to site allocation, assessment, and long-term improvements when owners lose their returns? The ethical defence is more qualified than a blanket endorsement of existing titles: Rothbard defends first use and subsequent transfer, not conquest. The reply exposes the distinct economic and moral premises on which his opposition to Georgism rests.
