Between the Depression and the Deutsche Mark of 1948, the mark was destroyed a second time—and Sennholz, in this 1978 lecture, insists the destruction was political, not merely monetary. Nazi full employment after 1933 he grants as fact but reinterprets as coerced cost-cutting: unions abolished, wages frozen, and deficits disguised through special intermediaries issuing discountable bills. As the Reichsbank was subordinated and Schacht fell, wartime finance proved his central point—that inflation need not first appear as rising official prices. Rationing, price controls, and prosecutions defended posted prices while money surpluses fed black markets, hoarding, and substitute monies, the American cigarette emerging as a more honest currency than state fiat. The 1948 reform he judges ambivalently: it worked, he argues, only because Ludwig Erhard simultaneously abolished controls—proof that honest money depends on free exchange and property rights, not expert currency management.

No central bank can safeguard the currency from the inflationary expenditures of government.

Could a newspaper’s prolonged shutdown become a public benefit? In this brief 1979 letter to The Times, reproduced here in 2022, Friedrich August von Hayek endorses an editorial published as the paper resumed production after an industrial dispute. His approval turns on a condition: the newspaper must not merely learn from its difficulties but persist in teaching their lessons. The accompanying editorial note identifies the reform programme he was endorsing—greater productivity, technological change and restrictions on trade unions’ legal immunities. The letter offers a compact glimpse of Hayek’s support for turning an institution’s own experience of conflict into sustained public advocacy, without developing a separate argument about union power.

Is pure entrepreneurial profit won by sheer luck, or by a superior ability that markets ought to price like any other factor? Presented in an American Economic Association session, this chapter refuses both horns. Profit exists only where the same or economically equivalent good is valued inconsistently—where Jevons's Law of Indifference has not yet been fulfilled—and competition steadily grinds it away. Kirzner works the puzzle through Robinson Crusoe: true "Crusonian" profit appears not in windfalls or in the mechanical conversion of means into ends, but when Crusoe discovers he had misvalued his own time, seeing boat-building as suddenly worth more than catching fish by hand. Menger's Law then reimputes that value and the profit fades. Alertness, he concludes, is no resource hired in advance, so profit is not a marginal-productivity return.

With complete knowledge, pure profit is impossible.

A commercially sophisticated tradition, fluent in the language of projectors, undertakers, and speculators, nonetheless denied the entrepreneur any distinct place in its theory—this is the puzzle the essay sets out to solve. English classical economics, Kirzner argues, submerged the entrepreneurial role into that of the capitalist, treating profit as a return on stock varying with capital advanced rather than with alertness or judgment. Adam Smith is the decisive case: even his self-employed Scottish pebble-gatherers earn only "wages," where Cantillon had already seen undertakers bearing uncertainty. Kirzner canvasses the explanations—the fusion of owner and manager in British firms, the wage-fund doctrine, Smith's tidy triad of wages, rent, and profit—and locates the deepest in the classical hunger for long-run natural prices, which makes speculation and discovery appear merely accidental.

The price at which the contract was valued was fixed and the entrepreneur bore the risks of profit and loss from the bargain.

Because economists model choice as maximization among given alternatives, they narrow freedom to a matter of execution—whether the agent can reach the optimum the data already imply. Kirzner's essay recovers the dimension they miss: liberty is not merely the power to attain ends already fixed, but the entrepreneurial freedom to discover which ends, means, and opportunities exist at all. Drawing on Mises, Shackle, and Lachmann against the Robbinsian model, he shows how freedom collapses into mere power once ends are treated as data. The argument answers Stigler's demand that critics of the expanding state name the liberties it has actually impaired: some losses stay invisible precisely because they suppress the discovery of what might have been chosen. Restriction's deepest harm, echoing Hayek's knowledge problem, is epistemic—it numbs alertness.

A free society is one in which individuals are free to discover for themselves the available range of alternatives.

Nozick's entitlement theory defends the market on a single word: transfers are just because they are voluntary. Kirzner accepts the framework but presses a difficulty Nozick never faces—real markets are not states of equilibrium knowledge but processes of correction, and entrepreneurial profit is earned precisely by noticing what a trading partner has missed. If a seller would not have dealt on the same terms under fuller awareness, his ignorance seems to corrupt the voluntariness on which the whole defense rests. Kirzner's answer joins an ethical judgment to an economic one: a "finders-keepers" ethic together with the insight that discovering a good's unnoticed use can amount to creating a new dimension of value. So construed, entrepreneurial gain is not extracted from the seller but brought into being—while fraud and coercion remain excluded from just transfer.

Our discussion has pointed out a third possibility: a thing may be held as the result of the holder having, in the relevant sense, created it ex nihilo, by finding it.

Should the ruin of fiat inflation ever open a path back to gold, Hazlitt argues in this 1979 essay, that path must not lead back to the nineteenth-century fractional standard but to a full 100 percent reserve. Fractional reserves, in his account, are not a clever economy on scarce gold but the very flaw that destroys every gold standard: they let banks pile multiple claims on a limited base, lower interest rates artificially, and finance booms that must end in liquidation. He tracks the pattern through the Federal Reserve's layered credit pyramid, dismisses the notion of self-liquidating business loans, and stages the open-economy version in an imagined Ruritania whose credit expansion drains its gold. The result fuses Austrian trade-cycle theory with a demand for monetary constitutionalism.

In short, the fractional gold standard tends almost inevitably to become more and more attenuated, and while it does so it permits and encourages progressive inflation.

For decades economic theory fixed its gaze on equilibrium conditions while ignoring the process by which markets actually move toward them. Recovering a neglected strand of Hayek's work from the 1930s and 1940s, Kirzner argues that the tendency toward equilibrium is nothing other than a process of learning: participants discover one another's plans, notice their own errors, and revise bids and offers accordingly. He weighs Walrasian tatonnement, Hicksian adjustment, and Samuelsonian stability analysis and finds each assumes away the auctioneer, the price change, and the dispersion it should explain. Competition becomes a discovery procedure rather than a static condition, and Hayek's critique of socialist calculation stands revealed as continuous with his critique of static economics. Where Hayek treats equilibration as an empirical matter external to theory, Kirzner grounds it in Misesian entrepreneurial alertness.

The process whereby the market is understood to move from disequilibrium toward equilibrium is, it follows, to be similarly perceived in terms of knowledge.

Thought is the only thing directly known, and its passing is the raw experience from which time itself is abstracted—an unlikely starting point for a theory of choice, and a deliberate one. Shackle builds from it a critique of deterministic economics: if choice genuinely matters, it must be a beginning, an uncaused cause, a taking-place not already implicit in its antecedents, and its sequels cannot be a ready-made list waiting to be ranked. Possibility, for the chooser, becomes the absence of discernible fatal obstacles rather than a measurable frequency; commitment, not calculation, is the vital act, staking self-esteem on imagined outcomes. Marshalling potential surprise, ascendancy, and focus-gain against frequency probability, he makes investment the exemplary economic act—a symbolic wager on a future whose outcomes can never be exhaustively listed.

Possibility, for the chooser, is the absence of discernible fatal obstacles.

Push subjectivism to its limit and a paradox appears: the most important economic knowledge may be knowledge whose very existence no one suspects. Building on Hayek, Shackle, and Boulding, Kirzner distinguishes the deliberate, cost-conscious search of Stiglerian information economics from spontaneous discovery, the unbidden noticing that comes through perception, conversation, advertising, or accident. Search, he insists, presupposes what it claims to explain, since one must already know enough to know what is worth looking for. The failure to notice an opportunity available for the taking he names a lack of entrepreneurial alertness, and he judges institutions by how well they translate overlooked possibilities into profit that alert actors will seize. The market thus coordinates not merely by economizing on known information but by stimulating learning no one ever set out to acquire.

When we discuss the ways people acquire knowledge, we refer to the ways they acquire the opinions and views, doubts and guesses, as well as certainties, that account for their actions.

Robert Nozick's Anarchy, State, and Utopia had revived the case for a state confined to protecting against force, theft, fraud, and broken contracts — and Hazlitt's review both cheers the destination and quarrels with the road to it. He accepts Nozick's derivation of a minimal state from competing protective associations, and admires the entitlement theory that treats holdings as the historical residue of labor, exchange, gift, and inheritance rather than a central stock for the state to pattern. But he rejects the natural-rights scaffolding beneath it, judging natural law too contradictory to ground politics, and offers a rule-utilitarian defense instead: rules against violence and fraud are justified because their general observance makes cooperation possible. Brilliant against anarchism and Marxian exploitation, the book strikes him as digressive and, by its author's own admission, unfinished.

Two noteworthy implications are that the state may not use its coercive apparatus for the purpose of getting some citizens to aid others, or in order to prohibit activities to people for their own good or protection.

Since its absorption of Walrasian influence, modern microeconomics has left almost no room for the entrepreneur, yet the Austrian line descending from Menger kept market process at its heart. Does the founder himself already hold the theory his successors built? The answer here is scrupulously balanced. Menger treats entrepreneurial activity as a higher-order service of information, calculation, will, and supervision, close to a hired manager's, and his economics is saturated with knowledge, error, uncertainty, and the spontaneous emergence of money. But when Menger builds price theory he excludes error as pathological and lets prices settle instantaneously, so his economic prices describe fully informed economizing rather than discovery. The subjective-value revolution, Kirzner suggests, so absorbed Menger that he never saw the market as a discovery process, a gap Mises and Hayek would later close.

This does not, at least without further extension, imply that a systematic process of adjustment exists in the market, set in motion and fueled by continual entrepreneurial discovery.
