When general terms like 'planning,' 'social,' and 'positive' are narrowed into political slogans, the same fate threatens 'rationalism' itself, and it is that word Hayek sets out to rescue in this 1965 lecture, delivered in Japan and reprinted here. His quarrel is not with reason but with what he names rationalist constructivism: the Cartesian conceit, running from Bacon and Hobbes through Descartes to Rousseau, Hegel, and Marx, that useful institutions must be deliberately invented and remade from explicit premises. From this hubris, he argues, all modern socialism, planning, and totalitarianism derive. Against it he sets a modest, critical tradition of Hume, Smith, Menger, and Popper, in which reason is itself a product of evolved civilization, transmitted through language and unarticulated rules, and freedom under law becomes an instrument for using knowledge no single mind commands.

Reason is like a dangerous explosive which, handled cautiously, will be most beneficial, but if handled incautiously may blow up a civilization.

Keynes made an unforgettable impression even on those who could never accept his monetary theories, and Hayek, friend since their 1928 meeting and sparring partner after his 1931 move to London, begins here in that key of admiration. But recollection turns to reckoning. Recalling his laborious review of the Treatise on Money, only for Keynes to change his mind, Hayek explains why he never mounted a comparable assault on the General Theory, and locates his true objection not in any detail but in the whole macroeconomic approach. The Keynesian Revolution's lasting effect, he contends, was to elevate measurable aggregates over the relative prices and capital structures through which an economy actually coordinates, encouraging a sophisticated inflationism by assuming resources everywhere lie unused. He predicts the episode will one day appear a temporary aberration.

But the assumption that all goods and factors are available in excess makes the whole price system redundant, undetermined and unintelligible.

Freedom, on this account, depends far less on who holds power than on how far power may reach. Reconstructing classical liberalism as a theory of law-governed order, Hayek separates the English Old Whig tradition of Hume, Smith and Acton from the Continental constructivism he traces to Rousseau and the French Revolution, and insists that liberalism and democracy answer entirely different questions. He renames the market a catallaxy to dispel the fiction that society is one great household with shared ends, grounds liberty in private property and general rules of just conduct, and dismisses 'social' or distributive justice as nonsense in an order where no one distributes. First delivered to the Mont Pelerin Society in 1966, the paper closes on the three great negatives that must govern all coercion: peace, justice and liberty.

Liberalism and democracy, although compatible, are not the same. The first is concerned with the extent of governmental power, the second with who holds this power.

Notorious in his own century as a satirist who declared private vices public benefits, Bernard Mandeville is recovered here, in the German translation of Hayek's 1966 British Academy lecture, not as an economist but as a profound psychologist of human nature. The scandalous paradox of The Fable of the Bees, Hayek argues, is the lesser insight; the greater is that complex social order arises from actions that pursue private aims while intending none of the larger outcomes they produce. Mandeville thus becomes an early theorist of spontaneously grown institutions, law, morality, language, money, markets, against the seventeenth-century rationalism of Descartes and Hobbes. The essay traces a line of descent from Mandeville through Hume and Adam Smith to Ferguson's formula about results of human action but not human design, and onward to Darwin.

Ich befürchte, die meisten Zeitgenossen von Bernard Mandeville würden sich im Grabe umdrehen, wüßten sie, daß er der Britischen Akademie inzwischen als »master mind« gilt.

English translation: “I fear that most of Bernard Mandeville's contemporaries would turn in their graves if they knew that he is now regarded by the British Academy as a "master mind".”

Hayek draws a distinction that, once stated, seems obvious yet is constantly confused: the rules an individual follows are not the same thing as the order of actions that emerges when many follow them. A rule may be innate or learned, genetic or cultural, and need never be consciously known; what natural selection tests is not the isolated rule but the viability of the whole group order it helps sustain. Moving from the flight patterns of geese and insect division of labour to kinship, property, and succession, he shows coordination arising without any actor grasping the design. He calls the theoretical reconstruction of such processes conjectural history, aligns social science with biology and geology rather than mechanics, and, invoking Mandeville, Hume, and Smith, defends explanation by function without any designing purpose.

Norms are thus an adaptation to a factual regularity on which we depend but which we know only partially and on which we can count only if we observe those norms.

Behind the single German word Rechtsordnung, Hayek finds two things habitually run together: the order of legal rules and the Handelnsordnung, the order of actions that arises when people follow them. Written in German across twelve sections, the essay defines order as a factual relation among recurring elements that lets us form reliable expectations from partial knowledge, with no ordering will required. The market is his central case: it solves the problem of using more knowledge than any single mind possesses, adjusting through prices by what he calls, borrowing from cybernetics, negative feedback. From this he mounts a sustained assault on 'social' justice, on Carl Schmitt's concrete-order thinking, and on the welfare state's drift from private-law rules toward public-law command, arguing that only human conduct, never an unintended outcome, can be called just or unjust.

Gerecht oder ungerecht kann nur menschliches Verhalten oder dessen beabsichtigte Ergebnisse sein, aber nicht eine bloße Tatsache, die niemand absichtlich herbeigeführt hat oder herbeiführen könnte.

English translation: “Only human conduct, or its intended results, can be just or unjust, but not a mere fact that no one has intentionally brought about or could have brought about.”

The separation of powers, the founders' chosen guard for liberty, has failed, hollowed out, Hayek argues, once law came to mean whatever a legislature enacts rather than a particular kind of rule. First published in Il Politico, this essay locates the deeper error in the doctrine of sovereignty: the assumption that ultimate power must be unlimited because power can be checked only by another power. Against Rousseau, legal positivism, and unlimited majority rule, he revives the distinction between law as an abstract rule of just conduct and command aimed at chosen outcomes. His remedy splits the assembly in two, a partisan governmental chamber for services and budgets, a nonparty lawmaking chamber for universal rules, and, illustrating the design through taxation, names the result demarchy.

In the last resort it rests on the misconception that the ultimate ‘sovereign’ power must be unlimited, because, it is thought, power can be checked only by another power.

Between the natural and the artificial, Hayek argues, lies a third and decisive category that Western thought has persistently missed: the institutions and rules that are the result of human action but not of human design. Markets, customs, language and law belong there, neither given by nature nor invented by any mind. Tracing the insight through Mandeville, Montesquieu, Hume, Ferguson and Smith to its revival in Carl Menger, he turns it against legal positivism, which mistakes law for the mere command of a legislator and so severs it from justice. Law, he counters, is older than legislation; justice is discovered by testing rules for compatibility within an inherited order, never deduced from pure reason nor invented by sovereign will.

There never has been and there never can be a ‘gap-less’ (lückenlos) system of formulated rules.

Textbook models of perfect competition assume away the very thing real markets accomplish: because they presuppose that all relevant facts are already known, they make rivalry look wasteful and pointless. Hayek turns the objection around, arguing that competition earns its keep precisely as a discovery procedure, a way of eliciting information about scarcities, uses, and capacities that no participant or planner holds in advance. He reframes the market not as an economy governed by a single ranking of ends but as a catallaxy, a self-correcting order steered by negative feedback and price signals, whose value can be judged only by comparing societies rather than by predicting particular outcomes. Along the way he defends pattern prediction, rejects the language of equilibrium, and warns that incomes policy freezes adjustment exactly when circumstances demand movement.

But which goods are scarce goods, or which things are goods, and how scarce or valuable they are – these are precisely the things which competition has to discover.

Inherited words—order, law, economy, democracy—make spontaneous social orders look like purposive organizations, and this 1968 essay in political semantics sets out to break their spell through a series of paired corrections: Kosmos against Taxis, spontaneous order against made arrangement; Nomos against Thesis, the universal rule of just conduct against the organizational command; Katallaxie against Wirtschaft, the market as a discovery procedure against the household writ large; and finally Demarchie against Demokratie. Only a Kosmos, Hayek insists, can sustain an open society among strangers who share no concrete ends, so 'social' or distributive justice—the justice of an organization—loses all meaning where no one distributes the results. The tract anticipates Law, Legislation and Liberty, turning the reform of language into a servant of liberal constitutionalism.

Wir wünschen die Meinung der Mehrheit als letzte Autorität, aber wir wollen nicht dulden, daß die nackte Gewalt der Mehrheit den einzelnen regellos Gewalt antut.

English translation: “We desire the opinion of the majority as the ultimate authority, but we do not want to tolerate that the naked power of the majority does violence to the individual in a rule-less manner.”

How can strangers who share no common purpose live together in peace? Not, this short lecture answers, by organizing them around shared aims, but only when they obey the same abstract rules while pursuing different ends. Hayek traces the passage from tribal closure, bound by common purposes, to the open Great Society, whose achievement is to generate order spontaneously and merely to furnish each individual with opportunities rather than prescribe his goals; Roman law and Christianity figure as forces that turned tribal rules into universal ones. The rules such a society needs are mainly negative, delimiting coercion rather than commanding ends—and the same principle, extended outward, is for Hayek the only real foundation of international peace, which no multiplication of international bodies can supply.

Die große Errungenschaft der offenen Großgesellschaft besteht darin, daß sie spontan Ordnung hervorbringen kann, dadurch daß die Individuen abstrakten Regeln gehorchen, das heißt, daß sie eine sich selbst bildende Ordnung ist.

English translation: “The great achievement of the open Great Society consists in its being able to bring forth order spontaneously through the fact that individuals obey abstract rules—that is, that it is a self-forming order.”

Political thought stumbles because everyday language fuses what must be kept apart: grown orders with designed organizations, law with command, popular opinion with unlimited collective will. Presented here in translation of Hayek's 1967 essay, the lecture threads seven paired distinctions to clear the confusion, cosmos and taxis, nomos and thesis, articulated and non-articulated rules, opinion and will, nomocracy and teleocracy, catallaxy and economy, demarchy and democracy. A cosmos serves no single purpose and can marshal knowledge dispersed beyond any mind; a taxis is imposed toward chosen ends. Because a spontaneous order allocates nothing, social justice can have meaning only inside an organization. From these terms Hayek rebuilds liberal constitutionalism, proposing demarchy, popular authority over universal rules but not over particular outcomes, as the cure for factional, unlimited majority power.

The insight that not all order that results from the interplay of human actions is the result of design is indeed the beginning of social theory.
