This file is a single 1983 Zürich lecture. Hayek presents a compressed prospectus for the project that would become The Fatal Conceit: a defense of the evolved moral conditions of the market order against rationalist constructivism and socialism.
Es ist, und dies mag Sie zunächst überraschen, im wesentlichen eine Studie über die Rolle der Ethik und der Moral in der Bestimmung unserer Gesellschaftsordnung.
English translation: It is—and this may at first surprise you—essentially a study of the role of ethics and morals in determining our social order.
The lecture’s organizing question is not whether morality can be deduced from reason, but whether its origin and function can be studied scientifically. Hayek shifts ethics from justification to genealogy and consequences.
Diese Fragen lauten: Wie ist unsere Moral entstanden und was hat sie für uns getan?
English translation: These questions are: How did our morality arise, and what has it done for us?
Against the modern assumption that morals come only from instinct or deliberate reason, Hayek inserts a third source: inherited tradition. This is his central conceptual move. Moral rules, especially those protecting private property and the family, are not transparent products of rational design; they are practices that survived because groups observing them could sustain larger, more complex forms of cooperation.
The argument then widens into an intellectual history of evolution. Hayek denies that evolutionary explanation belongs originally or exclusively to biology. He traces it to law, language, Roman jurisprudence, German historicism, and the Scottish Enlightenment, especially Hume, Smith, and Ferguson. Evolution and spontaneous order are, for him, inseparable problems wherever complex institutions exceed conscious design.
Die Vorstellung von Entwicklungsgesetzen, die annimmt, daß bestimmte voraussehbare Phasen aufeinanderfolgen müssen – eine Idee, die im übrigen von Hegel und Marx stammt – hat mit der Theorie der Entwicklung und der Kultur überhaupt nichts zu tun.
English translation: The notion of laws of development, which assumes that particular predictable phases must succeed one another—an idea that, incidentally, stems from Hegel and Marx—has nothing whatever to do with the theory of evolution and of culture.
This rejection of “laws of development” separates Hayek both from Marxist historicism and crude social Darwinism. Cultural evolution differs from biological evolution because it depends on the transmission of acquired rules and on group-level effects. Yet both involve selection: rules endure when they help the groups that practice them survive, grow, and coordinate better.
Die Entwicklung der Moral ist ein Anpassungsprozeß und nicht, wie die rationalistischen Theoretiker glauben, ein Ergebnis bewußter menschlicher Entscheidung.
English translation: The development of morality is a process of adaptation and not, as rationalist theorists believe, the result of conscious human decision.
The most provocative part of the lecture is Hayek’s treatment of property, family, and religion. He argues that these institutions were preserved not because humanity understood their function, but because religious sanctions protected rules whose social utility was opaque. Religion, in this account, carries “symbolic truths”: not scientific propositions, but supports for practices that made civilization possible.
Unsere Moral können wir gar nicht rational rechtfertigen, weil wir ja nicht wissen, was sie für uns getan hat.
English translation: We cannot rationally justify our morality at all, because we do not know what it has done for us.
Hayek’s defense of tradition is therefore not simple conservatism. It is an epistemological claim: social orders depend on rules that encode more knowledge than any mind can articulate. The rationalist intellectual, demanding explicit justification, is tempted to discard precisely those restraints that make extended cooperation possible.
Es war nur mit dieser Methode möglich, eine Moral zu erhalten, die uns so sehr half, aber die wir doch nicht verstanden.
English translation: It was only by this method that it was possible to preserve a morality which helped us so greatly and yet which we did not understand.
A middle section applies this evolutionary argument to population. Hayek rejects the Malthusian fear that population growth necessarily impoverishes societies, while allowing special cases where externally supported growth may become destructive. His broader point is that expanding populations can intensify division of labor and differentiation of talents.
Die Bevölkerungsvermehrung war, abgesehen von solchen tragischen Spezialfällen, niemals Ursache einer Verarmung.
English translation: Population growth has, apart from such tragic special cases, never been a cause of impoverishment.
The conclusion returns to the market as a knowledge system. Property-based morality matters because it enables people to act on dispersed facts they do not and cannot centrally know. Prices do not merely allocate given resources; they tell individuals what information to seek and how to contribute to a coordination process beyond any planner’s survey.
Was die Sozialisten nie verstanden haben und die heutigen Sozialisten kaum je verstehen werden, ist, daß der Markt deshalb so unerhört wichtig ist, weil er uns in die Lage versetzt, individuell verstreutes Wissen zu nutzen und vor allem all den Individuen zu sagen, wonach sie suchen müssen, um damit den größten Beitrag zum Sozialprodukt zu leisten.
English translation: What the socialists have never understood, and what today's socialists will hardly ever understand, is that the market is so tremendously important precisely because it enables us to make use of individually dispersed knowledge and, above all, to tell each individual what he must look for in order to make the greatest possible contribution to the social product.
The lecture’s relevance lies in this fusion of moral theory, institutional evolution, and economic epistemology. Hayek argues that socialism fails not only because it misallocates resources, but because it misunderstands how civilization itself is carried by evolved rules, price signals, and traditions that no central intelligence invented or can replace.
