Friedrich August von Hayek, Our Moral Heritage (1983)

Hayek’s published lecture, followed by questions and discussion, explains the emergence of large-scale human cooperation through culturally selected moral restraints rather than rational institutional design. Its central problem is how people came to sustain an order extending beyond their knowledge, immediate relationships, and shared purposes. The lecture moves from an evolutionary account of morality through religion, property, and population growth to a critique of socialist redistribution. The discussion presses its implications for religious faith, moral justification, and the prospects of communism.

Hayek prefers “extended order” to “society” because the latter suggests that cooperation among strangers grows directly from fellow-feeling. He instead distinguishes instincts formed within small hunter-gatherer groups from acquired rules enabling cooperation among people who neither know one another nor pursue common ends. Traditional morality restrains the impulses appropriate to intimate communities, allowing people to respond to circumstances beyond their perception.

We are living in a society which exists only because we are capable of serving people whom we do not know, and even of whose existence we are ignorant; and we in turn constantly live on the services of other people of whom we know nothing.

The comparison with the evolutionary acquisition of vision makes morality an extension of practical reach: inherited rules permit adjustment to distant circumstances without direct awareness of them. Following Adam Smith, Hayek treats coordination beyond individual knowledge as the decisive achievement of civilization. His explanation explicitly departs from the utilitarian ethics he associates with his own early thinking and with Ludwig von Mises. Property, honesty, and the family did not prevail because people first understood their advantages.

We do not owe our morals to our intelligence: we owe them to the fact that some groups uncomprehendingly accepted certain rules of conduct—the rules of private property, of honesty, and of the family—that enabled the groups practising them to prosper, multiply, and gradually to displace the others.

Cultural selection, analogous to biological selection, supplies the explanatory mechanism. Groups practising certain rules expanded, transmitting those practices without comprehending their functions. This also explains, for Hayek, morality’s persistent unpopularity: successful restraints conflict with older impulses toward solidarity among known companions. His claim that civilization supports roughly two hundred times the population preceding it makes resistance to these rules a question of survival, not merely preference.

Religion answers a further difficulty: how could poorly understood restraints persist across generations? Hayek credits supernatural sanctions with preserving beneficial traditions. He distinguishes their civilizational usefulness from scientific truth and claims that enduring world religions support property and the family. His treatment of communism as a failing anti-property religion extends this selection argument into contemporary politics, although the lecture asserts these sweeping historical generalizations rather than systematically demonstrating them.

The economic section gives the evolutionary account a more specific mechanism. Hayek prefers “several property” because ownership can belong to groups as well as individuals. Separate domains of control enable the division of labour and the use of dispersed information. Increasing population can therefore increase specialization and productivity rather than necessarily generate diminishing returns. Against Malthus, Hayek argues that labour is differentiated, not uniform; following Smith, he links specialization to the extent of the market.

His demographic argument distinguishes declining average income from worsening conditions for existing individuals. Capitalism, he maintains, enables additional poor people to survive; their inclusion can lower the average without impoverishing those already present. He consequently interprets the growth of the proletariat as evidence of increased life-supporting capacity. Population growth is also presented as self-regulating: rapid multiplication occurs at the market economy’s “periphery,” where improved survival coexists with older family expectations. As market integration advances, Hayek expects that periphery to contract.

Government redistribution constitutes his stated exception. Subsidies can, he argues, sustain population growth where local conditions cannot support it, creating dependence and future misery. His example of the southern Sahara gives the argument a severe policy implication for development assistance. These claims remain predictions and assertions within the lecture, rather than conclusions established through comparative evidence.

The conclusion returns to coordination. Hayek presents socialism’s error as factual, not a disagreement over desirable ends: redistribution cannot be separated from the incentives and information that generate production. His criticism of John Stuart Mill targets the assumption that an existing social product can be distributed at will without affecting its future production.

The distribution of market rewards is the mechanism by which individuals are told what to do in order to make their maximum contribution to the total product.

The questions expose an unresolved issue: does cultural selection explain morality, or justify a particular moral code? Hayek does not fully resolve that distinction. Instead, he deepens his attack on the pride of institutional designers:

However, it was not man's intelligence which created society, but cultural evolution which created man's intelligence.

Learned traditions thus become conditions of reasoning itself, not simply objects reason can freely reconstruct. The discussion also qualifies his confidence about communism: he declines to predict events in Russia and grounds his optimism in an anecdote about a visiting scientist. The work’s significance lies in joining dispersed knowledge, cultural evolution, and demographic survival into a defence of inherited institutions. Its central tension is the movement from an explanation of institutional persistence to a warning that deliberate transformation would destroy the conditions sustaining modern populations.
