Booksology The idea of a “golden age” is very old. The origin of the phrase likely dates to Hesiod, in his eighth century B.C. Works and Days (translated by Hugh G. Evelyn-White, in Hesiod: The Homeric Hymns and Homerica (Harvard University Press, 1914)), where he said:
(T)he deathless gods who dwell on Olympus made a golden race of mortal men who lived in the time of Cronos when he was king in heaven. And they lived like gods without sorrow of heart, remote and free from toil and grief: miserable age rested not on them; but with legs and arms never failing they made merry with feasts beyond the reach of all evils. . .the fruitful earth unforced bore them fruit abundantly and without stint. (Lines 109–120)
But the story of the world is decline and decay, and so it was with the Golden Age; mankind became silver, then bronze; then heroes lived in the fourth age, but they too declined, into iron:
Would that I were not among the men of the fifth generation, but either had died before or been born afterward. For now truly is a race of iron, and men never rest from labor and sorrow by day, and from perishing by night; and the gods shall give them grievous cares. (Lines 174–79)
This is the classical view of the world, where the best human condition lies in the past, and history is a process of moral and material degeneration.
This conception of the world, and history, lasted more than two thousand years, through the Middle Ages, nearly unquestioned. But two great intellectual movements crumbled its foundations. The Renaissance was based on the belief that a “rebirth” of classical excellence, and more, including advances in science, was all possible. And the Enlightenment burst out into the world with radical ideas that science and a new conception of man would actually result in progress, and improvement: our best days lay ahead of us, not behind.
But the Golden Age view of history has not been entirely defeated. There are two traditions contesting the conception of society: One holds an optimism about the possibility—even inevitability—of “progress.” This characterizes Adam Smith, Immanuel Kant, G. W. F. Hegel, J. S. Mill, and Karl Marx; Steven Pinker, a modern avatar.
The opposition, the claim that while there may be a secular trend toward progress each civilization tends toward decline, was galvanized by Edward Gibbon. Gibbon’s Decline and Fall of the Roman Empire revived the classical conception, but with a more modern method. He followed a single civilization, Rome, through its decline, marshalling massive documentary evidence. The motor of decline was institutional change, operating through increasing problems with the military, and pathologies in tax policies and incentives. Gibbon changed the classic view (“Rome fell because men declined”) into what we would now recognize as a social science-based comparative statics argument: “Rome fell because institutions changed incentives.” A number of modern authors, including most prominently Mancur Olson, have taken up this approach and applied it fruitfully in new contexts.
Johan Norberg’s Peak Human enters a crowded but deeply unsettled field, focusing on explaining the fragility of progress and the evanescence of great societies. In recent decades, scholars and popular writers alike have oscillated between triumphalist narratives of liberal modernity and gloomy predictions of civilizational collapse. Norberg rejects both impulses. His book advances a more demanding thesis: human progress is neither illusory nor inevitable. It occurs in distinct historical “golden ages,” each marked by extraordinary creativity and growth, and each terminated not by accident but by endogenous political and institutional forces.
Norberg’s core contribution is to insist that the institutional arrangements that generate prosperity—openness to trade, toleration of dissent, security of property, and intellectual pluralism—are not self-reinforcing equilibria. On the contrary, they are politically unstable achievements, continually threatened by the very success they produce. In this respect, Peak Human belongs to the tradition of “rise and decline” theories associated with Edward Gibbon and Mancur Olson, yet it also departs from both in important ways. Norberg is less fatalistic than Gibbon and less mechanistic than Olson, while nonetheless sharing their skepticism toward teleological accounts of history.
To see the distinctiveness of Norberg’s argument, it is useful to situate it against two rival traditions that continue to shape how economists and historians think about progress: the stadial theory of the Scottish Enlightenment and Hegelian philosophies of historical development.
The Scottish Enlightenment offered what might be called a developmental account of institutions. Thinkers such as Adam Smith, Adam Ferguson, and John Millar described societies as passing through successive stages—hunting, pastoral, agricultural, and commercial—each characterized by distinctive forms of property, law, and governance. Although these authors were attentive to corruption and moral decay, the underlying framework was broadly progressive. Institutions adapted to changing material conditions, and those adaptations generally improved the scope for peaceful exchange and cooperation among strangers.
What matters for Norberg’s argument is not whether the Scots were “right,” but the implicit optimism embedded in their framework. Commercial society, once achieved, appeared relatively robust. Markets, legal systems, and norms of trust evolved together, creating a self-supporting architecture of prosperity. Decline, when it appeared, was often attributed to moral failings—luxury, complacency, loss of civic virtue—rather than to any inherent instability in the institutional order itself.
Norberg’s historical evidence challenges this presumption. Across cases as diverse as classical Athens, Abbasid Baghdad, Song-era China, Renaissance Italy, and the Dutch Republic, he finds not merely moral decay but deliberate institutional closure. Trade routes are restricted, heterodox thinkers suppressed, monopolies entrenched, and political authority centralized. The pattern suggests not a failure to complete the march of progress, but a conscious retreat from openness once prosperity has raised the stakes of control.
If the Scottish Enlightenment offers a modestly optimistic developmental story, Hegel provides a fully teleological one. In the Hegelian view, world history is the progressive realization of freedom. Institutions may collapse, empires may fall, but these events are moments within a larger rational process. Decline is never merely loss; it is a stage in the dialectical unfolding of human self-consciousness.
Norberg’s argument is fundamentally incompatible with this vision. Peak Human offers no guarantee that freedom will reassert itself after periods of repression, nor that openness will spontaneously regenerate once suppressed. Golden ages end, and often decisively. Intellectual traditions disappear. Technologies are forgotten. Commercial networks dissolve. History, in Norberg’s telling, does not insure humanity against its own political failures.
This rejection of teleology is one of the book’s quiet but important virtues. Norberg does not deny that progress has occurred—indeed, he documents it extensively—but he insists that progress must be explained without recourse to historical inevitability. Institutions do not progress because they are expressions of reason; they persist only so long as coalitions in their favor remain politically dominant. History is contingent.
As noted above, Norberg’s closest intellectual relatives are thus found not in stadial or teleological theories, but in the rise-and-decline tradition inaugurated by Edward Gibbon and given formal economic expression by Mancur Olson.
Gibbon’s Decline and Fall remains a masterpiece of historical synthesis, but it is not a theory in the modern sense. Rome declines through a confluence of causes: administrative centralization, military overextension, loss of civic norms, religious transformation, and external pressure. What Gibbon offers is a narrative sensibility—a recognition that civilizations decay not suddenly, but through cumulative institutional weakening.
Olson, by contrast, provides a sharply specified mechanism. In The Rise and Decline of Nations (Yale University Press, 1982), Olson argues that stable societies inevitably accumulate organized interest groups that seek redistribution rather than production. These “distributional coalitions” slow economic growth by raising transaction costs, blocking innovation, and diverting resources toward rent seeking. The longer a society remains stable, the more such coalitions proliferate, and the more rigid its institutions become.
Norberg accepts Olson’s diagnosis as far as it goes, but he treats it as necessary rather than sufficient. Interest-group sclerosis explains why mature economies slow down, but it does not fully explain why societies abandon the deeper cultural commitments—toleration, openness to foreigners, intellectual freedom—that underwrite innovation in the first place. Norberg’s historical cases suggest that something more than coalition politics is at work.
In Peak Human, decline is not merely the result of too many lobbyists. It is also the product of status anxiety, ideological consolidation, and fear of disruption. Golden ages empower outsiders—merchants, immigrants, heretics, innovators—whose success threatens established hierarchies. As wealth accumulates, the incentive to control entry, restrict competition, and enforce orthodoxy grows stronger. Elites discover that closure is safer than openness once they have something worth protecting.
Seen this way, Olson’s institutional sclerosis becomes part of a broader political economy of closure. Distributional coalitions do not merely seek economic rents; they also reshape culture and ideology to legitimize exclusion. The result is not only slower growth, but a narrowing of the intellectual and social space in which innovation occurs.
Norberg’s most original contribution lies in his reframing of golden ages themselves. Rather than treating them as peaks on a long upward slope, he treats them as unstable equilibria—temporary alignments of incentives that permit unusually high levels of experimentation and exchange. These equilibria are productive precisely because they relax constraints: on trade, on belief, on identity, on enterprise. But they are unstable because relaxation threatens control.
This framework allows Norberg to explain both the recurrence of golden ages and their brevity. Progress reappears whenever societies rediscover openness, but it rarely lasts because openness is costly to defend politically. Fear, envy, and rent seeking are not aberrations; they are predictable responses to success.
In this sense, Peak Human offers a synthesis that neither Gibbon nor Olson quite achieved. It combines Gibbon’s sensitivity to historical contingency with Olson’s attention to incentive-driven institutional decay, while adding a cultural and ideological dimension that explains why societies so often choose restriction over discovery.
Peak Human is best read not as a book about decline, but as a book about the conditions under which progress can survive. Norberg does not deny the extraordinary achievements of modern liberal societies; indeed, he celebrates them. But he refuses to treat those achievements as self-sustaining. Markets, tolerance, and innovation do not defend themselves. Golden ages end not because a society’s people have exhausted their individual creative potential, but because as a group they lose the institutional and moral courage to tolerate the disorder that creativity entails. Our will to improve may be made of iron, but iron rusts.
