The Passions and the Interests: Political Arguments for Capitalism Before Its Triumph

One of the more peculiar features of intellectual history is the half-life of the arguments that win. Once a position has prevailed — once its conclusions have been absorbed into common sense and its alternatives have been marginalised or forgotten — the arguments that secured its victory tend to drop out of sight, replaced by retroactive justifications that make the outcome seem natural, inevitable, or self-evidently correct. Albert Hirschman’s The Passions and the Interests, published in 1977, rescues from precisely this fate the arguments that recommended capitalism to early modern political thinkers — and in doing so reveals that those arguments were not the ones that subsequent generations of both defenders and critics have supposed. It is a work of intellectual history that functions as a work of social theory: by recovering what capitalism’s original advocates actually claimed on its behalf, Hirschman makes visible the gap between those claims and the capitalism that arrived, and opens a set of questions about the relationship between commercial society, political stability, and human character that contemporary debate has largely forgotten to ask.

The Core Claim

Hirschman’s argument is organised around a conceptual transformation in European political thought between roughly the sixteenth and eighteenth centuries. Medieval and Renaissance political theory inherited from classical antiquity a concern with the passions — the volatile, potentially destructive forces of ambition, pride, glory-seeking, and avarice — and the standard responses to this concern were either repression (through moral education, religion, or law) or the channelling of destructive passions into less harmful outlets. What Hirschman traces is the emergence, across a range of thinkers — Bacon, Spinoza, Mandeville, Montesquieu, Steuart, and eventually the Scottish Enlightenment — of a different strategy: the notion that one passion might be used to contain and domesticate others. Specifically, the interest in material acquisition — what would become the commercial interest — came to be seen as a calm, predictable, and calculable force that could act as a counterweight to the passionate pursuits of honour and glory that had made princes and peoples ungovernable.

The word “interest” is Hirschman’s analytical pivot. Its semantic history — from a term covering all of a person’s legitimate concerns, including honour, to a term narrowed specifically to material self-interest — tracks the conceptual shift he is describing. As the commercial interest came to monopolise the concept, it acquired a specific set of attributed characteristics: constancy, predictability, and a tendency toward mutual accommodation rather than zero-sum conflict. Where passions clashed, interests could be balanced. This made the rise of commercial society legible as a solution to the problem of political instability that had obsessed European thinkers since Machiavelli — not primarily as an engine of prosperity but as a pacifying force, a mechanism for transforming the dangerous volatility of passionate human beings into the manageable calculability of economic agents.

The second movement of the argument, briefer but equally important, examines what was claimed specifically for the political consequences of commerce. Montesquieu’s doux commerce thesis — the claim that commercial exchange softens manners, promotes peace, and generates the conditions for representative government — and Sir James Steuart’s account of the merchant-based economy as a structural constraint on princely arbitrariness: these were arguments about the political sociology of capitalism, not merely its economic efficiency. The merchant’s need for stable property rights, predictable law, and reliable currency gave him an interest in limiting arbitrary power that aligned, at least contingently, with the interests of subjects more broadly. Commerce, on this account, was a school of civic virtue by another name.

Where the Argument Is Strongest

The historical recovery itself is the book’s primary and irreplaceable achievement. Hirschman reads across an enormous range of early modern texts — political theory, economic pamphlets, moral philosophy — with a lightness of touch that makes the intellectual transformation he is tracing feel both intellectually surprising and historically inevitable once it has been shown. The semantic history of “interest” alone is worth the book: to watch a concept expand to cover all legitimate concerns, then contract to mean almost exclusively financial self-interest, while retaining the evaluative valence of the broader term, is to watch a significant piece of ideological work being performed, and Hirschman makes it visible without reducing it to mere ideology.

The identification of the pacification argument as capitalism’s original political recommendation is the move with the widest consequences. Modern debate about capitalism tends to be organised around its economic properties — its efficiency, its dynamism, its tendency toward inequality — and its defenders and critics alike largely accept this framing. Hirschman shows that its earliest and most philosophically sophisticated advocates recommended it on entirely different grounds: not that it would maximise welfare, but that it would replace the dangerous unpredictability of passionate politics with the stable calculability of commercial exchange. This argument was falsified, on Hirschman’s own retrospective assessment, by the history that followed — capitalism generated its own distinctive passions and instabilities, and the doux commerce thesis did not survive contact with industrial society — but its very failure is illuminating. The capitalism that arrived was not the capitalism that was promised.

The book’s density — it is barely 130 pages of argument, with a precision of construction unusual even in Hirschman’s work — is itself an intellectual achievement. Each of the thinkers he reads is given only enough space to yield the argument, and the cumulative effect is to demonstrate a transformation in European political thought through a series of close readings that collectively add up to an interpretive thesis considerably more ambitious than any of them individually states. This is intellectual history at a level of compression that most practitioners of the genre do not attempt and fewer still achieve.

Where It Strains

The thesis’s parsimony — its greatest virtue — is also its main liability. Hirschman traces one thread of the pre-capitalist argument for commercial society with exceptional care, and in doing so necessarily leaves others underexplored. The efficiency and prosperity arguments for capitalism — that commercial exchange generates wealth and that wealth improves life — were present throughout the period he covers, not merely as supplements to the pacification argument but as independent and influential lines of thought. Smith’s Wealth of Nations, which appears in Hirschman’s account primarily as the moment when the interest-passion conceptual distinction lost its organising power, also contained a sophisticated productivity argument that mattered to its contemporary reception in ways that treating it primarily as an episode in the history of interest theory does not fully capture. The selection is legitimate but the frame risks making the intellectual history look tidier than it was.

The retrospective falsification of the doux commerce thesis — Hirschman’s acknowledgement, in the book’s final pages, that commercial society generated its own distinctive disorders rather than pacifying political life — is gestured toward rather than argued. He cites, briefly, John Stuart Mill’s disillusionment with the political character of commercial society and a few later critics, but the account of why the original argument failed — what it missed or misrepresented about the dynamics of commercial society — is not developed with the same rigour as the account of the argument itself. This creates a structural asymmetry: the case for capitalism as pacifier is presented in full historical and conceptual detail, while its falsification is treated as self-evident to the modern reader. The implicit verdict on capitalism’s political legacy is accordingly less examined than the case for capitalism that precedes it.

The social and economic actors in Hirschman’s account are, with notable exceptions, the princes, political theorists, and merchant elites of early modern Europe. The labour that commercial society organised, the populations whose lives were transformed by the spread of market exchange, the subaltern interests that did not map onto either passionate aristocrats or calculating merchants — these are largely absent. This is appropriate to an intellectual history focused on the arguments of a particular class of thinkers, but it means that the transformation Hirschman describes is visible only from above, and the passions and interests of those who experienced commercial society as its subjects rather than its architects are not part of the story. Read against Thompson or Polanyi, the gap is conspicuous.

Verdict

The Passions and the Interests is one of the small number of works in the history of economic thought that genuinely changes how one reads the texts it discusses — and, by extension, how one reads the tradition of argument about capitalism that those texts inaugurated. Its specific thesis, the pacification argument for commercial society, is less widely known than it deserves to be, and Hirschman’s recovery of it has consequences for how we evaluate both the promise capitalism made to political modernity and the nature of its failure to keep it. The book’s limitations are those of its scope rather than its execution: it does not purport to be a full account of early modern economic thought, and the retrospective assessment of the thesis it recovers is compressed to the point of incompleteness. Read it alongside Polanyi’s The Great Transformation for an account of what commercial society actually produced in the way of political disorder and social dislocation — the counter-evidence to doux commerce rendered in historical detail — alongside Hirschman’s own Exit, Voice, and Loyalty for the social theory that his intellectual history consistently implies but only occasionally states, and alongside Emma Rothschild’s Economic Sentiments for the most rigorous subsequent treatment of Smith and Condorcet on the politics of commercial society. It is the kind of book that makes the questions it raises feel both urgent and, before it was written, somehow unaskable — which is the rarest and most valuable thing intellectual history can do.
