When interests clash: the world before production

The notion of harmony of interests is a fundamental pillar of liberal thought, yet it is frequently dismissed with skepticism. Opponents of liberalism regard it as utopian, a naïve dream, on the premise that human interests are fundamentally antagonistic. But does this objection hold up? Not if we examine carefully the conditions under which interests truly clash, and those under which they naturally converge.

Frédéric Bastiat devoted the last and greatest work of his tragically short life to precisely this question. He died of tuberculosis in 1850, at the age of forty-nine, leaving the Harmonies économiques unfinished. But what he completed suffices to establish his thesis: the apparent conflicts of interest that fill the history books are not the natural condition of free men; they are the product of systems of privilege, monopoly, and political appropriation. He wrote, in the famous opening pages:

"If the natural tendencies of mankind are so bad that it is not safe to permit people to be free, how is it that the tendencies of these organisers are always good? Do not the legislators and their appointed agents also belong to the human race? Or do they believe that they themselves are made of a finer clay than the rest of mankind?"

In other words, the pessimism about human nature that justifies intervention is self-refuting: if men are too wicked to be trusted with freedom, they are equally too wicked to be trusted with power. The harmony of interests is not a claim that men are angels; it is a claim that free exchange aligns their self-interest with social benefit more reliably than any alternative.

Bastiat Economic Thought

To gain a deep understanding of the life, influences, opponents, and economic theories of Frédéric Bastiat, a 19th-century French economist and thinker.

To understand this harmony, we must first ask: under what circumstances are human interests truly opposed? In the earliest ages of humanity, human beings found themselves in direct competition for limited resources that nobody had produced. Nature offered fruit trees, fish in rivers, resources on the seashore, but no human society had created these riches. Appropriation was by force and destruction rather than by production, and there was only one way to grow rich: take what your neighbour possessed, or fight for access to resources that nobody had cultivated. In such a world, every gain was necessarily someone else's loss.

The birth of harmonious exchange

The modern world rests on a radically different principle: the production of new utilities. From the moment agriculture appears, when the wheat field becomes a genuine source of wealth, truly voluntary exchanges are born that enrich both parties simultaneously.

Bastiat expressed this transformation with his characteristic gift for vivid illustration:

"Consider the two men before us. One has wheat; the other has cloth. Neither has what the other needs in its most useful form. They exchange. After the exchange, each has more of what he needs than before. Nothing has been created from nothing; and yet both are richer. This is the miracle of exchange, the miracle that has built civilisation, the miracle that the enemies of commerce have always failed to understand."

As the Abbé de Saint-Pierre observed in the French liberal tradition, relationships founded on contract, respect for the rights of others, and voluntary exchange form a "chain of harmony" linking individuals, communities, and nations.

This harmony has been constructed gradually. The opening of the world through navigation, the development of transport technologies enabling more regular and extensive trade, and the security guaranteeing commercial relations have together built an ever-widening web of interdependence between suppliers, customers, and all economic agents. This interdependence becomes most visible in times of crisis. The American Civil War of the 1860s provides a striking illustration: by severing the cotton trade, the conflict brought ruin to textile industries across Europe, particularly in Lyon, despite the fact that France was not a belligerent. In other words, the impoverishment of one link in the chain immediately impoverished all the others.

International peace as the condition for prosperity

The need for international peace flows logically from this global harmony. Since trade is a positive-sum game in which all parties mutually enrich each other, it becomes imperative to maintain security both within societies and between nations. Every disruption to the world economic order produces nuisances that reverberate throughout the entire chain of exchange.

Gustave de Molinari, who directed the Journal des économistes for decades and outlived nearly all his contemporaries, devoted his late career to what he called a veritable "war on war." In his Grandeur et décadence de la guerre (1898), he argued with characteristic rigour:

"War was once rational, in the narrow sense that the gains from successful plunder could exceed the costs of the campaign. This is no longer the case. The world economy is now so tightly woven that the destruction wrought by war falls not only on the defeated party but on the victorious one as well, not only on the belligerents but on all their trading partners. The industrialist who cheers for victory is cheering for the destruction of his own markets. He does not see this because he sees only what is immediate; he does not see the invisible, long-term harm that commerce concealed."

Indeed, in the fifteenth or sixteenth century, a conflict in Africa or Asia would scarcely have affected European populations, because the sphere of exchange remained narrow and societies lived in relative self-sufficiency. Today, that insulation has vanished. The more extensive the chain of exchange, the more devastating any break in it becomes, which paradoxically constitutes a powerful argument in favour of peace.

Molinari was explicit about the implication:

"Free trade is not merely an economic policy; it is a peace policy. The nations that exchange goods do not send armies against each other, because the cost of rupture is too high for both parties. The protectionist who imagines he is defending his nation is in fact preparing its wars."

The liberal programme for peace

The transition to a peaceful world is, however, a long apprenticeship. Human societies remain marked by ancient conceptions of production through violence, conquest, hunting, and gathering. The new conceptions of peaceful production, exchange, and harmony must be learned and disseminated, and this is a work of generations.

The Abbé de Saint-Pierre (1658-1743), one of the earliest thinkers on perpetual peace, proposed international institutions capable of guaranteeing the rule of law on a global scale. Frédéric Passy (1822-1912), the economist and peace campaigner who became the first Nobel Peace Prize laureate in 1901, a remarkable distinction for a man who had spent fifty years arguing in economic rather than sentimental terms for the incompatibility of free trade and war, placed his confidence in public opinion: if peoples understood that their prosperity depended on the prosperity of their trading partners, the demand for peace would become irresistible.

Bastiat, for his part, saw free trade itself as the surest foundation for peace. In his celebrated debate with the protectionist Adolphe Thiers before the French Chamber of Deputies, he cut to the essence:

"When goods do not cross borders, armies will. This is not a metaphor; it is history. The periods of greatest commercial openness are the periods of greatest peace. The periods of greatest commercial restriction are the periods of greatest war. Causality runs in both directions: free trade makes war less likely, and war makes free trade impossible. They are, in the deepest sense, opposites."

Liberalism thus presents itself as a great harmonious chain of exchanges and contracts, founded on freedom and property, enabling progress and improving the situation of every individual. The "chain of harmony" that the Abbé de Saint-Pierre described in theory has become, through the development of world commerce, a palpable, material reality.
