This file is a single-author conference paper, presented in 1945 and later printed in Economics and Ideas. Its genre is a programmatic liberal essay: Mises offers not a technical model but a compact philosophical defense of economics as a science of social cooperation. Its scope runs from older conflict doctrines, through utilitarian and classical economics, to socialism, protectionism, profits, consumer sovereignty, and the intellectual discipline required for economic judgment.
One of the fundamental theses of Classical Economics is the theory of the harmony of the rightly understood—we prefer today to speak of the long-run—interests of all individuals and groups of individuals within a society of private ownership of the means of production and free enterprise.
Mises begins by reconstructing the pre-economic view that society rests on coercion, moral self-denial, or religious discipline because human interests are naturally antagonistic. Against this, utilitarian philosophy and classical political economy show that scarcity need not produce permanent conflict once reason discovers specialization. Human beings escape the animal struggle over fixed supplies by increasing productivity through cooperation.
Labor performed under the system of the division of tasks is much more productive than the isolated efforts of self-sufficient individuals.
The essay’s central conceptual move is therefore to replace sacrificial morality with “rightly understood” self-interest. Peace, law, and exchange are not irrational renunciations of gain; they are the conditions of larger gains made possible by the division of labor. This also underlies Mises’s rejection of romantic primitivism and of “distribution” as an image of wealth parceled out from a common chest.
Mises next separates utilitarian liberalism from natural-rights rhetoric. The historical liberal movement may have used the language of innate rights, but the economic case for liberal institutions does not depend on it. Private property, free enterprise, and representative democracy are defended because they sustain the market order and reduce incentives for civil war and conquest. Against Marxism, he treats “polylogism” as an evasion of economic criticism: instead of refuting the case for market cooperation, it dismisses opponents as bearers of bourgeois logic.
The essence of the teachings of Utilitarian Liberalism is that the market system based on private property is the only workable pattern of social organization.
A key section recasts competition. Mises rejects the anti-liberal habit of treating market rivalry as Darwinian extermination or warfare. Competition is a peaceful sorting process in which consumers reward those who serve them better. Ricardo’s law of association becomes more than a doctrine of foreign trade: it is the general law showing that cooperation benefits participants even when their abilities are unequal.
Under capitalism, competition is the peaceful method to assign to every individual that place in society in which he renders the most valuable services to his fellow men.
The polemical center is the “Montaigne fallacy,” Mises’s name for the zero-sum belief that one party’s advantage must be another’s injury.
The profit of one man is the damage of another; no man profits but by the loss of others.
He traces this fallacy through protectionism, anti-import propaganda, and exploitation theories of labor. Its mistake is to isolate a transaction from the wider temporal system of production. The patient’s illness is not the source of the doctor’s gain; the gain comes from service rendered. Likewise, entrepreneurial profit arises from anticipating future wants and organizing resources accordingly.
The source of the businessman's profits is always his successful foresight in providing for future needs.
Mises’s defense of profit is institutional rather than celebratory. Profits and losses are signals that transfer productive resources toward entrepreneurs who satisfy consumers and away from those who do not. Inequality in an unhampered market has a dynamic function; when government protects incumbents, however, inequality becomes privilege. Liberalism, for Mises, is not a defense of today’s rich but of open competition against vested interests.
The market of a capitalist society is a consumers’ democracy.
The conclusion turns diagnostic. Mises argues that modern politics is obsessed with economic claims while neglecting economic study; this makes restriction, subsidy, tariff policy, and war appear rational. Economics is called “inhuman” because it identifies consequences, not because it commands hardship. Its relevance, especially in the aftermath of war, lies in showing that social life is not necessarily plunder.
The main achievement of economics is that it has provided a theory of peaceful human cooperation.
