Mises’s Nationalökonomie reconstructs economics as a general theory of human action. Against historicism, positivism, and doctrines that make reason class- or nation-bound, it treats economic laws as implications of purposeful choice. Economics does not measure psychic quantities; it analyzes the form of preferring, choosing, and using scarce means for selected ends.
Im Handeln wird nicht gemessen und nicht gewogen, im Handeln wird nicht gleichgehalten, sondern gewählt, d.h. vorgezogen und zurückgestellt.
English translation: In action nothing is measured and nothing is weighed; in action things are not treated as equal, but chosen—that is, preferred and set aside.
This methodological claim grounds Mises’s subjectivism. Value is not an objective property of goods but is imputed by acting persons who rank alternatives. Costs, prices, capital, money, and profit become intelligible only within plans formed under scarcity and uncertainty. Economic science can judge whether means are suitable to ends, but it cannot prescribe ultimate ends themselves. Its discipline is therefore both theoretical and anti-technocratic: it refuses natural-scientific imitation as well as historical relativism.
From action Mises turns to society. Social cooperation is neither an organism above individuals nor a mechanical product of material forces. It emerges because persons grasp the advantages of exchange and the division of labor. Mises thus reverses materialist explanation by giving priority to ideas, expectations, and institutions.
Mithin ist Gesellschaft ein Produkt der Ideologie, und nicht die Ideologie ein Produkt der Gesellschaft.
English translation: Society is therefore a product of ideology, and not ideology a product of society.
The market order is the most developed form of this cooperation. In it, social coordination proceeds through exchange rather than command. Prices are not arbitrary conventions or moral verdicts; they condense the competing valuations of buyers and sellers and transmit information about alternative uses of resources. Entrepreneurs respond to these signals, bear uncertainty, and reallocate capital through profit and loss.
Der Markt lenkt, der Markt bringt in das Getriebe Sinn und Ordnung.
English translation: The market directs; the market brings meaning and order into the machinery.
The sentence expresses not a simple doctrine of automatic harmony but a theory of calculation. Money prices make heterogeneous goods, labor, and capital goods comparable in business accounts. They permit entrepreneurs to estimate whether projects conserve or waste scarce means. Mises therefore rejects the image of a social product first produced and then distributed among classes: wages, rents, interest, and profits arise within one pricing process for complementary factors.
The book’s central institutional thesis is that capitalism is defined by this possibility of monetary calculation. Money is important not merely as a medium of exchange but as the condition of capital accounting across time.
Das charakteristische Merkmal des Kapitalismus ist die Wirtschaftsrechnung.
English translation: The characteristic feature of capitalism is economic calculation.
This is also the basis of Mises’s critique of socialism. A socialist authority may command labor and resources, but without private ownership of the means of production there can be no genuine market for them. Without such markets there are no money prices for capital goods, and without those prices there is no rational comparison among technically possible plans. Planning can inherit or imitate earlier capitalist prices for a while, but it cannot reproduce the process that generates them.
The later sections extend this architecture to time, capital, money, credit, and intervention. Interest is rooted in time preference, not exploitation; capital goods embody past plans and must be maintained through calculation. Credit expansion can falsify interest-rate signals and produce unsustainable investment patterns. Price ceilings, subsidies, debt cancellation, exchange controls, devaluation, and inflation are treated as attempts to override market relations while continuing to depend on the order they deform.
Sie ist ein Hammerschlag, der zertrümmert und nichts kann als zertrümmern.
English translation: It is a hammer-blow that shatters and can do nothing but shatter.
Mises’s critique of interventionism is cumulative: partial controls fail to achieve their stated ends, invite further controls, and push policy either back toward the market or forward toward comprehensive planning. The unity of Nationalökonomie lies in linking epistemology, value theory, exchange, money, capital, socialism, and intervention around one argument: modern civilization depends on the fragile institutional device of market calculation through money prices. When that device is abolished or systematically distorted, production may continue physically, but rational economic orientation is lost.
