Emil Sax · 1884
Sax presents Nationalökonomie as a discipline whose difficulty is not a single erroneous doctrine but a confused constitution. Older political economy has mixed theory with policy, private economy with social economy, and partial abstractions with universal laws. His aim is accordingly foundational: economics must determine its proper object, its legitimate methods, and the relation between theoretical explanation and practical direction.
ein Neubau von Grund aus in's Werk gesetzt werden müsse.
English translation: a rebuilding from the ground up had to be undertaken.
The need for such rebuilding arises from the distance between inherited doctrine and modern economic life. Sax treats the historical school, socialist criticism, and Menger’s methodological intervention as signs of the same crisis: classical economics can no longer be defended as dogma, yet economics must not dissolve into historical description, statistics, or political agitation. The task is to preserve theory by purifying it.
Die Kluft, welche sich da zwischen Wissenschaft und Leben aufthat, ward der unmittelbar mächtigste Anstoss der Reformbewegung.
English translation: The gulf that opened up between science and life became the most immediately powerful impetus of the reform movement.
Sax’s central conceptual distinction separates technical from economic action. Technical activity selects means for a given material end; economic activity orders ends and means under scarcity, social dependence, and the pursuit of external conditions of existence. Economics therefore is not coextensive with all practical action, nor reducible to exchange among private owners. It studies the ways human purposes shape technical conduct and social relations when external means are limited.
Volkswirthschaft ist die aus dem Streben nach Sicherung der äusseren Existenzbedingungen sich ergebende Bestimmung des (technischen) Handelns und der sozialen Beziehungen der Menschen.
English translation: The national economy is the determination of man's (technical) actions and social relations that arises from his striving to secure the external conditions of his existence.
This definition allows Sax to include individual, cooperative, and collective forms without reducing economics to general sociology. Robinsonades may clarify elementary relations, but they are only heuristic devices; real economic life is already social, institutionally mediated, and historically formed.
eine Einzelwirthschaft im stricten Sinne des Wortes ist eine Abstraction.
English translation: an individual economy in the strict sense of the word is an abstraction.
A second organizing distinction separates theoretical from practical Nationalökonomie. Theoretical economics investigates economic being, causal connection, and lawlike relations; practical economics formulates maxims for private conduct, administration, finance, and policy. Sax regards their confusion as one of the great errors of liberal doctrine: propositions abstracted from private exchange were turned into unconditional political rules. Concepts such as need, good, labor, production, consumption, value, and exchange become economic only when considered within the ordering of scarce means toward human purposes.
Methodologically, Sax accepts Menger’s defense of exact theory against a one-sided historicism, but he resists turning exactness into empty hypothesis. Abstraction is valid when it isolates causal elements from experience; it becomes false when it forgets the empirical and social conditions from which it was drawn. Historical and statistical inquiry remain indispensable, especially where motives, institutions, and collective formations cannot be reduced to simple calculable relations. His method is therefore plural rather than eclectic: exact, empirical, historical, and practical inquiries have different tasks within one science.
The book’s most distinctive social-theoretical element is its treatment of Individualismus and Collectivismus. Individualism is not mere egoism, since Sax distinguishes egoistic, mutualistic, and altruistic motives. Competition, reciprocity, family provision, charity, and cultural or humanitarian devotion all belong to economic analysis when they affect the securing of external conditions. Against both Manchester liberalism and socialism, Sax insists that actual economic life consists of mixed motives and varied institutional forms.
Collectivism, however, is not simply the aggregate of individual acts. It appears in durable formations—state, municipality, corporation, compulsory association—where economic purposes are organized through a higher unity. Sax rejects a mystical collective personality, but also rejects reducing the state to private contract. Public finance, administration, and collective provision are not external applications of economics; they belong to its theoretical object because collective life has economic necessities private action cannot satisfy.
