Economists dismiss pre-eighteenth-century thought as pre-scientific; historians lack the tools to spot economic theory buried in older texts. Against that double neglect, Schumpeter praises Father Dempsey's study of interest and usury for reading late-scholastic theology from within while judging it by modern standards. The Jesuits Molina, Lessius, and de Lugo, he argues, worked in a world already full of money markets, speculation, and negotiable paper, and their empirical method did not differ in logical character from ours. The essay's conceptual center is a sharp separation: economic analysis is valid or invalid autonomously, whatever moral use its results are later put to. From this Schumpeter defends both the scientific seriousness of scholastic inquiry and his warning that modern clergy pronouncing on money and banking must first master the technical economics involved.

Interest holds so central a position in the capitalist organism that it intrudes in practically every economic consideration or valuation.

Written weeks after Keynes's death, this memoir refuses to separate the theory from the man who made it: a Cambridge and Eton mind, mathematically gifted yet impatient with technique that did not bear on public action. Schumpeter reads the whole career as the slow forging of a single vision, first glimpsed in The Economic Consequences of the Peace, that laissez-faire capitalism had ended in 1914 and that thrift no longer served accumulation. The General Theory supplies that vision its machinery, reducing the economy to three schedules: the consumption function, the marginal efficiency of capital, and liquidity preference. Admiring the elegance yet insisting on the narrowness, Schumpeter accepts Hicks's verdict that this is the economics of depression, and grants Keynes a genuine school rivaling the Physiocrats and Marxists.

It does not make us Keynesians, it makes us better economists.

Provisional notes rather than a finished theory, this essay asks how economists and historians should define, measure, and explain long-run change without turning theory into metaphysics. For Schumpeter theory is only an empirical toolbox: growth itself has no all-purpose measure, and he adopts the rise of trend per capita output merely as a working definition. His three theses cut against reductionism, that growth cannot be isolated from politics, institutions, and habit, that no single factor explains it, and that it interacts reciprocally with its supposed causes, while he rejects Marxist determinism outright. Naming a factor like war or the sixteenth-century Spanish precious-metal inflation is worthless, he argues, until its mechanism is specified. Against the automatism of the Smith-Mill-Marshall tradition he sets the creative response and entrepreneurship, the recombination of resources that no prior condition can predict.

Economic growth is not an autonomous phenomenon, that is to say, it is not a phenomenon that can be satisfactorily analyzed in purely economic terms alone.

The mechanics of inflation are not obscure; what defeats every cure is the refusal of the groups who count politically to pay the price of stopping it. Reading the American inflation of 1948 through the post-1918 collapses of Austria, Germany, Italy, and France, Schumpeter defines inflation as means of payment rising faster than output and divides the disease into three stages: incipient, advanced, and wild. America, he judges, has reached the advanced phase, where full employment turns new money into general price increases and bank lending breeds secondary credit inflation, the national payroll serving as its chief conductor. His program rejects price rollbacks and direct controls in favor of credit restriction, budget surpluses, and taxes that reward saving, warning with a nod to Lenin that a debauched currency corrodes the very classes on which the social order rests.

So inflation runs on by common consent.

These are not the famous treatise but dense student notes from a 1949 Institute of World Affairs lecture, circulated by Arthur Smithies as the fullest exposition he knew of Schumpeter's late thought. Against Trotsky's claim that imperialism is capitalism's last stage, Schumpeter advances laborism: a society, exemplified by Britain, where labor's interests become the state's governing purpose. Higher wages, shorter hours, subsidies, and cheap money redirect the fiscal state away from capital renewal and defense toward present labor consumption. His feudal analogy is deliberately provocative, since modern redistribution does not abolish the class use of the state but inverts it. A laborist Britain, he predicts, cannot sustain great-power burdens and grows dependent on America, while a dictatorial Russia mobilizes for power politics Britain cannot match.

The working class has replaced Mme. du Barry, and we have the inverse of the feudal system.

Schumpeter traces the entrepreneur through the history of economic thought, from Cantillon and Say who grasped him to Smith, Ricardo, and Marx who dissolved him into the capitalist, in order to isolate a function that ownership, management, and risk-bearing all fail to capture. The entrepreneur is whoever institutes new combinations, breaking routine rather than administering it, and his gain is neither wage nor monopoly rent but a surplus that congeals into industrial fortunes. That function may be corporate or collective as easily as individual, and banks figure not as passive intermediaries but as organs that call new industries into being. The essay's second half turns concept into a research program, pairing theory with the history of firms, finance, and technology, and refusing to equate the cultural imprint of entrepreneurial mentality with direct political rule.

I shall state frankly that I consider power to be one of the most misused words in the social sciences, though the competition is indeed great.

Six recent English books, by Baster, Franks, Harrod, Jewkes, Meade, and Robbins, give Schumpeter his occasion to ask whether economists have drawn a serious analytic harvest from Britain's postwar experiment in state management. His first move is to prise apart three questions habitually merged under planning: socialism, meaning central control of production; laborism, meaning labor's political ascendancy within a still-private economy; and the sheer readjustment of exports, saving, and solvency after the war. Nationalizing coal or transport, he insists, proves neither socialism nor its absence; the telling fact is that the wage rate has become a political datum, protected as a matter of course while profits and rents are compressed. Britain's dollar shortage he reads as the outward face of domestic maladjustment, conceding that under laborite constraints direct controls may be forced expedients rather than doctrinal choices.

Nevertheless, there is point in keeping these three topics distinct, if only in order to show how they interact to produce the English problem.

How does bias enter a science whose tools, time series, value theory, marginal productivity analysis, are in principle neutral? Schumpeter locates it not in open advocacy, which may be perfectly honest, but in the pre-scientific act of vision: the moment before proof when the investigator perceives which phenomena connect and matter. Models and statistics can be tested and refuted; vision cannot, and so it becomes the true gateway of ideological bias. He tries the thesis on three economists: Smith, whose natural-law slogans did little harm because his analysis stayed sober; Marx, who discovered ideology yet let his creed of class struggle and increasing misery sterilize his analysis; and Keynes, whose stagnationist vision gained technical armor and then dissolved into professional controversy. Ideology, he concludes, both retards science and supplies the vision without which it might never advance.

And so—though we proceed slowly because of our ideologies, we might not proceed at all without them.

What survives of the Communist Manifesto once it is read strictly as science, stripped of centenary celebration and debunking alike? Schumpeter answers by treating the 1848 pamphlet as economic sociology, separating that interpretive achievement from its thin technical economics. He ranks Marx's economic interpretation of history beside Darwin's in originality, credits him with hauling the theory of the state down from metaphysics into realistic analysis, and salutes the Manifesto's unrivalled panegyric to bourgeois enterprise as a 'constant revolutionizing of production.' Yet he dismantles the predicted polarization into two classes, the overlooked new middle class, and the doctrine of the withering state. What remains is an ideological document read as analysis, the prelude, Schumpeter says, to the whole of Marx's later work.

it is but steam that rises from the galloping horse.

Twenty-odd centuries of economic reasoning, from Aristotle and the scholastic doctors through Smith, Ricardo, Walras, and Keynes, pass under review in this vast and unfinished history, assembled from Schumpeter's disordered manuscript by his widow Elizabeth Boody Schumpeter. Its governing distinction separates economic analysis, the evolving box of scientific tools, from the surrounding economic thought and political creed. Tracing the filiation of ideas, Schumpeter insists that competent analysis rests on three techniques, history, statistics, and theory, and that every theorist first works from a pre-analytic 'vision' colored by ideology. He crowns Walrasian general equilibrium the summit of theoretical economics, weighs the scholastics' neglected contributions against the British classical tradition he distrusts, and reconceives capital, from the standpoint of analysis, as a set of restrictions.

practically and analytically, a credit theory of money is possibly preferable to a monetary theory of credit.

Left with Arthur Spiethoff before Schumpeter sailed for Harvard, then set aside for decades, this posthumous and partly fragmentary manuscript, edited by Fritz Karl Mann, pursues a single question: what money essentially is. The answer inverts orthodoxy. Money is no commodity but a technical instrument of social accounting, and payment is at bottom a matter of crediting and debiting, of clearing claims through a social ledger. From general-equilibrium reasoning Schumpeter extracts a 'critical number' that fixes absolute prices and imposes the Geldligament, the specifically monetary constraint on the economy. He demolishes the 'deposit legend' that banks merely lend out entrusted funds, holds that every bank credit creates a deposit, contests Mises and Weber on socialist calculation, and turns Knapp's state theory of money into a cautionary tale of fruitless doctrine.

A polite acknowledgment that swells into a memorandum on statecraft, this wartime letter to Count Otto Harrach, unpublished until 1992, turns Schumpeter's praise of Harrach's composed detachment into a warning. Neutral initiatives, he argues, are not peripheral gestures but instruments capable of shaping the terms of peace, and no belligerent is so well advised as Austria to cooperate with them. He laments how alien the United States, financially and politically decisive, remains to Austrian diplomatic and finance-ministerial circles, drawing on his own earlier stay in America. The letter darkens toward its close: intensified submarine warfare, he fears, will alienate Washington and stiffen English resolve, and the deeper the gulf between the blocs grows, the more the Monarchy falls subordinate to Berlin, forfeiting the Western sympathies that might have served it at the peace.

Die Zeichen der Zeit sind düster.
