His Work Lives

Summary

This file is a brief commemorative reminiscence by Fritz Machlup. Its scope is personal, institutional, and intellectual: Machlup presents Ludwig von Mises as teacher, seminar leader, political seer, theorist of method and socialism, and exemplar of liberal commitment. The central thesis is that Mises’s work survived not only in books but in students, debates, and institutions.

IT WAS in 1921 that I met my master.

The opening scene establishes discipleship through rigor. Mises admits Machlup only after testing whether he can enter the international language of economics.

‘Economics is written in English.’

Machlup then distinguishes the university seminar from the private Privatseminar at the Chamber of Commerce. The latter becomes the essay’s key institution: selective, interdisciplinary, and formative for a generation of economists and philosophers. Mises’s influence is therefore represented as a living intellectual network rather than a mere bibliography.

Thus Mises’ work lives in many forms, and one of them is through the writing and teaching of those whom he inspired.

The memoir next turns from pedagogy to prophecy. Machlup insists that Mises was not a forecaster in the statistical sense; his “prophecy” was judgment about institutions and civilization. The Kreditanstalt anecdote illustrates both Mises’s foresight and human inertia before foreseeable disaster.

It shows that on the best of prophecies people do not act.

A darker prophecy concerns the collapse of freedom in Central Europe. Mises’s joking fantasies of exile later become practical counsel, and Machlup frames the departures of Hayek, Haberler, Mises, and himself as obedience to “the master’s advice.” The essay’s structure then deliberately pivots from memory and fate to scholarship.

From Mises the prophet I return to Mises the scholar.

Machlup’s core conceptual defense concerns Mises’s apriorism. Against critics who caricature it as empty certainty, he stresses that a priori theory does not mechanically predict historical events; its application depends on judgment about circumstances.

Perhaps I should add that his apriorism did not mean that you could predict with certainty any events or developments in human affairs.

This distinction lets Machlup present Mises as both rigorous and empirically alert: theory supplies the model, but practical use requires discernment. The point matters for the philosophy of social science, where Mises remains part of live debates over apriorism, falsificationism, and methodology.

Machlup’s second major example is the socialist calculation argument. At an International Economic Association congress in Budapest, he finds Mises’s critique acknowledged even by socialist economists in private. Their difficulty is precisely the one Mises had identified: without genuine markets, prices become administrative fictions rather than guides to allocation.

‘We do not know how to use prices,’ my socialist partners would admit; and some of them went on to say that many of the prices of staple commodities were based on the prices recorded in the free world markets, translated by fictitious exchange rates into their own prices and fixed for five years.

The relevance of the piece lies in this movement from personal recollection to historical validation. Machlup does not offer a systematic exposition of Mises’s economics; instead, he argues that Mises’s ideas remained active in philosophy of science, socialist economies, and liberal institutions. Yet he ends with a warning: Mises’s scholarly influence may live widely, but his commitment to liberty is fragile outside circles such as the Mont Pelerin Society.

Mises’ commitment to liberty must be preserved; and as we affirm our love and respect for our deceased teacher we take the opportunity to reaffirm our own commitment to individual freedom.
