Emil Lederer, Zur neueren geldtheoretischen Literatur I (1920/21)

Emil Lederer’s review of Kurt Singer’s Das Geld als Zeichen examines the relationship between monetary theory and cultural interpretation. Its connected criticisms concern Singer’s adoption of Knapp’s state theory of money and his treatment of monetary institutions as expressions of historical epochs. While acknowledging Singer’s analytical strengths, Lederer insists that legal definitions and cultural analogies cannot substitute for explanations of economic relationships.

Lederer examines Singer’s monetary theory independently of its philosophical framework because the book itself claims to offer such a theory. His first objection concerns its presentation of competing positions:

Singer sieht nur die »Metallisten« und vergißt, daß selbst Ricardo schon das Problem der Möglichkeit und der Bedingungen einer stoffwertlosen Währung für die Wirtschaftsverhältnisse seiner Zeit richtig gestellt hat.

English translation: Singer sees only the "metallists" and forgets that even Ricardo had already posed correctly, for the economic conditions of his own time, the problem of the possibility and the conditions of a currency without commodity value.

The opposition between metallism and monetary nominalism obscures an existing tradition of analysis. Lederer also objects to reducing quantity theory to its crudest form and neglecting contributions by Schumpeter, Fisher, and Mises. Singer’s polemic exaggerates the unity of its opponents:

Es wird immer mit einer »herrschenden Meinung« operiert, die ja gerade auf dem Gebiete des Geldwesens nicht besteht; es müßte denn sein, daß man den Wortlaut der Währungsgesetze als Ausdruck der »herrschenden Meinung« auffaßt.

English translation: One always operates with a "prevailing opinion" which, precisely in the field of monetary affairs, does not exist; unless one were to take the wording of the currency laws as the expression of the "prevailing opinion."

The criticism moves from intellectual history to the central theoretical difficulty: whether a legally defined monetary unit can be understood apart from its purchasing power.

Um nur das Wichtigste zu formulieren: durchaus problematisch ist der Begriff der »Werteinheit«.

English translation: To formulate only the most important point: the concept of the "unit of value" is thoroughly problematic.

For Lederer, money’s capacity to discharge state-recognized debts is only one aspect of what it can pay for. The practical persistence of a nominal unit depends on participants treating money as relatively stable in purchasing power and on fluctuations remaining tolerable. State authorization alone cannot explain monetary acceptance. This argument does not decide whether purchasing power derives from metallic value or from money’s character as a claim on goods; it identifies the exchange relationships that theory must explain.

Monetary policy exposes related limits. Replacing metallic backing with exchange-rate stabilization and discount policy still requires an account of the balance of payments, credit creation, and cyclical fluctuations. Lederer praises Singer’s discussion of money creation and the business cycle, while finding much of its substance in Bendixen. Making the Reichsbank responsible for currency stability and cyclical supervision would effectively charge it with organizing the national economy, without adequately explaining that task. Gold backing is neither universally sustainable nor theoretically indispensable, but under normal conditions supplies a costly, comparatively reliable mechanism. Commercial banks’ creation of spendable deposits further complicates central-bank control. Monetary management must therefore be situated within broader economic policy.

The historical criticism addresses Singer’s association of monetary forms with Greek antiquity, the Middle Ages, and English capitalism. Lederer favors distinctions grounded in economic structure, invoking Simmel against an interpretation organized around cultural essence. Singer’s movement between monetary institutions and ideas about money allows evidence concerning one to support claims about the other.

Aristotle provides a decisive example. Lederer distinguishes the Politics’ explanation of money as facilitating exchange from the Nicomachean Ethics’ treatment of just exchange relations. In the latter, needs establish comparability, while money represents and mediates that relationship. Neither account warrants projecting Knapp’s modern notion of legal validity into Aristotle or identifying a uniquely Greek monetary essence. The sociological question is which monetary arrangements particular social conditions made possible.

Likewise, medieval monetary fragmentation can be explained through relatively separate exchange territories, and debasement through rulers’ fiscal interests and changes in metallic content. Such mechanisms explain more than describing money as a symbol of political plurality. Currency collapse does not itself establish capitalism’s supersession: the French Revolution shows that monetary destruction can accompany bourgeois-capitalist advance. Singer’s contrast between German crisis and English resilience also neglects concrete differences in public finances, productive resources, wartime losses, and foreign assets.

Invoking Max Weber’s ideal of scholarly dedication, Lederer concludes by defending disciplined inquiry against suggestive speculation. He accepts that monetary institutions and theories are historically conditioned. His demand is to specify what is conditioned and through which relationships, connecting legal forms, purchasing power, credit, and economic structure rather than replacing explanation with analogy.
