Keynes’ Preface to the German Edition of the General Theory: Nazi Sympathies or Methodological Empathies?

In the (1936) preface to the German edition of The General Theory of Employment, Interest and Money, Keynes contrasts his methodology with that of Classical laissez-faire economics. He also compares and contrasts his methodology with German economics, which members of the German Historical School had heavily influenced. Unfortunately, some view Keynes as arguing in this Preface that his theory could more deductively apply to fascism than to laissez-faire economies. This would suggest an endorsement of Nazism. Of course, any support offered for Nazism should be condemned. However, instead of displaying Nazi sympathies, this paper argues that the Preface more likely supports the widespread methodological rejection in German economics of deducing laissez-faire outcomes from Classical postulates. Furthermore, Keynes criticizes the more inductive approach of many German economists, and states that he provides them with the theoretical framework which they could deductively apply to their totalitarian economy. Keynes should be read as arguing that his theoretical framework would prove more applicable to a totalitarian system than would a theory based on Classical laissez-faire economics. Comments in the Preface which seem to some to support Nazism should be taken, then, as support for the applicability of his theory to such a system. Keynes’ methodological arguments in the prefaces to the other editions, which reflect his overall methodological approach in the General Theory, his familiarity with German economics, his support for liberal economic and political institutions, and his anti-Nazism, all support this alternative interpretation. An earlier version of this paper was presented at the Midwest Economics Association Meetings in Chicago on March 16, 2008.
