It would not seem to be stretching matters unduly to assert that widespread agreement could be found on the following related propositions: (1) that the social crises and upheavals in Europe between the two World Wars, and the wars themselves, were not aberrations but are, rather, susceptible of a systematic, coherent explanation; (2) that such an explanation, though it would rest on a myriad of social relationships and processes, would place economic affairs at or near the center of Europe's troubles; and (3) that an understanding of European economic difficulties in the period might be efficiently achieved through an analysis of the factors stimulating and retarding the rate of economic growth of interwar Europe—or, that any thorough explanation would have to include such an analysis.
