“The approach to the study of economic history that dominates the presentation of the subject in this volume is that of the economist whose immediate and primary function is to study the production and distribution of wealth with the objective of learning how the nation's economic progress can be promoted and its standard of living advanced. It can be called the functional approach to economic history. Although the narrative should provide such knowledge of the general background of economic history as is needed for most purposes in the interpretation of political history, and has frequently been turned aside to indicate the reactions thus involved, this has been a secondary rather than a primary consideration in the selection and organization of the material. Some material has been included because it served certain of the other objectives mentioned in the introductory chapter, though for the most part these objectives are served also by the material primarily of significance in relation to the major objective.”
