Inside this Book – Economic history is concerned with the description and the analysis of the mutual transformations taking place between human societies and their environment. The study of costs and prices is important, and the institutional structure of organized social life demands careful attention, but the basic problems of economic history lie in the field of the management of resources. We are constantly faced with the need of describing the resources effectively available to a given society over an appreciable period of time—the remote future no less than the most immediate present. The quantitative analysis of economic activities requires study of the processes and accomplishments of the system of production in physical units as well as in value units. Economic history is therefore intimately concerned with the explicit geographic environment, and with the techniques by which resources are utilized at any given moment. The economic historian must use with care the broader results of both the geographers and the technologists. The dependence of economic history upon geography has long been recognized, but the importance of an effective understanding of technologic development is not so generally appreciated. Furthermore, little attention is commonly given to the relation between the geographic environment and the technology that makes the environment useful.
Inside this book –A History Of Mechanical Inventions PDF Book by Abbott Payson Usher – The conventions of historical writing have always stressed presentation in narrative form. Criticism plays its part in the study of documents, in the search for explicit evidence of the chronology of events, and in the elimination of conscious or unconscious misinterpretation of motives and acts. The implied antithesis between scientific analysis and historical narrative has, however, constantly obscured the importance of analytic procedures in history, though for more than a century there has been a steady development of techniques of analysis that are closely comparable with the techniques of the sciences in all their operational details. Despite some minor differences in the character of the problems involved, we must now assume that the logical and epistemological problems faced by the historian are not essentially different from the problems of the scientist. If we are concerned with the development of an institution like Parliament in England, significant understanding of the development requires accurate analysis of many changes in form and function. Changes in function require new forms; new forms foster further changes in function. A large measure of identity was preserved over a very long period, despite the magnitudes of changes in function. The history of Parliament can doubtless be presented most effectively and most compactly in narrative form, but the narrative must rest upon a great deal of careful analytic work. The problems of growth and change involved in the history of Parliament are neither more nor less complex than the problems presented by paleontology or genetics. The materials are different; the problems are the same.
