Those who are interested in the scientific method, its source, process, and results will find in this book a study of the remarkable ideas of Pierre Duhem, a man who has done important work in physics and the history of science. His The detailed ideas have influenced much logical thought in the United States. account herein begins with an orienting and non-technical introduction to the philosophy of science. Duhem’s ideas on the nature of physical theory are exposed and on this are built his conceptions of the detailed processes which are First, the elements are selected involved in the building up of physical theory. and represented by algebraic or Geometric symbols, then the formulation of The aim hypotheses accomplished by the process of mathematical deduction. of physical theory, according to Duhem’s conception, is stated as the representation and classification of experimental laws. Accordingly, there is given an exposition of his conception of the nature of experiment in physics and the From these are developed the principles governing the theories of physical laws. Here it is shown that it is impossible confrontation of experiment with theory. to construct a system of theory by the inductive method alone and that logic does not require that hypotheses should undergo, one by one, an experimental test, since isolated hypotheses cannot be tested, but only as a part of an extensive
