Abstract

This book professes to give a semantic analysis of the main concepts of classical and quantum physics. The author holds that the task of philosophy of science is to explicate the meanings of scientific theories, laws, and hypotheses by formal reconstruction; semantic rules are a necessary part of such a reconstruction. Beginning with an extremely, indeed fatally, simplified treatment of the required concepts of logical syntax and semantics, he proceeds to discuss in non-technical language the concepts of the chief physical theories, and concludes with a description of the methodology of theory construction and confirmation. His only unusual thesis is that, contrary to what physicists tell us, models still essentially underlie all physical theories and constitute the link between theory and experiment on which must be based the semantic rules needed to supplement attempts at formal reconstruction. The strength of the book lies not in its semantic emphasis but in its stress on the hypothetico-deductive character of modern exact science, as opposed to the inductive accounts imputed to empiricists. --L.
