Opis

The question of the symbolic structure of physics is implicitly involved in any discussion about the character of physical knowledge and the development of physical theories. Actually many discussions would greatly profit from an explicit reference to and an investigation of this question, and much confusion may be avoided in this way. A book directly addressing the use and character of symbols in physics may help provide a point of view which is in the back- ground of any consideration in the theory of knowledge and which is, to be sure, very relevant today, but - strangely enough - often seems to be missing as an explicit and central perspective in the present epistemological debates. The concept of symbol has different meanings. Its wide diffusion in various cultural fields such as religion, mythology, art, and psychoanalysis, constitutes the best proof of its semantic variety, but also of the danger of using it in too vague a way. We start here from the concept of symbol conceived in the general sense of a sign or a material medium which is able, on the one hand, to communicate mental or conceptual contents and, on the other hand, to des- ignate things or situations in the world. In this way symbols make it possible for human knowledge to "translate" the mental activity grasping the real- ity in conceptual frames, formal or natural languages, scientific propositions, theories and so on.

Recenzje

"The book has the important merit of calling our attention to the fundamental problem of sorting out what in physical theories comes from ourselves (the a priori, symbolic, conventional part) and what comes from nature, a question that we are far from having definitely solved." (International Studies in the Philosophy of Science, 17/1, 2003)

Blurb

This book tackles the question of the symbolic structure of physics, a topic which is implicit in any theory of knowledge, but one that often seems to be ignored as an explicit and central element in today's epistemological debates. The elucidation of this problem should benefit a number of ongoing discussions and can help to avoid much recurring confusion. The contributions to the book have been chosen so as to provide a coherent view, ultimately addressing the relation between the concepts used in science and the real world. The first part provides an introduction to the problem as it arises in physics, and to the modern history of symbols. The subject of the second part is the epistemological discussion taking place between physicists and philosophers about the role of symbols in our knowledge of Nature. The third part addresses key issues related to the methodology of physics and the character of its symbolic structures. The aim of this book is to provide a consistent, if not comprehensive, view, emphasizing aspects that are paradigmatic for the natural sciences as a whole.
