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...
