1. AIMS OF THE INTRODUCTION The systematic assessment of claims to knowledge is the central task of epistemology. According to naturalistic epistemologists, this task cannot be well performed unless proper attention is paid to the place of the knowing subject in nature. All philosophers who can appropriately be called 'naturalistic epistemologists' subscribe to two theses: (a) human beings, including their cognitive faculties, are entities in nature, inter acting with other entities studied by the natural sciences; and (b) the results of natural scientific investigations of human beings, particularly of biology and empirical psychology, are relevant and probably crucial to the epistemological enterprise. Naturalistic epistemologists differ in their explications of theses (a) and (b) and also in their conceptions of the proper admixture of other components needed for an adequate treatment of human knowledg- e.g., linguistic analysis, logic, decision theory, and theory of value. Those contributors to this volume who consider themselves to be naturalistic epistemologists (the majority) differ greatly in these respects. It is not my intention in this introduction to give a taxonomy of naturalistic epistemologies. I intend only to provide an overview which will stimulate a critical reading of the articles in the body of this volume, by facilitating a recognition of the authors' assumptions, emphases, and omissions."

The first part of this third volume of Wigner's Collected Works is devoted to his analysis of symmetries in quantum mechanics, of the relativistic wave equations, of relativistic particle theory, and of field theory. It is introduced by the masterly annotation of Arthur S. Wightman. Abner Shimony annotates the second part where the reader will find Wigner's contributions to the foundations of quantum physics and to the problems of measurement.

This book is for physicists, historians and philosophers of physics as well as students seeking an introduction to ongoing debates in relativistic and quantum physics. This title covers the recent debates on the emergence of relativity and quantum theory. It includes chapters with an introductory character, comprehensible to students and science teachers. It strengthens the bonds between the communities of scientists, historians, and philosophers.
