Scientists act within a social context and from a philosophical perspective that is inherently political. Whether they realize it or not, scientists always choose sides. The Dialectical Biologist explores this political nature of scientific inquiry, advancing its argument within the framework of Marxist dialectic. These essays stress the concepts of continual change and codetermination between organism and environment, part and whole, structure and process, science and politics. Throughout, this book questions our accepted definitions and biases, showing the self-reflective nature of scientific activity within society.

This volume contains some of Professor Wigner's more popular papers, which, in their diversity of subject and clarity of style, reflect the author's deep analytical powers and the remarkable scope of his interests. Included are articles on the nature of physical symmetry, invariance and conservation principles, the structure of solid bodies and of the compound nucleus, the theory of nuclear fission, the effects of radiation on solids, and epistemological problems of quantum mechanics. Other articles deal with the story of the first man-made nuclear chain reaction, the long-term prospects of nuclear energy, the problems of Big Science, and the role of mathematics in the natural sciences. In addition, the book contains statements of Wigner's convictions and beliefs, as well as memoirs of his friends, Enrico Fermi and John von Neumann.

This book was first published in 1980. Walter Ullmann made substantial contributions to many areas of medieval studies, and to those of papal history and cannon law particularly, which have been distinguished by quality and quantity alike. The bibliography of his published work included in this volume contains almost four hundred items. No less influential for generations of students have been his teaching and lecturing, especially at Leeds and from 1949 to 1978 at Cambridge. In Authority and Power friends and former pupils combined to mark his retirement from the Cambridge Chair of Medieval History, with each contributor writing on or near the subject originally studied under Professor Ullmann's supervision. The essays serve both to acknowledge a sense of shared indebtedness to Professor Ullmann and to indicate new approaches and developments, as they were at the time, in legal-historical scholarship. --
