The essays and commentaries presented here are intended to strike a balance between the disciplines to which the Bar-Hillel Colloquium (formerly the Israel Colloquium) is dedicated. The historical and sociological vantage point is addressed in Krammick's and Mali's treatment of Priestley, in Vicker's and Feldhay's studies of the Renaissance occult and in Warnke's and Barasch's work on the imagination. From a philosophical angle several concepts, all material to the methodology of science, are taken up: rule following, by Smart and Margalit; analysis, by Ackerman, explanation, by Taylor; and the role of mathematics in physics, by Levy-Leblond and Pitowsky. In addition, the volume contains the proceedings of two symposia dedicated to two towering scientific figures: one celebrates Bohr's centennial, and the other examines the "other" Newton. The book should appeal to people whose interest or research is in the fields of philosophy, sociology and history of science, technology and medicine, as well as those interested in science education.

This is the second volume of Proceedings of the Israel Colloquium for the History, Philosophy and Sociology of Science. At the time that this preface is being written, the fourth annual series of lectures within the framework of the Israel Colloquium is already behind us and the fifth is underway. The Israel Colloquium thus has now not only a future to look forward to but also a past which is a source, of pride and pleasure for those who take part in this venture. The Israel Colloquium has, I believe, struck roots in the Israeli scientific and intellectual life, while drawing on the ever-increasing readiness of the international scientific and intellectual community for continuous support. As in the first volume, here too the papers presented, taken together, attempt a threefold representation of science and of the scientific activity: the historical, the social, and the systematic. A novel focal point in this volume is the treatment of some case studies illuminating historical, social, and philosophical aspects of medicine. Another center of gravity here is the Eddington Centennial Symposium which was a main event in the Collo quium activity of the 1982-83 series. This is a fitting place for me to report with sorrow the untimely death in the summer of 1984 of Solly G. Cohen, one of Israel's leading scientists, who is among the contributors to this volume."

The Israel Colloquium for the History, Philosophy and Sociology of Science presents before you its third volume of proceedings. The philosophy section of the volume has three main foci: the scientific explanation (Hempel and Ben-Menachem, Elster and Dascal); realism in science (Cohen and Zemach) and its implications for the problem of universals (Armstrong and Bar-Elli); and the question of demarcation: the dividing line between science and philosophy (KrUger), as well as the cognitive limits of science (Stent). There is no neat separation in this volume between essays on the history of science and those on the sociology of science, and perhaps properly so. Thus, Lenoir's contribution is a clear example of the way the two disciplines combine and interrelate. Joseph Ben-David's comment on this lecture was among the last things he wrote, knowing full well that his days were numbered. Reading his contribution imparts a strong sense of loss, the loss of a great sociologist and a wise man. Not only history, however, but also historiography is a subject for reflection in this volume (Freudenthal and Kerszberg). And, finally, a couple of articles convey the sense of fascination with science as a story (Heilbron, Hughes). We have by now come to expect from the investigations reported in the Israel Colloquium series not surface unity of theme and method, but rather an underlying common commitment and zest for the scientific enterprise at its best. The third volume hopes to join the first two in footing this bill.

This collection of essays presents cutting-edge research on a classic philosophical problem --- the link between reasoning and practice. The essays, by such well-known thinkers as Davidson, Scheffler, Sunstein, Dworkin, and Stroud, cover a range of issues raised by the move from thought to action. The book represents an inquiry into the very nature of reason, reasoning and reasons, rationale, rationalization, and rationality. These essays also connect philosophical thought with concrete issues in social life and political practice, thus, it will be of interest not only to philosophers, but also to political theorists, legal scholars, and any researcher interested in the practical applications of reason.

This collection is the first proceedings volume of the lectures delivered within the framework of the Israel Colloquium for the History, Philosophy and Sociology of Science, in its year of inauguration 1981-82. It thus marks the beginning of a new venture. Rather than attempting to express an ideology of the l}nity of science, this collection in fact aims at presenting a kaleidoscopic picture of the variety of views about science and within science. Three main disciplines come together in this volume. The first of scientists, the second of historians and sociologists of science, the third of philosophers interested in science. The scientists try to present the scientific body of knowledge in areas where the scientific adventure kindles the imagination of the culture of our time. At the same of course, they register their own reflections on the nature of this body time, of knowledge and on its likely course of future development. For the historians and sociologists, in contrast, science is there to be studied diachronically, as a process, on the one hand, and synchronically, as a social institution, on the other. As for the phil9sophers, finally, their contribution to this series is not meant to remain within the confines of what is usually seen as the philosophy of science proper, or to be limited to the analysis of the scientific mode of reasoning and thinking: it is allowed, indeed encouraged, to encompass alter native, and on occasion even competing, modes of thought."

Normal Rationality is a selection of the most important work of Edna Ullmann-Margalit, presenting some influential and widely admired essays alongside some that are not well known. She was an unorthodox and deeply original philosopher whose work illuminated the largest mysteries of human life. Much of her writing focuses on two fundamental questions. (1) How do people proceed when they cannot act on the basis of reasons, or project likely consequences? (2) How is social order possible? Ullmann-Margalit's answers, emphasizing what might be called biased rationality, are important not only for philosophy, but also for political science, psychology, sociology, cognitive science, economics (including behavioral economics), law, and even public policy. Ullmann-Margalit demonstrates that people have identifiable strategies for making difficult decisions, whether the question is small (what to buy at a supermarket) or big (whether to transform one's life in some large-scale way). She also shows that social dilemmas are solved by norms; that invisible-hand explanations take two identifiable (and dramatically different) forms; that trust can emerge in seemingly unpromising situations; and that considerateness is the foundation on which our relationships are organized in both the thin context of the public space and the intimate context of the family. One of the distinguishing features of Ullmann-Margalit's work is its close attention to the details of human experience, and its use of those details to offer fresh understandings of social phenomena. Her essays cast new light on a diverse assortment of problems in philosophy, social science, and individual lives.

This book provides an account of the emergence of norms. Put very crudely, the main thesis of this book is that certain types of norms are possible solutions to problems posed by certain types of social interaction situations. The problems are such that they inhere in the structure (in the game-theoretical sense of structure) of the situations concerned. Three types of paradigmatic situations are dealt with. They are referred to as Prisoners' Dilemma-type situations; co-ordination situations; and inequality (or partiality) situations. Each of them, it is claimed, poses a basic difficulty, to some or all of the individuals involved in them. Three types of norms, respectively, are offered as solutions to these situational problems. It is shown how, and in what sense, the adoption of these norms of social behaviour can indeed resolve the specified problems.

More than fifty years ago the discovery of scrolls in eleven caves beside the Dead Sea ignited the imagination of the world--and launched a vast academic field. Expectations abounded that the scrolls would reveal actual contemporaneous accounts of the birth of Christianity, perhaps even of the life of Jesus. The research that followed--its inner logic, and what its impassioned and often highly controversial theories reveal about the framing of facts and the interpreting of texts--is what interests philosopher Edna Ullmann-Margalit in this thoroughly absorbing book.

Since the inception of Dead Sea Scrolls research, a central theory has emerged. Known as the Qumran-Essene Hypothesis, it asserts that the scrolls belonged to the Essenes, a sect whose center was at the nearby site of Qumran. In "Out of the Cave," Ullmann-Margalit focuses on this theory and the vicissitudes of its career. Looking at the Essene connection, the archaeology of Qumran, and the sectarian nature of the scrolls community, she explores the different arenas, and ways, in which contesting theories of the scrolls do battle. In this context she finds fascinating examples of issues that exercise philosophers of science as well as the general public--issues that only amplify the already intrinsic interest of the Dead Sea scrolls.
