In this book, sixteen leading scholars address themselves to providing as full an account of medieval science as current knowledge permits. Designed to be introductory, the authors have directed their chapters to a beginning audience of diverse readers.

By explaining how to sire multicolored horses, produce nuts without shells, and create an egg the size of a human head, Giambattista Della Porta's Natural Magic (1559) conveys a fascination with tricks and illusions that makes it a work difficult for historians of science to take seriously. Yet, according to William Eamon, it is in the "how-to" books written by medieval alchemists, magicians, and artisans that modern science has its roots. These compilations of recipes on everything from parlor tricks through medical remedies to wool-dyeing fascinated medieval intellectuals because they promised access to esoteric "secrets of nature." In closely examining this rich but little-known source of literature, Eamon reveals that printing technology and popular culture had as great, if not stronger, an impact on early modern science as did the traditional academic disciplines.

This volume in the highly respected Cambridge History of Science series is devoted to the history of science in the Middle Ages from the North Atlantic to the Indus Valley. Medieval science was once universally dismissed as non-existent - and sometimes it still is. This volume reveals the diversity of goals, contexts and accomplishments in the study of nature during the Middle Ages. Organized by topic and culture, its essays by distinguished scholars offer the most comprehensive and up-to-date history of medieval science currently available. Intended to provide a balanced and inclusive treatment of the medieval world, contributors consider scientific learning and advancement in the cultures associated with the Arabic, Greek, Latin and Hebrew languages. Scientists, historians and other curious readers will all gain a new appreciation for the study of nature during an era that is often misunderstood.

Medieval science and technology was firmly rooted in Aristotelian explanations of the physical world. This book begins by introducing the basic concepts of the classical tradition, and explains how these ideas were promulgated by the ancient Greeks, preserved and commented on by the great Muslim scholars of the early middle ages, and finally transmitted to western Europe as that region began to grow and expand around 1100 C.E. Specific avenues of inquiry such as astronomy and astrology, optics, chemistry and alchemy, zoology, geography, and medicine are described on their own terms. Rounding out the work is a discussion of the many technological innovations of the medieval age, such as mechanical clocks, firearms, and the blast furnace, that profoundly altered the course of European and world history. Biographical sketches provide insight into the lives and accomplishments of 20 men and women, Christian, Muslim, and pagan, whose works profoundly shaped the era's scientific spirit. Eleven annotated key primary documents afford a fascinating glimpse into how the best minds of the time posed their questions and their answers. An annotated timeline, glossary of terms, several illustrations, and an annotated bibliography round out the work. Medieval scientists, or natural philosophers, as they were then called, were powerfully influenced by the authority of older traditions, including Christianity and scientific ideas dating back to Plato, Aristotle, and Ptolemy. Yet their respect for these traditions was balanced by an equal respect for reason and the spirit of inquiry. Religious faith, far from dampening scientific and technological innovation, actually buttressed their efforts to understand the natural world as it was generally taken for granted that knowledge acquired through reason would harmonize with religious beliefs. While medieval science and technology did not seek to overthrow the prevailing worldviews of the time, their accomplishments did lay the groundwork for the scientific revolution and European global expansion of the early modern age.

For this book, we have selected papers from symposia and contributed sessions at the fourth biennial meeting of the Philosophy of Science Association, held at the University of Notre Dame on November 1-3, 1974. The meeting was lively and well-attended, and we regret that there was no way to record here the many stimulating discussions after the papers and during the informal hours. We also regret that we had in sufficient space for all the contributed papers. Even more, some of the symposia were not available: those on systems and decision theory (c. W. Churchman, P. Suppes, I. Levi), and on the Marxist philosophy of science (M. W. Wartofsky, R. S. Cohen, E. N. Hiebert). Unhappily several individual contributions to other symposia were likewise not available: I. Velikovsky in the session on his own work and the politics of science, D. Finkelstein in the session on quantum logic. Memorial minutes were read for Alan Ross Anderson (prepared by Nuel Belnap) and for Imre Lakatos (prepared by Paul Feyerabend). They initiate this volume of philosophy of science in the mid-seventies.
