Ptolemy's Almagest shares with Euclid's Elements the glory of being the scientific text longest in use. From its conception in the second century up to the late Renaissance, this work determined astronomy as a science. During this time the Almagest was not only a work on astronomy; the subject was defined as what is described in the Almagest. The cautious emancipation of the late middle ages and the revolutionary creation of the new science in the 16th century are not conceivable without reference to the Almagest. This text lifted European astronomy to the high standard of knowledge on which the new science flourished. Before, the Ptolemaic models of the orbits of the sun, the moon, and the planets had been refined by Arabic astronomers. They provided the structural elements with which Copernicus and Kepler ushered in the era of modern astronomy. The Almagest survived the destruction of its epicyclic representation of the planetary orbits in the conceptual traces left behind in the theories of its successors. The clear separation of the sidereal from the tropical year, the celestial coordinate systems, the concepts of time, the forms of the constellations, and brightness classifications of celestial objects are, among many other things, still part of the astronomical canon even today.

George Berkeley was considered "the most engaging and useful man in Ireland in the eighteenth century." This hyperbolic statement refers both to Berkeley's life and thought; in fact, he always considered himself a pioneer called to think and do new things. He was an empiricist well versed in the sciences, an amateur of the mechanical arts, as well as a metaphysician; he was the author of many completely different discoveries, as well as a very active Christian, a zealous bishop and the apostle of the Bermuda project. The essays collected in this volume, written by some leading scholars, aim to reconstruct the complexity of Berkeley's figure, without selecting "major" works, nor searching for "coherence" at any cost. They will focus on different aspects of Berkeley's thought, showing their intersections; they will explore the important contributions he gave to various scientific disciplines, as well as to the eighteenth-century philosophical and theological debate. They will highlight the wide influence that his presently most neglected or puzzling books had at the time; they will refuse any anachronistical trial of Berkeley's thought, judged from a contemporary point of view.

The distinction between the contexts of discovery and justification has had a turbulent career in philosophy of science. At times celebrated as the hallmark of philosophical approaches to science, at times condemned as ambiguous, distorting, and misleading, the distinction dominated philosophical debates from the early decades of the twentieth century to the 1980s. Until today, it informs our conception of the content, domain, and goals of philosophy of science. It is due to this fact that new trends in philosophy of experimentation and history and sociology of science have been marginalized by traditional scholarship in philosophy. To acknowledge properly this important recent work we need to re-open the debate about the nature, development, and significance of the context distinction, about its merits and flaws. The contributions to this volume provide close readings and detailed analyses of the original textual sources for the context distinction.

In recent decades, there has been much scholarly controversy as to the basic ontological commitments of the philosopher Gottfried Wilhelm Leibniz (1646-1716). The old picture of his thought as strictly idealistic, or committed to the ultimate reduction of bodies to the activity of mind, has come under attack, but Leibniz's precise conceptualization of bodies, and the role they play in his system as a whole, is still the subject of much controversy. One thing that has become clear is that in order to understand the nature of body in Leibniz, and the role body plays in his philosophy, it is crucial to pay attention to the related concepts of organism and of corporeal substance, the former being Leibniz's account of the structure of living bodies (which turn out, for him, to be the only sort of bodies there are), and the latter being an inheritance from the Aristotelian hylomorphic tradition which Leibniz appropriates for his own ends. This volume brings together papers from many of the leading scholars of Leibniz's thought, all of which deal with the cluster of questions surrounding Leibniz's philosophy of body.

Although the name Pithecanthropus is now seldom used, there are few who study the origin of our species who will fail to recognise the historical place of the usage and its association with Eugene Dubois. During the last thirty or forty years, Australopithecus and its African context has tended to draw attention from the early work on our origins in Java. It is now increasingly common to hear the term 'pithecanthropine' used only to indicate the Asian or Far Eastern examples of Homo erectus which, although probably derived from African ancestry, have some features that in the opinion of some experts may justify their being considered distinctive. This discussion is not within the pages that follow which deal extensively with the work of Eugene Dubois. He was an extraordinary man who did as much as any person since to put the great antiquity of our ancestors firmly in the public domain. Dubois became involved with the study of human origins from a medical and anatomical background as have many since. The jealousies and professional pressures that we think of as a phenomenon of the post-war years were clearly a major factor in deciding the future of his career.

A follow-up to the volume "Discovering the Principles of Mechanics 1600-1800. Essays by David Speiser" (Birkhauser 2008), this volume contains the essays of David Speiser on relationships between science, history of science, history of art and philosophy.

This book has evolved out of a colloquium entitled "The Reception of the Galilean Science of Motion;' held at Amsterdam on 5-7 July 2000. It was our intention as the organizers to bring together historians of science interested in Galileo's science of motion, its ramifications in seventeenth-century Europe, and its impact on what Anneliese Maier and E. J. Dijksterhuis have labeled the "mechanization of the world picture. " Funding for the conference was provided by the Royal Netherlands Academy of Arts and Sciences, which honored our proposal for an Academy Colloquium. We should also like to thank Ap de Wit, Martine Wagenaar, and Ine van den Heuvel from the Royal Academy for the careful and reliable administrative organization of the colloquium. Through a generous grant (no. 200-22-295), the Netherlands Organization for Scientific Research ( NWO) allowed the Center for Medieval and Renaissance Natural Philosophy at Nijmegen University to act as the colloquium's second sponsor. All papers that were read at the colloquium have been strongly modified for publication. It is hoped that the resulting articles display even more coherence and unity than the colloquium did, while at the same time retaining something of its spirit and diversity. In addition to the authors whose articles are published here, the following scholars also participated in the discussions: Constance Blackwell, Hans Bots, Henk Braakhuis, Wiep van Bunge, Dirk-Jan Dekker, Fokko-Jan Dijksterhuis, Juliette van den Elsen, Fran'Tois de Gandt, Christoph Luthy, Olaf Pluta, Thomas Settle, Theo Verbeek, and Liesbeth de Wreede.

The year 2007 marks the 300th anniversary of the birth of one of the Enlightenment's most important mathematicians and scientists, Leonhard Euler. This volume is a collection of 24 essays by some of the world's best Eulerian scholars from seven different countries about Euler, his life and his work.
Some of the essays are historical, including much previously unknown information about Euler's life, his activities in the St. Petersburg Academy, the influence of the Russian Princess Dashkova, and Euler's philosophy. Others describe his influence on the subsequent growth of European mathematics and physics in the 19th century. Still others give technical details of Euler's innovations in probability, number theory, geometry, analysis, astronomy, mechanics and other fields of mathematics and science.
- Over 20 essays by some of the best historians of mathematics and science, including Ronald Calinger, Peter Hoffmann, Curtis Wilson, Kim Plofker, Victor Katz, Ruediger Thiele, David Richeson, Robin Wilson, Ivor Grattan-Guinness and Karin Reich
- New details of Euler's life in two essays, one by Ronald Calinger and one he co-authored with Elena Polyakhova
- New information on Euler's work in differential geometry, series, mechanics, and other important topics including his influence in the early 19th century

This book provides a chronological introduction to modern atomic theory, which represented an attempt to reconcile the ancient doctrine of atomism with careful experiments-performed during the 19th century-on the flow of heat through substances and across empty space. Included herein are selections from classic texts such as Carnot's Reflection on the Motive Power of Fire, Clausius' Mechanical Theory of Heat, Rutherford's Nuclear Constitution of Atoms, Planck's Atomic Theory of Matter and Heisenberg's Copenhagen Interpretation of Quantum Theory. Each chapter begins with a short introduction followed by a reading selection. Carefully crafted study questions draw out key points in the text and focus the reader's attention on the author's methods, analysis and conclusions. Numerical and laboratory exercises at the end of each chapter test the reader's ability to understand and apply key concepts from the text. Heat, Radiation and Quanta is the last of four volumes in A Student's Guide through the Great Physics Texts. The book comes from a four-semester undergraduate physics curriculum designed to encourage a critical and circumspect approach to natural science while at the same time preparing students for advanced coursework in physics. This book is particularly suitable as a college-level textbook for students of the natural sciences, history or philosophy. It might also serve as a textbook for advanced high-school or home-schooled students, or as a thematically-organized source-book for scholars and motivated lay-readers. In studying the classic scientific texts included herein, the reader will be drawn toward a lifetime of contemplation.

Charles Bonnet began his career as a naturalist, from an early age establishing a reputation as a careful observer. It is for those youthful observations, as well as for some suggestive speculations proposed relative to this field, that he is best remembered in English-speaking countries: regarding the taxonomic de mands of natural history he refurbished the idea of a chain of beings; regarding the question of generation he marshaled evidence in support of preforma tion theory; and regarding the analysis of the physiology of the nervous system he advanced a theory that individual nerve fibers receive and retain specific sensations. Following his loss of eyesight in his mid-twenties Bonnet entered a more reflective period, turning to philosophy and pondering the nature of human understanding - considerations he had formerly disdained, but that now seemed a natural outgrowth of his reflections on nature. This essay focuses on the philosophical and psychological works of the later period, the period in which he wrote all his major books. By giving these writings a broader exposure it has been one of my hopes that Bonnet's audience would also be broadened, releasing him, so to speak, from the charge of historians of science so that he might fmd his way, in general books on the "Enlightenment," from scattered footnotes into the texts themselves."

This book is the final outcome of two projects. My first project was to publish a set of texts written by Schrodinger at the beginning of the 1950's for his seminars and lectures at the Dublin Institute for Advanced Studies. These almost completely forgotten texts contained important insights into the interpretation of quantum mechanics, and they provided several ideas which were missing or elusively expressed in SchrOdinger's published papers and books of the same period. However, they were likely to be misinterpreted out of their context. The problem was that current scholarship could not help very much the reader of these writings to figure out their significance. The few available studies about SchrOdinger's interpretation of quantum mechanics are generally excellent, but almost entirely restricted to the initial period 1925-1927. Very little work has been done on Schrodinger's late views on the theory he contributed to create and develop. The generally accepted view is that he never really recovered from his interpretative failure of 1926-1927, and that his late reflections (during the 1950's) are little more than an expression of his rising nostalgia for the lost ideal of picturing the world, not to say for some favourite traditional picture. But the content and style of Schrodinger's texts of the 1950's do not agree at all with this melancholic appraisal; they rather set the stage for a thorough renewal of accepted representations. In order to elucidate this paradox, I adopted several strategies.

Sinceits founding by Jacques Waardenburg in 1971, Religion and Reason has been a leading forum for contributions on theories, theoretical issues and agendas related to the phenomenon and the study of religion. Topics include (among others) category formation, comparison, ethnophilosophy, hermeneutics, methodology, myth, phenomenology, philosophy of science, scientific atheism, structuralism, and theories of religion. From time to time the series publishes volumes that map the state of the art and the history of the discipline.

This book presents new insights into Freud's famous "discovery" of the unconscious and the subsequent development of psychoanalytic theories. The authors explore the original context in which these ideas arose and the central debate about mind as matter or something that transcends matter. In the course of this examination, it is demonstrated that Freud was influenced not only by the 19th century scientific milieu, but also by ancient cultures. While it is known that Freud was an avid collector of ancient artifacts and generally interested in these older cultures, this book systematically investigates their profound effect on his thinking and theorizing. Two major influences, Egyptian mythology and Jewish mysticism are analyzed in terms of similarities to Freud's emerging ideas about the mind and its diseases. To further this line of investigation, Bakan supplies an illuminating discussion of what it means to interpret. Taken from the viewpoint that interpretation involves an u

A comprehensive historical review of the debates surrounding women's contributions and roles in science, with emphasis on women's access to education, training, and professional careers. This remarkable work illuminates the debates surrounding women's involvement with science throughout history, covering a broad range of disciplines. Unlike a biographical compendium of great scientists, it examines the question posed throughout history: Are women capable of doing science? Whether people have the right to even ask the question is germane to the debate itself. The coverage discusses Hypatia, the first female scientist about whom we have information; examines the contradictory behavior of the church in the treatment of women during the medieval era; and covers the 17th century debates over women's education. It examines women physicians, discusses feminism and science, and delves into why there are so few women in science-even today. The debate that began during the time of Plato and Aristotle continues to this day. Each chapter features a central theme or controversy, such as the Querelle des Femmes, the professionalization of science, and the exclusion of women from medicine Includes a bibliography of primary and secondary sources divided into subsections based on topic, a complete subject index, and illustrations of the major female figures throughout the history of science

This book offers a comprehensive study of the views of ancient philosophers on mental disorders. Relying on the original Greek and Latin textual sources, the author describes and analyses how the ancient philosophers explained mental illness and its symptoms, including hallucinations, delusions, strange fears and inappropriate moods and how they accounted for the respective roles of body and mind in such disorders. Also considered are ethical questions relating to mental illness, approaches to treatment and the position of mentally ill people in societies of the times.

The volume opens with a historical overview that examines ancient medical accounts of mental illness, from Hippocrates' famous Sacred Disease to late antiquity medical authors. Separate chapters interpret in detail the writings of Plato, Aristotle, Galen and the Stoics and a final chapter summarises the views of various strains of Scepticism, the Epicurean school and the Middle and Neo-Platonists.

Offering an important and useful contribution to the study of ancient philosophy, psychology and medicine. This volume sheds new light on the history of mental illness and presents a new angle on ancient philosophical psychology.

When Columbus first returned to Spain from the Caribbean, he dazzled King Ferdinand and Queen Isabella with exotic parrots, tropical flowers, and bits of gold. Inspired by the promise of riches, countless seafarers poured out of the Iberian Peninsula and wider Europe in search of spices, treasure, and land. Many returned with strange tales of the New World.

Curiosity began to percolate through Europe as the New World s people, animals, and plants ruptured prior assumptions about the biblical description of creation. The Church, long fearful of challenges to its authority, could no longer suppress the mantra Dare to know

Noblemen began collecting cabinets of curiosities; soon others went from collecting to examining natural objects with fresh eyes. Observation led to experiments; competing conclusions triggered debates. The foundations for the natural sciences were laid as questions became more multifaceted and answers became more complex. Carl Linneaus developed a classification system and sent students around the globe looking for specimens. Museums, botanical gardens, and philosophical societies turned their attention to nature. National governments undertook explorations of the Pacific.

Eminent historian Joyce Appleby vividly recounts the explorers triumphs and mishaps, including Magellan s violent death in the Philippines; the miserable trek of the new Argonauts across the Andes on their mission to determine the true shape of the earth; and how two brilliant scientists, Alexander Humboldt and Charles Darwin, traveled to the Americas for evidence to confirm their hypotheses about the earth and its inhabitants. Drawing on detailed eyewitness accounts, Appleby also tells of the turmoil created in the all societies touched by the explorations.

This sweeping, global story imbues the Age of Discovery with fresh meaning, elegantly charting its stimulation of the natural sciences, which ultimately propelled Western Europe toward modernity."

This work counters historiographies that search for the origins of modern science within the experimental practices of Europe 's first scientific institutions, such as the Cimento. It proposes that we should look beyond the experimental rhetoric found in published works, to find that the Cimento academicians were participants in a culture of natural philosophical theorising that existed throughout Europe.

and less as the emanation unden\'ent radioactive decay, and it became motion less after about 30 seconds. Since this process was occurring very rapidly, Hahn and Sackur marked the position of the pointer on a scale with pencil marks. As a timing device they used a metronome that beat out intervals of approximately 1. 3 seconds. This simple method enabled them to determine that the half-life of the emanations of actinium and emanium were the same. Although Giesel's measurements had been more precise than Debierne's, the name of actinium was retained since Debierne had made the discovery first. Hahn now returned to his sample of barium chloride. He soon conjectured that the radium-enriched preparations must harbor another radioactive sub stance. The liquids resulting from fractional crystallization, which were sup posed to contain radium only, produced two kinds of emanation. One was the long-lived emanation of radium, the other had a short life similar to the emanation produced by thorium. Hahn tried to separate this substance by adding some iron to the solutions that should have been free of radium, but to no avail. Later the reason for his failure became apparent. The element that emitted the thorium emanation was constantly replenished by the ele ment believed to be radium. Hahn succeeded in enriching a preparation until it was more than 100,000 times as intensive in its radiation as the same quantity of thorium."

twentieth-century literature about the distinction between explanation and und- standing)? Second, can we do justice to a particular writer's notion of that category by taking at face value what he writes about his own motivation for adopting it? In response to both types of questions, there is by now a consensus amongst many historians of science and of philosophy that (a) intellectual history - like other kinds of history - has to be careful not to uncritically adopt actors' categories, and (b) more generally, even the actors' own thinking about a particular issue has to be contextualized vis-a-vis their other intellectual commitments and interests, as well as the complex conditions that make the totality of their commitments possible. Such conditions include cognitive as well as practical, institutional, and cultural factors. The articles in this volume respond to these challenges in several ways. For example, one author (Christopher Pincock) seeks to read some of the nineteen- century philosophical writings about Erklaren and Verstehen as standing for a more fundamental problem, which he terms the problem of the "unity of experience.""

The articles in this collection were all selected from the first five volumes of the Journal of Dialectics of Nature published by the Chinese Academy of Sciences between 1979 and 1985. The Journal was established in 1979 as a comprehensive theoretical publication concerning the history, philosophy and sociology of the natural sciences. It began publication as a response to China's reform, particularly the policy of opening to the outside world. Chinese scholars began to undertake distinctive, original research in these fields. This collection provides a cross-section of their efforts during the initial phase. To enable western scholars to understand the historical process of this change in Chinese academics, Yu Guangyuan's On the Emancipation of the Mind' and Xu Liangying's Essay on the Role of Science and Democracy in Society' have been included in this collection. Three of the papers included on the philosophy of science are discussions of philosophical issues in cosmology and biology by scientists themselves. The remaining four are written by philosophers of science and discuss information and cognition, homeostasis and Chinese traditional medicine, the I Ching (Yi Jing) and mathematics, etc. Papers have been selected on the history of both classical and modern science and technology, the most distinctive of which are macro-comparisons of the development of science in China and the west. Some papers discuss the issue of the demarcation of periods in the history of science, the history of ancient Chinese mathematics, astronomy, metallurgy, machinery, medicine, etc. Others discuss the history of modern physics and biology, the history of historiography of science in China and thehistory of regional development of Chinese science and technology. Also included are biographies of three post-eighteenth-century Chinese scholars, Li Shanlan (1811-1882), Hua Hengfang (1833&endash;1902), and Cai Yuanpei (1868&endash;1940), who contributed greatly to the introduction of western science and scholarship to China. In addition, three short papers have been included introducing the interactions between Chinese scholars and three great western scientists, Niels Bohr, Norbert Wiener, and Robert A. Millikan.
