INTRODUCTION TO THE SERIES: SCIENCE ACROSS CULTURES: THE HISTORY OF NON-WESTERN SCIENCE In 1997, Kluwer Academic Publishers published the Encyclopaedia of the History of Science, Technology, and Medicine in Non-Western Cultures. The encyclopedia, a collection of almost 600 articles by almost 300 contributors, covered a range of topics from Aztec science and Chinese medicine to Tibetan astronomy and Indian ethnobotany. For some cultures, specific individuals could be identified, and their biographies were included. Since the study of non-Western science is not just a study of facts, but a study of culture and philosophy, we included essays on subjects such as Colonialism and Science, Magic and Science, the Transmission of Knowledge from East to West, Technology and Culture, Science as a Western Phenomenon, Values and Science, and Rationality, Objectivity, and Method. Because the encyclopedia was received with critical acclaim, and because the nature of an encyclopedia is such that articles must be concise and compact, the editors at Kluwer and I felt that there was a need to expand on its success. We thought that the breadth of the encyclopedia could be complemented by a series of books that explored the topics in greater depth. We had an opportunity, without such space limitations, to include more illustrations and much longer bibliographies. We shifted the focus from the general educated audience that the encyclopedia targeted to a more scholarly one, although we have been careful to keep the articles readable and keep jargon to a minimum. Before we can talk about the field of non-Western science, we have to define both non-Western and science. The term non-Western is not a geographical designation; it is a cultural one. We use it to describe people outside of the Euro-American sphere, including the native cultures of the Americas. The power of European and American colonialism is evident in the fact that the majority of the world's population is defined by what they are not. And in fact, for most of our recorded history the flow of knowledge, art, and power went the other way. In this series, we hope to rectify the lack of scholarly attention paid to most of the world's science. v VI INTRODUCTION TO THE SERIES As for defining science, if we wish to study science in non-Western cultures, we need to take several intellectual steps. First, we must accept that every culture has a science, that is, a way of defining, controlling, and predicting events in the natural world. Then we must accept that every science is legitimate in terms of the culture from which it grew. The transformation of the word science as a distinct rationality valued above magic is uniquely European. It is not common to most non-Western societies, where magic and science and religion can easily co-exist. The empirical, scientific realm of understanding and inquiry is not readily separable from a more abstract, religious realm. The first two books in the series are Astronomy Across Cultures: the History of Non-Western Astronomy, and Mathematics Across Cultures: the History of Non-Western Mathematics. Each includes about 20 chapters. Most deal with the topic as it is perceived by different cultures: Australian Aboriginal Astronomy, Native American Mathematics, etc. Each book also contains a variety of essays on related subjects, such as Astronomy and Prehistory, or East and West. The next four in the series will cover Medicine, Nature and the Environment, Chemistry and Alchemy, and Physics and Optics. We hope the series will be used to provide bqth factual information about the practices and practitioners of the sciences as well as insights into the world views and philosophies of the cultures that produced them. We hope that readers will achieve a new respect for the accomplishments of ancient civiliza tions and a deeper understanding of the relationship between science and culture.

I never believe that Kluwer is a large company, because of all the individual attention the staff gives me. I would also like to thank my colleagues at Hampshire College; I am so fortunate to be able to work with them. Special thanks go to Aaron Berman, Brian Schultz, and Gai Carpenter for recognizing the value of my work and giving me time to do it. And mostly I offer innumer able, unquantifiable thanks to Bob and Lisa and Tim.
