The Swedish predecessor of this book, Introduktion till Vetenskapsteorin, grew out of an urgently felt need when I was teaching philosophy of science for students of engineering, physics, biology, social science, medicine and nursing. These students have normally no philosophical background and quite often little knowledge of
history of science. This book has now been in print for 15 years, and three editions and its relative success in Sweden have encouraged me to make a translation to English in the hope that a wider audience also will ?nd it useful. This book is not merely a translation of the Swedish book; I have also made some changes. First, Ties Niessen suggested a slight reshuf?e of the chapters and an addition of a short Chap. 14, with some actual and forward-looking re?ections, which I have done. Second, I have rewritten Sect. 10.7, since I have come to
understand laws better. Third, I have made a great number of minor changes as a result of comments and suggestions from two anonymous referees. Their advice was very helpful. The prime goal for a ?rst course in philosophy of science should be, I believe, to convey an understanding of what science is: how it has developed, what its core traits are, how to distinguish between science and pseudoscience and to know what
a scienti?c attitude is. In such an endeavour it is common and natural to concentrate on the development
and core traits of natural science. However, students and scholars within the social sciences and humanities often think that these sciences differ profoundly from natural science and that the lessons from Galilei, Newton and other natural scientists are not relevant for them.
