The Fifth International Congress of Logic, Methodology and Philosophy of Science was held at the University of Western Ontario, London, Canada, 27 August to 2 September 1975. The Congress was held under the auspices of the International Union of History and Philosophy of Science, Division of Logic, Methodology and Philosophy of Science, and was sponsored by the National Research Council of Canada and the University of Western Ontario. As those associated closely with the work of the Division over the years know weIl, the work undertaken by its members varies greatly and spans a number of fields not always obviously related. In addition, the volume of work done by first rate scholars and scientists in the various fields of the Division has risen enormously. For these and related reasons it seemed to the editors chosen by the Divisional officers that the usual format of publishing the proceedings of the Congress be abandoned in favour of a somewhat more flexible, and hopefully acceptable, method of pre sentation. Accordingly, the work of the invited participants to the Congress has been divided into four volumes appearing in the University of Western Ontario Series in Philosophy of Science. The volumes are entitled, Logic, Foundations of Mathematics and Computability Theory, Foun dational Problems in the Special Sciences, Basic Problems in Methodol ogy and Linguistics, and Historical and Philosophical Dimensions of Logic, Methodology and Philosophy of Science."

The idea to produce the current volume was conceived by Jiirgen Mittelstrass and Robert E. Butts in 1978. Idealist philosophers are wrong about one thing: the temporal gap separating idea and reality can be very long indeed - even ten or so years Problems of timing were joined by personal problems and by the pressure of other professional commitments. Fortunately, James Brown agreed to cooperate in the editing of the volume; the infusion of his usual energy, good judgement and good-natured promptness saved the volume and made its produc tion possible. Despite the delays, the messages of the papers included in the book have not gone stale. An extremely worthwhile exercise in international philosophical cooperation has come to fruition; the German constructivist philosophical position is here represented in papers in English that will make its contemporary importance available to a larger audience. The editors owe thanks to many persons. All involved in the project owe much to the interest and support of Nicholas Rescher, a friend of the undertaking from the time of its inception. My review of the translations was helped immensely by Andrea Purvis' careful copy editing of the typescript. Most of all, however, we owe gratitude and admiration for the tireless efforts on behalf of this enterprise to Jiirgen Mittelstrass."

For 35 years, the critical and creative writings of Robert E. Butts have been a notable and welcome part of European and North American philosophy. A few years ago, James Robert Brown and Jiirgen Mittelstrass feted Professor Butts with a volume entitled An Intimate Relation (Boston Studies vol. 116, 1989), essays by twenty-six philosophers and historians of the sciences. And that joining of philosophers and historians was impressive evidence of the 'intimate relation' between historical illumination and philosophical understanding which is characteristic of Butts throughout his work. Not alone, Butts has been, and is, one of this generation's most incisive thinkers, devoted to responsible textual scholarship and equally responsible imaginative interpretation. Brown and Mittelstrass said that "throughout his writings, science, its philosophy, and its history have been treated as a seamless web," and I would add only that philosophy per se is a part of the web too. Here in this book before us are the results, a lovely collection from the work of Robert Butts, who is for so many of his colleagues, students and readers, Mr. HPS, the model philosophical historian and historical philosopher of the sciences. July 1993 Robert S. Cohen Center for Philosophy and History of Science, Boston University TABLE OF CONTENTS BIBLIOGRAPHICAL NOTE IX INTRODUCTION Xl PART I EARLY MODERN PHILOSOPHY OF SCIENCE 1 1. Some tactics in Galileo's propaganda for the mathematization of scientific experience 3 2.

Robert E. Butts (1928-1997) was a philosopher and historian of science whose central concerns were the distinction between the rational and the irrational. He viewed scientific rationality as our major defence against the various conditions that encourage witch hunts and similar outbursts of irrationality, with all their attendant pain and terror. Butts saw himself as a pragmatic realist, combining what he took to be the best aspects of logical empiricism with a historically informed pragmatism, deeply appreciative of the methods of science, trying to describe a kind of rationality essential in the struggle to preserve human values. This volume gathers previously unpublished essays and lectures with some previously published, thematically related essays. It includes essays and lectures on philosophical aspects of the European witch hunt, on scientific rationality and methodology, and on the relationships between science and philosophy exhibited in the writings of such historically significant figures as Leibniz, D'Alembert, Hume, Kant, Carnap and Kuhn.

This is a book about dreaming and knowing, and about thinking that one can ascertain the difference. It is a book about the Bernards of the world who would have us believe that there is a humanly uncreated world existing en Boi that freely dis closes its forever fixed ontology, even though they too must accept that -many of the worlds we make as we try to under stand ourselves are counterfeit. It is a book about the real estate of the human mind. The book is about Leibniz and Kant, and about methods of science. It is also about what is now called pseudo-science. It tries to show how Kant struggled to mark the limits of the humanly knowable, and how thi s strug gle involved him in trying to answer questions of importance then and now. Some are philosophers' questions: the epistemo logical status of mathematics, the role of space and time in knowing, the nature of the conceptual constraints on our ef forts to hypothesize the possible. Some are questions of per ennial human interest: Can spirits exist? How is the soul re lated to the body? How can we legitimately talk about God, if at all? Finally, Kant teaches that these are all questions bearing on our entitlements in claiming to know. Leibniz fashioned a way of talking about nature and super nature that I call the Double Government Methodology."

The papers in this volume are offered in celebration of the 200th anni versary of the pub 1 i cat i on of Inmanue 1 Kant's The MetaphysicaL Foundations of NatupaL Science. All of the es says (including the Introduction) save two were written espe ci ally for thi s volume. Gernot Bohme' s paper is an amended and enlarged version of one originally read in the series of lectures and colloquia in philosophy of science offered by Boston University. My own paper is a revised and enlarged version (with an appendix containing completely new material) of one read at the biennial meeting of the Philosophy of Sci ence Association held in Chicago in 1984. Why is it important to devote this attention to Kant's last published work in the philosophy of physics? The excellent essays in the volume will answer the question. I will provide some schematic com ments designed to provide an image leading from the general question to its very specific answers. Kant is best known for hi s monumental Croitique of Pure Reason and for his writings in ethical theory. His "critical" philosophy requires an initial sharp division of knowledge into its theoretical and practical parts. Moral perfection of attempts to act out of duty is the aim of practical reason. The aim of theoretical reason is to know the truth about ma terial and spiritual nature."

The essays in this volume (except for the contribution of Dr. Le Grand) are extremely revised versions of papers originally delivered at a workshop on Galileo held in Blacksburg, Virginia in October, 1975. The meeting was organized by Professor Joseph Pitt and sponsored by the Department of Philosophy and Religion, The College of Arts and Sciences, and the Division of Research of Virginia Polytechnic Institute and State University. The papers that follow deal with problems OIf Galileo's philosophy of science, specific and general problems connected with his methodology, and with historical and conceptual questions concerning the relationship of his work to that of contemporaries and both earlier and later scientists. New perspectives take many forms. In this book the 'newness' has, for the most part, two forms. First, in the papers by Wisan, Shea, Le Grand and Wallace (the concerns will also appear in some of the other contributions), greatly enriched historical discoveries of how Galileo's science and its method ology developed are provided. It should be stressed that these papers are attempts to recapture a deep sense of the kind of science Galileo was creating. Other papers in the volume, for example, those by McMullin, Machamer, Butts and Pitt, underscore the importance of this historical venture by discussing various aspects of the philosophical background of Galileo's thought. The historical and philosophical evaluations and analyses compliment one another."

This volume grew out of the papers and comments presented at the Fifth University of Western Ontario Philosophy Colloquium, October 31- November 2, 1969. The colloquium papers were delivered by P. Suppes, R. B. Braithwaite, C. W. Churchman, and J. S. Minas. Comments are provided from others attending the colloquium, with one reply by P. Suppes. Also included are papers recently published elsewhere by A. Michalos, P. Fishburn and H. -N. Castaneda. The editors express thanks to these authors and to the editors of the following respective journals for per mission to publish: Theory and Decision, Synthese, and Critica. Finally, there is an extensive bibliography of decision theory, vis-a. -vis science and values. The editors wish to thank the officers of the University of Western Ontario for making the colloquium possible.

This volume includes Whewell's seminal studies of the logic of induction (with his critique of Mill's theory), arguments for his realist view that science discovers necessary truths about nature, and exercises in the epistemology and ontology of science. The book sets forth a coherent statement of a historically important philosophy of science whose influence has never been greater: every one of Whewell's fundamental ideas about the philosophy of science is presented here.
