The essays in this volume grew out of a seminar examining the possibility of the emergence of a new consensus in the philosophy of science. While that issue is not resolved, we are presented with the most thorough examination of problems associated with the deductive-nomological model of explanation and its variants since the publication of Hempel's Aspects of Scientific Explanation and other Essays in the Philosophy of Science. The discussion begins with Wesley Salmon's monograph-length review of the past forty years of work in the tradition initiated by Hempel and Oppenheim in their groundbreaking article "Studies in the Logic of Explanation". As one of the major players in the debates, Salmon's personal account is informative; it provides a useful introduction to the topic and covers the recent history of work on explanation in a manner that allows the uninitiated to follow the arguments and intricacies of the essays that follow. A main theme in Salmon's essay, as in much of his work, is the relation between the theory of explanation and the concept of causation. Given that the notion of causal laws plays a dominant role in DN explanations, this discussion is most welcome. Causation is also a clear concern of many of the other papers. The resolution of some of the tensions between Salmon's approach to causation, and the various roles of explanation in the philosophy of science, is, in fact, one of the main objectives of the extended concluding piece by Philip Kitcher. For Kitcher, explanations serve as unifying mechanisms for theories within different disciplines. Unification in turn also serves as a criterion for choosing between competing theories. The interplay between, on the one hand, Salmon's attention to the problems deriving from Hempel's initial formulation of DN and, on the other hand, Kitcher's concerns with Salmon's conceptualization of causation, produces one of the more fascinating dialectics of the volume. By attending to their dialogue, we see just how far the theory of explanation has come in the last forty years and yet how slow progress can be when fundamental problems are deeply entrenched. Causation continues to bedevil us. With one exception, the remaining contributors to this volume seem to confirm that judgment. Matti Sintonen, Paul Humphreys, David Papineau, Nancy Cartwright, James Woodward, and Merilee Salmon explore the many facets of causation as it applies to clarifying our explanatory objectives. Peter Railton is an exception. In his paper Railton reminds us that behind the epistemological and pragmatic concerns of most of the other contributors, Wesley Salmon included, there lies a set of metaphysical concerns. A thorough analysis of causation and, hence, a resolution to many of the DN model's problems requires a logically prior assessment of the relation between the epistemology of causation and the metaphysics of necessity. How one decides that issue or cluster of issues, Railton reminds us, will play heavily in the controversies between realists and nonrealists over the proper use of the principle of inference to the best explanation.

Wilfrid Sellars attempts to deflect traditional objections to the straight rule of inductive acceptance by embedding it in a complicated system of levels. This system rests on a theory of probability in which the meaning of "probable" is reconstructed in the context of Sellars' general theory of practical reason. To say a statement is probable means, according to Sellars, that there is good reason for accepting the statement as true. In this paper I examine Sellars' attempt to resuscitate the straight rule and conclude that not only does he fail, but his account of "probable" is circular.

We examine Galileo's theory of evidence as presented in his Dialogue on the Two Chief World Systems. It is argued that for Galileo evidence not only had to be tied to the senses, but, that for purposes of evidential relevance, epistemologically significant experience is only of terrestrial objects and events. This account forms the first part of an argument for understanding Galileo as an instrumentalist. The second part of the argument consists in examining Galileo's views on the limits of knowledge. Given his conviction that we cannot know everything and his requirement that evidence be tied to terrestrial phenomena, claims for instrumentalism seem warranted.

SummaryHempel's Deductive‐Nomological model of explanation is compared to Sellars' brand of essentialism. The source of their differences is shown to lie in their views on the explanatory role of inductively based generalizations. An adequate explanation requires a reasoned account of why an empirical generalization fails. On Sellars' view this entails concentrating on the nature of the things whose behavior is in question. We thereby remove ourselves from the misleading positivist methodology in which one counterinstance renders a generalization uninteresting. It is suggested instead that “disconfirmed” generalizations are of crucial positive methodological importance for purposes of theory development.RésuméLe modèle déductif‐nomologique de Hempel est comparéà l'essentialisme dans la version qu'en propose Sellars. L'auteur montre que leurs différences proviennent de ce qu'ils jugent différemment le rôle explicatif des généralisations inductives et les raisons de l'échec d'une généralisation empirique. D'après Sellars, il faut par conséquent se concentrer sur la nature des choses dont on observe le comportement; on évite ainsi les problèmes méthodologiques soulevés par les théories positivistes standard de la confirmation. L'auteur conclut en montrant que des généralisations infirmées ont une importance positive capitale pour le développement des théories

A volume of essays concerned with mapping out future domains in philosophy of technology, it will serve as an excellent text in a variety of courses. Since the future belongs to the young, in addition to established scholars there are many fresh voices featured. The scope of the essays range from data discrimination to space junk and beyond. This volume offers a glimpse into the future of philosophy of technology, laying out the land in contemporary philosophy technology. The organization maps out the spaces of activity in the field and anticipates the big issues that we will soon face. Exciting new work on social networking, virtual environments, privacy, intellectual property, and discrimination with data constitute crucial avenues of thought for understanding and framing our experiences with and through technology today. Of enduring interest, articles on outer space, engineering design, and technology assessment help anchor this volume in more traditional topics, while work on the relationship between art and technology suggest that some themes that have been less emphasized in recent work will receive new life.

Focused on mapping out contemporary and future domains in philosophy of technology, this volume serves as an excellent, forward-looking resource in the field and in cognate areas of study. The 32 chapters, all of them appearing in print here for the first time, were written by both established scholars and fresh voices. They cover topics ranging from data discrimination and engineering design, to art and technology, space junk, and beyond. Spaces for the Future: A Companion to Philosophy of Technology is structured in six parts: Ethical Space and Experience; Political Space and Agency; Virtual Space and Property; Personal Space and Design; Inner Space and Environment; and Outer Space and Imagination. The organization maps out current and emerging spaces of activity in the field and anticipates the big issues that we soon will face.

In this collection we finally find the philosophy of technology, a young and rapidly developing area of scholarly interest, making contact with history of science and technology, and mainstream epistemological and metaphysical issues. The sophistication of these papers indicates the maturity of the field as it moves away from the advocacy of anti-technology ideological posturing toward a deeper understanding of the options and restraints technological developments provide. The papers presented here take us over a threshold into the real world of complicated social and technological interactions where science and art are shown to be integral to our understanding of technological change, and technological innovations are seen as configuring our knowledge of the world and opening up new possibilities for human development. With its rich historical base, this volume will be of interest to all students concerned about the interactions among technology, society, and philosophy.

The papers presented here derive from the 4th International Confe:--ence on History and Philosophy of Science held in Blacksburg, Virginia, U. S. A., November 2-6, 1982. The Conference was sponsored by the I nternational Union of History and Philosophy of Science and Virginia Polytechnic Institute and State University (Virginia Tech). Particular thanks go to L. Jonathan Cohen, Secretary of the Union, as well as to Dean Henry Bauer of the College of Arts & Sciences, Wilfred Jewkes and the Center for Programs in the Humanities, Arthur Donovan and the Center for the Study of Science in Society and the Department of Philoso­ phy and Religion at Virginia Tech. Not only did they come through with the necessat"y funds, but they were all always ready with a helping hand when things got confusing. Two additional groups of individuals require a special note of thanks. First, considerable appreciation is due the mem­ bers of the Joint Commission of the I nternational Union of History and Philosophy of Science: Maurice Crosland, Risto Hilpinen and Vladimir Kirsanov. They were more than gen­ erous in thei r advice and co-operation. The Local Organizing Committee (Kenneth Alpern, Roger Ariew, Arthur Donovan, Larry Laudan, Ann La Berge, Duncan Porter, Eleonore Stump and Dennis Welch) not only demon­ strated efficiency and insured a pleasant stay for' all participants, but also went out of their way on numerous occasions to make everyone feel at home.
