This collection of 17 articles papers offers an overview of the philosophical activities of a group of philosophers (who have been) working at Groningen University. The meta- methodological assumption that unifies the research of this group holds that there is a way of doing philosophy of science that constitutes a middle course between abstract normative philosophy of science and descriptive social studies of science. On the one hand, it is argued with social studies of science that philosophy should take notice of what scientists actually do. On the other hand, however, it is claimed that philosophy can and should aim to reveal cognitive patterns in the processes and products of scientific and common sense knowledge. Since it is thought that those patterns can function as guidelines in new research and/or in research in other disciplines, philosophy can nevertheless hold on to the normative aim which is characteristic of “classical” philosophy of science.

Although the papers gathered in this volume are centered around this common methodological assumption, they cover a diversity of subjects. Some papers deal with general problems of science, knowledge, cognition and argumentation, others with topics relating to foundational problems of particular sciences. Therefore this volume is of interest to philosophers of science, to philosophers of knowledge and argumentation in general, to philosophers of mind, as well as to scientists working in the physical and applied sciences, biology, psychology and economy who are interested in the foundations of their disciplines.

After a foreword by Leszek Nowak and a general introduction by the editors follow the four parts of the book each preceded by a special introduction:

Part I: Conceptual analysis in service of various research programmes (Henk Zandvoort, Rein Vos, Rick Looijen, Gerben Stavenga, Rene Dalitz)

Part II: The logic of the evaluation of arguments, hypotheses, default rules, and interesting theorems (Erik Krabbe, Theo Kuipers, Alfons Keupink, Maarten Janssen, Yao-Hua Tan, Ber Hamminga)

Part III: Three challenges to the truth approximation programme (Sjoerd Zwart, Hinne Hettema, Theo Kuipers, Roberto Festa)

Part IV: Explicating psychological intuitions (Anne-Ruth Mackor, Jeanne Peijnenburg, Lex Guichard, Michel ter Hark).

The Groningen research group was recently qualified, by an official international assessment committee, as one of the best philosophy research groups in the Netherlands.
