Often, regret implies the wish not to have performed certain actions. In this article I claim that this wish can to some extent be fulfilled: it is possible, in a sense, to influence the character of actions that have already been performed. This possibility arises from combining a first person perspective with an outlook on actions as expressions of tendencies, where tendencies are identified on the basis of a number of actions. The idea is specified within the framework of Carnapian reduction sentences, but this technique is in no sense mandatory: it can be formulated in other vocabularies as well

In The Structure of Science, Ernest Nagel finds fault with Werner Heisenberg’s explication of the uncertainty principle. Nagel’s complaint is that this principle does not follow from the impossibility of measuring with precision both the position and the momentum of a particle, as Heisenberg intimates, rather it is the other way around. Recent developments in theoretical physics have shown that Nagel’s argument is more substantial than he could have envisaged. In particular it has become clear that there are in fact two uncertainty principles; as a result, there are four pairs of quantities to examine, whereas Heisenberg considers only one. These findings throw new light on Nagel’s criticism. They enable us to see that his intuition was surprisingly apposite, but also make clear where his argument misses the mark.

This book is the first of two volumes devoted to the work of Theo Kuipers, a leading Dutch philosopher of science. Philosophers and scientists from all over the world, thirty seven in all, comment on Kuipers' philosophy, and each of their commentaries is followed by a reply from Kuipers. The present volume focuses on Kuipers' views on confirmation, empirical progress, and truth approximation, as laid down in his From Instrumentalism to Constructive Realism (Kluwer, 2000). In this book, Kuipers offered a synthesis of Carnap's and Hempel's confirmation theory on the one hand, and Popper's theory of truth approximation on the other. The key element of this synthesis is a sophisticated methodology, which enables the evaluation of theories in terms of their problems and successes (even if the theories are already falsified), and which also fits well with the claim that one theory is closer to the truth than another. Ilkka Niiniluoto, Patrick Maher, John Welch, Gerhard Schurz, Igor Douven, Bert Hamminga, David Miller, Johan van Benthem, Sjoerd Zwart, Thomas Mormann, Jesús Zamora Bonilla, Isabella Burger & Johannes Heidema, Joke Meheus, Hans Mooij, and Diderik Batens comment on these ideas of Kuipers, and many present their own account. The present book also contains a synopsis of From Instrumentalism to Constructive Realism. It can be read independently of the second volume of Essays in Debate with Theo Kuipers, which is devoted to Kuipers' Structures in Science (2001).

Kuipers' model of action explanation is compared, first with that of Anscombe, and then with models in the post-Anscombian tradition. Whereas Kuipers and Anscombe differ on the question of the first-person view, the difference with post-Anscombian writers concerns the so-called intentional statement. Kuipers criticizes the models of both Hempel and von Wright for their lack of an intentional statement. Kuipers' own model seems immune to this criticism, since it contains no less than two intentional statements, a "specific" and an "unspecific" one. I argue that, contrary to appearances, it is not so immune. The call for intentional statements is in fact a call for intentions that are irreducible to beliefs and desires. Kuipers' intentional statements, however, are about intentions that can be so reduced.

This book is the second of two volumes devoted to the work of Theo Kuipers, a leading Dutch philosopher of science. Philosophers and scientists from all over the world, thirty seven in all, comment on Kuipers’ philosophy, and each of their commentaries is followed by a reply from Kuipers. The present volume is devoted to Kuipers’ neo-classical philosophy of science, as laid down in his Structures in Science . Kuipers defends a dialectical interaction between science and philosophy in that he views philosophy of science as a meta-science which formulates cognitive structures that provide heuristic patterns for actual scientific research, including design research. In addition, Kuipers pays considerable attention to the computational approaches to philosophy of science as well as to the ethics of doing research. Thomas Nickles, David Atkinson, Jean-Paul van Bendegem, Maarten Franssen, Anne Ruth Mackor, Arno Wouters, Erik Weber & Helena de Preester, Eric Scerri, Adam Grobler & Andrzej Wisniewski, Alexander van den Bosch, Gerard Vreeswijk, Jaap Kamps, Paul Thagard, Emma Ruttkamp, Robert Causey, Henk Zandvoort comment on these ideas of Kuipers, and many present their own account. The present book also contains a synopsis of Structures in Science. It can be read independently of the first volume of Essays in Debate with Theo Kuipers, which is devoted to Kuipers’ From Instrumentalism to Constructive Realism
