We revive the idea that a deductive-nomological explanation of a scientific theory by its successor may be defensible, even in those common and troublesome cases where the theories concerned are mutually incompatible; and limiting, approximating and counterfactual assumptions may be required in order to define a logical relation between them. Our solution is based on a general characterization of limiting relations between physical theories using the method of nonstandard analysis.

In the present paper Cohen's and Lee's theory of social conformity and Festinger's theory of cognitive dissonance are first reconstructed according to a revised form of the so-called “structuralist theory-conception” developed by Sneed and Stegmüller with their collaborators. Then the two theories are conceptually correlated in the sense of a technical notion of conceptual correlation which can be shown to be an essential generalization of the theory-relations handled by the structuralist. It will turn out that there is no unique way (...) to connect these theories with each other. However, it is shown that two ontologically and conceptually different theories can be correlated. This in turn gives in principle an opportunity to compare critically these two theories given that the constructed conceptual correlation is sufficiently sound and that the theories are empirically testable to a sufficient extent.

The project of integrated HPS has occupied philosophers of science in one form or another since at least the 1960s. Yet, despite this substantial interest in bringing together philosophical and historical reflections on the nature of science, history of science and formal philosophy of science remain as divided as ever. In this paper, I will argue that the continuing separation between historical and formal philosophy of science is ill-founded. I will argue for this in both abstract and concrete terms. At (...) the abstract level, I reconstruct two possible arguments for the incompatibility of historical and formal philosophy of science and argue that they are both wanting. At the concrete level, I discuss how historical and formal philosophy of science have been brought together in practice, namely: in the form of a largely forgotten research tradition that I will refer to here as the study of formalized macro-units. After a brief exposition, I argue that this research tradition has been unduly overlooked by historically minded philosophers of science. Bringing together these observations, I argue that the divide between historical and formal philosophy of science is not grounded in any substantive arguments, but can be primarily attributed to disciplinary happenstance.

In his 1982 Presidential Address to the PSA Ernan McMullin proposed that the Kuhnian “revolution” in the philosophy of science amounts, in part, to the growing awareness that theory-appraisal is to be modelled on decisions and value judgments rather than rule-governed inferences (McMullin 1983). This viewpoint has its attractions but needs developing before it can satisfy skeptics, such as Larry Laudan. For Laudan complains that Kuhn has provided no general model to back up his value-geared account, and that the view (...) leads to untenable subjectivism which Kuhn has tried to avoid.I shall try to show that neither complaint stands to criticism, by joining two ideas. The first – that of modelling theory decisions along decision theory – is not a novel one, but even its supporters have failed to see that it makes Kuhn’s subjectivity a live but respectable possibility.

Unter dem Begriff der „Verwissenschaftlichung der Methodologie der Wissenschaft“ verstehen wir den Einfluß wissenschaftlicher Erkenntnis auf die eine oder andere Art und Weise auf die Methodologie der Wissenschaft, insbesondere den Gebrauch von wissenschaftlichen Ideen und Methoden für die Formulierung und Lösung von methodologischen Problemen der Wissenschaft und Problemen der Methodologie selbst. Es werden vier Haupttendenzen im Prozeß der Verwissenschaftlichung der Methodologie vorgestellt: (a) der Übergang vom „statement view“ zum mathematischen Holismus; (b) die Verwissenschaftlichung auf system-theoretischer Basis; (c) der Einzug soziologischer (...) Methoden in die methodologische Analyse der Wissenschaft und (d) die methodologischen Anwendungen von Forschungsresultaten im Bereich der Künstlichen Intelligenz. Darüberhinaus werden einige besondere Formen der Implementierung wissenschaftlicher Konstruktionen in der Methodologie ins Auge gefaßt. (shrink)

La parution de la monographic de Sneed,The Logical Structure of Mathematical Physics a suscité un renouveau d'intérêt en philosophie contemporaine des sciences. Cet ouvrage arrivait à un moment où l'épistémologie des sciences, telle que développée dans les milieux germaniques et anglo-saxons, accusait de graves insuffisances dans la reconstruction rationnelle du développement historique des théories physiques. Mis sur la défensive par les thèses et arguments historiques de Kuhn et de Feyerabend, ces milieux « orthodoxes » devaient reconnaitre l'état embryonnaire de ce (...) qui devait être uneépistémologie diachroniquedes sciences, une épistémologie du changement scientifique où les méthodes d'analyse formelle puissent être aussi mises á contribution. A cela s'ajoutait un certain malaise, une certaine stagnation de la problématique, plus synchronique, de l'approche traditionnelle issue du mouvement empiriste logique. Le probleme de la dichotomielangage théorique—langage observationnel, ainsi que son fidèle compagnon, le problème destermes théoriques, le statut épistémologique desrègies de correspondance, la dèfinition du concept d'analyticitéen science, autant de questions qui avaient été discutées et critiquées, à maintes reprises, pour aboutir à des résultats peu concluants aux yeux des philosophes, comme à ceux des physiciens préoccupés des fondements de leur discipline et à qui la teneur de cette discussion semblait souvent étrangère à la pratique scientifique.
