This article presents a reconstruction of the so-called classical, formal or Mendelian genetics, which is intended to be more complete and adequate than existing reconstructions. This reconstruction has been carried out with the instruments, duly modified and extended with respect to the case under consideration, of the structuralist conception of theories. The so-called Mendel’s Laws, as well as linkage genetics and gene mapping are formulated in a precise manner while the global structure of genetics is represented as a theory-net. These (...) results are of methodological, philosophical and didactical relevance. (shrink)

The aim of this paper is to characterize the various structuralist reduction concepts as structure-preserving maps in a succinct and unifying way. To begin with, some important intuitive adequacy conditions are discussed that a good (structuralist) reduction concept should satisfy. Having reconstructed these intuitive conditions in the structuralist framework, it turns out that they divide into two mutually incompatible sets of requirements. Accordingly there exist (at least) two essentially different types of structuralist reduction concepts: the first type stresses the existence (...) of a deductive or inferential link between the reducing and the reduced theory; the second type emphasizes the greater explanatory power the reducing theory should have in comparison with the reduced theory. The problem of the incompatibility of equally plausible reduction concepts is treated in the last section and a proposal is made for its solution consisting in the definition of a multiple synthetizing reduction relation.

This essay is an attempt to consider dynamic aspects of scientific theorising from a formal perspective. Our emphasis will be on the aims and methods for constructing formal models of theory dynamics which will be conceived from a general or 'theoretical' rather than 'applied' standpoint.

Though formal metascience has made rapid advances over the past few decades, it has seldom been seen to contribute much to the rational reconstruction of scientic development; for the most part, logical concepts have found application in the synchronic analysis of scientic theories. It should be important, therefore, to consider to what extent diachronic or dynamic aspects of scientic theorizing may also be captured within the connes of a formal metascientic framework, and what tools are best suited for constructing a (...) general model of theory dynamics.

In this paper, the potentials of systematically linking philosophy of science with bibliometrics are investigated by exploring whether concepts developed within the structuralist theory of science can be used as interpretative basis for author co-citation studies. It is argued that clusters of co-cited authors cannot be interpreted straightforwardly as scientific communities nor as scientific generations. The first reason is that the respective constituents differ (authors vs. scientists), the second is that the co-citation relation generates non-Kuhnian communities, i.e. communities not sharing (...) a paradigm/theory-core. Instead, co-citation clusters can more adequately be taken to represent communities of common (epistemic) interest. Hence, the concepts of interest community and of discourse community are introduced into the structuralist framework making use of the notion of intended application. All in all, it becomes clear that a full-fledged theory of publication is the still missing prerequisite for further linking bibliometrics and philosophy of science at a large scale. (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.

In this paper I propose to examine, and in part revive, a time-honoured perspective to inquiry in general and scientific explanation in particular. The perspective is to view inquiry as a search for answers to questions. If there is anything that deserves to be called a working scientist's view of his or her daily work, it surely is that he or she phrases questions and attempts to find satisfactory answers to them.
