Dans cet article, on suggère qu’un rôle central peut être assigné à la philosophie de la chimie dans la philosophie des sciences post-kuhnienne en général, et dans l’analyse du débat opposant le réalisme scientifique à l’anti-réalisme dans la philosophie des sciences standard. La philosophie des sciences construit la science comme une pratique plus que comme un réseau d’assertions. On soutient que le réalisme pratique permet d’éviter les défauts à la fois du réalisme scientifique standard et de l’anti-réalisme. On analyse un (...) livre important publié récemment, B. Bensaude-Vincent’s & J. Simon’s Chemistry — The Impure Science [Bensaude-Vincent & Simon 2008], et on interprète la position des auteurs comme une sorte de réalisme pratique. (shrink)

The focus of the paper is on Rein Vihalemm’s novel approach to science called practical realism. From the perspective of Vihalemm, science is not only theoretical but first and foremost a practical activity. This kind of approach puts chemistry rather than physics into the position of a typical science as chemistry has a dual character resting on both constructive-hypothetico-deductive and classifying-historico-descriptive types of cognition. Chemists deal with finding out the laws of nature like the physicists. However, in addition to this (...) they deal with substances or stuff that is rather an activity typical to natural history. The analysis of the dual character of chemistry brings about the need to analyse philosophically the reasons why physics has held the position of the only science proper so far. The comparative analysis of physics and chemistry at the basis of practical realism suggests that it is chemistry rather than physics that should hold a special position among sciences. Perhaps we should exchange ϕ-science for χ-science. (shrink)

The paper deals with the philosophy of science and technology from a new perspective. The analysis connects closely to the novel approach to scientific research called practical realism of the late Estonian philosopher of science and chemistry Rein Vihalemm. From his perspective, science is not only theoretical but even more clearly a practical activity. This kind of practice-based approach puts chemistry rather than physics into the position of the most typical science as chemistry has a dual character resting on both (...) constructive-hypothetico-deductive and classifying-historico-descriptive types of cognition. Chemists deal with finding out the laws of nature just like the physicists do. However, in addition to this chemistry deals with substances or stuff that is rather an activity typical to natural history. The analysis of the dual character of chemistry brings forward the need to analyse philosophically also the reasons why physics has held the position of the model science so far. The problem unfolds in the context of practical realism. However, some earlier observations concerning the dual character of chemistry influenced us as well, i.e. by Friedrich Paneth, Michael Polanyi and Edward Caldin. More recently, Bernadette Bensaude-Vincent and Jonathan Simon have given their own explanation of why and how chemistry has a dual character. From their perspective, chemistry is a perfect technical science as it aims at applications, literally at producing something new. Bensaude-Vincent and Simon call their approach operational realism. The latter, however, does not differ from practical realism. (shrink)

This paper discusses the proposal made by Lombardi and Labarca (Found Chem 7:125–148, 2005) that internal realism can secure the ontological autonomy of chemistry. I argue that internal realism is not, by itself, sufficient to accomplish this task. The fact that conceptual schemes may differ with respect to their theoretical virtues, and the possibility that the relations between them may be reductive undermine the premise that each conceptual scheme has an equal right to define its own ontology, which is a (...) key premise in Lombardi and Labarca’s proposal.

All suggested notions of reduction of two scientific theories are critically reviewed and analyzed. In particular those applied to the case of the alleged reduction of Chemistry to Quantum mechanics are examined. Since it is recognized that the weakness of this field of research is the lack of a definition of a scientific theory, it is suggested that a scientific theory is characterized by two choices regarding two dichotomies, that is, the kind of mathematics and the kind of logic. According (...) to this view a reduction is only possible between two theories in which the same choices are shared. As a consequence, only one case of reduction in the history of physics is recognized: physical optics to electromagnetism, a case that is commonly accepted. The other cases of claimed reductions are recognized as impossible, owing to the different choices of the two theories at issue and hence the radical variations in meaning of their shared basic notions. In particular, the claimed reduction of Chemistry to Quantum mechanics is disproved in detail. (shrink)
