Der Denkstil der Chemiker. Der Aufsatz diskutiert die Tragfähigkeit des Begriffes “Denkstil”, wie er von Alistair Crombie eingeführt und Ian Hacking aufgegriffen wurde, für das Verständnis dessen, wie das Fach Chemie historisch seine Identität ausgeprägt hat. Obwohl weder Crombie noch Hacking den Begriff “Denkstil” in Bezug auf einzelne Disziplinen verwendet haben, erscheint im Fall der Chemie seine Anwendung besonders vielversprechend, weil er hier hilft, ein zentrales Problem zu thematisieren – nämlich die Frage, wie es Chemikern trotz wechselnder Gegenstandsbereiche und theoretischer (...) Umbrüche gelang, eine eigenständige und stabile Identität auszubilden. Nach einer Einführung in den Begriff “Denkstil”, argumentiert der Aufsatz, dass die Beständigkeit der Chemie als eines Faches wesentlich in ihren Laborpraktiken gründet, die ihrerseits wiederum die spezifische Art der Fragen bestimmten, die Chemiker in ihren Forschungen stellten bzw. die Form der Antworten, nach denen sie suchten. Folgende Merkmale kennzeichnen diesen “chemischen Denkstil” (1) eine spezifische, im Herstellen begründete Form des Wissens, (2) die Befassung mit einzelnen Stoffen und Materialien statt mit Materie im Allgemeinen und (3) eine Beobachtung von Natur besonders im Hinblick auf Transformationsprozesse.The Chemists' Style of Thinking. This paper discusses the relevance of the notion of “styles of scientific thinking” introduced by Alistair Crombie and revisited by Ian Hacking, for understanding how chemistry shaped its identity. Although neither Crombie nor Hacking applied this notion to individual disciplines, it seems appropriate to use it in the case of chemistry because it helps to address a puzzling issue: how did chemists manage to shape an identity of their own, despite shifting territories and theoretical transformations? Following a presentation of the notion of style, I will argue that the stable identity of chemistry is rooted in laboratory practices, which determined the specific questions that chemists put to nature as well as the answers to their questions. The “chemical style of thinking” is characterized by i) a specific way of knowing through making, ii) the concern with individual materials rather than matter in general and iii) a specific commitment to nature.

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

The term philosophy of chemistry is here construed broadly to include some publications from the history of chemistry and chemical education. Of course this initial selection of material has inevitably been biased by the interests of the author. This bibliography supersedes that of van Brakel and Vermeeren (1981), although no attempt has been made to include every single one of their entries, especially in languages other than English. Also, readers interested particularly in articles in German may wish to consult the (...) bibliography by Dittus and Mayer which also contains some material not included here (Dittus and Mayer, 1992). The aim is to maintain an up-to-date version of this bibliography and to publish a revised version in due course. Suggestions for further inclusions should be sent to the author. (shrink)

ABSTRACT This article critically examines the translations of two terms – mineral and mineralogy – in modern China. The last decades of the Qing dynasty witnessed a transition in the terminological usage of the Chinese equivalents of mineral and mineralogy from jinshi and jinshi xue to kuangwu and kuangwu xue. A scrutiny of this transition raises questions regarding not only the exchanges in scientific knowledge between China, the West, and Japan since the nineteenth century, but the changes in the understanding (...) of natural things in China. This article locates the translation of the terms within the scope of cultural translation and the history of science. It sheds new light both on the confrontations between languages and knowledge systems, which led to the re-conceptualization of natural things in China and Japan, and on the interplay between various domestic and transnational forces that shaped the intellectual landscapes in China. Through the confrontations and interplay, mineralogy eventually projected minerals into the domain of science and modern science claimed the authority over understanding these natural things.

James Hutton defended the doctrine of phlogiston in two lengthy dissertations 1792 and 1794. Empirical, biographical and disciplinary contexts jointly explain his position. Observationally, Hutton based his argument on facts about heat, light and the storage of energy, explicitly contrasting them to concerns about weight relationships. Hutton's intellectual development shows how he found these particular problems centrally relevant, and focusing on phlogiston indicates how his better known geology fits into more fundamental thinking about the natural economy. The resonance of Hutton's (...) views with many contemporaries highlights the significance of his views, and suggests how we might reconsider the role of phlogiston in late-eighteenth-century chemistry.

The ‘triumph of the anti-phlogistians’ is a familiar story to the historians and philosophers of science who characterize the Chemical Revolution as a broad conceptual shift. The apparent “incommensurability” of the paradigms across the revolutionary divide has caused much anxiety. Chemists could identify phlogiston and oxygen, however, only with different sets of instrumental practices, theoretical schemes, and philosophical commitments. In addition, the substantive counterpart to phlogiston in the new chemistry was not oxygen, but caloric. By focusing on the changing visions (...) of chemical body across the revolutionary divide with a more sensitive probe into the historical actors’ material manipulations and linguistic usage, we can historicize their laboratory realities and philosophical agenda. An archeology of chemical bodies that configures the fragile stability of the material worlds chemists created in succession promises a philosophical horizon that would recognize our hybrid (natural–artificial) environment as an evolving investigative object of science.

In the course of his chemical investigation of crude platina ore, William Hyde Wollaston in 1802 isolated and characterized the metal palladium. In early 1803, he chose to make known his discovery by offering small samples of the metal for sale through a small shop in London. In the notice advertising the properties of the new metal, no information was given as to its source nor to its discoverer. The unique properties of the metal, and the secrecy surrounding its discovery, (...) led the Irish chemist Richard Chenevix to question the elemental nature of the new metal. His hasty but extensive investigation of the chemical properties of palladium convinced him that it was no more than an alloy of platinum and mercury, and he denounced the discovery as fraudulent. The president of the Royal Society, Joseph Banks, was drawn into the resulting furore, and correspondence between him and Chenevix reveals involved plans to obtain the identity of the palladium discoverer. The controversy is viewed as a significant episode in the continuing debate in the chemical community over the operational definition of a chemical element, and although Chenevix's concern over the growth in the number of new elements was justified, his choice of palladium as a test case was an unfortunate one, for his claim that the metal was an alloy was found to be erroneous. Motives for the actions of both Chenevix and Wollaston are sought, and the judgement that their careers were damaged by the incident is questioned. (shrink)

This paper explores the origins of the analytical definition of simple substance, a concept whose central importance in the new chemistry of Lavoisier and his colleagues is now widely recognized. I argue that this notion derived from the practical activities of metallurgists and mineral assayers, and that the theoretical elaboration necessary for the analytical concept to be understood as relevant to chemistry was inspired by the efforts of enlightened rulers in Sweden and Germany to turn chemical science to the benefit (...) of mining—and thus of the various state treasuries. The involvement of chemically-literate mineralogists in the mining industry led them to adopt the principle that analytically-determined composition was a far more essential aspect of minerals than any mere congeries of properties. The same men who pioneered the analytical notion of simple substance also inaugurated the attempt to define a nomenclature for chemistry based exclusively on composition, as determined in the laboratory. -/- .

How to turn chemistry into an exact science? For chemist Louis-Bernard Guyton de Morveau, the best procedure to achieve this goal was to use resources from theoretical physics as allies in the general delimitation of concepts belonging to that science. Thus, their results could be represented in a rational way and written in mathematical language. His dream was to produce concepts that could translate the dynamics of the material world through this physical chemistry. The key-concept of this dream was that (...) of chemical affinities. In addition to information relevant to understand the meaning of being a Newtonian in the Age of Enlightenment, Guyton de Morveau’s chemical thinking also suggests an alternative understanding of the so-called "chemical revolution".

In Éléments de l'art de la teinture, Claude-Louis Berthollet organized and described knowledge of a chemical craft in terms of contemporary chemical science. The resulting intellectual structure of his treatise established a programme and method for the subsequent improvement of dyeing. Berthollet's descriptive and hierarchical systematization of knowledge rendered problems intelligible and isolated them so that they could be attacked and solved by methodical experimentation. This double-edged processes of solving practical problems, first cognitively and then experimentally, provides a key to (...) understanding the way science has contributed to rapid and systematic technological change.

Scientific progress remains one of the most significant issues in the philosophy of science today. This is not only because of the intrinsic importance of the topic, but also because of its immense difficulty. In what sense exactly does science makes progress, and how is it that scientists are apparently able to achieve it better than people in other realms of human intellectual endeavour? Neither philosophers nor scientists themselves have been able to answer these questions to general satisfaction.

Robin Hendry has recently argued that although the term ‘element’ has traditionally been used in two different senses, there has nonetheless been a continuity of reference. The present article examines this author’s historical and philosophical claims and suggests that he has misdiagnosed the situation in several respects. In particular it is claimed that Hendry’s arguments for the nature of one particular element, oxygen, do not generalize to all elements as he implies. The second main objection is to Hendry’s view that (...) the qua problem can be illuminated by appeal to the intention of scientists.Keywords: Element; Simple substance; Basic substance; Antoine Lavoisier; Dmitri Mendeleev; Reference; Qua problem.

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.

Around fifteen years before the chemical substance alumina could be decomposed in the laboratory, it was identified as a compound and predicted to contain a new element called ‘aluminium’. Using this episode from early nineteenth-century chemistry as a case study for the use of analogical reasoning in science, this paper examines how chemists relied on chemical classifications for the prediction of aluminium. I argue that chemists supplemented direct evidence of chemical decomposition with analogical inferences in order to evaluate the composition (...) of substances. Since they were established on the basis of relevant similarities in chemical properties, classifications were taken to reflect so-called ‘chemical analogies’ between substances. In combination with the knowledge that analogous properties indicated similarities in composition, this enabled chemists to infer the composition of experimentally indecomposable substances by analogy. The trust in such analogical inferences, even if they could not be confirmed through experiment, was justified by pragmatic considerations. Whereas the possibility of decomposing a substance depended on the available laboratory techniques, chemical analogies were thought to last independently of internal composition. It was therefore more practical to keep well-established classes of substances together rather than separate them on the basis of experimental results that might evolve as new techniques were developed. Besides highlighting the links between analogical reasoning and classification, this paper also illustrates the importance of analogy in the evaluation of elementary nature in the early nineteenth century.

Lavoisier defined an element as a chemicalsubstance that cannot be decomposed usingcurrent analytical methods. Mendeleev saw anelement as a substance composed of atoms of thesame atomic weight. These `definitions' doquite different things: Lavoisier'sdistinguishes the elements from the compounds,so that the elements may form the basis of acompositional nomenclature; Mendeleev's offersa criterion of sameness and difference forelemental substances, while Lavoisier's doesnot. In this paper I explore the historical andtheoretical background to each proposal.Lavoisier's and Mendeleev's explicitconceptions of elementhood differed from eachother, and (...) from the official IUPAC definitionof `element' of the 1920s. However, Lavoisierand Mendeleev both subscribed to – andemployed – a deeper notion of a chemicalelement as the component of compound substancesthat (i) can survive chemical change, and (ii)explains the chemical behaviour of itscompounds.

This paper uses scientific perspectivism as a lens for understanding acid experiments from the Chemical Revolution. I argue that this account has several advantages over several recent interpretations of this period, interpretations that do not neatly capture some of the historical experiments on acids. The perspectival view is distinctive in that it avoids discontinuity, allows for the rational resolution of disagreement, and is sensitive to the historical epistemic context.

One of the consequences of the renewed interest in philosophical aspects of chemistry has been the corresponding renewed interest in the periodic system of the elements which embodies so much chemical knowledge in an implicit form.We have therefore decided to further promote scholarship on the periodic system by compiling a bibliography of previously published material. As the title of this article implies, we restrict ourselves to secondary sources. Readers interested in primary material can consult a number of useful references for (...) this purpose. These include the classical treatment on the History of the periodic system by van Spronsen as well as Mazurs’s compilation of over 700 forms of the periodic system. Mazurs also includes a detailed bibliography of articles and books in several different languages. Additional sources of primary articles which come to mind include David Knight’s Classics in the History of Chemistry, Carmen Giunta’s web pages for the history of chemistry and entries under individual scientists in the Dictionary of Scientific Biography. Turning to the present compilation we do not claim this to be a comprehensive list, since it partly reflects the interests of the senior author (E.R.S.), namely the relationship between the periodic system and quantum mechanics. For example, in addition to articles specifically on the periodic system we include a number of articles which deal with the related themes of electronic configurations of the elements. This bias also explains the disproportionate number of references to the work of the senior author.We have tried to include as many as possible of the articles on the periodic system which have appeared in the philosophy of science literature. These include Bensaude, Christie, Hettema and Kuipers, Kultgen, Lipton, Maher, Scerri, Shapere and Sundaram, among others. (shrink)
