Part I presents a quantitative-empirical outline of chemistry, esp. preparative chemistry, concerning its dominant role in today's science, its dynamics, and its methods and aims. Emphasis is laid on the poietical character of chemistry for which a methodological model is derived. Part II discusses standard distinction between science and technology, from Aristotle (whose theses are reconsidered in the light of modern sciences) to modern philosophy of technology. Against the background of results of Part I, it is argued that all these (...) distinctions fail, because the underlying concepts of science are either out-dated, one-sided, or arbitrary. A deeper understanding of today's sciences requires, in particular, a philosopical investigation of chemistry. (shrink)

In this paper I present a historiography of the recent emergence of philosophy of chemistry. Special attention is given to the interest in this domain in Eastern Europe before the collapse of the USSR. It is shown that the initial neglect of the philosophy of chemistry is due to the unanimous view in philosophy and philosophy of science that only physics is a proper science (to put in Kant's words). More recently, due to the common though incorrect assumption that chemistry (...) can in principle be reduced to physics, the neglect continued, even when interest in sciences such as biology and psychology entered more strongly in philosophy of science. It is concluded that chemistry is an autonomous science and is perhaps a more typical science than physics. (shrink)

The historical development of the electronic configuration model is traced and the status of the model with respect to quantum mechanics is examined. The successes and problems raised by the model are explored, particularly in chemical ab initio calculations. The relevance of these issues to whether chemistry has been reduced to quantum mechanics is discussed, as are some general notions on reduction.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

Philosophie ist konkret und abstrakt. Sie ist konkret im Gespür für Probleme, die jeden – oder jeden in einem bestimmten Bereich – betreffen. Sie ist abstrakt in der kritischen Formulierung und Lösung von Problemen, indem sie von besonderen Bedingungen und Voreingenommenheiten abstrahiert. Philosophie erfordert Kreativität, Phantasie und die Bereitschaft zu Unkonventionellem in der Wahl der Problemzugangsweisen. Wie alle Wissenschaften ist sie als Methode lehr- und entwickelbar, sofern ein gewisses Talent vorhanden ist. Philosophie beginnt dort, wo Wissenschaftler nicht mehr weiter fragen. (...) Was heute Philosophie ist, kann morgen Wissenschaft sein – Naturwissenschaft, Sozialwissenschaft oder Geisteswissenschaft –, Philosophie hat keine Vorlieben. (shrink)

While in the research area known,as ’philosophy of science' there is a growing interest in separate disciplines of the empirical sciences, applied sciences and even technologies, one can find hardly any reference to the discipline of chemistry other than some preliminary discussions of chemical concepts or studies concerning the rational reconstruction of the history of chemistry. No analyses, which might be called 'philosophy of chemistry’ can be found to date. It is hoped that this review paper on what has been (...) published on the philosophy of chemistry will show that chemistry is a philosophically rich field. After an introduction, in section 2, a more detailed classification is given of the various areas from which a (marginal) interest in the philosophy of chemistry has emerged.In section 3 there is a review of the opinions on the subject matter of chemistry, be it straightforward definition or indications of the relation to other natural sciences, in particular physics. In section 4 publications on the philosophy of chemistry are reviewed which fit the conventional format of the philosophy of science (discussing laws, theories,explanations, models). In section 5 some of the literature on the concept of chemical species is reviewed. In section 6 and 7 a review of the literature on the concepts of chemical structure and chemical reactions is presented. (shrink)

The birth of a new discipline, called 'physical chemistry', is sometimes related to the names OSTWALD, ARRHENIUS and VAN'T HOFF and dated back to the year 1887, when OSTWALD founded the Zeitschrift für physikalische Chemie.[1] But as many historians have pointed out, the phrase 'physical chemistry' was widely used before that and the topics under investigation partially go back to Robert BOYLE's attempts to connect chemistry with concepts of mechanical philosophy.[2] The idea of a sudden birth of physical chemistry in (...) 1887 seems to be a founder myth.[3] But there is no doubt that in the late nineteenth-century there was a rapid growth of research in fields now understood as physical chemistry: chemical thermodynamics, electrochemistry, photochemistry, spectroscopy, chemical kinetics etc. (shrink)

Eine philosophische Auseinandersetzung mit der Chemie ist so neu,1 daß die meisten Philosophen gegenwärtig Schwierigkeiten haben dürften, überhaupt eine thematische Verbindung zwischen beiden Fächern herstellen zu können, was auf ähnliche Weise übrigens auch auf Chemiker zutrifft. Daß dies nicht immer so war, wird sofort einsichtig, wenn man bedenkt, daß die chemische Frage nach der substantiellen Verschiedenartigkeit von Stoffen und ihren gegenseitigen Umwandlungsmöglichkeiten bereits zu den Grundfragen aller antiken Naturphilosophen gehörte. Es dürfte insbesondere dem theoretischen Ungenügen des Konzepts stofflicher Qualitäten nach (...) über 2000 Jahren zuzuschreiben sein, daß sich die neuzeitliche mechanische (Natur-)Philosophie gegen Ende des 17. Jahrhundert in nahezu konkurrenzloser Weise durchzusetzen vermochte, so daß jeder, der sich aufs moderne Philosophieren verstehen wollte, der Doktrin der primären (mechanischen) Qualitäten einschließlich der Reduktion jeder Veränderung auf Ortsveränderung anhängen mußte.2 Dieser Ansatz versprach auf einer theoretischen Ebene, mit einem Schlage alle Möglichkeiten stofflich substantieller Verschiedenheit und Veränderung in einen überschaubaren quantitativen Rahmen einzufangen. Diese Abwendung der Philosophie von den ursprünglichen chemischen Fragen beinhaltet drei für den vorliegenden Zusammenhang wichtige Kategorienverschiebungen. (1) Die Kategorie der substantiellen Verschiedenheit verliert ihre Bedeutung in bezug auf Stoffe.. (shrink)

Summary Opinion is divided as to whether chemistry is reducible to physics. The problem can be given a satisfactory solution provided three conditions are met: that a science not be identified with its theories; that several notions of theory dependence be distinguished; and that quantum chemistry, rather than classical chemistry, be compared with physics. This paper proposes to perform all three tasks. It does so by analyzing the methodological concepts concerned as well as by examining the way a chemical rate (...) constant is derivable with the help of the quantum atomic theory. The conclusion is that chemistry, and in particular quantum chemistry, is not a part of physics although it is certainly based on the latter. (shrink)

Chemical structures are among the trademarks of our profession, as surely chemical as flasks, beakers and distillation columns. When someone sees one of us busily scribbling formulas or structures, he or she has no trouble identifying a chemist. Yet these familiar objects, which accompany our work from start to end, from the initial doodlings (Fig. I) to the final polished artwork in a publication (Fig. II), are deceptively simple. They raise interesting and difficult questions about representation. It is the intent (...) of this article to reflect upon molecular graphics. (shrink)

Protochemistry. The Program of a Methodical Foundation of Chemistry. "Protochemistry" - in analogy to protophysics - is sketched as the program of a methodical foundation of chemistry. "Foundation" means to reconstruct the methods (both linguistic and poietic) which lead from the prescientific every-day-practice of mastering properties of substances to scientific theories of modern chemistry. Four types of chemical terms are distinguished, depending on different methods of definition and different areas of reference. Consequences of the program if realized are pointed out.
