Introduction to Dossier Pierre Duhem’s Philosophy and History of Science.

I argue in the paper that classical chemistry is a science predominantly concerned with material substances, both useful materials and pure chemical substances restricted to scientific laboratory studies. The central epistemological and methodological status of material substances corresponds with the material productivity of classical chemistry and its way of producing experimental traces. I further argue that chemist’s ‘pure substances’ have a history, conceptually and materially, and I follow their conceptual history from the Paracelsian concept of purity to the modern concept (...) of pure stoichiometric compounds. The history of the concept of ‘pure substances’ shows that modern chemists’ concept of purity abstracted from usefulness rather than being opposed to it. Thus modern chemists’ interest in pure chemical substances does not presuppose a concept of pure science. (shrink)

An exposition of Pierre Duhem’s formulation of the structure of chemical substances as expressed by their formulas is given, presenting it as a development of his essentially Aristotelian view of mixtures. Duhem’s masterly development of the subject displays an eye for logical clarity familiar from his work in thermodynamics but applied here to the extraction of what he regarded as true from the history of chemistry. Though no longer defensible, the account has a conceptual interest in its own right and (...) illuminates a less frequently discussed side of Duhem’s views. (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)

At first glance twentieth-century philosophy of science seems virtually to ignore chemistry. However this paper argues that a focus on chemistry helped shape the French philosophical reflections about the aims and foundations of scientific methods. Despite patent philosophical disagreements between Duhem, Meyerson, Metzger and Bachelard it is possible to identify the continuity of a tradition that is rooted in their common interest for chemistry. Two distinctive features of the French tradition originated in the attention to what was going on in (...) chemistry.French philosophers of science, in stark contrast with analytic philosophers, considered history of science as the necessary basis for understanding how the human intellect or the scientific spirit tries to grasp the world. This constant reference to historical data was prompted by a fierce controversy about the chemical revolution, which brought the issue of the nature of scientific changes centre stage.A second striking—albeit largely unnoticed—feature of the French tradition is that matter theories are a favourite subject with which to characterize the ways of science. Duhem, Meyerson, Metzger and Bachelard developed most of their views about the methods and aims of science through a discussion of matter theories. Just as the concern with history was prompted by a controversy between chemists, the focus on matter was triggered by a scientific controversy about atomism in the late nineteenth-century.Keywords: France; Epistemology; Chemistry; Revolution; Atomism; Realism.

This article will explore whether there are arguments for Aristotle's concept mixis which can aid our current discussions within the philosophy of chemistry. We remain troubled by the way and extent to which chemical substance in bulk can be identified with or reduced to the stability and structure of molecules, and whether these in turn can be identified with or reduced to elemental atoms and the quantum theoretical characterization of their electrons. Aristotle was as determined as we are to think (...) through the implications of substances comprised of constituents and to question their status in chemical compounds. (shrink)
