The ArgumentThis paper charts eighteenth-century chemistry's transition from its definition as an art to its proclaimed status as a science. Both the general concept of art and specific practices of eighteenth-century chemists are explored to account for this transition. As a disciplined activity, art orients practitioners' attention toward particular directions and away from others, providing a structured space of possibilities within which their discipline develops. Consequently, while chemists throughout the eighteenth century aspired to reveal nature's “true voice,” the path of (...) their investigations was directed by and toward their laboratory manipulations. So long as the chemical community maintained an ethos of polite cooperation and eschewed theoretical wrangling, this point was hidden by a rhetoric of “matter of fact” reporting. But as “facts” mounted in the 1770s and 1780s, especially in pneumatic chemistry, cooperation gave way to contention as chemists sought to name and organize their findings without the guidance of a communally accepted “natural” system. Lavoisier and his fellow “new” chemists offered a forceful solution to this dilemma by introducing a revolutionary network of theories, nomenclature, and instruments that unabashedly fused the productive manipulation of their laboratory work with what they claimed as the structure and activity of nature.

The ArgumentThis paper is a study of the role of language in scientific activity. It recommends that language be viewed as a community's means of patterning its affairs. Language represents where the boundaries of the community are and who is entitled to speak within it, and it displays the structures of authority in the community. Moreover, language precipitates the community's view of what the world is like, such that linguistic usages can be taken as referring to that world. Thus, language (...) connects on the one side to a community's practical life, and, on the other, to the reality on which it “reports.”The example treated is Robert Boyle's view of the language proper for experimental practice, and his arguments against the value and legitimacy of mathematical representations within the experimental community. Boyle argued that the use of mathematics was inappropriate because (i) it would restrict the number of potential participants; (ii) it would give rise to unwarranted expectations of the certainty and accuracy to be expected of real physical inquiries; (iii) it would suggest views of natural law and God's relations with the natural world which were incorrect and possibly dangerous; and because (iv) the world upon which the experimentalist operated was not such as was represented by mathematical idealizations. I try to establish that decision about the appropriate language for the experimental community was a moral choice. (shrink)

Outline of the historiographic discussion on 18th-century linguistic theories.

Implicit in the theoretical chemical writings of Antoine Laurent Lavoisier is a theory of language that is not in complete harmony with the philosopher of language whom he takes as his explicit authority, Condillac. Lavoisier's reform of the nomenclature of chemistry leads to his dividing scientific language into two sets with different properties: a denotative artificial nomenclature and connotative natural language. This division supposedly permits knowledge to be stored in the nomenclature while the natural language retains the rhetorical tools necessary (...) for creative thought and argument. The consequences of this reform of scientific language are, however, the opposite of what Lavoisier had intended. (shrink)

Using the concept of purity to reflect on the relationship between chemical practice and the philosophy of science, this article considers the philosophical significance of the chemical manipulations that aim to purify or otherwise transform matter. Starting from a consideration of the nature and role of pure (or idealised) examples in philosophy of science, the article underlines the temptation towards abstraction and theory for both scientists and philosophers. The article goes on to argue that chemistry, despite its increasing theoretical sophistication, (...) is a science that remains particularly close to laboratory manipulations. This point is made in reference to the work of Gaston Bachelard on the production of purity and with the aid of historical examples, notably exploring the interplay between techniques of purification and the definition of elements, with special attention paid to Lavoisier’s definition of elements as the final limit of analysis. The closing section concerns the manufacture of steel from iron ore in the eighteenth century, illustrating this process using texts by Pierre-Joseph Macquer and Denis Diderot. Steel production is used to illustrate the kinds of philosophical question that are raised by paying attention to the details of chemical practice rather than jumping straight to chemical theory and also suggests how scientific theory can emerge from this practice itself.

This paper examines the negative response to Dalton’s atomic symbols by situating them in the context of the normative eighteenth-century representational system of affinity tables. Aesthetic analysis of the affinity tables reveals them as schema embedded with a potent functionalist empiricism. In contrast, the aesthetics of Dalton's symbols is associated with hypothetico-deductivism and alchemical iconicism.

In recent years the Chemical Revolution has become a renewed focus of interest among historians of science. This interest isshaped by interpretive strategies associated with the emergence anddevelopment of the discipline of the history of science. The disciplineoccupies a contested intellectual terrain formed in part by thedevelopment and cultural entanglements of science itself. Threestages in this development are analyzed in this paper. Theinterpretive strategies that characterized each stage are elucidatedand traced to the disciplinary interests that gave rise to them. Whilepositivists (...) and whigs appropriated the history of science to thejustificatory and celebratory needs of science itself, postpositivistslinked it to philosophical models of rationality, and sociologists ofknowledge sought its sociological reconstruction. Since none of thesestrategies do justice to the complexity of historical events, a modelof the Chemical Revolution is outlined which upholds the autonomyand specificity of history and the methods used to study it.
