An important fact about human labor is that it can result not just in reproduction of what it started with, but in something new, a surplus product. When the latter is a means of production, it makes possible a mechanism of change consisting of reproduction by means of the expanded means of production. Each iteration of the labor process can differ from the preceding one insofar as it incorporates the surplus generated previously. Over the long-term, this cyclical process can lead (...) to the self-transformation of labor and, through it, of human societies and cultures. In this paper, I argue that this mechanism of change is also at work in the history of science. I argue that the form this mechanism takes in science is that of a feedback loop between discovery and instrument construction. This process requires the integration, and transformation into material form, of different kinds of knowledge. Based on this mechanism, I defend a concept of scientific progress as transcendence of the limitations of native human epistemic abilities. I also criticize narrowly biologistic approaches to the history of science for ignoring the role of surplus generation in transforming the labor process, and discuss some problems associated with viewing science as labor.

resumo: Neste artigo propomos abordar a relação entre os conceitos de natureza e de artefato a partir de uma racionalidade química e alquímica. Pretendemos mostrar que essa racionalidade é originariamente tecnocientífica e apontar o modo como alquimistas e químicos construíram um quadro conceitual ancorado no laboratório do químico e no laboratório do orgânico. Nosso propósito é explicitar as transgressões e a capilaridade tecnocultural dos materiais criados nos laboratórios, bem como da existência de um estilo químico de raciocinar com suas particularidades (...) ontológicas, epistemológicas e metodológicas. abstract: In this article we propose to treat the relation between the concepts of nature and artifact from a chemical and alchemical rationality. We intend to show that this rationality is originally technoscientific and to point out the way alchemists and chemists built a conceptual board anchored in the laboratory of the chemical and in the laboratory of the organic. Our proposal is to explain the transgressions and technocultural capillarity of the materials created in the laboratories, as well as the existence of a chemical style of reasoning with its ontological, epistemological and methodological particularities.

RESUMO Neste artigo pretendo identificar um "estilo de raciocínio" próprio à química e apontar a disseminação de seus produtos e conceitos. O objetivo é o de explicitar alguns elementos que caracterizam o estilo de pensar e de fazer da química na segunda metade do século XVIII, sua capilarização técnico-cultural. O delineamento de um estilo químico de raciocinar origina-se da constância dos espaços técnico-epistêmicos em que o saber químico é construído. A química é uma ciência de laboratório, eminentemente técnica e operatória, (...) quer dizer, trata-se de um conhecimento técnico-científico stricto sensu. Produtora de artefatos, a ciência química é inseparável da técnica, da tecnologia e da indústria, de maneira que sua identidade epistêmica é indissociável de sua história. Seu estilo caracteriza um valor profundo na cultura técnica do homo faber, do poder de agir sobre a natureza e de transformá-la através de manipulações e de rearranjos. ABSTRACT In this paper I will identify a "style of reasoning" that is proper to to Chemistry and to point to the dissemination of its products and concepts. My aim is to explain some elements that characterize the style of thinking and engaging in Chemistry in the second half of the 18th century, its techno-cultural capillary action. The shaping of a chemical style of reasoning originated from the constancy of the techno-epistemic sites in which chemical knowledge is formed. Chemistry is a laboratory science, eminently technical and operative, i.e., it deals with a techno-scientific knowledge stricto sensu. A producer of artifacts, chemical science is inseparable from technique, technology and industry, in such a way that its epistemic identity is inseparable from its history. Its style marks a profound value in the technical culture of the homo faber, the power of acting upon nature and transforming it through manipulations and rearrangements. (shrink)

I argue and demonstrate in this essay that interconnected systems of science and technology, or technoscience, existed long before the late nineteenth century, and that eighteenth-century chemistry was such an early form of technoscience. Based on recent historical research on the early development of carbon chemistry from the late 1820s until the 1840s—which revealed that early carbon chemistry was an experimental expert culture that was largely detached from the mundane industrial world—I further examine the question of the internal preconditions within (...) the expert culture of carbon chemistry that contributed to its convergence with the synthetic-dye industry in the late 1850s. I argue that the introduction of new types and techniques of organic-chemical reactions and organic substances in this experimental expert culture, along with the application of chemical formulae as paper tools for modeling reactions as well as the chemical constitution and structure of substances, enabled academic chemists to make specific, novel contributions to chemical technology and industry in the second half of the nineteenth century.

In scientific work, sonification is primarily thought of as a novel way to communicate post hoc research findings to lay audiences but only rarely, if ever, as a component of the research itself. This article argues that, rather than any inherent epistemological limitations of sound as a medium of scientific reasoning, this framing reflects a sociohistorical tendency to “silence” experimental techniques as they become widely adopted—both in terms of the literal silencing of noisy instrumentation and the elision of the role (...) of sound in received discovery accounts. This tendency is well-illustrated by the history of electrophysiology research, particularly the case of the electrical penetration graph, an instrument used by entomologists to study how insects feed on plants. Combining participant observation, interviews, and analysis of EPG technical literature, this article recovers the unacknowledged role of sound in EPG’s exploratory stages and gradual emergence as a standard laboratory technique as well as its gradual silencing as a consequence of this standardizing process.
