The ArgumentThe societal context within which science is pursued generally acts as a productive force in the generation of knowledge. To analyze this action it is helpful to consider particular modes of mediation through which societal concerns are projected into the very local and esoteric concerns of a particular domain of research. One such mode of mediation occurs through material systems. Here I treat two such systems – the steam engine and the electric telegraph – in the natural philosophy of (...) William Thomson (Lord Kelvin).The steam engine illustratesconceptualmediation. It simultaneously instantiates “labor value” in political economy and “work” in engineering mechanics, thereby identifying the two concepts in the region of their common reference. The partial identification carries with it a structural analogy between a network of concepts from political economy and a similar network in natural philosophy, providing a potent heuristic for the reformulation and further development of dynamics.The electric telegraph illustratesmethodologicalmediation. It projects the interests of engineering and industry into the interests of electromagnetic theory and vice versa, thereby establishing, in Thomson's view, a Baconian unity of truth and utility. As the common reference of theory and practice, the telegraph locates the truth of theoretical knowledge in its utility and the utility of practical knowledge in its truth.These particular cases of conceptual and methodological mediation indicate how the local practices, concepts, and interests of a research specialty, or subculture, draw on and are adapted to those of the larger culture within which they develop. Thus the analysis of mediation leads to an ecological model of the social construction of scientific knowledge. (shrink)

This paper attempts a critical examination of scholarly understanding of the historical event referred to as "the Darwinian Revolution." In particular, it concentrates on some of the major scholarly works that have appeared since the publication in 1979 of Michael Ruse's "The Darwinian Revolution: Nature Red in Tooth and Claw." The paper closes by arguing that fruitful critical perspectives on what counts as this event can be gained by locating it in a range of historiographic and disciplinary contexts that include (...) the emergence of the discipline of evolutionary biology, the 1959 Darwin centenary, and the maturation of the discipline of the history of science. Broader perspectives on something called the "Darwinian Revolution" are called for that include recognizing that it does not map a one-to-one correspondence with the history of evolution, broadly construed.

Biography as a genre of historiography had been dismissed for some years, criticized for being conservative, resistant to theoretical approaches, and hostile to methodological innovations. But the predominance of a historiography devoted to structures, functions, and statistics has, however, led to a renewed interest in the human factor in history. This paper argues that the pluralism of methods and theories which has emerged thereafter reopened the case for an innovative biography, thus facilitating the convergence of general history and the history (...) of science.
