Ludwik Fleck is a pioneer of the contemporary social constructionist trend in scientific theory, where his central concept of thinking style has become standard fare. Yet the concept is too often misunderstood and simplified with serious consequences not only for Fleck studies. My essay situates Fleck’s concept of thinking style in the historical context of the 1920s and ‘30s, when the notion of style was first applied to the natural sciences, in order to illustrate the uniqueness of Fleck’s concept among (...) the uses of style by his contemporaries and, finally, to examine the epistemological, methodological, and political consequences of this distinction.

Selectionist evolutionary theory has often been faulted for not making novel predictions that are surprising, risky, and correct. I argue that it in fact exhibits the theoretical virtue of predictive capacity in addition to two other virtues: explanatory unification and model fitting. Two case studies show the predictive capacity of selectionist evolutionary theory: parallel evolutionary change in E. coli, and the origin of eukaryotic cells through endosymbiosis.

Analytical categories of scientific cultures have typically been used both exclusively and universally. For instance, when styles of scientific research are employed in attempts to understand and narrate science, styles alone are usually employed. This article is a thought experiment in interweaving categories. What would happen if rather than employ a single category, we instead investigated several categories simultaneously? What would we learn about the practices and theories, the agents and materials, and the political-technological impact of science if we analyzed (...) and applied styles, paradigms, and models simultaneously? I address these questions in general and for a specific case study: a brief history of systematics. (shrink)

In the 1940s and 1950s, nuclear magnetic resonance , one of the most important analytical techniques in chemistry, grew to maturity in the intermediate research field of chemical physics. Chemists and physicists adapted the new technology to the experimental culture of molecular spectroscopy which was based on a pragmatic experimental style. In molecular spectroscopy, the purpose of experiments was the establishment of methods that suited both the physicists' quest for precision and theoretical model building and the chemists' longing for empirical (...) data and understanding of structural formulae and reaction courses. In this process, an experimental style emerged that can be characterized as reliance on self‐built instrumentation, theoretical foundation in quantum mechanics, and proof of utility in the solution of structural and dynamical questions. This article focuses on the early development of NMR at Harvard University, with particular emphasis on the contributions of the first chemist working in the field of NMR, Herbert S. Gutowsky.

The continental drift controversy has been deeply analysed in terms of rationalist notions, which seem to find there a unique topic to describe the weight of evidence for reaching consensus. In that sense, many authors suggest that Alfred Wegener’s theory of the original supercontinent Pangea and the subsequent continental displacements finally reached a consensus when irrefutable evidence became available. Therefore, rationalist approaches suggest that evidence can be enough by itself to close scientific controversies. In this article I analyse continental drift (...) debates from a different perspective which is based on styles of thought. I’ll argue that continental drift debate took much longer than it was usually recognized with two styles of thought coexisting for hundreds of years. These were fixism and mobilism and they were always confronting their own evidence and interpretations and functioning as general frameworks for the acceptability of a specific theory. Therefore, this text aims to bring much broader sociological elements than usually involved in the analysis of the continental drift theory. (shrink)

Der Artikel führt den Begriff der epistemischen Konkurrenz ein. Im Gegensatz zu „wissenschaftliche Kontroverse“ beschreibt er eine Situation, in der sich zwei Forschungsfelder gegenseitig als mit demselben Bereich von Phänomen befasst wahrnehmen, wobei ihre methodischen Ansätze und theoretischen Erklärungen jedoch so unterschiedlich sind, dass ein offener Konflikt über die Wahrheit oder Falschheit bestimmter Aussagen oder die Genauigkeit in der Anwendung einer Methode nicht stattfindet. Nichtsdestotrotz streben beide Parteien danach, die maßgebliche Erklärung der entsprechenden Phänomene anzubieten. Indem die erweiterte Gemeinschaft der (...) Forschenden oder die Öffentlichkeit einen Ansatz als maßgeblich anerkennt, handeln sie als eine dritte, gewissermaßen neutrale Partei, die einen Preis vergibt, um den die anderen Parteien konkurrieren. Der Artikel beschreibt das Verhältnis von Genetik und Entwicklungsbiologie um 1900 als epistemische Konkurrenz. Diese Forschungsfelder geben unterschiedliche Erklärungen für die Phänomene der organischen Reproduktion. Die Erklärungen unterscheiden sich bezüglich der Formbegriffe und entsprechend hinsichtlich der Begriffe der Vererbung von Aspekten der Form eines Organismus. Zudem basieren die Erklärungen der beiden Felder auf unterschiedlichen Arten kausalen Schließens, die in unterschiedliche experimentelle Ansätze eingebettet sind. Diese Unterschiede können als Instanzen eines allgemeineren Unterschieds zwischen der Tradition der Naturgeschichte, die sich mit Unterschieden zwischen Organismen auseinandersetzt, und der Tradition der Anatomie, die sich mit den Teilen der Organismen beschäftigt, angesehen werden. Dieses Bild der Genetik und Entwicklungsbiologie als Zweige unterschiedlicher fest verankerter Traditionen widerspricht dem Narrativ der Trennung des Begriffs der Vererbung von dem der Entwicklung im Zuge einer Trennung der Disziplinen der Genetik und der Embryologie, das in der Historiographie der Biologie nach wie vor weit verbreitet ist.

Emphasis on cutting edge science is common today. This paper shows that the concept, which selects some science at any given time as epistemically preferable and therefore better, actually gained acceptance by the turn of this century in biology and began immediately to have consequences for what biological research was done. The result, that some research is cut out while other work is privileged, can have pernicious results. Some of what is designated as not cutting edge may, in a different (...) — and equally defensible epistemological framework, prove just as good as the officially cutting edge research. Cutting edges cut both ways, and those who study science should begin exploring the implications of that fact. (shrink)

Approaching science by considering the epistemological virtues which scientists see as constitutive of good science, and the way these virtues trade-off against one another, makes it possible to capture action that may be lost by approaches which focus on either the theoretical or institutional level. Following Wimsatt (1984) I use the notion of heuristics and biases to help explore a case study from the history of biology. Early in the 20th century, mutation theorists and natural historians fought over the role (...) that isolation plays in evolution. This debate was principally about whether replication was the central scientific virtue (and hence the ultimate goal of science to replace non-experimental evidence with experimental evidence) or whether consilience of inductions was the central virtue (and hence, as many kinds of evidence as possible should be pursued).

In modern discourse about the history of science, it seems to be widely accepted that at the end of the nineteenth century, Germany was one of the leading countries in the production of science. In the past, historians of science tried to trace back a specific ‘German style’ of science that—in combination with other factors—determined this German dominance around 1900, especially in the life sciences. Considering the theoretical concept of ‘national styles’, it has to be kept in mind that around (...) 1900, contemporaries already proclaimed ‘national styles’ of science as representations of national identity. Thus, the question arises as to how far existing historiographical conceptions of national styles may include earlier claims and prejudices. Careful reconstructions of contemporary discourses on national styles and inquiries into the ‘stylisation’ of a dominant, successful ‘German style’ are necessary. One of the contemporary critics of a ‘German style’ of science was the physiologist Jacques Loeb (1859–1924), who emigrated to the USA in 1891. Loeb corresponded regularly with the physicist and philosopher Ernst Mach (1838–1916). Ernst Mach can be considered Loeb's intellectual father with whom he corresponded about strategic, philosophical, and epistemological questions. Using the Loeb–Mach correspondence, the aim of the paper is to reconstruct Loeb's conception of a ‘German style’ of science and its differences to an ‘American style’. Changes in his views are discussed as well as the roots of his views and some of their consequences. Finally, Loeb's ideas on national styles and his working profiles before and after his emigration are compared to historiographical analyses of ‘American’ or ‘German’ styles of science around 1900.

This paper discusses essential elements of the philosophical works of Ludwik Fleck and their potential interpretation for the teaching and learning of science. In the early twentieth century, Fleck made substantial contributions to understanding the sociological character of the nature of science and explaining the embedding of science in society. His works have several parallels to the later and very popular work, The Structure of Scientific Revolutions, by Thomas S. Kuhn, although Kuhn only indirectly referred to the influence of Fleck (...) on his own theories. Starting from a short review of the life of Ludwik Fleck, his philosophical work and its connections to Kuhn, this paper elaborates upon and illustrates how his theories can be considered for science education in order to provide learners with a better understanding of the nature of scientific endeavor and the bi-directional science-to-society links.

Despite the controversial nature of studies of reproductive phenomena, a major center of reproductive biology emerged and coalesced in the Department of Zoology at the University of Chicago circa 1892–1940. Led by Frank R. Lillie, several small groups of researchers pioneered the study of sex determination and sex hormones, pursuing these via a Chicago approach to framing biological practice at both cellular and organismic levels. They worked in an interdisciplinary manner, however much in tandem, and drew strongly on local resources—from (...) the stockyards to local philanthropy. Most remarkably, Lillie redirected the mission of the major National Research Council Committee for Research Problems of Sex to address the biology of sex and then garnered about a fifth of its funds for Chicago. He thus guided Chicago biology into the fully modern era of external support for on-campus research and elaborate national scientific networks via promising biological solutions to social problems.

This paper aims to provide a fresh historical perspective on the debates on vitalism and holism in Germany by analyzing the work of the zoologist Hans Spemann (1869–1941) in the interwar period. Following up previous historical studies, it takes the controversial question about Spemann’s affinity to vitalistic approaches as a starting point. The focus is on Spemann’s holistic research style, and on the shifting meanings of Spemann’s concept of an organizer. It is argued that the organizer concept unfolded multiple layers (...) of meanings (biological, philosophical, and popular) during the 1920s and early 1930s. A detailed analysis of the metaphorical dynamics in Spemann’s writings sheds light on the subtle vitalistic connotations of his experimental work. How Spemann’s work was received by contemporary scientists and philosophers is analyzed briefly, and Spemann’s holism is explored in the broader historical context of the various issues about reductionism and holism and related methodological questions that were so prominently discussed not only in Germany in the 1920s.

This article explores the collaborative research of the Nobel laureate Hans Spemann (1869–1941) and the Swiss zoologist Fritz Baltzer (1884–1974) on problems at the intersection of development and heredity and raises more general questions concerning science and politics in Germany in the interwar period. It argues that Spemann and Baltzer’s collaborative work made a significant contribution to the then ongoing debates about the relation between developmental physiology and hereditary studies, although Spemann distanced himself from _Drosophila_ genetics because of his anti-reductionist (...) position. The article analyzes how Spemann framed the issues of heredity in terms of an epigenetic principle in the context of his work on the “organizer,” and it explores the experimental dynamics of research on newt merogones carried out by Baltzer in a methodological development of Spemann’s constriction experiments. Finally, these research attempts are discussed as part of a broader “prehistory” of the mid-twentieth century cell nuclear transplantation experiments, which provided the basis for later animal cloning.

This paper examines the very disparate positions that various actors have taken towards the argument of subversion from within in a set of related debates on group selection, altruism and the handicap principle. Using this set of debates as a case study, this paper argues that different applications of epistemic values were one of the factors behind the disagreements between John Maynard Smith and Amotz Zahavi over a number of important evolutionary issues. The paper also argues that these different applications (...) were connected to important epistemological differences related in part to their disciplinary background. Apart from conflicting evolutionary views concerning the theoretical feasibility of the handicap effect, these antagonists both differed in the confidence they ascribed to mathematical modeling and over the hereditary basis for altruistic behavior.

This paper provides a brief comparative overview of the development of the reproductive sciences especially in agriculture in the UK and the US. It begins with the establishment by F. H. A. Marshall in 1910 of the boundaries that framed the reproductive sciences as distinct from genetics and embryology. It then examines how and where the reproductive sciences were taken up in agricultural research settings, focusing on the differential development of US and UK institutions. The reproductive sciences were also pursued (...) in medical and biological settings, and I discuss how the intersections among all three allowed the circulation of both ideas and scientists’ careers. Across the twentieth century, scientific leadership in the reproductive sciences alternated between the UK and US, and these patterns are elucidated. I conclude with thoughts on future research that might emphasize the elaboration of industrialization processes in agriculture and new capacities to transform both reproductive processes and their products—life itself—as biopower comes to be more ambitiously understood as extending across all species.

Evo-Devo exhibits a plurality of scientific “cultures” of practice and theory. When are the cultures acting—individually or collectively—in ways that actually move research forward, empirically, theoretically, and ethically? When do they become imperialistic, in the sense of excluding and subordinating other cultures? This chapter identifies six cultures – three /styles/ (mathematical modeling, mechanism, and history) and three /paradigms/ (adaptationism, structuralism, and cladism). The key assumptions standing behind, under, or within each of these cultures are explored. Characterizing the internal structure of (...) the cultures is necessary for understanding how they collaborate or compete, and how they are fragmented or integrated, in the rich interdisciplinary /trading zone/ (Galison 1997) of Evo-Devo. Evo-Devo is an important example of how science can progress through a radical plurality of perspectives and cultures. (shrink)
