Ludwik Fleck (1896-1961) was a bilingual academic conversant with the medical and philosophical vocabulary in both Polish and German. This paper pays tribute to Fleck’s academic bilingualism and focuses on his uses of images in the original versions of his epistemological works “Some Specific Features of the Medical Way of Thinking” (1927), “Crisis of Reality” (1929), “Scientific Observation and Perception in General” (1935) and “To Look, To See, To Know” (1947). Images are understood as actual artifacts as well as literary (...) metaphors that structure Fleck’s thinking on epistemology. By examining Fleck’s rhetoric in the original Polish and German versions of these texts this paper unfolds the multifaceted meanings and connotations of the various image metaphors and illuminates the rhetoric impact of Gestalt psychology on Fleck’s ideas on cognition.

The rediscovery in the mid-1970s of Ludwik Fleck's initially neglected monograph, Entstehung und Entwicklung einer Wissenschaftlichen Tatsache, published in 1935 and translated in 1979 as Genesis and Development of a Scientific Fact, has resulted in extensive, still ongoing, secondary writings, mainly within the humanities. Fleck has been interpreted as furthering a relativistic conception of science. Nowadays, he is often viewed as an important contributor to contemporary sociology of science and a forerunner to Thomas Kuhn. Fleck's account of the Wassermann reaction, (...) which forms the basis of his epistemology, has been praised as developed by a scientist well acquainted with the field in question. Because of the scarcity of available material on Fleck, however, the question of his sources has remained an unsolved issue. In the present article, an alternative reading is suggested. By focusing on the scientific content of the monograph, mainly neglected in the modern interpretations of Fleck, and on the so far overlooked sources of his writings traced back to their German origin, a better understanding of Fleck's account of the Wassermann reaction can be given. The consequences of this alternative reading for the conception of Fleck's monograph and for the impetus of his mission are discussed. (shrink)

This paper is a criticalexamination of the development of thephilosophy of medicine as a discipline. Ithighlights two major themes in the contemporarydebate about the philosophy of medicine: thescope of the discipline and the relation of thediscipline to its cognate disciplines. A broadview of the philosophy of medicine is defendedand the philosophy of medicine is seen as aphilosophical sub-discipline. These viewsdepend in important ways on three factors: ageneral metaphysical world view, particularunderstandings of the cognate disciplines, andthe perspective from which one asks (...) thequestions about the nature of the discipline. It is proposed that the future of thephilosophy of medicine may follow thephilosophy of science in that philosophical,sociological and historical studies may combinein a mutually enriching way to form ‘‘medicinestudies.’‘.

Ludwik Fleck’s theory of thought-styles has been hailed as a pioneer of constructivist science studies and sociology of scientific knowledge. But this consensus ignores an important feature of Fleck’s epistemology. At the core of his account is the ideal of ‘objective truth, clarity, and accuracy’. I begin with Fleck’s account of modern natural science, locating the ideal of scientific objectivity within his general social epistemology. I then draw on Fleck’s view of scientific objectivity to improve upon reflexive accounts of the (...) origin and development of the theory of thought-styles, and reply to objections that Fleck’s epistemological stance is self-undermining or inconsistent. Explicating the role of scientific objectivity in Fleck’s epistemology reveals his view to be an internally consistent alternative to recent social accounts of scientific objectivity by Harding, Daston and Galison. I use these contrasts to indicate the strengths and weaknesses of Fleck’s innovative social epistemology, and propose modifications to address the latter. The result is a renewed version of Fleck’s social epistemology, which reconciles commitment to scientific objectivity with integrated sociology, history and philosophy of science. (shrink)

Kollaboration und Konkurrenz gibt es in der Wissenschaft zwischen Individuen oder verschiedenen Gruppen, größeren Organisationen, Schauplätzen und Nationalstaaten. Die Spannung zwischen individuellem Ansehen und Gruppenmeriten oder individuellem Ehrgeiz und Gruppenleistung ist der wissenschaftlichen Arbeit inhärent und trägt zu ihrem Erfolg bei. Die Autorin vergleicht zwei soziale Modelle der Wissenschaft, die entwickelt wurden, als Wissenschaftler im 20. Jahrhundert zunehmend begannen kollaborativ zu forschen: Michael Polanyis individualistische Freie-Markt-Republik der Wissenschaft und Ludwik Flecks Denkkollektiv. Diese beiden Modelle sollten Praktiken beschreiben und Ideale für (...) die Wissenschaft im allgemeinen auf der Grundlage der Erfahrungen spezialisierter Forschungsgruppen vorschreiben. Die Arbeitsgruppen von Linus Pauling und Dorothy Crowfoot Hodgkin dienen hier der Erläuterung der beiden Modelle. Die Autorin untersucht verschiedene Auswirkungen von Paulings und Hodgkins Praktiken auf das persönliche Ansehen des Direktors und der Mitarbeiter, und schließt mit der Frage, ob eine kollektive Wissenschaft möglich ist.

This article traces some of the transformation that the fields of folk psychology and anthropology underwent in the late nineteenth century. Ludwik Fleck, in developing his sociology of knowledge, drew on both of these fields; a legacy that makes it possible to conceive of his epistemology as a theory of communication. Fleck, in grounding his understanding of the relationship between sociality and communication on insights from these two disciplines, proposed the morphological concept of an organic formation of all scientific knowledge. (...) Naturalising knowledge production in this manner, Fleck postulated a program of deciphering, reading, and translation that would relate all forms of knowledge back to the rules and conditions of its making. In this morphological conception of the processes of knowledge production, Fleck’s sociology bears significant similarities with the description of social institutions by French sociologists Marcel Mauss and Emile Durkheim, who also drew on insights from late-nineteenth-century folk psychology and anthropology.

This article has three objectives: First, it revises the history of the reception of Ludwik Fleck’s monograph Entstehung und Entwicklung einer wissenschaftlichen Tatsache (1935, Genesis and Development of a Scientific Fact). Contrary to the established picture, Fleck’s book was largely discussed in the years before the outbreak of World War II. What becomes clear when reading these early reviews and especially Fleck’s comments to those written by representatives of Nazi Germany is, second, the political dimension of his epistemology. In this (...) respect, Fleck’s emphasis on the genuinely democratic character of science will be discussed in some detail. And third, Fleck’s notion of “ Denkstil ”—thought-style—shall be examined more closely since, as we will claim, it can be understood as a notion indicating where the democratic dimension of science encounters its limits.
