According to Fleck, a fact is not something objectively given but rather a social event. Scientific facts are no exception, as can be seen through the annals of medicine. Fleck argues that if the physical sciences initially appear to be immune to such social conditioning, this misconception can be corrected by recognizing the similarities between the natural sciences and medicine both historically and epistemologically. Fleck's ideas are not new, having been presented by him in 1935, but it is only recently (...) that they have begun to strike a responsive chord. Kuhn was aware of Fleck's work when he began to promulgate his own ideas in the 1960s. But there are important differences as well as similarities which can only be appreciated once Fleck's own work has had a proper hearing. To this end the University of Chicago Press has published a translation-edition of the full monograph in 1979. In ‘On the question of the foundations of medical knowledge’, Fleck's own precis to this major work, he correctly foretold the dawning of the sociology of cognition.

A scientific community cannot practice its trade without some set of received beliefs. These beliefs form the foundation of the "educational initiation that prepares and licenses the student for professional practice". The nature of the "rigorous and rigid" preparation helps ensure that the received beliefs are firmly fixed in the student's mind. Scientists take great pains to defend the assumption that scientists know what the world is like...To this end, "normal science" will often suppress novelties which undermine its foundations. Research (...) is therefore not about discovering the unknown, but rather "a strenuous and devoted attempt to force nature into the conceptual boxes supplied by professional education". (shrink)

This article argues that Ludwik Fleck’s understanding of scientific observation as a social and cultural process stemmed not only from his practical experience as a bacteriologist and serologist, but also from a confrontation with ideas developed by other Polish thinkers. It discusses ideas of three such thinkers: the ophthalmologist and philosopher of medicine Zygmunt Kramsztyk, the mathematician and painter Leon Chwistek, and the playwright, painter and photographer Stanislaw Ignacy Witkiewicz. Kramsztyk was interested in the way the observer’s preconceived idea shaped (...) observations through selection of specific visual elements and the rejection of others. Chwistek developed a theory of ‘multiple realities’ which proposed several divergent and equally valid patterns of grasping reality. In his plays, photographs, drawings and paintings Witkiewicz experimented restlessly with destabilization and transformation of the notion of a stable external reality. It links, then, debates on ‘reality’ in Poland between 1900 and 1939 to intersections of ideas derived from modern physics, psychology of perception, and avant-garde art.Keywords: Ludwik Fleck; Stanislaw Ignacy Witkiewicz ; Leon Chwistek; Poland; Perception; Avant-garde art.

Thomas S. Kuhn's classic book is now available with a new index.

This article analyses three basic concepts of Ludwik Fleck’s Genesis and Development of a Scientific Fact. It shows first that Fleck’s notion of „directed perception“ is closely linked to Jakob von Uexküll’s writings on the „Umwelt“ of animals and humans. The article then proposes to regard the epistemological debates surrounding parapsychology as an important testing ground for the Fleckian concept of „mood“ and his concomitant hypotheses about „the tenacity of systems of opinion and the harmony of illusions“. It finally argues (...) that Fleck’s modification of Wilhelm Jerusalem’s idea of the „social consolidation“ of knowledge helps us to understand the indebtedness of Fleck towards early functionalist sociology as well as his strong belief in „specific historical laws governing the development of ideas“. The historical semantics of Fleck’s works hence proves that his insights are neither marginal nor revolutionary but rather deeply rooted within scientific traditions from the late 19th and early 20th centuries.

This article argues that the limited influence of Ludwik Fleck's ideas on philosophy of science is due not only to their indirect dissemination by way of Thomas Kuhn, but also to an incommensurability between the standard conceptual framework of history and philosophy of science and Fleck's own more integratedly historico-social and praxis-oriented approach to understanding the evolution of scientific discovery. What Kuhn named "paradigm" offers a periphrastic rendering or oblique translation of Fleck's Denkstil/Denkkollektiv , a derivation that may also account (...) for the lability of the term "paradigm". This was due not to Kuhn's unwillingness to credit Fleck but rather to the cold war political circumstances surrounding the writing of The Structure of Scientific Revolutions . Following a discussion of Fleck's anatomical allusions, I include a brief discussion of Aristotle (on menstruation and darkened mirrors) and conclude with a reference to the productivity of error in Mach and Nietzsche.

Unlike human beings, landscapes, cities and buildings cannot feel anything in the literal sense. They do not have nervous systems. Nevertheless, we attribute “Stimmungen” such as peacefulness and melancholy to them. On what basis? With what right? And why does it matter anyway? This paper attempts an answer to this bunch of questions. The first section clarifies the concept of “Stimmung,” by distinguishing its three major meanings, namely harmony, mood and atmosphere. Section two discusses various models of how “Stimmung” is (...) infused into our natural and artificial environment. Section three lists several ways of how we experience atmosphere, preparing the ground for the specifically aesthetic claim in section four: how, when we experience atmosphere aesthetically, we respond to it by resonating or feeling at home.

This ambitious book by one of the most original and provocative thinkers in science studies offers a sophisticated new understanding of the nature of scientific, mathematical, and engineering practice and the production of scientific knowledge. Andrew Pickering offers a new approach to the unpredictable nature of change in science, taking into account the extraordinary number of factors—social, technological, conceptual, and natural—that interact to affect the creation of scientific knowledge. In his view, machines, instruments, facts, theories, conceptual and mathematical structures, disciplined (...) practices, and human beings are in constantly shifting relationships with one another—"mangled" together in unforeseeable ways that are shaped by the contingencies of culture, time, and place. Situating material as well as human agency in their larger cultural context, Pickering uses case studies to show how this picture of the open, changeable nature of science advances a richer understanding of scientific work both past and present. Pickering examines in detail the building of the bubble chamber in particle physics, the search for the quark, the construction of the quarternion system in mathematics, and the introduction of computer-controlled machine tools in industry. He uses these examples to address the most basic elements of scientific practice—the development of experimental apparatus, the production of facts, the development of theory, and the interrelation of machines and social organization.

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.
