„Und setzet eure Worte nicht auf Schrauben”︁ Medizinische Semiotik vom Ende des 18. bis zum Beginn des 20. Jahrhunderts - Gegenstand und Forschung

There is no doubt that medical semiotics are having a revival at the moment. Different aspects of yesterday's and today's interest in semiotics and in the historical interpretation of signs of disease in the context of theory and history of medicine can be illuminated: their deciphering as the history of the sign in medicine by historic science, their overestimation by philosophy during the Age of Enlightenment, their reduction to a phenomenology of medicine and natural science during the first half of the 19th century and their transformation to medical diagnostics since the middle of the 19th century and recently even their functionalization as methodical instrument within the history of science. The following will show the change in meaning of medical semiotics. Modern development and especially the transition to medicine, based on natural science, will be emphasized.     

Von der „Natur der Sache”︁ zur Geschichte der Sprache Der Übergang von der Sprachforschung zur Sprachwissenschaft zu Beginn des 19. Jahrhunderts

From the “nature of things” to the history of language: The transition from the study of language to historico-comparative linguistics. This brief essay deals with a somewhat problematic phase in the history of linguistics and tries to investigate the process by which language could be understood as a historical phenomenon with a history of its own. This new understanding of language turned out to be the starting condition for a new and very prolific way in the study of language. The conjecture is that this is due to certain alterations in the semantic field of some important notions relating to language and its study. The process of alteration began by the end of the eighteenth century with conceptual achievements which could adequately be termed as temporalization of aspects of language and the notions related to these aspects. In connection with the so called discovery of the Sanskrit language and the gradual reception of its grammatical structure, looking upon language as an organic entity with autonomous and internal structures of developpement became possible after the German romantic language philosophy had developped a strictly abstract concept of language as a notion of form. This essentially metaphorical mode of speaking nevertheless inaugurated that languages were concieved of as having their own history totally independent of their speakers. With language as an autonomous object the study of language rapidly became the science of language.     

Die Gesellschaft Naturforschender Freunde zu Berlin ‐ Bestand und Wandel einer gelehrten Gesellschaft Ein Überblick

The article deals with the foundation and development of the society Gesellschaft Naturforschender Freunde zu Berlin in the 18th and 19th centuries, its position as a privat society for natural history in Berlin, and its relation to Freemasonry. The paper shows the change of meaning of these society, especially after the foundation of the Berlin university in 1810.     

Arbeit und Zeit,Körper und Uhr: Die Konstruktion von ‚effektiver’︁ Arbeit im ‚Scientific Management’︁ des frühen 20. Jahrhunderts

The concept ‚Scientific Management’︁ was invented in 1910 for what was then called the ‚Taylor‐system’︁ of shop management. Frederick W. Taylor had developed his system to eliminate the “waste of human effort” mainly by “time study”, the analysis of the work of “first‐class workman” with a stop‐watch and the synthesis of standard times for given tasks which make the “waste” of effort visible and measurable. A reading of Karl Marx's work shows the “paradigm of productivity” governing mid‐century discussion of the value of labor. Time is a central element in the valuation of industrial labour, but only with Taylor the precision of the stop‐watch is introduced to observe and control the productivity of the body of the worker. As disciples of Taylor Frank and Lillian Gilbreth introduced motion studies and micromotion studies into Scientific Management. Their analysis of the motion of workers, technically assisted by high‐speed watches and cameras, goes beyond the surface‐observation of the first‐class workman to enable the design of efficient motion. The body of the worker is represented in lines of light and tables of data. The objects of desire are the time‐lines of efficiency and productivity. In both cases, Taylor and the Gilbreths, various observations further lead to the conclusion that science and schooling are an important historical background to the rise of Scientific Management that deserves closer inspection.     

Von der Naturgeschichte zur Naturwissenschaft Die Naturwissenschaften als eigenes Fachgebiet an der Universität Jena

Since 1790, the term Naturwissenschaften occurs in the lecture lists of the University of Jena published in the Allgemeine Literatur-Zeitung of Jena. Naturwissenschaften is used as a title for lectures previously listed under the headings of Philosophie or Naturgeschichte. The introduction of the concept of Naturwissenschaften is interesting for several reasons: Firstly, at that time it is not the usual label in this context, and one therefore has to ask whether it already implies the connotations that are associated with the modern concept of Naturwissenschaften, i. e. science in the modern sense. Secondly, the lecture lists of the University of Jena give insight into the various changes in the established ordering scheme for academic lectures that lead to the introduction of the term Naturwissenschaften, thus contributing to a better understanding of both the history of this concept and of the development of the university faculties as we know them. A close look at the concept of Naturwissenschaften as it was used around 1800 may, thirdly, help to understand the use made of this concept in philosophy, especially in the philosophy of nature of this period.     

Zur Pluralisierung im Luthertum des 17. Jahrhunderts und ihrer Bedeutung für die Deutungen von ‚Natur’︁

Building on methodological considerations in cultural history and historical anthropology, the following contribution proceeds from the concept of ?nature’? rather than from ?natural science’?, with the former understood here as the object of culturally determined projections, values and practices. This ?constructive’?, practice‐oriented concept of nature exposes perceptions of and attitudes towards nature that, owing to the usual reduction of nature to natural science, would otherwise have remained hidden, but which may well be essential to its constitution. To a certain extent, the term ?nature’? continues the terminological extension from ?natural science’? to ?natural philosophy’?, but as a heuristic device it more strongly implies the significance of culturally mediated practices and dynamics. The essay raises the following questions: Which religious conceptions entered into which attitudes towards nature and which religious expectations and interpretive matrices were the motivating forces behind which studies of nature? The figures within seventeenth‐century Lutheranism who shaped and promoted nature‐oriented attitudes and practices were not the ?orthodox’? scholars more strongly tied to academic and controversialist theology, but rather reform‐oriented theologians critical of the church. In the context of the inner differentiation and pluralization of seventeenth‐century Lutheranism, these reform‐oriented groups not only inspired innovate theological projects but also assumed a leading role, along with liked‐minded Christian laypersons, in interpreting and studying ?nature’?.     

Die ‚Deutsche Physik’︁ in der Selbstkritik des NS‐Ideologen Alfred Bäumler

In 1944, the Nazi ideologist Alfred Baeumler wrote a memorandum for his boss Alfred Rosenberg, Adolf Hitler's commissioner for the political education of party members. In this sensational memo, which did not become known until long after 1945, Baeumler spoke out against the promotion of under‐performing physicists who oust highly‐qualified non‐Nazi scientists at the universities without submitting adequate research results. – Rosenberg's response is not known. What is known, however, is that Baeumler did not manage to change the situation criticised by him.     

Der Kampf gegen den „Schwarzen Tod”︁. Quarantäne und Epidemiebekämpfung der frühen Neuzeit im Mittelmeer aufgezeigt am Beispiel Maltas

During early modern period Mediterranean people feared epidemics far more than war and other destructive activities. Where epidemics, especially the plague, struck, all communications broke down and trade just withered away. With the coming of the Knights of St. John in 1530 the Maltese Islands became increasingly important as an international boarding place in the very center of the Mediterranean. Soon the maritime development of the Order's State was enhanced by the high regard in which the Maltese Quarantine System was held by European countries in the 17th and 18th century. The aetiology of plague was then unknown and the restrictive measures adopted by the Maltese Quarantine System too were in accordance with the approved epidemiological practices and theories of the time. This article tries to single out the importance of the Maltese Quarantine as a kind of medical “shield” for the southern European countries.     

Das Problem der “entscheidenden Experimente”

In this historical essay an attempt is made to discuss the problem of decisive experiments both from the point of view of History of Science and of Philosophy of Science. The first part deals with Francis Bacon's idea of instantiae crucis and with the use of the term experimentum crucis mainly in optics. With respect to the experimental confirmation of Maxwell's electrodynamics the Duhem-Quine Thesis is discussed. Duhem had argued that not a single hypothesis but only a complete theory is examined by experiment. So a single experiment neither can prove nor can disprove a single hypothesis. With regard to Bucherer's and Neumann's data concerning the velocity-dependence of the electron's mass the question of the certainty of conclusions arising from experimental tests is treated. In the last parts the really historical problem of the decisive experiments is considered, namely the gap between the context of design of an experiment and the context of evaluation of an experiment in retrospect. The examples here are the Michelson-Morley experiment, the Franck-Hertz experiment, and the Compton-Effect. In the conclusion parity violation is discussed. Perhaps due to the possibility of a single alternative in theory and an unambiguous result of the experiment this test really was crucial. In general, however, the experimentum crucis will prove to be a very seldom event.     

Die Apotheke als Forschungsstätte

From the beginning, next to their essential function of preparing drugs pharmacies also served as educational institutions, in particular for the instruction of their own rising generation. Especially between 1750 and 1850 pharmacies in addition were engaged in scientific research. It were basically experimental‐analytic chemistry and after 1800 mainly phytochemistry which inspired numerous apothecaries to do corresponding work in their laboratories. For many of those scientifically ambitious pharmacists, however, pharmacies were merely a starting point in their professional career. More or less rapidly, they turned to other places of activity which were organizationally, socially, and intellectually of higher standards (e.g. academies or universities). There, they were better able to realize their research interests frequently roused and shaped in the pharmacies. When around 1850 chemistry as an autonomous discipline definitely was established at the universities and competition became increasingly apparent through the rising chemical industry, the former meaning and function of pharmacies as places of scientific research disappeared more and more and was completely lost about 1900.     

“… daß der Liebhaber etwas Erfreuliches und Nützliches zu leisten im Stande ist.” Goethe,Soemmerring und das Os intermaxillare beim Menschen

Goethe's theoretical comments on the acknowledgement of the natural sciences dilettante differ considerably from his own experiences in this role (Farbenlehre, Zwischenkieferknochen) of dilettante. Therefore, it seems necessary to raise general questions on the concept: dilettante of natural sciences during Goethe's time, furthermore, on the characterization and labeling of such a dilettante in an historical-scientific context. This is especially important since up to the present time this particular problem has hardly ever been examined. In addition, there is a summary of an historical case study, the discovery of the human intermaxillary bone by Goethe and of the specialists' reactions on this discovery, especially that of Soemmerring.     

Die Fotografie – ein neues Bildmedium im Wissenschaftspanorama des 19. Jahrhunderts. Einführung in das Symposium

Photography – a novel medium of scientific representation in the XIXth century array of arts and sciences. To delve into various nineteenth century academic disciplines under the heading ‘photography in the arts and sciences’ as did last year's annual conference of the History of Science Society – the interest in such a topic only partly stems from the ‘iconic turn’ that has generally enlarged the scope of the social sciences in recent years. A more poignant feature in any such present day study will probably be a basic scepticism facing the fact that in public use photographs have been manipulated in many respects. Yet, while shying away from any simple success story, a historically minded approach to changing ‘visual paradigms’ (Historische Bildwissenschaft) has begun to emerge. In this context, it has proved of considerable heuristic value to reconsider the role of early photography in an array of science, arts and technology: Since the reliance on the traditional ways of sketching reality persisted, in many an instance where photography was introduced, the thoughts the pioneer photographers had about their new, seemingly automated business, call for close attention. Thus scholarship sets up a parallel ‘discussion room’; the lively debate on the benefit of academic drawings as opposed to photographic portraits is a case in point. Some fairly specialised reports on photographically based analyses, such as electron microscopy, point to a borderline where the very idea of representation as a correspondence of reality and imagination gets blurred. Even though any ‘visual culture’ will have to shoulder the ‘burden of representation’, it is equally likely that it will offer a deeper sensibility for the intricacies entailed in the variegated ways of illustrating or mapping chosen subjects of scientific interest. Scholarship may thus somewhat control the disillusionment that by now has become the epitome of writing on photographic history. Provided with a renewed methodological awareness for the perception process and its photographic transition, historians may strike a better balance between the ever present tendencies of a realistic and an aesthetic way of picturing the world we live in.
