Der kundige Laie und das naturkundliche illustrierte Flugblatt der frühen Neuzeit

The aim of this paper is to demonstrate how German and Latin illustrated broadsheets of the sixteenth and seventeenth centuries can serve as documents of the history of sciences and the dissemination of scientific knowledge. It shows how broadsheets were used as a means of conveying scientific observations and conclusions not only among scholars versed in Latin but, through the medium of the vernacular, between scholars and laymen, too. In the fields of medicine, astronomy, zoology and botany in particular, the illustrated broadsheet facilitated the rapid circulation of case histories and accounts of various scientific phenomena. Furthermore, it played an important role in breaking down the barriers that separated the scholar from the layman, who was otherwise far removed from the world of books.     

„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.     

Globaler Pflanzentransfer und seine Transferinstanzen als Kultur‐, Wissens‐ und Wissenschaftstransfer der frühen Neuzeit

In three steps, the polyvalent phenomenon of global plant transfer will be analysed. Starting from the model of cultural transfer, the latter one will be discussed in combination with network research. Finally, the connection of various instances of transfer such as botanical gardens, ships and islands will be established. The fact that botanists take part in the process of transfer increasingly and from the middle of the 18th century onwards control the plant transfers in all phases emphasises the entwinement of science and colonialism.     

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 Idee einer historischen Entwicklung der Krankheiten des Menschengeschlechts und ihre Bedeutung für die empirische Medizin des frühen 19. Jahrhunderts

In early 19th-century German medicine many doctors had a strong interest in historical pathology. They investigated the historical records of fevers and epidemics in detail, trying to find out how the changing influence of the epidemic constitution worked and hoping that history would help them to define specific disease entities. The underlying theory of this endeavour was that diseases undergo a historical development similar to the evolution of plants and animals. This paper tries to show that historical pathology was, in its time, a legitimate attempt to solve the most urgent problems of empirical medicine.     

“… 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.     

„Siege der Freiheit,welche die Menschen durch die Erforschung des Grundes der Dinge errangen”︁ Wandlungen im politischen Selbstverständnis deutscher Naturwissenschaftler des 19. Jahrhunderts

“Victories of Freedom which Humans Achieved by Research in the Foundation of Things”. - This article analyzes the political self-conception of leading representatives of the natural sciences in 19th century Germany. It is argued that the main feature of this self-conception which remained constant over the time consisted in a strong “rationalization-imperative”, i.e. the postulate that state and society have to be reshaped on the basis of natural science. On the other hand, this imperative was put forward in very different forms and with different political content: it shifted from revolutionary aspirations in the period of 1848 to moderate and sometimes even reactionary positions in the last decades of the century.     

„Und nur die Zukunft wird Klarheit bringen!”︁Der Fall des Biomediziners Jacques Benveniste aus dem Jahr 1988 im Blickfeld der wissenschaftlichen Publikationsorgane und der Laienpresse

Scientific disputes on the objectivity of research results are an integral part of the collective production of knowledge. One motivation to study cases of scientific controversy is the attempt to discover general patterns in the behaviour of participants and institutions involved in such controversies. Yet, for there to be a controversy, one must assume an important amount of social interaction, so much so that it renders it an essentially social phenomenon, which is accessible to historical study. Cases of obvious scientific fraud, in addition, are neither clear‐cut nor rare and the mere accusation of scientists by their peers frequently constitutes considerable examples of scientific debate. Together with this, it is often assumed that publication organs play a dominant role in directing the lines of scientific controversy, but their institutional significance and the task of individual editors remain widely unexplored. The present article studies the prominent Nature affair of the Parisian biomedical scientist Jacques Benveniste, both, from a perspective on scientific fraud and on the beginning and closure of scientific disputes. One of the most remarkable features of Benveniste's antibody dilution experiments was that they stroke at the foundations of modern physical and biomedical sciences. Could recent history of science actually resolve the case of the so‐called ‘memory of water’ phenomenon?     

„On employera les meilleurs Graveurs pour les Figures”︁. Zeichner und Stecher der Berliner Akademie der Wissenschaften, 1700–1806

“We will employ the best engravers for the figures” – Draughtsmen and Engravers of the Berlin Academy of Sciences, 1700–1809. – Although barely mentioned in accounts of its history of the Berlin Academy of Sciences, draughtsmen and engravers were, from the very inception, essential collaborators. Based on previously overlooked archival sources, this paper investigates the strategies that scientists used to select the most appropriate candidates during the first hundred years of the academy's existence. These included: (1) the engaging of artists already known to the scientists or those who had been recommendaded to them; (2) maintaining long‐term relationships with a number of artists, and later with their offspring (who had frequently been trained by their fathers); in 1768 this strategy culminated in the creation of a permanent position for one academic draughtsman; and (3) hiring draughtsmen who specialised in the subject matter in question, which entailed, for example, employing different people to carry out anatomical and botanical illustrations.     

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 wissenschaftliche Ausbildung des Arztes ist eine Culturfrage …”. Über das Verhältnis von Wissenschaftsanspruch,Bildungsprogramm und Praxis der Medizin

The article shows that the elite, nationalistic and imperial mentality of German medicine in the second half of the nineteenth century was closely connected to its aim to be understodd as a natural science. With this in view leading representatives of German medicine propagated a scientific approach to man and nature instead of the traditional values of humanistic education (“Bildung”). One of the most important consequences of the new scientific ideal in medicine — integration in governmental planning, the change in professionel status of doctors, the increasing tendeny to recognize biologistic ideologies — was the loss of the medical ideal of the ars medica, a subject which has not received sufficient thematic attention. This theme is explored in the third part of the article.     

Zur frühen Geschichte der Paläocheloniologie von Schaumburg‐Lippe. Die Rolle des Gymnasial‐Professors Max Ballerstedt in der Naturwissenschaft

A survey is given on some new aspects of the early history to the palaeochelonology in Schaumburg‐Lippe (Northern Germany). The very slow development of this is good reconstructable on base of authentic estates. It is the first time to made such a nearly complete reconstruction.     

Die Rezeption der humanistischen Gedächtnislehre bei Luther: Natur,Kunst und Konfessionen

Iconoclasm is one of the central characteristic of the reformation movement. In several books it was argued that there was a connection between iconoclasm and the interpretation of nature as a language and as a text since about 1600. This article discusses the artist as a creator in Renaissance culture. It shows the reaction of Luther to this concept and to iconoclasm, focussing on the connection between the Lutheran control of pictures and images and his conception of the mind and of memory on the one hand and of creatures as images and natural history on the other. In Lutheran context the book of nature was a book made of images as signs of the word of God.     

Analogie und mathematisches Denken

This article deals with six aspects of analogical thinking in mathematics: 1. Platonism and continuity principle or the “geometric voices of analogy” (as Kepler put it), 2. analogies and the surpassing of limits, 3. analogies and rule stretching, 4. analogies and concept stretching, 5. language and the art of inventing, 6. translation, or constructions instead of discovery. It takes especially into account the works of Kepler, Wallis, Leibniz, Euler, and Laplace who all underlined the importance of analogy in finding out new mathematical truth. But the meaning of analogy varies with the different authors. Isomorphic structures are interpreted as an outcome of analogical thinking.
