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.     

“Lachkabinett” und “großes Fest” der Physiker. Walter Grotrians “physikalischer Einakter” zu Max Plancks 80. Geburtstag

“Funhouse” and “Big Celebration” of the Physicists. Walter Grotrian's ?Physical One‐Act Play”? for Max Planck's 80th Birthday. On the occasion of Max Planck's 80th birthday on April 23, 1938, a “big celebration of the physicists” (großes Fest der Physiker) was celebrated at the Harnack‐House in Berlin. The festivities were organized by the German Physical Society. Part of the ceremony was a “Physical One‐act‐play” (Physikalischer Einakter) written by the Potsdam astrophysicist Walter Grotrian. The actors of the humorous play were chief protagonists in the development of quantum theory such as Debye, Sommerfeld and Heisenberg. In this essay we analyze Grotrian's drama against the background of both the festive event and the professional and social setting of the physicists. We argue that below the level of comedy a number of characteristic and normally unexpressed aspects of the epistemic culture of the German physics by the end of the nineteen‐thirties is treated in the play.     

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.     

Theophrast über Pflanzenkrankheiten. Ein Beitrag zur Geschichte der Phytopathologie in der Antike

Already before Theophrastus there was a botanical literature which also dealt with the diseases of plants, but we have only indirectly access to it — mainly by way of Theophrastus. The botanical excursus of the Hippocratic series of writings De genitura, De natura pueri, De morbis IV, which attributes the health of plants to a balance of warmth and cold and a correct quantity of specific humidity, forms an exception. This excursus hints at what is more fully developed in Theophrastus discussion of the diseases of plants: The diseases of plants are understood in close analogy to those of animals or human beings. In both cases, a basic distinction is made between inner, dietetic diseases and outer, traumatic ones. According to Theophrastus, especially humidity and an innate warmth are life-sustaining factors. A disturbance of the natural humidity/warmth-household must be counteracted by respective measures. As far as the terminology of plant diseases is concerned, Theophrastus relies on already existing concepts. Classical literature after Theophrastus has made no substantial contributions to phytopathology.     

Von Vielschichtigkeiten und Verschränkungen “Kulturen der Wissenschaft – Wissenschaften in der Kultur”

On Multiple Levels and Linkages: Introduction to the Symposium ‘Cultures of Sciences – the Sciences in Culture’. – The article presents briefly approaches to cultural history and cultural studies that seem potentially useful to or have recntly been applied in historical studies of the sciences. The first section discusses three such approaches: discourse analysis, symbolic artefacts (images and text), and cultures of scientific practice. Each of the three approaches raises issues of its own, and all of them share a common problem characteristic of cultural and social history in general: linking micro and macro levels of analysis. The second section presents three approaches to resolving this dilemma by focusing on specific linkages between cultures of science (or culture in the sciences) and general history: scientific thought and practice as norms for professional behavior, for example in fields of knowledge dominated by women; spaces of knowledge, for example the city; and linkages of cultural, media and economic history in fields such as radio and television.     

Das erste zoologische Kompendium in der Zeit der Renaissance: Edward Wottons Schrift „Über die Differenzen der Tiere”︁

The English physian Edward Wotton wrote the first zoological compendium in the time of the Renaissance. As a convinced representative of Renaissance-Humanism Wotton strictly applied Aristotelian methodological principles to Aristotelian facts. In this way he tried to make Classical Antiquity complete; the Renaissance of ancient zoology is here tantamount to a new beginning. Wotton's achievement is in the first place to have provided a good summary of the whole of ancient zoological knowledge to which he added a few observations of his own. He carried through the Aristotelian concept of differentiation by many distinguishing features more strictly than Aristotle himself and all subsequent authors. In this way he attained the first zoological system, which influenced all later systematic attempts. The main Aristotelian groups are further subdivided and the Zoophyta are separated for the first time as an independent group. Wotton used a practical indexation method and got rid of an excess of detail in the text, adding critical annotations to each chapter. By means of the two indices, one of the names and the other of the parts of animal, Wotton tried to improve the precision of nomenclature and by this the identification of the objects under examination. His critical position on fabulous animals reveals his progressive mind.
