Zeitschichten des Klons. Anmerkungen zu einer Begriffsgeschichte

Temporal Layers of the Clone. Remarks on a Conceptual History. This paper aims at a history of the clone concept in 20th‐century life science and culture. The first part of the paper is concerned with conceptual history approaches. Here, the idea of ‘Zeitschichten’ by Reinhart Koselleck is discussed and its implications for the history of science are explored. In the following parts of the paper, I trace the historical dynamics of the clone concept in various fields of 20th‐century life sciences. I argue that the clone concept, which originated in plant breeding around 1900, soon developed into a technical tool in a variety of research areas. With this, specific meanings became attached: the idea of standardization, genetic identity, and mass reproduction. A further connotation of the clone was the idea of stagnancy with respect to processes in time: The clone was seen as something that was exempt from evolutionary changes. In the last section of the paper, I trace the shifting meanings of the clone concept in the 1960s and 1970s, when the clone became a widespread metaphor that pointed to future biotechnologically driven possibilities to reshape the nature of human beings. In this regard, the debates of the 1970s are analyzed as a turning point: Whereas utopian and eugenic visions predominated the debates in the 1960s (when the human clone was seen as something which will occur in a distant future), the 1970s discussion focused on the advent of a biotechnological era and the human clone had became a reality.     

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.     

Formgeschichtliche und sprachliche beobachtungen zu psalm 57

Usually, Ps 57 is seen as formcritically mixed, but the exact interrelation between personal lament und thanksgiving song has not yet been established. Philological observations (especially, verbal forms and sentence structures) and formcritical deliberations make it clear, that 2-6 is a lament and 7(!)-12 a thanksgiving song. Therefore, 7 is interpreted as a retrospect of the trouble (7ab) and as a report of the deliverance (7cd). The tricola 8abc and 9abc have the same structure: a citation of a song (ab) followed by a speech-action (c). The structure of the psalm with its two stanzas and the closing refrains support this interpretation. By means of different poetic elements (refrain, the word "heaven" etc.) the two genres are interrelated, resulting in an organic whole.     

Die Entwicklung der Sozialgeschichte der modernen Mathematik und Naturwissenschaft und die Frage nach dem sozialen Raum zwischen Disziplin und Wissenschaftler

The use of the concept of social history of science is sketched in the Anglo‐American and the German discussions from the mid 1970s up to recent work. By presenting a ‘social map’ of a selected scientific community it is argued that between the categories of discipline and single scientist there exists a wide ‘social space’ of groups within which science is pursued. In adopting a milieu theoretic approach an ecology of science is proposed as a suitable extension of the social history of science.     

Historische Wissenschaftsforschung,heute. Überlegungen zu einer Geschichte der Wissensgesellschaft

Historical Science Studies Today. Thoughts about a History of the Knowledge Society. The article explores theoretical and historiographical approaches in the field of historical science studies, while focusing on the history of the knowledge society. It argues that a straightforward transfer of the concept of knowledge society into the past has to be pursued with care, favorably with an extraction of some analytical key concepts. This extraction is termed ‘decontextualization’ while a second approach, ‘contextualization’, is applied to the study of the knowledge society in its own time, namely the second half of the twentieth century. The latter approach needs to be combined with a history of science studies, especially a history of the concepts explaining and constituting the knowledge society itself. Furthermore, it is proposed to study the operative concepts of innovation and regulation in order to analyze the coupling processes of science, economy, technology, and government.

Zeitpfeile,Zeitfaltungen und Diskursanalyse: zu Kontinuitäten der Imaginationslehre

Time Lines, Folded Time, and Discourse Analysis: Continuities of Maternal Imagination. Focusing on a discourse‐oriented history of knowledge, this article deals with the relation between continuity and time. It will discuss concepts of linear and homogenous time and problematize a one‐sided focus on discontinuity and rupture in discourse analyses. After examining notions of continuity, discontinuity, and temporality in the work of Michel Foucault, I will ask how continuous elements can be theorized both as instruments and objects of research, without adopting a linear concept of time. Thus, Michel Serres' concept of folded time will be presented, because it implies a multiple, heterogenous and non‐linear temporality and entails both continuous and discontinuous entities. Thereby relations of power should be considered as factors influencing the shape of the folding. In this way, folded time can serve as a useful tool for discourse analysis, enabling to examine specific and local continuities that vary in different discursive formations. To give an example, I will briefly turn to the concept of women's imagination in pregnancy. According to most historical analyses, this concept declined in the middle of the 18^th century and persisted afterwards only as an outdated remainder in folk knowledge. Nevertheless, a closer examination reveals that knowledge on imagination was actively produced in medical advice literature and some scientific discourses until the first decades of the 20^th century. This demonstrates that an overemphasis both on rupture and on the timeline of academic medicine might conceal continuous elements and the folded time of specific knowledge formations.     

Reine und angewandte Chemie Die Entstehung einer neuen Wissenschaftskonzeption in der Chemie der Aufklärung

In its attempt to achieve acknowledgement and support as a true science and academic discipline eighteenth-century chemistry experienced that the traditional distinction between theory and practice, respectively between science and art, was an incriminating heritage and did not longer conform to the way chemists saw themselves. In order to substitute the former, socially judging classification into theoretical science and practical art, J. G. Wallerius from Uppsala coined the term pure and applied chemistry in 1751. The idea behind this new conception was that it ought to be chemistry's research aim and not the kind of work, be it manual or intellectual, which was to decide about its branches and their dignity. The change in orientation which took place during the eighteenth century, and which is symbolized by the new dichotomy “pure and applied”, led towards a revaluation of the utilitarian aspects of chemistry. Its historical roots reach back to a long and fruitful cooperation of, and interaction between chemistry and economy, which was reinforced by the Stahlian tradition in Germany and Scandinavia. Subsequently, it was its strong economic bias that helped chemistry to become institutionalized and accepted as an academic discipline distinct from the medico-pharmaceutical profession. The analysis of this change of attitudes, behaviour and institutional pattern suggests that, at least during the period of institutionalization of this particular discipline, social structures and the intrinsic scientific contents are so tightly interrelated, that any division into “internal”, cognitive developments (facts, theory and subject-matter) and “external” conditions (social context and stategies of institutionalization) would be artificial, since they both constitute the scientific community as a context of argumentation and action.     

Vernunft und Sprache — oder die Schwierigkeit,Kant auf Italienisch sprechen zu lassen

We can reach the exactness and univocity the scientific thougth aims at only by mastering the polysemy historically present in language. This appears even more difficult when we move from one polysemic system to another, as in translations into other languages. Thus, in Italy in the early XIXth century, the first attempts to translate Immanuel Kant's Critique of pure reason met great difficulties in understanding his new terms and led to misunderstanding and therefore rejecting his new philosophy.     

Etappen auf dem Weg zu einer Geschichte der Pflanzenzüchtung. Überlegungen aus Anlaß eines Buches von Thomas Wieland

Thomas Wieland's book is the first survey on the history of scientific plant breeding in Germany from 1889 to 1945. There are two mainlines of analysis: (1) The transformation of an agricultural practise of peasants into an academic discipline of scientists and (2) the importance of political arguments for this process of scientification. Most of the time Wieland's methods to present his thesis are exemplary: either as biographies or as breeding project histories. So he can write about a great diversity of aspects; but from his point of view – the discipline history as applied science – he cannot show the great importance of economic forces controlling plant breeding. This short article will not diminish the high value of Wieland's book. My aim is only to outline some desiderata for a history of plant breeding which is not yet written.
