Die Centrosophia des Athanasius Kircher SJ: Geometrisches Paradigma und geozentrisches Interesse

The main subject of the paper is to give an example of what could be called, in the history of philosophy and science, reinforcement of traditional topics or paradigms of explanation in order to give explanatory support to or to coooborate the defence of old or the solution of new problems. In the 17th century nearly all positions in the natural science are dependent from theological and philosophical (metaphysical) presuppositions, especially all positions which belong to types of the scientia universalis (Yves de Paris, S. Izquierdo, A. Kircher). To defend the finiteness of the world and the geocentric position of the earth, the Jesuit A. Kircher (1602–1680) returns to an old topic of cosmological speculation, to the geometria speculativa, in order to demonstrate the absolute perfect and finite structure of the world as an analogon of the absolute perfect and finite structure of the cercle or, better, the sphere (globe). He shows this in his Iter exstaticum (Rome 1656) and in his Mundus subterraneus (Amsterdam 1665). The paper discusses only a central part of the Mundus subterraneus titled ‘Centrosophia’: here we find all typical arguments for the phenomenon of reinforcement of old topics and paradigms. God is the center or the non-dimensional point (punctum) of the cosmic sphere (which is the sphere of all being) and he is in consequence the principle of all geometrical (ontological) parts of this figure. Kircher transmits the evidence of the perfect geometric relation between center and circumference modo analogico to the relation God (creator) and world. Together with this well known and often used analogy he develops a new theory: the theory of the dignity of the subterranean parts of the earth and the earth as earth, as the unic and ideologically exclusive place in all reality that gives mankind the fundament to develop its own implications. The high estimation of the earth sets free an unprejudiced view of what the subterranean area really is: Kircher thinks here in organologic categories — the subterranean world is an analogon of the world as such and this world is a great animal. Kircher develops in the limits of his traditional geocentric position an new non-traditional theory of the inner side of the world.     

„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.     

Raumvorstellungen und Erkenntnismodelle im 18. Jahrhundert

Since the late 17^th century, two physical concepts of space exist. Isaac Newton's theory of an immovable ‘absolute space’ made it possible to explain motion and force by the quality of material elements. Less influential was Gottfried Wilhelm Leibniz's concept of space as an ‘order of coexistence’, which focuses, contrary to Newton, on the relationship between material bodies. The author argues that both concepts not only concern physical notions, but also include general models to explain cause, effect and relation. In an analogy to Newton's ‘absolute space’, theories of natural law employ the state of nature to explain society according to the anthropological quality of human beings. Leibniz's concept, in contrast, is used to elaborate theories of complex dynamic interactions and relationships. This essay attempts to illustrate the application of Leibniz's concept with examples of 18^th century natural history, demography, economic theory and Charles Bonnet's natural law.     

Unterscheidung und Synthese: Rezeptionsformen akustischer Forschung in der Musikliteratur des 19. Jahrhunderts

Differentiation and synthesis. Forms of reception of acoustical research in the musical literature of the nineteenth century. In the nineteenth century, both musical scholars and natural scientists discussed the relevance of acoustical research for the theory and practice of music. Whereas some musical theorists and acousticians plead together for an acoustical foundation of musical theory, other scholars questioned the significance of physical and physiological knowledge for a deeper understanding of music. Based on an analysis of musical journals, popular scientific writings, theoretical treatises and musical dictionaries this article demonstrates how musical scholars and natural scientists argued about the question which discipline should have the final say about musical concepts and terminologies. To merge both heterogeneous spheres – music and acoustics – or to carefully distinguish between them – these two positions shaped the dispute over the relationship between music and natural sciences in the nineteenth century.     

Der Natur‐Begriff des 17. Jahrhunderts und zwei seiner Inter‐pretamente: „res extensa”︁ und „intima rerum”︁

This article aims to show the general and broad use of the concept of nature in the philosophical discourse of the 17th century ‐ and in this context it is obvious that this discourse includes both philosophy and theology. I will discuss two opposite views concerning its fundamental understanding of nature, yet will not go into elaborating differences concerning such particular concepts as, for example, space, void or motion. These views and the theoretical positions from which they emerged will here be called res extensa and intima rerum ‐ this is done in order to clarify the basic opposition: there is no interior in pure extension and there is no extension at all in that what is called the interior. My aim is to show that these two views are, in fact, not quite as incompatible and contradictory as it easily may seem at first glance. Although I will for heuristic purposes introduce the two concepts res extensa and intima rerum as complete opposites and in a wholly contrary manner, ist should become clear that there exist both influences and interactions between these two notions. Theorists introduced here as advocates of the intima rerum‐position, can, for example, be seen as having been influenced by the mechanistic, or res extensa‐position, mainly through the formally and methodologically attractive geometric and mathematical argumentation. Likewise theorists advocating a mechanistic position can be said at some points to have been led by a substantial necessity concerning the contect of their argumentation to take recourse to the concept of intima rerum, at least partly or in a modified manner.     

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.
