Eine handgreifliche Geschichtslüge. Wie Martin Luther zum Gegner des copernicanischen Weltsystems gemacht wurde.

Martin Luther has been severely criticized for an offhand remark about Copernicus. In the most frequently cited version of this statement, Luther is alledged to have branded Copernicus as a fool who will turn the whole science of astronomy upside down. This disparaging judgment on Luther prevails in many publications by respected historians of science of the 20th century, although since the early thirties, it has been convincingly demonstrated that the famous citation from Luther's table talk is next to worthless as an historical source, that Luther never referred to Copernicus or to the heliocentric world system in all of his voluminous writings, and that there is no indication that Luther ever suppressed the Copernican viewpoint. His attitude towards Copernicus was indifference or ignorance, but not hostility. In this paper, it is shown that the story of Luther's anti‐Copernicanism emerged in the second half of the 19th century. It was invented by Franz Beckmann and Franz Hipler, two Prussian Catholic historians who were engaged in the conflict between the German government under Bismarck and the Catholic Church (Kulturkampf), and it was disseminated by influential German and American historians like Leopold Prowe, Ernst Zinner, and Andrew D. White. In the second half of the 20th century, many historians of science relied on the authority of these authors, rather than studying the sources or the secondary literature in which it has been proved that Luther's anti‐Copernicanism is an outright falsification of history.     

Die Mathematisierung der Naturwissenschaften vor dem Hinter-grund der Bildungsvorstellungen des 19. Jahrhunderts

Both, astronomy in the first half of the 19th century and physics in the second half of the 19th century functioned as models and paradigms for the other sciences. The paradigmatic character of a theoretical, mathematical astronomy was due mainly to its capability to predict future events. According to the influence of the Romantische Naturphilosophie the mathematization of physics in Germany took place belatedly compared to France. A modified Newtonian research program with its mathematical implications was adopted by German physicists only after the establishment of the principle of energy conservation. German physicists of the late 19th century claimed over and above the results of physicists the successes of German technology for physics and interpreted these achievements as “cultural” achievements. They combined this claim with a request for a better representation of physics in the curricula of secondary schools so as to be comparable to that of mathematics. The resistance of the most prestigious secondary schools, the Humanistische Gymnasien, against this request meant that the concept of Bildung as propagated by physicists was not accepted generally in Germany.     

Universitäre Freiräume im Spätmittelalter als Wegbereiter neuzeitlicher Naturwissenschaft

University freedom in late Middle Ages as a way to modern natural history: The question regarding the relation between faith and natural history in late Middle Ages was answered in different ways. In the way of thinking shaped by Augustinian philosophy there existed, in early Middle Ages, a close connection between natural science and religious belief. In the second half of the 13th century attempts were made at dividing natural science from supernatural sphere. In late Middle Ages it was endeavoured not only to liberate natural history from the domination of theology and metaphysics but also to achieve the autonomous treatment of nature. These endeavours became fully accomplished by Nicolaus Copernicus.     

Romantische Naturkunde - Die Doppelsinnigkeit der Naturbildung des Bernhard Heinrich Blasche (1766-1832)

Naturbildung, written by B. H. Blasche in 1815, seems a typical philanthropic study about science education private organized. But it also demonstrates romantic philosophy influences, which led at least from describing natural history to biology. There was no success in Blasche's reformatory efforts: first reason because the idea of private education-institution was out of discussion. Second reason was, on the way to stateorganized schoolsystem in Germany classic philology dominated and repressed deeply science education.     

Körpergefühl und Raumvorstellung: Leonardo und Descartes

“Experience and the conception of the world in science in transition to modern times” is the general subject. There are two different points to be made clear, i.e. 1. That the conception of the world had to be made imaginable by art before it could be taken over by science. The central perspective dates back to about three centuries before the time Descartes developed the co-ordinate system. 2. Furthermore it should be taken into account that it was first of all due to the lead of the painters (especially in the Italy of the Quattrocento’) that the possibility of making experiences had changed. In a space opened by a perspective view and seemingly thus appearing as measurable even the painted figures acquire a new reality. Due to his anatomic studies Leonardo could treat the natural movement of the figures shown in his paintings. It was the artists who first of all investigated optics and anatomy before relations could be measured with the aid of scientific methods ami before quantities — instead of qualities — could become the base of unbiased science, as called for by Galilei in 1623.     

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.     

Das Werden des Kosmos Von der Erfahrung der zeitlichen Dimension astronomischer Objekte im 18. Jahrhundert

The Permanent ‘Becoming’ of the Cosmos: On Experiencing the Time Dimension of Astronomical Entities in the 18th Century. - This paper deals with two of the initial stages through which the dimension of time, in the sense of an irreversible development, found its way into astronomical-cosmological thinking. The one resulted from the first consequental application of Newtonian principles and laws to cosmic entities outside of our solar system found in the General Natural History or Theory of the Heavens of Immanuel Kant (1755): Endeavoring to explain through natural causes first the peculiarities of the solar system, no longer naturally explainable through the celestial mechanics of Isaac Newton (such as the common orbital plane and rotational direction of all the members of the solar system and the distribution of the masses) - which, however, had been deducible in Johannes Keplers Weltharmonik -, and endeavoring secondly to explain above all the beginning of the inertial movement of all discrete heavenly bodies - which, however, could have been derived from René Descartes's vortex theory - without using arbitrary acts of God as Newton had done, Kant had to introduce an initial state in which matter in the form of atoms was equally and almost homogeneously distributed over the whole space (similar to the permanent state in Descartes's theory). Thereupon, according to Kant, the initial movements of the slowly growing masses resulted from the effect of gravitational forces. The parameters within the solar system which had to be explained, could then be easily deduced from the process of mass concentration at different points and from the resulting vortex movements. - The other initial stage is found in the classification of ‘nebulae’ by William Herschel who introduced the historical time factor, in the above-mentioned sense, as a principle of order in addition to the outward shape, which had become common for all the different elements in natural history during the second half of the 18th century. Thereupon the different shapes of the nebulae could be interpreted as stages of development from the primordial nebular state to multiple or single stars. (Herschel had not yet considered them to be accumulations of stars for lack of a suitable telescope.) Both initial stages, which arose out of the thinking of the second half of the 18th century, were still premature for astronomy and cosmology; they have only been taken up again since the end of the 19th century as a result of the emergence of astrophysics, which provided the empirical data for the earlier speculations and conclusions from analogy.     

Wissenschaft im Gehäuse: Vom Nutzen und Nachteil institutionengeschichtlicher Perspektiven

Research is realized in social and cultural context, it is established in institutions, as far as different forms and conditions of practice are concerned. In this article some German examples demonstrate how flexible and varied the institutions of research can be during the course of history of science. The first part deals with historically grown, yet chronologically overlapping institutions of research: beginning with the lonely scholar, going on to hierarchally organized big science and ending up with virtual institutions. In the second part, at the intersection of political‐social administration and styles of scientific thought terms like German Realpolitik, science in context, and science policy are discussed within the modernization process.     

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.     

Jesuiten zwischen Religion und Wissenschaft

Natural sciences and natural philosophy of the Jesuits are based on theology. At least the concept of God is an integral part of their theoretical structure. Examples are taken from Rudjer Boskovic, Honoré Fabri and Nicolaus Cabeus. In fact, the Jesuits, e.g. Theophil Raynaud, dealt with natural theology as the spiritual foundation of knowledge independent of revelation. But natural theology, as in Raimundus Sabundus, has an anthropocentric and hence moral dimension: it links knowledge with religion. ‘Ignatius of Loyola influenced decisively the Jesuits’ concept of science and its relationship to religion through his Spiritual Exercises in which meditation and religious practice are developed into a technique and a scientific approach to faith.     

Die Französische Revolution im Spiegelbild. Die Reaktion der deutschen Ärzte auf die Revolution und das Revolutionieren

The German physicans and medical scientists reacted to the French Revolution in several ways, if you judge only from the medical literature:

• 1 At the beginning of the French Revolution, the scientist answered with still silence, whereas the young intellectual generation was filled with enthusiasm. But after the battle of Valmy (1792) this enthusiasm vanished and they resigned to execute an equal revolution in Germany.
• 2 When, in the middle of the 1790s, scientists gave commentaries on revolutionary acts, they despised the revolution itself. This could only destroy the old – and even better – order. They argued that you can have recourse to science to avoid the political and socially deranged situation.
• 3 This rejection against the political revolution was combined with a rejection against the influences of natural philosophy on medicine. Schelling's philosophy plays the role as an scientific revolution with all negative aspects like the political one. In this sense, the science in the old scientific manner has to be an accepted refuge.
• 4 But in this retreat they developed ideas of German national science to conteract on the French influences. The consciousness of nationalism was supported by the scientists of romantic movements.
• 5 The following degree is characterized by a mental leap. Now, they argued, it will never be necessary to revolutionize the medicine: in science all the ideals of French Revolution are realized – freedom, equality and fraternity.
• 6 Consequently, only in a formal sense did they respond to the French Revolution and so they avoided recognizing, that science is influenced politically and also science itself exercises on in a political way.

     

“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.     

Die Entdeckung des Unbewußten um 1900: Wissenschaftshistorische Anmerkungen zu Sigmund Freud

The Discovery of the Unconscious by Henri F. Ellenberger has become a common topic in the historiography of (dynamic) psychiatry. But many users of this term have still the opinion that Sigmund Freud was the unique discoverer. In reality there was a scientific context at the fin de siècle, which corresponded intensively with Freud's original concepts and formed their implications (e.g. Darwinism, Neurophysiology). Besides well-documented synchronic analogies Freud implanted diachronic traditions within his psychoanalytic theory. Especially, his main work The Interpretation of Dreams implies Greek mythology as well as natural philosophy of romanticism. Freuds special concepts like ‘transfer’ and ‘resistance’ have to be analysed as historical metaphors.     

Naturwissenschaft und Religion in den Niederlanden um 1600

Dutch science flourished in the late sixteenth and in the seventeenth century thanks to the immigration of cartographers, botanists, mathematicians, astronomers and the like from the Southern Netherlands after the Spanish army had captured the city of Antwerp in 1585, and thanks to the religious and the socio-economic situation of the country. A strong impulse for practical scientific activities started from the Reformation, mainly thanks to its anti-traditional attitude, which had an anti-rationalistic tendency. Therefore, in the Northern Netherlands there was no ‘warfare’ between science and religion and the biblical arguments leading to Galileo's condemnation were not used. Although the growth of the exact sciences and of technology in the late sixteenth and the seventeenth centuries in Protestant cirles may be partly attributed to the expansion of trade, industry, navigation and so on, this does not explain why there was also at the same time a great interest in subjects as botany and zoology, which had no immediate economic utility. There were discussions about Copernicanism and Cartesianism. So a number of astronomers and theologians rejected the earth's movement on scientific and religious grounds, but there were also those who did not reject the Copernican system on biblical grounds. In the seventeenth century there was much discussion between science and religion in the Northern Netherlands, but that discussion was not followed by censure by the Church of the State. In the Republic there was a large amount of intellectual freedom in the study of the natural sciences, thanks to practical and ideological considerations. In the eighteenth century the seventheenth century tension between science and religion changed into a physicotheological natural science. It was believed that investigations into the workings of nature should lead to a better understanding of its Creator. So Bernard Nieuwentijt in his well-known book: The right use of-world views for the conviction of atheists and unbelievers (1715) intended to prove the existence of God on the basis of teleological arguments.     

Das erste Jahrhundert deutschsprachiger meteorologischer Lehrbücher

Sequences of text books published during a longer time span offer the opportunity to describe the development and forming of scientific disciplines. Here, the forming of meteorology as a separate discipline is analysed from German textbooks published between 1803 and 1901. This first century of meteorological textbooks can be divided into three phases: (1) a phase of the final definition of meteorology as a discipline within physics (1800–1840), (2) a phase which sees meteorology as an established part of physics (1839–1870), and (3) a phase of further developments within meteorology on the basis of the theoretical equations of hydrodynamics (1875–1901) during which meteorology finally forms as a separate discipline. In phase 1, meteorological textbooks were written by physicists, mathematicians, and other natural scientists. In phase 2, the textbooks were based nearly completely on Pouillet's textbook on physics and meteorology, and finally in phase 3, meteorologoical textbooks were written by meteorologists. The Germanlanguage meteorological textbooks from 1803 to 1901 are listed in Table 1. These books document the shaking off of old views in the beginning of the 19^th century, the establishment of meteorology as a separate discipline in natural sciences in the middle of that century, and the beginning of a specialisation within meteorology at the end of that century.     

Aspekte angewandter Wissenschaften in Moscheen und Klöstern (Teil I)

Only recently have the abundant sources relating to the application of astronomy to the needs of religious ritual in medieval Islam been studied, and it is now possible to write a new chapter in the history of Islamic astronomy. Simple techniques were advocated by the scholars of the religious law, highly sophisticated and complicated solutions were proposed by the Muslim scientists. It is not without interest to compare and contrast this activity, which lasted over a millennium, with that of the monks of the Christian Middle Ages. The history of the latter has not yet been written, and cannot be written from textual sources alone, as is clearly shown by some of the astronomical instruments presented here. The present essay, in which both the Islamic and Christian traditions are discussed side by side for the first time, is very much a preliminary venture, primarily intended to point to the inherent interest of the available materials for the history of science as well as for several other disciplines.     

Huygens’ stargazing scientists: the idea of science in Cosmotheoros

This paper deals with the book Cosmotheoros (1698), in which Christiaan Huygens presented his concept of a universe made up of many inhabited planets. Recent interpreters of this work have focused especially on cosmological issues presented in the book. Cosmotheoros, however, comprises also various philosophical ideas. In this paper I want to focus on the concept contemplator coeli – stargazer. The stargazer was the embodiment of the philosophical ideal of the contemplative way of life that appeared in classical philosophy and astronomy. I want to argue that Huygens followed on from the idea of the stargazer and used it in his hypothetical construction of extra-terrestrial life. At the same time, however, he altered this idea in such a way that it corresponded better to the ideals of science at the end of the seventeenth century. In Huygens’ concept, the noble contemplator coeli turned into the modern scientist who works with other scientists on the advancement of mankind’s knowledge of nature. Huygens’ stargazers are a good example of how strikingly the basic assumptions of knowledge of nature in the early modern period changed with regard to classical antiquity.     

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 Astrologie der Antike

This survey of classical astrology is in three parts: a) a summary of its rich and eventful history from the Babylonians to the Renaissance; b) the methods of calculation which remained the same throughout the period, based on the planets, the zodiac and the “twelve houses”; c) an analysis of astrological thought, which is quite different from any modern approach; providing a rigid interpretation of the universe, it granted confort and security. It presents a curious combination of religion and science: the physics is the one forwarded by the stoïcs, with an equal balance of the four elements, and the microcosmic economy within the soul representing the macrocosmic one; but such a determinism is in contradiction with the Stoics' sense of responsability which presupposes free will.
