Erfahrung und Vorurteil im naturwissenschaftlichen Denken Johannes Keplers

The change from ancient and medieval to modern natural science, called Wende (instead of ‘revolution’), must be associated with the work of Johannes Kepler and not that of Nicolaus Copernicus. Copernicus merely showed the way, introducing heliocentricity as the order of the planets. This Wende resulted from the synthesis of several disciplines formerly isolated from each other, namely mathematical (i.e. hypothetical) astronomy, new physics, mathematical harmony, astrology, new physical optics, and natural theology. Whereas Copernicus united mathematical astronomy and peripatetic (Aristotelian) physics, Kepler was first to see the necessity for providing a physical explanation and an ontological foundation to the heliocentric system. He was the first to consider and measure the movement of the planets in depth. The elements for his new physics Kepler obtained not from newly observed data, but from a harmonic archetypus of the regular polyhedra fitted in between excentric planetary spheres. On the basis of this archetypus (which he considered to be God's model in creating the universe) he accepted the new heliocentric planetary system as a physical reality. That is why astronomy, by way of taking into account stereometric quantities, is, in Kepler's eyes, a kind of divine worship. Later, the best empirical data had also to be taken into consideration as a means of proving this a priori archetypus (Vorurteil, preconception). The result was, on the one hand, a universal natural science able to explain natural processes in grater abundance than ever before or since in the history of science. Although accepted only in parts, it resulted in founding a new natural science with adherent mathematical and empirical methods. It also led Kepler to establish, step by step, the elliptical path of the planets, thereby overcoming, for the first time, the two axioms of ancient astronomy, requiring uniform and circular planetary motion. It has been shown that this Keplerian Wende was possible only within the Historischen Erfahrungsraum (‘historical field of experience’) of Renaissance Humanism (cf. this Journal 9/1986, p. 201), which came about itself as the result of reactivating the scientific and philosophical thinking of the ancient Greeks and was accomplished by three steps (phases) relating to the revival of (1) original ancient writings, (2) the ancient knowledge of natural facts and data, and (3) the ancient scientific and philosophical ideas and mentalities (Drei-Phasen-Modell).     

自我的觉醒:彼特拉克与现代性

自布克哈特在《意大利文艺复兴时期的文化》中首次提出彼特拉克是"第一个现代人"后,引发学术界关于彼特拉克是"现代人"抑或中世纪人的激烈争论。身处中世纪与文艺复兴新旧交替以及"现代人"与旧有传统矛盾的历史时期,作为文艺复兴之父的彼特拉克首当其冲地经历了这场巨变。在经历青年、中年和老年的三场觉醒后,彼特拉克意识到自己需要摆脱过去与未来之纠缠,在新旧的断裂带中寻找突破时间限制的夹缝,让自己的作品在时间的洪流中保持永恒的鲜活。     

Zum Verhältnis von Religion und Zoologie im 17. Jahrhundert (William Harvey,Nathaniel Highmore,Jan Swammerdam)

Jan Swammerdam was one of the first scientists to do biological research on the basis of physico-theology. He was a very religious man and thought that by studying the secrets of nature he could best serve the Almighty God. He saw his life's work in demostrating the importance of God in the world of the smallest animals. The most important works of Swammerdam refer to the world of the insects and other lower animals, which he called the ?legions of the God of Israel”?, through which God tells mankind to recognize their sins, to desist from them and to honour him with greater humility. ?The miracles of nature”? he said ?are an open bible, which everywhere points to God as its eternal origin.”? This is one of the reasons for the title of the work Biblia naturae. It was Swammerdam's declared aim to demonstrate that the insects were no less perfect than the higher animals. Therefore, he tried to refute all three arguments used by his contemporaries to show up the difference between the higher animals and the insects: 1. insects were believed to have no inner anatomy; 2. they were thought to originate by spontanous generation; 3. development occurred through ?metamorphosis”?. Swammerdam succeeded in refuting all three arguments by exact studies of the nature and development of the insects. Most important for him was his aim to demonstrate that even the structure and the development of the smallest of animals demonstrate that they could only be made by God himself. Science as God's worship must be strictly objective, he said, because only than could one understand the laws of nature and in this way the real nature of God himself.     

Die Verlegung der Berliner Sternwarte nach Babelsberg — ein konservativer Neubeginn

In 1913 the Berlin Observatory was moved from the center of the city to Babelsberg on the outskirts of Berlin, now part of Potsdam. The new observatory was considerably larger in size and with respect to its staff, and it had got a completely new equipment. At that time it was the most modern astronomical observatory in Germany and possibly even in Europe. However, the scientific results achieved afterward were not comparable to that of other institutions, especially in the USA. A main reason was the conservative concept for the observatory, drawn up by Wilhelm Foerster and his colleagues, and restricting the work to classical fields of astronomy. Foerster's successor Hermann Struve tried to follow rather strictly this concept as well as the traditions of his family of astronomers. This led to conflicts with his collaborators Eugen Goldstein, Erwin Finlay Freundlich and Paul Guthnick, who were interested rather in astrophysics than in the classical problems.     

Tradition and Reform: Aristotle’s Response to Modern Alternatives

Abstract

This essay is an attempt to articulate an Aristotelian alternative to two prominent contemporary ways of understanding human freedom and dependence on the past, and to the implications these understandings have for political life. While a liberal tendency, following Machiavelli’s emphasis on new modes and orders, understands political life to begin with breaking from the past, the more conservative camp in modern thought, following Burke in his emphasis on tradition, understands political life to begin with laws and customs inherited from the past. Aristotle’s teaching in his Nicomachean Ethics on the freedom and responsibility that make human beginnings possible points us, I propose, to a better understanding of political founding than either modern alternative. In the Politics, he connects the city to natural beginnings in the family but also calls the first who founded a city one “responsible for the greatest of goods” (Pol. 1253a31-32). And in the Ethics, he offers his own founding of a way of inquiring about politics, which engages with his predecessors, as a model for politics itself. In this way, Aristotle offers us a deeper understanding of political founding and change, even presenting his own philosophic inquiry in the Ethics as its ground and model.     

Physiological optics, cognition and emotion: a novel look at the early work of Wilhelm Wundt

The German physiologist Wilhelm Wundt, who later founded experimental psychology, arguably developed the first modern scientific conception of emotion. In the first edition of Vorlesungen über die Menschen- und Thierseele (Lectures on human and animal psychology), which was published in 1863, Wundt tried to establish that emotions were essential parts of rational thought. In fact, he considered them unconscious steps of decision-making that were implied in all processes of conscious thought. His early work deserves attention not only because it is the attempt to conceptualize cognition and emotion strictly from a neural point of view but also because it represents the very foundation of the debate about the nature of emotion that revolved around William James' theory of emotion during the 1890s. However, this aspect of his work is little known because scholars who have analyzed Wundt's work focused on his late career. Furthermore, historical analysis interpreted Wundt's work within a philosophical framework, rather than placing it in the context of German medical and physiological research in which it belongs. In addition, Wundt's early works are hardly available to an English speaking audience because they were never translated.

Abstract

Flinders Petrie was one of the earliest excavators to recognise that all archaeological material had research potential, and pursued a whole range of artefact types as the key to understanding past cultures. But what impact did the way in which he excavated have on the rate at which objects were discovered, and the condition in which they were found? And how important was it to him that the objects he acquired were closely linked to the physical and chronological landscape of his sites? This article looks at Petrie's field practices to try and answer some of these questions, with particular attention being paid to the relationship between Petrie and his workforce, his object collection policies, and some of the failings experienced in recording object provenance. These issues are critical to those who wish to make use of these objects to answer current questions about the ancient Near East—because it is only by understanding the way in which this material was recovered that we can begin to judge how it should be used in the present day.     

Über die Aufhänge- und Anzeigevorrichtung der ägyptischen Waage der Pharaonenzeit

A number of different and partly contradictory interpretations about the suspension and the indicator system of the ancient Egyptian balance has been given so far. In this article previous explanations of these devices are presented and critically considered; at the same time the balance of the Egyptians is included in the complete evolution of this instrument. Based on original Egyptian colour drawings on papyrus taken from the Book of the Death and considering weighing techniques, it is stated that all interpretations given so far are not capable of providing a satisfactory explanation of the function of these devices. The interpretation given already in 1888 by Sir Flinders Petrie comes closest to the real function of the indicator system: According to his assumption the device consisted of a solid pointer attached to the beam, in relation to which a plumbline was observed after the oscillations had stopped. This interpretation, however, has to be varied or to be complemented by taking into consideration the special drawing technique of the ancient Egyptians: Processes were drawn in a reproduction technique which consisted in the simultaneous combination of a top view and a side view. A new hypotheses about the function of the suspension and the indicator system of the ancient Egyptian balance is presented, which has the advantage of agreeing completely with the Egyptian drawing technique and which, in addition, ensures optimum precision of the weighing procedure.     

“Man ist nicht umsonst Philologe gewesen …”. Zur Bildungskritik Friedrich Nietzsches

Up to now, Nietzsche's ideas on culture and education have been figured out mainly from his early writings. Accordingly, most authors ascribed to him a negative, at least reluctant attitude towards science and studies. On the contrary, in this paper it is argued that Nietzsche, from time to time, reconsidered and changed his thoughts and that he rather favoured science and studies. To be more specific, four periods may be distinguished. As a boy Nietzsche strived for a religious education. But while a pupil at Schulpforte he changed his mind and strongly pleaded for a secular, historically dominated erudition. Again during the seventies in Basle, he pointed out the dangers of a one-sided historism, but in his later years he returned to his high esteem of history. — Basically Nietzsche was interested in a hermeneutical theory combining artistic vision and scholarly work.     

L’articulation du scepticisme religieux et du scepticisme profane dans l’Histoire du scepticisme d’Érasme à Spinoza, de Richard H. Popkin

The History of scepticism from Erasmus to Spinoza by Richard H. Popkin is not just an account of various sceptical doctrines of the 16th and 17th centuries: a thread gives the whole a coherence. In fact, a general conception of modern philosophy underlies his analyses. According to Popkin, philosophy, from the Renaissance to the Englightenment, was faced with the difficulty of overcoming the sceptical crisis which was born in the context of a religious quarrel and which quickly spread to all other intellectual fields. Thus, Popkins gives an original interpretation of modernity, an interpretation that can be questionned nevertheless in so far as he does not make a clear enough distinction between modern and ancient scepticism and does not take into account the specificity of fideism.     

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.     

La théorie des éléments de Christophorus Clavius et l'idée du globe terraqué

Christophorus Clavius' Theory of the Elements and the Idea of the Terraqueous Globe. The need to reconcile Aristotle's theory of elementary spheres with the evidence of earth above sea level – the so‐called ‘terra firma’ – induced an important conceptual shift. As a consequence anti‐Aristotelian arguments were brought to the fore in order to be incorporated into the very same Aristotelian tradition. The German Jesuit Christophorus Clavius played a momentous role in this process. He introduced the idea of the terraqueous globe into the Scholastic cosmology, modifying the logical frame of Aristotelian physics. The present work analyses Clavius' theory as well as the procedures he considers to reach his purpose. He used a combinatorial approach to study the relations occurring between the four elements – earth, water, air and fire – and analysed their relations from a physical perspective, proposing a possible structure of the sublunary world.     

CHARTING THE “TRANSITIONAL PERIOD”: THE EMERGENCE OF MODERN TIME IN THE NINETEENTH CENTURY

This paper seeks to chart a concept of historical experience that French Romantic writers first developed to describe their own relationship to historical time: the notion of the “transitional period.” At first, the term related strictly to the evolving periodic conception of history, one that required breaks, spaces, or zones of indeterminacy to bracket off periods imagined as organic wholes. These transitions, necessary devices in the new grammar of history, also began to attract interest on their own, conceived either as chaotic but creative times of transformation, or, more often, as slack periods of decadence that possessed no proper style but exhibited hybrid traits. Their real interest, however, lies in their reflexive application to the nineteenth century itself, by writers and historians such as Alfred de Musset, Chateaubriand, Michelet, and Renan, who in their effort to define their own period envisioned the “transitional period” as a passage between more coherent and stable historical formations. This prospective self‐definition of the “age of history” from a future standpoint is very revealing; it shows not just the tension between its organic way of apprehending the past and its own self‐perception, but it also opens a window on a new and paradoxical experience of time, one in which change is ceaseless and an end in itself. The paper also presents a critique of the way the term “modernity” has functioned, from Baudelaire's initial use to the present, to occlude the experience of transition that the Romantics highlighted. By imposing on the nineteenth‐century sense of the transitory a heroic period designation, the term “modernity” denies precisely the reality it describes, and sublimates a widespread temporal malaise into its contrary. The paper concludes that the peculiarly “modern” mania for naming one's period is a function of transitional time, and that the concept coined by the Romantics still governs our contemporary experience.     

Nur „Zweite Wahl”︁ oder Die Berufung Adolf Butenandts zum Direktor des KWI für Biochemie

The remarkable career of the nobel laureate Adolf Butenandt in Germany before 1945 and especially after the second world war is well known. But in recent years several publications have questioned his personal behaviour in the Third Reich. But all these articles interpreted Butenandts career and his attitude from our knowledge today about Nazi Germany. From archival sources this article will view on the situation in the 1930s and will show that Butenandt was originally not the first choice of the government for the position of director at the Kaiser‐Wilhelm‐Institute for Biochemistry. Finally it is shown, that Butenandt did knew what was going on behind the scenes, because through his close connections with officers of the Rockefeller Foundation he got several information on the selection.     

THE TEETH OF TIME: PIERRE HADOT ON MEANING AND MISUNDERSTANDING IN THE HISTORY OF IDEAS1

The French philosopher and intellectual historian Pierre Hadot (1922–2010) is known primarily for his conception of philosophy as spiritual exercise, which was an essential reference for the later Foucault. An aspect of his work that has received less attention is a set of methodological reflections on intellectual history and on the relationship between philosophy and history. Hadot was trained initially as a philosopher and was interested in existentialism as well as in the convergence between philosophy and poetry. Yet he chose to become a historian of philosophy and produced extensive philological work on neo‐Platonism and ancient philosophy in general. He found a philosophical rationale for this shift in his encounter with Wittgenstein's philosophy in the mid‐1950s (Hadot was one of Wittgenstein's earliest French readers and interpreters). For Hadot, ancient philosophy must be understood as a series of language games, and each language game must be situated within the concrete conditions in which it happened. The reference to Wittgenstein therefore supports a strongly contextualist and historicist stance. It also supports its exact opposite: presentist appropriations of ancient texts are entirely legitimate, and they are the only way ancient philosophy can be existentially meaningful to us. Hadot addresses the contradiction by embracing it fully and claiming that his own practice aims at a coincidence of opposites (a concept borrowed from the Heraclitean tradition). For Hadot the fullest and truest way of doing philosophy is to be a philosopher and a historian at the same time.     

太平天国早期萧朝贵与杨秀清关系考辨

“天兄”代言人萧朝贵与“天父”代言人杨秀清之间并非纯粹的同盟、挚友,两人在合作共事的背后,隐藏着鲜为人知的矛盾。在太平天国的孕育期,“天兄”曾通过揽权、培植私党、代理首辅,试图创造超越“天父”权威的神话。在金田团营的关键时刻,萧朝贵还利用直接命令、诋毁中伤、孤立压制等手段欲使病重的杨秀清脱离上帝会的权力核心,实现自己的政治抱负。但“天兄”（萧朝贵）与“天父”（杨秀清）之间的关系也不能简单地视为对手、仇敌,两者微妙的政治、宗教关系以及太平天国生存的主客观环境,都决定了萧朝贵的“夺权”仅是一股无法逾越地表的政治暗潮。
