Natur-Wissenschaft und Gotteserkenntnis: Das jüdische Modell

The thesis proposed here is that in Judaism creation is seen as a unique act of God at a specific point in time. In medieval philosophy the act of creation is interpreted as natural science, which concerns itself only with products of divine creation. This is contrasted with theology, which is concerned not with creation but with God. Francis Bacon takes this model from Moses Maimonides for his work Nova Atlantis. Natural science replaces theological studies for Bacon.     

Schweretheorie und Weltbild des Nikolaus von Kues: Zu ihrer vermeintlichen Modernität

Regarding his world view and his heaviness theory Nicolaus Cusanus is imputed to having used (at least to some extent) forebodings and anticipations of modern conceptions. In the dialog Idiota de staticis experimentis he imputed the quantitative points of view of modern physics programmatically. In contrast with this, this article will show that the quantitative point of view is proposed for an inapt object at least. Cusanus based his reflections on one hand on the Aristotelic theories of elements and their heaviness with ‘positive’ and ‘negative’ weight (only thus, assumed inconsistencies can be explained), on the other hand he wants to determine the essential, qualitative properties of the forma, while only their complete abstraction by reduction on the mass without properties should result in an object for comparative weighings — lately in different ways by René Descartes and Isaac Newton. The putative modernness of cusanian conceptions compared with Aristotle are based on the tradition of platonian and stoic modifications which sooner were compatible with christian ideas.     

Geographischer und astrologischer Zonenbegriff in der Antike

The five (or seven) zones are treated during Greek‐Roman antiquity in geography and theoretical astrology as well. Although there is no use of them in astrological prognostication, they occur in the ascending scale of the twelve planetary houses. The common planetary order (moon ‐ Mercury ‐Venus ‐ sun ‐ Mars ‐ Jupiter ‐ Saturn) owes its widespread success primarily to its symmetry on both sides of the central sun, but the twofold vertical mesotes‐pattern in the heaven seems to be invented according to the horizontal symmetry of the five geographical zones surrounding the terrestrial equator.     

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.     

Der Ort des rhetorischen Wissens Kunst und Natur bei Isokrates

This paper poses the question of the place of rhetoric as a discipline. It addresses the topical demand that nature, art, and exercise have to be combined by way of an analysis of Isocrates' Against the Sophists. Its thesis is that the call for a “combination” of art and nature solves the disciplinary problems of rhetoric, even though such a synthesis is in fact inconceivable. Rhetoric is not a science, and does not have access to a methodical correlation of rhetorical strategies and their effects upon the audience. Isocrates' criticism of those rhetoricians who assume that their art could be taught in much the same way as the art of writing is of paramount importance here. The case of Isocrates is instructive because it shows how rhetorical success depends on re-designing the institutional structure of rhetoric and on the capacity to cope with its lack of methodical knowledge. As a result of its para-scientific nature, rhetoric refers to various models and metaphors to present itself as a discipline. Of these the orator perfectus, the orator imperfectus, and the sophist model of the art of writing as criticized by Isocrates are discussed. This paper attempts a rhetorical reading of the discourse of rhetoric by exploring the implications of these metaphors. At the same time it argues for a history of science which does not shrink away from an analysis of such para-sciences as rhetoric. It is precisely the lacking scientificity of rhetoric as a discipline which warrants increased attention from the point of view of the history of science.     

Genauigkeit — was ist das? Wandel des Konzeptes zwischen Antike und Neuzeit

Since the concept of reality has been dominated by the methods of modern natural science, the criteria of precision have been restricted to exact measurement, i.e. quantification required by experimental science and technology. In premodern times, however, the paradigm according to which reality was conceived, designed a universal correspondence of substances and processes by the construction of analogies. These had a kind of ‘semantical’ precision, though different from mathematical, nevertheless in the end leading to mathematical proportionality. This premodern type of precision is explained by examples from Anaximenes and Plato.     

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.     

Frühe Fälle der "Verwendung" von Analogien in der altgriechischen Medizin

Analogy in ancient Greek medical texts may be either explicit or implicit. Greek physicians of the fifth and fourth centuries B.C. often used explicit analogy, e.g. when trying to explain unobservable processes within the body by comparing them to observable processes in common objects. Such explicit analogies served several purposes: illustration, exemplification, confirmation, or a combination thereof. - Other analogies are implicit, particularly those originating in metaphors, i. e. in language. While explicit analogies were intended to support only marginal details of medical doctrines, analogies implicit in metaphors occasionally became the nuclei of comprehensive and therapeutically important doctrines, particularly with reference to the crisis of a disease. - Explicit and implicit analogies occur already very early (Homer, eighth century B. C.) and with characteristics which make it possible to assess the specific function of analogy in Greek medical texts of the fifth and fourth centuries B.C.
