Le rapport de l’âme et du corps est caractérisé par les deux faits également fondamentaux d’une unité stricte entre l’âme et le corps, et en même temps d’une dualité profonde entre l’âme et le corps. Ce paradoxe ne devient compréhensible que par une explication de principe sur'la loi de causalité. Une analyse détaillée prouve que l’action réciproque dans le monde n’est possible que par l’action de forces spirituelles sur un médium corporel purement passif. En conséquence, l’âme agit, comme force de (...) la nature, sur le corps humain, organisé par des actions spirituelles. (shrink)

History of science's spatial turn has focused on the horizontal dimension, leaving the role of the vertical mostly unexplored as both a condition and object of scientific knowledge production. This special issue seeks to contribute to a burgeoning discussion on the role of verticality in modern sciences, building upon a wider interdisciplinary debate about the importance of the vertical and the volumetric in the making of modern lifeworlds. In this essay and in the contributions that follow, verticality appears as a (...) condition of knowledge production—a set of movements and mobilities, technical challenges, political negotiations, and bodily hardships—and an object of scientific inquiry, requiring new techniques of mapping and visualisation and generative of new insights into physical processes and temporal change. By foregrounding the vertical, historians of science can gain new insights and tell new stories about how science is done in the field, the observatory, and the laboratory, and about how those sciences have helped build a modern, three-dimensional world.

In the interwar years the Gran Paradiso ibex population followed two subsequent, contrasting trends: a steady rise once the national park was established in 1922, followed by a precipitous fall after the Fascist regime took direct control of conservation in 1934, which almost led to the colony’s extinction. This paper addresses the issue of how models taken from population ecology may inform historical narratives. The data for the interwar years were analyzed using a statistical model based on climate and population (...) density, which has proved reliable for most of the post-World War II period. The article highlights the pivotal role of anthropic variables in determining the inter-war trends and how these are best analyzed using historical scholarship. (shrink)

In June 1947 Paul Tillich signed a contract with The University of Chicago Press for a “Systematic Theology” in two volumes. Having published the first volume in April 1951, he asked the publisher to split the second volume into two parts, which were published in 1957 as volume II and 1963 as volume III. In this article the different editions of “Systematic Theology” are described, and the economic aspects of writing and publishing this very influential academic book are explained. Many (...) unknown sources are presented. Some of them show Tillich as an author in real despair. (shrink)

By the end of April 1923, Paul Tillich’s Das System der Wissenschaften nach Gegenständen und Methoden (1981: The System of the Sciences according to Objects and Methods) was published by the German publishing house Vandenhoeck & Ruprecht in Göttingen. Based on numerous source documents from the publishers’ archives and particularly on the correspondence between the publishers Wilhelm and Gustav Ruprecht, hitherto unknown but now edited and commented on here, the present article explains that Tillich wrote his System of the Sciences (...) primarily for the publisher. It was Emanuel Hirsch who established the connection between them as the publishing house was looking for a new editor for their popular series Wege zur Philosophie (Ways to Philosophy), published since 1911. After Hirsch having brought Tillich into play, Wilhelm Ruprecht could convince the Berlin “Privatdozenten” to become the new editor of the series. As to the series, Tillich unfolded the concept of a comprehensive system design which covered 65 topics, i. e. forthcoming volumes. When the publisher then demanded that Tillich prove his abilities to write comprehensively in common language by providing a sample of a first issue of the series, he began to work on his System der Wissenschaften. Although this text contained all sorts of ideas and concepts, it was certainly not very well suited as an introduction to a series of popular accounts of the central themes and matters of philosophy. In the end, the System was published, although not as a volume of the series as having been announced by the publishing house in 1922, but as a text in its own right. (shrink)

Als große, integrale Kunstform wird Musik zunehmend unterschätzt. Die Anforderungen ihres Wissens und Könnens wollen die Menschen - zumal in den westlichen Konsumgesellschaften - immer weniger erfüllen. So verkürzen sie ihr Bild von sich selbst. Doch ihnen kann ein besseres Bild geboten werden.0Was heute als Musik beliebt ist, gehört weithin zur Breitenkultur. Musikalische Hochkultur hingegen gilt als elitär. Doch deren seelische und geistige Vermögen konnten in früheren Jahrhunderten in vielen Menschen geweckt werden, weil Breitenkultur und Hochkultur ineinander verflochten waren. Erst (...) mit der Aufklärung des 18. Jahrhunderts kamen vereinfachende und einseitig suggestive Musikauffassungen auf, die mittlerweile weltweite Geltung beanspruchen. Doch in ihnen verkürzen die Menschen ihr Bild von sich selbst. Dieses Bild muss daher nun einer kritischen Revision unterzogen werden. Es müssen die seelischen und geistigen Vermögen, die Musik als integrales Wissen und Können wecken kann, erneut bewusst werden. Und sie müssen bewusst werden als Teil solcher Vermögen, durch die der Einzelne in einer globalisierten Welt, die ihn immer mehr zu überfordern, zu entmündigen und zu entmächtigen trachtet, zumindest einen Teil seines Lebens in die eigene Hand nehmen kann.

Light mediates plant development partly by orchestrating changes in gene expression, a process which involves a complex combination of positive and negative signaling cascades. Genetic investigations using the small crucifer Arabidopsis thaliana have demonstrated a fundamental role for the down‐regulation of light‐inducible genes in response to darkness, thus offering a suitable model system for investigating how plants repress gene expression in a developmental context. Rapid progress in eukaryotic gene repression mechanisms in general, and light control of plant gene expression in (...) particular, sheds new light on how a class of ten pleiotropic COP/DET/FUS genes might function to down‐regulate light‐inducible genes in plants.

This volume develops a fundamentally different categorical framework for conceptualizing time and reality. The actual taking place of reality is conceived as a “constellatory self-unfolding” characterized by strong self-referentiality and occurring in the primordial form of time, the not yet sequentially structured “time-space of the present.” Concomitantly, both the sequentially ordered aspect of time and the factual aspect of reality appear as emergent phenomena that come into being only after reality has actually taken place. In this new framework, time functions (...) as an ontophainetic [H1] platform, i.e., as the stage on which reality can first occur. Events are merely the “tracks” that the actual taking place of reality leaves behind on the co-emergent “canvas’’ of local spacetime. -/- The view of time proposed here is particularly relevant to the recent debate over the “ER=EPR” conjecture targeting the relation between quantum physics and general relativity theory. The novelty of this radically different framework is that it allows quantum reduction and singularities to be addressed as inverse transitions into and out of the factual layer of reality: In quantum physical state reduction, reality “gains” the chrono-ontological format of facticity, and the sequential aspect of time becomes applicable. In singularities, by contrast, the opposite happens: Reality loses its local spacetime formation and reverts back to its primordial, pre-local shape – making the use of causality relations, Boolean logic and the dichotomization of subject and object obsolete in the process. -/- For our understanding of the relation between quantum and relativistic physics, this new view opens up fundamentally new perspectives: Both are legitimate views of time and reality; they simply address very different chrono-ontological portraits, and thus should not lead us to erroneously prefer one view over the other. -/- The task of the book is to provide a formal framework in which this radically different view of time and reality can be suitably addressed. The mathematical approach is based on the logical and topological features of the Borromean Rings, and draws upon concepts and methods from algebraic and geometric topology – especially the theory of sheaves and links, group theory, logic and information theory in relation to the standard constructions employed in quantum mechanics and general relativity, shedding new light on the problems of their compatibility. The intended audience includes physicists, mathematicians and philosophers with an interest in the conceptual and mathematical foundations of modern physics. (shrink)
