Les conciles, qui font partie de la vie de l’Eglise depuis les temps les plus anciens, sont fortement marqués par leur contexte culturel respectif, de sorte que l’institution a subi, au fil des siècles, nombre de changements extérieurs. Malgré cela, une même essence est reconnaissable. Ainsi, pour tous les conciles, il s’agit d’établir et de constater un consensus tant en matière de discipline ecclésiastique que dans les questions de foi. C’est en ce sens que les anciens conciles entendaient être le (...) lieu d’émergence d’un double consensus, horizontal et vertical. Malgré les aléas de l’histoire, qui malmenèrent souvent cet idéal consensuel, les conciles veulent avoir en commun avec l’Eglise leur caractère à la fois divin et humain.Councils, which have been part of the Church’s life since the earliest times, have been strongly marked by their respective cultural contexts, which has resulted in a number of exterior changes in the institution over the centuries. In spite of this, the same essence is recognizable. Thus, the point for all the councils has been to establish and state a consensus concerning ecclesiastical discipline, as well as questions of faith. It is in this sense that the early councils were understood as being the place where a twofold consensus – horizontal and vertical – would emerge. Despite the accidents of history, which often made it difficult to achieve this consensual ideal, the councils have sought to share with the Church their divine and human character. (shrink)

I wish to express, first of all, my profound gratitude to Professor J. M. Bochenski, without whose assistance the present work would have not been possible. To be concise, I would like to state that his contribution to this book may be viewed at three levels: (1) that of the general spirit, (2) that of the specific ideas, theses or approaches which are expressed in its pages, (3) that of this work qua doctoral dissertation. The general spirit which has guided (...) my research coincides with that underlying Professor :Oochenski's own works, in particular his Formale Logik (Munchen 1956). Moreover, the particular occasion which suggested my investigation was a statement included in that book according to which the literature in the field still lacked a detailed work on Frege (p. 317). I wish, likewise, to express my gratitude to other professors of the University of Fribourg for their generous help. I mention especially Professors P. Wyser, M. D. Philippe, N. Luyten, and V. Kuiper. I have also benefited from Professor E. Specker's lectures at the Eidge nossische Technische Hochschule (ZUrich) and from Professor Olof Gigon's lectures at the University of Bern. From an earlier period I wish to express my gratitude to the professors of the philosophy department of the Universidad Nacional de Buenos Aires, especially the late Professor Francisco Romero. The Swiss National Library (Bern) has greatly facilitated access to bibliographical sources, and the library of the University of Munster (Westphalien) has kindly provided microfilms of Frege's Nachlap.

: Before he studied philosophy under Bertrand Russell, Ludwig Wittgenstein was trained as an engineer at the Technische Hochschule in Berlin. He then worked as a graduate research engineer at the University of Manchester, where he designed a variable volume combustion chamber and received a patent for an innovative propeller design in 1911. I argue that the methodology of contemporary aeronautical engineering research, involving the systematic use of experiments and scale models, affected the Bild theory of language in (...) the Tractatus Logico-Philosophicus. The principle of similitude, underlying the mathematical resolution of scale effect problems associated with wind tunnel research on models, is reflected in the law of projection in the Tractatus.

After a short introduction into the history of the building of the Physics Institute of the University of Breslau, the development under Otto Lummer is sketched: influenced by the newly founded Technische Hochschule, the building as well as the faculty, were enlarged. The collection of instruments for instruction and research was built up and the cooperation with industry and with guests from abroad strengthened. Young scientists were promoted, making Lummer’s institute into one of the leading ones in optics (...) at that time. (shrink)

In 1922 the University of Buenos Aires (UBA) Council approved a motion to send an invitation to Albert Einstein to visit Argentina and give a course of lectures on his theory of relativity. The motion was proposed by Jorge Duclout (1856–1927), who had been educated at the Eidgenössische Technische Hochschule, Zurich (ETH). This proposal was the culmination of a series of initiatives of various Argentine intellectuals interested in the theory of relativity. In a very short time Dr. (...) Mauricio Nirenstein (1877–1935), then the university's administrative secretary, fulfilled all the requirements for the university's invitation to be endorsed and delivered to the sage in Berlin. The visit took place three years later, in March–April 1925. (shrink)

The ways in which the sciences have been delineated and categorized throughout history provide insights into the formation, stabilization, and establishment of scientific systems of knowledge. The Dresdener school’s approach for explaining and categorizing the genesis of the engineering disciplines is still valid, but needs to be complemented by further-reaching methodological and theoretical reflections. Pierre Bourdieu’s theory of social practice is applied to the question of how individual agents succeed in influencing decisively a discipline’s changing object orientation, institutionalisation and self-reproduction. (...) Through the accumulation of social, cultural and economic capital, they succeed in realising their own organisational ideas and scientific programs. Key concepts for the analysis include the struggle for power and resources, monopolies of interpretation, and the degree of autonomy. A case study from the Aachener Technische Hochschule shows that the consolidation of ferrous metallurgy can be conceived as a symbolical struggle between Fritz Wüst, professor for ferrous metallurgy, and the German Iron and Steel Institute, leading to a construction of a system of differences in which scientists accepted being scientists rather than entrepreneurs, and entrepreneurs accepted becoming entrepreneurs and renounced science.

Ludwig Wittgenstein was trained as a scientist and an engineer. He received a diploma in mechanical engineering from the Technische Hochschule in Charlottenburg, Berlin, in 1906, after which he did several years of research on aeronautics before turning to the full-time study of logic and philosophy. Hertz, Boltzmann, Mach, Weininger, and William James, all important influences on Wittgenstein, are authors whose work was both philosophical and scientific. The relationship between everyday life, science, and philosophy, is a central concern (...) throughout the course of his writing. He regarded philosophy, properly conducted, as an autonomous activity, a matter of clarifying our understanding of language, or investigating grammar. Wittgenstein thought philosophy should state the obvious as a way of disabusing us of the desire to formulate philosophical theories of meaning, knowledge, language, or science, and was deeply opposed to the naturalist view that philosophy is a form of science. In his later work, Wittgenstein rejected systematic approaches to understanding language and knowledge. Wittgenstein’s answer to the Socratic question about the nature of knowledge is that it has no nature, no essence, and so it is a mistake to think one can give a single systematic answer:If I was asked what knowledge is, I would list items of knowledge and add “and suchlike.” There is no common element to be found in all of them, because there isn’t one.

Die Berufungspolitik der 1870/80er Jahre zur Besetzung der mathematischen Lehrstühle schuf wesentliche Voraussetzungen für die Erhöhung des Niveaus der mathematischen Lehre und für die Etablierung der mathematischen Forschung an den Technischen Hochschulen. Im Vordergrund ihrer Analyse stehen Fragen nach den Gesichtspunkten, unter denen die Mathematiker ausgewählt und berufen wurden, nach dem Einfluß führender Mathematiker auf die Besetzung der Lehrstühle sowie nach Motiven für die Annahme bzw. Ablehnung eines Rufes an eine Technische Hochschule. Grundlage des vorliegenden Beitrages sind bisher (...) unveröffentlichte Unterlagen über Berufungsverhandlungen aus dem Zentralen Staatsarchiv Merseburg .In the 1870s and 1880s the policy of appointments to the chairs of mathematics gave rise to an increase in the level of mathematical teaching as well as to the establishment of mathematical research at the colleges of technology. First of all our analysis investigates aspects of choosing and appointing mathematicians and the influence of leading mathematicians on the appointments; then we consider motives to accept or to reject a call to a college of technology. The paper is based on unpublished sources referring to appointment affairs, which are available in the Zentrales Staatsarchiv, in Merseburg in the German Democratic Republic. (shrink)

Originally presented as the author's thesis, Technische Hochschule, Aachen, 1975.

In this paper, I delineate the first pages of a philosophical genealogy which outlines the cornerstones of a philosophy of bio-technical forms. In so doing, the essay contributes to the philosophical understanding of some key scientific concepts. In particular, it analyses the philosophical and historical preconditions, the epistemic assumptions, as well as the ontological commitments of the concept of form as used in digital design and in bionics. In the first section, I investigate Ernst Kapp’s philosophy of technical forms. In (...) the second section, I analyse the emergence of biotechnology, today’s bionics, as an independent technical discipline. At the beginning of the 20th century, the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) founded this discipline with the aim of imitating the technical solutions chosen by nature. In the conclusion, I draw broader conclusions about the philosophy of bio-technical forms. Particularly, I argue, first, that the role of materiality and form-intrinsic propriety is of central importance in processes of form design. Second, I define morphology as a theory of possible constructions of forms in space and not, as in evolutionary biology, a science of the changes of forms in time. This characterises what I have called the ontological turn in form-design disciplines: nature operates technically to conceive new forms. (shrink)

Das Werk entkräftet das Vorurteil, Kants Philosophie sei für eine Reflexion der kulturellen Welt unzureichend. Klingner entwickelt die Option einer Kulturphilosophie als Theorie technischer Vernunft mit Bezug auf den kantischen Kulturbegriff und auf seinen Philosophiebegriff. Damit erweist sich zugleich, dass eine kantische Kulturphilosophie rekonstruierbar und in ihrem Gehalt auch heute noch diskussionswürdig ist.

Das Nichtwissen ist in aller Munde. Von Nichtwissenskulturen in der zweiten oder reflexiven Moderne ist die Rede, von Agnotologie als neuem Forschungszweig, von wicked problems und ihren clumsy solutions. Wo Nichtwissen sich durch Komplexitäts­steigerung unwiderruflich im zu Wissenden einnistet, fordert es als Grenze, Schranke und Kehrseite des Wissens die sogenannte Wissensgesellschaft heraus. Vor allem Risiko­poten­ziale und Gefahren kommen hier in den Blick, von denen wir gerade genug wissen, um Wissensansprüche zu formulieren, die sich womöglich nie einlösen lassen. Das klassisch erkenntnistheoretische (...) Problem: „Was können wir wissen?“ steht heute in einem Spannungsverhältnis zu der wissenspolitischen Frage: „Was müssen wir wissen?“ Was wir wissen müssen, ist einerseits so viel wie nötig, wenn es um Fragen von Sicherheit und Gesundheit geht – andererseits aber so wenig wie möglich, wenn es in Alltag, Wirtschaft oder Wissen­schaft darauf ankommt, Wissen an technische Systeme oder Expertenkulturen zu delegieren. Bezeichnet politisch handlungsorientiertes und wissenschaftliches Nichtwissen zunächst ein Defizit, ist technisches Nichtwissen gleichermaßen erstrebenswert und problematisch. Einige, die Technik für angewandtes Wissen halten, mögen darin eine contradictio in adjecto sehen, manche sich um eine dem technischen Nichtwissen geschuldeten Technik­feindlichkeit sorgen, andere daraus die nötige Demut gegen verstiegene Allmachts­fantasien beziehen, während ihre Gegenspieler von Maschinen träumen, die über den Horizont intellektueller Nachvollziehbarkeit immer weiter hinauseilen.

Ich erörtere die beiden folgenden Thesen:1. Der technisch-wissenschaftliche Fortschrift ist als Ganzes nicht zu steuern, und zwar gerade dann nicht, wenn er eine Zivilisation wie die unsere westliche total durchdringt. Die Nichtplanbarkett des Gesamtprozesses ist seine wichtigste Rahmenbedingung. Man hat aber einen ideologischen Begriff von Rationalität, wenn man den Entwicklungszug des 'Fortschrifts' deshalb als 'irrational' bezeichnen würde.2. Die Akzeptierung des Umstands, daß der technisch-wissenschaftliche Fortschritt nicht planbar ist, ist einer der augenfälligsten Preise, die wir für die Erhaltung der liberalen Demokratie (...) bei uns zu zahlen haben.

Current advances of modern medicine, in our diagnostic procedures and therapeutic options, are rapidly progressing. We often concentrate, however, merely on scientific aspects of medical problems rather than including a patient-centred approach and ethical aspects of a disease. Important for a healthy balance between specialism and integrative medicine are those discussed in the article. Suchare a critical appraisal of medical technology, a re-evaluation of patients and their illness, our detailed history-taking and thorough clinical examination and a better understanding and approach (...) to drug diversities. Drug effects and interactions as well as psychosocial aspects of patients and their lives should be fully acknowledged. These themes of daily medical activities as mentioned above are suggested tobe further enriched by macroethics at the beginning and end of life. (shrink)
