Paul Hoyningen-Huene

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action.

In Systematicity, Paul Hoyningen-Huene answers the question "What is science?" by proposing that scientific knowledge is primarily distinguished from other forms of knowledge, especially everyday knowledge, by being more systematic. "Science" is here understood in the broadest possible sense, encompassing not only the natural sciences but also mathematics, the social sciences, and the humanities. The author develops his thesis in nine dimensions in which it is claimed that science is more systematic than other forms of knowledge: regarding descriptions, explanations, predictions, the defense of knowledge claims, critical discourse, epistemic connectedness, an ideal of completeness, knowledge generation, and the representation of knowledge. He compares his view with positions on the question held by philosophers from Aristotle to Nicholas Rescher. The book concludes with an exploration of some consequences of Hoyningen-Huene's view concerning the genesis and dynamics of science, the relationship of science and common sense, normative implications of the thesis, and the demarcation criterion between science and pseudo-science.

To begin, the so-called ‘selectivity of historical judgment’ is discussed. According to it, writing history requires a comparative criterion of historical relevance. This criterion contains philosophical elements. In Kuhn’s case, the criterion directs historical research and presentation away from Whiggish historiography by postulating a hermeneutic reading of historical sources. This postulate implies some sort of internalism, some sort of rationality of scientific development, and historical realism. To conclude, some consequences of Kuhn’s anti-Whiggism are discussed.Para empezar, se discute la llamada “selectividad del juicio histórico”. De acuerdo con ello, escribir historia requiere un criterio comparativo de relevancia histórica. Este criterio contiene elementos filosóficos. En el caso de Kuhn, el criterio aleja la investigación y la presentación histórica de la historiografía Whig al postular una lectura hermenéutica de las fuentes históricas. Este postulado implica alguna clase de internismo, de racionalidad del desarrollo científico y realismo histórico. Para concluir, se discuten algunas consecuencias de la postura anti-Whig de Kuhn.

The present volume aims at giving a discussion ot the problems ot reductionism in contemporary life sciences. It contains six papers which deals with reduction/reductionism in different fields ot biological research. Also, the holistic perspective, 1. e. the systems view, is discussed in some ot the papers. The message ot this discussion Is that - whereas reductionism is indeed an important strategy - the systems approach is needed. It is argued by some ot the authors that organisms are complex systems and not just heaps of molecules, 50 that the analytical method does not suffice. Recent developments in systems theory offer the possibility to install a more comprehensive view ot living systems what can be seen particularly in the field ot evolutionary biology. It is true that any organismic activity is molecular, this is to say that it is based on molecular mechanisms. But it is also true that the whole organism displays certain patterns ot behavior which are not just molecular. Any organism can be described as a system ot different levels ot organization different levels ot order and complexity - and it is important, theretore, to study all ot the organizational levels and to see their peculiarities. It should be obvious, however, that there is not one problem ot reduction/reductionism, but that there are many problems linked together and that these problems appear at different levels ot biological research and bio philosophical reflections.

Die Frage nach den grundsätzlichen Erkenntnisgrenzen der Physik wird hier verstanden als die Frage danach, welchen Status die Aussagen der Physik über unbeobachtbare Gegenstände haben, z.B. über den Urknall, über Quarks oder über dunkle Materie. Sind die diesbezüglichen Aussagen der besten physikalischen Theorien einfach wahr oder wenigstens annähernd wahr (realistische Interpretation)? Oder wenigstens wahrscheinlich? Oder handelt es sich um bloße Modellvorstellungen, die für Vorhersagen und ggf. technische Anwendungen praktisch sind, aber keinen Wahrheitsgehalt aufweisen (instrumentalistische Interpretation)? In diesem Aufsatz werden verschiedene solcher Möglichkeiten genauer vorgestellt und die wichtigsten einschlägigen Argumente für und gegen solche Positionen diskutiert.

Fragt man heute Vertreter verschiedener Disziplinen nach der Bedeutung des Hannoveraner Universalgelehrten Gottfried Wilhelm Leibniz, so hort man jeweils immer wieder: Leibniz hat Bedeutendes fur unser Fach geleistet. Leibniz beeindruckt nicht nur durch die Exzellenz seiner Leistung, sondern auch durch die Breite seiner Betatigungsfelder. Der aus einer Ringvorlesung an der Leibniz Universitat Hannover hervorgegangene Band fuhrt nun an die Vielfalt der von Leibniz ausgehenden der Leistungen und Anregungen heran. Insbesondere behandeln die Beitrage die Bedeutung von Leibniz fur die Geschichtswissenschaft, die Theologie, die Philosophie, die Rechtswissenschaft und Juristerei, die Politikberatung, das Versicherungswesen, die Mathematik, die Ingenieurwissenschaften und die Sprachwissenschaft. Abgerundet wird der Band durch eine Einfuhrung von Werner Eisner und eine biographische Skizze aus der Feder von Eike Christian Hirsch.

Many texts on logic are written with a mathematical emphasis, and focus primarily on the development of a formal apparatus and associated techniques. In other, more philosophical texts, the topic is often presented as an indulgent collection of musings on issues for which technical solutions have long since been devised. What has been missing until now is an attempt to unite the motives underlying both approaches. Paul Hoyningen-Huene’s Formal Logic seeks to find a balance between the necessity of formal considerations and the importance of full reflection and explanation about the seemingly arbitrary steps that occasionally confound even the most serious student of logic. Alex Levine’s artful translation conveys both the content and style of the German edition. Filled with examples, exercises, and a straightforward look at some of the most common problems in teaching the subject, this work is eminently suitable for the classroom.

The article discusses Thomas S. Kuhn's impact on the history of science, especially in the United States of America. First, the state of the history of science in the fifties is sketched. Second, Kuhn's particular contribution to the emerging new historiography of science is presented. Third, Kuhn's role in the m-stitutionalization of the history of science in the USA is considered. Finally, some remarks are made on the relation between Kuhn's historiographic work and his book The Structure of Scientific Revolutions

This paper deals with the following questions: What features of modern natural science are responsible for the fact that, of all forms of science, this form is technologically exploitable? The three notions: concept of nature, epistemic ideal, and experiment, suggest the most important components of my answer. I will argue, first, that only the peculiar interplay of the modern concept of nature with an epistemic ideal attuned to it can cast experiment in the specific, highly central role it plays in the pursuit of knowledge about nature. It will then become clear that the form of science in which experiment plays such a role will, necessarily, prove technologically exploitable.
