Im Rahmen der Popperianischen Bewährungstheorie spielt der Begriff der Strenge eines Tests eine wichtige Rolle. Einige konkurrierende Vorschläge zur Bestimmung der Teststrenge werden vorgestellt, auf ihre Konsequenzen hin analysiert und miteinander verglichen. Gegen Vorschläge von Popper und Watkins bzw. Lakatos und Musgrave werden schwerwiegende Einwände vorgebracht; durch die Erweiterung einer Idee von Zahar lassen sich deren vertretbare Konsequenzen aber erhalten und sogar erklären. Es wird die Ansicht vertreten, daß es im Zusammenhang mit einer rationalen Theorienpräferenz mehr auf ein Optimum an (...) empirischer Kritik als auf ein Maximum ankommt: ein Test muß zwar streng, aber auch fair sein.

Utopian imagination and the principle of hope have fallen on hard times. It has become almost a commonplace that utopian visions are obsolete. The present state of world affairs seems to paralyze utopian thinking. In an age of worldwide exploitation and destruction of nature (the greenhouse effect), epidemic diseases (AIDS), and Bush's “War on Terror,” the future of mankind appears bleak and apocalyptic images dominate our imagination. Especially the collapse of communism in Eastern Europe, if that was supposed to be (...) a utopia at all, has shattered all dreams of century-old social utopias. Utopia is draped in a mourning veil,…. (shrink)

L'article est consacré à la procréation médicalement assistée et aux techniques médicales qui la concernent: les concepts bioéthiques, l'option anthropologique, le dialogue interdisciplinaire et la philosophie de la nature impliqués sont étudiés. Les problèmes concrets du diagnostic préimplantatoire, de la sélection de l'embryon, du clônage, et de la compétence du médecin en matière de conseil sont analysés par l'A.

In his commentary on Aristotle’s Peri hermeneias,1 Abelard distinguishes the form of an expression2 (oratio) from what it says, that is, its content. The content of an expression is its understanding (intellectus). This distinction is surely the most well-known and central idea in Abelard’s commentary. It provides him with the opportunity to distinguish statements (enuntiationes) from other kinds of expressions without implying a diference in their content, since the ability of a statement to signify something true or false (verum vel (...) falsum)3 cannot be found in its content. More precisely, Abelard distinguishes statements both from complete expressions (orationes perfectae) that are not statements but rather questions, requests, commands, etc. and from incomplete expressions, that is, mere word strings (orationes imperfectae), such as homo albus. These kinds of expressions, according to Abelard, do not differ in the understanding they present but in the way they present it. (shrink)

The manipulation of materials, and to some extent also their systematic classification, form an integral part of the skills and culture of all societies. Yet it took long for proper sciences to develop out of many processing procedures, tapping the accumulated knowledge about specific material characteristics. In the late 20th century an overarching science of workable materials emerged: materials science. This concept and term originated from major boosts in materials research during WWII and the Cold War, first financed by the (...) U.S. Department of Defense and the Advanced Research Project Agency. The COSMAT-Report from 1974, written by the American Presidential Science Advisory Committee’s „Committee on the Survey of Materials Science and Engineering" four years after its inception, and subsequent reports heralded in the second institutionalization phase of materials science in the USA and with some delay also elsewhere. As the field continued to expand, the demand grew from within in the late 1990s for disciplinary status. This article sorts these claims from the various camps and sets them in the context of unfolding institutional change. The developments within the German-speaking realm, thus far unduly neglected in these debates, are added. I close with a systematic discussion of eight indicator arguments for or against a convergence of this complex field of research into a single coherent discipline. Against Bensaude-Vincent’s thesis that materials science still is an “aggregation of fragments of knowledge", I argue that by 2010 materials science did indeed achieve disciplinary status in a historically rare and enduring process of discipline formation through “emergence by integration" rather than by differentiation.

Jahrhunderts entspannt. So wurde Kant als Metaphysiker neu entdeckt. Ausstellung und Katalog dokumentieren diese wechselhafte Geschichte der katholischen Rezeption Kants in den vergangenen 200 Jahren.

The riddle of how to democratize the multi-level polity of the EU is answered by pointing to the empirical impact of an unfolding European public sphere. It is argued that there is a self-constituting dynamic of a European public sphere which abets the coupling of transnational spaces of communication with the institutional integration of the EU. From this perspective, democracy is not external to the EU, it is already part of the logic of European institution-building and governance and is fostered (...) by collective learning processes in which definitions of the collective good as well as conditions for appropriate forms of political participation are negotiated. In discussing the case of the EU’s constitutional reform, a theory of democratic functionalism is proposed which accounts for this specific form of democratization of the EU. (shrink)

"Die Bildung muss auf die volle Entfaltung der menschlichen Persönlichkeit und auf die Stärkung der Achtung vor den Menschenrechten und Grundfreiheiten gerichtet sein.

Anknüpfend an Untersuchungen von J. D. Sneed, hat W. Stegmüller eine Explikation von "'revolutionärem' wissenschaftlichem Fortschritt" vorgeschlagen, die auf einer bestimmten Definition der intertheoretischen Relation der Reduktion beruht. Zumindest in seiner bisherigen Fassung erweist sich das von Stegmüller vorgebrachte Kriterium für "revolutionären" wissenschaftlichen Fortschritt jedoch nicht nur als zu weit, sondern auch, wie das Beispiel klassische vs. relativistische Kinematik zeigt, als zu eng.

We start from the assumption that the real valued observables of a quantum system form a Jordan algebra which is equipped with a compatible Lie product characterizing infinitesimal symmetries, and ask whether two such systems can be considered as independent subsystems of a larger system. We show that this is possible if and only if the associator of the Jordan product is a fixed multiple of the associator of the Lie product. In this case it is known that the two (...) products can be combined to an associative product in the Jordan algebra or its complexification, depending on the sign of the multiple. (shrink)
