Der Laureatus dieser Schrift hatte 1986 Hans Jonas eröffnet, daß er an einer Politischen Philosophie arbeite, aus der, wie die Autoren dieses Bandes wissen, nichts geworden ist und von der man auch sonst nicht viel vernommen hat. Jonas wandte damals ein: "Wie wollen Sie der Politischen Vernunft auf die Beine helfen? Das Wissen über die politischen Bewußtseinsvoraussetzungen in uns und ihre Struktur in Gesellschaften ist in esoterische Teilbestände und exoterische politische Religionen, Ideologien und Denkschulen zerfallen. Diese Angelegenheit müßte einer umfassenden (...) Kritik unterzogen werden. Außerdem müßten alle gescheiterten Restitutionsversuche von Platon bis heute auf ihre Prägnanz hin durchgegangen werden. Er nannte Thomas von Aquin, Spinoza, Kant, Hegel, Arendt, Strauss, Voegelin und sich selbst. Sie müßten die Erfahrungen und die Maßstäbe, aus denen das politische Bewußtsein sich ernährt und aufrichtet und die, die es vergiften, frei legen." Im nachfolgenden Gespräch über verschiedene Denker und ihre Texte zur politischen Philosophie tauchten metaphorisch die "leuchtenden Fünkchen" oder "Goldklümpchen" auf, in denen Jonas und der Laureatus lebendige Reste der Politischen Vernunft und die menschheitliche Erinnerung an sie erkannten. "Wir sind womöglich aus einer Jeremiade herausgekommen …" lautete der verheißungsvolle Schlußpunkt des kurzen Gesprächs. Der Laureatus, Jurist und Politikwissenschaftler, konnte während seiner Lehr- und Forschungstätigkeit einige Anregungen für "philosophische Fragestellungen" zu den grotesken und verflachten Formationen des politischen Denkens unserer Zeit geben. Die Autoren sind Claus-Ekkehard Bärsch, Giandomenico Bonanni, Ulrich Diehl, Michael Ensslen, Jürgen Gebhardt, Volker Gerhardt, Manfred Henningsen, Vittorio Hösle, Klaus Kodalle, Peter König, Daniel Krochmalnik, Jan-Ivar Lindén, Reiner Manstetten, Krzysztof Maurin, Peter J. Opitz, Thomas Petersen, Walter Rothholz, Florian Sattler, Stephan Sattler, Julius H. Schoeps, Peter von Sivers, Chiara Staude-Colli, Jakob Staude, Kurt Stenzel, Peter Weber-Schäfer, Reiner Wiehl und James Wood. (shrink)

Der Beitrag der Mathematik zur Naturwissenschaft besteht darin, Erkenntnisse a priori von den (empirischen) Gegenständen der letzteren zu gewinnen und — unter der Voraussetzung, daß es überhaupt Empirisches g i b t -, die Existenz solcher Gegenstände a priori zu sichern. Die Aufgabe der Metaphysik ist es, besondere Begriffe ( in bezug auf die körperliche Natur) zu bilden und die Prinzipien für deren mathematische Konstruktion zu entwickeln. Die so "metaphysischkonstruierten" Begriffe werden dann durch Angabe empirischer Modelle physikalisch interpretiert.

We present an extension of Heyting arithmetic in finite types called Uniform Heyting Arithmetic that allows for the extraction of optimized programs from constructive and classical proofs. The system has two sorts of first-order quantifiers: ordinary quantifiers governed by the usual rules, and uniform quantifiers subject to stronger variable conditions expressing roughly that the quantified object is not computationally used in the proof. We combine a Kripke-style Friedman/Dragalin translation which is inspired by work of Coquand and Hofmann and a variant (...) of the refined A-translation due to Buchholz, Schwichtenberg and the author to extract programs from a rather large class of classical first-order proofs while keeping explicit control over the levels of recursion and the decision procedures for predicates used in the extracted program.

Using Sneed''s metatheory an attempt is made to reconstruct Hodgkin and Huxley''s theory of excitation of cell membranes. The structure of this theory is uncovered by defining set-theoretical predicates for the partial potential models, potential models, and models of the theory. The function of permeability is said to be the only theoretical function with respect to this theory. The main underlying assumptions of the theory are briefly outlined.

In a recent article, O. Ulfbeck and A. Bohr [Found. Phys. 31, 757 (2001)] have stressed the genuine fortuitousness of detector clicks, which has also been pointed out, in different terms, by the present author [Am. J. Phys. 68, 728 (2000)]. In spite of this basic agreement, the present article raises objections to the presuppositions and conclusions of Ulfbeck and Bohr, in particular their rejection of the terminology of indefinite variables, their identification of reality with “the world of experience,” their (...) identification of experience with what takes place “on the spacetime scene,” and the claim that their interpretation of quantum mechanics is “entirely liberated” from classical notions. An alternative way of making sense of a world of uncaused clicks is presented. This does not invoke experience but deals with a free-standing reality, is not fettered by classical conceptions of space and time but introduces adequate ways of thinking about the spatiotemporal aspects of the quantum world, and does not reject indefinite variables but clarifies the implications of their existence.

Inexact limits. On the heap-paradox, Darwinism and recursive grammar. The heap-paradox can be reinforced by a combination with the basic idea of Achilles. The logical pattern of the reinforced heap-paradox will be analysed in a new manner by distinguishing between limited and unlimited transitivity. This analysis makes explicit the constructive character of the paradox. Finally it is shown that the logical pattern of the heap-paradox is applied in popular presentations of Darwinism, in the debate about abortion and in the foundation (...) of recursive theories of grammar.

With this article we introduce a new article category in the journal, as announced in this issue's editorial--Viewpoints & Discussion. Articles under this category are intended to provide authentic and qualified opinions on topics relevant to the journal. These articles and follow-up discussions will pass through an accelerated, mainly editorial, review process. We invite readers to respond to such articles by sharing their personal thoughts and experiences, as well as to initiate new discussions. We hope these contributions will make the (...) journal a site for lively discussions on research practice. For this first "Viewpoint" we have selected a topic that should be of interest to many readers: What key research competencies will researchers and professionals need to have in the future? To introduce the topic, we look into a recent comparative study on this question that compares the situation in eight research-intensive countries. Reports on the study are available for free download, which can serve as a basis for discussion. In keeping with the idea of "Viewpoints & Discussion," no claim to offering a systematic and scholarly account of the topic is intended; the only aim is to throw a spotlight on a theme of current interest and to suggest a few pertinent conjectures and questions for discussion.

The Hangman Paradox has a simple solution. The amazing refutation of the judge's decree rests on the axiom of knowledge-conservation. This axiom is false under unfavourable conditions. You can have a perfect piece of knowledge in the ordinary sense, i.e. a true justified conviction, and yet be unable to conserve it. More interesting than its solution is the element of self-reference, connecting the Hangman via Moore's Paradox and Buridan's Epistemic Paradox with the Liar. This one, I think, has also a (...) natural solution, but less simple. The basic idea is given here, but the technical treatment goes far beyond this paper. It requires a strong, but conservative, extension of classical and three-valued logic to a six-valued logic with infinitely many levels of reflection. (shrink)

Individuals who experience stereotype threat – the pressure resulting from social comparisons that are perceived as unfavourable – show performance decrements across a wide range of tasks. One account of this effect is that the cognitive pressure triggered by such threat drains the same cognitive resources that are implicated in the respective task. The present study investigates whether mindfulness can be used to moderate stereotype threat, as mindfulness has previously been shown to alleviate working-memory load. Our results show that performance (...) decrements that typically occur under stereotype threat can indeed be reversed when the individual engages in a brief mindfulness task. The theoretical implications of our findings are discussed. (shrink)

In Diltheys Philosophie heißt ‘Kultur’ jedes geistige Leben, das durch eine Struktur gestaltet ist und auf gemeinsame Zwecke abzielt. Jede Kultur beruht auf biologischen und anthropologischen Tatsachen und bringt Stetigkeit in das menschliche Leben. Der historische Fortschritt bringt verschiedene Formen der Kultur als Zusammenfassung der geistigen Tatsachen hervor. Solche Kulturen, an denen die Individuen Anteil haben, sind Wissenschaft, Kunst, Philosophie, Religion, Recht und jeder konstante Lebens- und Kommunikationsstil. „Kulturelle Systeme“ sind die äußeren Verbindungen und Institutionen der Kultur, z.B. ist die (...) Kirche das System der Religion, der Staat das System des Rechts und der Gesellschaft. Natürlich lebt das Individuum in je verschiedenen kulturellen Systemen, die voneinander unabhängig sind.

„Empirie, nicht Empirismus“ ist eines von den fundamentalen Prinzipien in Diltheys Denken. Es ist entgegengesetzt der Metaphysik (bes. Hegels und jeder Form von Idealismus) auf der einen und dem Positivismus auf der anderen Seite. Der Positivismus, die vorherrschende Richtung der Philosophie in der 2. Hälfte des 19. Jahrhunderts, wird zwar von A. Comte zu einem System der rein empirischen Philosophie ausgestaltet, aber schon von ihm und dann von einigen seiner Nachfolger in der Wende zu einer ‚positiven Religion‘ aufgelöst. Dilthey wendet (...) sich gegen Comtes Geschichtsphilosophie und gegen die Ausweitung der Grundsätze, die aus den Naturwissenschaften stammen, in die Geisteswissenschaften, etwa die Übertragung empiristischer Grundsätze auf die Geschichte (H. Th. Buckle). Außerdem, so Dilthey, ist der Positivismus nicht in der Lage, eine praktische Philosophie zu entwickeln, die der Vielzahl der Weltanschauungen im 19. Jahrhundert gerecht wird. (shrink)

The theory of practice is according to its self-conception a poststructuralistic research program. It is proceeding on the assumption of a body, that performs his material arrangement with artefacts on the basis of a social habitus in the sense of Bourdieu. In view of recent diagnosis of an affective turn in the social sciences the article fathoms on the basis of Michel Henry’s phenomenology the possibility to understand the (living) body as a body of mood or what he calls flesh. (...) The body which is always in a special mood thus has an influence on acting. In a further step this assumption will broaden the scope to the entire room of interaction, where the practices take place. This includes next to the body of mood, collective moods of social groups and atmospheres as further parameters. (shrink)

Der transzendentalen Subjektivität als sinngebender Instanz liegt in der Husserlschen Phänomenologie ein fundamentaler, der Reflexion nicht zugänglicher Bewusstseinsbereich zugrunde: die absolute Subjektivität.Das basale Defizit der epistemisch ausgerichteten Phänomenologie Husserls ist die Unmöglichkeit einer unmittelbaren Selbstreferenzialität in Bezug auf das eigene Selbst-Bewusstsein. Ausgehend von einem ersten Zugang zur Präreflexivität bei Sartre wird auf Grundlage eines radikalisierten phänomenologischen Designs Michel Henrys und Jean-Luc Marions die Struktur dieser basalen Bewusstseinssphäre systematisch entwickelt.

Against the background of the creation of an EU-wide frame of reference for private law relevant to the Common Market, this study, which was requested by the EU Commission, analyses the dovetailing between contract and tort law on the one hand, and between contract and property law on the other. The study examines the legal orders of almost all the Member States of the EU, illustrates the differences between contractual and non-contractual liability and evaluates the different systems of the transfer (...) of property, of movable and immovable securities as well as trust law. The study comes to the conclusion that the intensive considerations on the creation of a model-law in the area of European private law do not allow these thoughts to be limited to contract law. Such a limitation to the scope of the regarding of this area would probably cause more problems than it would solve, or at any rate not do justice to the needs of the Common Market. (shrink)

The role of Brachyury and other T-box genes in the differentiation of mesoderm and endoderm of vertebrates is well established. Recently, homologues of Brachyury have been isolated from an increasing number of diverse organisms ranging from Cnidaria to vertebrates and insects. Comparative expression and function analysis allows the origin of the mesoderm and the evolution of the developmental role of Brachyury gene family in metazoans to be traced. The data suggest that an ancestral function of Brachyury was to designate a (...) blastoporal region that had distinct properties in induction and axis elongation. A subset of blastoporal cells expressing Brachyury and other genes that convey specific mesodermal functions may have segregated as a distinct cell population from this region in the course of mesoderm evolution.
