According to the semantic view of scientific theories, theories are classes of models. I show that this view -- if taken seriously as a formal explication -- leads to absurdities. In particular, this view equates theories that are truly distinct, and it distinguishes theories that are truly equivalent. Furthermore, the semantic view lacks the resources to explicate interesting theoretical relations, such as embeddability of one theory into another. The untenability of the semantic view -- as currently formulated -- threatens to (...) undermine scientific structuralism. (shrink)

These five essays on Hegel give the English-speaking reader a long-awaited opportunity to read the work of one of Germany's most distinguished philosophers, Hans-Georg Gadamer.

A classic of phenomenology and existentialism and arguably Jonas's greatest work, The Phenomenon of Life sets forth a systematic and comprehensive philosophy -- an existential interpretation of biological facts laid out in support of Jonas ...

Argument quality has consistently been shown to have strong and lasting persuasive effects. The question is what criteria people use to distinguish strong from weak arguments and how these criteria relate to the ones proposed in normative argumentation theory. In an experiment 235 participants without training in argumentation theory rated the acceptance of 30 claims about the desirability of a consequence that were supported by either an argument from analogy, from authority, or from consequences. The supporting arguments were systematically manipulated (...) to violate argument type specific criteria. Participants proved sensitive to the violation of most, but not all, argument type specific criteria. From a normative perspective these findings suggest that people act in a fairly adequate way. These findings also enable a more precise description of what people may do when critically appraising arguments, which has important implications for the use of argument quality as a methodological tool in persuasion research.

This essay argues that non-linguistic animals qualify not just for externalist notions of rationality (maximizing biological fitness or utility), but also for internal ones. They can act for reasons in several senses: their behaviour is subject to intentional explanations, they can act in the light of reasons - provided that the latter are conceived as objective facts rather than subjective mental states - and they can deliberate. Finally, even if they could not, it would still be misguided to maintain that (...) animals are capable only of (mechanical) behaviour, not of (intentional) action. (shrink)

Wittgenstein's remarks about family resemblance in the Philosophical Investigations should not be construed as implying a comprehensive theory of universals. They possess, rather, a defensive function in his exposition. The remarks allow one, nevertheless, to draw certain general conclusions about how Wittgenstein thought about concepts. Reflection on the notion of family resemblance reveals that kinship and similarity considerations intersect in it in a problematic fashion.

This paper presents the model of ‘bounded revision’ that is based on two-dimensional revision functions taking as arguments pairs consisting of an input sentence and a reference sentence. The key idea is that the input sentence is accepted as far as (and just a little further than) the reference sentence is ‘cotenable’ with it. Bounded revision satisfies the AGM axioms as well as the Same Beliefs Condition (SBC) saying that the set of beliefs accepted after the revision does not depend (...) on the reference sentence (although the posterior belief state does depend on it). Bounded revision satisfies the Darwiche–Pearl (DP) axioms for iterated belief change. If the reference sentence is fixed to be a tautology or a contradiction, two well-known one-dimensional revision operations result. Bounded revision thus naturally fills the space between conservative revision (also known as natural revision) and moderate revision (also known as lexicographic revision). I compare this approach to the two-dimensional model of ‘revision by comparison’ investigated by Fermé and Rott (Artif Intell 157:5–47, 2004 ) that satisfies neither the SBC nor the DP axioms. I conclude that two-dimensional revision operations add substantially to the expressive power of qualitative approaches that do not make use of numbers as measures of degrees of belief. (shrink)

Ohne Ubertreibung kann man sagen, dass der Philosoph Wilhelm Friedrich Weischedel - ein Schuler Martin Heideggers - im Problem des Nihilismus, d.h. des Todes Gottes und des damit verbundenen Sinn- und Seinsverlusts, die tiefste Herausforderung des Denkens sah. Vor allem seine Philosophische Theologie entfaltet dieses Grundproblem. Uber verschiedene denkerische Schritte gelangt er zu einer ihm plausibel erscheinenden Antwort auf den Nihilismus, zum Gott der Philosophen. Diese Schritte aber wurden Gegenstand heftiger Kontroversen. Sowohl theologische wie auch philosophische Kritiker haben sie abgelehnt. (...) In der vorliegenden Studie setzt sich der Verfasser mit dem historischen Nahrboden, der Entwicklung und den Schwierigkeiten der Weischedelschen Gotteslehre auseinander. Denn nur auf der Basis einer solchen Auseinandersetzung lasst zich klaren, ob diese Lehre heute ein Licht im Schatten des Nihilismus sein kann. (shrink)

Modern belief revision theory is based to a large extent on partial meet contraction that was introduced in the seminal article by Carlos Alchourrón, Peter Gärdenfors, and David Makinson that appeared in 1985. In the same year, Alchourrón and Makinson published a significantly different approach to the same problem, called safe contraction. Since then, safe contraction has received much less attention than partial meet contraction. The present paper summarizes the current state of knowledge on safe contraction, provides some new results (...) and offers a list of unsolved problems that are in need of investigation. (shrink)

This article addresses the two most important areas of potential conflict between inferentialism and naturalism, namely normativity and rationality. Concerning the first, it sides with inferentialism, while at the same time developing a normativist position less vulnerable to naturalistic objections. There is nothing problematic or mysterious about semantic normativity or normativity in general. But one needs to distinguish different types of normativity and recognize that statements of norms can be perfectly truth-apt. Concerning the second area of conflict, my verdict is (...) partly naturalistic. It rejects overly intellectualist accounts of the normative practices that underlie meaning and content. The article ends with a plea for an ‘anthropological’ naturalism that eschews both ontological supernaturalism and epistemological naturalism. (shrink)

Hoewel René Descartes zijn leven lang onderdaan bleef van de Franse koning, verbleef hij vele jaren in de Republiek der Nederlanden. In veel opzichten paste hij zich aan de Nederlanden aan: hij beheerste de taal, kleedde zich naar de gewoonten van het land, had een groot aantal Nederlandse boezemvrienden en invloedrijke relaties en trad uitvoerig in discussie met Nederlandse geleerden. De bekendheid die hij in Frankrijk had verworven, zorgde ervoor dat hij voortdurend in de belangstelling stond. Terwijl zijn denken juist (...) gebaat was bij rust. Die omstandigheden vond hij in Nederland.0Filosoof en schrijver Hans Dijkhuis herleidt aan de hand van vele bronnen zo exact mogelijk de verblijfplaatsen van Descartes en beschrijft diens omgang met tijdgenoten. Veel van de episodes en gebeurtenissen komen in andere biografieën niet of nauwelijks aan de orde, maar zijn van belang voor een vollediger inzicht in zijn leven en denken. Zijn verblijf in Alkmaar is bijvoorbeeld grotendeels onbekend, maar vormde in zekere zin een keerpunt in zijn leven. (shrink)

Theoretical works in economics usually have a core consisting of proofs that a “model-economy” has certain properties. The economist constructs a model that can be looked on as a description of an economy, and then proves that certain relations hold in this economy and/or that certain relations in this economy depend on certain specific characteristics. The model-economy is usually described as simplified or idealized.

Rudolf Carnap hat nur im Vorwort zum „Logischen Aufbau der Welt“ Bemerkungen zum Verhältnis seiner wissenschaftlichen Arbeit zur Kunst und Architektur seiner Zeit veröffentlicht. Aber sein emphatisches Bekenntnis zur Moderne der 20er-Jahre hat bisher nur selten Aufmerksamkeit in der philosophiegeschichtlichen Sekundärliteratur gefunden. In meinem Beitrag versuche ich in den ersten beiden Abschnitten, seinen kulturellen Hintergrund seit seiner Schul- und Studentenzeit zu skizzieren und dann seine persönlichen Kontakte und Austauschbeziehungen mit Vorkämpfern der Moderne wie Franz Roh und Siegfried Giedion zu beschreiben. (...) Nach diesen Vorbereitungen wird die Frage gestellt, ob und in wieweit Carnaps Philosophie selbst als ein Teil der Bewegung der Neuen Sachlichkeit verstanden werden kann oder sogar muss. Zur Beantwortung werden eine Reihe von Charakteristika dieses Zeitgeist-Phänomens aus den – gleichzeitig mit Carnaps „Aufbau“ erschienenen Werken der Genannten – herauspräpariert und dann untersucht, ob diese Kriterien sich auch im Werk Carnaps finden. Das Ergebnis ist, dass man ihn mit Fug und Recht als „Philosoph der Neuen Sachlichkeit“ bezeichnen kann. (shrink)

Die Herausforderung der modernen Technik für die ethische Orientierung des menschlichen Handelns wurde und wird in immer brisanterer Form zum Thema einer Theorie von einer erweiterten Verantwortlichkeit. Besonders Jonas’ Buch Das Prinzip Verantwortung ist hierzu als Vorreiter gewürdigt worden. Es war in der Tat Jonas, dem es gelang, mit seinem Buch weit über die Fachzirkel hinaus die größere Öffentlichkeit zu erreichen. Er stellte zu Recht fest, durch das Übermaß der wissenschaftlich multiplizierten technologischen Macht wachse dem Menschen »eine neue, nie zuvor (...) erträumte Dimension der Verantwortung « zu.

The review discusses four recent books and collections that approach in different ways the role of aesthetics in Nietzsche’s work, both as a question of poetic expression and as the shaping of sensibility. They testify to a deepening interest in the processes through which he forged his unique style. This involves micro-analyses of the composition of Nietzsche’s writings from the raw material of his notebooks. It also involves biographical and material contexts, as in Tobias Brücker’s monograph on the composition of (...) The Wanderer and His Shadow. Instead of accepting the dichotomy between a Dichterphilosoph and a philosopher for whom style was merely an instrument for formulating truths, these books display in different ways how in the case of Nietzsche this dichotomy breaks down and gives way to a widened concept of philosophical writing that includes many different genres. Other works by Nietzsche discussed are Zarathustra and The Gay Science, and also Ecce Homo. Nietzsche seduced with his art, but he also saw through the art of seduction as practiced by the artist, opting for a position beyond the conventional split between poetics and philosophy. (shrink)

La philosophie scientifique de nos jours prend son point de départ, non dans les propositions certaines des mathématiques, suivant l’exemple de Descartes, mais dans les énoncés probabilitaires des sciences empiriques, dont le modèle est la physique. Les mathématiques sont certaines, mais vides de contenu : ce sont de pures tautologies qui n’imposent aucune restriction au réel. Les éпоncés de la physique sont doués de contenu, mais ils ne sont pas certains parce qu’ils formulent des prédictions : ils ne sont pas (...) à considérer comme des propositions vraies, mais comme les mises d’un joueur, et, comme tels, ils relèvent d’une logique probabilitaire, dont la logique classique n’est qu’un cas très particulier.
