A teoria da implicatura constitui o principal legado de Paul Grice aos modernos estudos da pragmática linguística. Embora associado à filosofia da linguagem ordinária, seu pensamento não se apresenta marcado pela aversão à sistematização teórica que, segundo se diz, caracterizou essa corrente filosófica. Pelo contrário, a obra do filósofo inglês, apesar de dispersa em artigos só postumamente reunidos em livro, constitui um esforço coerente e rigoroso de analisar os princípios que explicam o comportamento racional do homem. Este ensaio oferece uma (...) tentativa de interpretação da análise que ele propôs para o fenômeno da implicatura, buscando integrar tal análise, progressivamente, ao quadro mais geral de sua filosofia da linguagem e de sua psicologia filosófica. De passagem, é sugerida uma aproximação, quanto aos propósitos, entre o programa filosófico de Grice e certa ensaística crítica do poeta argentino Jorge Luis Borges, sugestão talvez surpreendente, mas que pode se mostrar instrutiva.

The paper studies a simply typed term system Mω providing a primitive recursive concept of parallelism in the sense of Plotkin. The system aims at defining and computing partial continuous functionals. Some connections between denotational and operational semantics → for Mω are investigated. It is shown that → is correct with respect to the denotational semantics. Conversely, → is complete in the sense that if a program denotes some number k, then it is reducible to the numeral nk. Restricting to (...) the primitive recursive kernel Rω of Mω, it is shown that → is strongly normalising with uniquely determined normal forms. The twist is the design of fixed point style conversion rules for constants accounting for parallelly bounded parallel search such that correctness and strong normalisation hold. Thereupon, minor alternations to → bring about that every reduction sequence for a program of Rω terminates either in a numeral nk if the program denotes k, or in the term 0 if the program denotes the “undefined” object. Thus, Rω can be considered a primitive recursive version of Plotkin's PA+·. (shrink)

1. Die Lehre vom Primat der praktischen Vernunft.

Hoe kunnen we ervoor zorgen dat iedereen zich thuis voelt in onze steden? Hoe gaan we om met verschillende culturele feesten en rituelen? Hoe benaderen we ons gemeenschappelijk verleden, dat voor verschillende culturele groepen een andere lading heeft? Of hoe gaan we om met de uiteenlopende opvattingen over homoseksualiteit of de verhouding man-vrouw? Dit zijn enkele voorbeelden van vraagstukken waarbij de ‘kunst van het verstaan’ ingezet zou kunnen worden. Het is immers niet alleen belangrijk om inzicht te krijgen in ‘de (...) ander’, maar ook in ons eigen denkpatroon. In steden met een grote culturele diversiteit kunnen dialogen tussen de verschillende bevolkingsgroepen de wederzijdse erkenning en ook het wederzijdse begrip aanzienlijk bevorderen. Het is een manier om elkaar te ‘verstaan’. Heinz Kimmerle heeft zich de voorbije 25 jaar bekwaamd in ‘de kunst van het interculturele verstaan’. En juist daaraan lijkt behoefte te zijn in onze huidige maatschappij met diverse culturen terwijl er niet altijd evenveel begrip is voor elkaars cultuur. In dit boek onderzoeken de auteurs of dit filosofisch academische werk op het gebied van intercultureel verstaan, een basis kan bieden voor een praktisch dialoogmodel voor het omgaan met de uitdagingen in steden met een grote culturele diversiteit. Zo komen zij tot een model voor dialogen in de dagelijkse praktijk en onderzoeken hoe dit kan leiden tot een meer dialogische levenshouding, die ook op andere gebieden (politiek of economisch) ingezet kan worden. Zij gaan niet alleen in gesprek met elkaar, maar krijgen ook nieuwe inzichten over hun eigen manier van naar de wereld kijken. (shrink)

The last kilometers of the Berlin Wall were finally torn down during this last week before Christmas, but mentally, socially, economically it continues to exist, and for some in what used to be East Berlin it isn’t so clear anymore whether the actual wall made of concrete wasn’t easier to bear. To be sure, the wall that once separated the largest cities in each of the two Germanys is still present as a scar of empty space; but distances have shrunk, (...) and old views of the city have been reestablished—at least geographically, Berlin, no doubt, is slowly becoming one again. However, the social and economic differences as well as the mental walls erected in forty years of separate existence still divide the eastern from the western part. Now that the euphoria of unification has finally subsided, gains and losses are being counted, and many East Germans are beginning to ask themselves whether the price they paid for political freedom was not too high after all. The moral and economic bankruptcy of the old regime daily becomes more apparent: its structures of corruption and repression, its system of total surveillance that had become a part of everyday life and made use of even those whom the state had marginalized. And yet that system, corrupt as it was, had also provided a measure of stability, a predictable life that, although it had restricted individual choice, can now evoke nostalgic memories of warmth and security. Heinz Ickstadt is professor of American literature at the John F. Kennedy Institute for North American Studies at the Free University in Berlin. He has written and edited books on Hart Crane, Thomas Pynchon, and the 1930s, and has published widely on American literature and culture in the late nineteenth century, American modernism, postmodern fiction, and on the relation of literature and painting. A book on the changing functions of the American novel, coauthored with Winfried Fluck, is forthcoming. (shrink)

It is easy to prove in ZF− that a relation R satisfies the maximal condition if and only if its transitive hull R* does; equivalently: R is well-founded if and only if R* is. We will show in the following that, if the maximal condition is replaced by the chain condition, as is often the case in Algebra, the resulting statement is not provable in ZF− anymore . More precisely, we will prove that this statement is equivalent in ZF− to (...) the countable axiom of choice ACω. Moreover, applying this result we will prove that the axiom of dependent choices, restricted to partial orders as used in Algebra, already implies the general form for arbitrary relations as formulated first by Teichmüller and, independently, some time later by Bernays and Tarski.

Die sog. "Schwarzen Hefte" haben umfassender und deutlicher als je zuvor die Verbindungen zwischen Philosophie und Politik bei Heidegger sichtbar werden lassen und damit eine neue Debatte uber den Rang dieses Denkens entfacht. DEnn die dort enthaltenen Texte demonstrieren, dass Philosophie, Metapolitik und Politik bei Heidegger eine Einheit bilden, zu der die Befurwortung des Nationalsozialismus und der Antisemitismus gehoren. INs Zentrum der kritischen Revision ruckt das erste Hauptwerk von 1927, "Sein und Zeit", das nahezu unangefochten als epochaler Beitrag zur Philosophie (...) des 20. JAhrhunderts gilt. DIe "Schwarzen Hefte" fordern eine "Destruktion" dieses Werks auch insofern heraus, als die dort prasentierten Selbstinterpretationen das philosophische Profil dieses Denkens scharfen und neue Gesichtspunkte fur die Diskussion seiner Substanz im philosophischen und ideologischen Kontext des 20. JAhrhunderts eroffnen. 90 Jahre nach seinem Erscheinen stellt sich der philosophischen Forschung die kritische Auseinandersetzung mit "Sein und Zeit" als unabweisbare Aufgabe. IM Vordergrund stehen hierbei zwei Fragen: Wie ist das Unternehmen einer in der "Fundamentalontologie" des Daseins begrundeten temporalen Ontologie der systematischen Intention und Durchfuhrung fachphilosophisch zu beurteilen? Beinhalten die ausgearbeiteten Teile bereits gedankliche Prafigurationen oder Grundlagen fur Heideggers Antisemitismus und Nationalsozialismus? Der Band behandelt diese Problemstellungen aus unterschiedlichen philosophischen, aber auch disziplinaren Perspektiven; er enthalt Beitrage von Charles Bambach, William Blattner, Christoph Demmerling, Emmanuel Faye, Anton M. FIscher, Johannes Fritsche, Hassan Givsan, Marion Heinz, Christoph Jamme, Sidonie Kellerer, Rainer Marten, Daniel Meyer, Livia Profeti, Tom Rockmore und Dieter Thoma. (shrink)
