Michael von Boguslawski

Prochaine séance du séminaire Philform :
lundi 03 novembre de 14h00 à 16h00 dans la grande salle de l'IHPST
Michael von Boguslawski (université d'Helsinki): "Ketonen's logical discovery".

Abstract :
In this talk I will describe Oiva Ketonen's work on logic, in particular his discovery of a sequent calculus with invertible rules. Additionally I will give a brief overview of how logic arrived in Finland. Ketonen being the only student of Gerhard Gentzen - the father of sequent calculus - some recent research on the latter will also be presented.

Allen Mann

Prochaine séance du séminaire Philform :
lundi 27 octobre, grande salle de l'IHPST, 14h-16h.
Allen Mann : IF logic and Kleene algebras

Abstract:
It is well known that the Principle of Bivalance fails in IF logic--there are sentences that are neither true nor false. We will use the techniques of algebraic logic to show that the Principle of Trivalence holds--every sentence has one of exactly three possible truth-values. We will further show that IF logic can be viewed an a first-order extension of Kleene's strong three-valued logic.

Michael Freund

Lundi 13 octobre de 14h à 16h dans la grande salle de l'IHPST, le séminaire Philform reçoit Michael Freund (Paris IV):
'Une théorie de la catégorisation pour les concepts constructibles'.


Résumé: Les concepts constructibles sont ceux que l'on peut définir à l'aide de concepts plus simples dans un processus similaire à celui de l'apprentissage. Pour cette classe de concepts, les notions de base de la théorie de la categorisation et de la théorie du prototype peuvent être simplement modélisées par des relations qualitatives. On obtient ainsi un formalisme qui permet de mieux cerner les problèmes classiques liés à l'appartenance, la typicité relative et la ressemblance. En particulier, le modèle proposé est cohérent avec l'opération de compositionalité, et rend fidèlement compte de phénomènes expérimentaux peu ou mal expliqués par les théories antérieures. La réinterprétation, enfin, de la notions de trait essentiel et de trait typique en termes de relation d'inférence conduit à traitement intéressant dans le cadre de la logique non monotone des notions d'induction catégorielle.

Thibault Gajdos

Lundi 9 juin (14h-16h), le séminaire Philform (IHPST) reçoit Thibault Gajdos(CNRS-Paris 1):

"The Ignorant Observer"

Most prominent models of economic justice (and especially those proposed by Harsanyi and Rawls) are based on the assumption that impartiality is required for making moral decisions. However, although Harsanyi and Rawls agree on that and furthermore agree on the notion that impartiality can be obtained under appropriate conditions of ignorance, they strongly disagree on the consequences of these assumptions. According to Harsanyi, they provide a justification for the utilitarian doctrine, whereas Rawls considers that they imply egalitarianism. We propose here an extension of Harsanyi's Impartial Observer Theorem, that is based on the representation of ignorance as the set of all possible probability distributions over individuals. We obtain a characterization of the observer's preferences that, under our most restrictive conditions, is a convex combination of Harsanyi's and Rawls' criteria. Furthermore, this representation is ethically meaningful, in the sense that individuals' utilities are cardinally measurable and fully comparable. This allows us to conclude that the impartiality requirement cannot be used to decide between Rawls' and Harsanyi's positions. Finally, we defend the view that a (strict) combination of Harsanyi's and Rawls' criteria provides a reasonable rule for social decisions.

P. Mancosu

La prochaine séance du séminaire général de l'IHPST se tiendra le jeudi 22 mai (à l'IHPST) de 11H à 13H. Paolo Mancosu (Université de Berkeley) fera une conférence sur le sujet suivant :
"Quine and Tarski on nominalism"

Le même jour à l'ENS, salle Weil à 16h, se tiendra la première séance de son séminaire sur les théories de la vérité.

Abstract (Quine and Tarski on nominalism):

Quine and Tarski were kindred philosophical spirits. They rejected the
analytic/synthetic distinction and shared a strong distaste for modal
notions. Moreover, both had nominalistic leanings. In this talk I
trace the nominalistic engagement of these two giants of contemporary
analytic philosophy. Using recently discovered materials from the
Quine archive at Harvard, I begin by describing Quine's engagement
with nominalism up to 1940. I will then summarize the impact of the
1940-1941 discussions on nominalism between Carnap, Quine and Tarski
and mention their influence on Goodman. The third part of the talk
will be on Quine's allegiance to nominalism and his subsequent
reluctant acceptance of Platonism. The fourth part of the talk will
then focus on Tarski's defense of nominalism in Amersfoort in 1953.
Finally, I will compare Quine's and Tarski's approaches to nominalism
with some contemporary nominalistic programs (Field, Hellman etc.)

Thomas Forster

Found on T.E. Forster's page.



As a matter of fact, I'm reading Forster's nice book Logic, Induction, and Sets and was looking for a list of errata. A list that, unfortunately, I didn't find.
If you're familiar with the book, by the way, I was concerned with the second paragraph on page 59 : ok, on the third line, I guess, "continuous" should be replaced by "complete" and on the tenth line, it is the set of fn(x) for *n* in N that is of interest (I write fn(x) for the nth iteration of the function f). But on line 6-7, what's going on exactely ? Is it tacitly assumed that x is sound in the sense that x≤ f(x) [for the sup of {x, fx, etc} to be a fixed point of the continuous operator f defined on a poset assumed to be chain-complete] ? Or does it have something to do with inflationary functions, defined a few pages earlier ? The intuition on continuity is, I think, clear enough, but I'm a bit baffled by the details of the development of the discussion in this paragraph.

M. Gomez-Torrente

Mercredi à 17h30 à l'IHPST, le séminaire Philmath reçoit M. Gomez-Torrente (Philosophie, Université de Mexico) :
"Rereading Tarski on Logical Consequence"

Le matin M. Gomez-Torrente donnera un premier exposé de 10h à 12h en salle de réunion du DEC-IJN, sur le thème
"The Sorites, Linguistic Preconceptions, and the Dual Picture of Vagueness".

Abstract ( Rereading Tarski on Logical Consequence):
I will argue against some recent defenses of the view that, in 1936, Tarski always required all interpretations of a language to share one same domain of quantification. I hope to offer a more detailed examination of some of the relevant textual evidence on the issue than in my earlier work. If time permits, I will also offer some new considerations on subsisting issues of interpretation concerning Tarski's views on the logical correctness of certain omega arguments, on the Tarskian proof that Etchemendy took to be modal and fallacious, or on Tarski's appeals to the "common concept of consequence".

Semantics and Philosophy in Europe

SPE colloquium will take place in Paris, May 2-4, 2008.
Arché (St Andrews), the IHPST/Chaire d'Excellence 'Ontological Structure and Semantic Structure' (Paris), Logos (Barcelona), and CSMN (Oslo) are organizing new annual colloquium 'Semantics and Philosophy in Europe' (SPE).

The purpose of the colloquium is to enhance the dialogue between linguists and philosophers and to provide a new forum for presenting research in the interface between linguistic semantics and the various related areas of philosophy (philosophy of language, epistemology, metaphysics, philosophy of mathematics, and philosophy of mind). The colloquium is to take place every year, alternating between Paris, St Andrews, Barcelona, and Oslo.

The abstract reads : "This is a short article that illustrates those aspects of LaTeX that are transformed by LaTeXMathML into a mathml plus html format. While limited in scope, LaTeXMathML nonetheless is capable of transforming a large subset of those elements found in a typical LaTeX article into a mathml empowered webpage. The goal of LaTeXMathML is that of making pure latex coding a "web-friendly" enterprise."

On the Justification of Objectivist Bayesianism
(joint paper with Richard Pettigrew)
Abstract:
The fundamental problem of epistemology is to say when the evidence in an agent's possession justifies the beliefs she holds. In this paper, we defend an Objectivist Bayesian's solution to this problem by appealing to the following fundamental norm: Try to get as close to the truth as possible; in other words: minimize inaccuracy.
We make the underlying notion of inaccuracy mathematically precise, and derive the tenets of Objectivist Bayesianism from the mathematical version of the norm. Finally, we use our account of accuracy to assess Richard Jeffrey's proposed generalization of part of the Bayesian creed, and identify a weakness in his proposal.

Ph. de Rouilhan

Lundi 17 mars (de 14h à 16h dans la grande salle de l'IHPST) Philippe de Rouilhan sera l'invité du séminaire Philform :

Vérité, traduction, signification

Abstract :

— Si la définition tarskienne de la vérité répondait au critère tarskien d’adéquation (la fameuse Convention-T), toute équivalence-T, par exemple:

“Snow is white” est vrai ssi la neige est blanche,

serait déductible de cette définition, et donc logiquement vraie. Mais ce n’est pas le cas, car, si “Snow is white” avait signifié que la neige est rouge, par exemple, cette équivalence-T aurait été fausse.
— Quoi?! Le grand Tarski mis à bas par un petit argument de rien du tout ?! A moins qu’il ne s’agisse d’un paralogisme. Mais alors, où est l’erreur? Etc.

Logic of change, change of logic

Just out: call for papers for the Prague International Colloquium Logic of change, change of logic. The colloquium is dedicated to formal approaches to attitude change. The aim is to bring together the different strands of research on the topic - whether they be logical or probabilistic, whether they deal with change of beliefs or desires or preferences etc. - with an eye to better understanding the philosophical and methodological challenges that change poses, and to getting a clear idea of where the field should be going.
