En 2008, l’audition à l’Assemblée nationale est imposée à Bernard Tapie, homme d’affaires, à la suite du scandale Crédit lyonnais. Elle traite de la décision de verser à Tapie une somme avoisinant 390 millions d’euros, dont – et c’est le point qui indigne le plus le public et les députés – 45 millions d’euros de préjudice moral prélevés sur le trésor public. Les députés abordent toutes les accusations relatives à l’affaire, mettant l’accent sur le manque de morale du personnage. Tapie (...) doit justifier la décision de l’arbitrage et redorer son image. Pour ce faire, il fait appel à une panoplie de stratégies, dont des arguments éthiques. Que peut-on apprendre de ces interactions au cœur d’un des scandales français les plus retentissants de la décennie – en particulier sur la façon dont chaque acteur cherche à gérer sa propre image?

(2012). Reasoning without believing: on the mechanisation of presuppositions and partiality. Journal of Applied Non-Classical Logics: Vol. 22, No. 4, pp. 295-317. doi: 10.1080/11663081.2012.705962.

We present a mathematical approach to defeasible reasoning based on arguments. This approach integrates the notion of specificity introduced by Poole and the theory of warrant presented by Pollock. The main contribution of this paper is a precise, well-defined system which exhibits correct behavior when applied to the benchmark examples in the literature. It aims for usability rather than novelty. We prove that an order relation can be introduced among equivalence classes of arguments under the equi-specificity relation. We also prove (...) a theorem that ensures the termination of the process of finding the justified facts. Two more lemmas define a reduced search space for checking specificity. In order to implement the theoretical ideas, the language is restricted to Horn clauses for the evidential context. The language used to represent defeasible rules has been restricted in a similar way. The authors intend this work to unify the various existing approaches to argument-based defeasible reasoning.

Dos pasajes de las Historiae de Curcio Rufo pueden ser leídos en el marco de la tradición de la historiografía romana de incluir discursos de enemigos extranjeros para expresar visiones críticas del imperialismo romano. El discurso de Darío antes de la batalla de Gaugamela (4.14.9-26) y el de un embajador escita (7.8.12-30) son analizados en este trabajo para demostrar que, detrás de una lectura literal de censura a Alejandro Magno, aparece un fuerte reproche a la expansión imperial de Roma.

Die Anthroposophie Rudolf Steiners (1861-1925) ist eine der wichtigsten esoterischen Traditionen der Gegenwart. Ihre Bedeutung verdankt sie nicht nur Steiners stark philosophisch geprägter Weltanschauung aus dem Geist des Okkultismus, sondern vor allem den Praxisfeldern: Waldorfschulen, anthroposophischen Krankenhäusern, der biodynamischen Landwirtschaft und den weniger bekannten Dimensionen (Banken, Hochschulen, Stiftungen)... Die wissenschaftliche Forschung ist jedoch bislang schwach. Zwar liegen einige grundlegende Publikationen vor, an Detailforschung fehlt es jedoch überall. Der vorliegende Band enthält exemplarische Forschungen zu Waldorfpädagogik, Landwirtschaft, Steiners Philosophie, Kunst (Hilma af (...) Klint), Entwicklungen nach 1945 sowie Länderstudien (Bulgarien, Rumänien). Der Forschungsstand wird darüber hinaus durch bibliographische Informationen zu wichtigen Praxisfeldern sowie einen einleitenden Überblick über aktuelle Debatten dokumentiert. Damit wird Einstieg in die Anthroposophieforschung sowohl für akademische Forscher/-innen als auch für Interessenten der Praxisfelder erleichtert. Somit ermöglicht dieser Band auch eine Orientierung angesichts des Dschungels der weltanschaulich geprägten Literatur. (shrink)

Recent work in formal semantics suggests that the language system includes not only a structure building device, as standardly assumed, but also a natural deductive system which can determine when expressions have trivial truth-conditions (e.g., are logically true/false) and mark them as unacceptable. This hypothesis, called the `logicality of language', accounts for many acceptability patterns, including systematic restrictions on the distribution of quantifiers. To deal with apparent counter-examples consisting of acceptable tautologies and contradictions, the logicality of language is often paired (...) with an additional assumption according to which logical forms are radically underspecified: i.e., the language system can see functional terms but is `blind' to open class terms to the extent that different tokens of the same term are treated as if independent. This conception of logical form has profound implications: it suggests an extreme version of the modularity of language, and can only be paired with non-classical---indeed quite exotic---kinds of deductive systems. The aim of this paper is to show that we can pair the logicality of language with a different and ultimately more traditional account of logical form. This framework accounts for the basic acceptability patterns which motivated the logicality of language, can explain why some tautologies and contradictions are acceptable, and makes better predictions in key cases. As a result, we can pursue versions of the logicality of language in frameworks compatible with the view that the language system is not radically modular vis-a-vis its open class terms and employs a deductive system that is basically classical.

Bi-intuitionistic logic is the result of adding the dual of intuitionistic implication to intuitionistic logic. In this note, we characterize the expressive power of this logic by showing that the first order formulas equivalent to translations of bi-intuitionistic propositional formulas are exactly those preserved under bi-intuitionistic directed bisimulations. The proof technique is originally due to Lindstrom and, in contrast to the most common proofs of this kind of result, it does not use the machinery of neither saturated models nor elementary (...) chains. (shrink)

Lindström’s theorem obviously fails as a characterization of first-order logic without identity ( $\mathcal {L}_{\omega \omega }^{-} $ ). In this note, we provide a fix: we show that $\mathcal {L}_{\omega \omega }^{-} $ is a maximal abstract logic satisfying a weak form of the isomorphism property (suitable for identity-free languages and studied in [11]), the Löwenheim–Skolem property, and compactness. Furthermore, we show that compactness can be replaced by being recursively enumerable for validity under certain conditions. In the proofs, we (...) use a form of strong upwards Löwenheim–Skolem theorem not available in the framework with identity. (shrink)

The meaning that expressions take on particular occasions often depends on the context in ways which seem to transcend its direct effect on context-sensitive parameters. ‘Truth-conditional pragmatics’ is the project of trying to model such semantic flexibility within a compositional truth-conditional framework. Most proposals proceed by radically ‘freeing up’ the compositional operations of language. I argue, however, that the resulting theories are too unconstrained, and predict flexibility in cases where it is not observed. These accounts fall into this position because (...) they rarely, if ever, take advantage of the rich information made available by lexical items. I hold, instead, that lexical items encode both extension and non-extension determining information. Under certain conditions, the non-extension determining information of an expression e can enter into the compositional processes that determine the meaning of more complex expressions which contain e. This paper presents and motivates a set of type-driven compositional operations that can access non-extension determining information and introduce bits of it into the meaning of complex expressions. The resulting multidimensional semantics has the tools to deal with key cases of semantic flexibility in appropriately constrained ways, making it a promising framework to pursue the project of truth-conditional pragmatics.

This paper is a step toward showing what is achievable using non-classical metatheory—particularly, a substructural paraconsistent framework. What standard results, or analogues thereof, from the classical metatheory of first order logic can be obtained? We reconstruct some of the originals proofs for Completeness, Löwenheim-Skolem and Compactness theorems in the context of a substructural logic with the naive comprehension schema. The main result is that paraconsistent metatheory can ‘re-capture’ versions of standard theorems, given suitable restrictions and background assumptions; but the shift (...) to non-classical logic may recast the meanings of these apparently ‘absolute’ theorems.

This paper is devoted to the problem of existence of saturated models for first-order many-valued logics. We consider a general notion of type as pairs of sets of formulas in one free variable that express properties that an element of a model should, respectively, satisfy and falsify. By means of an elementary chains construction, we prove that each model can be elementarily extended to a $\kappa $-saturated model, i.e. a model where as many types as possible are realized. In order (...) to prove this theorem we obtain, as by-products, some results on tableaux and their consistency and satisfiability and a generalization of the Tarski–Vaught theorem on unions of elementary chains. Finally, we provide a structural characterization of $\kappa $-saturation in terms of the completion of a diagram representing a certain configuration of models and mappings. (shrink)

O artigo – desde uma perspectiva da educação como direito humano universal que reconhece a diversidade – realiza um recorrido panorâmico por uma série de dimensões da educação intercultural no ensino superior do Chile, especialmente universitária, discute criticamente a situação atual da interculturalização na universidade – entendida genericamente – e conclui com algumas perguntas que podem orientar pesquisas ou decisões que levem a que o ensino superior considere os direitos indígenas, permita a expressão de sua cultura, promova a interculturalidade, forme (...) os técnicos e profissionais que requerem o desenvolvimento da sociedade e das comunidades e enriqueça a docência e a ciência com outros paradigmas de conhecimento. Desse modo, que reconheça e valide a interculturalidade e os aportes das culturas indígenas a sua identidade, formação e produção de conhecimento. Trata das comunidades e dos estudantes indígenas em geral, mas aprofunda a situação desde o povo mapuche, embasando-se em projetos de pesquisa e desenvolvimento e em experiências em e desde a Região da Araucanía. A proposta se centra na ideia de que o direito à educação, desde a lei e inconstitucionalidade atual, se centra no sistema escolar formal de ensino básico e médio e não considera a educação superior ou a um sistema de educação continuado como direito universal, no qual poderia se especificar uma condição especial aos estudantes indígenas. Por isso, hoje se luta pela igualdade de oportunidades de inclusão entre indígenas e não indígenas. Palavras-chave: Ensino Superior. Interculturalidade. Cultura mapuche. (shrink)

Under a proper translation, the languages of propositional (and quantified relevant logic) with an absurdity constant are characterized as the fragments of first order logic preserved under (world-object) relevant directed bisimulations. Furthermore, the properties of pointed models axiomatizable by sets of propositional relevant formulas have a purely algebraic characterization. Finally, a form of the interpolation property holds for the relevant fragment of first order logic.

We generalize the notion ofconsequence relationstandard in abstract treatments of logic to accommodate intuitions ofrelevance. The guiding idea follows theuse criterion, according to which in order for some premises to have some conclusion(s) as consequence(s), the premises must each beusedin some way to obtain the conclusion(s). This relevance intuition turns out to require not just a failure of monotonicity, but also a move to considering consequence relations as obtaining betweenmultisets. We motivate and state basic definitions of relevant consequence relations, both (...) in single conclusion (asymmetric) and multiple conclusion (symmetric) settings, as well as derivations and theories, guided by the use intuitions, and prove a number of results indicating that the definitions capture the desired results (at least in many cases).

Despite recognizing the importance of impact investing in combating complex societal challenges, researchers have yet to examine the capacity of the field to address systemic inequality. While impact investments are intended to benefit vulnerable stakeholders, the voices of those stakeholders are generally overlooked in the design and implementation of such investments. To resolve this oversight, we theorize how the fields’ design—through its tools, organizations, and field-level bodies—influences its capacity to address inequality by focusing on the concept of giving voice, which (...) we define as the inclusive participation of vulnerable stakeholders in decision-making processes. We build from stakeholder engagement research to show how the design of impact investing can address inequality using three illustrative cases: social impact bonds, impact investing funds, and national advisory boards. We conclude with a discussion of how the ethical decision of giving voice to vulnerable stakeholders will determine the capacity of the field to address inequality, as well as provide implications for future research and practice.

According to Kratzer’s influential account of epistemic must and might, these operators involve quantification over domains of possibilities determined by a modal base and an ordering source. Recently, this account has been challenged by invoking contexts of ‘epistemic tension’: i.e., cases in which an assertion that must\ is conjoined with the possibility that \, and cases in which speakers try to downplay a previous assertion that must\, after finding out that \. Epistemic tensions have been invoked from two directions. Von (...) Fintel and Gillies :351–383, 2010) propose a return to a simpler modal logic-inspired account: must and might still involve universal and existential quantification, but the domains of possibilities are determined solely by realistic modal bases. In contrast, Lassiter :117–163, 2016), following Swanson, proposes a more revisionary account which treats must and might as probabilistic operators. In this paper, we present a series of experiments to obtain reliable data on the degree of acceptability of various contexts of epistemic tension. Our experiments include novel variations that, we argue, are required to make progress in this debate. We show that restricted quantificational accounts à la Kratzer fit the overall pattern of results better than either of their recent competitors. In addition, our results help us identify the key components of restricted quantificational accounts, and on that basis propose some refinements and general constraints that should be satisfied by any account of the modal auxiliaries.

In this note we study a counterpart in predicate logic of the notion of logical friendliness, introduced into propositional logic in [15]. The result is a new consequence relation for predicate languages with equality using first-order models. While compactness, interpolation and axiomatizability fail dramatically, several other properties are preserved from the propositional case. Divergence is diminished when the language does not contain equality with its standard interpretation.

We show that propositional intuitionistic logic is the maximal abstract logic satisfying a certain form of compactness, the Tarski union property, and preservation under asimulations.

Este trabajo pretende preguntarse si, a pesar del “silencio” de Heidegger ante la teoría de los géneros poéticos de Hölderlin, no es esta misma teoría, y especialmente el poema lírico que caracteriza a la modernidad, la cuestión en la cual se apoya Heidegger para fundamentar su “historia del ser”, de modo que la noción fuerte de _historia _que se maneja en su obra y finalmente el término marcado _das Ereignis _estaría en sintonía con los “trayectos poéticos” que Hölderlin teoriza.

The logicality of language is the hypothesis that the language system has access to a ‘natural’ logic that can identify and filter out as unacceptable expressions that have trivial meanings—that is, that are true/false in all possible worlds or situations in which they are defined. This hypothesis helps explain otherwise puzzling patterns concerning the distribution of various functional terms and phrases. Despite its promise, logicality vastly over-generates unacceptability assignments. Most solutions to this problem rest on specific stipulations about the properties (...) of logical form—roughly, the level of linguistic representation which feeds into the interpretation procedures—and have substantial implications for traditional philosophical disputes about the nature of language. Specifically, contextualism and semantic minimalism, construed as competing hypotheses about the nature and degree of context-sensitivity at the level of logical form, suggest different approaches to the over-generation problem. In this paper, I explore the implications of pairing logicality with various forms of contextualism and semantic minimalism. I argue that to adequately solve the over-generation problem, logicality should be implemented in a constrained contextualist framework. (shrink)

Para Habermas, “el fenómeno que nos inquieta es la imprecisión de lasfronteras entre la naturaleza que somos y la dotación orgánica que nosdamos” (Habermas, 2002, pág. 37).

Seexpondrá qué procesos culturales, además de la “naturaleza”, han estadodándonos tanto cuerpo físico como cuerpo social; por lo tanto, la fronterase ha desvanecido. Urge entonces preguntarse si bajo (...) estas circunstancias seestaría modificando, en sus términos, la autocomprensión ética de la especie. (shrink)

This paper defines a Sahlqvist fragment for relevant logic and establishes that each class of frames in the Routley-Meyer semantics which is definable by a Sahlqvist formula is also elementary, that is, it coincides with the class of structures satisfying a given first order property calculable by a Sahlqvist-van Benthem algorithm. Furthermore, we show that some classes of Routley-Meyer frames definable by a relevant formula are not elementary.

How are biases encoded in our representations of social categories? Philosophical and empirical discussions of implicit bias overwhelmingly focus on salient or statistical associations between target features and representations of social categories. These are the sorts of associations probed by the Implicit Association Test and various priming tasks. In this paper, we argue that these discussions systematically overlook an alternative way in which biases are encoded, that is, in the dependency networks that are part of our representations of social categories. (...) Dependency networks encode information about how features in a conceptual representation depend on each other. This information determines the degree of centrality of a feature for a conceptual representation. Importantly, centrally encoded biases systematically disassociate from those encoded in salient-statistical associations. Furthermore, the degree of centrality of a feature determines its cross-contextual stability: in general, the more central a feature is for a concept, the more likely it is to survive into a wide array of cognitive tasks involving that concept. Accordingly, implicit biases that are encoded in the central features of concepts are predicted to be more resilient across different tasks and contexts. As a result, the distinction between centrally encoded and salient-statistical biases has important theoretical and practical implications. (shrink)

ABSTRACTDo truth tables—the ordinary sort that we use in teaching and explaining basic propositional logic—require an assumption of consistency for their construction? In this essay we show that truth tables can be built in a consistency-independent paraconsistent setting, without any appeal to classical logic. This is evidence for a more general claim—that when we write down the orthodox semantic clauses for a logic, whatever logic we presuppose in the background will be the logic that appears in the foreground. Rather than (...) any one logic being privileged, then, on this count partisans across the logical spectrum are in relatively similar dialectical positions. (shrink)

Na carta 12 de sua correspondência, Spinoza expõe sua con-cepção do infinito atual. Nesse contexto, ele desenvolve certos aspectos de sua ontologia de imanência, assim como o significado que para ele possuem os conceitos de eternidade, duração e tempo. Este texto tor-na-se então central para qualquer estudioso da questão da temporalidade em Spinoza. Nosso autor distancia-se da perspectiva cartesiana que, na mesma questão, expôs —não sem críticas— nos Princípios da Filosofia Cartesiana e nos Pensamentos Metafísicos, ambos publicados em 1663. Neste (...) artigo nos propomos estudar a distinção entre duração e tempo, para sublinhar a perspectiva propriamente spinozista da carta 12, e assim mostrar o significado que para Spinoza esses conceitos possuem no con-texto de uma discussão científica sobre o infinito atual.

We provide a sucient frame-theoretic condition for a super bi-intuitionistic logic to have Maksimova's variable separation property. We conclude that bi-intuitionistic logic enjoys the property. Furthermore, we offer an algebraic characterization of the super-bi-intuitionistic logics with Maksimova's property.

Stemming from the works of Petr Hájek on mathematical fuzzy logic, graded model theory has been developed by several authors in the last two decades as an extension of classical model theory that studies the semantics of many-valued predicate logics. In this paper we take the first steps towards an abstract formulation of this model theory. We give a general notion of abstract logic based on many-valued models and prove six Lindström-style characterizations of maximality of first-order logics in terms of (...) metalogical properties such as compactness, abstract completeness, the Löwenheim–Skolem property, the Tarski union property, and the Robinson property, among others. As necessary technical restrictions, we assume that the models are valued on finite MTL-chains and the language has a constant for each truth-value. (shrink)
