We study a logic for deontic necessity and sufficiency, as originally proposed in van Benthem :36–41, 1979). Building on earlier work in modal logic, we provide a sound and complete axiomatization for it, consider some standard extensions, and study other important properties. After that, we compare this logic to the logic of “obligation as weakest permission” from Anglberger et al. :807–827, 2015).

Artifacts are probably our most obvious everyday encounter with technology. Therefore, a good understanding of the nature of technical artifacts is a relevant part of technological literacy. In this article we draw from the philosophy of technology to develop a conceptualization of technical artifacts that can be used for educational purposes. Furthermore we report a small exploratory empirical study to see to what extent teachers’ intuitive ideas about artifacts match with the way philosophers write about the nature of artifacts. Finally, (...) we suggest a teaching and learning strategy for improving teachers’ concepts of technical artifacts through practical activities. (shrink)

We study classical modal logics with pooling modalities, i.e. unary modal operators that allow one to express properties of sets obtained by the pointwise intersection of neighbourhoods. We discuss salient properties of these modalities, situate the logics in the broader area of modal logics, establish key properties concerning their expressive power, discuss dynamic extensions of these logics and provide reduction axioms for the latter.

This article discusses the proof theory, semantics and meta-theory of a class of adaptive logics, called hierarchic adaptive logics. Their specific characteristics are illustrated throughout the article with the use of one exemplary logic HKx, an explicans for reasoning with prioritized belief bases. A generic proof theory for these systems is defined, together with a less complex proof theory for a subclass of them. Soundness and a restricted form of completeness are established with respect to a non-redundant semantics. It is (...) shown that all hierarchic adaptive logics are reflexive, have the strong reassurance property and that a subclass of them is a fixed point for a broad class of premise sets. Finally, they are compared to a different yet related class of adaptive logics. (shrink)

We establish completeness and the finite model property for logics featuring the pooling modalities that were introduced in Van De Putte and Klein. The definition of our canonical models combines standard techniques with a so-called “puzzle piece construction”, which we first illustrate informally. After that, we apply it to the weakest classical logics with pooling modalities and investigate the technique’s potential for the axiomatization of stronger logics, obtained by imposing well-known frame conditions on the models.

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical disagreement’. Chapters 1 and (...) 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

Default logic has been a very active research topic in artificial intelligence since the early 1980s, but has not received as much attention in the philosophical literature thus far. This paper shows one way in which the technical tools of artificial intelligence can be applied in contemporary epistemology by modeling a paradigmatic case of deep disagreement using default logic. In §1 model-building viewed as a kind of philosophical progress is briefly motivated, while §2 introduces the case of deep disagreement we (...) aim to model. On the heels of this, §3 defines our formal framework, viz., a refined Horty-style default logic. §4 then uses the framework to model deep disagreement, and finally §5 provides a critical discussion of the result.

We study original position arguments in the context of social choice under ignorance. First, we present a general formal framework for such arguments. Next, we provide an axiomatic characterization of social choice rules that can be supported by original position arguments. We illustrate this characterization in terms of various well-known social choice rules, some of which do and some of which do not satisfy the axioms in question. Depending on the perspective one takes, our results can be used to argue (...) against certain rules, against Rawlsian theories of procedural fairness, or in support of richer, multidimensional models of individual choice.

This paper studies the properties of eight semantic consequence relations defined from a Tarski-logic L and a preference relation ≺. They are equivalent to Shoham’s so-called preferential entailment for smooth model structures, but avoid certain problems of the latter in non-smooth configurations. Each of the logics can be characterized in terms of what we call multi-selection semantics. After discussing this type of semantics, we focus on some concrete proposals from the literature, checking a number of meta-theoretic properties and elaborating on (...) their intuitive motivation. As it turns out, many of their meta-properties only hold in case ≺ is transitive. To tackle this problem, we propose slight modifications of each of the systems, showing the resulting logics to behave better at the intuitive level and in metatheoretic terms, for arbitrary ≺.

We study the logic of neighbourhood models with pointwise intersection, as a means to characterize multi-modal logics. Pointwise intersection takes us from a set of neighbourhood sets Ni (one for each member i of a set G used to interpret the modality □) to a new neighbourhood set NG, which in turn allows us to interpret the operator □G Here, X is in the neighbourhood for G if and only if X equals the intersection of some Y {Yi | Yi (...) ∈G}. We show that the notion of pointwise intersection has various applications in epistemic and doxastic logic, deontic logic, coalition logic, and evidence logic. We then establish sound and strongly complete axiomatizations for the weakest logic characterized by pointwise intersection and for a number of variants, using a new and generally applicable technique for canonical model construction.

Validated self-report measures of post-stroke fatigue are lacking. The Dutch Multifactor Fatigue Scale (DMFS) was translated into Danish, and response process evidence of validity was evaluated. DMFS consists of 38 Likert-rated items distributed on five subscales: Impact of fatigue (11 items), Signs and direct consequences of fatigue (9), Mental fatigue (7), Physical fatigue (6), and Coping with fatigue (5). Response processes to DMFS were investigated using a Three-Step Test-Interview (TSTI) protocol, and data were analyzed using Framework Analysis. Response processes were (...) indexed on the following categories: (i) “congruent,” response processes were related to the subscale construct; (ii) “incongruent,” response processes were not related to the subscale construct; (iii) “ambiguous,” response processes were both congruent and incongruent or insufficient to evaluate congruency; and (iv) “confused,” participants did not understand the item. Nine adults were recruited consecutively 10–34 months post-stroke (median = 26.5) at an outpatient brain injury rehabilitation center in 2019 [five females, mean age = 55 years (SD= 6.3)]. Problematic items were defined as <50% of response processes being congruent with the intended construct. Of the 38 items, five problematic items were identified, including four items of Physical fatigue and one of Mental fatigue. In addition, seven items posed various response difficulties to some participants due to syntactic complexity, vague terms, a presupposition, and a double-barrelled statement. In conclusion, findings elucidate the interpretative processes involved in responding to DMFS post-stroke, strengthen the evidence base of validity, and guide revisions to mitigate potential problems in item performance.

In, a deontic logic is proposed which explicates the idea that a formulaφis obligatory if and only if it is the weakest permission. We give a sound and strongly complete, Hilbert style axiomatization for this logic. As a corollary, it is compact, contradicting earlier claims from Anglbergeret al.. In addition, we prove that our axiomatization is equivalent to Anglberger et al.’s infinitary proof system, and show that our results are robust w.r.t. certain changes in the underlying semantics.

En 2007, le philosophe danois Frederik Stjernfelt a donné une nouvelle vigueur aux études sur les diagrammes en publiant son opus majeur Diagrammatology. Ce terme a acquis l’extension d’une sous-discipline à part entière à l’intérieur des études sémiotiques. La diagrammatologie fédère aujourd’hui des recherches venues des sciences cognitives aussi bien que du post-structuralisme, des mathématiques et des études littéraires. Frederik Stjernfelt explique comment la diagrammatologie résulte pour lui d’une redéfinition de certains concepts fondamentaux (ceux de signe, de proposition (...) et de diagramme au premier chef) amorcée par le père du pragmatisme, Charles S. Peirce. (shrink)

Theodor W. Adornos Denken war Zeit seines Lebens von einem ebenso fruchtbaren wie zwiespältigen Verhältnis zu den Medien durchdrungen. Dabei verstand er es, seine gesellschaftskritischen Überlegungen an ihnen ebenso zu schärfen wie sie für die Vermittlung seiner Analysen an ein breites Publikum zu nutzen. Auch wenn er diese ambivalente Haltung an damaligen Medien entwickelte, erweist sich der Ansatz als vielversprechend, sie an der heutigen Medienlandschaft in ihrem Einfluss auf Gesellschaft, Politik und Kultur zu erproben. Die Fragen nach der Relevanz von (...) Adornos kritischer Theorie in der zeitgenössischen Reflexion der digitalen Kultur sowie nach der Bedeutung seiner Medienkritik für Philosophie, Kunstwissenschaft und Kulturtheorie der letzten Jahrzehnte stehen im Mittelpunkt dieses Bandes. Unterschiedliche Positionen und methodologische Ansätze zu Adornos intellektuellem Nachlass öffnen neue interdisziplinäre Perspektiven auf aktuelle Medienphänomene und kulturelle Prozesse und setzen die Tradition einer philosophisch informierten und soziologisch fundierten Medienkritik fort. -/- Mit Beiträgen von Sarah Bianchi, Christian Fuchs, Samir Gandesha, Henrik Holm, Sulgi Lie, Stefano Marino, Tyrus Miller, Judith-Frederike Popp, Ulrike Ramming, Martin Ritter, Rolando Vitali, Lioudmila Voropai und Florian Wobser.

Der vorliegende Aufsatz widmet sich der Charakterisierung von Methoden als Bezugspunkt der Designforschung aus einer rationalitätstheoretischen Perspektive. Im Fokus steht dabei zum einen die Überlegung, wie der Einsatz von kreativen und wissenschaftlichen Methoden den Gestaltungsprozess systematisiert und rationalisiert. Zum anderen geht es darum, wie die spezifischen Qualitäten von Designprozessen etablierte Verständnisse sowohl von Wissenschaft und Forschung als auch von Rationalität als solcher herausfordern. Mit Bezug auf konkrete Beispiele für Forschungsprojekte wird die Möglichkeit erkundet, inwieweit die pragmatisch formende Verhandlung eines methodischen (...) Vorgehens Designforschung mit der Kapazität ausstattet, einen Maßstab für selbstkritische Forschungspraxis zu aktualisieren. Es wird gezeigt, dass dieser Maßstab Implikationen für die philosophische Bestimmung gestalterischer und wissenschaftlicher Rationalität bereithält. Eine zentrale Rolle kommt dabei den externen und internen Grenzgebieten von Vernünftigkeit zu. (shrink)

Den filosofiske position konsekventialisme er ofte genstand for debat i filosofikredse, men alt for hyppigt opstår der misforståelser blandt de involverede, fordi de ikke er eksplicitte, hvad grundantagelser og væsentlige distinktioner angår. Denne korte artikel vil give en approksimation af, hvad der forstås ved konsekventialisme på et generisk niveau. Målet med artiklen er at klargøre nogle af de grundantagelser og distinktioner, som konsekventialister ofte benytter i deres teoridannelse, og som bør holdes for øje i ønsket om en frugtbar debat.

A première vue, Friedrich Nietzsche et Cesare Pavese n'ont rien en commun. Et pourtant! Tous deux sont orphelins de père. Tous deux ont grandi dans un entourage exclusivement féminin. Tous deux n'ont jamais su se faire aimer d'une femme. Tous deux sont également poètes. Tous deux ont eu une vie brève, solitaire et émouvante. Et tous deux ont amplement écrit sur Turin, sur son atmosphère si parfaitement " psychologique ". De cette ville, qui fut un temps la capitale de l'Italie, (...) Nietzsche n'en a dit que l'abord exaltant, aristocratique et baroque, tandis que Pavese en a recraché toute la tristesse, avec ses vastes quartiers industriels, ses usines qui noircissent le ciel, ses ouvriers exténués. C'est à Turin que Nietzsche perd définitivement la raison. Il a quarante-quatre ans. Et c'est à Turin que Pavese se suicide dans une chambre d'hôtel. Il a quarante-deux ans. Le philosophe allemand meurt le 25 août 1900. L'écrivain piémontais meurt le 26 août 1950 - un demi-siècle plus tard, à un jour près. En cherchant des rapprochements entre ces deux artistes exceptionnels, l'auteur pénètre dans leur drame intime, dans les blessures inguérissables de leur enfance ; et l'on revit les derniers instants tragiques qui les conduisirent à la folie et à la mort. Ce livre, s'il est empreint de gravité, est avant tout une rêverie faite de détours et de coïncidences. Les murs de Turin y transpirent. Ils parlent. Et il fallait bien près de trois cents dessins pour faire entendre ces voix. (shrink)

Nietzsche ne peut que se tuer lui-même pour tuer son père ; et, en se tuant, il ne fait que tuer un père déjà mort. Est-ce à dire que Nietzsche va mourir de ne pouvoir tuer son père?

In Critique of Judgment, Kant introduces a foundational theme in modern aesthetics by identifying the judgment of taste as a particular mode of attention. In distinction to the mode of attention in mundane experience that works by determining how an intuition can be subsumed under a concept, aesthetic attention celebrates the pleasure associated with the “unison in the play of the powers of the mind” confronted with “the manifold in a thing.” Aesthetic attention, in other words, is an aesthetic subject’s (...) attention to itself and to the pleasures derived from flexing the power of imagination. In this respect, Kant’s aesthetics reaffirms its cartesian core, the primordial positing of the thinking and reflective I as the necessary preposition for experience. This strict distribution of attention toward the secure epistemological architecture of object and subject seems to vacillate, however, in Kant’s brief discussion of artworks as purveyors of “aesthetic ideas.” This article discusses the de-limitation of attention instigated by the aesthetic idea. The aesthetic idea is associated with the artwork as an object, but it immediately transgresses the limits of the object through an array of analogical instantiations of “spirit.” On the other hand, aesthetic ideas are subjectively appreciated, but this appreciation similarly transgresses subjective cognition in an inexhaustible ramification of associative thinking. Developing these characteristics of the “aesthetic idea,” the article proposes to excavate from Critique of Judgment a mode of aesthetic sensibility that eventually challenges the Cartesian architecture of subject and object and thus reposits aesthetics in a field of relational interdependency.

Precisamos repensar a nossa abordagem quanto à proteção da privacidade na internet. Atualmente, os formuladores de políticas vêm se aprofundando na ideia de consentimento informado como um meio para proteger a privacidade. Por exemplo, em diversos países, as empresas são obrigadas por lei a obter o consentimento de um indivíduo antes de fazer uso dos seus dados; com base nessas requisitos de consentimento informado, a lei tem por objetivo empoderar as pessoas a fazerem escolhas de privacidade tendo em vista os (...) seus melhores interesses. No entanto, estudos comportamentais colocam em cheque a eficácia desta abordagem de empoderamento como um meio para proteger a privacidade. Este artigo defende uma abordagem conjunta de proteção e empoderamento dos indivíduos para aprimorar a proteção da privacidade. Este artigo aborda problemas práticos do consentimento informado como um meio para proteger a privacidade, e ilustra problemas com os atuais regulamentos de proteção à privacidade dos dados, concernentes à segmentação comportamental. Primeiramente, discutem-se os problemas de privacidade relativos à segmentação comportamental, e o papel central do consentimento informado ao abrigo da lei de proteção à privacidade. Em seguida, enfatizam-se os problemas práticos referentes ao consentimento informado. Por fim, o artigo argumenta que os formuladores de políticas devem dar mais atenção aos regulamentos que protegem as pessoas, e menos aos que as empoderam. INFORMED CONSENT: WE CAN DO BETTER TO DEFEND PRIVACYAbstractWe need to rethink our approach to defend privacy on the internet. Currently, policymakers focus heavily on the idea of informed consent as a means to defend privacy. For instance, in many countries the law requires firms to obtain an individual’s consent before they use data about her. With such informed consent requirements, the law aims to empower people to make privacy choices in their best interests. But behavioural studies cast doubt on this approach’s effectiveness, as people tend to click OK to almost any request they see on their screens. To improve privacy protection, this article argues for a combined approach of protecting and empowering the individual. (shrink)

Cette introduction présente et contextualise les articles publiés dans la section spéciale dont le but est d’analyser l’interprétation de la pensée hellénistique chez les philosophes continentaux très influents tels que : Agamben, Arendt, Blumenberg, Foucault, Heidegger et Stiegler. Les articles prêtent une attention particulière à trois directions de recherche. Ils examinent tout d’abord l’influence de la pensée hellénistique sur ces auteurs et la façon dont ils ont interprété, utilisé et mésinterprété l’héritage des philosophies hellé-nistiques. Deuxièmement, les articles analysent les hypothèses (...) in-terprétatives et les préjugés qui ont caractérisé ces interprétations. Enfin, ils nous permettent de comprendre plus clairement pourquoi plusieurs philosophes continentaux se sont intéressés à la philosophie ancienne. Les rédacteurs invités résument les conclusions pro-visoires de cette section spéciale en soulignant que les interprétations continentales de la pensée hellénistique représentent un thème particulièrement intéressant dans le cadre de la recherche historico-philosophique actuelle.

While it is well known that Plutarch’s De facie in orbe lunae was a major source of inspiration for Galileo’s Sidereus nuncius, its influence on his Dialogo sopra i due massimi sistemi del mondo, and especially on his views on gravity, has not been sufficiently explored. This essay offers the first systematic comparison of Plutarch’s and Galileo’s accounts of gravity by focusing on four themes: the thought experiment of a stone falling in a tunnel passing through the center of the (...) Earth; the account of gravity as a tendency to unite with the whole; the view that the Moon is a separate center of attraction; and the impossibility of attraction by an incorporeal point. The essay analyzes the role that these themes play in De facie and in the Dialogo, trying to understand how Galileo appropriated, reworked, and expanded on Plutarch’s views. (shrink)

Artiklen perspektiverer på den almene pædagogiks aktuelle, pressede tilstand, i lyset af de centrale, transnationale udviklingstendenser inden for uddannelsesstyring der har gjort sig gældende de sidste ca. 25-30 år. Dette gøres, ved at tage afsæt i de såkaldte antinomier, som en række pædagogiske forskere har forholdt sig til som definerende for moderne pædagogik. Denne tematik blevet sat på dagsordenen af aktuelle uddannelsesforskere som bl.a. Alexander von Oettingen; Michael Uljens; Lars Løvlie; Gert Biesta, Birgit Schaffar og Dietrich Benner. Oettingen ser nærmere (...) bestemt spørgsmålet om pædagogisk professionalitet som spaltet i fire antinomiske paradokser, der angår Rationalisering ; Pluralisering ; Individualisering og Civilisering. Disse pædagogiske paradoksaliteter har en rod bl.a. hos Kant, Rousseau og Herbart. Artiklen søger gennem fokusering af sådanne pædagogiske antinomier eller paradokser at vise, hvorledes den transnationale uddannelsesrevolution de sidste 25-30 år har udtyndet den almenpædagogiske undermuring af begreberne: I. professionalitet, II. læring, III. autenticitet og IV. dannelse. Dermed fokuseres de almenpædagogiske problemstillinger der kendetegner disse fire begreber. Dette gøres for at vise, hvorledes den transnationale uddannelsesstyring i dette lys udgør en bekymrende afvikling eller sammenklapning af pædagogikkens almene grundtræk. (shrink)

In this paper, an overview is presented over the complex phenomenon of artistic authorship against the background of its historical, medial and social conditions before discussing some thoughts about the similarities and differences of artistic and aesthetic authorship as well as their implications for conceptions of subjectivity.

That Cn. Pompeius Magnus (cos. 70, II 55, III 52) was charged with the Roman cura annonae in September 57 is a fact quite well known to Roman historians and all interested in the history of the late Republic. Although Pompeius’ grain commission in many respects represented a novel development, relatively few have bothered to study the fine detail of what happened to be the third and final extraordinary proconsulship of his remarkable career, signifying that several important questions remain largely (...) unanswered1. After a brief discussion of the political context of the late summer of 57, this study therefore endeavours to cast a new light on his powers under the constitutive statute, the issue of the terminus of his tenure as superintendent of the grain supply, and its wider historical ramifications.

_Abduction of generalizations_ is the process in which explanatory hypotheses are formed for an observed, yet puzzling generalization such as ``pineapples taste sweet" or ``rainbows appear when the sun breaks through the rain". This phenomenon has received little attention in formal logic and philosophy of science. The current paper remedies this lacuna by first giving an overview of some general characteristics of this process, elaborating on its ubiquity in scientific and daily life reasoning. Second, the adaptive logic $\LAG$ is presented (...) to explicate this process formally. (shrink)

This paper presents eight (previously unpublished) adaptive logics for belief revision, each of which define a belief revision operation in the sense of the AGM framework. All these revision operations are shown to satisfy the six basic AGM postulates for belief revision, and Parikh's axiom of Relevance. Using one of these logics as an example, we show how their proof theory gives a more dynamic flavor to belief revision than existing approaches. It is argued that this turns belief revision (that (...) obeys Relevance) into a more natural undertaking, where analytic steps are performed only as soon as they turn out to be necessary in order to uphold certain beliefs.

We argue and demonstrate that an emphasis on outperforming others may lead to perverse effects. Four studies show that assigning other-referenced performance goals, relative to self-referenced mastery goals, may lead to more interpersonally harmful behavior in an information exchange context. Results of Study 1 indicate that assigned performance goals lead to stronger thwarting behavior and less accurate information giving to an exchange partner than assigned mastery goals. Similarly, in Study 2 performance goal individuals more subtly deceived highly competent opponents relative (...) to lowly competent opponents, who received more blatant treatment. Finally, Studies 3 and 4 show in methodologically complementary ways that tactical deception considerations may account for the interpersonally harmful behavior of performance goal individuals.
