Dynamic Epistemic Logic (DEL) deals with the representation and the study in a multi-agent setting of knowledge and belief change. It can express in a uniform way epistemic statements about: 1. what is true about an initial situation 2. what is true about an event occurring in this situation 3. what is true about the resulting situation after the event has occurred. We axiomatize within the DEL framework what we can infer about (iii) given (i) and (ii). Given three formulas (...) φ,φ' and φ" describing respectively (i), (ii) and (iii), we also show how to build a formula φ ? φ' which captures all the information which can be inferred about (iii) from φ and φ'. We show how our results extend to other modal logics than K. In our proofs and definitions, we resort to a large extent to the normal form formulas for modal logic originally introduced by Kit Fine. In a companion paper (Aucher, 2012), we axiomatize what we can infer about (ii) given (i) and (iii), and what we can infer about (i) given (ii) and (iii), and show how to build two formulas φ ? φ" and φ' ? φ" which capture respectively all the information which can be inferred about (ii) from φ and φ", and all the information which can be inferred about (i) from φ' and φ".

After observing that the truth conditions of connectives of non–classical logics are generally defined in terms of formulas of first–order logic, we introduce ‘protologics’, a class of logics whose connectives are defined by arbitrary first–order formulas. Then, we introduce atomic and molecular logics, which are two subclasses of protologics that generalize our gaggle logics and which behave particularly well from a theoretical point of view. We also study and introduce a notion of equi-expressivity between two logics based on different classes (...) of models. We prove that, according to that notion, every pure predicate logic with \ variables and constants is as expressive as a predicate atomic logic, some sort of atomic logic. Then, we prove that the class of protologics is equally expressive as the class of molecular logics. That formally supports our claim that atomic and molecular logics are somehow ‘universal’. Finally, we identify a subclass of molecular logics that we call predicate molecular logics and which constitutes its representative core: every molecular logic is as expressive as a predicate molecular logic.

Representing an epistemic situation involving several agents obviously depends on the modeling point of view one takes. We start by identifying the types of modeling points of view which are logically possible. We call the one traditionally followed by epistemic logic the perfect external approach, because there the modeler is assumed to be an omniscient and external observer of the epistemic situation. In the rest of the paper we focus on what we call the internal approach, where the modeler is (...) one of the agents involved in the situation. For this approach we propose and axiomatize a logical formalism based on epistemic logic. This leads us to formalize some intuitions about the internal approach and about its connections with the external ones. Finally, we show that our internal logic is decidable and PSPACE-complete.

In update logic as studied by Baltag, Moss, Solecki and van Benthem, little attention is paid to the interpretation of an action by an agent, which is just assumed to depend on the situation. This is actually a complex issue that nevertheless complies to some logical dynamics. In this paper, we tackle this topic. We also deal with actions that change propositional facts of the situation. In parallel, we propose a formalism to accurately represent an agent's epistemic state based on (...) hyperreal numbers. In that respect, we use infinitesimals to express what would surprise the agents (and by how much) by contradicting their beliefs. We also use a subjective probability to model the notion of belief. It turns out that our probabilistic update mechanism satisfies the AGM postulates of belief revision. (shrink)

In epistemic logic, some axioms dealing with the notion of knowledge are rather convoluted and difficult to interpret intuitively, even though some of them, such as the axioms.2 and.3, are considered to be key axioms by some epistemic logicians. We show that they can be characterized in terms of understandable interaction axioms relating knowledge and belief or knowledge and conditional belief. In order to show it, we first sketch a theory dealing with the characterization of axioms in terms of interaction (...) axioms in modal logic. We then apply the main results and methods of this theory to obtain specific results related to epistemic and doxastic logics. (shrink)

Knowledge based privacy policies are more declarative than traditional action based ones, because they specify only what is permitted or forbidden to know, and leave the derivation of the permitted actions to a security monitor. This inference problem is already non trivial with a static privacy policy, and becomes challenging when privacy policies can change over time. We therefore introduce a dynamic modal logic that permits not only to reason about permitted and forbidden knowledge to derive the permitted actions, but (...) also to represent explicitly the declarative privacy policies together with their dynamics. The logic can be used to check both regulatory and behavioral compliance, respectively by checking that the permissions and obligations set up by the security monitor of an organization are not in conflict with the privacy policies, and by checking that these obligations are indeed enforced.

La réflexion philosophique, dont l'ouverture à l'univers dans lequel nous nous découvrons - avec une acuité proportionnelle à un étonnement renouvelé - n'a pas de limites, n'en est que plus tributaire des sciences et des techniques, des arts et de multiples activités qui régissent plus ou moins fructueusement notre expérience. Or, au sein des sciences humaines, privilégiées pour éclairer une condition que nous ne saurions cesser d'interpréter, peu d'oeuvres du dernier siècle auront enrichi en le précisant notre être-au-monde, comme la (...) théorie linguistique de Gustave Guillaume, assez solitaire, et les recherches multiformes de Jean Piaget - où la psychologie de l'enfant a souvent occulté la visée épistémologique et son enracinement biologique (cf Biologie et connaissance, 1967) et ses prolongements pédagogiques, voire éthiques. Le Cinquantenaire et le Trentenaire de leur disparition appelaient un hommage d'autant plus impératif qu'ils sont restés marginaux ou ignorés dans les milieux philosophiques, malgré la centralité de leurs élucidations. Leur commune orientation génétique et structurale n'ayant suscité aucun échange, pendant la contemporanéité de publications d'un tiers de siècle (1923-1960), mesurer leur complémentarité s'impose d'autant plus. S'ils peuvent aider à repenser la condition humaine, c'est qu'ils auront contribué à dissiper le "mystère de la pensée". L'un cherchant à habiliter les caractères systématique et cinétique des langues, irremplaçables moyens de penser ; l'autre dans un vis-à-vis cognitif et opératoire de Freud, en relavant sur les plans épistémologique et logique, notamment, l'élan révolutionnaire de la seconde modernité, autour de l'évolutionnisme. Mais les thèmes majeurs du constructivisme, du schème et de la symbolisation - et plus largement du temps et du langage - auront sans doute aidé à spécifier les mutations autorisées par la révolution critique. Entre l'Instant du je parle et un décentrement exigible pratiquement (éthique) comme théoriquement (épistémique), c'est bien la condition humaine dans son ensemble qui est concernée. Si repenser cette Condition s'impose en permanence, il importe de ne pas manquer des oeuvres qui, par-delà toute mode, proposent à notre expérience des fondations résistant à d'inéluctables vicissitudes.

The confrontations of stakeholder visions about agriculture and food production has become a focal point in the public sphere, coinciding with a diversification of agrifood models. This study analyzes the debates stemming from the coexistence of these models, particularly during the initial term of neoliberal-centrist Emmanuel Macron’s presidency in France. Employing collective monitoring from 2017 to 2021, a corpus of 958 online news and blog articles was compiled. Using a computational analysis, we reveal the framings and controversies emerging from this (...) media discourse. The macro-structuring of discourse on model coexistence revolves around scientific, economic and political framings. Coexistence is a complex of debates based on specific frames associated with specific arenas and actor configurations: growth of organic agriculture, transformations of agrifood systems, sciences of production and impacts, livestock and meat diet controversies, agroecological innovations, CAP reform criticism, discourse of peasant agriculture and State-Profession _co-gestion_. Employing global sentiment analysis and focusing on salient controversies, namely EGAlim law, pesticide regulations, and agribashing, we show the shift from conciliation to a hardening of debates. Finally, we discuss the causes and consequences of this trend. The political will to support the transition of agriculture remains influenced by the _co-gestion_ system, an inherited configuration of decision-makers instrumental in the agricultural modernization. As a consequence, significant agricultural challenges, particularly highlighted in the scientific macro-frame, persist unresolved. This lock-in of the agrifood system is based on defensive strategies that challenge the democratic debate about food and agricultural practices. (shrink)

Unlike in physics, the category of thought experiment is not very common in biology. At least there are no classic examples that are as important and as well-known as the most famous thought experiments in physics, such as Galileo’s, Maxwell’s or Einstein’s. The reasons for this are far from obvious; maybe it has to do with the fact that modern biology for the most part sees itself as a thoroughly empirical discipline that engages either in real natural history or in (...) experimenting on real organisms rather than fictive ones. While theoretical biology does exist and is recognized as part of biology, its role within biology appears to be more marginal than the role of theoretical physics within physics. It could be that this marginality of theory also affects thought experiments as sources of theoretical knowledge. Of course, none of this provides a sufficient reason for thinking that thought experiments are really unimportant in biology. It is quite possible that the common perception of this matter is wrong and that there are important theoretical considerations in biology, past or present, that deserve the title of thought experiment just as much as the standard examples from physics. Some such considerations may even be widely known and considered to be important, but were not recognized as thought experiments. In fact, as we shall see, there are reasons for thinking that what is arguably the single most important biological work ever, Charles Darwin’s On the Origin of Species, contains a number of thought experiments. There are also more recent examples both in evolutionary and non-evolutionary biology, as we will show. Part of the problem in identifying positive examples in the history of biology is the lack of agreement as to what exactly a thought experiment is. Even worse, there may not be more than a family resemblance that unifies this epistemic category. We take it that classical thought experiments show the following characteristics: They serve directly or indirectly in the non-empirical epistemic evaluation of theoretical propositions, explanations or hypotheses. Thought experiments somehow appeal to the imagination. They involve hypothetical scenarios, which may or may not be fictive. In other words, thought experiments suppose that certain states of affairs hold and then try to intuit what would happen in a world where these suppositions are true. We want to examine in the following sections if there are episodes in the history of biology that satisfy these criteria. As we will show, there are a few episodes that might satisfy all three of these criteria, and many more if the imagination criterion is dropped or understood in a lose sense. In any case, this criterion is somewhat vague in the first place, unless a specific account of the imagination is presupposed. There will also be issues as to what exactly “non-empirical” means. In general, for the sake of discussion we propose to understand the term “thought experiment” here in a broad rather than a narrow sense here. We would rather be guilty of having too wide a conception of thought experiment than of missing a whole range of really interesting examples. (shrink)

A hipótese que propomos aqui defende que o dispositivo do "médico da civilização" montado em 1962 pela leitura que Deleuze faz de Nietzsche, longe de poder ser generalizado como tal (como se a sequência da obra deleuziana não fosse senão a sua aplicação diferenciada ou mesmo a sua continuação por outros meios), somente age nessa sequencia por força de um deslocamento da enunciação deleuziana em relação à instância da filosofia clínica que ele define. E que, por essa razão, a figura (...) do filósofo como médico da civilização permite melhor problematizar algumas dificuldades que a tarefa de uma sintomatologia dos modos coletivos de existência encontra. Ao tomar esta tarefa a sério, eu diria, finalmente, que o deslocamento do dispositivo nietzschiano em relação ao encontro com Guattari e ao Anti-Édipo encontra um ponto de resolução, ou pelo menos coerência e equilíbrio, na determinação de uma prática analítica sui generis, a mesma que Guattari designa "esquizo-análise" e, mais especificamente, no conceito de agenciamento que, de Anti-Édipo a Mil Platôs, vai suportar cada vez mais claramente suas coordenadas próprias.

Interroger le futur n'est pas une préoccupation nouvelle pour la philosophie.

Guillaume Collett questions to what extent we can locate Deleuze within the Lacanian School during the late-1960s, prior to Guattari. In so doing, he offers a new, integrated reading of Deleuze's The Logic of Sense by understanding it as a 'psychoanalysis of sense', and gives a new interpretation of Deleuze's conception of philosophy itself. The Psychoanalysis of Sense shows that Deleuze was not merely aware of the debates animating the Lacanian School during the 1960s: he sought to contribute to (...) them. Emphasising his appropriation of the work of post-Lacanian Serge Leclaire, Collett explains how Deleuze constructed a more singular and immanent theory of the linguistic structure of the unconscious - granting the erogenous body a larger structuring role.

Dans cet article, il est question des fondements du récit cinématographique. Contre une thèse endossée par des théoriciens du cinéma français (Metz, Oudart) aussi bien que des philosophes américains (Levinson, Chatman), je défends qu’il n’existe pas de narrateur cinématographique implicite. Pour ce faire, je montre que l’argument a priori, d’après lequel la notion même de récit cinématographique implique qu’il y ait dans tout film, même implicitement, un narrateur, est erroné. En me reposant sur Gaut, j’avance que le postulat d’un narrateur (...) implicite conduit à une conception absurde de l’expérience du spectateur. Je conclus qu’il convient d’abandonner ce platonisme à l’égard du récit cinématographique, pour lui préférer, suivant une remarque de Bordwell, un nominalisme. (shrink)

ObjectivesFrom a self-determination theory perspective, the purpose of this cross sectional study was to better understand how to motivate hospitalized older adults’ behaviors and test an integrative model of the role of causality orientations and a supportive/controlled environment on basic need satisfaction, motivation for health oriented physical activity, positive and negative affective states, depressive symptoms, apathy, and boredom.MethodsOlder adults in French hospital units completed self-report questionnaires and socio-demographic data were also collected.ResultsPartial least squares path modeling results showed that participants’ autonomy (...) orientation positively associated with the perception of a supportive environment was related to need satisfaction, autonomous motivation for health-oriented physical activity, and high scores on positive affective states. Conversely, participants’ impersonal orientation positively associated with the perception of a controlled environment was related to undermining need satisfaction, controlled motivation for health-oriented physical activity, and amotivation, and high scores on both negative affective states, and boredom.ConclusionThe present results indicate that taking into account personality factors in hospital units can be useful and health professionals should take an interest both in the patients’ causality orientations and the supportive nature of the environment in order to understand better how to motivate patients’ behaviors. The present study points to the need to focus on all motivational dynamics which allow patients’ need satisfaction. (shrink)

Ego et communauté. Au contraire de la position défendue par la plupart des interprètes de Husserl qui, au nom de l'intersubjectivité, lui reprochent de suivre une "voie cartésienne" et d'accorder un privilège à l'ego cogito, il s'agit de montrer que cette critique n'est pas fondée : le primat méthodologique de l'ego est au contraire une condition nécessaire pour constituer la communauté intersubjective, et éviter de subordonner l'individualité vivante à une "transcendance" anonyme. L'enjeu est de comprendre la crise des temps modernes (...) comme celle d'un monde aliéné qui s'est fondé sur l'oubli de la vie, mais aussi sur le déni du pouvoir constituant de l'ego et la répression de toute subjectivité."--Page 4 of cover.

Cet article tente de montrer comment Gilles Deleuze et Félix Guattari se sont saisis de la pensée de Karl Marx pour fonder leur théorie anti-idéaliste du désir. Pour cela, il étudie les références principales faites à Marx dans le premier chapitre de l’Anti-Œdipe, chapitre qui pose les bases de la conception deleuzienne du désir. A partir de là, il tente de voir s’il est possible de faire converger le projet politique de Marx et celui de Deleuze et Guattari.

One way social scientists explain phenomena is by building structural models. These models are explanatory insofar as they manage to perform a recursive decomposition on an initial multivariate probability distribution, which can be interpreted as a mechanism. Explanations in social sciences share important aspects that have been highlighted in the mechanisms literature. Notably, spelling out the functioning the mechanism gives it explanatory power. Thus social scientists should choose the variables to include in the model on the basis of their function (...) in the mechanism. This paper examines the notion of ‘function’ within structural modelling. We argue that ‘functions’ ought to be understood as the theoretical underpinnings of the causes, namely as the role that causes play in the functioning of the mechanism. (shrink)

Although Wilhelm Dilthey and Franz Brentano apparently were pursuing roughly the same objective—to offer a description of our mental functions and of their relations to objects—and both called their respective research programs ‘descriptive psychology’, they seem to have used the term to refer to two different methods of psychological research. In this article, I compare analyses of these differences. Against the reading of Orth but also against a possible application of recent relativist accounts of the epistemology of peer disagreement to (...) this case, I argue that their apparent shared objective is not enough to support an understanding of their views as two alternatives within a given historical or scientific context, or as a mutual peer disagreement. I show that the impression of a shared objective can be explained away as stemming from the influence of their teacher Adolf Trendelenburg, and I stress that the case of introspection strongly suggests that an account in terms of peer disagreement is not plausible. Finally, I conclude that the opposition between two traditions, Austrian philosophy and historicism, might be better suited to account for the dispute and its apparent common historical context.

The Grand Challenges literature brings under its umbrella a wide variety of disjointed phenomena but runs the risk of reinventing the wheel as well as overlooking incremental progress and past work. To avert this, scholars need to (dis)connect (dis)similar issues, build on past research on these issues, and create opportunities for generalizability through theoretical examinations.

Corporate codes of ethics, which have spread in the last decades, have shown a limited ability to foster ethical behaviors. For instance, they have been criticized for relying too much on formal compliance, rather than taking into account sufficiently agents and their moral development, or promoting self-reflexive behaviors. We aim here at showing that a code of ethics in fact has meaning and enables ethical progress when it is interpreted and appropriated with practical wisdom. We explore a model that represents (...) an uncommon organizational code of ethics: the monastic Rule of St. Benedict, written in the sixth century and still used today. Our empirical study—conducted in several monasteries living under this rule—shows that organization members interpret this rule, both hermeneutically and ethically, to adapt it to situations. They also appropriate this rule as a way of life and treat it as a dynamic framework that helps them to follow their purpose within their organization. This exceptional code actually offers an alternative model for practicing codes of ethics, in a virtue-ethical manner, beyond mere compliance with the text. The way in which reflexive and active agents practice the code, both individually and collectively, shapes their organizational experience and fosters their moral development. (shrink)

Uncertainty is recognized as a key issue in water resources research, amongst other sciences. Discussions of uncertainty typically focus on tools and techniques applied within an analysis, e.g. uncertainty quantification and model validation. But uncertainty is also addressed outside the analysis, in writing scientific publications. The language that authors use conveys their perspective of the role of uncertainty when interpreting a claim —what we call here “framing” the uncertainty. This article promotes awareness of uncertainty framing in four ways. 1) It (...) proposes a typology of eighteen uncertainty frames, addressing five questions about uncertainty. 2) It describes the context in which uncertainty framing occurs. This is an interdisciplinary topic, involving philosophy of science, science studies, linguistics, rhetoric, and argumentation. 3) We analyze the use of uncertainty frames in a sample of 177 abstracts from the Water Resources Research journal in 2015. This helped develop and tentatively verify the typology, and provides a snapshot of current practice. 4) Provocative recommendations promote adjustments for a more influential, dynamic science. Current practice in uncertainty framing might be described as carefully-considered incremental science. In addition to uncertainty quantification and degree of belief (present in ~5% of abstracts), uncertainty is addressed by a combination of limiting scope, deferring to further work (~25%) and indicating evidence is sufficient (~40%) – or uncertainty is completely ignored (~8%). There is a need for public debate within our discipline to decide in what context different uncertainty frames are appropriate. Uncertainty framing cannot remain a hidden practice evaluated only by lone reviewers. (shrink)

The development of phenomenology in nineteenth‐century German philosophy is that of a particular stream within the larger historical‐philosophical complex of Austro‐German philosophy. As the “grandfather of phenomenology” resp. the “disgusted grandfather of phenomenology,” but also as the key figure on the “Anglo‐Austrian Analytic Axis”, Brentano is at the source of the two main philosophical traditions in twentieth‐century philosophy. This chapter focuses mainly on his place in nineteenth‐century European philosophy and on the central themes and concepts in his philosophy that were (...) determinant in the development of the philosophy of his most gifted student: Edmund Husserl. Despite the variety of stances which Brentano expressed on ontology, metaphysics, and psychology over the course of his career, the five general principles remain central to his whole philosophy throughout: they have an important place in what could be called Brentano's philosophical worldview or system. By extension, they also are essential to his conception of phenomenology. (shrink)
