Résumé Le débat sur le « naturalisme historique », qui a opposé sous le Second Empire Albert de Broglie à dom Prosper Guéranger, est une étape essentielle dans le processus, jalonné de « cas » mieux connus comme ceux de Renan, Duchesne ou Loisy, qui a vu la majorité des historiens catholiques se rallier progressivement à un type d’écriture de l’histoire qui relève peu ou prou, avec des nuances, de l’agnosticisme méthodologique. Ce débat très oublié, qui intervenait dans une (...) époque marquée par d’intenses discussions religieuses, a soulevé des questions fondamentales sur l’action de Dieu dans l’histoire et la place qu’il convenait de lui reconnaître dans l’histoire des historiens, qui ne sont pas sans lien avec les problèmes qui seront discutés âprement un demi-siècle plus tard dans le cadre de la crise moderniste.

This book analyses the evolution of the French model of capitalism in relation to the instability of socio-political compromises. In the 2010s, France was in a situation of systemic crisis, namely, the impossibility for political leadership to find a strategy of institutional change, or more generally a model of capitalism, that could gather sufficient social and political support. This book analyses the various attempts at reforming the French model since the 1980s, when the left tried briefly to orient the French (...) political economy in a social-democratic/socialist direction before changing course and opting for a more orthodox macroeconomic and structural policy direction. The attempts of governments of the right to implement a radically neo-liberal structural policy also failed in the face of a significant social opposition. The enduring French systemic crisis is the expression of contradictions between the economic policies implemented by the successive left and right governments, and the existence of a dominant, social bloc, that is, a coalition of social groups that would politically support the dominant political strategy. Since 1978, both the right and the left have failed to find a solution to the contradictions between the policies they implemented and the expectations of their respective social bases, which are themselves inhabited by tensions and contradictions that evolve with the structural reforms that gradually transformed French capitalism.

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.

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)

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.

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.

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".

While Corporate Social Responsibility (CSR) is often seen to involve voluntary and deliberative approaches such as certification, governments have recently stepped into the picture through national legislation. France’s Law on Duty of Vigilance adopted in 2017 is a landmark case of such legislation. Years of voluntary CSR certification schemes led by Civil Society were replaced by a new philosophy of fighting for mandatory CSR controlled by a judge. We depict the change of mindset and the related change of roles inside (...) the coalition of Civil Society actors represents a Machiavellian Moment. The combination of collective civil society actors’ roles (namely nongovernmental organizations and labor unions) as Machiavellian _Virtue_ with disruptive events as Machiavellian _Fortuna_ made the law’s adoption possible. Based on this case study, we provide an analysis of civil society roles in the development of CSR-related legislation. (shrink)

Critical thinking is often taught with some emphasis on categories and operations of cognitive biases. The underlying thought is that knowledge of biases equips students to reduce them. The empirical evidence, however, doesn’t provide much support for this thought. We have previously argued that the emphasis on debiasing in critical thinking education is worth preserving, but in light of a more explicit and broader conception of debiasing. We now argue that this broader conception of debiasing strategies obliges critical thinking instructors (...) and curriculum designers to reflect on the teaching approaches that might facilitate the use of those strategies. We propose some teaching techniques to expand the scope of debiasing in the classroom—some untested, some only rarely and recently characterized as critical thinking strategies, rather than as pragmatic considerations in, e.g., design, engineering, marketing. These methods and others like them, we suggest, broaden the prospects for teaching a range of effective critical thinking techniques for debiasing. (shrink)

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)

Résumé David Chalmers maintient que la réalité virtuelle est une véritable réalité. Une version de ce « réalisme virtuel » affirme que les entités virtuelles dépendent ontologiquement d'entités numériques réelles. Nous explorons ici cette suggestion, en proposant un nouveau modèle pour décrire la dépendance du virtuel à l’égard du numérique. En nous appuyant sur la théorie de la constitution de Lynne Rudder Baker, nous défendons que les objets virtuels sont constitués par des objets numériques, lorsque ceux-ci se trouvent dans certaines (...) circonstances favorables. Nous explorons les motivations et les implications de cette approche, que nous considérons comme une forme prometteuse de réalisme virtuel. (shrink)

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)

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)

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.

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.

In this paper, we use an experimental design to compare the performance of elicitation rules for subjective beliefs. Contrary to previous works in which elicited beliefs are compared to an objective benchmark, we consider a purely subjective belief framework. The performance of different elicitation rules is assessed according to the accuracy of stated beliefs in predicting success. We measure this accuracy using two main factors: calibration and discrimination. For each of them, we propose two statistical indexes and we compare the (...) rules’ performances for each measurement. The matching probability method provides more accurate beliefs in terms of discrimination, while the quadratic scoring rule reduces overconfidence and the free rule, a simple rule with no incentives, which succeeds in eliciting accurate beliefs. Nevertheless, the matching probability appears to be the best mechanism for eliciting beliefs due to its performances in terms of calibration and discrimination, but also its ability to elicit consistent beliefs across measures and across tasks, as well as its empirical and theoretical properties.

In this paper, I discuss the distribution and the interpretation of the temporal suffix -kue in Mbyá, a Guaraní language that is closely related to Paraguayan Guaraní. This suffix is attested both inside noun phrases and inside clauses. Interestingly, its nominal uses give rise to inferences that are unattested in its clausal uses. These inferences were first identified in Paraguayan Guaraní by Tonhauser, who called them the existence property and the change of state property. Tonhauser further argued that these properties (...) are built into the lexical entry of the nominal temporal marker -kue. By contrast, I argue that -kue denotes a relative past tense both in its nominal and clausal uses, and that the existence and change of state properties are pragmatic inferences that arise from the interaction of the literal meaning of -kue with general constraints on the interpretation of noun phrases, notably constraints on the topicality of the time of evaluation of noun phrases. This allows me to maintain a uniform analysis of -kue across its nominal uses and its clausal uses. The analysis of -kue in Mbyá is relevant to a number of current debates on the expression of tense crosslinguistically. Firstly, the existence of relative tenses has sometimes been called into question. Klein notably argues that relative tenses are actually combinations of tense with the perfect aspect. Others have argued that there exist true relative tenses in certain languages. I argue that facts of Mbyá support the latter view. Secondly, Klein famously defined tenses as relations between topic times and the time of utterance. I argue, on the other hand, that relative tenses only denote relations between times, and that the topicality or non-topicality of their temporal arguments depends on their context of use, including their syntactic environment. Thirdly, this paper contributes to debates on the nature and reality of nominal tenses The Oxford handbook of tense and aspect, 2012), by arguing that tense in Mbyá is a genuinely nominal category, in the sense that temporal functional projections are part of the extended projection of the noun phrase.

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)

Dans cet article, je propose de relire l’épistémologie de du Châtelet à l’aune de la question de l’autorité. Je montre que les outils méthodologiques convoqués dans les premiers chapitres des Institutions de physique (1740), à savoir le principe de non-contradiction, le principe de raison suffisante, ainsi que la théorie des hypothèses du chapitre 4, peuvent être compris comme des moyens de contrôler l’usage des systèmes des grands auteurs que sont Descartes, Leibniz et Newton. Ils permettent en effet d’éviter les dangers (...) du dogmatisme que représentent l’esprit de parti et l’idolâtrie. Ce faisant, je défends que l’une des originalités de l’épistémologie de du Châtelet est d’intégrer à sa théorie de la physique une réflexion sur la meilleure manière de gérer les autorités scientifiques. Cette perspective a l’avantage de court-circuiter la question traditionnelle des influences ou des filiations de du Châtelet, pour lui préférer celle de la façon dont elle use de la tradition.

Cet article vise à comprendre la persistance et la radicalisation de la critique écologique dans l’espace public malgré les tentatives de récupération des questions environnementales par le capitalisme via l’introduction dans les discours managériaux des « concepts verts » (développement durable, RSE, etc.). Nous développons les raisons pour lesquelles la critique écologique semble résister à sa récupération et mobilisons le concept marxien de « fétichisme de la marchandise » pour saisir la critique écologique comme remise en cause des fondements de (...) notre organisation économique. Cette analyse permet de comprendre l’échec des concepts verts et d’éclairer l’évolution des relations entre le capitalisme et sa critique. Classification JEL : A13, B51, P10, Q50, Z1. (shrink)

This conference was devoted to the 80 years of the Copenhagen Interpretation, and to the question of the relevance of the Copenhagen interpretation for the present understanding of quantum mechanics. It is in this framework that fundamental questions raised by quantum mechanics, especially in information theory, were discussed throughout the conference. As has become customary in our series of conference in Växjö, we were glad to welcome a fruitful assembly of theoretical physicists, experimentalists, mathematicians and even philosophers interested in the (...) foundations of probability and physics. The nature of quantum fluctuations---in the form of Stochastic Electrodynamics or in other approaches to stochastic quantum mechanics---was also a central topic discussed during the conference, especially during debates. We should also mention talks on the completeness or incompleteness of quantum mechanics; on macroscopic quantum systems; on Bell's inequality, entanglement and experiments on quantum nonlocality (and locality); on Bohmian mechanics; on the connection between quantum mechanics and general relativity; on quantum probability; on quantum computing, quantum teleportation and quantum cryptography technologies; and more generally on the mathematical formalism of quantum mechanics and on the philosophical problems raised by its interpretations.

This Växjö conference was devoted to the reconsideration of quantum foundations. Due to increasing research in quantum information theory, especially on quantum computing and cryptography, many questions regarding the foundations of quantum mechanics, which have long been considered to be exclusively of philosophical interest, nowadays play an important role in theoretical and experimental quantum physics.

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.

In this paper, we try to define some aspects of a political ethics in Merleau-Ponty's phylosophy. It is possible to describe a recurring and structural problem in his political work: the question of «humanism». This problem implies that the goal of any policy consists in the «institution» of a symbolic link between human beings. We argue that the problem of humanism structures the political thought of the philosopher and explains Merleau-Ponty's relation toMarxism and to history. The courage of the institution, (...) which can be an answer to the problem of humanism, embodies the fondamental political virtue. A virtue that Merleau-Ponty calls «virtue without any resignation».

From Experience to the “Event”The Stakes of the Thought of an “Originary Symbolism”This article proposes to understand the progressive conceptualization of experience as “originary symbolism.” After having examined the notions of form but also – and above all – those of categorical attitude and expression, we show that Merleau-Ponty turns toward a concept of experience that is from the start expressive. Here, the symbolic function, in Cassirer’s sense, is slowly replaced by a “symbolism” in which the diacritical, institution, and the (...) unconscious play a fundamental role. Making use of Merleau-Ponty’s unpublished notes, particularly those in the Sensible World and the World of Expression, allows us to observe the convergence of diacritical thought, institution, and the unconscious toward one unified conception of originary symbolism. Hence, we propose an approach that departs from the traditional categories of consciousness and of evidence, and founds a theory of experience as “event”.Dall’esperienza all’ «evento»La posta in gioco del «simbolismo originario»L’articolo si propone di comprendere la progressiva concettualizzazione merleaupontyana dell’esistenza come «simbolismo originario». Dopo aver esaminato le nozioni di forma, ma anche e soprattutto di atteggiamento categoriale e di espressione, mostreremo che Maurice Merleau-Ponty si indirizza a una concezione dell’esperienza che ne fa qualcosa di immediatamente espressivo; concezione in cui la funzione simbolica, nel senso di Cassirer, viene poco a poco sostituita da un «simbolismo» in cui il diacritico, l’istituzione e l’inconscio giocano un ruolo fondamentale. Il ricorso alle Note inedite di Merleau-Ponty, e in particolare a Le monde sensible et le monde de l’expression, consente appunto di osservare la convergenza dei tre concetti di diacritico, di istituzione e di inconscio, in direzione di una medesima concezione del simbolismo originario. Proponiamo quindi un approccio che si discosta dalle tradizionali categorie della coscienza e dell’evidenza, per fondare una teoria dell’esperienza come «evento». (shrink)
