This pioneering book demonstrates the crucial importance of Wittgenstein's philosophy of mathematics to his philosophy as a whole. Marion traces the development of Wittgenstein's thinking in the context of the mathematical and philosophical work of the times, to make coherent sense of ideas that have too often been misunderstood because they have been presented in a disjointed and incomplete way. In particular, he illuminates the work of the neglected 'transitional period' between the Tractatus and the Investigations.

The starting point of this conversation with philosopher Mathieu Triclot is the issue of the causal contribution of video game playing in school shootings. Triclot explains the limitations of current psychological approaches regarding video game violence. He further develops on the peculiar features of the video game medium and how they relate to the problem of violence. Triclot eventually shows that, although players may relate to virtual violence in very different ways, violence in video games is not merely a (...) subjective phenomenon. He highlights that some “regimes of experience,” which got stable in the video game culture, cultivate a toxic relation to violence. (shrink)

If the Bounded Proper Forcing Axiom BPFA holds, then Mouse Reflection holds at N₂ with respect to all mouse operators up to the level of Woodin cardinals in the next ZFC-model. This yields that if Woodin's ℙ max axiom (*) holds, then BPFA implies that V is closed under the "Woodin-in-the-next-ZFC-model" operator. We also discuss stronger Mouse Reflection principles which we show to follow from strengthenings of BPFA, and we discuss the theory BPFA plus "NS ω1 is precipitous" and strengthenings (...) thereof. Along the way, we answer a question of Baumgartner and Taylor. [2, Question 6.11]. (shrink)

A Polish space is not always homeomorphic to a computably presented Polish space. In this article, we examine degrees of non-computability of presenting homeomorphic copies of compact Polish spaces. We show that there exists a $\mathbf {0}'$ -computable low $_3$ compact Polish space which is not homeomorphic to a computable one, and that, for any natural number $n\geq 2$, there exists a Polish space $X_n$ such that exactly the high $_{n}$ -degrees are required to present the homeomorphism type of $X_n$. (...) Along the way we investigate the computable aspects of Čech homology groups. We also show that no compact Polish space has a least presentation with respect to Turing reducibility. (shrink)

Les colonies de Terre Sainte, en dépit de trois croisades successives, ont abordé le dernier quart du 13e siècle dans un état de faiblesse inquiétant. Le pape Grégoire X a essayé durant cinq ans de redresser la situation par tous les moyens. L'A. retrace tout d'abord la destinée exceptionnelle de ce pape, de son vrai nom Tebaldo Visconti, né à Plaisance en 1210 et mort à Arezzo en 1276. Il étudie ensuite l'action de Grégoire X dans son redressement spirituel de (...) l'Orient latin. Son désir profond de venir en aide à la Terre Sainte s'exprima aussi dans des mesures financières. Les limites de l'action du Saint-Siège sont étudiées ainsi que le soutien logistique des colonies franques de Syrie apporté au pape. L'évolution de la conjoncture internationale compromit sérieusement à partir de 1273 les retombées ses efforts. (shrink)

After sketching an argument for radical anti-realism that does not appeal to human limitations but polynomial-time computability in its definition of feasibility, I revisit an argument by Wittgenstein on the surveyability of proofs, and then examine the consequences of its application to the notion of canonical proof in contemporary proof-theoretical-semantics.

High-fidelity cultural transmission, rather than brute intelligence, is the secret of our species’ success, or so many cultural evolutionists claim. It has been selected because it ensures the spread, stability and longevity of beneficial cultural traditions, and it supports cumulative cultural change. To play these roles, however, fidelity must be a causally-efficient property of cultural transmission. This is where the grain problem comes in and challenges the explanatory potency of fidelity. Assessing the degree of fidelity of any episode or mechanism (...) of cultural transmission always depends upon an investigator’s choice of grain of description at which cultural traditions are being studied. The fidelity of cultural transmission then appears to be relative to the granularity at which one approaches cultural variation, and since there is a multiplicity of grains of description by which the same tradition can be studied, there results a multiplicity of measures of fidelity for a same event or mechanism of cultural transmission. If this is correct, because fidelity is always relative to the grain of description dictated by the local and specific research interests of the investigator, then there seems to be no fact of the matter as to whether cultural transmission is faithful or not, independently from a researcher’s framework of analysis. The aims of this paper are to offer a conceptual clarification of the grain problem in cultural evolution, to assess its causes, to unpack its epistemological implications, and to examine its reach and consequences for a science of cultural evolution.

The study of ergodic theorems from the viewpoint of computable analysis is a rich field of investigation. Interactions between algorithmic randomness, computability theory and ergodic theory have recently been examined by several authors. It has been observed that ergodic measures have better computability properties than non-ergodic ones. In a previous paper we studied the extent to which non-ergodic measures inherit the computability properties of ergodic ones, and introduced the notion of an effectively decomposable measure. We asked the following question: if (...) the ergodic decomposition of a stationary measure is finite, is this decomposition effective? In this paper we answer the question in the negative. (shrink)

Many people hold this truth to be self-evident that universities should enroll more female students in science and engineering; the main question then being how. Typical arguments include possible benefits to women, possible benefits to the economy, and the unfairness of the current female under-representation. However, when clearly stated and scrutinized these arguments in fact lead to the conclusion that there should be more women in scientific disciplines in higher education in the sense that we should expect more women (which (...) various kinds of discrimination may prevent), not that we should actively enroll more women. Outreach programs towards high school students may therefore be logically incompatible with the arguments supposed to justify them. They should purport to allow women to graduate in a field congruent with her abilities and desires, rather than try to draw as many of them to scientific disciplines as possible: one cannot try to ‘recruit’ as many female students as possible while claiming to help them choose more freely.

Research has shown that context influences how sincere a smile appears to observers. That said, most studies on this topic have focused exclusively on situational cues (e.g. smiling while at a party versus smiling during a job interview) and few have examined other elements of context. One important element concerns any knowledge an observer might have about the smiler as an individual (e.g. their habitual behaviours, traits or attitudes). In this manuscript, we present three experiments that explored the influence of (...) such knowledge on ratings of smile sincerity. In Experiments 1 and 2, participants rated the sincerity of Duchenne and non-Duchenne smiles after having been exposed to cues about the smiler’s tendency to reciprocate (this person always, never or occasionally returns favours). In Experiment 3 they performed the same task but with cues about the smiler’s love of learning (this person always, never or occasionally enjoys learning new tasks). The results show that cues about the smiler’s reciprocity tendency influenced participants’ ratings of smile sincerity and did so in a stronger manner than cues about the smiler’s love of learning. Overall, these results both strengthen and broaden the literature on the role of context on judgements of smile sincerity. (shrink)

À partir d’un paradoxe que soulève Montaigne et de ses prolongements au XVII e siècle, cet article explore ce singulier revers de la raison qu’est la sottise. Montaigne s’étonne qu’une même tête, celle du pédant, qui cristallise par excellence la sottise, puisse à la fois être savante et n’en être pas moins sotte. L’analyse de ce paradoxe conduit Montaigne à pointer la mauvaise façon qu’ont les pédants de se rapporter à la science, et découvre que c’est la manière de l’animer (...) qui importe et qui la rend véritable. Nous éclaircissons ensuite la notion de manière, souvent convoquée au Grand Siècle pour suggérer ce qui échappe à une raison trop peu fine. Enfin, nous indiquons qu’un nouveau modèle, celui de la machine, émerge dans la postérité cartésienne pour dire la sottise. Chez La Bruyère, entre autres, le sot est ainsi celui qui parle et agit mécaniquement. (shrink)

According to Clifford Geertz, the purpose of anthropology is not to explain culture but to explicate it. That should cause us to rethink our relationship with machine learning. It is, we contend, perfectly possible that machine learning algorithms, which are unable to explain, and could even be unexplainable themselves, can still be of critical use in a process of explication. Thus, we report on an experiment with anthropological AI. From a dataset of 175K Facebook comments, we trained a neural network (...) to predict the emoji reaction associated with a comment and asked a group of human players to compete against the machine. We show that a) the machine can reach the same accuracy as the players, b) it fails in roughly the same ways as the players, and c) easily predictable emoji reactions tend to reflect unambiguous situations where interpretation is easy. We therefore repurpose the failures of the neural network to point us to deeper and more ambiguous situations where interpretation is hard and explication becomes both necessary and interesting. We use this experiment as a point of departure for discussing how experiences from anthropology, and in particular the tension between formalist ethnoscience and interpretive thick description, might contribute to debates about explainable AI.

L’intelligence artificielle est partout, l’air de rien, pour mieux nous contrôler et nous orienter en douceur. Faut-il se rebeller contre cet état de fait, qui s’impose à nos modes de vie sans la moindre délibération démocratique? Est-il encore possible ou même souhaitable de jeter ces IA invisibles, voire indiscernables, à la poubelle du numérique? Ne faudrait-il pas, avant de clamer l’urgence du « danger » qui vient, oser les connaître?

In fungi, cell fusion between genetically unlike individuals triggers a cell death reaction known as the incompatibility reaction. In Podospora anserina, the genes controlling this process belong to a gene family encoding STAND proteins with an N‐terminal cell death effector domain, a central NACHT domain and a C‐terminal WD‐repeat domain. These incompatibility genes are extremely polymorphic, subject to positive Darwinian selection and display a remarkable genetic plasticity allowing for constant diversification of the WD‐repeat domain responsible for recognition of non‐self. Remarkably, (...) the architecture of these proteins is related to pathogen‐recognition receptors ensuring innate immunity in plants and animals. Here, we hypothesize that these P. anserina incompatibility genes could be components of a yet‐unidentified innate immune system of fungi. As already proposed in the case of plant hybrid necrosis or graft rejection in mammals, incompatibility could be a by‐product of pathogen‐driven divergence in host defense genes. (shrink)

Schools located in underpriviledged areas have to deal with different factors, like the dropout rate among students and teachers; the culture of action, the culture of oral and a «carpe diem» culture; the low literacy rates; the type of children's knowledges — sometimes different from those promoted at school — and the learning difficulties of pupils... In light of these factors, few states have decided to adopt measures to support pupils and teachers in these communities. In this sense, several studies (...) examine the potential role of philosophy for children (P4C), but none examines, in this kind of environment, the integration of P4C in the context of a teaching field experience program. Insofar several novice teachers start their career in these environments, it could be helpful to enrich our comprenhension on this subject. This paper presents results from an exploratory study on this issue, which led to raise questions about the bachelor of education program, at least in our university. (shrink)

Cet article analyse la plainte en grossesse de Catherine Lespinasse contre Jean Gaudens dit Capdeville déposée aux greffes de la justice des capitouls de Toulouse le 16 juin 1742 dans laquelle la plaignante dénonce un viol commis par l’homme qu’elle fréquentait en vue d’un prochain mariage. Cette contribution expose plusieurs des obstacles légaux empêchant une femme victime de viol de porter formellement plainte pour ce crime au xviiie siècle. L’étude de ce cas démontre cependant que, comme Catherine Lespinasse, plusieurs femmes (...) usèrent consciemment de leurs capacités d’agir en justice pour dénoncer indirectement leur agresseur en utilisant le mécanisme de la plainte en grossesse qui se voulait, à la base, une procédure judiciaire paternaliste et coercitive les forçant à déclarer en justice leur grossesse illégitime.

Nous tenterons ici d’élucider le sens de la référence quelque peu surprenante de H. G. Gadamer à la doctrine médiévale des transcendantaux à la fin de Vérité et méthode. Le concept d’appartenance signifie pour Gadamer l’insertion de la connaissance dans l’être. Nous soutenons que la thèse fondamentale de Gadamer, l’être susceptible d’être compris est langage, ne signifie pas que l’être soit «soumis» au langage, mais suggère plutôt une certaine intelligibilité de l’être auquel l’homme participe par le biais de la connaissance. (...) Ceci nous reconduit à deux doctrines clés issues de la philosophie médiévale en ce qui concerne le problème de la vérité, soit les transcendantaux et la définition classique de la vérité comme adaequatio rei et intellectus.

Do usual commercials elicit the full spectrum of emotions? For this perspective paper, we posit that they do not. Concepts and measures related to the adaptive functions and well-being areas of emotion research cannot simply be transferred for use in advertising research. When a commercial elicits emotions, the emotions staged in the commercial must not be directly associated with the emotions felt by consumers when exposed to those commercials. This is why “aesthetic” emotions seem more appropriate than “utilitarian” emotions in (...) advertising research, with the former generally felt more significantly than they are acted upon. Aesthetic emotions elicit limited physiological change, and they rely on the intrinsic pleasantness appraisal of commercials. Accordingly, pleasure and displeasure—as observed through expressive and subjective components of aesthetic emotion—often form the first and only step of commercial appraisal, and they are directed toward attitude formation rather than overt behaviors. Our preliminary psychophysiological study shows this by investigating the contributions of psychophysiological and self-reported measures of aesthetic emotions induced by commercials to explain attitudes toward advertisements. The results show that only two components of aesthetic emotion positively influenced attitudes toward the advertisements: expressive (measured by facial electromyography) and subjective (measured by the self-assessment manikin scale). Also, the subjective component of aesthetic emotion partially mediates the effects of the expressive components on attitudes toward the ads. Our exploratory study illustrates the relevance of focusing on aesthetic emotions in advertising research. It also shed new light on the contributions of the physiological, expressive, and subjective feelings components of aesthetic emotions in advertising effectiveness. (shrink)

In this short paper we analyse some paradoxical aspects of France’s Foucauldian heritage: while several French scholars claim the COVID-19 pandemic is a perfect example of what Foucault called biopolitics, popular reaction instead suggests a biopolitical failure on the part of the government; One of these failures concerns the government’s inability to produce reliable biostatistical data, especially regarding health inequalities in relation to COVID-19. We interrogate whether Foucaldianism contributed, in the past as well today, towards a certain myopia in France (...) regarding biostatistics and its relation to social inequalities in health. One might ask whether this very data could provide an appropriate response to the Foucauldian question: What kind of governance of life is the pandemic revealing to us? (shrink)

We propose a logic of abduction that (i) provides an appropriate formalization of the explanatory conditional, and that (ii) captures the defeasible nature of abductive inference. For (i), we argue that explanatory conditionals are non-classical, and rely on Brian Chellas’s work on conditional logics for providing an alternative formalization of the explanatory conditional. For (ii), we make use of the adaptive logics framework for modeling defeasible reasoning. We show how our proposal allows for a more natural reading of explanatory relations, (...) and how it overcomes problems faced by other systems in the literature. (shrink)

We know from Li's theorem (1993) that the stability set of order d may be empty for some preference profiles. However, one may wonder whether such situations are just rare oddities or not. In this paper, we partially answer this question by considering the restrictive case where the number of alternatives is the smallest compatible with an empty stability set. More precisely, we provide an upper bound on the probability for having an empty stability set of order d for the (...) majority game under the Impartial Weak Ordering Culture assumption. This upper bound is already extremely low for small population and tends to zero as the number of individuals goes to infinity. (shrink)

In this paper, I examine the transmission of some ideas of the pragmatist tradition to Wittgenstein, in his ‘middle period,’ through the intermediary of F. P. Ramsey, with whom he had numerous fruitful discussions at Cambridge in 1929. I argue more specifically that one must first come to terms with Ramsey’s own views in 1929, and explain how they differ from views expressed in earlier papers from 1925-27, so a large part of this paper is devoted to this task. One (...) is then in a better position to understand the impact of Ramsey’s astute critique of Wittgenstein’s Tractatus Logico-Philosophicus in conjunction with his pragmatism, and explain how it may have set into motion the ‘later’ Wittgenstein. I then argue that Ramsey introduced his notion of ‘variable hypothetical’ as a rule, not a proposition, on pragmatist grounds and that Wittgenstein picked this up in 1929, along with a more ‘dynamic’ view of meaning than the ‘static’ view of the Tractatus, and that this explains in part Wittgenstein’s turn to his ‘later philosophy.’.

Many engineering ethics classes and textbooks introduce theories such as utilitarianism and Kantianism (and most others draw from these theories without mentioning them explicitly). Yet using ethical theories to teach engineering ethics is not devoid of difficulty. First, their status is unclear (should one pick a single theory or use them all? does it make a difference?) Also, textbooks generally assume or fallaciously ‘prove’ that egoism (or even simply accounting for one’s interests) is wrong. Further, the drawbacks of ethical theories (...) are underestimated and the theories are also otherwise misrepresented to make them more suitable for engineering ethics as the authors construe it, viz. the ‘moral reasoning’ process. Stating in what various theories disagree would allow the students to frame the problem more productively in terms of motive–consequence or society–individual dichotomies rather than in terms of Kant–utilitarian.

La réception de John Rawls et des théories de la justice Souvent présenté comme un des plus grands théoriciens politiques du XXe siècle, John Rawls est aujourd'hui un philosophe consacré en France, communément perçu comme le porte-parole d'un " libéralisme égalitaire ", alliant défense de la démocratie, du marché et de la justice sociale. La réception de John Rawls et des théories de la justice Souvent présenté comme un des plus grands théoriciens politiques du XXe siècle, John Rawls est aujourd'hui (...) un philosophe consacré en France, communément perçu comme le porte-parole d'un " libéralisme égalitaire ", alliant défense de la démocratie, du marché et de la justice sociale. Rien ne laissait pourtant présager l'entrée dans le canon académique et dans le débat politique d'une oeuvre longtemps ignorée des philosophes et intellectuels français. Cette consécration tardive constitue le terme d'une histoire qui court du début des années 1970 aux années 2000, durant laquelle les lectures les plus diverses de Rawls se sont affrontées. Porté par une écriture dynamique et accessible, l'ouvrage de Mathieu Hauchecorne rend compte de la réception française de ce qu'on a communément appelé les " théories de la justice ". Il retrace les circulations de Rawls mais aussi d'auteurs comme Robert Nozick, Michael Walzer ou Amartya Sen entre les Etats-Unis et la France ; entre économie, philosophie, sociologie, droit et science politique ; et entre champ intellectuel et champ politique. Une histoire inséparable de reconfigurations plus globales, comme la domination accrue de l'anglais sur les échanges intellectuels transnationaux, l'affirmation d'une gauche non-marxiste en France, et les débats relatifs aux politiques de redistribution. Une contribution majeure à une sociologie de la pensée politique contemporaine. (shrink)
