Ignorant speech, which spreads falsehoods about people and policies, is pervasive in public discourse. A popular response to this problem recommends countering ignorant speech with more speech, rather than legal regulations. However, Mary Kate McGowan has influentially argued that this ‘counterspeech’ response is flawed, as it overlooks the asymmetric pliability of conversational norms: the phenomenon whereby some conversational norms are easier to enact than subsequently to reverse. After demonstrating that this conversational ‘stickiness’ is an even broader concern for counterspeech than (...) McGowan suggests—it applies not just to oppressive or hateful speech, but also to ordinary policy-related misinformation—I argue that a more sophisticated account of counterspeech can nevertheless overcome it. First, the stickiness objection overlooks the distinction between ‘negative’ and ‘positive’ counterspeech. Instead of directly negating a distorted proposition, positive counterspeech affirms a correct proposition that is inconsistent with the falsehoods at hand. This, I contend, allows it to counter ignorant speech without triggering the properties that render it sticky. Second, the stickiness objection presupposes an unrefined conception of counterspeech’s temporality. Counterspeech should be understood as a diachronic process, which not only follows, but also pre-empts, ignorant utterances. Drawing on speech-act theories of silencing, I argue that pre-emptive counterspeech can condition the conversational context so as to prevent subsequent ignorant utterances from enacting sticky conversational norms. Thus, this theoretically-refined conception of counterspeech helps appreciate how verbal responses might overcome the stickiness of conversational norms; and, in doing so, it reveals that this stickiness need not provide reasons to prefer legal remedies to counterspeech.

The use of artificial intelligence (AI) to aid legal decision making has become prominent. This paper investigates the use of AI in a critical issue in employment law, the determination of a worker’s status—employee vs. independent contractor—in two common law countries (the U.S. and Canada). This legal question has been a contentious labor issue insofar as independent contractors are not eligible for the same benefits as employees. It has become an important societal issue due to the ubiquity of the gig (...) economy and the recent disruptions in employment arrangements. To address this problem, we collected, annotated, and structured the data for all Canadian and Californian court cases related to this legal question between 2002 and 2021, resulting in 538 Canadian cases and 217 U.S. cases. In contrast to legal literature focusing on complex and correlated characteristics of the employment relationship, our statistical analyses of the data show very strong correlations between the worker’s status and a small subset of quantifiable characteristics of the employment relationship. In fact, despite the variety of situations in the case law, we show that simple, off-the-shelf AI models classify the cases with an out-of-sample accuracy of more than 90%. Interestingly, the analysis of misclassified cases reveals consistent misclassification patterns by most algorithms. Legal analyses of these cases led us to identify how equity is ensured by judges in ambiguous situations. Finally, our findings have practical implications for access to legal advice and justice. We deployed our AI model via the open-access platform, https://MyOpenCourt.org/, to help users answer employment legal questions. This platform has already assisted many Canadian users, and we hope it will help democratize access to legal advice to large crowds. (shrink)

Maxime Vachon | : L’objectif de cet article est de montrer l’unité du chapitre 14 du Peri Hermeneias, chapitre dans lequel Aristote retourne au fondement de l’échange dialectique, à savoir la doxa. Je montre ainsi que ce chapitre expose progressivement les trois conditions sémantiques que des points de vue doivent respecter pour être contraires : le sujet doit être le même, l’objet doit aussi être le même, mais le mode de prédication doit être contradictoire. | : The aim of this (...) paper is to show the unity of chapter 14 of the Peri Hermeneias, in which chapter Aristotle goes back to the basis of dialectical exchange, that is doxa. Thus I show that this chapter presents in successive order the three semantical conditions that points of view must respect in order to be contrary : the subject has to be the same, the object has also to be the same, but the mode of predication must be contradictory.

When is choice affected by subliminal messages? This question has fascinated scientists and lay people alike, but it is only recently that reliable empirical data began to emerge. In the current paper we bridge the literature on implicit motivation and that on subliminal persuasion. We suggest that motivation in general, and implicit motivation more specifically, plays an important role in subliminal persuasion: It sensitizes us to subliminal cues. To examine this hypothesis we developed a new paradigm that allows powerful tests (...) of subliminal influences as well as stringent assessments of subliminality. The results of two experiments suggest that implicit motivation can enhance the effects of subliminal priming on choice. (shrink)

Cognitive test batteries are widely used in diverse research fields, such as cognitive training, cognitive disorder assessment, or brain mechanism understanding. Although they need flexibility according to their usage objectives, most test batteries are not available as open-source software and are not be tuned by researchers in detail. The present study introduces an open-source cognitive test battery to assess attention and memory, using a javascript library, p5.js. Because of the ubiquitous nature of dynamic attention in our daily lives, it is (...) crucial to have tools for its assessment or training. For that purpose, our test battery includes seven cognitive tasks, common in cognitive science literature. By using the test battery, we conducted an online experiment to collect the benchmark data. Results conducted on 2 separate days showed the high cross-day reliability. Specifically, the task performance did not largely change with the different days. Besides, our test battery captures diverse individual differences and can evaluate them based on the cognitive factors extracted from latent factor analysis. Since we share our source code as open-source software, users can expand and manipulate experimental conditions flexibly. Our test battery is also flexible in terms of the experimental environment, i.e., it is possible to experiment either online or in a laboratory environment. (shrink)

The seed system is a major component of traditional management of crop genetic diversity in developing countries. Seed flows are an important part of this system. They have been poorly studied for minor Andean crops, especially those that are propagated vegetatively. We examine the seed exchanges of Oxalis tuberosa Mol., a vegetatively propagated crop capable of sexual reproduction. We studied the seed exchanges of four rural communities in Candelaria district at the international and local levels, emphasizing the spread of new (...) sexually-produced genotypes through these exchanges. Interviews with 44 farmers generated socioeconomic, agronomic, crop diversity and seed exchange information, and data on the potential incorporation of new sexually-produced genotypes in the crop germplasm. We interviewed merchants to evaluate the input and output of genetic diversity in the communities studied. Results showed a positive effect of the farmers’ wealth on the diversity cultivated and on seed exchanges. Most seed exchanges occurred at market, creating a distinction between cash and self-consumption landraces. Cash landraces were intensively exchanged; self-consumption landraces were isolated at the farmer level and prone to genetic drift and complete loss. Merchants exported seeds of cash landraces across Bolivia and into Peru and Argentina. New sexually produced genotypes are less incorporated into cash landraces than in self-consumed landraces. However, new genotypes incorporated into cash landraces are diffused faster and better, being more intensively exchanged. We propose conservation strategies that can be applied to other vegetatively propagated and minor Andean crops. (shrink)

During the nineteenth century, German philosophy developed from a type of general knowledge to an academic discipline at the university. Changes across disciplines to the philosophy of science and psychological surveys created new challenges for the place and purpose of philosophy in the educational system. The content of logic courses for secondary schools (Gymnasiums) was centred on the dissociation of nature and the scale of logic. In this paper, I will examine a number of projects for teaching philosophy at the (...) secondary school level from new humanism to reduce philosophical to philological concerns about different projects offered by Niethammer, Hegel and Herbart. Then, I will focus on the most successful – Adolf Trendelenburg’s Elements of Aristotle’s Logic (1st edition of 1836). This work is a compilation of the logical texts of Aristotle, and for as long as sixty years, it was an official textbook in Prussian secondary schools. The aim of the paper is to show how the rethinking of Aristotle’s heritage affected the theoretical and ideological expectations of propaedeutic courses and transformed the image of logic as a philosophical discipline.

Les zombies sont partout, au cinéma, à la télévision, dans nos rues, chez notre libraire. Grotesques et terrifiants, ils pourraient n’être qu’une tendance kitsch, un divertissement à la mode. Derrière sa démarche traînante et ridicule se cache pourtant une figure symptomatique de notre époque. Peur de l’épidémie ou fantasme de la catastrophe, aliénation moderne ou fascination pour la violence : le zombie et le monde apocalyptique qu’il crée nous parlent d’abord, intimement, de nous-mêmes. Par l’obscène exhibition de la mort, l’ultime (...) tabou de la société occidentale, il brise les limites de la condition humaine : celles de la conscience, de la vie, de la civilisation. Mais surtout, il trahit un fantasme émergeant dans notre culture, celui d’en finir. (shrink)

Traditional approaches describe ethical decision-making of leaders as driven by conscious deliberation and analysis. Accordingly, existing approaches of ethically-oriented leader development usually focus on the promotion of deliberative ethical decision-making, based on normative knowledge and moral reasoning. Yet, a continually growing body of research indicates that a considerable part of moral functions involved in ethical decision-making is automatic and intuitive. In this article, we discuss the implications of this moral intuition approach for the domain of ethically-oriented leader development. Specifically, we (...) introduce a conceptual model and develop a set of theoretical propositions, suggesting that the moral intuition perspective significantly contributes to effective ethically-oriented leader development. The discussion examines theoretical implications and practical applications of the presented propositions and outlines directions for future research. (shrink)

During the Zimbabwean crisis, millions crossed through the apartheid-era border fence, searching for ways to make ends meet. Maxim Bolt explores the lives of Zimbabwean migrant labourers, of settled black farm workers and their dependants, and of white farmers and managers, as they intersect on the border between Zimbabwe and South Africa. Focusing on one farm, this book investigates the role of a hub of wage labour in a place of crisis. A close ethnographic study, it addresses the complex, (...) shifting labour and life conditions in northern South Africa's agricultural borderlands. Underlying these challenges are the Zimbabwean political and economic crisis of the 2000s and the intensified pressures on commercial agriculture in South Africa following market liberalization and post-apartheid land reform. But, amidst uncertainty, farmers and farm workers strive for stability. The farms on South Africa's margins are centers of gravity, islands of residential labour in a sea of informal arrangements.

Faced with hate speech, oppressed groups can use their own speech to respond to their verbal oppressors. This “counterspeech,” however, sometimes itself takes on a hateful form. This paper explores the moral standing of such “hateful counterspeech.” Is there a fundamental moral asymmetry between hateful counterspeech, and the hateful utterances of dominant or oppressive groups? Or are claims that such an asymmetry exists indefensible? I argue for an intermediate position. There _is_ a key moral asymmetry between these two forms of (...) speech. But, this asymmetry notwithstanding, hateful counterspeech is capable of enacting serious harms—and so, contrary to what many legal theorists have argued, it is in principle an appropriate object of legal regulation. I begin by considering the central argument for thinking that hateful counterspeech is not seriously troubling. This argument holds that oppressed groups lack authority—and, by extension, “speaker power.” Yet this argument, I suggest, sits in tension with the fact that low-status members of dominant groups can, through their utterances, seriously harm members of oppressed groups. Philosophers of language have developed sophisticated arguments to explain this last phenomenon: they have argued that speaker power is relativised to particular jurisdictions; that it can be acquired dynamically in local settings; and that it is socially dispersed. I argue that, in light of these arguments, it appears that hateful counterspeech, too, can generate serious harms. Nevertheless, I show that this conclusion is compatible with recognising a crucial moral asymmetry between hateful counterspeech and the hate speech of oppressors. (shrink)

« Falsifier la monnaie », réévaluer les valeurs : telle est la mission que l’oracle de Delphes aurait confiée à Diogène. Rapportée aux personnages du théâtre tragique, à Socrate ou encore à Antisthène, la subversion cynique permet de construire un concept de marginalité pour l’Antiquité grecque.

L’analyse du double emploi du verbe « valoir » dans l’évaluation et l’appréciation éclaircit quelques aspects de la valeur. Évaluer, c’est prendre conscience d’un être qui est valorisé ou valeureux, non d’un être qui a une valeur. La valeur appartient à l’être même d’un objet. Il n’est pas question de demander si celui-ci la possède ou non, de résoudre le problème et de prouver la solution. Toute évaluation est une épreuve : l’objet convainc l’évaluateur en lui révélant la valeur intrinsèque, (...) celle-ci n’est pourtant pas une propriété. (shrink)

The article presents a theoretical analysis of the extramural polemic between Slavoj Žižek and Evald Ilyenkov, undertaken in the context of the search for the foundational underpinnings of the two philosophers’ perspectives on the limit-logical definitions of being. It shows how this apparently “abstract” search grows out of the socio-historical circumstances of the thinkers’ lives, which are inscribed in the dramatic conditions of existence of the political events of the twentieth century. The active life-political position of the follower of Marx’s (...) ideas, figuratively expressed in the text by Lenin’s term “tactics of social democracy” (Lenin 1962), is justified by one or another cognitive position: the unified attitude “not to explain but to transform the world” breaks down into various “tactics” precisely in the attempt to solve the problem of radical negativity (as Žižek formulates it). This is expressed in the division of Marxism into “Western” and “Eastern”. This article analyzes the legitimacy of such a division and shows the conditions for a disintegration of the divide. The relation of Ilyenkov and Žižek to Hegel’s works turns out to be the key to understanding this division, and consequently to the essential difference in socio-political attitudes and “tactics”, of which they are creative representatives. The analysis leads to the formulation of the “germ cell” of disagreement between Ilyenkov and Žižek—the problem of the universal—which unfolds in the difference between the thinkers’ positions on certain theoretical points. The limitation of Ilyenkov’s position, established under the fire of Žižek’s criticism, is removed, according to the author, by the development of a new category of “fractality”, which acts as a counterpart to the main dialectical category of “totality” and provides a concrete (in the Hegelian sense) solution to the problem of radical negativity in the spirit of the classical philosophical tradition.

The notions of perceptual normativity and optimality have generated much discussion in the last decade or so in the literature on Merleau-Ponty. Husserl’s position on the topic has been far less extensively investigated. Surprisingly, however, Husserl wrote a great deal about the question of perceptual optimality. Not only are there a considerable number of important passages scattered throughout the manuscripts, the archive also contains a few important full texts on precisely this issue. Given the role of fulfillment for Husserl’s concept (...) of intentionality, this should not really come as a surprise, since the teleological nature of the fulfillment structure terminates in an experience of the optimum. Hence, however marginal this topic might seem at first glance, reflecting on it rapidly leads us to the heart of Husserl’s project and sheds further light on his conception of intentional experience.

Le présent article s’appuie sur une pratique psychologique dans le cadre de visites médiatisées. Il cible notamment les entretiens cliniques réalisés par le psychologue avec les parents dans l’après-coup des visites médiatisées et a pour objectif de saisir l’enjeu clinique de ces temps d’entretiens. Deux vignettes cliniques permettent d’esquisser les potentialités des rencontres en l’absence des enfants. Il apparaît que ces entretiens favorisent le rétablissement d’une activité de mentalisation et de symbolisation. Enfin, une discussion métapsychologique éclaire les études de cas.
