Deciding between different voluntary movements implies a continuous control of the competition between potential actions. Many theories postulate a leading role of prefrontal cortices in this executive function, but strong evidence exists that a motor region like the primary motor cortex is also involved, possibly via inhibitory mechanisms. This was already shown during the pre-movement decision period, but not after movement onset. For this pilot experiment we designed a new task compatible with the dynamics of post-onset control to study the (...) silent period duration, a pause in electromyographic activity after single-pulse transcranial magnetic stimulation that reflects inhibitory mechanisms. A careful analysis of the SP during the ongoing movement indicates a gradual increase in inhibitory mechanisms with the level of competition, consistent with an increase in mutual inhibition between alternative movement options. However, we also observed a decreased SP duration for high-competition trials associated with change-of-mind inflections in their trajectories. Our results suggest a new post-onset adaptive process that consists in a transient reduction of GABAergic inhibition within M1 for highly conflicting situations. We propose that this reduced inhibition softens the competition between concurrent motor options, thereby favoring response vacillation, an adaptive strategy that proved successful at improving behavioral performance.

Punitive behaviours are often assumed to be the result of an instinct for punishment. This instinct would have evolved to punish wrongdoers and it would be the evidence that cooperation has evolved by group selection. Here, I propose an alternative theory according to which punishment is a not an adaptation and that there was no specific selective pressure to inflict costs on wrongdoers in the ancestral environment. In this theory, cooperation evolved through partner choice for mutual advantage. In the ancestral (...) environment, individuals were in competition to be recruited in cooperative ventures and it was vital to share the benefits of cooperation in a mutually advantageous manner. If individuals took a bigger share of the benefits, their partners would leave them for more interesting partners. If they took a smaller share, they would be exploited by their partners who would receive more than what they had contributed to produce. This competition led to the selection of a sense of fairness, a cognitive adaptation aiming to share equally the benefits of cooperation in order to attract partners. In this theory, punishment is not necessary for the evolution of cooperation. Punitive behaviours are only a way to restore fairness by compensating the victim or penalizing the culprit. Drawing on behavioural economics, legal anthropology, and cognitive psychology, I show that empirical data fit better with this framework than with the theory of group selection. When people punish, they do so to restore fairness rather than to help the group. (shrink)

This paper intends to bring Austinian themes into methodological discussion about models. Using Austinian conceptual vocabulary, I argue that models perform actions in and outside of the academic field. This multiplicity of fields induces a variety of felicity conditions and types of performed actions. If for example, an inference from a model is judged according to some epistemological criteria in the scientific field, the representation of the world which the model carries will not be judged by the same criteria outside (...) the scientific field. A model can be considered as a standard in a strict scientific framework, while not being used as part of public policies, or vice versa. However, we focus on the dynamics between different fields.

High and low alexithymia scorers were confronted with a modified visual oddball task that allowed the study of categorical perception of emotional expressions on faces. Participants had to quickly detect a deviant (rare) morphed face that shared or did not share the same emotional expression as the frequent one. Expected categorical perception effects, which were also neurophysiologically indexed, showed that rare stimuli were detected faster if they depicted a different emotional expression compared to rare stimuli depicting the same emotional expression (...) than the frequent one. Even if no differences were observed at a behavioural level, high alexithymia scorers evidenced overall delayed neurophysiological responses in components related to the attentional processing of rare emotional faces. Moreover, the categorical perception effects for event-related components associated with the attentional processing were smaller in high alexithymia scorers and were even absent for anger. These results show that high alexithymia scorers present discrimination delays that are already observed at the attentional level. (shrink)

Since the Industrial Revolution, human societies have experienced high and sustained rates of economic growth. Recent explanations of this sudden and massive change in economic history have held that modern growth results from an acceleration of innovation. But it is unclear why the rate of innovation drastically accelerated in England in the eighteenth century. An important factor might be the alteration of individual preferences with regard to innovation resulting from the unprecedented living standards of the English during that period, for (...) two reasons. First, recent developments in economic history challenge the standard Malthusian view according to which living standards were stagnant until the Industrial Revolution. Pre-industrial England enjoyed a level of affluence that was unprecedented in history. Second, behavioral sciences have demonstrated that the human brain is designed to respond adaptively to variations in resources in the local environment. In particular, Life History Theory, a branch of evolutionary biology, suggests that a more favorable environment should trigger the expression of future-oriented preferences. In this paper, I argue that some of these psychological traits – a lower level of time discounting, a higher level of optimism, decreased materialistic orientation, and a higher level of trust in others – are likely to increase the rate of innovation. I review the evidence regarding the impact of affluence on preferences in contemporary as well as past populations, and conclude that the impact of affluence on neurocognitive systems may partly explain the modern acceleration of technological innovations and the associated economic growth.

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants’ horizontal, pair‐wise interactions led (...) “bottom up” to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community‐evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.

Sometimes physicians lie to third-party payers in order to grant their patients treatment they would otherwise not receive. This strategy, commonly known as gaming the system, is generally condemned for three reasons. First, it may hurt the patient for the sake of whom gaming was intended. Second, it may hurt other patients. Third, it offends contractual and distributive justice. Hence, gaming is considered to be immoral behavior. This article is an attempt to show that, on the contrary, gaming may sometimes (...) be a physician's duty. Under specific circumstances, gaming may be necessary from the viewpoint of the internal morality of medicine. Moreover, the objections against gaming are examples of what we call the idealistic fallacy, that is, the fallacy of passing judgments in a nonideal world according to ideal standards. Hence, the objections are inconclusive. Gaming is sometimes justified, and may even be required in the name of beneficence. (shrink)

If panpsychism is true, it suggests that consciousness pervades not only our brains and bodies but also the entire universe, prompting a reevaluation of our existential attitudes. Hence, panpsychism potentially fulfills psychological needs typically addressed by religious beliefs, such as a sense of belonging and purpose but also transcendence. The discussion is organized into two main areas: the implications of panpsychism for basic human existential needs, such as feelings of kinship, ommunication, and loneliness; and for greater existential questions relating to (...) mystical experiences including transcendent unity and alleviation of the fear of death. In conclusion panpsychism may provide a deeper meaning in life for some people but its broader impact depends on individual dispositions and the cultural context in which it is embedded. (shrink)

Le présent article revient sur le dernier ouvrage de Thomas Piketty, Capital et idéologie (2019). Nous commençons par inscrire l’ouvrage dans l’argument développé par l’auteur dans ses précédents ouvrages, avant d’en souligner un certain nombre de limites. Nous questionnons d’abord la manière dont Piketty pense le capitalisme, avant d’en venir à sa théorie de l’idéologie. Enfin, nous tenterons de définir les contours et limites du projet de dépassement du capitalisme de Piketty, c’est-à-dire sa vision d’une société juste, d’un « socialisme (...) participatif », développée au dernier chapitre de l’ouvrage.

Résumé L’influence des discours théoriques sur leur objet d’étude est une particularité propre aux sciences sociales : le simple fait de formuler un discours sur le monde social entraîne des changements au sein de ce dernier. En économie, ce phénomène a fait l’objet de traitements variés. Récemment, une frange de la sociologie économique a pris le parti d’étudier le monde économique comme encastré dans la science qui l’étudie. Auparavant, certains grands noms la discipline économique s’étaient déjà penchés sur le sujet. (...) Ce travail a pour objectif d’éclaircir ces deux cheminements de pensée ayant le même objet, d’en identifier les principales différences et d’expliquer ces dernières par des problématiques de départ distinctes. Nous identifierons, dans la lignée de ce qui a pu être fait en économie des conventions, une approche stratégique de l’influence des discours théoriques (celle des économistes), et une approche interprétative (celle des sociologues).

Interest in the computational aspects of modeling has been steadily growing in philosophy of science. This paper aims to advance the discussion by articulating the way in which modeling and computational errors are related and by explaining the significance of error management strategies for the rational reconstruction of scientific practice. To this end, we first characterize the role and nature of modeling error in relation to a recipe for model construction known as Euler’s recipe. We then describe a general model (...) that allows us to assess the quality of numerical solutions in terms of measures of computational errors that are completely interpretable in terms of modeling error. Finally, we emphasize that this type of error analysis involves forms of perturbation analysis that go beyond the basic model-theoretical and statistical/probabilistic tools typically used to characterize the scientific method; this demands that we revise and complement our reconstructive toolbox in a way that can affect our normative image of science.

This article aims at understanding how "ethical public issues" are created, and dealt within a public arena. Here, we view ethical public issues as social constructs, which are the results of issue framing contests. Such an approach will enable us to understand how ethical public issues emerge and are shaped by strategizing actors (including firms, NGOs, the media, and governments), in an attempt to impose their own definition and preferred solution to the issue. We also propose key factors which explain (...) the success of a framing attempt, and evidence of such success. The empirical case of the labor conditions in West Africa's cocoa industry is used to illustrate this theoretical framework and methodological approach. (shrink)

This paper explores the role of iconicity in spoken language and other human communication systems. First, we concentrate on graphical and gestural communication and show how semantically motivated iconic signs play an important role in creating such communication systems from scratch. We then consider how iconic signs tend to become simplified and symbolic as the communication system matures and argue that this process is driven by repeated interactive use of the signs. We then consider evidence for iconicity at the level (...) of the system in graphical communication and finally draw comparisons between iconicity in graphical and gestural communication systems and in spoken language.

Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs. Yet, can indeterminism affect also the past, making it open as well? We show that by upholding principles of finiteness of information one can entail such a possibility. We provide a toy model that shows how the past could be fundamentally indeterminate, while (...) also explaining the intuitive (and observed) asymmetry between the past—which can be remembered, at least partially—and the future—which is impossible to fully predict.

In the literature on medical ethics, it is generally admitted that vulnerable persons or groups deserve special attention, care or protection. One can define vulnerable persons as those having a greater likelihood of being wronged – that is, of being denied adequate satisfaction of certain legitimate claims. The conjunction of these two points entails what we call the Special Protection Thesis. It asserts that persons with a greater likelihood of being denied adequate satisfaction of their legitimate claims deserve special attention, (...) care or protection. Such a thesis remains vague, however, as long as we do not know what legitimate claims are. This article aims at dispelling this vagueness by exploring what claims we have in relation to health care – thus fleshing out a claim-based conception of vulnerability. We argue that the Special Protection Thesis must be enriched as follows: If individual or group X has a greater likelihood of being denied adequate satisfaction of some of their legitimate claims to physical integrity, autonomy, freedom, social provision, impartial quality of government, social bases of self-respect or communal belonging, then X deserves special attention, care or protection. With this improved understanding of vulnerability, vulnerability talk in healthcare ethics can escape vagueness and serve as an adequate basis for practice. (shrink)

Despite being one of the most dependable methods used by applied mathematicians and engineers in handling complex systems, the finite element method commits variational crimes. This paper contextualizes the concept of variational crime within a broader account of mathematical practice by explaining the tradeoff between complexity and accuracy involved in the construction of numerical methods. We articulate two standards of accuracy used to determine whether inexact solutions are good enough and show that, despite violating the justificatory principles of one, the (...) finite element method nevertheless succeeds in obtaining its legitimacy from the other.

In Nietzsche's "mature" texts, we are witnessing a complete dissolution of the subject. At first glance, however, this appears highly paradoxical (Wotling 2015), leading some commentators to suggest that there is a real contradiction in Nietzsche's work (Gardner 2009), insofar as the author never ceases to speak of himself and at the same time invites his reader to become who he is. Are we to understand, then, that any self is illusory and constitutes a metaphysical illusion, i.e., that the becoming (...) in which we are always caught according to Nietzsche must make any position of a self impossible, and at the very least diminishing? Following in the footsteps of Alexander Nehamas (1985), we believe that we can overcome the contradiction identified by S. Gardner by showing that Nietzsche's conception of the self is not "realistic", but precisely also fictional and dynamically positive at the same time. (shrink)

En el presente artículo se propone una ética de la donación a partir de la idea de donación en la fenomenología de Jean Luc Marion, junto a la noción de la acción no recíproca en Kant y la noción de don y gratuidad en Santo Tomás de Aquino. La intención de Marion es liberar al fenómeno de cualquier condición subjetiva que se le imponga; es decir, intenta darle la prioridad a los fenómenos y comprenderlos como lo que se da. De (...) ahí es que teoriza sobre el don y la donación, cuya particularidad es que están libres del intercambio y la deuda. Similarmente, que Kant afirma que el bien debe hacerse sin esperar algo a cambio, mientras que Santo Tomás afirma que el don es hacer el bien gratuitamente. Por eso se puede proponer una ética de la donación cuyos pilares fundamentales son: gratuidad, desinterés, no reciprocidad, libertad, entrega generosa, compasión y responsabilidad afectiva. (shrink)

There is widespread consensus among policymakers that climate change and digitalisation constitute the most pressing global transformations shaping human life in the 21st century. Seeking to address the challenges arising at this juncture, governments, technologists and scientists alike increasingly herald artificial intelligence (AI) as a vehicle to propel climate change mitigation and adaptation. In this paper, we explore the intersection of digitalisation and climate change by examining the deployment of AI in government-led climate action. Building on participant observations conducted in (...) the context of the “Civic Tech Lab for Green”—a government-funded public interest AI initiative—and eight expert interviews, we investigate how AI shapes the negotiation of environmental sustainability as an issue of public interest. Challenging the prescribed means–end relationship between AI and environmental protection, we argue that the unquestioned investment in AI curtails political imagination and displaces discussion of climate “problems” and possible “solutions” with “technology education”. This line of argumentation is rooted in empirical findings that illuminate three key tensions in current coproduction efforts: “AI talk vs. AI walk”, “civics washing vs. civics involvement” and “public invitation vs. public participation”. Emphasising the importance of re-exploring the innovative state in climate governance, this paper extends academic literature in science and technology studies that examines public participation in climate change adaptation by shedding light on the emergent phenomenon of public interest AI.

It is commonly assumed that moral deliberation requires that the alternatives available in a choice situation are evaluatively comparable. This comparability assumption is threatened by claims of incomparability, which is often established by means of the small improvement argument (SIA). In this paper I argue that SIA does not establish incomparability in a stricter sense. The reason is that it fails to distinguish incomparability from a kind of evaluative indeterminacy which may arise due to the vagueness of the evaluative comparatives (...) ‘better than,’ ‘worse than,’ and ‘equally as good as.’.

This paper articulates an account of imperatives that sensibly supports the idea of a logic of imperative inferences. We rebuke common objections to the very possibility of such a logic, from a perspective based on recent linguistic work on the morphosyntax of imperatives. Specifically, we develop the notion that the content of an imperative sentence includes both a force operator alongside an imperational content to which the force applies. We further argue that this account of the content of imperatives constitutes (...) a plausible and flexible framework to develop a logic of imperative by examining a number of reconstructions of this idea using semantical analogs of widespread modal semantics. After studying the performance of those approaches, we conclude that progress in imperative logic has been hindered by the failure to adopt conflict-tolerant and resource-sensitive semantics, but suggest that such considerations can be incorporated in this flexible framework. Finally, we also propose a simple account of the difference between operators applying to the content of imperatives and imperative operators, in a way that sheds light on some of the issues underlying the usual antinomies.

Resumen: El presente trabajo explora el estatuto del arte en la filosofía de Spinoza, en el marco de la inversión copernicana que da origen a la estética y del barroco holandés. Si bien el pensamiento spinozista se inscribe en la conversión antropológica, en donde lo bello resulta ser un efecto en el sujeto y no una cualidad de los objetos, su comprensión del arte es inasimilable a la “estética” como ámbito diferenciado y autónomo que se consolida en el siglo XVIII, (...) y más bien concibe el arte integrado a la vida y a la experiencia común -a la vez que, en cuanto praxis de origen corporal al alcance de cualquiera, presenta puntos de contacto con las vanguardias históricas del siglo XX-. Spinoza, según se propone en este texto, concibe la producción de “obras de arte” menos como un hecho estético que como una actividad corporal éticamente orientada a la vida buena.: The present work explores the status of art in the philosophy of Spinoza, within the framework of the Copernican revolution that gives rise to aesthetics and the Dutch Baroque. Although the Spinozist thought is inscribed in the anthropological conversion by virtue of which beauty turns out to be an effect on the subject and not a property of objects, its understanding of art is unassimilable to "aesthetics" as a differentiated and autonomous area that it was consolidated in the eighteenth century, and rather conceived art integrated to life and common experience -at the same time, as praxis of bodily origin within the reach of anyone, presents points of contact with the historical avant-gardes of the twentieth century-. Spinoza conceives the production of "artworks" less as an aesthetic fact than as a body activity ethically oriented to the good life. (shrink)

Le génocide du Rwanda constitue l'un des événements majeurs du xxe siècle : 800 000 Tutsis et Hutus de l'opposition au « gouvernement intérimaire » rwandais ont été massacrés entre avril et juin 1994. Or, la reconnaissance de ce génocide ne va pas de soi. Cet article analyse les « contre-feux interprétatifs » mis en place selon trois axes : négation du génocide, euphémisation en « guerre tribale », thèse du « double génocide ». La presse dans cette guerre de (...) mémoire a été un vecteur tout à fait essentiel. The genocide in Rwanda was one of the major events of the 20th century: 800, 000 Tutsis and Hutus opposing Rwanda's "interim government" were massacred between April and June 1994. But recognition of this genocide is by no means taken for granted. This article analyses the different interpretations that were brought in to deflect the issue, such as genocide denial, euphemistic references to the genocide as "tribal war­fare" and "double genocide" theory. The role of the press in this "war over memory" was crucial. (shrink)

“De l’information du poème” qui clôt la partie “Éléments” dans Poétique de la Relation, représente pour le lectorat habitué à l'écriture glissantienne un chapitre assez surprenant voire confondant tant au niveau de l’approche du sujet traité que de sa mise en forme rhétorique, car c’est autour de l’opposition entre poésie et informatique que démarre son propos. Tout d’abord, on a l’impression que Glissant s'écarte des riches lieux-communs qui rythment et structurent sa pensée puisque, après quelques pages consacrées au baroque, son (...) attention se tourne ici de manière apparemment aléatoire vers l'antagonisme entre les nouvelles technologies et le parangon de la création littéraire. L'intérêt de Glissant pour la science et les nouvelles technologies n’est certes pas une anomalie lorsque l’on considère l’ensemble de son œuvre puisque cette dernière est en effet bâtie sur un éclectisme quasi programmatique qui se manifeste à travers la pensée du rhizome et le droit à l'opacité. Cependant, la dichotomie entre “ces deux ordres de la connaissance, le poétique et le scientifique” sur laquelle repose l'hypothèse de ce court chapitre semble trancher avec la rhétorique relationnelle qui caractérise son approche. Le penseur semble même souscrire aux poncifs d’un discours d'époque réduisant la complexité des nouvelles technologies et la magnitude de leurs effets sur la société contemporaine à une simple série d’oppositions entre, d’une part, une culture humaniste qui rassemblerait une communauté en présence autour de la parole poétique menacée, et, d’autre part, le pouvoir aliénant de l’information transmise à travers des circuits non-relationnels, impersonnels, sans voix et sans visage.

Science is the practice that provides the most epistemically warranted claims that can be made, and involves the possibility that explanatory theories will eventually be replaced by better ones. In the case of Psychology, the process of formulating theories through the scientific method has been difficult and has generated concern among scientific psychologists. Thus, in 1978 Meehl published a seminal text about the weakness of psychological theories, which has had a great influence to this day, with different authors describing a (...) theoretical crisis in Psychology. This manuscript reviews the current panorama of the situation, characterizing the crisis, the associated factors and the proposals to solve it. In relation to the factors associated with the crisis, the youth of Psychology, the emphasis on data, problems in the definitions of constructs and their measurement, and difficulties in determining causality in Psychology are highlighted. With respect to the solutions, the proposals for including training in theory construction in the study plans, the integration of interdisciplinary skills, the theory formation cycle, and the formation of theories are reviewed. It is concluded about the need to include theoretical training within university curricula, as well as the possibility that Theoretical Psychology is a viable specialization for psychologists.

We introduce a logic specifically designed to support reasoning about social choice functions. The logic includes operators to capture strategic ability, and operators to capture agent preferences. We establish a correspondence between formulae in the logic and properties of social choice functions, and show that the logic is expressively complete with respect to social choice functions, i.e., that every social choice function can be characterised as a formula of the logic. We prove that the logic is decidable, and give a (...) complete axiomatization. To demonstrate the value of the logic, we show in particular how it can be applied to the problem of determining whether a social choice function is strategy-proof. (shrink)

The causal view of categories assumes that categories are represented by features and their causal relations. To study the effect of causal knowledge on categorization, researchers have used Bayesian causal models. Within that framework, categorization may be viewed as dependent on a likelihood computation (i.e., the likelihood of an exemplar with a certain combination of features, given the category's causal model) or as a posterior computation (i.e., the probability that the exemplar belongs to the category, given its features). Across three (...) experiments, in combination with computational modeling, we offer evidence that categorization is better accounted for by assuming that people compute posteriors and not likelihoods, though both probabilities are closely related. This result contrasts with existing analyses of causal-based categorization, which assume that likelihood computations give a good approximation of human judgments. We also find that people are able to compute likelihoods in a closely related task that elicits judgments of consistency rather than category membership judgments. Our analyses show that people do use causal probabilistic information as prescribed by a Bayesian model but that they flexibly compute likelihoods or posteriors depending on the task. We discuss our results in relation to the relevant literature on the topic. (shrink)
