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)

Background: There is increasing evidence to support the efficacy of transcranial direct current stimulation applications in cognitive augmentation and rehabilitation. Neuromodulation achieved with tDCS may further regulate regional cerebral perfusion affiliated through the neurovascular unit; however, components of cerebral perfusion decrease across aging. A novel neuroimaging approach, functional near-infrared spectroscopy, can aid in quantifying these regional perfusional changes. To date, the interaction of the effects of tDCS on cognitive performance across the lifespan and obtained fNIRS hemodynamic responses remain unknown.Objective: This (...) review aims to examine the effects of tDCS on cognitive performance and fNIRS hemodynamic responses within the context of cognitive aging.Methods: Six databases were searched for studies. Quality appraisal and data extraction were conducted by two independent reviewers. Meta-analysis was carried out to determine overall and subgroup effect sizes.Results: Eight studies met inclusion criteria. The overall effect size demonstrates that tDCS can alter cognitive performance and fNIRS signals, with aging being a potential intermediary in tDCS efficacy.Conclusion: From the studies included, the effects of tDCS on cognitive performance and fNIRS metrics are most prominent in young healthy adults and appear to become less robust with increasing age. Given the small number of studies included in this review further investigation is recommended. (shrink)

In this paper, elementary but hitherto overlooked connections are established between Wittgenstein's remarks on mathematics, written during his transitional period, and free-variable finitism. After giving a brief description of theTractatus Logico-Philosophicus on quantifiers and generality, I present in the first section Wittgenstein's rejection of quantification theory and his account of general arithmetical propositions, to use modern jargon, as claims (as opposed to statements). As in Skolem's primitive recursive arithmetic and Goodstein's equational calculus, Wittgenstein represented generality by the use of free (...) variables. This has the effect that negation of unbounded universal and existential propositions cannot be expressed. This is claimed in the second section to be the basis for Wittgenstein's criticism of the universal validity of the law of excluded middle. In the last section, there is a brief discussion of Wittgenstein's remarks on real numbers. These show a preference, in line with finitism, for a recursive version of the continuum. (shrink)

Whistle-blowing is generally considered from the viewpoint of professional morality. Morality rejects the idea of choice and the interests of the professional as immoral. Yet the dreadful retaliations against the messengers of the truth make it necessary for morality to leave a way out of whistle-blowing. This is why it forges rights (sometimes called duties) to trump the duty to the public prescribed by professional codes. This serves to hide the obvious fact that whether to blow the whistle is indeed (...) a choice, not a matter of objective duty. One should also notice that if it fails to achieve anything then blowing the whistle was the wrong decision (or maybe the right decision that nobody would want to make). There is nevertheless a tendency to judge it based on the motivation of the whistle blower. In a way, whistle blowers should strive to act like saints. Yet, it is logically impossible to hold both whistle-blowing as mandatory and whistle-blowers as heroes or saints. Moreover, this tends to value the great deeds of a few over the lives of the many, which is incompatible with the basic assumptions of morality. But consistency is not a main feature of professional morality. (shrink)

The cumulative open-endedness of human cultures represents a major break with the social traditions of nonhuman species. As traditions are altered and the modifications retained along the cultural lineage, human populations are capable of producing complex traits that no individual could have figured out on its own. For cultures to produce increasingly complex traditions, improvements and modifications must be kept for the next generations to build upon. High-fidelity transmission would thus act as a ratchet, retaining modifications and allowing the historical (...) buildup of complex traditions. Mechanisms acting against slippage are important, of course, but cultures also need to move forward for the ratchet to retain anything important. In this article, I argue that studies of modification-generating processes and the many ways they shape cumulative culture have been overlooked. Key to a better understanding of cultural modification processes is taking seriously that cultural traditions consist of complex, hierarchically structured recipes. Taking such structures seriously and assessing the different ways they can vary in cultural design space, a novel picture for the onset of cumulative cultural evolution emerges. I argue that a possible impediment for cumulative culture in nonhuman animals may in fact reside not so much in the fidelity of their social transmission but rather in the constraints, internal and external, on their capacity to modify complex, hierarchically structured cultural recipes.

Les archives, bien que fondamentales dans la pratique des historiens, tiennent une faible place dans leur réflexion épistémologique, alors que la notion, employée le plus souvent au singulier, a été davantage analysée par certains philosophes, dont en dernier lieu Paul Ricoeur. Il s'agira donc de comprendre l'usage que ce dernier fait du concept d'archive dans son dernier ouvrage, La Mémoire, l'histoire, l'oubli, puis de montrer sa filiation avec les travaux de Michel Foucault et de Michel de Certeau. Enfin, on voudrait (...) montrer en quoi cette« archive», liée intimement à la notion de témoignage, peut conduire à des difficultés du point de vue de l'épistémologie historique, et qu'il semble possible de lui opposer un autre usage de la notion, soucieux d'en souligner l'historicité et la matérialité face à une interprétation plus textuelle et herméneutique.

Cultural evolutionists typically emphasize the informational aspect of social transmission, that of the learning, stabilizing, and transformation of mental representations along cultural lineages. Social transmission also depends on the production of public displays such as utterances, behaviors, and artifacts, as these displays are what social learners learn from. However, the generative processes involved in the production of public displays are usually abstracted away in both theoretical assessments and formal models. The aim of this paper is to complement the informational view (...) with a generative dimension, emphasizing how the production of public displays both enable and constrain the production of modular cultural recipes through the process of innovation by recombination. In order to avoid a circular understanding of cultural recombination and cultural modularity, we need to take seriously the nature and structure of the generative processes involved in the maintenance of cultural traditions. A preliminary analysis of what recombination and modularity consist of is offered. It is shown how the study of recombination and modularity depends on a finer understanding of the generative processes involved in the production phase of social transmission. Finally, it is argued that the recombination process depends on the inventive production of an interface between modules and the complex recipes in which they figure, and that such interfaces are the direct result of the generative processes involved in the production of these recipes. The analysis is supported by the case study of the transition from the Oldowan to the Early Acheulean flake detachment techniques. (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)

Abstract: This paper considers the question of whether it is possible to be mistaken about the content of our first-order intentional states. For proponents of the rational agency model of self-knowledge, such failures might seem very difficult to explain. On this model, the authority of self-knowledge is not based on inference from evidence, but rather originates in our capacity, as rational agents, to shape our beliefs and other intentional states. To believe that one believes that p, on this view, constitutes (...) one's belief that p and so self-knowledge involves a constitutive relation between first- and second-order beliefs. If this is true, it is hard to see how those second-order beliefs could ever be false.I develop two counter-examples which show that despite the constitutive relation between first- and second-order beliefs in standard cases of self-knowledge, it is possible to be mistaken, and even self-deceived, about the content of one's own beliefs. These counter-examples do not show that the rational agency model is mistaken—rather, they show that the possibility of estrangement from one's own mental life means that, even within the rational agency model, it is possible to have false second-order beliefs about the content of one's first-order beliefs. The authority of self-knowledge does not entail that to believe that one believes that p suffices to make it the case that one believes that p. (shrink)

Jan Patočka is usually connected with Czech dissidence, a political movement which stood up against the communist government. We want to defend the hypothesis that the notion of dissidence is not originally a political one but, above all, a phenomenological one. Dissidence is a movement of distancing which implies a rootedness, and this movement of distancing is peculiar to human beings. Patočka calls “movement of human existence” this paradoxical rootedness which is an extramundane and mundane position. Thus, we have to (...) review the theory of the three movements of human existence. While it is tempting to separate the third movement, as a movement of transcendence, and to describe it as a political dissidence, we would like to show that the three movements, have to be understood as Dissidence.

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)

Of the various discourses reported by Thucydides, one of the most studied and interpreted is the speech of Diodotus in the Mytilenian debate. The importance of this speech stems from its depth and the fact that it touches on a large number of issues central to any kind of political reflection, such as the role of justice, the place of force and law in a political community, and the relationship between democracy and empire. But do the various studies and interpretations (...) encompass the entire potential for reflection on this subject? The answer is no. Abounding with questions, problems, and reflections, this speech deserves a new reading, one that sets off its deep meaning in the clearest and most precise way. To accomplish this task, the author begins by presenting the context of the discourse, and then describes Leo Strauss's interpretation, centred on the natural right and Diodotus’ supposed authorship of this concept. The article goes on to analyse the Castoriadis seminars on ancient Greece at EHESS, arguing for a very different reading, in which Diodotus is presented as a follower of the traditional Athens thinking. Lastly, the author shows the limits of these interpretations, revealing Diodotus to be a first-rate politician who proposed a new Athenian policy – a policy that seeks to align the empire with democracy by founding a new political institution that goes beyond narrow limits of the city.

New and highly effective treatments against hepatitis C have come on the market in recent years. Their high cost has sparked vociferous debate concerning drug price control, the state’s responsibility towards infected populations and the power of multinational pharmaceutical companies. One possible way to understand these debates is to take into account the particular effects of pharmaceutical capitalism upon the circulation of commodities. Recent protests related to access to treatment identify circulation of medicines as an increasing site of capital accumulation (...) and conflicts. This article defines the notion of ‘logistic regimes’ and shows how such regimes are contested. It analyzes critical ways of engaging with contemporary pharmaceutical logistics, through variations on medical tourism, critiques of patenting and pricing practices, and organization of alternative supply routes. It further proposes to deepen the notion of diversion as a political concept describing specific forms of opposition to the management practices of logistical capitalism. (shrink)

La thèse que présuppose ce livre est la suivante : la modernité, que l'on dit "désenchantée", est triste, parce que désenchantée. Les textes qui y sont rassemblés veulent mettre en présence, mais aussi en question, les deux sens du mot "désenchantement" : l'idée que l'avancement de la "raison instrumentale" (C Taylor)s'est accompagné du recul du domaine du magique, du merveilleux, du mythe, et celle selon laquelle la modernité est morose. Mais il s'agit ici de penser moins la morosité que la (...) joie liée à ce que pourrait être une philosophie du réenchantement du monde. Non pas tant, donc, replonger dans les thèses sur le désenchantement qu'imaginer ce que pourrait être un certain réenchantement. A cet égard, on a voulu porter un regard privilégié sur l'enfance, "terre de l'humain" (T De Koninck), comme sur une manière d'idéal qui pointerait vers la question du sens d'une existence qui vaille d'être vécue. Le pari de ce projet est en définitive qu'une philosophie du réenchantement du monde témoignera que la vie peut être une aventure exaltante, passionnante, un parcours sensé et par conséquent rempli d'espoir, comme dans ces contes pour enfants qui jadis faisaient notre joie.

This paper presents the first compositional semantics for if then conditionals. The semantics of each element are first examined separately. The meaning of if is modeled according to a possible worlds semantics. The particle then is analyzed as an anaphoric word that places its focused element inside the context settled by a previous element. Their meanings are subsequently combined in order to provide a formal semantics of if A then C conditionals, which differs from the simple if A, C form. (...) This semantics has the particularity of validating contraposition for the first type but invalidating it for the second type. Finally, a detailed examination of the sentences presented in the literature opposing this schema of reasoning shows that these counterexamples do not generally concern if then conditionals but, rather, even if conditionals and that contraposition is therefore a valid means of reasoning with regard to if then conditionals in natural language, as this system predicts.

Predicates within many conceptual classes are intuited as mutually exclusive. Based on these predicates’ interaction with logical vocabulary like _and_ or _also_, however, this paper argues that they are in fact underlyingly consistent; the strong intuited meanings arise from semantic exhaustification. In addition to demonstrating that exhaustification is more widespread than previously believed, this paper also shows that this particular exhaustification effect behaves in a hitherto undescribed manner. Indeed, a predicate’s exhaustification is always computed locally at the level of the (...) predicate, rather than the clause or sentence containing it. (shrink)

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 case study presented by Winch and Sinnott (2011) shows not only how difficult it is for clinicians and researchers to identify conflicts of interest (COI), but also how damaging it can be when there are unin- formed and uncoordinated policy responses by senior administrators.

Plagiarism is a crime against academy. It deceives readers, hurts plagiarized authors, and gets the plagiarist undeserved benefits. However, even though these arguments do show that copying other people’s intellectual contribution is wrong, they do not apply to the copying of words. Copying a few sentences that contain no original idea (e.g. in the introduction) is of marginal importance compared to stealing the ideas of others. The two must be clearly distinguished, and the ‘plagiarism’ label should not be used for (...) deeds which are very different in nature and importance. (shrink)

What may we learn about the life of human beings with Evolutionary Biology? In order to answer this question, without taking a distrustful stance, I think that Daniel Dennett’s evolutionary cognitivism and Foucault s archaeological approach are not unreconciliable but complementary traditions. Indeed, Derrnett’s originality, thanks to his interpretation of the Baldwin Effect and his thesis of Self as a Narrative Center of Gravity, manages to present the human being’s world as the living fulfilment of a set of historical products, (...) without giving up the properly creative dimension of the individual . In this way, devices of domination and processes of « subjectivisation » belong to the broader transfornzative process of the evolution of life on Earth. In return, Dennett s philosophy, rightfully careful when it comes to political questions, should be complemented by a critical analysis. (shrink)
