Ramsey’s theorem asserts that every k-coloring of $[\omega ]^n$ admits an infinite monochromatic set. Whenever $n \geq 3$, there exists a computable k-coloring of $[\omega ]^n$ whose solutions compute the halting set. On the other hand, for every computable k-coloring of $[\omega ]^2$ and every noncomputable set C, there is an infinite monochromatic set H such that $C \not \leq _T H$. The latter property is known as cone avoidance.In this article, we design a natural class of Ramsey-like theorems encompassing (...) many statements studied in reverse mathematics. We prove that this class admits a maximal statement satisfying cone avoidance and use it as a criterion to re-obtain many existing proofs of cone avoidance. This maximal statement asserts the existence, for every k-coloring of $[\omega ]^n$, of an infinite subdomain $H \subseteq \omega $ over which the coloring depends only on the sparsity of its elements. This confirms the intuition that Ramsey-like theorems compute Turing degrees only through the sparsity of its solutions. (shrink)

This essay investigates the way in which Wolff takes an interest in the hypothesis of an emendatio of the prima philosophia from Leibniz’s incitement in De primae philosophiae emendatione, et de notione substantiae (1694) to re-found metaphysics. This makes it possible, secondly, to examine the way in which Wolff takes Johannes Clauberg’s ontology as a model, even though it represents in his view only a failed attempt at that same emendatio. Through the analysis of the texts, this article considers the (...) possibility of a new reading of the ‘failure’ attributed by Wolff to Clauberg, which would consist in his having ‘emended’ first philosophy by expelling it from the domain of ontology and finally identifying it with Cartesian prima philosophia.

The knowledge representation and reasoning of both humans and artificial systems often involves conditionals. A conditional connects a consequence which holds given a precondition. It can be easily recognized in natural languages with certain key words, like “if” in English. A vast amount of literature in both fields, both artificial intelligence and psychology, deals with the questions of how such conditionals can be best represented and how these conditionals can model human reasoning. On the other hand, findings in the psychology (...) of reasoning, such as those in the Suppression Task, have led to a paradigm shift from the monotonicity assumptions in human inferences towards nonmonotonic reasoning. Nonmonotonic reasoning is sensitive for information change, that is, inferences are drawn cautiously such that retraction of previous information is not required with the addition of new information. While many formalisms of nonmonotonic reasoning have been proposed in the field of Artificial Intelligence, their capability to model properties of human reasoning has not yet been extensively investigated. In this paper, we analyzed systematically from both a formal and an empirical perspective the power of formal nonmonotonic systems to model possible explicit defeaters, as in the Suppression Task, and more implicit conditional rules that trigger nonmonotonic reasoning by the keywords in such rules. The results indicated that the classical evaluation for the correctness of inferences has to be extended in the three major aspects regarding the inference system, the knowledge base, and possible assumed exceptions for the rule.

In this article, I show and discuss the relevance of Wittgenstein's arguments as to the spatial structure of sight to recent issues in the philosophy of mind. The first, bearing upon the dimensionality of the manifolds at play in depiction, plays a critical role in Clark's attempt to provide an independent account ofqualiaand of their differentiative properties. The second, pertaining to the properly spatial structure formed by the data of sight, is explicitly appealed to in the debate on the realistic (...) character of any genuinely spatial scheme. I argue that if Wittgenstein rightly assumes that the simultaneous presence of sensible places in vision is a key condition for objectivity, he fails nevertheless to warrant the allegedly realistic character of the scheme employed in his own search for a phenomenological description of the visual field.

Using semantic and syntactic methods, we prove the compatibility of the truth of universally quantified slurring sentences of the form [all Ss are Ns] or [all Ss are S*s] with the existential core of moral and semantic innocence. We also show that proving their mutual compatibility by means of logic leaves untouched the moral problem tied to their material truth. Finally, we trace the problem back to the failure to signal in the spelling of the slurring term’s meaning that the (...) derogatory concept it denotes is not universally accepted. (shrink)

A recent study by P.R. Blum suggests the hypothesis of an ideal line from Scotus to Mastri, passing through Perera, which would tend towards a new concept of metaphysics attainable through the use of abstraction by indifference. This essay intends to test this hypothesis starting from the way in which Perera questions the unity of metaphysical abstraction through a series of innovative interpretations that are widely received in both Catholic and Reformed and Protestant domains. A first interpretation, less radical, advances (...) a model of metaphysical abstraction, taken up by Mastri and Micraelius, which maintains the unity of metaphysics; a second interpretation, more radical, breaks the methodological unity of metaphysics through a clear distinction between ‘real’ abstraction from matter (secundum rem et rationem) and ‘mental’ abstraction by indifference (secundum rationem tantum) and, consequently, between metaphysics and ontology.

Iniciando pela caracterização clássica de intencionalidade proporcionada por Brentano, nós fazemos uma revisão crítica da proposta enativista radical com relação à cognição básica no intuito de mostrar que o pressuposto de que nada ficaria perdido com a remoção dos compromissos representacionalistas da teleosemântica é injustificado. Argumentamos que algumas características importantes da cognição básica ficam perdidas com a RE(C)tificação da teleosemântica, as quais resgatamos pelo esboço de uma alternativa cunhada atributivismo-de-conteúdo livre de compromissos metafísicos.

Publié initialement en 1982, l’ouvrage de Marco Bianchini Alle origini della scienza economica : felicita pubblica e matematica sociale negli economisti italiani del settecento (1711-1803) est désormais accessible au public français dans une traduction proposée par Pierre Crépel. En première approximation, ce travail a le grand mérite d’interroger quelques pratiques traditionnelles de l’histoire de la pensée économique. Il rappelle opportunément que des épisodes significatifs, révolutionnaire..

L’auteur propose d’interroger deux aspects de la temporalité psychique à l’œuvre dans les pratiques éducatives. D’une part, la modalité du temps qui s’articule au registre de la Loi et participe à son expression (temps du Surmoi), d’autre part ce qui tient à la dynamique des désirs, à l’interfantasmatisation, à l’assise imaginaire de l’éducation et qui participe au fondement du sens même de tout projet (de vie, ou professionnel) pour les adolescents.

The integration of learning cognitive agents in the research agenda is an important step in the evolution of economics. However, relying on a retrospective analysis of the treatment of decision making in economics, this article argues that the cognitive programme aims to justify rational behaviour in an equilibrium framework rather than to integration an interpretative conception of agents' behaviour. As a consequence, the level of generality of analytical results remains limited and economists miss the opportunity to establish a discussion with (...) other social sciences. In particular, it fails to analyse a class of situations related to the problem of knowledge creation and the subsequent learning paradox. Building on recent advances in heterodox cognitive science, we suggest a behavioural approach that discriminates different learning situations. If applied, this approach would permit a better understanding of human behaviour and a richer analysis of coordination mechanisms in unfamiliar environment with no loss of rigour. (shrink)

Elie Halévy's later works have made him one of the most renowned French liberal thinkers of the twentieth century. I want to argue, however, that there exists another facet of the man, more republican than liberal, to be found in his pre-Great War papers. Halévy reveals himself as a man with reformist tendencies, concerned with the concrete aspects of freedom, both for individuals and peoples, and therefore holding more qualified views on the project of a political and social control of (...) the economy. My analysis focuses on Halévy's unpublished first series of lectures on the history of European Socialism, delivered in 1902 at the Ecole Libre des Sciences Politiques, in which the major features of this early Halévy can be best identified.

Dijkerman & de Haan (D&dH) study perception and action as two independent processes. However, in all daily activities the processes are completely intertwined, so it is difficult to separate one from the other. Humans perceive in order to move and also move in order to perceive. Understanding first how perception and action are coordinated, leads us then to determine how each component works independently.

"À une époque où la cinéphilie n'est plus qu'une paraphilie parmi les autres, aussi estimable et inoffensive qu'une autre, en un temps où la sédition installée tient lieu d'horizon, il y a sans doute quelque naïveté à prétendre se démarquer de la modernité en se réclamant d'une "cinéphilie dissidente". Pourtant sous l'insurrection permanente, des règles intangibles et des principes incontestables demeurent, qu'il est nécessaire d'enfreindre. Derrière l'équivalence des opinions et la relativité des goûts, de nouvelles hiérarchies se sont bâties, qu'il (...) importe de renverser. Cette attitude d'opposition serait à son tour éminemment moderne s'il ne s'agissait par ce refus, de promouvoir une autre attention aux faits, une autre rapport à autrui, que ceux que notre époque favorise. Lorsque nous aurons admis que le cinéma moderne nous a dépossédés de nos mots, en y substituant les siens, qui décrivent de mille feux ce qui s'éteint, lorsque nous aurons saisi que nous ne parlons qu'en son non, ne répétons que ses désordres, ne prions que ses décalogues rafraîchis, nous aurons alors tout le temps de regretter notre silence. Dans ces conditions, c'est bien par l'écriture qu'il s'agit d'instaurer une relation cette fois intempestive avec l'image cinématographique. À travers le prisme de plus de deux cents films, mêlant la critique cinématographique et le journal intime, l'analyse et l'aphorisme, cet essai se propose de résister à la cinéphilie officielle, absolument indolore, qui n'est plus qu'une technique parmi d'autres d'embrigadement. Sous la forme d'abécédaire, de A comme Artifices à Z comme Zombies, en passant par l'Enfance, la Honte, le Messie, les Nazis ou la Pornocratie, il n'est autre qu'une tentat. (shrink)

Every function over the natural numbers has an infinite subdomain on which the function is non-decreasing. Motivated by a question of Dzhafarov and Schweber, we study the reverse mathematics of variants of this statement. It turns out that this statement restricted to computably bounded functions is computationally weak and does not imply the existence of the halting set. On the other hand, we prove that it is not a consequence of Ramsey’s theorem for pairs. This statement can therefore be seen (...) as an arguably natural principle between the arithmetic comprehension axiom and stable Ramsey’s theorem for pairs. (shrink)

Jean Klein a été l'un des principaux passeurs de la non-dualité indienne (advaita) et du yoga en France. Il a exercé et continue d'exercer une influence considérable dans les cercles de chercheurs spirituels. Dans cet ouvrage, Ludovic Fontaine a choisi d'interviewer trois enseignants, trois des principaux élèves de Jean Klein, qui s'inscrivent de manière originale et ouverte dans la perspective de leur maître. Eric Baret, Francis Lucille, et Jean-Marc Mantel présentent ici leur parcours spirituel, leur perspective propre sur la (...) non-dualité, l'éveil, la nature de la réalité. Ludovic les interroge également sur leur méthode d'enseignement : comment transmettent-ils l'éveil? Quel est leur rapport aux traditions (advaita vedanta, tantrisme cachemirien, yoga)? Quelles pratiques préconisent-ils? Qu'est-ce que ces pratiques non-duelles peuvent changer dans notre vie? Chacun pourra trouver dans ces magnifiques entretiens des renseignements précieux sur le chemin vers la liberté et la joie."--Page 4 of cover. (shrink)

scholarly interest in johannes clauberg's philosophy increased significantly in the twentieth century, and the renaissance continued in the first decade of the twenty-first century. This is mainly due to the 1968 reprint of his Opera Omnia Philosophica,1 and to such events as the colloquium entirely devoted to Clauberg held in Groningen on 15 and 16 December 1995. The ground-breaking papers presented on that occasion, collected by Theo Verbeek in Johannes Clauberg and Cartesian Philosophy in the Seventeenth Century,2 offer a comprehensive (...) overview of Clauberg's thought and supersede the outdated works by Müller,3 Brosch,4 and Weier,5 who tended to interpret Clauberg's philosophy as an...

The horse was essential to past human societies but became a recreational animal during the twentieth century as the world became increasingly mechanized. As the author reviews here, recent studies of ancient genomes have revisited the understanding of horse domestication, from the very early stages to the most modern developments. They have uncovered several extinct lineages roaming the far ends of Eurasia some 4000 years ago. They have shown that the domestic horse has been significantly reshaped during the last millennium (...) and experienced a sharp decline in genetic diversity within the last two centuries. At a time when no truly wild horses exist any longer, this calls for enhanced conservation in all endangered populations. These include the Przewalski's horse native to Mongolia, and the many local breeds side‐lined by the modern agenda, but yet representing the living heritage of over five millennia of horse breeding.

A better understanding of media effects on immigration attitudes is crucial for policy development and innovation. While many studies have focused on immigration discourses or the salience of this issue in print media and broadcast TV, few have looked at how different “media diets” influence immigration attitudes. Using two-wave panel data composed of 14,480 observations (7,240 individuals) from nine EU countries, this article specifically analyses the role of online and social media news consumption as well as media diet diversity on (...) Europeans’ perceptions of the economic and cultural impact of immigration. The results show that relying primarily on online or social media (compared to print newspapers) to get news, consuming news less frequently, or having a less diverse media diet all significantly and negatively influence people’s perceptions of the impact of immigration. Results and implications are discussed in light of today’s changing media landscape and news consumption habits. (shrink)

La présentation de ce dossier l’inscrit dans les recherches récentes sur l’origine moderne du mot ontologia, sur son historiographie, sur les apories de la métaphysique scolastique dont l’ontologie hérite, sur son contexte initialement calviniste, sur les moments principaux de son développement et sur la thèse fondamentale qui, réduisant l’étant à un pur concept, l’identifie au pensable – jusqu’à la fascination ambivalente de Kant, qui, avant que la Critique de la raison pure n’entende substituer au nom orgueilleux d’ontologie le nom modeste (...) d’une analytique de l’entendement pur, avait envisagé, dans les années 1770, son remplacement par une anthropologie transcendantale.

In 1842, the Parisian editor Louis-Antoine Pagnerre published the Dictionnaire politique. This large volume was the manifesto of the French Republicans in opposition to the conservative governments of King Louis-Philippe under the July Monarchy. One of the most original aspects of the Dictionnaire resides in the attempt to link the doctrine of republicanism to political economy. It is the purpose of this paper to analyse the republican political economy presented in Pagnerre's dictionary. First, we detail the historical context in which (...) it appeared, stressing on Pagnerre's biography and on the composition of the group of young republicans who wrote the main economic entries of the book. Second, we focus on the economic ideas about the political regulation of industrial phenomena and the solutions these Republicans imagined to solve the social question. Third, we conclude by attempting to summarize the main characteristics of this republican political economy and to appreciate its originality. (shrink)

Here, we propose that bidirectionality in implicit motor coordination between humanoid robots and humans could enhance the social competence of human–robot interactions. We first detail some questions pertaining to human–robot interactions, introducing the Uncanny Valley hypothesis. After introducing a framework pertinent for the understanding of natural social interactions, motor resonance, we examine two behaviors derived from this framework: motor coordination, investigated in and informative about human–human interaction, and motor interference, which demonstrate the relevance of the motor resonance framework to describe (...) human perception of humanoid robots. These two lines of investigation are then put together to “close the loop” by proposing to implement a key feature of motor coordination, bidirectionality, in robots’ behavior. Finally, we discuss the feasibility of implementing motor coordination between humanoid robots and humans, and the consequences of this implementation in enhancing the social competence of robots interacting with humans. Keywords: interpersonal interaction, motor resonance, motor coordination, motor interference, social robotics, anthropomorphism. (shrink)
