A value space is a topological algebra equipped with a non-empty family of continuous quantifiers . We will describe first-order logic on the basis of . Operations of are used as connectives and its relations are used to define statements. We prove under some normality conditions on the value space that any theory in the new setting can be represented by a classical first-order theory.

In this book Bruno Latour brings together these different approaches to provide a lively and challenging analysis of science, demonstrating how social context..

Bruno Latour was once asked : "Do you believe in reality?" This text is an attempt to answer this question.

Bruno Latour is best known for his work in the cultural study of science. In this pamphlet he turns his attention to another worthy pursuit: the project of peace. As one might expect, Latour gives us a radically different picture of this project than Kant or the philosophes, asserting that the West has been in a constant state of war both with other cultures and its own—although unwittingly so. Read through the lens of his trademark take on "the modern," (...) his arguments are original, thoughtful, and, as usual, provocative. (shrink)

In this paper, my aim is to reconstruct, through the material presented in the handschrifter Nachlaß, Kant`s criticism to Hutcheson and to the doctrine of moral feeling in the 1770s in the so called silent decade. As we can note, this criticism generally is addressed to the fact that the doctrine of moral feeling is lacking an objective ground on which can be established a categorical conception of ethics. Moreover, I argue that in this context Kant already demonstrates, from his (...) critical position in the Reflexionen and Vorlesungen, the general lines of his mature conception on moral feeling as something strictly linked to our awareness of the law.

Given recent advances in technology, connectivity, and the popularity of social media platforms, recent literature has devoted great attention to problematic Facebook use. However, exploring the potential predictors of problematic social media use beyond Facebook use has become paramount given the increasing popularity of multiple alternative platforms. In this study, a sample of 584 social media users was recruited to complete an online survey assessing sociodemographic characteristics, patterns, and preferences of social media use, problematic social media use, social media use (...) motives, psychological well-being, self-esteem, and positive and negative affect. Results indicated that 6.68% of all respondents could be potentially classed as problematic users. Moreover, further analysis indicated that intrapersonal motive, negative affect, daily social media use, surveillance motive, and positive affect each predicted PSMU. These variables accounted for about 37% of the total variance in PSMU, with intrapersonal motive driving the greatest predictive contribution, over and above the effects of patterns of social media use and sociodemographic variables. These findings contribute to the increasing literature on PSMU. The results of this study are discussed in light of the existing literature on PSMU. (shrink)

Background: Differential learning is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed, Web of (...) Science, and Google Scholar were searched until February 3, 2020. To be included, studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method, studies had to describe the effects on one or more measures of performance in a skill or movement task, and the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase as well as for the retention phase was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found. (shrink)

While it is generally accepted that texts concerning navigation written by the Portuguese mathematician and cosmographer Pedro Nunes (1502–1578) were influential in erudite circles of Europe, less is known about the real impact and diffusion of his work among the less educated, such as professionals associated with sea voyages. Did Nunes' theoretical contributions reach the relevant artisans and practitioners? If so, how did this come about?This paper uses the case of Pedro Nunes to investigate how complex theoretical ideas were transmitted (...) to artisans in early modern Europe. It begins by examining the ways in which Nunes managed to interface with practitioners while working as a cosmographer. Second, it focuses on how his ideas, techniques, and results were used and transmitted by other agents, such as fellow cosmographers, navigation teachers, or mathematical practitioners. This paper concentrates on the transmission of such knowledge through vernacular texts – mainly navigation manuals and class notes – produced in the Iberian Peninsula and England in the 16th and 17th centuries. It shows how these agents facilitated the convergence between two distinct intellectual worlds – those of scholars and those of artisans – by rendering highly mathematical subjects more accessible to practitioners.

We study two notions of definability for classes of relational structures based on modal extensions of Łukasiewicz finitely-valued logics. The main results of the paper are the equivalent of the Goldblatt-Thomason theorem for these notions of definability.

Les sciences sociales, depuis le structuralisme, se sont développées en France sur fond d'ignorance ou de rejet déclaré de la philosophie de type phénoménologique. De son côté, celle-ci a pris un tour qui l'a de plus en plus éloignée des sciences positives en général et des sciences humaines en particulier. Pourtant, lorsque la sociologie, comme c'est le cas aujourd'hui, cherche à cerner la figure de l'acteur social et à interroger les conditions de sa subjectivation - de sa constitution comme sujet (...) social - une confrontation avec cette philosophie pourrait s'avérer fructueuse. Et pour une phénoménologie qui n'a que trop tendance à se confondre avec la forme actuelle de la métaphysique, un retour sur l'inscription sociale de ce qu'elle décrit, et une mise à l'épreuve de la critique sociologique, pourrait en retour être salutaire. C'est dans cet esprit que les auteurs de ce collectif ont tenté de construire des liens, dans une réflexion croisée sur le caractère immédiatement social de la subjectivité et sur la nécessité de penser les conditions d'appropriation de l'espace social par des sujets.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa (Epistles of the Brethren of Purity). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in mathematics, logic, (...) natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. The Rasa'il constitutes a paradigmatic legacy in the canonization of philosophy and the sciences in mediaeval Islamic civilization, as well as having shown a permeating influence in Western culture. This is the fifth volume in a series presenting the very first critical edition of the Rasa'il in its original Arabic, complete with the first fully annotated English translation. Epistle 52: On Magic is the last in the corpus, and presents the short version of the 'Epistle on Magic, Incantations, and the Evil Eye'. Within its pages the authors of the epistle argue for the legitimacy of magic and the other occult sciences, and seek confirmation of their views in authorities as diverse as Plato, the Qur'ân, the Torah, the astrologer Abû Ma'shâr, and the mysterious sect of pagan star-worshippers known as the Sabians of Harrân. As in all other volumes of the series, this volume provides the first critical edition of the Arabic text, together with an English translation and a substantial range of notes. An extensive introduction highlights the unique relevance of this treatise within the framework of the Brethren's encyclopaedia itself, and to the history of science in general. (shrink)

Giordano Bruno’s Cabala del cavallo pegaseo _ _grew out of the great Italian philosopher’s experiences lecturing and debating at Oxford in early 1584. Having received a cold reception there because of his viewpoints, Bruno went on in the Cabala to attack the narrow-mindedness of the university--and by extension, all universities that resisted his advocacy of intellectual freethinking. _The Cabala of Pegasus _consists_ _of vernacular dialogues that turn on the identification of the noble Pegasus and the humble ass. In (...) the interplay of these ideas, Bruno explores the nature of poetry, divine authority, secular learning, and Pythagorean metempsychosis, which had great influence on James Joyce and many other writers and artists from the Renaissance to the modern period. This book, the first English translation of _The Cabala of Pegasus, _contains both the English and Italian versions as well as helpful annotations. It will have particular appeal to all Renaissance scholars and those interested in the Renaissance cabalistic underpinnings of modern literature. (shrink)

Several countries maintain universal health coverage, which implies responsibility to organize delivery formats of healthcare services and products for citizens. In Brazil, the health system has a principle of universal access for more than 30 years, but many deficiencies remain and the country observes a day practice for those seeking judicial decisions to determine provision of healthcare.

We first discuss some technical questions which arise in connection with the construction of undecidable propositions in analysis, in particular in connection with the notion of the normal form of a function representing a predicate. Then it is stressed that while a function f(x) may be computable in the sense of recursive function theory, it may nevertheless have undecidable properties in the realm of Fourier analysis. This has an implication for a conjecture of Penrose's which states that classical physics is (...) computable. (shrink)

Résumé Partant du principe que les raisons de la politisation (ou non) de la référence théorique « Leo Strauss » ne peuvent être élucidées qu’en considérant ensemble les écrits du philosophe et les processus de réception dont ils font l’objet, cette contribution propose quelques éléments de biographie intellectuelle, distinguant six « séquences » puis elle met en lumière l’aspect « polyphonique » de l’oeuvre straussienne, semblant autoriser les lectures les plus contradictoires. Suit une exposition de deux paradigmes opposés de réception (...) : la réception étatsunienne, rythmée par les polémiques depuis les années 1980, la réception française, assez consensuelle. À la fin du texte, nous tentons d’expliquer comment Strauss a pu devenir une figure canonique en France dans le contexte du « retour de la philosophie politique » des années 1980-1990. (shrink)

O ensaio analisa o papel da filosofia na formação do docente do Ensino Médio; parte de Adorno que, enquanto avaliador da prova geral de filosofia nos exames de habilitação para o magistério em ciências nas IES alemãs, destacava o papel formativo da filosofia e como a ênfase no ensino profissional ofuscava a formação intelectual. Após resgatar o potencial histórico da Bildung, o ensaio se volta para os dias de hoje e tenta iluminar a atuação da filosofia na formação docente do (...) ensino médio. Dois grupos de problemas são levantados: o domínio de organizações privadas, cursos noturnos e EaD na formação; a submissão dessas organizações ao mercado. Consequência: o privilégio das competências e o desprestígio da formação. Ao final, o ensaio tenta resgatar o potencial da filosofia na formação desse profissional. (shrink)

This article tackles the political implications of Reinhart Koselleck’s first work, Kritik und Krise, re-questioning its relationship to the ‘Enlightenment’ and the ‘Counter-Enlightenment’. Rather than establishing the semantic contents of this pair of antonymic concepts in an abstract way, I believe that we must study the concrete uses to which they are put, that is, the discursive strategies of the actors themselves showing, in each case, the specific adversaries against whom they are mobilized and the specific ends to which they (...) are used. The goal of the present essay is to understand whether the early Koselleck belonged to the tradition of the Enlightenment or the Counter-Enlightenment in the specific context of post-War West Germany intellectual debates. By locating Kritik und Krise in the controversies relating to the political identity of the new German Federal Republic, I show that he was not, in the 1950s, a representative of Cold War Liberalism or anti-totalitarianism but, rather, oscillated between different conservative positions (‘Traditional’ conservatism and ‘Conservative Revolution’) that were typical of the post-War period and, in large measure, hostile to the Enlightenment legacy.

Logical omniscience states that the knowledge set of ordinary rational agents is closed for its logical consequences. Although epistemic logicians in general judge this principle unrealistic, there is no consensus on how it should be restrained. The challenge is conceptual: we must find adequate criteria for separating obvious logical consequences (consequences for which epistemic closure certainly holds) from non-obvious ones. Non-classical game-theoretic semantics has been employed in this discussion with relative success. On the one hand, with urn semantics [15], an (...) expressive fragment of classical game semantics that weakens the dependence relations between quantifiers occurring in a formula, we can formalize, for a broad array of examples, epistemic scenarios in which an individual ignores the validity of some first-order sentence. On the other hand, urn semantics offers a disproportionate restriction of logical omniscience. Therefore, an improvement of this system is needed to obtain a better solution of the problem. In this paper, I argue that our linguistic competence in using quantifiers requires a sort of basic hypothetical logical knowledge that can be formulated as follows: when inquiring after the truth-value of ∀xφ, an individual might be unaware of all substitutional instances this sentence accepts, but at least she must know that, if an element a is given, then ∀xφ holds only if φ(x/a) is true. This thesis accepts game-theoretic formalization in terms of a refinement of urn semantics. I maintain that the system so obtained (US+) affords an improved solution of the logical omniscience problem. To do this, I characterize first-order theoremhood in US+. As a consequence of this result, we will see that the ideal reasoner depicted by US+ only knows the validity of first-order formulas whose Herbrand witnesses can be trivially found, a fact that provides strong evidence that our refinement of urn semantics captures a relevant sense of logical obviousness.

LaFollette proposed that the best way to protect children from abuse and neglect caused by their parents would be to implement parental licenses to prospective parents. In this paper, I re-evaluate his proposal by looking at various facts and data related to child abuse and neglect. It will be suggested that (a) parenting as a profession does not satisfy the third of LaFollette’s criteria for the introduction of licenses, which is “The benefits of the licensing program outweigh any theoretical reasons (...) against it” (LaFollette 2010, 328), (b) it would subject too many people to unnecessary tests and (c) parenting cannot be compared to other professions licenses are usually issued for.

La mission du juge est de trancher les litiges. Or, avant de d’appliquer une règle juridique, il est nécessaire de connaître précisément les faits de la cause. « Da mihi factum, dabo tibi jus ».

On note toutefois une évolution considérable qui tend à demander à l’expert, non plus (...) seulement d’observer une situation passée ou présente mais de prévenir l’avenir. (shrink)
