A presente Comunicação pretende analisar comparativamente alguns aspectos da definição de modernidade e pós-modernidade e sua aplicabilidade na análise do contexto religioso brasileiro. Partindo de autores como Giddens e Bauman, desenvolvemos a contextualização de suas teorias para uma realidade eminentemente européia. Depois, com autores como Canclini, Mariano e Prandi, dentre outros, que analisaram o contexto latino americano e, principalmente, brasileiro, procurou-se delinear o erro em se considerar que os conceitos de modernidade e pós-modernidade cabem à análise do cenário religioso brasileiro (...) irrestritamente, como se este cenário fosse equivalente ao europeu, lugar no qual esses conceitos surgiram e foram delineados. Palavras-chave : Modernidade; Pós-modernidade, Cenário Religioso Brasileiro, Cenário Religioso Europeu. (shrink)

Desde el campo de las Neurociencias, las emociones implican cambios fisiológicos, comportamentales y cognitivos. En dichas respuestas interviene el sistema nervioso. El abuso infantil, bullying y adicciones en niños, niñas y adolescentes impactan negativamente sobre su sistema neuroendócrino e inmunitario. La vulnerabilidad fisiológica que esto implica produce alteraciones en la funciones cognitivas que impactan desfavorablemente sobre el desarrollo escolar.

This essay reevaluates the work of Herbert Croly, a central figure in American progressivism. Croly contests the thesis that the liberal tradition in the United States is inhospitable to anticapitalist alternatives, drawing from the American past a history of resistance to capitalist wage relations that is fundamentally liberal. This historical reconstruction guides his departure from progressivism. Croly reclaims an idea Progressives allowed to lapse -- that working for wages is a lesser form of liberty. Increasingly sceptical of social welfare (...) legislation to remedy social ills, he argues that America's liberal promise can be redeemed only by syndicalist reforms involving workplace democracy.

En este artículo se estudia la representación de la infancia en la poesía de Delia Domínguez, la que se expresa como una estética de la orfandad y el huachismo que intentan restituir un estado primigenio, embrionario, mediante un constante mirar para atrás con ojos de niña, en el contexto de una comunidad poetizada que da lugar al encuentro regresivo e imposible de la madre con la hija. En esta búsqueda, la infancia cumple un rol reunificador y reparador. In this article, (...) the representation of childhood in Delia Domínguez's poetry is analyzed. This is expressed as an aesthetics of orfhanhood and bastardy that tries to return to an original, embryonic condition, by means of a constant looking back through a girl's eyes, in the context of a poeticized community that gives way to the regressive and impossible meeting of a mother and her daughter. In this search, childhood fulfills a reunifying and repairing role. (shrink)

Given two (positive) equivalence relations ∼ 1 , ∼ 2 on the set ω of natural numbers, we say that ∼ 1 is m-reducible to ∼ 2 if there exists a total recursive function h such that for every x, y ∈ ω, we have $x \sim_1 y \operatorname{iff} hx \sim_2 hy$ . We prove that the equivalence relation induced in ω by a positive precomplete numeration is complete with respect to this reducibility (and, moreover, a "uniformity property" holds). This (...) result allows us to state a classification theorem for positive equivalence relations (Theorem 2). We show that there exist nonisomorphic positive equivalence relations which are complete with respect to the above reducibility; in particular, we discuss the provable equivalence of a strong enough theory: this relation is complete with respect to reducibility but it does not correspond to a precomplete numeration. From this fact we deduce that an equivalence relation on ω can be strongly represented by a formula (see Definition 8) iff it is positive. At last, we interpret the situation from a topological point of view. Among other things, we generalize a result of Visser by showing that the topological space corresponding to a partition in e.i. sets is irreducible and we prove that the set of equivalence classes of true sentences is dense in the Lindenbaum algebra of the theory.

In the present work we try to return to the problem of Merleau-Ponty’s historic and political evaluation of action in the light of his accounts in Humanism and Terror and their updating in the last years by commentators such as Alexandre Hubeny, Leonardo Eiff and Jérôme Melançon. We will present some arguments against two very close related theses by Merleau-Ponty: that of the “objective” evaluation of action, which holds that the subjects behavior can be described as constituing a “betrayal” or (...) a “crime” independently of any attribution of intentions to the agents and the thesis of the “objective” responsibility of the agent, that is, the tenet that affirms that the historic and political subjects can be “responsible” or “guilty” for an outcome of their actions, that they cannot have foreseen or can be the exact opposite for what they intended.

We generalize a well-knownSmullyan's result, by showing that any two sets of the kindC a = {x/ xa} andC b = {x/ xb} are effectively inseparable (if I b). Then we investigate logical and recursive consequences of this fact (see Introduction).

The advent of Generative AI, particularly through Large Language Models (LLMs) like ChatGPT and its successors, marks a paradigm shift in the AI landscape. Advanced LLMs exhibit multimodality, handling diverse data formats, thereby broadening their application scope. However, the complexity and emergent autonomy of these models introduce challenges in predictability and legal compliance. This paper analyses the legal and regulatory implications of Generative AI and LLMs in the European Union context, focusing on liability, privacy, intellectual property, and cybersecurity. It examines (...) the adequacy of the existing and proposed EU legislation, including the Artificial Intelligence Act (AIA), in addressing the challenges posed by Generative AI in general and LLMs in particular. The paper identifies potential gaps and shortcomings in the EU legislative framework and proposes recommendations to ensure the safe and compliant deployment of generative models. (shrink)

The article argues that AI can enhance the measurement and implementation of democratic processes within political parties, known as Intra-Party Democracy (IPD). It identifies the limitations of traditional methods for measuring IPD, which often rely on formal parameters, self-reported data, and tools like surveys. Such limitations lead to the collection of partial data, rare updates, and significant demands on resources. To address these issues, the article suggests that specific data management and Machine Learning (ML) techniques, such as natural language processing (...) and sentiment analysis, can improve the measurement (ML about) and practice (ML for) of IPD. The article concludes by considering some of the principal risks of ML for IPD, including concerns over data privacy, the potential for manipulation, and the dangers of overreliance on technology.

Regulation is nothing without enforcement. This particularly holds for the dynamic field of emerging technologies. Hence, this article has two ambitions. First, it explains how the EU´s new Artificial Intelligence Act (AIA) will be implemented and enforced by various institutional bodies, thus clarifying the governance framework of the AIA. Second, it proposes a normative model of governance, providing recommendations to ensure uniform and coordinated execution of the AIA and the fulfilment of the legislation. Taken together, the article explores how the (...) AIA may be implemented by national and EU institutional bodies, encompassing longstanding bodies, such as the European Commission, and those newly established under the AIA, such as the AI Office. It investigates their roles across supranational and national levels, emphasizing how EU regulations influence institutional structures and operations. These regulations may not only directly dictate the structural design of institutions but also indirectly request administrative capacities needed to enforce the AIA. (shrink)

One might suppose that Everettian quantum mechanics (EQM) is inhospitable to metaphysial indeterminacy (MI), given that, as A. Wilson (2020) puts it, "the central idea of EQM is to replace indeterminacy with multiplicity" (77). But as Wilson goes on to suggest, the popular decoherence-based understanding of EQM (henceforth: DEQM) appears to admit of indeterminacy in both world number and world nature, where the latter indeterminacy---our focus here---is plausibly metaphysical. After a brief presentation of DEQM (S1), we bolster the case for (...) there being MI in world nature in DEQM (S2). The remainder of the paper is devoted to a comparative assessment of the two main approaches to MI for purposes of accommodating this MI---namely, a metaphysical supervaluationist approach (as per Barnes and Williams 2011) and a determinable-based approach (as per Wilson 2013 and Calosi and Wilson 2018 and 2021). We briefly describe each approach (S3), then offer arguments in favour of a determinable-based approach to world nature MI in DEQM (S4). (shrink)

Are submergence and submergent properties metaphysically possible? This is a substantive question that has been either utterly neglected or quickly answered in the negative. This neglect is not only significant in itself; the possibility of submergence plays a crucial role in hotly debated topics in metaphysics, for example, the debate over Monism and Pluralism. This paper is intended to prompt a discussion about metaphysical submergence. In particular I will provide examples of submergent properties, argue that these are metaphysically possible and (...) finally propose a pluralist argument from submergence. (shrink)

By an unfounded chain for a function f:X→X we mean a sequence nω of elements of X s.t. fxn+1=xn for every n. Unfounded chains can be regarded as a generalization of fixed points, but on the other hand are linked with concepts concerning non-well-founded situations, as ungrounded sentences and the hypergame. In this paper, among other things, we prove a lemma in general topology, we exhibit an extensional recursive function from the set of sentences of PA into itself without an (...) unfounded chain, and we prove that every term in a Magari algebra has an unfounded chain.

The paper studies the relation between systems of modal logic and systems of consequential implication, a non-material form of implication satisfying "Aristotle's Thesis" (p does not imply not p) and "Weak Boethius' Thesis" (if p implies q, then p does not imply not q). Definitions are given of consequential implication in terms of modal operators and of modal operators in terms of consequential implication. The modal equivalent of "Strong Boethius' Thesis" (that p implies q implies that p does not imply (...) not q) is identified. (shrink)

Who has the power to institutionalize culture? How is it that cultural forms become legitimated and appropriated by certain groups? And what are the organizational forms that guarantee the continuity of the interlocks among classifications, etiquette, and resources in the long run? This article explores these questions by observing the struggle over the institutionalization of opera as high culture during the late nineteenth century and early twentieth century in Buenos Aires, a region of the world understudied by cultural sociologists. It (...) contends that to answer these questions we need to observe the contested dynamics though which the process of institutionalization happens. It also shows how this contestation affects, in the long-term, the processes of evaluation and legitimation of the classification upheld, and the consequences it has in terms of audience stratification. In the Discussion section, I present a novel framework for the study of pathways to high culture institutionalization that highlights how the role of the state and competing stakeholders can introduce variable relationships among the elites, the arts, and social closure.

Extended simple regions have been the focus of recent developments in philosophical logic, metaphysics, and philosophy of physics. However, only a handful of works provides a rigorous characterization of an extended simple region. In particular, a recent paper in this journal defends a definition based on an extrinsic notion of least distance. Call it the Least Distance proposal. This paper provides the first assessment of it. It argues that Least Distance faces difficulties and drawbacks. The paper then goes on to (...) suggest a different proposal, the Diameter proposal that is able to handle such drawbacks and difficulties. (shrink)

We present a procedure which allows us to recover classical and nonclassical logical structures as concrete logics associated with physical theories expressed by means of classical languages. This procedure consists in choosing, for a given theory ${{\mathcal{T}}}$ and classical language ${{\fancyscript{L}}}$ expressing ${{\mathcal{T}}, }$ an observative sublanguage L of ${{\fancyscript{L}}}$ with a notion of truth as correspondence, introducing in L a derived and theory-dependent notion of C-truth (true with certainty), defining a physical preorder $\prec$ induced by C-truth, and finally selecting (...) a set of sentences ϕ V that are verifiable (or testable) according to ${{\mathcal{T}}, }$ on which a weak complementation ⊥ is induced by ${{\mathcal{T}}. }$ The triple $(\phi_{V},\prec,^{\perp})$ is then the desired concrete logic. By applying this procedure we recover a classical logic and a standard quantum logic as concrete logics associated with classical and quantum mechanics, respectively. The latter result is obtained in a purely formal way, but it can be provided with a physical meaning by adopting a recent interpretation of quantum mechanics that reinterprets quantum probabilities as conditional on detection rather than absolute. Hence quantum logic can be considered as a mathematical structure formalizing the properties of the notion of verification in quantum physics. This conclusion supports the general idea that some nonclassical logics can coexist without conflicting with classical logic (global pluralism) because they formalize metalinguistic notions that do not coincide with the notion of truth as correspondence but are not alternative to it either.

By drawing on Husserl’s manuscripts on Phantasy, Image Consciousness and Memory, this paper aims to shed light on some of the primary concepts defining his notion of image—such as “belief,” “presentification” and perzeptive Phantasie—and endeavours to show how such concepts could be profitably developed for the sake of a phenomenological description of film image. More in particular, these analyses aim to give a phenomenological account of the distinction between positing film images, presupposing a claim to reality—for example the ones we (...) experience in a documentary attitude—and quasi-positing film images involved in artistic creation. The latter, despite their photographic relation to reality, are capable of giving rise to filmic “image-worlds” having intersubjective existence. (shrink)

It is natural to ask under what conditions negating a conditional is equivalent to negating its consequent. Given a bivalent background logic, this is equivalent to asking about the conjunction of Conditional Excluded Middle (CEM, opposite conditionals are not both false) and Weak Boethius' Thesis (WBT, opposite conditionals are not both true). In the system CI.0 of consequential implication, which is intertranslatable with the modal logic KT, WBT is a theorem, so it is natural to ask which instances of CEM (...) are derivable. We also investigate the systems CIw and CI of consequential implication, corresponding to the modal logics K and KD respectively, with occasional remarks about stronger systems. While unrestricted CEM produces modal collapse in all these systems, CEM restricted to contingent formulas yields the Alt2 axiom (semantically, each world can see at most two worlds), which corresponds to the symmetry of consequential implication. It is proved that in all the main systems considered, a given instance of CEM is derivable if and only if the result of replacing consequential implication by the material biconditional in one or other of its disjuncts is provable. Several related results are also proved. The methods of the paper are those of propositional modal logic as applied to a special sort of conditional. (shrink)

This article examines how therapists and patients start building and managing relationships and pursue institutional goals at the same time. Based on a corpus of 6 audio-recorded therapies (client-centered therapy and psychodynamic therapy), I investigate first encounters between therapists and patients as the starting points of any therapeutical process and the place where a relationship between the interactants is established for the first time. Following a microlinguistic qualitative approach and applying methods from conversation analysis and discourse analysis, I show how (...) therapists, on the one hand, try to align with patients to build a positive working alliance and, on the other hand, work to fulfill specific interactive tasks of therapeutic discourse which demand disaligning with the patients’ communicative activity and their interactive expectations. Specific interactive “jobs” that need to be fulfilled in psychotherapy are identified, namely the performance of institutional roles by the interactants, the establishment of an interaction structure and the pursuit of helpful change in the patient. I show at which places in the interaction therapists (dis-)align with the patients’ projected communicative activity and how aligning and disaligning are related to the interactive process and the establishment and performance of these interactive jobs. The analysis shows that, at the beginning of therapy, alignment and disalignment are both important processes for the following reasons: Aligning with the patient contributes to a positive relationship, which has been shown to be vital for successful psychotherapy, while disaligning introduces the patient to the specific discursive mechanisms that characterize therapeutic discourse and constitute the basis for its effectiveness. Overall, the paper argues that reducing therapy to a dichotomy between relationship and “technique” seems overly simplistic, as both aspects need to be handled and managed at the same time. (shrink)

In comparison to other art forms, dance remains underrepresented in the medical humanities, especially within the academic medical setting. Several factors, including perceived lack of applicability to patient care, contribute to this pattern. This paper contends that, to the contrary, learners across the medical education spectrum stand to gain much from engaging with the movement arts, including improvement of clinically-relevant skills such as physical self-awareness, observation, communication, and mindfulness. This paper makes the case for the nascent subdiscipline of Movement and (...) Medicine, developed by the authors and piloted for inclusion in medical humanities curricula within a medical education context. Movement and Medicine employs a dance-inspired pedagogy to a) promote awareness of personal movement and embodiment tendencies and b) harness that awareness to gain more profound, sensory insight into the embodied experiences of others—experiences of health, illness, or otherwise. This work outlines the research, rationale, and philosophy behind Movement and Medicine; concretely defines the subdiscipline and situates it within the medical humanities landscape; proposes practical approaches to engaging with and applying this material; and describes a Movement and Medicine course developed for one American medical school.

The aim of the paper is to outline a treatment of cotenability inspired by a perspective which had strong roots in ancient logic since Chrysippus and was partially recovered in the XX Century by E. Nelson and the exponents of so-called connexive logic. Consequential implication is a modal reinterpretation of connexive implication which permits a simple reconstruction of Aristotle's square of conditionals, in which proper place is given not only to ordinary cotenability between A and B, represented by ¬, but (...) to its “secondary” variant ¬ . After showing that logics of strict implication, of Stalnaker-Lewis conditionals and of relevant implication do not satisfy the intuitive properties required for cotenability , it is proved that such conditions are satisfied by consequential cotenability and by its secondary variant . The notions of strong cotenability and of bilateral cotenability are then introduced: the latter stands to standard cotenabilty as contingency stands to possibility, and in Section 9 it is shown to be a useful tool in the reconstruction of Boethius' theory of adjuncta.

In the first part of the paper it is proved that there exists a one–one mapping between a minimal contingential logic extended with a suitable axiom for a propositional constant τ, named KΔτw, and a logic of necessity ${K\square \tau{w}}$ whose language contains ${\square}$ and τ. The form of the proposed translation aims at giving a solution to a problem which was left open in a preceding paper. It is then shown that the presence of τ in the language of (...) KΔτw allows for the definition, in terms of the non-contingency operator Δ, not only of ${\square}$ but of a second necessity operator O. It is observed that this fact opens the road to an investigation of the τ-free multimodal fragments of KΔτw. (shrink)

O principal objetivo desse artigo é interpretativo. Trata-se de historiar as tradicionais teorias descritivistas dos nomes próprios sugeridas por Frege, Russell, Wittgenstein e Searle, demonstrando que, diversamente do que é suposto, elas não constituem teorias diversas a competir entre si, mas apresentações algo diversas de um mesmo modo de ver.

The problem of determinism and freedom in the human being has always been a fruitful philosophical debate. In this discussion Spinoza is a reference in this regard, since since the publication of his works he has generated controversy around the problem. This work seeks to clarify the concept of necessity that Spinoza uses in his philosophy, in order to unravel the meaning of determinism that he builds from it. Within the analysis I show that in Spinoza’s philosophy there is no (...) clear distinction between logical necessity and metaphysical necessity. Furthermore, I argue that the concepts of contingency and possibility are de dicto and not de re issues in the author’s philosophy. That is to say, that they are not properties of the things themselves, but ways of speaking about them. Finally, I conclude that Spinoza’s thesis on determinism should be understood mainly as a necessitarianist theory, which can be compatible with a certain sense of freedom in the human being.

Grodzinsky's Tree-Pruning Hypothesis can be extended to explain agrammatic comprehension disorders. Although agrammatism is evidence for syntactic modularity, there is no evidence for its anatomical modularity or for its localization in the frontal lobe. Agrammatism results from diffuse left hemisphere damage – allowing the emergence of the limited right hemisphere linguistic competence – rather than from damage to an anatomic module in the left hemisphere.

The basis of the paper is a logic of analytical consequential implication, CI.0, which is known to be equivalent to the well-known modal system KT thanks to the definition A → B = df A ⥽ B ∧ Ξ (Α, Β), Ξ (Α, Β) being a symbol for what is called here Equimodality Property: (□A ≡ □B) ∧ (◊A ≡ ◊B). Extending CI.0 (=KT) with axioms and rules for the so-called circumstantial operator symbolized by *, one obtains a system CI.0*Eq (...) in whose language one can define an operator ↠ suitable to formalize context-dependent conditionals (so to counterfactual conditionals) via the definition (Def ↠) A ↠ B = df *A ⥽ B ∧ Ξ (Α, Β).. The central problem of the paper is to identify inside CI.0*Eq + Def ↠ a set of axioms yielding the fragment consisting of all and only theorems in which only truth-functional operators and the two operators → and ↠ occur. This system, here called CI.0, is introduced in §3. In view of the intended purpose, it is introduced a complete and tableau-decidable system KTw, which is an extension of KT with axioms for the so-called quasi-variables w(A), w(B)… Three translation functions among the three languages used in the paper are then introduced. The first, Tr, maps every wff of form *A into wffs of form w(A) ∧ A and translates theorems of CI.0*Eq into theorems of KTw. The second, t°, translates theorems of CI.0 into theorems of CI.0*Eq by applying Def↠. A third one, t, translates theorems of CI.0 into theorems of KTw. As a consequence, it follows that t°A = TrtA. In §4 it is proved that CI.0 is complete w.r.t. the class of CI.0-models of form where f is a selection function and R an access relation. It is then proved (i) that CI.0 models may be converted into KTw-models; (ii) that the truth-value of a proposition in a world of a CI.0-model is preserved in the same world of the derived KTw-model; (iii) that A is a CI.0-thesis iff its translation tA is KTw-thesis. It follows that, if A is not a CI.0-thesis, tA is not a KTw-thesis, so also that TrtA is not a CI.0*Eq-thesis. Since t°A = TrtA and t°A is a function built on Def↠, this proves that every t°-translation of a CI.0-wff that is a CI.0*Eq-theorem is a CI.0-theorem. Since the converse proposition is proved in §2, their conjunction establishes the desired result. In the final section, it is proved that CI.0 is tableau-decidable, that ↠ is not a trivial operator and that ↠ enjoys the positive and negative properties required in §1 for context-dependent conditionals. Some final remarks suggest that studying the relations between CI.0 and systems of classical conditional logic may be a promising line of investigation. (shrink)

The paper begins by focusing the basic idea that Gestalt phenomena belong not only to the realm of perception but to the realm of inference. It is shown that Gestalt effects often occur both in counterfactual and in ampliative – i.e. inductive and abductive – reasoning. The main thesis of the paper is that the common feature of such forms of non-deductive reasoning is provided by a rational selection between incompatible conclusions, where rationality lies in the choice of the alternative (...) which preserves the maximum of background information. It is also stressed a distinction between a weak and a strong notion of incompatibility. Such distinction may help in giving account of some alleged Gestalt phenomena which have been recognized in theory construction and theory change. (shrink)

In responding to a question posed by Professor Vincent Carraud regarding a passage in a letter by Etienne Pascal in which he mentions an author who speaks of the mysteries of Pythagorean numbers we have resumed our dossiers on number theory in Mersenne.

O ensaio procura investigar a ideia de educação moral defendida por Jean Piaget em sua conferência intitulada “Os procedimentos de educação moral”, proferida em Paris, no ano de 1930. Concentra-se em reconstruir o núcleo central apresentado pelo autor, ou seja, a tensão entre a dupla moralidade e a ambiguidade entre heteronomia e autonomia que constitui a moralidade infantil e que se alicerça em sentimentos de respeito opostos, de unilateralidade e de reciprocidade. Ocupa-se também em confrontar os procedimentos típicos da educação (...) tradicional com os procedimentos próprios da educação progressiva que impulsionam a posição ativa do educando para a construção dos aspectos da internalização da lei e da possibilidade das relações de cooperação e respeito pelo outro nos grupos de convivência, especialmente no período da infância. Destaca a necessária presença do adulto, como aquele que exerce o papel de mediação na relação entre ele, a criança e o mundo, principalmente do professor na educação infantil pela compreensão do domínio psicológico da infância, para pensarmos por que a criança age, como ela age e de que forma age. Por fim, conclui procurando mostrar a atualidade desta reflexão do jovem Piaget para os nossos dias, mesmo se passando quase um século, revelando a importância da releitura dos clássicos para a reflexão, compreensão e intervenção em problemáticas educacionais atuais. Sua crítica ao autoritarismo inerente à determinada concepção de educação moral serve ainda como resistência ao conservadorismo autoritário atual e, ao mesmo tempo, para reestabelecer os laços cooperativos e solidários proporcionados pela ampla tradição da educação moral autônoma, oferecendo as condições intelectuais e psicológicas necessárias para o desenvolvimento saudável e o ingresso autônomo na sociedade adulta.

We describe a particular class of pairs of quantum observables which are extremal in the convex set of all pairs of compatible quantum observables. The pairs in this class are constructed as uniformly noisy versions of two mutually unbiased bases with possibly different noise intensities affecting each basis. We show that not all pairs of MUB can be used in this construction, and we provide a criterion for determining those MUB that actually do yield extremal compatible observables. We apply our (...) criterion to all pairs of Fourier conjugate MUB, and we prove that in this case extremality is achieved if and only if the quantum system Hilbert space is odd-dimensional. Remarkably, this fact is no longer true for general non-Fourier conjugate MUB, as we show in an example. Therefore, the presence or the absence of extremality is a concrete geometric manifestation of MUB inequivalence, that already materializes by comparing sets of no more than two bases at a time.
