Annotated logics were introduced by V.S. Subrahmanian as logical foundations for computer programming. One of the difficulties of these systems from the logical point of view is that they are not structural, i.e., their consequence relations are not closed under substitutions. In this paper we give systems of annotated logics that are equivalent to those of Subrahmanian in the sense that everything provable in one type of system has a translation that is provable in the other. Moreover these new systems (...) are structural. We prove that these systems are weakly congruential, namely, they have an infinite system of congruence 1-formulas. Moreover, we prove that an annotated logic is algebraizable (i.e., it has a finite system of congruence formulas,) if and only if the lattice of annotation constants is finite. (shrink)

We introduce a family of matrices that define logics in which paraconsistency and/or paracompleteness occurs only at the level of literals, that is, formulas that are propositional letters or their iterated negations. We give a sound and complete axiomatization for the logic defined by the class of all these matrices, we give conditions for the maximality of these logics and we study in detail several relevant examples.

Within Germany, Carl Schmitt's status as a political thinker is on a par with Machiavelli and Hobbes. With the rise in neo-conservatism and authoritarian liberalism in less developed countries such as Chile and Singapore, Renato Christi believes Schmitt's theories will become of considerable importance.

The author places Grmek's editorial within the flux of the historiographical debate which, since the middle of the 1970s, has concentrated on two major crises due to the end of social science-oriented 'scientific history' and to the 'linguistic turn'. He also argues that Grmek's historiographical work of the 1980s and 1990s was to some extent an alternative to certain observed changes in historical fashion and has achieved greater intelligibility because of its commitment to a rational vision of science and historiography.

A filosofia é privativa da cultura ocidental ou é uma criação do pensamento humano em geral? As culturas africanas e afrodiaspóricas são relevantes para o entendimento da filosofia? Existe filosofia africana e/ou filosofia afro-brasileira? Em caso afirmativo, como elas podem contribuir para o entendimento das relações étnico-raciais? Como o(a) professor(a) pode incluir a filosofia africana e a afrodiaspórica no currículo de Filosofia do ensino médio? Como formar um(a) professor(a) de Filosofia capaz de fazer essa conexão? Estas são algumas das questões (...) que o professor Renato Noguera discute nesta obra, que contém roteiros de reflexão, referências a autores fundamentais e propostas curriculares práticas.

In this paper we make an algebraic study of the variety of MV*-algebras introduced by C. C. Chang as an algebraic counterpart for a logic with positive and negative truth values.We build the algebraic theory of MV*-algebras within its own limits using a concept of ideal and of prime ideal that are very naturally related to the corresponding concepts in l-groups. The main results are a subdirect representation theorem, a completeness theorem, a study of simple and semisimple algebras, and a (...) characterization of the ideal of infinitesimals as an l-group. In the last section we develop a detailed proof a the one-dimensional theorem of McNaughton, that is, the free MV*-algebra in one generator is the algebra of McNaughton functions over [−1,1]. In contrast with the rest of the paper, this last result is based on work done for MV-algebras. (shrink)

Philosophical problems about the part-whole relation have been discussed throughout the history of philosophy, at least since Plato and Aristotle. In contemporary philosophy, the understanding of these issues has benefited from the formal tools of Classical Extensional Mereology. This paper aims is to defend mereological restrictivism against some constraints imposed by the vagueness argument. To achieve this, the paper is divided into three parts. In the first, I introduce the special composition question (hereafter SCQ) as formulated by [Van Inwagen, 1990] (...) and briefly present the three sets of theories that proffer answers to it. In the second part, I focus on the vagueness argument, that was presented by [Lewis, 1986, ] and [Sider, 2007, ] to defend mereological universalism. In the third section, I introduce the theory of natural properties by David Lewis. From this theory, I propose a new mereological operation labeled as natural fusion. The purpose of this operation is to falsify one of the premises of the vagueness argument. Then, I discuss some examples and counter-examples to natural fusion. (shrink)

In order to understand how the logic of public management can enrich humanistic management’s practices, the current paper will analyze the managerial practices adopted by public administrations within a situation of emergency, a condition where the specific features of the public management can emerge more clearly. Specifically, it will focus on the ways in which the municipality of Bergamo (one of the hardest-hit cities) have reacted to the Covid-19 pandemic, outlining interesting managerial practices especially from the point of view of (...) Humanistic Management’s theory. Such interest resides also in the fact that although the Humanistic Management’s field of research has dealt with a wide range of topics (including human development, emancipation and progress), so far, however, it has not yet considered public administrations, whose role is by definition oriented towards human development through the creation of public value. The analysis of public management through the lens of Humanistic Management can be useful in various respects. Above all, the difference between public administrations and private enterprises can also lead to a very much different process of value creation, based on collaborative forms of production as well as relational and reflexive forms of management. In accordance with the Humanistic Management framework, also business organizations must generate social wellbeing. From this point of view, the lesson of public administrations can be extremely useful for business organization and management alike. (shrink)

I argue in this dissertation that natural properties play a central role in David Lewis' modal realism. To argue in favor of this thesis I present: a bottom-up explanation of a top-down possible world metaphysics; a new definition of natural properties and natural fusion, a new mereological operation. To achieve these aims, in the first chapter, I contextualize the discussion, in the second I resume the discussion about universals in contemporary philosophy and argue that, considering the distinct formulations of the (...) problem, class nominalism combined with modal realism might be the best solution. Furthermore, I discuss Devitt's solution in which he defends that the problem about universals is, in fact, a pseudo problem. In the third chapter, I introduce a minimal ontology of properties, regarding natural properties, I discuss the existing definitions, present a new one and discuss some theories of similarity, a notion that is in the core of the definition I propose. Besides, I present how natural properties benefit the definition of terms of nomological package, linked to its fundamentality role. I also present some applications related to the rationality role that encompass some well-known philosophical problems of the second half of 20th century. In the fourth chapter, I present some varieties of philosophical realism, I consider the theoretical advantages of taking scientific realism as background and I discuss one more utility of natural properties, the solution to the problem of eligibility of reference or, the Putnam's paradox. In the fifth chapter, I discuss how mereology is important to link several aspects of Lewis' modal realism. For such, I discuss the relation between composition as identity and ontological innocence of mereology and I present the natural fusion mereology, a new mereological operation that aims to minimize the problems of unrestricted composition.

Neste artigo analisaremos o problema existencial do consumismo a partir da análise de Zygmunt Bauman e de autores cujas reflexões favoreceram uma frutífera interlocução intelectual, destacando assim a pertinência de tal interpretação ao revelar como a existência humana, na sociedade contemporânea, se encontra submetida aos parâmetros normativos do consumo social.

"A Course on Aesthetics" offers a broad perspective of current scholarship in aesthetics without favouring any one particular school, discipline, or ideology. Written in an elegant and clear style, Barilli's text explores the basic inherent structures of human thought about the classification and evaluation of the arts. Barilli avoids any binding or dogmatic conclusions about artistic assessment in his consideration of both historical and more current art forms such as video and performance art. In doing so, he presents a contemporary (...) account of a scholarly concern. In "A Course on Aesthetics", Barilli examines the aesthetic experience in general, the passage from aesthetics to art, the "user" of art, and the critic. In his brilliant analyses of the phenomenology of various forms of art - from literature to music, from painting to art, from theatre to television - he discusses the relationship between representation and expression, touching on many of the major questions debated in contemporary criticism. A bibliography provides direction for further study of the history of aesthetics as a discipline. Renato Barilli has published numerous books in Italian on poetics, cultural theory, and contemporary art, including "Culturologia e Fenomenologia Degli Stili", L'Arte Contemporanea", and "Il Ciclo Del Postmoderno". The University of Minnesota Press has also published a translation of his "Rhetoric". Karen Pinkus is translator of Giorgio Agamben's "Language and Death". (shrink)

Por que amamos? O que está por trás desse sentimento que, segundo dizem, move montanhas? É se debruçando sobre a filosofia, a ancestralidade, mitos africanos, indígenas, orientais, ocidentais e até sobre a biologia que Renato Noguera nos leva a refletir sobre os diferentes significados do amor. Amar é querer aprender, ensinam-nos os gregos. A esse aprendizado, soma-se outro fundamental, desta vez proveniente de culturas afro-indígenas: amar não é uma emoção individual, mas coletiva, e pode envolver duas, três, quatro pessoas, (...) ou mesmo uma comunidade inteira – o que é explicado também pela biologia. A alquimia de Noguera está em mostrar como os ensinamentos de filósofos e pensadores das mais diversas eras e sociedades não se contradizem, mas complementam-se. Por que amamos? Não há apenas uma resposta – assim como não há apenas uma forma de amor. (shrink)

A Fórmula Porchat — ou seja, a intuição de um conflito das filosofias de caráter indecidível – possui papel tanto propedêutico quanto compulsório para um tratamento não dogmático da história dos sistemas filosóficos. Ao mesmo tempo em que reconhece tal papel, o presente artigo pretende indicar o caráter problemático da correspondência entre “conflito das filosofias” e “indecidibilidade filosófica”. Para tal, sustenta que o sentimento de indecidibilidade filosófica tem como referência impensada uma nostalgia da decidibilidade. O artigo sugere, ainda, o abandono (...) do tema da indecidibilidade, como um falso problema filosófico, e sustenta a necessidade de considerar os efeitos da prática filosófica sobre a configuração da vida comum e de tomar tais efeitos como formas de decidibilidade. Para tal é necessário considerar a atividade filosófica como inscrita no campo maior da manufatura da experiência humana. (shrink)

O propósito deste artigo é o de evidenciar de que forma a afirmação de ser ser-para-a-morte de Heidegger pode ser entendido como condição de possibilidade para a responsabilização do desejo conforme formulado pela psicanálise lacaniana. Primeiro, descreve-se a estrutura do Dasein heideggeriano, bem como seus existenciais. Em seguida, analisa-se o uso e o sentido da noção de desejo em Lacan. Tanto numa existência autêntica, quanto num final de análise, onde o sujeito sabe lidar com suas perdas, diante da angústia, ele (...) assume um papel de protagonista de sua existência e consegue se responsabilizar pelo seu desejo. A análise, nesse sentido, serve como uma ferramenta que possibilita o sujeito lidar com este sofrimento decorrente da falta, deste nada que falou Heidegger. Evidentemente que a análise não objetiva eliminar esta falta ontológica, mas tão somente desconstruir os fantasmas que o sujeito construiu para afastar o que lhe é mais próprio, constitutivo de sua estrutura ontológica, qual seja, sua finitude. Portanto, tanto para Heidegger, por meio da afirmação da angústia frente à morte, quanto para Lacan, onde o sujeito assumiu a tragédia de sua existência – no final de análise –, é a afirmação da finitude que possibilita a responsabilização do desejo, de ser autêntico ou, se preferir, sujeito.

In this study the influence of irrational beliefs and perfectionism on the emergence of competitive anxiety was investigated. While previous studies indicate that higher irrational beliefs predict greater competitive anxiety, in the present study it is hypothesized that this relationship is mediated by perfectionism. A serial atemporal multiple mediation analysis revealed that both adaptive and maladaptive perfectionism were significant partial mediators between irrational beliefs and competitive anxiety. The total score and all four subscale scores on irrational beliefs had both direct (...) and indirect effects on cognitive competitive anxiety, the latter effects mediated by both forms of perfectionism. Depreciation beliefs had a direct effect, and demandingness and awfulizing had indirect effects, on somatic competitive anxiety when both forms of perfectionism were entered as mediators. These findings suggest that both irrational beliefs and perfectionism influence the emergence of competitive anxiety, therefore rational emotive behavioral therapy with a focus upon perfectionism may be an effective means of reducing competitive anxiety in athletes.

Quais são as causas do descontentamento das pessoas com a política, pergunta-se o filósofo Renato Janine Ribeiro na abertura de O Valor Volta à Política, coletânea de artigos escritos entre 2011 e 2015, num momento de forte otimismo com um país que, após consolidar a democracia, parecia destinado a fortalecê-la e se desenvolver. O retrocesso que o atingiu - assim como a outros países - substituiu a política pelo ódio. Mais que o antipetismo, o maior triunfo desse furor foi (...) a antipolítica. Mas o que aconteceu? Será que a vida política se tronou um efeito da vida econômica? Se a cidadania, em nossos dias, realmente foi substituída pelo consumo, então é a subida ou a queda no nível de vida o principal critério para as pessoas decidirem seus votos? É recorrendo ao tempo longo que Janine vai examinar se o apelo democrático simplesmente se esgotou ou se o que estamos vivendo é uma "reação reacionária" dos ressentidos com um mundo em transformação. Observador atento e afiado, o próprio autor revisita esses anos de efervescência tecendo, em 2021 - portanto após a ascensão da extrema-direita -, comentários aos seus artigos. Dos efeitos da crise financeira de 2008 à contestação da legitimidade das eleições de 2014 - que Janine equivale à abertura de uma caixa de Pandora -, passando pelas manifestações de 2013 e pela ascensão das redes sociais, descortinam-se no fio dos anos visões da política brasileira e os possíveis devires de um passado que perdura no presente.
