This paper discusses logical accounts of the notions of consistency and negation, and in particular explores some potential means of defining consistency and negation when expressed in modal terms. Although this can be done with interesting consequences when starting from classical normal modal logics, some intriguing cases arise when starting from paraconsistent modalities and negations, as in the hierarchy of the so-called cathodic modal paraconsistent systems (cf. Bueno-Soler, Log Univers 4(1):137–160, 2010). The paper also takes some first steps in (...) exploring the philosophical significance of such logical tools, comparing the notions of consistency and negation modally defined with the primitive notions of consistency and negation in the family of Logics of Formal Inconsistency (LFIs), suggesting some experiments on their expressive power.

A system is classified as multimodal if its language has more than one modal operator as primitive, and such operators are not interdefinable. We extend the anodic and cathodic modal systems, introduced in Bueno-Soler and Bueno-Soler , to a class of the so-called basilar multimodal systems generating, in this way, the classes of anodic and cathodic multimodal logics. The cathodic multimodal systems are defined as extensions of positive multimodal systems by adding degrees of negation plus consistency operators. In (...) this way, cathodic multimodal systems are logics of formal inconsistency [the paraconsistent LFIs, as treated in Carnielli et al. ] enriched with multimodal operators. We focus the attention on models for such classes of systems and discuss how modal possible-translation semantics, as well as possible-worlds , can be defined to interpret basilar cathodic multimodal systems. While anodic systems are modeled by Kripke models only, we introduce the modal possible-translation models for cathodic systems. Such models, given by combinations of three-valued modal logics, besides their own interest, explain the role of non-trivializing contradictions in multimodal environment. (shrink)

In this paper we extend the anodic systems introduced in Bueno-Soler (J Appl Non Class Logics 19(3):291–310, 2009) by adding certain paraconsistent axioms based on the so called logics of formal inconsistency , introduced in Carnielli et al. (Handbook of philosophical logic, Springer, Amsterdam, 2007), and define the classes of systems that we call cathodic . These classes consist of modal paraconsistent systems, an approach which permits us to treat with certain kinds of conflicting situations. Our interest in this (...) paper is to show that such systems can be semantically characterized in two different ways: by Kripke-style semantics and by modal possible-translations semantics . Such results are inspired in some universal constructions in logic, in the sense that cathodic systems can be seen as a kind of fusion (a particular case of fibring) between modal logics and non-modal logics, as discussed in Carnielli et al. (Analysis and synthesis of logics, Springer, Amsterdam, 2007). The outcome is inherently within the spirit of universal logic, as our systems semantically intermingles modal logics, paraconsistent logics and many-valued logics, defining new blends of logics whose relevance we intend to show. (shrink)

We propose a new approach to positive modal logics, hereby called anodic modal logics. Our treatment is completely positive since the language has neither negation nor any falsum or minimal particle. The elimination of the minimal particle of the language requires introducing the new concept of factual sets and factual deductions which permit us to talk about deductions in the actual world. We start from a positive fragment of the standard system K, denoted by K⊃, ∧, ◊, which is a (...) bimodal system with □ and ◊ as primitive. This system is then extended to a class of fragments of the Lemmon and Scott systems (cf. (Lemmon et al., 1977)), denoted by K⊃, ∧, ◊ + Gk;l;m;n + Gm;n;k;l. It is shown that such classes of systems are characterized with respect to the usual Kripke-style semantics. The proof is by way of a Henkin-style construction, with “possible worlds” being taken to be prime theories as introduced in the modal context by J. M. Dunn in (Dunn, 1995). We also obtain a surprising limiting result showing that the incompleteness phenomenon in modal logic is independent of negation. (shrink)

This paper shows that some classes of multimodal paraconsistent logics endowed with weak forms of negation are incompletable with respect to Kripke semantics. The reach of such incompleteness is discussed, and we argue that this shortcoming, more than just a logical predicament, may be relevant for attempts to characterize quantum logics and to handle quantum information and quantum computation.

This paper introduces the logic of evidence and truth \ as an extension of the Belnap–Dunn four-valued logic \. \ is a slightly modified version of the logic \, presented in Carnielli and Rodrigues. While \ is equipped only with a classicality operator \, \ is equipped with a non-classicality operator \ as well, dual to \. Both \ and \ are logics of formal inconsistency and undeterminedness in which the operator \ recovers classical logic for propositions in its scope. (...) Evidence is a notion weaker than truth in the sense that there may be evidence for a proposition \ even if \ is not true. As well as \, \ is able to express preservation of evidence and preservation of truth. The primary aim of this paper is to propose a probabilistic semantics for \ where statements \\) and \\) express, respectively, the amount of evidence available for \ and the degree to which the evidence for \ is expected to behave classically—or non-classically for \ \). A probabilistic scenario is paracomplete when \ + P 1\), and in both cases, \ < 1\). If \ = 1\), or \ = 0\), classical probability is recovered for \. The proposition \, a theorem of \, partitions what we call the information space, and thus allows us to obtain some new versions of known results of standard probability theory. (shrink)

Bayesian epistemology has close connections to inductive reasoning, accepting the view that inductive inferences should be analyzed in terms of epistemic probabilities. An important precept of Bayesian epistemology is the dynamics of belief change, with change in belief resulting from updating procedures based on new evidence. The inductive relations between evidence E and hypotheses or theories H are essential, particularly the notions of plausibility, confirmation, and acceptability, which are critical but subject to several difficulties. As a non-deductive process, Bayesian reasoning (...) cannot itself be subjected to strict deductive logic, but it can take advantage of an enabling logical environment. The present paper proposes that paraconsistent and paracomplete logics can be helpful for some questions of Bayesian epistemology, even to the point of being relevant in developing a legitimate paraconsistent Bayesian epistemology. By developing a novel probability theory based on the Logic of Evidence and Truth ( $${LET}_{F}$$ ), a logic that deals with evidence for or against a judgment, including contradictory or missing evidence, we allow for the possibility of quantifying the degree of evidence attributed to a proposition through novel probability measures. We illustrate, through examples, some ways to address challenging problems in the area by using paraconsistent and paracomplete paradigms. This topic is of significant interest not only in the philosophy of science but also in Artificial Intelligence and other emerging trends such as probabilistic networks and related models (see Haenni et al. Probabilistic logics and probabilistic networks, volume 350, Springer, Berlin, 2010). (shrink)

This paper defends the use of possibility and necessity models based on the Logics of Formal Inconsistency, taking advantage of their expressivity in terms of the notions of consistency and inconsistency. The present proposal directly generalizes the approach of Besnard and Lang, whose main guidelines we borrow here. Some basic properties of possibility and necessity functions over the Logics of Formal Inconsistency are obtained and it is shown, by revisiting a paradigmatic example, how paraconsistent possibility and necessity reasoning can, in (...) general, attain realistic models for artificial judgement. We will call such models credal calculi, emphasizing some of their appealing consequences. (shrink)

In the last two decades modal logic has undergone an explosive growth, to thepointthatacompletebibliographyofthisbranchoflogic,supposingthat someone were capable to compile it, would?ll itself a ponderous volume. What is impressive in the growth of modal logic has not been so much the quick accumulation of results but the richness of its thematic dev- opments. In the 1960s, when Kripke semantics gave new credibility to the logic of modalities? which was already known and appreciated in the Ancient and Medieval times? no one could (...) have foreseen that in a short time modal logic would become a lively source of ideas and methods for analytical philosophers,historians of philosophy,linguists, epistemologists and computer scientists. The aim which oriented the composition of this book was not to write a new manual of modal logic buttoo?ertoeveryreader,evenwithnospeci?cbackground in logic, a conceptually linear path in the labyrinth of the current panorama of modal logic. The notion which in our opinion looked suitable to work as a compass in this enterprise was the notion of multimodality, or, more speci?cally, the basic idea of grounding systems on languages admitting more than one primitive modal operator.

“Trends in Logic XVI: Consistency, Contradiction, Paraconsistency, and Reasoning - 40 years of CLE” is being organized by the Centre for Logic, Epistemology and the History of Science at the State University of Campinas (CLEUnicamp) from September 12th to 15th, 2016, with the auspices of the Brazilian Logic Society, Studia Logica and the Polish Academy of Sciences. The conference is intended to celebrate the 40th anniversary of CLE, and is centered around the areas of logic, epistemology, philosophy and history of (...) science, while bringing together scholars in the fields of philosophy, logic, mathematics, computer science and other disciplines who have contributed significantly to what Studia Logica is today and to what CLE has achieved in its four decades of existence. It intends to celebrate CLE’s strong influence in Brazil and Latin America and the tradition of investigating formal methods inspired by, and devoted to, philosophical views, as well as philosophical problems approached by means of formal methods. The title of the event commemorates one of the three main areas of CLE, what has been called the “Brazilian school of paraconsistency”, combining such a pluralist view about logic and reasoning.

In this paper I identify two different lockean concepts of justice - "proprietary justice" and "justice as fairness" - and examine the relationship between each of them and charity in John Locke´s theory of property. As I try to show, in both cases Locke considers that charity may have priority over justice. This undermines the classical interpretation of Locke as a defender of unlimited capitalistic appropriation and provides additional evidence supporting Locke´s acceptation of a minimal redistributive system which should guarantee (...) the material welfare of non-appropriators.

According to the trivialist, everything is true. But why would anyone believe that? It turns out that trivialism emerges naturally from a certain inconsistency view of language, and it has significant benefits that need to be acknowledged. But trivialism also encounters some troubles along the way. After discussing them, I sketch a couple of alternatives that can preserve the benefits of trivialism without the corresponding costs.

This article brings together two debates in contemporary political philosophy: on the one hand, the dispute between the distributive and relational approaches to equality and, on the other hand, the field of intergenerational equality. I offer an original contribution to the second domain and by doing so, I inform the first. The aim of this article is thus twofold: (1) shedding some light on an under-researched and yet crucial question – ‘which inequalities between generations matter?’ and (2) contributing to a (...) far-reaching debate that touches upon the nature of egalitarianism. After showing that there are two key problems that fall within the scope of intergenerational equality – questions of justice between age groups and questions of equality between birth cohorts – I argue that, contrary to what the default distributive view (complete lives egalitarianism) states, some inequalities between age groups matter independently of their diachronic impact, and so partly for relational reasons. I argue that, even if we are distributive egalitarians, we must endorse the relational egalitarian conception to successfully make sense of some inequalities between age groups. I infer from this both that the putative view that the ‘relational’ conception of equality can be redescribed as distributive must be rejected and that the distributive view requires supplementation (but not necessarily displacement) by the relational view.

Thirteen up-and-coming researchers in the philosophy of mathematics have been invited to write on what they take to be the right philosophical account of mathematics, examining along the way where they think the philosophy of mathematics is and ought to be going. A rich and diverse picture emerges. Some broader tendencies can nevertheless be detected: there is increasing attention to the practice, language and psychology of mathematics, a move to reassess the orthodoxy, as well as inspiration from philosophical logic.

As denominadas filosofias do _hen kai pan_tiveram um papel determinante no pensamento alemão do século XVIII e XIX, em boa parte devido ao tratamento que lhes foi dado por F. H. Jacobi em _Sobre a doutrina de Espinosa em cartas ao senhor Moses Mendelssohn _. Espinosa e Giordano Bruno são os grandes representantes desse modo de pensar, e suas filosofias inauguram uma nova articulação entre causa e razão, mundo e Deus. Jacobi identifica em ambos o modelo da máxima coerência intelectual (...) que uma filosofia pode alcançar, um monismo imanente cuja consistência lógica não pode ser combatida no interior do sistema com as armas da metafísica pura. Por outro lado, é no princípio indeterminado, comum a essas doutrinas, que Jacobi verá a confirmação de uma danosa tendência da história da filosofia que culmina no idealismo de Fichte e na filosofia do jovem Schelling, isto é, na união entre natureza naturada e naturante no eu.

Christine de Pizan da vida a su gobernante ideal a partir de la tradición medieval del aristotelismo político y su noción de lo “arquitectónico”. Construido a modo de una arquitectura viviente de ciencias, el rey sabio aparece dominando la paleta de saberes, que va desde la episteme hasta los conocimientos más prácticos. Teoría y práctica se encuentran, así, en la base de su construcción de lo político. Pero ¿en qué medida la autora se consagra a brindar una explicación del pasaje (...) de las ciencias, sobre todo, aquel que va de las especulativas al registro práctico de la ciencia política? Si el rey se distingue por ser un sabio al tiempo que un experto en las diversas ciencias, cabe preguntarse si acaso la autora teoriza sobre dicho pasaje de lo teórico a lo práctico que constituye la esencia de su pensamiento. ¿Cuál es el canal para volcar la episteme al servicio del Estado? Al respecto, sostengo la hipótesis de que tanto la prudencia como el entendimiento o intelecto parecen ser los dos componentes de la sabiduría perfecta que la escritora aúna en una perfecta díada; operación, esta, que le permite explicar el pasaje de todas las ciencias al plano de lo contingente. ¿Acaso no es, gracias a esta operación, que el rey sabio de Christine de Pizan aparece como el intelecto supremo de la comunidad política, encarnada en el reino de Francia? ¿No son las ciencias, de este modo, redituables en servicio del Estado?

The World Health Organization has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants from all Spanish regions completed the survey. Binomial (...) logistic regressions adjusted for socioeconomic characteristics, body mass index, previous HRBs, and confinement context were conducted to investigate associations between the number of weeks confined and a set of six HRBs. When adjusted, we observed significantly lower odds of experiencing a higher number of HRBs than before confinement overall in a time-dependent fashion: OR 0.63; 95% CI: 0.49–0.81 for the second and OR 0.47; 95% CI: 0.36–0.61 for the third week of confinement. These results were equally consistent in all age and gender subgroup analyses. The present study indicates that changes toward a higher number of HRBs than before confinement, as well as the prevalence of each HRB except screen exposure, decreased during the first 3 weeks of COVID-19 confinement, and thus the Spanish adult population may have adapted to the new situational context by gradually improving their health behaviors.

In this paper, 1 examine the role of the delta function in Dirac’s formulation of quantum mechanics (QM), and I discuss, more generally, the role of mathematics in theory construction. It has been argued that mathematical theories play an indispensable role in physics, particularly in QM [Colyvan, M. (2001). The inrlispensability of mathematics. Oxford University Press: Oxford]. As I argue here, at least in the case of the delta function, Dirac was very clear about its rlispensability. I first discuss the (...) significance of the delta function in Dirac’s work, and explore the strategy that he devised to overcome its use. l then argue that even if mathematical theories turned out to be indispensable, this wouidn’t justify the commitment to the existence of mathematical entities. In fact, even in successful uses of mathematics, such as in Dirac’s discovery of antimatter, there’s no need to believe in the existence of the corresponding mathematical entities. An interesting picture about the application of mathematics emerges from a careful examination of Dirac’s work. (shrink)

Histories of psychoanalysis largely respect the boundaries drawn by the psychoanalytic profession, suggesting that the development of psychoanalytic theories and techniques has been the exclusive remit of professionally trained analysts. In this article, I offer an historical example that poses a challenge to this orthodoxy. Based on extensive archival material, I show how British psychiatric social workers, a little-studied group of specialist mental hygiene workers, advanced key organisational, observational, and theoretical insights that shaped mid-century British psychoanalysis. In their daily work (...) compiling patient histories, conducting home visits, and interviewing the parents of ‘maladjusted’ children, psychiatric social workers were uniquely positioned to expose the importance of family relationships in the development of childhood neuroses. As this article details, their analytic attention to these dynamics not only influenced, but fundamentally constituted the innovative research on maternal-child relationships and family therapy pioneered by eminent psychoanalyst John Bowlby. In addition, psychiatric social workers produced and published independent psychoanalytic research, and fiercely debated the limitations of analytic concepts such as transference. In presenting the relationship between British psychiatric social work and psychoanalysis, this article suggests a new way of telling the history of both. (shrink)

Business Ethics: A European Review, EarlyView.

An account of scientific representation in terms of partial structures and partial morphisms is further developed. It is argued that the account addresses a variety of difficulties and challenges that have recently been raised against such formal accounts of representation. This allows some useful parallels between representation in science and art to be drawn, particularly with regard to apparently inconsistent representations. These parallels suggest that a unitary account of scientific and artistic representation is possible, and our article can be viewed (...) as laying the groundwork for such an account—although, as we shall acknowledge, significant differences exist between these two forms of representation.

How is that when scientists need some piece of mathematics through which to frame their theory, it is there to hand? What has been called 'the unreasonable effectiveness of mathematics' sets a challenge for philosophers. Some have responded to that challenge by arguing that mathematics is essentially anthropocentric in character, whereas others have pointed to the range of structures that mathematics offers. Otavio Bueno and Steven French offer a middle way, which focuses on the moves that have to be (...) made in both the mathematics and the relevant physics in order to bring the two into appropriate relation. This relation can be captured via the inferential conception of the applicability of mathematics, which is formulated in terms of immersion, inference, and interpretation. In particular, the roles of idealisations and of surplus structure in science and mathematics respectively are brought to the fore and captured via an approach to models and theories that emphasize the partiality of the available information: the partial structures approach. The discussion as a whole is grounded in a number of case studies drawn from the history of quantum physics, and extended to contest recent claims that the explanatory role of certain mathematical structures in scientific practice supports a realist attitude towards them. The overall conclusion is that the effectiveness of mathematics does not seem unreasonable at all once close attention is paid to how it is actually applied in practice. (shrink)

David Bohm and the challenge of a fragmented society.

The Health System Food and Nutrition Units are designed to produce and offer balanced meals, establishing dietary patterns, maintaining and restoring the health of the individual. The control of dirty in leftover ingestion can lower costs and organic waste. The objective of the study is to quantify and analyze the leftover intake i meals served to patients, and ingestion of dirty leftovers in collective meals of a Food and Nutrition Unit, located in the Southwest of Paraná. The data were collected (...) in two weeks, being developed in two stages. The first was the determination of the leftover ingestion and dirty remains of the healthy collective, and the second quantification of the rest intake by the patients community. Two scales were used to obtain the total weight of the food distributed in the cafeteria. Vats were weighed, before and after lunch. The garbage bags were weighed in order to quantify the leftover ingestion. The results of total leftovers showed an average of 44.71 kg / day, with a percentage of 44.19% being unacceptable. The leftover intake presented 8.72%, being classified as bad with this waste331 people could be fed. In order to measure the leftover intake by the diseased community, the weights of three lunch boxes were collected; the number of boxes wss added, resulting in kilos of food distributed for the day. Weighing the bags of garbage, was 19.02 kg / day, representing 28.36% of leftover ingestion, being above the acceptable of up to 20%. Based on this data, 148 people could be fed, making it necessary to take in consideration organoleptic criteria, satisfaction surveys, their preferences and nutritional needs, both for the healthy and the diseased group.

A exposição tem como ponto de partida a leitura hegeliana de Jacobi, exposta na obra mais madura Enciclopédia das ciências filosóficas de 1827-1830, a respeito do saber imediato e, consequentemente, da oposição entre crença e saber. A finalidade da comparação é evidenciar o que Jacobi de fato entende por “saber imediato” em oposição ao saber mediato e mostrar por que a crença não pode ser meramente subjetiva — como foi e é ainda largamente interpretado — e sobretudo por que individualidade (...) não é sinônimo de subjetividade como queria Hegel. Afinal, as dificuldades e equívocos da leitura hegeliana servem para entender melhor os próprios conceitos de Jacobi. (shrink)

São três as questões básicas às quais se dedica este artigo. Primeiramente, perguntamos: Por que seria a liberdade de pensamento e expressão uma condição necessária à paz social? As respostas que nos provê Spinoza nos ajudarão a compreender o grave erro político que é condenar ao exílio, à prisão ou à morte aqueles cujo pensamento confronta o regime estabelecido. Entre os raros casos de indivíduos que mantêm sua honestidade quando esta lhes impõe o risco da morte, destacamos o de Sócrates. (...) As supostas palavras deste filósofo legendário nos levarão a uma segunda discussão: Pode a razão determinar a honestidade mesmo quando esta implica a morte do próprio indivíduo? Não estaria a razão opondo-se assim ao próprio conatus? Por fim, das considerações sobre o vínculo entre indivíduo e coletividade, ética e política, surgirá a questão: Como se relacionam amor próprio, amor aos outros e amor à Natureza? (shrink)

Resumo: Este artigo analisa o problema de determinar o sujeito político do feminismo, uma vez que a categoria “mulher” passa a ser questionada e interpretada de diferentes formas, na teoria feminista contemporânea. Após apresentar brevemente as críticas ao essencialismo, por parte de autoras bastante influentes do Norte global, investigam-se os argumentos de pensadoras que defendem um viés descolonial. Sustenta-se que a perspectiva descolonial precisa ser levada em consideração, no momento de buscar categorias de análise adequadas ao movimento feminista, no contexto (...) do Sul global, respeitando-se suas particularidades históricas e sociopolíticas.: This paper analyses the problem of determining who constitutes the feminist political subject, since the contemporary feminist theory inquires the existence of “woman” as a category and interprets it in different ways. First, I briefly introduce the critiques to essentialism by influential authors from the Global North, then I investigate the arguments from thinkers who advocate a decolonial point of view. I sustain that we must take the decolonial perspective into consideration, which is crucial to find categories of analysis apropriate to the feminist movement in the context of the Global South, in order to respect its historical and socio-political particularities.

Tem-se como objetivo deste artigo problematizar a questão da dissolução da subjetividade tal como aparece na obra-prima de Nietzsche, O Nascimento da Tragédia, ou Helenismo e Pessimismo, focando, sobretudo, nos capítulos introdutórios 3, 4 e 5. Ao longo de nosso estudo será analisado o percurso argumentativo que permitiu a Nietzsche abrir mão do sujeito centrado doador de sentido para propor, na verdade, seu completo desfazimento através da contemplação estética da arte dionisíaca. Conclui-se que o pensamento de Nietzsche se dá de (...) tal maneira porque é enviesado em uma visão estética de mundo na qual a dicotomia sujeito e objeto não se aplica por completo. (shrink)

Cramer et al.'s network approach reconceptualizes mental comorbidity on the basis of symptom space originating from psychometric signatures. We argue that the advantages of this approach need to be regarded in the context of the multi-level functional organization of the neural substrate, ranging from neurogenetic to psychometric. Neuroelectric oscillations are proposed as a level-integrating principle.
