In this review, we present a rigorous construction of an algebraic method for quantum unstable states, also called Gamow states. A traditional picture associates these states to vectors states called Gamow vectors. However, this has some difficulties. In particular, there is no consistent definition of mean values of observables on Gamow vectors. In this work, we present Gamow states as functionals on algebras in a consistent way. We show that Gamow states are not pure states, in spite of their representation (...) as Gamow vectors. We propose a possible way out to the construction of averages of observables on Gamow states. The formalism is intended to be presented with sufficient mathematical rigor. (shrink)

We review some results in the theory of non-relativistic quantum unstable systems. We account for the most important definitions of quantum resonances that we identify with unstable quantum systems. Then, we recall the properties and construction of Gamow states as vectors in some extensions of Hilbert spaces, called Rigged Hilbert Spaces. Gamow states account for the purely exponential decaying part of a resonance; the experimental exponential decay for long periods of time physically characterizes a resonance. We briefly discuss one of (...) the most usual models for resonances: the Friedrichs model. Using an algebraic formalism for states and observables, we show that Gamow states cannot be pure states or mixtures from a standard view point. We discuss some additional properties of Gamow states, such as the possibility of obtaining mean values of certain observables on Gamow states. A modification of the time evolution law for the linear space spanned by Gamow shows that some non-commuting observables on this space become commuting for large values of time. We apply Gamow states for a possible explanation of the Loschmidt echo. (shrink)

El presente artículo busca establecer el origen y desarrollo del concepto de ley natural en Tomás de Aquino, especialmente la relación que se establece entre razón y voluntad. Recordemos que esta relación ha sido objeto de numerosos estudios, especialmente en referencia al mismo concepto en Francisco Suárez.

Al calificarlo como teólogo, entendemos desde dónde está hablando, es decir, desde (...) su condición de creyente y teniendo como fuente la misma Revelación. (shrink)

People have disagreed on the significance of Libet-style experiments for discussions about free will. In what specifically concerns free will in a libertarian sense, some argue that Libet-style experiments pose a threat to its existence by providing support to the claim that decisions are determined by unconscious brain events. Others disagree by claiming that determinism, in a sense that conflicts with libertarian free will, cannot be established by sciences other than fundamental physics. This paper rejects both positions. First, it is (...) argued that neuroscience and psychology could in principle provide support for milder deterministic claims that would also conflict with libertarian free will. Second, it is argued that Libet-style experiments—due to some of their peculiar features, ones that need not be shared by neuroscience as a whole—currently do not support such less demanding deterministic claims. The general result is that neuroscience and psychology could in principle... (shrink)

This paper is a critical review of the most relevant studies about the Levinasian concept of passivity. The purpose is to follow the way in which Levinas’s scholars have dealt with the following aspects: the relation between ethical passivity and the possibility of effective ethical agency, the origin of passivity, and the validity of ethical passivity in the public sphere. As a starting point for future research, I finally argue that the best way to read Levinas’s passive ethics is through (...) the dynamism between maximums and minimums present within it. This means that without sacrificing the omni comprehensive view of divine revelation and Jewish tradition, Levinas presents ethics as rationally understandable by everyone and philosophically defensible. Despite being biblically based, Levinas does not appeal to authority in supporting his view, he is confident in arguing rationally. This account could place Levinas in the way of public ethics, which consists in an ethos shared by all members of democratic societies. These minimums of justice could be the way to universalize Levinas’s ethics. (shrink)

From Gadamer's Habilitation thesis, “Plato’s dialectical ethics. Phenomenological Interpretations Relating to the Philebus” (1928), this article seeks to highlight the fundamental lines of Plato’s image, outlined in that author’s first philosophical publication (1931). The confrontation with the themes of ethics and dialectic, in the current state of Platonic studies, indicates that in Plato’s image drawn in the early confrontation with the Philebus, clearly influenced by the phenomenological notion of Dasein, one already finds the fundamental features of what will become Gadamer's (...) philosophical hermeneutics, fully emancipated from Heideggerian tutelage.

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Interreligious and intercultural dialogue is supposed to be the best way to solve the conflicts arising from rival religious hermeneutics and different modes to conceive the ideal of a good life in contemporary multicultural and pluralistic societies. In regard to communicative or dialogical reason, respectful coexistence can be reached only by argumentative communication between interested people. In this sense, only rational arguments, strong enough to pass the test of the shared rationality can be valid at a discursive level. However, Jewish (...) philosopher Emmanuel Levinas and Catholic theologian Johann Baptist Metz challenge the symmetrical and rational-based dialogue in order to postulate an asymmetrical relation by giving voice to the other. For them, the core of interreligious and intercultural engagement does not start from rational agreements as Habermas, for instance, has proposed; but from prophetic and anamnestic reasons. (shrink)

In a previous paper, I argued that neuroscience and psychology could in principle undermine libertarian free will by providing support for a subset of what I called “statements of local determination.” I also argued that Libet-style experiments have not so far supported statements of that sort. In a commentary to the paper, Adina Roskies and Eddy Nahmias accept the claim about Libet-style experiments, but reject the claim about the possibilities of neuroscience. Here, I explain why I still disagree with their (...) conclusion, despite being sympathetic to a lot of what they say in support of it. (shrink)

Free will skepticism is the view that people never truly deserve to be praised, blamed, or punished for what they do. One challenge free will skeptics face is to explain how criminality could be dealt with given their skepticism. This paper critically examines the prospects of implementing legal changes concerning crime and punishment derived from the free will skeptical views developed by Derk Pereboom and Gregg Caruso. One central aspect of the changes their views require is a concern for reducing (...) the severity of current forms of punishment. The paper considers two strategies for pursuing such a reduction. By taking into account evidence from the psychology of belief in free will and desire to punish, it is argued that a strategy aiming at a reduction of people’s natural desire to punish criminals can be successful if capable of providing alternatives to current forms of punishment satisfying three properties: they must be less harmful than current forms of punishment, more effective in preventing crime, and incompatible with current forms of punishment.

La administración científica de la educación ha llevado a que las instituciones educativas muestren en los últimos años un marcado interés por los rankings, la rendición de cuentas y por una educación de calidad basada en la excelencia individual. Frente a esta dinámica, el presente trabajo muestra que las exigencias de una sociedad que ha venido de experiencias conflictivas o que quiere formar ciudadanos solidarios, requieren un cambio de perspectiva desde la autonomía individual hacia la construcción de escenarios de cooperación (...) y respeto por el otro. Mediante un análisis teórico, este artículo muestra la insuficiencia del modelo taylorista de educación y propone una educación para la incertidumbre como apertura hacia la cooperación y la solidaridad.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

El artículo muestra la estrecha conexión existente entre el concepto de ética y el de tiempo mesiánico en la filosofía de Emmanuel Lévinas. Esto significa que la respuesta ética se da en un tiempo discontinuo en el que –además de romper la continuidad del tiempo ininterrumpido del progreso– el sujeto se convierte en el mesías que responde al sufrimiento del otro. Para lograr este propósito, el trabajo muestra la crítica de Lévinas a la historia ontológica como olvido de lo singular; (...) posteriormente presenta la posición intermedia entre la perspectiva ontológica y la mesiánica representada en el punto de vista de Bergson, para mostrar luego cómo –para Lévinas– es en la tradición judía donde es posible encontrar una respuesta ética al sufrimiento del otro en el ahora del tiempo mesiánico.

Grappling with the marginalization of the marginal in Western thinking, this paper sets up a dialogue between Emmanuel Levinas’s philosophy and Johann Baptist Metz’s political theology in order to learn from their thoughts on the suffering of victims. For both Levinas and Metz, the idea of theodicy as an explanation of suffering is linked to the ontological conception of time and history, and therefore useless and unjustifiable by nature. The essential question of this research is how to give meaning to (...) the concrete suffering of humanity in order to redeem history from the concept of an evolutionary progress which limits the possibility of hearing the cries of the victims of history. This article will show how Levinas’s and Metz´s rejection of traditional theodicy is closely related to the concepts of memory and history and, therefore, the paper will demonstrate how traditional theodicy becomes for both thinkers an ethical theodicy. Consequently, the ethical account of theodicy replaces the attempt to negotiate the goodness and power of God with the pain of human beings. From this perspective, ethics is shaped by a response to the cry of victims which summons the subject to understand freedom as limited and subordinated to ethical responsibility. In responding to suffering, philosophy and theology can meet beyond idealism and dogmatism. (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

In the last few decades, the literature on moral responsibility has been increasingly populated by scientific studies. Studies in neuroscience and psychology, in particular, have been claimed to be relevant for discussions about moral responsibility in a number of ways. And at the same time, there is not yet a systematic understanding of the sort of questions a science of moral responsibility is supposed to answer. This paper is an attempt to move toward such an understanding. I discuss three models (...) for framing scientific questions relevant to an investigation of moral responsibility. The favored model—the Enhancement model—proposes that a science of moral responsibility has two descriptive tasks. First, science can describe the causes and effects of the many sorts of responses that constitute the human practices of moral responsibility, such as praise, blame, and punishment. And, second, science can describe how modifications aiming at the improvement of such practices can be achieved. Relatively to the other models to be considered, the Enhancement model is broader in scope and less tied to the traditional philosophical agenda on moral responsibility. (shrink)

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

Although the controversy between Malthus and Ricardo has long been considered to be an important source for the history of economic thought, it has hardly been the object of a careful study qua controversy, i.e. as a polemical dialogical exchange. We have undertaken to fill this gap, within the framework of a more ambitious project that places controversies at the center of an account of the history of ideas, in science and elsewhere. It is our contention that the dialogical co-text (...) is essential for reconstructing the meaning and the evolution of science. In the present paper we try to substantiate this contention by means of a pragma-rhetorical study of this particular controversy. First, we reconstruct, through an analysis of a chunk of the correspondence, a micro-level of specific moves and countermoves which constitute a sequential structure within which also meta-scientific and meta-controversial considerations play a role. We then move to a macro-level of analysis, looking for recurrent patterns of argumentation. Finally, we draw epistemological conclusions on the nature of rationality and progress as manifested in actual scientific controversies. (shrink)

Judging a person as morally responsible involves believing that certain responses (such as punishment, reward, or expressions of blame or praise) can be justifiably directed at the person. This paper develops an account of the evolution of moral responsibility judgment that adopts Michael Tomasello’s two-step theory of the evolution of morality and borrows also from Christopher Boehm’s work. The main hypothesis defended is that moral responsibility judgment originally evolved as an adaptation that enabled groups of cooperative individuals to hold free (...) riders responsible more safely by acting in a coordinated way.

Diana Pérez criticizes Davidson’s argument for the thesis that there is no thought without language, and offers an alternative defense of that thesis on the basis of empirical studies on developmental psychology.

At the end, I offer a sketch of how a weaker (...) and more tenable version of the argument could be articulated. (shrink)

La obra de Lévinas propone asumir la ética como Filosofía Primera. Allí convergen dos fuentes de inspiración filosófica, el pensamiento judío y la fenomenología, y la experiencia histórica de persecución, violencia y desconocimiento del otro que exigió a Lévinas criticar el totalitarismo ontológico griego con el propósito de hacer justicia a la Alteridad y dar primacía así a la Responsabilidad para con el Otro sobre la Libertad autónoma del Yo. Luego, el autor retorna la crítica de Lévinas a la fenomenología (...) de la conciencia y a la ontología hermenéutica de Heidegger, con la que Occidente lleva a término su limitada opción por el conocimiento y la manifestación del Ser.

This paper focuses on Gilberto Gomes’ work on free will. In a series of contributions that have had a significant impact on the respective literature, Gomes developed a conception about free will and argued that its existence is consistent with recent scientific findings, specially in neuroscience. In this paper, I object to a claim of Gomes about his conception of free will, namely the claim that it is a compatibilist conception. I seek to show that Gomes does not use the (...) term ‘compatibilism’ as it is usual in the contemporary literature on free will, i.e., as the thesis that free will can exist even if determinism is true. Moreover, the conception of free will Gomes proposes actually has an incompatibilist commitment. I argue that, more than a mere terminological point, acknowledging the incompatibilist aspect of Gomes’ view motivates important questions about the details of the view and helps to reveal a limitation of his defense of the existence of free will. [Este artigo tem como tema o trabalho de Gilberto Gomes sobre o livre-arbítrio. Em uma série de contribuições que tiveram um impacto significativo na respectiva literatura, Gomes elaborou uma concepção sobre o livre-arbítrio e argumentou que sua existência é consistente com descobertas científicas recentes, especialmente na neurociência. Neste artigo, questiono uma afirmação de Gomes sobre sua concepção sobre o livre-arbítrio, a saber, que se trata de uma concepção compatibilista. Busco mostrar que Gomes não usa o termo ‘compatibilismo’ como é habitual na literatura contemporânea sobre o livre-arbítrio, isto é, como a tese segundo a qual o livre-arbítrio pode existir ainda que o determinismo seja verdadeiro. Ademais, a concepção sobre o livre-arbítrio desenvolvida por Gomes tem, efetivamente, um compromisso incompatibilista. Argumento que, mais do que uma mera elucidação terminológica, reconhecer o elemento incompatibilista presente na proposta de Gomes suscita questões importantes sobre os detalhes da proposta e também ajuda a reconhecer uma limitação de sua defesa da existência do livre-arbítrio.].

Abstract: The Pull Bayesian Significance Test (FBST) for precise hy- potheses is applied to a Multivariate Normal Structure (MNS) model. In the FBST we compute the evidence against the precise hypothesis. This evi- dence is the probability of the Highest Relative Surprise Set (HRSS) tangent to the sub-manifold (of the parameter space) that defines the null hypothesis. The MNS model we present appears when testing equivalence conditions for genetic expression measurements, using micro-array technology.

The dissertation has two parts, each dealing with a problem, namely: 1) What is the most adequate account of fuzziness -the so-called phenomenon of vagueness?, and 2) what is the most plausible solution to the sorites, or heap paradox? I will try to show that fuzzy properties are those which are gradual, amenable to be possessed in a greater or smaller extent. Acknowledgement of degrees in the instantiation of a property allows for a gradual transition from one opposite to the (...) other, each intermediate stage constituting an overlap in certain proportion of both contraries. Hence, degrees in the possession of a property give rise to simple contradictions. The reason why I have chosen those two questions is that they provide the main philosophical motivation for a particular brand of an infinite valued and paraconsistent logic. I will claim that Classical logic (CL) is not adequate to handle fuzzy situations, and, being deficient, is in need of being expanded to make room for degrees of truth and weak contradictions. One can hardly deny the importance of the debate, since what is ultimately at stake is what the limits of truth, rationality, intelligibility and possibility are. The main disciplines within which the research moves are the philosophy of language, philosophy of logic, and ontology. (shrink)

In abstract algebraic logic, many systems, such as those paraconsistent logics taking inspiration from da Costa's hierarchy, are not algebraizable by even the broadest standard methodologies, as that of Blok and Pigozzi. However, these logics can be semantically characterized by means of non-deterministic algebraic structures such as Nmatrices, RNmatrices and swap structures. These structures are based on multialgebras, which generalize algebras by allowing the result of an operation to assume a non-empty set of values. This leads to an interest in (...) exploring the foundations of multialgebras applied to the study of logic systems. -/- It is well known from universal algebra that, for every signature Sigma, there exist algebras over Sigma which are absolutely free, meaning that they do not satisfy any identities or, alternatively, satisfy the universal mapping property for the class of Sigma-algebras. Furthermore, once we fix a cardinality of the generating set, they are, up to isomorphisms, unique, and equal to algebras of terms (or propositional formulas, in the context of logic). Equivalently, the forgetful functor, from the category of Sigma-algebras to Set, has a left adjoint. This result does not extend to multialgebras. Not only multialgebras satisfying the universal mapping property do not exist, but the forgetful functor U, from the category of Sigma-multialgebras to Set, does not have a left adjoint. -/- In this paper we generalize, in a natural way, algebras of terms to multialgebras of terms, whose family of submultialgebras enjoys many properties of the former. One example is that, to every pair consisting of a function, from a submultialgebra of a multialgebra of terms to another multialgebra, and a collection of choices (which selects how a homomorphism approaches indeterminacies), there corresponds a unique homomorphism, what resembles the universal mapping property. Another example is that the multialgebras of terms are generated by a set that may be viewed as a strong basis, which we call the ground of the multialgebra. Submultialgebras of multialgebras of terms are what we call weakly free multialgebras. Finally, with these definitions at hand, we offer a simple proof that multialgebras with the universal mapping property for the class of all multialgebras do not exist and that U does not have a left adjoint.

In the current debate in political philosophy, the so-called communitarian thinkers intend to offer an alternative to the dominant liberal thought.

Resumo: Em décadas recentes, a investigação filosófica sobre a responsabilidade moral e o livre-arbítrio, que por muito tempo foi vista como um empreendimento principalmente teórico, passou a também incluir preocupações de tipo mais prático. Essa mudança é bem ilustrada pela proposta cética desenvolvida por autores como Derk Pereboom e Gregg Caruso. Seus trabalhos não apenas negam que sejamos agentes livres e moralmente responsáveis (em um sentido específico dos termos em questão), mas também defendem reformas na maneira como a responsabilização é (...) efetivada em nossas relações interpessoais e, especialmente, no sistema penal. Este artigo examina as implicações práticas do ceticismo de Pereboom e Caruso, principalmente no que diz respeito à sua implementabilidade. Argumento que o núcleo propriamente cético da proposta é inviável para seres humanos com a psicologia moral que temos, mas que, apesar disso, alguns elementos da proposta são compatíveis com uma proposta não-cética focada no aperfeiçoamento das práticas punitivas. Abstract: In recent decades, the philosophical investigation of moral responsibility and free will, which for a long time was seen as a mostly theoretical enterprise, became also the place of more practically oriented concerns. The skeptical view developed by Derk Pereboom and Gregg Caruso is a good illustration of the change. In their work, they not just deny that we are free and morally responsible agents (in a specific sense of the relevant terms) but also propose the reform of responsibility practices as they figure in our interpersonal relations and, especially, in the criminal justice system. This paper examines the practical implications of Pereboom and Caruso’s skepticism, particularly in what concerns its likelihood of being implemented. I argue that the strictly skeptical core of their proposal is not viable for human beings with a moral psychology like ours, but that some elements are nonetheless consistent with a non-skeptical view focused on the improvement of punitive practices.

[Note: articles 1-5 are in English; Intro, Discussion, and Conclusion are in Portuguese.] Responsibility practices that are part of our daily lives involve, among other things, standards about how one should praise, blame, or punish people for their actions, as well as particular acts that follow those standards to a greater or lesser extent. A classical question in philosophy asks whether human beings can actually be morally responsible for what they do. This dissertation argues that addressing this classical question is (...) insufficient if one wants the investigation of moral responsibility to serve the goal of improving ordinary responsibility practices. As an alternative, I offer directions for an interdisciplinary investigation that I take to be in a better position to promote that goal. My argument is developed in five articles and a discussion section. The first four articles describe limitations of skeptical views, which deny the existence of moral responsibility. The first article assesses a skeptical argument based on results from neuroscience that intends to show that there is no free will. I argue that a premise in the argument—which says that choices are determined by events in the brain—is not supported by the available results. The second article argues that, despite the fact that existent results do not show that choices are determined by brain events, further studies in neuroscience could in principle do that. The third article begins the discussion of limitations that concern the implementability of some of the changes in responsibility practices recommended in skeptical approaches. Specifically, I describe challenges that attempts to reduce the severity of legal punishment are likely to face due to psychological facts about belief in free will and desire to punish. The forth article presents results from an original experiment that sought to test a hypothesis about the workings of belief in free will and the desire to punish, namely the hypothesis that the desire to punish causally affects beliefs about free will. Results failed to support the hypothesis. Finally, the fifth article presents what I call the enhancement model, i.e., a proposal about how to structure an interdisciplinary investigation that can promote the enhancement of ordinary responsibility practices. The final discussion section shows how the enhancement model overcomes some of the limitations of recent discussions about the existence of moral responsibility, which includes not just the skeptical views considered in earlier articles, but also views that affirm the existence of moral responsibility and free will. The central claim of this dissertation, therefore, is that the investigation of moral responsibility can be rearranged so as to further the goal of improving ordinary responsibility practices.

Muito se ouve falar em cidadão, ser cidadão, direitos e deveres do cidadão, bem como atuar ativamente enquanto cidadão. Porém, inúmeras pessoas ignoram esse tão complexo, profundo e importante termo.

Logo, nos foi necessário realizar procedimentos e movimentos historiográficos e de filosofia da linguagem, indo a Grécia e Roma Antigas, no qual foram configurando o termo em suas origens e legando para as posteridades, inclusive para nós brasileiros. Sendo assim, fizemos o esforço de buscar as origens do termo, conceito e aplicabilidade no social partindo brevemente da Grécia e Roma Antiga, e relacionando-o com a realidade e aspectos da linguagem, inclusive sua relação com o processo contemporâneo, no qual nos movem a indagar quais problemas envolvem o termo, prática, direitos do cidadão e ou ser cidadão, onde surgem questões também como se há algum problema de semântica, de conceito, falta de entendimento do termo ou uma economia da concretude e aplicabilidade. Bem como, se há cidadãos de primeira, segunda e terceira categoria. Anacronismos ou resgates dos significados e sentidos? E o que dizer da exclusão das mulheres, negros, indígenas, crianças e outros da investidura como cidadãos?

A história humana possui seus processos e especificidades no e do tempo e espaço, com certas rupturas e continuidades de certos processos e elementos. Podemos citar como exemplo: Os tipos e modos de desigualdades, sistemas escravistas e sistemas coloniais etc. Mas, não sendo igual ou da mesma forma.

Desse modo, como já mencionado, parecem que certos elementos ou resquícios de fatos históricos anteriores ou passados se evidenciam em outras épocas e contextos. Não que sejam os mesmos sistemas, nem tampouco a continuidade deles, mas apenas semelhanças e características que parecem ‘ir e vir. ’ Diante de tais fatos, seus problemas e consequências; debruçamo-nos em fontes sobre o Sistema Feudal Europeu dos séc. X ao XIV d. C. para compreendermos elementos, eventos e episódios que vêm ocorrendo na contemporaneidade brasileira, com algumas semelhanças com o Sistema Feudal.

Resumo: Um dos grandes problemas das ciências em geral, é a constante busca por universalizações, generalizações e sistematizações dos seus objetos, dados, conteúdos e resultados. Talvez sejam ainda vestígios ou resquícios do positivismo ou a identificação com um possível cientificismo. Porém, ao se fazer isso, nega-se o próprio caráter, o papel, o sentido e a função da ciência, que é ser provisória, e não permanente ou eterna. Mesmo havendo em certos casos, a possibilidade de universalizações, generalizações e sistematizações, no qual (...) também ainda permanecerão abertas e não fechadas em si. Logo, neste trabalho se procura debruçar e refletir sobre o que é história, o sentido da história e a historiografia por abordagens, aspectos e instrumentos da filosofia, da sociologia, da antropologia, da filosofia da história, da historiografia, da teoria da história, da escrita da história e dentre outros. Isso para que deste modo talvez possamos nos desvencilhar de certos mitos, conteúdos e produções de certa história e historiografia universalista. Uma vez que, em tal narrativa e escrita da história, produziram-se muitas interpretações equivocadas, míticas e generalizantes da história do mundo e dos povos em geral, onde, de modo arbitrário, o eurocentrismo, o europeísmo e o ocidentalismo assumiram a apresentação e representação da produção histórica e cultural do mundo, quase uma aculturação e homogeneização dos povos, culturas e etnias, descaracterizando-os nas suas próprias narrativas e processos históricos, isso dentro de um “pacote e produto histórico ocidental”. No qual a história foi colocada e reduzida a determinismos de diversos tipos e modos. Logo, um dos objetivos cruciais aqui, é justamente desconstruir tais narrativas, percepções e procedimentos de sorrateira aculturação e etnocentrismo da história mundial. Portanto, é necessário superar toda e qualquer narrativa, escrita e produção histórica que coloca grupos, etnias e culturas entre superiores e inferiores na produção histórica e na história, no qual os grupos superiores fazem a história e são os protagonistas dela, enquanto os grupos inferiores são os meros coadjuvantes no mundo, bem como na produção histórica. Isso ocorre porque a história e a produção da mesma são campos de disputas, conflitos e embates de ideais, mesmo pela produção científica. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

Este trabalho tem como objetivo verificar como educandos da Rede Pública de ensino do Município de Niterói/RJ percebem o fenômeno da violência nas suas comunidades e como esta percepção se evidencia em seus discursos. Para isso foi aplicado um questionário semiestruturado com questões objetivas e uma discursiva, no qual foi respondido por 120 estudantes com idades entre 13 e 17 anos da Rede Estadual de Ensino de escolas da Zona Norte de Niterói, estado do Rio de Janeiro. As respostas às (...) questões objetivas foram analisadas quantitativamente e à questão discursiva por meio de técnica categorial, onde as categorias eram os itens escolhidos nas respostas dos estudantes. As questões discursivas foram analisadas qualitativamente, gerando uma análise quanti-qualitativa. Verificamos também resultados de pesquisas análogas, e a discussão foi construída à luz dos teóricos Albert Bandura, Michel Foucault e Lev Vygotsky, no qual se mostrou que nossos dados são suportados pela literatura.

This paper reviews the central points and presents some recent developments of the epistemic approach to paraconsistency in terms of the preservation of evidence. Two formal systems are surveyed, the basic logic of evidence (BLE) and the logic of evidence and truth (LET J ), designed to deal, respectively, with evidence and with evidence and truth. While BLE is equivalent to Nelson’s logic N4, it has been conceived for a different purpose. Adequate valuation semantics that provide decidability are given for (...) both BLE and LET J . The meanings of the connectives of BLE and LET J , from the point of view of preservation of evidence, is explained with the aid of an inferential semantics. A formalization of the notion of evidence for BLE as proposed by M. Fitting is also reviewed here. As a novel result, the paper shows that LET J is semantically characterized through the so-called Fidel structures. Some opportunities for further research are also discussed. (shrink)

Diante dos embates e dilemas que vive o Brasil após o ano de 2016, fundamentalmente no que diz respeito a educação pública brasileira, o presente trabalho procurou se debruçar, refletir e verificar a posição e situação do educando brasileiro no cenário social nacional, e sobretudo escolar. Levamos em conta como base de configuração do indivíduo-sujeito e estudante sua identidade enquanto ser biopsicossocial, isso na perspectiva Aristotélica e Marxista de homem, tanto como ser dotado de razão, emoção, vontade, social, político, teleológico (...) (Aristóteles) e essencialmente ser de trabalho e histórico (Marx). (shrink)

In 2016, Béziau introduces a restricted notion of paraconsistency, the so-called genuine paraconsistency. A logic is genuine paraconsistent if it rejects the laws $\varphi,\neg \varphi \vdash \psi$ and $\vdash \neg (\varphi \wedge \neg \varphi)$. In that paper, the author analyzes, among the three-valued logics, which of them satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above-mentioned are $\vdash \varphi, \neg \varphi$ and $\neg (\varphi \vee \neg \varphi) \vdash$. We call genuine paracomplete logics those rejecting (...) the mentioned properties. We present here an analysis of the three-valued genuine paracomplete logics. A very natural twist structures semantics for these logics is also found in a systematic way. This semantics produces automatically a simple and elegant Hilbert-style characterization for all these logics. Finally, we introduce the logic LGP which is genuine paracomplete is not genuine paraconsistent, not even paraconsistent and cannot be characterized by a single finite logical matrix. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

O presente trabalho em tela busca se debruçar nas relações e interconexões entre etnocentrismo, xenofobia e medo. Entretanto, o medo é medo de alguma coisa ou de alguém. Talvez do nada. Porém, quando nos deparamos com o medo, pensamentos e práticas etnocêntricas e xenofóbicas, a literatura demonstra que há processos ligados a mecanismos de pulsão, repressão e recalque, pois o medo está como pano de fundo, causando um desencadeamento de emoções e sentimentos de um sujeito frente ao outro. Então, quando (...) dois indivíduos se encontram, há um conflito interno por questões culturais e de objetificação entre ambos. Desse modo, o conflito não é apenas pessoal ou individual, mas fundado em estruturas e formação cultural. Portanto, quando dois indivíduos distintos se encontram, também são duas culturas se defrontando. Com isso, podem ocorrer pensamentos e práticas etnocêntricas e xenofóbicas oriundas do medo, de se estar diante do outro, do diferente, do desconhecido e que não sou eu. Assim, com o medo colocado, aparece o conflito, a angústia, o repúdio e a negação do outro. E daí já se evidencia o etnocentrismo e a xenofobia. Porém, o impulso é o recalque que se reprime por medo do outro, do diferente e do desconhecido. Logo, Etnocentrismo, Xenofobia e Medo: Pulsão, Repressão e Recalque como Medo oculto do outro, do desconhecido, do diferente e do diverso, talvez tal fato só apaziguemos com um olhar com análises relativizadoras, tanto das culturas como dos outros, pois talvez assim se possa encontrar a saída de tais neuroses. A pesquisa adentra pelas teorias da Antropologia e com suportes de campos da Psicologia, História, Psicanálises e Sociologia. Desse modo, a pesquisa não abarca apenas o caráter bibliográfico e de revisão da literatura, mas também adentra sutilmente pelos caminhos da “observação e descrição” do fato e fenômeno histórico-social, fazendo assim certo esforço de “explorá-lo e explicá-lo” pelas teorias de base, que suportam o construto.
