O tema é discricionariedade nas teorias do positivismo antes e depois de Dworkin desde a crítica hermenêutica do direito e sua teoria da decisão. O problema é: há a possibilidade de uma teoria da decisão no positivismo, seja ele qual for, mantendo-se intactos os seus princípios metodológicos da descrição e da separação entre direito e moral? O objetivo é apresentar a crítica hermenêutica do direito e sua oposição à discricionariedade dos positivismos. A conclusão é a de que a crítica hermenêutica (...) não é apenas negativa com relação aos positivismos, ela é também positiva e construtiva de uma teoria da decisão. (shrink)

Resumo A proposta deste artigo é apresentar parte do processo de formação do MOBON (Movimento da Boa Nova) e as idéias que o nortearam na década de 1980, bem como a influência do trabalho de mediação realizado por ele na Zona da Mata mineira. Este movimento se mostrou importante para a expressiva votação de candidatos do Partido dos Trabalhadores (PT) naquela região. Tal fato chamou a atenção da imprensa nacional em função do trabalho de mediação religiosa na conformação da posição (...) política daqueles grupos. A candidatura de Lula não obteve apoio da população em muitos espaços onde os bispos o apoiavam abertamente. Nosso argumento centra-se na idéia de que as características locais e o cotidiano são mais fundamentais na formação das idéias e concepções de mundo dos atores sociais que o apoio de lideranças da alta cúpula eclesiástica, que pode ser vista como distante da população, ao contrário da organização popular que é feita no cotidiano político. Assim, vamos apresentar reflexões a respeito do trabalho missionário e a forma como este acabou se constituindo e obtendo repercussão política. Palavras-chave: Religião; Imprensa; Política .The proposal of this paper is to present part of the MOBON (“Boa Nova” Movement) formation process, its ideas in the 1980s, as well as the influence of its mediation work in the Forest Zone of Minas Gerais state. This movement showed to be important due to the expressive number of votes in the Worker’s Party (PT) in that region. This fact caught the attention of the national media regarding the religious mediation work in the conformation of these groups’ political positions. The Lula candidacy did not have the population support in many spaces where the bishops supported him openly. Our thesis focus the idea that the local characteristics and the everyday life are more fundamental in the social actors formation of ideas and world standpoints than the support of a bishop that can be seen as distant by the population, what does not happen in the popular organization which is performed in the everyday politics. Therefore, we will present comments on the missionary work and the way it is building and obtaining political repercussion. Key-words: Religion; Press; Politics. (shrink)

BackgroundThe impact of a cancer diagnosis may be traumatic, depending on the psychological resources used by patients. Appropriate coping strategies are related to better adaptation to the disease, with coping flexibility, corresponding to the ability to replace ineffective coping strategies, demonstrated to be highly related with self-efficacy to handle trauma. The Perceived Ability to Cope with Trauma scale is a self-rated questionnaire that assesses the perceived ability to cope with potentially traumatic events, providing a measure of coping flexibility. The current (...) study aimed at examining the psychometric properties of the PACT Scale in Portuguese patients with breast cancer.MethodsThe study included 172 patients recently diagnosed with early breast cancer. Participants completed a Portuguese version of the PACT scale, and instruments of self-efficacy for coping with cancer, of quality of life, and of psychological distress that were used as convergent and divergent measures, thus assessing construct validity. A confirmatory factor analysis was performed to test the factor structure of the Portuguese version of PACT scale and reliabilities were examined.ResultsResults from the CFA confirmed the two-factor structure, consistent with the original Forward and Trauma focus subscales. The two subscales demonstrated high internal consistencies. Convergent and divergent validities were confirmed: the PACT scale was related to high self-efficacy to cope with cancer, to high perceived quality of life, and to low psychological distress.DiscussionOverall, the current results support and replicate the psychometric properties of the PACT scale. The scale was found to be a valid and reliable self-reported measure to assess Portuguese breast cancer patients regarding beliefs about their capabilities in managing the potentially traumatic sequelae of cancer. The PACT is a simple and brief measure of coping flexibility to trauma, with potential relevance for application in clinical and research settings. (shrink)

Da Costa and French explore the consequences of adopting a 'pragmatic' notion of truth in the philosophy of science. Their framework sheds new light on issues to do with belief, theory acceptance, and the realism-antirealism debate, as well as the nature of scientific models and their heuristic development.

The mathematical concept of pragmatic truth, first introduced in Mikenberg, da Costa and Chuaqui (1986), has received in the last few years several applications in logic and the philosophy of science. In this paper, we study the logic of pragmatic truth, and show that there are important connections between this logic, modal logic and, in particular, Jaskowski's discussive logic. In order to do so, two systems are put forward so that the notions of pragmatic validity and pragmatic truth can (...) be accommodated. One of the main results of this paper is that the logic of pragmatic truth is paraconsistent. The philosophical import of this result, which justifies the application of pragmatic truth to inconsistent settings, is also discussed. (shrink)

An introduction to the model-theoretic approach in the philosophy of science is given and it is argued that this program is further enhanced by the introduction of partial structures. It is then shown that this leads to a natural and intuitive account of both "iconic" and mathematical models and of the role of the former in science itself.

Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by ‘superposition’ in each case is extremely different. In this paper we discuss some of the multiple interpretations which exist in the literature regarding superpositions in quantum mechanics. We argue that all these interpretations have something in common: they all attempt to avoid ‘contradiction’. We argue in this paper, in favor of the importance of developing a new interpretation of superpositions which takes into account contradiction, (...) as a key element of the formal structure of the theory, “right from the start”. In order to show the feasibility of our interpretational project we present an outline of a paraconsistent approach to quantum superpositions which attempts to account for the contradictory properties present in general within quantum superpositions. This approach must not be understood as a closed formal and conceptual scheme but rather as a first step towards a different type of understanding regarding quantum superpositions. (shrink)

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of the theory and (...) to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate. (shrink)

The purpose of the present paper is to consider the traditional interpretive problems of quantum mechanics from the viewpoint of a modal ontology of properties. In particular, we will try to delineate a quantum ontology that (i) is modal, because describes the structure of the realm of possibility, and (ii) lacks the ontological category of individual. The final goal is to supply an adequate account of quantum non-individuality on the basis of this ontology.

Problems of logical theory choice are current being widely dis- cussed in the context of anti-exceptionalist views on logic. According to those views, logic is not a special science among others, so, in particular, the methodology for theory choice should be the same in logic as for other scientific disciplines. Richard Routley advanced one such methodology which meshes well with anti-exceptionalism, and argued that it leads one to choosing one single logic, which is a kind of ultralogic. We argue that (...) the choice for only one correct system of logic may be rejected on the basis of the methodology proposed by Routley and, furthermore, that taking anti-exceptionalism about logic seriously recommends that a pluralist view of logic should be accepted. We call this view “full-blooded anti-exceptionalism”, and the resulting view on logic, lacking a proper name, “local pluralism”. (shrink)

This paper seeks to provide an approach for achieving a more socially and environmentally sustainable life by reframing the rules of engagement with the planet and with each other by setting minimum standards on essential criteria i.e., by defining “off-limits”zones for corporate action. For a more humanistic and socially just way of living life that would sustain the planet, a set of moral boundaries that cannot be breached are conceived. We offer a set of possible normative leverage points that must (...) not be violated by business in the long-term. Our paper takes a forward-looking view beyond the current generational targets for sustainability. We operate on the premise that sustainability involves preserving the future generations of the planet in both an environmental and human sense. The Moral Boundaries for Business framework embraces the Seventh Generation Principle. The moral boundaries we offer in this paper, if followed, are meant to have positive implications for humanity and the planet in the next seven generations. (shrink)

The apparently paradoxical nature of self-deception has attracted a great deal of controversy in recent years. Focussing on those aspects of the phenomenon which involve the holding of "contradictory" beliefs, it is our intention to argue that this presents no "paradox" if a non-classical, "paraconsistent", doxastic logic is adopted. (On such logics, see, for example, N. C. A. da Costa, 'On the theory of inconsistent formal systems', Notre Dame J Formal Logic 11(1974), 497-510, and A. I. Arruda, 'A survey (...) of paraconsistent logic', in A. I. Arruda, N. C. A da Costa and R Chuaqui, _Mathematical Logic in Latin America, North-Holland, 1984, pp. 1-41.). (shrink)

We expose the main ideas, concepts and results about Jaśkowski's discussive logic, and apply that logic to the concept of pragmatic truth and to the Dalla Chiara-di Francia view of the foundations of physics.

Body awareness refers to the individual ability to process signals originating from within the body, which provide a mapping of the body’s internal landscape and its relation with space and movement. The present study aims to evaluate psychometric properties and validate in French two self-report measures of body awareness: the Postural Awareness Scale, and the last version of the Multidimensional Assessment of Interoceptive Awareness questionnaire. We collected data in a non-clinical, adult sample using online survey, and a subset of the (...) original sample also completed the retest control. Factor analyses and reliability analyses were conducted. Construct validity of the PAS and the MAIA-2 were examined by testing their association with each other, and with self-report measures of personality, alexithymia and dispositional trait mindfulness. Factor analyses of the PAS supported the same two-factor structure as previously published versions. For the MAIA-2, factor analyses suggested that a six-factor structure, excluding Not-Worrying and Not-Distracting factors, could successfully account for a common general factor of self-reported interoception. We found satisfactory internal consistency, construct validity, and reliability over time for both the PAS and the MAIA-2. Altogether, our findings suggest that the French version of the PAS and the MAIA-2 are reliable self-report tools to assess both components of body awareness. (shrink)

Abstract A general framework is proposed for accommodating the recent results of studies into ?natural? decision making. A crucial element of this framework is the notion of a ?partial structure?, recently introduced into the semantic approach to scientific theories. It is through the introduction of this element that connections can be made with certain problems regarding inconsistency and rationality in general.

We apply the recently elaborated notions of 'pragmatic truth' and 'pragmatic probability' to the problem of the construction of a logic of inductive inference. It is argued that the system outlined here is able to overcome many of the objections usually levelled against such attempts. We claim, furthermore, that our view captures the essentially cumulative nature of science and allows us to explain why it is indeed reasonable to accept and believe in the conclusions reached by inductive inference.

We investigate the higher-order modal logic , which is a variant of the system presented in our previous work. A semantics for that system, founded on the theory of quasi sets, is outlined. We show how such a semantics, motivated by the very intuitive base of Schrödinger logics, provides an alternative way to formalize some intensional concepts and features which have been used in recent discussions on the logical foundations of quantum mechanics; for example, that some terms like 'electron' have (...) no precise reference and that 'identical' particles cannot be named unambiguously. In the last section, we sketch a classical semantics for quasi set theory. (shrink)

Although from a philosophical perspective, many reflections can be brought up about the theorizing process, in this essay, we aim to reflect on the importance of the alignment between ontology and epistemology. This is particularly relevant because deeper discussions about the philosophical roots that underlay the theorizing processes remain as a lack in organizational and management studies. To support our work, we adopted the epistemic-ontological alignment model as a conceptual tool and the Resource-Based View (RBV) and some of its questionings (...) as an example to carry out a reflection exercise about its epistemic-ontological alignment. RBV is a theory that plays a prominent role in management studies, especially in the strategy field. Nevertheless, discussions regarding RBV philosophical foundations are not common in the mainstream of strategic management. After our analysis, we advise that scholars care about the philosophical roots of their theoretical proposals to promote constructive dialogue in their research communities. This can avoid empty discussions and criticisms based on incongruous worldviews. Our reflections also suggest that future research should embrace the plurality of paradigms as a source of renewal and transcendence in the production of knowledge. A multi-paradigmatic movement towards more eclecticism in Administrative Science can help produce new and underexploited combinations of knowledge in the theorizing process. (shrink)

We discuss the hypothesis that the debate about the interpretation of the orthodox formalism of quantum mechanics might have been misguided right from the start by a biased metaphysical interpretation of the formalism and its inner mathematical relations. In particular, we focus on the orthodox interpretation of the congruence relation, '=', which relates equivalent classes of different mathematical representations of a vector in Hilbert space, in terms of metaphysical identity. We will argue that this seemingly "common sense" interpretation, at the (...) semantic level, has severe difficulties when considering the syntactic level of the theory. (shrink)

In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of (...) Miró Quesada’s theory of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J. C. Cifuentes and L. F. Bartolo Alegre.

The issue of what consequences to draw from the existence of non-classical logical systems has been the subject of an interesting debate across a diversity of fields. In this paper the matter of alternative logics is considered with reference to a specific belief system and its propositions :the Azande are said to maintain beliefs about witchcraft which, when expressed propositionally, appear to be inconsistent. When the Azande have been presented with such inconsistencies, they either fail to see them as such (...) or else accept them as non-problematical. Is our knowledge of logical truths a relative and culturally determined phenomenon, or is there some (transcendent) criterion that allows us to adjudicate between alternative logical systems? The authors propose an approach for resolving disputes about the status of Azande reasoning which assumes a paraconsistent framework, thus providing a new perspective on this debate. (shrink)

No presente trabalho apresentamos e traduzimos o texto “O Perigo da confirmação não-empírica", de Carlo Rovelli, cosmólogo italiano, um dos proponentes da gravitação quântica em loop. Trata-se do texto apresentado por Rovelli em 2015 durante o chamado “Debate de Munich” sobre o problema da base empírica do método científico. Rovelli analisa – e se contrapõe – à proposta do filósofo da ciência Richard Dawid, que em String Theory and the Scientific Method, defende que teorias científicas podem ser avaliadas, aceitas e (...) defendidas a partir de critérios não-empíricos. Rovelli, a despeito de concordar com Dawid quanto a importância histórica dos argumentos não-empíricos no desenvolvimento de teorias físicas, sustenta que a confirmação empírica deve permanecer sendo considerada indispensável para a prática científica e o sucesso cumulativo da ciência.

Este artigo busca refletir sobre condições iniciais da sociedade pré- humana explicando como dois fenômenos biológicos – adaptativos, a bipedalização e neotenia, ajudaram a emergir no homem características próprias humanas tais como a solidariedade. Procura também lançar critica se a Teoria da Evolução pode ou não explicar comportamentos humanos complexos.

We use Padoa's principle of independence of primitive symbols in axiomatic systems in order to show that time is dispensable in continuum thermodynamics, according to the axiomatic formulation of Gurtin and Williams. We also show how to define time by means of the remaining primitive concepts of Gurtin and Williams system. Finally, we introduce thermodynamics without time as a primitive concept.

On the one hand, non-reflexive logics are logics in which the principle of identity does not hold in general. On the other hand, quantum mechanics has difficulties regarding the interpretation of ‘particles’ and their identity, also known in the literature as ‘the problem of indistinguishable particles’. In this article, we will argue that non-reflexive logics can be a useful tool to account for such quantum indistinguishability. In particular, we will provide a particular non-reflexive logic that can help us to analyze (...) and discuss this problem. From a more general physical perspective, we will also analyze the limits imposed by the orthodox quantum formalism to consider the existence of indistinguishable particles in the first place, and argue that non-reflexive logics can also help us to think beyond the limits of classical identity.

Este artigo dialoga com autores que estudam a temática juventude e escola, problematizando a função da escola como locus de socialização. Parte do pressuposto de que muitos problemas enfrentados pelos jovens na escola é resultado de uma realidade em que as culturas juvenis, caracterizadas por determinadas formas de comportamento, como, gostos, atitudes, estilo de vida, forma de ser, vestir, dançar, falar, se divertir e se relacionar não podem se fazer presentes. Em virtude disso, analisa a desarticulação da escola com as (...) perspectivas dos jovens, ao acharem-na desinteressante por não contemplar seus anseios e suas necessidades e tampouco reconhecer a realidade em que estão inseridos. Parte da concepção de que a escola deve contemplar espaços e situações que promovam experiências de sociabilidade. Busca uma reflexão acerca do papel da escola diante das tensões e dos dilemas juvenis. (shrink)

Toma-se a crítica de Nietzsche a Sócrates como um caso exemplar que mostra os dois sentidos fundamentais da crítica nietzscheana: a crítica nietzscheana consiste em censura e em elogio de modo dual, ou seja, censura e elogio são aspectos da crítica; e ao criticar alguém, Nietzsche está, igualmente, se autocriticando.

Tocqueville e John Stuart Mill são dois dos grandes mestres de ciência política e filosofia política. Com efeito, poderíamos dizer que somos todos discípulos destes autores. Por um lado, porque Tocqueville foi o primeiro autor a refletir sobre o paradigma democrático, entendido como constelação política especificamente moderna. Por outro lado, o conceito ou ideal de liberdade desempenha um papel central nos dois autores. Liberdade é um dos pilares fundadores de qualquer projeto democrático e apesar do reconhecimento da importância igualmente vital (...) do conceito de igualdade, que se vem afirmando como condição necessária para o desenvolvimento politico na era de Tocqueville e de Mill, a liberdade permanece central nas suas preocupações. Neste artigo irei revisitar os argumentos avançados pelos autores, argumentos estes que nos alertam para os perigos da democracia, e mais precisamente, a tirania da maioria. Começarei por retratar o contexto das obras de Democracia na América de Tocqueville e Sobre a Liberdade de Mill. De seguida, ofereço uma reflexão sobre as implicações da tirania da maioria hoje. Por fim, proponho um conjunto de medidas que nos poderão ajudar a contrabalançar as tendências antidemocráticas das democracias contemporâneas. (shrink)

Quasi-set theory is a theory for dealing with collections of indistinguishable objects. In this paper we discuss some logical and philosophical questions involved with such a theory. The analysis of these questions enable us to provide the first grounds of a possible new view of physical reality, founded on an ontology of non-individuals, to which quasi-set theory may constitute the logical basis.

It is usually stated that quantum mechanics presents problems with the identity of particles, the most radical position—supported by E. Schrödinger—asserting that elementary particles are not individuals. But the subject goes deeper, and it is even possible to obtain states with an undefined particle number. In this work we present a set theoretical framework for the description of undefined particle number states in quantum mechanics which provides a precise logical meaning for this notion. This construction goes in the line of (...) solving a problem posed by Y. Manin, namely, to incorporate quantum mechanical notions at the foundations of mathematics. We also show that our system is capable of representing quantum superpositions. (shrink)
