In this paper, first, we determine the number of sublogics of variable inclusion of an arbitrary finitary logic ⊢ with a composition term. Then, we investigate their position into the lattice of co...

The paper studies the containment companion of a logic \. This consists of the consequence relation \ which satisfies all the inferences of \, where the variables of the conclusion are contained into those of the set of premises, in case this is not inconsistent. In accordance with the work started in [10], we show that a different generalization of the Płonka sum construction, adapted from algebras to logical matrices, allows to provide a matrix-based semantics for containment logics. In particular, (...) we provide an appropriate completeness theorem for a wide family of containment logics, and we show how to produce a complete Hilbert style axiomatization. (shrink)

The logic DAI of demodalised analytic implication has been introduced by J.M. Dunn as a variation on a time-honoured logical system by C.I. Lewis’ student W.T. Parry. The main tenet underlying this logic is that no implication can be valid unless its consequent is “analytically contained” in its antecedent. DAI has been investigated both proof-theoretically and model-theoretically, but no study so far has focussed on DAI from the viewpoint of abstract algebraic logic. We provide several different algebraic semantics for DAI, (...) showing their equivalence with the known semantics by Dunn and Epstein. We also show that DAI is algebraisable and we identify its equivalent quasivariety semantics. This class turns out to be a linguistic and axiomatic expansion of involutive bisemilattices, a subquasivariety of which forms the algebraic counterpart of Paraconsistent Weak Kleene logic. This fact sheds further light on the relationship between containment logics and logics of nonsense. (shrink)

O objetivo do artigo é analisar o conceito de liberdade presente na obra de Rousseau e fornecer argumentos para questionar a imagem do homem natural como um ser livre, de modo a sustentar a tese de que a liberdade somente se torna possível com a saída do estado de natureza descrito no Discurso sobre as origens da desigualdade . Assim, o autor pretende mostrar que o surgimento da consciência e da racionalidade é indispensável para que o homem consiga desenvolver suas (...) faculdades virtuais e seja capaz de criar para si padrões de comportamento diferentes do instinto natural, um processo que ocorre graças à vida em sociedade.

O objetivo deste trabalho é duplo: primeiramente, tecer alguns comentários sobre o uso feito pelo filósofo da ocorrência de fenômenos da natureza como fatores explicativos para mudanças profundas ocorridas no comportamento humano, um recurso argumentativo presente nas duas narrativas hipotéticas; em seguida, abordar as razões que Rousseau fornece para que esses acontecimentos deixem de ser simples fatos naturais e se tornem verdadeiras catástrofes para o ser humano, as quais podem ser encontradas, por exemplo, na Carta a Voltaire sobre a Providência.

Paraconsistent Weak Kleene Logic is the 3-valued propositional logic defined on the weak Kleene tables and with two designated values. Most of the existing proof systems for PWK are characterised by the presence of linguistic restrictions on some of their rules. This feature can be seen as a shortcoming. We provide a cut-free calculus for PWK that is devoid of such provisos. Moreover, we introduce a Priest-style tableaux calculus for PWK.

Uma concepção de cosmopolitismo, de base eurocêntrica, é questionada por pensadores como K. A. Appiah, Walter Mignolo, Silviano Santiago entre outros, para buscar possíveis ressemantizações do termo no contexto contemporâneo, marcado pela globalização, pelo multiculturalismo e pela expansão das novas tecnologias de comunicação. Considerando esse confronto de noções de cosmopolitismo, indaga-se como se deu a interpretação do Brasil no início do século XX, quando recrudesceram as tensões entre cosmopolitismo e nacionalismo. Busca-se, por outro lado, confrontar tais interpretações com as que (...) surgem no início do século XXI, quando a nação vai deixando de ser o centro de um sistema de significação, em tempo heterogêneo e de globalização, em que se pode falar em “cosmopolitismo do pobre” (cosmopolitismo do subalterno), como formulou Silviano Santiago.

The Oxford University Studies in the Enlightenment series, previously known as SVEC (Studies on Voltaire and the Eighteenth Century), has published over 500 peer-reviewed scholarly volumes since 1955 as part of the Voltaire Foundation at the University of Oxford. International in focus, Oxford University Studies in the Enlightenment volumes cover wide-ranging aspects of the eighteenth century and the Enlightenment, from gender studies to political theory, and from economics to visual arts and music, and are published in English or French.

The article examines Kant's notion of conceptual extension in order to determine a conception of predication that could integrate, in a coherent fashion, basic theoretical commitments of general logic as he conceived it and the central tenets of his transcendental logic. After a brief overview of the several characterizations of thatnotion in the Kantian corpus, I distinguish three interpretative models concerning it in the literature. Such models are criticized and their prospects of integrating Kant's commitments in a fully satisfactory way (...) are rejected. Finally, I sketch an alternative account of Kant's notion of conceptual extension, which respects the criteria of adequacy that guided the examination of the former models. It points, on its turn, to a revaluation of Kant's notion of conceptual content. (shrink)

The discussion on ethical issues, it is said, should not be confined to experts but should be extended to patients and local communities, because of the real need to engage stakeholders and non‐stakeholders alike not only in carrying out any biomedical research project, but also in the drafting and legislation of bioethics instruments. Several local and inter‐country consultations have already been conducted in furtherance of this goal, but there is much left to be desired in them. The consultations may have (...) helped in articulating local principles, but not in making the instruments embody these principles. As such, instruments turn incompossible, i.e. the principles and actions they legitimate are not performable. In an ethnographic study conducted in the Philippines, for example, paragraphs 29 and 30 of the Declaration of Helsinki and CIOMS guidelines 8 and 15 are construed as not only contradictory to one another but also to local principles. This problem can be solved by taking deliberate steps to ensure that consultations are grounded in ethnographic data about local principles, which the instruments would embody. A steering committee can be of help in gathering ethnographic data, in conducting consultations at the local level, and in providing a venue for discourse on various bioethical issues. (shrink)

In this paper, I defend that the historiographical category of eclecticism is a correct way to describe the epistemology and the exegetical activity of the Anonymous commentator on Plato’s Theaetetus. In addition, I show that the interpretation of the platonic philosophy presented in this text not only presupposes an eclectic philosophical attitude, but also offers a conscious defense of a positive and philosophically relevant form of eclecticism. By eclecticism, I understand a method of inquiry based on the deliberate use of (...) hypotheses and arguments from different philosophical traditions. My claim is that Anon. intends to lay ground of his way of doing philosophy by attributing it to Plato and the platonic tradition. In doing so, Anon. provides us with a positive understanding of eclecticism as a legitimate methodology of philosophical investigation. (shrink)

Para Freud, a disciplina que criou fazia indiscutivelmente parte das ciências da Natureza, e de modo algum daquelas 'do espírito', como então se chamavam na Alemanha as atuais ciências humanas. Para nós, contemporâneos, tal asserção parece muito estranha: que objeto poderia ser mais humano do que o espírito humano, tema da Psicanálise? Este artigo retoma esse problema pelo ângulo da partição entre os dois tipos de ciência que vigoravam no tempo e no ambiente cultural de Freud, no interior da qual (...) faz sentido a sua enfática afirmação. Mostra que já não dividimos o campo do saber da mesma maneira que então, o que torna possível alojar a Psicanálise ao lado de disciplinas como a História, a Etnologia e outras do mesmo gênero, portanto, no campo das ciências humanas. A parte final do texto explora alguns intrigantes paralelismos epistemológicos entre as noções de 'seleção natural' e 'inconsciente', e as estratégias retóricas de que Darwin e Freud - este, aparentemente sem se dar conta de que estava imitando seu grande predecessor - se utilizam para criar no leitor a convicção de que são indispensáveis para estruturar o campo das respectivas disciplinas.Freud had never any doubts that his invention belonged in the field of natural science, and not in the area of the 'sciences of the Spirit', as human/social sciences were then called in Germany. For us, this sounds strange: what could be more human than human mind, the subject of Psychoanalysis? This paper argues that the way of separating both fields in which Freud's claim makes sense has changed considerably since his day, so that we are justified in ranking Psychoanalysis on the same side as History, Anthropology and similar disciplines, as we usually do nowadays. It also explores some intriguing parallels between the notions of 'natural selection' and 'unconscious', as well as some rhetorical strategies employed by both Darwin and Freud - in this case, probably unaware that he was copying his great predecessor - when they set to the task of persuading their readers that those ideas cannot be dispensed with in their respective fields.

The coastal area of Bangladesh is one of the most ecologically productive and it contains a rich biodiversity which includes several species that are endemic to this region. Much attention has been focused on ship breaking industries in the coastal areas because of the threat they pose to this thriving biological communities along with their other environmental impacts and the perilous working environment of the workers. The coastal environment of Sitakunda is severely contaminated by various processes related to ship-breaking i.e. (...) the disposal of different toxic wastes into the sea water, deforestation by expanding ship breaking yard, changing land-use pattern and release of toxic substance into the soil. Moreover, the workers of this industry are exposed to an extremely risky and toxic working environment which makes them vulnerable to both physical and psychological disorder as well as to accidental deaths and injury. Still, workers embrace these risks for very poor wages and most of the profits go to the already rich businessmen. Despite various negativities, this industry has gained importance due to the increasing demand of raw material for re-rolling industries and employment opportunities for the people of the coastal areas. As this industry is indispensable due to its importance in the macro and micro economy of Bangladesh, a sustainable management approach should be taken to at least minimize the environmental and health impacts of ship breaking industries. The current paper aims to investigate the extent to which this industry is affecting the ship breaking yard labors and the environment, despite the growing concern nationally and internationally, and it uses both primary and secondary data.
