1. ON A NEW APPROACH TO PEIRCE’S THREE-VALUE PROPOSITIONAL LOGIC
Abstract In 1909, Peirce recorded in a few pages of his logic notebook some experiments with matrices for three-valued propositional logic. These notes are today recognized as one of the first attempts to create non-classical formal systems. However, besides the articles published by Turquette in the 1970s and 1980s, very little progress has been made toward

2. A Simplest Method to Enhance the Benefits of Internal Thoracic Artery Distal Occlusion
Abstract A common element of internal thoracic artery harvesting techniques is a distal vascular clamp placement at the end of the procedure, not only to avoid bleeding, but also to increase the internal hydrostatic pressure, diameter and flow. The logic indicates that the placement of this clamp at the beginning of the dissection will allow the artery to be

3. Le corps d’adolescent au Rorschach
Com base em quadro teórico inscrito nas teorias da relação de objeto, nos processos de transformação e de coconstrução, a autora tem por intenção observar e descrever os processos de transformação. Os novos organizadores psíquicos “techne” e “campo” inscritos em uma relação do tipo continente-conteúdo permitem a compreensão das transf

4. Acumulação fictícia, especulação e instabilidade financeira. Parte I: uma reflexão sobre a financeirização a partir de Marx, Keynes e Minsky*
Resumo Este texto, tem como objetivo essencial, entender os principais traços da financeirização, à luz da contribuição de autores clássicos como Marx, Keynes e Minsky, dos quais se enfatiza algumas categorias analíticas, distintas, mas similares. Ao fazer isto, busca investigar como esses autores estabeleceram os fundamentos para o tratamento do tem

5. Razão e Administração: revisitando alguns elementos fundamentais
Resumo As ações e os processos administrativos parecem estar em um período pós-racional, no qual a racionalidade se tornou uma palavra mal compreendida, sendo a ação racional comumente associada ao cientificismo e à tecnocracia. Acreditamos que esse estereótipo pode ter um fundo de verdade, mas é, sobretudo, baseado em um mal-entendido fundamental q

6. TOWARDS A PHILOSOPHICAL UNDERSTANDING OF THE LOGICS OF FORMAL INCONSISTENCY
Abstract In this paper we present a philosophical motivation for the logics of formal inconsistency , a family of paraconsistent logics whose distinctive feature is that of having resources for expressing the notion of consistency within the object language in such a way that consistency may be logically independent of non-contradiction. We defend the view a

7. TRABALHADORES ARGENTINOS: respostas e propostas frente a ofensiva neoliberal
The objective of this work is to examine some experiences of Argentine workers who never yielded to the advance of neoliberalism in the 1990s, but who, instead, organized themselves and managed to resist and, in some cases, reverse the political offensive of that decade. We refer to three key experiences to understand this historical process. Firstly, the or

8. THE LOGICAL SYSTEM OF FREGE'S GRUNDGESTZE: A RATIONAL RECONSTRUCTION
This paper aims at clarifying the nature of Frege's system of logic, as presented in the first volume of the Grundgesetze . We undertake a rational reconstruction of this system, by distinguishing its propositional and predicate fragments. This allows us to emphasise the differences and similarities between this system and a modern system of classical second

9. A persistência do Paradoxo da Cognoscibilidade / The persistence of Knowability Paradox
Esta dissertação tem como objetivo a análise de um resultado em lógica aléticoepistêmica, divulgado por Frederic Fitch em 1963, conhecido como Paradoxo da Cognoscibilidade. Segundo este resultado, se todas verdades podem ser conhecidas, então todas verdades são conhecidas. Isto sugere que há alguma verdade impossível de ser conhecida. Descrevemos,

10. Matrix- based logic for avoiding paradoxes and its paraconsistent alternative
The present article shows that there are consistent and decidable many- valued systems of propositional logic which satisfy two or all the three criteria for non- trivial inconsistent theories by da Costa (1974). The weaker one of these paraconsistent system is also able to avoid a series of paradoxes which come up when classical logic is applied to empirica

11. Da Costa on ontology: a naturalistic interpretation
Da Costa's conception of being modifies that of Quine to incorporate relativization to non-classical logics. A naturalistic view of this conception is discussed. This view tries to extend to logic some ideas of Maddy's naturalism concerning mathematics.

12. The role of consistency in empirical science
Any inconsistent theory whose underlying logic is classical encompasses all the sentences of its own language. As it denies everything it asserts, it is useless for explaining or predicting anything. Nevertheless, paraconsistent logic has shown that it is possible to live with contradictions and still avoid the collapse of the theory. The main point of this
