The authors of Beziau and Franceschetto work with logics that have the property of not satisfying any of the formulations of the principle of non contradiction, Béziau and Franceschetto also analyze, among the three-valued logics, which of these logics satisfy this property. They prove that there exist only four of such logics, but only two of them are worthwhile to study. The language of these logics does not consider implication as a connective. However, the enrichment of a language with an (...) implication connective leads us to more interesting systems, therefore we look for one implication for these logics and we study further properties that the logics obtain when this connective is added to these systems.

In memoriam José Arrazola Ramírez The logic $\textbf{G}^{\prime}_3$ was introduced by Osorio et al. in 2008; it is a three-valued logic, closely related to the paraconsistent logic $\textbf{CG}^{\prime}_3$ introduced by Osorio et al. in 2014. The logic $\textbf{CG}^{\prime}_3$ is defined in terms of a multi-valued semantics and has the property that each theorem in $\textbf{G}^{\prime}_3$ is a theorem in $\textbf{CG}^{\prime}_3$. Kripke-type semantics has been given to $\textbf{CG}^{\prime}_3$ in two different ways by Borja et al. in 2016. In this (...) work, we continue the study of $\textbf{CG}^{\prime}_3$, obtaining a Hilbert-type axiomatic system and proving a soundness and completeness theorem for this logic. (shrink)

We propose an extension of answer sets, that we call safe beliefs, that can be used to study several properties and notions of answer sets and logic programming from a more general point of view. Our definition, based on intuitionistic logic and following ideas from D. Pearce [Stable inference as intuitionistic validity, Logic Programming 38 79–91], also provides a general approach to define several semantics based on different logics or inference systems. We prove that, in particular, intuitionistic logic can be (...) replaced with any other proper intermediate logic without modifying the resulting semantics. We also show that the answer set semantics satisfies an important property, the “extension by definition”, that can be used to construct program translations. As a result we are able to provide a polynomial translation from propositional theories into the class of disjunctive programs. (shrink)

This book explores the epistemic side of racial and sexual oppression. It elucidates how social insensitivities and imposed silences prevent members of different groups from listening to each other.

Background The Regional Committee for Africa of the World Health Organization (WHO) in 2001 expressed concern that some health-related studies undertaken in the Region were not subjected to any form of ethics review. In 2003, the study reported in this paper was conducted to determine which Member country did not have a national research ethics committee (REC) with a view to guiding the WHO Regional Office in developing practical strategies for supporting those countries. Methods This is a descriptive study. The (...) questionnaire was prepared and sent by diplomatic pouch to all the 46 Member States in the WHO African Region, through the WHO country representatives, for facilitation and follow up. The data were entered in Excel spreadsheet and subsequently exported to STATA for analysis. A Chi-Squared test (χ 2) for independence was undertaken to test the relationship between presence/absence of Research Ethics Committee (REC) and selected individual socioeconomic and health variables. Results The main findings were as follows: the response rate was 61% (28/46); 64% (18/28) confirmed the existence of RECs; 36% (10/28) of the respondent countries did not have a REC (although 80% of them reported that they had in place an ad hoc ethical review mechanism); 85% (22/26) of the countries that responded to this question indicated that ethical approval of research proposals was, in principle, required; and although 59% of the countries that had a REC expected it to meet every month, only 44% of them reported that the REC actually met on a monthly basis. In the Chi-Squared test, only the average population in the group of countries with a REC was statistically different (at 5% level of significance) from that of the group of countries without a REC. Conclusion In the current era of globalized biomedical research, good ethics stewardship demands that every country, irrespective of its level of economic development, should have in place a functional research ethics review system in order to protect the dignity, integrity and safety of its citizens who participate in research.

In the present article we aim to thematize the conception of personal identity from a historical articulation based on the notion of axial era. With this strategy, we want to pursue a double objective, namely: (i) to explain the concept of the axial age as an important historical axis for Western culture, focusing on the changes in the role of religion in society; and (ii) to trace a certain constitutive image of modern personal identity from such a historical perspective. In (...) this way, we argue that the personal identity of the modern subject is rooted in a certain reconfiguration of the ways in experiencing religion, resulting in a disembedding of the individual in his society and a growing need for self-realization. Then, we aim to offer an alternative opening for the understanding and assimilation of the original speeches in its contrast with the Western culture. (shrink)

In the era of information and communication, issues of misinformation and miscommunication are more pressing than ever. _Epistemic injustice - _one of the most important and ground-breaking subjects to have emerged in philosophy in recent years - refers to those forms of unfair treatment that relate to issues of knowledge, understanding, and participation in communicative practices. The Routledge Handbook of Epistemic Injustice is an outstanding reference source to the key topics, problems and debates in this exciting subject. The first collection (...) of its kind, it comprises over thirty chapters by a team of international contributors, divided into five parts: Core Concepts Liberatory Epistemologies and Axes of Oppression Schools of Thought and Subfields within Epistemology Socio-political, Ethical, and Psychological Dimensions of Knowing Case Studies of Epistemic Injustice. As well as fundamental topics such as testimonial and hermeneutic injustice and epistemic trust, the Handbook includes chapters on important issues such as social and virtue epistemology, objectivity and objectification, implicit bias, and gender and race. Also included are chapters on areas in applied ethics and philosophy, such as law, education, and healthcare. The Routledge Handbook of Epistemic Injustice is essential reading for students and researchers in ethics, epistemology, political philosophy, feminist theory, and philosophy of race. It will also be very useful for those in related fields, such as cultural studies, sociology, education and law. (shrink)

José L. Zalabardo defends a pragmatist account of what grounds the meaning of central semantic discourses--ascriptions of truth, of propositional attitudes, and of meanings. He argues that it is the procedures that regulate acceptance and rejection that give the sentences of these discourses their meanings, and explores the application of the pragmatist template to ethical discourse. The pragmatist approach is presented as an alternative to representationalist accounts of the meaning grounds of declarative sentences, according to which a sentence has (...) the meaning it has as a result of links with the bits of the world that it purports to represent. Zalabardo develops a version of the open-question argument to support the claim that the meaning grounds of the discourses he focuses on cannot receive representationalist accounts. It is generally assumed that a declarative sentence cannot perform the function of representing the world unless it has a representationalist meaning ground. Zalabardo rejects this assumption, arguing that sentences with pragmatist meaning grounds can represent the world in exactly the same sense that sentences with representationalist meaning grounds do. This requires that there are states of affairs that the target sentences represent as obtaining, and Zalabardo develops an account of the nature of the states of affairs that can play this role for sentences with pragmatist meaning grounds. Pragmatist Semantics concludes by developing the suggestion that the meaning grounds of all our representational discourses might be ultimately pragmatist. (shrink)

Una de las dificultades de aproximación que ofrece la Inteligencia Artificial es resultado de la falta de textos, manuales introductorios, ya que la mayoría de la literatura son artículos de revistas o compilaciones de éstos. Uno de los méritos de este libro se basa precisamente en que ofrece una visión global de un area de la Inteligencia Artificial tan fundamental como es el de la Representación del Conocimiento. Como apunta el propio autor, se trata de una introducción desde la perspectiva (...) de la Inteligencia Artificial de las cuestiones fundamentales de la representación del conocimiento, aunque en algunos capítulos se discuten también acercamientos desde la psicología cognitiva. Si bien la extensión de las cuestiones puede parecer limitada en muchos casos, esta brevedad queda compensada por la amplitud y lo acertado de las referencias.

Reliabilist accounts of knowledge are widely seen as having the resources for blocking sceptical arguments, since these arguments appear to rely on assumptions about the nature of knowledge that are rendered illegitimate by reliabilist accounts. The goal of this book is to assess the main arguments against the possibility of knowledge, and its conclusions challenge this consensus. The book articulates and defends a theory of knowledge that belongs firmly in the truth-tracking tradition, and argues that although the theory has the (...) resources for blocking the main standard lines of sceptical reasoning, there is a sceptical argument against which the theory offers no defence, as it doesn’t rely on any assumptions that the theory would render illegitimate. The book ends with the suggestion that the problem might have a metaphysical solution—that although the sceptical argument may make no illegitimate epistemological assumptions, it does rest on a questionable account of the nature of cognition.

Psychologists have demonstrated the value of diversity – particularly diversity of viewpoints – for enhancing creativity, discovery, and problem solving. But one key type of viewpoint diversity is lacking in academic psychology in general and social psychology in particular: political diversity. This article reviews the available evidence and finds support for four claims: (1) Academic psychology once had considerable political diversity, but has lost nearly all of it in the last 50 years. (2) This lack of political diversity can undermine (...) the validity of social psychological science via mechanisms such as the embedding of liberal values into research questions and methods, steering researchers away from important but politically unpalatable research topics, and producing conclusions that mischaracterize liberals and conservatives alike. (3) Increased political diversity would improve social psychological science by reducing the impact of bias mechanisms such as confirmation bias, and by empowering dissenting minorities to improve the quality of the majority's thinking. (4) The underrepresentation of non-liberals in social psychology is most likely due to a combination of self-selection, hostile climate, and discrimination. We close with recommendations for increasing political diversity in social psychology. (shrink)

In Wittgenstein on Rules and Private Language, Saul Kripke rejects some of the most popular accounts of what meaning facts consist in on the grounds that they fail to accommodate the normative character of meaning. I argue that a widespread interpretation of Kripke's argument is incorrect. I contend that the argument does not rest on the contrast between descriptive and normative facts, but on the thought that speakers' uses of linguistic expressions have to be justified. I suggest that the line (...) of reasoning that I attribute to Kripke can be seen as putting pressure on the idea that predicate satisfaction is to be explained in terms of a relation between predicates and properties.

O artigo apresenta os elementos filosóficos constitutivos da crítica, lançada por Jacobi a Fichte em sua Carta a Fichte, segundo a qual “Idealismo é niilismo”. Para tanto, reconstitui a crítica de Jacobi à pretensão idealista de estabelecer um sistema absoluto do conhecimento que, partindo da atividade originária e infinita do pensamento, põe a objetividade do mundo na medida em que o pensa; dá atenção à centralidade do problema do absoluto/de Deus na argumentação de Jacobi e sua relação com as noções (...) de não-filosofia, não-saber e crença, além de apontar para as conexões destas noções com o emergente problema do niilismo na modernidade. Por fim, estabelece um breve contraponto com a filosofia de Nietzsche. (shrink)

The subject matter of this paper is the view that it is correct, in an absolute sense, to believe a proposition just in case the proposition is true. I take issue with arguments in support of this view put forward by Nishi Shah and David Velleman.

Based on published works and unpublished materials, this article analyses how cybernetics was received by two Spanish thinkers exiled in Mexico: José Gaos (1900–1969) and Eduardo Nicol (1907–1990). This reception is particularly intriguing especially when considering the substantial presence and social impact that Norbert Wiener had in Mexican society because of his friendship with Arturo Rosenblueth. Gaos and Nicol are the first philosophers to develop a complex and original diagnosis of cybernetics in Mexico. It will be shown how the (...) exiled thinkers take on the philosophical implications of this science in the light of their respective theoretical projects, and finally, it will be defended how the critical perspective they develop is particularly significant for Mexico’s political and academic context since it illuminates some negative aspects of cybernetics that Wiener did not foresee and that had not been reported there until then.

The concept of political obligation has not attracted much attention within Heideggerian scholarship. In this paper, we identify and explicate Heidegger’s conception of political obligation embedded in his pre-Kehre works. It will be argued that Heidegger’s magnum opus Being and Time and his address as Rector of Freiburg contain a latent associative account of political obligation. We argue that the ontological framework disclosed in Being and Time and the more concrete policy prescriptions of the Rectoral Address reveal a communitarian ethos (...) which animates the early Heideggerian canon and grounds his account of political obligation. For Heidegger, Dasein must be connected to a particular community’s ontological heritage in order to delimit its ontical possibilities in concrete situations. It will be argued that this relationship between ontological heritage and ontical possibilities is what defines political obligation for Heidegger. (shrink)

Tendo como referência O Nascimento da Tragédia de Friedrich Wilhelm Nietzsche, busca-se explicitar a particularidade da concepção nietzscheana de tragédia a partir de um duplo movimento: 1) Reconstrução das principais teses dos primeiros parágrafos da obra; 2) Demonstração da vinculação daquelas teses à tradição estética alemã do final do século XVII e do início do século XIX. Com isso se realça e reedita o diálogo intenso de Nietzsche com aquela tradição e se mostra as inovações e a radicalidade da sua (...) interpretação da tragédia. (shrink)

O artigo tem por objetivo investigar a particular relação que se estabelece entre a temática do início da filosofia – que é de extrema importância para toda a “escola fenomenológica de Freiburg” – e a concepção da essência da filosofia tal como desenvolvida especificamente no pensamento de Martin Heidegger e Eugen Fink. A partir da reinterpretação e radicalização operadas em relação à abordagem estabelecida pela fenomenologia husserliana, mostraremos como a figura de Husserl se impõe tanto como pano de fundo quanto (...) como alvo polêmico das reflexões de Heidegger e Fink. Assim, se o primeiro desenvolve uma concepção da filosofia como práxis radical de um “outro” pensamento, que procede por tentativas e experimentações, o segundo transforma a fenomenologia husserliana no sentido de uma filosofia da liberdade.

O objetivo do artigo é apresentar como Simondon concebe o objeto técnico, a mediação e o ensino refletido da técnica. Num primeiro momento será apresentada a defesa dos objetos técnicos frente a acusação de restrição da experiência humana, da cultura. Num segundo, será apresentada a genealogia do objeto técnico, compreendido enquanto mediação entre o homem e a natureza, para então abordar o tema do ensino refletido da técnica.
