In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

In some recent articles, Cobreros, Egré, Ripley, & van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a nontransitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of Cut (...) involving semantic notions. In this article we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have nontrivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this article is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this article, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be nontrivially achieved if self-reference is expressed through identities.

When discussing Logical Pluralism several critics argue that such an open-minded position is untenable. The key to this conclusion is that, given a number of widely accepted assumptions, the pluralist view collapses into Logical Monism. In this paper we show that the arguments usually employed to arrive at this conclusion do not work. The main reason for this is the existence of certain substructural logics which have the same set of valid inferences as Classical Logic—although they are, in a clear (...) sense, non-identical to it. We argue that this phenomenon can be generalized, given the existence of logics which coincide with Classical Logic regarding a number of metainferential levels—although they are, again, clearly different systems. We claim this highlights the need to arrive at a more refined version of the Collapse Argument, which we discuss at the end of the paper. (shrink)

Many authors have considered that the notions of paraconsistency and dialetheism are intrinsically connected, in many cases, to the extent of confusing both phenomena. However, paraconsistency is a formal feature of some logics that consists in invalidating the rule of explosion, whereas dialetheism is a semantical/ontological position consisting in accepting true contradictions. In this paper, we argue against this connection and show that it is perfectly possible to adopt a paraconsistent logic and reject dialetheism, and, moreover, that there are examples (...) of non-paraconsistent logics that can be interpreted in a dialetheic way. (shrink)

In this paper, we present a non-trivial and expressively complete paraconsistent naïve theory of truth, as a step in the route towards semantic closure. We achieve this goal by expressing self-reference with a weak procedure, that uses equivalences between expressions of the language, as opposed to a strong procedure, that uses identities. Finally, we make some remarks regarding the sense in which the theory of truth discussed has a property closely related to functional completeness, and we present a sound and (...) complete three-sided sequent calculus for this expressively rich theory.

"This book presents a theoretical discussion of problems and issues encountered in the Native American community from a perspective that accepts Native knowledge as legitimate. Native American cosmology and metaphor are used extensively in order to deal with specific problems such as alcoholism, suicide, family, and community problems. The authors discuss what it means to present material from the perspective of a people who have legitimate ways of knowing and conceptualizing reality and show that it is imperative to understand intergenerational (...) trauma and internalized oppression in order to understand the issues facing Native Americans today."--pub. website.

A theory of truth is usually demanded to be consistent, but -consistency is less frequently requested. Recently, Yatabe has argued in favour of -inconsistent first-order theories of truth, minimising their odd consequences. In view of this fact, in this paper, we present five arguments against -inconsistent theories of truth. In order to bring out this point, we will focus on two very well-known -inconsistent theories of truth: the classical theory of symmetric truth FS and the non-classical theory of naïve truth (...) based on ᴌukasiewicz infinitely valued logic: PAᴌT.

Em sua obra de “The Reluctant Modernism of Hannah Arendt”, Seyla Benhabib faz o exercício de questionar a formação da concepção arendtiana de modernidade. Retornando à biografia de Rahel Varnhagen, a comentadora aponta para a experiência privilegiada dos salões berlinenses como referências mais interessantes para se pensar a esfera pública, derivando daí um possível universalismo moral de Hannah Arendt. Após expor esta tese de Benhabib, apontamos, em sentido diverso, para a impossibilidade deste exercício em Arendt, mostrando que os salões não (...) poderiam se constituir como referência para a esfera pública por não favorecerem a atividade da ação.

La adaptación cinematográfica de novelas va más allá de la transposición de la narrativa de un medio de expresión a otro e implica a una serie de discursos que están presentes en la obra y que son activados por el lector-espectador en función de su competencia cultural. La música, presente en ambos medios, es capaz de vehicular mensajes que, aunque no se encuentren en la estructura narrativa de las obras, participan en la creación de significados. En este artículo abordamos un (...) análisis formal y discursivo de la música popular en Alta fidelidad y The Commitments, dos novelas adaptadas al cine en las que la ideología de la cultura rock se manifiesta en personajes y espacios. Canciones, músicos e instrumentos aparecen en texto escrito, diálogos, imagen y sonido en las novelas de Roddy Doyle y Nick Hornby y sus respectivas adaptaciones cinematográficas de Alan Parker y Stephen Frears, demostrando la condición multimedia de la música como lenguaje y su capacidad para interactuar con la estructura narrativa y articular sus propios discursos de forma paralela.

This seminal, multidisciplinary book shows how mathematics can be used to study the first principles of DNA. Most importantly, it enriches the so-called "Chargaff's grammar of biology" by providing the conceptual theoretical framework necessary to generalize Chargaff's rules. Starting with a simple example of DNA mathematical modeling where human nucleotide frequencies are associated to the Fibonacci sequence and the Golden Ratio through an optimization problem, its breakthrough is showing that the reverse, complement and reverse-complement operators defined over oligonucleotides induce a (...) natural set partition of DNA words of fixed-size. These equivalence classes, when organized into a matrix form, reveal hidden patterns within the DNA sequence of every living organism. Intended for undergraduate and graduate students both in mathematics and in life sciences, it is also a valuable resource for researchers interested in studying invariant genomic properties.

In this paper we develop a general representation theory for MV-algebras. We furnish the appropriate categorical background to study this problem. Our guide line is the theory of classifying topoi of coherent extensions of universal algebra theories. Our main result corresponds, in the case of MV-algebras and MV-chains, to the representation of commutative rings with unit as rings of global sections of sheaves of local rings. We prove that any MV-algebra is isomorphic to the MV-algebra of all global sections of (...) a sheaf of MV-chains on a compact topological space. This result is intimately related to McNaughton’s theorem, and we explain why our representation theorem can be viewed as a vast generalization of McNaughton’s theorem. In spite of the language used in this abstract, we have written this paper in the hope that it can be read by experts in MV-algebras but not in sheaf theory, and conversely. (shrink)

Resumen: La tolerancia es un privilegio de los poderosos. Una persona puede tolerar sólo si tiene el poder para interferir con aquello que objeta. En este artículo analizaré las circunstancias en las que alguien tiene el poder para tolerar. Argumentaré que la respuesta debe incorporar consideraciones tanto prácticas como metafísicas. Específicamente, defenderé que alguien tiene el poder para tolerar cuando sus propiedades fundan tal poder en la situación práctica en que ella se encuentra, según es caracterizada por sus intereses prácticos. (...) Al hacerlo criticaré el análisis del mencionado poder realizado por Glen Newey. (shrink)

Este artículo trata el problema de los objetos creados que pueden ser repetidos, como las obras musicales y las literarias. En la sección 2 presentamos una serie de desiderata intuitivos que toda teoría debe satisfacer. En las secciones 3 y 4 presentamos un silogismo disyuntivo extendido. Los objetos en cuestión pueden ser o bien universales concretos, particulares concretos, universales abstractos o particulares abstractos. Mostramos cómo es que las teorías que consideran que son cualquiera de las tres últimas opciones fracasan. Por (...) lo tanto, debemos entender a dichos objetos como universales concretos. En la sección 5 ofrecemos una teoría breve pero detallada de la naturaleza metafísica de los universales concretos para después mostrar cómo esta propuesta permite dar cuenta de los desiderata intuitivos a la vez que se evitan las objeciones presentadas en contra de teorías alternativas.

Tratou-se de pesquisa de revisão crítica da literatura no campo da epistemologia. Partiu-se da hipótese das paixões “tóxicas”, isto é, de que existe uma analogia funcional entre as paixões e as toxicomanias devido à função do excesso narcísico, semelhante, mas não idêntica, em ambas. O objetivo foi introduzir os fundamentos teóricos dos métodos de pesquisa qualitativa desta hipótese, partindo-se do raciocínio por analogia na direção da semiologia psicanalítica. Mais precisamente, pretendeu-se discutir, em nível introdutório, alguns fundamentos teóricos destes métodos vistos (...) como análogos, com dupla finalidade: equacionar uma formulação da hipótese das paixões “tóxicas” de acordo com estes métodos; e estruturar um plano de estudo teórico de caráter psicanalítico, em debate interdisciplinar, adequado a esta formulação, a ser executado em outras investigações a partir da aplicação destes métodos na pesquisa desta hipótese.

RESUMEN Este trabajo se propone analizar los aportes de Judith Butler a las actuales lecturas norteamericanas sobre la introducción del deseo en la Fenomenología del espíritu de Hegel. Para ello, en primer lugar, situamos la aparición del deseo en la obra mencionada; en segundo lugar reconstruimos los principales lineamientos de las interpretaciones estadounidenses en boga; en tercer lugar nos ocupamos del análisis que Butler realiza sobre esta cuestión en Sujetos del deseo. Reflexiones hegelianas en la Francia del siglo XX. Por (...) último, en la conclusión, sistematizamos las contribuciones de Butler, destacando fundamentalmente tres: la significación particular que le otorga al deseo en su momento de emergencia; el modo de abordaje de esta problemática que se detiene en el estudio del tercer capítulo de la Fenomenología del espíritu; y la perspectiva retórica desde la que explica el deseo. ABSTRACT This paper aims to analyze Judith Butler's contributions to the recent interpretations of the introduction of desire in Hegel's Phenomenology of Spirit, proposed by American scholars. In order to achieve this goal, we situate the appearance of desire in Hegel's Phenomenology of Spirit. Then, we reconstruct the main recent American readings. Finally, we examine Butler's interpretation. In the conclusion of this paper, we systematize the most important features of Butler's reading: the meaning of desire in the context of its moment of emergency; the way in which Butler studies this issue, which consist in a thorough reading of chapter III ofHegel's Phenomenology of Spirit; and Butler's rhetorical perspective of desire.

: One of the most compelling problems in science consists in understanding how living systems process information. After all, the way they process information defines their capacities to learning and adaptation. There is an increasing consensus in that living systems are not machines in any sense. Biological hypercomputation is the concept coined that expresses that living beings process information non-algorithmically. This paper aims at proving a positive understanding of “non-algorithmic” processes. Many arguments are brought that support the claim. This foster, (...) it is argued, a brand-new understanding of information processing among living beings. (shrink)

Rare events have happened ever since the beginning of this universe. However, they have very recently become the subject of study and a category. This paper studies what rare events are and explores a series of epistemological consequences, thereafter, along with its complexity. The paper introduces a brand new understanding about the sciences of complexity, namely the study of unpredictable phenomena. Unpredictability is the ground, the problem, and the support for complexity as such, something that has never been openly set (...) to the fore in the bibliography about the field. Los eventos raros han sucedido desde el comienzo de este universo y, sin embargo, la tematización y categorización de los mismos es un fenómeno perfectamente reciente. Este artículo estudia qué son los eventos raros y explora la tesis y consecuencia de tipo epistemológico y su complejidad. El texto permite por lo demás una nueva comprensión sobre las ciencias de la complejidad, a saber, el estudio de fenómenos impredecibles. La impredecibilidad constituye el piso, el problema y el soporte de la complejidad misma, algo que jamás ha sido puesto explícitamente de manifiesto en la bibliografía sobre el tema. (shrink)

El último año un número significativo de países desarrollados y del tercer mundo iniciaron procesos de transformación social y política a partir de levantamientos, revoluciones y movimientos impulsados por una ciudadanía hasta ahora distanciada e incluso segregada de la esfera política. En algunos países el imperio del mercado, en otros la fuerza represiva de regímenes autoritarios, en los más privilegiados, un nihilismo extendido producto del bienestar material acumulado, venía desde hace añ..

Mathematical proofs aim to establish the truth of mathematical propositions by means of logical rules. Some recent literature in philosophy of mathematics alleges that some mathematical proofs also reveal why the proved mathematical propositions are true. These mathematical proofs are called explanatory mathematical proofs. In this paper, I present and discuss some salient problems around mathematical explanation: the existence problem, the normative problem, the explanandum problems of truth value and psychological value, the logical structure problem, the regress problem and the (...) modelling problem. At the end, I sum up two contemporary models for mathematical explanation – the deductive-nomological model and the model of Steiner. I analyse these models against the previous problems. (shrink)

Transhumanism proposes human enhancement while regarding the human body as unfit for the future. This fulfills age-old aspirations for a perfect and durable body. We use “alienation” as a concept to analyze this mismatch between human aspirations and our current condition. For Hannah Arendt alienation may be accounted for in terms of earth- and world-alienation, as well as alienation from human nature, and especially from the given (“resentment of the given”). In transhumanism, the biological body is an impediment to human (...) accomplishment. At most, this movement accepts “clean” bodies, not bodies with excretions. We argue that real human bodies are valued in the event of giving birth, so a modified concept that Arendt proposed, natality, seems a suitable way to explore the dialectic alienation-reconciliation involving the body (Arendt’s “A child has been born unto us”), when re-read by some feminist scholars.

En esta discusión abordo la hermenéutica analógica de Mauricio Beuchot comparándola con la hermenéutica filosófica de Hans-Georg Gadamer. Argumento que Beuchot vuelve a la idea clásica de la hermenéutica como método de interpretación y no la juzga, como Gadamer, como una fenomenología de la comprensión. Sin embargo, Beuchot no atiende las razones de Gadamer en contra de concebir la hermenéutica como una metodología. Si se considera como metodología centrada en la analogía, la hermenéutica analógica deja de lado otros recursos interpretativos (...) importantes. Finalmente, Beuchot adopta una teoría correspondentista de la verdad contra la que argumenta Gadamer y que es incompatible con una hermenéutica filosófica. In this paper I analyze Mauricio Beuchot's analogical hermeneutics by contrasting it with Hans-Georg Gadamer's philosophical hermeneutics. I argue that Beuchot goes back to the classical idea of hermeneutics as a method of interpretation, and does not see it, as Gadamer does, as a phenomenology of understanding. However, Beuchot does not address Gadamer's arguments against using hermeneutics as a methodology. Considered as a methodology centered on analogy, analogical hermeneutics overlooks other important interpretation resources. Finally, Beuchot adopts a correspondence theory of truth, which Gadamer objects and is incompatible with philosophical hermeneutics. (shrink)

Después de evaluar los componentes básicos de la violencia desde el punto de vista de las ciencias sociales (la aplicación -o la amenaza de aplicación- de una fuerza física intensa de forma deliberada con la intención de causar efectos sobre el receptor de la misma), se señalan dos elementos definitorios de la violencia: su carácter relacional y su virtualidad transgresora de los derechos fundamentales de la persona. En la segunda parte de la exposición se pasará a exponer las cuatro grandes (...) tendencias de definición del problema: la estructural o extensa, la observacional, la intrínseca o legitimista y la relacional.

El presente artículo presenta parte de los resultados de un estudio de percepción y opinión pública realizado en las quince regiones de Chile, sobre la relación entre descentralización, desarrollo regional y gestión pública. El supuesto del que se parte es que la voluntad de descentralización de la ciudadanía y los actores sociales es un factor facilitador del desarrollo de las regiones. Se entiende por desarrollo regional el conjunto de los procesos políticos, sociales y económicos conducidos por los actores regionales articulados (...) en función de unas prioridades definidas por ellos mismos. Antecediéndolo lógicamente se asume que existe una heterogeneidad regional que proviene de la configuración histórica y cultural de las regiones, y que esta diversidad define una desigualdad en las condiciones iniciales para articular el desarrollo endógeno de cada región.

A esta bibliografía hemos prestado una especial atención en el presente artículo.….

I try to show that Steiner's theory has very implausible normative consequences since it does not accept the prima facie character or rights. This theory is unable to solve the conflicts of interests in which the only intuitively plausible solution consists in overriding someone's rights.
