Na atualidade estamos enfrentando uma forte onda de intolerância e tolerância, potencializando e valorizando a Tolerância como sendo um modelo a seguir, e seria a solução para as fortes condutas violentas, discriminatórias e criminosas que estamos sendo vítimas nas relações interpessoais e nas relações entre culturas e países. Tolerar o desigual, o assimétrico é uma luta desigual, do mais forte contra aquele que pela sua realidade social, tem sido enfraquecido. Como formar uma consciência e uma cultura, não do tolerar-aguentar a (...) partir de minhas condições impostas; mas uma cultura de hospitalidade, de acolhida, de abertura ao distante, ao assimétrico e estranho. A hospitalidade incondicional, ou seja, não coloco nenhuma condição, a única condição para acolher ao estrangeiro que chega do além do horizonte, é não ter condições. Desse modo não acolho uma categoria estrangeiro, mas uma pessoa que tem sua individualidade e sua unicidade. Para uma acolhida com hospitalidade é necessário criar um deslocamento na minha interioridade, me acomodar diferente, o outro que chega sempre provoca um movimento interior e exterior no meu eu; quando não acolho ao assimétrico, colocando condições na sua chegada, nada de novo acontece no eu. Acolher com hospitalidade é a possibilidade de nos experimentar diferente e de inaugurar algo novo em nós, na construção de sermos cada vez melhores, mais humanos, solidários e hospitaleiros.

RESUMEN El presente estudio está dirigido a establecer coincidencias entre el pensamiento de José Martí y de Carlos Marx en el terreno filosófico. Ambos representan los más altos exponentes del saber filosófico y humanista de la cultura europea y latinoamericana del siglo XIX, respectivamente, con un alcance genuinamente universal. No fue objetivo en modo alguno convertir a Martí en marxista, del mismo modo que sería absurdo afiliar a Marx a las ideas y las concepciones martianas. Sin embargo, no es posible (...) dejar de subrayar la profundidad del ideario martiano en el terreno filosófico, político, social y económico y sus aproximaciones a las concepciones marxistas o al socialismo científico. ABSTRACT The present study is directed to establish coincidences between the thought of José Martí and Carlos Marx in the philosophical area. Both are represented by the highest exponents of the philosophical and humanist knowledge of the European and Latin-American culture of the 19th century, respectively, with an authentically universal scope. It was not objective in any way to turn Martí into Marxist, in the same way that it would be absurd to affiliate Marx to the ideas and the Martí´s conceptions. Nevertheless, it is not possible to stop underlining the depth of the Martí´s ideology in the philosophical, political, social and economic area and his approaches to the Marxist conceptions or to the scientific socialism.

A set A of vertices of a graph G is called d-scattered in G if no two d-neighborhoods of (distinct) vertices of A intersect. In other words, A is d-scattered if no two distinct vertices of A have distance at most 2d. This notion was isolated in the context of finite model theory by Ajtai and Gurevich and recently it played a prominent role in the study of homomorphism preservation theorems for special classes of structures (such as minor closed classes). (...) This in turn led to the notions of wide, almost wide and quasi-wide classes of graphs. It has been proved previously that minor closed classes and classes of graphs with locally forbidden minors are examples of such classes and thus (relativized) homomorphism preservation theorem holds for them. In this paper we show that (more general) classes with bounded expansion and (newly defined) classes with bounded local expansion and even (very general) nowhere dense classes are quasi wide. This not only strictly generalizes the previous results but it also provides new proofs and algorithms for some of the old results. It appears that bounded expansion and nowhere dense classes are perhaps a proper setting for investigation of wide-type classes as in several instances we obtain a structural characterization. This also puts classes of bounded expansion in the new context. Our motivation stems from finite dualities. As a corollary we obtain that any homomorphism closed first order definable property restricted to a bounded expansion class is a restricted duality. (shrink)

The origin of chordates and the consequent genesis of vertebrates were major events in natural history. The amphioxus (lancelet) is now recognised as the closest extant relative to the stem chordate and is the only living invertebrate that retains a vertebrate‐like development and body plan through its lifespan, despite more than 500 million years of independent evolution from the stem vertebrate. The inspiring data coming from its recently sequenced genome confirms that amphioxus has a prototypical chordate genome with respect to (...) gene content and structure, and even chromosomal organisation. Pushed by joint efforts of amphioxus researchers, amphioxus is now entering a new era, namely its maturation as a laboratory model, through the availability of a large amount of molecular data and the advent of experimental manipulation of the embryo. These two facts may well serve to illuminate the hidden secrets of the genetic changes that generated, among other vertebrates, ourselves. (shrink)

This paper offers a comparison between the aristocratic radicalism of Nietzsche and that of the Colombian philosopher, Nicolás Gómez Dávila, in order to point out their points of contact and their differences. This leads to the analysis of the uneven reception of their ideas, which at the same time ..

This article provides an introduction to the themed section ‘Anarchism and the national question—historical, theoretical and contemporary perspectives.’ We discuss first the long and often overlooked engagement of anarchists with the colonial and national liberation question, particularly—but not exclusively—in the heyday of the movement (from the second half of the 19th to the first decades of the 20th century). We discuss in particular the overlaps and tensions between anarchists and republicans (those who favoured republics as opposed to monarchies) and anti-colonial (...) nationalists (anti-colonialists who defended the right of national self-determination). Then we proceed to discuss the potential for a dialogue between anarchist and nationalism studies based on three interventions. First, to problematise the narrative that conflates nations with state-building processes. Second, to better grasp the emergence of alternatives to the nation–state as a historical construct. Third, to complicate narratives that associate in an unproblematic fashion internationalism and classless society. Finally, the introduction highlights the four questions which lie at the core of the themed section and discuss briefly how the papers relate to these. (shrink)

Networks or partnerships are used by humans since the beginning of humanity and its analysis raises concerns from many different sectors of society. In the era of the network of networks, Internet, networks are generated by virtual connections of the agents. Social Network Analysis studies the relationship relation to each other, the social structure. It is an area that is emerging as essential in decision-making processes for its ability to analyze and intervene in the behaviour of structures. We analyze three (...)

Hablar de emancipación en la sociedad neoliberal, es cuestionar ciertos principios y valores de democracia participativa donde la noción de ciudadanía pública debe ser ampliada más allá de la mera discusión de carácter ético; precisamente, porque la democracia ciudadana es un concepto que defi..

El artículo lleva a cabo un breve recorrido a través del cuestionamiento filosófico de la noción de causalidad. Nos interesará mostrar las inevitables implicaciones metafísicas de esta noción, que han llevado o bien a querer eliminarla del dominio de la ciencia, o bien a asumir su carácter fundamentalmente subjetivo y el riesgo de un posible relativismo.

Las investigaciones de la fenomenología de la imaginación esclarecen la distinción kantiana entre belleza libre y dependiente. La imaginación estética fluye libremente, el entendimiento fija en concep tos. El juego libre entre imaginación y entendimiento produce un equili brio inestable entre la inquietud de la imaginación y el reposo del enten dimiento. El sentido común permite que ese juego sea comunicado. Según nuestra hipótesis la belleza libre es libre también del sentido común. Su sede no es la esfera pública y (...) la comunicación, sino la esfera privada de la imaginación pura. En ella encontramos la auténtica autono mía estética. (shrink)

La experiencia política que sustentó la Polis clásica, pareció a quienes reflexionaron filosóficamente sobre ella, inevitable e incluso natual; desde la filosofía contemporánea se la puede considerar, además, existenciaria y aporética. En la Atenas del siglo V a.C. encontramos fórmulas políticas que ponen de manifiesto la fuerza que, en la expresión de lo público, tienen las vivencias estéticas, el mito y la metáfora. Llama la atención en ellas la aspiración a perfeccionar los modos humanos de pervivir, convivir y pertenecer según (...) modelos vitales .The political experience which the classical i’olis’ was based on seenied unavoidable and even natural to those who philosophically reflected on it; besides, it can be considered, from the view of the contemporary philosophy, existenciary’ and aporetic. In V b.C. Athenes, we can find political formulae which show the strength which connected to the expression of Ihe public matters, is hold by aesthetic experience, myth and metaphor. Something Ithat attracts our attention about then is the wish to make perfect the human ways of living on, living together and belonging according lo the patterns relatedto life experience. (shrink)

Si la filosofía de la razón vital de Ortega concedió tanta importancia a los asuntos artísticos fue precisamente porque ella misma se constituyó como una filosofía estética. Ahora bien, es necesario aclarar en qué sentido puede afirmarse esto último, pues una mala comprensión del carácter estético de la filosofía de la razón vital podría poner en peligro la pretensión de racionalidad que Ortega defendió siempre para la filosofía.

El texto constituye una reseña-comentario a dos volúmenes que celebraban desde México, con inteligente selección, abierta a la controversia, el 80 aniversario (1995) del destacado pensador hispano-mexicano. Se trataba de los libros Adolfo Sánchez Vázquez: los trabajos y los días y En torno a la obra de Adolfo Sánchez Vázquez, editados por Federico Álvarez y Gabriel Vargas Lozano, respectivamente. El título del comentario hace alusión a la permanente actitud de principios de Sánchez Vázquez, quien mantuvo, primero, una actitud crítica ante (...) el marxismo ortodoxo y dogmático que se difundía desde la URSS y el llamado socialismo real y, después, asumió estoicamente la defensa del marxismo cuando aquellos habían desaparecido.

Los autores que dialogan en el número 27 de Ístmica con sus respectivos cuentos; el guatemalteco Francisco Alejandro Méndez y el costarricense Iván Molina Jiménez, han encontrado maneras subrepticias y transtemporales de erizarnos la piel a través de la narrativa que nos ofrecen en esta edición. Méndez (1964), es periodista, crítico literario, catedrático universitario y reconocido escritor del istmo, quien obtuvo el Premio Nacional de Literatura de Guatemala en el 2017. Ha publicado los siguientes libros de novela y (...) cuento: Graga y otros cuentos (Editorial Serviprensa Centroamericana, Guatemala, 1991), Manual para desaparecer (Arco Iris, El Salvador, 1997), Sobrevivir para contarlo (Praxis, México, 1999), Crónicas suburbanas (Editorial X, Guatemala, 2001), Ruleta rusa (Fondo de cultura económico, México-Guatemala, 2001), Completamente Inmaculada (Perro azul, San José de Costa Rica, 2002), Reinventario de ficciones. Catálogo marginal de bestias, crímenes y peatones (La Tatuana, Guatemala, 2006), Les ombres du jaguar et autres nouvelles (Éditions Equilibrio, París, 2009), Juego de muñecas. Un caso más para Wenceslao Pérez Chanán, (Editorial FLACSO, Guatemala, 2012) y Triple Play, (Germinal, Costa Rica, 2013).Como investigador, también ha publicado los siguientes ensayos de crítica literaria: América Central en el ojo de sus críticos (Universidad Rafael Landívar, Guatemala, 2005), Hacia un nuevo canon de la vanguardia en América Central (Ed. Cultura, Guatemala, 2006) y Diccionario de Autores yCríticos de Guatemala (La Tatuana, Guatemala, 2010).Por su parte, Molina (1961), es historiador y escritor de ciencia ficción costarricense, autor, coautor o editor de numerosos estudios sobre historia de CostaRica, en particular, y de Centroamérica, en general. Es catedrático de la Escuela de Historia e investigador del Centro de Investigación en Identidad y CulturaLatinoamericanas (CIICLA) de la Universidad de Costa Rica. Ha obtenido el Premio Nacional de Historia (1991), el Premio de la Academia de Geografía eHistoria (1991), el Premio Áncora del periódico La Nación (1992), el Premio al Investigador en Ciencias Sociales (2015) y el Premio Luis Ferrero de Investigación Cultural (2016). Entre sus investigaciones más recientes figuran: La educación en Costa Rica de la época colonial al presente (EUNA, Costa Rica, 2016) y Príncipes de las remotidades. Carlos Luis Fallas y los escritores proletarios costarricenses (EUNED, Costa Rica, 2016). En el género de la ciencia ficción hapublicado varios libros de cuentos cortos y algunos de sus relatos han sido incluidos en recopilaciones y revistas publicadas en México, Colombia, Perú, España, Argentina, Estados Unidos y Cuba. Su más reciente libro de ciencia ficción es Las fugitivas de Abidos (La Jirafa y Yo, Costa Rica, 2017).En los cuentos de ambos autores que presentamos en esta edición, confluyen la creación de una atmósfera de suspenso, que puede originar desde aparentes alucinaciones hasta revivir temores atávicos. En este encuentro convergen monstruos reales y ficticios -aunque nos cueste diferenciarlos-, así como las neurosis del siglo XXI y las leyendas del siglo XIX, que aliviadas unas por el psicoanálisis y alimentadas otras, por los primeros experimentos de “ingeniería genética”, consiguen sembrarnos una interrogante sobre la (in)distinción de lo real en nuestro entorno.

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)

A prepositional logic S has the Converse Ackermann Property (CAP) if (AB)C is unprovable in S when C does not contain . In A Routley-Meyer semantics for Converse Ackermann Property (Journal of Philosophical Logic, 16 (1987), pp. 65–76) I showed how to derive positive logical systems with the CAP. There I conjectured that each of these positive systems were compatible with a so-called semiclassical negation. In the present paper I prove that this conjecture was right. Relational Routley-Meyer type semantics are (...) provided for each one of the resulting systems (the positive systems plus the semiclassical negation). (shrink)
