Traveler, come with us! Do not be afraid. You will see sublime and melancholy, gay and beautiful scenes. Poet! Down there you will find poetic themes worthy of your most inspired verses. Artist! For you there are pictures of admirable freshness, painted by the hand of God. Writer! There you will encounter legends not yet written, legends of love and hate, of gratitude and vengeance, of hypocrisy and abnegation, of noble virtues and repugnant crimes; legends of fragrant romanticism and rich (...) in truth. Let us go there, plowing the dark and agitated waves of the restless Atlantic, through the islands of the Antilles, to the shores of Anáhuac.In the strictest sense, the Occident, (that prestigious union of nations, ideologies of progress, and export and import companies) discovered Mexico in the 19th century. Only at the end of Spanish domination—that never understood that “there are various kinds of excellence”—did other countries and Mexico itself begin to learn of the scope of the Conquest and regions affected by it, partially replacing Spanish mythology with another, more varied but equally remote. The greatness of the ancient Indians and their happy age was praised, while the living natives were reviled; the idealization of the pre-Columbian, which had been suspended by priests and encomenderos, was continued (Hernández wrote in 1577, “In this new world signs of avarice had never penetrated, nor had ambition been born until our compatriots arrived, carried by ships and the wind”); the possibilities of the new country were greedily examined; scornful notes were taken on the successive and simultaneous failures in the attempt to create a republic; the vices and virtues of those who were suddenly free were enumerated; a climate favorable to invasions and the amputation of territories was created; customs were observed with joy or alarm.

Cet article propose une interprétation de la philosophie de la Nouvelle Académie différente de celle qui a été défendue par J. Annas. Il nous semble que la prise en compte de l'ensemble des témoignages concernant cette école suggère une réalité plus complexe que celle que recouvre le concept de scepticisme, au moins dans sa version néopyrrhonienne. Nous croyons qu'Arcésilas et Carnéade n'ont pas délimité un Platon sceptique, mais qu'ils ont accepté à leur manière l'ensemble de l'héritage platonicien. La force de (...) la tradition apparaît donc plus forte dans l'histoire de l'Académie que ne l'admettent généralement les interprètes. The purpose of this article is to give an interpretation of the New Academy's philosophy quite different from the one defended by J. Annas. In our opinion the reading of the whole testimonies relating to this school suggests a greater complexity than what is embraced by the concept of skepticism, at least in its neopyrrhonian version. We believe that Arcesilas and Carneades, instead of confining Plato whithin the limits of skepticism, have accepted - in their own way - the whole Platonician legacy. Thus the burden of tradition seems more important in the history of the Academy than it is generally admitted. (shrink)

The present text surveys and reevaluates the meaning and scope of Ortega y Gasset’s philosophy. The chapters reveal the most important aspects of his history such as the Neokantian training he went thru in Germany as well as his discovery of Husserl’s phenomenology around 1912. The work also covers his original contributions to philosophy namely vital and historical reason - and the cultural and educational mission he proposed to achieve. The Spanish – and to a certain extent the European – (...) circumstance was the milieu from which his work emerged but this does not limit Ortega’s scope. Rather, he believed that universal truths can only emerge from the particulars in which they are embedded. The publication in 2010 of a critical edition of his Complete Works opened worldwide access for many unpublished manuscripts, and some of his lectures. There is renewed interest among students and researchers in Ortega and this book uniquely delivers scholarship on his content in English. (shrink)

A indústria cultural tem nos aniversários mais diversos oportunidades de (auto) celebração com virtualidades cada vez mais exploradas. Neste caso interessa-nos a celebração dos 150 anos do nascimento de Freud, embora outros exemplos, à primeira vista até mais originais, fossem possíveis (como a ainda recente azáfama em torno dos 250 anos do terramoto de Lisboa). O que torna o caso dos 150 anos de Freud tão interessante é ver como em seu torno se procedeu à habitual evocação festiva, típica da...

The goal of this study was to test the role of message framing for effective communication of self-care behaviors in the context of the COVID-19 pandemic, contrasting health and economic-focused messages. We presented 319 participants with an unforced choice task where they had to select the message that they believed was more effective to increase intentions toward self-care behaviors, motivate self-care behaviors in others, increase perceived risk and enhance perceived message strength. Results showed that gain-frame health messages increased intention to (...) adopt self-care behaviors and were judged to be stronger. Loss-framed health messages increased risk perception. When judging effectiveness for others, participants believed other people would be more sensitive to messages with an economic focus. These results can be used by governments to guide communication for the prevention of COVID-19 contagion in the media and social networks, where time and space for communicating information are limited.

À plusieurs égards, il est vrai d’avancer que Maïmonide et Averroès poursuivent le même projet philosophique et religieux. D’autant plus que tous deux ont été décrits comme des disciples d’al-Fârâbî, le fondateur de l’école de l’aristotélisme arabe . Cependant, à première vue, leur oeuvre ne pouvait pas être moins ressemblante: Averroès n’a écrit presque exclusivement que des commentaires sur Aristote, cependant que Maïmonide n’est l’auteur d’aucune oeuvre qui appartienne à un genre philosophique dans le sens strict. Il est, d’un autre (...) côté, un commentateur distingué lui aussi - sauf qu’il n’explique pas Aristote, mais commente et met de l’ordre dans la Loi de Moïse. La question principale dont je traite dans cet article, est celle de savoir si ce rapport tellement différent à la philosophie et à l’exégèse chez Averroès et Maïmonide peut être compris comme deux façons d’implémenter le cadre conceptuel établi par al-Fârâbî. Je commence par examiner le projet d’al-Fârâbî, que j’essaie d’expliquer par deux objectifs: reprendre et continuer le projet de la philosophie antique et définir sa place dans une société, dans laquelle l’autorité de la Loi divine n’est pas mise en question. Ensuite, je montre que, tandis que l’oeuvre d’Averroès peut être comprise, dans l’ensemble, comme une continuation du projet d’al-Fârâbî, cela n’est pas vrai de la même façon pour l’oeuvre de Maïmonide qui en partie transforme al-Fârâbî de manière créative et en partie utilise des prémisses dont on ne trouvera pas la source en al-Fârâbî. La position de Maïmonide en ce qui concerne la philosophie et l’exégèse se distingue significativement de la position habituelle adoptée par les falâsifa, ce qui a eu des conséquences importantes pour la philosophie juive médiévale après Maïmonide.

This commentary focuses on the importance of attention skills in the development of universal associative learning, and it explains why the centrality of attention in UAL presents a considerable difficulty for the UAL approach. Attentional abilities are not just developmentally related to UAL but are in fact explanatory of UAL. The main problem is that all the types of attention involved in UAL can be dissociated from consciousness. This means that while attention skills for UAL might be necessary for consciousness, (...) they are not sufficient because they can all occur unconsciously. Thus, the possibility that UAL capacities might not be sufficient for consciousness cannot be eliminated, thereby challenging the key claim of the UAL approach. (shrink)

This book offers an account of exile in terms of the perspectives of morality, politics, literature, anthropology, and history. It also explores the moral implications of exile and how it connects to the meaning of life.

Quantified hybrid logic is quantified modal logic extended with apparatus for naming states and asserting that a formula is true at a named state. While interpolation and Beth's definability theorem fail in a number of well-known quantified modal logics , their counterparts in quantified hybrid logic have these properties. These are special cases of the main result of the paper: the quantified hybrid logic of any class of frames definable in the bounded fragment of first-order logic has the interpolation property, (...) irrespective of whether varying, constant, expanding, or contracting domains are assumed.

This work identifies a recurring element in Paul Ricœur1s thought, namely that of carrying out a hermeneutic graft in specialized areas of knowledge that deal with certain philosophical problems, which will be demonstrated in the following topics, where they will be presented: i) the phenomenological investigation into the privileged access to the cogito, in The Conflict of Interpretations — Essays in Hermeneutics; ii) the epistemological and ontological problems of access to the historical past, as well as the relationship between historiography (...) and fictional literature, in Time and Narrative; iii) the question of personal identity in the analytical tradition of the philosophy of language, in Oneself as Another; iv) finally, the limits of the naturalistic approaches of neurosciences and cognitive sciences on memory in Memory, History, Forgetting and What makes us think?. The philosopher, in The Conflict of Interpretations, openly claims to promote a grafting of the hermeneutic problem into the phenomenological method in his investigation into the understanding of oneself based on the conflict between rival interpretations concerning the cogito. Jean Greisch, in turn, suggests the existence of a graft not assumed by Ricœur of hermeneutics in the philosophy of language in Oneself as Another. Along the same path, this work offers as a novelty the encounter of two other tacit hermeneutic grafts in Ricœur’s work, namely the hermeneutic graft in the phenomenology of time in Time and Narrative and in the naturalized treatment of memory by neurosciences in Memory, History, Forgetting and What makes us think?.

Según Oliver Marchart, autores como Badiou, Lefort, Rancière o Laclau son parte de una misma corriente: el pensamiento político posfundacionalista. Su caracte-rística central no es el rechazo de todo fundamento del orden político, sino de todo fundamento que pretenda ser necesario. En oposición a esta postura y, a partir de un análisis del concepto de hegemonía, se busca mostrar cómo el pensamiento de Laclau no se libra de la metafísica, sino que, por el contrario, desarrolla políticamente la que es -según (...) Heidegger, el padre espiritual del posfundacionalismo- su forma consumada: la metafísica nietzscheana de la voluntad de poder. According to Oliver Marchart, authors such as Badiou, Lefort, Rancière or Laclau are representatives of postfoundationalist political thought, which does not reject all foundations of the political order, but rather those that claim to be necessary. In opposition to this viewpoint and on the basis of an analysis of the concept of hegemony, the paper seeks to show how Laclau's thought fails to free itself of metaphysics. Rather, it develops politically that which according to Heidegger, the "spiritual father" of postfoundationalism, is its consummated form: Nietzsche's metaphysics of the will to power. (shrink)

We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkin-style completeness proofs even when the modal logic being hybridized is higher-order. The key ideas are to add nominals as expressions of type t, and to extend to arbitrary types the way we interpret $@_i$ in propositional and first-order hybrid logic. This means: interpret $@_i\alpha _a$ , where $\alpha _a$ is an expression of any type $a$ , as an expression of type $a$ that (...) rigidly returns the value that $\alpha_a$ receives at the i-world. The axiomatization and completeness proofs are generalizations of those found in propositional and first-order hybrid logic, and (as is usual inhybrid logic) we automatically obtain a wide range of completeness results for stronger logics and languages. Our approach is deliberately low-tech. We don’t, for example, make use of Montague’s intensional type s, or Fitting-style intensional models; we build, as simply as we can, hybrid logicover Henkin’s logic. (shrink)

En este trabajo, el autor analiza las contradicciones que el multiculturalismo plantea en las sociedades actuales, resaltando la importante mediación que el sistema político democrático lleva a cabo en la resolución de las mismas. A partir de los artículos de tres autores ('The Politics ofRecognition" de CH Taylor: "Struggles for Recognition in Constitutional States" de J. Habermas y "Legitimacy and Diversity: Dialectical Reflections on Analytical Distinctions" de T. McCarthy) y de la referencia final al trabajo de Rawls 'The Law of (...) the People", expone una serie de momentos teóricos que representan diferentes estadios en la discusión entre el pensamiento liberal y el comunitarismo, y que componen un proceso explicativo en el que cada uno de esos momentos supondría una superación teórica del anterior. En concreto, el autor trata de situar la discusión sobre el reconocimiento del derecho a la diferencia, en el terreno en el que del análista del modelo teórico del liberalismo más acorde con el reconocimiento de derechos a las colectividades-el republicanismo comunitarista al que se refiere Taylor-, se pase al análisis del tipo de sistema político dentro del cual se reconozca la diferencia y la existencia de otras culturas como algo que ya estaba implícito en la teoría de los derechos. Este sistema político sería la democracia deliberativa y su procedimiento discursivo para tomar decisiciones y llegar a acuerdos, propuesto por J. Habermas. El trabajo de McCarthy tratarla de resolver algunas fisuras en la democracia deliberativa que afectarían a su legitimidad por cuanto suponen un menoscabo a la idea misma de las diferencias. Finalmente, la alusión a Rawls permite al autor erigir el sistema de los derechos humanos en el estándar mínimo necesario para llegar a un acuerdo global lo suficientemente amplio y abstracto como para garantizar el máximo respeto a las diferencias. Un acuerdo que, insiste el autor, sólo puede enmarcarse en un proyecto democrático con dimensión internacional, al que llama "horizonte cosmopolitamente democrático". (shrink)

The contemporaneous ecological concern constitutes a tread line issue; the distance from superficial activist actions, although, as well as the credible philosophical - phenomenological - background that support the request for the stem cause, distinguishes and outstands Abram ‘s reflection. His poetic and prophetically discourse calls upon the need for a extremely disavowal reorganisation of the position of Man and his task within the cosmos.

In this article, we formally define and investigate the computational complexity of the definability problem for open first-order formulas with equality. Given a logic $\boldsymbol{\mathcal{L}}$, the $\boldsymbol{\mathcal{L}}$-definability problem for finite structures takes as an input a finite structure $\boldsymbol{A}$ and a target relation $T$ over the domain of $\boldsymbol{A}$ and determines whether there is a formula of $\boldsymbol{\mathcal{L}}$ whose interpretation in $\boldsymbol{A}$ coincides with $T$. We show that the complexity of this problem for open first-order formulas is coNP-complete. We also (...) investigate the parametric complexity of the problem and prove that if the size and the arity of the target relation $T$ are taken as parameters, then open definability is $\textrm{coW}[1]$-complete for every vocabulary $\tau $ with at least one, at least binary, relation.

O presente artigo se constrói no marco teórico da Análise de Discurso (AD) de linha francesa, considerando as reformulações e ampliações que têm sido propostas no Brasil. A temática abordada é constitutiva do discurso editorialista em torno da Democracia e da dinâmico do jogo político no cenário nacional. Nosso olhar repousa nos saberes próprios das formações discursivas que são constitutivas do discurso da imprensa enquanto forma de produção da opinião pública. Analisamos as marcas linguístico-discursivas buscando tornar visíveis as formas de (...) dizer do discurso da mídia e as relações com suas condições de produção. As estruturas homogeneizadas pelo dizer comportam relações com implícitos e com um imaginário já instituído. No interdiscurso, buscamos o contínuo discursivo desencadeado pelo discurso da imprensa e neste o funcionamento ideológico que se possibilita no jogo discursivo que ali se apresenta. (shrink)

The author deals with one aspect of the justification of governmental action and its product (the law). He focuses on the authoritative character of legal rule, analyzing the apparent capacity of governments to produce reasons for action not grounded on substantive moral considerations. The assumption of that capacity seems necessary in order to establish a general moral obligation to obey a government irrespective of the actions required. This question is faced in connection with the thesis that only a particular form (...) of government, democracy, is morally justified insofar as it rests on legal rules issued by a legitimate source.

Ha llegado a ser un lugar común aseverar la influencia de Kant en la obra de Rawls; sin embargo, el constructivismo político significó un rechazo del universalismo que es imposible explicar en términos kantianos. Lo que sigue es un intento de evaluar la tesis del consenso superpuesto a la luz de la concepción general de la filosofía política y la razón práctica en Hegel.

We investigate the expressive power of memory logics. These are modal logics extended with the possibility to store (or remove) the current node of evaluation in (or from) a memory, and to perform membership tests on the current memory. From this perspective, the hybrid logic (↓), for example, can be thought of as a particular case of a memory logic where the memory is an indexed list of elements of the domain.

Wittgenstein defiende que los problemas filosóficos son ilegítimos. Sin embargo, no resulta del todo claro qué se entiende en general por problema filosófico, cuál es, pues, su naturaleza. El presente artículo intenta elucidar la observación de Wittgenstein que sostiene que la forma de un problema filosófico se puede presentar con la expresión “Yo no sé salir del atolladero” (IF § 123). En el artículo se elige, a manera de ejemplo, el escándalo kantiano, que demanda que demostremos con el uso de (...) la razón que la proposición “hay objetos físicos” es verdadera. Sin renunciar al ejemplo, se explora en qué sentido la expresión de Wittgenstein caracteriza en buena medida la naturaleza misma de la dificultad filosófica. En el ejercicio se atienden recomendaciones formales del Tractatus, terapias desplegadas en Sobre la Certeza y el recurso de distinguir entre sentido primario y sentido secundario de una expresión insinuado en las Investigaciones Filosóficas.
