Tras una rápida revisión de los escasos datos conocidos sobre la vida y la obra de Ibn Abi l-Riyal (fl. Túnez c. 996-1048), se analiza el contenido de su Uryuza fi a?kam al-nuyum comparándola con su célebre al-Kitab al- Bari� fi a?kam al-nuyum concluyéndose que se trata de dos obras independientes y que la Uryuza no es un resumen del Bari�. El trabajo continúa con datos biobibliográficos del historiador, matemático y astrólogo Ibn Qunfu? al-Qusan?ini (1339-1407), autor de un comentario a (...) la Uryuza de Ibn Abi l-Riyal dedicado a Abu Bakr b. Abi Muyahid Gazi Ibn al-Kas, visir de los sultanes meriníes Abu Faris (1366-1372) y Abu Zayyan (1372-1374). La obra parece haber sido redactada durante el breve reinado de este último y antes de la deportación del dedicatario a Mallorca en 1375. Se analiza el contenido del comentario, las fuentes citadas en el mismo, las técnicas astrológicas utilizadas tanto por Ibn Qunfuu? como por Ibn Abi l-Riyal y el uso, por parte del comentarista de un ziy derivado del de Ibn Is?aq. El artículo termina con un comentario detallado de los horóscopos contenidos en la obra de los que uno corresponde al equinoccio vernal del año 571 de JC, en el que se produjo una conjunción de Saturno y Júpiter que anunció el advenimiento del Islam, mientras que los once restantes constituyen una historia astrológica del Marruecos meriní entre 1348 y 1366. Dos de ellos habían sido publicados en un artículo anterior. En lo que respecta a los nueve restantes, en seis de ellos se identifica el sujeto o acontecimiento al que aluden, quedando tres por identificar. (shrink)

Ibn al-Bann1321) is the author of one of the four extant of the unfinished zq (fl. Tunis and Marrakesh ca. 1193j accessible for the computation of planetary longitudes. The present paper studies some modifications of the structure of the tables the purpose of which is to make calculations easier. The tables of the planetary and lunar equations of the centre are ' appears as a clever adapter, who displays a clear ingenuity allowing him to introduce formal modifications which give his (...) work an appearance of novelty which does not correspond to reality.

An Andalusian tradition of zījes seems to have been predominant in the Maghrib due to the popularity of the zīj of Ibn Is[hdotu]āq al-Tūnisī and derived texts compiled in the fourteenth century. This tradition computed sidereal planetary longitudes and allowed the calculation of tropical longitudes by using trepidation tables based on models designed in al-Andalus by Abū Is[hdotu]āq ibn al-Zarqālluh. This tradition also used Ibn al-Zarqālluh's model to calculate the obliquity of the ecliptic, which implied that this angle had a (...) cyclical period of oscillation between a maximum of 23;53° and a minimum of 23;33°: after reaching this minimum value the obliquity of the ecliptic was bound to increase. This paper argues that some new Maghribi sources give information on observations made in the Maghrib in the fourteenth and beginning of the fifteenth centuries that imply that precession had increased beyond the limits allowed by the Zarqāllian trepidation theory, while the obliquity of the ecliptic had diminished below the level accepted by astronomers who followed Ibn al-Zarqālluh. This explains the introduction in the Maghrib of Eastern zījes, which computed directly tropical longitudes and did not accept the cyclical variation of the obliquity. Information about observations of dawn and twilight made both in Egypt and in the Maghrib in the fourteenth and fifteenth centuries is also presented. (shrink)

A social history of Andalusi exact sciences should deal with scientific schools, teaching, travels to the East, patronage and scientific professions. I claim that such a social history of Andalusi science is almost impossible because of the lack of sources.

Este libro ofrece una imprescindible riqueza de perspectivas sobre el aspecto más problemático -que coincide con el menos tratado por los investigadores. de la obra de F. Nietzsche (1844-1990): la cuestión política. Nuestro reto de cara al Centenario de su muerte fue encarar lo que suele escamotearse. Y, al menos en este país, así ha sido por regla general. bien porque Nietzsche era "apolítico", otra forma más, como en el caso de otros pensadores, de situarlo universitariamente a la derecha, ángulo (...) desde el que se le importaba, ya porque, consigna progresista y transición filosófica, había que poner esta última interpretación en su sitio y demostrarle al mundo que Nietzsche había sido "utilizado erróneamente" por el totalitarismo nazi, el caso es que ya porque nos repugnaba moralmente aquella lectura, ya porque de tanto estar en favor de Nietzsche tampoco lo leíamos, cuestiones fundamentales de su obra y, por qué no decirlo, irritantes tanto para la derecho como para la izquierda, quedaron piadosamente salvadas. Y ahora ¿qué?... Los trabajos aquí presentados, nacionales e internacionales, han sido rigurosamente seleccionados. (shrink)

This paper explores the ethical dilemma of conflicting loyalties found in whistleblowing. Central to this dilemma is the internal/external disclosure dichotomy; disclosure of organisational wrongdoing to an external recipient is seen as disloyal, whilst disclosure to an internal recipient is seen as loyal. Understanding how the organisation and society have dealt with these problems over the last 30 years is undertaken through an analysis of Vandekerckhove’s project, which seeks to place the normative legitimisations of whistleblowing legislation and organisational whistleblowing policies (...) within a globalisation semantic able to contain this conflict between society and the organisation. This project fails, it is argued, because of Vandekerckhove’s particular understanding of the organisation as an autopoietic system, i.e. an operationally closed system. A case is made to understand organisations as complex systems, i.e. operationally open systems. Critical Complexity theory sees the identities of systems and components as coterminous. In the context of the organisation, this means that the identities of the corporation and its corporate members arise and die together. The whistleblower’s disclosure reconfigures the organisation by forcing the organisation to open up and make its boundaries flexible, making the designation ‘internal’ or ‘external’ to the organisation, and, therefore, who qualifies as a recipient of a disclosure of wrongdoing, flexible. The organisation is restrained from retailing against the whistleblower, because its identities are coterminous. Furthermore, as the disclosure cannot be categorically defined as either internal or external, the question of whether an external disclosure can qualify as an act of organisational loyalty becomes moot.

O presente estudo busca examinar alguns dos debates socrático-platônicos sobre a opinião pública diante da busca da verdade, e seu impacto político, particularmente para a democracia, que depende da noção de liberdade. Depois de se entender o avanço da visão de Platão sobre o problema da opinião e a impossibilidade de seu sobrepujamento geral, discute-se a visão do autor sobre o regime que dá poder ao demos e, ao final, que tipo de aprendizado se pode daí extrair para as democracias (...) contemporâneas.

The texts of the Bible treasure a high amount of theatrical potential. Thus, the book of Job constituted the basis of the Theatrum Mundi . Nevertheless, the Jewish and Christian conception of the world and history, despite its tragedies and Passions, is far removed from Greek tragedy. The figure of Job constitutes a contrast to the tragic in King Lear . An exorcistic formula from the Bible appears in Hamlet, Macbeth, and in plays of the Faustian theme –El mágico prodigioso (...) and Marlowe’s and Goethe’s Fausts –, as well as, surprisingly, in Don Quixote and in many other plays where the devil appears on stage. OscarWilde’s Salome finds inspiration in the language of Song of Songs and of apocalyptic prophecies. Rituality and sacredness are common to the Bible and theatre in the quest for representation of the invisible through the visible. (shrink)

This book presents a conceptual mapping of supererogation in the analytic moral philosophical tradition. It first asks whether supererogation can be conceptualised in the absence of obligation or duty and then makes the case that it can be. It does so by enlisting the resources of the continental tradition, specifically using the work of Emmanuel Levinas and his notion of infinite responsibility. In so doing the book contributes to the ongoing efforts to create a common ethical terminology between the analytic (...) and continental traditions within moral philosophy. Supererogatory actions are praiseworthy actions that go ‘beyond duty’, and yet are not blameworthy when not performed. In responding to this paradox, moral philosophy either brackets or attempts a reductionism of supererogation. Supererogation is epitomised in the paradigmatic figures of the saint and hero. Yet, most would agree that emulating these figures is too morally demanding. We rightly ask: where does moral obligation end? Is it even possible, or desirable to demarcate such a boundary? Besides the important theoretical issues these questions raise, they also speak to practical ethical dilemmas in the contemporary milieu, as they concern the global wealthy’s responsibility to the poor and the challenges of development aid work.

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)

This article has as its theme the democracy as fundamentalism, or the democratic fundamentalism. Its main objective is the recognition that the thinking about democracy can itself be fundamentalist, implying that not only religious fundamentalisms are a threat to contemporary democracy. Its method and object are the interpretation of texts by two contemporary philosophers who do not usually talk to each other, the Italian Gianni Vattimo and the French Jean-Luc Nancy. The essay's thesis is the affirmation of democratic thinking as (...) a form of fundamentalism, insofar as it fulfills certain conditions established by the two thinkers analyzed. These conditions are, in the language of the aforementioned philosophers, the framing of democracy under the so-called strong thought, or its subsumption to a metaphysical way of thought, so that it becomes incapable of self-criticism and its necessary reinvention. Thus, it is expected to contribute to the construction of a self-critical vision of democracy through dialogue with aspects of thought little known of important philosophers and also through the dialogue between philosophy and theology as emancipatory ways of knowing.

This article provides a critical reading of the ‘Parecer CNE-CES 60, de 2014’, from the Ministry of education, Brazil, which defines the curriculum guidelines for courses of Baccalaureate in Theology. In its first section it discusses the theoretical background of the ‘Parecer’, questioning its illuminist orientation, as well as its pedagogical theory focused on contents and not on the students activities. It aims to show that are two opposed educational paradigms in the ‘Parecer’, the illuminist and the constructivist, although the (...) illuminist is the dominant one. It also question the view of the theologian present in the ‘Parecer’, marked by significant absences from the professional field of religious work. In the second section, the article presents a sample of particular interpretation of the ‘Parecer’, indicating the guidelines of a curriculum based on the constructivist paradigm. It dedicates special attention to the occult dimension of the curriculum and to an articulation of the student’s activities in relationship to the disciplines of the course. (shrink)

En 2011 se cumplió el centenario de la publicación del artículo de Husserl “La Filosofía como ciencia rigurosa”; este artículo presenta algunos problemas centrales a que tendría que responder la fenomenología en la actualidad. Los tres campos temáticos son los siguientes: 1) Cuál es la motivación que llevan a la epoché y en qué medida intervienen en ella los actos voluntarios. 2) Hasta qué punto la ampliación de la conciencia es un resultado de un procedimiento reflexivo, o en qué medida (...) participan allí procesos inconscientes. En esta parte se impone revisar las relaciones entre la fenomenología y el psicoanálisis. 3) Cuál es el sentido de los acontecimientos y en qué medida ellos permiten la ampliación o reducción del mundo de la vida. La consideración de la relación entre acontecimiento y acción exige replantear la pregunta por la responsabilidad social de la filosofía. (shrink)

In the context of globalization, the existence of multiple legal cultures appears as a new form of legal pluralism and poses important challenges to jurisprudence and legal theory. On the one hand, the peaceful coexistence of several legal cultures demands a reasonable level of sustainable diversity; on the other hand, the processes of legal convergence can conceal new ways of legal imperialism, by means of legal transplant. In view of this, we understand there is a possibility of building a cosmopolitan (...) law, but this requires a new model of jurisprudence, released from the monist conception of state law, a formula that can go beyond the framework of old 19th century jurisprudence, in order to respond to the new circumstances of interdependence, globalization and multiculturalism.

Inauguration speech at chair number 18 of the Brasilian Academy of Philosophy.

La publicación relativamente reciente de los artículos de la revista japonesa Kaizo, titulados “Renovación del hombre y de la cultura” (1923-1924) y de las lecciones de ética impartidas por Husserl en los años de 1920 y 1924 permite acceder al nuevo rumbo que siguieron sus reflexiones éticas. Asimismo, estos textos permiten comprender la posición crítica de Husserl respecto de su primera versión de su ética, la cual se caracterizaba por ser una doctrina universal de los valores basada en una axiología (...) formal. A partir de los años veinte Husserl presenta una concepción novedosa de su ética, cuya principal base es la resolución del sujeto radical y volitiva por una vida consagrada a la responsabilidad y al amor. Este trabajo presenta cómo fue posible dicho tránsito y los rasgos generales de esta versión de la ética que se puede denominar también “personalista”. (shrink)
