The diversity in colour patterns on butterfly wings provides great potential for understanding how developmental mechanisms may be modulated in the evolution of adaptive traits. In particular, we discuss concentric eyespot patterns, which have been shown by surgical experiments to be formed in response to signals from a central focus. Seasonal polyphenism shows how alternate phenotypes can develop through environmental sensitivity mediated by ecdysteroid hormones, whereas artificial selection and single gene mutants demonstrate genetic variation influencing the number, shape, size, position, (...) and colour composition of the eyespots. The expression patterns of the regulatory gene Distal-less reveal that these changes can arise at several different developmental stages, and the phenotypes indicate that some forms of changed pattern may occur much more readily than others. Further study of the genes, of the developmental mechanisms, and of the functions of the patterns will provide novel insights about the evolution of morphological diversity.

El autor realiza una lectura de las Enéadas de Plotino partiendo de la noción de procesión, pieza clave para comprender la arquitectura del universo plotiniana ordenado jerárquicamente alrededor del Uno-Bien.Del primer principio proceden todos los seres y en él convergen. Cuatro son fundamentalmente los aspectos tratados: 1) El axiomade la procesión. 2) Los dos momentos de la procesión: el ascendente y el descendente. 3) Las imágenes de la procesión.4) Dentro de estas metáforas, privilegia el centro y el círculo, núcleo en (...) el análisis de la noción de procesión.

In this paper, I argue that the certainty about the wrongness of killing must not be considered as a universal, but as a local one. Initially, I show that there exist communities in which the wrongness of killing innocents is not a moral certainty and that this kind of case cannot be justified by arguing that such people are psychopaths. Lastly, I argue that universal certainties do not admit of exceptions: thus, the fact that some exceptional cases affect the certainty (...) that killing innocents is wrong, leads me to conclude that it is a local certainty.

Resumen El autor confiesa que pertenece a la generación que ha dedicado su vida a implementar la herencia del Concilio Vaticano II, generación que ha tenido a ese concilio como el punto de referencia más importante - eclesialmente hablando - en los últimos 40 años. Sin embargo, aventura la hipótesis de que la problemática del Vaticano II ha quedado ya obsoleta, y lo justifica presentando tres olas de nuevos signos de los tiempos que han transformado radicalmente el panorama teológico y (...) pastoral: la teología de la liberación, el pluralismo religioso y la crisis de la religión. El artículo trata de las grandes olas que avalan esa superación: la teología y la espiritualidad de la liberación, la teología del pluralismo religioso y la revisión de paradigma que provoca la actual crisis de la religión. Estas tres "superaciones" del Vaticano II son, pues, las que nos permiten pensar que lo que se dirimió en el Concilio ya no es el punto de referencia principal de la vida de la Iglesia, ni de las necesidades religiosas más urgentes de la Humanidad. Palabras clave: Concilio Vaticano II; Cambio de paradigma; Teología de la liberación; Pluralismo religioso; Crisis de la religión.The author belongs to the generation that has dedicated its life to implement the heritage of Vatican Council II, and has taken that Council as the most relevant point of reference, in ecclesiastical terms, for the last 40 years. However, he formulates the hypothesis that the problematics of Vatican II has become obsolete, and justifies that viewpoint presenting three new waves that have transformed radically the theological and pastoral panorama: the theology of liberation, religious pluralism and the crisis in religion. The article focuses on the signs that support such surpassing: the theology and spirituality of liberation, the theology of religious pluralism and the review of paradigms that has brought about the current crisis in religion. Those three signs of "surpassing" Vatican II, therefore, make us think that what was rendered void in the Council is no longer the main point of reference of Church life, nor of mankind's most urgent religious needs. Key words: Vatican Council II; Shift of paradigm; Theology of liberation; Religious pluralism; Crisis of religion. (shrink)

La “Teología del pluralismo religioso” (TPR) no es una teología “sectorial”, o “de genitivo”, que teologizara temas nuevos dentro de la “universa theologia”. O sea, la TPR no agranda cuantitativamente el campo de la teología. Hace su aportación, pero cualitativamente: trata los mismos temas, pero bajo una luz distinta, con otra pertinencia, otro “objeto formal”. Es una teología que replantea todo desde otra perspectiva, con otro ordenamiento, a partir de otro “paradigma”. Por eso, los desafíos de esta teología son fuertes. (...) Grandes perspectivas generales nunca antes cuestionadas, se derrumban ahora, y surgen otras nuevas, desafiantes. El autor se centra en una selección de los principales cambios que producen esos desafíos actuales. Los aborda y trata de justificarlos, mostrando en cada caso sus implicaciones para la reflexión teológica y para la vida cristiana. El paso de una valoración negativa del pluralismo a otra positiva, la nueva comprensión de la Revelación, la superación y hasta el abandono de la categoría de “elección”, las principales propuestas de cambio en campos tan sensibles como los de la cristología, la eclesiología y la moral, así como la transformación de la misión son las cuestiones de esto breve estudio. Palabras clave: Pluralismo; Cambio de paradigma; Pluralismo de principio; Elección; Inclusivismo; Misión. ABSTRACT The Theology of religious pluralism (TRP) is not “a sectorial” theology or “a genitive theology”, which would theologize new subjects, that is to say one more field inside the “universa theologia”. In other words, it does offer a quantitative novelty instead of a qualitative one. TRP deals with the same subjects, but from another point of view, another “formal object”. Everything is retrieved from another order, point of view, and “paradigm”. In this way, challenges seem to be huge. Great general perspectives that have never been are effected and new challenges reappear. The author works on the selection of main changes that produce current challenges. Such Challenges are presented and justified, showing in each case its implications for theological reflexion and well as for Christian life. The core of this brief study refers to the shift of a negative to a positive evaluation of the religious pluralism, a new understanding of the Revelation, the overcoming and the abandon of the category of the “election”, the main challenges in the sensible field of christology and moral, as well as the transformation of the mission. Key words: Pluralism; Shift of paradigm; Pluralism of principle; Election; Inclusivismo; Mission. (shrink)

In this paper I will argue that when Aristotle uses the word ‘ἀρχή’ he is often referring to what we call a condition, whether necessary, sufficient or necessary and sufficient. To this end I will discuss how conditions for being, change, and knowledge, as identified by Aristotle, can be equated to ontological, physical and noetic principles, respectively.

El artículo examina el papel de Crescas y Spinoza en la transición de la concepción medieval a la concepción moderna del universo. Crescas es presentado como ejemplo ilustrativo de la tensión entre aristotelismo y religión revelada y de cómo esta última provoca la disolución del aquel, allanando así el camino a la concepción moderna del universo. A continuación, se muestra cómo la concepción moderna se plasma en el pensamiento de Spinoza, el cual radicaliza algunos de sus rasgos definitorios. Esta radicalización (...) socava la noción tradicional del _Deus absconditus_ y conduce en Spinoza al remplazo de la religión por la filosofía como auténtica revelación divina. (shrink)

Literature on indoctrination has focused on imparting and revising beliefs, but it has hardly considered the way of teaching and acquiring certainties—in Wittgenstein’s sense. Therefore, the role played by rationality in the acquisition of our linguistic practices has been overestimated. Furthermore, analyses of the relationship between certainty and indoctrination contain major errors. In this paper, the clarification of the aforementioned issues leads me to suggest the avoidance of the term ‘indoctrination’ so as to avoid focusing on the suitability of the (...) case to the concept rather than on the analysis of the case itself. This should facilitate that the process of helping children to acquire a world-picture—by teaching them to ignore alternatives to certainties—is definitely accepted as normal and natural, for many beliefs are expected to end up becoming ungrounded certainties not only in the medium or long term, but also, and above all, in the short term.

After describing Wittgenstein's notion of ‘certainty’, in this article I provide four arguments to demonstrate that no certainty can be acquired at will. Specifically, I argue that, in order to assimilate a certainty, it is irrelevant whether the individual concerned has found a ground that seemingly justifies that certainty; has a given mental state; is willing to accept the certainty on the proposal of a persuader; or tries to act according to the certainty involved. Lastly, I analyse how each of (...) these arguments is reflected in the way children acquire certainties. (shrink)

It is expected that children increasingly learn to identify errors throughout their schooling process and even before it. As a further step, however, some scholars have suggested how a culture of error should be implemented in the classroom for the student to be able not only to locate errors but also, and above all, to learn from them. Yet the various proposals aimed at generating a culture of error in the classroom keep regarding error as all those responses and reactions (...) that are not considered as true or correct in each specific case, thereby not realizing that many of these alleged errors are really anomalies with very different characteristics and consequences despite their seeming resemblance. In this paper, I rely on Ludwig Wittgenstein’s On Certainty to clarify the difference between errors and anomalies. Subsequently, I provide guidelines that may be adapted by each teacher to her students’ needs and development level in order to foster a culture of error that begins by distinguishing er... (shrink)

Wittgenstein scholars have tended to interpret the acquisition of certainties, and by extension, of a world-picture, as the achievement of a state in which these certainties are assimilated in a seemingly unconscious way as one masters language-games. However, it has not been stressed that the attainment of this state often involves facing a series of challenges or difficulties which must be overcome for the development of the world-picture and therefore the socialization process to be achieved. After showing, on the one (...) hand, how a world-picture is usually developed, and on the other hand, why a child who seemingly found itself trapped in a precocious skepticism might have serious problems in assimilating certainties, in this paper, I describe some of the challenges children often meet as they acquire a world-picture. Since the overcoming of these challenges is often needed for children to develop a world-picture, I aim at raising the awareness of the necessity of ‘learning to believe’, that is, of developing a series of skills that allow children to undertake the challenges described in this paper.

El articulo examina la aparente discrepancia en el pensamiento de Spinoza entre su teocentrismo epistemológico, según el cual todo es dudoso mientras desconocemos la existencia de Dios, y el principio verum index sui et falsi, según el cual la mera posesión de ideas verdaderas excluye toda incertidumbre. Lejos de contradecirse, estas dos afirmaciones constituyen en Spinoza dos aspectos correlativos del mismo planteamiento gnoseólogico. Se muestra así que la naturaleza divina no es ajena al intelecto humano y que este es capaz (...) de contemplar la realidad desde una perspectiva omnímoda, idéntica a la de Dios. (shrink)

El objetivo del presente trabajo es especular sobre los factores que pueden llevar a un posible retorno del Estado en general y del Estado de Bienestar en particular, después de la etapa neoliberal que podría haberse cerrado con las crisis contemporáneas. Se trata de ver si la tendencia hacia el “Estado mínimo” se ha revertido, cosa que ya pudo haberse iniciado a finales del siglo XX, e incluso si el conjunto de crisis mundiales acaecidas a principios del XXI no habrán (...) acelerado tal tendencia. De todos modos, podría darse el caso de un retorno del Estado pero con un planteamiento sobre el Estado de Bienestar bien diferente del que tuvieron los que, a finales del siglo XIX y principios del XX, comenzaron a implantarlo en países centrales.

An analysis of the particular kind of determinism that is to be found in the moral election according to Leibniz shows the model of practical reason held in his philosophy. The hermeneutical clue used in the article is to make a parallelism between the model of rationality of God’s election to create the best possible world and that of human moral election.

Los recientes movimientos sociales (desde las “primaveras árabes” a Occupy Wall Street, pasando por los “indignados” europeos o los estudiantes latinoamericanos) pueden entenderse mejor, sin negar sus componentes locales, si se perciben como alternativas producidas dentro de la lógica del sistema capitalista. A ello se añade la actual coyuntura de inseguridades producidas por la crisis visible desde 2008, que agudiza los motivos de protesta. Ésta, sin embargo, no es mayoritaria, y sus integrantes se plantean -con dificultad- objetivos y medios, al (...) tiempo que oscilan entre la búsqueda de cambios en el sistema y su generalización hacia un cambio de sistema.

Though Wittgenstein's On Certainty has been influential in analytic epistemology, its interpretation has been enormously controversial. It is true that exegesis has been mainly concerned with the proper characterization of Wittgenstein's very notion of ?certainty?; however, some important questions remain unanswered regarding this notion. On the one hand, I am above all referring to the study of the possibilities we have of retaining a certainty when it has seemingly been placed into question and, on the other hand, of regaining a (...) certainty once it has been lost. In this paper, I attempt to provide a detailed answer to both questions. In so doing, some important features of the picture of ourselves which emerges from Wittgenstein's On Certainty are also revealed. (shrink)

Algunos autores han intentado considerar los delirios como certezas –entendidas en el sentido de Wittgenstein– debido a las similitudes que parecen existir entre sus respectivos estatus epistemológicos. Sin embargo, dicho intento ha sido criticado con agudeza, entre otras razones, porque el contenido de los delirios choca frontalmente con el contenido de las certezas, por lo que los delirios no pueden ser comprendidos debido a los cambios en las relaciones de significado. Pero es evidente que, aunque los delirios no se puedan (...) contemplar como certezas, muchos delirios afectan de un modo u otro al sistema de certezas del paciente. Partiendo de esta base, no es descabellado pensar que dicha influencia pudiera ser también recíproca: en otras palabras, parece sumamente recomendable analizar si algunos delirios se podrían contemplar como el resultado de variaciones en certezas. En este artículo llevo a cabo dicho análisis al intentar mostrar que el origen de algunos delirios pedestres y severos puede ser hallado en lo que llamaré “ceguera a posibilidades” e “incertidumbre”, términos que he desarrollado teniendo en cuenta la obra del filósofo Ludwig Wittgenstein.

This paper presents the concept of ‘religious certainty’ I have developed by drawing inspiration from Wittgenstein’s notion of ‘certainty’. After describing the particular traits of religious certainty, this paper addresses two difficulties derived from this concept. On the one hand, it explains why religious certainty functions as such even though all its consequences are far from being absolutely clear; on the other hand, it clarifies why, unlike the rest of certainties, the loss of religious certainty does not result in the (...) collapse of the world-picture made up of all certainties. Subsequently, it analyzes to what extent the teacher can teach religious certainty by acting as a facilitator for its acquisition–if desired—particularly bearing in mind that religious certainty cannot be attained at will. These basic teaching guidelines have several advantages. First, they make it possible to know the nature of religious certainty even better. Second, and most importantly, the fact of having adopted the perspective of a teacher who tries inculcating a religious certainty contributes to detecting and preventing forms of indoctrination that, arguably, might go unnoticed even when attempting to properly present religious certainty—or rather, this way of being religious—in current schools to foster understanding thereof.

In this paper, I describe the main lines of modern error theory, a systemic theory which regards errors not as the results of someone’s negligence, but as parts of a complex system. Bearing in mind that errors must be considered as such by an observer or attributor, I expose Wittgenstein’s conception of the attributor responsible for discerning if a strange event constitutes an error or an anomaly. Subsequently, I illustrate this conception of the attributor by describing some traits of the (...) role played by many attributors in business organizations, specifically in the production line of a car manufacturer’s plant, when carrying out the rootcause analysis of problems that arise in the plant. Finally, I reveal a paradox whereby if the attributor denies the possibility that anomalies may happen without being able to explain their source within the system that he or she takes as reference, then the very idea of system no longer makes sense.

Wittgenstein’s conception of ‘persuasion’, understood as the persuader’s attempt to modify the persuadee’s certainties, has been recently misinterpreted by some scholars. For Persichetti has overlooked the fact that one cannot persuade unintentionally, while Marconi and Perissinotto have not only taken for granted that persuasion consists in the mere transfer of a world-picture or set of certainties to an individual even when she has not alternative or different certainties, but also that education is restricted to persuading or transmitting certainties. After clarifying (...) these misinterpretations, among others, I argue that persuasion is not used for teaching certainties at the outset, but for modifying them when they do not fit the ones expected by the persuader. If it is agreed that education partly consists in transmitting a world-picture, then persuasion constitutes a necessary resource for educators. Lastly, I provide a set of guidelines for teachers to draw attention to the basic aspects of persuasion that they should consider in the classroom. (shrink)

El artículo examina la conexión esencial que existe entre la concepción hegeliana del signo y el funcionamiento del discurso especulativo en la Ciencia de la lógica. Partiendo de la tensión irresuelta en la filosofía kantiana entre la capacidad significativa del discurso y su autorreferencialidad, se somete a consideración el intento hegeliano de resolver dicha tensión en su tratamiento del lenguaje, contenido en la Enciclopedia de las ciencias filosóficas. De esta manera se pone al descubierto el modo sutil en que la (...) concepción hegeliana del signo permite superar las restricciones que Kant impone al discurso filosófico sin contravenir la prescripción básica de la filosofía crítica, según la cual todo pensamiento debe asociarse con una intuición para poder constituir un conocimiento con pretensión de validez. A partir de este resultado y centrándose en la estructura misma del signo tal y como la conceptualiza Hegel, se intenta esclarecer el funcionamiento exacto del discurso lógico y de los momentos básicos que lo constituyen –entendimiento, dialéctica y especulación–, mediante el ejemplo concreto de las tres primeras determinaciones de la Lógica: Ser. Nada y Devenir. (shrink)

Hegel's main criticisms of Spinoza are well‐known both among Spinoza and Hegel scholars. The role of Spinozism in Hegel's conception of philosophy turns out to be significantly more crucial than the rest of philosophies. This chapter argues that Spinoza's acosmism constitutes for Hegel the necessary condition for the rise and development of philosophy, and hence for the realization of human freedom, insofar as philosophy is the highest form of human freedom. It outlines the general conception of philosophy behind Hegel's statement (...) that Spinozism constitutes “the essential beginning of all philosophizing.” In Hegel's view, the greatness of Spinozism lies precisely in the radical de‐substantialization of finite things that it carries out, that is, in its acosmism.” Spinoza's acosmism clears the ground for the free exercise and unfolding of philosophical thinking.
