A solidão tem sido descrita na literatura filosófica recente como uma emoção que envolve uma atitude de aprovação em relação a certos bens sociais, como companhia ou intimidade, juntamente com a consciência de sua temporária ou permanente inacessibilidade. Isso implica que a solidão é uma emoção essencialmente ligada à interação social, uma reação afetiva dolorosa à ausência de bens sociais. Neste artigo, buscamos demonstrar a existência de uma forma de solidão que pode ser chamada de solidão crônica. A solidão crônica (...) não envolve centralmente a falta de envolvimento social, mas sim uma dolorosa experiência intrapessoal de autoabsorção e uma sensação de não pertencimento ao mundo. Tal forma de solidão pode ser descrita não como uma emoção, mas como uma atmosfera afetiva - uma forma afetiva psicopatológica abrangente e de profundo significado moral em virtude do sofrimento emocional e existencial que provoca em seus portadores. Nesse artigo, oferecemos uma caracterização da estrutura da experiência corporal e da experiência de si na solidão crônica. Procuramos mostrar que, como uma atmosfera afetiva abrangente, a solidão crônica afeta nossa inserção corporificada no mundo - o mundo passa a aparecer como distante, não-envolvente ou ameaçador- e a experiência de si. Com ajuda de textos filosóficos, literários e estudos empíricos, argumentamos que essa sensação é vivenciada em contextos de eventos disruptivos, como a pandemia e na síndrome de estresse pós-traumático.

The ambiguous-cue task is composed of two-choice simultaneous discriminations involving three stimuli: positive (P), ambiguous (A) and negative (N). Two different trial types are presented: PA and NA. The ambiguous cue (A) served as an S- in PA trials, but as an S+ in NA trials. When using this procedure, it is typical to observe a less accurate performance in PA trials than in NA trials. This is called the ambiguous-cue effect. Recently, it was reported in starlings that the ambiguous-cue (...) effect decreases when the stimuli are presented on an angled (120°) panel. The hypothesis is that the angled panel facilitates that the two cues from each discrimination are perceived as a compound, precluding value transfer via a second-order conditioning mechanism. In this experiment, we used pigeons and a flat panel. Nevertheless, our data were quite similar to the previous data in starlings. We conclude that the form of the panel cannot explain the ambiguous-cue effect. Several alternatives to be explored in future experiments are suggested. The riddle of the ambiguous-cue problem still remains unsolved. (shrink)

The concept of sustainable development is here revised in the light of a brief historical analysis, followed by a semantic analysis of the expressions development and sustainability. The authors criticize the common use of this concept in a loose way or in wide generalizations, to conclude, based on the principles of human ecology, that it is only possible to make it operational in limited spans of time and in limited spatial units.

O objetivo do texto é problematizar a existência de um possível pensamento informacional ibero-americano. Para tanto, inicialmente constata-se uma relativa ausência da Ibero-América nas apresentações e mapeamentos internacionais da ciência da informação. A seguir, é discutida a realidade dos 22 países que compõem a Ibero-América, região que pode ser compreendida a partir de uma perspectiva sociocultural e geopolítica. Logo após, é feito um panorama, ainda em estágio inicial, das pesquisas em ciência da informação destes países, ressaltando-se a necessidade de continuidade (...) e aprofundamento desse mapeamento. Por fim, apresenta-se uma configuração epistemológica geral da ciência da informação, em nível mundial, evidenciando-se a importância de se situar, nesse quadro, as contribuições específicas da Ibero-América.

Analysis of a diverse cross‐sample of plant‐insect interactions suggests that the abundance of vitamin C (L‐ascorbic acid, ascorbate or AsA) in plants influences their susceptibility to insect feeding. These effects may be mediated by AsAs roles as an essential dietary nutrient, as an antioxidant in the insect midgut, or as a substrate for plant‐derived ascorbate oxidase, which can lead to generation of toxic reactive oxygen species. Ascorbate can also influence the efficacy of plant defenses such as myrosinases and tannins, and (...) alter insects' susceptibility to natural enemies. Conversely, herbivores appear to influence both de novo synthesis and redox cycling of AsA in their host plants, thereby potentially altering the nutritional value of crops and their susceptibility to pests. The recent development of genetically modified crops with enhanced AsA content provides both an impetus and a tool set for further studies on the role of AsA in plant‐insect interactions. (shrink)

El Problema de la Adopción afirma que ciertas leyes lógicas no pueden ser adoptadas. El argumento constituye un desafío al antiexcepcionalismo lógico, en la medida en que este último debe poder justificar su afirmación de que la teoría lógica en ejercicio puede revisarse. El propósito de este artículo es responder al desafío, utilizando como unidad de análisis el concepto de Taxonomía Lexical propuesto por Kuhn. Como mostraremos, una visión sociológicamente enriquecida de las teorías científicas y la naturaleza de sus cambios (...) permite dar cuenta de un antiexcepcionalismo lógico que evita el Problema de la Adopción.

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.

RESUMEN El artículo responde algunas críticas planteadas por Ignacio Ávila a mi interpretación de la epistemología davidsoniana. Presento argumentos en contra de: a) que sea necesario distinguir entre representaciones epistemológicamente “peligrosas”e “inofensivas”; b) que el empirismo mínimo sea un tipo de realismo directo; c) que mi uso de la expresión “evidencia distal” y el interés por la teoría de la correspondencia sean asuntos ajenos a Davidson. Finalmente, sostengo que la triangulación es un elemento fundamental de la epistemología davidsoniana, pues permite (...) sortear la ansiedad realista manteniéndose en una postura no representacionalista. ABSTRACT In this article, I respond to some of Ignacio Ávila's criticisms of my interpretation of Davidson’s epistemology. I argue against: a) the need to distinguish between epistemologically “dangerous” and “harmless” representations; b) the idea that minimal empiricism is a kind of direct realism; and c) the claim that my usage of the expression “distal evidence” and interest in the theory of correspondence are issues that do not pertain to Davidson. Finally, I claim that triangulation is a key element in Davidsonian epistemology since it allows us to deal with the realist anxiety while maintaining a non-representationalist viewpoint. (shrink)

Hybrid languages are expansions of propositional modal languages which can refer to worlds. The use of strong hybrid languages dates back to at least [Pri67], but recent work has focussed on a more constrained system called $\mathscr{H}$. We show in detail that $\mathscr{H}$ is modally natural. We begin by studying its expressivity, and provide model theoretic characterizations and a syntactic characterization. The key result to emerge is that $\mathscr{H}$ corresponds to the fragment of first-order logic which is invariant for generated (...) submodels. We then show that $\mathscr{H}$ enjoys interpolation, provide counterexamples for its finite variable fragments, and show that weak interpolation holds for the sublanguage $\mathscr{H}$. Finally, we provide complexity results for $\mathscr{H}$ and other fragments and variants, and sharpen known undecidability results for $\mathscr{H}$. (shrink)

How can evil exist in a world governed by providence? That is the main question addressed in this chapter. To answer it, the author first sets out Proclus’ defence of providence, which combines the gods’ transcendence with their sharing goodness. The next step is to show that despite providence, evils have reality as well. There is, however, no substance or principle of evil, and only human and irrational souls and material bodies are susceptible to it. Evil’s having a ‘parhypostasis’ is (...) explained as its existing upon and alongside real existents; uncaused because a result of weakness, not power; not pure privation because parasitic on good existents, and hence a ‘subcontrary’ of the good. Finally, the author returns to the relation between providence and evil, showing that bodily evil fits the good of the universe, and that providence will punish evil souls in due course. (shrink)

IN THE DISCUSSION on education in the Republic, Socrates lays down the principles which those who speak about the gods must follow if they want to avoid the errors of traditional mythology. The first typos of this rational theology is this: "God is the cause, not of all things, but only of the good." For "God, being good, cannot be responsible for everything happening in our life, as is commonly believed, but only for a small part. For we have a (...) far smaller share of good than of evil, and while God must be held to be the sole cause of good, we must look for some other factors than God as cause of the evil." Rightly celebrated, this passage has set the agenda for ages of reflection in Western thought on the cause of evil. In contrast to traditional mythology where the gods are seen as the origin of both good and evil--as Homer says, "Zeus has two jars standing on the floor of his palace, full of fates, good in one and evil in the other"--the divinity is now freed of all responsibility for evil. God, who is entirely good, can only be the cause of well-being. If this answer sets God free of all responsibility for evil, it seems to be at the cost of limiting God's power: for God is no longer responsible for "most things in human life," since most of them are evil. What, then, may be the cause or causes of evil? Do bad things have a cause? Or do they just happen? Plato's formulation seems to suggest that he favours a dualistic solution to the problem of evil: God is the cause of all good, but for evil we have to find other causes. What could those causes be: matter, cosmic necessity, an evil soul? Various answers of this type were developed in later Platonism and in later mythological philosophies. Without denying that Plato often uses a dualistic discourse and uses elements of it in his cosmology, I do think that Plato had something different in mind. After all, he was not primarily interested in the problem of theodicy. For in this passage of the Republic, he is not concerned with the problem of evil in the universe as a whole, which is really the theodicy question, but with evil in "human life," that is, evil insofar as human beings experience it and suffer from it: the fact that we are not at all living well but are instead miserable and unhappy.

La logique spécifique des jugements de valeur est à chercher dans le discours rhétorique. Cette thèse développée par Ch. Perelman dans L'Empire rhétorique (1977) nous rappelle l'introduction à l'éthique de Jean Buridan (XIVe s.). Selon Buridan la philosophie morale ne peut se contenter d'appliquer la logique générale: elle a besoin d'une logique spéciale, une „logique morale” qui n'est rien autre que la technique persuasive qu'on étudie dans la Rhétorique. Roger Bacon (XlIIe s.) a même essayé d'intégrer cette rhétorique dans l'éthique (...) : elle est la partie pratique de la science morale. Bien que leur textes rappellent parfois les considérations de la ‘nouvelle rhétorique’, la relation entre l'éthique et la rhétorique y est envisagée d'une manière toute différente. Pour les auteurs médiévaux la rhétorique est une science auxiliaire de l'éthique : elle sert de liaison entre la théorie et la pratique. Dans la partie théorétique de l'éthique la logique ‘générale’ reste en vigeur. Ce n'est que pour mettre en pratique les règles et valeurs qui ont été ‘démontrées’ par la théorie qu'on a recours à la technique persuasive et sa logique ‘spéciale’. La rhétorique n'a donc qu'une fonction subsidaire. On retrouve la même conception au début des temps modernes chez Francis Bacon qui attribue à la rhétorique la fonction d'appliquer le dictamen rationis à l'imagination pour exciter ainsi la volonté. Une tout autre conception est défendue par l'humaniste Lorenzo Valla qui essaie de réintégrer l'argumentation morale dans le discours rhétorique où elle trouve sa place originaire. Notre propre point de vue est développé en confrontation avec Aristote, de qui nous avons hérité le projet d'une ‘science pratique’ et l'ambiguité qui en est inhérente 1° La rhétorique présuppose l'éthique. 2° L'éthique qui se veut epistème, ne relève pas de la rhétorique qui n'est qu'une technè. Elle se présente comme une science à caractère dialectique. 3° Les difficultés arrivent dès qu'on exalte la fonction pratique de cette science (cf. récemment R. Hare). Dès que l'éthique veut être efficace dans la vie concrète, elle devient une argumentation qui relève plutôt du discours épidectique (Weltanschauung). Notre société, en pleine crise morale, a certainement besoin d'un tel discours qui essaie d'intensifier l'adhésion à des valeurs morales. Mais il nous semble qu'il reste à côté d'un tel discours - en pleine expansion des nos jours - une place bien discrète pour une reflection critique qui en analyse les raisons : qui n'est pas inutile, bien que peu efficace.

A partir de una consideración sobre la incidencia del lenguaje en la tarea filosófica, en especial sobre la filosofía del lenguaje, examinaré, en primer lugar, los alcances de las caracterizaciones más relevantes: análisis lingüístico y semiología, para cotejarlos con los desarrollos de la hermenéutica contemporánea. Procuraré mostrar que las consecuencias sobre los rendimientos del lenguaje son de mayor radicalidad en el caso de esta última, por la específica atención que presta a las diversas modalidades de experiencia lingüística. Una vez reconocida (...) la especificidad de ese enfoque, distinguiré los aportes de las tres versiones que se destacan en el panorama hermenéutico actual: la ontológica, la crítica y la analógica. Finalmente, presentaré a la tercera en relación de comparación con las anteriores como una contribución de gran poder heurístico para revisar las consecuencias generales del giro lingüístico.

La metodología teológico-pastoral, que configuró no solo los textos sino la dinámica de trabajo de Medellín, tuvo en la década del sesenta importantes desarrollos y debates. La presente contribución se concentra, particularmente, en una crítica radical a dicha Conferencia formulada entonces por Eduardo Briancesco. Primero, presenta las objeciones del teólogo argentino, quien afirma que hay en Medellín una exaltación indebida de lo empírico. En segundo lugar, el artículo realiza una evaluación de la posición del autor, prestando atención, de forma particular, (...) a algunos aspectos importantes del estado de la cuestión en el debate metodológico de entonces. De esta manera se contextualiza mejor la crítica y también se comprenden más adecuadamente algunos logros y limitaciones de la obra de Medellín desde el punto de vista de la metodología teológica.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hispanic Philosophy in the Age of Discovery ed. by Kevin WhiteIván JaksicKevin White, editor. Hispanic Philosophy in the Age of Discovery. Washington, DC: Catholic University of America Press, 1997. Pp. xv + 326. Cloth, $59.95.The quincentennial of what has been termed the “encounter” between Europeans and Indians in the New World in the late fifteenth century furnished the occasion for much denunciation of the evils inflicted by greedy (...) intruders on the indigenous population and their environment. Many a conference was convened to reflect on such [End Page 463] events from the perspective of what appeared to be a consensus on the ultimately negative effects of European discovery, conquest, and colonization. In this context, it is quite remarkable that a conference on Hispanic philosophy in the age of discovery should have been convened to examine the philosophical figures and treatises of the era. As it turns out, this volume represents probably one of the most enduring outcomes of the myriad activities of 1992. This is a volume that ranges widely into the philosophical world of the period, brings to light the richness and significance of philosophers and their work, and provides a coherent and consistently well-researched set of essays.The volume consists of fifteen essays divided into five parts. Part I consists of one essay by Jorge J. E. Gracia which offers a wide panorama of Hispanic philosophy from 1500 to 1650, as well as a lucid interpretation of the historical reasons why Hispanic philosophy seems to have reached a dead end in the context of modern European philosophy, and suffered the neglect of intervening centuries. Part II consists of one essay by Mauricio Beuchot on discussions concerning the conquest of Mexico; two essays by John Doyle and Marcelo Sánchez-Sorondo on the work of Francisco de Vitoria; and two essays on the celebrated dispute between Juan Ginés de Sepúlveda and Bartolomé de las Casas in 1550–51, the first by Eduardo Andújar and the second by Rafael Alvira and Alfredo Cruz. Part III includes essays by William Wallace on Domingo de Soto and Galileo’s science; Juan Antonio Widow on the economic thought of the Spanish Scholastics; Jean de Groot on the mysticism of Teresa de Avila; Yves Floucat on St. John of the Cross, and Mirko Skarica on the problem of future contingents. Part IV includes three essays by Norman Wells, Stephen Menn, and Carlos G. Noreña on the works of Francisco Suárez, probably the best-known Spanish thinker of the period. The volume closes with Part V, which has a long essay by John Deely on John Poinsot’s doctrine of signs.A volume of this scope and nature is bound to contain some overlap and repetition, as is the case with the pieces concerning the Las Casas-Sepúlveda debate. And yet these essays read well because the authors seriously undermine the conventional treatment of Sepúlveda as the hawkish defender of Indian slavery, and place him in the context of a larger Renaissance view of non-European peoples. Las Casas, in the view of the authors, had a great deal more in common with his opponent than the historiography has thus far suggested. In other sections of the volume, the variety of approaches and subjects on the part of the contributors challenges the reader to constantly shift grounds. Part III, for instance, takes us from the disquisitions on the velocity of falling bodies to the moral aspects of economic thought, and to the meaning of mystical theology. Fortunately, the competence of the researchers makes all individual pieces worthwhile even if this particular reviewer would have been somewhat more stringent with the space allotted to make a point.Contributors to this book leave no doubt as to the importance of their subjects, and yet they resist the temptation of exaggerating the extent of the influence of many of the Spanish authors on other European thinkers. Indeed, the essay by Norman Wells shows that while one must consider the linkages between Suárez and Descartes, there is [End Page 464] no reason to believe that the latter made Suárez’s position on the moderni...

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.

The notion of stimulus meaning, a key notion for Quine's Indeterminacy of Translation thesis, has undergone an essentiaJ change fi'om the beginning of the nineties. Then, this essay offers an expository work oj this change (its origin and motivations) and its final result. Th~ main aim of this essay is to show the validity of the reasons that forced Quine to modify his stimulus meaning notion and the failure of its substitutes (global stimulus, stimulus range, and perceptual similarity) to solue (...) the problems they were thought to give an account of. Moreover, these new notions make the Indeterminacy Thesis, mainly the Inscrutability of Reference Thesis, face new problems and, if I'm right, unsolvable ones. (shrink)

Este artículo regresa al clásico texto de Freud Das Unheimliche para tratar de exhibir la dimensión productiva y la perspectiva de futuro que le son inherentes. Para ello, se visitan las propuestas del artista Mike Kelley y del filósofo Giorgio Agamben que tratan de ilustrar plásticamente las características de esta noción. Se examinan, a continuación, las tesis freudianas sobre el manejo de los significantes en un marco de angustia unheimlich, esto es, de pérdida súbita de las referencias habituales. Se termina (...) defendiendo que es la apuesta de vanguardia del futurismo, de la que el texto de Freud sería epitafio, la que mejor permite exhibir la importancia crucial del término Unheimliche para la ontología psicoanalítica.
