In the Metaphysics of the Shifâ Avicenna distinguishes three ways in which universals are said. The second sense is puzzling since Avicenna explains that universals are said of what it is permissible to say of many, even if it is not a condition that these many should exist in actuality, and he illustrates this kind of universals with the “heptagonal house”. In its nature this universal can be said of many, but it does not follow necessarily that these many (...) must exist -not even one of them. This second case deals with a less common type of universal, since such universals may have either only one instantiation or even none at all. The example of the heptagonal house is not traditional, as Greek sources, such as Porphyry and Simplicius, use the phoenix instead. In this paper Thérèse-Anne Druart explores in depth the use of this particular illustration, namely, the “heptagonal house”. (shrink)

Imagination has received a great deal of attention in different fields such as psychology, philosophy and the cognitive sciences, in which some works provide a detailed account of the mechanisms involved in the creation and elaboration of imaginary worlds. Although imagination has also been formalized using different logical systems, none of them captures those dynamic mechanisms. In this work, we take inspiration from the Common Frame for Imagination Acts, that identifies the different processes involved in the creation of imaginary worlds, (...) and we use it to define a dynamic formal system called the Logic of Imagination Acts. We build our logic by using a possible-worlds semantics, together with a new set of static and dynamic modal operators. The role of the new dynamic operators is to call different algorithms that encode how the formal model is expanded in order to capture the different mechanisms involved in the creation and development of imaginary worlds. We provide the definitions of the language, the semantics and the algorithms, together with an example that shows how the model is expanded. By the end, we discuss some interesting features of our system, and we point out to possible lines of future work. (shrink)

Se analiza la situación paradójica que presenta la secularización en América reconstruida por Tocqueville. Teniendo presente este postulado, mostraremos la ruptura que se establece con respecto a la Ilustración en el tema de la secularización, en aras de descubrir una nueva variante de la crisis de la filosofía que permaneces vinculada con la nueva estructura organizacional de las sociedades democráticas modernas. Asimismo, mostraremos cómo el perfil liberal de Tocqueville se muestra superador de las versiones eurocéntricas en el tema de la (...) crisis de la filosofía, en la medida de que su devaluación no procede únicamente de anomalías metodológicas, sino del cambio de autoridad intelectual operado por la secularización para empoderar a la opinión pública. Por esta razón, procederemos finalmente a mostrar en qué medida la novedad de la paradoja de la secularización en América reconstruida por Tocqueville, define la crisis de la filosofía como asunto del futuro en virtud de la serie de problemas inéditos que demanda satisfacer.

This essay examines Arendt’s descriptions of “Hottentots” in The Origins of Totalitarianism, especially the comparisons and contrasts she frequently draws between Hottentots and other peoples. In particular, Arendt highlights dehumanization of presumptively “civilized” people in comparing them to African “savages.” Close reading of such analogies demands that we look beyond the racial explanations that other scholars have offered and focus instead on how Arendt’s conception of humanity is bound up with a specific sense of culture that is antiprimitivist—exclusive of peoples (...) without history, primitives. Analysis of her moral anthropology uncovers the Cape Colony discourses and postenlightenment German philosophical supports that inform her antiprimitivism. However, Arendt’s antiprimitivism may not remain confined to Origins. In later essays, Arendt analyzes the various aspects of culture in instructive ways.Yet she also synthesizes culture concepts into a schema that introduces problems for her. (shrink)

In this paper, we review three influential theories of imagination in order to understand how the dynamics of imagination acts could be modeled using formal languages. While reviewing them, we notice that they are not detailed enough to account for all the mechanisms involved in creating and developing imaginary worlds. We claim those theories could be further refined into what we call the Common Frame for Imagination Acts, which defines a framework that can be used to study the dynamics of (...) imagination using formal languages, and we support our claim by showing how the framework allows to model certain imagination acts step by step. Then, we introduce the Rhombus of Imagination, which is a visual tool that can be used in conjunction with our framework to study the procedural structure of different kinds of imagination acts and identify their dynamic properties.

Se justifican tres tesis. Primera, el sentido mítico-religioso tradicional de la justicia como castigo de la [palabra en griego] quedó desacreditado durante la Guerra del Peloponeso, como bien lo muestra Tucídides. Segunda, en tiempos de Aristóteles, tal sentido ya habría desaparecido en favor de un nuevo paradigma basado en el concepto de [palabra en griego]. Tercera, la obra de Platón constituye uno de los últimos intentosde recuperar ese sentido mítico-religioso tradicional tratando de interpretar la Guerra del Peloponeso a través del (...) mecanismo del castigo de la [palabra en griego] . --- “The notion of ‘hybris’ in Plato’s Critias”. The following theses are basically justified: (1) the traditional mythical-religious sense of justice as punishment of the [greek word] was discredited during the Peloponnesian War, as Thucydide shows. (2) In times of Aristotle such a sense had already disappeared in favour of a new paradigm based on the concept of [greek word]. (3) Plato’s work constitutes one of the last attempts to recover the traditional mythical-religious sense trying to interpret the Peloponnesian War through the mechanism of punishment of the [greek word].

Una de las cuestiones más llamativas de las obras de Platón y Aristóteles estriba en su silencio acerca de la historia. Leyeron y criticaron a físicos, filósofos, matemáticos, biólogos, poetas, retóricos, políticos, etc. Sin embargo, sus citas a propósito de los historiadores de su momento cabrían en una cuartilla. En este breve artículo tratamos de ofrecer una explicación a propósito de tal omisión. Así mismo, aprovechamos para ofrecer una razón del Menéxeno y aportar una confirmación de las razones que condujeron (...) a L. Edelstein a cuestionar la autenticidad de las cartas séptima y octava atribuidas a Platón. One of the most showy questions about the works of Plato and Aristotle rests on them silence brings over of the history. They read and criticized physicists, philosophers, mathematicians, biologists, poets, rhetorical, political, etc. Nevertheless, their appointments about the historians of that moment would fit in a sheet of paper. In this brief article we try to offer an explanation about such an omission. Likewise, we are useful to offer a reason of the Menexenus and to contribute a confirmation of the reasons that L. Edelstein led to questioning the genuineness of seventh and eighth letters attributed to Plato. (shrink)

A pesar de la relevancia que ganó el pensamiento de Jean-François Lyotard con la publicación de La Condition postmoderne (1979), solo un pequeño número de publicaciones académicas han abordado sus primeras propuestas en el campo de la estética. Este artículo pretende contribuir a la tarea de enmendar semejante error. Para ello se propone una aproximación general y sistemática a sus primeros usos del concepto de figura, comenzando por sus precedentes e influencias y concluyendo con la afirmación de que la estética (...) de Lyotard no expone una mera filosofía de las artes o una filosofía de la percepción, sino una auténtica ontología. Para facilitar la comprensión de esta cuestión, se abordarán algunos de sus conceptos más complejos, como el de figura-matriz, y se harán pequeñas aproximaciones a la producción de artistas como Joan Fontcuberta y Peter Tscherkassky, cuya obra explicita el tema central de este artículo: la poética, la política y la ontología de la figura.

The concept of will to power is one of the most important Nietzsche’s theories, that deals with the capacity of a person to face death and the thought of his own sacrifice without any fear, in order to obtain one’s self-overcoming. The so called will to wreck is the most powerful objectification of will to power, and it is deep-rooted in European society, especially German popular ideology. Actually, it is possible to find this conception of will to wreck in connection (...) with will to power in Nibelungenlied, the greatest Nordic poem of 13th century, and, years and years later, in Nazi ideology (and of course Nietzsche himself), as a proof of the temporal continuity of this particular philosophy. A philosophy which is probably part of our psychology, and which is not likely to be easily forgotten though its terrible, destructive power. (shrink)

Imagining is something we use everyday in our lives and in a wide variety of ways. In spite of the amount of works devoted to its study from both psychology and philosophy, there are only a few formal systems capable of modelling it; besides, almost all of those systems are static, in the sense that their models are initially predefined, and they fail to capture the dynamic process behind the creation of new imaginary scenarios. In this work, we review some (...) influential theories of imagination and use their insights to distil an algorithm describing such process. Then, we use this algorithm to define a dynamic logical system built upon on a single-agent epistemic logic that provides the necessary tools to capture how the agent voluntarily creates new imaginary worlds; in other words, our system allows the model to be expanded dynamically at any time as a result of the agent performing an act of imagination. Furthermore, we provide an axiomatization and prove that the system is sound and complete. (shrink)
