Os prólogos dos comentários de Tomás de Aquino às obras de Aristóteles são de suma importância, porque neles o autor apresenta o que se poderia denominar “o marco conceptual” do trabalho que está empreendendo. No caso do Comentário à Política, o conceito fundamental é o conceito de natureza. A afirmação de que existe uma “imitação da natureza” significa, para Tomás, muito mais do que representou para seus antecessores. PALAVRAS-CHAVE – Tomás de Aquino. Comentário. Política. Natureza. Imitação. ABSTRACT The prologs of (...) Thomas Aquinas to the works of Aristotle are of main importance, because in these prologs the author presents what could be called “the conceptual mark” of the tasks he is undertaking. In the case of the Comments to the Politics, the fundamental concept is the concept of nature. The statement that there is an “imitation of nature” means, for Thomas, much more that it had represented for his antecessors. KEY WORDS – Thomas Aquinas. Comment. Politics. Nature. Imitatio.

Propósito: la adecuación del esfuerzo terapéutico es una decisión clínica basada en la evidencia que pretende evitar la futilidad médica. Se han señalado diferentes factores que pueden influir en esta toma de decisiones los cuales se relacionan con el paciente, el profesional médico que toma de las decisiones, barreras del sistema, cultura y economía, entre otros. El presente estudio pretende identificar aquellos factores que influyen en los médicos especialistas que laboran en la institución referente del cáncer en Colombia, a fin (...) de planear acciones que mejoren el abordaje de la toma de decisiones con respecto a la adecuación del esfuerzo terapéutico en pacientes con cáncer. Metodología: diseño cualitativo basado en 13 entrevistas en profundidad a médicos especialistas del Instituto Nacional de Cancerología de Colombia. Resultados: participaron 3 mujeres y 10 hombres, con un promedio de edad de 36 años, 7 pertenecientes a la especialidad de oncología de adultos, 2 a oncohematología pediátrica, 1 a cuidados intensivos de adultos y 3 a cuidados intensivos pediátricos. Los factores hallados se agruparon en cuatro categorías: 1) conocimiento, 2) aspectos relacionados con la toma de decisiones, 3) quién decide, 4) tipo de decisión que se toma; a su vez, estas categorías se agruparon en temas que hacen alusión a los factores que influyen en la toma de decisiones de los especialistas para adecuar los esfuerzos terapéuticos. Conclusión: la adecuación de los esfuerzos terapéuticos es importante para evitar procedimientos médicos fútiles que prolonguen el sufrimiento. Se evidenciaron algunos factores que influyen en la toma de decisiones de los especialistas: falta de preparación de los profesionales de salud en el tema de toma de decisiones al final de la vida, uso reducido de escalas que permitan mejorar la información del pronóstico y desconocimiento sobre voluntades anticipadas; estos son algunos de aquellos factores que deben fortalecerse para generar acciones que mejoren el abordaje de esta temática.

Cuando bioética y derecho hacen frente a un hard problem, el resultado suele ser la diversidad de posiciones doctrinales, la disparidad de soluciones entre los distintos sistemas jurídicos y, a nivel supranacional, la ausencia de regulación o la adopción de una extremadamente restrictiva. Tales diferencias pueden rastrearse hasta las tradiciones culturales de las que proceden. Este trabajo toma a la mejora genética germinal humana como un caso de cómo las diferencias entre las tradiciones culturales atlántica y mediterránea pueden obstaculizar la (...) consecución de un bioderecho internacional. Para la biocuestión elegida, las discrepancias se manifiestan en desiguales concepciones relativas a dos ejes temáticos: la naturaleza y el cuerpo humano. Tras su análisis, se proponen algunas líneas de acción encaminadas a la superación de dichas barreras y la obtención de un bioderecho común para la edición genética perfectiva de la línea germinal humana.

RESUMEN Las tensiones y los vínculos posibles entre razón y violencia son un problema mayor para la filosofía. La obra de Eric Weil se consagra precisamente al análisis de las figuras históricas de dicha tensión, y su obra mayor, Logique de la Philosophie, desarrolla lo fundamental de dicho propósito. Se analiza la manera como Weil, desde la categoría de la acción -última categoría concreta de la filosofía-, en vínculo con las categorías precedentes (absoluto, obra, finito) y con las categorías formales (...) (sentido y sabiduría), enfrenta este desafío siempre nuevo para la filosofía. ABSTRACT The tensions and potential links between reason and violence are a significant philosophical problem. Eric Weil's systematic work, as well as his numerous articles and lectures, is dedicated to the analysis of the historical figures of such tensions. His major work, Logique de la Philosophie, develops that objective. The article analyzes how Weil faces this always new challenge for philosophy, on the basis of the category of action -the last concrete category of his philosophy-, together with the preceding categories (absolute, unmediated particular, finite) and the formal categories (meaning and wisdom).

When people understand a counterfactual such as “if the flowers had been roses, the trees would have been orange trees,” they think about the conjecture, “there were roses and orange trees,” and they also think about its opposite, the presupposed facts. We test whether people think about the opposite by representing alternates, for example, “poppies and apple trees,” or whether models can contain symbols, for example, “no roses and no orange trees.” We report the discovery of an inference‐to‐alternates effect—a tendency (...) to make an affirmative inference that refers to an alternate even from a negative minor premise, for example, “there were no orange trees, therefore there were poppies.” Nine experiments show the inference‐to‐alternates effect occurs in a binary context, but not a multiple context, and for direct and indirect reference; it can be induced and reduced by prior experience with similar inferences, and it also occurs for indicative conditionals. The results have implications for theories of counterfactual conditionals, and of negation. (shrink)

The work of Gloria Anzaldúa has not typically been read in concert with utopian studies. Much of her writing, however, offers a rich resource for utopian critique. This is a significant omission given that much of Latin@ speculative fiction has been deemed inherently utopic. Latin@futurism is a field of inquiry by which to focus on the utopian as a broader category of visionary, speculative forms. Anzaldúa draws on techniques of defamiliarization to usher a change of consciousness in the reader, exemplified (...) by her theories of conocimiento, el cenote, and nepantla. This article discusses Anzaldúa's theory of el cenote as a powerful heterotopic space of renewal and transformation in Yuri Herrera's novel Signs Preceding the End of the World. Anzaldúa's theories of conocimiento and nepantla flesh out culminating aspects of borderlands dreaming in the novel that connect to a discourse of apocalypse and its relationship to historical renewal and social justice.

We examine two competing effects of beliefs on conditional inferences. The suppression effect occurs for conditionals, for example, “if she watered the plants they bloomed,” when beliefs about additional background conditions, for example, “if the sun shone they bloomed” decrease the frequency of inferences such as modus tollens (from “the plants did not bloom” to “therefore she did not water them”). In contrast, the counterfactual elevation effect occurs for counterfactual conditionals, for example, “if she had watered the plants they would (...) have bloomed,” when beliefs about the known or presupposed facts, “she did not water the plants and they did not bloom” increase the frequency of inferences such as modus tollens. We report six experiments that show that beliefs about additional conditions take precedence over beliefs about presupposed facts for counterfactuals. The modus tollens inference is suppressed for counterfactuals that contain additional conditions (Experiments 1a and 1b). The denial of the antecedent inference (from “she did not water the plants” to “therefore they did not bloom”) is suppressed for counterfactuals that contain alternatives (Experiments 2a and 2b). We report a new “switched‐suppression” effect for conditionals with negated components, for example, “if she had not watered the plants they would not have bloomed”: modus tollens is suppressed by alternatives and denial of the antecedent by additional conditions, rather than vice versa (Experiments 3a and 3b). We discuss the implications of the results for alternative theories of conditional reasoning. (shrink)

We report five experiments showing that the activation of the end-terms of a syllogism is determined by their position in the composite model of the premises. We show that it is not determined by the position of the terms in the rule being applied (Ford, 1994), by the syntactic role of the terms in the premises (Polk & Newell, 1995; Wetherick & Gilhooly, 1990), by the type of conclusion (Chater & Oaksford, 1999), or by the terms from the source premise (...) (Stenning & Yule, 1997). In our first experiment we found that after reading a categorical premise, the most active term is the last term in the premise. In Experiments 2, 3, and 4 we demonstrated that this pattern of activity is due to the position of the concepts in the model of the premises, regardless of the delay after reading the premises (150 or 2000 msec) or the quantity of the quantifiers (universal or existential). The fifth experiment showed that the pattern switches around after participants evaluate a conclusion. We propose that the last element in the model maintains a higher level of activity during the comprehension process because it is generally used to attach the incoming information. After this process, the first term becomes more active because it is the concept to which the whole representation is referred. These results are predicted by the mental model theory (Johnson-Laird & Byrne, 1991), but not by the verbal reasoning theory (Polk & Newell, 1995), the graphical methods theory (Yule & Stenning, 1992), the attachment-heuristic theory (Chater & Oaksford, 1999), or the mental rules theory (Ford, 1994).

Si la virtus de la Antigüedad era la fuerza, la valentía y el coraje, y en la modernidad la diligencia, el trabajo, el mérito y el esfuerzo, actualmente se ha instalado la commoditas, una suerte de pseudovirtud nihilista que reivindica la ociosidad, el igualitarismo radical y el entretenimiento. La sociedad contemporánea posmoderna ha superado tanto la metafísica filosófica grecorromana como la teología cristiana, tanto el racionalismo y el empirismo ilustrado como el idealismo romántico decadentista y el positivismo materialista, y ha (...) entrado en una suerte de fin de la historia de nihilismo lúdico autocomplaciente y autosatisfecho. Concluimos que la commoditas está para quedarse y reconfigurará la naturaleza del ser humano en función de una nueva mentalidad que empalidece a la tradición hasta prácticamente anularla. (shrink)

In the development of Roman Catholic social thought from the teachings of the scholastics to the modern social encyclicals, changes in normative economics reflect the transformation of an economic terrain from its feudal roots to the modern industrial economy. The preeminence accorded by the modern market to the allocative over the distributive function of price broke the convenient convergence of commutative and distributive justice in scholastic just price theory. Furthermore, the loss of custom, law, and usage in defining the boundaries (...) of economic behavior led to a depersonalization of economic relationships that had previously provided effective informal means of protecting individual well-being. Hence, recent economic ethics has had to look for nonprice, nonmarket mechanisms for distributive justice. This is reflected, for example, in the shift in attitude from the medieval antipathy toward unions to the contemporary defense of organized labor on moral grounds. (shrink)

Drawing could be considered the oldest known art form. However, art and its understanding has come to evolve so much that it has derived a multitude of forms that are almost unclassifiable today. The aesthetic discourses of the public, social and political have also been prejudiced and their true essence has been altered. In the present research work, we explore a series of artists who work with art as a language and tool for change and improvement of public life in (...) general. We analyse the messages they address, the aesthetics and material form they use, the methodologies they practice or the social changes they cause. In this regard, through a selection of contemporary projects, we can identify more effective representative artistic characteristics that are consistent with our current world. In conclusion, we emphasize that the practice of public art is more significant and necessary than it seems. (shrink)

Since the very beginnings of Philosophy, the multifaceted problem of time has constituted one of the central concerns of philosophers and other thinkers. From pre-Socratic speculation to Platonic metaphysics, from St. Augustine to the medieval theologians, meditation upon time was unceasing, and the issue became yet more acute with the development of modern philosophy following Descartes One might summarize the slow evolution of Western thought in this area as follows: time began in Greek philosophy as a property of the world, (...) was later referred basically to human beings, and in the twentieth century has recovered its cosmic nature thanks to contemporary physics .It is of course beyond the reach of a single article to tackle the problem of time in its entirety. Here, I shall concentrate on a single very specific aspect: the definition of the past and the question of whether the past has any explicative value. It is largely on the answer to this question that the possibility of maintaining the coherent identity of history as a branch of knowledge depends. (shrink)

Resumen Esta investigación aborda el “texto autoetnográfico” entendido como una indagación epistémica que realiza un sujeto respecto de procesos vitales que busca dar sentido. Estos textos se caracterizan por integrar diferentes voces o puntos de vista que crean y representan un significado moral y, que, en el marco de una perspectiva pos/decolonial, actúan combinando o infiltrando elementos y conceptos indígenas para crear autorrepresentaciones destinadas a intervenir en los modos metropolitanos de comprensión y representación del “otro”.Desde este punto de vista, este (...) trabajo sostiene que estos tipos de textos emergen como una nueva estrategia del discurso artístico y literario indoamericano en respuesta al imaginario colonial, cuyos mecanismos de reificación se invierten mediante complejos procesos retóricos, desestabilizando los significados legitimados por la institucionalidad colonial. Para observar este proceso se analiza el discurso visual y poético del pueblo mapuche, abriendo una discusión acerca de los nuevos procesos de representación del arte indígena actual.This investigation addresses the “autoethnographic text”, understood as an epistemic enquiry that a subject provides about vital processes that it seeks to give meaning to. These texts are characterized by the integration of different voices and/or points of view, that create and represent a moral meaning and that, within the framework of a post/decolonial perspective, act by combining or infiltrating indigenous elements and concepts to create self-representations designed to intervene in the metropolitan modes of understanding and representation of the “other”. From this point of view, this work maintains that these types of texts emerge as a new strategy of Indo-American artistic and literary discourse in response to the colonial imaginary, whose mechanisms of reification are reversed by complex rhetorical processes, destabilizing the meanings legitimized by colonial institutionality. In order to observe this process, the visual and poetic speech of the Mapuche people is analyzed, opening up a discussion about the new processes of representation of current indigenous art.

Resumen: La impronta colonial en el pueblo mapuche llevó a gran parte de sus producciones culturales al borde de la extinción; una de ellas es el tallado monumental en madera, vinculado a procesos ceremoniales en la cultura ancestral. No obstante, desde la década de los noventa, este reaparece junto con los procesos de recuperación y fortalecimiento de la identidad cultural, y adquiere una rápida expansión en el antiguo territorio mapuche dinamizando la frontera política y cultural de este pueblo bajo dos (...) vertientes, como práctica cultural tradicional o como expresión de un arte moderno mayoritariamente urbano. En este marco, este trabajo indaga cómo la instalación del tallado monumental resignifica los espacios urbanos y rurales del Güllumapu. Se sostiene que estas producciones culturales actúan semiotizando el espacio de contacto cultural, refundando el antiguo wallmapu o territorio mapuche, proceso que se realiza al inscribir una fuerte carga simbólica que convoca un nuevo sentido del tiempo-espacio histórico en el territorio mediante una “producción de localidad”, articulando categorías de identidad cultural y nacional, y colaborando en la recuperación de las fronteras al construir una narrativa de la identidad cultural y nacional en un contexto adverso.: The colonial stamp on the Mapuche people led their cultural productions in large part to the brink the extinction. One of these is monumental wood carving, linked to ceremonial processes in the ancestral culture. However, since the 1990s, this has reappeared together with the processes of recovery and strengthening of the cultural identity, and has rapidly expanded into the old Mapuche territory, invigorating the political and cultural border of this people with two main focuses: as a traditional cultural practice or as an expression of mainly urban modern art. In this framework, this study investigates how the installation of monumental carving is redefining the urban and rural spaces of Güllumapu. It is maintained that these cultural productions act by semiotizing the cultural contact space, refounding the old wallmapu or Mapuche territory, a process done by inscribing a strong symbolic power that summons a new sense of the historical time-space in the territory through a “production of place”, articulating categories of cultural and national identity and collaborating in the recovery of the borders by constructing a narrative of the cultural and national identity in an adverse context.

We performed a critical review of the historiographical studies on biogeography. We began with the pioneering works of Augustin and Alphonse de Candolle. Then, we analyzed the historical accounts of biogeography developed by (1) Martin Fichman and his history on the extensionism-permanentism debate; (2) Gareth Nelson and his critique of the Neo-Darwinian historiography of biogeography; (3) Ernst Mayr, with his dispersalist viewpoint; (4) Alan Richardson, who wrote a microhistory on the biogeographic model constructed by Darwin; (5) Michael Paul Kinch and (...) the ideas discussed in the 19th century about the geographical distribution of living beings; (6) Janet Browne, who highlighted the importance of the pre-Darwinian naturalists; (7) Peter Bowler, who focused mainly on the influence of paleontology on biogeography; (8) James Larson, who looked into the practices of the naturalists of Northern Europe in the late 18th century; and (9) Malte Ebach, who like Larson, was more interested in analysing the practices rather than the ideas of naturalists who studied the geographical distribution of organisms. Finally, these works are compared with each other. There has not been a dominant paradigm in the construction of historical narratives of biogeography; however, they provide a useful context for understanding problems of biogeography that continue to be debated to this day.

Many philosophers believe that our ordinary English words man and woman are “gender terms,” and gender is distinct from biological sex. That is, they believe womanhood and manhood are not defined even partly by biological sex. This sex/gender distinction is one of the most influential ideas of the twentieth century on the broader culture, both popular and academic. Less well known are the reasons to think it’s true. My interest in this paper is to show that, upon investigation, the arguments (...) for the sex/gender distinction have feet of clay. In fact, they all fail. We will survey the literature and tour arguments in favor of the sex/gender distinction, and then we’ll critically evaluate those arguments. We’ll consider the argument from resisting biological determinism, the argument from biologically intersex people and vagueness, the argument from the normativity of gender, and some arguments from thought experiments. We’ll see that these arguments are not up to the task of supporting the sex/gender distinction; they simply don’t work. So, philosophers should either develop stronger arguments for the sex/gender distinction, or cultivate a variety of feminism that’s consistent with the traditional, biologically-based definitions of woman and man.

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong, or using a method that wouldn't have given you this belief had it been false. Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist project from Carlotta Pavese (...) and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

Many contemporary epistemologists hold that a subject S’s true belief that p counts as knowledge only if S’s belief that p is also, in some important sense, safe. I describe accounts of this safety condition from John Hawthorne, Duncan Pritchard, and Ernest Sosa. There have been three counterexamples to safety proposed in the recent literature, from Comesaña, Neta and Rohrbaugh, and Kelp. I explain why all three proposals fail: each moves fallaciously from the fact that S was at epistemic risk (...) just before forming her belief to the conclusion that S’s belief was formed unsafely. In light of lessons from their failure, I provide a new and successful counterexample to the safety condition on knowledge. It follows, then, that knowledge need not be safe. Safety at a time depends counterfactually on what would likely happen at that time or soon after in a way that knowledge does not. I close by considering one objection concerning higher-order safety.
