This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

Este artigo busca encontrar na teoria crítica da racionalidade moderna de Jürgen Habermas (1929-) elementos de uma paideia. O primeiro tópico lança o substrato epistemológico sobre a existência das racionalidades estratégica e comunicativa. O segundo, afirma que o desengate entre o sistema e o mundo da vida, e a colonização deste por aquele, causam as patologias modernas e colaboram para a formulação de pedagogias coordenadas pela ação estratégica. O terceiro, propõe que o reacoplamento do sistema ao mundo vivido proporciona que (...) todas as dimensões da existência humana sejam orientadas pela ação comunicativa, na qual se encontram os traços de uma paideia emancipadora e revolucionária.

En la historia aparece el tema de los derechos humanos sólo en el siglo XX. Ninguna reflexión filosófica se había preocupado por la cuestión del ser humano como sujeto de unos derechos inherentes a su propio ser. La filosofía le había reconocido el derecho a la razón, Occidente y su tradición cristiana le había reconocido su derecho a la eternidad y dignidad de hijo de Dios para otorgarle la inmortalidad. Ahora bien, ¿por qué en esta tradición no aparece el hombre (...) como poseedor de unos derechos básicos propios, independientes de su condición social, política y económica? Derechos que le fueran concedidos por el solo hecho de ser hombre. Los derechos humanos adquieren su fundamento metafísico sólo a partir de la realidad histórica del hombre y de allí se evidencia su estatuto epistemológico. Solamente la historicidad del hombre a partir de las raíces en la materialidad le da sentido al derecho humano como tal. Es a partir del hombre como ser material y propio de una realidad histórica que encuentra su carta de ciudadanía en el discurso por los derechos humanos. Y en eso, Ellacuría tendrá mucho que decir.

> Wealthy nations must do much more, much faster. The United Nations General Assembly in September 2021 will bring countries together at a critical time for marshalling collective action to tackle the global environmental crisis. They will meet again at the biodiversity summit in Kunming, China, and the climate conference 26) in Glasgow, UK. Ahead of these pivotal meetings, we—the editors of health journals worldwide—call for urgent action to keep average global temperature increases below 1.5°C, halt the destruction of nature (...) and protect health. Health is already being harmed by global temperature increases and the destruction of the natural world, a state of affairs health professionals have been bringing attention to for decades.1 The science is unequivocal; a global increase of 1.5°C above the preindustrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.2 3 Despite the world’s necessary preoccupation with COVID-19, we cannot wait for the pandemic to pass to rapidly reduce emissions. Reflecting the severity of the moment, this editorial appears in health journals across the world. We are united in recognising that only fundamental and equitable changes to societies will reverse our current trajectory. The risks to health of increases above 1.5°C are now well established.2 Indeed, no temperature rise is ‘safe’. In the past 20 years, heat-related mortality among people aged over 65 has increased by more than 50%.4 Higher temperatures have brought increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality.5 6 Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities and those with underlying health problems.2 4 Global heating is also contributing to the decline in ….

In this article, we outline a simple and intuitively appealing procedure to derive default priors. The main idea is to regard the choice of such a prior as a formal Bayesian decision problem. We also discuss Jeffreys prior and more generally the reference prior of Bernardo (J R Stat Soc B 41:113–147, 1979) from this standpoint.

Los autores se preguntan por el aporte real de los biocombustibles a la solución de los problemas ambientales. Después de analizar las actuales formas de producción en Brasil, sostienen que la expansión de éstos presionará indirectamente hacia la deforestación, contribuyendo así aún más al calentamiento global. Señalan lo falaz del discurso que justifica la expansión de los biocombustibles por su aporte a la generación de empleo. Sostienen que es fundamental incorporar los requerimentos de sostenibilidad en la cadena de producción para (...) garantizar competitividad a los países potencialmente exportadores, pero que aún así esa solución es limitada ya que todas las energías alternativas y renovables juntas, no suplirían las proyecciones del patrón de consumo mundial.

This introduction to the Common Knowledge symposium titled “Comparative Relativism” outlines a variety of intellectual contexts where placing the unlikely companion terms comparison and relativism in conjunction offers analytical purchase. If comparison, in the most general sense, involves the investigation of discrete contexts in order to elucidate their similarities and differences, then relativism, as a tendency, stance, or working method, usually involves the assumption that contexts exhibit, or may exhibit, radically different, incomparable, or incommensurable traits. Comparative studies are required to (...) treat their objects as alike, at least in some crucial respects; relativism indicates the limits of this practice. Jensen argues that this seeming paradox is productive, as he moves across contexts, from Lévi-Strauss's analysis of comparison as an anthropological method to Peter Galison's history of physics, and on to the anthropological, philosophical, and historical examples offered in symposium contributions by Barbara Herrnstein Smith, Eduardo Viveiros de Castro, Marilyn Strathern, and Isabelle Stengers. Comparative relativism is understood by some to imply that relativism comes in various kinds and that these have multiple uses, functions, and effects, varying widely in different personal, historical, and institutional contexts that can be compared and contrasted. Comparative relativism is taken by others to encourage a “comparison of comparisons,” in order to relativize what different peoples—say, Western academics and Amerindian shamans—compare things “for.” Jensen concludes that what is compared and relativized in this symposium are the methods of comparison and relativization themselves. He ventures that the contributors all hope that treating these terms in juxtaposition may allow for new configurations of inquiry. (shrink)

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

Abstract:Facial transplantation is emerging as a therapeutic option for self-inflicted gunshot wounds. The self-inflicted nature of this injury raises questions about the appropriate role of self-harm in determining patient eligibility. Potential candidates for facial transplantation undergo extensive psychosocial screening. The presence of a self-inflicted gunshot wound warrants special attention to ensure that a patient is prepared to undergo a demanding procedure that poses significant risk, as well as stringent lifelong management. Herein, we explore the ethics of considering mechanism of injury (...) in the patient selection process, referring to the precedent set forth in solid organ transplantation. We also consider the available evidence regarding outcomes of individuals transplanted for self-inflicted mechanisms of injury in both solid organ and facial transplantation. We conclude that while the presence of a self-inflicted gunshot wound is significant in the overall evaluation of the candidate, it does not on its own warrant exclusion from consideration for a facial transplantation.

Dual-Process Theories (D-PTs) claim there are two qualitatively different types of processes in the human brain-mind. Despite forming the basis for several areas of cognitive science, they are still shrouded in ambiguity: critics erroneously attack D-PTs as a whole (e.g., Evans and Stanovich Perspectives on Psychological Science, 8(3), 2013), the qualitative/quantitative distinction is not clear enough (De Neys Perspectives on Psychological Science 16 (6): 1412–1427, 2021; Dewey 2022) and, given this criterion, deciding between qualitative or quantitative differences may even be (...) scientifically irrelevant (De Neys 2021). As a way of disambiguating the discussion and clarifying what exactly means to claim the existence of a second type of process, I define two possible categories of D-PT: The substantial and the instrumental. In the substantial case, Type 2 processes are subpersonal level ones. In the instrumental case, Type 2 processing is a personal level phenomenon that does not necessarily imply subpersonal level Type 2 processes. Discussing the different implications of each of the categories, I use as a main example to illustrate the ambiguity – and the exercise of disambiguation – the model proposed by Evans and Stanovich (2013), making clear its substantial character, and contrast it with Frankish’ (2009) – a clear case of instrumental D-PT. Finally, I discuss the contributions this distinction can make. By making the discussion clearer, it can provide a relatively unanimous framework for dual- and single-process theorists (the instrumental version) and clearer desiderata for those wishing to defend the substantive one.

El objetivo de este trabajo es proponer una nueva versión del internismo relativo al estatuto de nuestras razones para actuar. El argumento tiene tres pasos: la ampliación de la psicología moral ortodoxa mediante el reconocimiento de la autoridad del amor en la agencia humana, la afi rmación de las relaciones interpersonales amorosas como analogado principal del amor y, por último, la consideración de una concepción no reductiva del amor y de la existencia de la real jerarquía de amores de los (...) agentes humanos.

In “A new proof of the completeness of the Lukasiewicz axioms” Chang proved that any totally ordered MV-algebra A was isomorphic to the segment \}\) of a totally ordered l-group with strong unit A *. This was done by the simple intuitive idea of putting denumerable copies of A on top of each other. Moreover, he also show that any such group G can be recovered from its segment since \^*}\), establishing an equivalence of categories. In “Interpretation of AF C (...) *-algebras in Lukasiewicz sentential calculus” Mundici extended this result to arbitrary MV-algebras and l-groups with strong unit. He takes the representation of A as a sub-direct product of chains A i, and observes that \ where \. Then he let A * be the l-subgroup generated by A inside \. He proves that this idea works, and establish an equivalence of categories in a rather elaborate way by means of his concept of good sequences and its complicated arithmetics. In this note, essentially self-contained except for Chang’s result, we give a simple proof of this equivalence taking advantage directly of the arithmetics of the the product l-group \, avoiding entirely the notion of good sequence.

Logic has been a—disputed—ingredient in the emergence and development of the now very large field known as knowledge representation and reasoning. In this book (in progress), I select some central topics in this highly fruitful, albeit controversial, association (e.g., non-monotonic reasoning, implicit belief, logical omniscience, closed world assumption), identifying their sources and analyzing/explaining their elaboration in highly influential published work.

El presente proyecto de investigación se ubica en el marco del equipo Innova de la Universidad de Deusto. “El equipo Innova es un equipo de investigación interfacultaticio que tiene como propósito el desarrollo de la innovación desde una perspectiva multifocal, ya que trata aspectos tan diversos como: organizativos, formativos y estructurales.” En este contexto se espera que la presente investigación pueda realizar una aportación sustancial en lo relativo al papel que desempañan las Competencias Genéricas en los procesos de educación superior. (...) Se estima que los resultados por alcanzar en este trabajo habrán de responder a demandas que se presentan en el contexto educativo actual, en el marco de una sociedad caracterizada por la complejidad. Uno de los aspectos innovadores que define a esta indagación es, en el concierto de la interdisciplinariedad mencionada líneas arriba, el abordar cuestiones centrales del saber pedagógico bajo la perspectiva de la Hermenéutica filosófica. Puntualmente se toman aquí dos temas que son muy caros para la Pedagogía, el primero de ellos es ‘el problema de la comprensión’ y el otro lo concerniente a la ‘significatividad’. En la literatura preponderante en el ámbito pedagógico el abordaje de estas dos categorías se realiza recurriendo a los aportes de la psicología cognitiva. En el presente trabajo se asume este dato, pero se aborda sistemáticamente desde otro campo disciplinar como es la Hermenéutica filosófica. Las disciplinas filosóficas en general y en este caso particular la Hermenéutica, entran en diálogo con diversos campos científicos, como aquí lo hacen con la Pedagogía, bajo una perspectiva crítica y, a la vez, totalizante. Es decir, procuran reunir los aportes de los diversos campos científicos al tiempo de atender las articulaciones y las tensiones que entre ellos puedan surgir, al abordar el problema desde un horizonte más amplio que el que cae bajo el específico objeto de estudio de cada disciplina. Se busca, de este modo, una adecuada articulación entre los aportes específicos de cada campo científico bajo una lectura integradora que es propia de la Filosofía. Este posicionamiento es fundamental y, en este sentido innovador, al procurar enriquecer el campo de las Competencias Genéricas mediante las ‘Competencias Semánticas’, que se mueven en el ámbito de la significatividad y el sentido, requisitos imprescindibles para que un sujeto pueda posicionarse personal y comunitariamente en una sociedad compleja. Para lograr este cometido se ha recurrido a una metodología de investigación cualitativa de análisis de contenido, que se ha aplicado a una selección de obras que refieren a la hermenéutica de H-G. Gadamer y P. Ricoeur. (shrink)

De acordo com as interpretações mais conhecidas (por exemplo, Hofmann, Strauss, Löwith ou Kuhn), o pensamento jurídico e político de Carl Schmitt mantém distância de Aristóteles. Este artigo tem a intenção de mostrar que a concepção de direito de Schmitt, apesar de ser desenvolvida em um contexto diferente, contém semelhanças significativas com o entendimento de direito em Aristóteles. Para mostrar essa proximidade, considera-se especialmente a noção de totalidade presente no conceito aristotélico de polis, que implica que a unidade política é (...) o principal modo de se realizar o direito. According to mostly known interpretations (e.g.: Hofman, Strauss, Löwith or Kuhn), the legal and political thought of Carl Schmitt keeps distance from Aristotle's. This article intends to show that Schmitt's concept of law, despite developed in a different context, holds significant likelihood with Aristotle's comprehension of law. With the Purpose of building this proximity, the notion of entirety present in the Aristotelic concept of polis implies that political unit is the main way to accomplish law. (shrink)

A diferencia de la filosofía ambiental colombiana, que alcanza un cierto grado de unidad debido a la influencia de la obra de Augusto Ángel-Maya, la filosofía ambiental argentina es más diversa en su panorama de puntos de vista y enfoques. A pesar de que no podría afirmarse que constituyen una filosofía ambiental propiamente tal, los escritos de Rodolfo Kusch podrían hacer una contribución significativa a un pensamiento ambiental anclado en las peculiaridades de nuestra cultura. Alicia Irene Bugallo ha trabajado (...) en temas de ecofilosofía, y ha introducido estos temas a jóvenes, educadores y el público en general. Alcira Bonilla ha introducido un tipo de eco-humanismo ético, que se mueve lejos del antropocentrismo a la vez que evita un fisiocentrismo o sacralización de la naturaleza. A diferencia de Bugallo y Bonilla, cuyas posiciones se acercan a la ecología profunda, María Julia Bertomeu ha enfatizado la necesidad de una clarificación normativa de reglas generalizables orientadas hacia la protección medioambiental. La Escuela Marina Vilte de la Confederación deTrabajadores de la Educación de la República Argentina ha sido un auténtico catalizador formando una nueva generación de educadores con un enfoque en temas ambientales. Un grupo de colaboración de intelectuales que trabaja en pensamiento crítico, encabezado por su coordinador Guido Galafassi, ha creado la revista Theomai y elaborado una crítica de nuestra actual situación socio-ambiental. En cuanto a nuestros medios de comunicación de masas, durante varias décadas Miguel Grinberg y Antonio Brailovsky han sido figuras inspiradoras que han difundido los temas ambientales. (shrink)

This article presents a critical account of Agamben’s understanding of the logic of sovereignty and of the notion bare life, particularly Agamben’s approach to the paradox of sovereignty and its relation to Aristotle’s metaphysical category of potentiality. With regards to bare life, it brings together an analysis of the figure of the homo sacer with an account of Agamben’s use of paradigms as methodological tools. The first part of the paper argues that Agamben ontologises sovereignty by dramatising the paradox of (...) its structure as im-potentiality. The second part claims that even though an account of Agamben’s methodology serves to respond to the different critiques that his notion of bare life has raised, Agamben’s notions of sovereignty and of bare life ultimately rely on Schmitt’s decisionism. El artículo hace un recuento crítico de la forma en que Agamben entiende la lógica de la soberanía y la noción de nuda vida, particularmente su abordaje de la paradoja de la soberanía y su relación con la categoría metafísica aristotélica de la potencialidad. Con respecto a la nuda vida, combina el análisis de la figura del homo sacer con un recuento del uso que hace Agamben de los paradigmas como herramientas metodológicas. En la primera parte del ensayo, se argumenta que Agamben ontologiza la soberanía al dramatizar la paradoja de su estructura como im-potencialidad. En la segunda, se afirma que aunque la descripción de la metodología de Agamben sirve para responder a las diferentes críticas suscitadas por su noción de nuda vida, sus nociones de soberanía y de nuda vida dependen, en última instancia, del decisionismo de Schmitt. Este artigo apresenta a versão crítica do entendimento de Agamben sobre a lógica da soberania e da noção de vida nua. Em particular, a aproximação de Agamben para o paradoxo da soberania e da sua relação com a categoria metafísica da potencialidade de Aristóteles. No que diz respeito à vida nua, reúne uma análise da figura do homo sacer com uma explicação do uso de Agamben de paradigmas como ferramentas metodológicas. Na primeira parte deste artigo, argumenta-se que Agamben ontologiza a soberaniadramatizando o paradoxo de sua estrutura como im-potencialidade. Na segunda parte, será alegado que, apesar de uma explicação da metodologia de Agamben ter servido para responder às diferentes críticas que sua noção de vida nua tenha levantado, em última análise, duas noções da soberania e vida nua de Agamben dependem do "decisionismo schmittiano".

The following article presents a reconstruction of "weak thought" against the background of Italian philosophy after the Second World War and specifically in relation to the philosophical schools that were active and influential in Turin. At that time, Gianni Vattimo belonged to a tradition that was influenced by the religious consequences of existential philosophy (above all the thought of Luigi Pareyson): a tradition that links Vattimo with Martin Heidegger and Friedrich Nietzsche. All these elements - highly generic in character as (...) they often were - came together to produce the notion of "weak thought," which soon came to be seen as a response to the positivist and anti-religious philosophies of the period (e.g. the neo-Enlightenment movement that was represented by Nicola Abbagnano, Norberto Bobbio, Ludovico Geymonat). Vattimo challenged these traditions not through recourse to a set of theoretical principles, but through a different style of thinking altogether, and this is the true (and ambiguous) strength of weak thought.

Charles Peirce, Mikhail Bakhtin and Thomas Sebeok all develop original research itineraries around the sign and, despite terminological differences, canbe related with reference to the concept of dialogism and modelling. Jakob von Uexküll’s biosemiosic “functional cycle”, a model for semiosic processes, is alsoimplied in the relation between dialogue and communication.Biological models which describe communication as a self-referential, autopoietic and semiotically closed system (e.g., the models proposed by Maturana,Varela, and Thure von Uexküll) contrast with both the linear (Shannon and Weaver) and (...) the circular (Saussure) paradigms. The theory of autopoietic systems is only incompatible with dialogism if reference is to a linear causal model which describes communication as developing from source to destination, or to the conversation model governed by the turning around together rule. Dialogism understood in biosemiotic terms overlaps with the concepts of interconnectivity,interrelation, intercorporeity and presupposes the otherness relation.As Uexküll says, the relation with the umwelt in nonhuman living beings is stable and concerns the species; on the contrary, in human beings it is, changeableand concerns the single individual, which is at once an advantage and a disadvantage. Thanks to “syntactics”, human beings can construct, deconstruct and reconstruct an infinite number of worlds from a finite number of elements. This distinguishes human beings from other animals and determines their capacity for posing problems and asking questions. The human being not only produces his or her own world, but can also endanger it, and even destroy it to the point of causing the extinction of all other life forms on Earth. The unique capacity for reflection on signs makes human beings responsible for life across the planet, both human and nonhuman. Such reflections shift semiotic research in the direction of semioethics. (shrink)
