We consider a 2-valued non-deterministic connective \({\wedge \!\!\!\!\!\vee }\) defined by the table resulting from the entry-wise union of the tables of conjunction and disjunction. Being half conjunction and half disjunction we named it _platypus_. The value of \({\wedge \!\!\!\!\!\vee }\) is not completely determined by the input, contrasting with usual notion of Boolean connective. We call non-deterministic Boolean connective any connective based on multi-functions over the Boolean set. In this way, non-determinism allows for an extended notion of truth-functional connective. (...) Unexpectedly, this very simple connective and the logic it defines, illustrate various key advantages in working with generalized notions of semantics (by incorporating non-determinism), calculi (by allowing multiple-conclusion rules) and even of logic (moving from Tarskian to Scottian consequence relations). We show that the associated logic cannot be characterized by any finite set of finite matrices, whereas with non-determinism two values suffice. Furthermore, this logic is not finitely axiomatizable using single-conclusion rules, however we provide a very simple analytic multiple-conclusion axiomatization using only two rules. Finally, deciding the associated multiple-conclusion logic is \(\mathbf {coNP}\) -complete, but deciding its single-conclusion fragment is in \({\mathbf {P}}\). (shrink)

ABSTRACT In Planning, Time, and Self-Governanace, Bratman argues that the notion of self-governance plays an important role in grounding the rational principles such as means-ends coherence in the synchronic case, and principles of stability and coherence through time in the case of self-governance over time. In this paper, I grant Bratman’s claim for the synchronic case, however I argue that it is not clear that one can extend the reasoning to the diachronic case. More specifically, I raise a number of (...) doubts about whether any notion of diachronic self-governance can play the role in the theory of practical rationality that Bratman assigns to it.

En este trabajo busco aproximarme a una historia in-finita de la naturaleza en el pensamiento-en-imagen de Paul Klee a partir de una interpretación de los parágrafos 76 y 77 de la Crítica de la facultad de Juzgar de Kant. Para su lectura, propongo considerar como contrapunto uno de los principios del entendimiento puro que Kant considera en la Crítica de la razón pura, este es: el principio de las anticipaciones de la percepción. A saber, el principio que explica la condición (...) de toda sensación. Para preguntar por una historia in-finita de la naturaleza es fundamental atender a la diferencia implicada en la relación entre naturaleza y arte que advierte Klee. Dicha diferencia conlleva considerar el origen de esta historia como fractura por la atención puesta hacia lo que la diferencia, lo cual exige pensar en lo que denomino un cambiode percepción.

The COVID-19 pandemic produced immeasurable impacts on the economy, education, and socialization, besides the loss of millions of lives. Thus, there has been an accelerated development of an unprecedented number of COVID-19 vaccine candidates to control the pandemic. The World Health Organization’s emergency use authorization of COVID-19 vaccines still in clinical trial allowed immunizing the population. This paper presents a perspective of the bioethical precepts of autonomy, non-maleficence, beneficence, and justice in the emergency use of COVID-19 vaccines. Furthermore, it emphasizes (...) the importance of surveillance at all stages of vaccine development to detect adverse effects and ensure compliance with bioethical precepts. (shrink)

Sex has become to-day a sort of secular religion, i.e. a mass-belief in a new world entirely redeemed from its evils by revolution. Hope in revolution presupposes the ideas of man's original innocence and of society'sresponsibility for evil. As no political or economical revolution can entirely liberate man from his aggressiveness, the sexual revolution isproposed as the basic step towards the new world. But a totally free sexuality, breaking the dialectics between Eros and Thanatos, gives way to the deathinstinct and (...) therefore to a world of struggle for domination, not of liberty. (shrink)

No social life is possible without order. Order being the most constituent element of society, it is not surprising that so many theories have been developed to explain what social order is and how it is possible, as well as to explore the features that social order acquires in its different dimensions. The book leads these many theories of social order back to a few main matrices for the use of theoretical and practical reason, which are defined as 'paradigms of (...) order'. The plurality of conceptual constructs regarding social order is therefore reduced to a manageable number of theoretical patterns and an intellectual map is produced in which the most significant differences between paradigms are clearly outlined. Furthermore, the 'paradigmatic revolutions' are addressed that marked the most relevant turning points in the way in which a 'well-ordered society' should be understood. Against this background, the question is discussed on the theoretical and practical perspectives for a cosmopolitan society as the only suitable possibility to meet the global challenges with which we are all presently confronted.

Qual o sentido da vida? Por que aqui estamos? Será destino? Será escolha? Neste livro, Mario Sergio Cortella e Leandro Karnal, dois dos maiores pensadores contemporâneos no Brasil, se encontram para refletir sobre essas questões que há séculos fascinam e intrigam a humanidade. A ciência, a filosofia, a religião e a arte têm oferecido algumas possibilidades de resposta que os autores discutem aqui. Afinal, pode ser aterrador imaginar que não há um destino, algo que explique a nossa existência. Por (...) outro lado, a ausência de sentido nos deixa livres para ser e viver conforme desejarmos - embora isso implique também responsabilidade. Mas somos mesmo livres? Seja escolha ou destino, seja a vida um drama que vamos tecendo ou uma tragédia anunciada, fato é que estamos sempre a procurar algum propósito que torne a existência mais significativa. Mas o que explica que algumas pessoas tenham mais sucesso do que outras no que fazem? Seria dom, vocação ou resultado de um esforço? Como os autores apontam, talvez a vida seja menos inspiração e mais transpiração. (shrink)

This paper adopts a symmetrical approach tocontroversies over R.H. MacArthur and E.O. Wilson'sequilibrium model of island biogeography, in order toshow how different interpretations of the model dependupon different philosophical understandings of theapplication of models and theories. In particular,there are quite distinct domains to which the modelcould apply; in addition, some equivocation amongthese domains is important to the model's success.Therefore, apparently inconsistent interpretations,interpretations that fit into roughly instrumentalist,realist and rationalist conceptions of science, may bemutually supporting in practice. Descriptions ofscientific practice, then, (...) should not adjudicate amongthese interpretations, but should instead recognizeways in which successful models translate amongdomains, and in so doing can become realistic,instrumentally successful, or rationally established.As complex social objects, models can afford complexrepresentational relations.

Este artículo analiza los aspectos metodológicos principales del proyecto heideggeriano de una ontología fundamental. Heidegger considera que no hay un punto de partida privilegiado, porque todos estamos hermenéuticamente situados. Por ello propone que la investigación filosófica comience justo donde ya nos encontramos. Esto significa que debemos apropiarnos de nuestra situación hermenéutica. La explicación de esta idea mostrará la clave metodológica de la ontología heideggeriana: la indicación formal. Ella habilita un acceso al fenómeno sin abandonar el marco de la facticidad.

En su ensayo Para una crítica de la violencia, Walter Benjamin reivindica el fenómeno social de la huelga general revolucionaria teorizada por Georges Sorel en su obra Reflexiones sobre la violencia, como una figura ejemplar de lo que sería un “medio puro de la política”, al margen de cualquier forma legitimada de poder. En este marco, pocos comentadores contemporáneos advierten una discordancia conceptual entre ambos filósofos: para Sorel, la huelga revolucionaria es un mito social, mientras que el mito, categoría esencialmente (...) negativa en Benjamin, describe la violencia que aprisiona la vida y que se traduce en una forma de poder político superior. En este artículo quisiéramos demostrar esta discordancia conceptual para examinar en seguida cómo ha sido comentada por otros pensadores contemporáneos. La filosofía de la historia, la posibilidad de una acción política ética y la temporalidad mesiánica aparecen en el horizonte teórico que emparenta a estos filósofos y por el cual podría descifrarse su impasse conceptual. Esto se confirma si se despliega la idea de un “medio puro de la política”, pista que Benjamin ofrece sin profundizar y sobre la cual reenvía al pensamiento de un filósofo poco explorado, Erich Unger. En la última parte de este artículo desarrollaremos las claves dadas por Unger, que entran justamente en sintonía con la mención de la huelga general como medio puro de la política. In his Critique of violence, Walter Benjamin claimed that the social phenomenon of the revolutionary general strike was an example of what would be a “pure political mean”. In this context, not many contemporary commentators note an important conceptual incoherence between those two philosophers: for Sorel the revolutionary general strike is a social myth, while in Benjamin the category of myth, essentially negative, describes the violence that imprisons life and crystallizes it in a higher form of political power. In this article, we demonstrate this conceptual discrepancy in order to examine the way it has been approached by other philosophers. The philosophy of history, the possibility of an ethical political action, and messianic temporality, all appear on the theoretical horizon linking these philosophers, and through these ideas a conceptual impasse can be decoded. Moreover, this horizon can be confirmed if we follow the idea of a “pure political means” that Benjamin proposes and which moves forward to the thought of an unexplored philosopher mentioned by him: Erich Unger. In the last part of this article we will develop the keys given by Unger, which fall right in line with the notion of the general strike as a pure political mean. (shrink)

A Hilbert algebra with supremum is a Hilbert algebra where the associated order is a join-semilattice. This class of algebras is a variety and was studied in Celani and Montangie . In this paper we shall introduce and study the variety of $${H_{\Diamond}^{\vee}}$$ H ◊ ∨ -algebras, which are Hilbert algebras with supremum endowed with a modal operator $${\Diamond}$$ ◊ . We give a topological representation for these algebras using the topological spectral-like representation for Hilbert algebras with supremum given in (...) Celani and Montangie . We will consider some particular varieties of $${H_{\Diamond}^{\vee}}$$ H ◊ ∨ -algebras. These varieties are the algebraic counterpart of extensions of the implicative fragment of the intuitionistic modal logic $${\mathbf{IntK}_{\Diamond}}$$ IntK ◊ . We also determine the congruences of $${H_{\Diamond}^{\vee}}$$ H ◊ ∨ -algebras in terms of certain closed subsets of the associated space, and in terms of a particular class of deductive systems. These results enable us to characterize the simple and subdirectly irreducible $${H_{\Diamond}^{\vee }}$$ H ◊ ∨ -algebras. (shrink)

This is a book review of "The Metaphysics of Sensory Experiencie" by David Papineau.

Designers’ intentions are important for determining an artifact’s proper function (i.e., its perceived real function). However, there are disagreements regarding why. In one view, people reason causally about artifacts’ functional outcomes, and designers’ intended functions become important to the extent that they allow inferring outcomes. In another view, people use knowledge of designers’ intentions to determine proper functions, but this is unrelated to causal reasoning, having perhaps to do with intentional or social forms of reasoning (e.g., authority). Regarding these latter (...) social factors, researchers have proposed that designers’ intentions operate through a mechanism akin to social conventions, and that therefore both are determinants of proper function. In the current work, participants learned about an object’s creation, about social conventions for its use and about a specific episode where the artifact was used. The function implemented by the user could be aligned with the designer’s intended function, the social convention, both, or neither (i.e., an opportunistic use). Importantly, the use episode always resulted in an accident. Data show that the accident negatively affected proper function judgments and perceived efficiency for conventional and opportunistic functions, but not for designers’ intended functions. This is inconsistent with the view that designers’ intentions are conceptualized as causes of functional outcomes and with the idea that designers’ intentions and social conventions operate through a common mechanism.

Standpoint theory makes the claim that there are social positions from which privileged perspectives on knowledge can be obtained. This article describes some arguments that stake out relatively narrow grounds for the relevance of standpoint theory to science and technology: namely, the oppressed are in a potentially good position to understand social relations. Although these grounds seem narrow and apparently irrelevant to the bulk of the activity of the sciences, recent work in science and technology studies indicates that social relations (...) are topics and resources as much in physics and mathematics as in primatology and psychology. So, if we accept the arguments for standpoint theory, the social picture of science should lead us to recognize the wide-ranging applicability of standpoint theory to science. (shrink)

These two volumes consist of a critical edition and English translation of the two earliest known Armenian sets of scholia on the Heavenly Hierarchy of Dionysius the Areopagite. Composed in the monastic schools of Erznka in the late thirteenth century, these scholia provide significant insight into how the Heavenly Hierarchy in particular, and Armenian translations of Greek texts in general, were understood by Armenian scholars in the Middle Ages. This editio princeps of the scholia represents a rare critical edition of (...) a native Armenian composition from the medieval period. In addition to the text and translation, these volumes include a textual commentary as well as a critical collation and English translation of a number of scholia from the Armenian version of the Greek scholia on the Heavenly Hierarchy.

Existen conceptos o concepciones sobre la realidad que permean asiduamente el despliegue del pensamiento y la vida en sus devenires cotidianos o fácticos. En este sentido, quien comienza a formarse en los quehaceres de la investigación filosófica, encara con alguna frecuencia la responsabilidad de confrontar aquellas nociones que, bajo la forma de precomprensiones, obstruyen las transiciones comprensivas e interpretativas propias de toda tarea investigativa. En este caso, la posibilidad de distinguir el contenido característico de las ideologías naturalistas, de aquellas otras (...) que le son propias a las filosofías trágicas o inmanentistas, quizá pueda incidir argumentalmente en las tensiones dialógicas que hoy atraviesan a las culturas cuando se pone de manifiesto el deseo de reivindicar posiciones totalitarias o relativistas en relación con esferas de la vida y del pensamiento humanos tan diversas como la política, la religión, el género, la sexualidad, la etnia, la raza, entre otras. La tarea de quien se forma en investigación filosófica consiste, en buena medida, en advertir que los conceptos filosóficos logran vivificarse cuando ceden a la interlocución vital que les proponen constantemente las contingencias propias de todo lapso histórico. En efecto, algunos asuntos se palpan en la atmósfera de un tiempo determinado; también se encuentran en las tramas tangibles de las existencias humanas. (shrink)

The discovery of the role of models in science by Granger parallels the analogous discovery made by Mary Hesse and Marx Wartofsky. The role models are granted highlights the linguistic dimension of science, resulting in a 'softening' of Bachelard's rationalistic epistemology without lapsing into relativism. A 'linguistic' theory of metaphor, as contrasted with Bachelard's 'psychological' theory, is basic to Granger's account of models. A final paragraph discusses to what extent Granger's 'mature' theory of models would imply a revision of his (...) early economic methodology. (shrink)

This paper argues that the idea of “self-recognition” is fruitful for a critical theory of recognition like the one found in Axel Honneth’s work. Yet, it has repeatedly been ignored both by Honneth himself and by the secondary literature. By contrast, I submit that it can productively contribute to a better approach to some of the problems and paradoxes present in this author’s model, particularly those derived from an excessively intersubjective, psychologistic perspective. There are several phenomena that, to my mind, (...) could be better explained by means of the idea of “self-recognition”, among them, the origin of recognition struggles, the distinction between justified and unjustified demands for recognition, and the normativity of our practical self-relation. Although I do not intend to develop a complete taxonomy, I propose that “self-recognition” is relevant for a critical theory of recognition (and for social theory in general) in at least two senses: as “normative self-understanding” of the subject and as “knowing oneself in the other”, where the “other” is either a material object, person or social institution.

La pandemia del SARS-CoV-2 ha creado un desafío sin precedentes para la educación. En 2020, como resultado de las medidas para reducir la propagación del SARS-CoV-2, muchas instituciones educativas pasaron del aprendizaje presencial al aprendizaje remoto. Sin embargo, este modelo educativo puede generar estrés y ansiedad adicionales a la ansiedad provocada por la pandemia. Los objetivos del presente estudio fueron: 1) comparar las perspectivas de estudiantes y docentes sobre el número de horas dedicadas a las clases, y 2) determinar las (...) principales dificultades que enfrentan docentes y estudiantes, respectivamente, al pasar al sistema de educación en línea. Para realizar esta investigación se realizó una encuesta online en países de habla hispana, utilizando una muestra de 1.048 participantes anónimos. A través de los datos recopilados. Se analizaron el uso de plataformas, los tipos de equipos, los niveles de angustia y las posibles razones de esta angustia. Esta pandemia es una de las amenazas de salud pública más importantes de la historia reciente y ha afectado nuestras vidas de manera significativa, siendo una de las más importantes la futura adaptación de escuelas, estudiantes y docentes a una nueva forma de aprender.

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.

Este artículo propone una interpretación estética de la relación entre los sistemas filosóficos de Spinoza y Nietzsche a partir una base ontológica común. Aunque sea difícil defender una lectura de Spinoza por parte de Nietzsche, si nos dirigimos a la mediación desde el pensamiento indio entre los pilares de sus respectivos sistemas, podremos fundar una relación entre la voluntad de poder y el _conatus _spinozista. El propósito de esta investigación es doble: por un lado, proponer una interpretación estética de la (...) filosofía de Spinoza desde su sistema de los afectos; y, a partir de ahí, apuntar al fundamento afectivo de esta estética desde la voluntad de poder nietzscheana.

Democracy and education crisis in Brazil: a contribution of freirean thought to the debate Abstract: This article is the result of a research project, which seeks to establish a South-South dialogue between the thought of educator Paulo Freire and sociologist Boaventura Santos, focusing on the themes of democracy and public education in the current situation of Brazilian society (2014-2020). This research was based on a qualitative approach, prioritizing bibliographic and documentary research. However, for the purpose of delimiting this article and sharing some results, I focus the analysis on the contribution of Paulo Freire's thought from the Southern margins, based on his concept of “being more”, to debate this crisis of democracy and public education in the country's current situation. Based on this concept of “being more”, it was possible to identify both the structuring limits of liberal democracy in society, in particular in education, and the need to bring out other non-Eurocentric interpretations of these themes, as well as showing a scenario of acute democratic setback, which demonstrates advancing in the condition of “being less” and, therefore, profoundly distorting the ontological vocation of being more.

Este texto plantea una lectura de la propuesta estética del joven Nietzsche desde una óptica de la estética de las pasiones en su teoría de la voluntad de poder. Se analiza el desarrollo intelectual desde El nacimiento de la tragedia hasta su conversión psicofisiológica del arte en la etapa de madurez, a la vez que se estudia la repercusión de esta evolución en su planteamiento desde la psicología de los afectos. De esta forma, aunque es cierto que el transcurso intelectual (...) de Nietzsche cambia en el momento que abandona la metafísica del artista, continúa ahondando en una propuesta estética desde las tendencias afectivas de la psicología y el cuerpo.
