Definiciones de epistemología hay muchas, al igual que clases y estilos. Sin embargo, más allá de esta diversidad, es necesario contar con una definición básica que guíe nuestra comprensión del tema. Dos serán las preguntas que nos ayuden a ello en este artículo: a) ¿qué es la epistemología? y b) ¿para qué le sirve al científico?

We obtain, for the first time, a modular many-valued semantics for combined logics, which is built directly from many-valued semantics for the logics being combined, by means of suitable universal operations over partial non-deterministic logical matrices. Our constructions preserve finite-valuedness in the context of multiple-conclusion logics, whereas, unsurprisingly, it may be lost in the context of single-conclusion logics. Besides illustrating our constructions over a wide range of examples, we also develop concrete applications of our semantic characterizations, namely regarding the semantics (...) of strengthening a given many-valued logic with additional axioms, the study of conditions under which a given logic may be seen as a combination of simpler syntactically defined fragments whose calculi can be obtained independently and put together to form a calculus for the whole logic, and also general conditions for decidability to be preserved by the combination mechanism.

El materialismo salvaje desarrollado por Jacques Lezra no solo se opone a las cosmologías y ontologías modernas, articuladas en torno a un principio de organización de lo que hay, sino que también se expresa políticamente bajo la forma de un republicanismo salvaje que difiere no solo del republicanismo liberal sino también del llamado republicanismo normativo ilustrado. ¿De qué trata este republicanismo salvaje, abierto a la diferencia entre terror y terrorismo?, ¿qué consecuencias tiene su desmontaje de los presupuestos normativos y soberanos (...) del pensamiento onto-político occidental? Y, finalmente, ¿qué función/posición cumple/ocupa el poema, no solo el poema lucreciano, sino el poema en general (si hay tal cosa), para esta imaginación política aleatoria, defectiva y salvaje? Con estas preguntas procedemos a interrogar una de las múltiples aristas de un pensamiento concernido con la mundanidad del pensar, cuya relevancia parece ser evidente. Al final, incorporaremos algunas reflexiones sobre el poema de Néstor Perlongher, “Cadáveres” (1987), como caso de la proliferación lucreciana de lo que hay. (shrink)

The word “legitimacy” and its derivations (legitimate, legitimation, etc.) are widely employed in scientific language as they also are in current usage. In fact, we find them in several areas, from that of reasoning (“this conclusion is legitimate”) to that of law (“judgment of legitimacy”, “legitimate family”) and politics (“legitimate sovereign”). It is particularly in this latter domain, however, that they have their normal use as qualifications for power, and it is this particular aspect that I shall consider in this (...) paper. In accredited political language “legitimacy” designates a principle, or criterion, of justification for power (acting and commanding) and, correlatively, of the obedience that is its due. (shrink)

In the philosophy of science, abstraction has usually been analyzed in terms of the interface between our experience and the design of our concepts. The often implicit assumption here is that such interface has a definite identifiable and universalizable structure, determining the epistemic correctness of any abstraction. Our claim is that, on the contrary, the epistemic grounding of abstraction should not be reduced to the structural norms of such interface but is also related to the constraints on the cognitive processes (...) of specific abstractions. This suggests that we should understand abstraction as embodied in different kinds of abstraction practices. (shrink)

La filosofía de la ciencia se desarrolló durante la primera mitad del siglo xx bajo el supuesto de que la ciencia podía caracterizarse por la estructura lógica tanto del conocimiento articulado en las teorías más exitosas como de sus explicaciones. En la segunda mitad del siglo xx se cuestiona fuertemente esa idea, pero se sigue asumiendo que la filosofía de la ciencia debe hacerse siguiendo los cánones de una epistemología fundamentalista que considera que el avance de la ciencia pasa por (...) una ontología cada vez mas austera guiada por la idea de "mientras menos mejor". Desde esta perspectiva fundamentalista, el que las diferentes ciencias hablen de diferentes tipos de cosas es un obstáculo al entendimiento, producto de la imperfección del conocimiento actual. Este ideal nos invita a pensar que la epistemología debe hacerse reflexionando sobre el conocimiento articulado en nuestras teorías más austeras y nos compromete con propuestas reduccionistas problemáticas que no permiten explicar la diversidad de recursos epistémicos que de hecho utilizan los científicos. En este libro promovemos una epistemología que no sigue el lema de "mientras menos mejor", sino el de "organizar nuestros recursos epistémicos de manera que se genere entendimiento". Así, la misma estructura de las explicaciones y las prácticas (que incluye métodos y normas respecto de lo que se considera plausible y valioso) es lo que nos da la pauta para responder a la pregunta de qué es lo que hay. Esta estrategia epistémica nos obliga a hacer una filosofía de la ciencia muy cercana a la ciencia, reconociendo la pluralidad de sus métodos, objetivos y prácticas, sin reducir la filosofía de la ciencia a la sociología o a cualquier otra ciencia en particular.

During the 19th century, evolutionary models of innovation followed a famous thesis of continuity, according to which methods and explanatory patterns of biology should have an important say in the social sciences. In the 20th century, this thesis was considered unacceptable as part of the sharp separation of biology from the social sciences. Recent advances in the biological sciences suggest a way in which a version of the thesis of continuity can be reinstated, to suggest new ways of explaining innovation (...) in the social sciences. Key kinds of innovation can be explained in terms of the evolution of robust complex systems, interpreted as processes of path creation. (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.

In recent decades, memory studies in Colombia in relation to the internal armed conflict have become a point of reference for multidisciplinary work with collectives and communities, and are also an important topic on the state agenda. This article explores the remembering subjectivities, narrative marks and cultural trauma that emerge from the experiences and perspectives in a memory work Antiguo Espacio Territorial de Capacitación y Reincorporación (AETCR) de Pondores. In addition, the tensions involved in thinking about cultural trauma from subjects (...) marked by the exercise of armed violence are analyzed. For this purpose, a narrative analysis is developed that integrates thematic recurrences, expression of the experience, features of orality and structure of the story. The methods used to carry out this study include a participatory approach and life stories of reincorporated persons and the surrounding community in the context of the AETCR. The study focuses on the ways in which memory expressed narratively conceives practices such as forgiveness and coexistence as possible experiences, through the experiences and thoughts of the AECTR community.

This paper focuses on order-preserving logics defined from varieties of distributive lattices with negation, and in particular on the problem of whether these can be axiomatized by means Hilbert-style calculi that are finite. On the negative side, we provide a syntactic condition on the equational presentation of a variety that entails failure of finite axiomatizability for the corresponding logic. An application of this result is that the logic of all distributive lattices with negation is not finitely axiomatizable; we likewise establish (...) that the order-preserving logic of the variety of all Ockham algebras is also not finitely axiomatizable. On the positive side, we show that an arbitrary subvariety of semi-De Morgan algebras is axiomatized by a finite number of equations if and only if the corresponding order-preserving logic is axiomatized by a finite Hilbert-style calculus. This equivalence also holds for every subvariety of a Berman variety of Ockham algebras. We obtain, as a corollary, a new proof that the implication-free fragment of intuitionistic logic is finitely axiomatizable, as well as a new corresponding Hilbert-style calculus. Our proofs are constructive in that they allow us to effectively convert an equational presentation of a variety of algebras into a Hilbert-style calculus for the corresponding order-preserving logic, and vice versa. We also consider the assertional logics associated to the above-mentioned varieties, showing in particular that the assertional logics of finitely axiomatizable subvarieties of semi-De Morgan algebras are finitely axiomatizable as well.

Morality has traditionally been described in terms of an impartial and objective “moral law”, and moral psychological research has largely followed in this vein, focusing on abstract moral judgments. But might our moral judgments be shaped not just by what the action is, but who is doing it? We looked at ratings of moral wrongness, manipulating whether the person doing the action was a friend, a refugee, or a stranger. We looked at these ratings across various moral foundations, and conducted (...) the study in Brazil, US, and UK samples. Our most robust and consistent findings are that purity violations were judged more harshly when committed by ingroup members and less harshly when committed by the refugees in comparison to the unspecified agents, the difference between refugee and unspecified agents decays from liberals to conservatives, i.e., conservatives judge them more harshly than liberals do, and Brazilians participants are harsher than the US and UK participants. Our results suggest that purity violations are judged differently according to who committed them and according to the political ideology of the judges. We discuss the findings in light of various theories of groups dynamics, such as moral hypocrisy, moral disengagement, and the black sheep effect. (shrink)

We show that for an arbitrary logic being locally tabular is a strictly weaker property than being locally finite. We describe our hunt for a logic that allows us to separate the two properties, revealing weaker and weaker conditions under which they must coincide, and showing how they are intertwined. We single out several classes of logics where the two notions coincide, including logics that are determined by a finite set of finite matrices, selfextensional logics, algebraizable and equivalential logics. Furthermore, (...) we identify a closure property on models of a logic that, in the presence of local tabularity, is equivalent to local finiteness. (shrink)

This paper reviews the main pricing policies in Latin American countries, discussing their shortcomings. It also gives an overview of the most common pricing and reimbursement policies in Europe and describes in detail three well-established approaches — international price referencing, value-based pricing, including setting up of health technology assessment, and generic and biosimilar policies — building on country examples.

María Egües (1917-2008) fue una investigadora y tecnóloga en el ámbito de los instrumentos ópticos; figura esencial para entender el desarrollo de la ingeniería óptica en las primeras décadas del franquismo. Partiendo de dos fotografías, hasta hace poco inéditas, que reflejan dos momentos cruciales de su vida profesional, este ensayo ofrece una reflexión sobre como una mujer como Egües se vio a sí misma en un tiempo en el que la mera presencia de una mujer en el sistema tecno-científico era, (...) en no pocas ocasiones, rechazada o ignorada. A partir del recurso metafórico de los periscopios submarinos, los cuales permiten ver sin ser vistos, aquella tecnóloga, cual submarino, pudo progresar en unas instituciones, el CSIC, la Universidad y el Ejército, auténticos resortes tecnológicos del Estado franquista, ante miradas hostiles o recelosas. Con todo, aquel régimen, que, parafraseando a Pedro Laín, con su «atroz desmoche», tanto había cercenado al árbol de la ciencia española, no podía permitirse despreciar la participación de algunas mujeres como Egües, imprescindibles en la reconstrucción de un sistema tecno-científico, tan necesario para la supervivencia del propio sistema, a pesar de ciertas retóricas atávicas. Así ocurrió con el desarrollo de una nada desdeñable industria de instrumentos ópticos, en especial, cómo no, aquellos de uso militar. Ámbito en el que María Egües, con forzada discreción y perseverante esfuerzo, alcanzaría uno de los más notables hitos: el diseño y fabricación de los primeros periscópios netamente españoles del siglo XX.

We offer a new and robust model of the emergence and persistence of cooperation when interactions are anonymous, the population is well mixed, and evolution selects strategies according to material payoffs. The model has a Prisoner’s Dilemma structure, but with an outside option of non-participation. The payoff to mutual cooperation is stochastic; with positive probability, it exceeds that from cheating against a cooperator. Under mild conditions, mutually beneficial cooperation occurs in equilibrium. This is possible because the non-participation option holds down (...) the equilibrium frequency of cheating. Dynamic properties of the model are investigated theoretically and through simulations based on replicator dynamics. (shrink)

The aim of this paper is to analyze a fragment by Porphyry concerning Seleucid history and transmitted by Eusebius of Caesarea's Chronicon. A short introduction on this work will be followed by a defense of the authorship of the fragment as Porphyrian, and by a cautious suggestion to assign it to the Contra Christianos. In the last section, the fragment will be examined at length and its ideological background will be highlighted. In particular, the account of Seleucid kings' deaths shows (...) that Porphyry turned to sources favorable to that dynasty. A critical voice seems to raise only when the author recounts of Demetrius I and of his descendants. (shrink)

I construct a quantum-logical model of the type of situation that seems to be at the root of the problem of interpreting the projection postulate (Luders' rule) as a criterion of minimal disturbance. It is shown that the most natural way of characterizing minimal disturbance leads to contradictory conclusions concerning the final state.

O presente artigo visa estabelecer relações entre a teoria do Neodocumentalismo da Ciência da Informação e alguns aspectos expostos nos sistemas filosóficos da Filosofia de Ludwig Wittgenstein, sobretudo da sua segunda fase, tal como exposto em sua obra Investigações Filosóficas. Neste sentido, pretende-se estabelecer relações convergentes entre o conceito de jogos de linguagem e os aspectos relativos ao documento como instrumento de veiculação de informação, ordenação e prática social. Após uma introdução do tema, serão apresentados os conceitos e configurações do (...) Neodocumentalismo no âmbito da Ciência da Informação. Em seguida, será feita uma apresentação do sistema de Wittgenstein, sobretudo o sistema de sua segunda fase e, logo após, serão abordados aspectos convergentes e considerações entre Neodocumentalismo e jogos de linguagem.

Neste trabalho analiso os principais modelos meta-teóricos sobre a relação teoria/ experiência. Com esse objetivo, destaco as diversas relações inferenciais existentes entre as teorias e a experiência nos processos de descoberta e nos processos de justificação, tendo como marco de análise a distinção entre teorias fenomenológicas e teorias explicativas.

Consideramos no artigo a afirmação cética de que devemos suspender o juízo nos casos de desacordo. Discutimos brevemente o argumento para a suspensão de juízo nos casos de desacordo apresentados por Sexto Empírico e propomos um argumento com base nas considerações de Feldman sobre o desacordo entre pares epistêmicos. Desenvolvemos então três objeções a esse argumento.

I compare the concepts of “activation” and “storage” as foundations of short-term memory, and suggest that an attention-based view of STM does not need to posit specialized short-term stores. In particular, no compelling evidence supports the hypothesis of time-limited stores. Identifying sources of activation, examining the role of activated procedural knowledge, and studying working memory development are central issues in modelling capacity-limited focal attention.

This article describes a study on capacity limitations that affect the construction of spatial mental models. A process model is presented, according to which the construction of a mental model in Ehrlich and Johnson-Laird's (1982) spatial descriptions task places a workload of six information chunks for continuous and semi-continuous descriptions, and seven chunks for discontinuous descriptions. Participants (48 undergraduate students) performed the spatial descriptions task and the figural intersections test (FIT), which yields a capacity score. The pattern of errors and (...) sentence reading times in the spatial descriptions task confirmed that participants were using mental models. The FIT score was positively correlated with accuracy in the spatial descriptions task. Prediction analysis of cross-classification tables showed that, for successful performance in continuous and semi-continuous descriptions, a FIT score of 6 was necessary, and a score of 7 in discontinuous descriptions. These results are in agreement with theoretical predictions. The issue of integrating mental models theory with analyses of capacity limitations in performance is discussed. (shrink)

O presente texto visa a problematização do ensino de Filosofia na Educação Básica em um contexto de maior enquadramento do trabalho docente nas escolas públicas do estado de São Paulo. Argumenta-se que o poder educacional vem transformando as escolas em máquinas de fazer índices, em detrimento das experiências mínimas ou dos disparadores de pensamentos e afetos no cotidiano dos encontros aprendentes. Para tanto, mobilizam-se conceitos de Gilles Deleuze, Gilles Deleuze e Félix Guattari e Georges Didi-Huberman a fim de pensar as (...) possibilidades da Filosofia na escola. (shrink)

Recent studies have problematized on the lack of agreement between self-reported and proxied data in the field of road safety-related behaviors. Overall, and although these studies are still scarce, most of them suggest that the way we perceive our own road behavior is systematically different from the perspective from which we perceive others' behavior, and vice versa. The aim of this review paper was to target the number and type of studies that have researched the behavioral perceptions of different groups (...) of road users, contrasting self-reported behavioral data with those reported by other users, and their outcomes. This systematic review followed the PRISMA methodology, which allows for the identification of relevant articles based on the research term. A total number of 222 indexed articles were filtered, and a final selection of 19 articles directly addressing the issue was obtained. Search strategies were developed and conducted in MEDLINE, WOS, Scopus and APA databases. It is remarkable how road users perceive themselves as behaviorally “safer” than the rest of road users in what concerns the knowledge of traffic norms and their on-road performance. In addition, and regardless of the type of user used as a source, self-reported data suggest their perceived likelihood to suffer a traffic crash is lesser if compared to any other user. On the other hand, proxied reports tend to undervalue third users' performance, and to perceive riskier behaviors and crash-related risks among them. The outputs of this systematic review support the idea that the perception of road users' behavior and its related risks substantially differ according to the source. It is also necessary to increase the number, coverage and rigor of studies on this matter, perhaps through complementary and mixed measures, in order to properly understand and face the bias on road users' risk-related behaviors.

La exigencia ética es uno de los conceptos centrales del pensamiento de Kierkegaard. Él lo introduce como correctivo contra las tendencias nihilistas de su época. En este artículo se presentan los aspectos más importantes del desarrollo del concepto, partiendo del diagnóstico crítico de la modernidad que hace Kierkegaard y de su dialéctica de la comunicación ética y de su dialéctica de la comunicación ético-religiosa. La tesis central es que el amor, entendido como la exigencia radical hecha al individuo de superar (...) el egoísmo y ayudar al otro a ser independiente, posee un contenido normativo fuerte que fomenta el desarrollo positivo de las relaciones interpersonales.

En 1974, Robert Nozick publicó *Anarquía, Estado y Utopía*, una obra que, porprimera vez, otorgaba estatus teórico a una de las corrientes del pensamiento neoliberal:el libertarianismo. En buena medida, el texto de Nozick se reclama como una relectura enclave de filosofía analítica de la teoría política de John Locke. En este artículo se ofrecenalgunos argumentos para mostrar que, aunque la perspectiva de Nozick presenta ciertassimilitudes retóricas con la obra del filósofo inglés, en cada uno de los puntos fundamentales(como por ejemplo (...) la idea de derecho, la noción de persona, el papel de la política ylos conceptos de justicia y bien público) Nozick se aparta claramente de las premisas lockeanas.Como conclusión, se sostiene que al alejarse de la concepción lockeana, Nozickdefiende una sociedad en la que la política está ausente y en la que el Estado aparece,paradójicamente, menos limitado que en las concepciones liberales clásicas.
