Plato’s Statesman offers us interesting elements of his educational theory; it can be seen as a help towards attaining a greater knowledge of truth. This article begins with a brief introduction to this work, and then presents an analysis of several ideas that appear throughout the text, with a special emphasis on those dealing directly or indirectly with the theme of education and human communication. The article concludes with a summary of the main issues examined in the work.

The paper presents an exploration of conceptual issues that have arisen in the course of investigating speed-up and slowdown phenomena in small Turing machines, in particular results of a test that may spur experimental approaches to the notion of computational irreducibility. The test involves a systematic attempt to outrun the computation of a large number of small Turing machines (3 and 4 state, 2 symbol) by means of integer sequence prediction using a specialized function for that purpose. The experiment prompts (...) an investigation into rates of convergence of decision procedures and the decidability of sets in addition to a discussion of the (un)predictability of deterministic computing systems in practice. We think this investigation constitutes a novel approach to the discussion of an epistemological question in the context of a computer simulation, and thus represents an interesting exploration at the boundary between philosophical concerns and computational experiments.

This paper analyses Edith Stein's thought in order to find out, particularly in the investigation the philosopher did about Thomas Aquinas, the metaphysical assumptions hidden in the phenomeno-logy. It tries to clarify in which way the steinian "realism of essence", based on a certain logical atomism, gives up the idealistic postulates of Husserl's philosophy.

Resumen. En la presente investigación se describe el análisis de sentimiento realizado en comentarios publicados en la red social de Twitter. Los datos se obtuvieron al monitorear durante 36 días la evaluación del sentimiento de los comentarios que resultaron de hacer búsquedas de catorce diferentes sistemas operativos para celular; utilizando para dicha evaluación la herramienta Twitter-Sentiment. Se encontró que los comentarios positivos y negati¬vos presentan una correlación positiva para la mayoría de los sistemas operativos utilizados en la investigación.. The present (...) research describes the sentiment analysis carried on com¬ments published on the social network Twitter. The data were obtained by monitoring over 36 days of evaluation on the sentiment of the comments that resulted from querying four¬teen different mobile operating systems; using Twitter-Sentiment for the evaluation. It was found that the positive and negative comments have a positive correlation for most operating systems used in this research. (shrink)

Anankastic conditionals are analyzed in terms of events conceived as sequences of snapshots – roughly, comics. Quantification is applied not to worlds (sets of which are customarily identified with propositions) but to strings that record observations of actions. The account generalizes to other types of conditionals, sidestepping certain well-known problems that beset possible worlds treatments, such as logical omniscience and irrelevance. A refinement for anankastic conditionals is considered, incorporating action relations.

El artículo presenta un análisis de cuatro temas centrales de Sen: su visión sobre el ser humano, la libertad individual, la evaluación moral y los derechos, y la igualdad. Con esto quiero mostrar que estas ideas no sólo son consistentes, sino que explican muchas de las reflexiones sobre temas sociales y económicos que lo han convertido en un referente en estas áreas. En las conclusiones presentaré una síntesis e interpretación de estas ideas fundamentales, mostrando cómo constituyen un núcleo filosófico y (...) qué relaciones mantienen entre ellas. Mi objetivo no es encasillarlo en algunas de las corrientes de filosofía actuales, sino destacar la solidez y pertinencia de su aporte filosófico, algo sumamente útil en un tiempo como el nuestro, deseoso de ideas frescas para los acuciantes problemas de siempre.

In the paper, we will study Olavo de Carvalho’s thought, focusing on his position regarding Brazilian and American Black movement in its struggle for reparation in terms of colonialism-slavery-racism. We will argue that his refusal of any reparatory praxis to political-cultural minorities and his position of a non-place for Black-African traditions in the context of Western culture/civilization, as with respect to his defense of the inferiority of Black-African culture-civilization when compared to Jewish-Christian, Greek-Latin and Medieval-Renaissance tradition, is pervaded by a (...) dualist metaphysics with a highly anti-modern and anti-modernizing character, in which the dynamic of streamlining of “human drama about universe and eternity” is constituted by the struggle between natural necessity and individual consciousness, that can only be won by the correlation of divine grace given by Jesus Christ and personal direct and immediate interiorization and intuition by each individual with God; by the refusal of politics, history and intersubjective action as basically materialism and, in this sense, as the sphere of totalitarian political ideologies ; and, finally, by the centrality of spiritualism, of intimate and direct relation between God and man, mediated by Revelation, which points to the non-existence, in the Olavo de Carvalho’ thought, of objective parameters to rational discussion, interaction and justification – that is the reason of his delegitimation of science, politics, history and macro-structural institutional action, and his appeal to methodological, intuitionist and spiritualist individualism.

The nonreductionistic theory of the multiple aspects of reality offered by the Dutch philosopher Herman Dooyeweerd is employed to illuminate the status of bodies and biological entities in relation to attached and incorporated technological devices. I first present a review of the interpretations of the mechanization of biology and then argue from a Dooyeweerdian viewpoint that this mechanization also amounts to a reduction of the biotic aspect to previous aspects, such as the physical and the regulatory or cybernetic aspect. Next, (...) the irreducible meaning of the biotic aspect is defined as the vital life cycle and generational continuity that delineate the form of a species. Finally, I show how this definition helps us identify a normativity and a respect for living things, and I discuss its implications for bioengineering practices. (shrink)

A identificação e análise de princípios epistêmicos têm possibilitado ganhos significativos no estudo do ceticismo nas últimas décadas, isso não significa que estejamos próximos de um consenso sobre quais princípios devem ser aceitos. Entendendo p como qualquer proposição que geralmente admitiríamos saber, como “aqui há uma mão”, e sk como alguma proposição incompatível, como “estou sendo enganado por um gênio que me induz a crer em coisas que não existem”, o argumento canônico para o ceticismo acadêmico pode assim ser formalizado: (...) Se S está justificado ao crer que p, então S está justificado ao crer que ~sk; S não está justificado ao crer que ~sk, logo, S não está justificado ao crer que p. Implicitamente, pode-se notar: o cético advoga que a relação epistêmica tida com uma proposição deve ser preservada nas proposições decorrentes dessa e, uma vez falho o cumprimento dessa exigência, resulta-se inescapavelmente no ceticismo. Para resolver essa questão, alguns filósofos rejeitaram o ceticismo negando a premissa. Outros, como Klein, concedem ao cético, porém negam sua conclusão, apontando que este falha em sua defesa de. Discute-se aqui a viabilidade dessas alternativas. (shrink)

This book explores the notion of endangerment which stands at the heart of a network of concepts, values and practices dealing with objects considered threatened by extinction, and with the procedures aimed at preserving them. It looks at some of the fundamental ways in which this process involves science, but also more than science: not only data and knowledge and institutions, but also affects and values. With a focus on endangerment sensibility, it encapsulates tensions between the normative and the utilitarian, (...) the natural and the cultural. (shrink)

Con recurso a las filosofías de Heidegger y Gadamer, a las que ponemos a hablar con la teoría crítica, este artículo vuelve sobre el diálogo entre filosofía e historia. Cuando se leen estos dos autores en contraste con esa otra corriente de pensamiento, empiezan a hallarse resonancias e implicaciones mutuas, así como también las divergencias que se presentan. Desde esta confrontación pretendemos acceder a una consideración del tiempo y de la historia que permita elaborar desde allí una filosofía crítica. El (...) artículo hace productiva para una filosofía social las ontologías de la historicidad y del tiempo de Gadamer y Heidegger. (shrink)

Philosophy of Linguistics investigates the foundational concepts and methods of linguistics, the scientific study of human language. This groundbreaking collection, the most thorough treatment of the philosophy of linguistics ever published, brings together philosophers, scientists and historians to map out both the foundational assumptions set during the second half of the last century and the unfolding shifts in perspective in which more functionalist perspectives are explored. The opening chapter lays out the philosophical background in preparation for the papers that follow, (...) which demonstrate the shift in the perspective of linguistics study through discussions of syntax, semantics, phonology and cognitive science more generally. The volume serves as a detailed introduction for those new to the field as well as a rich source of new insights and potential research agendas for those already engaged with the philosophy of linguistics. It provides a bridge between philosophy and current scientific findings, encourages multi-disciplinary dialogue, and covers theory and applications. (shrink)

In this note we develop a method for constructing finite totally-ordered m-zeroids and prove that there exists a categorical equivalence between the category of finite, totally-ordered m-zeroids and the category of pseudo Łukasiewicz-like implicators.

Ethics in research are norms for conduct based on local regulations and universal recommendations such as the Nuremberg Code or the Declaration of Helsinki. However, these documents have a number of shortcomings that thwart the construction of a comprehensive ethical framework to guide research on humans in an effort to make better use of research results and to provide for ethical construction of knowledge. A broader ethical framework is suggested in this article, consistent with Ezekiel J. Emanuel's proposal, specifically one (...) that allows for evaluation, reflection and debate about scientific research on humans, based on eight fundamental principles. (shrink)

Este artículo supone la edición electrónica del libro homónimo publicado en 2006 por la editorial La Xara, de Simat de Valldigna (Valencia). Para los autores principales (filósofo e historiador) el estudio de las migraciones humanas se enfoca mejor desde la idea de ruta, cuyo análisis más potente se deriva, a su vez, del uso de categorías histórico-fenomenológicas, frente a otras posibles de menor rendimiento (sociológicas, psicológicas o metafísicas). Nos sitúan así en el ámbito de la filosofía de la historia. La (...) ruta es definida como una trayectoria que permite «unir y separar colectivamente (por contacto o contigüidad) sociedades, pueblos, culturas... y transformar así las relaciones entre los hombres, sus conocimientos sobre el mundo y los vínculos con las identidades que aún no se han incorporado a las rutas» (p. 29). Y la ruta es resultado incesante de la dialéctica entre las rutas históricas —del interior, religiosa, de la moneda, del desplazamiento, político-militar y de la energía—. Tales trayectorias y sus complementarias lanzan a la humanidad por el camino de la globalización. (shrink)

El autor analiza las principales características del liberalismo mexicano del siglo XIX. A través de la historia, el liberalismo ha adoptado diversos rostros, tanto en la doctrina como en la política. Sin embargo, esto no impide la existencia de configuraciones y procesos políticos similares en épocas y países distintos. A pesar de su carácter anóma-lo, el liberalismo mexicano del siglo XIX no corresponde a un orden social y político único. Debido al predominio, entre otros factores, de poderes locales, de intermediarios (...) políticos, de la falta de recursos y a un sentido pobre de cohesión social, el liberalismo mexicano tuvo que adoptar, paradójicamente, un carácter revolucionario.

Com o Sensualismo criam-se condições para uma nova estética, sensível e sensacionalista, que vai transformar as diversas artes (Literatura, Pintura, Escultura) e trazer consigo novas formas de espectáculo: o panorama, a fantasmagoria e o diorama (este, já no início do século XIX). O Eidophusikon, dispositivo de criação e ampliação (sensurround) de novas imagens – um híbrido de teatro e pintura, criado por Philippe de Loutherbourg entre 1781 e 1782 –, insere-se nesse processo e, com a fantasmagoria de Robertson (no final (...) do século XVIII, em França), constitui uma das modalidades do que hoje designamos por pré-cinema. No entanto, apropriando-se das novas condições de representação e de percepção do teatro introduzidas por David Garrick em Drury Lane – que promovem a “absorção” do espectador naquilo que vê em palco –, o Eidophusikon de Loutherbourg (ele próprio, pintor) pode ser considerado um elo em processo da nova concepção de pintura de Diderot – da qual a “promenade Vernet” do Salon de 1767 constitui como que a actualização por escrito.

The fast–slow paradigm of life history focuses on how individuals grow, mate, and reproduce at different paces. This paradigm can contribute substantially to the field of personality and individual differences provided that it is more strictly based on evolutionary biology than it has been so far. Our study tested the existence of a fast–slow continuum underlying indicators of reproductive effort—offspring output, age at first reproduction, number and stability of sexual partners—in 1,043 outpatients with healthy to severely disordered personalities. Two axes (...) emerged reflecting a double-track pathway to fast strategy, based on restricted and unrestricted sociosexual strategies. When rotated, the fast–slow and sociosexuality axes turned out to be independent. Contrary to expectations, neither somatic effort—investment in status, material resources, social capital, and maintenance/survival—was aligned with reproductive effort, nor a clear tradeoff between current and future reproduction was evident. Finally, we examined the association of LH axes with seven high-order personality pathology traits: negative emotionality, impulsivity, antagonism, persistence-compulsivity, subordination, and psychoticism. Persistent and disinhibited subjects appeared as fast-restricted and fast-unrestricted strategists, respectively, whereas asocial subjects were slow strategists. Associations of LH traits with each other and with personality are far more complex than usually assumed in evolutionary psychology. (shrink)

In view of the new forays from biology into the Humanities, this book aims not only to demonstrate the inconsistencies of the theory of evolution in addressing cultural dynamics, but also to offer an alternative that begins from a resumption of the dialogue between anthropology and historical materialism in which dialectics reintroduces itself to anthropology from different premises and the role of symbolic language within materialism is reevaluated.

L. Polo's doctrine of the first principles is analized focussing the study on causality as an indicator of the trascendentality of being and of its real distinction regarding essence. The concept of totality has its origins in the nonrealization of trascendental value of causality.
