In this research work a novel two-step system for anomaly detection is presented and tested over several real datasets. In the first step the novel Exploratory Projection Pursuit, Beta Hebbian Learning algorithm, is applied over each dataset, either to reduce the dimensionality of the original dataset or to face nonlinear datasets by generating a new subspace of the original dataset with lower, or even higher, dimensionality selecting the right activation function. Finally, in the second step Principal Component Analysis anomaly detection (...) is applied to the new subspace to detect the anomalies and improve its classification capabilities. This new approach has been tested over several different real datasets, in terms of number of variables, number of samples and number of anomalies. In almost all cases, the novel approach obtained better results in terms of area under the curve with similar standard deviation values. In case of computational cost, this improvement is only remarkable when complexity of the dataset in terms of number of variables is high. (shrink)

Can Artificial Intelligence be more effective than human instruction for the moral enhancement of people? The author argues that it only would be if the use of this technology were aimed at increasing the individual's capacity to reflectively decide for themselves, rather than at directly influencing behaviour. To support this, it is shown how a disregard for personal autonomy, in particular, invalidates the main proposals for applying new technologies, both biomedical and AI-based, to moral enhancement. As an alternative to these (...) proposals, this article proposes a virtual assistant that, through dialogue, neutrality and virtual reality technologies, can teach users to make better moral decisions on their own. The author concludes that, as long as certain precautions are taken in its design, such an assistant could do this better than a human instructor adopting the same educational methodology. (shrink)

Traditionally, the field of science and technology studies (STS) considered the scientific laboratory as the central site of knowledge production and technological development. While providing rich analyses of the social construction of scientific knowledge and the role of non-human actors, STS scholars have often neglected the university – the very context in which laboratories themselves are embedded – as a relevant object of research. In this paper, we argue for re-introducing the university as a relevant category and object of analysis (...) by using the notion of epistemic virtues to link epistemic culture – traditionally the focus of STS – and epistemic structure – traditionally the focus of higher education studies. Advancing this line of argumentation, we make three analytical moves. First, we explore academic freedom as a specific version of negative liberty that extends beyond disciplinary boundaries. We suggest that academics continuously negotiate academic freedom considering culturally and socially situated epistemic virtues such as objectivity and neutrality. Second, we introduce the notion of humility to revisit scientific knowledge production more generally and academic freedom in particular. Finally, we argue that practicing humility leads to enacting the university as an infrastructure of becoming otherwise, thereby enriching our understanding of universities as distinct and highly complex social spaces with a logic of their own.

Creating effective teamwork between humans and robots involves not only addressing their performance as a team but also sustaining the quality and sense of unity among teammates, also known as cohesion. This paper explores the research problem of: how can we endow robotic teammates with social capabilities to improve the cohesive alliance with humans? By defining the concept of a human–robot cohesive alliance in the light of the multidimensional construct of cohesion from the social sciences, we propose to address this (...) problem through the idea of multifaceted human–robot cohesion. We present our preliminary effort from previous works to examine each of the five dimensions of cohesion: social, collective, emotional, structural, and task. We finish the paper with a discussion on how human–robot cohesion contributes to the key questions and ongoing challenges of creating robotic teammates. Overall, cohesion in human–robot teams might be a key factor to propel team performance and it should be considered in the design, development, and evaluation of robotic teammates. (shrink)

Interpretations of Einstein’s equation differ primarily concerning whether E = mc2 entails that mass and energy are the same property of physical systems, and hence whether there is any sense in which mass is ever ‘converted’ into energy. In this paper, I examine six interpretations of Einstein’s equation and argue that all but one fail to satisfy a minimal set of conditions that all interpretations of physical theories ought to satisfy. I argue that we should prefer the interpretation of Einstein’s (...) equation that holds that mass and energy are distinct properties of physical systems. This interpretation also carries along the view that while most cases of ‘conversion’ are not genuine examples of mass being ‘converted’ into energy, it is possible that the there are such ‘conversions’ in the sense that a certain amount of energy ‘appears’ and an equivalent of mass ‘disappears’. Finally, I suggest that the interpretation I defend is the only one that does not blur the distinction between what Einstein called ‘principle’ and ‘constructive’ theories. This is philosophically significant because it emphasizes that explanations of Einstein’s equation and the ‘conversion’ of mass and energy must be top‐down explanations. (shrink)

a central thesis of martin heidegger's first reading of a Platonic dialogue, the 1924/25 course on the Sophist, was that, "for the Greeks, being means precisely to be present, to be in the present [Anwesend-sein, Gegenwärtig-sein]."1 Heidegger saw this Greek interpretation of being as leading to Plato's specific interpretation of being as eidos or idea. Heidegger makes this clear in the following passage from another Plato course, the 1931–32 course On the Essence of Truth: "'Idea' is the look [der Anblick] (...) of what something offers itself as being. These looks [Anblicke] are that in which the individual thing presents itself as this or that, that in which it is present and presencing [präsent und anwesend].... (shrink)

En sus análisis sobre la interioridad de la palabra en la hermenéutica de H. G. Gadamer, Jean Grondin afirma que su hermenéutica del vouloir-dire puede comprenderse como una "fenomenología de lo inaparente”. La afirmación deja establecido un vínculo entre la propuesta de Gadamer y esa polémica expresión que Heidegger usó para describir el sentido originario de la fenomenología. Hoy la fenomenología de lo inaparente se ha convertido en su motor a través del debate francés sobre el giro teológico. El objetivo (...) de este trabajo es examinar hasta qué punto esa formulación puede ser también motor de la hermenéutica de Gadamer. Para ello, se examinarán las condiciones de posibilidad e imposibilidad de tal acercamiento. (shrink)

The “destructive” appropriation of the Aristotelian concepts of δύναµις and ἐνέργεια played a central role in Martin Heidegger’s own reflection on the meaning of being. While this has been generally known for some time, it is only now that we can understand the full scope, complexity and evolving character of this appropriation. One reason is the fairly recent publication of notes and protocols for seminars Heidegger led on Aristotle as late as the 1940s and 1950s. Another is the existence of (...) student transcripts in the Special Collections Department of Stanford University for a number of unpublished seminars on Aristotle that Heidegger led during the 1920s. Considering all of this material enables us to see both the significance of Heidegger’s interpretation of the δύναµις/ἐνέργιεα pair as well as how this interpretation evolved along with his own “Kehre”: from a “pandynamic” conception of being to being as “Ereignis.”.

During the 1920s Heidegger gave no less than twelve seminars and lecture courses devoted either exclusively or in large part to the reading of Aristotle's texts. Seven of these, especially the smaller seminars for advanced students, have not been published and apparently will never be included in the Gesamtausgabe. My focus here is on the very first of these. Billed as a reading of Aristotle's De Anima, much of it was devoted to Aristotle's Metaphysics. This decision not to separate Aristotle's (...) “psychology” from his “ontology” is a key move of the seminar that anticipates the project of Being and Time. This and many other ways in which Heidegger's early reading of De Anima anticipates the key moves of the later book constitute one of the reasons for its importance. Another is that the seminar allows us to see what gets suppressed in Heidegger's reading of Aristotle, most significantly, the phenomenon of life itself in favor of an eventual focus on the being of human life or Dasein. This early seminar thus enables us not only to better understand Heidegger's project, but also to raise some fundamental questions concerning it. (shrink)

Pendant l’ete de 1928 Heidegger a offert un seminaire sur le troisieme livre de la Physique d’Aristote et donc sur l’explication aristotelicienne de la nature du mouvement. La derniere seance de ce cours, qui eut lieu le 25 juillet, est d’une grande importance parce que c’est a cette occasion que Heidegger va au livre neuf de la Metaphysique pour essayer de comprendre la notion ontologique qui est a la base de l’interpretation aristotelicienne du mouvement : l’energeia. Mais dans les protocoles (...) de ce seminaire qui se trouvent parmi les papiers de Heidegger et qui ont ete publies recemment dans le volume 83 de la Gesamtausgabe, la seance du 25 juillet se trouve absente. Ce fait a conduit l’editeur a conclure que le seminaire avait pris fin le 23 juillet, sans s’apercevoir donc que la conclusion du seminaire manquait. Il existe heureusement une transcription preservee parmi les papiers de l’etudiante de Heidegger, Helene Weiss, et accessible aujourd’hui dans les archives de l’universite de Stanford. Cette transcription montre que la derniere session eut bien lieu le 25 juillet et nous offre la lecture heideggerienne de Metaphysique IX qui ne se trouve pas dans la version de la Gesamtausgabe. C’est dans le contexte de cette lecture que Heidegger fait la declaration etonnante qui nous concerne ici : ≪Dans la derniere instance, la Metaphysique Θ revient a Platon ; la priorite de l’energeia est fondamentalement la meme chose que l’epekeina des Idees. ≫La première tâche que je me propose ici sera d’expliquer cette déclaration qui suggère une relation tres etroite, ou meme une identite, entre la notion aristotelicienne de l’energeia comme ayant une priorite vis‑a‑vis de la dunamis et la notion platonicienne de l’Idee du Bien comme etant epekeina de l’ousia. Pour cette explication je ferai appel non seulement au contexte du seminaire de 1928, mais aussi aux textes plus tardifs comme les Beitrage et les cours sur Nietzsche dans lesquels Heidegger semble presupposer et développer sa déclaration de 1928. Ma seconde tâche sera de comparer cette thèse heideggerienne a la tentative de Gadamer de surmonter l’opposition traditionnelle entre les ontologies de Platon et d’Aristote en faisant appel a l’idee du bien chez les deux. Cette tentative se trouve dans le texte Die Idee des Guten zwischen Plato und Aristoteles. La comparaison que j’entreprends ici va montrer certaines affinites entre les interpretations de l’Idee du Bien chez Heidegger et Gadamer, mais aussi de profondes differences qui vont determiner leurs differents projets philosophiques.

John Stuart Mill and Jeremy Bentham are often said to have held opposed views concerning the way “the value” of different pleasures should be estimated. Mill is accused of being an inconsistent utilitarian because he thought that, when comparing the value of two pleasures, we should not forget to take their “quality” into account. Bentham, on the other hand, is said to have believed that we should take “only quantity” into consideration. By verifying what they actually wrote, and reflecting on (...) what they meant by words like “value”, “quantity”, and “quality”, we find that these allegations are largely imaginary and that the difference between Mill and Bentham on this question has (at least) been exaggerated. Bentham, for example, did not write that "quantity of pleasure being equal, pushpin is as good as poetry", as is so often reported. In his Principles of Morals and Legislation he clearly tells us why he rejects the inaccurate word “quantity”, when speaking of “the value of (a lot of) pain or pleasure”, and he explicitly introduces “quality” – both the word and the concept – in his analysis of rewards and punishments. These clarifications allow us to sort-out a few other confusions concerning utilitarianism. We explain, for example, why authors like Amartya Sen and Michael Sandel are mistaken in believing that rights and freedoms have “no intrinsic value” (only instrumental value) in utilitarian ethics.

The essay reflects on the harmful effect that recourse to post-truth (modern form of political lie) supposes for democracy. Taking Hannah Arendt's thought as a reference, the Author analyzes the role that truth plays in the political sphere and the recourse to lying as a mode of domination by totalitarian political systems where reality constitutes an uncomfortable fact. Opposite with these systems, democracies try to preserve the autonomy of citizens to shape their political preferences, in a context dominated by reason (...) and truth, against the deformations of reality generated by the use of emotions and lies.

El presente ensayo explora el itinerario de la crítica que Nietzsche ejerció sobre el arte de Wagner en tres pasos. Primero, se trata de reconocer la juvenil admiración del filósofo por la ópera wagneriana entendida como un renacimiento del drama musical antiguo. Luego, se explora el tránsito hacia su desilusión en la clave de la influencia de Schopenhauer sobre Wagner. Finalmente, el ensayo remata en la crítica madura de Nietzsche sobre Wagner, donde se advierten los prolegómenos decimonónicos de la transformación (...) general del arte en espectáculo en el sentido contemporáneo.

Este artigo problematiza, sob o ponto de vista teórico da Análise do Discurso francesa, por que, em algumas regiões do Nordeste brasileiro, há quem evite pronunciar a palavra macaco e opte por usar em seu lugar outras palavras, tais como dezessete. A hipótese defendida é a de que essa prática cultural-discursiva, entendida aqui como uma forma de interdição, ocorre basicamente em regiões sertanejas onde a memória do cangaço é ainda marcadamente diluída no cotidiano. A partir da análise de discursos presentes (...) no dia a dia, este artigo pretende contribuir para uma compreensão mais acurada de uma particularidade sociocultural brasileira. (shrink)

El Furry Fandom es una subcultura en torno al interés por animales o criaturas antropomórficas, pero apenas ha sido investigada su población hispanohablante, a pesar de la instigación de los medios de comunicación españoles reproduciendo estereotipos de los medios americanos. El artículo aborda cómo se construye la identidad furry en España y sus relaciones con la práctica del género (regulada sexualmente); así como el uso de jerga. El método consta de observación participante en foros y en entrevistas para análisis de (...) casos; lo cual permitió un análisis de contenidos diversos, repertorios interpretativos y un análisis crítico del discurso . Como conclusión, el furry fandom enmarca cuestiones feministas a partir de la metáfora del cyborg, tales como qué papel debe tener la ciencia, ideología sobre la naturaleza humana y la necesidad de coalición de identidades.

Hospitality can be considered a key institution in the social relationships in the ancient Mediterranean. To identify the people involved in a hospitality agreement, in certain contexts small objects were used in a similar way to a password, which the Greeks called symbolon and the Romans tessera hospitalis. We know how the latter were used thanks to Plautus' Poenulus. At least 64 pieces are currently known which may be identified as tesserae hospitales. All come from the Western Mediterranean. The majority (...) contain brief inscriptions, written in Etruscan, Latin, Greek, or Celtiberian. They share a series of common features, which impart a clear family resemblance beyond geographic, cultural, or linguistic borders. (shrink)

In the history of literary criticism the name of Ortega y Gasset is indispensable, since in this, as well as in all other sectors of cultural activity, the influence of his thought has been most decisive. He opened paths and established guidelines that remain in effect; his vision of the Quijote not only counterbalanced that of Unamuno, against which it purposely rebelled, but also, by underscoring the resources called into play by Cervantes in composing his master work, he has shaped (...) the attitudes of subsequent professional and academic criticism; and his analysis of the personalities of such important writers as Baroja is as yet unsurpassed. Among his many influential works, Francisco Ayala has written Reflexiones sobre la estructura narrativa (criticism) and España, a la fecha. (essays). His collected fiction appeared in 1969 under the title Obras narrativas completas. At Professor Ayala's request, this essay, and Ideas sobre Pío Baroja, by José Ortega y Gasset, were translated by Richard Ford. (shrink)

The design of the bronchial tree has largely been proposed as a model of optimal design from a physical-functional perspective. However, the distributive function of the airway may be more related to a geometrical than a physical problem. The bronchial tree must distribute a three dimensional volume of inspired air on a two dimensional alveolar surface, included in a limited volume. It is thus valid to ask whether an optimal bronchial tree from a physical perspective is also optimum from a (...) geometrical point of view. In this paper we generate a simple geometric model for the branching pattern of the bronchial tree, deducing relationships that permit estimation of the departures from the geometrical optimum of each bifurcation. We also, for comparative purposes, estimate the departures from the physical optimum. From the geometrical assumptions: i) a symmetrical dichotomic fractal design, ii) with minimum volume and iii) maximum dispersion of the terminal points; and several simulations we suggest that the optimality is characterized by a bifurcation angle Θ ∼ 60° and a length reduction scale γ = (1/2)1/3 = 0.7937. We propose distances from the physical and geometrical optimality defined as Euclidean distances from the expected optima. We show how the advanced relationships and the distances can be used to estimate departures from the optimality in bronchographs of four species. We found lower physical and geometrical departures in the distal zone than those of the proximal zones, as well as lower physical than geometrical departures from optimality. (shrink)

Either God or nothing – Nihilism and transcendental Idealism. By the time of the “Atheism-Controversy” (Atheismusstreit) Jacobi wrote a “Letter to Fichte” (Brief an Fichte) in which he described the doctrine of science as Nihilism and not as Atheism. According to Jacobi, the doctrine of science would incur in to an emptiness of meaning and in to an artificial belief. Nevertheless, Fichte’s first and immediate position towards those critiques was not one of perplexity, because according to him the critiques Jacobi’s (...) on the doctrine of science were in fact to be understood as a confusion between life and philosophy. The aim here is to discuss the distinction Fichte’s between the point of view of life and the one of the philosophy. This contribution isn’t however based only on texts that approach this distinction, but also analyses it in an illustrative way by interpreting some speculative writings of Fichte himself, specially the published exposition of his doctrine of science: the Grundlage der gesamten Wissenschaftslehre. Those texts apparently reinforce Jacobi’s position, but show in fact that Fichte is right. This way it may possible to reach a clear description of transcendental idealism, or at least as it was presented by Fichte in his Jena-period (1794–99). Anlässlich des Atheismusstreits schreibt Jacobi einen Brief An Fichte, in dem er die Wissenschaftslehre nicht als Atheismus, sondern als Nihilismus darstellt. Jacobi zufolge würde die Wissenschaftslehre an eine Sinnentleerung und an einen künstlichen Glauben verfallen. Die erste und unmittelbare Stellungnahme Fichtes gegenüber diesen Kritiken ist allerdings nicht durch Betroffenheit gekennzeichnet, weil diese Kritiken Jacobis an der Wissenschaftslehre, so Fichte, sich durch eine Verwirrung zwischen Leben und Philosophie erklären lassen. Hier geht es folglich darum, diese methodologische Unterscheidung zwischen dem Standpunkt des Lebens und dem der Philosophie zur Diskussion zu stellen. Dieser Beitrag lässt sich aber nicht nur durch eine Bezugnahme auf die Texte, die sich allein mit dieser Unterscheidung auseinandersetzen, begründen, sondern auch illustrativ, d.h. durch die Bewertung einiger spekulativen Texte Fichtes, im Besonderen seine veröffentlichte Darstellung der Wissenschaftslehre: die Grundlage der gesamten Wissenschaftslehre. Solche Texte bestärken nur anscheinend Jacobis Position, deuten aber tatsächlich, dass Fichte eigentlich Recht hat. Dadurch lässt sich vielleicht eine hervortretende Beschreibung des transzendentalen Idealismus gewinnen, wenigstens wie er sich bei Fichte in der Jenaer Zeit (1794–99) darstellte. (shrink)

Koselleck en su escrito Futuro Pasado, considera que la historia conceptual permite la comprensión del pensamiento socio-político ya que los conceptos son las herramientas con las que los actores de un momento histórico articularon sus estructuras socio-políticas, y proyectaron diversas expectativas sobre su futuro. Por otra parte, la implementación de la historia conceptual en el estudio del pensamiento socio-político latinoamericano, ofrece a la historia social y a la filosofía política una nueva mirada sobre la consolidación, el cambio o desaparición de (...) las sociedades, sus instituciones y sus conceptos políticos fundamentales. Ahora bien, en este escrito presento una aproximación sobre la libertad y su importancia como concepto fundamental del pensamiento socio-político, en el periodo de la Regeneración, en tres momentos. Primero, describo los lineamientos generales de la historia conceptual. Segundo, expongo la influencia de la historia conceptual en el estudio del pensamiento socio-político latinoamericano. Finalmente, establezco las posibilidades del análisis del concepto libertad durante el periodo de la Regeneración. (shrink)

ABSTRACTThe important role played by Aristotle in Martin Heidegger’s path towards Being and Time during the 1920's is now well documented. Yet an important chapter of this story remains mostly unexplored: Heidegger's early attempt to develop an ontology of life in dialogue with Aristotle. This is because the early seminars in which Heidegger developed his important and highly original interpretation of Aristotle's De Anima remain unpublished : one seminar from the summer of 1921 and one spanning the winter semester of (...) 1922/23 and the summer semester of 1923. In the present paper, I reconstruct Heidegger's key interpretative moves in the latter seminar on the basis of a detailed handwritten transcript preserved among the papers of his student Helene Weiss held at Stanford University. What emerges is a dialogue between Aristotle and Heidegger that enables us better to understand and to question the thought of both philosophers on the phenomenon of life. (shrink)

This paper defends a ‘perspectivist’ reading of Plato’s dialogues. According to this reading, each dialogue presents a particular and limited perspective on the truth, conditioned by the specific context, aim and characters, where this perspective, not claiming to represent the whole truth on a topic, is not incompatible with the possibly very different perspectives found in other dialogues nor, on the other hand, can be subordinated or assimilated to one of these other perspectives. This model is contrasted to the other (...) models that have been proposed, i.e., Unitarianism, Developmentalism, and ‘Prolepticism’, and is shown to address and overcome the limitations of each. One major advantage of ‘perspectivism’ against the other interpretative models is that, unlike them, it can do full justice to the literary and dramatic character of the dialogues without falling into the opposite extreme of turning them into literary games with no positive philosophical content. To say that Plato’s dialogues are ‘perspectivist’ is not to say that they contain no ‘doctrines’ on the soul, for example, but, on the contrary, to stress the plurality of doctrines, with the observation that each is true within the limits of the argumentative function it is introduced to serve and of the specific dialogical context.

In modern political science, repeated elections are considered as the main mechanism of electoral accountability in democracies. More rarely, elections are considered as ways to select ‘good types’ of politicians. In this article it is argued that historical republican authors interpreted elections in this last sense. They viewed elections as a means to select what they often called the ‘natural aristocracy’, virtuous political leaders who would pursue the common good. This argument is presented in three steps. First, it is claimed (...) that republican authors did not consider retrospective accountability as one of the goals of electoral processes. Second, I present some evidence concerning the distinction in republican authors between two types of politicians, ‘good’ and ‘bad’. And, finally, I present some republican arguments about how elections could serve as a device for selecting the ‘good’ politicians. (shrink)
