Algunas notas tomadas a partir de las expli­caciones orales de Damascio sobre el _Filebo _de Platón permiten aproximarse a la comprensión del Bien en un contexto neoplatonizante. Damascio acentúa el parale­lismo entre el proceder dialéctico y la distribución par­cializada de la _Unidad_. El método de la división conduce hasta lo triádico que enlaza en un Mixto la dualidad de Límite e Ilimitado. Verdad, belleza y proporción concilian la dispersión de la pluralidad y encaminan hacia lo incognoscible del Bien. Lo deseable, (...) lo suficiente y la plenitud de la perfección explicitan las vías a transitar, cuando recuperan anímicamente el dinamismo propio de Ser-Vida-Intelecto. (shrink)

The distinctive security features of the Spanish electronic national identity card, known as Documento Nacional de Identidad electrónico, allow us to propose the usage of this cryptographic smart card in an authentication framework that can be used during the registration and login phases of internet services where the validation of the user’s age and real identity are key elements, as it is the case for example of the so-called social networks. Using this mechanism with NFC-capable devices, the identity and age (...) of the potential user can be determined, allowing or denying the access to the service based on that information. (shrink)

In this paper we enrich the orthomodular structure by adding a modal operator, following a physical motivation. A logical system is developed, obtaining algebraic completeness and completeness with respect to a Kripkestyle semantic founded on Baer*-semigroups as in [22].

In this article we discuss the contextual character of quantum mechanics in the framework of modal interpretations. We investigate its historical origin and relate contemporary modal interpretations to those proposed by M. Born and W. Heisenberg. We present then a general characterization of what we consider to be a modal interpretation. Following previous papers in which we have introduced modalities in the Kochen-Specker theorem, we investigate the consequences of these theorems in relation to the modal interpretations of quantum mechanics.

El objetivo de este artículo es analizar la representación cinematográfica de las residencias para personas mayores. Recurrimos al método hermenéutico comparado para analizar cuatro películas de habla hispana estrenadas entre 2010 y 2020: Arrugas, El agente topo, La plaga y Quien a hierro mata. El análisis de resultados se fundamenta en un análisis temático inductivo, mediante la categorización e identificación de temas recurrentes en las tramas que analizamos desde planteamientos de la sociología y gerontología social. Argumentamos que la representación de (...) las residencias en estas películas entraña, en diferentes grados, tendencias contrapuestas de reproducción y problematización de imaginarios estigmatizantes propios del nursing home specter. Por un lado, las narrativas privilegian la reproducción de un imaginario que asocia las residencias al abandono, la soledad y los malos cuidados, reforzando el ideal de cuidados familista que caracteriza a la sociedad española. Por otro, identificamos secuencias que evidencian la potencialidad del cine para problematizar estereotipos y profundizar en la comprensión de realidades complejas. Estos imaginarios cinematográficos cobran mayor relevancia en el actual contexto de replanteamiento del modelo residencial. (shrink)

The latest advances in quantum computing forced the National Institute of Standards and Technology (NIST) to launch an initiative for selecting quantum-resistant cryptographic algorithms. One of the best-known proposals is NewHope, an algorithm that was initially designed as a key exchange algorithm. In its original design, NewHope presented a reconciliation mechanism that is complex and represents an entry barrier for potential implementers. This contribution presents equivalent schemes in one, two and three dimensions, which allow anyone to make the transition to (...) the 4D NewHope algorithm easier to undertake. In addition to that, the effect of modifying some of the parameters associated to NewHope’s reconciliation mechanism is studied, which has allowed us to propose different sets of parameters that could increase the security of NewHope implementations.

Graciela De Pierris presents a novel interpretation of the relationship between skepticism and naturalism in Hume's epistemology, and a new appraisal of Hume's place within early modern thought. Contrary to dominant readings, she argues that Hume does offer skeptical arguments concerning causation and induction in Book I, Part III of the Treatise, and presents a detailed reading of the skeptical argument she finds there and how this argument initiates a train of skeptical reasoning that begins in Part III and (...) culminates in Part IV. She goes on to demonstrate that Hume was committed to the Newtonian inductive method while rejecting the place of the supernatural in our understanding of nature. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 351-383 [Access article in PDF] Hume's Pyrrhonian Skepticism and the Belief in Causal Laws Graciela De Pierris Hume endorses in no uncertain terms the normative use of causal reasoning. The most striking example of this commitment is Hume's argument in the Enquiry against the possibility of miracles. The argument sanctions, in particular, the use of scientific reflection on uniform experience (...) issuing in causal laws of nature (E 114): "A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined." 1 These words should give us pause; for how can Hume so confidently say, after his skeptical conclusions concerning our causal beliefs, that "a firm and unalterable experience has established" the laws of nature, and that we can therefore produce "proofs" against miracles? The Treatise gives rise to the same puzzle. In this text, too, Hume confidently prescribes methodical reflection based on causal reasoning. For example, in Book One, Part Three, Section Fifteen, Hume offers eight "Rules by which to judge of causes and effects." These rules are more than descriptions of our natural causal inferences. They are meant to guide us in making better causal inferences; in Hume's words they "ought to regulate" our probable reasoning since (T 149): "by them we learn to distinguish the accidental circumstances from the efficacious causes." 2Moreover, Hume consistently takes Newtonian science as a model for the proper employment of causal inferences in inquiries into matters of fact and, [End Page 351] in particular, as a model to be followed in his own science of human nature. 3 This paradigm of what the science of nature ought to be is understood by Hume as an inductive, experimental inquiry. 4 In the Enquiry, for example, Hume uses the label "sciences" for "politics, natural philosophy, physic, chemistry, &c." and in the preceding discussion argues that these sciences are not a priori but are based on causal reasoning (E 164-165). Thus, there are for Hume inquiries into matters of fact and existence that amount to more than blindly following natural propensities and habit. The sciences and many of our causal inferences in common life involve more than mere belief as a sentiment. They involve, in addition, careful reflection that results in improved causal inferences and thus provides normative standards. Yet, in thus upholding the normative use of causal reasoning in science and in everyday life, Hume appears to contradict his own radical skeptical conclusions concerning our knowledge of causation and induction. I here propose a novel way to resolve this puzzle.To acknowledge the existence of a puzzle, however, amounts to accepting the now controversial view that Hume provides, and takes at face value, a radical skeptical argument concerning our knowledge of causation and induction. 5 Moreover, the attempt to resolve this puzzle involves rejecting the suggestion [End Page 352] that Hume, without awareness or concern, happily holds flatly inconsistent views. 6 It also goes against the more sophisticated suggestion that Hume lightly alternates among different psychological moods, or perhaps different perspectives, which might eventually issue in results that contradict each other but are sufficiently localized so as to prevent serious conflict. Such a view might lead us to conceive Hume's texts as an unstructured and arbitrary patchwork of reflections, driven by different psychological moods or by the embellishments of a radiant literary style. This kind of reading is unacceptable as an interpretative tool, however, as H. J. Paton has acutely noted in his criticism of the patchwork interpretation of Kant's Critique of Pure Reason. 7 For such a reading would place no constraints at all on the task of establishing which parts of Hume's text belong to which moods or perspectives. The suggestion that Hume offers an unstructured patchwork of reflections masks the novel and systematic distinction Hume draws between his radical philosophical... (shrink)

Hume’s discussion of space, time, and mathematics at T 1.2 appeared to many earlier commentators as one of the weakest parts of his philosophy. From the point of view of pure mathematics, for example, Hume’s assumptions about the infinite may appear as crude misunderstandings of the continuum and infinite divisibility. I shall argue, on the contrary, that Hume’s views on this topic are deeply connected with his radically empiricist reliance on phenomenologically given sensory images. He insightfully shows that, working within (...) this epistemological model, we cannot attain complete certainty about the continuum but only at most about discrete quantity. Geometry, in contrast to arithmetic, cannot be a fully exact science. A number of more recent commentators have offered sympathetic interpretations of Hume’s discussion aiming to correct the older tendency to dismiss this part of the Treatise as weak and confused. Most of these commentators interpret Hume as anticipating the contemporary idea of a finite or discrete geometry. They view Hume’s conception that space is composed of simple indivisible minima as a forerunner of the conception that space is a discretely (rather than continuously) ordered set. This approach, in my view, is helpful as far as it goes, but there are several important features of Hume’s discussion that are not sufficiently appreciated. I go beyond these recent commentators by emphasizing three of Hume’s most original contributions. First, Hume’s epistemological model invokes the “confounding” of indivisible minima to explain the appearance of spatial continuity. Second, Hume’s sharp contrast between the perfect exactitude of arithmetic and the irremediable inexactitude of geometry reverses the more familiar conception of the early modern tradition in pure mathematics, according to which geometry (the science of continuous quantity) has its own standard of equality that is independent from and more exact than any corresponding standard supplied by algebra and arithmetic (the sciences of discrete quantity). Third, Hume has a developed explanation of how geometry (traditional Euclidean geometry) is nonetheless possible as an axiomatic demonstrative science possessing considerably more exactitude and certainty that the “loose judgements” of the vulgar.

Background During the first weeks of March 2020 in Spain, the cases of severe respiratory failure progressively increased, generating an imbalance between the clinical needs for advanced life support (ALS) measures and the effective availability of ALS resources. To address this problem, the creation of triage committees (TC) was proposed, whose main function is to select the best candidates to receive ALS. The main objective of our study is to describe the clinical characteristics of the patients evaluated by the TC (...) of the Alcorcón Foundation University Hospital (AFUH) during the first wave of SARS CoV-2. Other objectives are to determine if there are differences between the patients considered candidates / not candidates for ALS and to analyze the functioning of the TC. Methods Retrospective observational study of all patients assessed by the AFUH TC. Results There were 19 meetings, in which 181 patients were evaluated, 65.4% male and with a mean age of 70.1 years. 31% had some degree of functional dependence, the Barthel median was 100 and Charlson 4. 58.5% were not considered a candidate for ALS at that time. The patients considered candidates to receive ALS were younger (72 vs 66; _p_ Conclusions The patients evaluated by the TC had a mean age of 70 years, high comorbidity and almost a third had some degree of functional dependence. More than half were not considered candidates for ALS at that time, these patients being older, with more comorbidity and a worse previous functional situation. TC decisions, based on objective clinical criteria, were almost always respected. Public institutions must get involved in triage procedures, which should and in our opinion must include the creation of TC in health centers. The implementation of Anticipated Decision programs (ADP) would help enable patients affected by triage decisions to participate in them. (shrink)

In this paper we attempt to physically interpret the Modal Kochen–Specker theorem. In order to do so, we analyze the features of the possible properties of quantum systems arising from the elements in an orthomodular lattice and distinguish the use of “possibility” in the classical and quantum formalisms. Taking into account the modal and many worlds non-collapse interpretation of the projection postulate, we discuss how the MKS theorem rules the constraints to actualization, and thus, the relation between actual and possible (...) realms.

Hume follows Newton in replacing the mechanical philosophy’s demonstrative ideal of science by the Principia’s ideal of inductive proof ; in this respect, Hume differs sharply from Locke. Hume is also guided by Newton’s own criticisms of the mechanical philosophers’ hypotheses. The first stage of Hume’s skeptical argument concerning causation targets central tenets of the mechanical philosophers’ conception of causation, all of which rely on the a priori postulation of a hidden configuration of primary qualities. The skeptical argument concerning the (...) causal inductive inference then raises doubts about what Hume himself regards as our very best inductive method. Hume’s own “Rules” further substantiate his reliance on Newton. Finally, Locke’s distinction between “Knowledge” and “Probability” does not leave room for Hume’s Newtonian notion of inductive proof.

By giving the proper emphasis to both radical skepticism and naturalism as two independent standpoints in Hume, I wish to propose a more satisfactory account of some of the more puzzling Humean claims on causation. I place these claims alternatively in either the philosophical standpoint of the radical skeptic or in the standpoint of everyday and scientific beliefs. I characterize Hume’s radical skeptical standpoint in relation to Hume’s perceptual model of the traditional theory of ideas, and I argue that Hume‘s (...) radical skeptical argument concerning our causal inferences is inextricably linked to his skeptical argument concerning our idea of a necessary connection between cause and effect. I discuss Hume’s naturalistic account of the origin of our idea of necessity and offer a new reading of Hume’s two “definitions” of cause. I argue along the way against central aspects of two opposing styles of interpretation---Norman Kemp Smith’s and Annette Baier’s, on the one hand, and Robert Fogelin’s, on the other---that in my view do not appreciate the mutual autonomy of radical skepticism and naturalism in Hume.

In this paper we analyze and discuss the historical and philosophical development of the notion of logical possibility focusing on its specific meaning in classical and quantum mechanics. Taking into account the logical structure of quantum theory we continue our discussion regarding the Aristotelian Square of Opposition in orthomodular structures enriched with a monadic quantifier. Finally, we provide an interpretation of the Orthomodular Square of Opposition exposing the fact that classical possibility and quantum possibility behave formally in radically different manners.

The COVID-19 virus was unveiled to the world as a health crisis and later also as an economic crisis. For some organisations, it has become an ethical crisis. This is certainly the case for large organisations in Australia, where the way many enterprises handled a government wage subsidy called JobKeeper led to a public backlash, media pressure, and a variety of responses ranging from ‘We acted legally’ to the full return of the subsidy. Some organisations later reported profits, and the (...) public response indicated concern about this behaviour, many considering it immoral despite it being legally compliant. It is, we contend, a question to which stakeholder theory can be applied, examining how organisations view and respond to the public. We use content analysis of mainstream media to provide information about public reactions and information from official sources to confirm corporate action. We show that there is a significant ethical component in the public response to the behaviour of organisations as they respond to the crisis. COVID has been an ethical, health, and financial crisis for these organisations. Public pressure, exerted in and through the media, made the general public a definite stakeholder. (shrink)

The modem rationalist tradition initiated by Descartes has as one of its central tenets the independence of the human understanding from the senses. Regardless of the different ways in which independence from experience is understood, there is much common ground among the modem views on the a priori. Yet Kant, culminating this tradition, introduces an entirely new conception of the a priori never before articulated in the history of philosophy. This is the notion of elements in knowledge which are independent (...) of experience but nevertheless closely connected, in a special way, with experience.Although for Kant the a priori has a privileged position in the structure of knowledge - as it has for other modem rationalist philosophers - one of the most striking, and often neglected, aspect of his conception of the a priori is the great extent to which it is opposed to foundationalism.

The objective of the work is to analyze the intersectional discriminations that operate in the multiple identities of regional migrant women in the field of health in Argentina during the present pandemic. We will begin with the critical study of key categories and the origin of the inequalities of law of the aforementioned discrimination in migration policies. Second, we will address de facto inequalities, particularly examining the socio-economic inequalities suffered by migrants during the pandemic. Thirdly, in order to enable alternative (...) forms of care and self-care from the recognition of their ethnicity and the inseparable care of the earth, we propose the application of the concept of territorial participatory justice as a condition of intercultural dialogue in health. As a proposal, it seeks to promote dialogues of knowledge located outside the bureaucratic councils and expanding the social base of health rights from the pluriculturality exercised in care networks of migrant women in the territory and not from their domesticated participation.

O presente estudo acerca das atividades praticadas por rezadeiras no Brasil teve o intuito de identificar as identidades étnicas e as etnociências que compõem a pluralidade dos grupos sociais nos quais elas atuam e qual a sua importância para os meios. O objetivo, portanto foi identificar as diferentes identidades étnicas que influenciam as práticas das rezadeiras. Para isso, foi adotada a metodologia da pesquisa bibliográfica de cunho exploratório descritivo e qualitativa a fim de obter uma visão sistemática do assunto. O (...) estudo se justifica devido a importância em conhecer as identidades éticas bem como a etnociência existente nas práticas das rezadeiras, resgatando conhecimentos históricos e uma riqueza cultural fundamental para boa parte da população brasileira uma vez que estudos na área são escassos. Foram analisados 15 artigos que pautam sobre as práticas das rezadeiras, e os resultados obtidos apontaram que há muitas semelhanças entre as práticas de rezadeiras em diferentes regiões do Brasil e suas diferenças estão relacionadas, provavelmente, às origens que esses povos possuem. Portanto, conclui-se que vieram de matrizes africanas e indígenas principalmente e que possuem ainda mais semelhanças devido ao intercâmbio realizado entre algumas dessas culturas no território brasileiro.

En República, libro X, Platón justifica su exclusión de la poesía imitativa mediante argumentos metafísicos y psicológicos. Al hacerlo, enfatiza la distancia de los productos de la imitación respecto de la verdad, y los condena porque apelan al elemento inferior del alma. En Sofista 233d- 236c, se propone una crítica similar contra la sofistería. El imitador puede hacer eidola, que puede ser considerado como real por un ignorante. En ambos casos Platón se refiere a la distancia respecto de la verdad (...) que guardan tanto los objetos hechos por los imitadores –pintores, poetas o sofistas– como los destinatarios de tales artes –espectadores u oyentes–. Los paralelismos entre ambos tratamientos son abundantes. Tal «distancia», como tratamos de mostrar, ofrece una clave no sólo para entender la crítica platónica de la mímesis, sino que también arroja luz sobre algunos pasajes de República cuya conexión con el tratamiento de la imitación no es evidente de inmediato: la sección eikasía de la «línea dividida», así como ciertos pasajes de la alegoría de la caverna. Ambos textos, independientemente de las variadas lecturas e interpretaciones que han merecido, aclaran la naturaleza de la mimesis y las críticas de Platón contra ella. Además, testifican la confianza de Platón en que el contacto directo con lo real neutraliza los efectos perniciosos de la imitación Palabras clave: Mímesis; Verdad; DistanciaIn Republic Book X, Plato justifies his exclusion of imitative poetry by means of metaphysical and psychological arguments. In doing that, he emphasizes the distance from truth of the products of imitation, and condemns them because they appeal to the lower element of the soul. In Sophist 233d-236c, a similar critique is directed against sophistry. The imitator can make eidola, which can be taken by an ignorant as being real. In both cases Plato refers to the distance that both the objects made by imitators –painters, poets or sophists– and the recipients of such arts –spectators or auditors– have from truth. The parallelisms between both treatments are abundant. Such «distance», as we try to show, offers a key not only to understand Platonic criticism of mimesis. It also throws light on some passages of Republic whose connection with the treatment of imitation is not immediately evident: the eikasía section of the «divided line», and certain passages of the allegory of the cave. Both texts, independently of the various readings and interpretations they have deserved, clarify the nature of mimesis and Plato’s criticisms against it. In addition, they testify Plato’s confidence that direct contact with the real neutralizes the pernicious effects of imitation. Keywords: Mimesis; Truth; Distance. (shrink)

En primer lugar, se contrapone la ambigüedad a la ambivalencia en razón de que ésta no nos permite alcanzar intelecciones claras, se diferencian sus dos sentidos -existencial y conceptual-, y se señala su asociación con la dialéctica. Luego el artículo continúa con el examen de las ambigüedades que caracterizaa (...) la relación entre cuerpo y espíritu,lenguaje y espíritu, e historia y coexistencia.Por último, se intenta mostrar la perspectiva para el humanismo que surge de una situación en que la contingencia tiene un papel decisivo, de modo que ningún principio explicativo puede eliminar las dificultades o la opacidad en la interacción social.

In this paper, I discuss the current thesis on the modern origin of the ad hominem-argument, by analysing the Aristotelian conception of it. In view of the recent accounts which consider it a relative argument, i.e., acceptable only by the particular respondent, I maintain that there are two Aristotelian versions of the ad hominem, that have identifiable characteristics, and both correspond to the standard variants distinguished in the contemporary treatments of the famous informal fallacy: the abusive and the circumstancial or (...) tu quoque types. I propose to reconstruct the two Aristotelian versions (see sections 1 and 2), which have been recognized again in the ninteenth century (sec. 3). Finally, I examine whether or not it was considered as a fallacious dialogue device by Aristotle and by A. Schopenhauer (sec. 4). (shrink)
