Here, we deal with the question of under which circumstances can scientists achieve a legitimate understanding of defective theories qua defective. We claim that scientists understand a theory if they can recognize the theory’s underlying inference pattern(s) and if they can reconstruct and explain what is going on in specific cases of defective theories as well as consider what the theory would do if non-defective –even before finding ways of fixing it. Furthermore, we discuss the implications of this approach to (...) understanding the meta-metaphysics of Quantum Mechanics, specifically with regard to Quasi-set theory. We illustrate this by employing Quasi-set theory to structure a defective scientific theory and make possible the understanding of the theory. (shrink)

BackgroundUmbilical cord banks are a central component, as umbilical cord tissue providers, in both medical treatment and scientific research with stem cells. But, whereas the creation of umbilical cord banks is seen as successful practice, it is perceived as a risky style of play by others. This article examines and discusses the ethical, medical and legal considerations that arise from the operation of umbilical cord banks in Mexico.DiscussionA number of experts have stated that the use of umbilical cord goes beyond (...) the mere utilization of human tissues for the purpose of treatment. This tissue is also used in research studies: genetic studies, studies to evaluate the effectiveness of new antibiotics, studies to identify new proteins, etc. Meanwhile, others claim that the law and other norms for the functioning of cord banks are not consistent and are poorly defined. Some of these critics point out that the confidentiality of donor information is handled differently in different places. The fact that private cord banks offer their services as "biological insurance" in order to obtain informed consent by promising the parents that the tissue that will be stored insures the health of their child in the future raises the issue of whether the consent is freely given or given under coercion. Another consideration that must be made in relation to privately owned cord banks has to do with the ownership of the stored umbilical cord.SummaryConflicts between moral principles and economic interests (non-moral principles) cause dilemmas in the clinical practice of umbilical cord blood storage and use especially in privately owned banks. This article presents a reflection and some of the guidelines that must be followed by umbilical cord banks in order to deal with these conflicts. This reflection is based on the fundamental notions of ethics and public health and seeks to be a contribution towards the improvement of umbilical cord banks' performance. (shrink)

The present study explores the application of advanced statistical techniques to predict the academic performance of students in the area of mathematics. Through the use of logistic regression models, decision trees, and neural networks, data from 500 high school students in public institutions were analyzed. The results show that advanced statistical techniques allow a more accurate prediction of academic performance, with a success rate of 87% in neural network models. These findings suggest that the integration of these tools can facilitate (...) the early identification of students at risk of low achievement and improve educational interventions. (shrink)

The identity is an arduous and complex topic that includes practically all the aspects of the life of a human being. The identity, mediated narrative, plays a role aimed at the personal direction of ours lives and sociocultural function linked to the quest for recognition of the rights of social groups to which one feels attached . Between economic globalization and pluralization of the life forms, identity is the result of a double disorientation. At the individual level, the insecurity work, (...) the flexibility of human relations, the rise in divorces or international migrations require rethinking, constantly, the circumstances on which our lives are developed. At the collective level, the new transnational agents like ONU or OTAN and local agents like nationalism, ethnic or immigrant groups forced to rethink the space of groups, collectives and communities between the global homogenization and local heterogeneity.

We defend the moral and legal right to secede in accordance with plebiscitary theory. Our paper has three main goals. First, by offering a schematic characterization of plebiscitary theory, the main arguments in its favour (and the main objections to them), we contribute to clarify the structure of this complex debate. Second, we stress the point that, if the moral right to secede is established, the resistance for its inclusion into positive law is unjustified. Finally, by addressing old and new (...) objections to plebiscitary theory, we hope to make a compelling case for a wider recognition of secessionist rights. (shrink)

This paper approaches web archiving as preservation of digital memory and as a dynamic informational environment with complex problems of harvest, use, access and preservation. It uses a qualitative and exploratory-descriptive approach, identifying web archiving initiatives and promoting a reflection on the ways of defining web information collection, geographical gaps in web archiving and problems regarding uses and rights of this information. Whereas initiatives such as Internet Archive harvest a lot of information from across the web, an imbalance of digital (...) memory exists where many countries do not possess their own web archiving initiatives, and therefore, coverage of information is unequally produced.

This paper presents a formalism that combines useful properties of both logic and probabilities. Like logic, the formalism admits qualitative sentences and provides symbolic machinery for deriving deductively closed beliefs and, like probability, it permits us to express if-then rules with different levels of firmness and to retract beliefs in response to changing observations. Rules are interpreted as order-of-magnitude approximations of conditional probabilities which impose constraints over the rankings of worlds. Inferences are supported by a unique priority ordering on rules (...) which is syntactically derived from the knowledge base. This ordering accounts for rule interactions, respects specificity considerations and facilitates the construction of coherent states of beliefs. Practical algorithms are developed and analyzed for testing consistency, computing rule ordering, and answering queries. Imprecise observations are incorporated using qualitative versions of Jeffrey's rule and Bayesian updating, with the result that coherent belief revision is embodied naturally and tractably. Finally, causal rules are interpreted as imposing Markovian conditions that further constrain world rankings to reflect the modularity of causal organizations. These constraints are shown to facilitate reasoning about causal projections, explanations, actions and change. (shrink)

Resumen: El propósito de este trabajo es mostrar cómo la propuesta de la nueva retórica de Chaïm Perelman se constituye fundamentalmente en una teoría de la racionalidad práctica en perspectiva argumentativa. Para el desarrollo de esta tesis procedemos de la siguiente manera: primero se describe el giro pragmático que lleva a Perelman a señalar los límites de la lógica formal deductivista para el campo de los valores en algunos de sus textos de juventud; a continuación se muestra la apuesta de (...) Perelman por una nueva retórica como un tipo de aplicación de la racionalidad, desarrollada en su Tratado de la argumentación y algunos textos posteriores a 1958; y finalmente se desarrolla la noción perelmaniana de lo razonable en el marco de la argumentación jurídica, para mostrar cómo, desde esta perspectiva, Perelman se vincula al debate de la segunda mitad del siglo XX conocido como la “doctrina de los casos difíciles en derecho”.: The purpose of this work is to show how Chaïm Perelman’s new rhetoric proposal fundamentally constitutes a theory of practical rationality in an argumentative perspective. To develop this thesis, we proceed as follows: first, we describe the pragmatic turn that leads Perelman to point out the limits of formal deductivist logic in the field of values, in some of his youth texts; then, Perelman’s bet on new rhetoric is presented as a kind of application of rationality, developed in his Treaty of Argumentation and in some texts written after 1958; finally, the Perelmanian notion of reason is developed in the framework of legal argumentation, to show how, from this perspective, Perelman is linked to the debate of the second half of the twentieth century known as the “doctrine of difficult cases in law”.

Scientist naturalism as pseudo religion and anti-natural theology After exposing the basic ideas of the naturalistic worldview, an attempt is made to show that naturalism is an interpretation of science that has an inescapable "mythological" dimension, in the sense that Midgley gives to this expression. This does not discredit it on principle but means that we cannot accept it uncritically by the mere fact that it appeals to the natural sciences to justify its validity. It is then argued that the (...) central commitment of naturalists is the affirmation of atheism. In fact, the most radical contemporary naturalisms can be interpreted as an attempt to make every natural theology impossible, i.e., they seek to destroy the grounds on which reason classically relies to affirm the existence of God. It is argued that naturalism does not necessarily enjoy a priori epistemological superiority over theism. (shrink)

This book introduces readers to Indian philosophy by presenting the first integral English translation of Vaiśeṣikasūtra with the earliest extant commentary of Candrānanda on the old aphorisms of Vaiśeṣika school of Indian philosophy. The book offers a comprehensive description of the fundamental categories of ontology and metaphysics, among which the category of 'particularity' plays a major role in the 'problem of individuation' of 'substance' and 'nature' in both Indian and Western metaphysics. The book should be read primarily in relation to (...) Aristotle's Categories and is structured in three parts. Part 1 contains a general introduction to Indian philosophy and the Vaiśeṣika system. Part 2 is a textual-philological discussion on the commentary itself, since its first publication in 1961 by Muni Jambūvijayaji up until the present day. Part 3 is a philosophical translation that reads Vaiśeṣika in the global context of Comparative Philosophy and makes the text accessible to all philosophy readers interested in ontology and metaphysics. A new reference work and a fundamental introduction to anyone interested in Indian and Comparative Philosophy, this book will be of interest to academics and students in the field of Classical Studies, Modern Philosophy and Asian Religions and Philosophies.

Varios autores afines al proyecto del liberalismo político han propuesto diferentes modelos de razón pública para enfrentar la situación de desacuerdo moral permanente en las sociedades liberales. En este trabajo presentamos un modelo que defiende dos argumentos. Primero, argumentamos a favor de una interpretación deflacionista de las razones que son aceptables para los ciudadanos razonables. Segundo, introducimos una nueva terminología que distingue entre lo que llamamos razones dependientes, accesibles y aceptables. Sostenemos que sólo las segundas y las terceras son medios (...) adecuados de discusión dentro de la razón pública, y las terceras son un estándar correcto de justificación de política pública.

En la ética y la filosofía política contemporáneas es común apelar a alguna for-ma de consenso hipotético para justificar contenidos normativos. En el presente artículo llamo a esta posición “contractualismo” y defiendo tres tesis al respecto. Primera, es correcta la objeción común al contractualismo de que la estipulación de un consenso hipotético en una situación ideal de deliberación no añade nada a la justificación del contenido normativo en cuestión. Segunda, esta objeción da pie a lo que llamo “el dilema contractualista”: (...) cuando hay una situación de des-acuerdo entre dos agentes sobre si un contenido normativo x es correcto, apelar a un acuerdo hipotético en condiciones ideales de deliberación como medio para justificar x, equivale a caer en petición de principio o a establecer una trivialidad. Tercera, a la luz del “dilema contractualista”, el contractualismo no debe ser en-tendido como un método de justificación normativa. (shrink)

The uncertainty concerning the genre of the Ḥorvat ʿUza ostracon 1 is problematized through the lens of linguistic anthropology. Although a denotative approach to the linguistic forms in this Hebrew ostracon is well attested, less attention has been paid to the indexical meaning of specific stylistic features and their semi- otic register implications. Several linguistic-ideological concepts are drawn upon to examine how the act of inscription and specialized linguistic forms align the discursive genre of the ostracon with prophecy. I seek (...) to determine what salient discourse forms in the ostracon index the employment of habitual utterance styles of prophecy that construct context, genre, and social identity. (shrink)

El término aventura resumiría lo que de impulso inmanentista encierra el bergsonismo. Dicha aventura, empero, se ve finalmente empañada por las más diversas consideraciones de tipo espiritualista y de modo especial por la inquietud teológica del último Bergson. Llevar a cabo esa aventura implicaría formar un "circuito" entre lo virtual y lo posible. Sería así desarticulada en la ontología bergsoniana la inquietud antes mencionada y pensado el futuro con condiciones humanistas.

El papel que ocupa la poesía en la escuela queda, generalmente, reducido a ejercicios de recitación de poemas en jornadas que conmemoran fechas señaladas. Como formadores de maestros y maestras en la Facultad de Educación de la Universidad de Lleida, en las materias relacionadas con la didáctica de la literatura, pretendemos que nuestros estudiantes amplíen su mirada sobre el género poético y lo conciban como parte de la educación literaria de calidad de sus futuros discentes. La dramatización de poemas, como (...) aquí explicamos y ejemplificamos, es un buen modo de hacerlo para lograr la educación literaria antes citada. (shrink)

En las páginas que siguen trato de acercarme a estos dos grandes pensadores para ver qué es lo que tienen que decirnos acerca del hombre y de su historia. Marx confía en el progreso histórico y cree que finalmente los hombres pasarán del reino de la necesidad al de la libertad. Vico, en cambio, nunca creyó que el progreso fuese una necesidad que tenía que producirse inevitablemente, ni mucho menos que fuese irreversible, pues la barbarie está siempre acechando y toda (...) conquista es siempre precaria.I take this paper to be an approach to these two great thinkers in order to find out what they have to say about man and his history. Marx, unlike Vico, relies heavily in the historical progress and seems to be firmly convinced that men would eventually step into the kingdom of freedom once they have abandoned that of necessity. Vico, on the other hand, never believed that progress was bound inevitably to occur, let alone that it were an unavoidable process, since barbarism is always lying in wait and all conquer appears to be meager.

En el presente trabajo hablaremos del desarrollo filosófico que Hegel hace de la ópera en su Estética. Para ello, haremos una breve explicación sobre las características de las dos versiones que hoy tenemos de esta obra hegeliana; esto tanto en su origen histórico como en las implicaciones teóricas de cada uno de estos textos. Posteriormente, localizaremos la ópera en cada una de las versiones de la Estética, para poder así exponer las particularidades y diferencias teóricas entre ambos materiales bibliográficos. Cabe (...) mencionar que profundizaremos en la ópera pensada como Gesamtkunstwerk, noción encontrada en la versión más reciente de los cursos de estética de Hegel, puesto que consideramos, además de su novedad, que es una noción del espíritu que nos conduce a nuevas precisiones en el estudio del pensamiento del filósofo de Stuttgart.

En este trabajo respondo una objeción a la tesis de que la teoría de Rawls debe atender problemas relacionados a la injusticia histórica. Esta objeción sostiene que dicha teoría está justificada en no considerar problemas de injusticia histórica debido a su supuesto carácter exclusivamente prospectivo. La objeción tiene dos presentaciones diferentes. Primero, como la idea de que hay razones internas a la propia teoría de Rawls que justifican dicho carácter exclusivamente prospectivo —tales como el problema de elección modelado en la (...) posición original y el hecho de que la justicia-como-equidad debe ser una concepción de justicia no-comprehensiva. Segundo, como la idea de que hay razones externas a la teoría de Rawls —en concreto, la supuesta existencia del así llamado problema de la no-identidad, que justifican el carácter exclusivamente prospectivo no sólo de los principios de justicia rawlsianos sino de cualquier otra concepción de justicia distributiva. Trataré de mostrar que esta objeción, tanto en su presentación interna como externa, es equivocada. (shrink)

The purpose of this paper is to expand the theoretical field of discursive injustice by identifying a specific kind of discursive injustice, namely, the kind we are subject to when we are unjustly prevented from exchanging reasons with others. Broadly speaking, discursive injustice is the kind of injustice we suffer when we are unjustly harmed as language users, most notably when we are prevented from using language in ways we are entitled to. The dominant approach to discursive injustice has focused (...) on the corruption of the illocutionary force of a speech act due to the hearer’s improper uptake. I claim that there is a genuinely distinct kind of discursive injustice, which I label as deliberative injustice, that cannot be accounted for by the dominant approach to discursive injustice. In my view, what makes deliberative injustice discursively unjust is that it amounts to denying someone a normative position that she is entitled to as a language user, which I understand in terms of being a source of reasons. Moreover, I explore two ways of trying to illuminate deliberative injustice by appealing to the social level of analysis, namely, by resorting to a structural explanation to explain how it comes about, and by asking what it signifies for the collective life of groups. In this regard, I show that the structural explanation has some explanatory limitations, and that deliberative injustice essentially constitutes a collective failure. (shrink)
