Hablar de tradición cualitativa tiene un doble sentido, una doble vía. Primero, significa que después de múltiples polémicas, el paradigma crítico reflexivo se ha consolidado sobre la base de argumentos epistemológicos y empíricos sólidos. Segundo, que comienza un camino de anquilosamiento, aparición de recetarios que serían el propio espejo de lo criticado al positivismo. Ya existen atisbos, síntomas de ese proceso en la elaboración de trabajos de grado y/o tesis. Este posible estancamiento de las investigaciones cualitativas, en ocasiones obedece a (...) la buena intención de mantener un estándar de rigurosidad científica, rigurosidad que se confunde con el endurecimiento en la forma, el recorrido y estructuración del informe final, en oposición a la flexibilidad que toda investigación dentro de este paradigma posee de suyo. En nuestra opinión, una de sus mayores fortalezas es la posibilidad que brinda para echar mano de distintos métodos producto de la necesidad misma de la investigación, cuando esta nos exige la revisión de formas alternativas para poder descubrir y describir el fenómeno estudiado. Es el río de Heráclito, o mejor, el de Cratilo (Aristóteles, IV, p. 191): no podremos bañarnos en el mismo río “ni siquiera una vez”. (shrink)

This book brings together a number of researchers of different nationalities to reflect on religion and philosophy in ancient Greece. These scholars have been convened by the Brazilian research group Delphos and discuss, in particular, how religious and philosophical thought intertwined during this period. Among the papers collected here, several are devoted to epic and philosophical literature before Plato. The others deal, alongside this great classical philosopher, with Aristotle and Philo of Alexandria. These contributions allow us to recognise how the (...) vision of the cosmos, metaphysics and human life are intertwined in Greek thought. A journey is made from traditional Greek religion to its philosophical reinterpretations, reaching as far as the monotheistic God of Judaism made known in the Hellenic language. The nature of the cosmos, investigated scientifically, is no stranger to the Greeks' view of the divine, but neither is ethics, with all its demands. Thus, these studies provide a kaleidoscopic view of the various points of view from which nature, the human condition and divinity are approached through the eyes of ancient Greek literature.

Desde una visión holística abordamos la comprensión lectora en el aula a fin de dar respuestas puntuales y aportar soluciones. Producto de una investigación cualitativa, Investigación-Acción en el aula, damos cuenta de los diversos factores que intervienen en dicho proceso y cómo lo modifican: el clima de aula, el aprendizaje cooperativo, el aprender haciendo, aprendizaje significativo y la metacognición, los cuales hemos denominado estrategias interactivas. Estas estrategias consolidan la comprensión lectora de los participantes y, al mismo tiempo, pueden ser aplicadas (...) por los participantes en su praxis educativa en el subsistema de primaria. Asimismo, se estudian los elementos que entran en juego: el texto, el lector y el contexto, e intentamos redimensionarlos en estrecha relación con las estrategias propuestas. A partir de este análisis proponemos un holos de la comprensión lectora y, en su conjunto, la interacción de los aspectos que lo conforman constituye una holopraxis, y una solución para el aula. Concluimos que la comprensión lectora es relativa y progresiva, producto de la interacción cognitiva, afectiva y social entre textos, lectores y contextos. (shrink)

Esta obra hace referencia a una serie de reflexiones sobre diferentes enfoques de investigación, algunos clasificables como “cualitativos” otros no, y que se encuentran en pleno proceso de elaboración; otras, a falencias ya señaladas en la literatura tradicional sobre las limitaciones de la investigación positivista, aunque actualizadas a los conocimientos que ahora tenemos hoy en día. Cubre, por tanto, aspectos metodológicos (con recomendaciones para la acción) y epistemológicos, o sea, ejemplos sobre cómo se debe proceder en determinadas situaciones o como (...) pensarlos desde una perspectiva epistemológica. Ha sido pensada para roles tan diversos como el de educador, líderes sociales, directores de escuela o especialistas, y aunque nos hubiese complacido dedicar más páginas a unos y otros, la centralización en las tradiciones investigativas parecía más conveniente. Pensamos que, de esta manera, el lector puede conseguir lecturas más frescas sobre diferentes tópicos que son de aplicación múltiple para diferentes campos. (shrink)

This paper addresses the relationship between logic and phenomenology at a historical moment that precedes the big divide between analytic philosophy and phenomenology. In analysing alternative derivations of phenomenological logic, the discussion focuses on the case of two notorious neo-Kantian Mexican philosophers from the first half of the XXth century: Adalberto García de Mendoza and Francisco Larroyo. It is argued that both García de Mendoza and Larroyo made an original contribution to the discussion on the relationship between phenomenology and logic. (...) Further, this paper attempts to present a charitable portrait of both García de Mendoza and Larroyo in contrast to underrating approaches to both Mexican philosophers. In so doing, this paper adopts a historical—though not strictly biographical— perspective. While it is true that neither García de Mendoza nor Larroyo could be considered “phenomenologists” or “Husserl scholars” according to contemporary standards it is worth noticing that they engage in the discussion of phenomenological logic. Both authors had the project of developing a grounding logic for science and, as the article argues, both attempts could be even linked. Their project, however, was unfinished. The plan of this paper is as follows. The first section addresses the problem of the relationship between logic and phenomenology. The second one focuses on García de Mendoza’s contributions. The third one elaborates on Larroyo’s Logic of Sciences. And, finally, the fourth section elaborates on these Mexican philosophers’ contributions to education, making as well further observations concerning the similarities and differences between both authors.

Philosophical discussions on cognition (ranging from computational and representational approaches to the 4E fra-mework), on the one hand, and those on sound and auditory per-ception, on the other, have hitherto remained apart. In this paper, the author addresses the concept of “auditory cognition”. While committing to the conceptual analysis of the latter, the author in-troduces the discussion of modality-specif ic approaches. Since the contributions made so far in the domain of the philosophy of sound and auditory perception are prone to (...) favor computational-repre-sentational approaches —e.g., the perceptual coherence model (Méndez-Martínez, 2022)—, the exploration of 4E possibilities will lay down a series of questions aimed to encourage future developers from that viewpoint. In that sense, the author explores conceptual entailments and connections between the genealogy of theories within the philosophy of sound and auditory perception, and the hypothesis of the extended cognition (EX). (shrink)

Both Franz Brentano and Edmund Husserl addressed sound while trying to explain the inner consciousness of time and gave to it the status of a supporting example. Although their inquiries were not aimed at clarifying in detail the nature of the auditory experience or sounds themselves, they made some interesting observations that can contribute to the current philosophical discussion on sounds. On the other hand, in analytic philosophy, while inquiring the nature of sounds, their location, auditory experience or the audible (...) qualities and so on, the representatives of that trend of thought have remained silent about the depiction of sound and the auditory phenomena in the phenomenological tradition. The paper’s intention is to relate both endeavours, yet the perspective carried out is that of analytic philosophy and, thus, I pay special attention to conceptual analysis as a methodological framework. In this sense, I first explain what sound ontology is in the context of analytic philosophy and the views that it encompasses— namely, the Property View (PV), the Wave View (WV) and the Event View (EV)—. Secondly, I address the problems it entails, emphasising that of sound individuation. In a third section, I propose the possibly controversial conjunction of a “Brentano-Husserl Analysis of the Consciousness of Time” (for short “Brentano-Husserl analysis”) and outline the commonalities of both authors, without ignoring its discrepancies. My main focus is Husserl’s 1905 Vorlesungen zur Phänomenologie des Inneren Zeitbewusstseins. While addressing the Brentano-Husserl analysis, I elaborate on the problem of temporal and spatial extension (Raumlichkeit and Zeitlichkeit, respectively) of both consciousness and sound. Such comparison is a key one, since after these two developments, one can notice some theoretical movements concerning the shift of attention from sounds to the unity of consciousness, and how they mirror each other. After examining the controversial claims concerning the temporal and spatial extension of both consciousness and sound, I argue in the concluding paragraphs that while considering the accounts of sound ontology, the Brentano-Husserl analysis would probably endorse a Property View and that this could have interesting consequences for the issue of Sound Individuation. (shrink)

In the realm of the philosophy of sounds and auditory experience there is an ongoing discussion concerned with the nature of sounds. One of the contestant views within this ontology of sound is that of the Property View, which holds that sounds are properties of the sounding objects. A way of developing this view is through the idea of dispositionalism, namely, by sustaining the theory according to which sounds are dispositional properties (Pasnau 1999; Kulvicki 2008; Roberts 2017). That portrayal, however, (...) is not sufficient, as it has not inquired the metaphysical debates about dispositions beyond the conditional analysis. In this paper, I try to advance this view by including recent developments (for instance Bird 2007; Vetter 2015) in the field of dispositionalism and I analyse whether this new version can sort out known and new objections to Property View.

This paper proposes some guidelines for the undeveloped discussion of auditory epistemology. Auditory epistemology is an approach concerned with the perceptual basis for knowledge and belief, specifically around audition. The article pursues two goals. Firstly, it claims that addressing auditory perception from the viewpoint of epistemology is more fruitful than the discussion on phenomenology which has thus far dominated the debates in the literature on sound. Secondly, it elaborates a concrete proposal pertaining to the cooperation of sense-modalities. In so doing, (...) a model for “Perceptual Coherence” is suggested. The first section of the paper critically reviews the problem of perception as it is usually understood in traditional epistemology. An ensuing section outlines the model of perceptual coherence.

This paper addresses the problem of sound individuation (SI) and its connection to sound ontology (SO). It is argued that the problems of SI, such as aspatiality, extreme individuation, indexical perplexity and duration puzzles are due to SO’s uncertainties. Besides, I describe the views in SO, including the wave view (WV), the property view (PV), and the event view (EV), as Casey O’Callaghan defends it. According to O’Callaghan, EV offers clear standards to individuate sounds. However, this claim is countered by (...) the consideration that any view could also defend the standards in SO, and thus, EV does not solve any of the problems mentioned above. As a way of showing the difficulties inherited by sound’s inner ontology, the problem of its linguistic representation is also addressed. The problem of SI can be developed within the frame of the philosophy of language and, specifically, regarding the discussion about mass vs count-­sortal terms. Is the term sound a mass or a count­-sortal? It is shown that, for reasons pertaining SO, the decision regarding the case of sound as a mass or count-­sortal term remains open. SI is, thus, covered from the SO to the philosophy of language. (shrink)

The sixteenth century witnessed a major intellectual event: the birth of modernity. This book presents the School of Salamanca as the "first version of modernity", a modernity developed with a peculiarly Hispanic stamp. The Salamancans confronted the problems of a singular historical moment, in which Spain was playing a leading role in the encounter between Europe and America. The thinkers of Salamanca tackled crucial issues such as the right to property, economic ethics, freedom and slavery, the justice of war... In (...) the matrix of the Salamanca university, international law and the elements of reflection that would provide arguments for the abolition of slavery were born. This book brings together scholars from different geographical areas: several authors from Latin America, as well as from different European countries, sign their contributions. These diverse origins reflect the rich universality of the Hispanic project that had its heart in the reflections of the School of Salamanca. The diversity of topics addressed, ranging from the more practical questions of trade and the freedom of the American Indians to the subtleties of metaphysics or theology, is a good example of the richness of the issues addressed by those intellectuals who initiated modernity.

La comprensión lectora constituye un tema de estudio y preocupación en todo el sistema educativo venezolano, desde la primaria hasta el postgrado. A partir de diferentes enfoques y con diferentes métodos y estrategias se han buscado alternativas para mejorar las competencias que tienen los estudiantes. En el caso de este estudio se partió de las teorías constructivistas y de la metodología investigación acción en el aula para que los estudiantes desarrollaran la comprensión de la lectura a través de un conjunto (...) de estrategias interactivas. En cuanto a las técnicas para la recolección y análisis de la información, se utilizaron cuantitativas y cualitativas, como la observación participante, el diario de clase y la triangulación, entre otros. La investigación se efectuó en dos ciclos con estudiantes del Programa Educación, Proyecto Educación Integral, de la Universidad Nacional Experimental “Rafael María Baralt”. Los resultados evidencian mejoras sustantivas en los niveles de comprensión de la lectura del grupo, sobre todo en la lectura inferencial. Se evidencia que los aspectos como el clima del aula, aprendizaje cooperativo, aprender haciendo, aprendizaje significativo, las estrategias para la mediación de aprendizaje y los procesos metacognitivos en el proceso de aprendizaje son importantes para desarrollar la comprensión de la lectura. Asimismo, se consideran relevantes los elementos afectivos y sociales en el diseño de las estrategias. Por último, se concluye que más que consolidar la comprensión de la lectura, se consolidan los procesos cognitivos que posibilitan la comprensión. (shrink)

The objective of the research is to carry out a review of the literature about suicide risk factors in young university students. The methodology used is quantitative descriptive with a bibliometric approach, under the PRISMA method. The search was carried out in three databases: Clarivate Web of Science, MDPI and Taylor and Francis that had the variables of suicide risk factors. Inclusion criteria were used such as: study variables, years 2019 to 2022, published in Spanish and English,scientific reports research results, (...) research with clinical and non-clinical population. After the application of the Boolean operators, the total sample is (n=10360) and after screening with the PRISMA method (n=45). Results: The United States, followed by China and Bangladesh, are the countries that produce the most on the subject. The most frequent risk factors are: depression, anxiety, stress, academic commitments, lack of opportunities, low income and race. The students with the highest suicide rates are in the health area such as medicine and nursing, in addition, there is more suicide intent in women than in men. (shrink)

Are philosophy and literature allies or enemies in Jorge Luis Borges's fictions? In this paper, I argue that Borges can satisfy membership in the allies camp because his fictions provide the imaginative scenarios the allies believe are so necessary to this coalition; however, because his stories question philosophy's hold on reality, they can also seem to fall into the enemies camp by countervailing any claim philosophy has on reality and truth; although, ultimately, the manner in which Borges forges (...) an alliance between philosophy and literature will be for reasons not traditionally accepted by those in either the allies or enemies camps.

A general mathematical framework, based on countable partitions of Natural Numbers [1], is presented, that allows to provide a Semantics to propositional languages. It has the particularity of allowing both the valuations and the interpretation Sets for the connectives to discriminate complexity of the formulas. This allows different adequacy criteria to be used to assess formulas associated with the same connective, but that differ in their complexity. The presented method can be adapted potentially infinite number of connectives and truth values, (...) therefore, it can be considered a general framework to provide semantics to several of the known logic systems (eg, LC, L3 LP, FDE). The presented semantics allow to converge to different standard semantics if the separation complexity procedure is annulled. Therefore, it can be understood as a framework that allows greater precision (in complexity terms) with respect to formula satisfaction. Naturally, because of how it is built, it can be incorporated into non-deterministic semantics. The presented procedure also allows generating valuations that grant a different truth value to each formula of propositional language. As a positive side effect, our method allows a constructive proof of the equipotence between N and N^n for all Natural n. (shrink)

Some partitions of Natural Number set are built through recursive processesgenerating in this manner countable examples of countable and disjoint sets whose unionis a set also countable. This process is constructive, so the Axiom of choice is not used.We provide a PC program that generates one of these special partitions and shows howto generate infinite of them. This line of reasoning can have multiple applications in Settheory and Model theory. We proved that the number of ways to make these partitionsof (...) natural numbers is not countable, there are more of these partitions (named doublycountable) than natural numbers. For each natural number greater than 1, we show aneffective procedure that generates these partitions -/- . (shrink)

The year of the centennial of the Argentinean writer Jorge Luis Borges is probably the right time to exhume one of the links that this universal writer had with William James. In 1945, Emece, a publisher from Buenos Aires, printed a Spanish translation of William James’s book Pragmatism, with a foreword by Jorge Luis Borges.

Within ordinary ---unitary--- quantum mechanics there exist global protocols that allow to verify that no definite event ---an outcome to which a probability can be associated--- occurs. Instead, states that start in a coherent superposition over possible outcomes always remain as a superposition. We show that, when taking into account fundamental errors in measuring length and time intervals, that have been put forward as a consequence of a conjunction of quantum mechanical and general relativity arguments, there are instances in which (...) such global protocols no longer allow to distinguish whether the state is in a superposition or not. All predictions become identical as if one of the outcomes occurs, with probability determined by the state. We use this as a criteria to define events, as put forward in the Montevideo Interpretation of Quantum Mechanics. We analyze in detail the occurrence of events in the paradigmatic case of a particle in a superposition of two different locations. We argue that our approach provides a consistent single-world picture of the universe, thus allowing an economical way out of the limitations imposed by a recent theorem by Frauchiger and Renner showing that having a self-consistent single-world description of the universe is incompatible with quantum theory. In fact, the main observation of this paper may be stated as follows: If quantum mechanics is extended to include gravitational effects to a QG theory, then QG, S, and C are satisfied. (shrink)

In this paper I discuss how Borges uses his ideas on selfhood to explore the “central problem of literature” that Andre Maurois highlighted and how in the process projects to the reader his idea of reality. I argue also that the self that Borges tries to present in his work may nevertheless not be always congruent with the self he may have wanted to convey. This is because his quest is influenced by a number of factors, not least the fact (...) that the self-creation process is affected by our interplay with the external world. (shrink)

In this work we study dimensional theoretical properties of some a±ne dynamical systems. By dimensional theoretical properties we mean Hausdor® dimension and box- counting dimension of invariant sets and ergodic measures on theses sets. Especially we are interested in two problems. First we ask whether the Hausdor® and box- counting dimension of invariant sets coincide. Second we ask whether there exists an ergodic measure of full Hausdor® dimension on these invariant sets. If this is not the case we ask the (...) question, whether at least the variational principle for Haus- dor® dimension holds, which means that there is a sequence of ergodic measures such that their Hausdor® dimension approximates the Hausdor® dimension of the invariant set. It seems to be well accepted by experts that these questions are of great importance in developing a dimension theory of dynamical systems (see the book of Pesin about dimension theory of dynamical systems [PE2]). Dimensional theoretical properties of conformal dynamical systems are fairly well understood today. For example there are general theorems about conformal repellers and hyperbolic sets for conformal di®eomorphisms (see chapter 7 of [PE2]). On the other hand the existence of two di®erent rates of expansion or contraction forces problems that are not captured by a general theory this days. At this stage of de- velopment of the dimension theory of dynamical systems it seems natural to study non conformal examples. This is the ¯rst step to understand the mechanisms that determine dimensional theoretical properties of non conformal dynamical systems. A±ne dynamical systems represent simple examples of non conformal systems. They are easy to de¯ne, but studying their dimensional theoretical properties does never- theless provide challenging mathematical problems and exemplify interesting phe- nomena. We consider here a special class of self-a±ne repellers in dimension two, depending on four parameters (see 2.1.). Furthermore we study a class of attractors of piecewise a±ne maps in dimension three depending on four parameters as well. The last object of our work are projections of these maps that are known as gener- alized Baker's transformations (see 2.2.). The contents of our work is the following: In chapter two we give an overview about some main results in the area of di- mension theory of a±ne dynamical systems and de¯ne the systems we study in this work. We will explain, what is known about the dimensional theoretical properties of these systems and describe what our new results are. In chapter three we then apply symbolic dynamics to our systems. We will introduce explicit shift codings 4 and ¯nd representations of all ergodic measures for our systems using these codings. From chapter four to chapter eight we study dimensional theoretical properties, which our systems generally or generically have. In chapter four we will prove a formula for the box-counting dimension of the repellers and the attractors (see the- orem 4.1.). Then in chapter ¯ve we apply general dimensional theoretical results for ergodic measures found by Ledrappier and Young [LY] and Barreira, Schmeling and Pesin [BPS] to our systems. These results relate the dimension of ergodic measures to metric entropy and Lyapunov exponents. Using this approach we will be able to reduce questions about the dimension of ergodic measures in our context to ques- tions about certain overlapping and especially overlapping self-similar measures on the line. These overlapping self-similar measures are studied in chapter six. Our main theorem extends a result of Peres and Solomyak [PS2] concerning the absolute continuity resp. singularity of symmetric self-similar measures to asymmetric ones (see theorem 6.1.3.). In chapter seven we bring our results together. We prove that we generically (in the sense of Lebesgue measure on a part of the parameter space) have the iden- tity of box-counting and Hausdor® dimension for the repellers and the attractors. (see theorem 7.1.1. and corollary 7.1.2.). This result suggest that one can expect that the identity of box-counting dimension and Hausdor® dimension holds at least generically in some natural classes of non conformal dynamical systems. Furthermore we will see in chapter seven that there generically exists an ergodic measure of full Hausdor® dimension for the repellers. On the other hand the vari- ational principle for Hausdor® dimension is not generic for the attractors. It holds only if we assume a certain symmetry (see theorem 7.1.1.). For generalized Baker's transformations we will ¯nd a part of the parameter space where there generically is an ergodic measure of full dimension and a part where the variational principle for Hausdor® dimension does not hold (see theorem 7.1.3.). Roughly speaking the reason why the variational principle does not hold here is, that if there exists both a stable and an unstable direction one can not generically maximize the dimension in the stable and in the unstable direction at the same time. In an other setting this phenomenon was observed before by Manning and McCluskey [MM]. In chapter eight we extend some results of the last section to invariant sets that correspond to special Markov chains instead of full shifts (see theorem 8.1.1.). In the last two chapters of our work we are interested in number theoretical excep- tions to our generic results. The starting point of our considerations in section nine are results of ErdÄos [ER1] and Alexander and Yorke [AY] that establish singularity and a decrease of dimension for in¯nite convolved Bernoulli measures under special conditions. Using a generalized notion of the Garsia entropy ([GA1/2]) we are able 5 to understand the consequences of number theoretical peculiarities in broader class of overlapping measures (see theorem 9.1.1.). In chapter ten we then analyze number theoretical peculiarities in the context of our dynamical systems. We restrict our attention to a symmetric situation where we generically have the existence of a Bernoulli measure of full dimension and the identity of Hausdor® and box-counting dimension for all of our systems. In the ¯rst section of chapter ten we ¯nd parameter values such that the variational principle for Hausdor® dimension does not hold for the attractors and for the Fat Baker's transformations (see theorem 10.1.1.). These are the ¯rst known examples of dynamical systems for which the variational principle for Hausdor® dimension does not hold because of number theoretical peculiarities of parameter values. For the repellers we have been able to show that under certain number theoretical conditions there is at least no Bernoulli measure of full Hausdor® dimension; the question if the variational principle for Hausdor® dimension holds remains open in this situation. In the second section of chapter ten we will show that the identity for Hausdor® and box-counting dimension can drops because there are number theoretical pecu- liarities. In the context of Weierstrass-like functions this phenomenon was observed by Przytycki and Urbanski [PU]. Our theorem extends this result to a larger class of sets, invariant under dynamical systems (see theorem 10.2.1). At the end of this work the reader will ¯nd two appendices, a list of notations and the list of references. In appendix A we introduce the notions of dimension we use in this work and collect some general facts in dimension theory. In appendix B we state the facts about Pisot-Vijayarghavan number, we need in our analysis of number theoretical peculiarities. The list of notations contains general notations and a table with a summary of notations we use to describe the dynamical systems that we study.

Jorge Luis Borges displays an ambivalence in his writings towards the reality of time’s flow. On the one hand, he seems to accept arguments from various thinkers refuting the reality of time. “And yet, and yet…” Borges appears unable to feel completely reconciled to such a view of time. I argue that this is because a view that refutes time denies the observer too along with it. I conclude with demonstrating how Borges, by trying to identify a reconciliation (...) between a refutation of time and acknowledgment of its reality, addressed this problem. (shrink)

Chaos and Cosmos offers a new and unique interpretation of Argentine essayist and fiction writer Jorge Luis Borges as a thinker of what continental twentieth century political theory called the political. While not a political writer in the traditional sense, Borges was indeed an author whose response to the advent of totalitarianism, in particular in its Nazi form, generated the most experimental, insightful, and rigorous short fiction and non-fiction political interrogation. -/- As is well known, Borges’ writing went (...) beyond originality; it created a genre of its own, and the Borgesian style is not limited to form. This Borgesian style fundamentally relates to how his response to the advent of totalitarianism led to sharp and philosophically sophisticated interrogations-in-fiction of the political, understood in this book as related to three main distinctive dimensions: that of the question of the forms of society, that of the relationship between the imaginary and the real, and that of the relationship between the same and the other. -/- Chaos and Cosmos introduces the reader to Borges as an experimental writer, as an Argentine citizen, as a thinker of global political phenomena, and as a South American Pragmatist. The book also makes incursions in a political theorizing of its own, intertwining an interpretation of Borges’ essays and fiction pieces from the 1930s and 1940s with the central concerns of philosophers and political thinkers such as William James, Maurice Merleau-Ponty, Hannah Arendt, Claude Lefort, Michael Foucault, Richard Rorty, and Judith Butler.

According to Borges' "Three Versions of Judas": The Redeemer could feel fatigue, cold, confusion, hunger and thirst; it is reasonable to admit that he could also sin and be damned. The Redeemer, the infinite ascetic, lowered himself to a man completely, a man to the point of infamy, a man to the point of being reprehensible—all the way to the abyss. In order to save us, He could have chosen any of the destinies which together weave the uncertain web of (...) history; but He chose an infamous destiny: He was Judas. Who with a terrible lucidity premeditated his offense. ·------- Lets agree with everything EXCEPT that there was no lucidity involved. Because the Redeemer must have no regrets, no guilt (Nietzsche: "likewise sinners and bad consciences! the sting of conscience teaches one to sting"). No guilt, no regret just forgetfulness means that Judas' act of identifying Christ involved a causally deviant chain, an awkward nervous non-intentional gesture, a comic-tragic act. So it merely appeared as dishonorable but internally or psychologically was not dishonorable. (shrink)

Let (leeway) incompatibilism be the thesis that causal determinism is incompatible with the freedom to do otherwise. Several prominent authors have claimed that incompatibilism alone can capture, or at least best captures, the intuitive appeal behind Jorge Luis Borges's famous “Garden of Forking Paths” metaphor. The thought, briefly, is this: the “single path” leading up to one's present decision represents the past; the forking paths that one must decide between represent those possible futures consistent with the past and (...) the laws of nature. But if determinism is true, there is only one possible future consistent with the past and the laws and, hence, only one path to choose from. That is, if determinism is true, then we are not free to do otherwise. In this paper, I argue that this understanding of the Garden of Forking Paths faces a number of problems and ought to be rejected even by incompatibilists. I then present an alternative understanding that not only avoids these problems but still supports incompatibilism. Finally, I consider how various versions of (leeway) compatibilism fit with the Garden of Forking Paths as well as the broader question of whether metaphors, however intuitive, have any dialectical force in the debates over freedom.

This paper makes two criticisms of the book Key Concepts in Social and Cultural Anthropology, by Nigel Rapport and Joanna Overing. The second criticism is that they do not acknowledge the Argentine author Jorge Luis Borges as the conceiver of the fictional Chinese encyclopaedia. What they say raises the worry that anthropologists have not moved on much from being the handmaiden of colonialism.

In an early poem, "Year's End", Jorge Luis Borges takes the turning of the year as an occasion to consider how "something in us" endures, despite the fact that we are products of "infinite random possibilities" and "droplets in the stream of Heraclitus": It is not the emblematic detail of replacing a two with a three, nor that barren metaphor that brings together a time that dies and another coming up nor yet the rounding out of some astronomical (...) process that stuns and undermines the altiplano1 of this night, and compels us to keep listening for those twelve irreparable tollings of a bell. The true cause is a vague, pervasive apprehension of Time's enigma; a certain awe before the miracle that in spite of... (shrink)

What happens to the inner light of consciousness with the death of the individual body and brain? Reductive materialism assumes it simply fades to black.

Davies presents the reader with a sterling review of the literature--the recent history of the interest in defining "art" through the writings of Anglo-American philosophers that follow Morris Weitz' well-known 1956 essay, "The Role of Theory in Aesthetics"--and a stimulating discussion of the role of conventions in the making and appreciating of contemporary art. His emphasis on the social nature of art leads one to wonder how other recent inquiries into the multilayered contextually of the artistic enterprise might fare under (...) his perusal, for example, feminist critiques of traditional definitions of "art," challenges to the elitist makeup of the Artworld, . . . and opposition to his very choice of paradigms: in addition to Duchamp, the "hard cases" include works by John Cage, Andy Warhol, Olivier Messiaen, Jorge Luis Borges, and Gerald Hoffnung. Definitions of Art is essential reading for anyone interested in the history of aesthetics and as it informs the current dialectic on art. (shrink)

Resumen: Resulta incuestionable la importancia que el filósofo francés Gilles Deleuze otorga al cinematógrafo. Conforme a su teoría del conocimiento, si la filosofía "piensa" mediante conceptos, el cine "piensa" mediante imágenes: se trata de un medio de creación artística a la vez que de reflexión (distinta de otras formas de "escritura") acerca de los problemas de la condición humana. De hecho, afirmamos que el propio pensamiento de Deleuze guarda mucho en común con las técnicas cinematográficas, al igual que sucedería en (...) la literatura del siglo XX, por ejemplo en James Joyce (en lengua anglosajona) y Jorge Luis Borges (en lengua castellana). -/- Abstract: There is no doubt as to the importance that cinematography has for the French philosopher Gilles Deleuze. According to Deleuze's theory of knowledge, just as philosophy "reasons" through concepts, cinema "reasons" by means of images. Cinema is a means of artistic creation and at the same time reflects in a way distinct from writing on the problems of the human conditions. In fact, this essay argues that Deleuze's own thought had much in common with cinematographic techniques, a relation which occurred in the twentieth century literature of James Joyce (in the English language) and Jorge Luis Borges (in the Spanish language).

Los desencuentros de la filosofía latinoamericana con Nietzsche pueden entenderse como un síntoma de algo más que un problema de legibilidad o malentendido. En tanto pensamiento de lo uno, la filosofía latinoamericana (mayoritaria) no puede servirse del pensamiento nietzscheano: es imposi-ble construir un pensamiento del origen y la unidad desde un pensamiento de lo múltiple, como el de Nietzsche. La identidad, tan buscada por esa filosofía latinoamericana mayoritaria, es una ansiedad antigenealógica. En ese sentido, esa filosofía y su procedencia no (...) es solo eurocéntrica, como ya ha sido expuesto por otros comentaristas, sino reactiva, y esto vale para tres de sus tendencias principa-les: la filosofía normalizadora, la corriente historicista y la filosofía latinoamericana de la liberación. De ahí, de paso, la fascinación de dicho pensamiento con la idea de carencia —nunca hemos sido lo suficientemente civilizados—. Esto ha instaurado un cuerpo sufriente en América Latina, atrapado en la dialéctica de la víctima y el victimario. Se trata entonces de pensar con Nietzsche para intentar pensar sin resentimiento desde América Latina y sobre esta. ¿Nietzsche en América Latina? Sí, pero más allá de los estudios de recepción e influencia: Nietzsche como aquel estruendo capaz de infundirle una dimensión geológica al pensamiento. (shrink)

Los trabajos reunidos en este libro tienen un propósito en común. Aspiran a clarificar las principales tesis de Mainländer y su relación con otros pensadores, por ejemplo, Freud, Schopenhauer, Albert Caraco, Manlio Sgalambro, Emil Cioran, Jorge Luis Borges, entre los más destacados. Enmarcado en sus aportes valiosos, este volumen es un hito cuya vasta sapiencia y rigurosidad resulta más que favorable para la recuperación y difusión de este pensador.

According to a recent philosophical claim, “works of fiction are thought experiments” (Elgin 2007: 47), though there are relevant differences, as the role of spoilers shows—they can ruin a novel but improve the understanding we can gain through a thought experiment. In the present article I will analyze the role of spoilers and argue for a more differentiated perspective on the relation between literature and thought experiments. I will start with a short discussion of different perspectives on thought experiments and (...) argue that the mental-model view and the conception of games of make-believe are most promising for developing the present analogy. Then I will assess the similarities and differences between thought experiments and other works of fiction. I will focus on the role of spoilers and, more generally, on the foretaste context, of which they are part. This context guides readers of literary works of art to draw their attention to the literary and aesthetic quality of the text. In the case of thought experiments, on the other hand, it (i) prompts them to accept the presence of fictional elements in worldly-cognitive works and (ii) draws their attention towards cognitively relevant elements of the story. A discussion of Borges’ Pierre Menard in the last part will show that literary works of art become thought experiments if they are embedded in an appropriate foretaste context. Spoilers, thus, unveil that even works which—due to their length or plenty of detail—usually are not considered thought experiments, can perform similar cognitive functions. (shrink)

Composta attorno al 1065-1067, la lettera "Sull’onnipotenza divina" di Pier Damiani si apre con una questione posta da Desiderio, abate di Montecassino: «Sebbene Dio possa ogni cosa, non può restituire la verginità a colei che l’ha perduta. Egli ha certamente il potere di liberarla dalla pena, ma non può ridarle la corona della verginità che ha perduto». Il problema, che Pier Damiani riprendeva dalla lettera XXII di san Gerolamo, è solo in apparenza ozioso: il monaco ravennate ne fa un’autentica questione (...) filosofica, un “esperimento mentale” che solleva domande cruciali sulla natura del tempo e sul rapporto tra necessità e contingenza, leggi divine e princìpi logici, natura divina e natura umana. Il volume, a cura di Roberto Limonta, presenta la traduzione del De divina omnipotentia con note e testo latino a fronte. La prefazione di Mariateresa Fumagalli Beonio Brocchieri e il saggio introduttivo di Roberto Limonta ricostruiscono la lunga durata della questione posta da Pier Damiani, dai dibattiti teologici dei secoli medievali sino alle sue fortune nella filosofia, teologia e letteratura contemporanea.

Las relaciones entre Nietzsche y América Latina están marcadas por el desencuentro. Lo cual no implica que Nietzsche no haya sido leído en Latinoamérica; pero es diferente aludir a Nietzsche, a asumir una perspectiva nietzscheana. Por eso, en vez de usar a Nietzsche para analizar su moral, para desplazar el punto de vista, en América Latina se moraliza a Nietzsche al ponerlo al servicio de esa moral, dejándola indemne. El caso de la filosofía latinoamericana es síntoma de ese desencuentro: en (...) tanto pensamiento de lo uno, no puede servirse del pensamiento nietzscheano, ya que es imposible construir un pensamiento del origen y la unidad desde un pensamiento de lo múltiple, como el de Nietzsche. Explorar y explotar al máximo ese desencuentro, sin intentar subsanarlo, permite construir la relación entre Nietzsche y América Latina en términos nietzscheanos, lo que implicaría deshacerse de la idea misma de América Latina en tanto sujeto, para concentrarse en la disección de sus fuerzas y en la potencia y miseria de sus pasiones.

En los últimos tiempos el derecho ambiental ha ganado un puesto importante en el ámbito jurídico, hecho que refleja la preocupación que hoy se tiene por la relación del hombre con su entorno. Desde hace quince años, la Universidad Colegio Mayor de Nuestra señora del Rosario, por intermedio de su Facultad de Jurisprudencia y concretamente de la Especialización y la línea de investigación en Derecho Ambiental, ha propuesto a través de diversos proyectos avanzar en el conocimiento y análisis del ordenamiento (...) jurídico ambiental, aportando así al desarrollo, estructura y consolidación de esta rama jurídica. Bajo estos parámetros, el objetivo de esta publicación es hacer algunas reflexiones en torno a distintos temas que dentro del derecho público impactan o influyen al derecho ambiental y responder a los enormes desafíos que se presentan en la materia. Por tanto, el programa quiere contribuir desde la academia al diálogo crítico y propositivo que permita dar solución a los problemas encontrados en la aplicación del derecho ambiental. En el primer capítulo, Gloria Amparo Rodriguez describe los ordenamientos jurídicos constitucionales de Colombia, Ecuador y Bolivia a fin de analizar la forma en que cada uno de ellos consagra el derecho a un ambiente sano. A continuación, Martha Ovalle y Zelba Nidia Castro de Perez realizan un estudio de los principios de precaución y prevención, exponiendo su alcance, su fundamento desde el derecho internacional y cómo vienen siendo entendidos por nuestro ordenamiento jurídico, tanto jurisprudencial como legal. Luis Adolfo Diazgranados se ocupa de la responsabilidad de los funcionarios públicos en materia ambiental, para lo cual realiza un análisis de los deberes consagrados en la normatividad vigente. Continuando con esta temática, el profesor Jorge Agudo Gonzalez, de la Universidad Autónoma de Madrid, explora la incidencia del ambiente y los recursos naturales en los procesos contractuales, a fin de mostrar cómo estas materias se han constituido en variable fundamental en el devenir de la formación, celebración y ejecución de los contratos, desde un punto de vista crítico, los aspectos importantes del proceso sancionatorio ambiental, evidenciando las falencias y vacios del a Ley 1333 de 2009. Jairo Cabrera plantea algunas reflexiones sobre la responsabilidad, valiéndose de la doctrina internacional, sobre la problemática de la reparación por daño ambiental. Por su parte, Leonardo Güiza Suárez explica el régimen general de la responsabilidad ambiental en el ordenamiento jurídico a partir del daño de los bosques naturales y su incidencia sobre los derechos humanos. Andres Gomez Rey, desde la teoría del acto administrativo, desarrolla el análisis crítico del régimen jurídico de las aguas superficiales en el derecho ambiental. Giovani J. Herrera Carrascal realiza una disertación sobre los recursos naturales y el ambiente como elementos del espacio público que a su vez constituye en un componente del medio ambiente urbano a partir de la jurisprudencia y de las competencias respectivas. Por último, Marybell Ochoa Miranda trate el tema de los residuos hospitalarios en Colombia, exponiendo su régimen jurídico, las competencias de las autoridades ambientales, los deberes que en estos asuntos tienen los ciudadanos, proponiendo lineamientos para avanzar en la consolidación de la gestión integral de residuos hospitalarios y similares.

This paper aims at providing an epistemic defense of democracy based on John Dewey’s idea that democracies do not only find problems and provide solutions to them but they also articulate problems. According to this view, when citizens inquire about collective issues, they also partially shape them. This view contrasts with the standard account of democracy’s epistemic defense, according to which democracy’s is good at tracking and finding solutions that are independent of political will-formation and decision-making. It is also less (...) vulnerable to the criticisms that have been raised against the standard account. To show this, the paper develops a theory of expressive domination and argues that problem-articulation works best when it is inclusive and domination-free. It also shows that democratic conflict represents a fundamental element for problem-articulation. (shrink)

In this work, we discuss the failure of the principle of truth functionality in the quantum formalism. By exploiting this failure, we import the formalism of N-matrix theory and non-deterministic semantics to the foundations of quantum mechanics. This is done by describing quantum states as particular valuations associated with infinite non-deterministic truth tables. This allows us to introduce a natural interpretation of quantum states in terms of a non-deterministic semantics. We also provide a similar construction for arbitrary probabilistic theories based (...) in orthomodular lattices, allowing to study post-quantum models using logical techniques. (shrink)

En el presente trabajo, analizamos el cuento El Inmortal de Borges prestándole principal atención a las situaciones donde se entrelazan, o se tratan sin diferenciar demasiado, cuestiones vinculadas con la animalidad y la divinidad. Sostenemos que esta especie de confusión o falta de precisión al tratar cuestiones que se alejan tanto de la identidad personal y del Yo, como la inmortalidad, no es un elemento casual ni sin fundamento, sino que puede ser analizado filosóficamente adentrándonos la otredad animal. El Inmortal (...) nos manifiesta que la filosofía podría no haber sido lo suficientemente precisa al tratar la otredad, permitiendo que animalidad y divinidad, o más bien ciertas propiedades características de cada una, puedan amalgamarse dentro de los lindes de este concepto. Que el cuento de Borges haga convivir de forma tan característica la inacción con la inmortalidad hace de esta obra un objeto de reflexión obligatorio para todos los interesados en el concepto de otredad.

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

We argue that philosophers are competent to facilitate public discussion concerning restrictions on human migration across political borders. We also argue that presenting public audiences with a prima facie case for open borders offers a unique opportunity to elucidate important aspects of philosophical reasoning. Finally, we share resources and a lesson plan for those keen to examine the case for open borders with students, or to facilitate public discussion on these issues.

Dynamic Theodicy (DT) is a broad concept we bring up to designate some modern Philosophical Theology attempts to reconcile the necessary and perfect existence of God with the contingent characteristics of human life. In this paper we analyze such approaches and discuss how they have become incomprehensible because the metaphysical assumptions implicit in these explanations have lost their intrinsic relation to the natural human desire for salvation. In the first part we show Charles Hartshorne's DT-model, arising from the modal logic (...) of perfection, and the modern rational problems of this position in making infinite-necessary Being (God) and finite-contingent being (human) compatible. We note that at the heart of the contradictions in this DT account is a dialectical mode of thinking that makes it difficult to find a correct solution to this dichotomy, and to assume a human desire that could be considered related to lifelong goals. In the second part, supported by the proposal of Hans Urs von Balthasar's DT, we develop the concepts of bodily vulnerability, corporeal intentionality, and natural desire for salvation, which come from an Aristotelian-Thomistic thought. This theory is established in order to build an argument, following Alasdair MacIntyre’s ethical framework, on how to make possible the recovery of a metaphysical and anthropological desire that transcends natural aging and goes beyond death. We conclude that both human dependence and the virtues that arise naturally when human beings decide to seek the good of their transcendent condition, make it possible to recover the natural desire for salvation through divine and human love.

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

We show that determinism is false assuming a realistic interpretation of quantum mechanics and considering the sensitive dynamics of macroscopical physical systems.

In this short note we develop an unorthodox panmentalistic and libertarian dualism. Especially we skech a mental-physikal law of free will. Our aim is to to provoke the contemporary scentific common-sense.

This is a discussion of the moral psychology of monstrous evil. It suggests that deliberate monstrously evil acts committed in the name of the good by moral agents arises from a peculiar vice which blinds them to the humanity of others. It also examines an opposing virtue, generosity.

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)
