In this paper I propose a set-theoretical interpretation of the logical square of opposition, in the perspective opened by generalized quantifier theory. Generalized quantifiers allow us to account for the semantics of quantificational Noun Phrases, and of other natural language expressions, in a coherent and uniform way. I suggest that in the analysis of the meaning of Noun Phrases and Determiners the square of opposition may help representing some semantic features responsible to different logical properties of these expressions. I will (...) conclude with some consideration on scope interactions between quantifiers. (shrink)

The Generalized Quantifiers Theory, I will argue, in the second half of last Century has led to an important rapprochement, relevant both in logic and in linguistics, between logical quantification theories and the semantic analysis of quantification in natural languages. In this paper I concisely illustrate the formal aspects and the theoretical implications of this rapprochement.

In this article I present the conception of syntax emerging from the “dynamic approach” to syntax and semantics, developed in the last few decades, moving from the critic to the static theories of language, either those developed in the Chomskian framework or those based on Montague’s grammar. I will suggest that this view can be fruitfully compared with Saussure’s position on syntax.

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

The Homeostatic Property Cluster (HPC) account of natural kinds has become popular since it was proposed by Richard Boyd in the late 1980s. Although it is often taken as a defining natural kinds as such, it is easy enough to see that something's being a natural kind is neither necessary nor sufficient for its being an HPC. This paper argues that it is better not to understand HPCs as defining what it is to be a natural kind but instead as (...) providing the ontological realization of (some) natural kinds. (shrink)

“Love hurts”—as the saying goes—and a certain amount of pain and difficulty in intimate relationships is unavoidable. Sometimes it may even be beneficial, since adversity can lead to personal growth, self-discovery, and a range of other components of a life well-lived. But other times, love can be downright dangerous. It may bind a spouse to her domestic abuser, draw an unscrupulous adult toward sexual involvement with a child, put someone under the insidious spell of a cult leader, and even inspire (...) jealousy-fueled homicide. How might these perilous devotions be diminished? The ancients thought that treatments such as phlebotomy, exercise, or bloodletting could “cure” an individual of love. But modern neuroscience and emerging developments in psychopharmacology open up a range of possible interventions that might actually work. These developments raise profound moral questions about the potential uses—and misuses—of such anti-love biotechnology. In this article, we describe a number of prospective love-diminishing interventions, and offer a preliminary ethical framework for dealing with them responsibly should they arise. (shrink)

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and co-citizens. (...) In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.

Given the fact that many people use Wikipedia, we should ask: Can we trust it? The empirical evidence suggests that Wikipedia articles are sometimes quite good but that they vary a great deal. As such, it is wrong to ask for a monolithic verdict on Wikipedia. Interacting with Wikipedia involves assessing where it is likely to be reliable and where not. I identify five strategies that we use to assess claims from other sources and argue that, to a greater of (...) lesser degree, Wikipedia frustrates all of them. Interacting responsibly with something like Wikipedia requires new epistemic methods and strategies. (shrink)

Systems of logico-probabilistic (LP) reasoning characterize inference from conditional assertions interpreted as expressing high conditional probabilities. In the present article, we investigate four prominent LP systems (namely, systems O, P, Z, and QC) by means of computer simulations. The results reported here extend our previous work in this area, and evaluate the four systems in terms of the expected utility of the dispositions to act that derive from the conclusions that the systems license. In addition to conforming to the dominant (...) paradigm for assessing the rationality of actions and decisions, our present evaluation complements our previous work, since our previous evaluation may have been too severe in its assessment of inferences to false and uninformative conclusions. In the end, our new results provide additional support for the conclusion that (of the four systems considered) inference by system Z offers the best balance of error avoidance and inferential power. Our new results also suggest that improved performance could be achieved by a modest strengthening of system Z. (shrink)

In a recent paper, Berger and Nanay consider, and reject, three ways of addressing the phenomenon of unconscious perception within a naïve realist framework. Since these three approaches seem to exhaust the options open to naïve realists, and since there is said to be excellent evidence that perception of the same fundamental kind can occur, both consciously and unconsciously, this is seen to present a problem for the view. We take this opportunity to show that all three approaches considered remain (...) perfectly plausible ways of addressing unconscious perception within a naïve realist framework. So far from undermining the credibility of naïve realism, Berger and Nanay simply draw our attention to an important question to be considered by naïve realists in future work. Namely, which of the approaches considered is most likely to provide an accurate account of unconscious perception in each of its purported incarnations? (shrink)

Many of us read Peter Singer ’ s work on our obligations to those in desperate need with our students. Famously, Singer argues that we have a moral obligation to give a significant portion of our assets to famine relief. If my own experience is not atypical, it is quite common for students, upon grasping the implications of Singer ’ s argument, to ask whether Singer gives to famine relief. In response it might be tempting to remind students of the (...) ad hominem fallacy of attacking the person advancing an argument rather than the argument itself. In this paper I argue that the “ ad hominem reply ” to students ’ request for information about Singer is misguided. First I show that biographical facts about the person advancing an argument can constitute indirect evidence for the soundness / unsoundness of the argument. Second, I argue that such facts are relevant because they may reveal that one can discard the argument without thereby incurring moral responsibility for failing to act on its conclusion even if the argument is sound.

It has been claimed that naïve realism predicts phenomenological similarities where there are none and, thereby, mischaracterises the phenomenal character of perceptual experience. If true, this undercuts a key motivation for the view. Here, we defend naïve realism against this charge, proposing that such arguments fail (three times over). In so doing, we highlight a more general problem with critiques of naïve realism that target the purported phenomenological predictions of the view. The problem is: naïve realism, broadly construed, doesn’t make (...) phenomenological predictions of the required sort. So, as a result, opponents must resign themselves to attacking specific incarnations of naïve realism, or approach matters quite differently. (shrink)

When moral philosophers study ignorance, their efforts are almost exclusively confined to its exculpatory and blameworthy aspects. Unfortunately, though, this trend overlooks that certain kinds of propositional ignorance, namely of the personal costs and benefits of altruistic actions, can indirectly incentivize those actions. Humans require cooperation from others to survive, and that can be facilitated by a good reputation. One avenue to a good reputation is helping others, sticking to moral principles, and so forth, without calculating the personal costs of (...) doing so, e.g., saving someone from a burning building without calculating how personally costly or beneficial it would be. These actions are indirect moral benefits (partly) resulting from that kind of propositional ignorance. (shrink)

Este artículo examina la dimensión política del concepto de mesianismo. Se sostiene que el recurso a este concepto en ciertos filósofos contemporáneos, sobre todo Agamben, es deudor de las tesis de Schmitt, Benjamin y Taubes sobre el pensamiento paulino. Desde estas premisas, se examina la relevancia filosófico-política del mesianismo a partir de su cuestionamiento de todo nomos, justificando su carácter impolítico. El mesianismo impolítico es la antítesis de la teología política.

If you’ve got millions of dollars to donate, don’t donate them to academic philosophy. Producing philosophical articles and books faces diminishing returns and diverts money and attention from more important causes. Many philosophy books and articles contradict each other; at best, only some can be correct. Philosophy classes are poor at instilling critical thinking skills. Resources that would be spent on philosophy would be better spent elsewhere.

Digitalisation is attracting much scholarly attention at present. However, scholars often take its benefits for granted, overlooking the essential question: “Does digital technology make us better?” This paper aims to help fill this gap by examining digitalisation as a form of government (digitocracy) and the way it shapes a new kind of man: _animal digitalis_. I argue that the digitalised man is animal-like rather than machine-like. This man does not use efficient and cold machine-like language, but is rather emotionalised through (...) digital technology. If those who are ruled acted like machines, data would not be produced on a mass scale, and machine learning would stop learning. Digital man has animal features and is ruled by his brain’s reward system. We need to abandon this new form of government and the resulting man. To overcome digitalisation, we need a humanism that recovers the proper place of man over animals and artefacts, but maintains respect for the value of nature. (shrink)

My topic is two-fold: a reductive account of expertise as an epistemic phenomenon, and applying the reductive account to the question of whether or not philosophers enjoy expertise. I conclude, on the basis of the reductive account, that even though philosophers enjoy something akin to second-order expertise (i.e. they are often experts on the positions of other philosophers, current trends in the philosophical literature, the history of philosophy, conceptual analysis and so on), they nevertheless lack first-order philosophical expertise (i.e. expertise (...) on philosophical positions themselves such as the nature of mind, causality, normativity and so forth). Throughout the paper, I respond to potential objections. (shrink)

It presents the basics of the “Relativistic theory of gravitation”, with the inclusion of original texts, from various papers, published between 1987 and 2009, by theirs authors: S. S Gershtein, A. A. Logunov, Yu. M. Loskutov and M. A. Mestvirishvili, additionally, together with the introductions, summaries and conclusions of the author of this paper. The “Relativistic theory of gravitation” is a gauge theory, compatible with the theories of quantum physics of the electromagnetic, weak and strong forces, which defines gravity as (...) the fourth force existing in nature, as a static field equipped with the transmitter particles of the virtual gravitons of spins 2 and 0, within the spirit of Galilei's principle of relativity, in his generalization of Poincaré's Special Relativity that allowed the authors to universalize that the physical laws of nature are complied with regardless of the frames of reference where they apply, integrated into the Grossmann-Einstein Entwurf theory, in its further development, by those authors, therefore, this theory preserves the conservation laws of energy-impulse and angular impulse of the gravitational field jointly to the other material fields existing in nature, in the Riemann's effective spacetime, through its identity with Minkowski's pseudo Euclidean spacetime.

This is a book review of Becoming Bamboo....

Based on the Russian school of Logunov and others, with the contribution of Tom van Flandern, and his previous works on space-time, gravitational waves and speed of the gravity, the author discusses the theory of the time-space fluid that results from the supposed gravitational waves that would have detected LIGO, and reaffirms the space-time as a structural geometric property of the dynamic matter (radiation, matter and quantum vacuum), now with the strong argument that without escape, in an unnatural way, the (...) physicists and philosophers of science confer the conception of the author to that ridiculous material-space-time, while depriving Matter, of the intrinsic space-time. In addition, he warns about the conceptual contradiction existing between NASA and Caltech over gravitational waves, being absurd the concept of Caltech, operator of LIGO, since gravitational waves would propagate in five non-detectable dimensions. NASA valiant and validly recognizes that they would be waves of space; therefore, there are no space-time waves that correspond to gravitational waves that, according to the great current of relativistic physicists, would exist. Finally, the author reaffirms that the quadrupole waves detected by LIGO are waves of the quantum vacuum. (shrink)

Are strangers sincere in their moral praise and criticism? Here we apply signaling theory to argue ceteris paribus moral criticism is more likely sincere than praise; the former tends to be a higher-fidelity signal (in Western societies). To offer an example: emotions are often self-validating as a signal because they're hard to fake. This epistemic insight matters: moral praise and criticism influence moral reputations, and affect whether others will cooperate with us. Though much of this applies to generic praise and (...) criticism too, moral philosophers should value sincere moral praise and moral criticism for several reasons: it (i) offers insight into how others actually view us as moral agents; (ii) offers feedback to help us improve our moral characters; and (iii) encourages some behaviors, and discourages others. And so as moral agents, we should care whether moral praise and moral criticism is sincere. (shrink)

Astrobiocentrism is a vision that places us in a scenario of confirmation of life in the universe, either as a second genesis or as an expansion of humanity in space. It manages to raise consistent arguments in relation to questions such as what would happen to knowledge if life were confirmed in the universe, how would this change the way we understand our place in the cosmos? Astrobiocentrism raises a series of reflections in the context of confirmed discovery, and it (...) develops concepts that work directly with what would happen after irrefutable evidence has been obtained that we are not alone in space. Unlike biocentrism or ecocentrism, the astrobiocentric view is not limited to the Earth-centric perspective, and for it incorporates a multi-, inter- and transdisciplinary understanding. Therefore, the aim of this paper is to make a reflection on the astrobiocentric issues related to the challenges and problems of the discovery of life in the universe and the expansion of mankind into space. Here we explore some aspects of the transition from biogeocentrism to astrobiocentrism, astrobiosemiotics, homo mensura, moral community, planetary sustainability and astrotheology. (shrink)

In this paper, I argue the practice of procreation is immoral regardless of the consequences of human presence such as climate change and overpopulation; the lack of consent, interests and moral desert on the part of nonexistent individuals means someone could potentially suffer in the absence of moral justification. Procreation is only morally justified if there is some method for acquiring informed consent from a non-existent person; but that is impossible; therefore, procreation is immoral.

This book is an introduction to first-order modal logic. It starts with classical propositional logic and ends with first-order modal logic. The text introduces the basic theory of sets, graphs and a chapter on argumentation from contemporary pragmatics.

Phylogeography, a relatively new subdicipline of evolutionary biology that attempts to unify the fields of phylogenetics and population biology in an explicit geographical context, has hosted in recent years a highly polarized debate related to the purported benefits and limitations that qualitative versus quantitative methods might contribute or impose on inferential processes in evolutionary biology. Here we present a friendly, non-technical introduction to the conflicting methods underlying the controversy, and exemplify it with a balanced selection of quotes from the primary (...) biological literature, to invite the philosophy of biology community to pay attention to the elements that have played a primary role in its presumed resolution. We also present the basic features of our own metascientific take on the debate, and point out—as a preliminary step in preparation for upcoming, more detailed treatments—the importance that appeals to authority in fields external to phylogeography per se have played in the current status of this highly visible evolutionary biology dispute.

In recent years, there has been a concerted attack on many of the precepts of Western civilization relating to the concept of God, truth, Christianity, morality, sex, the family, and even modern science, especially biology. The concern of this volume is to explore these and other attacks through the tools of philosophy, theology, science, and intuition. It seeks to bring clarity to the ongoing struggle of Western civilization to preserve its values and traditions. -/- The West is crumbling at an (...) accelerated rate. The unfolding erasure of history, objective morality, and truth has paved the way for our current predicament. We are now standing at the precipice of the future of human civilization. The attacks on the human person are unrelenting, malicious, multifaceted, and wide-ranging in their scope and breadth, from the time prior to birth until the moment of death. If you are granted the “right” to live, then you must be prepared for unending assaults on your, mind, body, and soul. Nevertheless, the spirit of man and the greatness of God are infinitely greater than any of these assaults. It is by making sense of nonsense that humanity will be able to navigate out of the West’s current quagmire. (shrink)

This paper argues that many of the conceptual controversies in evolutionary biology are due to the use of different operational definitions. Since the set of operations is not consistent, then there are many ways to understand, in practice, how concepts should be investigated. In this paper we introduce a formal analysis to study the scope of operationalism and we conclude that the controversial concepts are in fact umbrella variables, that is, a single term can be referring to different processes, phenomena (...) or entities linked by a large ontological commitment driving operationalism. If this is correct, then many of the controversies in evolutionary biology are due, in part, to the operationalization of the objects of study. (shrink)

Although there is increasing recognition that theory and practice in science are often inseparably intertwined, discussions of scientific controversies often continue to focus on theory, and not practice or methodologies. As a contribution to constructing a framework towards understanding controversies linked to scientific practices, we introduce the notion of borrowed epistemic credibility, to describe the situation in which scientists exploit fallacious similarities between accepted tenets in other fields to garner support for a given position in their own field. Our proposal (...) is based on the analysis of a recent controversy in phylogeography, a biological subdiscipline concerned with the study of the historical causes of variation in genetic diversity within species in concrete biogeographical locations. Through a review of the arguments that support the two conflicting phylogeographic schools, we show that ‘theory’ plays essentially no role as a foundation of the controversy, whereas both sides borrow epistemic credibility from sources such as formal logic, similarity of results to those in other scientific areas, the authority of prominent scientists, or the presumed superiority of quantitative vs. verbal reasoning. Our case study underscores the indivisibility of theory and practice and provide a means to re-examine important philosophical issues such as the meaning of inference, rationality, justification, and objectivity in scientific practice.

En el marco de los estándares profesionalizantes de la academia, con sus “rankings” y productividad científica, las humanidades subsisten.

Filósofos como Marcuse han subrayado las propiedades liberadoras del quehacer artístico. Pero si hemos de pensar el arte como el Gran Rechazo, es necesario mostrar qué rechaza el arte y con qué busca sustituirlo. Respecto a estas preguntas, existen dos respuestas antagónicas. Mientras una busca en la experiencia artística rechazar lo dado en nombre de una verdad intemporal, la otra también reniega de lo dado, pero admite el carácter provisorio de toda verdad. Aunque en apariencia sutil, esta distinción es sustancial. (...) A partir de una lectura de Platón, muestro por qué en la primera posición no hay cabida para lo humano, y por qué de ella se desprenden implicaciones totalitarias. Para caracterizar a la segunda posición, me sirvo de la concepción estética de Octavio Paz y de la propuesta escultórica de Alexander Calder. Ambas propuestas permiten conciliar la insatisfacción que palpita en el arte con la alteridad que caracteriza a lo humano. (shrink)

Some philosophers hold that stifling free expression stifles intellectual life. Others reply that freedom of expression can harm members of marginalized groups by alienating them from social life or worse. Yet we should still favour freedom of expression, especially where marginalized groups are concerned. It's better to know who has repugnant beliefs as it allows marginalized groups to identify threats: free expression qua self-defence.

In this paper we present a new framework of idealization in biology. We characterize idealizations as a network of counterfactual and hypothetical conditionals that can exhibit different “degrees of contingency”. We use this idea to say that, in departing more or less from the actual world, idealizations can serve numerous epistemic, methodological or heuristic purposes within scientific research. We defend that, in part, this structure explains why idealizations, despite being deformations of reality, are so successful in scientific practice. For illustrative (...) purposes, we provide an example from population genetics, the Wright-Fisher Model. (shrink)

This is a letter from an amateur philosopher to Alex Byrne expressing perplexity on reading Byrne's chapter in The Oxford Handbook of the Philosophy of Mind, "Sensory Qualities, Sensible Qualities, Sensational Qualities" (2009).

It is described as a realization that occurred historically and may occur to individuals, supplanting default naive realism. Byrne's readings of various philosophers' accounts of sensory qualities are then contrasted with (...) an interpretation consistent with the adduced theory of indirect perception. The difficulty of imagining the view from the opposite side of the direct/indirect perception divide is remarked upon. (shrink)

Faulkner a bâti une partie de sa renommée sur la violence parfois controversée de ses récits. Mais l’acte criminel retient moins son attention que son contexte et sa signification morale. L’objet premier de la littérature, selon Faulkner, ce sont les conflits de l’homme, ou du cœur humain, avec eux-mêmes. Le propos de cet article est de mettre en évidence la façon dont Faulkner subvertit le modèle du roman noir, et substitue à l’enjeu traditionnel des histoires policières, celui des faits et (...) de l’identité du coupable, un problème moral. Il donne quelques indications sur la structure générale des rapports crime-culpabilité dans l’œuvre de Faulkner, avant de montrer comment cette thématique se décline dans ses « histoires de crime » au sens propre, c’est-à-dire dans L’Intrus (Intruder in the dust, 1948) et Le Gambit du cavalier, et irrigue la reconstitution faulknérienne de la société du Sud et de l’histoire des États-Unis.

Philosophers have rightly condemned lookism—that is, discrimination in favor of attractive people or against unattractive people—in education, the justice system, the workplace and elsewhere. Surprisingly, however, the almost universal preference for attractive romantic and sexual partners has rarely received serious ethical scrutiny. On its face, it’s unclear whether this is a form of discrimination we should reject or tolerate. I consider arguments for both views. On the one hand, a strong case can be made that preferring attractive partners is bad. (...) The idea is that choosing partners based on looks seems essentially similar to other objectionable forms of discrimination. (In particular, the preference for attractive partners is arguably both unfair and harmful to a significant degree.) One can try to resist this conclusion in several ways. I consider three possible replies. The first has to do with the possibility of controlling our partner preferences. The second pertains to attractiveness and “good genes”. The last attempts to link certain aspects of attractiveness to a prospective partner’s personality and values. I argue that the first two replies fail conclusively, while the third only amounts to a limited defense of a particular kind of attractiveness preference. So the idea that we should often avoid preferring attractive partners is compelling. (shrink)

Einstein structured the theoretical frame of his work on gravity under the Special Relativity and Minkowski´s spacetime using three guide principles: The strong principle of equivalence establishes that acceleration and gravity are equivalents. Mach´s principle explains the inertia of the bodies and particles as completely determined by the total mass existent in the universe. And, general covariance searches to extend the principle of relativity from inertial motion to accelerated motion. Mach´s principle was abandoned quickly, general covariance resulted mathematical property of (...) the tensors and principle of equivalence inconsistent and it can only apply to punctual gravity, no to extended gravity. Also, the basic principle of Special Relativity, i.e., the constancy of the speed of the electromagnetic wave in the vacuum was abandoned, static Minkowski´s spacetime was replaced to dynamic Lorentz´s manifold and the main conceptual fundament of the theory, i.e. spacetime is not known what is. Of other hand, gravity never was conceptually defined; neither answers what is the law of gravity in general. However, the predictions arise of Einstein equations are rigorously exacts. Thus, the conclusion is that on gravity, it has only the equations. In this work it shows that principle of equivalence applies really to punctual and extended gravity, gravity is defined as effect of change of coordinates although in the case of the extended gravity with change of geometry from Minkowski´s spacetime to Lorentz´s manifold; and the gravitational motion is the geodesic motion that well it can declare as the general law of gravity.

Students sometimes profess moral relativism or skepticism with retorts like ‘how can we know?’ or ‘it’s all relative!’ Here I defend a pedagogical method to defuse moral relativism and moral skepticism using phenomenal conservatism: if it seems to S that p, S has defeasible justification to believe that p; e.g., moral seemings, like perceptual ones, are defeasibly justified. The purpose of defusing moral skepticism and relativism is to prevent these metaethical views from acting as stumbling blocks to insightful ethical inquiry (...) in the classroom. This approach puts the burden of proof on the relativist or skeptic (to justify their view, contrary to appearances), and makes their views costlier: if we reject moral seemings as a kind, we must reject other less objectionable seemings too (e.g. intellectual seemings). Finally, this approach improves learning outcomes by ‘hooking onto’ student familiarity with seemings, e.g. seeing is (defeasibly justified) believing. (shrink)

In support of Descartes’ epistemology, Lex Newman advances the ‘Non-atheistic-knowledge- thesis’, i.e., indefeasible knowledge cannot be gained unless the existence of God is proved. Here I expound the ‘non-atheistic-thesis-of-Cartesian-metaphysics’, which, unlike Newman’s, refers to how four Cartesian metaphysical conclusions require the existence of God. To test whether such conclusions need divine existence, we may ask what would happen if God did not play any decisive role in the Meditations. As I argue, four unpalatable consequences would follow for Cartesian metaphysics, which (...) would ruin Descartes’ plan to refute the skeptic and the atheist alike. (shrink)

The article is divided into five sections and a conclusion. While the first section is introductory, the second looks at the problem (...) of God and knowledge certainty. Elucidating how reality is gradual according to Descartes, in the third section I address the distinction between objective, formal and eminent reality. In turn, in the fourth section, I argue that if the objective reality of God exists, that is, an idea of perfection, the imperfect evil demon could have never caused it. The last section examines the reverse argument of the fourth section, viz, whether God could have caused the existence of evil and imperfection. (shrink)

El nihilismo y el eterno retorno son conceptos centrales en el intento nietzscheano por comprender el surgimiento y la crisis de los valores, desde el advenimiento de la metafísica y la moral cristiana. Sin embargo, la valoración de estos conceptos dista de ser unívoca en la obra del filósofo alemán, ya que su sola enunciación no es suficiente para alcanzar una de las metas máximas de su pensamiento: la transvaloración. El presente artículo tiene por objetivo examinar los sentidos en los (...) que se habla de nihilismo en algunos pasajes de la obra de Nietzsche y la necesidad conceptual de llegar al pensamiento del eterno retorno como condición necesaria para efectuar la transvaloración; en este sentido, se sustentará la tesis de que el eterno retorno implica tanto la perfección como la superación del nihilismo, en la medida en que logra apartar de sí el resentimiento. Para ello, se mostrará el camino recorrido por el autor para superar la ambivalencia de la debilidad y la fuerza que acompaña el desarrollo de estos conceptos, en parte de la Ciencia Jovial y el tercer libro de Así habló Zaratustra.

En este ensayo el autor supera la contradicción teórica existente entre la Relatividad General que define el campo gravitacional como un aspecto geométrico del espaciotiempo, bien como potencial o curvatura, y la Gravedad Cuántica que lo define como una fuerza de interacción fundamental, con el cambio de la concepción del espaciotiempo de propiedad geométrica estructural del campo gravitacional, a la concepción del espaciotiempo propiedad geométrica estructural de la materia en movimiento. El espaciotiempo no es continente de la materia (Substancialismo) sino (...) que por el contrario está contenido en la materia en cuanto constituye la estructura geométrica que le da su forma y permite sus cambios, a la cual como espacio le confiere su capacidad de contener y como tiempo su capacidad de devenir. Tampoco, el espaciotiempo es la categoría de las relaciones geométricas de los cuerpos materiales y sus eventos (Relacionismo), puesto que, no es una propiedad relacional de la materia sino la propiedad estructural espacio-temporal geométrica de la materia, a la cual la dota con sus capacidades de auto contenerse y transformarse. La teoría del autor sobre el espaciotiempo es la de la materia intrínsecamente dinámica, dotada estructuralmente de las cuatro dimensiones de espaciotiempo, autocontenida espacialmente y auto deviniendo temporalmente, puesto, que la materia en su capacidad de contener dinámicamente ésta ensimisma contenida y transformándose. La partícula-onda, de la materia y del campo, no existe en el espaciotiempo, sino que éste es la propiedad geométrica intrínseca estructural de la partícula-onda, por lo tanto, adherida a su propia naturaleza interna, como su propiedad geométrica dimensional intrínseca, que con fuerza de ley se manifiesta en sus mediciones cuantitativas, bien cuando es tomada la partícula-onda en sí o en relación con otras. Así, sólo son posibles las teorías sobre la gravedad provenientes de la Gravedad Cuántica, aunque, deben reformularse renunciando a integrarlas con la visión geométrica derivada de las ecuaciones de la llamada “General Relatividad”.
