Some metaphysicians believe that metaphysical modality is explainable by the essences of objects. In §II, I spell out the definitional view of essence, and in §III, a working notion of metaphysical explanation. Then, in §IV, I consider and reject five natural ways to explain necessity by essence: in terms of the principle that essential properties can't change, in terms of the supposed obviousness of the necessity of essential truth, in terms of the logical necessity of definitions, in terms of Fine's (...) logic of essence, and in terms of the theory of real definitions. I will conclude that the present evidence favours rejecting the hypothesis that modality is explainable by essence. (shrink)

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My (...) analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science. (shrink)

This textbook presents the basics of philosophy that are necessary for the student and researcher in science in order to better understand scientific work. The approach is not historical but formative: tools for semantical analysis, ontology of science, epistemology, and scientific ethics are presented in a formal and direct way. The book has two parts: one with the general theory and a second part with application to some problems such as the interpretation of quantum mechanics, the nature of mathematics, and (...) the ontology of spacetime. The book addresses questions such as "What is meaning?", "What is truth?", "What are truth criteria in science?", "What is a theory?", "What is a model?" "What is a datum?", "What is information?", "What does it mean to understand something?", "What is space?", "What is time?", "How are these concepts articulated in science?" "What are values?" "What are the limits of science?", and many more. The philosophical views presented are "scientific" in the sense that they are informed by current science, they are relevant for scientific research, and the method adopted uses the hypothetical-deductive approach that is characteristic of science. The results and conclusions, as any scientific conclusion, are open to revision in the light of future advances. Hence, this philosophical approach opposes to dogmatic philosophy. Supported by end-of-chapter summaries and a list of special symbols used, the material will be of interest for students and researchers in both science and philosophy. The second part will appeal to physicists and mathematicians. (shrink)

Preposed negation yes/no (yn)-questions like Doesn''t Johndrink? necessarily carry the implicature that the speaker thinks Johndrinks, whereas non-preposed negation yn-questions like DoesJohn not drink? do not necessarily trigger this implicature. Furthermore,preposed negation yn-questions have a reading ``double-checking'''' pand a reading ``double-checking'''' p, as in Isn''t Jane comingtoo? and in Isn''t Jane coming either? respectively. We present otheryn-questions that raise parallel implicatures and argue that, in allthe cases, the presence of an epistemic conversational operator VERUMderives the existence and content of the (...) implicature as well as thep/ p-ambiguity.

The term “Reduced Conditional” is coined by Schwarz (1996, 1998, 2000) to designate a certain kind of ellipsis that may occur in the consequent of a Conditional in German, as illustrated in (1): (1a) is a Full Conditional (FC, henceforth) and (1b) is its Reduced Conditional (RC) counterpart.

Advocates of the self-corrective thesis argue that scientific method will refute false theories and find closer approximations to the truth in the long run. I discuss a contemporary interpretation of this thesis in terms of frequentist statistics in the context of the behavioral sciences. First, I identify experimental replications and systematic aggregation of evidence (meta-analysis) as the self-corrective mechanism. Then, I present a computer simulation study of scientific communities that implement this mechanism to argue that frequentist statistics may converge upon (...) a correct estimate or not depending on the social structure of the community that uses it. Based on this study, I argue that methodological explanations of the “replicability crisis” in psychology are limited and propose an alternative explanation in terms of biases. Finally, I conclude suggesting that scientific self-correction should be understood as an interaction effect between inference methods and social structures. (shrink)

I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...) to substantival spacetime in such a way that relationism and substantivalism are not necessarily opposed positions, but rather complementary. In an appendix I give axiomatic formulations of my ontological views. (shrink)

For mankind, death is a great mystery. Throughout history, numerous opinions about death have been issued, in search of its cause, and many ways and means to defeat it have been attempted. Recent scientific developments have not stayed back from the challenge of studying biological life and attempting technological solutions to help people reach an advanced age that is not subject to decrepitude, and perhaps even to achieve immortality. This idea is also present in the transhumanist movement that aims to (...) change human nature through technology and supports the possibility of obtaining a lifespan capable of far exceed the current one. In this text, we attempt to give a possible answer to this transhumanist challenge from an orthodox Christian point of view. (shrink)

Background: Eye movement desensitization and reprocessing [EMDR] is an innovative, evidence-based and effective psychotherapy for post-traumatic stress disorder [PTSD]. As with other psychotherapies, the effectiveness of EMDR contrasts with a limited knowledge of its underlying mechanism of action. In its relatively short life as a therapeutic option, EMDR has not been without controversy, in particular regarding the role of the bilateral stimulation as an active component of the therapy. The high prevalence of EMDR in clinical practice and the dramatic increase (...) in EMDR research in recent years, with more than 26 randomized controlled trials published to date, highlight the need for a better understanding of its mechanism of action. Methods: We conducted a thorough systematic search of studies published until October 2017, using PubMed, ScienceDirect, Web of Knowledge and Scopus databases that examined the mechanism of action of EMDR or provided conclusions within the framework of current theoretical models of EMDR functioning. Results: Seventy-five studies were selected for review and classified into three overarching models; (i) psychological models (ii) psychophysiological models and (iii) neurobiological models. The evidence available from each study was analysed and discussed. Results demonstrated a reasonable empirical support for the working memory hypothesis and for the physiological changes associated with successful EMDR therapy. Recently, more sophisticated structural and functional neuroimaging studies using high resolution structural and temporal techniques are starting to provide preliminary evidence into the neuronal correlates before, during and after EMDR therapy. Discussion: Despite the increasing number of studies that published in recent years, the research into the mechanisms underlying EDMR therapy are still in its infancy. Studies in well-defined clinical and non-clinical populations, larger sample sizes and tighter methodological control are further needed in order to establish firm conclusions. (shrink)

This paper develops a framework for TAG (Tree Adjoining Grammar) semantics that brings together ideas from different recent approaches. Then, within this framework, an analysis of scope is proposed that accounts for the different scopal properties of quantifiers, adverbs, raising verbs and attitude verbs. Finally, including situation variables in the semantics, different situation binding possibilities are derived for different types of quantificational elements.

I present a formal ontological theory where the basic building blocks of the world can be either things or events. In any case, the result is a Parmenidean worldview where change is not a global property. What we understand by change manifests as asymmetries in the pattern of the world-lines that constitute 4-dimensional existents. I maintain that such a view is in accord with current scientific knowledge.

El texto aborda uno de los temas de la violencia contemporánea, la violencia política de las mujeres. A partir de los problemas para nombrar la violencia y de los análisis de A. Cavarero sobre el «horrorismo», se centra en dos casos: la muerte de Yoyes y las mujeres bombas suicidas chechenas, mostrando las construcciones sociales y culturales de sexo/género, sus mitos y estereotipos, en cuanto constituyen una de las raíces más profundas y persistentes de la violencia. En definitiva, de lo (...) que se trata es de reflexionar y comprender la vulnerabilidad de la condición humana. (shrink)

El trabajo ofrece un análisis crítico a la noción de cuerpo propio (Leib) en M. Merleau-Ponty, como superación del dualismo cuerpo-mente. Se amplía dicha noción para integrar las experiencias del cuerpo físico (Körper) y posibilitar el diálogo entre fe-nomenología y medicina, al proponer una fenomenología del organismo doliente.

Selon des auteurs comme Byung-Chul Han, la société contemporaine est une société de la transparence, où les espaces de secret et d’intimité diminuent. Cela devait, en principe, réduire la croyance aux théories du complot, étant donné que le complot est seulement possible sous le couvert du secret. Cependant, les théories complotistes disposent encore d’un public nombreux, et d’une large diffusion sur internet et les réseaux sociaux. Cet article examine ainsi comment la spéculation sur le secret et le complot se maintient (...) malgré la prétendue transparence de la réalité sociale, ou peut-être favorisée par elle. Cette étude prend appui sur la « théorie conspiratrice de l’ignorance » telle qu’elle fut définie par Karl Popper. Après avoir passé en revue les notions de « société transparente » selon Gianni Vattimo et de « société de la transparence » selon Han, nous tenterons d’identifier les espaces qui demeurent pour le secret et le complot, dans un monde où tout est censé être exposé au regard de tous. Ceci nous conduira ensuite à nous interroger sur la pertinence actuelle de la « théorie conspiratrice de l’ignorance » poppérienne. (shrink)

A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertaks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight.

This paper describes a novel pedagogical software program that can be seen as an online companion to one of the standard textbooks of formal natural language semantics, Heim and Kratzer (1998). The Penn Lambda Calculator is a multifunctional application designed for use in standard graduate and undergraduate introductions to formal semantics: Teachers can use the application to demonstrate complex semantic derivations in the classroom and modify them interactively, and students can use it to work on problem sets provided by the (...) teacher. The program supports demonstrations and exercises in two main areas: (1) performing beta reduction in the simply typed lambda calculus; (2) application of the bottom-up algorithm for computing the compositional semantics of natural language syntax trees. The program is able to represent the full range of phenomena covered in the Heim and Kratzer textbook by function application, predicate modification, and lambda abstraction. This includes phenomena such as intersective adjectives, relative clauses and quantifier raising. In the student use case, emphasis has been placed on providing “live” feedback for incorrect answers. Heuristics are used to detect the most frequent student errors and to return specific, interactive suggestions. (shrink)

En este estudio se exploran recursos didácticos para fomentar la reflexión intercultural en el aula de idiomas. En un aula de alemán como lengua extranjera de una universidad española, con alumnas y alumnos de nivel inicial (A1.2), se integraron actividades para el desarrollo de la competencia comunicativa intercultural en una programación anterior de orientación comunicativa y con fuerte presencia de la interacción oral entre pares. Los resultados obtenidos en esta investigación cuasi-experimental informan sobre el desarrollo de la conciencia cultural de (...) las y los participantes. (shrink)

Toda la vida sólo escuchando. ¿A quién? A la autoridad en todas sus formas; las más burdas y las más sutiles. Luego, más tarde, sólo oír. Oír, no escuchar. Con órdenes estrictas a las neuronas para no almacenar la información oída. Con los músculos faciales entrenados para poner cara interesante, mientras la conciencia dormita. Luego resultó que es mucho peor hablar. Decir, decir, decir. Mover la lengua, los pulmones, las cuerdas vocales... Sentir la señal roja que se prende en el (...) cerebro y advierte:" ¡Atención! ¡Exceso de estupideces!". Hablar de la realidad del mundo que desconozco; de la realidad de los libros que desconozco, de la realidad de los seres humanos que desconozco.

I argue for a four dimensional, non-dynamical view of space-time, where becoming is not an intrinsic property of reality. This view has many features in common with the Parmenidean conception of the universe. I discuss some recent objections to this position and I offer a comparison of the Parmenidean space-time with an interpretation of Heraclitus’ thought that presents no major antagonism.

I argue that there are no physical singularities in space–time. Singular space–time models do not belong to the ontology of the world, because of a simple reason: they are concepts, defective solutions of Einstein’s field equations. I discuss the actual implication of the so-called singularity theorems. In remarking the confusion and fog that emerge from the reification of singularities I hope to contribute to a better understanding of the possibilities and limits of the theory of general relativity.

ABSTRACT Data from digital technologies are increasingly integrated in public health research. In April of 2020, we interviewed a subset of participants who completed a survey approximately one month earlier. Using the survey, we contacted and interviewed participants who had expressed their willingness or unwillingness to share digital data for use in public health. We followed a directed content analysis approach for the analysis of the interview data. Among participants who had reported being unwilling to share data, concerns about privacy, (...) confidentiality, and the purpose of the research were cited. During the interviews, 76.9% of the participants who had who had previously indicated that they were unwilling to share their data, expressed willingness to share data in order to assist with COVID-19 prevention. Our results contribute to our understanding of people’s perspectives on sharing personal data and of the way their perspectives can vary as a function of potential uses of their personal information.

The experimental interventions that provide evidence of causal relations are notably similar to those that provide evidence of constitutive relevance relations. In the first two sections, I show that this similarity creates a tension: there is an inconsistent triad between Woodward’s popular interventionist theory of causation, Craver’s mutual manipulability account of constitutive relevance in mechanisms, and a variety of arguments for the incoherence of inter-level causation. I argue for an interpretation of the views in which the tension is merely apparent. (...) I propose to explain inter-level relations without inter-level causation by appealing to the notion of fat-handed interventions, and an argument against inter-level causation which dissolves the problem.

My aim in this note is to shed light on ways of interpreting Kant’s Formula of Universal Law (FUL), by looking at relevant similarities and differences between Pauline Kleingeld and Mark Timmons. I identify both their readings as a formal interpretation of Kant’s FUL, in contrast to the substantive interpretations that favor a robust conception of rational agency as a necessary requirement for moral deliberation. I highlight the benefits that arise from Kleingled’s interpretation in showing the immediacy involved in the (...) volitional self-contradiction when universalizing a maxim. Alongside Timmons, I address a question as to whether Kleingeld’s interpretation is completely free from at least a minimal set of assumptions about practical deliberation more broadly, that seem to play a role in generating the volitational self-contradiction she is defending. I close by raising some skeptical worries about the capacity of this kind of contradiction to translate into a moral judgment triggering action. (shrink)

El propósito de este estudio es dilucidar algunos de los rasgos distintivos de la concepción del ser humano que mantiene Jürgen Habermas y sus implicaciones en la teoría de la acción comunicativa. De este modo, se trata de mostrar que la antropología habermasiana se singulariza por adoptar una perspectiva naturalista y darwinista. En la primera parte, se analiza el legado epistemológico de Darwin como un programa de investigación y se contrastan los estudios de Habermas sobre antropología biológica con las últimas (...) investigaciones en genética y paleontología. En la segunda parte, se presenta la propuesta de Habermas de afrontar un dualismo epistemológico mediante un naturalismo débil noreduccionista, como crítica de la metafísica moderna y estructurador de un nuevo realismo.

The interpretation of man which I have defended in my book, Theory of Man, agrees with the Linnaean designation of homo sapiens, which is more exact, in my opinion, than the classical one of “rational animal.” In that work I maintain that what is peculiar to man is that he is conscious of a reality outside of himself and of his own intimate being, or, in other words, that he recognizes the independent existence of the world and is an ego. (...) Both matters can be reduced to a unique primary function: the objectifying activity, which in normal, continuous, and accumulative operation belongs only to man, and from which all essentially human traits are derived. The peculiar characteristic of perception properly so called, that is, human perception, is the observation of things that are present, the recognition that a given thing exists. To perceive, then, is to attribute presence or existence to what is perceived, to admit it as an object existing by itself, certainly in different ways according to whether it is a question of external things, of the subjective entity, or of the processes and “states” inherent in it; let it be noted that when perceptive attention fastens upon the “states,” that is to say, on subjective, unintentional processes like those of coenesthesia which ordinarily are not perceived but are lived, enjoyed, or suffered, these become objectified without losing in themselves their condition of states. The capacity to objectify is the bedrock of human nature; animal conscience (if it deserves this name) must be imagined, save for rare exceptions, to be a succession of “states” to which objectifying attention is not applied because such attention can only come from an ego.
