Este artículo presenta la cuestión de si las creencias religiosas son o no razonables, es decir, si tienen o no una evidencia razonable que las sustente. El interés no es comprobar la existencia de Dios, sino simplemente saber si el lenguaje religioso como tal tiene o no sentido. Para esto, primero veremos la concepción de la creencia en general. A continuación, trataremos las creencias religiosas bajo dos puntos de vistas totalmente opuestos: por un lado, se expondrá la posición de autores (...) que dicen que las creencias religiosas sí tienen una evidencia razonable que las sustenta y, por otro, nos encontraremos con autores que afirman que dichas creencias no pueden ser justificadas racionalmente porque lo espiritual refiere el ámbito de lo indecible, en el cual no es factible afirmar que los enunciados religiosos son apropiados a ser verdaderos o falsos.

How do people understand the concepts of mental health and disorder? The objective of this paper is to examine the impact of several factors on people’s judgments about whether a condition constitutes a mental disorder or a healthy state. Specifically, this study examines the impact of the source of the condition, its outcome, individual valuation (i.e., the value the individual attaches to the condition), and group valuation (i.e., the value the relevant group attaches to the condition). While we find that (...) people’s health and disorder judgments are driven by perceived dysfunction, we also find that health and disorder judgments are impacted differently by these factors. Health judgements are impacted by outcome and individual valuation, and disorder judgments are impacted by condition source. These results suggest that the folk concept of mental health is positive (i.e., mental health is more than the absence of mental disorder) and normativist (i.e., value judgments play a significant role in determining whether a condition counts as healthy), while the concept of mental disorder aligns with a naturalist perspective, at least to the extent that dysfunction plays an important role in categorizing a condition as a disorder. However, our finding that people’s dysfunction judgments are influenced by individual valuation and outcomes poses a strong challenge to naturalist accounts. To provide access to our supplementary data, an appendix has been included. (shrink)

This article inquires whether or not religious beliefs are rational, that is to say, whether or not they can be rationally sustained. The point of the article is not to prove the existence of God, but rather simply to show whether or not religious language has real meaning. To do this, we shall examine the concept of belief in general. Then we shall look at religious beliefs in particular from two opposing points of view: on the one hand, from the (...) position of authors who claim that religious beliefs can in fact be sustained by rational evidence, and on the other hand, from the perspective of other authors who affirm that these beliefs cannot be rationally justified, because spiritual discourse refers to the ineffable, which deprives it of the means to verify or deny its propositions.

In order to understand the rise of runaway solutions in the radiation reaction problem a mechanical model is used. An alternative demonstration of Daboul’s theorem, through Hurwitz’s criterion, is given. The origin of runaway solutions in electrodynamics is discussed. They arise when the particle has a negative mechanical mass or when approximations are used in the equation of motion. In the 1-dimensional mechanical model an exact and linear equation of motion for the particle is obtained, the corresponding exact solution is (...) again runaway when the mechanical mass is negative. The exact solution is not runaway when the mechanical mass is positive. However, the use of approximations leads to an equation of motion which has runaway solutions. It is exhibited that the use of approximations in the 3-dimensional mechanical model is completely necessary because the general equation of motion for the particle is non-linear. The analysis of this case proceeds in a very similar way to the one carried out in electrodynamics. This means that the number of dimensions also plays an important role in the analysis. (shrink)

Proponents of manipulation arguments against compatibilism hold that manipulation scope (how many agents are manipulated) and manipulation type (whether the manipulator intends that an agent perform a particular action) do not impact judgments about free will and moral responsibility. Many opponents of manipulation arguments agree that manipulation scope has no impact but hold that manipulation type does. Recent work by Latham and Tierney (2022, 2023) found that people's judgments were sensitive to manipulation scope: people judged that an agent was less (...) free and responsible when a manipulation was existential (impacting at least one but not all agents) than when the manipulation was universal (impacting every agent). This study examines people's judgements about existential and universal manipulation cases that involve both intentional and non‐intentional outcomes. We found that manipulation scope also affects people's free will and responsibility judgments in manipulation cases involving both intentional and non‐intentional outcomes. Interestingly, we also found that manipulation type influences the effect that manipulation scope has on people's free will judgments but not their moral responsibility judgments, which indicates that people's free will and responsibility judgments can come apart. This puts pressure on the prevalent assumption that judgments about free will and moral responsibility are conceptually bound together. (shrink)

This paper describes a case study of a program called WATCH: Workshop for Actively Thinking Computationally and Historically. The focus of the program and this paper was on using mobile application development to promote historical thinking using a plantation site visit as the focus of inquiry. WATCH was delivered during an academic enrichment youth program at a major research university in the Southeast and served a total of 30 African American and Latino high school students from low socio-economic backgrounds. Through (...) the theoretical framework of historical thinking, this case study provides descriptions of the class sessions, students’ perceptions of and interests in history and students level of historical thinking through their apps. We make suggestions about how the instructional activities could be adapted for classrooms, discuss the tensions of using technology and inquiry pedagogy to support and promote historical learning, and review the program's impact on students’ agency as learners and critical consumers and producers of historical accounts.

Debates about the genuine disease status of controversial diseases rely on intuitions about a range of factors. Adopting tools from experimental philosophy, this paper explores some of the factors that influence judgments about whether low sexual desire should be considered a disease and whether it should be medically treated. Drawing in part on some assumptions underpinning a divide in the literature between viewing low sexual desire as a genuine disease and seeing it as improperly medicalized, we investigate whether health and (...) disease judgments are affected by factors such as an individual’s gender, the cause of the low desire, whether the desire is high or low, and both personal and societal valuations of the condition. Our main findings indicate that (a) the cause of a condition influences whether it is judged a disorder, (b) how the individual values the condition influences whether the condition is seen as a proper target of medical intervention, and (c) perceived dysfunction influences judgments regarding health, disorder classification, medicalization, and medical intervention. Our findings help further illuminate the intricate interplay of factors that influence judgments about health and disease in controversial conditions. (shrink)

Good academic practice is more than the avoidance of clear-cut cheating. It also involves navigation of the gray zones between cheating and good practice. The existing literature has left students’ understanding of gray zone practices largely unexplored. To begin filling in this gap, we present results from a questionnaire study involving N = 1639 undergraduate students from seven European countries representing all major disciplines. We show that large numbers of these students are unable to identify gray area issues and lack (...) sensitivity to the context dependence of these. We also show that a considerable proportion of students have a poor understanding of concepts like plagiarism and falsification, not only in gray zone scenarios, but also in cases of relatively clear-cut cheating. Our results are similar across the faculties and countries of study, and even for students who have attended academic integrity training. We discuss the implications of this for academic integrity training. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Christopher Boorse’s Health care ethics: an introduction, Temple University Press, Philadelphia, pp 359–393, 1987; in Humber, Almeder, Totowa What is disease?, Humana Press, New York City, pp 1–134, 1997; J Med Philos, 39:683–724, 2014) Bio-Statistical Theory comprehends diseases in terms of departures from natural norms, which involve an objectively describable deviation from the proper physiological or psychological functioning of parts of the human organism. I argue that while recent revisions and additional considerations shield the BST from a number of issues (...) raised by critics, they give rise to significant new challenges. These are related to the attribution of epistemic authority, the possibility of multiple concepts in the authoritative literature, and the framing of BST as “philosophical explication.” The conclusion is that, in its current form, the BST is unable to provide a robust framework for a naturalist classification.

A connection viewed from the perspective of integration has the Bianchi identities as constraints. It is shown that the removal of these constraints admits a natural solution on manifolds endowed with a metric and teleparallelism. In the process, the equations of structure and the Bianchi identities take standard forms of field equations and conservation laws.The Levi-Civita (part of the) connection ends up as the potential for the gravity sector, where the source is geometric and tensorial and contains an explicit gravitational (...) contribution.Nonlinear field equations for the torsion result. In a “low-energy” approximation (linearity andlow energy-momentumtransfer), the postulate that only charge and velocities contribute to the source transforms these equations into the Maxwell system. Moreover, the affine geodesics become the equations of motion of special relativity with Lorentz force in the same approximation [J. G. Vargas,Found. Phys. 21, 379 (1991)]. The field equations for the torsion must then be viewed as applying to an electromagnetic/strong interaction.A classical unified theory thus arises where the underlying geometry confers their contrasting characters to Maxwell-Lorentz electrodynamics and to an Einstein's-like theory of gravity. The highly compact field equations must, however, be developed in phase-spacetime, since the connection is velocity-dependent, i.e., Finsler-like.Further opportunities for similarities with present-day physics are discussed: (a) teleparallelism allows for the formulation of the torsion sector of the theory as a flat space theory with concomitant point-dependent transformations; (b) spinors should replace Lorentz frames in their role as the subjects to which the connection refers; (c) the Dirac equation consistent with the frame bundle for a velocity-dependent metric with Lorentz signature generates a weak-like interaction in the torsion sector.

In a recent paper [J. G. Vargas and D. G. Torr, Found. Phys. 27, 599 (1997)], we have shown that a subset of the differential invariants that define teleparallel connections in spacetime generates a teleparallel Kaluza-Klein space (KKS) endowed with a very rich Clifford structure. A canonical Dirac equation hidden in this structure might be uncovered with the help of a teleparallel Kähler calculus in KKS. To bridge the gap to such a calculus from the existing Riemannian Kähler calculus (...) in spacetime, we commence the construction of a teleparallel Kähler calculus in spacetime. In the process, we notice: (a) Unknown to him, one of Einstein's equations in his attempt at unification with teleparallelism states that the interior covariant derivative of the torsion is zero. (b) A mechanism exists in the tangent bundle of teleparallel spaces for producing confinement (in the applicable cases, one would have to show why nonconfinement also occurs, rather than the other way around). (c) When the torsion is not zero, the interior covariant derivative in the sense of Kähler, δF, does not coincide with *d*F. The system (dF = 0, δF = j) rather than (dF = 0, *d*F = j) should then be used for generalizations of Maxwell's electrodynamics. (shrink)

The revised Robertson's test theory of special relativity (SR) has been constructed upon a family of sets of passive coordinate transformations in flat space-time [J. G. Vargas and D. G. Torr,Found. Phys., 16, 1089 (1986)]. In the same paper, it has also been shown that the boosts depend in general on the velocities of the two frames involved and not only on their relative velocity. The only exception to this is SR, if one has previously used an appropriate constraint (...) to remove the other relativities—like Galilean relativity—from the family.In this paper we look at these coordinate transformations in the only way there is to do so, namely as transformations in a seven-dimensional “Cartan Space” (Cartan first considered this in his dealings with Newtonian kinematics). In this space, the boosts only depend on the relative velocity of the frames. The passive coordinate transformations in each set are shown to have a nonlinear group structure isomorphic to that of the Poincaré group.The existence of a preferred frame, except in SR, makes the active transformations inequivalent to the passive ones. It is shown that the composite active-passive transformations act on a ten-dimensional space and that each member set of the family also has a group structure. As a result, one ends up with a family of mutually isomorphic 9-parameter (homogeneous) supergroups and a family of mutually isomorphic (9 + 4)-parameter (inhomogeneous) supergroups. The presence of extra parameters could be looked upon as “internal” degrees of freedom, which are, however, an offshoot of the Robertson space-time. (shrink)

The philosophical literature on sport and games has had little to say about boredom beyond presuming that sports and games can be important ways of overcoming or preventing it. But boredom is an interesting and often misunderstood phenomenon with overlooked implications in this context. Boredom has significant human value and motivates play in ways that contribute to well-being and culture, often through encouraging engaged agency and exploration of novelty. Understanding boredom can also help to clarify problems and tendencies in sports (...) and games that qualify them as havens from boredom. (shrink)

The phenomenon of ambivalence is an important one for any philosophy of action. Despite this importance, there is a lack of a fully satisfactory analysis of the phenomenon. Although many contemporary philosophers recognize the phenomenon, and address topics related to it, only Harry Frankfurt has given the phenomenon full treatment in the context of action theory - providing an analysis of how it relates to the structure and freedom of the will. In this paper, I develop objections to Frankfurt's account, (...) all revolving around the charge that his account contains a serious ambiguity between willing and identifying. With such objections in place, I then develop an analysis that avoids the difficulties and ambiguities that Frankfurt's analysis is prey to. I briefly distinguish ambivalence from other types of internal conflict. This paper aims to offer conceptual clarification on the phenomenon of ambivalence, which will then allow for discussions about the normative merits and demerits of ambivalence, the effects of ambivalence on autonomous action, and methods of resolution of ambivalence.

The idea of the philosopher-statesman finds its first literary expression in Plato's Republic, where Socrates, facing the ‘third wave’ of criticism of his ideal State, how it can be realized in practice, declares2 that it will be sufficient ‘to indicate the least change that would affect a transformation into this type of government. There is one change’, he claims, ‘not a small change certainly, nor an easy one, but possible.’ ‘Unless either philosophers become kings in their countries, or those who (...) are now called kings and rulers come to be sufficiendy inspired with a genuine desire for wisdom; unless, that is to say, political power and philosophy meet together, … there can be no rest from troubles for states.’.

In lieu of an abstract, here is a brief excerpt of the content:The Aristotelianism of Locke's PoliticsJ. S. MaloyThose, then, who think that the positions of statesman, king, household manager, and master of slaves are the same are not correct. For they hold that each of these differs not innly in whether the subjects ruled are few or many... the assumption being that there is no difference between a large household and a small city-state.... But these claims are not true.Aristotle, (...) Politics, 1252a1The Power of a Magistrate over a Subject may be distinguished from that of a Father over his Children, a Master over his Servant, a Husband over his Wife, and a Lord over his Slave. All which distinct Powers happening sometimes together in the same Man, if he be considered under these different Relations, it may help us to distinguish these Powers one from another, and show the difference betwixt a Ruler of a Common-wealth, a Father of a Family, and a Captain of a Galley.Locke, Two Treatises of Government, 2.22 [End Page 235]When the political theory of John Locke first appeared in print in 1689, the imposing authority of Aristotle stood ready to defeat it. So believed many of Locke's critics, at any rate. After his death in 1704, when it was confirmed that the internationally renowned author of An Essay Concerning Human Understanding had also written the anonymously published Two Treatises of Government, Locke was widely taken to represent a distinctive type of political theory based on individual rights and the social contract. Learned opposition to this sort of voluntaristic account of politics has often rested on Aristotle, "the Philosopher," the ancient authority on the human instinct for sociability and the hierarchal communities arising therefrom. Within the modern academy "liberals," "communitarians," and "republicans" have again made a habit of pronouncing the names of Locke and Aristotle in tones of antagonism. In broad outline the reasons have not changed in two or three centuries ago: the first stands for natural-rights individualism and the second for an organic conception of community.3What are we to make of this conventional opposition in light of the awkward fact that the second of Locke's Two Treatises, "Of Civil Government," takes the reclamation of the Aristotelian conception of political power as its principal purpose? Locke announced in the opening chapter of that essay that his chief target, Robert Filmer, had misunderstood the nature of distinctively political relationships, mainly by ignoring the differences between authority in political society and authority within the family (L 2.1–2). Locke alleged that this basic conceptual mistake of the Filmerian theory of "absolute" and "arbitrary" government was the source of its disastrous practical ramifications, which he had summed up in the first Treatise as "Chains for all Mankind" (L 1.1). Filmer, in turn, had taken Plato's side in the debate about political and familial rule which Aristotle had joined in the opening lines of his Politics (A 1252a). Though a perceptive reader long ago noticed the Aristotelianism of Locke's response to Filmer—Locke and Algernon Sidney were the "two famous men" to whom Rousseau alluded as having defended Aristotle against Filmer's Platonic notions of power—no modern scholar has attempted a full explanation of the significance of Locke's intervention in this debate.4 [End Page 236]The analysis below will show that Aristotle was the classic source for both the principal theoretic argument of Locke's second Treatise and the method employed to pursue it, i.e. using analogies of power for conceptual comparison and distinction. But my argument for the Aristotelianism of Locke's politics will rest on contextual as well as textual grounds. Not only was Locke pursuing an evident variation on the central theme of bk. 1 of Aristotle's Politics; he was far from alone in doing so. This sort of project was by the 1680s typical of radical constitutionalist writing in Europe, including not only English Whigs like Sidney and James Tyrrell but also a long line of writers on both sides of the English Channel, stretching back at least a century, who deployed a particular interpretation of Aristotle in the service...

Introduction to one of the most important, controversial, and suggestive works of moral philosophy ever written.

The current study collected orally-delivered autobiographical narratives from a sample of 44 undergraduate students. Participants were asked to produce both deceptive and non-deceptive versions of their narrative to two specific autobiographical question prompts while standing in front of a video camera. Narratives were then analyzed with Coh-Metrix software on 33 indices of linguistic cohesion. Following a Bonferroni correction for the large number of linguistic variables , results indicated that the deceptive narratives contained more explicit action verbs, less linguistic complexity, and (...) less referential coherence . The results support a theory that, in deceptive narratives, there is greater narrative distance between the self that narrates and the self that is narrated about. This suggests that narrative selves are constituted not as autonomous selves, but are subject to processes that are likely operating on a subconscious level. (shrink)

Voluntades anticipadas: desafíos éticos en el cuidado del paciente Diretivas antecipadas de vontade: desafios éticos no cuidado do paciente Advance healthcare directives are intended for the individual to personally express their will and preferences about healthcare and treatment ahead of time. This literature review aims to describe the concept and structure of advance directives and the ethical aspects involved in patient care. Using the keywords “Advance Healthcare Directive” AND “Ethical Implication” and its Spanish equivalents, five databases were accessed: ProQuest, Philosophy, (...) PubMed, Web of Science and Scielo. Publications were narrowed down to the 2010-2018 period. Thirty-one articles were obtained and read critically. Results of this review were grouped into the following categories: concept, structure, clinical situations in which advance directives apply, strengths and limitations, as well as the ethical aspects involved. End of life-related experiences in which a person loses their ability to make decisions and cannot express their wishes, so it is impossible to know their will, are more common nowadays. Most health workers are not appropriately trained in the preparation and application of advance directives, which becomes an opportunity to research and delve deeper into the subject. Advance directives are a tool that gives health workers reliable information on a patient’s values and wishes, so it is vital to train them to provide respectful quality care.

__Forging People __explores the way in which Hispanic American thinkers in Latin America and Latino/a philosophers in the United States have posed and thought about questions of race, ethnicity, and nationality, and how they have interpreted the most significant racial and ethnic labels used in Hispanic America in connection with issues of rights, nationalism, power, and identity. Following the first introductory chapter, each of the essays addresses one or more influential thinkers, ranging from Bartolomé de Las Casas on race and (...) the rights of Amerindians; to Simon Bolívar's struggle with questions of how to forge a nation from disparate populations; to modern and contemporary thinkers on issues of race, unity, assimilation, and diversity. Each essay carefully and clearly presents the views of key authors in their historical and philosophical context and provides brief biographical sketches and reading lists, as aids to students and other readers. “Latin American philosophy has a long history of engagement with issues of race, ethnicity, and nationality. To date, however, there has been no volume that focused on the contributions of the major figures in the Latin American tradition, to illustrate their connections, and to illuminate the context in which much of their work occurred. This volume fills that gap and takes an important step in remedying this shortcoming in the existing philosophical literature, and also in the literature of related fields such as Latin American studies, ethnic studies, and the cross-disciplinary work of race, ethnicity, and nationality.” —_Manuel Vargas, University of San Francisco _.

This volume -- a companion to Thomas Reid: Selected Philosophical Writings (2012) -- makes available material from Thomas Reid's autograph manuscripts and student notes of his lectures. It includes an introductory essay by Nicholas Wolterstorff.

Discovering obligations that are ascribed to them by others is potentially an important element in the development of the moral imagination of engineers. Moral imagination cannot reasonably be developed by contemplating oneself and one’s task alone: there must be some element of discovering the expectations of people one could put at risk. In practice it may be impossible to meet ascribed obligations if they are completely general and allow no exceptions — for example if they demand an unlimited duty to (...) avoid harm. But they can still serve to modify engineers’ prior ethics, for example by limiting a purely utilitarian approach to deciding who should bear risk and how much risk they should bear. Ascribed obligations can also give engineers insight into the public reaction to risks that arise from engineered systems, and the consequent expectations that the public have about how much protection is desirable and where the responsibility for this protection lies. This article analyses the case for taking ascribed obligations seriously, and reviews some of the obligations that have been ascribed in the aftermath of recent engineering failures. It also proposes ways in which ascribed obligations could be used in engineers’ moral development. (shrink)
