It is widely acknowledged that the Galilean Relativity Principle, according to which the laws of classical systems are the same in all inertial frames in relative motion, has played an important role in the development of modern physics. It is also commonly believed that this principle holds the key to answering why, for example, we do not notice the orbital velocity of the Earth as we go about our day. And yet, I argue in this paper that the precise content (...) of this principle is ambiguous: standard presentations, in both physics and philosophy, fail to distinguish between two principles that are ultimately inequivalent, the “External Galilean Relativity Principle” (EGRP) and the “Internal Galilean Relativity Principle” (IGRP). I demonstrate that EGRP and IGRP play distinct roles in physics practice (e.g., EGRP is connected to the concept of Galilean invariance, but IGRP is not) and that many classical systems that satisfy IGRP fail to satisfy EGRP. I further show that the Relativity Principle introduced by Einstein in 1905—which is not restricted to classical systems—also leads to two inequivalent principles, an external one analogous to EGRP, and an internal one analogous to IGRP. I conclude by noting that the phenomenon originally captured by Galileo’s famous ship passage is much more general than contemporary discussions in the philosophy of symmetries suggest. (shrink)

According to the orthodox view, one can appeal to the symmetries of a theory in order to show that it is impossible to measure the properties that are not invariant under such symmetries. For example, it is widely believed that the fact that boosts are symmetries of Newtonian mechanics entails that it is impossible to measure states of absolute motion in a Newtonian world (these states vary under boosts). This paper offers an overview of the various ways by which philosophers (...) have spelled out the connection between the symmetries of a theory and the alleged impossibility of measuring some properties (the variant ones). The paper will use the case of absolute motion as a case study, and will discuss a recent unorthodox view according to which this kind of motion can actually be measured in Newtonian mechanics. The paper ends by considering some avenues by which the discussion can be further developed. (shrink)

Imagine that we are on a train playing with some mechanical systems. Why can’t we detect any differences in their behavior when the train is parked versus when it is moving uniformly? The standard answer is that boosts are symmetries of Newtonian systems. In this paper, I use the case of a spring to argue that this answer is problematic because symmetries are neither sufficient nor necessary for preserving its behavior. I also develop a new answer according to which boosts (...) preserve the relational properties on which the behavior of a system depends, even when they are not symmetries. (shrink)

In this article, we apply the literature on the ethics of choice-architecture (nudges) to the realm of virtual reality (VR) to point out ethical problems with using VR for empathy-based nudging. Specifically, we argue that VR simulations aiming to enhance empathic understanding of others via perspective-taking will almost always be unethical to develop or deploy. We argue that VR-based empathy enhancement not only faces traditional ethical concerns about nudge (autonomy, welfare, transparency), but also a variant of the semantic variance problem (...) that arises for intersectional perspective-taking. VR empathy simulations deceive and manipulate their users about their experiences. Despite their often laudable goals, such simulations confront significant ethical challenges. In light of these goals and challenges, we conclude by proposing that VR designers shift from designing simulations aimed at producing empathic perspective-taking to designing simulations aimed at generating sympathy. These simulations, we claim, can avoid the most serious ethical issues associated with VR nudges, semantic variance, and intersectionality. (shrink)

This paper attempts to be a contribution to the epistemological project of explaining complex conceptual structures departing from more basic ones. The central thesis of the paper is that there are what I call “functionally structured concepts”, these are non-harmonic concepts in Dummett’s sense that might be legitimized if there is a function that justifies the tie between the inferential connection the concept allows us to trace. Proving this requires enhancing the russellian existential analysis of definite descriptions to apply to (...) functions and using this in proving the legitimacy of such concepts. The utility of the proposal is shown for the case of thick ethical terms and an attempt is made to use it in explaining the development of natural numbers. This last move could allow us to go one step lower in explaining the genesis of natural numbers while maintaining the notion of abstract numbers as higher order entities. (shrink)

In popular culture psychopaths are inaccurately portrayed as serial killers or homicidal maniacs. Most real-world psychopaths are neither killers nor maniacs. Psychologists currently understand psychopathy as an affective disorder that leads to repeated criminal and antisocial behavior. Counter to this prevailing view, I claim that psychopathy is not necessarily linked with criminal behavior. Successful psychopaths, an intriguing new category of psychopathic agent, support this conception of psychopathy. I then consider reactive attitude theories of moral responsibility. Within this tradition, psychopaths are (...) thought to be blameless as a result of their pronounced affective deficits. Psychopaths are considered morally blind because they lack the moral emotions that make us sensitive to moral reasons. I argue that, even if they are morally blind, psychopaths remain open to forms of blame stemming from non-moral reactive attitudes. These reactive attitudes remain appropriate because psychopaths can express hateful, disgusting, or contemptible non-moral values in their judgments. (shrink)

Under semantic monism I understand the thesis “The Good is said in one way” and under semantic pluralism the antithesis “The Good is said in many ways”. Plato’s Socrates seems to defend a “semantic monism”. As only one sun exists, so the “Good” has for Socrates and Plato only one reference. Nevertheless, Socrates defends in the Philebus a semantic pluralism, more exactly trialism, of “beauty, symmetry and truth” . Therefore, metaphorically speaking, there seem to exist not only one sun, but (...) three suns. If the platonic Socrates defends a semantic monism on the one hand and pluralism on the other, how can we unite his pluralism with his monism? My thesis is that the three references are “qualities” of the one single reference, or again, speaking metaphorically, “side suns” of the single sun. In the following, I propose first an exegesis of Plato’s last written word on the Good in Phil. 65 A 1-5 by dividing it into five sentences. Second, I ask a philosophical question on this monism and the corresponding hierarchy of values. (shrink)

This article asks the question “Why did Plato not write the ‘unwritten doctrine’?” and answers it by citing a combination of two obstacles. The first derives from the limitations of the episteme available to an embodied soul about the essence of the good. Even if the dialectician has access to some kind of knowledge, the mismatch between the unchanging essence of the good and the precarious logoi which aim to identify it (and allow others some measure of access to it) (...) can never fully be overcome. At best, Socrates (or Plato) can lead souls to an incomplete account of it: It is possible that even the most expert dialectician can only have a claim to knowledge, but no absolute certainty. Another obstacle lies in the audience or readership itself: No shortcut to understanding is possible, and yet a mere written presentation, which is all they have, is just such a shortcut, and so represents an empty promise. In memory of Charles H. Kahn (1928–2023), a letter of his from September 5, 1989, concerning the question “Why did Plato not write the ‘unwritten doctrine’?” is published, along with some comments.

In Mexico, the Productive Organization Program for Indigenous Women (POPMI) seeks the empowerment of productive capacities in indigenous women. Our study analyzes POPMI outreach, focusing our attention on women beneficiaries who present a high degree of social exclusion and multidimensional poverty in the State of Veracruz. In the study area, the 542 indigenous women benefited in POPMI, presented a condition of multidimensional poverty and a degree of social exclusion: very high, high and medium, they represent only 22.19% of the total (...) beneficiaries of this program In 2010, since at the state level a total of 2,243 indigenous women were cared for. The results show that the localities where the condition of multidimensional poverty and very high, medium and high levels of social exclusion have been excluded in the coverage of POPMI. (shrink)

In this paper, we assess the impact of extended reality technologies as they relate to sexual forms of harassment. We begin with a brief history of the nature of sexual harassment itself. We then offer an account of extended reality technologies focusing specifically on psychological and hardware elements most likely to comprise what has been referred to as “the metaverse”. Although different forms of virtual spaces exist (i.e., private, semi-private, and public), we focus on public social metaverse spaces. We do (...) this to better explain how the concept of sexual harassment must be adjusted to such spaces and how approaches aimed at mitigating harassment must be sensitive to the type of metaverse spaces users utilize. We then offer a typology of sexual harassment for the metaverse focusing on three distinct forms of sexual harassment: (1) invariant (2) mixed variance or modified and (3) unique or metaverse specific. Although existing normative and legal frameworks may function well with respect to the first and, possibly, second forms of harassment, we argue such frameworks will not helpfully address metaverse-specific harassment. Ultimately, the changing nature of privately owned public spaces (POPS) which metaverses are likely to represent pose distinct ethical and regulatory challenges. (shrink)

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

This is an obituary notice on Henri Lauener (1933-2002).

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

What do we mean when we describe the history of the Caribbean as traumatic? Is it possible to use the term ‘trauma’ here in a more technical sense, or should we give it the less strict connotation of an extreme form of an event in which the past no longer stays just in the past and the future never ceases to demand something from the present? In this paper I analyze the image of the abyss, used by Édouard Glissant to (...) evoke poetically one of the beginnings of the Caribbean, as leading to a paradox on the attitude toward history: Caribbean communities have been burdened with a non-history that feels, at the same time, like too much history. I show that this image resembles the paradoxical structure of trauma developed in the works of Cathy Caruth, according to whom trauma is a paradoxical structure of experience in which the subject (or a community) is painfully possessed by an image that they have barely perceived and that is so minimal that it cannot be controlled. However, I argue, there are limits to this resemblance. I focus on the question whether the (traumatic) paradox is escapable in this region of the world, that is, whether Caribbean communities can be de-traumatized, and what are the connections of this possibility with the question, central to Glissant, of decolonization. In order to answer these questions, I analyze a central feature of the Caribbean history according to Glissant, transversality, to show in what way the paradox of history can be loosened. (shrink)

The place of Glissant’s philosophy of decolonisation in relation to Fanon and Césaire has been theorised by some authors, but the emphasis has not been placed on the fact that Glissant refers to both his predecessors as examples of the absence of a link between the two tactics of resistance – un détour [a tactical diversion] and un retour [a return]. For Glissant, both Césaire and Fanon are still diverters and not properly producers of a new reality, of a real (...) Caribbean territory and history. Thus, following previous analyses by commentators, but departing from them (or adding a new layer, the layer of spatiality that should be combined with a traditional analysis of temporality), this chapter defends the idea that Glissant locates his decolonial thought between Césaire and Fanon: it neither advocates a reconstruction that points to a past located elsewhere (Africa), nor recommends the rejection and replacement of the here/now with a different, unknown spatiality and temporality. For Glissant, the locus of resistance is located in the present and in the possibilities of decolonisation already contained in the Caribbean, although concealed and understated. This chapter begins by showing what is, according to Glissant, the necessary conjunction between the different tactics of resistance, then focuses on some of Césaire’s and Fanon’s texts in order to show why they do not offer this necessary link. The final section comes back to Glissant to analyse the notion of l’antillanité as the possibility of truly focusing on a here/now as a multilayered strategy of resistance. (shrink)

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

In Mexico, the management of public resources has been questioned by the State, and mainly the results that the public administration at its three levels (federal, state and municipal), by the lack of transparency in the application and verification of public resources. The experience that gives us the operation of different emerging programs that focused on reducing social and economic inequality in the country, we can locate them as the first attempts in the search for a solution that is complex. (...) Moving from the role of the benefactor and welfare state to the promoter of the regions and in the recognition of the focalization of priority attention areas, the path that has been taken is not only the beginning. Recognizing the public nature of public finances as a promoter of social development, we must understand it as the one assumed by the State through social, political and economic co-responsibility to solve poverty and marginalization of its own public policy orientation and vision of solution has been made since the eighties. From the above, we can point out some preliminary conclusions including the study of the indigenous language-speaking population with a high level of social exclusion in the methodology for the definition of multidimensional poverty in Mexico, will allow the allocation of public resources in the fight against poverty to be effective since it will make it possible to identify to the target population that is subject to social exclusion and marginalization. This invites us to a final reflection: What to do to address the just social demands of the indigenous population that is immersed in poverty, marginalization and exclusion? What to do so that they do not leave their communities, and if they have already done so, how to attend to the needs of family groups that are due to the expense of a remittance that may never arrive?

The phenomenon of corruption is a cancer that affects our country and that it is necessary to eradicate; This dilutes the opportunities for economic and social development, privileging the single conjunction of particular interests, political actors in non-legal agreements for their own benefit, which lead to acts of corruption. Recent studies indicate that the level of corruption present in a political system is directly related to the type of institutional structure that defines it (Boehm and Lambsdorff, 2009), as well as (...) the ineffectiveness of the control organisms (Casar, 2015; Cárdenas, 2010, Rojas, 2010, Carbonell, 2009, Restrepo, 2004), which requires citizen action to combat corruption (Sandoval, 2010, Villanueva, 2006). This work, focuses our attention on the federal public administration, presenting as a proposal to empower the citizen action in the fight against corruption and in the National Anticorruption System; the figure of Whistleblowers or generator of citizen alert, based on two fundamental principles: i) recognizing the citizen's obligation to report acts of corruption and ii) the granting by the authority of witness protection. These two actions will result in two important results: i) Consolidate the citizen's complaint to inform society about acts of corruption and ii) and the exercise of freedom of information so that society is able to be informed about acts of corruption. These actions will allow promoting and consolidating a culture of reporting acts of corruption that may constitute a crime as a fundamental pillar in the National Anticorruption System in Mexico.

Mexico, with the commissioning of the "National Crusade Against Hunger Program" in 2013, aimed at serving the population that presents both extreme poverty and food deprivation. The article aims to analyze whether the criterion of the selection of the municipalities of the State of Veracruz incorporated in the National Crusade Against Hunger Program (PNCH) show complementarity with the efforts in the fight against poverty in the social expenditure strategy applied in the Priority Attention Zones Program (ZAP) and the Priority Areas (...) Development Program (PDZP) and, particularly, the indigenous municipalities that have a greater degree of social exclusion. The adjustment of a binary logistic regression model is presented, in order to assess the incidence of contextual factors to interpret the scope of the strategy adopted by the federal government in the fight against poverty and hunger. As a result, it is evident that there is no continuity in the fight against poverty, since the municipalities included in the strategy Priority Areas of Attention and Program of Development of Priority Zones are not considered in the selection of municipalities incorporated in the National Program of Crusade Against Hunger, a situation that identifies the relationship between programs is not complementary.

Recent studies have shown that the indigenous population has been subject to social exclusion (Medel, 2016; Tetreault,2012; Rionda,2010; Del Popolo et al.,2009; World Bank,2004; Uquillas et al.,2003; Appasamy,1996). However, in the case of Mexico, there is no indicator to measure the degree of social exclusion. This article presents a methodology for estimating social exclusion index (IES) by estimating main components. Our proposal is to incorporate the index of social exclusion as a factor that can explain the current status of poverty (...) in the localities that have a high concentration of indigenous population and high economic marginalization in the state of Veracruz, and thus analyze the scope social policy to combat poverty, as the case Development Program Priority Areas (PDZP).

El fenómeno de la corrupción es un cáncer que afecta a nuestro país y que es necesario erradicar; éste diluye las oportunidades de desarrollo económico y social, privilegiando la sola conjunción de intereses particulares, de actores políticos en acuerdos no legales en beneficio propio, los cuales derivan en actos de corrupción. Estudios recientes señalan que el nivel de corrupción presente en un sistema político está directamente relacionado con el tipo de estructura institucional que lo defina (Boehm y Lambsdorff, 2009), así (...) como de la ineficacia de los organismos de control (Casar, 2015; Cárdenas, 2010; Rojas, 2010; Carbonell, 2009; Restrepo, 2004), por lo que se requiere de la acción ciudadana para combatir la corrupción (Sandoval, 2010; Villanueva, 2006). Este trabajo, centra nuestra atención en la administración pública federal, presentando como propuesta para empoderar la acción ciudadana en el combate de la corrupción y en el Sistema Nacional Anticorrupción; la figura de Whistleblowers o generador de alerta ciudadana, desde dos principios fundamentales: i) reconociendo la obligación del ciudadano de informar sobre actos de corrupción y ii) el otorgamiento por parte de la autoridad de la protección de testigos. Estas dos acciones derivarán en dos resultados importantes: i) Consolidar la denuncia ciudadana para informar a la sociedad sobre actos de corrupción y ii) y el ejercicio de la libertad de la información a fin de que la sociedad este en posibilidades de ser informada sobre actos de corrupción. Estas acciones permitirán promover y consolidar una cultura de la denuncia de actos de corrupción que pueden ser constitutivos de delito como pilar fundamental en el Sistema Nacional Anticorrupción en México.

El presente trabajo aborda el estudio de la ética de la responsabilidad en la función legislativa de la Cámara de Diputados del H. Congreso de la Unión, desde la perspectiva de la evaluación del trabajo de los diputados federales, y busca dar respuesta a la siguiente interrogante: ¿Es eficiente el trabajo de los Diputados Federales en la Cámara de Diputados? El propósito es ¿cómo medir y evaluar la actuación en la función legislativa de los Diputados Federales? y con ello, aproximarnos (...) a identificar si ¿es eficiente y ético el trabajo desempeñado por estos representantes públicos? El trabajo se integra en tres partes. En la primera se ubica el concepto de la ética de la responsabilidad y en la función legislativa. En la segunda sección se presenta la propuesta de un indicador para medir la eficiencia legislativa y se analiza el caso de los diputados federales de la LXI Legislatura que representan al Estado de Veracruz de Ignacio de la Llave. Finalmente, en la tercera parte se presenta una propuesta de acción ciudadana a partir de la información de la eficiencia legislativa y de la necesidad de exigir cumplimiento de la responsabilidad ética en la función legislativa. Como conclusiones importantes de la evaluación de la eficiencia legislativa de los diputados federales de la LXI Legislatura, nos muestra al menos dos resultados importantes: i) El índice de efectividad legislativa (IEL) muestra niveles muy bajos, tanto a nivel del pleno de la Cámara de Diputados, como a nivel del grupo de estudio de los diputados federales representantes del Estado de Veracruz. ii) En ambos casos, muestran un índice de rezago legislativo muy alto. Una alternativa es la exigencia ciudadana del cumplimiento ético de responsabilidad en la función legislativa al conocer la evaluación de resultados, misma que sirve como referencia para identificar escenarios de elección política basados en resultados.

It is often said in physics that if two models of a theory are related by a symmetry, then the two models provide (or could provide) two different representations of the very same situation, alike the case of two maps of different color for the very same city. It is also said that the situations represented by two models of a theory are indiscernible in some ways when the models in question are related by a symmetry of the theory, just (...) like the situation in the interior of the cabin of a train when the train is at rest in the station is empirically indiscernible from the situation in the interior when the train is moving uniformly (in classical mechanics, these two situations are represented by two models related by a boost). In recent years, philosophers of physics have focused a lot of attention in developing various principles that aim to elucidate these and similar remarks on symmetries, models, physical equivalence, and representation that are widespread in physics practice. The goal of the current article is to provide a critical review of these principles, and suggest a new framework for thinking about these kinds of questions. One important upshot of the paper is that questions of indiscernibility, and questions of the representational capacity of models, must be distinguished from one another. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

In this text, I consider two examples in the history of emancipation and manumission of enslaved, Black populations in the Caribbean and South America in order to theorize a colonial mode of conceiving of freedom at play in the first half of the nineteenth century. This mode is marked by the figure of the promise, enacting a notion of freedom as a constantly deferred, external compensation. Indeed, instead of an immediate decision deeming the practice of enslavement and trade of human (...) beings unacceptable, and an effective liberation of the enslaved Black populations in these different emancipation proclamations, the various histories of manumission in Latin America and the Caribbean show a long series of political and legal attempts to reduce and limit the extent of the slave trade that deferred the process of liberation for decades. Moreover, in many of these territories the practice did not end with the official proclamation of emancipation but was continued by illegal practices and mutations into legal forms of exploitation and oppression that are still operative today. After outlining this first trajectory, reconstructing the promise of manumission in the historical examples of Martinique (as read by Édouard Glissant) and La Gran Colombia and the Republic of Nueva Granada (contemporary Panamá, Colombia, Venezuela, and Ecuador), I analyze a second mode of investigation in examples of individual and collective strategies of liberation coming from the enslaved themselves, as reconstructed by contemporary feminist scholars in South America. These strategies appropriate liberation not as a promise, but as a negotiation and calculation that begins with the enslaved’s resistance to their oppressive conditions and that ultimately depends on the external concession by juridical authorities. In the third section of the chapter, I read these practices not as marronage, as they are sometimes approached, but as a different mode of turning back to these glimpses of freedom that more effectively challenge the narrative of emancipation and, with it, the promise of manumission in our present. -/- .

We aim to generate a dilemma for virtual reality-based research that we motivate through an extended case study of Judith Thomson’s (1985) Bridge variant of the trolley problem. Though the problem we generate applies more broadly than the Bridge problem, we believe it makes a good exemplar of the kind of case we believe is problematic. First, we argue that simulations of these thought experiments run into a practicality horn that makes it practically impossible to produce them. These problems revolve (...) around concepts that we call “perspectival fidelity”and “context realism.” Moral dilemmas that include features present in the Bridge variant will, as a result, be practically impossible to simulate. We also argue that, should we be wrong about the practical impossibility of creating a VR simulation of Bridge, such a simulation must face an ethical horn which renders these simulations ethically impermissible to develop or use. For these reasons, we argue that it is virtually impossible to simulate the bridge problem (and other thought experiments with similar features) both practically and ethically in VR. (shrink)

Philosophers and psychologists often claim that moral agency is connected with the ability to feel, understand, and deploy moral emotions. In this chapter, I investigate the nature of these emotions and their connection with moral agency. First, I examine the degree to which these emotional capacities are innate and/or ‘basic’ in a philosophically important sense. I examine three senses in which an emotion might be basic: developmental, compositional, and phylogenetic. After considering the evidence for basic emotion, I conclude that emotions (...) are not basic in a philosophically important sense. Emotions, I argue, are best understood as socially constructed concepts. I then investigate whether these emotions are necessary for moral agency. In order to do this I examine the philosophical and psychological literature on psychopathy and autism (two conditions defined in terms of empathic and emotional deficits). Persons with psychopathy appear incapable of distinguishing moral from non-moral norms. Additionally, while persons with autism often struggle to develop their empathic capacities, they are capable of understanding and deploying moral emotions like guilt and shame. I conclude that, in line with the conceptual act theories of emotion, that only contagion-based empathy is necessary for the acquisition of moral concepts. (shrink)

The problem of identity is central to epistemic transference. However, relative identity appears to be the only way to work out an epistemic useful notion of identity. Relative identity, on its part, is either parasitic on strict identity or not identity at all. If, on the contrary, we ought for a strict concept of identity capable of satisfying its requirements, we end up with a tautologic and epistemic worthless category. The paper provides an answer to this problem, which, while working (...) with a strict notion, shows how it might still serve epistemic purposes. In doing so, it shows how a formal reconstruction of our objectual world and the identities we refer to poses a workable model upon which our messy epistemic one acquires stability. The paper focuses primarily on the Geach-Quine discussion on identity. (shrink)

The present paper deals with the ontological status of numbers and considers Frege ́s proposal in Grundlagen upon the background of the Post-Kantian semantic turn in analytical philosophy. Through a more systematic study of his philosophical premises, it comes to unearth a first level paradox that would unset earlier still than it was exposed by Russell. It then studies an alternative path, that departin1g from Frege’s initial premises, drives to a conception of numbers as synthetic a priori in a more (...) Kantian sense. On this basis, it tentatively explores a possible derivation of basic logical rules on their behalf, suggesting a more rudimentary basis to inferential thinking, which supports reconsidering the difference between logical thinking and AI. Finally, it reflects upon the contributions of this approach to the problem of the a priori. (shrink)

"Paraconsistent Belief Revision Based on a Formal Consistency Operator" delves into Belief Revision—a significant area of research in Formal Philosophy that uses logic to model the ways in which human and artificial agents modify their beliefs in response to new information and examines how these changes can be considered rational. -/- Originally authored as a PhD thesis (previously published in Portuguese), this work provides a novel epistemic interpretation of Paraconsistency through Paraconsistent Belief Revision systems. It explores the concept of paraconsistency (...) from the standpoint of epistemic attitudes of acceptance and rejection. -/- This work challenges the traditional notion that accepting a new belief requires retracting its negation from the current epistemic state. The author contends that such reflexive retraction goes against the principle of informational economy, which is a crucial aspect of rationality in the context of belief change. Consequently, the phenomenon of paraconsistency is further examined from this fresh perspective of belief change, shedding light on the complexities of the Logics of Formal Inconsistency (LFIs). These LFIs provide the foundational logic, offering a comprehensive framework for understanding and implementing paraconsistent principles within belief revision systems. -/- This thesis was supervised by Marcelo Esteban Coniglio and co-supervised by Márcio Moretto Ribeiro, as part of Rafael Rodrigues Testa's doctoral studies at the University of Campinas (Unicamp), Brazil.

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

En una primera parte expondré la crítica pragmatista a la visión tradicional del lenguaje; luego, contrastaré las visiones dentro de las que critican a la tradición: contextualismo y contextualismo radical. En una segunda expondré el tipo de semántica que se podría sostener bajo esta concepción del lenguaje: una semántica no proposicionalista. Finalmente, quisiera proponer que, así como en las ciencias sociales el localismo metodológico plantea la emergencia de entidades colectivas (ya sean las clases o instituciones) —sin ser meramente epifenomenales, que (...) no obstante son realizadas y en principio deben poder ser reducidas a la agencia de actores racionales—, para el caso del lenguaje sería similar. Esto llama a recoger cierto espíritu en Saussure, que buscó otorgar a la ciencia lingüística un objeto de estudio con autonomía. (shrink)

The purpose of this essay is to look at whether Aquinas teaches in De veritate [DV], q. 1, a. 4, that truth is a form inherent in things. I take up this investigation because I am examining Lawrence Dewan's account of Aquinas's teaching on truth.1 On Dewan's account, a significant development occurs in Aquinas's teaching as regards truth as it is found in things. Before the Summa theologiae [ST], Aquinas thought that in addition to truth being in the intellect, it (...) was also in things. In ST, most explicitly in I, q. 16, a. 6, Aquinas no longer thinks that it is in things, but only in the mind. When Dewan says that before the ST truth is "in things" and in the ST it is not "in things," in both cases, by "in things," Dewan means "as a form inherent in things." What exactly this means for Dewan will be gradually brought out as I examine the text Dewan thinks most clearly teaches that truth is a form inherent in things: DV, q. 1, a. 4. (shrink)

Paraconsistency is the study of logical systems with a non-explosive negation such that a pair of contradictory formulas (with respect to such negation) does not necessarily imply triviality, discordant to what would be expected by contemporary logical orthodoxy. From a purely logical point of view, the significance of paraconsistency relies on the meticulous distinction between the general notions of contradictoriness and triviality of a theory—respectively, the fact that a given theory proves a proposition and its negation, and the fact that (...) a given theory proves any proposition (in the language of its underlying logic). Aside from this simple rationale, the formal techniques and approaches that meet the latter definitional requirement are manifold. Furthermore, it is not solely the logical-mathematical properties of such systems that are open to debate. Rather, there are several foundational and philosophical questions worth studying, including the very question about the nature of the contradictions allowed by paraconsistentists. This entry aims to advance a brief account of some distinct approaches to paraconsistency, providing a panorama on the development of paraconsistent logic. (shrink)

In this paper, we will introduce a novel argument (the "Region Argument") that objects do not have frame-independent shapes in special relativity. The Region Argument lacks vulnerabilities present in David Chalmers' argument for that conclusion based on length contraction. We then examine how views on persistence interact with the Region Argument. We argue that this argument and standard four-dimensionalist assumptions entail that nothing in a relativistic world has any shape, not even stages or the regions occupied by them. We also (...) argue that endurantists have viable ways of preserving shape despite the Region Argument. The upshot of these arguments is that contrary to conventional wisdom, considerations about shape in relativity support endurantism rather than four-dimensionalism. We conclude by examining the implications of our discussion for the debate over Edenic shapes, noting that endurantists have a satisfying response to skeptical arguments about Edenic shapes similar to the one they have against the Region Argument.

The present paper 1departs from the discussion on the foundation of morality in Discourse Ethics (DE) and the criticism raised against it, coming to reconstruct in a somewhat different way the foundational process. A first section is dedicated to analysing the difficulties of Habermas distinction between morality and ethics and the criticism raised against it, questioning a) the possibility to set the difference in the distinction between norms and values and b) the presumed neutrality of DE regarding ethical evaluations. A (...) second section revisits the foundational proposal of DE. First of all, it provi- des an interpretation of the Kantian proposal that makes the universalization of norms subservient to the idea of human beings as ends in themselves. It then considers a) the subsistence of Kantian moral reasoning in its architectonic and b) suggests a formal structure in practical thinking that integrates in hierarchical modus Kantian, discursive and contextually determined evaluative conceptions.

From our perspective, we believe that it is necessary to abandon the idea that all those who suffer from SI or SA are mentally ill, which causes them to be stigmatized and subjected to psychiatric treatment, when what they need is a different vision of life as well as adaptive strategies to employ a new philosophy. Public policies should consider implementing programs that reinforce cognitive flexibility in addition to character strengths.

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

Consensus in the contemporary philosophical literature has it that conserved quantity theories of causation such as that of Dowe [2000]—according to which causation is to be analysed in terms of the exchange of conserved quantities (e.g., energy)—face damning problems when confronted with contemporary physics, where the notion of conservation becomes delicate. In particular, in general relativity it is often claimed that there simply are no conservation laws for (say) total-stress energy. If this claim is correct, it is difficult to see (...) how conserved quantity theories of causation could survive. In this article, we resist the above consensus and defend conserved quantity theories from this conclusion, at least when focusing on the apparent problems posed by general relativity. We argue that this approach to causation can continue to be defended in general relativity, once one appreciates (a) the availability of approximate symmetries in generic general relativistic spacetimes, and (b) the role of modelling and idealisation in that theory. Given these points, conserved quantity theories of causation must stand or fall on other grounds. (shrink)

Abstracts The aim of the paper is to propose an alternative model to realist and non-cognitive explanations of the rule-guided use of thick ethical concepts and to examine the implications that may be drawn from this and similar cases for our general understanding of rule-following and the relation between criteria of application, truth and correctness. It addresses McDowell’s non-cognitivism critique and challenges his defence of the entanglement thesis for thick ethical concepts. Contrary to non-cognitivists, however, I propose to view the (...) relation between the two terms of the entanglement as resulting from the satisfaction of a previously applied moral function. This is what I call a “Three-Fold Model”. (shrink)

ABSTRACT This article offers the first step in an ongoing project of revisiting the foundations of latinidad and lo latinoamericano by focusing on the exclusions enacted by the history of these concepts and the cultural and political identity that comes with them. In conversation with Susana Nuccetelli and Omar Rivera, the author focuses on two emblematic authors in the history of Latin American philosophy (Simón Bolívar and José de Vasconcelos) that are usually read as offering a novel, liberatory conception of (...) the Latin American reality/identity, categorically different from European and Anglo-American conceptions. This common reading of some of the foundational texts on Latin American identity, however, conceals not only the active, textual removal of Blackness in the construction of this identity, but also the literal subtraction of Black bodies, lives, and histories from the Latin American nations and communities. Both of these elements are an explicit part of the philosophical programs of Bolívar and Vasconcelos. The article shows how the thought and political practice of these two authors, celebrated in different ways as foundational of what we understand as Latin America today, exemplify the exclusionary historical demarcation of latinidad.

I will review the argument from complexity of the phenomena represented by Hayek (1967) that asserts that the human phenomena are, in some way, inherently complex, thus, that the laws in social sciences are not available in principle; and by Scriven (1956), who asserts a more elaborate version of the argument from complexity, given space for the possibility that the complexity is not intrinsic to the social phenomena, but that they are constitutive to the level of description that we are (...) interested in. Against both, following McIntyre (1993) I will hold that they would be, by one hand, idealizing the scientific practice and, by the other hand, not being able to explain the social phenomena to the level that we are interested in because they end up by eliminating it. Then, in a second part, I will expose the role of explanation in historical materialism (from an analytical marxist perspective) trying to conciliate the functionalism exposed by Cohen (2001) and the methodological pluralism of Little (1991). Historical materialism, by modifying the conception of the constitution of society (substituting the methodological individualism for a structural analysis with a primacy of the socio-economical social relations) allows us even to lay the necessary foundations for identifying, in a non-abstract nor idealized way, the rational agency of individuals that constitute the social classes. This proves an advantage over methodological individualism in that it does not eliminates the phenomena that are being explained. (shrink)

*Winner of the American Philosophical Association's 2020 Essay Prize in Latin American Thought* This essay offers a novel account of the secularity of Latin American liberation philosophy. It challenges the accepted notion that liberation philosophy applies the methods and approaches of Latin American liberation theology to the philosophical arena, thus putting liberation theology on secular grounds. While this formulation is true insofar as liberation philosophy is not bound by the hermeneutics of any particular religious tradition, this formulation could be misconstrued (...) given that liberation philosophy does not premise such secularization in an undialectical understanding of secularity as secularism that disavows religion. Rather, liberation philosophy’s secularity is dialectical in that it requires constant engagement with re-ligion, not in the hermeneutics of any specific tradition but with “the traditional question of the Absolute.” Due to this often-misunderstood element of liberation philosophy, it has frequently been “ghettoized and relegated to the ‘safe’ area of theological studies,” as Eduardo Mendieta argues. However, I contend that liberation philosophy’s secular grounds offer an original contribution to philosophy as a decolonial and postsecularist liberation philosophy, one that conceives of secularism as an aspect of coloniality to be overcome, an obstacle rather than a benefit for Latin American philosophers seeking to gain a better understanding of our historical conditions.
