In this paper we ask whether approximation for abstract argumentation is useful in practice, and in particular whether reasoning with grounded semantics – which has polynomial runtime – is already an approximation approach sufficient for several practical purposes. While it is clear from theoretical results that reasoning with grounded semantics is different from, for example, skeptical reasoning with preferred semantics, we investigate how significant this difference is in actual argumentation frameworks. As it turns out, in many graphs models, reasoning with (...) grounded semantics actually approximates reasoning with other semantics almost perfectly. An algorithm for grounded reasoning is thus a conceptually simple approximation algorithm that not only does not need a learning phase – like recent approaches – but also approximates well – in practice – several decision problems associated to other semantics.

Argumentation Frameworks provide a fruitful basis for exploring issues of defeasible reasoning. Their power largely derives from the abstract nature of the arguments within the framework, where arguments are atomic nodes in an undifferentiated relation of attack. This abstraction conceals different senses of argument, namely a single-step reason to a claim, a series of reasoning steps to a single claim, and reasoning steps for and against a claim. Concrete instantiations encounter difficulties and complexities as a result of conflating these senses. (...) To distinguish them, we provide an approach to instantiating AFs in which the nodes are restricted to literals and rules, encoding the underlying theory directly. Arguments in these senses emerge from this framework as distinctive structures of nodes and paths. As a consequence of the approach, we reduce the effort of computing argumentation extensions, which is in contrast to other approaches. Our framework retains the theoretical and computational bene..

Politics is hugely complex. Some try to reduce its complexity by examining it through an ideological worldview, a one-size-fits-all prescriptive formula or a quantitative examination of as many 'facts' as possible. Yet politics cannot be adequately handled as if it were made of cells and particles: ideological views are oversimplifying and sometimes dangerous. Politics is not simply a moral matter, nor political philosophy a subdivision of moral philosophy. This book is devised as a basic conceptual lexicon for all those who (...) want to understand what politics is, how it works and how it changes or fails to change. Key concepts such as power, conflict, legitimacy and order are clearly defined and their interplay in the state, interstate and global level explored. Principles such as liberty, equality, justice and solidarity are discussed in the context of the political choices confronting us. This compact and systematic introduction to the categories needed to grasp the fundamentals of politics will appeal to readers who want to gain a firmer grasp on the workings of politics, as well as to scholars and students of philosophy, political science and history.

Plato's political thought gave rise to a number of concepts and issues - such as the idea of a normative theory, the philosophical foundation of politics, the philosopher-kings, the standard of utopian theory - which have played a significant role on Western political and philosophical thought. -/- This volume aspires to bring out Plato's concept of efficacy in a normative theory. -/- By efficacy, the author means the way in which the theory conceives of its practical realization. If in the (...) Republic this issue is particularly problematic, in the Laws, instead, the claim of realizability becomes the main concern. -/- By defining the concept of efficacy and going through the main works of Plato, this conceptual and textual analysis aims to shed a new light on Plato's political thought, which is neither a utopia, nor a short term political program, but the first normative theory encompassing a theory of efficacy.

La obra del cantautor vallenato Máximo Jiménez se mantiene más vigente que nunca. Sus canciones poseen un valor testimonial y literario que aporta a la construcción de un relato plural de Colombia y que, por lo mismo, también permite cuestionar las narrativas hegemónicas de nuestra mitología nacional en torno al conflicto político, en la medida en que concreta la voluntad colectiva del campesinado por recordar y hacer memoria de sus procesos organizativos como agremiación, así como también de hacer frente a (...) problemáticas tales como la reforma agraria, la violencia política, el gamonalismo, la inercia y el abandono estatal y la desigual tenencia de tierras, especialmente en los departamentos de Córdoba y Sucre, a partir de finales de la década del sesenta, en el marco de las reivindicaciones de la agremiación conocida como la Asociación Nacional de Usuarios Campesinos (ANUC). De forma contraria a lo que aseguran algunos pensadores, como Walter Ong sobre las culturas orales, la música de Máximo Jiménez se sitúa de forma crítica y con honda sensibilidad histórica frente a la política colombiana y sus prácticas de poder, así como también frente al panorama geopolítico e internacional de la época. En esa medida, el presente trabajo realiza un análisis sociocrítico de las canciones de Máximo Jiménez, particularmente, focalizando su manera de comprender la noción de ‘Pueblo’ y en la manera en que sus canciones establecen una relación entre sus textos y los hechos sociales que le circundan.

Intuitively, we can conceive of the existence of a conscious state as a pure activity that does not necessarily require a body (or even a brain). This idea has found new support in certain recent theories that present the possibility of a totally disconnected and disembodied consciousness. Against this hypothesis, I argue that human experience is intrinsically embodied and embedded, though in a specific way. Using Sartre’s phenomenology of the body, I first analyze the concept of consciousness as intentionality and (...) a world-disclosing activity, thus explaining how conscious activity can only be expressed through a body that is spatiotemporally related to the world. Then, I argue that bodily consciousness does not necessarily imply the actual presence of an anatomical body but, rather, a process of spatialization and temporalization (hodological space and temporal synthesis) through the “spatiotemporal body”. Finally, I test my thesis by critiquing some cases of apparent disembodied/disconnected consciousness, i.e., dreams, out-of-body experiences, and the brain-in-a-vat scenario. (shrink)

We propose a new interpretation of the equation E=mc² in special relativity by generalizing ideas of ontological emergence to fundamental physics. This allows us to propose that mass, as a property, can be considered to emerge from energy, using a well-known definition of weak ontological emergence. Einstein’s famous equation gains in this way a clearer philosophical interpretation, one that avoids the problems of previous attempts, and is fully consistent with the kinematic properties of special relativity, while yielding fresh insights concerning (...) the nature of mass.

Human cerebral organoids are three-dimensional biological cultures grown in the laboratory to mimic as closely as possible the cellular composition, structure, and function of the corresponding organ, the brain. For now, cerebral organoids lack blood vessels and other characteristics of the human brain, but are also capable of having coordinated electrical activity. They have been usefully employed for the study of several diseases and the development of the nervous system in unprecedented ways. Research on human cerebral organoids is proceeding at (...) a very fast pace and their complexity is bound to improve. This raises the question of whether cerebral organoids will also be able to develop the unique feature of the human brain, consciousness. If this is the case, some ethical issues would arise. In this article, we discuss the necessary neural correlates and constraints for the emergence of consciousness according to some of the most debated neuroscientific theories. Based on this, we consider what the moral status of a potentially conscious brain organoid might be, in light of ethical and ontological arguments. We conclude by proposing a precautionary principle and some leads for further investigation. In particular, we consider the outcomes of some very recent experiments as entities of a potential new kind. (shrink)

In previous works, an ontology of properties for quantum mechanics has been proposed, according to which quantum systems are bundles of properties with no principle of individuality. The aim of the present article is to show that, since quasi-set theory is particularly suited for dealing with aggregates of items that do not belong to the traditional category of individual, it supplies an adequate meta-language to speak of the proposed ontology of properties and its structure.

En su más reciente libro, Cuestiones de Filosofía del Lenguaje: Pragmática, David Pérez Chico (2022) nos presenta una muy interesante selección de artículos sobre diferentes temáticas actualmente trabajadas en filosofía del lenguaje. Personalmente, considero que este libro es una lectura imprescindible para cualquier lector de habla hispana que quiera introducirse en las temáticas más contemporáneamente discutidas en esa disciplina. En este marco, en el presente artículo me propongo realizar un análisis crítico de cuatro de los artículos de la compilación que (...) trabajan la temática de las emisiones evaluativas, i.e., emisiones cuya extensión depende de parámetros contextuales semánticamente no estándares.

Este trabajo tematiza la cuestión de los programas informáticos que discriminan, desde la filosofía del lenguaje. En esta disciplina, la bibliografía sobre discurso de odio ha centrado su análisis en los efectos que este produce en los grupos oprimidos. La idea central del presente trabajo será presentar una nueva noción, el discurso influenciado, que permita explicar lo que el grupo opresor es llevado a afirmar en base a la opresión sistemática. Así, el discurso influenciado permitirá tanto explicar la reproducción social (...) de los discursos de odio como enmarcar teóricamente las afirmaciones discriminatorias realizadas por los programas informáticos previamente mencionados.

Although the idea of dignity has always been applied to human beings and although its role is far from being uncontroversial, some recent works in animal ethics have tried to apply the idea of dignity to animals. The aim of this paper is to discuss critically whether these attempts are convincing and sensible. In order to assess these proposals, I put forward two formal conditions that any conception of dignity must meet and outline three main approaches which might justify the (...) application of dignity to animals: the species-based approach, moral individualism and the relational approach. Discussing in particular works by Martha Nussbaum and Michael Meyer I argue that no approach can convincingly justify the extension of dignity to animals because all fail to meet the formal conditions and do not provide an appropriate basis for animal dignity. I conclude by arguing that the recognition of the moral importance of animals and their defense should appeal to other normative concepts which are more appropriate than dignity. (shrink)

We discuss the mathematical structures that underlie quantum probabilities. More specifically, we explore possible connections between logic, geometry and probability theory. We propose an interpretation that generalizes the method developed by R. T. Cox to the quantum logical approach to physical theories. We stress the relevance of developing a geometrical interpretation of quantum mechanics.

The Spinozan theory of belief fixation holds that mentally representing truth-apt propositions leads to immediately believing them. In this paper, I explore how the theory fares as a defence of doxasticism about delusions (the view that they are beliefs). Doxasticism has been criticised on the grounds that delusions typically do not abide by rational standards that we expect beliefs to conform to. If belief fixation is Spinozan, I argue, these deviations from rationality are not just compatible with, but supportive of, (...) their status as beliefs. (shrink)

According to the received view in epistemology, inferential knowledge from non-knowledge is impossible – that is, in order for a subject to know the conclusion of their inference, they must know the essential premises from which that conclusion is drawn. In this book, Federico Luzzi critically examines this view, arguing that it is less plausible than intuition suggests and that it can be abandoned without substantial cost. In a discussion that ranges across inference, testimony and memory he analyses the (...) full range of challenges to the view, connecting them to epistemological cases that support those challenges. He then proposes a defeater-based framework which allows the phenomenon of knowledge from non-knowledge across these three epistemic areas to be better understood. His book will be of interest to a wide range of readers in epistemology. (shrink)

Recent work has demonstrated how data-driven AI methods can leverage consumer protection by supporting the automated analysis of legal documents. However, a shortcoming of data-driven approaches is poor explainability. We posit that in this domain useful explanations of classifier outcomes can be provided by resorting to legal rationales. We thus consider several configurations of memory-augmented neural networks where rationales are given a special role in the modeling of context knowledge. Our results show that rationales not only contribute to improve the (...) classification accuracy, but are also able to offer meaningful, natural language explanations of otherwise opaque classifier outcomes.

We will present a three-valued consequence relation for metainferences, called CM, defined through ST and TS, two well known substructural consequence relations for inferences. While ST recovers every classically valid inference, it invalidates some classically valid metainferences. While CM works as ST at the inferential level, it also recovers every classically valid metainference. Moreover, CM can be safely expanded with a transparent truth predicate. Nevertheless, CM cannot recapture every classically valid meta-metainference. We will afterwards develop a hierarchy of consequence relations (...) CMn for metainferences of level n. Each CMn recovers every metainference of level n or less, and can be nontrivially expanded with a transparent truth predicate, but cannot recapture every classically valid metainferences of higher levels. Finally, we will present a logic CMω, based on the hierarchy of logics CMn, that is fully classical, in the sense that every classically valid metainference of any level is valid in it. Moreover, CMω can be nontrivially expanded with a transparent truth predicate. (shrink)

There is evidence indicating that the Capgras delusion is grounded in some kind of anomalous experience. According to the endorsement model, the content of the delusion is already encoded in the Capgras subject's experience, and the delusion is formed simply by endorsing that content as veridical. Elisabeth Pacherie and Sam Wilkinson have in different ways attempted to articulate a comprehensive defence of this strategy, but here I argue that the endorsement model cannot be defended along the lines envisioned by either (...) of them. I then offer a more promising way of spelling out the model, according to which the anomalous experience implicated in Capgras is metaphorical in character. (shrink)

This paper addresses the problem of pluralism in democratic societies, by exploiting some insights from the debate about the epistemology of disagreement. First, by focusing on the permissibility of experiments on nonhuman animals for research purposes, we provide an epistemic analysis of deep normative disagreements. We understand that to mean disagreements in which epistemic peers disagree about both the substantive content of an ethical issue and the correct justificatory reasons for their contrary claims. Second, we argue for a compromise solution (...) in which the reasons for reaching it are not prudential but grounded on the recognition of epistemic peerhood. (shrink)

While some form of loss of control is often assumed to be a common feature of the diverse manifestations of addiction, it is far from clear how loss of control should be understood. In this paper, I put forward a concept of decrease in control in addiction that aims to fill this gap and thus provide a general framework for thinking about addictive behavior. The development of this account involves two main steps. First, I present a view of degrees of (...) control as the degree to which an agent would be responsive to potential or counterfactual sufficient reasons to do otherwise. Second, I sketch an account of the relevant control-undermining factors in addiction that is consonant with my proposed view of degrees of control. Being a high-level functional property, reasons-responsiveness is particularly well suited to frame an account of control-undermining factors that is doubly pluralistic: it encompasses the contribution of factors both internal and external to the agent, and it is consistent with various proposals as to the precise nature of the anomaly taking place in the psychology of addiction.

According to a shared functionalist view in philosophy of mind, a cognitive system, and cognitive function thereof, is based on the components of the organism it is realized by which, indeed, play a causal role in regulating our cognitive processes. This led philosophers to suggest also that, thus, cognition could be seen as an extended process, whose vehicle can extend not only outside the brain but also beyond bodily boundaries, on different kinds of devices. This is what we call the (...) ‘Externally Extended Cognition Thesis.’ This notion has generated a lively debate. Here, we offer a novel notion of extended cognition, according to which cognition can be seen as being realized outside the brain, but still inside the body. This is what we call the ‘Internally Extended Cognition Thesis’. Not only our thesis but also our approach while defending it is innovative. The argument we offer is supported by recent empirical findings in the life sciences and biomedicine, which suggest that the gut microbiota’s activity has a functional role in regulating our cognitive processes and behaviors. In doing so, we embrace the holobiont-perspective, according to which it is possible to claim that what we call biological individuals are not autonomous entities with clear boundaries, but should rather be seen as networks of multiple interactions among species. Thus, by analyzing different sets of evidence in light of the holobiont-perspective, we argue that the gut microbiota could be seen as a component of our organism. On the basis of the philosophical interpretation of this evidence, however, we also suggest that there are no impediments standing the way of considering the gut microbiota also as a functional extension of our cognitive system. If so, this amounts to extending cognition out of ‘our skull’, though still confining it within ‘our body’: to ‘our gut’. This is an instance of the ‘Internally Extended Cognition Thesis,’ whose benefits for an original theory of extended cognition are discussed. (shrink)

In this work, we focus on the philosophical aspects and technical challenges that underlie the axiomatization of the non-Kolmogorovian probability framework, in connection with the problem of quantum contextuality. This fundamental feature of quantum theory has received a lot of attention recently, given that it might be connected to the speed-up of quantum computers—a phenomenon that is not fully understood. Although this problem has been extensively studied in the physics community, there are still many philosophical questions that should be properly (...) formulated. We analyzed different problems from a conceptual standpoint using the non-Kolmogorovian probability approach as a technical tool. (shrink)

According to the principle of Knowledge Counter-Closure , knowledge-yielding single-premise deduction requires a known premise: if S believes q solely on the basis of deduction from p, and S knows q, then S must know p. Although prima facie plausible, widely accepted, and supported by seemingly compelling motivations, KCC has recently been challenged by cases where S arguably knows q solely on the basis of deduction from p, yet p is false or p is true but not known . I (...) explore a view that resolves this tension by abandoning KCC in the light of these challenges, and which acknowledges their force but also their limits. Adopting this view helps identify the epistemic constraints that operate on the premises of knowledge-yielding deduction, clarifies the epistemic role of deduction, and allows us to distil the kernel of truth in the motivations that are standardly taken to support KCC.

The name of Khotan (Old Khotanese hvatana-) is attested in Chinese, Niya Prakrit, Tibetan, Sogdian, and Old Uyghur. Strangely, the name has not previously been identified in Tocharian and Bactrian. This paper argues that a form of the name of Khotan is actually attested in Tocharian A and B and was borrowed from native speakers of Pre- or Old Khotanese. Moreover, the Bactrian documents may have preserved a form of the name of Khotan as well. The analysis of the newly (...) identified forms enables a fresh examination of the borrowing directions of the name of Khotan in the Tarim Basin and beyond and allows several historical and linguistic conclusions.

The terrorist attacks that struck France in 2015 had reverberations throughout the country’s intellectual fields. Among the most significant was a widespread polemic that turned around whether sociological explanations of the attacks amounted to excuses and justifications for terrorists. When prominent politicians and pundits made allegations of this nature, sociologists reacted in three main ways: most denied the allegations, others reappropriated the derogatory label of excuse, while others still accepted criticism and called for a reformation of sociology. These epistemological stances (...) can be properly understood only by studying the long history of debates around ‘sociological excuses’ in France and by analysing French sociology as a field of forces and struggles.

The social sciences are predominantly seen by their practitioners as critical endeavours, which should inform criticism of harmful institutions, beliefs and practices. Accordingly, political attacks on the social sciences are often interpreted as revealing an unwillingness to accept criticism and an acquiescence with the status quo. But this dominant view of the political implications of social scientific knowledge misses the fact that people can also be outraged by what they see as its apologetic potential, namely that it provides excuses or (...) justifications for people doing bad things, preventing them from being rightfully blamed and punished. This introduction to the special issue sketches the long history of debates about the exculpatory and justificatory consequences of social science and lays the foundations for a theory of social scientific apologia by examining three main aspects: what social and cognitive processes motivate this type of accusation, how social theorists respond to it and whether different contexts of circulation of ideas affect how these controversies unfold.

Following the proposal of a new kind of selective structural realism that uses as a basis the distinction between framework and interaction theories, this work discusses relevant applications in fundamental physics. An ontology for the different entities and properties of well-known theories is thus consistently built. The case of classical field theories—including general relativity as a classical theory of gravitation—is examined in detail, as well as the implications of the classification scheme for issues of realism in quantum mechanics. These applications (...) also shed light on the different range of applicability of the ontic and epistemic versions of structural realism. (shrink)

En el presente artículo se busca describir el rol fundamental que juega la experiencia estética en los procesos de significación de lo que se suele denominar “religión popular”. Para esta labor, tomamos como objeto de estudio la fiesta religiosa que, junto con hacer referencia a una determinada realidad empírica, nos provee de dos mediaciones conceptuales para el desarrollo de nuestro análisis: la fiesta y la imagen. De este modo, después de contextualizar nuestra reflexión en el marco de los estudios culturales (...) y la estética, procedemos a definir la lógica estético-sacramental de la fiesta religiosa a partir de los conceptos de “fiesta” e “imagen”, abordados desde el enfoque de la New Material Culture.
