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.

Can addiction be credibly invoked as an excuse for moral harms secondary to particular decisions to use drugs? This question raises two distinct sets of issues. First, there is the question of whether addiction is the sort of consideration that could, given suitable assumptions about the details of the case, excuse or mitigate moral blameworthiness. Most discussions of addiction and moral responsibility have focused on this question, and many have argued that addiction excuses. Here I articulate what I take to (...) be the best argument for this view, based on the substantial difficulty that people with severe addiction experience in controlling drug-related behavior. This, I argue, may in some cases be sufficient to ground a mitigating excuse, given the way in which addiction undermines agents’ responsiveness to relevant moral reasons to do otherwise. Much less attention has been devoted to a second set of issues that critically affect the possibility of applying this mitigating excuse in particular cases, derived from the ambivalent nature of agential control in addiction. In order to find a fitting response to moral harm, the person with the right standing to blame must make a judgment about the extent to which the agent possessed certain morally relevant capacities at the time of the act. In practice, this will often prove tremendously difficult to assess. The ethical challenge for the person with the right standing to blame is fundamentally one of making a judgment about matters that seem underdetermined by the available evidence. (shrink)

This chapter explores Michel Foucault's contribution to a critical assessment of modern and contemporary psychiatric practice. It focuses firstly on the History of Madness : the social, political, cultural, epistemological construction of the object "psychiatric patient" and "psychiatric pathology"; the gradual historical shift from "madness" to "psychiatric pathology" and its social and epistemological consequences; the horizons and limits of the romantic task Foucault assumes on this basis ; the critique Jacques Derrida formulated about this project, and particularly about Foucault's reading (...) of Descartes. Secondly, it examines Foucault's course on Psychiatric Power, focusing on the sociopolitical consequences of this medicalization process: i.e., the construction of the object "psychiatric patient" as "disciplinated bodies", and the general context of this anthropological metamorphosis Foucault studied in his books Discipline and Punish, The Will to Knowledge, and in his course Naissance de la biopolitique.

During the last two decades, a sharp re-reading of St. Paul’s letters allowed several thinkers to embed a messianic element in their political philosophy. In these readings, the messianic refusal of the world and its laws is understood through the suspensive act of ‘subtraction’ – a movement of withdrawal which nonetheless proved too often ineffective when translated in political practice. -/- After having analysed Agamben’s declension of Subtraction in terms of ‘inoperativity’, this article focuses on the notion of Parousia as (...) a key element to understand his anti-utopian account of messianic time. In contrast with Agamben’s reading, Bloch’s interpretation of the Pauline Parousia envisages the messianic event as infra-historical, but at the same time opened to ultimate (meta-historical) purposes. Bloch’s messianic call – I argue – takes the form of mediation, a correction of subtraction towards the direction of a more committed political engagement. I conclude suggesting that the concrete implementations of this mediation perform their emancipatory function in so far as they assume the character of practical ethics, with the attention directed to the underprivileged and marginalised.

This work explores issues with the eliminativist formulation of ontic structural realism. An ontology that totally eliminates objects is found lacking by arguing, first, that the theoretical frameworks used to support the best arguments against an object-oriented ontology (quantum mechanics, relativity theory, quantum field theory) can be seen in every case as physical models of empty worlds, and therefore do not represent all the information that comes from science, and in particular from fundamental physics, which also includes information about local (...) interactions between objects. Secondly, by giving a critical assessment of the role of symmetries in these fundamental physical theories; and, lastly, by warning about unfounded metaphysical assumptions. An argument is made for a moderate form of structural realism instead, one in which objects play the fundamental role of representing symmetries and bearing their conserved charges, and of participating in the network of interactions observed in the world.

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.

"'Tutta la nostra vita è un esercizio alla visione dell'Uno' : affrontando il pròblema per eccellenza della tradizione neoplatonica, il rapporto tra Unità e Molteplicità, il testo tenta di rinvenire il ligamen essenziale che muove le riflessioni di tre grandi pensatori della tarda antichità, cioè Plotino, Proclo e Dionigi Areopagita; questo, all'interno di una prospettiva teoretica, critica ed ermeneutica che tiene conto anche dei guadagni filosofici conseguiti da Hegel, Gentile e Severino, e dalla poesia pensante di Dante. Nello sforzo di (...) cogliere lo Stesso che si agita nelle differenze di cui si costituisce il mondo, si offre, nel corso dell'analisi, una disamina dei principali nodi aporetici che una metafisica henologica evoca: Uno e Tutto, Infinito e finito, processione e conversione, Eternità e tempo, immagine e linguaggio, Immediato e mediato. In particolare, il filo rosso che guida queste specificazioni è rintracciato nell'inesausta dialettica tra Pensiero ed Essere, da cui e in cui, in grazia di una 'magia che tutto produce', l'ignoranza umana si apre all'Altro-non-Altro, rendendosi divina"--.

Degrowth is the literal translation of 'decroissance', a French word meaning reduction. Launched by activists in 2001 as a challenge to growth, it became a missile word that sparks a contentious debate on the diagnosis and prognosis of our society. 'Degrowth' became an interpretative frame for a new (and old) social movement where numerous streams of critical ideas and political actions converge. It is an attempt to re-politicise debates about desired socio-environmental futures and an example of an activist-led science now (...) consolidating into a concept in academic literature. This article discusses the definition, origins, evolution, practices and construction of degrowth. The main objective is to explain degrowth's multiple sources and strategies in order to improve its basic definition and avoid reductionist criticisms and misconceptions. To this end, the article presents degrowth's main intellectual sources as well as its diverse strategies (oppositional activism, building of alternatives and political proposals) and actors (practitioners, activists and scientists). Finally, the article argues that the movement's diversity does not detract from the existence of a common path. (shrink)

According to Marshall et al. (2024), some of the patients who refuse to stay in observation after being resuscitated following an opioid overdose are likely not making an autonomous choice. While I do not intend to dispute this claim, it merits discussion what is the concept of autonomy at play in making this assessment. I contend that the concept at work is more substantive than Marshall et al. acknowledge—and more substantive, too, than the form of autonomy usually thought to underpin (...) the moral justification of the requirement of informed consent .

A restrictive view of self-control identifies exercises of self-control with synchronic intrapsychic processes, and pictures diachronic and externally-scaffolded strategies not as proper instances of self-control, but as clever ways of avoiding the need to exercise that ability. In turn, defenders of an inclusive view of self-control typically argue that we should construe self-control as more than effortful inhibition, and that, on grounds of functional equivalence, all these diverse strategies might be properly described as instances of self-control. In this paper, I (...) take a fresh look at this debate by focusing on cases of addiction. I argue that addicted agents face a paradigmatic sort of self-control challenge, which makes addiction an important test case for theories of self-control. And I discuss evidence that highlights both the unreliability of synchronic intrapsychic strategies and the crucial role that is played by diachronic and externally-scaffolded strategies in successful attempts at achieving abstinence by addicted individuals. Abstaining addicts are a paradigmatic case of agents who successfully exercise self-control, and they mostly do so by relying on diachronic and externally-scaffolded strategies. This, I argue, lends further support to an inclusive view of self-control. (shrink)

It is often assumed that, except perhaps in a few rare cases, people with addiction can be aptly held responsible for having acquired the condition. In this chapter, I consider the argument that supports this view and draw attention to a number of challenges that can be raised against it. Assuming that early decisions to use drugs were made in possession of normal-range psychological capacities, I consider the key question of whether drug users who later became addicted should have known (...) that addiction was a likely outcome of their decisions to use drugs in a way that makes them blameworthy for their lack of foresight. I focus on three different points of contention surrounding this claim: how likely the outcome to be predicted was, how tolerable risk should be weighed against the expected value of decisions to use, and how reliable the relevant predictive abilities of the average person are. Once we consider in some detail what would have to be true in order for someone to be aptly held responsible for becoming addicted, the prospects for making a convincing case to that effect look, I argue, somewhat more uncertain than they might at first appear.

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.

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)

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.

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.

Artificial intelligence (AI) is becoming part of the everyday. During this transition, people’s intention to use AI technologies is still unclear and emotions such as fear are influencing it. In this paper, we focus on autonomous cars to first verify empirically the extent to which people fear AI and then examine the impact that fear has on their intention to use AI-driven vehicles. Our research is based on a systematic survey and it reveals that while individuals are largely afraid of (...) cars that are driven by AI, they are nonetheless willing to adopt this technology as soon as possible. To explain this tension, we extend our analysis beyond just fear and show that people also believe that AI-driven cars will generate many individual, urban and global benefits. Subsequently, we employ our empirical findings as the foundations of a theoretical framework meant to illustrate the main factors that people ponder when they consider the use of AI tech. In addition to offering a comprehensive theoretical framework for the study of AI technology acceptance, this paper provides a nuanced understanding of the tension that exists between the fear and adoption of AI, capturing what exactly people fear and intend to do.

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)

Resumen: 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.: The aim of this article is to describe the fundamental role of the aesthetic experience in the processes of signification of what is usually called “popular religion”. In order to achieve this, we define as the object of our study the religious feast, which, apart from referring to a concrete empirical reality, provides us with two conceptual mediations for our analysis: feast and image. Thus, following a contextualization of our reflection on the field of cultural studies and aesthetics, we proceed to define the aesthetic-sacramental logic of the religious feast on the basis of the concepts “feast” and “image”, from the perspective of the New Material Culture approach.

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)

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.

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)

En este trabajo reconstruyo la estructura argumentativa del asociacionismo coercionista defendido por Michael Blake, que consta de dos premisas, una normativa y otra empírica. Sostengo que ambas premisas pueden ser rechazadas, de manera indirecta (en el caso de la premisa empírica) o directa (en el caso de la premisa normativa). La conclusión es que el asociacionismo coercionista no prueba la existencia de una discontinuidad normativa entre el plano doméstico y el plano global.

In this paper I will evaluate the normative assumptions of Nozick's experience machine. I try to show that the intrinsic value that experiment gives to objectivity should be rejected from utilitarianism and that subjectivity counts as a necessary and sufficient condition for moral evaluation. I also conclude that satisfaction preferences utilitarianism to stay within the boundaries of utilitarianism should be considered as broad mental states consequentialism.

In a very short article, James Sterba argues that there is a moral duty to sacrifice one’s life to save the lives of others. Sterba justifies this duty by drawing an analogy with a series of cases in which some degree of sacrifice would be commonly accepted for the benefit of third parties. In this paper, I argue that Sterba’s argument reaches the correct conclusion, but is invalid. In addition, I point out two different arguments to support the existence of (...) a duty to sacrifice one’s life to save the lives of others. (shrink)
