In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

In some recent articles, Cobreros, Egré, Ripley, & van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a nontransitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of Cut (...) involving semantic notions. In this article we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have nontrivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this article is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this article, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be nontrivially achieved if self-reference is expressed through identities.

Anti-exceptionalism about logic states that logical theories have no special epistemological status. Such theories are continuous with scientific theories. Contemporary anti-exceptionalists include the semantic paradoxes as a part of the elements to accept a logical theory.

But even if the data are not enough to adopt one of these logics, there are other elements to evaluate the revision of classical logic.

When discussing Logical Pluralism several critics argue that such an open-minded position is untenable. The key to this conclusion is that, given a number of widely accepted assumptions, the pluralist view collapses into Logical Monism. In this paper we show that the arguments usually employed to arrive at this conclusion do not work. The main reason for this is the existence of certain substructural logics which have the same set of valid inferences as Classical Logic—although they are, in a clear (...) sense, non-identical to it. We argue that this phenomenon can be generalized, given the existence of logics which coincide with Classical Logic regarding a number of metainferential levels—although they are, again, clearly different systems. We claim this highlights the need to arrive at a more refined version of the Collapse Argument, which we discuss at the end of the paper. (shrink)

To make the case for non-conceptualism, Heck draws on an apparent dichotomy between linguistic and iconic representations. According to Heck, whereas linguistic representations have conceptual content, the content of iconic representations is non-conceptual. Based on the case of cartographic systems, the authors criticize Heck’s dichotomous distinction. They argue that maps are composed of semantically arbitrary elements that play different syntactic roles. Based on this, they claim that maps have a predicative structure and convey conceptual content. Finally, the authors argue that, (...) despite their differences, maps and sentences can logically interact with each other through heterogeneous inferences. These considerations not only challenge the view that conceptual content and inferential processes necessarily involve linguistic representations; furthermore, they provide a new perspective for thinking about maps, their semantics and syntax, and their interaction with linguistic systems.

En este complejo futuro que se nos predice, no solo se nos podrá superar en nuestras capacidades intelectuales o físicas, incorporando a nuestro entorno y a nuestro propio cuerpo un ingente aparataje tecnológico, sino que se nos podrá mejorar, y ello, incluso, antes de nacer, interviniendo directamente sobre el embrión. La naturaleza de lo humano se pone en cuestión, sobre todo, cuando la alteramos en su propia esencia, no solo en su entorno, y, además, desde su propio inicio. Se trata, (...) pues, de una disrupción y alteración sustancial ad intra del ser humano, no ad extra, como ocurre con la tecnología, aún cuando esta también tiene, obviamente, muchos efectos en el interior de aquél. Los cambios que se derivan de la Biotecnología y, concretamente, de la edición genómica, por un lado, ofrecen un enorme potencial para desarrollar nuevos conceptos, métodos y novedosas aplicaciones para los urgentes retos y necesidades de la sociedad. Por el otro lado, tales biotecnologías son percibidas como si tuvieran el potencial de desafiar y, a veces, desdibujar las actitudes, valores y modelos culturales de la propia sociedad. A tal reto no puede estar, obviamente, ajeno el Derecho en atención a los valores, intereses y derechos en conflicto. Si la pregunta que debemos nuevamente formularnos es qué es el hombre o qué es la naturaleza humana, el Derecho debe también ofrecer respuestas que permitan dar un sentido jurídico contemporáneo a tal esencia, preguntas que conectan directamente con el propio concepto jurídico de dignidad, no solo en cuanto valor ontológico del ser humano, sino también, recogiendo los términos explícitos del artículo 10.1 de nuestra Constitución, en cuanto fundamento del orden político y de la paz social.

Consciousness represents the core of the new paradigm, the unitary, systemic vision, and comprehension that emerges in every field of science, culture, and spirituality. For centuries, consciousness has been divided from matter, the soul from the physical body. Now, in this historical beginning of globalization, we need a new holistic model, a global paradigm based on consciousness that can explain the unitary evolutionary process, the psychosomatic unity of human being, the neurophysiological roots of harmony between peoples and the way to (...) personal and collective evolution of consciousness in order to realize a more conscious, peaceful, and sustainable planetary future. Consciousness is the key of human evolution. (shrink)

It is widely accepted that classical logic is trivialized in the presence of a transparent truth-predicate. In this paper, we will explain why this point of view must be given up. The hierarchy of metainferential logics defined in Barrio et al. and Pailos recovers classical logic, either in the sense that every classical inferential validity is valid at some point in the hierarchy ), or because a logic of a transfinite level defined in terms of the hierarchy shares its validities (...) with classical logic. Each of these logics is consistent with transparent truth—as is shown in Pailos —, and this suggests that, contrary to standard opinions, transparent truth is after all consistent with classical logic. However, Scambler presents a major challenge to this approach. He argues that this hierarchy cannot be identified with classical logic in any way, because it recovers no classical antivalidities. We embrace Scambler’s challenge and develop a new logic based on these hierarchies. This logic recovers both every classical validity and every classical antivalidity. Moreover, we will follow the same strategy and show that contingencies need also be taken into account, and that none of the logics so far presented is enough to capture classical contingencies. Then, we will develop a multi-standard approach to elaborate a new logic that captures not only every classical validity, but also every classical antivalidity and contingency. As a€truth-predicate can be added to this logic, this result can be interpreted as showing that, despite the claims that are extremely widely accepted, classical logic does not trivialize in the context of transparent truth.

Past research showed that the ability to focus on one’s internal states positively correlates with the self-regulation of behavior in situations that are accompanied by somatic and/or physiological changes, such as emotions, physical workload, and decision-making. The analysis of moral oriented decision-making can be the first step for better understanding the legal reasoning carried on by the main players in the field, as lawyers are. For this reason, this study investigated the influence of the decision context and interoceptive manipulation on (...) the moral decision-making process in the legal field gathering the responses of two groups of lawyers. A total of 20 lawyers were randomly divided into an experimental group, which was explicitly required to focus the attention on its interoceptive correlates, and a control group, which only received the general instruction to perform the task. Both groups underwent a modified version of the Ultimatum Game, where are presented three different moral conditions and three different offers. Results highlighted a significant increase of Acceptance Rate in those offers that should be considered more equal than fair or unfair ones, associated with a general increase of Reaction Times in the equal offers. Furthermore, the interoceptive manipulation oriented the Lawyers toward a more self-centered decision. This study shows how individual, situational, contextual, and interoceptive factors may influence the moral decision-making of lawyers. Future research in the so-called Neurolaw field is needed to replicate and expand current findings. (shrink)

The main idea that we want to defend in this paper is that the question of what a logic is should be addressed differently when structural properties enter the game. In particular, we want to support the idea according to which it is not enough to identify the set of valid inferences to characterize a logic. In other words, we will argue that two logical theories could identify the same set of validities, but not be the same logic.

A metainference is usually understood as a pair consisting of a collection of inferences, called premises, and a single inference, called conclusion. In the last few years, much attention has been paid to the study of metainferences—and, in particular, to the question of what are the valid metainferences of a given logic. So far, however, this study has been done in quite a poor language. Our usual sequent calculi have no way to represent, e.g. negations, disjunctions or conjunctions of inferences. (...) In this paper we tackle this expressive issue. We assume some background sentential language as given and define what we call an inferential language, that is, a language whose atomic formulas are inferences. We provide a model-theoretic characterization of validity for this language—relative to some given characterization of validity for the background sentential language—and provide a proof-theoretic analysis of validity. We argue that our novel language has fruitful philosophical applications. Lastly, we generalize some of our definitions and results to arbitrary metainferential levels. (shrink)

Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) (...) logic programs. It turns out that none of the existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle. (shrink)

Can there be two things that are completely indistinguishable? This simple question has raised numerous debates throughout the history of philosophy and science. The principle of the identity of indiscernibles claims that no two things can be completely indiscernible. But this thesis has been challenged in quantum physics and continues to be a hot topic in cutting edge areas of mathematics. The question has gained a renewed interest with the possibility of harnessing indistinguishability as a resource in quantum information tasks. (...) This theme issue is devoted to understanding identity and indistinguishability in philosophy and science, gathering an interdisciplinary group of experts in the field. It will allow readers of diverse disciplines to have an updated introduction to the topic. (shrink)

The relations between the majority and minorities in a democracy have been standardly viewed as the main subject matter of toleration: the majority should refrain from using its dominant position to interfere with some minorities’ practices or beliefs despite its dislike or disapproval of such practices or beliefs. Can the idea of toleration provide us with the necessary resources to understand and respond to the problems arising out of majority/minorities relations in a democracy? We reply in the negative and make (...) two main claims: first, that resorting to toleration is not enough to make sense of the problems deriving from the unequal participation of minorities in society, and, second, that it risks sanctioning the asymmetric relation between the majority and minorities informed by the negative judgement of the former towards some belief or practice of the latter. We suggest resorting instead to the idea of equal opacity respect for persons: all persons should be treated equally as moral agents, in accordance with their equally possessing the capacity for self-legislation, and as if they were opaque to our judgement for all those properties of theirs which exceed moral agency. Looking at the majority/minorities relations through such a lens enables us to understand (and appropriately respond to) what is problematic in such relations: the majority often fails to treat minorities as moral agents by failing to take their voices into account on an equal footing, by seeing them merely as recipients of certain provisions affecting them rather than their authors, and by considering them as legitimately exposed to the majority’s (negative) judgment. The purchase of our argument is illustrated by reference to two minorities whose treatment is paradigmatic of the problematic nature of majority/minorities relations across Europe: Muslims and Roma.

In this paper we present a framework for the dynamic and automatic generation of novel knowledge obtained through a process of commonsense reasoning based on typicality-based concept combination. We exploit a recently introduced extension of a Description Logic of typicality able to combine prototypical descriptions of concepts in order to generate new prototypical concepts and deal with problem like the PET FISH (Osherson and Smith, 1981; Lieto & Pozzato, 2019). Intuitively, in the context of our application of this logic, the (...) overall pipeline of our system works as follows: given a goal expressed as a set of properties, if the knowledge base does not contain a concept able to fulfill all these properties, then our system looks for two concepts to recombine in order to extend the original knowledge based satisfy the goal.

In this work we present a dynamical approach to quantum logics. By changing the standard formalism of quantum mechanics to allow non-Hermitian operators as generators of time evolution, we address the question of how can logics evolve in time. In this way, we describe formally how a non-Boolean algebra may become a Boolean one under certain conditions. We present some simple models which illustrate this transition and develop a new quantum logical formalism based in complex spectral resolutions, a notion that (...) we introduce in order to cope with the temporal aspect of the logical structure of quantum theory.

Si el ser humano no es un mero cúmulo de sentimientos ni una amalgama de sensaciones que se van configurando según los diversos momentos que tejen su devenir vital, ¿cuál es su auténtico yo? ¿Cómo se emprende esa búsqueda interior que nos permite hallar la esencia que se esconde en cada recodo de nuestra existencia? Son muchas las personas que no se han conformado con vivir abosortas ante el espectáculo de "lo que acontece", y que han buscado atender esa necesidad (...) intrínseca de "ir más allá", esculpiendo horizontes que rompen los moldes de la facticidad e insinúan la existencia de un ser que traspasa las fronteras de la contingencia en la que, sin embargo, parecemos estar atrapados inevitablemente. Indagar en la esencia misma de la experiencia humana para hallar su sentido más profundo nos dota de libertad y de la posibilidad de trazar un camino real y verdadero de plenitud para, de este modo, dejar de caer en brazos del ciego azar del que no somos más que irónica expresión. En estaobra, se recoge página a página el amor por esa búsqueda interior de la que emanan todos nuestros anhelos más profundos: esa necesidad imperiosa de conectar con lo absoluto. (shrink)

Background: The research community has a mandate to discover effective treatments for neurodegenerative disorders. The ethics landscape surrounding this mandate is in a constant state of flux, and ongoing challenges place ever greater demands on investigators to be accountable to the public and to answer questions about the implications of their work for health care, society, and policy. Methods: We surveyed US-based investigators involved in neurodegenerative diseases research about how they value ethics-related issues, what motivates them to give consideration to (...) those issues, and the barriers to doing so. Using the NIH CRISP database we identified 1,034 researchers with relevant, active grants and invited them to complete an online questionnaire. We received 193 responses. We used exploratory factor analysis to transform individual survey questions into a smaller set of factors, and linear regression to understand the effect of key variables of interest on the factor scores. Results: Ethics-related issues clustered into two groups: research ethics and external influences. Heads of research groups viewed issues of research ethics to be more important than the other respondents. Concern about external influences was related to overall interest in ethics. Motivators clustered into five groups: ensuring public understanding, external forces, requirements, values, and press and public. Heads of research groups were more motivated to ensure public understanding of research than the other respondents. Barriers clustered into four groups: lack of resources, administrative burden, relevance to the research, and lack of interest. Perceived lack of ethics resources was a particular barrier for investigators working in drug discovery. Conclusions: The data suggest that senior level neuroscientists working in the field of neurodegeneration (ND), and drug discovery specifically, are motivated to consider ethics issues related to their work, but the perceived lack of ethics resources thwarts their efforts. With bioethics centres at more than 50% of the institutions at which these respondents reside, the neuroscience and bioethics communities appear to be disconnected. Dedicated ethical, legal and social implications (ELSI) programs, such as those fully integrated into genetics and regenerative medicine, provide models for achieving meaningful partnerships not yet adequately realized for scholars and trainees interested in drug discovery for ND.

In this article I explore some topics of the philosophy of law of Julius Binder. More specifically, I explore the relation and compatibility of his ideas with national-socialism. In the first part of the article I analyze the neo- Kantian approach underlying to his philosophy. Subsequently I analyze his turn towards neo- Hegelianism. In the last sections I address the philosophical concept of nation that this author defended and I search for its links with both national- socialism and Hegelian philosophy. (...) My final conclusion is that Hegel is not responsible for the use of his theories made by some Nazi authors such as Julius Binder. (shrink)

This book reports on theoretical and practical analyses of the ethical challenges connected to driving automation. It also aims at discussing issues that have arisen from the European Commission 2020 report “Ethics of Connected and Automated Vehicles. Recommendations on Road Safety, Privacy, Fairness, Explainability and Responsibility”. Gathering contributions by philosophers, social scientists, mechanical engineers, and UI designers, the book discusses key ethical concerns relating to responsibility and personal autonomy, privacy, safety, and cybersecurity, as well as explainability and human-machine interaction. On (...) the one hand, it examines these issues from a theoretical, normative point of view. On the other hand, it proposes practical strategies to face the most urgent ethical problems, showing how the integration of ethics and technology can be achieved through design practices. All in all, this book fosters a multidisciplinary approach where philosophy, ethics, and engineering are integrated, rather than just juxtaposed. It is meant to inform and inspire an audience of philosophers of technology, ethicists, engineers, developers, manufacturers, and regulators, among other interested readers. (shrink)

Millones de personas en el mundo no disponen de otra alternativa para huir de la pobreza más extrema que trabajar en condiciones de explotación en una sweatshop. A través de la non worseness-claim y el argumento de la elección, Powell y Zwolinski sostienen que, aunque dicha explotación sea moralmente problemática, proporciona beneficios a dichas personas que impediría considerarla gravemente injusta y justificar así la prohibición o regulación de las sweatshops. En este trabajo se analizan las claves de este discurso, así (...) como los principales intentos de rebatirlo basados en la idea de que dichas fábricas se aprovechan de injusticias de trasfondo de las que los empresarios son, de algún modo, responsables.

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.

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.

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)

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)
