Abduction is or subsumes a process of inference. It entertains possible hypotheses and it chooses hypotheses for further scrutiny. There is a large literature on various aspects of non-symbolic, subconscious abduction. There is also a very active research community working on the symbolic (logical) characterisation of abduction, which typically treats it as a form of hypothetico-deductive reasoning. In this paper we start to bridge the gap between the symbolic and sub-symbolic approaches to abduction. We are interested in benefiting from developments (...) made by each community. In particular, we are interested in the ability of non-symbolic systems (neural networks) to learn from experience using efficient algorithms and to perform massively parallel computations of alternative abductive explanations. At the same time, we would like to benefit from the rigour and semantic clarity of symbolic logic. We present two approaches to dealing with abduction in neural networks. One of them uses Connectionist Modal Logic and a translation of Horn clauses into modal clauses to come up with a neural network ensemble that computes abductive explanations in a top-down fashion. The other combines neural-symbolic systems and abductive logic programming and proposes a neural architecture which performs a more systematic, bottom-up computation of alternative abductive explanations. Both approaches employ standard neural network architectures which are already known to be highly effective in practical learning applications. Differently from previous work in the area, our aim is to promote the integration of reasoning and learning in a way that the neural network provides the machinery for cognitive computation, inductive learning and hypothetical reasoning, while logic provides the rigour and explanation capability to the systems, facilitating the interaction with the outside world. Although it is left as future work to determine whether the structure of one of the proposed approaches is more amenable to learning than the other, we hope to have contributed to the development of the area by approaching it from the perspective of symbolic and sub-symbolic integration.

This book explores why, regarding practical reasoning, humans are sometimes still faster than artificial intelligence systems. It is the first to offer a self-contained presentation of neural network models for many computer science logics.

Formal models of argumentation have been investigated in several areas, from multi-agent systems and artificial intelligence (AI) to decision making, philosophy and law. In artificial intelligence, logic-based models have been the standard for the representation of argumentative reasoning. More recently, the standard logic-based models have been shown equivalent to standard connectionist models. This has created a new line of research where (i) neural networks can be used as a parallel computational model for argumentation and (ii) neural networks can be used (...) to combine argumentation, quantitative reasoning and statistical learning. At the same time, non-standard logic models of argumentation started to emerge. In this paper, we propose a connectionist cognitive model of argumentation that accounts for both standard and non-standard forms of argumentation. The model is shown to be an adequate framework for dealing with standard and non-standard argumentation, including joint-attacks, argument support, ordered attacks, disjunctive attacks, meta-level attacks, self-defeating attacks, argument accrual and uncertainty. We show that the neural cognitive approach offers an adequate way of modelling all of these different aspects of argumentation. We have applied the framework to the modelling of a public prosecution charging decision as part of a real legal decision making case study containing many of the above aspects of argumentation. The results show that the model can be a useful tool in the analysis of legal decision making, including the analysis of what-if questions and the analysis of alternative conclusions. The approach opens up two new perspectives in the short-term: the use of neural networks for computing prevailing arguments efficiently through the propagation in parallel of neuronal activations, and the use of the same networks to evolve the structure of the argumentation network through learning (e.g. to learn the strength of arguments from data).

This paper studies methodologically robust options for giving logical contents to nodes in abstract argumentation networks. It defines a variety of notions of attack in terms of the logical contents of the nodes in a network. General properties of logics are refined both in the object level and in the metalevel to suit the needs of the application. The network-based system improves upon some of the attempts in the literature to define attacks in terms of defeasible proofs, the so-called rule-based (...) systems. We also provide a number of examples and consider a rigorous case study, which indicate that our system does not suffer from anomalies. We define consequence relations based on a notion of defeat, consider rationality postulates, and prove that one such consequence relation is consistent. (shrink)

This paper examines the role that linguistic and cognitive prominence play in the resolution of anaphor–antecedent relationships. In two experiments, we found that pronouns are immediately sensitive to the cognitive prominence of potential antecedents when other antecedent selection cues are uninformative. In experiment 1, results suggest that despite their theoretical dissimilarities, topic and contrastive focus both serve to enhance cognitive prominence. Results from experiment 2 suggest that the contrastive prosody appropriate for focus constructions may also play an important role in (...) enhancing cognitive prominence. Thus different types of linguistic prominence (topic, contrastive focus) appear to have the common effect of increasing the cognitive prominence of the discourse referent. For pronouns with two possible antecedents, the cognitive prominence of an antecedent aids in anaphor resolution, immediately biasing selection towards the more prominent (and ultimately preferred) antecedent.

Jednym z głównych problemów filozofii czasu jest określenie statusu teraźniejszości. Zagadnienie teraz pojawia się explicite choćby w dyskusji prezentyzm-eternalizm czy w pytaniu o możliwość uzgodnienia idei obiektywnego upływu czasu z rozumieniem czasu we współczesnej nauce. Filozofia nauki ujawnia zaś – wczeniej nie dostrzegany – problem zdefiniowania równoczesności.Dyskusje na temat obiektywności lub realności upływu czasu nie są domeną filozofii ostatniego stulecia ani też pokłosiem odkryć fizyki XX wieku. To właśnie jednak na gruncie fizyki nastąpiło spektakularne zderzenie intuicyjnego rozumienia czasu, w tym (...) tak oczywistych – zdawałoby się – idei, jak równoczesność czy współistnienie, z filozoficznymi implikacjami teorii naukowej. Rozbieżność intuicji temporalnych z czasem relatywistycznym analizowali pod kątem konsekwencji metafizycznych Gödel, Rietdijk i Putnam. Próby uzgodnienia klasycznych kategorii tensalnych z pojęciami STW, podejmowane m.in. przez Sklara, wskazują na konieczność wyeksplikowania odmiennych założeń ontologicznych obu schematów pojęciowych oraz potrzebę oddzielenia metafizyki od epistemologii. Radykalną propozycję wyeliminowania konfliktu między intuicją upływu czasu i relatywistycznym obrazem czasu wysunął Prior, który przypisał fundamentalną rolę potocznym kategoriom temporalnym (A-teoria), pojęcia relatywistyczne zaś uznał za czysto konwencjonalne i wtórne. Pogląd taki jawnie przeczyłby jednak ontologicznym założeniom STW, sformułowanym przez samego Einsteina.Niniejszy artykuł ma na celu wyeksplikowanie wspomnianych trudności w oparciu o fundamentalne założenia i własności klasycznej oraz relatywistycznej koncepcji czasu.

Artur Blaim’s Gazing in Useless Wonder. English Utopian Fictions 1516–1800, the thirteenth volume of the esteemed Ralahine Utopian Studies series, has already received praises as a must-read monograph from such renowned utopian scholars as Lyman Tower Sargent and Gregory Claeys—and indeed it challenges anyone who would dare state otherwise. And even though such flawless pieces of research are not that common, Blaim’s book definitely has the potential to set a precedent in that regard, being a thorough and cohesive analysis (...) of rather sporadically interpreted utopian texts and novels from even less often studied historical periods.Already the book’s composition reveals a direct association between the emergence of...

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

The embodied approach of human cognition suggests that concepts are deeply dependent upon and constrained by an agent's physical body's characteristics, such as performed body movements. In this study, we attempted to broaden previous research on emotional priming, investigating the interaction of emotions and visual exploration. We used the joystick-based approach-avoidance task to influence the emotional states of participants, and subsequently, we presented pictures of news web pages on a computer screen and measured participant's eye movements. As a result, the (...) number of fixations on images increased, the total dwell time increased, and the average saccade length from outside of the images toward the images decreased after the bodily congruent priming phase. The combination of these effects suggests increased attention to web pages' image content after the participants performed bodily congruent actions in the priming phase. Thus, congruent bodily interaction with images in the priming phase fosters visual interaction in the subsequent exploration phase. (shrink)

Der Aufsatz sich mit dem Problem der objektiven Gültigkeit der metaphysischen Erkenntnis in der Wolffschen "Ontologie". Besonders bin ich interessiert an der Problemstellung und Problemlösung, d.h. nicht nur am Begriff der transzendentalen Wahrheit, aber auch am Verhältnis zwischen ihm und dem Begriff der logischen Wahrheit und der Ordnung. Die Begriffe der transzendentalen Wahrheit und der Ordnung gehören zu wichtigsten Begriffen der Wolffschen Philosophie des Seins, die als die Grundlage allen anderen (philosophischen) Wissenschaften gedacht wird. Deshalb kann man sagen, dass der (...) Begriff der transzendentalen Wahrheit ist der echten Grundbegriff der ganzen Philosophie. In dem Aufsatz versuche ich zu zeigen, worin besteht die Wichtigkeit dieses Begriffes und mit ihm verbundenen Konzeption des Seins und der Erkenntnis. Der Aufsatz besteht aus drei Teilen: in der ersten beschäftige ich mich mit dem logischen Begriff der Wahrheit (nominale und reale Definition der Wahrheit), in der zweiten – mit dem Begriff der Ordnung (ordo), in der letzten – mit dem Begriff der transzendentalen Wahrheit.

We start by introducing the idea of echo chambers. Echo chambers are social and epistemic structures in which opinions, leanings, or beliefs about certain topics are amplified and reinforced due to repeated interactions within a closed system; that is, within a system that has a rather homogeneous sample of sources or people, which all share the same attitudes towards the topics in question. Echo chambers are a particularly dangerous phenomena because they prevent the critical assessment of sources and contents, thus (...) leading the people living within them to deliberately ignore or exclude opposing views. In the second part of this paper, we argue that the reason for the appearance of echo chambers lies in the adoption of what we call ‘epistemic vices’. We examine which vices might be responsible for their emergence, and in doing so, we focus on a specific one; ‘epistemic violence’. In assessing and evaluating the role of this epistemic vice, we note that it can be triggered by epistemic contexts characterized by high stakes that may turn ordinary intellectual virtues (such as skepticism) into vices (such as denialism). In the third part of this contribution, we suggest a way to deal with echo chambers. The solution focuses on advocating a responsibilist pedagogy of virtues and vices that -we claim- might be capable of preventing their emergence. (shrink)

Peter Achinstein has argued at length and on many occasions that the view according to which evidential support is defined in terms of probability-raising faces serious counterexamples and, hence, should be abandoned. Proponents of the positive probabilistic relevance view have remained unconvinced. The debate seems to be in a deadlock. This paper is an attempt to move the debate forward and revisit some of the central claims within this debate. My conclusion here will be that while Achinstein may be right (...) that his counterexamples undermine probabilistic relevance views of what it is for e to be evidence that h, there is still room for a defence of a related probabilistic view about an increase in being supported, according to which, if p > p, then h is more supported given e than it is without e. My argument relies crucially on an insight from recent work on the linguistics of gradable adjectives. (shrink)

Modern democracy is impossible without political parties. They are necessary in the process of the construction of the political class and building of relations between politicians and ‘ordinary people’. So, in Poland in the twentieth and the twenty-first centuries the significance of parties is also very important. Their history is older than the history of the reborn Poland. Especially in Galicia, an autonomous province of the Hapsburg empire, we can see the activities of many politicians. A part of them in (...) 1895 declared the birth of the Popular Party which is a constant element of the Polish political scene. The second traditional current is the socialistic movement, which is also always legally active in Poland. These two camps represent, in simplification, the ‘two Polands’—the first more traditional, conservative and provincial, and the second more progressive, ‘European’ and urban. Actually, in the typical consciousness of a Polish citizen, the political representation of the ‘black’ country is the party Law and Justice of Jarosław Kaczyński, and the ‘red’ country admires the Citizen Platform with Donald Tusk as a leader. But probably the idea of a twoparty system, like in the Anglo-Saxon world, is still very distant to reality, because in the European continent, the tradition of pluralism in a policentric version is still very significant. In Poland, even in the period of the ‘real socialism’ this conception of the organization of political life was realized, though naturally in the specific version. There were three legal parties and the Polish United Workers’ Party (the PUWP) was the most important. From 1976, the PUWP in the light of the Constitution had the official hegemony in the Republic. It is possible to compare this situation with the period 1926–39, when, after the coup d’état by Marshal Piłsudski, the Government still won in the election and the official elite wanted to create a stable political force with a perspective of permanent rule. But we must remember that between the wars opposition always was legal. In our times of demoliberalism, this is quite normal (though under the Constitution, unconstitutional parties, for example, communist or fascist, are unacceptable); however, interesting is the fact that when you observe sine ira et studio the evolutional trend of the Polish political system, you easily find the tendency of the ‘stabilization’ of the party system in the way of legal operations. From 1997, the laws concerning political parties have changed the possibilities of the conquest of seats in the Seym. Actually, only the parties having 5 per cent (or 8 per cent in coalition) of votes can gain the representation in the Diet. So it is possible to claim that the little parties today are in a more complicated situation than in the first years after the ‘operation of Round Table’ in 1989. The contemporary system is maybe more stable, but less liberal. There are theoreticians who note the danger of the alienation of the political class in the situation of the renewal of the alienation of the political elite, which de facto is more connected with the state than with the society. Many theoreticians emphasize that in the future the role and the character of political structures will be profoundly different from today. Maybe they are prophets, but we can expect that the Polish political parties or ‘post-parties’ and also political structure as a whole will have many similarities with their actual equivalents, because the mentality of the Polish nation, including the politicians, is more or less enduring.

This paper elaborates a new solution to the lottery paradox, according to which the paradox arises only when we lump together two distinct states of being confident that p under one general label of ‘belief that p’. The two-state conjecture is defended on the basis of some recent work on gradable adjectives. The conjecture is supported by independent considerations from the impossibility of constructing the lottery paradox both for risk-tolerating states such as being afraid, hoping or hypothesizing, and for risk-averse, (...) certainty-like states. The new proposal is compared to views within the increasingly popular debate opposing dualists to reductionists with respect to the relation between belief and degrees of belief. (shrink)

In recent years some archaeological commentators have suggested moving away from an exclusively anthropocentric view of social reality. These ideas endorse elevating objects to the same ontological level as humans – thus creating a symmetrical view of reality. However, this symmetry threatens to force us to abandon the human subject and theories of meaning. This article defends a different idea. It is argued here that an archaeology of the social, based on human intentionality, is possible, while maintaining an ontology that (...) does not involve dualistic conceptions of reality. Building upon the philosophical work of Vincent Descombes, it is contended that humans are intentional actors and society is predicated on triadic relations that involve humans, objects and meanings. These relations can only be understood holistically, given that these relations are merely parts of a meta-narrative. These meta-narratives contain specific historical and social settings, and it is only within these settings that social relations are intelligible. (shrink)

Para compreender as relações entre imagem e texto no livro moderno, é necessário ter em conta todos aqueles que contribuem para estabelecer os significados dos textos e das imagens. Falamos, assim, também de impressores e papeleiros que nos deixaram, como testemunho, as suas marcas.

Este artigo apresenta e comenta três dezenas de casos de utilização das armas portuguesas nas portadas de livros quatrocentistas e quinhentistas. Esta utilização enquadra-se no âmbito da heráldica tipográfica, com força expressiva equivalente à dos símbolos pessoais ou familiares, quase sempre porque editores, impressores ou livreiros entendiam que o escudo nacional dignificava sobremaneira o seu trabalho.

A aliança entre a Filologia e a História do Livro é indiscutível, do ponto de vista metodológico, e valiosíssima para a compreensão mesológica de qualquer edição, sendo certo que nenhum livro se publica sem estar inscrito numa dada moldura ecológica da cultura. Por isso mesmo, ultrapassando os limites próprios da actividade bibliográfica, o historiador do livro não pode prescindir da leitura dos textos que se escondem sob a opacidade do objecto livro.

‘We are before Dante’: In this interview, held via email in March 2020 amid the massive outbreak of the COVID-19 pandemic, Jean-Luc Nancy leads us on a brief but far-reaching foray through his thought. He succeeds in providing an overview of the subjects that he has raised since the beginning of his career as a philosopher, while maintaining a focus on their pertinence for what we are currently facing in the world today. He supplements his insight that ‘we are before (...) Dante’ with the equally remarkable conclusion: ‘Desire is what is born par excellence’. In between these two propositions, and in between the lines and words documented here – touching upon topics as diverse as the moai statues of Easter Island, the music of Schumann, Wagner, and techno, as well as the writing of Artaud, Proust, and Verlaine – we find an exciting, up-to-date treatment of the question of how to ‘deal with the world intellectually’ without, in doing so, participating in the modern claim to ‘master’ it. Instead, Nancy suggests, we ought to be attentive to what escapes us by its very principle, with philosophy, literature, and art serving as witnesses of what has always been absent from our mind, that is, the sensibility of meaning, in order to become aware that, since we are always already before and after birth, ‘we come from nowhere and everywhere’. This realization enables us to understand the political consequences that it has for our understanding of a world in metamorphosis, including for highly controversial issues such as colonialism, anti-Semitism, the far right, neo-liberalism, and other totalitarian forms that supposedly manifest a return of the myth, as well as its consequences for the insurmountability of Marx.

Початок повномасштабного російського вторгнення в 2022 році викликав значні зміни в українській національній ідентичності. Соціологічні опитування демонструють трансформацію цінностей та повсякденних практик українців. Вони почали частіше вживати українську мову, змінили історичні та конфесійні вподобання. Необхідним є отримання об’єктивного соціологічного знання стосовно причин та наслідків цих змін. Передумовою цього є дослідження існуючих робіт по даній тематиці. Метою статті є систематизація та критичне узагальнення наукових праць по тематиці української національної ідентичності у вітчизняній науці. Автор розглядає роботи по цій темі, написані дослідниками в (...) галузі різних наук: історії, філософії, політології, філології, соціології. Особливу увага приділяється огляду дисертацій. Узагальнюються основні ідеї праць, даються авторські висновки по можливості їх використання в майбутньому. Показується, що автори зачіпають широке коло питань, що стосуються національної ідентичності: її історична ґенеза, трансформації, фактори мови та історичної пам’яті, відображення ідентичності в мистецтві та медіа, вплив на неї глобалізації та російської агресії. Автор констатує, що дана проблематика поки що слабо розвинута в рамках соціологічної науки. У відкритому доступі відсутні значні теоретичні роботи, здебільшого соціологи займаються виключно емпіричними дослідженнями. Також відсутні теоретичні роботи, присвячені аналізу трансформацій національної ідентичності, що стались з початку повномасштабної російської агресії в лютому 2022 році. Це пояснюється недостатнім проміжком часу, що пройшов на даний момент. Також складності додає швидка зміна політичних та військових реалій. Враховуючи значну суспільну значимість, автор робить висновок про необхідність посилення соціологічного осмислення цієї тематики. (shrink)

In a recent publication Travis Timmerman has claimed that sometimes it is morally permissible to not prevent something bad from happening, even if it is in one’s power to do so without sacrificing anything nearly as important.1 To defend his point, he has proposed a thought experiment and based his claims on putative common-sense morality intuitions. To aid in the subsequent discussion, Timmerman’s case is reproduced as follows.

Humans are often extraordinary at performing practical reasoning. There are cases where the human computer, slow as it is, is faster than any artificial intelligence system. Are we faster because of the way we perceive knowledge as opposed to the way we represent it? -/- The authors address this question by presenting neural network models that integrate the two most fundamental phenomena of cognition: our ability to learn from experience, and our ability to reason from what has been learned. This (...) book is the first to offer a self-contained presentation of neural network models for a number of computer science logics, including modal, temporal, and epistemic logics. By using a graphical presentation, it explains neural networks through a sound neural-symbolic integration methodology, and it focuses on the benefits of integrating effective robust learning with expressive reasoning capabilities. -/- The book will be invaluable reading for academic researchers, graduate students, and senior undergraduates in computer science, artificial intelligence, machine learning, cognitive science and engineering. It will also be of interest to computational logicians, and professional specialists on applications of cognitive, hybrid and artificial intelligence systems. (shrink)
