The question I consider is this: -/- The Question: Can two people–who are, and realize they are, intellectually virtuous to about the same degree–both be rational in continuing knowingly to disagree after full disclosure (by each to the other of all the relevant evidence they can think of) while at the same time thinking that the other may well be rational too? -/- I distinguish two kinds of rationality–internal and external–and argue in section 1 that, whichever kind we have in (...) mind, the answer to The Question is ‘yes’ (though that positive answer is less wholehearted in the case of external rationality). Then, in section 2, I briefly make some more general remarks about when discovering a disagreement provides a defeater and when it doesn't. In the final section, I consider an important objection to the answer given in section 1 to The Question. (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.

This outstanding book is a leading text for symbolic or formal logic courses. All techniques and concepts are presented with clear, comprehensive explanations and numerous, carefully constructed examples. Its flexible organization (all chapters are complete and self-contained) allows instructors the freedom to cover the topics they want in the order they choose.

Predication is an indisputable part of our linguistic behavior. By contrast, the metaphysics of predication has been a matter of dispute ever since antiquity. According to Plato—or at least Platonism, the view that goes by Plato’s name in contemporary philosophy—the truths expressed by predications such as “Socrates is wise” are true because there is a subject of predication (e.g., Socrates), there is an abstract property or universal (e.g., wisdom), and the subject exemplifies the property.1 This view is supposed to be (...) general, applying to all predications, whether the subject of predication is a person, a planet, or a property.2 Despite the controversy surrounding the metaphysics of predication, many theistic philosophers—including the majority of contemporary analytic theists—regard Platonism as extremely attractive. At the same time, however, such philosophers are also commonly attracted to a form of traditional theism that has at its core the thesis that God is an absolutely independent.. (shrink)

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)

Professor Merrie Bergmann presents an accessible introduction to the subject of many-valued and fuzzy logic designed for use on undergraduate and graduate courses in non-classical logic. Bergmann discusses the philosophical issues that give rise to fuzzy logic - problems arising from vague language - and returns to those issues as logical systems are presented. For historical and pedagogical reasons, three-valued logical systems are presented as useful intermediate systems for studying the principles and theory behind fuzzy logic. The major (...) fuzzy logical systems - Lukasiewicz, Gödel, and product logics - are then presented as generalisations of three-valued systems that successfully address the problems of vagueness. A clear presentation of technical concepts, this book includes exercises throughout the text that pose straightforward problems, that ask students to continue proofs begun in the text, and that engage students in the comparison of logical systems.

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. Duas diferentes vias nos levam, através da análise da imagem, aos impressores e ao seu trabalho: por um lado, o conhecimento da principal matéria-prima, o papel, com as suas marcas de água e filigranas, e, por out...

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.

According to a widely held view epistemic justification is a normative notion. According to another widely held assumption, epistemic justification comes in degrees. Given that gradability requires a context-sensitivity that normativity seems to lack, these two assumptions stand in tension. Giving up the assumption of gradability of justification represents a lesser theoretical cost.

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)

Internalists tend to impose on justification higher-level requirements, according to which a belief is justified only if the subject has a higher-level belief (i.e., a belief about the epistemic credentials of a belief). I offer an error theory that explains the appeal of this requirement: analytically, a belief is not justified if we have a defeater for it, but contingently, it is often the case that to avoid having defeaters, our beliefs must satisfy a higher-level requirement. I respond to the (...) objection that externalists who endorse this error theory will be forced to accept a radical form of scepticism. (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.

At a purely instrumental level, quantum theory is all about multiplication, addition and taking mod squares of complex numbers called probability amplitudes. The rules for combining amplitudes are deceptively simple. When two or more events are independent you multiply their respective probability amplitudes and when they are mutually exclusive you add them. Whenever you want to calculate probabilities you take mod squares of respective amplitudes. That’s it. If you are prepared to ignore the explanatory power of the theory (which you (...) should not) the rest is just a set of convenient mathematical tools developed for the purpose of book-keeping of amplitudes. Thus we tabulate amplitudes into state vectors and unitary matrices, and place them in Hilbert spaces. (shrink)

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)

In this article I focus on some unduly neglected common-sense considerations supporting the view that one's evidence is the propositions that one knows. I reply to two recent objections to these considerations.

Diese Betrachtungen versuchen das Problem der intellektuellen Intuition bei R. Descartes anhand der Abhandlung "Die Regeln zur Leitung des Verstandes" vorzustellen. Die Intuition der Gemüt (intuistus mentis) ist eine eigentümliche Fähigkeit der menschliechen Vernunft, kraft dessen nicht nur direkte Erkenntnis der obersten Prinzipen, aber auch jede unsere gültige Erkenntnis möglich ist. Deshalb ist die Intuition der Gemüt (als ein Erkenntnisvermögen des Subjekts) notwendig, um eine Konzeption der Intuition (die Methode) zu entwickeln. Das aber, was unbedingter Grund (Principium) und zugleich die (...) Bedinung der Möglichkeit jeder unserer unmittelbaren Erkenntnis ist, kann nicht direkt erkannt werden. Dem die Methode kann nicht ein unbedingtes Wissen um Intuition sein, und ausserdem ist ihre Gültigkeit problematisch. Darum betreffen diese Überlegungen vor allem das Problem der Gültigkeit der kartesianischen Konzeption der intellektuellen Intuition. Die Methode kann nur erklären wie die Intuition (und Deduktion) richtig gehandhabt wird. Aber sie kann nicht lehren, wie diese Operationen vollgezogen werden. Die Fragestellung lautet nun: wie die Intuition zu erkennen sei? (shrink)

Die Begriffe "Erscheinung" und "Ding an sich" wurden im Laufe der Zeit vielmals interpretiert und wohl so oft mißinterpretiert. Der Hauptgrund der falschen Interpretationen von den obiegen Begriffen scheint ihr platonischer oder eher von Plato inspirierter Charakter za sein. Darunter verstehe ich eine solche Auslegung der Beziehung "Erscheinung" – "Ding an sich", in der sie als der Schein und die reale Wirklichkeit im Gegensatz zueinander stehen. Zu den wichtigsten und gleichzeitig konfusesten Texten von Kant, die er dem Problem gewidmet hat, (...) gehört der Kapitel von der "Kritik der reinen Vernunft": "Phaenomena und Noumena". Meine Arbeit ist ein solcher Analyse – und Interpretationsversuch von diesem Fragment, der einerseits den für die beiden Redaktionen (von der A und B Kritikausgabe) gemeinsamen und gleichzeitig den fundamentalen Sinn der Kantschen Lehre über "Erscheinung" und "Ding an sich" hervorhebt und vorstellt, andrereseits andere von Plato inspiriete Auffassungen dieses Problems als unberechtigt ablehnt.

Archaeology and Intentionality explores perhaps one of the most overlooked topics in archaeology, that of intentionality. In archaeology, most explanations of human behaviour rely on intentionality and this book fills a surprising gap in the literature. By identifying the historical trajectory of the notion of intentionality, this book reframes our understanding of what it means to act intentionally and how archaeologists provide explanations concerning past (and present) societies. In general, this book presents a strong framework for archaeological research, one that (...) fits to current archaeological practices and research around the world. This framework considers that past actors were not unconditional free agents, who could act however they wished, nor were they absolute prisoners of the economic, biological, and environmental circumstances in which they lived. From the standpoint of intentionality, it becomes clear that human agency is not about what you can or cannot do, but about what you should, that is to say, actions are above all ethical. In a world wealth inequality runs rampant, where humans have damaged the environment beyond recognition, and where technology advances at an alarming rate - it is important that we recognize our intentions and the ethical responsibility that accompanies those intentions. The book highlights how archaeology is the perfect discipline to understand how and from where those intentions come from. Addressing several problems in archaeological theory and connecting archaeology, philosophy and social theory, this book. (shrink)

Archaeology is currently bound to a series of metaphysical principles, one of which claims that reality is composed of a series of discrete objects. These discrete objects are fundamental metaphysical entities in archaeological science and posthumanist/new Materialist approaches and can be posited, assembled, counted, and consequently included in quantitative models (e.g. Big Data, Bayesian models) or network models (e.g. Actor-Network Theory). The work by Sørensen and Marila shows that archaeological reality is not that discrete, that some objects cannot be easily (...) identified, and that perhaps reality is not always necessarily composed of discrete objects. The aim of this article is to take Sørensen and Marila’s arguments to their ultimate logical consequences: most archaeological theory today operates under the illusion of a general metaphysics. This illusion dictates not only that all of reality is composed of discrete objects, but that since reality manifests in a certain way, there has to be a methodology that accurately represents that reality. A brief discussion on the notion of “conjecture,” as conceived in certain historical theories, is also presented. (shrink)
