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)

§1. Mathematics and the physical world. Genuine scientific knowledge cannot be certain, nor can it be justified a priori. Instead, it must be conjectured, and then tested by experiment, and this requires it to be expressed in a language appropriate for making precise, empirically testable predictions. That language is mathematics.This in turn constitutes a statement about what the physical world must be like if science, thus conceived, is to be possible. As Galileo put it, “the universe is written in the (...) language of mathematics”. Galileo's introduction of mathematically formulated, testable theories into physics marked the transition from the Aristotelian conception of physics, resting on supposedly necessary a priori principles, to its modern status as a theoretical, conjectural and empirical science. Instead of seeking an infallible universal mathematical design, Galilean science usesmathematics to express quantitative descriptions of an objective physical reality. Thus mathematics became the language in which we express our knowledge of the physical world — a language that is not only extraordinarily powerful and precise, but also effective in practice. Eugene Wigner referred to “the unreasonable effectiveness of mathematics in the physical sciences”. But is this effectiveness really unreasonable or miraculous?Numbers, sets, groups and algebras have an autonomous reality quite independent of what the laws of physics decree, and the properties of these mathematical structures can be just as objective as Plato believed they were.

Quantum computers use the quantum interference of different computational paths to enhance correct outcomes and suppress erroneous outcomes of computations. In effect, they follow the same logical paradigm as (multi-particle) interferometers. We show how most known quantum algorithms for factorising and counting, may be cast in this manner. Quantum searching is described as inducing a desired relative phase between two eigenvectors to yield constructive interference on the sought elements and destructive interference on the remaining terms.

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)

As the title of the present publication suggests, the ten essays of this book try to approach an inconvenient trauma of global human reality and the uniformity of media and cyberspace in which human lives suffer harm, loss of inner identity and of broader meaning. Indeed, our postmodern and post-identity times are characterized by a flux of rapid social changes, uncertainty, vague and shaking moral values, by violence and frightening information with its contradictory truths and genuine ambiguity; finally by the (...) violence of unpredictable climate change resulting in various and frequent calamities and devastation of life. Doubt and time are the central concern of modern philosophy and remind us that violence is inherent in the human condition and that reflection on it, regardless of different cultural sensibilities, is ipso facto part of the mainstream of our individual and global concerns. These, and many other fascinating topics from Western and Chinese history, were explored and brought to light by a learned forum of distinguished scholars and experts whose contributions are contained in this publication.

Joshua Crites and Eric Kodish focuses on unrealistic optimism as a significant factor in parental decisions when consenting for their child to participate in a phase I study.1 They define unrealistic optimism as ‘when people perceive their own personal outcomes as being more positive than those of other people in similar circumstances’. Faced with the dire circumstances of relapsed malignant disease with a fatal outcome, most parents are confronted with the dilemma of either accepting the inevitable death of their child (...) or clinging to straws of hope. When approached by an investigator who suggests that there is still something that can be done in the ‘fight against the disease’ there is an opportunity to retain a glimmer of hope.

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)

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)

The aim of this paper is to show that it is the explicativecharacter of Tarski's semantic definition of truth given in his study of 1933 that allows forconsideration of a philosophical background of this definition in the proper sense. Given the explicativecharacter of this definition it is argued that the philosophical tradition that should be taken intoaccount with regard to this philosophical background is the tradition of the Lvov-Warsaw Schoolin its connections with the School of Brentano. As an example of (...) the explanatory power ofconsidering this tradition as far as Tarski's philosophical choices are concerned I use here thenotion of sentence-inscription, i.e., the notion of that entity of which truth is predicated inthe definition in question. One of the consequences of these statements is that philosophicaldiscussions concerning the semantic definition of truth can be regarded from two points ofview. On the one hand, they may take the perspective of its explicational function, i.e., theperspective of its philosophical background. On the other hand, they might consider the philosophicalconsequences of the definition with respect to the goal of the explication, i.e., they may considerits philosophical content independently of its historical background.

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)

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.

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.

O presente artigo tem como pretensão oferecer um olhar outro acerca da depressão. Nossa análise sobre tal fenômeno encontra na filosofia, sobretudo, de Byung-Chul Han, uma possibilidade interessante de ir além das explicações psiquiátricas. Entretanto, são nelas que esse texto inicia sua discussão: a hipótese serotoninérgica da depressão é apresentada, mas também, problematizada, pois, muito embora a psiquiatria encontre nela ainda hoje a sua tese nuclear acerca do comportamento depressivo, é mostrado aqui que, além de ser uma teoria ausente de (...) comprovação científica, também carece de consistência para explicar o avanço da depressão ao redor do mundo. É diante da impossibilidade de pensar a depressão biologicamente que, no segundo momento deste artigo, há um esforço para analisar os modos de estruturação social contemporâneos, baseados na positivação da sociedade e na busca desenfreada por desempenho, e buscar nos mesmos, fatores desencadeantes do comportamento depressivo. A última parte do texto se concentra em apresentar um panorama filosófico centrado nas perspectivas de Han acerca da depressão. Através da exposição do mito de Eros e Psique, o artigo encerra sua análise mostrando a influência que o desaparecimento do Outro e a pressão por desempenho exerce na formação de uma sociedade de pessoas depressivas.

The topic of this paper I would like to divide into two other questions than that of its title. The first question is the historical one and sounds like this: Why had Tarski chosen physical objects as truth-bearers in his original work from 1933 about truth in formalized languages?1 This historical problem may be still of importance not only from a historical point of view. Tarski’s truth-definition is still seen as one of undeniable importance for any contemporary philosophical analysis of (...) truth. (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)

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.

According to the good reasoning view of normative reasons, p is a reason to F, just in case p is a premise of a good pattern of reasoning. This article presents two counterexamples to the most promising version of the good reasoning view.

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)

The idea of cognitive enhancement refers to multifaceted and interdisciplinary approach aimed at improving human mental processes. Cognitive enhancement is the amplification or extension of core mind capacities through improvement or augmentation of either internal or external information processing systems. This includes improvements of intelligence and attention, reinforcement of creativity and memory, or extension of perception range. The main feature of cognitive enhancement is voluntariness of use for overcoming natural mental limitations. This article is a synthesis of current trends in (...) cognitive enhancement from the perspective of transhumanism. The article presents various definitions of cognitive enhancement, methods of cognitive enhancement as well as challenges and questions concerning improving human mental processes. (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)

The northern creative trips of the People's Artist of the USSR Vladimir Alexandrovich Igoshev (1921-2007) represent important and vivid pages in his creative biography. The object of this research is the creative heritage of the artist V.A. Igoshev. The subject of the study is the creative trips of the artist V.A. Igoshev to the North (Sverdlovsk and Tyumen regions) of the 1950s and 1960s. The purpose of this study is to reconstruct the overall picture of the northern creative trips of (...) the artist V.A. Igoshev of the 1950s–1960s on the basis of paintings and graphic works of the early "northern cycle", archival materials, exhibition catalogues, Soviet periodicals, individual scientific articles and information from informants. The novelty of the research lies in the most complete and detailed consideration at the moment of the issue of the northern creative trips of the artist V.A. Igoshev in the 1950s and 1960s. Previously, this topic has not received special coverage. Modern researchers of the creative heritage of the artist V.A. Igoshev in their review articles practically did not touch on this problem, limiting themselves to mentioning individual episodes from the creative biography of the master. The author of the study provides historical facts related to specific dates of trips, introduces a list of paintings and graphic works, with all the circumstances of their creation and further exposure at major art exhibitions of the 1950s and 1960s.

This paper explores one way in which the view that emotions can be epistemically justified stands in tension with two common views in epistemology; namely, that doxastic justification entails propositional justification, and that propositional justification is entirely determined by the (inferential) support relations between one's evidence and a given proposition. A tentative solution to the tension is provided.

In this paper, I argue against recent versions of justification norms of action and practical deliberation . I demonstrate that these norms yield unacceptable results in deception cases. However, a further modification of justification norms in the light of these results appears to be ad hoc. Hence, I claim, we should reject justification norms of action and practical deliberation.

By all accounts, virtue epistemology is making a value turn in contemporary analytic epistemology. In this article, this twist is explicated through the transformation of the understanding of epistemic values and the value of the epistemic. In the first sense, we are talking about how the view has changed on what determines the epistemic value of such categories as truth, knowledge, understanding, etc. In the second sense, we are talking about the value of our epistemic concepts (the value of the (...) epistemic): what is true belief, knowledge, etc. for? It is shown how the causal link between our beliefs and intellectual virtues allows us to explain the nature and value of knowledge as a central category of epistemology. The author reveals the difference between the main types of virtue epistemology through the prism of two different approaches to the justification of values: value internalism and value externalism. Value externalism assumes that a state/motive/action gains value from something outside of a person's consciousness. In contrast, value internalism holds that the conditions that determine value are internal to consciousness. For reliabilism, the value of cognitive success lies in its causal connection with the reliable competences of the subject, for responsibilism – with virtuous motives of cognitive activity. Common to reliabilism and responsibilism is that they shift the focus from the value of an effect (truth) to its relationship with the value of a cause – an ability or excellent trait of intellectual character. The main approaches to substantiating the fundamental value of knowledge in virtue epistemology are analyzed. If for reliabilism the highest epistemic value is truth as cognitive achievement, then for responsibilism the value of epistemic categories is primarily in their moral significance – the achievement of a good life and happiness (eudaimonia). In conclusion, the problematic aspects of virtue epistemology are formulated and promising directions for its further development are shown. (shrink)

The paper analyzes the strategy of refuting skepticism by virtue epistemology of Ernest Sosa. Responses to skeptical challenge are overviewed. The philosophical and meta-philosophical strategies are outlined. The solution based on distinguishing between reflective knowledge and animal knowledge is considered. The internalist assumptions of skepticism are critically exposed. The notion of web of belief is further used to support an anti-skeptical position. Shane Ryan’s notion of epistemic grace is put forward in defense of the virtue epistemology approach.
