Apresenta-se uma síntese do estudo comparativo das classificações de Ernst Mach, Rudolf Carnap e Hans Reichenbach, com um objetivo principal: a demarcação do problema geral – “o que é espaço?” – em prol da delimitação do problema específico: “o que é espaço físico?” Para isso, é necessário contrastar tal conceito com os demais “tipos de espaço” que designam os diferentes significados que a palavra ‘espaço’ pode assumir; significados estes restritos à interseção das áreas da física, da matemática e da filosofia. (...) Mach classificava “o espaço” em três tipos por considerar três vias de abordagens distintas: o espaço fisiológico (visual, tátil), os espaços geométricos (euclidiano, não euclidianos) e o espaço métrico (no sentido de “espaço das experiências métricas físicas”). Carnap, na sua tese doutoral “Der Raum”, defendeu uma classificação ternária diferente, na qual não há um “espaço” unificador, há três tipos que devem ser rigorosamente distinguidos, embora preservem relações: o espaço formal, o espaço intuitivo e o espaço físico. Por fim, Reichenbach, na sua magna obra “The Philosophy of Space & Time”, atacou todas as tentativas de classificações ternárias e as reduziu à dual distinção entre espaço físico e espaços matemáticos. Por que esta distinção radical é “tão atual”? Ela superou as demais? (shrink)

From the outside, our senses are spatially integrated in our body in manifestly different ways. This paper starts from the suggestion that the philosophical formulation of the problem of spatial perception, as it flows from the modern opposition of mind and world, is partly responsible for the fact that philosophers have often explicitly disregarded the spatial nature of the senses themselves. An indirect consequence is that much philosophical work focuses on how the senses can – or cannot – perceive the (...) same spatial features of objects in the same way, while disregarding the massive differences in performance among the senses. This paper explores the ways in which the spatial integration of our senses determines what each of our senses excels in, and hence what they contribute to our spatial relation to a physical environment. By juxtaposing descriptive analyses of a variety of selected cases, the paper gives priority to how various aspects of the world appear to us in order to obtain insight into the meaning of spatiality for different senses.

In Liberating Oedipus?: Psychoanalysis as Critical Theory, Dr. Filip Kovacevic demonstrates how psychoanalytic theory can join political theory in designing alternative political norms and values. Kovacevic proves that political practice without an emancipatory psychology to guide it is potentially dangerous.

Neste artigo, defenderei que o recurso à imagem de Giges que é feita por Glauco no livro II da República de Platão serve ao propósito de demonstrar que, dada a ambição (πλεονεξία) que é própria à natureza humana, a concessão de um poder ilimitado a quem quer que seja conduz fatalmente à tirania. Antes disso, contudo, reconstruirei a hipótese de Glauco para a origem da justiça e por fim sustentarei como Glauco, ao final do seu discurso, procura superar o plano (...) alegórico do relato que ele faz de Giges, sem, por outro lado, renunciar aos princípios que ali são postulados. Com isso, pretendo também mostrar que o discurso de Glauco constitui uma unidade minimamente consistente. Palavras-chave: Glauco; Giges; Técnica; Tirania. Glaucon’s speech and the birth of the tyrant in Republic II Abstract: In this article, I argue that Glaucon's use of the image of Gyges in Book II of Plato's Republic is intended to demonstrate that, given the human tendency towards ambition (πλεονεξία), the granting of unlimited power to anyone inevitably leads to tyranny. Before that, I first explain Glaucon’s hypothesis for the origin of justice. Then, I maintain how Glaucon attempts to go beyond the allegorical level of the Gyges story in his speech's conclusion, while still holding onto the principles presented therein. Through this, I aim to demonstrate that Glaucon's speech is a consistent unit. Key-words: Glaucon; Gyges; Skill; Tyranny. Le discour de Glaucon et la naissance du tyrant dans le livre II de la République Résumé: Dans cet article, je soutiendrai que l'utilisation de l'image de Gygès par Glaucon dans le Livre II de La République de Platon vise à démontrer que, compte tenu de la tendance humaine à l'ambition (πλεονεξία), l'octroi d'un pouvoir illimité à quiconque conduit inévitablement à la tyrannie. Avant cela, j'expliquerai d'abord l'hypothèse de Glaucon sur l'origine de la justice. Ensuite, je maintiendrai comment Glaucon cherche à dépasser le niveau allégorique de l'histoire de Gygès dans la conclusion de son discours, tout en conservant les principes présentés dans celui-ci. Ainsi, je vise à démontrer que le discours de Glaucon constitue une unité cohérente. Mots-clés: Glaucon; Gygès; Expertise; Tyrannie. Data de registro: 01/08/2023 Data de aceite: 22/11/2023. (shrink)

The nature of unconscious information processing is a heavily debated issue in cognitive science , and neuroscience . Traditionally, it has been thought that unconscious cognitive processing is restricted to knowledge that is strongly prepared by conscious processes . In three experiments, we show that the task that is performed consciously can also be applied unconsciously to items outside the current task set. We found that a same–different judgment of two target stimuli was also performed on two subliminally presented prime (...) stimuli. This was true for target and prime stimuli from entirely different categories, as well as for prime and target stimuli at different levels of abstraction. These results reveal that unconscious processing can generalize more widely than previously accepted. (shrink)

Contemporary theories of institutions as clusters of stable solutions to recurrent coordination problems can illuminate and explain some unresolved difficulties and problems adhering to institutional definitions of art initiated by George Dickie and Arthur Danto. Their account of what confers upon objects their institutional character does not fit well with current work on institutions and social ontology. The claim that “the artworld” confers the status of “art” onto objects remains utterly mysterious. The “artworld” is a generic notion that designates a (...) sphere of human activity that involves practices that create goals that have led to the emergence of formal and informal institutions. But those institutions, rather than magically “creating” objects subjected to esthetic appreciation, merely solve familiar and ubiquitous coordination problems created by artistic activity in ways other institutions in other areas solve similar and/or analogous coordination problems.

This paper focuses on the links between Jakob von Uexküll’s theoretical biology and Adolf Portmann’s conception of organic life. Its main purpose is to show that Uexküll and Portmann not only share a view of the living being as an autonomous and holistically organized entity, but also base this view on the seminal idea of the subjectivity of the organism. In other words, the respective holistic principles securing the autonomy of the living being—the Bauplan, for Uexküll; the Innerlichkeit, for Portmann—share (...) an essentially subjective character. Such principles, indeed, express themselves in a centrally directed and formative way; moreover, in organisms endowed with a central nervous system, they also extend their influence on the overt behavioral sphere and on the organism’s capacity to give meaning to the surrounding reality. The conclusion of the article will show how, though starting from this common background, the two authors develop divergent positions on the issue of the anthropological difference. If Portmann emphasizes the special status of the relationship between the human animal and the world, Uexküll tends to see a substantial continuity in the biosemiotic processes through which human and non-human animals constitute their species-specific worlds of experience.

This book is the first anthology to provide a wide-ranging picture of how phenomenology relates to language.

The aim of this article is to clarify the meaning of a naturalistic position within philosophy of biology, against the background of an alternative view, founded on the basic insights of transcendental philosophy. It is argued that the apparently minimal and neutral constraints naturalism imposes on philosophy of science turn out to involve a quite heavily constraining metaphysics, due to the naturalism’s fundamental neglect of its own perspective. Because of its intrinsic sensitivity to perspectivity and historicity, transcendental philosophy can avoid (...) this type of hidden metaphysics. (shrink)

This paper addresses several objections that have been leveled against a behavioral approach to psychological categories. It reconstructs and critically assesses the so-called causal objection; alleged counterexamples whereby one can exhibit the typical behaviors associated with a psychological phenomenon without exhibiting the latter, including Lewis’ “perfect actor” case and Kirk’s “zombie”; alleged counterexamples whereby organisms can exemplify psychological phenomena without exhibiting any behavior associated with them, including Armstrong’s imagined brain in a vat, Putnam’s “super-super-spartans” scenario, and related cases; and the (...) holistic objection. Mistaken assumptions in each of these objections are pinpointed. The paper starts with a brief characterization of behaviorism about psychological categories and a summary of the particular version thereof supported here, which draws upon Ryle and Skinner, among others.

In this paper we examine interactions of the reciprocal with distributive and collective operators, which are encoded by prefixes on verbs expressing the reciprocal relation: namely, the Czech distributive po and the collectivizing na-. The theoretical import of this study is two-fold. First, it contributes to our knowledge of how word-internal operators interact with phrasal syntax/semantics. Second, the prefixes po and na generate (a range of) readings of reciprocal sentences for which the Strongest Meaning Hypothesis (SMH) proposed by Dalrymple et (...) al. (1998) does not make the right predictions. The distributive prefix po prefers the Strong Reciprocity reading, although the SMH predicts that a weakening should take place, while with the prefix na we find cases where weaker reciprocal readings are preferable to the stronger ones predicted by the SMH. This behavior of po and na is, we propose, due to the way in which they modulate two factors that are crucial in the interpretation of reciprocal sentences: (i) the relevant subpluralities in the group denoted by the reciprocal's antecedent, and (ii) the strength of reciprocal relations. We provide a detailed analysis of the semantics of the prefixes po and na and their contribution to the meaning of reciprocal sentences within the general framework of event semantics with lattice structures.

ABSTRACT By turning his focus to individuals – the profile of billionaires as the people they are – Peter Hägel offers in his book Billionaires in World Politics an interesting move towards agency, showing that their power, even if situated in a complex economic structure, also consists in bending, changing, or setting the rules of how the game is played. After having followed the move of the pendulum from structure to agency with Hägel, in this paper I suggest that moving (...) back to structural analyses could again provide new insights. I argue that in order to have a more complete picture of the billionaires-and-politics puzzle, it is required to not only look at agency as a kind of reflexive phenomenon, but also to provide a more historically informed genealogy of the conditions under which billionaires’ passions have been shaped.

ABSTRACTResearch has established that human thinking is often biased by intuitive judgement. The base-rate neglect effect provides such an example, so named because people often support their decisions in stereotypical individuating information, neglecting base-rates. Here, we test the hypothesis that reasoners acknowledge information provided by base-rates and may use individuating information in support of a “rational” decision process. Results from four experiments show that “base-rate neglecting” occurs when participants acknowledge sample distributions; participants who prefer individuating over base-rate information perceive base-rates (...) as less diagnostic and are more confident in their individuating-based responses; and that posterior probabilities predict more individuating-based responses for individuating-preference participants. However, data also show a deeper form of base-rate neglect: even when some partic... (shrink)

The article tries to show that Aristotle's refutation of causal determinism in Metaph. 6.3 is grounded mainly on two assumptions: a. that there must be a first member of any causal chain, and b. that the origin and the outcome of the chain have to be of equal status.

Because philosophical reflections on touch usually start from our ability to perceive properties of objects, they tend to overlook features of touch that are crucial to correct understanding of tactual perception. This paper brings out these features and uses them to develop a general reconception of the sense of touch. I start by taking a fresh look at our ability to feel, in order to reveal its vital role. This sheds a different light on the skin's perceptual potential. While it (...) is commonly observed that tactile experiences have two intentional objects, an external object and one's own body, I will advance a more accurate alternative: in tactile experiences, one becomes aware of what one's body undergoes. This alternative not only fits better with tactility's vital role; it is also key to explaining how active touching provides for a unique contribution to our perceptual relation to material objects. By thus connecting tactility's vital role to the way we rely on touch while manipulating objects, this essay offers a cross-sectional survey of our tactile powers that reveals the interplay between sensing and touching.

V dějinách filozofie se objevilo nespočetné množství snah překonat kognitivní nedostatečnost člověka. Většinový názor zněl, že zatímco vnější smyslové poznání podléhá nejrůznějším klamům, poznání vnitřní je mnohem jistější, či dokonce neomylné. Předpokládaná znalost sebe sama je ovšem iluzorní a stala se důvodem pro vznik mnoha chybných přístupů ke skutečnosti. Kniha se skládá ze tří částí. První kapitola se zabývá introspekcí, především jejím přijetím v dějinách filozofie a odmítnutím v psychologickém behaviorismu 20. století. Druhá kapitola pojednává o iluzornosti svobody rozhodování, která (...) je způsobena řadou nevědomých mechanismů, o jejichž fungování máme zatím jen dosti matnou představu. Ve třetí kapitole jsou domýšleny důsledky kauzálního determinismu pro etiku a právo, především ve smyslu odmítnutí koncepcí morální odpovědnosti a retributivní spravedlnosti. Autor se tak pokouší dokázat, že podstatná část názorů zdravého rozumu je chybná a měla by být nahrazena sadou nových, kompatibilních s dnešní vědou. (shrink)

The demarcation of pseudoscience has been one of the most important philosophical tasks since the 1960s. During the 1980s, an atmosphere of defeatism started to spread among philosophers of science, some of them claimed the failure of the demarcation project. I defend that the more auspicious approach to the problem might be through the intellectual character of epistemic agents, i.e., from the point of view of vice epistemology. Unfortunately, common lists of undesirable character features are usually based on a priori (...) reasoning, and therefore might be considered artificial or too vague. When we base our position on contemporary behavioural sciences, we can see that the epistemic character of believers in pseudoscience is for the most part determined by two related factors. Firstly, these epistemic agents show a higher level of cognitive laziness. By this I mean an inability or unwillingness to engage in reflective thinking and a reluctance to account for counterevidence. Secondly, they yield more easily to metacognitive overconfidence. This can be broadly understood as so-called “knowledge illusion”, the inability to recognize one’s own intellectual limits. The deficiency usually stems from a misunderstanding of the division of cognitive labour and of the agent’s role in epistemic society. I find the proposed epistemological approach to pseudoscience crucial. Only if we understand the descriptive aspects of the problem, can we think of normative solutions to it. (shrink)

The relationship of humans to other primates – both in terms of abilities and evolution - has been an age-old topic of dispute in science. In this paper the claim is made that the different views of authors are based not so much on differences in empirical evidence, but on the ontological stances of the authors and the underlying ground narratives that they use. For comparing and reconciling the views presented by the representatives of, inter alia, cognitive ethology, comparative psychology, (...) and zoosemiotics, an overarching approach of multi-constructivism is introduced. The paper proposes an analytic model that distinguishes four logical possibilities in representing anthropological difference: Gradualism, Transformativism, Unitarism, and Pluralism. Using this typology, the views of C. Darwin, F. de Waal, M. Tomasello, and T. A. Sebeok regarding the similarities and differences between human and animal capacities for cognition, culture and communication are analyzed. The results indicate systematic differences in the selected narratives by these authors that can be related to the types of underlying ontologies. (shrink)

Contextualists and assessment relativists neglect the expressive dimension of assertoric discourse that seems to give rise to faultless disagreement. Discourse that generates the intuition makes public an attitudinal conflict, and the affective -expressive dimension of the contributing utterances accounts for it. The FD-phenomenon is an effect of a public dispute generated by a sequence of expressing opposite attitudes towards a salient object or state of affairs, where the protagonists are making an attempt to persuade the other side into joining the (...) other’s camp.

The author emphasizes the fact that the largest part of Plato’s Timaeus deals with human nature and offers a detailed account of the constitution of the human body. He then lists the parallels and the differences between the constitution of the world body and the human body. The central part of the paper deals with Plato’s explanation of the persistence of the human body within a bodily environment which causes its dissolution. The author pays a special attention to Plato’s theory (...) of the apparatus which keeps running the processes of respiration, digestion and blood circulation. In the concluding section, the author raises thequestion of the relationship between human body and human soul. He shows that, in Plato’s Timaeus, the human body functions to a large extent independently from human soul. One possible reason for this theory is Plato’s conception of the immortal soul. While the human body exists in order to harbour the immortal soul, the latter does not produce and preserve it nor does it cause its dissolution. It only exercises cognitive and ruling functions in it as long as the body is able to hold together and to detain the soul. (shrink)

This paper analyses Bohr’s complementarity framework and applies it to biosemiotic studies by illustrating its application to three existing models of living systems: mechanistic biology, Barbieri’s version of biosemiotics in terms of his code biology and Markoš’s phenomenological version of hermeneutic biosemiotics. The contribution summarizes both Bohr’s philosophy of science crowned by his idea of complementarity and his conception of the phenomenon of the living. Bohr’s approach to the biological questions evolved – among other things – from the consequences of (...) an epistemological lesson of quantum theory and in light of complementarity of observer as a priori living creature and ex post scientific explanation of the living. In a manifestation of the phenomenon of the living, each model of living system and its description makes accessible – from its own presuppositions, contexts and concepts – some features which are not accessible from the others. Nevertheless, for a general understanding of that phenomenon, incompatible sophisticated approaches are equally necessary. Bohr’s epistemology of complementarity turns out to be a heuristic and methodical framework for testing the extent to which biosemiotics can become one of the special sciences or its potential as a cross-disciplinary branch of study.

In recent philosophy of mind, a series of challenging ideas have appeared about the relation between the body and the sense of touch. In certain respects, these ideas have a striking affinity with Husserl’s theory of the constitution of the body. Nevertheless, these two approaches lead to very different understandings of the role of the body in perception. Either the body is characterized as a perceptual “organ,” or the body is said to function as a “template.” Despite its focus on (...) the sense of touch, the latter conception, I will argue, nevertheless orients its understanding of tactual perception toward visual objects. This produces a distorted conception of touch. In this paper, I will formulate an alternative account, which is more faithful to what it is like to feel. (shrink)

In this paper I challenge the widespread assumption that the conditions for singular reference are more or less the same as the conditions for singular thought. I claim that we refer singularly to things without thinking singularly about them more often than it is usually believed. I first argue that we should take the idea that singular thought is non-descriptive thought very seriously. If we do that, it seems that we cannot be so liberal about what counts as acquaintance; only (...) perception will do. I also briefly discuss and reject semantic instrumentalism. Finally, I argue that while singular reference is cheap, singular thought comes only at a price. (shrink)

The use of teleological language in biology is burdened with many difficulties. Speakers in everyday and scientific discourse confuse functions with purposes and misunderstand functionality, finality, and intentionality. The paper is structured into three sections. In the first part the difference between Platonic supranatural and Aristotelian quasi-natural account of teleology will be explained, with examples from the history of philosophy of biology. The second part will present the Darwinian approach to etiology that constitutes a more sound alternative to the teleological (...) explanation. In the last section I will briefly introduce the teleological bias that is studied by developmental and cognitive psychologists. I believe that this psychological inclination is the real source of intuitive worldviews that are incompatible with contemporary science. (shrink)

Este artigo aborda o debate realismo vs. instrumentalismo (ou antirrealismo) sobre teorias científicas, com foco no debate desdobrado no contexto da Análise do Comportamento (AC). Axiologias realistas são caracterizadas como aquelas segundo as quais (i) as teorias científicas devem buscar identificar e descrever processos, entidades, propriedades e/ou relações extrateóricos de suas esferas de estudo, e (ii) estamos justificados em considerar que elas, quando empiricamente adequadas (ou maduras), são bem-sucedidas nisso. Axiologias instrumentalistas (ou antirrealistas, termos tomados aqui intercambiavelmente), por outro lado, (...) negam (ii), e em alguns casos também (i). No contexto de discussões metateóricas em AC, tanto a partir de sua matriz de pesquisa predominante (comportamentalista radical) quanto de algumas de suas propostas alternativas de fundamentação (como o comportamentalismo molar), formas de instrumentalismo têm sido dominantes. O presente trabalho oferece uma reconstituição lógico-conceitual e um exame do debate recente em AC, problematizando argumentos instrumentalistas frequentes nesse contexto e esboçando a defesa de uma forma atenuada de realismo, próxima da proposta articulada por F. Suppe. (shrink)

Until a decade ago, a comprehensive contestation of the so-called?transitional? paradigm was largely missing in the post-socialist era. This reality changed in the last ten years, especially in the region of former Yugoslavia. Some social movements in this region have started questioning the very essence of the economic and social misconceptions of the post-socialist condition. This paper first provides an elaboration of the very conceptual edifice of the ruling paradigm, as well as a theoretical and methodological framework. It goes on (...) to map out the epistemic discursive content of the respective social movements in Belgrade, Zagreb and Sarajevo, thereby assessing the conceptual content of their critique of the post-socialist transitional paradigm. Finally, given the similarities between Serbia, Croatia and Bosnia and Herzegovina, the paper seeks to explain variations in the critique by how the structural and contextual features impact the perspective from which it is constructed.

Most attempts at defining or elucidating ’weak’ or ’strong’ supervenience introduce various forms of _physical indiscernibility_. After glancing at some definitions, I argue that they must fail if mental events are supposed to be genuinely causally efficacious and non-epiphenomenal. Then I elucidate Davidson’s account of supervenience (’D-supervenience’), first as an abstract relation between a predicate and a set of predicates (to be illustrated by uncontroversial examples), and then as applied to the mental/physical relation. I argue that Davidson must defend that (...) if two events are physically indiscernible in the light of a complete physical theory of the world then they must be identical in the Leibnizian sense (‘L-identity’): physical indiscernibility collapses into L-identity. It follows that mental differences between two numerically different events logically entail physical differences between them. I conclude by demonstrating how the Davidsonian account of the concept can explain some counterexamples to Moore’s approach to supervenience of moral on natural properties. The central tenet in this paper is that supervenience principles based on duplication create, rather than solve, problems in this problem area. (shrink)

Defende-se o argumento de que a lusofonia é um conceito em vias de extinção no pensamento filosófico português e num contexto do interperiferismo intelectual africano contemporâneo. O livro, dividido em 5 partes, procura analisar o estado da arte em relação ao conceito de lusofonia numa perspetiva portuguesa e africana, procurando, a partir daqui, o diálogo intercultural e epistemológico. Na primeira parte, é desenvolvido o estado da arte em que se encontra a ideia de lusofonia de acordo com a literatura produzida (...) no pensamento português. Na segunda parte, elencam-se as premissas para o desenvolvimento do diálogo intercultural e epistemológico. Num terceiro momento, abordam-se as tendências da filosofia africana em geral e dos países africanos de língua oficial portuguesa. A quarta parte procura fazer um diagnóstico do conceito do lusofonia à luz da literatura e pensamento angolanos produzidos até à contemporaneidade. É na quarta e quinta partes que se reflete sobre a falência intercultural do conceito em questão face às contribuições e tendências epistemológicas que estão a ser desenhadas por alguns intelectuais dos Países Africanos de Língua Oficial Portuguesa (PALOP), sobretudo, de autores angolanos. As considerações das várias sensibilidades culturais e das paisagens epistemológicas distintas permitirão apontar para a exigência de uma era pós-lusofonia, que poderá ser inaugurada através da criação de um símbolo estratégico comum, desenhado por todos e para todos os países da CPLP, que reflita uma nova forma de estar e de interagir com o outro num panorama transnacional"--Back cover.

Começamos fazendo uma revisáo da abordagem de tais termos sustentada por Skinner, particularmente sua abordagem das categoriais de termos psicológicos disposicionais. Muito dela é aqui aceito, mas adotamos, como hipótese de trabalho, um desacordo com a premissa de Skinner de que eles sejam (...) irremediavelmente mentalistas.

This article focuses on the social structure of domestic cat colonies, and on the various ways these are represented in ethological literature. Our analysis begins with detailed accounts of different forms of cat societies from the works of Leyhausen, Tabor, and Alger and Alger, and then puts these descriptions into a broader epistemological perspective. The analysis is inspired by the bi-constructivist approach to ethological studies formulated by Lestel, which highlights the position of the ethologist in the constitution of particular animal (...) activities. We propose a third layer should be added to post hoc analyses of ethological enterprises: i.e., the ontological commitments shaping the conceptual framework of a given research. It is through these commitments we find a hierarchical structure in a caged colony of cats, different territorial patterns in the case of urban cats, and egalitarian friendly bonds within the society of a cat shelter. Our critical tri-constructivist approach can be utilized for contemporary biosemiotics as it is centered on a multi-level process of interpretation. (shrink)

In this paper I take a closer look at Sextus Empiricus’ arguments in his Outlines of Pyrrhonism I.25-30 and try to make sense of his account of Skepticism as a goal-directed philosophy. I argue that Sextus fails to mount a convincing case for the view that tranquility, rather than suspension of judgment, is the ultimate goal of his inquiries.

Sextus Empiricus portrays the Pyrrhonian sceptics in two radically different ways. On the one hand, he describes them as inquirers or examiners, and insists that what distinguishes them from all the other philosophical schools is their persistent engagement in inquiry. On the other hand, he insists that the main feature of Pyrrhonian attitude is suspension of judgement about everything. Many have argued that a consistent account of Sextan scepticism as both investigative and suspensive is not possible. The main obstacle to (...) characterizing Pyrrhonism as both investigative and suspensive is the fact that it seems that the mature sceptics, after they have suspended judgement and thus reached tranquillity, have no motivation for further inquiry. Any inquiry they seem to be interested in after they have suspended judgement is the refutation of beliefs needed for maintaining tranquillity. I try to show that the mature sceptics' removal of distress does not ipso facto mean removal of the desire for knowledge. This is because distress is not just a matter of unsatisfied desire, but of belief that one of the opposed appearances must be true, or, more generally, of belief that the truth is the only worthwhile epistemic goal. Having abandoned this belief, the sceptics can still engage in philosophical inquiries. This is because Sextus does not assume that philosophy is the search for truth: it is so only for the dogmatists. In a more general sense, applicable to the sceptics as well, philosophy is just an inquiry into certain things, and for the sceptics, its epistemic goal is still open. (shrink)

Fibring is a meta-logical constructor that applied to two logics produces a new logic whose formulas allow the mixing of symbols. Homogeneous fibring assumes that the original logics are presented in the same way . Heterogeneous fibring, allowing the original logics to have different presentations , has been an open problem. Herein, consequence systems are shown to be a good solution for heterogeneous fibring when one of the logics is presented in a semantic way and the other by a calculus (...) and also a solution for the heterogeneous fibring of calculi. The new notion of abstract proof system is shown to provide a better solution to heterogeneous fibring of calculi namely because derivations in the fibring keep the constructive nature of derivations in the original logics. Preservation of compactness and semi-decidability is investigated. (shrink)

This paper presents a gamified motor imagery brain-computer interface (MI-BCI) training in immersive virtual reality. Aim of the proposed training method is to increase engagement, attention, and motivation in co-adaptive event-driven MI-BCI training. This was achieved using gamification, progressive increase of the training pace, and virtual reality design reinforcing the body ownership transfer (embodiment) into the avatar. From the 20 healthy participants performing 6 runs of 2-class MI-BCI training (left/right hand), 19 were trained for a basic level of MI-BCI operation, (...) with average peak accuracy in the session equal to 75.84\%. This confirms the proposed training method succeeded in improvement of the MI-BCI skills; moreover, participants were leaving the session in high positive affect. Although the performance was not directly correlated to the degree of embodiment, subjective magnitude of the body ownership transfer illusion correlated with the abilities to modulate the sensorimotor rhythm.
