A consequence relation in the framework of preferential semantics based on the four-valued Belnap-Dunn logic is constructed which proves that the sorites paradoxes are unsound or invalid inferences .

We consider modal epistemic and doxastic logics as intuitively inadequate logics of information, and we outline a modal system of the operator being informed that which avoids inconsistency with our intuitive concept of information. The system has modal structure of the normal modal logic K4, and is sound and complete on the class of all transitive frames. We compare this logic with Floridi’s KTB information logic, and we consider a possibility of extending our system to a dynamic logic.

The paradoxes of vagueness are unsound or invalid reasoning on the ground of preferential semantics based on the four-valued Belnap-Dunn logic.

The concept of inconsistency has become recently the subject of many studies focused on the principle ex contradictione sequitur quodlibet which is a hallmark of the classical inconsistency. Stanisław Jaśkowski was the first who took a non-classical standpoint toward this principle building a system of propositional logic which rejects this classical principle. Rejecting it implies important consequences for the concept of classical negation, and poses the question in which properties the op-eration of negation should be endowed. The intention of this (...) article is to define the concept of inconsistency as well as the concept of negation in a way satisfying the main intuitions natural language users connect with the two notions occurring in propositions containing vague concepts. The vagueness of natural language dis-course leads to the phenomenon of the seeming contradiction characteristic of natural language. A non-standard consequence relation for such a language has been defined in terms of preferential semantics making use of the concept of most classical model. This non-standard consequence relation is applied to the ethical discourse. The concepts introduced in this article have been used to an interpretation of the contradictories of Plato's Parmenides, as well as to the rejection of dialetheism. (shrink)

The main aim of the present article is an outline of an intuitively adequate system of logic of the operator "being informed". Such a system should be different from the familiar systems of epistemic and doxastic logic. The principle of veracity occurring in epistemic logics does not describe adequately the information operator, since the information may be true as well as false. On the other hand, the principle of consistency of beliefs, occurring in doxastic logics, cannot be applied to information, (...) because the information can be inconsistent. Our logic of information, although it is based on Kripke's semantics, includes principles not occurring in the systems of epistemic and doxastic logics, such as the principle of incompleteness of information and the Brouwerian Axiom. We prove that this system is incomplete. We also suggest that it can be generalized to a dynamic logic in the sense of van Benthem. (shrink)

All empirical concepts belonging to natural language are vague. The vagueness of empirical discourse is a source of many semantical problems which have been known since ancient times. One of those problems concerns the so called sorites paradoxes. This article is an attempt to show that the paradoxes are either invalid or unsound inferences. Since classical logic is useless for semantical analysis of such inferences, the article makes use of the Belnap four-valued logic based on the bilattice FOUR. Belnap's logic (...) is the base logic for defining a nonmonotonic consequence relation which prefers models with classical valuations among all valuations of the four-valued logic whenever it is possible. The approach outlined in this article is intuitive, and has more advantages than the supervaluational approach. (shrink)

The first Chinese immigrants arrived in the United States in the 1820s and initially their presence did not result in improving the American perception of China. On the contrary – intense immigration from China led to the development of racist and xenophobic attitudes towards the Chinese, which culminated in the Chinese Exclusion Act of 1882. During the Second World War, China became an important ally of the United States, which triggered a succession of changes to laws barring Chinese immigration. Contemporary (...) Chinese Americans – particularly Taiwanese Americans – can be located in the upper spheres of immigrant population: they are considered to be a well-educated and affluent group. This paper presents the historical and contemporary socio-economic characteristics of the Sino-American population set against a historical and legal background. (shrink)

Celem artykułu jest ukazanie, jak, mimo ustalonych dawno temu postulatów, nakazujących „oczyszczenie” powieści kryminalnej z elementów fantastycznych i nadprzyrodzonych, motywy te funkcjonują we współczesnych utworach z tego gatunku. Jako kontekst należy wskazać zjawiska dające się zauważyć w najnowszej literaturze i kulturze popularnej. Jednym nich jest zmiana postrzegania typowych monstrów z horroru, które stają się zarówno „mniej groźne”, jak i „bardziej ludzkie”. Kolejnym – zakwestionowanie związku postaci (a także zespołu motywów) z fabułą. To na przykład, co było dotąd typowe dla horroru, (...) może pojawić się w powieści kryminalnej. Przeprowadzono analizę wybranych utworów dwojga współczesnych pisarzy: Katarzyny Puzyńskiej (Czarne narcyzy, Martwiec, Rodzanice i Utopce) oraz Wojciecha Chmielarza (Wampir, Zombie i Wilkołak) pod kątem występowania w nich motywów rodem z powieści grozy. We wszystkich omawianych tekstach to ludzie, a nie potwory są zabójcami. W utworach Chmielarza nazwy rodem z horroru to metafory ludzkiego zła lub szaleństwa (autor odwołuje się do zakorzenionych w kulturze znaczeń słów użytych jako tytuły). Katarzyna Puzyńska z kolei za miejsce zdarzeń wybiera małe, często prawie wyludnione miejscowości, gdzie wciąż żywa jest wiara w duchy, wampiry, nawiedzone domy (autorka odwołuje się między innymi do wierzeń słowiańskich). Ukazuje przy tym siłę ludzkich lęków (dotyczy to, w odpowiednich okolicznościach, nawet policjantów), jak również fakt, że istoty ludzkie potrafią być gorsze od potworów z fikcji literackiej. Motywy rodem z horroru funkcjonują w omawianych tekstach na kilka sposobów: 1) jako odwołania do doświadczenia odbiorcy, który odczytuje np. zaprezentowane w powieści nazwy w oparciu o własną wiedzę; 2) jako element lokalnej lub rodzinnej tradycji (żywy najczęściej w miejscach oddalonych od „centrów”); wreszcie 3) ucieleśnienie ukrytych w ludzkiej psychice obsesji i lęków, które niespodziewanie mogą się ujawnić.

This paper presents an argument for the realism about mechanisms, contents, and vehicles of mental representation at both the personal and subpersonal levels, and showcases its role in instrumental rationality and proper cognitive functioning. By demonstrating how misrepresentation is necessary for learning from mistakes and explaining certain failures of action, we argue that fallible rational agents must have mental representations with causally relevant vehicles of content. Our argument contributes to ongoing discussions in philosophy of mind and cognitive science by challenging (...) anti-realist views about the nature of mental representation, and by highlighting the importance of understanding how different agents can misrepresent in pursuit of their goals. While there are potential rebuttals to our claim, our opponents must explain how agents can be rational without having mental representations. This is because mental representation is grounded in rationality. (shrink)

In this paper, I analyze a type of externalist enactivism defended by Riccardo Manzotti. Such radical versions of enactivism are gaining more attention, especially in cognitive science and cognitive robotics. They are radical in that their notion of representation is purely referential, and content is conflated with reference. Manzotti follows in the footsteps of early causal theories of reference that had long been shown to be inadequate. It is commonly known that radical versions of externalism may lead to difficulties with (...) the notion of representation, especially if they cannot help themselves with the notion of syntax. I argue that a type of externalism present in Manzotti’s enactivism may well lead to anti-representationalism. (shrink)

The Republic of Poland is one of the European Union countries that have not yet implemented Directive (EU) 2019/1937 of the European Parliament and of the Council of 23 October 2019 on the protection of persons reporting breaches of EU law (Journal of Laws EC L 305/17 of November 26, 2019). Even though signalling illegal acts is a more and more common occurrence and the social perception of such behaviours is also changing, the “whistleblowers” are not under any legal protection (...) in Poland. In the Sejm of the 9th Term of office, legislative work is underway to pass the act on the protection of persons reporting violations of the law. This will be a legal act containing comprehensive legal protection of whistleblowers. In hereby publication the author focuses on presenting the role of whistleblowers in preventing law violations by employers in the current legal state. In the next part, the above-mentioned draft act is analyzed in terms of provisions ensuring the protection of persons who disclose irregularities. Numerous tragic incidents which could have been avoided if people that were aware of irregularities could safely reveal the information are evidence of how needed an act on whistleblower protection is. The author cites examples of the sinking of the MF Herald of Free Enterprise ferry and the Deepwater Horizon platform as well as the methane explosion in the Halemba mine in Ruda Śląska. (shrink)

In this paper, we defend a representational approach to at least some kinds of non-human psychopathology. Mentally-ill non-human minds, in particular in delusions, obsessive-compulsive disorders and similar cognitive states, are traditionally understood in purely behavioral terms. In contrast, we argue that non-human mental psychopathology should be at least sometimes not only ascribed contentful mental representation but also understood as really having these states. To defend this view, we appeal to the interactivist account of mental representation, which is a kind of (...) a constructive approach to meaning. We follow Mark Bickhard in assuming that only an organism – either human or non-human – capable of detecting its own misrepresentations is representational. However, under his autonomy-based account of biological function these minds are incapable of misrepresentations because these minds are, ex hypothesi, unable to detect error in such representations. To solve this problem, we argue that adding a historical dimension – as in Millikan’s view on mental representations – to Bickhard’s account of function makes mental misrepresentation of mentally-ill minds possible. Using Bickhard’s dynamic account of function, it is possible to explain why delusions and other mental disorders can be seen as locally functional. However, an etiological dimension can further explain why misrepresentations seem to be globally dysfunctional. Even if representational or biosemiotic hypotheses about non-human psychopathology are difficult to confirm empirically, we defend the view that they can enrich our understanding of the causes and development of such pathologies, and may constitute a new progressive research programme.

The article presents the main types of conflict behaviour with the author’s proposal of their classification. The suggested classification is based on the way in which an individual deals with a partner’s adverse influence on his/her self-interest and welfare in a conflict situation. Four possible ways of coping i.e. attack, amicable settlement, defence, and yielding have been distinguished. On the basis of this behaviour classification, the Conflict Behaviour Questionnaire was compiled and its reliability and validity was assessed.

The article discusses the composition of Lysias’ speech, devoted to the history of music, in Pseudo-Plutarch’s treatise On Music. Close attention has been paid to the unifying mechanisms employed by Lysias to create the coherence and unity of the textual construction. The analysis of the speech presented in the article leads to the conclusion that the employment of clearly marked and coordinated two-part units became the most important technique of the organisation of this speech. The first part of each of (...) eleven pairs Lysias’ speech consists of includes quotations from earlier written sources, the second displays comments and interpreting remarks on these citations. This scheme of organisation of the speech provides the internal order and continuity of thought in the historical part of Pseudo-Plutarch’s work. (shrink)

Aristotle'sPolitics1336b20–2 (cited below) proves that in the fourth centuryb.c. there was more than one type of occasion for the presentation of iambic poetry. No surviving ancient testimony describes directly the circumstances of performance of literary iambus in the archaic period. Heraclitus' text which comes from the turn of the sixth and fifth centuriesb.c. suggests that Archilochus' poems, like Homer's, were presented during poetic competitions, but it does not follow that Heraclitus had in mind iambic compositions of the Parian poet.

The dramatic transformation of the Arabian Gulf since the discovery of petroleum resources has called for a new perspective on the situation of women in the region. Qatar is an example of fast-paced industrialization, modernization and profound socio-cultural changes. As the environment transforms literally from day to day, new identities are being forged and social roles renegotiated. The leadership’s vision for the country speaks of gender equality and opportunity for all. This article asks how young Qatari women’s personal stories fit (...) into the national narrative of change and what they see as the best path to agency and empowerment. (shrink)
