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

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)

Medical tourists, persons that travel across international borders with the intention to access non-emergency medical care, may not be adequately informed of safety and ethical concerns related to the practice of medical tourism. Researchers indicate that the sources of information frequently used by medical tourists during their decision-making process may be biased and/or lack comprehensive information regarding individual safety and treatment outcomes, as well as potential impacts of the medical tourism industry on third parties. This paper explores the feedback from (...) former Canadian medical tourists regarding the use of an information sheet to address this knowledge gap and raise awareness of the safety and ethical concerns related to medical tourism.

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.

BackgroundMedical tourism, the practice of persons intentionally travelling across international boundaries to access medical care, has drawn increasing attention from researchers, particularly in relation to potential ethical concerns of this practice. Researchers have expressed concern for potential negative impacts to individual safety, public health within both countries of origin for medical tourists and destination countries, and global health equity. However, these ethical concerns are not discussed within the sources of information commonly provided to medical tourists, and as such, medical tourists (...) may not be aware of these concerns when engaging in medical tourism. This paper describes the methodology utilized to develop an information sheet intended to be disseminated to Canadian medical tourists to encourage contemplation and further public discussion of the ethical concerns in medical tourism.MethodsThe methodology for developing the information sheet drew on an iterative process to consider stakeholder feedback on the content and use of the information sheet as it might inform prospective medical tourists’ decision making. This methodology includes a literature review as well as formative research with Canadian public health professionals and former medical tourists.ResultsThe final information sheet underwent numerous revisions throughout the formative research process according to feedback from medical tourism stakeholders. These revisions focused primarily on making the information sheet concise with points that encourage individuals considering travelling for medical tourism to do further research regarding their safety both within the destination country, while travelling, and once returning to Canada, and the potential impacts of their trip on third parties. This methodology may be replicated for the development of information sheets intending to communicate ethical concerns of other practices to providers or consumers of a certain service. (shrink)

Pro-social basic human values and civic involvement. The moderating role of survival vs self-expression cultural context The present study investigated a hypothesis that the pro-social values differentiated by S. Schwartz's model of basic human values - universalism and benevolence - would positively predict civic involvement. Most importantly, authors expected that the type of pro-social value that would play a dominant motivational role would depend on moderating role of the level of self-expression and benevolence - cultural value dimension developed by R. (...) Inglehart. Based on discriminant function analyses performed on the data gathered in 17 European countries through the European Social Survey conducted in 2002, authors found that universalism predicts civic involvement only in self-expression countries, whereas the role of benevolence is rather neglectable and independent of the cultural context. The results are discussed with reference to cross-cultural differences in Europe. (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)

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)

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.

HERMENEUTIC INDICATORS OF PRESENTING THE HISTORY OF PHILOSOPHY The aim of the article is to discuss Hans-Georg Gadamer’s and Paul Ricoeur’s hermeneutic way of understanding the history of philosophy. I assume that hermeneutic reference to philosophical past appears as a unique dialogue with tradition, whereas their way of understanding the history of philosophy might be defined as “hermeneutic interpretation of tradition.” In order to show what its indicators are, I characterize the conception of hermeneutic experience (H.-G. Gadamer) as well as (...) the issue of the interpretation process (P. Ricoeur). Those thinkers are convinced that understanding of the history of philosophy involves the recognition of our own historicity. Keywords: HANS-GEORG GADAMER, PAUL RICOEUR, HISTORY OF PHILOSOPHY, HERMENEUTICS. (shrink)

The concept of narrow content is still under discussion in the debate over mental representation. In the paper, one-factor dimensional accounts of representation are analyzed, particularly the case of Fodor's methodological solipsism. In methodological solipsism, semantic properties of content are arguably eliminated in favor of syntactic ones. If “narrow content” means content properties independent of external factors to a system (as in Segal's view), the concept of content becomes elusive. Moreover, important conceptual problems with one-factor dimensional account are pointed out (...) as a result of analysis arguments presented by J. Searle, S. Harnad and T. Burge. Furthermore, these problems are illustrated with psychological and ethological examples. Although understanding content as partially independent from contextual factors allows theorists to preserve content properties, it seems that understanding content in total abstraction from external factors of these properties is implausible. As a result, internalism is rejected in favor of externalism. (shrink)
