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)

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.

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)

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 .

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 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)

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)

SummaryInfand mortality for the period 1950—70 has been analysied in a North-Swedish isolate, a population characterized by a high incidence of schizopherenic psychoses and other neuorpsychiatric disorders. Infand mortality is higher than in Sweden generally. As many as 45·9% of the deceased infands in the population sccumbed during the first week of their life, compard to 28·1% in the general Swedish population.

In the article, composed of two parts with the titles Spektakl modernistyczny czy seans spirytystyczny? (A modernist spectacle or a spiritistic seance?) and Dlaczego Słowacki niszczy konterfekt księcia Józefa? (Why does Słowacki destroy the portrait of Prince Józef?), presents a contextual interpretation of Jan Lechoń’s poem Duch na seansie (A Ghost at a Seance). The author questions the opinion, which was widespread in literary criticism, that Lechoń together with other members of the Skamander group discredited Romantic poetry and national mythology (...) on the threshold of independence. The analysis of the poem made in the article leads to the conclusion that the poet fought stereotypes deeply rooted in public opinion, which in the eyes of the general public were also reinforced by Slowacki’s poetry. Thus, Słowacki appears at the seance to demystify a belief in the messianic, necrotic and patriotic tone of his poetry, in the bard-creator of the national Gospel, who is endowed with the power to discover absolute truths, and in the „master of the word” as well as the „creator of artistic beauty” as well as the only generally-accepted opinion. Optimistic signs of revival have dominated the symbols of suffering, the talkativeness has been replaced by silence, the word by the iconoclastic deed, the mystical heat by ironic distance. The symbols, images, references to literary texts and other signes of culture help to create a revalued portrait of Słowacki and mould a myth of gray heroism, which is a complete contrast to the myth of the „colourful uhlan”. The destruction of the portrait of Prince Józef Poniatowski and a reference to Piłsudski found in the last line of Karmazynowy poemat (The Crimson Poem) are the signs of the ideological declaration of the young poet, who referring to great Romantic tradition, discovers new and new meanings.

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, 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.
