This collection of papers is written in the spirit of what is nowadays called 'Logical Philosophy.' The topics addressed include: skepticism and the criterion of truth, situational semantics, computational aspects of possible worlds semantics and question-answer systems, occurrent beliefs, the logical omniscience paradox, paraconsistency, and models of explanatory procedures. (Series: Development in Humanities - Vol. 12).

"The importance of questions is beyond doubt. But the degree of attention paid to them in logic and linguistics is still less than they deserve." What is a question? How to represent questions in formal languages? How to model reasoning in which questions are involved? Can we prove anything by means of pure questioning? How to model goal-directed problem solving? These are the main issues of Andrzej Wi niewski's "Questions, Inferences, and Scenarios." This book offers a state-of-the-art exposition of (...) Inferential Erotetic Logic, that is, an approach to the logic of questions focused on inferences which lead to questions as conclusions. Wi niewski characterizes semantic relations which determine validity of these inferences within the framework of Minimal Erotetic Semantics, applicable to a wide range of formal languages. He elaborates in detail the concept of erotetic search scenario, a tool for modelling problem solving. Moreover, the author presents some applications of Inferential Erotetic Logic in proof theory. Andrzej Wi niewski is one of the most prominent contemporary researchers in the logic of questions. Currently, he is a full professor at the Department of Logic and Cognitive Science, Institute of Psychology, Adam Mickiewicz University in Pozna, Poland. (shrink)

Trwaj¸a}cy na pocz¸a}tku XXI wieku globalny kryzys gospodarczy wymusza podejmowanie przez przedsiȩbiorstwa działań restrukturyzacyjnych. Zmiany te czȩsto wi¸a}ż¸a} siȩ z redukcj¸a} zatrudnienia i kształtowaniem nowych relacji z pracownikami. Outplacement stanowi wci¸a}ż mało popularn¸a} i słabo rozpoznawaln¸a} w Polsce koncepcjȩ odpowiedzialnego zarz¸adzania zwolnieniami pracowników, która pozwala na złagodzenie negatywnych skutków utraty pracy i na skrócenie okresu bezrobocia. Celem opracowania jest przybliżenie istoty i potencjału stosowania outplacementu w Polsce. Podjȩta krytyczna analiza literatury przedmiotu obejmuje wskazanie działań na rzecz antycypacji procesów restrukturyzacji i (...) funkcji zwolnień monitorowanych w ochronie kompetencji kluczowych przedsiȩbiorstw. Określeni zostali główni interesariusze outplacementu w skali regionalnej oraz możliwości organizacji outplacementu przez partnerstwa i pakty lokalne, czyli z udziałem podmiotów sektora komercyjnego, publicznego i pozarz¸adowego. Podsumowanie zawiera wnioski, co do możliwych działań praktycznych. ** The ongoing at the beginning of the XXI century global economic crisis forces companies to take over restructuring actions. These changes are often associated with the reduction of employment and shaping of the new contract agreements with employees. Outplacement continues to be weakly popular and poorly recognized in Poland. It is the concept of responsible management of redundancies, which allows to mitigate the negative effects of losing a job and reduce the period of unemployment. The aim of this paper is to describe the essence and potential of outplacement usage in Poland. Undertaken critical analysis of the literature indicate measures for anticipate restructuring and outplacement functions in the protection of key enterprises competencies. Outplacement key stakeholders at the regional level were specified. Possibilities of outplacement organization including the local partnerships and pacts were explored. In other words, the cooperation of the commercial, public and non-governmental sector entities. Summary include proposals for further practical actions. (shrink)

Academic dishonesty has serious consequences for human lives, social values, and economy. The main aim of the study was to explore a model of relations between personal and cultural variables and academic dishonesty. The participants in the study were N = 2,586 individuals from nine countries (Pakistan, Israel, Italy, India, the USA, Peru, Romania, Ghana, and Poland). The authors administered the Academic Dishonesty Scale to measure academic dishonesty, the Kessler Psychological Distress Scale to measure distress, the Almost Perfect Scale – (...) Revised to measure perfectionism, the Brief Self-Control Scale to measure self-control, and the Singelis Scale to measure independent self-construal. The results showed that the theoretical model was well fitted to the dataset in six countries: Pakistan, the United States, Romania, Ghana, Israel, and Poland. However, it was not well fitted in Italy, India, and Peru. Our results also showed that perfectionism significantly predicted academic dishonesty, but not in all countries. Self-control significantly predicted cheating, falsification, and plagiarism in the USA. Moreover, we found that distress was related to cheating o0nly in Ghana. Finally, independent self-construal predicted academic dishonesty. Our findings provide a cross-cultural contribution to the debate on academic dishonesty by highlighting its significant predictors and may inform interventions aimed at eliminating it. Our results can be used in preventing and curbing academic dishonesty. Knowledge on cross-cultural differences can be useful in international education for example, as an indicator accepting or relaxing attitude toward academic dishonesty in students from different countries.

First-order logic is formalized by means of tools taken from the logic of questions. A calculus of questions which is a counterpart of the Pure Calculus of Quantifiers is presented. A direct proof of completeness of the calculus is given.

We classify two of Bertrand Russell's theories of events within the point-free ontology. The first of such approaches was presented informally by Russell in ‘The World of Physics and the World of Sense’ (Lecture IV in Our Knowledge of the External World of 1914). Based on this theory, Russell sketched ways to construct instants as collections of events. This paper formalizes Russell's approach from 1914. We will also show that in such a reconstructed theory, we obtain all axioms of Russell's (...) second theory from 1936 and all axioms of Thomason's theory of events from 1989. Russell's work certainly influenced the works of Stanisław Leśniewski, his student Alfred Tarski, and Czesław Lejewski – prominent members of the Lvov-Warsaw School (LWS). We see our work in the tradition of the research of Leśniewski and Tarski. Building on the technical tools developed in this environment and in the spirit of the traditional research of the LWS, we engage here, in particular, with two classic works by Russell on fundamental ontology.

Inferential erotetic logic and inquisitive semantics give accounts of questions and model various aspects of questioning. In this paper we concentrate upon connections between inquisitiveness, being the core concept of INQ, and question raising, characterized in IEL by means of the concepts of question evocation and erotetic implication. We consider the basic system InqB of INQ, remain at the propositional level and show, inter alia, that: a disjunction of all the direct answers to an evoked question is always inquisitive; a (...) formula is inquisitive if, and only if it evokes a yes–no question whose affirmative answer expresses a possibility for the formula; inquisitive formulas evoke questions whose direct answers express all the possibilities for the formulas, and each question erotetically implies a question whose direct answers express the possibilities for the direct answers to the implying question.

The main theorem says that a consequence operator is an effective part of the consequence operator for the classical prepositional calculus iff it is a consequence operator for a logic satisfying the compactness theorem, and in which every finitely axiomatizable theory is decidable.

The paper contains an exposition of some non standard approach to gentzenization of modal logics. The first section is devoted to short discussion of desirable properties of Gentzen systems and the short review of various sequential systems for modal logics. Two non standard, cut-free sequent systems are then presented, both based on the idea of using special modal sequents, in addition to usual ones. First of them, GSC I is well suited for nonsymmetric modal logics The second one, GSC II (...) is devised specially for symmetric, i.e. Blogics. GSC I and GSC II are not different formalizations, from the theoretical point of view GSC I may be seen as a simplification of the more general approach present in GSC II. They are considered separately, mainly because Blogics demand different, and more complicated, strategy in completeness proof, whereas non symmetric logics are easily and uniformly characterised by means of Fitting's Consistency Properties. The weakest modal logic captured by this formalization is minimal regular logic C, but many stronger logics are obtainable by addition of suitable structural rules, which conforms to Do en's methodology. Both variants of GSC satisfy also other, besides cut-freedom, desirable properties. (shrink)

Les règlements de compte en Pologne après la chute du communisme ont pris un tour particulier. Entre les désirs d'une réconciliation nationale et d'une justice publique, les Polonais ont oscillé. A partir de 1997, s'est finalement mis en place un processus dit de « lustration » qui consiste à demander aux diffé­rents titulaires de responsabilité publique de déclarer leurs activités sous le communisme. Un débat s'est instauré à ce propos, dans lequel les médias, s'appuyant sur les sondages ont joué un (...) rôle important. Autre signe du désir de la Pologne de changer de mémoire, la modification des noms des villes et des rues : où l'on voit que l'on n'efface pas facilement le passé.The settling of accounts in Poland after the fall of Communism took a specific turn as the Polish popu­lation hesitated between its desire for national reconciliation and for public justice. Eventually, from 1997, the process known as "lustration" was introduced, whereby the various holders of public office were required to state their activities under Communism. This gave rise to a debate in which the media, drawing on opinion polls, played an important part. Another sign of Poland' s desire to alter its memory was the changing of street and city names, which shows that it is not so easy to erase the past. (shrink)

We provide an application of a sequent calculus framework to the formalization of definite descriptions. It is a continuation of research undertaken in [20, 22]. In the present paper a so-called free description theory is examined in the context of different kinds of free logic, including systems applied in computer science and constructive mathematics for dealing with partial functions. It is shown that the same theory in different logics may be formalised by means of different rules and gives results of (...) varying strength. For all presented calculi a constructive cut elimination is provided. (shrink)

In pre-revolutionary Russia, law was criticized from many points of view: in the name of Christ or the name of Marx, in defense of anarchism or of an idealized autocracy, on behalf of the "Russian soul" or of universal progress towards socialism. Examining the rich tradition of hostility to law, Walicki presents those Russian thinkers who boldly challenged this legacy of anti-legal prejudice by developing liberal philosophies of law, vindicating the value of human rights and rule of law. He discusses (...) six leading theorists--Boris Chicherin, Vladimir Soloviev, Leon Petrazycki, Pavel Novgorodtsev, Bogdan Kistiakovsky, and Sergius Hessen--all of whom viewed law in the context of wider philosophical and social problems.

In this paper, I argue that if the process of globalization leads to more severe social discrepancies that are not acceptable to many groups of people, then globalization would become the factor of primary relevance that threatens democracy; but if globalization and the present democratic order manage to solve social problems, then globalization will be a factor supporting the democratic way of thinking that is not oriented to exclusiveness. Globalization, I believe, coincides rather with a way of thinking that is (...) non-xenophobic and which refuses to see moral thinking in the strict dichotomy of good and evil. (shrink)

Ein Grundbedürfnis der Menschheitsgeschichte ist die Suche nach gemeinsamen ethischen Massstäben. Das Naturrecht hat sich besonders in der christlichen Interpretation zu einem universalen "Wegweiser" in der abendländischen Geistesgeschichte herausgestellt. Es bietet allgemein gültige Handlungsorientierungen. Die gegenwärtige Pluralisierung durch verschiedene normative anthropologische Entwürfe bewirkt eine allgemeine Verunsicherung. Diese globalen Entwicklungen sind der Anlass, das Naturrecht neu zur Geltung zu bringen, um den heutigen ethischen Herausforderungen gerecht zu werden.
