Building on our diverse research traditions in the study of reasoning, language and communication, the Polish School of Argumentation integrates various disciplines and institutions across Poland in which scholars are dedicated to understanding the phenomenon of the force of argument. Our primary goal is to craft a methodological programme and establish organisational infrastructure: this is the first key step in facilitating and fostering our research movement, which joins people with a common research focus, complementary skills and an enthusiasm to work (...) together. This statement—the Manifesto—lays the foundations for the research programme of the Polish School of Argumentation. (shrink)

We are concerned with formal models of reasoning under uncertainty. Many approaches to this problem are known in the literature e.g. Dempster-Shafer theory [29], [42], bayesian-based reasoning [21], [29], belief networks [29], many-valued logics and fuzzy logics [6], non-monotonic logics [29], neural network logics [14]. We propose rough mereology developed by the last two authors [22-25] as a foundation for approximate reasoning about complex objects. Our notion of a complex object includes, among others, proofs understood as schemes constructed in order (...) to support within our knowledge assertions/hypotheses about reality described by our knowledge incompletely.

A possibilities-based account of practical logic.Andrzej Kisielewicz’s logic without edgesIn this paper I comment on the theses presented in Andrzej Kisielewicz’s book entitled Logic and Argumentation. A Practical Course in Critical Thinking. The author argues that the current way of teaching practical logic is not good, because it is too much based on formal logic. It should be replaced by a comprehensive analysis of reasonable possibilities. I demonstrate that Kisielewicz’s vision of changing the way in which practical logic (...) is taught is a good one. I claim that Kisielewicz proposed a kind of ontologization of logic. I argue that teaching logic and critical thinking need to be complemented by creative thinking techniques. I do not agree with the criticism of traditional logic and formal logic made by Kisielewicz and point out that common sense — so highly valued by Kisielewicz — is deceptive and does not encourage critical thinking.

It is a well-known fact that mathematics plays a crucial role in physics; in fact, it is virtually impossible to imagine contemporary physics without it. But it is questionable whether mathematical concepts could ever play such a role in psychology or philosophy. In this paper, we set out to examine a rather unobvious example of the application of topology, in the form of the theory of persons proposed by Kurt Lewin in his Principles of Topological Psychology. Our aim is to (...) show that this branch of mathematics can furnish a natural conceptual system for Gestalt psychology, in that it provides effective tools for describing global qualitative aspects of the latter’s object of investigation. We distinguish three possible ways in which mathematics can contribute to this: explanation, explication and metaphor. We hold that all three of these can be usefully characterized as throwing light on their subject matter, and argue that in each case this contrasts with the role of explanations in physics. Mathematics itself, we argue, provides something different from such explanations when applied in the field of psychology, and this is nevertheless still cognitively fruitful. (shrink)

Proceedings of a conference held June 26-30, 2007 at Opole University, Poland. -/- This volume explores the three normative sciences that Peirce distinguished (aesthetics, ethics, and logic) and their relation to phenomenology and metaphysics. The essays approach this topic from a variety of angles, ranging from questions concerning the normativity of logic to an application of Peirce’s semiotics to John Coltrane’s “A Love Supreme.”.

This paper is concerned with n-localization property introduced by Newelski and Rosłanowski in [10] and getting it for CS iterations of forcing notions.

The objective of the paper is a presentation and an interpretation of Władysław Stróżewski’s views on aesthetics. Built upon the foundation provided by classical metaphysics, Stróżewski’s aesthetics is simultaneously a continuation of the tradition of phenomenological interpretation of art. Stróżewski extends Roman Ingarden’s aesthetic theory by including the idea of numinous concretion, largely inspired by the works of Rudolf Otto. As a result, this new phenomenological perspective transcends the narrowly understood ‘aesthetics’ of the work of art towards the inherent dimension (...) of the sacred. Moreover, Stróżewski’s scrutiny of the aspect of art that goes beyond the aesthetic reveals an important relationship obtaining between his insights and the theological aesthetics of Hans Urs von Balthasar. Thus Stróżewski’s ideas turn out to be of significance to contemporary aesthetic and theological debates. In particular, he shows the movement of beauty from aesthetic to transcendental, and ultimately towards the sacred, where numinosum is manifested as Mystery. (shrink)

The paper consists of two parts, outlined in the title.I. In the historical science time appears as an element of the historian’s workshop. The historian collects source information, evaluates them and assigns respective dates. Only on the ground of thus “processed” sources may he reproduce the past: events and longer development processes, setting them in time. This dated time is understood colloquially as something objective, which runs one way and may be measured.II. A historian who studies the past reality depends (...) on the extent to which those sources are preserved. As a result of their interpretation, with the use of increasingly excellent research methods, he reproduces that reality. He must carry out an ongoing selection of historical facts found. This exposes him to temptations of such selection of those facts so as to adjust the historical knowledge to serve well the national interests, his own political opinions, etc. In this way the historian exerts influence on social awareness, which may consists of various myths and stereotypes, which sometimes lead to negative social behaviors: aggression, chauvinism, etc. Therefore, for researcher honesty’s sake and in the sense of moral responsibility, he must be careful to be as impartial as possible in his work.

Natural Deduction Natural Deduction is a common name for the class of proof systems composed of simple and self-evident inference rules based upon methods of proof and traditional ways of reasoning that have been applied since antiquity in deductive practice. The first formal ND systems were independently constructed in the 1930s by G. Gentzen and S. Jaśkowski and … Continue reading Natural Deduction →.

The aim of the paper is to examine the nature of moral and legal norms in a broader context: first, taking into account logical and methodological assumptions, second, in the perspective of psychology of emotions and legal policy. The basic subject of the research carried out by Leon Petrażycki was represented by law. Originally, it had a psychological character, not an objective, eternal, and unchanging one. To fully understand the genesis and nature of morality and law, Petrażycki addressed the study (...) of mental phenomena, especially emotional experiences. First, however, he developed appropriate rules of logic and scientific methodology. Then he developed a new classification of mental phenomena, among which the fundamental role is played by bilateral emotions. At some stage, emotions begin to cooperate with cognitive processes, first of all with imaginations. Imaginations of acts, such as theft, betrayal, murder, can cause repulsive emotions, and type imaginations, such as truthfulness, charity, justice can evoke apulsive emotions. On the basis of such associations, judgments are created over time, the content of which becomes a basis for fundamental rules of conduct, that is, for norms. There are two fundamentally different types of norms: moral norms and legal norms. The norms of the first type are imperative and represent the nature of validity, while the norms of the second type are imperative-attributive and they also always entitle someone to something, i.e. they give someone a right. This division determines a fundamental difference between morality and law. (shrink)

Książka stanowi wprowadzenie do twórczości Richarda Rorty'ego, a także próbę osadzenia jej na szerszym tle filozofii współczesnej, ze szczególnym uwzględnieniem filozofii postmodernistycznej. Obecne są w niej szersze analizy stanu kultury współczesnej, a także relacje z istotnych koncepcji obecnych we współczesnej humanistyce, bez których nie można zrozumieć ewolucji współczesnej humanistyki i specjalnej roli, jaką odegrała w niej filozofia Richarda Rorty'ego.

Generational differences in societies are characteristics generally attributed to people’s age that constitute a sociocultural phenomenon. Divisions in the generations differ across nations and extend even to civilizations. Perception and recognition of the different characteristics of each generation affect the cooperation between people in social, political, and economic capacities, and subsequently extend to entities in the public, informal, commercial, and nongovernmental sectors. From the perspective of social justice, it is important to draw attention to how workplace management techniques are used (...) to promote equal opportunities among representatives of various generations.

Spouses exhibit two kinds of behaviours: protective and transgressive. Protective acts are those aiming to overcome current problems, leading to preserving some balance. Transgressive acts are deliberately overstepping everyday marital reality and doing new things in new ways. They lead to changing the relation with the hope of improving it, but also create the risk of deterioration. The more transgressive behaviours spouses exhibit, the more chances they have to get to know each other and experience the joy of being part (...) of a union. Transgressive tendencies stem from a network personality structure and consist of five psychons: cognitive, instrumental, motivational, emotional, and personal. The success of a marriage is the effect of a specific form of transgressive behaviours in marriage exhibited by both spouses, which is recognizing difficulties as they appear, finding their sources, and taking steps together to overcome them.

In terms of psychotransgressionism, personality is a network of five equipollent psychons, the content of which determines the personality’s functioning. The strength and power of the individual psychons underlies the tendency to undertake transgressive actions. In this study, we hypothesized that transgressive spouses are characterized by greater potential strength, greater power of cognitive, instrumental, motivational, emotional, and personal psychons than protective spouses. We operationalized all psychons, created the appropriate research tools, and then studied married couples. Using the Transgression Scale developed (...) by Studenski, we found a group of spouses with higher levels of transgression, and a group of spouses with lower levels of transgression. Transgressive wives are characterized by better knowledge about their husbands’ operational sphere, and are more aware of personal beliefs than protective wives. Similarly, transgressive husbands have greater knowledge of their wives’ operational sphere, stronger cognitive needs, and weaker personal needs than protective husbands. Transgressive husbands are characterized by a positive affective shift and have a greater awareness of personal beliefs than protective husbands. The potential brought into interpersonal relationships by transgressive spouses may create a climate conducive to building a satisfying marital relationship. (shrink)

“Age of life” is one of the essential characteristics that differentiate people. Age perception is also associated with social justice. The concept of age is defined ambiguously. At the same time, the different age criteria also forms the basis of age differentiation and age discrimination. The population lead to distinctions of age groups, age categories, and generations. Differences between generations also lead to Study in the concepts of intergenerationality, intergenerational justice, and intergenerational policies.

Services for single parents constitute a category of child and family services. These services are carried out by public and non-governmental bodies for people who are single parents by the unfortunate events or by their own choice. Individuals come to single parenthood mainly through divorce, separation, birth outside of marriage, child abuse/neglect, death of a partner/widowhood, and adoption.

“Is logic a physical variable?” This thought-provoking question was put forward by Michael Heller during the public lecture “Category Theory and Mathematical Structures of the Universe” delivered on 30th March 2017 at the National Quantum Information Center in Sopot. It touches upon the intimate relationship between the foundations of physics, mathematics and philosophy. To address this question one needs a conceptual framework, which is on the one hand rigorous and, on the other hand capacious enough to grasp the diversity of (...) modern theoretical physics. Category theory is here a natural choice. It is not only an independent, well-developed and very advanced mathematical theory, but also a holistic, process-oriented way of thinking. (shrink)

The problem of precise characterisation of traditional forms of reasoning applied in mathematics was independently investigated and successfully resolved by Jaśkowski and Gentzen in 1934. However, there are traces of earlier interests in this field exhibited by the members of the Lvov-Warsaw School. We focus on the results obtained by Jaśkowski and Leśniewski. Jaśkowski provided the first formal system of natural deduction in 1926. Leśniewski also demonstrated in some of his papers how to construct proofs in accordance with intuitively correct (...) principles. (shrink)

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.

During the global financial crisis of 2007–2009 and the currentCovid-19 debacle, central banks acted quickly, boldly, and effectively. The paper argues that they did so thanks to the lessons learned from the past financial crises, which provided them with opportunities to reconsider their previous beliefs. A case in point is the banking crisis in the United States during the Great Depression of the 1930s that taught central banks to act rapidly and decisively in order to prevent an initial liquidity crisis (...) from escalating into a solvency crisis leading to bankruptcies of banks with potentially disastrous consequences for the entire economy. The paper revisits the consequences of the currency crises of the 1990s, which transformed exchange rate regimes across the world: the EMS one of 1992–1993 that accelerated the launch of the euro, and the Asian one of 1997–1998 resulted in the proliferation of floating exchange rates in emerging economies.
