This book is a study in the logic of questions (sometimes called erotetic logic). The central topics in erotetic logic have been the structure of questions and the question-answer relationship. This book doesn't neglect these problems, but much of it is focussed on other issues. The main subject is the logical analysis of certain relations between questions and the contexts of their appearance. And our aim is to elaborate the conceptual apparatus of the inferential approach to the logic of questions. (...) Questions are asked for many reasons and for different purposes. Yet, before a question is asked or posed, a questioner must arrive at it. In many cases arriving at a question resembles coming to a conclusion: there are some premises involved and some inferential thought processes take place. If we agree that a conclusion need not be "conclusive", we may say that sometimes questions can play the role of conclusions. But questions can also perform the role of premises: we often pass from some "initial" question to another question. In other words, there are inferential thought processes - we shall call them erotetic inferences - in which questions play the roles of conclusions or conclusions and premises. The inferential approach to the logic of questions focusses its attention on the analysis of erotetic inferences. This book consists of eight chapters. (shrink)

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.

The famous theory of undecidable sentences created by Kurt Godel in 1931 is presented as clearly and as rigorously as possible. Introductory explanations beginning with the necessary facts of arithmetic of integers and progressing to the theory of representability of arithmetical functions and relations in the system (S) prepare the reader for the systematic exposition of the theory of Godel which is taken up in the final chapter and the appendix.

This book introduces the English-speaking reader to the thought of Stanislaw Brzozowski (1878-1911), the outstanding Polish philosopher and literary critic. Although practically unknown in the West, Brzozowski is an important but neglected forerunner of the intellectual tradition of `Western Marxism', most commonly associated with Georg Lukács and Antonio Gramsci. -/- Concentrating first on the early phase of Brzozowski's thought, Professor Walicki goes on to analyse his ideas on the working class and its relation to the intelligentsia and contemporary working-class ideologies. (...) Finally he deals with aspects of his thought which go beyond the Marxian problematic and round off the intellectual portrait of the man. -/- Brzozowski's anti-naturalistic approach resulted in a radical reinterpretation of Marxism which dealt with many of the problems of the revolt against positivism in European philosophy. Professor Walicki argues that the retrieval of the philosophical and humanist aspect of Marxism, and its separation from the Engels-inspired `scientific Marxism', was the achievement of Brzozowski and not, as frequently assumed, of Lukács, who came to similar conclusions only some ten years later. -/- By placing Brzozowski within the cross-currents of the various philosophical, sociological, literary, and political streams of Western and Eastern European thought in which Marxism was situated, Professor Walicki produces a fascinating study of an early East European challenge to orthodox Marxism.

In this paper, I take as a starting point an exchange between Henryk Elzenberg and Roman Ingarden concerning the mode of existence of values. Based on their correspondence, I attempt to trace the missed and lost opportunities for dialogue between the two great Polish axiologists. I demonstrate that while sharing an intense interest in the issue of the existence of values, they addressed them independently and in divergent ways. Following that, I also look at the posthu- mous fate of their (...) unfinished dialogue and argue that their work opens a space for further exploration of the ontology of values. (shrink)

We continue investigations of reasonable ultrafilters on uncountable cardinals defined in previous work by Shelah. We introduce stronger properties of ultrafilters and we show that those properties may be handled in λ-support iterations of reasonably bounding forcing notions. We use this to show that consistently there are reasonable ultrafilters on an inaccessible cardinal λ with generating systems of size less than $2^\lambda$ . We also show how ultrafilters generated by small systems can be killed by forcing notions which have enough (...) reasonable completeness to be iterated with λ-supports. (shrink)

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 →.

Artykuł porusza problem rozumienia w filozofii psychiatrii. Autor koncentruje się na klasycznym już podziale w naukach humanistycznych – na rozumienie/wyjaśnianie oraz nomotetyczne/idiograficzne - i próbuje nakreślić jego konsekwencje dla psychiatrii i problematyki zaburzeń psychicznych. Przegląd wybranych zagadnie metodologicznych filozofii psychiatrii ujawnia antropologiczne aspekty nowożytnej psychiatrii oraz ograniczenia modelu biomedycznego. Ostatnia część artykułu omawia wybrany przypadek kliniczny, aby wskazać na praktyczne konsekwencje indywidualnego i idiograficznego podejścia do psychiatrii.

One of the main goals of modern philosophy was to achieve an in-depth insight into the foundations of empirical knowledge. The problem was expected to be resolved by the analysis of experience. However, the road to a plausible account of experience was at the very beginning obstructed by turning the analysis into a search for clear and distinctive elements of experience and by sticking to purely intellectual intuition as means of this analysis. Moreover, clear and distinctive elements of experience were (...) thought of as the basis of cognitive certainty. Both psychology and philosophy, at least until the nineteen-thirties, were deeply influenced by this essentially rationalistic conception of sensor experience. It is gestalt psychology and phenomenology that should be merited for overcoming that ill-conceived model. Only by taking into account the immediate sensor relation between the human subject and the environment, it is possible to show the kind of unity which is the prerequisite of human intellect.

The ancient Greeks used the term catharsis for the cleansing of both the body by medicine and the soul by art. In this inspiring book, internationally renowned cardiologist Andrzej Szczeklik draws deeply on our humanistic heritage to describe the artistry and the mystery of being a doctor. Moving between examples ancient and contemporary, mythological and scientific, Catharsis explores how medicine and art share common roots and pose common challenges. The process of diagnosis, for instance, belongs to a world of (...) magic and metaphor; the physician must embrace it like a poem or painting, with particular alertness and keen receptivity. Speculation on ways to slow aging through genetics, meanwhile, draws directly on the dream of immortality that artists and poets have nourished through the ages. And the concept of catharsis itself has made its way from the writings of Aristotle to today's growing interest in the benefits of music to health, especially in newborns. As Szczeklik explores such subjects as the mysteries of the heart rhythm, the secret history of pain relief, the enigmatic logic of epidemics, near-death or out-of-body experiences, and many more, he skillfully weaves together classical literature, the history of medicine, and moving anecdotes from his own clinical experiences. The result is a life-affirming book that will enrich the healing work of patients and doctors alike and make an invaluable contribution to our still-expanding vision of the art of medicine. (shrink)
