This book provides an incisive, basic introduction to many-valued logics and to the constructions that are "many-valued" at their origin. Using the matrix method, the author sheds light on the profound problems of many-valuedness criteria and its classical characterizations. The book also includes information concerning the main systems of many-valued logic, related axiomatic constructions, and conceptions inspired by many-valuedness. With its selective bibliography and many useful historical references, this book provides logicians, computer scientists, philosophers, and mathematicians with a valuable survey (...) of the subject.

The article reviews the book Elementy etyki lekarskiej [Issues in Physician Ethics], by Tadeusz Biesaga.

We define a σ-ideal J D on the set of functions ω ω with the property that a real x ∈ ω ω is a Hechler real over V if and only if x omits all Borel sets in J D . In fact we define a topology D on ω ω related to Hechler forcing such that J D is the family of first category sets in D. We study cardinal invariants of the ideal J D.

The article examines the figure of the spy—alongside themes related to espionage—as employed in two books by the Northern Irish writer Ciaran Carson : the volume of poems For All We Know and the novel Exchange Place. Carson’s oeuvre is permeated with the Troubles and he has been hailed one of key writers to convey the experience of living in a modern surveillance state. His depiction of Belfast thematizes questions of terrorism, the insecurity and anxiety it causes in everyday life, (...) as well as the unceasing games of appearances and the different ways of verifying or revising identities. In Carson’s later work, however, these aspects acquire greater philosophical depth as the author uses the themes of doubles, spies, and makeshift identities to discuss writing itself, the construction of subjectivity, and the dialogic relationship with the other. Taking a cue from Paul Ricoeur’s and Julia Kristeva’s conceptions of “oneself as another,” the article examines how Carson’s spy-figures can be read as metaphors for processes of self-discovery and identity-formation, tied to the notion of “self-othering.” Carson employs the figure of the spy—who juggles identities by “donning” different clothes or languages—to scrutinize how one ventures into the dangerous territory of writing, translation and love, as well as to reconsider notions of originality and self-mastery. Ultimately, Carson conceptualizes literature as specially marked by deceptions and metamorphoses, defining in these terms the human condition. (shrink)

In this paper two concepts of the self are presented and contrasted, namely a narrative and a substantial self. The discussed concepts have been variously assessed in contemporary philosophy. It seems, however, that the substantial concept is nowadays an object of severe criticism, whereas the narrative notion celebrates its genuine triumph. In the paper, the author argues that this asymmetry is exaggerated and disproportionate, and opposition between them is not so obvious and clear-cut. The author argues that those two concepts (...) in fact need each other and can, to a certain degree, complement one another. In the article, an example of such complementarity is sketched. (shrink)

This article is about the philosopher as a potential therapist. It starts from tendencies exhibited by a group of contemporary philosophers involved in a so-called human enhancement. Drawing on the newest discoveries of genetics, genetic engineering and pharmacology, they offer a set of therapies aimed at the extensive ‘improvement’ of the human condition. In the second part of the paper, selected ideas concerning philosophical therapy by the Ancient philosophers are presented. They basically employed personal contact, conversation, and wise counselling. Then (...) these two approaches to this kind of therapy are compared and contrasted. The contemporary approaches offer novel, technical ways of intervention but are blind as far as far-reaching goals and the essential goods of human life are concerned. Despite serious cultural differences, the contemporary therapy can learn a lot from the ancients. If the human being is to be treated by philosophers, an integral picture of who the former is must be taken into account. This means that both his interiority and exteriority should be subjects to the therapy. (shrink)

The aim of this paper is to apply a general methodology for constructing statistical methods, which is based on decision theory, to give a statistical description of preferential rankings, with a focus on the rankings’ dependence on categorical variables. In the paper, I use functions of description errors that are based on the Kemeny and Hamming distances between preferential orderings, but the proposed methodology can also be applied to other methods of estimating description errors.

Objective: Present research examined children’s behavioural and cognitive functioning by using data from a screening study based on reports given by parents and teachers, and investigated the strongest predictors of children’s fluid intelligence. Method: Scales: Conners Early Childhood Behaviour Scale and Behaviour Rating Inventory of Executive Function-Preschool were filled out by parents and teachers of preschool children. Raven’s Coloured Progressive Matrices was used to measure fluid intelligence among preschool children. Results: Parent-teacher concordance was low to moderate. Working memory in BRIEF-P (...) estimated by teachers and parents mediated the relationship between inattention/hyperactivity in CEC BEH [S] and fluid intelligence among preschoolers. The difficulties with working memory assessed by teachers and parents were significant predictors of Raven scores; however, predictions based on teachers’ assessments were stronger. Conclusion: Clinicians should collect reports from various observers in order to implement prevention programs and optimize clinical diagnoses for children. Information from both parents and teachers give significant and complementary contribution to understanding difficulties with cognitive and behavioural functioning of preschoolers. (shrink)

The speech act of inquiry is generally treated as a default kind of asking questions. The widespread norm states that one inquires whether p only if one does not know that p. However, the fact that inquiring is just one kind of asking questions has received little to no attention. Just as in the declarative mood we can perform not only assertions, but various other speech acts, like guesses or predictions, so in the interrogative mood we can also make various (...) speech act types. I propose a speech-act-theoretic account of a distinct kind of question that I label exam questions. According to the proposed account, one performs an exam question p only if (i) one has access to the answer to p, and (ii) one does not officially know whether the hearer knows the answer to p. Exam questions satisfy all the necessary requirements of being a distinct kind of speech act. Additionally, my proposal contributes to the recent expansion of the normative approach to a variety of speech acts. (shrink)

Celem artykułu jest poszukiwanie takiej interpretacji obecności i działania Boga w świecie, jaka pozwoliłaby zharmonizować istotne prawdy wiary z naukowym obrazem świata, którego ewolucja jest rządzona przypadkiem i pozbawiona kierunku. Poszukiwanie to jest realizowane w kilku krokach. Odwołując się do różnych koncepcji celowości wskazuje się najpierw, że jeśli można mówić o tym, że świat ma taką cechę, to nie w sensie zmierzania w określonym kierunku, lecz w sensie celowości wewnętrznej: świat ze swej natury jest skierowany na Boga. Współcześnie o Bożej (...) celowości w świecie mówi się często w kategoriach ogólnego lub szczególnego działania Boga. Artykuł, podejmując tę kwestię zmierza do wniosku, że odróżnienie aspektu naturalnego od nadnaturalnego w danym zdarzeniu jest przypuszczalnie niemożliwe. Na jeden z powodów tej niemożliwości wskazuje tzw. zasada domknięcia przyczynowego, dlatego jest ona analizowana w kolejnym punkcie artykułu. Wskazuje się tutaj między innymi na konieczność zrewidowania niektórych klasycznych koncepcji cudu. W odniesieniu zaś do takich przełomowych zdarzeń z dziejów świata, jak powstanie życia czy pojawienie się człowieka, proponuje się hipotezę niedookreśloności celu stworzenia: Bóg może realizować swoje cele w świecie rządzonym przez autentyczny przypadek, jeśli cele te są rozumiane odpowiednio subtelnie. Na przykład, jeśli celem Boga jest pojawienie się w świecie istoty zdolnej do nawiązania z nim świadomego kontaktu, to istota taka niekoniecznie musiała przyjąć postać przedstawiciela gatunku Homo sapiens. Na koniec wskazuje się na panenteizm jako na właściwą, prawdziwie chrześcijańską wizję świata, który jest „losem i przeznaczeniem” samego Boga. W tej perspektywie, detale ewolucyjnego rozwoju świata przestają być religijnie istotne, a sama religia uwalnia się ostatecznie—po części pod wpływem współczesnej nauki—„od błędu i przesądu”.

The paper presents the main idea of point-free theories of space based on Tarski's system of point-free geometry. First, the general idea of the so-called point-free ontology was discussed, as well as the epistemological and methodological reasons for its adoption. Next, Whitehead's method of extensive abstraction, which is the methodological basis for the construction of point-free theories of space, is presented, and the fundamental concepts of mereology are discussed. The main part of the paper is a discussion of Tarski’s geometry (...) of solids, its postulates and metatheoretical properties. The paper ends with a short description of the contribution of Polish researchers to the development of research on point-free theories of space. (shrink)

The aim of this article is an attempt to diagnose the current condition of the philosophy of history, as well as to show its potential in explaining contemporary phenomena and constructing a rational image of the world. Two recent works by Steven Pinker (The Better Angels of Our Nature: Why Violence Has Declined and Enlightenment Now: The Case for Reason, Science, Humanism, and Progress) and the methodological work of Karl Raimund Popper provide a point of reference. And although the works (...) mentioned are not classed as historiosophical (even by Pinker himself), it is the author’s opinion that they fully deserve this title by showing that philosophical reflection on history is something that is sorely needed today, in an age of multiple contradictory diagnoses and radical prophecies.

In his book The Acting Person Karol Wojtyła makes frequent references to the concept of truth. He analyzes truth expressions in various realms, including the epistemological, the metaphysical, the moral, and the axiological. He does not, however, say exactly what he means by truth. This essay analyzes select passages from this book and tries to formulate a coherent understanding of truth as Wojtyła conceived it. This essay puts special emphasis on the question of axiological truth, for this concept is novel (...) within the Thomistic framework of philosophizing and seems to be a consequence of the philosopher’s encounter with phenomenology. In the centre of attention is the first edition of this book published in 1969 in Poland. The main intention of the article is to grasp the very first Wojtylian approach to the problem of truth.

The specific features of adolescent depression - from developmental reaction to clinical syndrome Depression belongs to the most common mental disorders of young people. Yet, its analysis has given rise to many controversies among specialists. One of the crucial raised issues is the question whether it is justified to apply the diagnosis of depression in this age group, considering the fact that intrapsychic mechanisms in adolescents are not yet mature. The theoretical problem arises: to what degree adolescent depression ought to (...) be considered a clinical disorder, rather than a specific developmental reaction. In the present paper, the attempt has been undertaken to tackle the issue. It has been found that the diagnosis of adolescent depression cannot rely on clear-cut diagnostic criteria. Instead, it should rely on clinical assessment of an individual patient. (shrink)

Proofs of two interpolation theorems for Sentential Calculus with Identity as well as some general comments on sentential interpolation are given.

In this paper, I discuss some philosophical problems connected with the notion of regarding the aggregates (_khandha_) as self in the Nikāyas. In particular, I focus on the attitude represented by the formula “I am this” (_esohamasmi_) which may be labeled as that of identifying with the aggregates. In the first part of the paper, I point out and analyze certain similes contained in the Nikāyas which may be read as implying the existence of a distinction between the aggregates and (...) the individual who regards them as self. Then, I consider a hypothesis that the aggregates are not objective constituents of a human being but subjectively experienced representational phenomena. I argue that several Nikāya texts imply the existence of important aspects of a human being, in particular cognitive ones, which are not conceptualized in the terms of the five aggregates. I also discuss the possibility of interpreting _khandha_s as not active in character but as resultant of other cognitive processes. In the last part of the paper I offer a hypothesis that one of the key aspects of regarding the aggregates as self lies in the identification of a human individual with one’s own phenomenal self-representation which results in a mistaken projection of the notions of agency, identity and subjectivity onto something that is inherently devoid of it. I also consider certain parallels between the ideas present in the Nikāyas and the concepts of the modern philosophy of mind. (shrink)

The essay presents some gnoseological themes with reference to the intellect of the separated soul according to John Duns Scotus. Four questions of the Ordinatio IV, d. 45 deal with these themes. In this concret cognitive situation is possible, according to Doctor Subtilis, to get to know the new quiddities of things, in spite of a lack of the empiric cognition. It means leaving behind the conception of generic empiricism and moving to the recognition of more cognitive abilities, as in (...) Aristoteles’s conception. In a post death state intellect continues to have the memory of the quiddities of things known while still connected with the body and can remember concret things and events known by the senses during earthly life. Such a gnoseological notion evidences the cognitive continuity of the human intellect after death, its incorruptibility and cognitive ability at least as such as one had during earthly life. We can see here the connection of philosophic and theological questions, which mutually condition and penetrate each other. According to Scotus it is possible for the intellect of the separated soul to remember the past and to acquire new cognition. Moreover, it is also possible for such an intellect to know the prayers we refer to the blessed in heaven. Such an intellectual approach evidences a strong Augustinian influence on John Duns Scotus’ epistemic conception. (shrink)

I propose an analysis of lying with uninformative speech acts. The orthodox view states that lying is restricted to assertions. However, the growing case for non-assertoric lies made by presuppositions or conventional implicatures challenges this orthodoxy. So far, the only presuppositions to have been considered as lies were informative presuppositions. In fact, uninformative lies were not discussed in the philosophical literature. However, limiting the possibility of lying to informative speech acts is too restrictive. Firstly, I show that standard, uninformative presuppositions (...) can also be lies. Secondly, I extend this picture into uninformative lies made by declarative statements. To implement my proposal, I do not need a new definition of lying. Recently popular commitment-based definitions of lying are able to properly handle uninformative lies. (shrink)

In the paper Weaver's method is adapted to prove interpolation properties of many-valued propositional calculi standard in the sense of Rosser and Turquette. The case of n-valued Lukasiewicz calculi is discussed in connection with the results obtained.

This paper offers a systematic classification and characterization of speech acts and their norms. Recently, the normative approach has been applied to various speech acts, most notably to constatives. I start by showing how the work on the norms of assertion has influenced various approaches to the norms of other speech acts. I focus on the fact that various norms of assertion have different extensions, i.e., they denote different clusters of illocutions as belonging to an assertion. I argue that this (...) has consequences for theorising about norms of other speech acts and generates certain arbitrary divisions. In the central part, I analyse two groups of speech acts. Firstly, ordinary speech acts, like predictions or retractions. Secondly, I indicate how the normative view can be extended to so-called ancillary speech acts, like presuppositions or implicatures. I end with a discussion of possible extensions of the normative approach, focusing on the debate on lying. (shrink)

We investigate definable topological dynamics of groups definable in an o‐minimal expansion of the field of reals. Assuming that a definable group G admits a model‐theoretic analogue of Iwasawa decomposition, namely the compact‐torsion‐free decomposition, we give a description of minimal subflows and the Ellis group of its universal definable flow in terms of this decomposition. In particular, the Ellis group of this flow is isomorphic to. This provides a range of counterexamples to a question by Newelski whether the Ellis group (...) is isomorphic to. We further extend the results to universal topological covers of definable groups, interpreted in a two‐sorted structure containing the o‐minimal sort and a sort for an abelian group. (shrink)

According to the normative approach, speech acts are governed by certain norms. Interestingly, the same is true for classes of speech acts. This paper considers the normative treatment of constatives, consisting of such classes as assertives, predictives, suggestives, and more. The classical approach is to treat these classes of illocutions as species of constatives. Recently, however, Simion (Shifty Speech and Independent Thought: Epistemic Normativity in Context, Oxford University Press, 2021) has proposed that all constatives (i) are species of assertion, and (...) (ii) are governed by the knowledge norm. I defend the classical treatment of constatives and show that Simion’s conclusion is untenable. No taxonomy of speech acts can accommodate such a view. More importantly, we can test whether a particular speech act is an assertion or not. I propose five tests of assertion, the passing of which is a necessary condition for being an assertion. Some constative speech acts fail these tests. Thus, contrary to Simion, not all constatives can be regarded as species of assertion. (shrink)

In the paper * we discuss a distinctive versatility of the non-Fregean approach to the sentential identity. We present many-valued and referential counterparts of the systems of SCI, the sentential calculus with identity, including Suszko’s logical valuation programme as applied to many-valued logics. The similarity of different constructions: many-valued, referential and mixed, leads us to the conviction of the universality of the non-Fregean paradigm of sentential identity as distinguished from the equivalence, cf. [9].

This article attempts to investigate the potential resonances between Paul Ricoeur’s and Julia Kristeva’s theories of otherness as applied to the study of poetry by the Northern-Irish poet Sinéad Morrissey. In all of her five poetry books she explores various forms of otherness and attempts to sketch them in verse. She confronts alterity in many ways, approaching such subjects as the relationship with the body and children, encounters with foreigners, and coming to terms with what is foreign within us. This (...) article engages primarily with her experiences of China, which she recorded in the long poem “China” from her third collection, The State of Prisons. Firstly, this article tackles the question of the body, which is interpreted on the basis of Morrissey’s “post-mortem” poems. Their reading prepares the ground for further explorations of otherness, which Morrissey locates at the very heart of human subjectivity. In this way, she also manages to establish a poetic framework for an ethical consideration of otherness. By investigating the working of the human psyche, Morrissey seems to go along the lines of Kristeva and Ricoeur, who claim that otherness is inextricably linked with the formation of human subjectivity. Taking a cue from their philosophical enquiries, the article also attempts to establish where Kristeva’s and Ricoeur’s philosophies overlap. (shrink)

The paper deals with a possible interdependence between bioethics and transhumanism. It seems that nowadays transhumanism is a separate discipline and we can say at most about bioethical aspects of that. However, a more in-depth investigation reveals that transhumanism is a rival of the contemporary bioethics and tends to take control over it. So, this paper tried to prove that this is not a necessity. There are still vital differences between bioethics and transhumanism and they justify keeping the former separate. (...) The main difference concerns the object of investigation: bioethics is about ethical enquiry of the existing, bodily human being, whereas transhumanism is directed toward a future creature called posthuman. Thus, although there are attempts within transhumanism to replace bioethics, they are still two separate fields of investigation and hence the former is not a new and fully-fledged face of the latter.

In this article we consider a thesis that is quite typical of the philosophy of dialogue: namely, that it is in dialogue that the person comes to be. We present the thesis drawing upon the ideas of Martin Buber, John Macmurray and Calvin Schrag. (The last of these is not himself a fully-fledged philosopher of dialogue, but he does shed some light on the ideas of the others.) We also analyze the ideas developed by Karol Wojtyla, who – although he (...) cannot be classified as a member of this philosophical school – offered his own interpretation of the thesis. The paper shows that philosophers from various schools can find themselves considering much the same thesis, and that this can lead to positive and constructive outcomes. Moreover, the person occupies the center of attention for personalists as well as philosophers of dialogue, so a mutual exchange of insights between them regarding the structure of personhood may well prove vital to a better understanding of the person as an existing reality.
