Boolean connexive logic is an extension of Boolean logic that is closed under Modus Ponens and contains Aristotle’s and Boethius’ theses. According to these theses a sentence cannot imply its negation and the negation of a sentence cannot imply the sentence; and if the antecedent implies the consequent, then the antecedent cannot imply the negation of the consequent and if the antecedent implies the negation of the consequent, then the antecedent cannot imply the consequent. Such a logic was first introduced (...) by Jarmużek and Malinowski, by means of so-called relating semantics and tableau systems. Subsequently its modal extension was determined by means of the combination of possible-worlds semantics and relating semantics. In the following article we present axiomatic systems of some basic and modal Boolean connexive logics. Proofs of completeness will be carried out using canonical models defined with respect to maximal consistent sets. (shrink)

The current paper studies the formal properties of the Global Reflection Principle, to wit the assertion “All theorems of$\mathrm {Th}$are true,” where$\mathrm {Th}$is a theory in the language of arithmetic and the truth predicate satisfies the usual Tarskian inductive conditions for formulae in the language of arithmetic. We fix the gap in Kotlarski’s proof from [15], showing that the Global Reflection Principle for Peano Arithmetic is provable in the theory of compositional truth with bounded induction only ($\mathrm {CT}_0$). Furthermore, we (...) extend the above result showing that$\Sigma _1$-uniform reflection over a theory of uniform Tarski biconditionals ($\mathrm {UTB}^-$) is provable in$\mathrm {CT}_0$, thus answering the question of Beklemishev and Pakhomov [2]. Finally, we introduce the notion of a prolongable satisfaction class and use it to study the structure of models of$\mathrm {CT}_0$. In particular, we provide a new model-theoretical characterization of theories of finite iterations of uniform reflection and present a new proof characterizing the arithmetical consequences of$\mathrm {CT}_0$.

In this paper, we investigate abstract model-theoretic properties which hold for models in which a truth or satisfaction predicate for a sublanguage of the signature is definable. We analyze in which cases those properties in fact ensure the definability of the respective truth predicate. In some cases, we formulate different axiomatic theories which are indispensable for such properties to hold and we analyze the mutual definability relations between those theories.

This text reviews David Megger’s 2021 book entitled _Justice in Welfare Economics. __Libertarianism and the Austrian School_ (in Polish: _Sprawiedliwość w ekonomii dobrobytu, liberatarianizm i szkoła austriacka_). The review takes a critical approach, highlighting the most significant aspects of the presented considerations and emphasising their uniqueness and complexity. I intend to extensively discuss the author’s theses concerning the modification of the fundamental claims of Austrian school representatives about justice and welfare, highlighting both their strengths and weaknesses.

The main purpose of the paper is to develop a concept of _model uncertainty_ as opposed to the existing and well-established concept of model risk. Up to date the broad literature on probability not only developed complete probability systems, but also correctly noticed limitations of probability calculus. Despite the acknowledgement of such probability restrictions, drawbacks of modeling are often related to model risk. We present an argument here to distinguish a feature limiting models even further: model uncertainty. The tenets of (...) it already exist in the literature on probability, but were not properly emphasized while the idea of model risk was developed. Our plan it to start with a broad overview of the existing knowledge about probability in order to start with fundamental principles. From them we are deriving a new concept of model uncertainty.

I would like to identify a certain weakness which is characteristic, in my view, of the ‘critique of the model of representation’ or of the project of ‘overturning the hegemony of representation’, popular in philosophical circles inspired by Heidegger’s writings. According to Heidegger’s influential interpretation of modernity — which, by the way, is indebted to Hegelian philosophy of history — the logic of the development of modern thought is entirely subordinated to one idea: the idea of absolute domination of the (...) subject as the power of discursive representation. This interpretation provides a unified vision of the history of modernity as the history of increasing relativization of all aspects of reality to the subject and its capacity to represent and to form judgements. This unified picture of modernity constitutes the common point of reference and inspiration for many intellectual enterprises under the banner of deconstruction, hermeneutics, philosophy of difference, and the critique of Enlightenment. The same interpretation is explicitly or tacitly assumed in postmodernist accounts of contemporary culture, according to which our task as post-modern thinkers is to abandon, overthrow, and shatter the model of representation.

Over the past decade work engagement has gained both business and academia attention. With growing number of studies and meta-analyses the concept of work engagement is one of the pillars of positive work and organizational psychology. This systematic review presents the current state of research on work engagement in Poland. Results confirmed that work-engagement studies have not yet reached the threshold to conduct meta-analysis. The review of measurement methods and synthesis of findings allows to identify strengths and gaps in Polish (...) studies. Discussion of limitations and biases in current research is accompanied with urge to overcome them and develop thriving stream of research on work engagement. (shrink)

This article explores the conception of self-knowledge in book 10 of Augustine’s De Trinitate. Augustine starts from the worry in Plato’s Meno that one cannot search for something entirely unknown and engages with Plotinus, Ennead 5.3 in developing his own understanding of the mind’s self-knowledge. He concludes that this knowledge is paradoxical in nature: it is necessary and, at the same time, futile; and it is separated from the knowledge of God. Augustine reaches this point by rejecting the Aristotelian identity (...) of the knower with the known, as well as by grounding self-knowledge in the fact of the mind’s intimate presence to itself. Ultimately, self-knowledge appears to be an ‘objectless’ knowledge, a knowledge that the mind exists rather than knowledge of what the mind is. (shrink)

Celem tego artykułu jest analiza powiązań jakie zachodzą pomiędzy fenomenami metodyczności i etyczności we wczesnej filozofii Martina Heideggera. Nie pojmuje się tu ani metody jako procedury badawczej prowadzącej do określonych rezultatów, ani etyki jako odrębnej dyscypliny filozoficznej posiadająca własne pole przedmiotowe. Chodzi o dwa wymiary bycia, które wzajemnie się implikują. Na początku badana jest fenomenologia jako sposób pytania o bycie, a następnie zostaje wydobyty metodyczny sens postępowania, które Heidegger określa mianem formalnego wskazywania. W rezultacie metodyczność zostaje odsłonięta jako droga prowadząca (...) do bycia jako źródła sensu, droga, którą zapewnia samo to bycie. W dalszej kolejności analizowany jest fenomen filozofowania, który Heidegger interpretuje jako wyraźne transcendowanie. Transcendowanie to ostatecznie okazuje się wolnością, której fundamentalny charakter stanowi pozwolić-być, kładące jednocześnie fundament pod odpowiedzialność. Odpowiedzialność zaś jest odpowiedzią udzielaną na wezwanie bycia i przyjmuje postać (zobo)wiązania Dasein wobec bytu, któremu pozwoliło ono być. Etyczność odsłania się tym samym jako domaganie się takiej odpowiedzi na wezwanie bycia, która sprosta ciężarowi jego przesłania. W tym miejscu na jaw wychodzi spotkanie etyczności z metodycznością – ta ostatnia jest drogą do otwartości bycia zapewnioną przez samą tę otwartość, by postulat etyczności mógł zostać spełniony. Oznacza to, że etyczność domaga się metodyczności, a metodyczność (a wraz z nią filozofowanie) niesie ze sobą konsekwencje etyczne dla rozumienia bycia i bytu. Słowa kluczowe: Heidegger, fenomenologia, metoda, etyka, wolność, odpowiedzialność. (shrink)

The purpose of this paper is consideration about issues of work of art’s autonomy in regard to its creator and issue of artistic freedom according to privative theory of art connected to Aristotelian-Thomistic philosophy. Presented philosophy of art emphasizes analogical feature of art, and it includes in art’s domain every intentional type of creation in unlike modern tendency to unification arts around idea of beauty whilst distancing from twentieth-century anti-essentialism. The main function of art understood in this way is replenishing (...) privations found by man in the world. The essence of art is realization by creator his concept. From this point of view the aim of whole creation is good of work for itself which leads to recognition of autonomy and self-sufficiency of work of art. (shrink)

The aim of the paper is to discuss the idea of dialogue with nature. Even though the idea of dialogue with animals, plants – even objects of inanimate nature – is well known, it has usually been treated as an expression of a naive or folk view. Yet, it has recently gained in importance as an idea that is used to describe an ecological approach to natural environment and tends to be treated as a foundation for an ecological culture. A (...) noteworthy contribution to the reconsideration of the concept of human-nature dialogue has also been given by a number of contemporary philosophers who have offered an environmental reinterpretation of phenomenology and hermeneutics based on, among other things, Martin Buber’s concept of the I-You relationship. The paper will focus on two aspects of the concept of dialogue, namely on its epistemological and ethical implications. Following Erazim Kohák’s theory, which will be presented as a key figure of a particular manner of speaking about nature, one that leads to ecological personalism. (shrink)

The notion of implicit commitment has played a prominent role in recent works in logic and philosophy of mathematics. Although implicit commitment is often associated with highly technical studies, it remains an elusive notion. In particular, it is often claimed that the acceptance of a mathematical theory implicitly commits one to the acceptance of a Uniform Reflection Principle for it. However, philosophers agree that a satisfactory analysis of the transition from a theory to its reflection principle is still lacking. We (...) provide an axiomatization of the minimal commitments implicit in the acceptance of a mathematical theory. The theory entails that the Uniform Reflection Principle is part of one’s implicit commitments, and sheds light on why this is so. We argue that the theory has significant epistemological consequences in that it explains how justified belief in the axioms of a theory can be preserved to the corresponding reflection principle. The theory also improves on recent analyses of implicit commitment based on truth or epistemic notions. (shrink)

We introduce a principle of local collection for compositional truth predicates and show that it is arithmetically conservative over the classically compositional theory of truth. This axiom states that upon restriction to formulae of any syntactic complexity, the resulting predicate satisfies full collection. In particular, arguments using collection for the truth predicate applied to sentences occurring in any given (code of a) proof do not suffice to show that the conclusion of that proof is true, in stark contrast to the (...) case of the induction scheme. We analyse various further results concerning end-extensions of models of compositional truth and the collection scheme for the compositional truth predicate. (shrink)

This paper is a follow-up to [4], in which a mistake in [6] (which spread also to [9]) was corrected. We give a strenghtening of the main result on the semantical nonconservativity of the theory of PT−with internal induction for total formulae${(\rm{P}}{{\rm{T}}^ - } + {\rm{INT}}\left( {{\rm{tot}}} \right)$, denoted by PT−in [9]). We show that if to PT−the axiom of internal induction forallarithmetical formulae is added (giving${\rm{P}}{{\rm{T}}^ - } + {\rm{INT}}$), then this theory is semantically stronger than${\rm{P}}{{\rm{T}}^ - } + (...) {\rm{INT}}\left( {{\rm{tot}}} \right)$. In particular the latter is not relatively truth definable (in the sense of [11]) in the former. Last but not least, we provide an axiomatic theory of truth which meets the requirements put forward by Fischer and Horsten in [9]. The truth theory we define is based on Weak Kleene Logic instead of the Strong one. (shrink)

The paper addresses the question how descriptive language is used to express legal norms. Sentences we find in legislative acts, i.e. statutes, constitutions and regulations, express legal norms. Linguistically speaking, there are various grammatical and lexical ways of expressing norms, such as imperative mood, modal verbs, deontic verbs, etc. However, norms may also be expressed by descriptive sentences, namely sentences in present or future tense and indicative (declarative) mood (i.e. _The minister determines the tax rate_). In many civil law countries (...) (including Poland), this is a very common, if not the default, form of expressing norms in legislative texts. Often presented as a legal peculiarity, this phenomenon has yet to draw much academic attention. The normative meaning of descriptive sentences is usually attributed to purely pragmatic factors stemming from our shared assumptions about the legal system. However, a closer look reveals that similar grammatical constructions are ubiquitous in everyday communication and in different languages. We tend to utter various sorts of directives using descriptive sentences (_Now we add a spoon of salt to the sauce_; _credit cards are not accepted_). This suggests the possibility for a linguistic (as opposed to exclusively legal) explanation. This paper aims to offer such an explanation. Rather than resorting to formal semantics, so prevalent in legal theory, it borrows from Cognitive Linguistics to reveal the cognitive underpinnings of our surprising tendency to express normativity in descriptive terms. This involves four different, yet complementary, theories. Firstly, the theory of conceptual metaphor by George Lakoff and Mark Johnson which explains the phenomenon in question in terms of the metaphor “ ought is is ”; with “ ought ” as the more abstract target domain and “ is ” as the more concrete, cognitively simpler source domain. Secondly, the theory of speech act metonymy by Panther and Thornburg which presents descriptive legal sentences as referring to various components of the underlying cognitive scenario of obligation. Thirdly, Ronald Langacker’s notion of the virtuality of language as the explanation for non-present, including future, perpetual and directive, uses of the present tense. Fourtly, the notion of normative generics which points to the nominal, as opposed to verbal, structure of descriptive legal sentences as the source of their normativity. (shrink)

We present here some Boolean connexive logics (BCLs) that are intended to be connexive counterparts of selected Epstein’s content relationship logics (CRLs). The main motivation for analyzing such logics is to explain the notion of connexivity by means of the notion of content relationship. The article consists of two parts. In the first one, we focus on the syntactic analysis by means of axiomatic systems. The starting point for our syntactic considerations will be the smallest BCL and the smallest CRL. (...) In the first part, we also identify axioms of Epstein’s logics that, together with the connexive principles, lead to contradiction. Moreover, we present some principles that will be equivalent to the connexive theses, but not to the content connexive theses we will propose. In the second part, we focus on the semantic analysis provided by relating- and set-assignment models. We define sound and complete relating semantics for all tested systems. We also indicate alternative relating models for the smallest BCL, which are not alternative models of the connexive counterparts of the considered CRLs. We provide a set-assignment semantics for some BCLs, giving thus a natural formalization of the content relationship understood either as content sharing or as content inclusion. (shrink)

The purpose of this essay is to present and analyse the basic assumptions of Leszek Nowak’s conception of the unity of science. According to Nowak, the unity of science is manifested in the common application of the method of idealisation in scientific research. In accordance with his conception, regardless of the discipline they represent, researchers go through the same stages in building a theory. Two key ones among them are: introducing idealising assumptions into the representation and then their concretisation. In (...) this view, idealisation is the basis of the scientific method, while other cognitive procedures complement it. Nowak’s conception has particular relevance in the context of the dispute between naturalism and anti-naturalism and in the context of the continuing rift between social scientists and natural scientists. It calls into question the anti-naturalist thesis of the ontological uniqueness of social sciences and the resulting methodological consequences. I argue that Nowak’s conception is a cognitively valuable contribution to the contemporary epistemology of science, but it also has weaknesses, mainly due to the limitations of applying the idealisation-concretisation scheme in research practice. For it turns out, as I point out in this essay, that many idealising assumptions are not subject to concretisation and that concretisations do not always condition an increase in the explanatory and/or predictive power of the representations.

Celem artykułu jest prezentacja i krytyczna analiza koncepcji uczuć egzystencjalnych, autorstwa współczesnego filozofa psychiatrii o orientacji fenomenologicznej — Matthew Ratcliffe’a. Uczucia egzystencjalne są specjalną klasą stanów afektywnych, nadającą emocjonalnego zabarwienia subiektywnemu doświadczeniu rzeczywistości. Mają one charakter przedrefleksyjny i stanowią niejawne tło świadomości fenomenalnej, które w potocznym doświadczeniu pozostaje poza polem uwagi. Uczucia te mają ścisły związek z emocjami, determinując typy przedmiotów intencjonalnych zawartych w stanach emocjonalnych i wyznaczając repertuar możliwych do doświadczenia emocji. Najważniejsze uczucia egzystencjalne, które wyróżnia Ratcliffe, to: (1) (...) poczucie rzeczywistości, czyli przedrefleksyjne i fenomenalne wrażenie o realnym istnieniu świata jako takiego; (2) poczucie przynależności, czyli przedrefleksyjne i fenomenalne wrażenie własnego istnienia i osadzenia w świecie pośród osób i rzeczy. Te dwie kategorie stanowią fundamentalne składowe pierwszoosobowego doświadczenia podmiotu, wyznaczając tym samym jego relację do innych ludzi oraz rzeczywistości w jej najbardziej ogólnym sensie. W artykule przedstawiam główne cechy i typy uczuć egzystencjalnych. Zwracam także uwagę na szczególną rolę psychopatologii w analizie i uzasadnianiu istnienia tego zjawiska. W związku z tym, za Ratcliffem, opisuję w jaki sposób określone aspekty uczuć egzystencjalnych ulegają dezintegracji w przebiegu epizodów zaburzeń psychicznych, takich jak depresja czy schizofrenia. Pokazuję także różnicę pomiędzy fenomenologicznym i poznawczo-behoawioralnym podejściem do zaburzeń psychicznych. Powołując się na badania neurobiologiczne staram się wskazać potencjalne neuronalne korelaty uczuć egzystencjalnych. Tekst wieńczą krytyczne uwagi na temat koncepcji uczuć egzystencjalnych w ujęciu Matthew Ratcliffe’a. Rozwiązanie zidentyfikowanych wad i niedociągnięć tej teorii filozoficznej zarazem nakreśla przyszłe perspektywy jej rozwoju. (shrink)

James (1890) distinguished two understandings of the self, the self as “Me” and the self as “I”. This distinction has recently regained popularity in cognitive science, especially in the context of experimental studies on the underpinnings of the phenomenal self. The goal of this paper is to take a step back from cognitive science and attempt to precisely distinguish between “Me” and “I” in the context of consciousness. This distinction was originally based on the idea that the former (“Me”) corresponds (...) to the self as an object of experience (self as object), while the latter (“I”) reflects the self as a subject of experience (self as subject). I will argue that in most of the cases (arguably all) this distinction maps onto the distinction between the phenomenal self (reflecting self-related content of consciousness) and the metaphysical self (representing the problem of subjectivity of all conscious experience), and as such these two issues should be investigated separately using fundamentally different methodologies. Moreover, by referring to Metzinger’s (2018) theory of phenomenal self-models, I will argue that what is usually investigated as the phenomenal-“I” [following understanding of self-as-subject introduced by Wittgenstein (1958) ] can be interpreted as object, rather than subject of experience, and as such can be understood as an element of the hierarchical structure of the phenomenal self-model. This understanding relates to recent predictive coding and free energy theories of the self and bodily self discussed in cognitive neuroscience and philosophy. (shrink)

In this article we investigate the relationship between legal translation and legal interpretation. The common wisdom is that these activities are closely related, but the nature of that relationship remains disputable. We adopt the perspective of legal theory—as opposed to the perspective of translation studies—which seems to be underrepresented in the literature of the subject. We start with distinguishing between the two notions of legal interpretation: the wide sense and the narrow sense. We argue that the relationship between legal translation (...) and legal interpretation changes significantly depending on the notion of legal interpretation that is assumed. The wide sense is often assumed by translation scholars and it renders legal interpretation as a necessary prerequisite for legal translation. Jurists, on the other hand, usually assume the narrow sense which renders legal interpretation and legal translation as two distinct activities with some shared features. We then focus on four issues of legal interpretation in the narrow sense: the types of legal interpretive problems, the creation of legal interpretive problems, the methods of legal interpretation, the resolution of legal interpretive problems. We conclude with a detailed comparison of legal translation and legal interpretation in the context of those four issues. (shrink)

Preview: It is not a gross exaggeration to state that philosophy is an inherently urban phenomenon. Born and largely practiced in the Greek polis, it was developed throughout the ages in various places that more often than not were situated within city walls. Even if, udoubtedly, philosophy has never been limited solely to urban spaces, it has become more and more embedded in cities over the centuries. Consequently, from the 19th century on it has been part and parcel of the (...) intellectual life whose main centers have been towns since it has been almost exclusively researched on and taught within academic institutions.

The cognitive foundations of geometry have puzzled academics for a long time, and even today are mostly unknown to many scholars, including mathematical cognition researchers. -/- Foundations of Geometric Cognition shows that basic geometric skills are deeply hardwired in the visuospatial cognitive capacities of our brains, namely spatial navigation and object recognition. These capacities, shared with non-human animals and appearing in early stages of the human ontogeny, cannot, however, fully explain a uniquely human form of geometric cognition. In the book, (...) Hohol argues that Euclidean geometry would not be possible without the human capacity to create and use abstract concepts, demonstrating how language and diagrams provide cognitive scaffolding for abstract geometric thinking, within a context of a Euclidean system of thought. -/- Taking an interdisciplinary approach and drawing on research from diverse fields including psychology, cognitive science, and mathematics, this book is a must-read for cognitive psychologists and cognitive scientists of mathematics, alongside anyone interested in mathematical education or the philosophical and historical aspects of geometry.

Background: The number of cancer patients is constantly growing. Both WHO and IARC report that this number may reach up to 24 million new diagnosed cases in the next two decades. The proposed treatment and especially the diagnosis can have a significant impact on an individual's approach to the disease, as well as on the patient's quality of life.Objectives: The study aimed to assess the quality of life, feelings, and fear of cancer-treating oncological patients, before and during the COVID-19 pandemic.Material (...) and Methods: The study used the standardized WHOQOL quality of life questionnaire in a shortened version, the COVID-19 fear scale, and the AIS disease acceptance scale. The questionnaire survey was conducted among patients of cancer clinics. The study was conducted in two stages–before the COVID-19 pandemic and during the COVID-19 pandemic. Data from 450 correctly completed questionnaires were analyzed statistically. The obtained data were statistically processed using the Kruskal-Wallis and Mann-Whitney U test.Results: Among the surveyed patients of the cancer clinic, the quality of life during the COVID-19 pandemic decreased by 2%, compared to the period before the pandemic. The frequency of negative feelings associated with cancer increased during the COVID-19 pandemic–by 11% more men, and 4.4% of women determined the frequency of negative feelings to be 2–3 times a week. The level of fear associated with COVID-19 was moderate, with women having a higher level of fear.Conclusion: The development of the epidemic is very important in terms of public health. COVID-19 should be considered as one of the factors that bring about sudden changes in the mental health of the population, which may result from the dynamic development of this disease, dramatic media coverage, and own experiences. It has been shown that the sudden appearance of such a large stressor causes a decrease in patients' quality of life and an increase in negative feelings associated with chronic disease. (shrink)

IntroductionThe rapid development of technology has led to the transfer of entertainment to the virtual world. Many games and multimedia applications use the so-called augmented reality. With the development of a new technological branch, a new health problem has emerged, which is infoholic addiction, attracting people with the specific functionality that is cyberspace and the virtual world.ObjectiveThe study aimed to assess health behaviors and the risk of addiction among users of urban multimedia games. Research methodology. The study was conducted among (...) players 1,134 of urban multimedia games—Pokemon GO, in the period March–June 2021. A 990 correctly completed questionnaires were included in the final analyses. The author’s questionnaire was used in the study, which included two standardized measurement scales in the Polish abbreviated version: a questionnaire of emotions and sensations associated with electronic entertainment and a questionnaire on addiction to electronic forms of entertainment. Statistica 13.0 program was used for statistical processing of the data. The probability level was p < 0.05.ResultsThe profile of the gamer was identified as male, aged 18–30 years, with secondary education, not in a relationship, living in a city of more than 100 thousand inhabitants—60.1% of gamers met these criteria. Respondents played urban multimedia games daily. About 26.3% of respondents played this type of game 2–3 h a day. In terms of physical fitness, 64.3% of respondents felt that physical fitness had improved as a result of playing multimedia urban games. In terms of mental condition, most of the respondents said that nothing had changed. It was observed that 72.3% of respondents had some risk of addiction to urban multimedia games.ConclusionUsers of urban multimedia games were usually adult men living in big cities. It was also shown that the defined profile of the player was characterized by a higher risk of addiction to electronic forms of entertainment. It was observed that the respondents most often played urban multimedia games every day in a maximum of two-hour sessions. Based on the tools used, it can be concluded that the study group was characterized by a certain risk of addiction to urban multimedia games. (shrink)

It makes Bigaj’s (...) work an attractive handbook for the laymen as well as for professionals in other fields. (shrink)

The article demonstrates that to describe the property of atomicity of transactions in database systems, we need a three-valued logic with propositional connective characterized in the same way as Blamey’s interjunction.

The article introduces a logic of the considered kind, and provides an example of the formal exposition of the case (...) of an atomic transaction. Finally, the article explains the philosophical significance of the introduced logic. (shrink)

The aim of this article is to suggest that one should think of gardens in terms of performances and not necessarily in terms of architecture, painting, or poetry, for it is possible to show that, strangely enough, gardens seem to share certain features with performance arts. Such an approach seems fruitful since it allows one both to grasp the fact that gardens combine culture and nature and to underline the role of the latter, which cannot be reduced to a sheer (...) medium as is traditionally done. The contention is that gardens should be treated more like a continuous, dynamic, partly planned process in which people can participate in different ways on a par with other non-human ‘actors’. Moreover, the category of performance seems to offer a useful framework helping to solve certain problems inherent in traditional ways of thinking about gardens. (shrink)

In the following paper we propose a model-theoretical way of comparing the “strength” of various truth theories which are conservative over $$ PA $$. Let $${\mathfrak {Th}}$$ denote the class of models of $$ PA $$ which admit an expansion to a model of theory $${ Th}$$. We show (combining some well known results and original ideas) that $$\begin{aligned} {{\mathfrak {PA}}}\supset {\mathfrak {TB}}\supset {{\mathfrak {RS}}}\supset {\mathfrak {UTB}}\supseteq \mathfrak {CT^-}, \end{aligned}$$ where $${\mathfrak {PA}}$$ denotes simply the class of all models of (...) $$ PA $$ and $${\mathfrak {RS}}$$ denotes the class of recursively saturated models of $$ PA $$. Our main original result is that every model of $$ PA $$ which admits an expansion to a model of $$ CT ^-$$, admits also an expansion to a model of $$ UTB $$. Moreover, as a corollary to one of the results (brought to us by Carlo Nicolai) we conclude that $$ UTB $$ is not relatively interpretable in $$ TB $$, thus answering the question from Fujimoto (Bull Symb Log 16:305–344, 2010).

In my paper I undertake an attempt at an archaeological analysis of the increasing interest in emotions and affects in the humanities. Simultaneously, it is to some extent an attempt to continue Foucault's reflection from The Order of Things. In doing so, I reconstruct (a) previous ways – both philosophical and literary (starting from the seventeenth century) – of defining the relationship between “reason” and “heart” and (b) the origins, transformations and disintegration of the subject of desire. “Affectology” itself turns (...) out to be the result of (i) the decay of the traditional humanities (ii) the influence of structuralism, (iii) the emergence of “culture” which has replaced “human” as the primary reference point of the humanities.
