The article concerns two axiom systems of Słupecki for the functionally complete three-valued propositional logic: W1–W6 and A1–A9. The article proves that both of them are inadequate—W1–W6 is semantically incomplete, on the other hand, A1–A9 governs a functionally incomplete calculus, and thus, it cannot be a semantically complete axiom system for the functionally complete three-valued logic.

A method of constructing Hilbert-type axiom systems for standard many-valued propositional logics was offered by Rosser and Turquette. Although this method is considered to be a solution of the problem of axiomatisability of a wide class of many-valued logics, the article demonstrates that it fails to produce adequate axiom systems. The article concerns finitely many-valued propositional logics of Łukasiewicz. It proves that if standard propositional connectives of the Rosser–Turquette axiom systems are definable in terms of the propositional connectives of Łukasiewicz’s (...) logics, and thus, they are normal ones, then every Rosser–Turquette axiom system for a finite-valued Łukasiewicz’s logic is semantically incomplete.

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. However, the article explains that since Blamey’s partial logic with interjunction is a logic without tautologies, it does not satisfy some salient conditions of being a logic of atomic transactions. 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)

This book presents the heritage of the Lvov-Warsaw School from both the historical and the philosophical perspective. The historical view focuses on the beginnings and the dramatic end of the School brought about by the outbreak of World War II. The philosophical view, on the other hand, encompasses a broad spectrum of issues, including logical, epistemological, axiological, and psychological problems, revealing the interdisciplinary nature of studies carried out by Kazimierz Twardowski and his students. With thirteen diverse and original essays this (...) volume is split into three parts: History, Culture and Axiology; Psychology; and Logic and Methodology. Exploring not only the history of philosophy represented by the Lvov-Warsaw school, the book also reflects on the condition of contemporary philosophy from the perspective of concepts developed by its representatives. Furthermore, the studies presented in this book delve into problems of contemporary science and its distinctive interdisciplinary character. This volume is, therefore, not only a collection of analyses of the Lvov-Warsaw School philosophy, but also an investigation into the interdisciplinarity of science and philosophy itself. (shrink)

Replicability and reproducibility of computational models has been somewhat understudied by “the replication movement.” In this paper, we draw on methodological studies into the replicability of psychological experiments and on the mechanistic account of explanation to analyze the functions of model replications and model reproductions in computational neuroscience. We contend that model replicability, or independent researchers' ability to obtain the same output using original code and data, and model reproducibility, or independent researchers' ability to recreate a model without original code, (...) serve different functions and fail for different reasons. This means that measures designed to improve model replicability may not enhance (and, in some cases, may actually damage) model reproducibility. We claim that although both are undesirable, low model reproducibility poses more of a threat to long-term scientific progress than low model replicability. In our opinion, low model reproducibility stems mostly from authors' omitting to provide crucial information in scientific papers and we stress that sharing all computer code and data is not a solution. Reports of computational studies should remain selective and include all and only relevant bits of code. (shrink)

Artykuł jest próbą analizy koncepcji minimalistycznej neurofilozofii autorstwa Henrika Waltera w kontekście dyskusji dotyczącej problemu psychofizycznego. Bezpośrednio związana z ową koncepcją teoria o „zróżnicowanej metafizyce” została w tekście powiązana z ideą pluralizmu eksplanacyjnego i ukazana jako metodologiczna alternatywa dla poszukiwania fundamentalnych teorii świadomości. Jednocześnie poza ewentualnymi zaletami metafilozoficznej refleksji podejmowanej w ramach minimalistycznej neurofilozofii zarysowane zostały jej podstawowe ograniczenia i problemy związane m.in. z uznaniem superweniencji za punkt łączący różnorodne stanowiska neurofilozoficzne.

Oikologia to nauka o domu rozumianym szeroko, w kontekście dialektyki zakorzenienia człowieka w świecie, jako relacja zachodząca między nim a otaczającą go rzeczywistością. Dotyka w swojej analizie m.in. pytań z zakresu etyki środowiska dotyczących ludzkiej ingerencji w strukturę świata i stara się wspierać refleksję i wynikającą z niej postawę pełną wrażliwości na związek człowieka ze środowiskiem. Ekofilozofia, jako dyscyplina podejmująca wieloaspektową problematykę ochrony środowiska z perspektywy filozoficznej refleksji, w centrum zainteresowania stawia również badanie samej relacji łączącej człowieka ze środowiskiem przyrodniczym. (...) Celem artykułu jest wskazanie, iż refleksja oikologiczna może okazać się pomocną perspektywą dla szeroko pojętej ekofilozofii, a więc właśnie dla rozważań skupiających się na odpowiednim ułożeniu wspomnianej interakcji. Przykładem praktycznego problemu, w którym tego typu spojrzenie zostanie zaprezentowane, jest kwestia przestrzeni miejskiej, a konkretniej jej rewitalizacji, ze szczególnym naciskiem na obszary poprzemysłowe, którą w omawianym kontekście ekofilozofii wiąże się przede wszystkim z ideą zrównoważonego rozwoju.

In this paper it has been argued that the theory of conceptual maps developed recently by Paul M. Churchland provides support for Wittgenstein’s claim that language is a tool for acting in the world. The role of language is to coordinate and shape the conceptual maps of the members of the given language community, reducing the cross-individual cognitive idiosyncrasies and paving the way for joint cognitive enterprises. Moreover, Churchland’s theory also explains our tendency to speak of language as consisting of (...) concepts which correspond to things we encounter in the world. The puzzle of common sense reference is no longer a puzzle: while at the fundamental level language remains a tool for orchestrating conceptual maps, the fact that the maps encode some communally shared categorization of experience fuels our talk of concepts capturing the essences of things, natural kinds, prototypes, etc. (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)

In this paper, we focus on the development of geometric cognition. We argue that to understand how geometric cognition has been constituted, one must appreciate not only individual cognitive factors, such as phylogenetically ancient and ontogenetically early core cognitive systems, but also the social history of the spread and use of cognitive artifacts. In particular, we show that the development of Greek mathematics, enshrined in Euclid’s Elements, was driven by the use of two tightly intertwined cognitive artifacts: the use of (...) lettered diagrams; and the creation of linguistic formulae. Together, these artifacts formed the professional language of geometry. In this respect, the case of Greek geometry clearly shows that explanations of geometric reasoning have to go beyond the confines of methodological individualism to account for how the distributed practice of artifact use has stabilized over time. This practice, as we suggest, has also contributed heavily to the understanding of what mathematical proof is; classically, it has been assumed that proofs are not merely deductively correct but also remain invariant over various individuals sharing the same cognitive practice. Cognitive artifacts in Greek geometry constrained the repertoire of admissible inferential operations, which made these proofs inter-subjectively testable and compelling. By focusing on the cognitive operations on artifacts, we also stress that mental mechanisms that contribute to these operations are still poorly understood, in contrast to those mechanisms which drive symbolic logical inference.

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.

In consequence of significant social, political, economic, and demographic changes several wildlife species are currently growing in numbers and recolonizing Europe. While this is rightly hailed as a success of the environmental movement, the return of wildlife brings its own issues. As the animals arrive in the places we inhabit, we are learning anew that life with wild nature is not easy, especially when the accumulated cultural knowledge and experience pertaining to such coexistence have been all but lost. This book (...) provides a hermeneutic study of the ways we come to understand the troubling impacts of wildlife by exploring and critically discussing the meanings of 'ecological discomforts'. Thus, it begins the work of rebuilding the culture of coexistence. The cases presented in this book range from crocodile attacks to mice infestations, and their analysis consequently builds up an ethics that sees wildlife as active participants in the shaping of human moral and existential reality. This book is of interest not only to environmental philosophers, who will find here an original contribution to the established ethical discussions, but also to wildlife managers, and even to those members of the public who themselves struggle to make sense of encounters with their new wild neighbors.

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)

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)

Idea słowiańska” jest terminem ogólnym, odnoszącym się do wielu politycznych, historiozoficznych i kulturowych wątków, dla których inspiracją było językowe i kulturowe pokrewieństwo między narodami słowiańskimi. Takie ruchy jak słowianofilstwo i panslawizm miały na celu kulturalne i polityczne zjednoczenie Słowian. Idea ta wywarła silny wpływ na muzykę krajów środkowej i wschodniej Europy w XIX i XX wieku. Pod jej wpływem powstała znaczna liczba utworów muzycznych. Można utwory te podzielić na kilka grup. W jednych „słowiańskość” podkreślana była poprzez tytuł. Kompozytorzy używali również (...) typowo słowiańskich gatunków tanecznych i pieśniowych, jak polski mazurek i ukraińska dumka. Innym sposobem realizacji idei słowiańskiej były muzyczne kontakty między twórcami. Idea muzyki słowiańskiej pojawia się również w komentarzach muzykologicznych: słowiański „charakter” muzyczny bywał najczęściej łączony ze specyficznymi kategoriami emocjonalnymi, takimi jak smutek, tęsknota, szczególnie zaś żal, które to określenie stosowano do opisu przemożnego nastroju panującego w dziełach Chopina.

This paper is a follow-up to [4], in which a mistake in [6] 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${$, denoted by PT−in [9]). We show that if to PT−the axiom of internal induction forallarithmetical formulae is added, then this theory is semantically stronger than${\rm{P}}{{\rm{T}}^ - } + {\rm{INT}}\left$. In particular the latter is not relatively truth definable 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 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.

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$\mathrm {CT}_0$.

The author undertakes an attempt to present the philosophical and legal concepts comprising the legacy of a German theoretician of law, Gustav Radbruch, in respect of justice. The historical context for Radbruch is World War II, which forced German lawyers to face the question of the limits to which positive law is binding. Radbruch’s theory makes a breach in the legal positivism current of German legal reflection and thus belongs to what is known as the third way, setting out new (...) prospects in the history of the philosophy of law. The thread described by the author is the manner in which Radbruch connects natural law with legal positivism, demonstrating that, within a legal reality, they may exist in parallel. (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)

The subject embodied in the designed environment. Analysis of the use of the affordance concept in architecture: James Gibson’s ecological psychology is considered as one of the research subtraditions within embodied cognition. Gibson emphasizes the nature of the agent-environment interaction through the development of the theory of affordances. According to this idea, affordances are relational properties of the environment that enable a specific action for the agent. Currently this concept is being applied in many different contexts. This paper considers the (...) application potential of affordance in architectural studies as a tool that analyses the agent’s interaction with the environment. In this context, the affordance category can be a tool that allows one to take into account the importance of space for the shaping of behavior and interactions between its users, without falling into architectural determinism. The main aim of this study is to analyze affordances as a category that, despite its diversity and vagueness, can play an important role in the embodied view of architecture. The first part of the article is an attempt to synthetically place affordances in the context of embodied cognition and to point out the basic philosophical interpretations and discussions related to Gibson’s concept. In the next part, we situate the concept of affordances in the context of design practice. We also present the pros and cons of applying affordances to this ground. The last section in presenting the concept of affordances is considered within the background of the embodied current in architecture. (shrink)

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)

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 modeling of the human mind based on quantum effects has been gaining considerable interest due to the intriguing possibility of applying non-local interactions in the studies of consciousness. Inasmuch as the majority of the pertinent studies are restricted to the exclusive analysis of mental phenomena, the quantum model of mind proposed by Roger Penrose constitutes a part of a much larger scheme of the ultimate unification of physics. Penrose's efforts to find the 'missing science of consciousness' presuppose the non-algorithmic (...) character of human thinking inferred from Gödel's incompleteness theorem. This is supposed to combine with the anticipated non-algorithmic character of the future quantum gravity theory involving the objective reduction of a quantum mechanical state vector. By surveying contemporary achievements of cognitive sciences as well as the development of Penrose's conjectures, presented in his recent work The Road to Reality, we wish to show that his non-algorithmic quantum model of human mind is contingent upon the fundamental philosophical assumption of the mathematicity of the Universe.

The aim of the article is to analyze the relationship between Singapore and the People’s Republic of China in the light of the current policy of the President of the United States Donald Trump. The point of reference for the presented analysis is the foreign policy of the former President Barack Obama, based on the strategy known as “pivot to Asia” – the strategic turnabout of the United States to the Asia-Pacific region. One of its main objectives was the signing (...) of a multilateral agreement on the establishment of a free trade zone, the Trans-Pacific Partnership (TPP), bringing together 12 countries. The main subject of the present analysis is to examine the impact of Donald Trump’s decision of January 2017 to withdraw from the TPP trade agreement on the relations between the remaining signatories of the agreement, as well as to examine Beijing’s actions, which may seek to increase its sphere of influence in Asia through the breakdown of TPP. The main part of the research is focused on the triangle politics concept in international politics, which will include China, Singapore and the United States. Besides the two largest economic powers, Singapore is included because of its membership in the TPP and ASEAN, and due to its strong economy and its population (predominantly) of Chinese origin it can be viewed as the “fifth column” or may otherwise play a role in the Greater China concept.

Aphasia is an acquired impairment of language functions resulting from a brain lesion. It is usually accompanied by deficits in non-linguistic cognitive processes. This study aimed to investigate in patients with aphasia the complex interrelationships between selected cognitive functions: auditory speech comprehension, working memory, and temporal information processing in the millisecond time range. Thirty right-handed subjects aged from 27 to 82 years suffering from post-stroke aphasia participated in the study. Verbal working memory and spatial working memory were assessed with: a (...) receptive verbal test and the Corsi Block-Tapping Test, respectively. Both these WM tests used the forward tasks and backward tasks. Auditory comprehension was assessed by receptive language tests, and TIP efficiency was assessed by auditory perception of temporal order in the millisecond time range. We observed better performance of forward WM tasks than backward ones, independently of the type of material used. Furthermore, the severity of auditory comprehension impairment correlated with the efficiency on both forward and backward VWM tasks and the backward SWM task. Further analysis revealed that TIP plays a crucial role only in the latter task. These results indicate the divergent pattern of interactions between WM and TIP depending on the type of WM tasks. Level of verbal competency appeared to play an important role in both VWM tasks, whereas TIP appeared to be important for SWM, but only on the backward task. (shrink)

In 1890 William James 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 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) 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 from cognitive neuroscience and philosophy. (shrink)

The article describes areas of interpersonal communication in which the Virtual Reality technology plays an increasingly bigger role. The analysis of data shows that the VR system has proved successful in entertainment brand and is widely used for educational purposes. What is more brand advertising strategy can also rely on it. Access to virtual reality is still exclusive due to high price of the VR googles. However, more and more companies see a great potential of VR systems and increase funding (...) in order to develop this sector of technology. Interpersonal communication methodologies are always generation-based and thus one can suspect that the VR will became the main facility that connects people in the future. (shrink)

Recent increases in inflation rates around the world has lead to many discussions on the causes of such rapid adjustments, some suggesting that higher profits are responsible driving force behind inflation. Here we will focus on the United States case and demonstrate why quantity theory of money is relevant to explain what has been going on with inflation after 2020 rather than profit based theory of inflation. First section introduces the argument. Second section restates quantity theory of money with relevance (...) to the empirical literature. Third section shows why quantity theory despite some suggestions works to explain the current levels of inflation. Fourth section notices why increases in nominal profits during inflation are part of the natural adjustment path. Last section offers concluding comments. (shrink)
