Ageing populations are a major consideration for socio-economic development in the early twenty first century. This demographic change is mainly seen as a threat rather than as an opportunity to improve the quality of human life, especially in Europe, where ageing has resulted in a reduction in economic competitiveness. Economic Foundations for Creative Ageing Policy mixes the silver economy, the creative economy, and the social economy to construct positive solutions for an ageing population. Klimczuk covers theoretical analyses and case study (...) descriptions of good practices to suggest strategies that could be internationally popularized. Contents: Foreword by Harry R.

We provide to readers the 11th volume of the "Czech-Polish-Slovak Studies in Andragogy and Social Gerontology" series. We are delighted to announce that the presented study is the result of the work of scientists from seven countries: Austria, China, Ghana, Hungary, Japan, Poland, and Russia. This international collection of texts is part of the global discourse on the determinants of adult education and the functioning of people in late adulthood. The 11th volume is a collection of research results that show (...) both the positive and negative dimensions of ageing through the prism of research experience from various geographical and cultural areas. The researchers invited to the presented volume tried to illustrate the issues assigned to the following topics: ageing with dignity; retirement age; assumptions and conditions resulting from living in the home; the relationship between challenges concerning life expectancy and needs; care and ageing services; and foundations and potential changes in pension systems. The research results presented in this volume have a common denominator, which is caring for the quality of life of the older people regardless of their place of residence. Thus, the study "Between Successful and Unsuccessful Ageing: Selected Aspects and Contexts" brings new insights from scientists who scrupulously characterize the complexity of processes that affect the positive and negative conditions of functioning in old age, which is a mosaic of various nuances. Inviting readers to familiarize themselves with the content of the monograph, we would like to thank the reviewers who contributed to the improvement of the quality of the texts and open new fields for participation in further joint publishing projects.

This paper defends the Blockian Proviso against its critics, Kinsella in particular, and interprets it as a law of non-contradiction in the theory of just property rights. I demonstrate that one may not lawfully appropriate in such a way as to forestall others from appropriating an unowned land because such appropriation would result in conflict-generating norms, and conflict-generating norms are not rationally justifiable and just norms. The Blockian Proviso, which precludes forestalling, operates therefore at the level of original appropriation and (...) determines, according to the homestead principle of justice in first acquisition, what may and what may not be lawfully appropriated. Hence, the Blockian Proviso is not an add-on to the homestead principle but part and parcel thereof. (shrink)

Modern technology offers an increasing number of tools for teaching mathematics, but technology adoption in schools encounters many barriers. The Technology Acceptance Model explains that technology usage is dependent on intentions, which rest on perceived ease of use and perceived usefulness. Less is known about the relationship between intentions and actual behaviour. In the current study we show that the level of cognitive investment on the part of the teachers, captured by the construct of Need for Cognition (NC), is crucial (...) in the use of technology in mathematical instruction, while controlling for a variety of background factors. Furthermore NC moderates the relationship between intentions and technology use, such that high NC weakens the relationship between the perceived usefulness of technology in pedagogy and its actual use.

Can ownership status influence probability judgements under condition of uncertainty? In three experiments, we presented our participants with a recording of a real horse race. We endowed half of our sample with a wager on a single horse to win the race, and the other half with money to spend to acquire the same wager. Across three large studies, we found the endowment effect – owners demanded significantly more for the wager than buyers were willing to pay to acquire it. (...) However, we also found that probability estimates of each horse winning the race did not differ between owners and non-owners of the betting slip. Our results demonstrate that distorted perception of probability is unlikely to be a mechanism explaining the endowment effect. (shrink)

Do physicists believe that general relativity is true, and that electrons and phonons exist, and if so, in what sense? To what extent does the spectrum of positions among physicists correspond to philosophical positions like scientific realism, instrumentalism, or perspectivism? Does agreement with these positions correlate with demographic factors, and are realist physicists more likely to support research projects purely aimed at increasing knowledge? We conducted a questionnaire study to scrutinize the philosophical stances of physicists. We received responses from 384 (...) physicists and 151 philosophers. Our main findings are (1) On average, physicists tend toward scientific realism, and slightly more so than philosophers of science. (2) Physicists can be clustered into five groups. Three show variants of scientific realism, one is instrumentalist, and one seems undecided or incoherent. (3) Agreement with realism weakly correlates with approval of building a bigger particle collider. (4) Agreement with realism weakly correlates with the seniority of physicists. (5) We did not find correlations with other factors, such as whether physicists focus on theoretical or experimental research and whether they engage with applied or basic research. (shrink)

In this commentary, I critically assess Rex Welshon’s position on the neural substrates of ownership unity. First, I comment on Welshon’s definition of ownership unity and underline some of the problems stemming from his phenomenological analysis. Second, I analyze Welshon’s proposal to establish a mechanistic relation between neural substrates and ownership unity. I show that it is insufficient and defend my own position on how neural mechanisms may give rise to whole subjects of experience, which I call the neuro-integrative account (...) of consciousness. Lastly, I comment on Welshon’s philosophical contribution and claim that it leaves the reader theoretically stranded. (shrink)

According to contemporary understanding of the universal tree of life, the traditionally recognized kingdoms of eukaryotic organisms—Protista, Fungi, Animalia and Plantae—are irregularly interspersed in a vast phylogenetic tree. There are numerous groups that in any Linnaean classification advised by phylogenetic relationships would form sister groups to those kingdoms, therefore requiring us to admit them the same rank. In practice, this would lead to the creation of ca. 25-30 new kingdoms that would now be listed among animals and plants as “major (...) types of life”. This poses problems of an aesthetic and educational nature. There are, broadly speaking, two ways to deal with that issue: a) ignore the aesthetic and educational arguments and propose classification systems that are fully consistent with the Hennigian principles of phylogenetic classification, i.e. are only composed of monophyletic taxa; b) ignore Hennigian principles and bunch small, relatively uncharacteristic groups into paraphyletic taxa, creating systems that are more convenient. In the paper, I present the debate and analyze the pros and cons of both options, briefly commenting on the deeper, third resolution, which would be to abandon classification systems entirely. Recent advances in eukaryotic classification and phylogeny are commented in the light of the philosophical question of the purpose and design principles of biological classification systems.

The aim of the paper is to present two natural deduction systems for Intuitionistic Sentential Calculus with Identity ( ISCI ); a syntactically motivated \(\mathsf {ND}^1_{\mathsf {ISCI}}\) and a semantically motivated \(\mathsf {ND}^2_{\mathsf {ISCI}}\). The formulation of \(\mathsf {ND}^1_{\mathsf {ISCI}}\) is based on the axiomatic formulation of ISCI. Its rules cannot be straightforwardly classified as introduction or elimination rules; ISCI -specific rules are based on axioms characterizing the identity connective. The system does not enjoy the standard subformula property, but due (...) to the normalization procedure non-subformulas can label only leaves of proofs. In \(\mathsf {ND}^2_{\mathsf {ISCI}}\), we propose only two general identity-related rules, in reference to the treatment of the identity connective in First-Order Logic. (shrink)

Abstract.We present the results of research carried out as a part of the project Current Controversies about Human Origins: Between Anthropology and the Bible, which focused on the supposed conflict between natural sciences and some branches of the humanities, notably philosophy and theology, with regard to human origins. One way to tackle the issue was to distribute a questionnaire among students and teachers of the relevant disciplines. Teachers of religion and the natural sciences (biology, chemistry, and physics) and students of (...) theology, philosophy, and the natural sciences (specializing in biology and/or anthropology) were asked to answer eleven questions concerning the perception of the conflict between evolutionism and creationism, the definitions of creation and evolution, the existence of a human spiritual element, and the ways of interpreting the Bible, especially the first chapters of the book of Genesis. We present selected results of this questionnaire. (shrink)

The increasing popularity of artificial cognitive enhancements raises the issue of their impact on the agent’s personal autonomy, and issues pertaining to how the latter is to be secured. The extended mind thesis implies that mental states responsible for autonomous action can be partly constituted by the workings of cognitive artifacts themselves, and the question then arises of whether this commits one to embracing an extended agent thesis. My answer is negative. After briefly presenting the main accounts on the conditions (...) for autonomous agency, and analyzing how the latter can be protected from threats posed by the use of cognitive artifacts, I argue that autonomous agency is essentially tied to conscious experience and intentionality, which in turn can only be attributed to the human part of any extended cognitive system. I present both theoretical (conceptual) and practical arguments against recognizing the entire extended system, composed of one human and an artifact, as an autonomous agent. (shrink)

The paper presents the results of the research which was carried out as part of the project: Current controversies about human origins. Between anthropology and the Bible. This project focuses on the supposed conflict between natural sciences and some branches of the humanities (notably philosophy and theology) with regard to the origin of man. The research was aimed at finding out whether such a conflict really exits. For one thing, we cannot exclude the possibility that these would-be controversies have no (...) factual ground and that their significance is inflated by American popular literature. If, on the other hand, we assume that the conflict is real, it should be worthwhile examining its sources. Such an approach may prove helpful in systematising the highly emotional debates about the origin of man. One of the ways of tackling the issue was the questionnaire which was distributed among students, teachers and university professors. Our respondents represented three disciplines: theology, philosophy and the natural sciences, the paper will present selected results of the questionnaire which was addressed to a group of school teachers, whereas the responses of the students are given less attention in order to emphasise the teachers’ point of view, the teachers of religion and the natural sciences (biology, chemistry and physics) and the students of theology, philosophy and the natural sciences (specialising in biology and environment protection) were asked to fill in the form consisting of eleven questions, these questions concerned the following issues: the existence of the conflict between evolutionism and creationism, the definitions of creation and evolution, the existence of the spiritual element in man, ways of interpreting the Bible (esp. the first chapters of the Book of Genesis). Out of 1000 questionnaires sent out, we received 449, which should be considered a satisfactory number, given the fact that it was the first time this type of research was carried out in Poland.

One of the particular problems in the debate between science and theology regarding human origins seems to be an apparent controversy between the continuous character of evolutionary processes leading to the origin of Homo sapiens and the punctual understanding of the act of creation of man seen as taking place in a moment in time. The paper elaborates scientific arguments for continuity or discontinuity of evolution, and what follows, for the existence or nonexistence of a clear borderline between our species (...) and the rest of the living world. It is argued that, due to the conventional character of the notion of species, anthropology is unable to point to a moment in time or a place on Earth when or where Homo sapiens came into existence as a ‘really new’ species. The argument of the non˗specificity of humans is reinforced by considering emotional homologies between man and apes, “cultural” transmission of the patterns of behaviour in animals, or their mental and communicational abilities. All this is in line with a more general philosophical view of ontological continuity of the world. However, the argument is counterbalanced by pointing to such human characteristics as the ability to use abstract notions, or those forms of human behaviour which do not seem to have their animal analogues. In turn, various possibilities of theological interpretations of the act of creation of man are pointed out and a question is considered as to what extent theology is interested in a "momentary" account of this act. By pointing to theological accounts proposed as early as the 2nd century, it is argued that a vision of God – the craftsman who ‘builds’ its creation step by step, or even less restrictive forms of divine interventionism, are theologically inadequate. The original opposition between the continuity of evolutionary processes and ‘punctual’ character of creation is thus weakened and, from that perspective, a solution to the controversy in question is sought. One of such solutions, an “evolutionary model of creation”, a form of evolutionary creationism, proposed by a Polish philosopher Kazimierz Kloskowski, is presented. This model is based on two assumptions, stemming from process philosophy and evolutionary epistemology. The need to apply them in constructing a coherent view on evolution and creation is critically considered in the paper. (shrink)

BackgroundIn crisis communication, warning messages are key to informing and galvanizing the public to prevent or mitigate damage. Therefore, this study examines how risk appraisal and individual characteristics influence the intention to comply with behavioral recommendations of a warning message regarding three hazard types: the COVID-19 pandemic, violent acts, and severe weather.MethodsA cross-sectional survey examined 403 German participants from 18 to 89 years. Participants were allocated to one of three hazard types and presented with warning messages that were previously issued (...) via an official warning app. Four components of risk appraisal—perceived severity, anticipated negative emotions, anticipatory worry, and risk perception —were assessed before and after presenting the warning message. Path models were calculated to predict the intention to comply with the warning message, controlling for age, gender, and previous hazard experience.ResultsFor the COVID-19 pandemic, higher age predicted warning compliance. AE predicted compliance in the case of violent acts. For severe weather, PS, age, and female gender lead to higher compliance. Changes across risk appraisal components were not consistent, as some facets decreased after the receipt of a warning message.DiscussionRisk appraisal has shown a marginal yet differential influence on warning message compliance in different types of hazards. Regarding the COVID-19 pandemic, the impact of sociodemographic factors on compliance should be studied more intensively. Moreover, integrating intermediary variables, such as self-efficacy, is necessary. (shrink)

This article examines, in a comparative perspective, the integration policy of the two, in many respects, very similar, neutral states, with particular emphasis on the period after the signing of the Single European Act. Despite the converging political and economic objectives, the decisions of both countries were determined by different economic and political conditions. For Austria, the integration processes were perceived as an important step, towards reconstruction of the economy, the abolition of trade barriers with the most important economic partner. (...) In political terms integration – enhanced Austria’s position within European Community. Unlike the Austrian Government, the authorities in Bern have acted under much more polarized conditions. Neutrality played still very important role in its international policies and the social fears connected mostly to the loss of political and economic independence were vivid. The Swiss authorities were thus forced to choose the bilateral path, which was not preferred by EU countries, but more socially acceptable, and therefore easier to implement. (shrink)

Understanding emotions — an apparent contradiction. Comments on Andrzej Dąbrowski’s Origins, nature and functions of emotions: This paper offers some polemical comments on Andrzej Dąbrowski’s recently published book Origins, nature and functions of emotions. The background for reflection is Leon Petrażycki’s theory of emotions. The author aims to evaluate Dąbrowski’s presentation of an influential Polish philosopher Leon Petrażycki, considered an important forerunner of the psychosocial theory of law or legal psychologism, who initiated a long‐lasting debate on the role and meaning (...) of emotions.

One way to tackle the issue was to distribute a questionnaire among students and teachers of the relevant disciplines.

In the paper we present and analyze selected results of this questionnaire. Among interesting findings there are the following: 1) the opinion concerning the relationship between evolutionism and creationism largely depends on the respondent’s general attitude toward religion, and not on their field of study or teaching expertise, which runs contrary to the received view attributing the opinion of the conflict between science and religion to people’s educational or professional background; 2) The conflict is far more pronounced in the group of nonbelievers. This distinguishes Poland from other countries, notably the United States, where the majority of people with strong religious beliefs seem to maintain that there is a conflict between the natural sciences and religion; 3) literal understanding of the Bible was rejected by vast majority of the respondents, including those who insist on the ‘conflict view’, which seems to make the situation in Poland again quite different from that in some other countries; 4) Unsophisticated understanding of creation positively correlates with the ‘conflicting view’ on the one hand, while, on the other, erroneous understanding of the basics of the theory of evolution appears to have its bearing on too optimistic vision of certain coherence between religion and science. We suggest some hypotheses to explain these and other results of the questionnaire. (shrink)

This paper presents sample results from a poll conducted among experts regarding the roots of the controversy between the evolutionary account of human origin and religious convictions about creation. It appears that the position one takes in this controversy is influenced much more by one’s opinions than professional background. The controversy is usually only seemingly ‘solved’ at the level of a priori assumptions, erroneous definitions of ‘evolutionism’ and ‘creationism’, semantic viewpoints, epistemological positions and pragmatic choices. The core issues in the (...) controversy are widely neglected and do not play a significant role in deciding one’s views on the matter. -------------- Received: 28/08/2020. Reviewed: 30/09/2020.

Heated debates stemming from the confrontation of scientific knowledge with the biblical picture of the creation of man, which had followed the publication of Darwin's theory of evolution, became far less prominent in the second half of the 20th century. This was due to two factors: first, the theory of evolution was partly accepted in theological circles and at the same time biologists showed a growing awareness of the limited epistemological scope of the competence of the natural sciences. This lesson (...) from the history, however, seems to have been forgotten by many who now and again return to controversies which more often than not are caused by ideological quarrels over religion, with true scholarship being too easily lost from sight. The paper reminds some of the history of the controversy in question and suggests that at least some of the current problems regarding evolution˗and˗ creation controversy may have already found their solutions. In part 1, “The Theory of Evolution and the Creation of the Human” it deals with the general issue of human origins. In part 2, “Monogenism and Original Sin” it explores the notion of the ‘first human’ as it is employed in biology and in theology, and shows its completely different meaning in these two realms of knowledge which helps to resolve the recurrent controversy over monogenism.

This paper aims to determine whether extended human-machine cognitive systems and group systems can be regarded as autonomous agents. For this purpose, I compare two notions of agency: one developed within analytical philosophy of action and based on the concept of intention, and the other introduced by enactivists via the concepts of autopoiesis and sensorimotor autonomy. I argue that only the latter approach can be used to demonstrate autonomous agency in respect of systems that are not humans as such, though (...) they contain humans as their elements. After introducing Maturana and Varela’s conception of minimal autonomy as a kind of generalization of autopoiesis, I present the three conditions of agency put forward by Barandiaran, Di Paolo and Rohde, noting that they do not invoke the property of being alive as necessary in that respect. I argue that both extended and group systems can satisfy these conditions of agency, even though they are not alive as such. The fulfillment of these conditions, however, is ensured by the autopoietic nature of the living components of these systems. That being said, an autonomous system itself does not need to be alive in the biological sense. Sensorimotor, adaptive agency could emerge out of other processes than those responsible for biological life. The article concludes with a suggestion that this is exactly what will happen if an autonomous system is ever artificially created. It would be functionally indistinguishable from a living organism, though not alive in a biological sense. (shrink)

IntroductionSwitzerland lacks specific legal regulation of assistance in suicide. The practice has, however, developed since the 1980s as a consequence of a gap in the Swiss Criminal Code and is performed by private right-to-die organisations. Traditionally, assistance in suicide is considered contrary to the philosophy of palliative care. Nonetheless, Swiss palliative care physicians regularly receive patient requests for suicide assistance. Their attitudes towards the legal regulations of this practice and their experience in this context remain unclear.ObjectivesOur study aimed to explore (...) and describe the attitudes and experiences of Swiss palliative care physicians concerning the legal situation of suicide assistance.MethodsIn 2019, we performed an exploratory interview study with 12 Swiss palliative care physicians on palliative sedation as an alternative to assisted suicide. In this paper, we present the results that emerged from a thematic subanalysis of the data.ResultsParticipants stated that assistance in suicide and palliative care are based on opposing philosophies, but they admitted a shift in paradigm over the last years in the sense that one practice does not necessarily exclude the other. They reported various roles in suicide assistance and considered that the current activities of Swiss right-to-die organisations were problematic and needed to be regulated by law.Discussion and conclusionThese results could enrich national and international reflection on suicide assistance in the context of palliative care by reducing confusion between the two practices and strengthening the confidence of patients and their relatives.

IntroductionGratitude is commonly known as a positive emotion, but it can also be understood as a disposition—one’s inherent quality that includes being grateful for the positive aspects of one’s life and appreciating altruistic gifts. A growing body of research suggests that having a disposition of gratitude is positively related to wellbeing and psychological adjustment. The present study examined the extent to which acceptance of illness—a measure of adjustment to a distressing condition—mediated relationships between dispositional gratitude and wellbeing among women who (...) had elevated levels of depressive symptoms.MethodsParticipants were 131 women who, based on scores on the Center for Epidemiological Studies Depression scale, were at-risk for experiencing clinical depression. Thirty-five of these participants had been diagnosed as depressed at some point in their lives and 96 had not. Participants completed measures of dispositional gratitude, wellbeing, anxiety, and acceptance of illness.ResultsDispositional gratitude was positively correlated with wellbeing and was negatively correlated with depression and anxiety. Dispositional gratitude was also positively correlated with acceptance of illness. Mediational analyses found that acceptance of illness mediated relationships between dispositional gratitude and wellbeing, between dispositional gratitude and anxiety, and between dispositional gratitude and depression. Moreover, such mediation varied as a function of whether women had ever been diagnosed as depressed. Acceptance of illness was related more strongly to wellbeing for women who had been diagnosed as depressed at some time in their lives than it was for women who had never been diagnosed as depressed.ConclusionWomen with elevated depressive symptoms who were more grateful were more accepting of their condition, which was related to increased wellbeing and decreased feelings of depression and anxiety.

An interesting phenomenon of diffusion of borders is observed within current discussion on realism. Philosophers retreat from unequivocal positions; as the result, clarity of this discussion is impaired. This concerns as well the internal realism as some other positions, represented e.g. by van Fraassen, Feyerabend and by the Edinburgh School. The paper aims at showing that combining realistic and antirealistic theses in one philosophical position seems to be inevitable. These theses are becoming so similar that they can be interpreted in (...) realistic as well as antirealistic way, allowing their proponents to avoid inconsistencies. However, for the same reason discussion becomes somewhat pointless, and declaration "I am a scientific realist (or antirealist)" is no longer understandable. (shrink)

In recent years we may observe increasing interest in the development of social innovation both regarding theory as well as the practice of responding to social problems and challenges. One of the crucial challenges at the beginning of the 21st century is population ageing. Various new and innovative initiatives, programs, schemes, and projects to respond to negative consequences of this demographic process are emerging around the world. However, social theories related to ageing are still insufficiently combined with these new practices, (...) social movements, organisational models, and institutions. Many scholars are still using notions and tools from classical theories of social gerontology or the sociology of ageing such as disengagement theory, activity theory, and successful and productive ageing. Such theories do not sufficiently explain ageing in the context of, for example, a broad use of the information and communications technologies including robotics and automation, new healthcare and long-term care models, advancements in the development and governance of age-friendly environments, and public engagement of older adults into co-production of services delivered by public, private, non-governmental as well as non-formal entities.
