This paper answers the philosophical contentions defended in Horsten and Welch (2007, Synthese, 158, 41–60). It contains a description of the standard format of adaptive logics, analyses the notion of dynamic proof required by those logics, discusses the means to turn such proofs into demonstrations, and argues that, notwithstanding their formal complexity, adaptive logics are important because they explicate an abundance of reasoning forms that occur frequently, both in scientific contexts and in common sense contexts.

In this paper I present two new strategies for inconsistencyadaptive logics: the reliable sufficient information strategy of ACLuN3 andthe minimally abnormal sufficient information strategy of ACLuN4. I giveproof theory and semantics for both ACLuN3 and ACLuN4. I also compare them with the well-known inconsistency-adaptive logics ACLuN1 andACLuN2.

We consider the very weak paracomplete and paraconsistent logics that are obtained by a straightforward weakening of Classical Logic, as well as some of their maximal extensions that are a fragment of Classical Logic. We prove that these logics may be faithfully embedded in Classical Logic, and that the interpolation theorem obtains for them.

Presentism is the view that only present entities exist. Recently, several authors have asked the question whether presentism is able to account for cross-time relations, i.e., roughly, relations between entities existing at different times. In this paper I claim that this question is to be answered in the affirmative. To make this claim plausible, I consider four types of cross-time relation and show how each can be accommodated without difficulty within the metaphysical framework of presentism.

In this paper our aim is to examine whether research conducted on human participants with LSD-25 raises unique research ethical questions or demands particular concerns with regard to the design, conduct and follow-up of these studies, and should this be the case, explore and describe those issues. Our analysis is based on reviewing publications up to date which examine the clinical, research and other uses of LSD and those addressing ethical and methodological concerns of these applications, just as some historical (...) examinations of this subject. The first chapters of the paper give an overview regarding the history of LSD-research with human participants, healthy volunteers and patients alike. The remaining chapters have a focus on questions regarding the potential ethical issues of such human trials in the contemporary research ethics framework. We also consider briefly political and regulatory issues regarding this substance that possibly affect its clinical and research applications. (shrink)

We present the first comprehensive taxonomic revision and review the biology of the olingos, the endemic Neotropical procyonid genus Bassaricyon, based on most specimens available in museums, and with data derived from anatomy, morphometrics, mitochondrial and nuclear DNA, field observations, and geographic range modeling. Species of Bassaricyon are primarily forest-living, arboreal, nocturnal, frugivorous, and solitary, and have one young at a time. We demonstrate that four olingo species can be recognized, including a Central American species (Bassaricyon gabbii), lowland species with (...) eastern, cis-Andean (Bassaricyon alleni) and western, trans-Andean (Bassaricyon medius) distributions, and a species endemic to cloud forests in the Andes. The oldest evolutionary divergence in the genus is between this last species, endemic to the Andes of Colombia and Ecuador, and all other species, which occur in lower elevation habitats. Surprisingly, this Andean endemic species, which we call the Olinguito, has never been previously described; it represents a new species in the order Carnivora and is the smallest living member of the family Procyonidae. We report on the biology of this new species based on information from museum specimens, niche modeling, and fieldwork in western Ecuador, and describe four Olinguito subspecies based on morphological distinctions across different regions of the Northern Andes.

In this paper I argue that recent attempts at explaining aesthetic ineffability have been unsuccessful. Either they misrepresent what aesthetic ineffability consists in, or they leave important aspects of it unexplained. I then show how a more satisfying account might be developed, once a distinction is made between two kinds of awareness. -/- .

It has been argued (for example, by Nelson Goodman and John Hyman) that ‘depicts’ and similar terms such as ‘is a picture of’ and ‘represents’ are semantically ambiguous: sometimes they are two-place predicates expressing a relation, and sometimes they are not. This article takes issue with this claim and develops an alternative theory according to which the ambiguity in question is pragmatic rather than semantic.

Intertemporal choice involves deciding between smaller, sooner and larger, later rewards. People tend to prefer smaller rewards that are available earlier to larger rewards available later, a phenomenon referred to as temporal or delay discounting. Despite its ubiquity in human and non-human animals, temporal discounting is subject to considerable individual differences. Here, we provide a critical narrative review of this literature and make suggestions for future work. We conclude that temporal discounting is associated with key socio-economic and health-related variables. Regarding (...) personality, large-scale studies have found steeper temporal discounting to be associated with higher levels of self-reported impulsivity and extraversion; however, effect sizes are small. Temporal discounting correlates negatively with future-oriented cognitive styles and inhibitory control, again with small effect sizes. There are consistent associations between steeper temporal discounting and lower intelligence, with effect sizes exceeding those of personality or cognitive variables, although socio-demographic moderator variables may play a role. Neuroimaging evidence of brain structural and functional correlates is not yet consistent, neither with regard to areas nor directions of effects. Finally, following early candidate gene studies, recent Genome Wide Association Study (GWAS) approaches have revealed the molecular genetic architecture of temporal discounting to be more complex than initially thought. Overall, the study of individual differences in temporal discounting is a maturing field that has produced some replicable findings. Effect sizes are small-to-medium, necessitating future hypothesis-driven work that prioritizes large samples with adequate power calculations. More research is also needed regarding the neural origins of individual differences in temporal discounting as well as the mediating neural mechanisms of associations of temporal discounting with personality and cognitive variables.

As narrative conceptions of selfhood have gained more acceptance within various disciplines including philosophy, psychology, and the cognitive sciences, so too have these conceptions been critically appraised. Chief among those who are suspicious of the overall viability of ‘narrative identity’ is the philosopher, Galen Strawson. In this paper, I develop five arguments underlying Strawson’s critique of narrative identity, and respond to each argument from the perspective of the hermeneutic phenomenology of Paul Ricœur. Though intuitive, I demonstrate that none of Strawson’s (...) arguments are cogent. The confrontation between these two figures highlights a deep conceptual disagreement about our epistemic access to the self, which has thus far gone unrecognized in the Anglo-American discussion, so that it raises a new problem for the metaphysics of personal identity.

Stimulating innovation and growth in the so-called ‘creative economy’ is a current policy objective for national regulators. One policy lever traditionally applied to the creative sector is intellectual property, in particular the scope and term of protection offered by copyright. Opposition to expansion and further enclosure of the copyright public domain was previously articulated in terms of access to a commons of information. Since the Hargreaves Review of Intellectual Property in 2011, copyright reform in the UK context is increasingly framed (...) in the language of economics. This paper reviews two prevailing economic theories shaping how policy makers discuss the public domain in debates about IP reform: a welfare economics approach which weighs increases in producer and consumer surplus under different policy configurations and an economics of innovation approach which considers the value of the public domain as a reservoir of ideas for individuals and firms. I argue that economic definitions should be augmented by a consideration of the democratic requirement of access to information. The consequences of this re-figuration of the public domain for the public interest and access to information are discussed. (shrink)

Fairness in machine learning (ML) is an ever-growing field of research due to the manifold potential for harm from algorithmic discrimination. To prevent such harm, a large body of literature develops new approaches to quantify fairness. Here, we investigate how one can divert the quantification of fairness by describing a practice we call “fairness hacking” for the purpose of shrouding unfairness in algorithms. This impacts end-users who rely on learning algorithms, as well as the broader community interested in fair AI (...) practices. We introduce two different categories of fairness hacking in reference to the established concept of p-hacking. The first category, intra-metric fairness hacking, describes the misuse of a particular metric by adding or removing sensitive attributes from the analysis. In this context, countermeasures that have been developed to prevent or reduce p-hacking can be applied to similarly prevent or reduce fairness hacking. The second category of fairness hacking is inter-metric fairness hacking. Inter-metric fairness hacking is the search for a specific fair metric with given attributes. We argue that countermeasures to prevent or reduce inter-metric fairness hacking are still in their infancy. Finally, we demonstrate both types of fairness hacking using real datasets. Our paper intends to serve as a guidance for discussions within the fair ML community to prevent or reduce the misuse of fairness metrics, and thus reduce overall harm from ML applications. (shrink)

What if language was an autonomous historical being? What if language’s use was not solely dependent on the intentions of the one who speaks? In this text I will test these provocative statements. Specifically, I will investigate whether language’s proclaimed historical independence can be traced in the usage of the concept of ‘secularisation’, and I will try to unveil the consequences of this operation.Contribution: Has Christianity abandoned the public stage in the ‘secularised’ and industrialised world? In this article I intend (...) to demonstrate that this is not the case. The continuous operative presence of Christianity in our socio-political language is used as the model to prove this argument.

A number of philosophers attribute the underrepresentation of women in philosophy largely to bias against women or some kind of wrongful discrimination. They cite six sources of evidence to support their contention: (1) gender disparities that increase along the path from undergraduate student to full time faculty member; (2) anecdotal accounts of discrimination in philosophy; (3) research on gender bias in the evaluation of manuscripts, grants, and curricula vitae in other academic disciplines; (4) psychological research on implicit bias; (5) psychological (...) research on stereotype threat; and (6) the relatively small number of articles written from a feminist perspective in leading philosophy journals. In each case, we find that proponents of the discrimination hypothesis have tended to present evidence selectively. Occasionally they have even presented as evidence what appears to be something more dubious. (shrink)

Scholar of religion Karl Kerényi’s last book, Dionysos, is a grand attempt at reinterpreting ζωη ( zoe ), the Greek concept of indestructible life, which he distinguishes from βίος (bios), finite life. In Kerényi’s view, the meaning and sensual experience of zoe was expressed in its richest form in the Cretan beginnings of the cult of Dionysos. The major characteristics of this cult, as Kerényi describes, were beyond the cultural, political, and sexual limits of the Christian interpretations of life and (...) nature. Searching for modern analogies to zoe , Kerényi explains the idea in relation to molecular biology’s minimum definition of life. Despite the fact that Kerényi’s book contains only minor references to contemporary philosophy, the philosophical consequences of his interpretations of Dionysos are not only radical but outline a notion of biopolitics far in advance of the mid- to late 20 th -century development of it. By the affirmation of indestructible life and animality , Kerényi proposes a new humanism that moves beyond the limits of Kantian anthropology and also takes a radically different perspective to that of Heidegger’s philosophy of being, or Agamben’s notion of biopolitics. According to Kerényi’s investigations, since this alternative humanism, which is based on the radical recognition of the individuality and diversity of life forms, was once possible in an earlier stage of human culture, it is possible to reanimate it in order to shape anew how zoe is understood and therefore lived. Our relation to nature can thereby undergo a Dionysian transvaluation and assign us new responsibilities as well as open up a new trajectory for the 21 st -century human. (shrink)

BackgroundRich in different kind of potent cells, embryos are used in modern regenerative medicine and research. Neurobiologists today are pushing the boundaries for what can be done with embryos existing in the transitory margins of medicine. Therefore, there is a growing need to develop conceptual frameworks for interpreting the transformative cultural, biological and technical processes involving these aborted, donated and marginal embryos. This article is a contribution to this development of frameworks.MethodsThis article examines different emotional, cognitive and discursive strategies used (...) by neurobiologists in a foetal cell transplantation trial in Parkinson’s disease research, using cells harvested from aborted embryos. Two interviews were analysed in the light of former observations in the processing laboratories, using the anthropologist Mary Douglas’s concept of pollution behaviour and the linguist, philosopher, psychoanalyst and feminist Julia Kristeva’s concept of the abjective to explain and make sense of the findings.ResultsThe findings indicate that the labour performed by the researchers in the trial work involves transforming the foetal material practically, as well as culturally, from trash to treasure. The transformation process contains different phases, and in the interview material we observed that the foetal material or cells were considered objects, subjects or rejected as abject by the researchers handling them, depending on what phase of process or practice they referred to or had experience of. As demonstrated in the analysis, it is the human origin of the cell that makes it abjective and activates pollution discourse, when the researchers talk of their practice.ConclusionsThe marginal and ambiguous status of the embryo that emerges in the accounts turns the scientists handling foetal cells into liminal characters in modern medicine. Focusing on how practical as well as emotional and cultural strategies and rationalizations of the researchers emerge in interview accounts, this study adds insights on the rationale of practically procuring, transforming and utilizing the foetal material to the already existing studies focused on the donations. We also discuss why the use and refinement of a tissue, around which there is practical consensus but cultural ambiguity, deserves further investigation. (shrink)

Entrepreneurs with social goals face various challenges; insights into how these entrepreneurs experience and appreciate their work remain a black box though. Drawing on identity, conservation of resources, and person–organization fit theories, this study examines how entrepreneurs’ social value creation beliefs relate to their work-related well-being (job satisfaction, work engagement, and lack of work burnout), as well as how this process might be influenced by social concerns with respect to the common good. Using data from the German Public Value Atlas (...) 2015 and 2019 and the Swiss Public Value Atlas 2017, a three-study design analyzes three samples of entrepreneurs in Germany and Switzerland. Study 1 reveals that entrepreneurs report higher job satisfaction when they believe their organization creates social value. Study 2 indicates that these beliefs relate negatively to work burnout; entrepreneurs’ perceptions of having meaningful work mediate this relationship. Study 3 affirms and extends these results by showing that a sense of work meaningfulness mediates the relationship between social value creation beliefs and work engagement and that this mediating role is more prominent among entrepreneurs with strong social concerns. This investigation thus identifies a critical pathway—the extent to which entrepreneurs experience their work activities as important and personally meaningful—that connects social value creation beliefs with enhanced work-related well-being, as well as how this process might vary with a personal orientation that embraces the common good.

The study focuses on the ethical aspects of decision-making by national elites in the context of the thinking of Ján Kollár (1793–1852) and Ľudovít Štúr (1815–1856) on the issue of Slavism. Attention is paid to the issue of responsibility for preserving the greatness and unity of the nation in the context of the formation of national identity and individuality. The concepts of the mentioned authors had an impact on the cultural-civilizational orientation of Slovak elites with an emphasis on the role (...) of moral obligations in shaping the value orientation of the nation. In this context, the analysis focuses on the works Reciprocity between the various tribes and dialects of the Slavic nation and Slavdom and the world of the future, which, at the same time, represent alternative concepts of the cultural and political orientation of the Slavs. The study simultaneously analyses these concepts as alternative programs of cultural and political development of national identity, as well as concepts aimed at humanist and political goals.

Problems arise when applying the current procedural conceptualization of decision-making capacity to paediatric healthcare: Its emphasis on content-neutrality and rational cognition as well as its implicit assumption that capacity is an ability that resides within a person jeopardizes children’s position in decision-making. The purpose of the paper is to challenge this dominant account of capacity and provide an alternative for how capacity should be understood in paediatric care. First, the influence of developmental psychologist Jean Piaget upon the notion of capacity (...) is discussed, followed by an examination of Vygostky’s contextualist view on children’s development, which emphasizes social interactions and learning for decision-making capacity. In drawing parallels between autonomy and capacity, substantive approaches to relational autonomy are presented that underline the importance of the content of a decision. The authors then provide a relational reconceptualization of capacity that leads the focus away from the individual to include important social others such as parents and physicians. Within this new approach, the outcome of adults’ decision-making processes is accepted as a guiding factor for a good decision for the child. If the child makes a choice that is not approved by adults, the new conceptualization emphasizes mutual exchange and engagement by both parties. (shrink)

The dialectical-theological origins of the politically- and ethically-charged concept of alterity are well-known within the philosophy of religion. Intellectual histories of this concept tie it too exclusively to the notion of distance or διάστασις in Karl Barth’s early Römerbrief, however, and so miss Barth’s Trinitarian reinterpretation of God’s otherness in his later work. Taking as my hermeneutical key a cipher, the ‘sign of Jonah,’ that emerges in Church Dogmatics IV/1, I show that Barth’s mature doctrines of temporality and filiation understand (...) alterity as a moment of divine life. Jesus’ agony in the garden of Gethsemane marks the climax of Barth’s self-reinterpretation: world history inheres within the Christological situation of paternal abandonment. The political-theological conclusions Barth draws from the ‘sign of Jonah’ dovetail with alterity discourses’ antitotalitarian aspirations but suggest that these aspirations’ structural coherence rest on the magisterial Reformers’ Christological and ecclesiological commitments.

Though the problem of conceptual idolatry has captivated contemporary scholarship on the relationship between philosophy and theology, these discussions’ doctrinal consequences remain underdeveloped. I intervene in these debates by engaging and elucidating Martin Luther’s critique of scholastic metaphysics, a critique which foregrounds ontotheology’s spiritual and ecclesial detriments. Luther’s reforming works, from his pivotal 1525 De servo arbitrio to his last major project, the 1545 Genesis commentaries, reveal how a metaphysical theology based on natural reason leads to Pelagianism by generalizing faith (...) to a rational conceptual norm, the moral Law. Returning, however, to Scripture’s “grammar” – which, when read plainly, deconstructs natural reason’s vanity – allows us to encounter Christ ‘in person’ rather than in the concept. Luther thus suggests sola scriptura as a method for resisting ontotheology, but with dramatic dogmatic consequences, such as justification by faith alone. These consequences complicate modernity’s, and especially modern philosophy’s, theological origins and implications. (shrink)

Pickering & Garrod (P&G) propose that inner speech monitoring is subserved by predictions stemming from fast forward modeling. In this commentary, we question this alignment of language prediction with the inner speech monitor. We wonder how the speech monitor can function so efficiently if it is based on incomplete representations.

The relationship between the universal and the particular church was the subject of a comprehensive public debate between two German bishop theologians, namely Joseph Ratzinger and Walter Kasper. The debate was initially occasioned by an official document issued by the Congregation for the Doctrine of the Faith on the church as communion . The debate has clearly exposed ecclesiology’s complexities and tensions. Ratzinger taps biblical and theological sources in order to valorise unity or universality in an era of farreaching pluralisation. (...) His argumentation culminates in an endeavour to counter unilateral and horizontal ecclesiologies with an axiomatic ‘ontological and temporal primacy of the universal church over the particular churches’. Kasper recognizes genuine dangers in the one-sided ‘horizontalisation’ and fragmentation of ecclesiology. Rooted in his pastoral and oecumenical experience, he is of the opinion that the theological space created by Vatican II for the particular churches and the diocesan bishops should be claimed to the full. He detects a centralistic deformation of Vatican II in Ratzinger’s axiom. For Ratzinger Kasper’s standpoint can be the first step in an empirical reduction of ecclesiology. In this contribution, I have tried to demonstrate that Kasper’s ecclesiological perspective cannot be suspected of ‘de-theologisation’. Indeed, ‘re-theologisation’ can be understood as the central theme of his theology. The problem of determining the relationship between the universal church and the particular churches is given concrete form in the problem of determining the relationship between the office of bishop, the college of bishops in union with the pope, and the Petrine office. Kasper’s insistence on a legitimate degree of latitude for diocesan bishops does not imply that his goal is to decentralise the Petrine office both theologically and pastorally. At a certain moment in the debate, both theologians recognized that their differing perspectives were more a matter of theological opinion than of essential doctrinal conflict. Their mutual support of the idea of the ‘priority of internal unity’ is a crucial and unmistakable key concept for the correct understanding of the debate. (shrink)

The paper focuses on the thinking of Jonáš Záborský (1812–1876) and Štěpán Launer (1821–1851), which were marginalized in Slovak national-forming thinking. Emphasis is placed on the comparison between non-romantic nationalism and Štúr’s ethnic enthusiasm. Attention is paid to the value of their thinking, which can be analyzed in the context of reflections in the role of cultural identity in Štúr’s conception of culture and its place in relation to European cultural and civilizational affiliation. At the same time, the critique of (...) romantic thinking draws attention to the issue of the responsibility of nation-forming elites for the concept of civic development, which holistically approaches social change. Launer’s and, partly Záborský’s thinking draws attention to the dangers associated with the romantic search for ethnocultural specifics, which may result in the questioning the importance of civil liberties and Western cultural and civilizational affiliation.

One of the oldest platitudes about beauty is that it is pleasant to perceive or experience. In this article, I take this platitude at face value and try to explain why experiences of beauty are seemingly always accompanied by pleasure. Unlike explanations that have been offered in the past, the explanation proposed is designed to suit a “realist” view on which beauty is an irreducibly evaluative property, that is, a value. In a nutshell, the explanation is that experiences of beauty (...) are experiences in which it appears that something is beautiful, and that such experiences are identical to experiences of aesthetic pleasure.

This article examines the relationship between women entrepreneurs’ job autonomy and work–life balance, with a particular focus on how this relationship might be augmented by environments that discriminate against women, whether socio-economically, institutionally, or culturally. Multisource data pertaining to 5334 women entrepreneurs from 37 countries indicate that their sense of job autonomy increases the likelihood that they feel satisfied with their ability to balance the needs of their work with those of their personal life. This process is particularly prominent when (...) they operate in countries characterized by discriminatory socio-economic and institutional conditions, though a mitigating instead of invigorating effect arises in culturally discriminatory settings. For business ethics scholars and practitioners, these findings indicate how the extent to which women entrepreneurs, seeking to combine professional and private responsibilities, derive benefits from initiatives aimed at enhancing their job-related freedom critically depends on whether they operate in adverse external environments.

Criteria of identity should mirror the identity relation in being reflexive, symmetrical, and transitive. However, this logical requirement is only rarely met by the criteria that we are most inclined to propose as candidates. The present paper addresses the question how such obvious candidates are best approximated by means of relations that have all of the aforementioned features, i.e., which are equivalence relations. This question divides into two more basic questions. First, what is to be considered a ‘best’ approximation. And (...) second, how can these best approximations be found? In answering these questions, we both rely on and constructively criticize ground-breaking work done by Timothy Williamson. Guiding ideas of our approach are that we allow approximations by means of overlapping equivalence-relations, and that closeness of approximation is measured in terms of the number of mistakes made by the approximation when compared to the obvious candidate criterion.

A series of unnoticeably small changes in an observable property may add up to a noticeable change. Crispin Wright has used this fact to prove that perceptual indiscriminability is a non-transitive relation. Delia Graff has recently argued that there is a 'tension' between Wright's assumptions. But Graff has misunderstood one of these, that 'phenomenal continua' are possible; and the other, that our powers of discrimination are finite, is sound. If the first assumption is properly understood, it is not in tension (...) with but is actually implied by the second, given a plausible physical assumption. (shrink)

This study adds to business ethics research by examining how employees’ religiosity might enhance their propensity to engage in change-oriented citizenship behavior, as well as how this effect may be invigorated in adverse organizational climates with respect to voluntarism. Two-wave survey data collected from employees in Pakistan show that change-oriented citizenship activities increase to the extent that employees can draw on their personal resource of religiosity and perceive little adversity, measured in this study with respect to whether voluntarism is encouraged. (...) Further, the relative usefulness of religiosity for spurring change-oriented citizenship behavior is particularly strong when employees experience high levels of this organizational adversity, because employees with high religiosity tend to believe that such behavior is more needed in these organizational contexts. For organizations, these results demonstrate that the energy derived from religiosity may stimulate voluntary efforts that invoke organizational change, and the perceived value of such energy allocation is greater when employees perceive organizational environments that provide little encouragement to go beyond formal job duties.

If possible worlds are conjunctions of states of affairs, as in David Armstrong’s combinatorial theory, then is the empty world to be thought of as the null conjunction of states of affairs? The proposal seems plausible, and has received support from David Efird, Tom Stoneham, and Armstrong himself. However, in this paper, it is argued that the proposal faces a trilemma: either it leads to the absurd conclusion that the actual world is empty; or it reduces to a familiar representation (...) of the empty world in which the concept of a null conjunction plays no role; or it needs to make room for the null individual of certain non-classical mereologies.

Art restorations often give rise to controversy, and the reason does not always seem to be a lack of skill or dedication on the side of the restorer. Rather, in some of the most famous cases, the reason seems to be a lack of agreement on basic principles. In particular, there seems to be a lack of agreement on how the following two questions are to be answered. First, what is art restoration supposed to achieve, in other words, what is (...) the goal of restoration? Second, how can this goal be achieved, in other words, what are the means that a restorer can legitimately make use of? In this paper, I formulate, and defend, a principle that answers these questions. Although the principle may sound platitudinous, it has been contradicted by prominent philosophers and by important organizations concerned with conservation. Moreover, defending the principle turns out to be impossible without touching on such vexed philosophical issues as the ontology and identity of artworks, as well as the nature of perceptual and aesthetic properties (including the nature of artistic value).
