When making end-of-life decisions in intensive care units (ICUs), different staff groups have different roles in the decision-making process and may not always assess the situation in the same way. The aim of this study was to examine the challenges Danish nurses, intensivists, and primary physicians experience with end-of-life decisions in ICUs and how these challenges affect the decision-making process. Interviews with nurses, intensivists, and primary physicians were conducted, and data is discussed from an ethical perspective. All three groups found (...) that the main challenges were associated with interdisciplinary collaboration and future perspectives for the patient. Most of these challenges were connected with ethical issues. The challenges included different assessments of treatment potential, changes and postponements of withholding and withdrawing therapy orders, how and when to identify patients’ wishes, and suffering caused by the treatment. To improve end-of-life decision-making in the ICU, these challenges need to be addressed by interdisciplinary teams. (shrink)

The commentaries on the Ethica nova and the Ethica vetus written by some masters of the arts – presumably operating in the Paris faculty – in the first half of the thirteenth century expound in an original way the doctrine of the virtutes consuetudinales which Aristotle, at the end of the first book of his Ethica (I 13), distinguishes into the two main classes of the “moral virtues” and the “intellectual virtues”. The present paper aims at highlighting the particularly important (...) task which is assigned to the intellectual virtues in these early commentaries: joining man to God directly, through a contemplation which becomes love. The masters of the arts maintain that the moral virtues, in spite of the definition given by Aristotle (habitus a quo quis bonus est et opus eius bene reddit), are not sufficient alone to bring man to perfection, but that other more perfect virtues, namely the intellectual ones, are needed in order to make him know and love the supreme good. Having no knowledge of the sixth book of the Ethica, in which Aristotle deals in particular with the intellectual virtues, our masters know only their general description and are concerned with clarifying their relationships with the moral virtues, compared to which they appear to be sometimes really distinct and sometimes united to them in sharing the recta ratio, so much that they may constitute a double virtue. Although the masters of the arts seem to be well-informed about the teaching of the theologians – which they often cite without opposing to it, albeit stressing their own philosophical point of view –, it is significant that no reference whatsoever is made by them to the theological virtues and that they have recourse to the themes of Avicennian mysticism such as the doctrine of the two faces of the soul. Besides presenting the commentaries on the Ethica vetus from a general point of view, I will focus on the Paris commentary in Ethicam veterem (Paris BN lat. 3804A, ff. 152ra-159vb, 241ra-247vb; Paris BN lat. 3572, ff. 226ra-235ra), of which I am preparing a critical edition. The Paris commentary contains in fact a special and original discussion of the doctrine of the virtutes intellectuales. (shrink)

Recently, several scholars have argued that scientists can accept scientific claims in a collective process, and that the capacity of scientific groups to form joint acceptances is linked to a functional division of labor between the group members. However, these accounts reveal little about how the cognitive content of the jointly accepted claim is formed, and how group members depend on each other in this process. In this paper, I shall therefore argue that we need to link analyses of joint (...) acceptance with analyses of distributed cognition. To sketch how this can be done, I shall present a detailed case study, and on the basis of the case, analyze the process through which a group of scientists jointly accept a new scientific claim and at a later stage jointly accept to revise previously accepted claims. I shall argue that joint acceptance in science can be established in situations where an overall conceptual structure is jointly accepted by a group of scientists while detailed parts of it are distributed among group members with different areas of expertise, a condition that I shall call a heterogeneous conceptual consensus. Finally, I shall show how a heterogeneous conceptual consensus can work as a constraint against scientific change and address the question how changes may nevertheless occur. (shrink)

This article argues for the value of working with conflicts in social practice as resources for collaboration, learning and development. The interest in conflicts in social practice is rooted in a preoccupation with social power relations and how to understand and analyse power relations from a subject-science perspective. Following this interest, a methodological framework, best described as a kind of ‘mobile ethnography’, is discussed and exemplified through an empirical example. A preliminary conceptual framework for understanding power as a capacity for (...) action is presented. The overarching ambition of the article is to consider what democratic collaboration and coexistence entails and how it might be supported conceptually and analytically by the notion of conflicts as heuristics for social inquiry and by the notion of power as a capacity for action and social participation.

One of the fundamental problems of epistemology is to say when the evidence in an agent’s possession justifies the beliefs she holds. In this paper and its prequel, we defend the Bayesian solution to this problem by appealing to the following fundamental norm: Accuracy An epistemic agent ought to minimize the inaccuracy of her partial beliefs. In the prequel, we made this norm mathematically precise; in this paper, we derive its consequences. We show that the two core tenets of Bayesianism (...) follow from the norm, while the characteristic claim of the Objectivist Bayesian follows from the norm along with an extra assumption. Finally, we consider Richard Jeffrey’s proposed generalization of conditionalization. We show not only that his rule cannot be derived from the norm, unless the requirement of Rigidity is imposed from the start, but further that the norm reveals it to be illegitimate. We end by deriving an alternative updating rule for those cases in which Jeffrey’s is usually supposed to apply. (shrink)

Business scholars have recently proposed that the virtue of personal wisdom may predict leadership behaviors and the quality of leader–follower relationships. This study investigated relationships among leaders’ personal wisdom—defined as the integration of advanced cognitive, reflective, and affective personality characteristics (Ardelt, Hum Dev 47:257–285, 2004)—transformational leadership behaviors, and leader–member exchange (LMX) quality. It was hypothesized that leaders’ personal wisdom positively predicts LMX quality and that intellectual stimulation and individualized consideration, two dimensions of transformational leadership, mediate this relationship. Data came from (...) 75 religious leaders and 1–3 employees of each leader (N = 158). Results showed that leaders’ personal wisdom had a positive indirect effect on follower ratings of LMX quality through individualized consideration, even after controlling for Big Five personality traits, emotional intelligence, and narcissism. In contrast, intellectual stimulation and the other two dimensions of transformational leadership (idealized influence and inspirational motivation) did not mediate the positive relationship between leaders’ personal wisdom and LMX quality. Implications for future research on personal wisdom and leadership are discussed, and some tentative suggestions for leadership development are outlined. (shrink)

Ernst Cassirer Ernst Cassirer was the most prominent, and the last, Neo-Kantian philosopher of the twentieth century. His major philosophical contribution was the transformation of his teacher Hermann Cohen ’s mathematical-logical adaptation of Kant’s transcendental idealism into a comprehensive philosophy of symbolic forms intended to address all aspects of human cultural life and creativity.

In everyday life we either express our beliefs in all-or-nothing terms or we resort to numerical probabilities: I believe it's going to rain or my chance of winning is one in a million. The Stability of Belief develops a theory of rational belief that allows us to reason with all-or-nothing belief and numerical belief simultaneously.

This essay develops a joint theory of rational (all-or-nothing) belief and degrees of belief. The theory is based on three assumptions: the logical closure of rational belief; the axioms of probability for rational degrees of belief; and the so-called Lockean thesis, in which the concepts of rational belief and rational degree of belief figure simultaneously. In spite of what is commonly believed, this essay will show that this combination of principles is satisfiable (and indeed nontrivially so) and that the principles (...) are jointly satisfied if and only if rational belief is equivalent to the assignment of a stably high rational degree of belief. Although the logical closure of belief and the Lockean thesis are attractive postulates in themselves, initially this may seem like a formal “curiosity”; however, as will be argued in the rest of the essay, a very reasonable theory of rational belief can be built around these principles that is not ad hoc and that has various philosophical features that are plausible independently. In particular, this essay shows that the theory allows for a solution to the Lottery Paradox, and it has nice applications to formal epistemology. The price that is to be paid for this theory is a strong dependency of belief on the context, where a context involves both the agent's degree of belief function and the partitioning or individuation of the underlying possibilities. But as this essay argues, that price seems to be affordable. (shrink)

The influence of conscience on nurses in terms of guilt has frequently been described but its impact on care has received less attention. The aim of this study was to describe nurses' conceptions of the influence of conscience on the provision of inpatient care. The study employed a phenomenographic approach and analysis method. Fifteen nurses from three hospitals in western Sweden were interviewed. The results showed that these nurses considered conscience to be an important factor in the exercise of their (...) profession, as revealed by the descriptive categories: conscience as a driving force; conscience as a restricting factor; and conscience as a source of sensitivity. They perceived that conscience played a role in nursing actions involving patients and next of kin, and was an asset that guided them in their efforts to provide high quality care. (shrink)

Increasing interest in applying the theory and practice of deliberative democracy to new and varied political contexts leads us to ask whether or not deliberation is a universal political practice. While deliberation does manifest a universal competence, its character varies substantially across time and space, a variation partially explicable in cultural terms. We deploy an intersubjective conception of culture in order to explore these differences. Culture meets deliberation where publicly accessible meanings, symbols, and norms shape the way political actors engage (...) one another in discourse. Fuller understanding of political deliberation requires comparative and historical studies of particular contexts. We look at one case from Egypt in some depth and provide shorter illustrations from Botswana, Europe, India, Japan, Madagascar, the United States, Yemen, and elsewhere. Cross-cultural learning can enrich the theory of deliberative democracy, and give democratic theory a more universal reach. (shrink)

Thomas Kuhn's Structure of Scientific Revolutions became the most widely read book about science in the twentieth century. His terms 'paradigm' and 'scientific revolution' entered everyday speech, but they remain controversial. In the second half of the twentieth century, the new field of cognitive science combined empirical psychology, computer science, and neuroscience. In this book, the theories of concepts developed by cognitive scientists are used to evaluate and extend Kuhn's most influential ideas. Based on case studies of the Copernican revolution, (...) the discovery of nuclear fission, and an elaboration of Kuhn's famous 'ducks and geese' example of concept learning, this volume, first published in 2006, offers accounts of the nature of normal and revolutionary science, the function of anomalies, and the nature of incommensurability.

Transfers of critically ill neonates are frequent phenomena. Even though parents’ participation is regarded as crucial in neonatal care, a transfer often means that parents and neonates are separated. A systematic review of the parents’ experiences of neonatal transfer is lacking. This paper describes a meta‐study addressing qualitative research about parents’ experiences of neonatal transfer. Through deconstruction and reflections of theories, methods, and empirical data, the aim was to achieve a deeper understanding of theoretical, empirical, contextual, historical, and methodological issues (...) of qualitative studies concerning parents’ experiences of neonatal transfer over the course of this meta‐study (2000–2017). Meta‐theory and meta‐method analyses showed that caring, transition, and family‐centered care were main theoretical frames applied and that interviewing with a small number of participants was the preferred data collection method. The meta‐data‐analysis showed that transfer was a scary, unfamiliar, and threatening experience for the parents; they were losing familiar context, were separated from their neonate, and could feel their parenthood disrupted. We identified ‘wavering and wandering’ as a metaphoric representation of the parents’ experiences. The findings add knowledge about meta‐study as an approach for comprehensive qualitative research and point at the value of meta‐theory and meta‐method analyses. (shrink)

Based on fieldwork in northern Senegal, this paper shows how some pastoralists in Ferlo have managed to use market opportunities as a means to maintain their “pastoral way of life” Increased market involvement has enlarged the field of opportunities for pastoral activities as well as the vulnerability of these activities. This has given rise to a dialectic process of diversification and specialization. The paper is concerned with the portfolio of livelihood activities pastoralists use in order to respond to adverse socio-economic (...) and environmental conditions. Depending on the possibilities and values of a household, a certain combination of activities is chosen and this may change from one year to another. Hence, the activities are used in a dynamic way within households. On the basis of pastoral livelihood activities, four ideal types of pastoral livelihood strategies can be constructed: “agro-pastoralism,” “Tabaski pastoralism,” “commercial pastoralism,” and “non-herding pastoralism.” These four types illustrate how pastoralists re-invent their livelihoods in order to continue a pastoral way of life.

One of the fundamental problems of epistemology is to say when the evidence in an agent’s possession justifies the beliefs she holds. In this paper and its sequel, we defend the Bayesian solution to this problem by appealing to the following fundamental norm: Accuracy An epistemic agent ought to minimize the inaccuracy of her partial beliefs. In this paper, we make this norm mathematically precise in various ways. We describe three epistemic dilemmas that an agent might face if she attempts (...) to follow Accuracy, and we show that the only inaccuracy measures that do not give rise to such dilemmas are the quadratic inaccuracy measures. In the sequel, we derive the main tenets of Bayesianism from the relevant mathematical versions of Accuracy to which this characterization of the legitimate inaccuracy measures gives rise, but we also show that Jeffrey conditionalization has to be replaced by a different method of update in order for Accuracy to be satisfied.

In this book, Hannes Charen presents an alternative examination of kinship structures in political theory. Employing a radically transdisciplinary approach, On the Politics of Kinship is structured in a series of six theoretical vignettes or frames. Each chapter frames a figure, aspect, or relational context of the family or kinship. Some chapters are focused on a critique of the family as a state-sanctioned institution, while others cautiously attempt to recast kinship in a way to reimagine mutual obligation through the generation (...) of kinship practices understood as a perpetually evolving set of relational responses to finitude. In doing so, Charen considers the ways in which kinship is a plastic social response to embodied exposure, both concealed and made more evident in the bloated, feeble, and broken individualities and nationalities that seem to dominate our social and political landscape today. On the Politics of Kinship will be of interest to political theorists, feminists, anthropologists, and social scientists in general. (shrink)

This essay is a critical review of two recent collections, Feminism and Foucault: Reflections on Resistance, edited by Irene Diamond and Lee Quinby and Feminism as Critique: On the Politics of Gender, edited by Seyla Benhabib and Drucilla Cornell. While the collections differ in their manner of addressing the critical sources that have inspired them-the former relying upon a single theorist, the latter attempting to move through some of the philosophical history that constitutes our present theoretical terrain-both attempt to (...) think through and thus revisualize some of the categories of difference which we have inherited. Though the best essays from these collections are celebrated for demonstrating how "feminism as critique" can work to move us toward a clearer and more inclusive feminist theory, questions are raised about what the inattention to race in these volumes suggests about our own role in the construction of power and knowledge, and the erasures that help to secure them both.

In Glas Derrida asserts that Hegel’s Phenomenology of Spirit, in its reading of Antigone, favors consciousness (over the unconscious) by first acknowledging the achievement of ethical plenitude by Antigone, as she comes to full recognition of two contradictory laws, that of the divine and that of the communal spheres, and consequently repressing this speculative accomplishment by her fateful disappearance from both texts. This article complicates the argument by looking at the role that literature takes not only in philosophy, but in (...) the expression of speculative dialectics as such. What for Hegel can be included in a system? How does the impossible figure (Antigone), its expression and then exclusion enter and abandon the system? This text looks at war, burial and incest expressed by the role of Antigone in the Phenomenology of Spirit. (HC) © 2011 by The Board of Regents of the University of Wisconsin System . (shrink)

In “On what matters: Personal identity as a phenomenological problem” (2020), Steven Crowell engages a number of contemporary interpretations of Husserl’s account of the person and personal identity by noting that they lack a phenomenological elucidation of the self as commitment. In this article, in response to Crowell, I aim to show that such an account of the self as commitment can be drawn from Husserl’s work by looking more closely at his descriptions from the time of Ideas and after (...) of the self as ego or I and egoic experience as attentive experience. I specifically aim to sketch the beginning of a response to three questions I take Crowell to be posing to a Husserlian account of the person and personal identity: (1) What more than pre-reflective self-awareness can be attributed to the self on phenomenological grounds so that we can understand, phenomenologically speaking, how selves become persons? (2) How can what characterizes the self in addition to pre-reflective self-awareness be discerned in both our commitment to truth and our feeling bound by love and other emotive commitments that cannot be fully rationally justified, which Husserl acknowledges are both sources of personal self-constitution? And (3), do all selves become persons? In the paper I elaborate how my answers to the first two questions turn on the self not just being self-aware but active in a particular sense. And to begin to address the third question, I suggest that while any form of wakeful conscious experience is both self-aware and active, this activity of the self makes a difference for those who are socio-historically embedded in the way we are. Specifically, on the proposed Husserlian account, selves that are socio-historically embedded become persons in and through their active relating to what they attentively experience. In concluding, I indicate how this Husserlian account might compare to Crowell’s claim that “self-identity (ipseity) is not mere logical identity (A=A) but a normative achievement […] which makes a ‘personal’ kind of identity possible” (2020).

This article introduces, studies, and applies a new system of logic which is called ‘HYPE’. In HYPE, formulas are evaluated at states that may exhibit truth value gaps and truth value gluts. Simple and natural semantic rules for negation and the conditional operator are formulated based on an incompatibility relation and a partial fusion operation on states. The semantics is worked out in formal and philosophical detail, and a sound and complete axiomatization is provided both for the propositional and the (...) predicate logic of the system. The propositional logic of HYPE is shown to contain first-degree entailment, to have the Finite Model Property, to be decidable, to have the Disjunction Property, and to extend intuitionistic propositional logic conservatively when intuitionistic negation is defined appropriately by HYPE’s logical connectives. Furthermore, HYPE’s first-order logic is a conservative extension of intuitionistic logic with the Constant Domain Axiom, when intuitionistic negation is again defined appropriately. The system allows for simple model constructions and intuitive Euler-Venn-like diagrams, and its logical structure matches structures well-known from ordinary mathematics, such as from optimization theory, combinatorics, and graph theory. HYPE may also be used as a general logical framework in which different systems of logic can be studied, compared, and combined. In particular, HYPE is found to relate in interesting ways to classical logic and various systems of relevance and paraconsistent logic, many-valued logic, and truthmaker semantics. On the philosophical side, if used as a logic for theories of type-free truth, HYPE is shown to address semantic paradoxes such as the Liar Paradox by extending non-classical fixed-point interpretations of truth by a conditional as well-behaved as that of intuitionistic logic. Finally, HYPE may be used as a background system for modal operators that create hyperintensional contexts, though the details of this application need to be left to follow-up work. (shrink)

Thomas Nagel recognizes that it is commonly believed that people can neither be held morally responsible nor morally assessed for what is beyond their control. Yet he is convinced that although such a belief may be intuitively plausible, upon reflection we find that we do make moral assessments of persons in a large number of cases in which such assessments depend on factors not under their control. Of such factors he says: (p. 26).

Ethical decision making is of concern to researchers across all fields. However, researchers typically focus on the biases that may act to undermine ethical decision making. Taking a new approach, this study focused on identifying the most common compensatory strategies that counteract those biases. These strategies were identified using a series of interviews with university researchers in a variety of areas, including biological, physical, social, and health as well as scholarship and the performing arts. Interview transcripts were assessed with two (...) scoring procedures, an expert rating system and computer-assisted qualitative analysis. Although the expert rating system identified Understanding Guidelines, Recognition of Insufficient Information, and Recognizing Boundaries as the most frequently used compensatory strategies across fields, other strategies, Striving for Transparency, Value/norm Assessment, and Following Appropriate Role Models, were identified as most common by the computer-assisted qualitative analyses. Potential reasons for these findings and implications for training and practice are identified and discussed. (shrink)

We give an overview of the role of equicontinuity of sequences of real-valued functions on [0,1] and related notions in classical mathematics, intuitionistic mathematics, Bishop’s constructive mathematics, and Russian recursive mathematics. We then study the logical strength of theorems concerning these notions within the programme of Constructive Reverse Mathematics. It appears that many of these theorems, like a version of Ascoli’s Lemma, are equivalent to fan-theoretic principles.

‘‘Post-normal science’’ has received much attention in recent years, but like many iconic concepts, it has attracted differing conceptualizations, applications, and implications, ranging from being a ‘‘cure-all’’ for democratic deficit to the key to achieving more sustainable futures. This editorial article introduces a Special Issue that takes stock of research on PNS and critically explores how such research may develop. Through reviewing the history and evolution of PNS, the authors seek to clarify the extant definitions, conceptualizations, and uses of PNS. (...) The authors identify five broad areas of research on, or using, PNS which have developed over four decades. Their analysis suggests that the 1990s represent a symbolic watershed in the use of PNS terminology, when the concept was further developed and applied to highly complicated issues such as climate change. The authors particularly distinguish between uses of PNS as a normative prescription and as a practical method. Through this classification, they set out gaps and research questions arising. They then briefly summarize the Special Issue articles and consider their relationship to each other and the research questions raised by their analysis. They conclude by considering what the articles in this issue suggest for future theory building in PNS and related scholarship. (shrink)

When do children acquire a propositional attitude folk psychology or theory of mind? The orthodox answer to this central question of developmental ToM research had long been that around age 4 children begin to apply “belief” and other propositional attitude concepts. This orthodoxy has recently come under serious attack, though, from two sides: Scoffers complain that it over-estimates children’s early competence and claim that a proper understanding of propositional attitudes emerges only much later. Boosters criticize the orthodoxy for underestimating early (...) competence and claim that even infants ascribe beliefs. In this paper, the orthodoxy is defended on empirical grounds against these two kinds of attacks. On the basis of new evidence, not only can the two attacks safely be countered, but the orthodox claim can actually be strengthened, corroborated and refined: what emerges around age 4 is an explicit, unified, flexibly conceptual capacity to ascribe propositional attitudes. This unified conceptual capacity contrasts with the less sophisticated, less unified implicit forms of tracking simpler mental states present in ontogeny long before. This refined version of the orthodoxy can thus most plausibly be spelled out in some form of 2-systems-account of theory of mind. (shrink)

The increasing interconnectedness of academic research and external industry has left research vulnerable to conflicts of interest. These conflicts have the potential to undermine the integrity of scientific research as well as to threaten public trust in scientific findings. The present effort sought to identify themes in the perspectives of faculty researchers regarding conflicts of interest. Think-aloud interview responses were qualitatively analyzed in an effort to provide insights with regard to appropriate ways to address the threat of conflicts of interest (...) in research. Themes in participant responses included disclosure of conflicts of interest, self-removal from situations where conflict exists, accommodation of conflict, denial of the existence of conflict, and recognition of complexity of situations involving conflicts of interest. Moral disengagement operations are suggested to explain the appearance of each identified theme. In addition, suggestions for best practices regarding addressing conflicts of interest given these themes in faculty perspectives are provided. (shrink)
