Dans l'oeuvre d'Edith Stein, l'alterite apparait comme constitutive de la personne humaine. D'un point de vue proprement subjectif, l'alterite renvoie... l'alter ego,... la dimension communautaire et, dans une perspective croyante, au Tout-Autre. D'un point de vue objectif, elle designe les valeurs, qui faconnent la personnalite, et la foi, qui vient au secours de la raison humaine. Un parcours des oeuvres principales de l'auteur permet de prendre la mesure... la fois de la continuite et de l'evolution de sa pensee. A partir (...) de l..., l'etude entreprend de mettre en evidence, d'une part, l'originalite de la pensee d'Edith Stein par rapport... celle de Husserl et, d'autre part, comment Edith Stein se situe par rapport... la pensee de Thomas d'Aquin. L'influence de l'oeuvre de Jean de la Croix est egalement abordee. Enfin, en dialogue avec des auteurs comme Ricoeur, Levinas ou Ladriere, la troisieme partie du livre aborde de maniere critique la question de l'alterite comme fondement de la personne et cela selon trois parcours, l'un lie... la phenomenologie d'Edith Stein, l'autre... sa philosophie chretienne, et le dernier... son attrait pour la mystique.

Our lives are increasingly intertwined with the digital realm, and with new technology, new ethical problems emerge. The academic field that addresses these problems—which we tentatively call ‘digital ethics’—can be an important intellectual resource for policy making and regulation. This is why it is important to understand how the new ethical challenges of a digital society are being met by academic research. We have undertaken a scientometric analysis to arrive at a better understanding of the nature, scope and dynamics of (...) the field of digital ethics. Our approach in this paper shows how the field of digital ethics is distributed over various academic disciplines. By first having experts select a collection of keywords central to digital ethics, we have generated a dataset of articles discussing these issues. This approach allows us to generate a scientometric visualisation of the field of digital ethics, without being constrained by any preconceived definitions of academic disciplines. We have first of all found that the number of publications pertaining to digital ethics is exponentially increasing. We furthermore established that whereas one may expect digital ethics to be a species of ethics, we in fact found that the various questions pertaining to digital ethics are predominantly being discussed in computer science, law and biomedical science. It is in these fields, more than in the independent field of ethics, that ethical discourse is being developed around concrete and often technical issues. Moreover, it appears that some important ethical values are very prominent in one field (e.g., autonomy in medical science), while being almost absent in others. We conclude that to get a thorough understanding of, and grip on, all the hard ethical questions of a digital society, ethicists, policy makers and legal scholars will need to familiarize themselves with the concrete and practical work that is being done across a range of different scientific fields to deal with these questions.

A solution for cooperative games with transferable utility, or simply TU-games, assigns a payoff vector to every TU-game. In this paper we discuss two classes of equal surplus sharing solutions. The first class consists of all convex combinations of the equal division solution and the center-of-gravity of the imputation-set value. The second class is the dual class consisting of all convex combinations of the equal division solution and the egalitarian non-separable contribution value. We provide characterizations of the two classes of (...) solutions using either population solidarity or a reduced game consistency in addition to other standard properties. (shrink)

A situation, in which a finite set of players can obtain certain payoffs by cooperation can be described by a cooperative game with transferable utility, or simply a TU-game. A (point-valued) solution for TU-games assigns a payoff distribution to every TU-game. In this article we discuss a class of equal surplus sharing solutions consisting of all convex combinations of the CIS-value, the ENSC-value and the equal division solution. We provide several characterizations of this class of solutions on variable and fixed (...) player set. Specifications of several properties characterize specific solutions in this class. (shrink)

A symmetric network consists of a set of positions and a set of bilateral links between these positions. For every symmetric network we define a cooperative transferable utility game that measures the “power” of each coalition of positions in the network. Applying the Shapley value to this game yields a network power measure, the β-measure, which reflects the power of the individual positions in the network. Applying this power distribution method iteratively yields a limit distribution, which turns out to be (...) proportional to the well-known degree measure. We compare the β-measure and degree measure by providing characterizations, which differ only in the normalization that is used. (shrink)

We deal with the ranking problem of the nodes in a directed graph. The bilateral relationships specified by a directed graph may reflect the outcomes of a sport competition, the mutual reference structure between websites, or a group preference structure over alternatives. We introduce a class of scoring methods for directed graphs, indexed by a single nonnegative parameter α. This parameter reflects the internal slackening of a node within an underlying iterative process. The class of so-called internal slackening scoring methods, (...) denoted by λα, consists of the limits of these processes. It is seen that λ0 extends the invariant scoring method, while λ∞ extends the fair bets scoring method. Method λ1 corresponds with the existing λ-scoring method of Borm et al. (Ann Oper Res 109(1):61–75, 2002) and can be seen as a compromise between λ0 and λ∞. In particular, an explicit proportionality relation between λα and λ1 is derived. Moreover, the internal slackening scoring methods are applied to the setting of social choice situations where they give rise to a class of social choice correspondences that refine both the Top cycle correspondence and the Uncovered set correspondence.

We introduce a family of proportional surplus division values for TU-games. Each value first assigns to each player a compromise between her stand-alone worth and the average stand-alone worths over all players, and then allocates the remaining worth among the players in proportion to their stand-alone worths. This family contains the proportional division value and the new egalitarian proportional surplus division value as two special cases. We provide characterizations for this family of values, as well as for each single value (...) in this family. (shrink)

It is known that peer group games are a special class of games with a permission structure. However, peer group games are also a special class of digraph games. To be specific, they are digraph games in which the digraph is the transitive closure of a rooted tree. In this paper we first argue that some known results on solutions for peer group games hold more general for digraph games. Second, we generalize both digraph games as well as games with (...) a permission structure into a model called games with a local permission structure, where every player needs permission from its predecessors only to generate worth, but does not need its predecessors to give permission to its own successors. We introduce and axiomatize a Shapley value-type solution for these games, generalizing the conjunctive permission value for games with a permission structure and the β\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\beta $$\end{document}-measure for weighted digraphs.

The Shapley value is the unique value defined on the class of cooperative games in characteristic function form which satisfies certain intuitively reasonable axioms. Alternatively, the Banzhaf value is the unique value satisfying a different set of axioms. The main drawback of the latter value is that it does not satisfy the efficiency axiom, so that the sum of the values assigned to the players does not need to be equal to the worth of the grand coalition. By definition, the (...) normalized Banzhaf value satisfies the efficiency axiom, but not the usual axiom of additivity. (shrink)

A cooperative game with transferable utility–or simply a TU-game– describes a situation in which players can obtain certain payoffs by cooperation. A value function for these games assigns to every TU-game a distribution of payoffs over the players. Well-known solutions for TU-games are the Shapley and the Banzhaf value. An alternative type of solution is the concept of share function, which assigns to every player in a TU-game its share in the worth of the grand coalition. In this paper we (...) consider TU-games in which the players are organized into a coalition structure being a finite partition of the set of players. The Shapley value has been generalized by Owen to TU-games in coalition structure. We redefine this value function as a share function and show that this solution satisfies the multiplication property that the share of a player in some coalition is equal to the product of the Shapley share of the coalition in a game between the coalitions and the Shapley share of the player in a game between the players within the coalition. Analogously we introduce a Banzhaf coalition structure share function. Application of these share functions to simple majority games show some appealing properties. (shrink)

The humanistic disciplines aim to offer explanations of a wide variety of phenomena. Philosophical theories of explanation have focused mostly on explanations in the natural sciences; a much discussed theory of explanation is the causal theory of explanation. Recently it has come to be recognized that the sciences sometimes offer respectable explanations that are non-causal. This paper broadens the discussion by discussing explanations that are offered in the fields of history, linguistics, literary theory, and archaeology that do not seem to (...) fit the causal theory of explanation. We conducted an exploratory survey in acclaimed humanities textbooks to find explicitly so-called explanations and analyze their nature. The survey suggests that non-causal explanations are an integral part of the humanities and that they are of distinct kinds. This paper describes three kinds that are suggested by our survey: teleological, formal, and normative explanations. We suggest that such humanistic explanations strengthen the case for explanatory pluralism. (shrink)

This paper investigates conceptions of explanation, teleology, and analogy in the works of Immanuel Kant (1724-1804) and Georges Cuvier (1769-1832). Richards (2000, 2002) and Zammito (2006, 2012, 2018) have argued that Kant’s philosophy provided an obstacle for the project of establishing biology as a proper science around 1800. By contrast, Russell (1916), Outram (1986), and Huneman (2006, 2008) have argued, similar to suggestions from Lenoir (1989), that Kant’s philosophy influenced the influential naturalist Georges Cuvier. In this article, I wish to (...) expand on and further the work of Russell, Outram, and Huneman by adopting a novel perspective on Cuvier and considering (a) the similar conceptions of proper science and explanation of Kant and Cuvier, and (b) the similar conceptions of the role of teleology and analogy in the works of Kant and Cuvier. The similarities between Kant and Cuvier show, contrary to the interpretation of Richards and Zammito, that some of Kant’s philosophical ideas, whether they derived from him or not, were fruitfully applied by some life scientists who wished to transform life sciences into proper sciences around 1800. However, I also show that Cuvier, in contrast to Kant, had a workable strategy for transforming the life sciences into proper sciences, and that he departed from Kant’s philosophy of science in crucial respects.

This essay takes Arthur Danto’s end-of-art thesis as a case in point of a substantive philosophy of history. Such philosophy explains the direction that art has taken and why that direction could not have been different. Danto never scrutinized the philosophy of history that his end-of-art thesis presumes. I aim to do that by drawing a distinction between what I refer to as the common view of history and the philosophical view of history, and by arguing that we need the (...) latter if we want to properly assess the plausibility of the end-of-art thesis.

In this paper I explore, in sections 2 and 3, respectively, Herman Dooyeweerd’s notion of naive experience and the notion of common sense as found in the writings of Thomas Reid and G. E. Moore. I argue in section 4 that naive experience and common sense are assigned a structurally similar functional role by their advocates—viz., the role of touchstone for philosophy. In the final section I stage a conversation between Dooyeweerd and Reid about the touchstones they adopt.

In computer ethics, as in other branches of applied ethics, the problem of the justification of moral judgment is still unresolved. I argue that the method which is referred to as “The Method of Wide Reflective Equilibrium” (WRE) offers the best solution to it. It does not fall victim to the false dilemma of having to choose either case‐based particularist or principle‐based universalist approaches to the problem of moral justification. I claim that WRE also provides the best model of practical (...) moral reasoning available for computer ethics. It does not pretend to provide quasi‐algorithmic procedures for moral decision‐making, but neither does it abandon the regulative ideal of communicative transparency in discursive public justification.

In lieu of an abstract, here is a brief excerpt of the content:Thomas Reid on MemoryRené van Woudenbergthis paper is a discussion of Thomas Reid’s views on memory as an “avenue of knowledge.” Part 1 deals with various remarks Reid makes concerning memory, knowledge, and belief which he holds to be “obvious and certain.” Part contains a more detailed discussion of Reid’s thesis that “memory is unaccountable.” Part 3 inquires how Reid’s critique of the Way of Ideas fits with his (...) own views on memory.Reid’s dealings with memory are part of his broader inquiries into the intellectual faculties of the human mind. In the Essays on the Intellectual Powers of Man Reid discusses not only memory, but other avenues of knowledge as well, such as perception and reasoning. In these essays Reid is doing straight epistemology. This is not to deny that Reid addresses other topics as well. In the essay on memory, for instance, Reid criticizes John Locke’s account of personal identity. But even then his discussion focusses on epistemological matters; one of his conclusions, for example, is that Locke confounded personal identity with the evidence we have of our personal identity, a thesis, Reid points out, that is bristled with absurd consequences. Although, then, Reid’s views on memory are related with his views on personal identity, I will abstain from a discussion of the latter. His epistemology of memory, I think, warrants attention in its own right.11. memory, knowledge, and beliefI.IIn Essay III of his Essays on the Intellectual Powers of Man [1784],2 entitled “Of Memory,” Reid writes: [End Page 117]It is by memory that we have an immediate knowledge of things past. The senses give us information of things only as they exist in the present moment.(EIP 339)Memory, says Reid, gives us knowledge of things past, whereas sense perception gives us knowledge of things present. Reid takes it to be “obvious and certain” (as the title of the first chapter of Essay III indicates) that “The object of memory, or thing remembered, must be something that is past; as the object of perception... must be something which is present. What now is, cannot be an object of memory; neither can that which is past and gone be an object of perception” (EIP 340).These remarks may, however, occasion some doubts. One way of explaining Reid’s remark that the object of memory is something that is past, is that whenever someone, S, remembers something, viz., that p, p will be a proposition about something that is past.3 This explanation gives the right result for such propositions as there was snowfall in late August, and she once visited Finland4 But, as Norman Malcolm has observed, it does not always give the right results.5 For, he says, there are cases of S remembering that p, where p is not a proposition about the past. Let p be his telephone number is 2 79-289-59 75, or his car is in the garage. What is remembered, in these cases, is a proposition about something that is not past, but present (or: about what is presently the case). It is, so it seems at least, possible for S to remember the present.It even seems possible for S “to remember the future” (something Aristotle deemed impossible).6 S can remember, for instance, that the game starts at 8:00 P.M., or that there will be elections next year.No doubt some will find these suggestions preposterous. Still, we say such things as “I remember my telephone number” and “I remember the game starts at 8:00 P.M.” Someone who balks at the suggestion that we can remember present and even future things, therefore, has to find a way of dealing with these quite common modes of saying. One way would be to argue that these manners of saying are incorrect, another that they are elliptical. Since the first thesis is unconvincing (it is, after all, correct, i.e., correct English to use the expressions under consideration), we are left with the second, viz., that these modes of saying are elliptical. Can this be made acceptable? Let us see.Might... (shrink)

This chapter describes how philosophical theorizing about justice can be connected with empirical research in the social sciences. We begin by drawing on some received distinctions between ideal and non-ideal approaches to theorizing justice along several different dimensions, showing how non-ideal approaches are needed to address normative aspects of real-world problems and to provide practical guidance. We argue that there are advantages to a transitional approach to justice focusing on manifest injustices, including the fact that it enables us to set (...) aside some reasonable disagreements about justice. The ‘bottom-up’ approach we advocate, for which we borrow Wolff’s term ‘real-world political philosophy’, is an empirically-informed normative analysis that attends to specific, identifiable injustices, and thus is partial, though not isolationist. We illustrate our approach by considering how different models of the nature of disability suggest different kinds of remedy for injustices faced by persons living with disabilities. We reflect on the nature and significance of vulnerabilities, and we assess the role of public opinion in normative theorizing, suggesting a particular significance for the opinions and experiences of marginalized groups. We finally reflect on the relevance of European legal and institutional frameworks for theorizing justice in Europe. (shrink)

Introduction to collection of papers by group of scholars and ACO missionaries brought together to discuss the developments within the ACO over the past hundred years during a conference that was organised by Dr Wilbert van Saane of Haigazian University in January 2021.

The recent development of RNA replicating protocells and capsules that enclose complex biosynthetic cascade reactions are encouraging signs that we are gradually getting better at mastering the complexity of biological systems. The road to truly cellular compartments is still very long, but concrete progress is being made. Compartmentalization is a crucial natural methodology to enable control over biological processes occurring within the living cell. In fact, compartmentalization has been considered by some theories to be instrumental in the creation of life. (...) With the advancement of chemical biology, artificial compartments that can mimic the cell as a whole, or that can be regarded as cell organelles, have recently received much attention. The membrane between the inner and outer environment of the compartment has to meet specific requirements, such as semi‐permeability, to allow communication and molecular transport over the border. The membrane can either be built from natural constituents or from synthetic polymers, introducing robustness to the capsule. (shrink)

Desde un diálogo con Axel Honneth, argumentaremos primero que la metodología de crítica social desarrollada en la República posee elementos constructivo-racionales y reconstructivo-hermenéuticos. Luego, enfatizaremos dos conceptos prefigurados en dicha obra que, mediante Hegel, yacen en el trasfondo de la Teoría crítica, a saber: holismo y patología social. Ello nos permitirá articular, como conclusión, una “dialéctica de la justicia” que, en el sentido de Adorno & Horkheimer, recorre (...) la obra de Honneth. (shrink)

Background: Empirical studies in Muslim communities on organ donation and blood transfusion show that Muslim counsellors play an important role in the decision process. Despite the emerging importance of online English Sunni fatwas, these fatwas on organ donation and blood transfusion have hardly been studied, thus creating a gap in our knowledge of contemporary Islamic views on the subject.Method: We analysed 70 English Sunni e-fatwas and subjected them to an in-depth text analysis in order to reveal the key concepts in (...) the Islamic ethical framework regarding organ donation and blood transfusion.Results: All 70 fatwas allow for organ donation and blood transfusion. Autotransplantation is no problem at all if done for medical reasons. Allotransplantation, both from a living and a dead donor, appears to be possible though only in quite restricted ways. Xenotransplantation is less often mentioned but can be allowed in case of necessity. Transplantation in general is seen as an ongoing form of charity. Nearly half of the fatwas allowing blood transfusion do so without mentioning any restriction or problem whatsoever. The other half of the fatwas on transfusion contain the same conditional approval as found in the arguments pro organ transplantation.Conclusion: Our findings are very much in line with the international literature on the subject. We found two new elements: debates on the definition of the moment of death are hardly mentioned in the English Sunni fatwas and organ donation and blood transfusion are presented as an ongoing form of charity.

There is widespread understanding of the close connection between religion and the ecological crisis, and that in order to amend this crisis, theological resources are needed. This monograph seeks to contribute to this endeavor by engaging the theology of Dietrich Bonhoeffer. His theology is particularly suitable in this context, due to its open-ended nature, and to the prophetic and radical nature of the questions he was prepared to ask--that is why there are many other attempts to contextualize Bonhoeffer's theology in (...) areas that he himself has not directly written about. In this monograph, Steven van den Heuvel first of all addresses the question of how to translate Bonhoeffer's theology in a methodologically sound way. He settles on a modified form of the general method of correlation. Then, secondly, van den Heuvel sets out to describe five major concepts in Bonhoeffer's work, bringing these into critical interplay with discussions in environmental ethics and eco-theology. In making the correlations he thoroughly describes each concept, situating it in the historic and intellectual background of Bonhoeffer's time. He then transposes these concepts to contemporary environmental ethics, describing what contribution Bonhoeffer's theology can make. - back of book. (shrink)

The Radical Enactive/embodied view of Cognition, or REC, claims that all cognition is a matter of skilled performance. Yet REC also makes a distinction between basic and content-involving cognition, arguing that the development of basic to content-involving cognition involves a kink. It might seem that this distinction leads to problematic gaps in REC’s story. We address two such alleged gaps in this paper. First, we identify and reply to the concern that REC leads to an “interface problem”, according to which (...) REC has to account for the interaction of two minds co-present in the same cognitive activity. We emphasise how REC’s view of content-involving cognition in terms of activities that require particular sociocultural practices can resolve these interface concerns. The second potential problematic gap is that REC creates an unjustified difference in kind between animal and human cognition. In response, we clarify and further explicate REC’s notion of content, and argue that this notion allows REC to justifiably mark the distinction between basic and content-involving cognition as a difference in kind. We conclude by pointing out in what sense basic and content-involving cognitive activities are the same, yet different. They are the same because they are all forms of skilled performance, yet different as some forms of skilled performance are genuinely different from other forms. (shrink)
