A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein's famous E = mc² . The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

One of Weatherson's main goals is to drive home a methodological point: We shouldn't be looking for deductive arguments for or against relativism – we should instead be evaluating inductive arguments designed to show that either relativism or some alternative offers the best explanation of some data. Our focus in Chapter Two on diagnostics for shared content allegedly encourages the search for deductive arguments and so does more harm than good. We have no methodological slogan of our own to offer. (...) Part of what we were trying to do was to clearly articulate what the relevant issues even are. Often relativism is characterized in a way that is offhand and sloppy. The relativist, we are told, accepts 'disquotational truth' for various kinds of claims but denies that they are 'true simpliciter'. What exactly is going on here? Do the relevant distinctions even make sense? Before engaging in various abductive manoevers we need to get much clearer about what it is that we are trying to argue for and against. That said we are perfectly happy with the kind of inductive enterprise that Weatherson sketches. For our part, we were fully aware (and indeed explicit) that the 'agreement' diagnostic does not ‘deductively’ settle all of the relevant disputes. A significant part of Chapter Four is dedicated to something in the vicinity of Weatherson's project. Note, indeed, that our diagnostics are even stated using the ideology of 'providing evidence' – hardly the basis for a straightforwardly deductive argument for or against relativism. Finally, though, we should point out that we are not hostile to deductive arguments against relativism. A philosopher's evidence is theory-laden and in part owes itself to epistemic powers that his or her opponents may not acknowledge. In short, their evidence may not always have the hallmarks of 'evidence neutrality' --- evidence that their opponents would recognize as such. We are perfectly open to there being compelling deductive arguments against relativism from such evidence.. (shrink)

In the ecumenical discussion, the lingering differences between the concessions are realised more generally again. Not only does this apply for dogmatics, but also for ethics. Eberhard Schockenhoff’s critical inquiries are recognised as a helpful impulse for the self-control of protestant ethics in the sense of an »ecumenism of objection«. However, Schockenhoff’s allegation of breaking with traditions in this respect calls for closer examination. Besides that, unsolved questions have to be put to Catholic moral theology. Some of these include the (...) role of the Christian teaching authority, and the exposure to plurality. (shrink)

All the medical and bioethical questions, ranging from stem cell research to converging technologies and synthetic biology, touch on the question regarding the image of human beings and their position in the cosmos, by which we are able to orient ourselves. This article argues that the biblical belief in creation and the discourse about humans as created beings by and in the image of God can still be proclaimed as a viable form of human self-interpretation in the present. The distinction (...) between practical knowledge and knowledge of orientation may be of help here. Guidance for how to live and act is not best found in abstract principles, but rather in meaningful stories, in metaphors and symbols. On this level, too, is also where faith in creation and the certainty of our own creatureliness is located. Contribution: This article interprets the doctrine of creation by a hermeneutical theology. It analyses the interdependence between hermeneutics and criticism in the process of reinterpreting the classical propositions about the human being and the world as God’s creation and the relation of anthropology and ethics. The aim is to show what might be the contribution of Christian faith in creation to the approach of an ethics of responsibility in the field of bioethics and ecology. The specific contribution of this article to current debates on an ethics of creation is the thesis that the key to a well-balanced theological approach to all this is the Pauline doctrine of justification as interpreted by the protestant reformers.

The concept of joint action is at the core of numerous diverse research topics, including philosophical explorations of social action, studies of human dialogue, human-computer interaction, computer-supported collaborative work, multiagent systems, distributed artificial intelligence, distributed simulation, and contract law. It is therefore remarkable that so central a concept has received so little detailed analysis, in comparison with studies of individuals. However, in recent years, the study of joint action has begun to undergo more intense scrutiny, primarily from philosophers and researchers (...) in artificial intelligence. These two disciplines often address similar topics but with different motivations, methodologies, tools, and criteria for success. Although this paper is inspired by philosophical work, it is squarely motivated by the concerns of building intelligent systems that are capable of collaborative behavior, either with a user, or with other such systems. Still, we hope that the paper sheds light on philosophical issues, and treats the subject of joint action at a sufficiently precise level to be illuminating of problems that any philosophical account needs to confront.

Das Phänomen des Ethischen ist dem Konflikt der Interpretationen ausgesetzt. Er äußert sich nicht nur in ethischen Kontroversen, sondern auch als Konflikt ethischer Grundkonzeptionen und Menschenbilder. Verstärkt wird in jüngster Zeit über das spezifische Profil evangelischer Ethik und Urteilsbildung nachgedacht. Die Beiträge dieses Buches konfrontieren entsprechende Bemühungen mit der provokanten These R. Bultmanns, es gebe gar keine christliche Ethik, sofern darunter einer Theorie über das verstanden werde, was Christen zu tun und zu lassen haben.

"This book contains ideas to develop interdisciplinary and transdisciplinary views on economy and society. It aims to disseminate heterodox ideas on various subjects related to economics and global society. The book is organised in six parts. Part 1 contains the key lectures of Backhaus on the concept of state sciences and of Klamer on the importance of culture for economics. Parts 2- 6 contain successively contributions in the areas of economic paradigms and theories, population and society, corporate issues, environment, and (...) international relations. Examples of the content are: - the changes of family life cycles due to the rise of non-traditional households; - subjective and objective inflation rates after the introduction of the Euro; - the economics of genetic engineering; - the contribution of foreign direct investment to the economic development of host countries; - the inaccuracy of economic models applied in places characterized by extreme income disparities; - the improvement of political and corporate governance; - evolutionary thinking and emission trading; - freedom and order in the European Union; - the reform of social policy in Europe. The book provides interesting creative multi-disciplinary ideas with respect to various topical issues concerning the contemporary global society. It is highly recommended for economists and social scientists in search of broad views on social science and society.". (shrink)

The nationwide supply with the afferings of Palliative Care is a generally acknowledged aim. But it is disputed whether it is a sufficient alternative to death on demand or assisted suicide. This is being discussed on a European level. But what the current discussion is Jacking of, are empirical studies regarding the culture of dying. The case study at hand Iooks into the basic social and cultural conditions in a large city. It also discusses the consequences of religious change and (...) the inter-religious situation on the palliativemovement and their relation to the churches. (shrink)

An increasingly number of patients in Western civilizations suffer from weak authenticity structure which is characterized by a lack of self-realization, autonomy, character strength, stereotype behavior, inability to use (internal) dialogue in order to learn about oneself and defining oneself as a individual, and so on. In this paper a theoretical model of fragile authenticity structure and some suggestions to regain a more authentic attitude are presented.
