Scientific policy advice is usually perceived as a formalized advisory process within political institutions. Politics has benefited from this arrangement because the science-based rationalization of policy has contributed to its legitimacy. However, in Western democratic societies, scientific expertise that is routinely mobilized to legitimate political positions has increasingly lost its power due to controversial expertise in the public sphere in particular within the mass media. As a consequence of the medialization of science, political decision makers are increasingly confronted with mass-mediated (...) expertise. Empirical results of a qualitative survey among decision makers in the German political and administrative system, presented in this article, support the hypothesis that mass-mediated expertise has a significant impact on policy processes. Five functions of media coverage on science-based issues for policy making were identified. Mass-mediated expertise has therefore altered the established relations between scientific policy advisors and political decision makers and can be seen as informal policy advice complementing institutionalized advisory arrangements.

We call a decision maker risk averse for losses if that decision maker is risk averse with respect to lotteries having alternatives below a given reference alternative in their support. A two-person bargaining solution is called invariant under risk aversion for losses if the assigned outcome does not change after correcting for risk aversion for losses with this outcome as pair of reference levels, provided that the disagreement point only changes proportionally. We present an axiomatic characterization of the Nash bargaining (...) solution based on this condition, and we also provide a decision-theoretic characterization of the concept of risk aversion for losses.

We consider choice correspondences that assign a subset to every choice set of alternatives, where the total set of alternatives is an arbitrary finite or infinite set. We focus on the relations between several extensions of the condition of independence of irrelevant alternatives on one hand, and conditions on the revealed preference relation on sets, notably the weak axiom of revealed preference, on the other hand. We also establish the connection between the condition of independence of irrelevant alternatives and so-called (...) strong sets; the latter characterize a social choice correspondence satisfying independence of irrelevant alternatives.

I should first of all like to greet His Excellency Msgr Josip Bozanic, Archbishop of Zagreb, His Excellency Msgr Giulio Einaudi, Apostolic Nuncio in Croatia, Their Lordships the Bishops, the authorities both civil and academic, the teaching and non-teaching staff, the students, my fellow Jesuits, and all the colleagues and friends present at this solemn opening of the new Chair in the Faculty of Philosophy and of Theological Study of the Society of Jesus at Zagreb. I thank heartily all those (...) who have in any way helped to bring this project to completion. I hope that it will enable us to render a valuable service to the Church in Croatia and to the culture of the Croatian people, a service that the Society of Jesus has held dear from its very beginning, striving to contribute, through its intellectual endeavours, to the understanding of the work of creation.

It is for me a source of great joy to meet with our collaborators in this magnificent Aula Magna of the Ignatianum to share on the intellectual ministry. You have a right to know how we Jesuits perceive the nature and mission of our educational institutions. Even university and cultural circles at large seek to know the spirit with which the Society of Jesus enters the world of science, research, academic instruction, and cultural activity generally. The reflection I am about (...) to submit is also meant to give impetus to the process the Polish Jesuits are involved in of defining their presence in the sector of education that after the fall of communism is experiencing a tremendous growth. All this is taking place in conjunction with the worldwide assessment the Society is making of its commitment to university education and the role it intends to play in it. (shrink)

Devotion and knowledge, pietas and eruditio, form a binomial idea which belongs to the tradition of the Society of Jesus. This idea was already important at the University of Paris when Ignatius and his companions studiedthere. Nevertheless, they gave an original interpretation to pietas in line with what Ignatius had already discovered in his own existence: devotion is not only a purely interior attitude but also a deeply apostolic one. From the binomial idea pietas-eruditio, and from its subsequent more precise (...) articulation, the study of theology in the Society draws out particular conclusions which are faithful to tradition and at the same time attentive to the new issues of a complex world requiring highly qualified and competent teaching. Theology in the Society is itself an apostolic enterprise. (shrink)

In this article three different types of loss aversion equilibria in bimatrix games are studied. Loss aversion equilibria are Nash equilibria of games where players are loss averse and where the reference points—points below which they consider payoffs to be losses—are endogenous to the equilibrium calculation. The first type is the fixed point loss aversion equilibrium, introduced in Shalev (2000; Int. J. Game Theory 29(2):269) under the name of ‘myopic loss aversion equilibrium.’ There, the players’ reference points depend on the (...) beliefs about their opponents’ strategies. The second type, the maximin loss aversion equilibrium, differs from the fixed point loss aversion equilibrium in that the reference points are only based on the carriers of the strategies, not on the exact probabilities. In the third type, the safety level loss aversion equilibrium, the reference points depend on the values of the own payoff matrices. Finally, a comparative statics analysis is carried out of all three equilibrium concepts in 2 × 2 bimatrix games. It is established when a player benefits from his opponent falsely believing that he is loss averse. (shrink)

We compare Colman's proposed “psychological game theory” with the existing literature on psychological games (Geanakoplos et al. 1989), in which beliefs and intentions assume a prominent role. We also discuss experimental evidence on intentions, with a particular emphasis on reciprocal behavior, as well as recent efforts to show that such behavior is consistent with social evolution.

Nash equilibria with identical supports are compared for bimatrix games that are different with respect to the risk aversion of player 2. For equilibria in 2× 2-bimatrix games and for equilibria with efficient supports in coordination games it is established for which cases increased risk aversion of player 2 benefits or hurts player 2.

Aspiration-based evolutionary dynamics have recently been used to model the evolution of fair play in the ultimatum game showing that incredible threats to reject low offers persist in equilibrium. We focus on two extensions of this analysis: we experimentally test whether assumptions about agent motivations (aspiration levels) and the structure of the game (binary strategy space) reflect actual play, and we examine the problematic assumption embedded in the standard replicator dynamic that unhappy agents who switch strategies may return to a (...) rejected strategy without exploring other options. We find that the resulting “no switchback” dynamic predicts the evolution of play better than the standard dynamic and that aspirations are a significant motivator for our participants. In the process, we also construct and analyze a variant of the ultimatum game in which players can adopt conditional (on their induced aspirations) strategies. (shrink)

Wenige Themen begleiten das menschliche Denken so bestandig wie die Frage nach dem Unendlichen. Die Arbeit geht ihr in Schellings fruhen Schriften nach, indem sie die unendliche Sphare als Raum des absoluten Ichs mithilfe geometrischer Konzeptionen konturiert, die Konstruktion der Naturprodukte in Schellings Naturphilosophie mittels mathematischer Reihen prazisiert und die komplizierten Verhaltnisse der Identitatsphilosophie durch die Mathematik des Unendlichen erhellt.Die Studie verdeutlicht aber auch, wie bedeutsam die Philosophie fur die Mathematik ist. Nach wie vor scheidet die in der Antike bekannte (...) und fruhneuzeitlich heftig debattierte Frage nach der Existenz einer aktualen Unendlichkeit die Geister. Die Studie untersucht das Unendliche als unabschliessbaren Prozess und geschlossene Gesamtheit. Der Anspruch von Systemtheorien, bundige Erklarungsmodelle vorzulegen, ist offensichtlich nur unter der Annahme einer aktualen Unendlichkeit einlosbar. (shrink)

Kaum ein anderer lebender Naturwissenschaftler besitzt die Fähigkeit, mit solcher Geistesklarheit die tiefsten Einsichten von moderner Quantenphysik mit dem uralten spirituellen Menschheitswissen zu verknüpfen wie - Hans-Peter Dürr! Es gelingt Dürr scheinbar mühelos, eine Synthese zwischen den meditativen Einsichten der Weisen des Ostens und den aktuellen Erkenntnissen der modernen Naturwissenschaften herzustellen. Dabei verliert er sich niemals in langatmigen akademischen Erläuterungen, sondern hat stets den Menschen und die gesellschaftliche Wirklichkeit des 21. Jahrhunderts im Blick. Ein Brückenschlag zwischen zwei Welten, der (...) vielleicht niemals notwendiger war als zurzeit. Eine kleines Meisterwerk, das in einleuchtender Weise aufzeigt - alles Leben ist EINS! (shrink)

Unsere Welt ist verschiedenartig. Nicht zuletzt wird das an den verschiedenen Religionen deutlich. Und doch ist unsere Welt eine Welt. Gemeinsam leben wir in ihr. Angesichts dieser Spannung kann gefragt werden: Wie konnen wir in unserer - auch religiosen - Unterschiedlichkeit in einer Welt zusammenleben? Und wie sollen wir das? Welche Moglichkeiten und Probleme bringen die Religionen an diesem Punkt mit sich? Der Band widmet sich diesen Fragen aus philosophischer und theologischer Sicht. Es werden ausgewahlte Modelle aus Philosophie und Theologie (...) vorgestellt und diskutiert, wie in unseren heutigen Gesellschaften religiose Pluralitat integriert werden kann und soll. (shrink)

One of the remarkable developments in the contemporary study of Paul is the dramatic interest in his thought amongst European philosophers. This collection of insights from leading scholars makes accessible a discussion often elusive to those not already conversant in the categories of European philosophy"--Publisher description.

English summary: Thinking about God is theology's main task and the philosophy of religion's most noble. Like almost no other theologian and philosopher of religion, Ingolf U. Dalferth's devotion to it has made the paradigms of current philosophical and theological theory construction fruitful. God, in whom people believe and place their trust, is revealed as the First and the Last, as the beginning without end, and the end that renews everything. This Festschrift's twenty-four studies pick up from Dalferth's work by (...) thinking about God in their own way. The richness of the questions they pose, the plurality of the answers, and the diversity of the religious-philosophical and theological perspectives affirm the worthiness of thinking God. German description: Gott zu denken, ist die zentrale Aufgabe der Theologie und die vornehmste der Religionsphilosophie. Wie kaum ein anderer Theologe und Religionsphilosoph hat sich Ingolf U. Dalferth dieser Aufgabe gewidmet und dafur die aktuellen Paradigmen philosophischer und theologischer Theoriebildung fruchtbar gemacht. Gott, an den Menschen glauben und auf den sie ihre Hoffnung setzen, kommt dem Denken als Erstes und Letztes in den Blick, als Anfang, der noch kein Ende gefunden hat, und als Ende, das alles neu macht.Die vierundzwanzig Studien dieser Festschrift nehmen Dalferths Beitrage auf, indem sie je auf ihre Weise Gott nachdenken. Der Reichtum der von ihnen diskutierten Fragestellungen, die Pluralitat der Antworten und die Vielfalt der religionsphilosophischen und theologischen Perspektiven bekraftigen die Denkwurdigkeit Gottes.

This book brings the poet and philosopher Novalis into dialogue with the work of Martin Heidegger, demonstrating that both should be understood principally as thinkers of relation.

Bei Nietzsches Texten handelt es sich häufig um Reaktionen auf seine breitgestreuten Lektüren. Sein Lesen ist zugleich ein Schreiben, und es verläuft ebenso selektiv und assoziativ wie aneignend: So werden unter Nietzsches Hand etwa Lesefrüchte aus naturwissenschaftlichen Lexika ästhetischen Überlegungen einverleibt oder ethno-anthropologische Fachbücher im Kontext philosophiegeschichtlicher Einordnungsversuche zitiert. Die Interpretation von Nietzsches Schriften ist daher stets auf eine philologisch-differenzierte Quellenarbeit angewiesen, die zugleich auch philosophisch-hermeneutischen Ansprüchen genügt. Nur so findet die spezifische Gemengelage aus Eigenem und Fremdem in Nietzsches Texten (...) ebenso adäquate Berücksichtigung wie die Vielzahl der handschriftlichen Lesespuren in den bis heute erhaltenen Büchern aus seiner persönlichen Bibliothek. In einer Reihe von Überblicksdarstellungen und exemplarischen Fallstudien unternimmt es der Band, Nietzsche im Spiegel seiner Lektüren als äußerst produktiven wie kreativen Leser zu charakterisieren, dessen Voraussetzungsreichtum nicht überschätzt werden kann.
