Aumann and Serrano :810–836, 2008) introduce the axiom of duality, which ensures that risk measures respect comparative risk aversion. This paper characterizes all dual risk measures by a simple equivalent condition. This equivalence provides a decomposition result and a construction method, which is used to analyze concrete dual measures. Moreover, this paper aims to extend this characterization to the most general setting. Compared with Aumann and Serrano, it, therefore, relaxes the axiom of positive homogeneity, and allows for risk-neutral and risk-seeking (...) agents, as well as for all integrable gambles. (shrink)

This book presents a multidisciplinary perspective on chance, with contributions from distinguished researchers in the areas of biology, cognitive neuroscience, economics, genetics, general history, law, linguistics, logic, mathematical physics, statistics, theology and philosophy. The individual chapters are bound together by a general introduction followed by an opening chapter that surveys 2500 years of linguistic, philosophical, and scientific reflections on chance, coincidence, fortune, randomness, luck and related concepts. A main conclusion that can be drawn is that, even after all this time, (...) we still cannot be sure whether chance is a truly fundamental and irreducible phenomenon, in that certain events are simply uncaused and could have been otherwise, or whether it is always simply a reflection of our ignorance. Other challenges that emerge from this book include a better understanding of the contextuality and perspectival character of chance (including its scale-dependence), and the curious fact that, throughout history (including contemporary science), chance has been used both as an explanation and as a hallmark of the absence of explanation. As such, this book challenges the reader to think about chance in a new way and to come to grips with this endlessly fascinating phenomenon. (shrink)

The present paper argues that, despite appearance to the contrary, Kierkegaard’s writings offer promising argumentational resources for addressing the problem of evil. According to Kierkegaard, however, in order to make use of these resources at all, one must necessarily be willing to shift the battleground, so to speak: from a third- to a genuine first-person perspective, namely the perspective of what Climacus dubs Religiousness A. All (yet also only) those who seek deliberate self-annihilation before God—a God in relation to whom (...) they perceive themselves always in the wrong—shall discover the ideal that an unwavering and in fact unconditional thankfulness (namely, for being forgiven) is to be considered the only appropriate attitude towards God and as such both necessary and sufficient for coming to terms with evil and suffering, at least in the life of someone making that discovery. I will argue that Kierkegaard’s (non-)pseudonymous writings provide reasons, at times unwittingly, for adopting the perspective of Religiousness A; however, I will also and ultimately argue that the principle of infinite thankfulness as a corollary of that perspective flounders when it comes to making sense of (the eschatological implications of) the suffering of others.

ZusammenfassungDieser Beitrag konzentriert sich auf eine starke und auf eine schwache Seite von Bayers Zugang zu Luthers Theologie. So wird als Stärke angesehen, dass das Thema der Rechtfertigung in Luthers Theologie als allumfassend angesetzt wird. Dagegen besteht eine Schwäche in der Art und Weise, wie Bayer durch Luthers Dialektik der zwei Arten, in denen Gott sich verbirgt – also verborgen »unter dem Gegenteil« und absolut verborgen – hindurch bricht, indem er die beiden trennt und diese Aufteilung als Kriterium verwendet, um (...) zwischen einer Periode, in der Luther die reformatorische Einsicht vollständig ausarbeitet, und einem vor-reformatorischen Luther zu unterscheiden. Diese Luther-Interpretation sollte nochmals überdacht werden, denn sie verneint die Entsprechung und die kontrapunktisch zu verstehende Beziehung zwischen dieser doppelten Verborgenheit im Lichte des »offenbaren Gottes«. Ein ähnliches Problem taucht dann auf, wenn Bayer die Rede vom dreieinigen Gott, die ausschließlich am Evangelium orientiert ist, unterscheidet von einer allgemeinen Art und Weise, von Gott zu reden, die allein auf dem Gesetz basiert. Luthers Vorstellung, dass die Unterscheidung zwischen Gesetz und Evangelium vollständig in Gottes Offenbarung des Evangeliums integriert ist, widerspricht einer solchen Unterscheidung. Dieser Beitrag betrachtet nicht nur die Unterscheidung zwischen einem unreifen und einem reifen Luther, der alle Implikationen der reformatorischen Einsicht ausgearbeitet hat, als unnötig, sondern er würdigt den jungen Luther als einen Theologen, der in der Lage ist, dasjenige zusammen zu halten, was beim späten Luther auseinander zu fallen droht. Glücklicherweise beinhaltet Bayers Studie auch Anknüpfungsmöglichkeiten für eine solche Interpretation Luthers, die die positiven ebenso wie die negativen Aspekte beider Arten der Verborgenheit ebenso wie Gesetz und Evangelium in einem einzigen kontinuierlichen Prozess integriert.SummaryThis contribution concentrates on one strong and one weak side of Bayer's approach to Luther's theology. It finds a strength in the universally implemented theme of justification in Luther's theological thought. A weakness is however found in the way Bayer breaks through Luther's dialectics concerning the dual way God hides himself – i. e. hidden ‘under the opposite’ and absolutely hidden – by separating them and using this division as a criterion to distinguish between the period where Luther had fully worked out the insight of the Reformation and the pre-Reformation Luther. Such an interpretation of Luther needs to be reconsidered because it neglects the correspondence and the contrapuntal relation between this double hiddeness in the light of the ‘revealed God’.A similar problem arises when Bayer divides speaking about the triune God, which is exclusively orientated towards the Gospel, from a general way of speaking about God, which is only based on the Law. Luther's idea that the distinction between Law and Gospel is fully integrated into God's revelation of the Gospel contradicts such a division.This contribution considers not only a distinction between an immature and a mature Luther who has worked out all the implications of the reformation insight unnecessary, but appreciates the young Luther as a theologian who is capable of holding together what the later Luther is in danger of letting fall apart. Fortunately, in Bayer's study there are also openings for a Luther interpretation that includes the positive as well as the negative aspect of both kinds of hiddeness and of Law and Gospel in a single continuous process.

This book studies the foundations of quantum theory through its relationship to classical physics. This idea goes back to the Copenhagen Interpretation (in the original version due to Bohr and Heisenberg), which the author relates to the mathematical formalism of operator algebras originally created by von Neumann. The book therefore includes comprehensive appendices on functional analysis and C*-algebras, as well as a briefer one on logic, category theory, and topos theory. Matters of foundational as well as mathematical interest that are (...) covered in detail include symmetry (and its "spontaneous" breaking), the measurement problem, the Kochen-Specker, Free Will, and Bell Theorems, the Kadison-Singer conjecture, quantization, indistinguishable particles, the quantum theory of large systems, and quantum logic, the latter in connection with the topos approach to quantum theory.

Most epistemologists hold that knowledge entails belief. However, proponents of this claim rarely offer a positive argument in support of it. Rather, they tend to treat the view as obvious and assert that there are no convincing counterexamples. We find this strategy to be problematic. We do not find the standard view obvious, and moreover, we think there are cases in which it is intuitively plausible that a subject knows some proposition P without—or at least without determinately—believing that P. Accordingly, (...) we present five plausible examples of knowledge without (determinate) belief, and we present empirical evidence suggesting that our intuitions about these scenarios are not atypical.

The integration of standardized biomedical terminologies into a single, unified knowledge representation system has formed a key area of applied informatics research in recent years. The Unified Medical Language System (UMLS) is the most advanced and most prominent effort in this direction, bringing together within its Metathesaurus a large number of distinct source-terminologies. The UMLS Semantic Network, which is designed to support the integration of these source-terminologies, has proved to be a highly successful combination of formal coherence and broad scope. (...) We argue here, however, that its organization manifests certain structural problems, and we describe revisions which we believe are needed if the network is to be maximally successful in realizing its goals of supporting terminology integration.

If one formulates Helmholtz’s ideas about perception in terms of modern-day theories one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts. Using constructs from statistical physics it can be shown that the problems of inferring what cause our sensory inputs and learning causal regularities in the sensorium can be resolved using exactly the same principles. Furthermore, inference and learning can proceed in a biologically plausible fashion. The ensuing scheme rests on (...) Empirical Bayes and hierarchical models of how sensory information is generated. The use of hierarchical models enables the brain to construct prior expectations in a dynamic and context-sensitive fashion. This scheme provides a principled way to understand many aspects of the brain’s organisation and responses. In this paper, we suggest that these perceptual processes are just one emergent property of systems that conform to a free-energy principle. The free-energy considered here represents a bound on the surprise inherent in any exchange with the environment, under expectations encoded by its state or configuration. A system can minimise free-energy by changing its configuration to change the way it samples the environment, or to change its expectations. These changes correspond to action and perception, respectively, and lead to an adaptive exchange with the environment that is characteristic of biological systems. This treatment implies that the system’s state and structure encode an implicit and probabilistic model of the environment. We will look at models entailed by the brain and how minimisation of free-energy can explain its dynamics and structure. (shrink)

English summary: German linguistics, formerly internationally inspiring, fell into a deep crisis at the beginning of the twentieth century. Since the First World War, those in the field have been looking for ways to regain its lost scientific and social recognition. This desire for relevance was particularly clear when practitioners of the different approaches to linguistic innovation competed for the scarce resources of public research funding. The remaining funding documents of the German Research Foundation demonstrate which specific linguistic approaches were (...) proclaimed as critical by researchers, and which were honored by outside funders during changing political contexts. Thus, the history of German philology and the development of its dynamics is here - for the first time - traced from the perspective of public support for research, from the time of the Weimar Republic until the first decades of the Federal Republic. German text. German description: Die ehemals international impulsgebende deutsche Sprachwissenschaft geriet am Anfang des zwanzigsten Jahrhunderts in eine tiefe Krise. Seit dem Ersten Weltkrieg suchte das Fach nach Wegen, die verlorene wissenschaftliche und gesellschaftliche Anerkennung wieder zu erlangen.Dieser Wille zur Relevanz zeigte sich besonders deutlich, wo die verschiedenen Neuerungsansatze der Sprachforschung um die knappen Mittel der staatlichen Forschungsforderung konkurrierten. An den erhaltenen Forderakten der Deutschen Forschungsgemeinschaft ist abzulesen, welche spezifischen Aufgabenstellungen die Sprachwissenschaft in wechselnden politischen Kontexten jeweils 'nach aussen' proklamierte und 'von aussen' honoriert bekam.So wird hier aus der Perspektive der staatlichen Forschungsforderung die Geschichte der deutschen Sprachforschung in ihrer Entwicklungsdynamik erstmals von der Weimarer Republik bis in die ersten Jahrzehnte der Bundesrepublik nachgezeichnet.

This is a review of the issue of randomness in quantum mechanics, with special emphasis on its ambiguity; for example, randomness has different antipodal relationships to determinism, computability, and compressibility. Following a philosophical discussion of randomness in general, I argue that deterministic interpretations of quantum mechanics are strictly speaking incompatible with the Born rule. I also stress the role of outliers, i.e. measurement outcomes that are not 1-random. Although these occur with low probability, their very existence implies that the no-signaling (...) principle used in proofs of randomness of outcomes of quantum-mechanical measurements should be reinterpreted statistically, like the second law of thermodynamics. In three appendices I discuss the Born rule and its status in both single and repeated experiments, review the notion of 1-randomness that in various guises was investigated by Kolmogorov and others and treat Bell’s Theorem and the Free Will Theorem with their implications for randomness.

This book addresses a seemingly marginal and as yet sparsely discussed policy problem that turns out to open a window into longstanding debates at the very heart of normative ethics, metaethics, and practical rationality more broadly: Should we contact the last uncontacted peoples? Over the course of this book, I will explore grounds for three responses to this question: yes, no, and rejecting the question. First, I aim to show that even though the case of uncontacted people stirs up some (...) hard problems for theories of justice and well-being, they still warrant a presumption in favour of intervention: It seems that we would have similar duties towards uncontacted people as we are regularly taken to have towards contacted people similarly placed – if being contacted would be good for them. And it looks as though it would be, based on considerations of welfare more broadly and reasons of autonomy in particular. Still, intuitively there seems to be a strong presumption against intervention – or so widely accepted policies of non-intervention would suggest. I go on to explore two options for why intervention may be wrong overall: It may turn out to be harmful or impermissibly risky upon closer inspection of contingent circumstances; or it may be that extinguishing uncontacted cultures is bad independently of the interests of those living in them. Two further options challenge the viability of the question: I consider whether the case of uncontacted peoples undermines the very bases of our moral judgments, perhaps instantiating what Bernard Williams sought to capture with the idea of a relativism of distance. Lastly, I address whether the question of one’s self-interest in this matter challenges practical rationality more fundamentally by being a transformative choice or one between incomparable options.

I argue that Bohmian mechanics cannot reasonably be claimed to be a deterministic theory. If one assumes the “quantum equilibrium distribution” provided by the wave function of the universe, Bohmian mechanics requires an external random oracle in order to describe the algorithmic randomness properties of typical outcome sequences of long runs of repeated identical experiments. This oracle lies beyond the scope of Bohmian mechanics, including the impossibility of explaining the randomness property in question from “random” initial conditions. Thus the advantages (...) of Bohmian mechanics over other interpretations of quantum mechanics, if any, must lie at an ontological level, and in its potential to derive the quantum equilibrium distribution and hence the Born rule.

In describing and classifying things we often rely on their modal characteristics. We will in general not have a satisfactory account of the nature and character of an object, unless we specify at least partly how the thing might be or cannot be, and also how it might have been or could not have been. In his contribution to the Second Jerusalem Philosophical Encounter,1 Strawson addressed the issue of how to understand such ascriptions of modal characteristics. Although his paper is (...) terse and provocative, and develops an intriguing account of modal predications, it has never received much attention in the philosophical literature. Recently, the issues dealt with in Strawson’s paper have become the subject of a widespread debate. Hence, we think it worthwhile to put Strawson’s account under closer scrutiny. In what follows, we first discuss his account of present tense ‘might’-statements, then his account of past perfect ‘might’-statements, and finally some essentialist remarks that he makes in his paper. That the discussion will be rather critical for the most part (though not exclusively so) should not belie the originality and inherent value of his pioneering approach. (shrink)

Statements about the behavior of biochemical entities (e.g., about the interaction between two proteins) abound in the literature on molecular biology and are increasingly becoming the targets of information extraction and text mining techniques. We show that an accurate analysis of the semantics of such statements reveals a number of ambiguities that have to be taken into account in the practice of biomedical ontology engineering: Such statements can not only be understood as event reporting statements, but also as ascriptions of (...) dispositions or tendencies that may or may not refer to collectives of interacting molecules or even to collectives of interaction events.

Eine Kritik der Hoffnung ist nicht nur nicht unzeitgemäß, sondern überhaupt zeitlos. Denn die existentielle Erfahrung, zu hoffen und enttäuscht zu werden, ist mit der menschlichen Situation untrennbar verknüpft. Der Grund, warum Schopenhauer als Gewährsmann einer solchen bemüht wird, ist, dass er vielfältige Ansätze dazu vorgelegt hat, die in diesem Buch zusammengefasst sind. Die vorliegende Untersuchung lässt sich in den größeren Rahmen von Schopenhauers «Pessimismus» einordnen, stellt aber den Begriff der Hoffnung in Nahaufnahme dar. Das Nachdenken über die Hoffnung vereinigt (...) Aspekte von Wahrheit und Irrtum, Wille und Intellekt, Wahrscheinlichkeit und Erwartung, und verdeutlicht die im Zusammenhang zwischen Sicherheit und Zweifel sich manifestierenden Seelenzustände von Hoffnung und Verzweiflung. Über Begriffsklärung und Analyse hinaus wird nach dem Wert oder Unwert der Hoffnung für das Leben gefragt. (shrink)

The pressures that led to the evolution of episodic memory have recently seen much discussion, but a fully satisfactory account of them is still lacking. We seek to make progress in this debate by taking a step backward, identifying four possible ways that episodic memory could evolve in relation to simulationist future planning—a similar and seemingly related ability. After distinguishing each of these possibilities, the paper critically discusses existing accounts of the evolution of episodic memory. It then presents a novel (...) argument in favor of the view that episodic memory is a by-product of the evolution of simulationist future planning. The paper ends by showing that this position allows for the maintenance of the traditional view that episodic memory operates on stored memory traces, as well as explaining a number of key features of episodic memory: its being subject to frequent and systematic errors, its neural co-location with the capacity for simulationist future planning, and the potential existence of non-human episodic memory.

Many philosophers have claimed that normative error theorists are committed to the claim ‘Error theory is true, but I have no reason to believe it’, which to some appears paradoxical. Case (2019) has claimed that the normative error theorist cannot avoid this paradox. In this paper, we argue that there is no paradox in the first place, that is once we clear up the ambiguity of the word ‘reason’, both on the error theorist’s side and those that claim that there (...) is a self-defeat problem. Upon clarification, we also raise scepticism to what exactly the nature of self-defeat is meant to be. (shrink)

Bell’s Theorem from Physics 36:1–28 (1964) and the (Strong) Free Will Theorem of Conway and Kochen from Notices AMS 56:226–232 (2009) both exclude deterministic hidden variable theories (or, in modern parlance, ‘ontological models’) that are compatible with some small fragment of quantum mechanics, admit ‘free’ settings of the archetypal Alice and Bob experiment, and satisfy a locality condition akin to parameter independence. We clarify the relationship between these theorems by giving reformulations of both that exactly pinpoint their resemblance and their (...) differences. Our reformulation imposes determinism in what we see as the only consistent way, in which the ‘ontological state’ initially determines both the settings and the outcome of the experiment. The usual status of the settings as ‘free’ parameters is subsequently recovered from independence assumptions on the pertinent (random) variables. Our reformulation also clarifies the role of the settings in Bell’s later generalization of his theorem to stochastic hidden variable theories. (shrink)

God is traditionally taken to be a perfect being, and the creator and sustainer of all that is. So, if theism is true, what sort of world should we expect? To answer this question, we need an account of the array of possible worlds from which God is said to choose. It seems that either there is (a) exactly one best possible world; or (b) more than one unsurpassable world; or (c) an infinite hierarchy of increasingly better worlds. Influential arguments (...) for atheism have been advanced on each hierarchy, and these jointly comprise a daunting trilemma for theism. In this paper, I argue that if theism is true, we should expect the actual world to be a multiverse comprised of all and only those universes which are worthy of creation and sustenance. I further argue that this multiverse is the unique best of all possible worlds. Finally, I explain how his unconventional view bears on the trilemma for theism. (shrink)

The growing scholarly debate on emotions and the development of Pentecostal and Charismatic churches in the Global South are just two reasons that urge systematic theology to relate more concretely to faith experiences. Potkay and others present joy as a typical Christian emotion, but it is not a key theme in systematic theology, although it plays far more prominent a role in spiritual and practical theological works. In this paper, the author presents the understandings of joy from the perspectives of (...) Blaise Pascal, A.A. van Ruler and Pentecostals from Ecuador and explores the implications for theological anthropology. Based on the study of these three perspectives, the author defends the thesis that joy offers a new focus in the field of theological anthropology that places different traditional theological perspectives on the human being in a fresh relation to each other and lays a foundation for a theological contribution to emotion studies.
