Evaluating clinical ethics support services has been hailed as important research task. At the same time, there is considerable debate about how to evaluate CESS appropriately. The criticism, which has been aired, refers to normative as well as empirical aspects of evaluating CESS. In this paper, we argue that a first necessary step for progress is to better understand the intervention in CESS. Tools of complex intervention research methodology may provide relevant means in this respect. In a first step, we (...) introduce principles of “complex intervention research” and show how CESS fulfil the criteria of “complex interventions”. In a second step, we develop a generic “conceptual framework” for “ethics consultation on request” as standard for many forms of ethics consultation in clinical ethics practice. We apply this conceptual framework to the model of “bioethics mediation” to make explicit the specific structural and procedural elements of this form of ethics consultation on request. In a final step we conduct a comparative analysis of two different types of CESS, which have been subject to evaluation research: “proactive ethics consultation” and “moral case deliberation” and discuss implications for evaluating both types of CESS. To make explicit different premises of implemented CESS interventions by means of conceptual frameworks can inform the search for sound empirical evaluation of CESS. In addition, such work provides a starting point for further reflection about what it means to offer “good” CESS. (shrink)

One of the most troubling and persistent challenges for Bayesian Confirmation Theory is the Problem of Old Evidence. The problem arises for anyone who models scientific reasoning by means of Bayesian Conditionalization. This article addresses the problem as follows: First, I clarify the nature and varieties of the POE and analyze various solution proposals in the literature. Second, I present a novel solution that combines previous attempts while making weaker and more plausible assumptions. Third and last, I summarize my findings (...) and put them into the context of the general debate about POE and Bayesian reasoning. (shrink)

The book gives an painstaking analysis of Niels Bohr's understanding of quantum mechanics based on a claim that Bohr was influenced by Harald Høffding's approach to philosophical problems.

This book provides the reader with an analysis of backward causation. The notion of backward causation faces many different paradoxes that threaten to make the notion inconsistent or incoherent. The book denies that these pose a real threat. It developed a theory of causation according to which the orientation of causation is not dependent on the direction of time. In this process it takes issues with David Lewis' contrafactual analysis of causation, and denies that the direction of time is determined (...) by irreversible processes . Likewise the book argues that the conceptual possibility of backward causation requires that the future is just as real as the past and present. Finally the book considers what the physical processes may look like if backward causation not only a a conceptual possibility but also a physical possibility. The conclusion is that no normal matter can possibly participate in backward causal processes. Instead objects moving backwards in time seem to posses negative mass and energy, a kind of objects that would be different from both ordinary objects and hypothetical tachyons. (shrink)

Nagarjuna's Vigrahavyavartani is one of the most important Madhyamaka Buddhist philosophical texts. Jan Westerhoff offers a new translation, reflecting the best current philological research and all available editions, and adds his own philosophical commentary on the text. His nuanced, philosophically sophisticated commentary explains Nagarjuna's arguments in a way that is both grounded in historical and textual scholarship and connected explicitly to contemporary philosophical concerns.

Students of Thomas Aquinas have so far lacked a comprehensive study of his doctrine of the transcendentals. This volume fills this lacuna, showing the fundamental character of the notions of being, one, true and good for his thought. The book inquires into the beginnings of the doctrine in the thirteenth century and explains the relation of the transcendental way of thought to Aquinas's conception of metaphysics. It analyzes 'Being', 'One', 'True', 'Good' and 'Beautiful' individually and discusses their importance for the (...) philosophical knowledge of God. Medieval Philosophy and the Transcendentals: The Case of Thomas Aquinas is intended as a contribution to the question 'What is philosophy in the Middle Ages?' It argues that the doctrine of the transcendentals is essential for understanding medieval philosophy. (shrink)

The mind–body problem is analyzed in a physicalist perspective. By combining the concepts of emergence and algorithmic information theory in a thought experiment, employing a basic nonlinear process, it is shown that epistemologically emergent properties may develop in a physical system. Turning to the significantly more complex neural network of the brain it is subsequently argued that consciousness is epistemologically emergent. Thus reductionist understanding of consciousness appears not possible; the mind–body problem does not have a reductionist solution. The ontologically emergent (...) character of consciousness is then identified from a combinatorial analysis relating to universal limits set by quantum mechanics, implying that consciousness is fundamentally irreducible to low-level phenomena.

We introduce a cyclic proof system for the two-way alternation-free modal μ-calculus. The system manipulates one-sided Gentzen sequents and locally deals with the backwards modalities by allowing analytic applications of the cut rule. The global effect of backwards modalities on traces is handled by making the semantics relative to a specific strategy of the opponent in the evaluation game. This allows us to augment sequents by so-called trace atoms, describing traces that the proponent can construct against the opponent’s strategy. The (...) idea for trace atoms comes from Vardi’s reduction of alternating two-way automata to deterministic one-way automata. Using the multi-focus annotations introduced earlier by Marti and Venema, we turn this trace-based system into a path-based system. We prove that our system is sound for all sequents and complete for sequents not containing trace atoms. (shrink)

_Vygotsky Philosophy and Education_ reassesses the works of Russian psychologist Lev Vygotsky work by arguing that his central ideas about the nature of rationality and knowledge were informed by the philosophic tradition of Spinoza and Hegel.

This paper synthesizes confirmation by instances and confirmation by successful predictions, and thereby the Hempelian and the hypothetico-deductive traditions in confirmation theory. The merger of these two approaches is subsequently extended to the piecemeal confirmation of entire theories. It is then argued that this synthetic account makes a useful contribution from both a historical and a systematic perspective.

Friis and Crease illustrate the diversity of content and styles in postphenomenology, a burgeoning field that has attracted attention among scholars engaged in technology studies. Contributors to this edited collection seek to analyze, clarify, and develop postphenomenological language and concepts, expand the work of Don Ihde, the field's founder, and delve into areas that Ihde never tackled.

The notion of “conception” plays a central role in Thomas Reid’s theory of perceptual knowledge, although “conception” might be studied for itself as a source of knowledge. In this study, we attempt to expose systematically the several contexts where Reid deals with the source of knowledge and the kind of mental operation called “conception”. The purpose is to understand a specific aspect of the deliverances of “conception” in Reid’s theory of perception, namely, a direct relationship, not mediated by ideas, between (...) knowing subject and external world. To understand the operation of conceiving, which is intrinsic to and constitutive of perception, is an efficient way to comprehend the nature and content of perceptual knowledge. At this step, reflections on the relationship between mind and external world, that is, mind and material world, have to be made. (shrink)

This paper makes the case for a sharper terminology regarding AIs cognitive abilities. In arguing that thinking requires more than content production, I offer a definition of meaning drawing on a clear distinction between living and machine intelligence. A pivotal argument is the re-use of the Turing Test (TT) for understanding which theories of meaning and consciousness are no longer plausible—because they have been reproduced by software without thereby gaining conscious experience. In following the few theories that have not (yet) (...) failed this reversed Turing Test (RTT), the focus turns towards rethinking the human condition in times of AI along the lines of three questions: What if a machine developed consciousness? What if AI proceeded without developing a consciousness? What, if machinic and human intelligence merged? These three questions in the end lead to examining three related possible futures of humanism as now determined by the relation between Human Intelligence and AI. (shrink)

The limiting of violence through state powers is one of the central projects of the modern age. Why then have recent centuries been so bloody? In Trust and Violence, acclaimed German intellectual and public figure Jan Philipp Reemtsma demonstrates that the aim of decreasing and deterring violence has gone hand in hand with the misleading idea that violence is abnormal and beyond comprehension. We would be far better off, Reemtsma argues, if we acknowledged the disturbing fact that violence is normal. (...) At the same time, Reemtsma contends that violence cannot be fully understood without delving into the concept of trust. Not in violence, but in trust, rests the foundation of true power. Reemtsma makes his case with a wide-ranging history of ideas about violence, from ancient philosophy through Shakespeare and Schiller to Michel Foucault, and by considering specific cases of extreme violence from medieval torture to the Holocaust and beyond. In the midst of this gloomy account of human tendencies, Reemtsma shrewdly observes that even dictators have to sleep at night and cannot rely on violence alone to ensure their safety. These authoritarian leaders must trust others while, by means other than violence, they must convince others to trust them. The history of violence is therefore a history of the peculiar relationship between violence and trust, and a recognition of trust's crucial place in humanity. A broad and insightful book that touches on philosophy, sociology, and political theory, Trust and Violence sheds new, and at times disquieting, light on two integral aspects of our society.

There is a lot of talking and writing on virtues and education nowadays. In spite of this, a clear and convincing account of the defining characteristics of the virtue approach to moral education is still lacking. This paper suggests and discusses three different definitions of such an approach. With reference to each definition it is examined whether the virtue approach can be distinguished from other main perspectives on moral education, in particular from the so-called cognitive-developmental approach (including the just community (...) approach). It is argued that only the definition that refers to an ethics of virtue will have the required differentiating capacity. (edited). (shrink)

We represent consensus formation processes based on iterated opinion pooling as a dynamic approach to common knowledge of posteriors :1236–1239, 1976; Geanakoplos and Polemarchakis in J Econ Theory 28:192–200, 1982). We thus provide a concrete and plausible Bayesian rationalization of consensus through iterated pooling. The link clarifies the conditions under which iterated pooling can be rationalized from a Bayesian perspective, and offers an understanding of iterated pooling in terms of higher-order beliefs.

Masaryk’s philosophical approach to reality is largely characterised by its orientation towards the positivism of Auguste Comte, which Masaryk sought to offset with the psychologism of J. S. Mill. The combination of these positivist approaches became the positive starting point for Masaryk’s ethics. But that was not the only influence on his ethics. Masaryk’s German translation of Hume’s book, titled Eine Untersuchung über die Prinzipien der Moral von David Hume (1883), reveals that the main stimuli that shaped Masaryk’s ideas about (...) ethics came from David Hume. Although the need for scientific evidence became a fundamental principle of Masaryk’s thought, the need to objectively anchor ethics in rational theism necessitated in this area a departure from his positivist outlook. Masaryk’s lectures on practical philosophy attest to this fact. The reason for his departure from a positivist stance was due to the metaphysical nature of his concept of psychology. (shrink)

This paper argues that there are practical problems of such a kind that neither impartial morality nor rational choice theory can provide us with comfort and guidance in our attempt to make the right choice if confronted with such a problem. It argues that both morality and rational choice theory are bound to misconstrue problems of this kind. Appreciating the limits of both morality and rational choice theory, as currently discussed in the literature (Wolf, Morton, Pettit, Hollis & Sugden), enables (...) us to identify the features of these particular practical problems, and allows us to elaborate the idea of an alternative of oneself, which is crucial to a proper understanding of the kind of practical problem the paper draws attention to.

Neste estudo, dá-se continuidade à exposição do scotismo do mestre franciscano chileno Alfonso Briceño (1587-1668), pondo a ênfase em um de seus cinco Apêndices Metafísicos, que constam em suas Controversiae (Madri, 1639-1642). No terceiro Apêndice Metafísico, após expor o conceito metafísico de “distinção”, após apresentar a sua doutrina da “distinção de razão” e após uma digressão sobre a “distinção precisiva”, Briceño dá início à sua apresentação da “distinção real”, da qual a “distinção formal” será um tipo especial e particularmente controverso. (...) Passo intermediário para a compreensão da distinção formal é uma breve exposição dos tipos de distinção real e uma discussão articulada sobre um tipo especial de “distinção modal” na escola scotista. O significado e a importância dessa distinção na metafísica scotista de Alfonso Briceño são o enfoque deste estudo. (shrink)

The paper presents some basic tenets of the works by the Franciscan Friar Alfonso Briceño (1587–1668), as well as of his metaphysical thought. After offering the basic structure and purpose of his monumental Controversiae, we focus on a more specific way of seeing his philosophical and theological approach, namely Controversy 5 on the infinity of God. This will allow us to see the structure of his argumentation in philosophy and theology: after putting the formulation of controversial points between the Scotist (...) and the Thomist school, he analyzes arguments against the Thomist position both in the Medieval and Baroque traditions, trying then to defend Duns Scotus’s account by a careful and articulated interpretation of his texts.

This paper investigates the Democritean account of human nature and sociability. After briefly discussing what the claim that human beings are social animals means, the paper analyzes two culture stories, preserved in Diodorus of Sicily and John Tzetzes, that are typically taken to be Democritean, arguing that there are prima facie significant differences between the two accounts. The paper then concludes that human beings are not social animals by nature on the Democritean view, but rather that the Democritean account belongs (...) to a different, that is, non-Aristotelian and non-Stoic, tradition of social thought.

The philosophy of the humanistic sciences has been a blind-spot in analytic philosophy. This book argues that by adopting a pragmatic analysis of explanation and interpretation it is possible to show that scientific practice of humanistic sciences can be understood on similar lines to scientific practice of natural and social sciences.

Im Zentrum des vorliegenden Sammelbandes steht die Frage nach dem Bösen in Religionen, die als monotheistisch verstanden werden oder für die zumindest die Herrschaft des Hauptgottes über alle anderen Götter und Mächte ein entscheidendes Anliegen ist. Der Schwerpunkt liegt auf dem sich formierenden Judentum und Christentum sowie dem Alten Testament. Besonderes Interesse gilt den Texten aus Qumran, und darüber hinaus erfolgt ein Blick auf mittelalterliche Heiligenlegenden. Die Beiträge des Bandes zeigen, dass es in den antiken jüdischen und christlichen Texte eine (...) große Vielfalt von Verkörperungen des Bösen gibt, sei es extern als Dämon oder Teufel, sei es intern als die menschliche Fähigkeit, Böses zu tun. Außerdem stellt sich heraus, dass in der jüdisch-christlichen Literatur Dualismus nicht grundsätzlich abgelehnt wird, aber nur Formen von Dualismus vorkommen, in denen das Böse Gott und dem Guten letztlich untergeordnet ist. Mit Beiträgen von: Jörn Bockmann, Miryam T. Brand, Jan Dochhorn, Matthew Goff, Erkki Koskenniemi, Michael Morris, Hector M. Patmore, Susanne Rudnig-Zelt, Markus Saur, Ryan E.

Crime and gentrification are among the most hotly-contested urban issues in American cities. In Us versus Them, Jan Doering examines both, showing how residents, activists, and politicians clashed over these issues and especially over how race factored into both. The book draws on extensive fieldwork to produce a comprehensive and vivid portrait of community conflict in two racially-diverse Chicago neighborhoods. In doing so, it provides new insights into how residents use the criminal justice system to fight crime but advance gentrification (...) in the process. (shrink)
