Constructibility and complexity play central roles in recent research in computer science, mathematics and physics. For example, scientists are investigating the complexity of computer programs, constructive proofs in mathematics and the randomness of physical processes. But there are different approaches to the explication of these concepts. This volume presents important research on the state of this discussion, especially as it refers to quantum mechanics. This `foundational debate' in computer science, mathematics and physics was already fully developed in 1930 in the (...) Vienna Circle. A special section is devoted to its real founder Hans Hahn, referring to his contribution to the history and philosophy of science. The documentation section presents articles on the early Philipp Frank and on the Vienna Circle in exile. Reviews cover important recent literature on logical empiricism and related topics. (shrink)

A structure has a (finite-string)automatic presentationif the elements of its domain can be named by finite strings in such a way that the coded domain and the coded atomic operations are recognised by synchronous multitape automata. Consequently, every structure with an automatic presentation has a decidable first-order theory. The problems surveyed here include the classification of classes of structures with automatic presentations, the complexity of the isomorphism problem, and the relationship between definability and recognisability.

While the Gödel centenary year 2006 triggered a lot of conference and workshop activity on Gödel, the years leading to it stand out by exhibiting several excellent publications on Gödel's life and work, most notably the completion of the Kurt Gödel Collected Works series . The two volumes of Kurt Gödel. Wahrheit & Beweisbarkeit, written in German and edited by E. Köhler et al., constitute something like the ‘German-Austrian contribution’ to this renewal of interest in Gödel's legacy, even though not (...) all of the articles in the volumes actually have German or Austrian authors.2 Indeed, as P. Weibel explains in the preface of the first volume, one of the intentions of the editors was to present Gödel as part of the cultural history of Austria. At the same time, the volumes highlight the contrast between Gödel's national reception—or lack thereof—and the way in which he was perceived and appreciated internationally, and although this discrepancy is now fortunately a thing of the past, its history is worth documenting. In this respect the two volumes will be of lasting value and importance, and the editors must be given credit not just for recording Gödel's delayed acceptance by Austrian politicians and university headquarters, but also for promoting Gödel's case. This being said, there is something extravagant and slightly queer about the two Kurt Gödel. Wahrheit & Beweisbarkeit volumes. Parts of them seem to be written for a generally educated audience, while other parts will be understandable only to logicians and philosophers who specialize in the topics covered. The volumes consist partly of biographical essays, interviews about Gödel, photos of him and his family, and letters by or to him, but they also include several non-historical articles which use ….

In this paper, I argue, first, that Hegel defended a version of the analytic/synthetic distinction—that, indeed, his version of the distinction deserves to be called Kantian. For both Kant and Hegel, the analytic/synthetic distinction can be explained in terms of the discursive character of cognition: insofar as our cognition is discursive, its most basic form can be articulated in terms of a genus/species tree. The structure of that tree elucidates the distinction between analytic and synthetic judgments. Second, I argue that (...) Hegel has an interesting and so far unexplored argument for the analytic/synthetic distinction: Hegel argues that the systematic relationship between concepts expressed in a genus/species tree can only be expressed through synthetic judgments. Third and finally, I explore some of the implications that the arguments in the first two parts of the essay have for understanding the way in which Hegel differs from Kant. I argue that Hegel accepts Kant's point that discursive cognition cannot be used to cognize the absolute. However, Hegel thinks that we can, nevertheless, cognize the absolute. I explore the character of this non-discursive cognition and argue that we can understand Hegel's glosses on this form of cognition—as simultaneously analytic and synthetic and as having a circular structure—through contrasting it with his account of discursive cognition. As a consequence, I argue that we must give up on attempts to understand ‘the dialectical method’ and ‘speculative cognition’ on the model of discursive cognition. (shrink)

English Summary: Although most religions claim peace as a goal to pursue, religions have been used as justification for violence again and again. Since September 11th, 2001 the Western and Eastern world has been confronted again with violence in the name of religion. As a fundamentalist understanding of religion is a fruitful basis for war and terror, it is essential to empower the liberal movements in the world religions, to support a peaceful community of people from different cultures and religions. (...) Therefore, it is of central importance for our own religious self-concept how faith and reason can be combined to make it possible to feel at home in our own religion and to welcome a pluralistic society. German description: Obwohl in den meisten Religionen Frieden als anzustrebendes Ziel gilt, wurden Religionen immer wieder zur Legitimation von Gewalt genutzt. Seit den Ereignissen des 11. September 2001 ist die westliche und ostliche Welt erneut konfrontiert mit der Gewalt im Namen der Religion. Insofern ein fundamentalistisches Religionsverstandnis den Nahrboden fur Krieg und Terror bildet, kommt es darauf an, die liberalen Krafte und Stromungen in den Weltreligionen zu starken, um ein friedliches Zusammenleben von Angehorigen verschiedener Kulturen und Religionen zu fordern. Fur das eigene religiose Selbstverstandnis ist daher von zentraler Bedeutung, wie Glaube und Vernunft so aufeinander bezogen werden konnen, dass es moglich ist, sowohl in der eigenen Religion beheimatet zu sein als auch die pluralistische Gesellschaft zu bejahen.

According to Kant, as far as the realisation of humanity is concerned, man is dependent on knowledge. But which science guarantees him an insight into what it means to be a human being? Philosophy? Anthropology? Philosophical anthropology? This study’s problem-oriented development of the question: ‘What is man?’ deals with the anthropological concepts of Scheler, Plessner, Portmann and Gehlen, drawing on the insights of classical philosophy. The focus of its critique is the biologism that is symptomatic of the failure of the (...) attempt to clarify the nature of man in comparative distinction to the form of existence of the animal. With reference to Herder, who understands man as a linguistic being, this book outlines the first steps on the path to overcoming the programme of modern anthropology through a form of ‘philosophy from language’.

Sind wir in unserem Denken, Entscheiden und Handeln frei? Diese Frage beschäftigt Menschen nicht erst seit der neueren Hirnforschung. Bereits die Römer kennen die Vorstellung eines willentlich handelnden Subjekts und haben daher den Begriff des Willens (voluntas) geprägt. Und auch die biblische Tradition von den Geboten Gottes, die der Mensch befolgen soll, legte einen solchen Gedanken nahe. Aus diesen Überlieferungssträngen schöpfend, verfasste der Kirchenvater Augustin seine Schrift De libero arbitrio (Über den freien Willen). Durch die weitere Theologie- und Philosophiegeschichte zieht (...) sich dann die Auseinandersetzung darüber, in welchem Mass der menschliche Wille frei bzw. unfrei ist. So bestritt etwa Luther gegen Erasmus die Willensfreiheit in Fragen des Heils. Die Beiträge des Bandes bedenken das Thema der Willensfreiheit jedoch nicht nur in theologischer und philosophischer Hinsicht, sondern beziehen auch biologische, psychologische und ethische Perspektiven mit ein, die den gegenwärtig geführten Debatten verpflichtet sind."-- Back cover.

"Rastafari practitioners have continually resisted social sciences definition of what outsiders called a millenarian movement. They maintained against these efforts of categorization that Rastafari as a lived and living philosophy combines ancient roots with ever emerging routes. These historical, dynamic and creative dimensions challenge any homogenizing attempts to freeze the 'movement' in time and space. African origins are as important as Diasporean experiences for Rastafari in the manifold struggles to downstroy slavery and oppression. But the strong universal appeal towards the (...) realization of equal rights and justice implodes analytical and practical limitations of a Black Atlantic culture. This volume brings together contributions from well-known Rastafari practitioners and social scientists as a counter to the unilateral politics of outside definition, identification, and misrepresentation. They discuss Rastafari as an experimental philosophy; its historical and contemporary global culture dimensions and its contribution to issues such as decolonization, reparation and repatriation. ".

Simon’s bounded rationality , the first scientific research program to seriously take the cognitive limitations of decision makers into account, has often been conflated with his more restricted concept of satisficing—choosing an alternative that meets or exceeds specified criteria, but that is not guaranteed to be unique or in any sense “the best.” Proponents of optimization often dismiss bounded rationality out of hand with the following “hallway syllogism” : bounded rationality “boils down to” satisficing; satisficing is “simply” a theory of (...) search for alternatives that takes into account the costs of computation. Hence, bounded rationality is “just a minor tweak” on optimal search theory. (shrink)

This paper reports on the findings of a qualitative study to understand how active adherence to the Christian faith influences the way SME owner-managers conceptualise their business practices. The study was based on in-depth interviews with 21 Christian SME owner-managers in Germany and the UK. Using a socio-psychological approach, the data analysis yielded a range of linguistic and conceptual resources that are peculiar to Christian discourse and that have the potential to influence business activity in rather distinctive ways. This paper (...) particularly focuses on those Christian concepts that could be regarded as distinct 'frames' for action. It outlines what effect these concepts had on the respondents and how they were related to business practices. The paper also discusses how this study could inform further research into the influence of other socio-cultural forms of identity on economic actors' conceptualisations of their own practice.

In his treatises A Defence of Common Sense, Proof of an External World, and Certainty, G.E. Moore wanted to put an end to the modern doubts about the certainty of reality and the ‘external world’ by pointing to the undeniable plausibilities of ‘empirical propositions,’ such as ‘I know that this is my hand’ or ‘I know that the earth had existed before my body was born.’ Wittgenstein, who was intensely grappling with Moore’s proofs during the last one and a half (...) years before his expected death, still questioned these proofs and countered them with his concept of language games – including a different logic of the ‘connection with reality.’ Philosophically, he thereby left many loose ends in all places and admittedly a ‘gap’ between them, which he was no longer able to close. But he prepared for closing the gap by means of his concept of orientation, which he had initiated in his Philosophical Investigations without defining it in this term. In a new interpretation of On Certainty from the perspective of the Philosophy of Orientation, this paper tries to show how the attention to the phenomenon of orientation and the language game in which it is expressed can close this gap and thus carry on Wittgenstein's late philosophy to a certain point.

In this paper, I argue for two principles to determine the temporal interpretation of modal sentences in English, given a theory in which modals are interpreted against double conversational backgrounds and an ontology in which possible worlds branch towards the future, The Disparity Principle requires that a modal sentence makes distinctions between worlds in the modal base. The Non- disparity Principle requires that a modal sentence does not make distinctions on the basis of facts settled at speech time. Selection of (...) the modal base will set these principles against each other, or allow for their cooperative interaction. For a root modal base, there is a conflict and disparity wins. The resulting interpretation is future. For a non-root modal base, the principles cooperate. Non-disparity determines a non-future interpretation and disparity requires the sentence to go beyond what is known by the speaker. (shrink)

In the twentieth century, Nietzsche became famous but remained infamous. No matter how popular his catchwords became, his thinking never acquired the status of a common philosophical ground like that of Aristotle, Descartes, or Kant. Most of our academic colleagues outside of Nietzsche research still hesitate to accept his ideas, not to mention adopting them. Our philosophical colleagues are primarily—and now more than ever—looking for secure logical and ontological, sometimes even metaphysical reasons, which Nietzsche impedes, if not entirely refuses. As (...) far as he was philosophically adopted and further developed—which happened primarily in France for a long time—such attempts were again reduced to narrow “-isms,”... (shrink)

The aim of this article is to show how the critically acclaimed and award winning film Margin Call may be used in business ethics teaching. Set in a fictional investment bank at the dawn of the financial crisis, the film zooms in on the motivations and decision-making of people who had much to lose from the crash of the hitherto very profitable mortgage-backed securities market. The film offers rich material for analysis of behaviours that contributed to the crisis. The article (...) will set out topics for classroom discussion, including the impact of incentives and power structures, contextual factors that distance people from the consequences of their actions, and considerations of how the banking industry may be transformed.

What is Europe, if it is not a geographical unit and still is not an economic and political unit? What is this Europe that has indulged in the excesses of war and mass murder up to the end of the 20th century, but wants to see itself as incorporating the ideals of justice and goodness? Europe was never simply 'Europe', it always questioned itself, it had to understand itself as Europe and thus found its unity in its philosophy. This book (...) looks forward to Europe's future with a new reading of key texts in Europe's modern philosophical reflection on itself. (shrink)

On the 25th anniversary of Berry’s historic papers on the geometric phase, I discuss here our neutron interferometry experiment in which this phase is clearly separated from the dynamical phase. The connection of this experiment to the observation of the sign reversal of the wave function of a fermion during a 2π precession in a magnetic field by three groups independently in 1975 is discussed.
