This article suggests a ‘best alternative' justification of induction (in the sense of Reichenbach) which is based on meta-induction . The meta-inductivist applies the principle of induction to all competing prediction methods which are accessible to her. It is demonstrated, and illustrated by computer simulations, that there exist meta-inductivistic prediction strategies whose success is approximately optimal among all accessible prediction methods in arbitrary possible worlds, and which dominate the success of every noninductive prediction strategy. The proposed justification of meta-induction is (...) mathematically analytical. It implies, however, an a posteriori justification of object-induction based on the experiences in our world. *Received November 2005; revised March 2008. †To contact the author, please write to: Department of Philosophy, University of Duesseldorf, Universitaetsstrasse 1, Geb. 23.21, Duesseldorf, Germany D-40225; e-mail: gerhard[email protected].

The notions of common knowledge or common belief play an important role in several areas of computer science , in philosophy, game theory, artificial intelligence, psychology and many other fields which deal with the interaction within a group of “agents”, agreement or coordinated actions. In the following we will present several deductive systems for common knowledge above epistemic logics –such as K, T, S4 and S5 –with a fixed number of agents. We focus on structural and proof-theoretic properties of these (...) calculi. (shrink)

By “the” modal fallacy one commonly means the following argument pattern.

This paper is intended as a contribution to a recent vigorous debate inThe Times, between the distinguished journalist Bernard Levin, the eminent Oxford economist Wilfred Beckerman and the Archbishop of York, John Habgood, among others. The debate concerns morality, ‘free will’ and determinism. As a former German Jew, who lost close relatives at Auschwitz and who suffered personally severely in my youth under daily virulent Nazi persecution, I obviously cannot remain strictly detached and neutral. Yet, I shall attempt to retain (...) as much neutrality as possible, since I think that the main rivals in this debate have all some very relevant, interesting and valid things to say. Let me also state other, probably very relevant, biases. I am an ardent Zionist. In addition, I am a diehard mechanistic materialist as regards basic philosophy, although I am tolerant of other people's religious feelings, because I realize that my materialism is as metaphysical as their religious views. With this as background let me return to the technical issues. Obviously, in a philosophical journal one can write at a level above that ofThe Times, where there is, perhaps, insufficient room to debate philosophical, biological, physical and other niceties in some depth.

Im Zentrum der Hauptform des metaethischen Relativismus steht eine kontextualistische Analyse der Bedeutung moralischer Aussagen. Gegen diese Analyse lassen sich jedoch bestimmte sprachliche Beobachtungen anführen, die der Relativist erklären muss, wenn er an seiner Theorie festhalten möchte. In diesem Aufsatz argumentiere ich für die These, dass keiner dieser Erklärungsversuche gelingt. Wir betrachten, wie sich zeigt, moralische Aussagen als weder in offensichtlicher noch in versteckter Weise kontextsensitiv. Damit gerät aber der Relativismus als metaethische Position überhaupt in ernsthafte Bedrängnis.

In recent years Donald Davidson has outlined main features of a "unified theory" of language and action. The article tries to lay open the central theoretical steps one has to take from his "radical interpretation" to his theory of rationality and his triangulation model of externalism. It is argued that Davidson's reinterpretation of Tarski's T - sentences can be used to show a fundamental symmetry between representation and expression of propositional contents. Yet, his theoretical framework has to be enriched to (...) deal with the problem of contextualism that arises from his redescription of utterance meanings. The paper shows in order to elaborate Davidson's claim that rationality is a normative concept one has to address the question of an internal relationship between radical interpretation, rationality and externalism.

The paper gives a reconstruction of Donald Davidson’s theory of primary reasons in the context of the unified theory of meaning and action and its ontology of individual events. This is a necessary task to understand this philosophy of language and action because since his article “Actions, Reasons, and Causes” he has developed and modified his proposal on describing and explaining actions. He has expanded the “unified theory” to a composite theory of beliefs and desires as a total theory of (...) behavior. At first, the anomalous monism was a byproduct. Yet, the step to this philosophy of the mental is not contingent. It will be shown that the anomalous monism as the primary feature of the mental does not lead us to a materialic monism in our ontology. If the evidence of radical interpretation has no echo in natural science, we have to give up materialism.Following this, I will argue for a pure anomalism. Or, in other words, for the ascription of propositional attitudes given by the semantical analysis of sentences of such attitudes does not commit us to a materialistc framework in our ontological thinking. Yet, to understand Davidson’s unified theory, we have to grasp the role of individual events in this framework since the ontological reduction of individual events explains par example the relation between the mind and the body, and the possibility of autonomous action in the world of causality. I do not argue for a dualism of properties between the physical of the mental in the manner of other philosophers, since from the radical interpreters point the empirical restrictions of the speaker’s attitudes and behavior cannot be fixed for all cases.

The main theme of Hilary Putnam’s philosophy is the problem of realism. But to discuss his position in the debate on natural kind terms, his criticism of logical empirism and Tarki’s theory of truth, a reconstruction of his „theoretical framework“ (Rahmentheorie) is required. The best characterization of this „theory“ concerns the oppositon: theoretical names (theory of understandig, fixing reference by experts of linguistic division of labour) versus empirical pragmaticism (truth, reference i.e. the successful patterns of linguistic behaviour). In this context (...) we can identify the problems of Putnam’s philosophical orientation: his „main theme“ of revitalizing realism. The following step is to expose in the context of „radical interpretation“ a position, which may be dubbed „radical contextualism“. This may be seen as an alternative position to both realism and anti-realism. (shrink)

ZusammenfassungAls Folge der voranschreitenden Digitalisierung und der COVID-19 Pandemie steigt die Nachfrage nach Indoor-Cycling Plattformen wie ‘Peloton’ exponentiell. Das Ziel dieses Beitrags ist es zu untersuchen, welche Faktoren die Nutzung von Indoor-Cycling Plattformen nachhaltig beeinflussen. Dafür wurde auf Basis der ‚Unified Theory of Acceptance and Use of Technology‘ ein kontextspezifisches Forschungsmodell abgeleitet, das auf Grundlage einer Befragung von 313 Nutzer/innen und des über die Plattform gemessenen Nutzungsverhaltes, überprüft wurde. Die extrinsische Motivation wird insbesondere durch die Trainingsmöglichkeiten getrieben, während Unterstützung durch (...) Trainer/innen der Haupttreiber der intrinsischen Motivation ist. Soziale Interaktion beeinflusst beide Motivationsformen gleichermaßen. Intrinsische und extrinsische Motivation stellen starke Prädiktoren der Nutzungsintention dar, die wiederum nur mäßig die tatsächliche Nutzung beeinflusst, sodass sich Folgestudien stärker auf Barrieren der Nutzung fokussieren sollten. Die Multigruppenanalyse zeigt, dass der Zusammenhang zwischen Unterstützung durch Trainer/innen und extrinsischer sowie intrinsischer Motivation bei Männern signifikant höher ausgeprägt ist, als bei Frauen. Bei Frauen ist hingegen der Zusammenhang zwischen sozialer Interaktion und intrinsischer Motivation stärker ausgeprägt. (shrink)
