We generalize the concept of Nash equilibrium in mixed strategies for strategic form games to allow for ambiguity in the players' expectations. In contrast to other contributions, we model ambiguity by means of so-called lower probability measures or belief functions, which makes it possible to distinguish between a player's assessment of ambiguity and his attitude towards ambiguity. We also generalize the concept of trembling hand perfect equilibrium. Finally, we demonstrate that for certain attitudes towards ambiguity it is possible to explain (...) cooperation in the one-shot Prisoner's Dilemma in a way that is in accordance with some recent experimental findings.

We define an evolutionary process of “economic Darwinism” for playing the field, symmetric games. The process captures two forces. One is “economic selection”: if current behavior leads to payoff differences, behavior yielding lowest payoff has strictly positive probability of being replaced by an arbitrary behavior. The other is “mutation”: any behavior has at any point in time a strictly positive, very small probability of shifting to an arbitrary behavior. We show that behavior observed frequently is in accordance with “evolutionary equilibrium”, (...) a static equilibrium concept suggested in the literature. Using this result, we demonstrate that generally under positive (negative) externalities, economic Darwinism implies even more under- (over-)activity than does Nash equilibrium. (shrink)
This paper uses a two-dimensional version of a standard common consequence experiment to test the intransitivity explanation of Allais-paradox-type violations of expected utility theory. We compare the common consequence effect of two choice problems differing only with respect to whether alternatives are statistically correlated or independent. We framed the experiment so that intransitive preferences could explain violating behavior when alternatives are independent, but not when they are correlated. We found the same pattern of violation in the two cases. This is (...) evidence against intransitivity as an explanation of the Allais Paradox. The question whether violations of expected utility are mainly due to intransitivity or to violation of independence is important since it is exactly on this issue the main new decision theories differ.

Résumé — Cet article se propose d’explorer les thèses d’Adorno sur les thèmes de la solidarité et de la métaphysique, au moment où ces derniers perdent de leur importance. Le point de vue qu’Adorno défend de façon réactionnaire peut être qualifié de « métaphysique de la sécularisation ». Cette prise de position a joué un rôle crucial dans son opposition au capitalisme tardif, au nominalisme, au positivisme et plus généralement à la prohibition de la réflexion. L’article développe enfin les affinités (...) et les différences fondamentales entre les idées d’Adorno concernant la métaphysique et la perspective critique de Heidegger sur ce sujet, dans un contexte de décadence de la métaphysique classique.— The article investigates Adorno’s idea concerning solidarity towards the metaphysics at the moment when it collapses. The position which he indignant defends could be called metaphysics in secularization. It plays a part in his showdown with late capitalism, nominalism, positivism and in general the prohibition against thinking. The article furthermore shows the affinity but also the essential difference between Adorno’s idea concerning metaphysics after the breakdown of the classical metaphysics and Heidegger’s criticism of the metaphysics.

The aim of this paper is to elaborate on the phenomenological approach to expertise as proposed by Dreyfus and Dreyfus and to give an account of the extent to which their approach may contribute to a better understanding of how athletes may use their cognitive capacities during high-level skill execution. Dreyfus and Dreyfus's non-representational view of experience-based expertise implies that, given enough relevant experience, the skill learner, when expert, will respond intuitively to immediate situations with no recourse to deliberate actions (...) or mental representations. The paper will subsequently outline some implications and consequences of such an approach and will also examine to what extent Dreyfus and Dreyfus's skill model is capable to resist different attacks that have been made against their view, and in particular regarding the practical application of their approach to the skill domain of competitive sport.

This article provides a survey of key topics on just inheritance taxation. It does so by first presenting the main arguments in the debate. Here, I distinguish between arguments in the academic literature and the various arguments which have proven important in the public debate. Secondly, I outline four influential proposals when it comes to how inheritance should be taxed. Finally, I examine a recent controversy and point towards a number of themes that have not been sufficiently discussed.
Given the prominent position Habermas' philosophy has gained, it is surprising that his method, rational reconstruction, has not caused more debate. This article clarifies what this method consists of, and shows how it is used in two of Habermas' research programs. The method is an interesting, but problematic way of confronting some of the basic epistemological questions in the social sciences. It represents an alternative to both the empirical-analytical and the hermeneutic tradition. On the basis of this methodology, Habermas' work (...) is situated between the transcendental and the empirical approach. A fundamental problem is that it remains unclear how to test the hypothesis put forward through rational reconstruction. (shrink)
The philosophical situation at Copenhagen University in the 1960’s was dominated by two positivists. Th elogical positivist Jørgen Jørgensen – who had written the history of the “movement” – and the legal positivistAlf Ross. There were also two “outsiders”: Peter Zinkernagel, who did more analytical philosophy of language in the British style, and K. Grue Sørensen who was working in the traditions of neo-Kantianism. In 1955 Grue-Sørensen was hired as the first professor in education – after a long controversy about (...) the scientific status ofeducation as a discipline – but with a focus on the history of education. He had received a doctoral degree in philosophy in 1950 with a dissertation on refl exivity as a philosophical concept and a thesis about the reflexivity of consciousness. He was also an objectivist in ethics, and had been critical of the prevalent moral relativism and subjectivism found in recent philosophy. Jørgensen and Ross had done important work on moral argumentation with more technical work on the logic of imperatives and norms. Moral objectivism was not only wrong but in a way also “immoral” because it undermined their belief in democracy. Especially Jørgensen also thought that the idea of reflexivity was wrong when applied to consciousness. Neither statements nor consciousness could be reflexive – that is refer to themselves/itself. The reflexivity of consciousness is – according to Jørgensen – simply not an empirical psychological fact. Grue-Sørensen tried to establish the foundation of a theory of education based both on conceptions of consciousness and of the relation between scientific knowledge – facts – and moral values – in a neo-Kantian fashion. For him the interplay between ethics and knowledge was a central part of a theory of education – a belief due to which he never became a professor of philosophy – having tried many times. These debates in philosophy and in education were superseded in the 1970’s by the rise in influence of the German inspiration from Critical Theory and the demise of logical positivism. (shrink)
Jürgen Habermas’s theories have received enormous attention in the public sphere as well as in political science. It is therefore surprising that his method, rational reconstruction, is not more debated. In political science the method is of particular interest because of its ambition to bridge the gap between empirical and normative approaches. In this article the author traces Habermas’s interest in rational reconstruction by going back to his writings on theory and practice and subsequently shows what the method’s main principles (...) are. He then specifies how this methodological conception is used in Habermas’s political theory. Finally, the introduction of an empirical design allows the author to discuss one of the fundamental tensions in Habermas’s approach: the hypotheses arrived at through rational reconstruction are empirical hypotheses but cannot be tested by empirical means.

We have investigated the effects of organic content and maturation on the elastic properties of source rock shales, mainly through integration of a well-log database from the Central North Sea and associated geochemical data. Our aim is to improve the understanding of how seismic properties change in source rock shales due to geologic variations and how these might manifest on seismic data in deeper, undrilled parts of basins in the area. The Tau and Draupne Formations in immature to early mature (...) stages exhibit variation mainly related to compaction and total organic carbon content. We assess the link between depth, acoustic impedance, and TOC in this setting, and we express it as an empirical relation for TOC prediction. In addition, where S-wave information is available, we combine two seismic properties and infer rock-physics trends for semiquantitative prediction of TOC from [Formula: see text] and AI. Furthermore, data from one reference well penetrating mature source rock in the southern Viking Graben indicate that a notable hydrocarbon effect can be observed as an addition to the inherently low kerogen-related velocity and density. Published Kimmeridge shale ultrasonic measurements from 3.85 to 4.02 km depth closely coincide with well-log measurements in the mature shale, indicating that upscaled log data are reasonably capturing variations in the actual rock properties. Amplitude variation with offset inversion attributes should in theory be interpreted successively in terms of compaction, TOC, and maturation with associated generation of hydrocarbons. Our compaction-consistent decomposition of these effects can be of aid in such interpretations. (shrink)
The traditional square of opposition is generalized and extended to a cube of opposition covering and conveniently visualizing inter-sentential oppositions in relational syllogistic logic with the usual syllogistic logic sentences obtained as special cases. The cube comes about by considering Frege–Russell’s quantifier predicate logic with one relation comprising categorical syllogistic sentence forms. The relationships to Buridan’s octagon, to Aristotelian modal logic, and to Klein’s 4-group are discussed.GraphicThe photo shows a prototype sculpture for the cube.

Immanuel Kant’s essay on Perpetual Peace contains a rejection of the idea of a world government. In connexion with a substantial argument for cosmopolitan rights based on the human body and its need for a space on the surface of the Earth, Kant presents the most rigorous philosophical formulation ever given of the limitations of the cosmopolitan law. In this contribution, Kant’s essay is analysed and the reasons he gives for these restrictions discussed in relation to his main focus: to (...) project a realistic path to perpetual peace. (shrink)
To this day, an adequate interpretation in English of Fichte’s entire philosophy is lacking. Even Frederick Copleston, whose sixty-two pages on Fichte in his History of Philosophy I should recommend as the best general introduction so far available, capitulates at the end before the task of seeing a unity in the thought of this philosopher.
The Rawls–Habermas debate is having a revival. In this article I argue that both philosophers develop different freestanding conceptions of political legitimacy, and show how they diverge when it comes to how political legitimacy can be justified. Habermas is looking for a deeper justification than Rawls will allow for. I then proceed to show how the different meta-ethical positions yield two different versions of democratic theory, focusing in particular on rights and popular sovereignty. I demonstrate how both conceive of the (...) co-originality of private and public autonomy, and subsequently take issue with Habermas’ reading of Rawls. I argue that Rawls should not be understood as a natural rights theorist, that Habermas misunderstands the role of the original position, and that Rawls cannot be considered a strong constitutionalist. Thus, the real difference between Rawls and Habermas revolves around their different conceptions of political legitimacy. (shrink)
Social philosophy is a somewhat broad and imprecise term. In this article I discuss the social philosophy of Habermas, Foucault and Honneth, arguing that the latter’s work is an interesting, but not unproblematic, conception of the discipline. Following Habermas and Honneth, I argue that social philosophy should be reconstructive, but incorporate insights from Foucault. Specifically, reconstructive social philosophy can be both normative and descriptive, and at the same time establish a dialectical relationship between philosophy and the social sciences, thus fulfilling (...) the ambition for social philosophy originally put forward by Horkheimer. The thesis I defend in this article is that reconstructive social philosophy in Habermasian or Honnethian fashion has the resources available to accomplish this ambitious task. (shrink)
Memory is a general attribute of living species, whose diversification reflects both evolutionary and developmental processes. Episodic-autobiographical memory is regarded as the highest human ontogenetic achievement and as probably being uniquely human. EAM, autonoetic consciousness and the self are intimately linked, grounding, supporting and enriching each other’s development and cohesiveness. Their development is influenced by the socio-cultural–linguistic environment in which an individual grows up or lives. On the other hand, through language, textualization and social exchange, all three elements leak into (...) the world and participate to the dynamic shaping and re-shaping of the cultural scaffolding of the self, mental time traveling and EAM formation. Deficits in self-related processing, autonetic consciousness, emotional processing and mental time traveling can all lead to or co-occur with EAM disturbances, as we illustrate by findings from EAM impairments associated with neurological or psychiatric disorders.

Intuition has increasingly been considered as a legitimate foundation for decision-making, and the concept has started to find its way into military doctrines as a supplement to traditional decision-making procedures, primarily in time-constrained situations. Yet, absent inside the military realm is a critical and level-headed discussion of the ethical implications of intuitive behaviour, understood as an immediate and situational response with no recourse to thoughtful or deliberate activity. In this article the author turns to phenomenological philosophy, and in particular to (...) the works of Hubert and Stuart Dreyfus, to elaborate on the ethical implications and consequences of intuitive behaviour. Dreyfus and Dreyfus understand moral behaviour as a skill, and as such they claim that it is possible to develop this capability through practice. They even claim that intuitive behaviour is the hallmark of the way experts respond to situations. The article seeks to investigate if the prerequisites for development of experience-based intuition are fulfilled inside the frames of military operations. The possible implications and consequences of utilizing such a capability are also emphasized. The article's empirical materials are qualitative and build mainly upon extracted information from interviews and informal conversations with Norwegian soldiers and officers serving in Afghanistan under ISAF's Regional Command North in 2007 and 2008.

The medical concept of prognosis is analysed into its basic constituents: patient data, medical intervention, outcome, utilities and probabilities; and sources of utility and probability values are discussed. Prognosis cannot be divorced from contemplated medical action, nor from action to be taken by the patient in response to prognostication. Regrettably, the usual decision-theoretic approach ignores this latter aspect. Elicitation of utilities, decision contemplation and prognostic counselling interweave, diagnostics playing a subsidiary role in decision-oriented clinical practice. At times the doctor has (...) grounds for withholding information. As this is known to the patient, prognostic counselling becomes a conflict-prone and rationality-thwarting activity. The meaning of standard phrases such as prognosis of a disease, the prognosis of this patient, the prognosis is unknown, is examined. (shrink)
Can we sensibly attribute some of the happenings in our world to the agency of some of the things around us? We do this all the time, but there are conceptual challenges purporting to show that attributable agency, and specifically one of its most important subspecies, human free agency, is incoherent. We address these challenges in a novel way: rather than merely rebutting specific arguments, we discuss a concrete model that we claim positively illustrates attributable agency in an indeterministic setting. (...) The model, recently introduced by one of the authors in the context of artificial intelligence, shows that an agent with a sufficiently complex memory organization can employ indeterministic happenings in a meaningful way. We claim that these considerations successfully counter arguments against the coherence of libertarian free will. (shrink)
The essays in this volume offer a thorough discussion of the relationship between addiction and rationality. This book-length treatment of the subject includes contributions from philosophers, psychiatrists, neurobiologists, sociologists and economists. Contrary to the widespread view that addicts are subject to overpowering and compulsive urges, the authors in this volume demonstrate that addicts are capable of making choices and responding to incentives. At the same time they disagree with Gary Becker's argument that addiction is the result of rational choice. The (...) volume offers an exposition of the neurophysiology of addiction, a critical examination of the Becker theory of rational addiction, an argument for a 'visceral theory of addiction', a discussion of compulsive gambling as a form of addiction, several discussions of George Ainslie's theory of hyperbolic discounting, analyses of social causes and policy implications, and an investigation of the problem of relapse.
