The most important analytical tool in non-cooperative game theory is the concept of a Nash equilibrium, which is a collection of possibly mixed strategies, one for each player, with the property that each player's strategy is a best reply to the strategies of the other players. If we do not go into normative game theory, which concerns itself with the recommendation of strategies, and focus instead entirely on the positive theory of prediction, two alternative interpretations of the Nash equilibrium concept (...) are predominantly available.In the more traditional one, a Nash equilibrium is a prediction of actual play. A game may not have a Nash equilibrium in pure strategies, and a mixed strategy equilibrium may be difficult to incorporate into this interpretation if it involves the idea of actual randomization over equally good pure strategies. In another interpretation originating from Harsanyi, see also Rubinstein, and Aumann and Brandenburger, a Nash equilibrium is a ‘consistent’ collection of probabilistic expectations, conjectures, on the players. It is consistent in the sense that for each player each pure strategy, which has positive probability according to the conjecture about that player, is indeed a best reply to the conjectures about others.

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.

Filosofi og pædagogik er gamle fæller, og der er et overlap mellem filosofiens historie og pædagogikkens historiske litteratur. Store tænkere som Platon, Aristoteles, Augustin, Descartes, Locke, Rousseau, Kant, Hegel, Schleiermacher, Herbart og Dewey hører hjemme begge steder. I den pædagogiske filosofi kan almene teoretiske og praktisk filosofiske spørgsmål udforskes systematisk og historisk. Gennem diskussioner af sådanne spørgsmål kan man forholde sig mere nysgerrigt, bevidst, begrundet og kritisk til pædagogisk praksis såvel som til pædagogisk teori, empiri og undervisningsteknologi. -/- Fællesskabet er (...) ikke uproblematisk. Pædagogik er ikke filosofi, og pædagogisk filosofi ikke kun pædagogik. Både didaktik og almen pædagogik kan komme i konflikt med pædagogisk filosofi. Hvordan kan almene pædagogiske spørgsmål overhovedet belyses filosofisk, og hvad betyder de for filosofien selv? En pædagogisk filosofisk tilgang forandrer kanon i både pædagogik og filosofi. Udvalget af nøgletekster ændres. Emner, der er værd at diskutere, forskydes. Nye forskningsspørgsmål og prioriteringer viser sig. Et pædagogisk perspektiv på filosofiens udvikling vil fremhæve dens bidrag til at forstå ’den pædagogiske problem- og fænomenverden’, ligesom et filosofisk perspektiv på pædagogikken vil flytte – eller rettere udvide – fokus med hensyn til dens idéhistorie såvel som dens aktuelle teoretiske praksis. Som i al anden filosofi kan man i den pædagogiske filosofi diskutere teoretiske og praktiske, såvel som poetiske og æstetiske spørgsmål; men det er typisk med en særlig vinkel, nemlig den pædagogiske. Man kan således diskutere erkendelse, viden og sandhed, ligeså vel som man kan undersøge ret, retfærdighed og skønhed. Ofte vil det være med en særlig tvist. Den pædagogiske filosofi kan vise sig som særegen både ved sin særlige position og ved at relatere sig til det pædagogiske som genstandsfelt. Hvad denne position og dette genstandsfelt egentlig er, er der dog ingen enighed om. Det kan ikke engang siges at være udelukkende pædagogisk defineret, og derfor må den pædagogiske filosofi forholde sig åbent til begge dele. Studier i pædagogisk filosofi indbyder til denne drøftelse. (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.

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)

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)

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)

Between the two World Wars, Jørgen Jørgensen was a central figure in Danish philosophy and internationally recognized, as his teacher Harald Høffding had been before World War 1. When in the late 1920s Jørgensen established contact with the movement that would later be called logical positivism, he found a group of philosophers of his own age who advocated empiricism, the tools of formal logic and the Unity of Science, and who shared his anti-metaphysical approach to philosophy. He became one of (...) the movement’s organizers and wrote its history, but he was only for a short period influenced by especially Rudolf Carnap’s philosophy of logic. Although Jørgensen was never an uncritical member of the movement, he is often considered as a central representative of logical positivism in Scandinavia. (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 define the paraconsistent supra-logic Pσ by a type-shift from the booleans o of propositional logic Po to the supra-booleans σ of the propositional type logic P obtained as the propositional fragment of the transfinite type theory Q defined by Peter Andrews as a classical foundation of mathematics. The supra-logic is in a sense a propositional logic only, but since there is an infinite number of supra-booleans and arithmetical operations are available for this and other types, virtually anything can be (...) specified. The supra-logic is a generalization of Lukasiewicz's three-valued logic, with the intermediate value duplicated many times and ordered such that none of the copies of this value imply other ones, but it differs from Lukasiewicz's many-valued logics as well as from logics based on bilattices. There are several automated theorem provers for classical higher order logic and it should be possible to modify these to our needs. (shrink)

Berkeley’s criticism of Locke’s distinction between primary and secondary qualities is a challenge to epistemologists. Do we experience a mind-independent reality, even though we do it with the help of senses bound to give us subjective experiences? Berkeley – or a straw man by that name – played an important part as sparring partner for an influential development of Danish theoretical philosophy in the second half of the 20th century. The protagonists here are Peter Zinkernagel and David Favrholdt. Zinkernagel held (...) an extraordinary appointment as research fellow at the University of Copenhagen. Favrholdt was the founding father of the Philosophical Institute at Odense University. This essay focuses on the constructive moments in Zinkernagel’s alternative to immaterialism, being based on a distinction between perception and action, and on Favrholdt’s development of a reconstruction of the distinction between primary and secondary qualities.

The Danish critic Georg Brandes visited Warsaw in 1885 and 1886, with the pretext of lecturing—in French—on modern literature, making thereby the Polish cause for freedom his own. It was his endeavor not to take sides in the smoldering strife between radical and catholic circles, freedom from the brutal Russian regime being the chief common issue. During his second visit he lectured on Polish literature, though only knowing it through translations. This demonstration of solidarity was received with enthusiasm.In his book (...) Impressions from Poland—Danish 1888, in English, German and Polish 1898—he gives a vivid description of the Polish passion for freedom, not hiding more negative sides of the national character as he found them, such as improvidence and bohemianism. The book was understood as an act of solidarity, and during a visit to Krakow in 1898 he was hailed as the spokesman of freedom and one of the few West-European supporters of the Polish cause.When, by November 1914, Brandes learned about Polish religious pogroms he did not hesitate to condemn them in two articles born by indignation. The articles, immediately published in many languages, aroused much attention worldwide, at the same time costing him most of his Polish popularity. (shrink)

The purpose of this paper is to explore the reception of George Berkeley in a particular corner of 20th-century Danish psychology and philosophy. In contrast to philosophers, such as Peter Zinkernagel and David Favrholdt, Danish experimental psychologists, including Edgar Rubin and Edgar Tranekjær Rasmussen, made highly appreciative reference to the methodology and experimental observations of Berkeley and David Hume. This paper focuses on these psychologists’ interest in Berkeley’s ideas. I will first present Rubin’s path from a mosaic-like understanding of psychological (...) phenomena to a holistic view, detailing what he termed adspective psychology and its method. I then turn to Rubin’s embrace of certain experimental observations made by Berkeley and, in particular, by Hume concerning the minima visibilia. The second part of the paper deals with Tranekjær Rasmussen’s interpretation of Berkeley’s work, and in particular of his immaterialism, his notion of God, and his critique of abstract ideas.
