Hilbert's axiomatization program of physical theories met an interesting challenge when it confronted the rise of quantum mechanics in the mid-twenties. The novelty of the mathematical apparatus of the then newly born theory was to be matched only by its substantial lack of any definite physical interpretation. The early attempts at axiomatization, which are described here, reflect all the difficulty of the task faced by Jordan, Hilbert, von Neumann and others. The role of von Neumann is examined in considerable detail (...) as he can be viewed here as the most outstanding of Hilbert's heirs. Von Neumann, especially in his work devoted to the proof of the impossibility of hidden variables, not only continued Hilbert's program but pushed it to its very limits, blending axiomatic rigor and interpretative commitment.

The essential role of classical mechanics in the “old quantum theory” is well known. With the rise of a genuine quantum formalism, classical analogies remained a powerful heuristic tool. However, classical insights soon proved problematic, and in some cases, even counterproductive. The case of the implementation of quantum canonical transformations provides a distinguished case study for the historian studying the circumstances which led to the transformation theory of London, Dirac and Jordan. -/- The attempts to use canonical transformations in strict (...) analogy to classical practice met serious difficulties as soon as one tried to accommodate the action-angle scheme. At some point, the very consistency of quantization went addressed because of the unclear quantum equivalence of classically equivalent Hamiltonians. -/- The early attempts, often beset with ill-defined problems, are illustrative of the lack of understanding of the underlying mathematical scheme. The latter had to be properly appraised before the problem of the meaning of changing variables in quantum theory could be solved. This is why the latter proved instrumental in the discovery of transformation theory. -/- Some of the problems which arose then are still highly instructive from the foundational point of view, and worth to be rediscovered, beyond their historical interest.

BackgroundIn Sweden, individuals with visual field loss have their driving license withdrawn. The literature clearly indicates that individuals with VFL are unsafe drivers on a group level. However, many drivers with VFL can be safe on an individual level. The literature also suggests that self-perception, beliefs, and insights of one’s own capabilities are related to driving performance. This study had three aims: To investigate self-perceived driving capability ratings for individuals with VFL; to compare these ratings between groups with different medical (...) conditions associated with VFL ; and to relate the self-perception ratings to actual driving performance in an advanced driving simulator.MethodsParticipants comprised 723 individuals whose driver’s license had been withdrawn because of VFL and 92 normally sighted elderly individuals. All participants completed a background survey, rated difficulties with different traffic situations, rated their strengths and weaknesses as drivers, and rated aspects that were important for causing traffic accidents. Of the VFL group participants, 264 also completed a simulator-based driving test that they knew could lead to renewal of their driving license. VFL participants and normally sighted was at the same age when they completed the simulator driving test.ResultsOverall, individuals with VFL rated their capabilities as high on all instruments and scales used, even higher than the elderly normally sighted control group. The only VFL etiology group that rated lower than other groups was the diabetes group. Safety orientation and internal control orientation values were best at discriminating between VFL participants in terms of self-perception of driving performance. Participants categorized as “high” in terms of safety skills and internal control were more modest in their ratings. Finally, participants who passed the simulated driving test did not differ from those who failed, in any of the self-perception measures.ConclusionSelf-perception ratings among individuals with VFL were higher than those of normally sighted elderly individuals. Self-assessed skills did not predict driving performance. Groups with different VFL etiologies rated similarly. Self-ratings of driving abilities cannot be used to assess actual driving performance. Actual driving tests are necessary to discriminate between safe and unsafe drivers with VFL. (shrink)

In the late 19th century, T. G. Masaryk presented his national programme. This vision of modern Czech society rested on the ideals of humanity, thus infusing the national ethos with a universal dimension. The significance of T. G. Masaryk's thought is investigated by current Czech thinkers in this volume.

Articles on Indian philosophy; a Marxist's viewpoint.

Článek analyzuje argument Pascalovy sázky a některé klíčové námitky proti ní – kritiku Antonyho Duffa, Alana Hájka a tradiční námitku mnoha Bohů. Pascalův argument je reformulován tak, aby těmto námitkám co nejlépe odolal. Analýza ukazuje, že revidovaná podoba sázky zůstává otevřeným problémem teorie rozhodování.The article analyzes some important reasons pro and contra Pascal`s wager argument. Many gods objection and objections by Antony Duff and Alan Hájek are discussed. A reformulation of Pascal`s wager is offered in order to make the case (...) for Pascal`s conclusion stronger. It is shown that some form of wager could still represent a serious problem for rational decision theory. (shrink)

The concept of a socially extended mind suggests that our cognitive processes are extended not simply by the various tools and technologies we use, but by other minds in our intersubjective interactions and, more systematically, by institutions that, like tools and technologies, enable and sometimes constitute our cognitive processes. In this article we explore the potential of this concept to facilitate the development of a critical neuroscience. We explicate the concept of cognitive institution and suggest that science itself is a (...) good example. Science, through various practices and rules, shapes our cognitive activity so as to constitute a certain type of knowledge, packaged with relevant skills and techniques. To develop this example, we focus on neuroscience, its cultural impact, and the various institutional entanglements that complicate its influence on reframing conceptions of self and subjectivity, and on defining what questions count as important and what kind of answers will be valued.

Jan Westerhoff unfolds the story of one of the richest episodes in the history of Indian thought, the development of Buddhist philosophy during the first millennium CE. He aims to offer the reader a systematic grasp of key Buddhist concepts such as non-self, suffering, reincarnation, karma, and nirvana.

The Anthropocene concept arose within the Earth System science community, albeit explicitly as a geological time term. Its current analysis by the stratigraphical community, as a potential formal addition to the Geological Time Scale, necessitates comparison of the methodologies and patterns of enquiry of these two communities. One means of comparison is to consider some of the most widely used results of the ESS, the ‘planetary boundaries’ concept of Rockström and colleagues, and the ‘Great Acceleration’ graphs of Steffen and colleagues, (...) in terms of their stratigraphical expression. This expression varies from virtually non-existent to pronounced and many-faceted, while in some cases stratigraphical proxies may help constrain anthropogenic process. The Anthropocene concepts of the ESS and stratigraphy emerge as complementary, and effective stratigraphic definition should facilitate wider transdisciplinary communication. (shrink)

Kaum ein anderer Denker hat die jüdische Moderne in einem so hohen Maße beeinflusst wie der Philosoph Baruch Spinoza. Als eine intellektuelle Grenzfigur, die nach ihrer Verbannung aus der jüdischen Gemeinde Amsterdams im Jahre 1656 in die christlich-abendländische Geisteswelt eintrat, inspirierte er jene Aufklärer der Haskala, die ein gutes Jahrhundert später nach einem eigenen jüdischen Weg in die europäische Moderne suchten. Diese Denker trafen dabei auf eine nichtjüdische Gelehrtenwelt, in der sich mit dem Namen des niederländischen Philosophen ebenso idealisierende Erwartungen (...) wie irrationale Ängste gegenüber dem in Spinoza identifizierten intellektuellen Idealtypus des Jüdischen verbanden. Somit ist die Geschichte der jüdischen Rezeption Spinozas seit dem Zeitalter der europäischen Aufklärung stets ein Indikator dafür, welchen Stand das wechselhafte Verhältnis zwischen jüdischer und nichtjüdischer Welt gerade erreicht hatte. Im Nachvollzug der Verlaufsformen der jüdischen Spinoza-Rezeption vom 17. bis ins 20. Jahrhundert zeigt die vorliegende Studie, wie sich jüdisches Selbstbild und Fremdzuschreibung immer wieder wechselseitig bedingt haben. (shrink)

This paper develops axiomatic foundations for a probabilistic-interventionist theory of causal strength. Transferring methods from Bayesian confirmation theory, I proceed in three steps: I develop a framework for defining and comparing measures of causal strength; I argue that no single measure can satisfy all natural constraints; I prove two representation theorems for popular measures of causal strength: Pearl's causal effect measure and Eells' difference measure. In other words, I demonstrate these two measures can be derived from a set of plausible (...) adequacy conditions. The paper concludes by sketching future research avenues. (shrink)

Terrorism is a global phenomenon that constantly challenges human survival. Based on the social structure, human beings adopt different strategies to overcome its negative consequences on their mind and behavior. Coping strategies and those processes essential for adjustment and survival illustrate how individuals perceive, consider, deal with, and realize a stressful situation in the era of terrorism. The study focuses on exploring coping strategies and avoidance of terrorism impacts. This research study was qualitatively designed to explore the coping strategies adaptation (...) and their influence on the former FATA individuals during the wave of terrorism in the region. The study was undertaken in five districts of erstwhile FATA, including Dara Adam Khel, Orakzai Agency, Khyber Agency, and North and South Waziristan agency. A sample size of twenty-five (25) participants was purposively selected and interviewed, ten (10) focused group discussions (FGDs) were done from each district, and the other 50 participants were chosen for ten (10) FGDs. The collected data were analyzed via the thematic analysis technique. The findings revealed that coping strategies included four different phases: the welcome, resistance, acceptance, surrender, and flee phases for overcoming threats of terrorism. Furthermore, it was also found that fear of terrorism had strongly influenced the individuals’ physical, socio-economic, psychological, emotional stress and fear, education, and social integration. The study recommended that social integration and solidarity among the people, as well as their cooperation with the government, can eliminate the threat of terrorism. (shrink)

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)

The arguments presented in this discussion point to some problems in the theory of communicative action considered as a starting point for a sociological theory with both normative and explanatory aspirations. It is argued that Habermas's notion of consensus is not sufficiently developed to constitute a foundation of the ethics of public debates; that both social action and communicative action are grounded in social actors' references to the same three worlds, which makes the coordination of actions by means of understanding (...) achieved in speech possible; that the criteria of rationality underlying use of language in the communicative action are ultimately those that are made explicit and consciously worked out in science; and that, finally, it is Parsons' solution to the Hobbesian problem and his concept of social action that provide a possible foundation for universalistic ethics.

Meetings differ from ordinary conversation in that they have an agenda that specifies in advance the topics to be addressed during the meeting. However, the introduction of these topics needs to be locally accomplished and recognized by the participants as agenda items. This article presents some characteristic practices used for introducing agenda-based topics. It shows that they rely on the known-in-advance status of the items, and are presented by the chair as unilateral announcements. They exploit and invoke the written agenda (...) in several ways. The announcements are often short phrasal constructions, just citing the written title of the agenda point. Furthermore, a gaze down at the written document is used as a public display that the introduction is related to the agenda. In contrast to this practice of introducing agenda items, topics not specified by the agenda are introduced by suggestions and questions that present the introduction as contingent on acceptance by the co-participants. The analysis sheds light on the ways in which institutional talk-in-interaction is permeated by the formulations and logic of written documents. (shrink)

The paper presents the sources and the development of the medieval doctrine of transcendentals. In Aertsen's opinion transcendental philosophy of the Middle Ages differs considerably from the ontological doctrine of the Ancients as well as from the modern theory referring to the sphere of cognition. The beginnings of the medieval doctrine of the transcendentals were inspired mostly by considerations concerning primary conceptions of human mind included in Avicenna's "Metaphysica". Furthermore, they were connected with the Aristotelian idea of science, the Boethian (...) axiomatic method of "common conceptions of the soul", and theologians' interest in the horizon of human intellectual knowledge. Beside the Aristotelian-Avicennian reduction to the most universal predicate Albert the Great acknowledge another reduction (originating from the Christian-Neoplatonic tradition): reduction to the first cause. In his opinion, these two resolutions are complementary to each other. In the philosophy of Thomas Aquinas, transcendentals are most fundamental insofar as they are the foundations of theoretical and practical science. The principle of contradiction – considered as the beginning of theoretical science – rests on the understanding of "being", and the first precept of natural law is founded on "the good". The development of the doctrine of the transcendentals in 13th century aloows to call the period "the second beginning of metaphysics" – since it changes the understanding of the proper subject of First Philosophy. In Albert the Great, for example, matephysics ceases to be the science of the divine, and becomes the science concerning what is first and the most fundamental – "being-as-being". In St. Bonaventure's philosophy, the doctrine of the transcendentals undergoes a theologizing transformation: that, which is first in the cognitive order is, at the same time, first ontologically. For Bonaventure, the latter "first" is God. (shrink)

This paper examines the implicit foundations of several theoretical propositions characteristic of the Marxist tradition in sociology. It argues that these propositions derive from self-contradictory critical premises which are paradoxes of Action Theory. Implicit in these premises is an ideal picture of social reality quite different from the one analytically described by Parsons. I suggest that Action Theory can provide conceptual tools needed to address some specific issues characteristic of the Marxist perspective and, moreover, offers a solution to some epistemological (...) problems raised by the authors who endorse the postmodern position in social sciences.
