Die „Grundlage der gesamten Wissenschaftslehre“ bleibt für den, der Fichte im philosophiegeschichtlichen Zusammenhang sehen will, der wichtigste Text; dies gilt auch dann noch, wenn die Akademie-Ausgabe abgeschlossen sein wird. Der Jenaer Fichte hat nicht nur auf seine Zeitgenossen am stärksten gewirkt, er war auch seinerseits damals noch am offensten für Einflüsse. Der vorliegende Kommentar – der erste, der den gesamten deutschen Text behandelt – bietet keine Paraphrase, keine Übersetzung in eine zeitgemäßere Sprache, keine „Darstellung“, die Fichtes Disposition durch eine eigene (...) ersetzt und damit – gewollt oder ungewollt – in Konkurrenz zum Original tritt. Er will vielmehr den Leser auf seinem dornigen Pfad Satz für Satz begleiten und bei keiner Schwierigkeit im Stich lassen. Die konkrete Erforschung literarischer Bezüge und Abhängigkeiten zeigt, wie sehr der „Selbstdenker“ Fichte – unbeschadet seiner Eigenständigkeit – nicht nur in der Philosophie, sondern im ganzen Geistesleben der Epoche verwurzelt ist. Durch die ausgiebigen, mit sprachlichen Erläuterungen versehenen Zitate entlegener Quellen ist der Kommentar zugleich eine Art Lesebuch. (shrink)

This article focuses on the development of, and new theorising about, a strong democracy education intervention, the Just Community approach. Three questions frame the discussion: (1) Does democracy education change children and adolescents or do students in these programs change their schools, or is there a dynamic interaction over time? (2) How can democracy be ?learned?? How can the concept of democracy be most thoroughly learned and how can democratic problem?solving skills best be acquired? (3) How can we optimise the (...) chances that the knowledge and skills learned will motivate future active citizenship? The article begins with a brief history of the Just Community approach, a description of the original developmental model created by Lawrence Kohlberg and collaborators and some variation in more recent European Just Community programs. In a discussion of controversial and difficult issues democracy education may face, the second question takes centre stage and several structural aspects are offered that should be included in such efforts to maximise their effectiveness. In the remainder of the article new perspectives coming from Europe are introduced. Some additional pathways to the Just Community approach and their justifications, which have not played a significant role in the theory and practice of the ?traditional? model but can add to its strengths, are identified. Finally, the idea of ?trusting in advance? is introduced as critical for well?functioning educational democracies. (shrink)

In this commentary we describe findings in normal human subjects and in patients with visual hemineglect that support the importance of higher-level influences on saccade generation during visual exploration. As the duration of fixations increases with increases in the cognitive demand of the task, the timing of exploratory saccades is controlled more by centers of cognitive and perceptual processing at levels 4 and 5 than by reflex-like automatic processes at level 3. In line with this, unilateral frontal eye field lesions (...) impair systematic, intentional saccadic exploration of visual scenes, causing prolonged fixations and contralesional hemineglect, but leave visually triggered reflexive saccades largely intact.

An action-oriented perspective changes the role of an individual from a passive observer to an actively engaged agent interacting in a closed loop with the world as well as with others. Cognition exists to serve action within a landscape that contains both. This chapter surveys this landscape and addresses the status of the pragmatic turn. Its potential influence on science and the study of cognition are considered (including perception, social cognition, social interaction, sensorimotor entrainment, and language acquisition) and its impact (...) on how neuroscience is studied is also investigated (with the notion that brains do not passively build models, but instead support the guidance of action). A review of its implications in robotics and engineering includes a discussion of the application of enactive control principles to couple action and perception in robotics as well as the conceptualization of system design in a more holistic, less modular manner. Practical applications that can impact the human condition are reviewed (e.g., educational applications, treatment possibilities for developmental and psychopathological disorders, the development of neural prostheses). All of this foreshadows the potential societal implications of the pragmatic turn. The chapter concludes that an action-oriented approach emphasizes a continuum of interaction between technical aspects of cognitive systems and robotics, biology, psychology, the social sciences, and the humanities, where the individual is part of a grounded cultural system.

BackgroundFreezing of gait is a disabling burden for Parkinson’s disease patients with poor response to conventional therapies. Combined deep brain stimulation of the subthalamic nucleus and substantia nigra moved into focus as a potential therapeutic option to treat the parkinsonian gait disorder and refractory FoG. The mechanisms of action of DBS within the cortical-subcortical-basal ganglia network on gait, particularly at the cortical level, remain unclear.MethodsTwelve patients with idiopathic PD and chronically-implanted DBS electrodes were assessed on their regular dopaminergic medication in (...) a standardized stepping in place paradigm. Patients executed the task with DBS switched off, conventional STN DBS and combined STN+SN DBS and were compared to healthy matched controls. Simultaneous high-density EEG and kinematic measurements were recorded during resting-state, effective stepping, and freezing episodes.ResultsClinically, STN+SN DBS was superior to conventional STN DBS in improving temporal stepping variability of the more affected leg. During resting-state and effective stepping, the cortical activity of PD patients in STIM OFF was characterized by excessive over-synchronization in the theta, alpha, and high-beta band compared to healthy controls. Both active DBS settings similarly decreased resting-state alpha power and reduced pathologically enhanced high-beta activity during resting-state and effective stepping compared to STIM OFF. Freezing episodes during STN DBS and STN+SN DBS showed spectrally and spatially distinct cortical activity patterns when compared to effective stepping. During STN DBS, FoG was associated with an increase in cortical alpha and low-beta activity over central cortical areas, while with STN+SN DBS, an increase in high-beta was prominent over more frontal areas.ConclusionsSTN+SN DBS improved temporal aspects of parkinsonian gait impairment compared to conventional STN DBS and differentially affected cortical oscillatory patterns during regular locomotion and freezing suggesting a potential modulatory effect on dysfunctional cortical-subcortical communication in PD.

Nobel Laureate in physics Wolfgang Pauli studied philosophy and the history of ideas intensively, especially in his later years, to form an accurate ontology vis-à-vis quantum theory. Pauli's close contacts with the Swiss psychiatrist C.G. Jung gave him special qualifications for also understanding the basic problems of empirical knowledge. After Pauli's sudden death in 1958, this work was maintained mainly in his posthumously published correspondence, which so far extends only to 1939. Because Pauli's view differs essentially from the direction (...) physics research took after the deaths of the founding fathers of quantum theory, this article attempts to describe the main features in Pauli's revolutionary thought, which is based on nature's “epistemological lesson” as revealed by Pauli's atomic research. Pauli's conclusions have important implications for various issues in Western culture, not least with the limits of science and the relation of science to religion. (shrink)

Cognitive science is experiencing a pragmatic turn away from the traditional representation-centered framework toward a view that focuses on understanding cognition as "enactive." This enactive view holds that cognition does not produce models of the world but rather subserves action as it is grounded in sensorimotor skills. In this volume, experts from cognitive science, neuroscience, psychology, robotics, and philosophy of mind assess the foundations and implications of a novel action-oriented view of cognition. Their contributions and supporting experimental evidence show that (...) an enactive approach to cognitive science enables strong conceptual advances, and the chapters explore key concepts for this new model of cognition. The contributors discuss the implications of an enactive approach for cognitive development; action-oriented models of cognitive processing; action-oriented understandings of consciousness and experience; and the accompanying paradigm shifts in the fields of philosophy, brain science, robotics, and psychology.

The systems Kα of transfinite cumulative types up to α are extended to systems K∞α that include a natural infinitary inference rule, the so-called limit rule. For countable α a semantic completeness theorem for K∞α is proved by the method of reduction trees, and it is shown that every model of K∞α is equivalent to a cumulative hierarchy of sets. This is used to show that several axiomatic first-order set theories can be interpreted in K∞α, for suitable α.

This paper investigates whether managerial rhetoric in the Management Discussion and Analysis section of 10-K filings can help gauge the level of managerial opportunism in a firm. We find that the use of trust-related words is connected to inefficient investment decisions and poor operating performance. Furthermore, firms making more frequent use of trust-related words are subject to less monitoring by institutional investors or analysts. Their accounting also relies more heavily on discretionary accruals. These results are consistent with the notion that (...) managerial rhetoric to advertise trustworthiness points towards agency problems plaguing the firm. (shrink)

Der vorliegende Band enthalt sechs teilweise stark iiberarbeitete Aufsatze, die in der Zeit zwischen der Niederschrift des Buches Theorienstrnkturen und Theoriendynamik, Springer-Verlag 1973, im folgenden mit [Theoriendynamik] bezeichnet, und der Monographie The Strncturalist View of Theories. A Pos­ sible Analogue of the Bourbaki Programme in Physical Science, Springer-Ver­ lag 1979, im folgenden kurz [Strnkturalismus] genannt, entstanden sind. In diesen Abhandlungen werden jeweils gewisse Aspekte des strukturalistischen Theorienkonzeptes behandelt. Am starksten iiberarbeitet wurden die Auf­ satze II, IV, V und VI, die (...) urspriinglich in englischer Sprache erschienen waren. Vier der sechs Arbeiten, namlich I, III, IV und VI, bilden auBerdem erweiterte Fassungen von Vortragen. Obwohl das zweite Buch [Strnkturalismus] durch P. Feyerabends ausftihr­ liche Diskussion der strukturalistischen Auffassung im British Journal for the Philosophy of Science, Dezember 1977, angeregt worden ist, stellt es seinem Ansatz und Aufbau nach eher den Versuch einer systematischen Kurzdarstel­ lung des strukturalistischen Vorgehens nach seinem letzten Stande dar. Dem­ gegeniiber entstanden die hier verOffentlichten Artikel stets aus einem ganz be­ stimmten AnlaB. Diese Anlasse konnte man schematisch in drei Klassen unter­ teilen: Entweder ging es darum, eine anschauliche intuitive Ein/iihrnng zu lie­ fern ; oder die Aufgabe bestand darin, die Beziehung zu anderen philosophischen Positionen. wie z. B. derjenigen L. Wittgensteins, H. Putnams, K. Poppers oder T. S. Kuhns. zu analysieren ; oder es sollte zu den wichtigsten und bis dahin verOffentlichten Kritiken Stellung bezogen wer­ den.

BackgroundThe preferable position of Deep Brain Stimulation electrodes is proposed to be located in the dorsolateral subthalamic nucleus to improve general motor performance. The optimal DBS electrode localization for the post-operative improvement of balance and gait is unknown.MethodsIn this single-center, retrospective analyses, 66 Parkinson’s disease patients were assessed pre- and post-operatively by using MDS-UPDRS, freezing of gait score, Giladi’s gait and falls questionnaire and Berg balance scale. The clinical outcome was related to the DBS electrode coordinates in x, y, z (...) plane as revealed by image-based reconstruction. Binomial generalized linear mixed models with fixed-effect variables electrode asymmetry, parkinsonian subtype, medication, age class and clinical DBS induced changes were analyzed.ResultsSubthalamic nucleus-deep brain stimulation improved all motor, balance and FoG scores in MED OFF condition, however there were heterogeneous results in MED ON condition. DBS electrode reconstructed coordinates impacted the responsiveness of axial symptoms. FoG and balance responders showed slightly more medially located STN electrode coordinates and less medio-lateral asymmetry of the electrode reconstructed coordinates across hemispheres compared to non-responders.ConclusionDeep brain stimulation electrode reconstructed coordinates, particularly electrode asymmetry on the medio-lateral axis affected the post-operative responsiveness of balance and FoG symptoms in PD patients.

How should rational beliefs change over time? The standard Bayesian answer is: by conditionalization (a.k.a. Bayes’ Rule). But conditionalization is not an adequate rule for updating beliefs in “centred” propositions whose truth-value may itself change over time. In response, some have suggested that the objects of belief must be uncentred; others have suggested that beliefs in centred propositions are not subject to diachronic norms. Iargue that these views do not offer a satisfactory account of self-locating beliefs and their dynamics. A (...) third response is to replace conditionalization by a new norm that can deal with centred propositions. I critically survey anumber of new norms that have been proposed, and defend one particular approach. (shrink)

Background: The Parkinsonian [i.e., Parkinson's disease ] gait disorder represents a therapeutical challenge with residual symptoms despite the use of deep brain stimulation of the subthalamic nucleus and medical and rehabilitative strategies. The aim of this study was to assess the effect of different DBS modes as combined stimulation of the STN and substantia nigra and environmental rehabilitative factors as footwear on gait kinematics.Methods: This single-center, randomized, double-blind, crossover clinical trial assessed shod and unshod gait in patients with PD with (...) medication in different DBS conditions during different gait tasks and compared gait characteristics to healthy controls. Notably, 15 patients participated in the study, and 11 patients were analyzed after a dropout of four patients due to DBS-induced side effects.Results: Gait was modulated by both factors, namely, footwear and DBS mode, in patients with PD. Footwear impacted gait characteristics in patients with PD similarly to controls with longer step length, lower cadence, and shorter single-support time. Interestingly, DBS exerted specific effects depending on gait tasks with increased cognitive load. STN+SN DBS was the most efficient DBS mode compared to STIM OFF and STN DBS with intense effects as step length increment during dual task.Conclusion: The PD gait disorder is a multifactorial symptom, impacted by environmental factors as footwear and modulated by DBS. DBS effects on gait were specific depending on the gait task, with the most obvious effects with STN+SN DBS during gait with increased cognitive load. (shrink)

Most material below is ranked around the splittings of lattices of normal modal logics. These splittings are generated by nite subdirect irreducible modal algebras. The actual computation of the splittings is often a rather delicate task. Rened model structures are very useful to this purpose, as well as they are in many other respects. E.g. the analysis of various lattices of extensions, like ES5, ES4:3 etc becomes rather simple, if rened structures are used. But this point will not be touched (...) here. The variety T BA , which corresponds to S4, is congruence- distributive. Hence any every tabular extension L S4 has nite many extensions only. Around 1975 it has been proved by several authors, that also the converse is true: If L S4 has nitely many extensions only, then L is necessarely tabular. These and other results will be extended to much richer lattices. For simplicity we state the results explicitely only for the lattice N of modal logics with one modal operator. But most of them carry over literally to the lattice Nk of k-ramied normal modal logics . It is easy to construct examples of 2-ramied modal logics which are P OST-complete but not tabular. Whether this will be possible for normal modal logic seems to be an open problem. In view of results below it seems very unlikely that such examples exist. (shrink)

Die Reihe formaler Sprachen, die im Verständnis von M.J. Cresswell "sinnvoll" als Modelle für natüriiche Sprachen anzusehen sind und die dabei auch semantische Vagheiten zu erfassen gestatten, nämlich die dreiwertige Logik (U. Blau), die Superbewertung (B.C. van Fraassen, K. Fine, M. Pinkal, J. Ballweg) und die unscharfe Logik (L.A. Zadeh), legt nahe, daß bei der Sprachanalyse Zadehs "Prinzip der Inkompatibilität" gilt: Hohe Präzision ist inkompatibel mit hoher Komplexität. Je komplexer man das Vagheitsproblem angeht, desto verschwommener wird der benutzbare Geltungswert. Zudem (...) wird die Sprachanalyse auf Empirie verwiesen: Die Superbewertung erfordert eine Beschreibung von Kontexten, die unscharfe Logik eine sprachempirische Untersuchung aller Geltungswerte.

Starting with a definition of „group” and the discussion of the meaning of groups for the individual life, especially the experimental studies of Kurt Lewin, Ronald Lippitt and Raph K. White in 1937/38 on different group atmospheres under the influence of „democratic” vs. „autocratic” vs. „laissez faire” leading style are presented again, in order to give an example for the (...) meaning of atmosphere influences on personal development, creativity and aggression – all topics concerning actual school situations and the daily experience of pupils and teachers. The collection of writings concerning education for democracy and tolerance include some of Lewin’s writings on minority problems and Metzger’s fundamental thougts on political education as a special application of productive thinking in Wertheimer’s sense. Some possibilities of how to change prejudices and to develop tolerance in Lewin’s and Metzger’s sense are presented. As a conclusion, some ideas for actual school life and possibilities to make pupils tolerant and able to participate actively in a democratic society are developed. (shrink)

Es wird gezeigt, daß K. Poppers Falsifikationsprinzip konsequenterweise nicht nur auf die zur Diskussion stehende Hypothese anzuwenden ist, sondern ebenso auf die Hypothesen, die für die Falsifikation als gültig angesehen werden. Dadurch wird der Entscheidungs-Charakter von Falsifikationen relativiert, eine befriedigende Übereinstimmung mit dem tatsächlichen methodologischen Vorgehen in den exakten Wissenschaften erzielt und somit ein Haupteinwand gegen Poppers Logik der Forschung gegenstandslos.

Building on the writings of Wittgenstein on rule-following and deviance, Kristóf Nyíri advanced a theory of creativity as consisting in a fusion of conflicting rules or disciplines. Only such fusion can produce something that is both intrinsically new and yet capable of being apprehended by and passed on to a wider community. Creativity, on this view, involves not the breaking of rules, or the deliberate cultivation of deviant social habits, but rather the acceptance of enriched systems of rules, the adherence (...) to which presupposes simultaneous immersion in disciplines hitherto seen as being unrelated. The paper presents a demonstration of the fruitfulness of this theory by means of an account of some of the political, cultural and intellectual peculiarities of the Habsburg Monarchy. (shrink)

We prove that the continuous function${\rm{\hat \Omega }}:2^\omega \to $ that is defined via$X \mapsto \mathop \sum \limits_n 2^{ - K\left} $ for all $X \in {2^\omega }$ is differentiable exactly at the Martin-Löf random reals with the derivative having value 0; that it is nowhere monotonic; and that $\mathop \smallint \nolimits _0^1{\rm{\hat{\Omega }}}\left\,{\rm{d}}X$ is a left-c.e. $wtt$-complete real having effective Hausdorff dimension ${1 / 2}$.We further investigate the algorithmic properties of ${\rm{\hat{\Omega }}}$. For example, we show that the maximal (...) value of ${\rm{\hat{\Omega }}}$ must be random, the minimal value must be Turing complete, and that ${\rm{\hat{\Omega }}}\left \oplus X{ \ge _T}\emptyset \prime$ for every X. We also obtain some machine-dependent results, including that for every $\varepsilon > 0$, there is a universal machine V such that ${{\rm{\hat{\Omega }}}_V}$ maps every real X having effective Hausdorff dimension greater than ε to a real of effective Hausdorff dimension 0 with the property that $X{ \le _{tt}}{{\rm{\hat{\Omega }}}_V}\left$; and that there is a real X and a universal machine V such that ${{\rm{\Omega }}_V}\left$ is rational.

My aim in this paper is to present and evaluate one version of the deflationary attitude to truth, namely the Modest Account, propounded by Wolfgang Künne in his Conceptions of Truth (2003). I introduce the deflationary theories of truth in the first part of my paper and present briefly the views of a more familiar deflationist, Paul Horwich, as a "stepping-stone" to Künne's account. In the second part of the paper I give an overview of Künne's theory and in (...) the final part I present a dilemma that his account faces: either it is not modest after all or it is incomprehensible.
