The term “vagueness” describes a property of natural concepts, which normally have fuzzy boundaries, admit borderline cases, and are susceptible to Zeno's sorites paradox. We will discuss the psychology of vagueness, especially experiments investigating the judgment of borderline cases and contradictions. In the theoretical part, we will propose a probabilistic model that describes the quantitative characteristics of the experimental finding and extends Alxatib's and Pelletier's () theoretical analysis. The model is based on a Hopfield network for predicting truth values. Powerful (...) as this classical perspective is, we show that it falls short of providing an adequate coverage of the relevant empirical results. In the final part, we will argue that a substantial modification of the analysis put forward by Alxatib and Pelletier and its probabilistic pendant is needed. The proposed modification replaces the standard notion of probabilities by quantum probabilities. The crucial phenomenon of borderline contradictions can be explained then as a quantum interference phenomenon. (shrink)

We consider several puzzles of bounded rationality. These include the Allais- and Ellsberg paradox, the disjunction effect, and related puzzles. We argue that the present account of quantum cognition—taking quantum probabilities rather than classical probabilities—can give a more systematic description of these puzzles than the alternate treatments in the traditional frameworks of bounded rationality. Unfortunately, the quantum probabilistic treatment does not always provide a deeper understanding and a true explanation of these puzzles. One reason is that quantum approaches introduce additional (...) parameters which possibly can be fitted to empirical data but which do not necessarily explain them. Hence, the phenomenological research has to be augmented by responding to deeper foundational issues. In this article, we make the general distinction between foundational and phenomenological research programs, explaining the foundational issue of quantum cognition from the perspective of operational realism. This framework is motivated by assuming partial Boolean algebras. They are combined into a uniform system via a mechanism preventing the simultaneous realization of perspectives. Gleason’s theorem then automatically leads to a distinction between probabilities that are defined by pure states and probabilities arising from the statistical mixture of pure states. This formal distinction relates to the conceptual distinction between risk and ignorance. Another outcome identifies quantum aspects in dynamic macro-systems using the framework of symbolic dynamics. Finally, we discuss several ideas that are useful for justifying complementarity in cognitive systems. (shrink)

Taking the lead from orthodox quantum theory, I will introduce a handy generalization of the Boolean approach to propositions and questions: the orthoalgebraic framework. I will demonstrate that this formalism relates to a formal theory of questions (or ‘observables’ in the physicist’s jargon). This theory allows formulating attitude questions, which normally are non-commuting, i.e., the ordering of the questions affects the answer behavior of attitude questions. Further, it allows the expression of conditional questions such as “If Mary reads the book, (...) will she recommend it to Peter?”, and thus gives the framework the semantic power of raising issues and being informative at the same time. In the case of commuting observables, there are close similarities between the orthoalgebraic approach to questions and the Jäger/Hulstijn approach to question semantics. However, there are also differences between the two approaches even in case of commuting observables. The main difference is that the Jäger/Hulstijn approach relates to a partition theory of questions whereas the orthoalgebraic approach relates to a ‘decorated’ partition theory (i.e. the elements of the partition are decorated by certain semantic values). Surprisingly, the orthoalgebraic approach is able to overcome most of the difficulties of the Jäger/Hulstijn approach. Furthermore, the general approach is suitable to describe the different types of (non-commutative) attitude questions as investigated in modern survey research. Concluding, I will suggest that an active dialogue between the traditional model-theoretic approaches to semantics and the orthoalgebraic paradigm is mandatory. (shrink)

The idea of complementarity is one of the key concepts of quantum mechanics. Yet, the idea was originally developed in William James’ psychology of consciousness. Recently, it was re-applied to the humanities and forms one of the pillars of modern quantum cognition. I will explain two different concepts of complementarity: Niels Bohr’s ontic conception and Werner Heisenberg’s epistemic conception. Furthermore, I will give an independent motivation of the epistemic conception based on the so-called operational interpretation of quantum theory, which has (...) powerfully been applied in the domain of quantum cognition. Finally, I will give examples illustrating the potency of complementarity in the domains of bounded rationality and survey research. Concerning the broad topic of consciousness, I will focus on the psychological aspects of awareness. This closes the circle spanning complementarity, quantum cognition, the operational interpretation, and consciousness. (shrink)

There is a gap between two different modes of computation: the symbolic mode and the subsymbolic (neuron-like) mode. The aim of this paper is to overcome this gap by viewing symbolism as a high-level description of the properties of (a class of) neural networks. Combining methods of algebraic semantics and non-monotonic logic, the possibility of integrating both modes of viewing cognition is demonstrated. The main results are (a) that certain activities of connectionist networks can be interpreted as non-monotonic inferences, and (...) (b) that there is a strict correspondence between the coding of knowledge in Hopfield networks and the knowledge representation in weight-annotated Poole systems. These results show the usefulness of non-monotonic logic as a descriptive and analytic tool for analyzing emerging properties of connectionist networks. Assuming an exponential development of the weight function, the present account relates to optimality theory – a general framework that aims to integrate insights from symbolism and connectionism. The paper concludes with some speculations about extending the present ideas. (shrink)

Based on the tenets of the so-called ‘radical pragmatics’ school (see, for instance, Cole, 1981), this book takes a particular view with regard to the relationship between content and linguistically encoded meaning. The traditional view embodied in the work of Montague and Kaplan (e.g., Kaplan, 1979; Montague, 1970) sees content being fully determined by linguistic meaning relative to a contextual index. In contrast, the radical view takes it that, although linguistic meaning is clearly important to content, it does not determine (...) it, as pragmatic principles also play a role. The central issue of this book is how to give a principled account of the determination of content. Seeing linguistic meanings as underdetermining the content (proposition) expressed, there must be a pragmatic mechanism of completion which can be best represented as an optimization procedure. It is demonstrated that the general framework of Optimality Theory (OT) makes it possible to formulate the desired explanatory principles. The first section of this general introduction outlines the basic framework of OT as applied to phonology, syntax and morphology. The second section takes a historical perspective and shows that the idea of optimization was present in the pragmatic enterprise right from the beginning. Further, it explains the main advantages of the general framework of OT when applied to the field of pragmatics, and it puts the whole idea into concrete terms by demonstrating how Horn’s (1984) theory of conversational implicature can be implemented within a bidirectional optimality theory. In section 3, we rise several basic questions underlying the whole volume and discuss them from a theoretical and empirical perspective. This part 1 gives a overview of the different topics treated in the book, and it explains in which respects the single contributions aim to satisfy our cooperative goal: to give a new impulse to the tradition of radical pragmatics. Section 4, finally, outlines basic open question of future research.. (shrink)

This contribution focuses on three aspects of Nietzsche’s art of living that have become relevant today especially in the United States (but not only here): first, regarding some facets of the economic-political conditions of any contemporary art of living; second, the widespread adoption of Nietzsche’s notion of self-overcoming and artistic self-design in entrepreneurship and individual’s lives; and third, how his notion of ‘incorporation’ has been further developed in current approaches to habit design. Eventually I will show via the example of (...) Anthony Robbins that some notions of Nietzsche’s art of living have become most popular outside of academia, namely in the commercial industries of what has been called ‘self-growth’ or ‘self-development.’.

English summary: The wide-ranging work of Ernst Fraenkel lead to the foundation of postwar political science. In his role as "American in Berlin," Fraenkel helped shape the foundation of modern comparative government theory. Fraenkel's impressive, and in retrospect exemplary, biography, from being a Jewish labor lawyer in the Third Reich to an emigrant to the United States, allowed for him to be described as a commanding figure of the young field of political science of the Adenauer era. Reinhard Dorn (...) illuminates Fraenkel's integrative state and constitutional understanding in two parts. In the first section, he presents foundations and individual components of constitutional-sociological thought, whereby he focuses particular attention on sociological and policy-sociological aspects. The second section documents the performance range of Fraenkel's constitution sociology by comparing Anglo-American and continental European constitutional thinking with its respective constitutional reality, all based on his own interdisciplinary analysis. German text. German description: Die Beschaftigung mit dem breit gefacherten Werk von Ernst Fraenkel fuehrt zu den Grundlagen der Nachkriegs-Politikwissenschaft. In seiner Rolle als Amerikaner in Berlin hat Fraenkel das Fundament der modernen vergleichenden Regierungslehre mitgestaltet. Dabei hat Fraenkels beeindruckende und im Rueckblick exemplarisch wirkende Biographie vom juedischen Arbeitsrechtler und Rechtsanwalt im Dritten Reich ueber den Emigranten in die USA zur Portalfigur der jungen Politikwissenschaft der Adenauer-Ara seine Verfassungsvergleiche erst ermoglicht.In zwei Teilen beleuchtet Reinhard Dorn Fraenkels integratives Staats- und Verfassungsverstandnis: Im ersten Abschnitt stellt er Grundlagen und einzelne Bestandteile seines verfassungssoziologischen Denkens dar, wobei er insbesondere auf soziologische und politiksoziologische Aspekte eingeht. Der zweite Abschnitt dokumentiert die Leistungsbreite von Fraenkels Verfassungssoziologie, indem - ausgehend von dessen eigenen interdisziplinaren Analysen - angloamerikanisches und kontinentaleuropaisches Verfassungsdenken der jeweiligen Verfassungsrealitat gegenuebergestellt wird.

Ten leading scholars provide exacting research results and a reliable and accessible introduction to the new field of optimality theoretic pragmatics. The book includes a general introduction that overviews the foundations of this new research paradigm. The book is intended to satisfy the needs of students and professional researchers interested in pragmatics and optimality theory, and will be of particular interest to those exploring the interfaces of formal pragmatics with grammar, semantics, philosophy of language, information theory and cognitive psychology.

Measurement instruments assessing multiple emotions during epistemic activities are largely lacking. We describe the construction and validation of the Epistemically-Related Emotion Scales, which measure surprise, curiosity, enjoyment, confusion, anxiety, frustration, and boredom occurring during epistemic cognitive activities. The instrument was tested in a multinational study of emotions during learning from conflicting texts. The findings document the reliability, internal validity, and external validity of the instrument. A seven-factor model best fit the data, suggesting that epistemically-related emotions should be conceptualised in terms (...) of discrete emotion categories, and the scales showed metric invariance across the North American and German samples. Furthermore, emotion scores changed over time as a function of conflicting task information and related significantly to perceived task value and use of cognitive and metacognitive learning strategies.

Auf der Arbeitstagung der Deutschen Gesellschaft fur Soziologie im Oktober 1961 hielten Karl R. Popper und Theodor W. Adorno Referate zur -Logik der Sozialwissenschaften-. Dies leitete den -Positivismusstreit- in der deutschen Soziologie ein, an dem sich prominent vor allem Jurgen Habermas auf Seiten der Kritischen Theorie der Frankfurter Schule und Hans Albert auf Seiten des Kritischen Rationalismus beteiligten. Der daraus entstandene Sammelband, der 1969 kurz vor dem Tod Adornos erschien, wurde im deutschen Sprachraum viel gelesen und diskutiert. Das -Adorno-Jahr- 2003 (...) und das -Popper-Jahr- 2004 gaben Anlass, sich mit den Fragen erneut auseinander zu setzen, die der Positivismusstreit aufgeworfen hat, und sie aus heutiger Sicht neu zu beleuchten. Dies wurde in den Referaten eines Symposiums der Karl Popper Foundation Klagenfurt unternommen. Dieser Sammelband beinhaltet die uberarbeiteten Referate dieses Symposiums. In ihnen werden die methodologische, die politische und die soziologische Dimension der damaligen Auseinandersetzungen mit heute dominierenden Themen und Positionen konfrontiert, was bisher in der einschlagigen wissenschaftlichen Diskussion nicht erfolgt ist.".

Sustainable development (SD) – that is, “Development that meets the needs of current generations without compromising the ability of future generations to meet their needs and aspirations” – can be pursued in many different ways. Stakeholder relations management (SRM) is one such way, through which corporations are confronted with economic, social, and environmental stakeholder claims. This paper lays the groundwork for an empirical analysis of the question of how far SD can be achieved through SRM. It describes the so-called SD–SRM (...) perspective as a distinctive research approach and shows how it relates to the wider body of stakeholder theory. Next, the concept of SD is operationalized for the microeconomic level with reference to important documents. Based on the ensuing SD framework, it is shown how SD and SRM relate to each other, and how the two concepts relate to other popular concepts such as Corporate Sustainability and Corporate Social Responsibility. The paper concludes that the significance of societal guiding models such as SD and of management approaches like CSR is strongly dependent on their footing in society. (shrink)

Fokus eines Kriegseinsatzes und Fluchtpunkt des Preußischen Staatsrats Schmitt und seiner Lebens-, Zeit-, Rechts- und Ideengeschichte. Korrumpiert und verstoßen, widerstrebend und vereinnahmt ging das "Chamäleon" Carl Schmitt im Dritten Reich seinen eigenen Weg. Die europäische Zeit- und Rechtsgeschichte spiegelt sich exemplarisch im Werden und Wirken des "Kronjuristen des Dritten Reiches", und heute sind die Ideen dieses Staatsrechtsvordenkers und Großraumvisionärs wieder brennend aktuell.

Reinhard Lauth (1919-2007) ist einer der bedeutendsten systematischen Philosophen des 20. Jahrhunderts. In der 1979 erschienenen "Theorie des philosophischen Arguments" fasste er in einer streng formalisierten Sprache die Grundlagen systematischen Philosophierens zusammen. In seinen letzten Lebensjahren hat er seinen transzendentalphilosophischen Ansatz weiter entwickelt, was in dem hier erstmals veröffentlichten zweiten Teil des Buchs ihren Niederschlag gefunden hat. Abgerundet wird das Ganze durch einige unveröffentlichte Aufsätze.

Even if formally precise, the economic concept of rationality has different empirical implications depending on how it is used in theory building. If it is used as a tool of microfoundation in multi-level analysis it can be applied universally, but does not imply a specific model of human behavior. As a means of constructing microtheories proper it is, on the other hand, translated into a definite model of man but can be applied only to specific situations. This model, known as (...) homo oeconomicus or economic man, should not be taken as an assertion about human nature but rather as a shorthand description of the behavior enforced and stabilized by social situations of a certain type.

This paper embeds the core part of Discourse Representation Theory in the classical theory of types plus a few simple axioms that allow the theory to express key facts about variables and assignments on the object level of the logic. It is shown how the embedding can be used to combine core analyses of natural language phenomena in Discourse Representation Theory with analyses that can be obtained in Montague Semantics.

Was Anselm zu einem leuchtenden Vorbild für die Theologie heute werden lässt, ist nicht seine Gelehrsamkeit, sondern das Wagnis, auf die Anfragen seiner Zeit durch mutige und eigenständige Synthesen des christlichen Denkens zu antworten. Die hier vorliegende Interpretation gestaltet sich als Versuch, die zuletzt etwas eingefahren wirkende Zugangsweise zum Werk Anselms auf einen neuen Boden zu stellen. Die Komplementarität von Teleologie und Eschatologie, bzw. die Begründung der ersteren in der letzteren bietet dafür den begrifflichen Rahmen, von welchem her sich neue (...) Einblicke in das Denken des Doctor magnificus ergeben. (shrink)

The legal intellectualism of the inter-war period (1918-1938) is often discussed under the heading of the 'conservative revolution'. Martin Heidegger was with his tradition criticism and his figurehead from the 'other beginning' in the 'step back' a main representative of this movement. The present book regards him primarily as a revolutionary, Nietzscheaner and utopian of Ubermenschen. It compares him to Ernst Junger and Carl Schmitt, discusses productive appropriations by Manfred Riedel and Friedrich Kittler, and portrays Thomas Mann as a positive (...) alternative and liberal variant against Heidegger." --Translated from back cover.

Die Dokumentation ist eine zentrale Quelle zur Geschichte der deutsch-judischen Emigrationsphilosophie. ARthur Liebert (1878-1946) war bis 1933 in Berlin der zentrale Organisator der Kant-Gesellschaft und Kant-Studien; Emil Utitz (1883-1956) profilierte als Ordinarius in Halle die philosophische Asthetik und Charakterologie; Liebert emigrierte 1933 nach Belgrad, 1939 nach England und kehrte 1946 nach Berlin zuruck; Utitz wechselte nach Prag, uberlebte das KZ Theresienstadt und blieb dann nach 1945 in Prag. BEide begrundeten nach 1933 philosophische Gesellschaften, die eng miteinander kooperierten und in der (...) Sicherung des Nachlasses von Edmund Husserl sowie der Herausgabe der Emigrationsfachzeitschrift Philosophia bis 1939 wichtige Aufgaben fanden. Das Buch rekonstruiert ihr Emigrationsschicksal, dokumentiert es durch die erhaltene Korrespondenz zwischen Utitz und Liebert sowie weitere sehr gewichtige Korrespondenzen und macht das Spatwerk der Autoren mit weithin unbekannten Texten zuganglich. Es erganzt die 2015 bei K&N erschienene Edition Ethik nach Theresienstadt. SPate Texte des Prager Philosophen Emil Utitz (1883-1956) historisch-biographisch. (shrink)
