I review arguments demonstrating how the concept of “particle” numbers arises in the form of equidistant energy eigenvalues of coupled harmonic oscillators representing free fields. Their quantum numbers (numbers of nodes of the wave functions) can be interpreted as occupation numbers for objects with a formal mass (defined by the field equation) and spatial wave number (“momentum”) characterizing classical field modes. A superposition of different oscillator eigenstates, all consisting of n modes having one node, while all others have none, defines (...) a non-degenerate “n-particle wave function”. Other discrete properties and phenomena (such as particle positions and “events”) can be understood by means of the fast but continuous process of decoherence: the irreversible dislocalization of superpositions. Any wave-particle dualism thus becomes obsolete. The observation of individual outcomes of this decoherence process in measurements requires either a subsequent collapse of the wave function or a “branching observer” in accordance with the Schrödinger equation—both possibilities applying clearly after the decoherence process. Any probability interpretation of the wave function in terms of local elements of reality, such as particles or other classical concepts, would open a Pandora’s box of paradoxes, as is illustrated by various misnomers that have become popular in quantum theory.

As a result of the pressures of modernization and those of overcoming a national security crisis, moral education has been instituted as a regular course in the Korean school system.Moral education in Korea aims to reinforce desirable aspects of the Korean value system, such as: self-control, sincerity, freedom, acceptance of responsibility, development of traditional culture, commitment to national development, respect for humanity,contribution to world peace, anti-communism, etc.Adoption of moral education as a regular course of study in Korean schools has resulted (...) in a renewal of discussions regarding the matter. It is generally felt that moral education is a life-long process which should not be restricted to schools. Furthermore, an improvement in educational methods as well as evaluative techniques are necessary in order to improve the teaching of moral education in Korea. Moral education, as practised in Korea, should bring about the exploration of alternative methods leading to better methodology. (shrink)

It is demonstrated that neither the arguments leading to inconsistencies in the description of quantum-mechanical measurement nor those “explaining” the process of measurement by means of thermodynamical statistics are valid. Instead, it is argued that the probability interpretation is compatible with an objective interpretation of the wave function.

Theodor Adorno's famous aesthetic theory was not merely a theory of the aesthetic; it also made a wider claim about the aesthetic implications of all theory. At the same time we have to deal with aesthetic objects and events in which an aesthetic theory is inherent, which show themselves as art. From both sides--theory and aesthetics--a link can be made to the etymological meaning of theōria, which understands the theoretical as a seeing or perspective. Featuring lucid essays by major thinkers, (...) the book examines this link, focusing equally on the aesthetic implications of theory and the theoretical implications of aesthetic events. (shrink)

The program of a physical concept of information is outlined in the framework of quantum theory. A proposal is made for how to avoid the intuitive introduction of observables. The conventional and the Everett interpretations in principle may lead to different dynamical consequences. An ensemble description occurs without the introduction of an abstract concept of information.

Wer kennt GOTTLOB FREGE (1848-1925)? Nur wenige verbinden mit seinem Namen einen der groaten Logiker aller Zeiten, ohne dessen "Logik von Funktion und Argument" die heutige Computertechnik kaum denkbar ist. Frege fuhlte sich zeitlebens zu seiner Heimat im Norden Deutschlands hingezogen. In Wismar verbrachte er seine Kindheit und in Bad Kleinen, in unmittelbarer Nahe, seinen Lebensabend. Das im Jahre 2000 gegrundete Gottlob-Frege-Zentrum der Hochschule Wismar organisierte ihm zu Ehren im Mai 2013 in seiner Geburtsstadt eine internationale Konferenz, an der Forscher (...) aus der mathematischen Grundlagenforschung und der Analytischen Philosophie teilnahmen. Im Konferenzband erfahren Sie von bekannten Wissenschaftlern u.a., begin{itemize} item was Frege zur Entwicklung der Mathematik, Logik und Philosophie leistete, item welche wissenschaftlichen Auffassungen Frege vertrat und welche er scharf kritisierte, item mit welchen bekannten Wissenschaftlern Frege korrespondierte und wer sein Werk fortsetzte oder in Frage stellte, item was wir heute noch aus Freges Arbeiten lernen konnen.

This book provides a unique survey displaying the power of Riccati equations to describe reversible and irreversible processes in physics and, in particular, quantum physics. Quantum mechanics is supposedly linear, invariant under time-reversal, conserving energy and, in contrast to classical theories, essentially based on the use of complex quantities. However, on a macroscopic level, processes apparently obey nonlinear irreversible evolution equations and dissipate energy. The Riccati equation, a nonlinear equation that can be linearized, has the potential to link these two (...) worlds when applied to complex quantities. The nonlinearity can provide information about the phase-amplitude correlations of the complex quantities that cannot be obtained from the linearized form. As revealed in this wide ranging treatment, Riccati equations can also be found in many diverse fields of physics from Bose-Einstein-condensates to cosmology. The book will appeal to graduate students and theoretical physicists interested in a consistent mathematical description of physical laws. (shrink)

This chapter establishes the concept of a “symbolic system of representation“ to make clear how it is possible that humans use not only the language-based system of representation for cognitive contents but also a many layered non-linguistic system, a system which we probably share with other species. A symbolic system of representation denotes a general concept of a performance of which our language is only one single case, but which nevertheless is most easily explained through the case of language. A (...) system of representation should enable us to form and manipulate an idea of a state of affairs or of an event without having the appropriate intuition of it. We usually think that we do this only using linguistic expressions, but this is not the whole truth. Language is one system of representation, but we can in principle conceive of other systems of representation with the same performance. Husserl’s theory of meaning already reveals this possibility. A phenomenological analysis reveals that a non-linguistic system of representation is in fact still functioning in our own consciousness. We simultaneously use different means of representation, the most prominent of which are language, gestures, feelings and scenic images. It is especially fruitful to investigate the scenic mode of daydreaming as a central form of non-linguistic thinking. Through a close comparison of alternative systems of representation, the systematic difference of usual semantics in normal language systems based on convention and the more natural similarity semantics of some non-linguistic systems of representation is revealed.

Zu den Grenzfragen des Lebens. Bioethik als Feld intensiver Auseinandersetzung im fachwissenschaftlichen Diskurs und kontroverser Diskussionen in der breiten Öffentlichkeit. Das Handbuch erläutert die Grundlagen und gibt einen Überblick über Bereiche, in denen bioethische Fragen relevant sind, wie Menschenwürde, Leben, Tod und Krankheit. Daneben widmet es sich den speziellen bioethischen Problemen wie etwa Zulässigkeit von Sterbehilfe, Präimplantationsdiagnostik oder embryonaler Stammzellenforschung und zeigt die Schnittstellen der Bioethik zu anderen Disziplinen und gesellschaftlichen Bereichen auf (Bioethik in der Lehre, Biopolitik, Biorecht und Ethikkommissionen).

Für die 3. Auflage wurde der Band durchgesehen und die Literaturliste aktualisiert. Der Band gibt einen Überblick über die Probleme der Moralphilosophie und die Antworten der Ethik auf die Frage nach dem Wesen, den Funktionen und den Inhalten der Moral. Ein besonderer Akzent liegt auf der Unterscheidung der Ebenen, auf denen moralische und ethische Diskurse geführt werden. Geeignet ist die Einführung auch für Leser ohne besondere Vorkenntnisse.

Our starting point is the question ‘What is mass’, what in particular enables mass to constitute duration: so that mass can be regarded as moving as well as at rest (the kinematic principle of relativity). In a thought experiment, this question is attacked here not from the perspective of mass itself, but from that of a standing light wave. In this model, mass-analogous structures can be re- constructed that can be in relative motion to each other. The (empirically known) constancy (...) of the speed of light in every reference system is not as- sumed here. However, it can be shown that the speed of light is identical in all systems constituted by mass-analogous structures that move uniformly relative to each other and that the speed of light moreover is the limiting speed of mo- tions. This indepence of the motion of light from the system of reference, this character of absoluteness, and the relativity of mass motions thus prove to be contrary but inextricably linked moments of the kinematic principle of relativi- ty: an interesting perspective concerning a philosophy of relativity theory. - The mathematical relationships are explained in more detail in the appendix.

Einer der auffälligsten gesellschaftlichen Trends der letzten zwanzig Jahre ist die zunehmende Moralisierung von Bereichen des individuellen und gesellschaftlichen Lebens, die in früheren Zeiten eher der Logik der effektiven Interessenverfolgung vorbehalten waren. Die Forderung nach der Übernahme und Wahrnehmung moralischer Verantwortung hat Lebensbereiche erfasst, die lange Zeit weitgehend außerhalb der Moral standen: Wirtschaft, Umwelt, Ressourcennutzung.

There is a consensus that satire cannot be defined, but is best characterized by a cluster account. However, I argue that a cluster account does not acknowledge the artistically and politically significant distinction between real satire and some forms of frivolous topical comedy which are casually labeled ‘satire’ in international media contexts. To uphold this distinction, I introduce a weak proposal that satire is a genre which necessarily sets out to critique and entertain (with the qualification that these purposes necessarily (...) interact, although neither is wholly instrumental to the other). I further argue that this proposal also provides necessary and sufficient conditions for a definition of satire. (shrink)

Ausgangspunkt ist die Frage, was Masse ist, wodurch sie insbesondere befähigt ist, Dauer zu konstituieren und deshalb - im Sinn des kinematischen Relativitätdprinzips - ebenso als bewegt wie als ruhend betrachtet werden kann. In einem Gedankenexperiment wird diese Frage, in Umkehrung der Perspektive, hier nicht von der Masse selbst, sondern von einer stehenden Lichtwelle her angegangen. In diesem Modell lassen sich masse-analoge Strukturen rekonstruieren, die in relativer Bewegung sein können. Die (empirisch bekannte) Unabhängigkeit der Lichtgeschwindigkeit vom Bezugssystem ist dabei nicht (...) vorausgesetzt. Doch kann gezeigt werden, dass die Lichtgeschwindigkeit Grenzgeschwindigkeit solcher relativer Bewegungen ist, dass dies für alle durch masse-analoge Strukturen konstituierte, relativ zueinander gleichförmig bewegten Bezugssysteme gilt und dass die Lichtgeschwindigkeit selbst in allen diesen Systemen gleich ist. Die Absolutheit der Lichtgeschwindigkeit und die Relativität der Massebewegungen erweisen sich so als zwar differente, aber intrinsisch zusammengehörende Momente des kinematischen Relativitätsprinzips: ein Beitrag zu einer Philosophie der Relativitätstheorie. - Die mathematischen Zusammenhänge werden im Anhang ausführlicher dargelegt.

Evolution is frequently concentrated in bursts of rapid morphological change and speciation followed by long‐term stasis. We propose that this pattern of punctuated equilibria results from an evolutionary tug‐of‐war between host genomes and transposable elements (TEs) mediated through the epigenome. According to this hypothesis, epigenetic regulatory mechanisms (RNA interference, DNA methylation and histone modifications) maintain stasis by suppressing TE mobilization. However, physiological stress, induced by climate change or invasion of new habitats, disrupts epigenetic regulation and unleashes TEs. With their capacity (...) to drive non‐adaptive host evolution, mobilized TEs can restructure the genome and displace populations from adaptive peaks, thus providing an escape from stasis and generating genetic innovations required for rapid diversification. This “epi‐transposon hypothesis” can not only explain macroevolutionary tempo and mode, but may also resolve other long‐standing controversies, such as Wright's shifting balance theory, Mayr's peripheral isolates model, and McClintock's view of genome restructuring as an adaptive response to challenge.

Ethics in the 21st century is threatened by a split between practical philosophy as a full-blown academic discipline and applied ethics as pragmatic problem-solving inside the political process. The place of the professional philosopher sitting on medical and other ‘ethics committees’ as an ‘ethical expert’ is somewhere in between. But where exactly? How is his role defined? Is the expertise he brings to bear on practical decisions of a purely technical or of a substantially moral kind? These issues are discussed (...) both ‘from the outside’ and ‘from the inside’. First, some of the theoretical controversies surrounding ‘ethical expertise’ are discussed on the background of a rapidly growing literature in the field. These are then related to the realities of commission work as they confront the academic ethicist in practice. (shrink)

Die Geschichte des Diskurses um Mills Moralphilosophie verläuft in einer Kurve wechselnder Konjunkturen. Phasen des Interesses und der überwiegend positiven Würdigung wechseln sich ab mit Phasen des Desinteresses und überwiegender Ablehnung. Im viktorianischen England war Mill der bekannteste Intellektuelle seiner Epoche – ungeachtet der Tatsache, dass er zu vielen Themen alles andere als zu seiner Zeit populäre Auffassungen vertrat. Allerdings galt das Interesse seiner Zeitgenossen weniger seiner Moralphilosophie als vielmehr seiner ökonomischen Theorie und der in seinem System of Logic enthaltenen (...) Methodologie der induktiven Wissenschaften. Dagegen erregte der Kern seiner Moralphilosophie, die in seinem Essay Utilitarianism dargelegte Version eines nicht-Bentham’schenBentham, Jeremy Utilitarismus, weniger Aufsehen, als sich Mill erhofft hatte.

Dieter Flader explores how current social and cultural concerns are connected to the unconscious, and how this affects our responses to them. Flader focuses on the role of the ego, assessing how our feelings about these issues in adulthood grow from childhood fears and desires, and integrating the existing psychoanalytic theories of Winnicott, Lacan, Kohut and others with sociological and political theory. The interdisciplinary approach not only analyses current social issues but also generates new perspectives and solutions, and examines (...) examples including climate change, bullying and vegetarianism.

Die meisten Sozial- und Geisteswissenschaften kennzeichnen sich durch das Bemühen darum, die Welt mit klaren Kategorien zu erkennen. Diesem unterliegt die Vorstellung der linearen Grenze. Unter Rückgriff auf Befunde aus dem nordafrikanischen und europäischen Mittelmeerraum kontextualisiert der vorliegende Artikel mit ethnologischem Blick das Gedankenmodell der Linearität historisch, politisch und kulturell, indem er dieses mit Grenzen als Zonen des Überganges kontrastiert und nach dem epistemologischen Gewinn fragt, der sich daraus für die Disziplinen entfaltet.
