The last decade has seen an enormous development in infinite-valued systems and in particular in such systems which have become known as mathematical fuzzy logics. The paper discusses the mathematical background for the interest in such systems of mathematical fuzzy logics, as well as the most important ones of them. It concentrates on the propositional cases, and mentions the first-order systems more superficially. The main ideas, however, become clear already in this restricted setting.

For classical sets one has with the cumulative hierarchy of sets, with axiomatizations like the system ZF, and with the category SET of all sets and mappings standard approaches toward global universes of all sets. We discuss here the corresponding situation for fuzzy set theory.Our emphasis will be on various approaches toward (more or less naively formed)universes of fuzzy sets as well as on axiomatizations, and on categories of fuzzy sets.

The choice of connectives for many valued propositional logics suitable for theoretical and applicational interests in most cases is an open problem up to now. We will not offer a general solution here, but support the point of view of some recent developments in fuzzy set theory that the triangular norms – t-norms for short – of Schweizer/Sklar [3] and the ϕ-operators of Pedrycz [2] represent quite general classes of connectives at least for many valued logics with truth value set (...) the real interval [0,1] . Special classes of t-norms and general properties of them have been discussed in some papers just recently, e.g. by Dombi [1], Weber [4], Yager [5] to mention only a few of them. (shrink)

Taking its cue from contemporary western debates on presence in the social sciences and the humanities, this volume focuses on "presence" both as everyday experience and as an experience of intense moments. It raises questions about diverse social configurations of presence as well as about the specific cultural repertoires which encode, articulate, and shape discourses of presence. The contributions take as a premise that phenomena of presence are connected to particular forms of knowledge. Especially tacit knowledge (pre)determines experiences of individual (...) and collective presence and becomes tangible in moments of presence or presentification. (shrink)

This book explores the impact of disintegrity on various aspects of governance, as the disregard of ecological conditions produce grave direct effects to human rights (to water or food) and, indirectly, also to human security in several ways. International legal regimes need to be reconsidered and perhaps re-interpreted, in order to correct these situations that affect the commons today. Some believe that our starting point should acknowledge the impact we already have on the natural world, and accept that we now (...) live in the "anthropocene". Others think that the present emphasis on sustainable development needs to be re-defined. Finally, many believe that reconnecting with moral principles both in professional life and in governance in general represents a necessary first step. (shrink)

Musik ist anders. Durch Sprechen und Schreiben ist sie nicht zu ersetzen. Dennoch erzeugt sie den Wunsch nach Verständigung: über Musik selbst und über Zusammenhänge, die sie zu dem werden lassen, was sie ist. Auch wenn sie sich medial stets autonom verwirklicht, so ist Musik nicht isoliert. Die klingende Kunst reagiert - auf andere Musik, aber auch auf soziale oder ästhetische Bedingungen ihrer Zeit, wenngleich mit eigenen Mitteln. Der Band versammelt 35 Beiträge zur Musik von der Renaissance bis zum Bebop (...) und Techno, die aus musik- und literaturwissenschaftlichen, theologischen, philosophischen, philologischen und analytischen Perspektiven an diesen Gedanken anschliessen.

Dispositional essentialism is a non-Humean view about the essences of certain fundamental or natural properties that looms large in recent metaphysics , not least because it promises to explain neatly the natural modalities such as laws of nature, counterfactuals, causation and chance. In the current paper, however, several considerations are presented that indicate a serious tension between its essentialist core thesis and natural “metaphysical” interpretations of its central explanatory claims.

Bücher zählen bis heute zu den wichtigsten kulturellen Errungenschaften der Menschheit. Ihre Erfindung war mit der Einführung des Buchdrucks ähnlich bedeutsam wie des Internets: Erstmals wurde eine massenweise Weitergabe von Informationen möglich. Bildung, Wissenschaft, Forschung, aber auch die Unterhaltung wurde auf neuartige, technisch wie inhaltlich revolutionäre Basis gestellt. Bücher verändern die Gesellschaft bei heute. Die technischen Möglichkeiten des Massen-Buchdrucks führten zu einem radikalen Zuwachs an Titeln im 18. Und 19 Jahrhundert. Dennoch waren die Rahmenbedingungen immer noch ganz andere als heute: (...) Wer damals ein Buch schrieb, verfasste oftmals ein Lebenswerk. Dies spiegelt sich in der hohen Qualität alter Bücher wider. Leider altern Bücher. Papier ist nicht für die Ewigkeit gemacht. Daher haben wir es uns zur Aufgabe gemacht, das zu Buch gebrachte Wissen der Menschheit zu konservieren und alte Bücher in möglichst hoher Qualität zu niedrigen Preisen verfügbar zu machen. (shrink)
