Frank E. Zachos offers a comprehensive review of one of today's most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts (...) found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name ("species") is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.

We generalize Frécon’s construction of the inevitable radical to groups in stable and even simple theories.

An infinite field with only countably many pure types is algebraically closed.

We define the notion of generic for an arbitrary subgroup H of a stable group, and show that H has a definable hull with the same generic properties. We then apply this to the theory of stable fields.

This article addresses the extent and ways in which gender inequality in the newspaper coverage of arts and culture has changed in France, Germany, the Netherlands, and the United States, 1955-2005. Through a quantitative content analysis, we mapped all articles that appeared in two elite newspapers in each country in four sample years 1955, 1975, 1995, and 2005. First, despite increasing women’s employment in arts and culture and a quantitative feminization of journalism, elite newspaper coverage of women in arts and (...) culture has hardly changed, making up about 20-25 percent consistently over the last 50 years. Second, our results show surprisingly few cross-national differences in the amount of the newspaper coverage devoted to women in arts and culture. Third, although women are underrepresented in the coverage of all artistic genres, there is some evidence of horizontal sex segregation—particularly in architecture and modern dance and fashion —as well as vertical sex segregation—in that attention to women has increased in “highbrow” genres that have declined in status. Finally, as the status of an actor type increases from laymen to artistic directors, the proportion of women decreases in newspaper attention to arts and culture. (shrink)

Johann Georg Sulzer gehorte zu den pragenden Gestalten der europaischen Aufklarung in den 1750er und 1760er Jahren, sowohl in der Philosophie als auch in einer Reihe von Einzelwissenschaften - wie der Mathematik und der Padagogik - sowie im Kontext literarischer und asthetischer Diskurse. Federfuhrend nahm er an den wichtigen Debatten, Kontroversen und Forschungsentwicklungen teil, die etwa in Berlin, in Leipzig oder in Paris die Aufklarung beschaftigte. Der vorliegende Band versammelt Studien von Philosophen, Literaturwissenschaftlern und Wissenschaftshistorikern zu allen Werkbereichen Sulzers, insbesondere (...) zur lange Zeit vernachlassigten Erkenntnistheorie und Psychologie. Zugleich wird seine bislang weitgehend unbekannte praktische Philosophie diskutiert. Daruber hinaus werden auch Sulzers Sprach- und Kunsttheorie sowie seine Enzyklopadistik analysiert. MIT BEITRAGEN VON: Elisabeth Decultot, Werner Euler, Frank Grunert, Jutta Heinz, Marion Heinz, Dieter Huning, Heiner Klemme, Hans-Peter Nowitzki, Udo Roth, Gideon Stiening, Udo Thiel, Achim Vesper und Falk Wunderlich.".

The present study seeks to lay out the most basic elements of the ontology of classical Aš‘arite theology. In several cases this requires a careful examination of the traditional and the formal lexicography of certain key expressions. The topics primarily treated are: how they understood “Being/ existence” and “being/existent” and essential natures; the systematic exploitation of the equivocities of certain expressions within a general context in which other than words there are no universals proves to be elegant as well as (...) insightful; the basic categories of primary entities: independant beings and nonindependant beings, created and uncreated, the equivocity of “being/existent” as predicated of contingent entities on the one hand and of God and His attributes on the other, and certain problems that arise because of the rigid application of the system's underlying analytic principles. Nous essayons ici de presenter les éléments fondamentaux de l'ontologie de l'aš‘arisme classique. Pour quelques expressions, il a fallu examiner la lexicographie et ordinaire et technique pour bien comprendre leur emploi et leur signification. Les sujets examinés sont: le sens de “Etre/existence” et de “être/existant” et le concept de réalité essentielle; l'emploi nuancé des équivocités de quelques expressions dans un contexte où les seuls universaux sont des mots, emploi qui se révèle philosophiquement élégant; les catégories fondamentales des êtres: êtres indépendants et êtres non-indépendants, soit créés soit incréés, l'équivocité de “être/existant” dit des êtres contingents d'une part, de Dieu et ses attributs d'autre part, et enfin quelques difficultiés qui résultent de l'application rigide des principes analytiques du système.

Plato: The Timaeus There is nothing easy about the Timaeus. Its length, limited dramatic discourse, and arid subject-matter make for a dense and menacing work. But make no mistake, it is a menacing work of great subtly and depth. Cosmology has traditionally received the bulk of scholarly attention. No less important, however, are the dialogue’s … Continue reading Plato: The Timaeus →.
