Ein Kommentar, mit den Texten des Vorworts zu Grundgesetze der Arithmetik und der Logischen Untersuchungen I–IV. RoteReihe 30. Frankfurt: V. Klostermann, 2010. Pp. 840. Paper, €29.80.Frege’s thought has been a permanent point of interest among philosophers for several decades. In (...) the late sixties a few philosophers, such as Christian Thiel and Ignacio Angelelli, published studies on Frege’s logic, semantics, and metaphysics. In 1973 Michael Dummett’s work on Frege’s philosophy of language appeared, which held the stage for a long time. It presented Frege as a predecessor, even as a representative, of the analytic tradition. New approaches came up in the late 1970s and early 1980s, such as Hans Sluga’s work in 1980 and other studies, which paid special attention to Frege’s German background, where Kant played a significant role. Several scholars, including Michael Dummett, started to dig into Frege’s background. Positions varied; some studied Frege’s background in order to show that there is nothing that could help us understand his philosophical insights; others found the origins of his philosophical and logical ideas precisely in his background and philosophical environment, in such philosophers as Leibniz, Kant, Trendelenburg, and Lotze.After a few somewhat more quiet years, Frege scholarship expanded after 2000. A number of books have appeared that discuss Frege in the analytic context and also seek [End Page 507] to find more details about his philosophical sources. Wolfgang Künne’s work is a most welcome contribution to contemporary scholarship in the field. Lothar Kreiser’s Gottlob Frege: Leben—Werk—Zeit (2001) has already been available, and interpretations of Frege’s philosophy as well as editions and translations of his books contain short biographies. Still, because of its special composition, Künne’s work serves to fill a gap in the scholarship and significantly contributes to what is known about Frege’s logic and philosophy.The volume consists of three parts. First, there is an extensive biography (about 50 pages) of Frege that places Frege’s thought in its historical context and also contextualizes those of his articles that are included in the work. The main projects Frege pursued, most notably the project of logicism, receive proper attention in the first part of the volume. The four texts that are included in the volume are the Preface of the Grundgesetze der Arithmetik I (1893) and the three logical investigations that were published during Frege’s lifetime, namely “Der Gedanke” (1918), “Die Verneinung” (1919), and “Gedankengefüge” (1923), which were originally published in Beiträge zur Philosophie des deutschen Idealismus. Künne has also included a posthumously published text, “Logische Allgemeinheit,” in the volume, as that fragment, which was not written before 1923, was intended to be a fourth logical investigation. The five texts written by Frege that are included in the edition discuss topics that we would now call philosophical logic, such as meaning, reference, and truth, although they also study themes that we would include in ontology and the philosophy of mind. The title of the volume is thus sufficiently motivated.Frege’s texts take up about 100 pages of the volume, while the commentary is about 600 pages. The book also contains an appendix on Bolzano and Frege, where Künne pays attention to similarities between the two logicians and philosophers but also shows his skepticism about the thesis that Frege had read Bolzano. Apart from this position, Künne prefers to read Frege’s texts closely and inform his reader of historical and philological matters rather than take part in any heated debates concerning interpretations; his own positions become visible only indirectly, through the extensive footnotes. The work also contains a very useful bibliography and indexes of names and subjects.The book is extremely rich. If one, for example, wishes to know more about the views of Frege’s German contemporaries, about the standpoints that Russell or Wittgenstein had on Fregean topics, or about the arguments of Frege scholars, one can find...

The major theoretical framework relative to the perception of illusory figures is reviewed and discussed in the attempt to provide a unifying explanatory account for these phenomena.

Following the pioneering studies of the receptive field (RF), the concept gained further significance for visual perception by the discovery of input effects from beyond the classical RF. These studies demonstrated that neuronal responses could be modulated by stimuli outside their RFs, consistent with the perception of induced brightness, color, orientation, and motion. Lesion scotomata are similarly modulated perceptually from the surround by RFs that have migrated from the interior to the outer edge of the scotoma and in this way (...) provide filling-in of the void. Large RFs are advantageous to this task. In higher visual areas, such as the middle temporal and inferotemporal lobe, RFs increase in size and lose most of their retinotopic organization while encoding increasingly complex features. Whereas lowerlevel RFs mediate perceptual filling-in, contour integration, and figure–ground segregation, RFs at higher levels serve the perception of grouping by common fate, biological motion, and other biologically relevant stimuli, such as faces. Studies in alert monkeys while freely viewing natural scenes showed that classical and nonclassical RFs cooperate in forming representations of the visual world. Today, our understanding of the mechanisms underlying the RF is undergoing a quantum leap. What had started out as a hierarchical feedforward concept for simple stimuli, such as spots, lines, and bars, now refers to mechanisms involving ascending, descending, and lateral signal flow. By extension of the bottom-up paradigm, RFs are nowadays understood as adaptive processors, enabling the predictive coding of complex scenes. Top-down effects guiding attention and tuned to task-relevant information complement the bottom-up analysis. (shrink)

This major work covers almost all that has been learned about the acoustics of stringed instruments from Helmholtz's 19th-century theoretical elaborations to recent electroacoustic and holographic measurements.Many of the results presented here were uncovered by the author himself over a 20-year period of research on the physics of instruments in the violin family. Lothar Cremer is one of the world's most respected authorities on architectural acoustics and, not incidentally, an avid avocational violinist and violist.The book - which was published (...) in German in 1981 - first of all meets the rigorous technical standards of specialists in musical acoustics. But it also serves the needs and interests of two broader groups: makers and players of stringed instruments are expressly addressed, since the implications of the mathematical formulations are fully outlined and explained; and acousticians in general will find that the work represents a textbook illustration of the application of fundamental principles and up-to-date techniques to a specific problem.The first - and longest - of the book's three parts investigates the oscillatory responses of bowed strings. The natural nonlinearities that derive from considerations of string torsion and bending stiffness are deftly handled and concisely modeled.The second part deals with the body of the instrument. Special attention is given to the bridge, which transmits the oscillations of the strings to the wooden body and its air cavity. In this case, linear modeling proves serviceable for the most part - a simplification that would not be possible with lute - like instruments such as the guitar.The radiation of sound from the body into the listener's space, which is treated as an extension of the instrument itself, is the subject of the book's final part.Lothar Cremer is Professor Emeritus at the Technical University of Berlin, where he served as director of the Institute for Acoustical Engineering.

Gilt das Verbot der Tötung Unschuldiger absolut oder darf selbst diese fundamentale Moralnorm unter Ausnahmebedingungen verletzt werden? Wir leben in einer Welt voller Gefahren. Das Leben von Menschen wird bedroht durch verbrecherische Diktaturen, terroristische Anschläge, technische Havarien und Katastrophen verschiedener Art. Dürfen solche Gefahren notfalls auch dann bekämpft werden, wenn dabei Unschuldige getötet werden oder ihr Tod in Kauf genommen werden muss? Das Buch gibt eine moralphilosophische Antwort auf diese politisch, ethisch und rechtlich umstrittene Frage. Lothar Fritze analysiert das (...) Rechtsdogma der Nichtabwägungsfähigkeit menschlichen Lebens und fragt, wie sich das Verbot der Tötung Unschuldiger mit der verbreiteten moralischen Intuition vereinbaren lässt, wonach in Extremfällen durchaus einige wenige unschuldige Menschen geopfert werden dürfen, um sehr viele andere Unschuldige zu retten.

Alongside the 'critical theory' of the Frankfurt School, West Germany was also home to another influential Marxist current known as the Marburg School. In this volume, Marburg disciple Lothar Peter traces the school's history and situates it in the political discourse and developments of its time. The renowned political scientist Wolfgang Abendroth plays a large role, but unlike most histories of the Marburg School Peter also takes the sociologists Werner Hofmann and Heinz Maus into account as well as their (...) many students and successors. They were united by the conviction that teaching and scholarship must necessarily be tied to the practical goal of transforming society - an approach that met with considerable opposition in the harshly anti-Communist atmosphere of the period.

Die digitale Transformation erfasst die Medien der Literatur und Literaturkritik in unterschiedlicher Geschwindigkeit. Die Substituierung der gedruckten Zeitung, der Stammheimat der Literaturkritik, durch digitale Formate ist weit vorangeschritten. Auf dem Buchmarkt ist das gedruckte Hardcover nach wie vor ein relativ stabiles Element. Der Beitrag kommentiert diese Differenz in medienhistorischer Perspektive.
