ZusammenfassungNach einer historischen Übersicht über die Entwicklung der naturwissenschaftlichen Disziplinen in den vergangenen Jahrhunderten wird auseinandergesetzt, dass wir seit der Quantentheorie einige frühere Theorien, wie etwa die Newton'sche Mechanik, als abge‐schlossene Theorien bezeichnen. Der Sinn dieser Begriffsbildung wird besprochen, ebenso die Bedingungen, unter denen eine Theorie als abgeschlossen bezeichnet werden kann.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 267-268 [Access article in PDF] Myles Burnyeat. A Map of "Metaphysics" Zeta. Pittsburgh, PA: Mathesis Publications, 2001. Pp. x + 176. Paper, $25.00. Burnyeat's map is an ambitious attempt to establish two claims about Zeta: that Aristotle employs an unusual, non-linear form of argument in Zeta, and that the discussion in Zeta is on two levels, one abstract and "logical" and (...) another specific and "metaphysical." In addition to looking at Zeta, chapter by chapter, Burnyeat examines the other works that provide the context for Zeta—the Organon for the logical level of explanation and the rest of the Metaphysics for the metaphysical level. Burnyeat argues that Aristotle's metaphysical project culminates in the theology of'Lambda, for which the metaphysics of Zeta has prepared us. The goal is to "map" or sketch the evidence for these claims rather than provide definitive arguments for them.A brief introductory chapter presents the main themes of the book. This is followed by an even briefer chapter that sets out the four routes (or independent sections of Zeta), viz. Z 3; Z 4-6, 10-11 with Z 7-9, 12; Z 13-6; and Z 17 with H 1. On all four routes, a logical discussion moves to a metaphysical discussion of form and matter.The third chapter on "signposts" is the lengthiest of all and takes the reader through the chapters of Zeta in order. It is also the most map-like of the chapters, as it requires that the reader have a copy of the Metaphysics ready to hand. Burnyeat follows other commentators in treating Zeta 7-9 and Zeta 12 as later insertions; he does, however, argue that the former and probably the latter were added by Aristotle. Chapters 7-9 are integral to the argument of Zeta, as they provide a diachronic view of artifacts and substantial beings (37). [End Page 267] Rejecting the prominence assigned Z 13 by several recent commentators, Burnyeat reads Z 13 in context with chapters 14-6. "The task of Z 13-6 is to show how the idea that substantial being is a universal such as human leads eventually, after suitable refinements and restrictions, to the conclusion that substantial being is form" (54). Wrapping up the discussion of Zeta, Burnyeat concludes that the goal of Zeta's two-level approach has been to show how logical concepts should be used to search for form.This leads directly to a chapter on the Organon. Burnyeat argues that none of the treatises making up the Organon are metaphysical; all employ an abstract (logical) mode of analysis. Even if written at different times, these treatises belong together because they are all methodological. Since form and matter belong to the metaphysical level, in the Analytics Aristotle "follows a deliberate policy of excluding form and matter" (97).In the final chapter, Burnyeat returns to the Metaphysics and considers Zeta in the context of the other books. Three "chunks," viz. books ABGE, ZHQ, and MN are briefly surveyed. The topics of Zeta are then considered in relation to Lambda. Several chapters, viz. D1 and Z1; D3 and Z 7-9, are found to have the same concerns. Burnyeat concludes with a fanciful muqo~ (story) about a dying Aristotle hastily writing a culminating metaphysical treatise.Burnyeat gives us a map—a map to prompt questions; he does not attempt to delve into many of the interpretative puzzles that have exercised other interpreters of Zeta. Thus, this book stands as a helpful counterbalance to a certain kind of scholarship on Zeta. The two interpretative claims, however, that are at the heart of Burnyeat's enterprise stand in need of further justification. One of these, the non-linearity of Zeta, seems to be too weak to support substantive claims. Burnyeat defines non-linearity as holding when "it is not the case that the successive chapters build continuously upon the results of their predecessors" (4). He then cites a few examples of linearity, e.g., Physics II. Yet the vast majority of Aristotelian... (shrink)

‘My Africa Reads’ is a memoir that looks back at my reading history. The ‘Preamble’ identifies authors who influenced my worldview during my secondary and tertiary education in the UK and who remained my companions during the first decade of my return to Nigeria. From this immersion in Eurocentric literature, the memoir progresses to my encounter with postcolonial African literature in the collective setting of the Africa Book Group, which I joined in 2002 and led from 2014 to 2018. The (...) memoir looks at authors and literature that the international women of ABG have engaged with, and at meetings at which guest experts spoke on aspects of African studies and affairs. It highlights the power of ABG—a shared reading experience—to advance that part of my cultural liberation facilitated by good postcolonial literature and open, unconstrained discussions with other women.

Die vorliegende Arbeit befasst sich mit dem Denken der englischen Psychoanalytikerin und Malerin Marion Milner (1900–1998) und speziell mit dem Themenkreis von Kreativität und Kunst. Nachdem Milner dem Umstand nachgegangen war, dass ihr die Fähigkeit zum Malen abging, wurde ihr klar, dass der kreative künstlerische Prozess, verstanden als das Erschaffen neuer Symbole, die der neugeschaffenen Realität eine persönliche und subjektive Bedeutung beilegen, in Augenblicken eines anfänglichen »Wahnsinns« (der Illusion von Einheit, von prälogischer Fusion von Subjekt und Objekt) vor sich geht (...) und eine Wechselseitigkeit von innerer und äußerer Realität ermöglicht. In diesem Prozess kommt der ästhetischen Erfahrung des schaffenden Künstlers, wie sie zeigt, eine Schlüsselrolle zu. (shrink)

To justify certain steps of the computation developed in his Sand-Reckoner, Archimedes cites the following inequalities relative to the sides of right triangles: if of two right-angled triangles, the sides about the right angle are equal , while the other sides are unequal, the greater angle of those toward [sc. next to] the unequal sides has to the lesser a greater ratio than the greater line of those subtending the right angle to the lesser, but a lesser than the greater (...) line of those about the right angle to the lesser. That is, with reference to the two right triangles ABG, DEZ , where AG equals DZ and the angle at B is greater than that at E, ZE:GB < angle B:angle E < DE:AB. (shrink)
