The problem of the Rota Aristotelis deals with the unrolling of two tightly connected concentric circles with different radii. It is to be found in Chapter 24 of the text Mechanica of the Aristotelian corpus (today generally no longer attributed to Aristotle) and has bothered many authors until the modern age. All these scholars agree that the solution given there is not satisfactory. We conclude that Chapter 24 is close to Aristotle, at least, both from a philological and philosophical point (...) of view. The solution of the problem given in the ancient text can very well be transferred into a modern physical phenomenological explanation. (shrink)

The ancients were interested in the questions of what love really is, why it exists, and how it is experienced. This book presents the best examples, from Homer to Apuleius, interpreted and analyzed by the author. Through an examination of these selections from Greek and Latin literature, some main themes are revealed: success in love with the help of a god; the pursuit of happiness, unity, and completeness; love and beauty; love as an illness, wound, or suffering; betrayal in love, (...) adultery, murder, and death; love as the creating force of the world; the existence of friendship; the basis of parental love; the meaning of love for oneself; the basis and the results of the gods' love for humans. Also included is a comparison of ancient ideas of love with those in later literature and our own ideas about love today. (shrink)

This specimen of a forthcoming book on the void in ancient natural philosophy by using an example illustrates the problems that confront the scholar. The term εὐτονία, used by Chrysippus, occurs in the Pneumatics of Hero of Alexandria in connection with empty pores. Has he borrowed the notion from Stoic philosophy, or was Strato of Lampsacus, older than Chrysippus, the first to use it? In all probability it was Ctesibius who independently of Stoic philosophy applied the term to account for (...) the kinetic qualities of the material used for his inventions, and Philo Byzantius took over the notion from him. Hero may have derived it from Ctesibius either directly or via Philo. (shrink)

Die Abhandlung weist auf, dass bestimmte Elemente des modernen Bildes der Griechen in Deutschland Konstruktionen im Sinn von Gegenbildentwürfen zur Gegenwart sind. Diese wurden in Zeiten herrschenden Krisenbewusstseins entwickelt, am Ende des 18. Jahrhunderts sowie vom Ende des 19. und im ersten Drittel des 20. Jahrhunderts, und sie sind bis heute virulent. Die Opposition von Gegenwart und griechischer Antike ist von der expliziten oder impliziten Gegenüberstellung der Metaphern 'Kreis und Gerade' bestimmt und betrifft die Literatur, die Zeit- und die Geschichtsvorstellung (...) der Griechen. Kreis und Gerade stehen für Vollkommenheit - Unvollkommenheit, Geschlossenheit - Offenheit, Form - Formlosigkeit, Mittelpunkt - Fehlen eines Mittelpunkts, Endlichkeit - Unendlichkeit, Statik - Dynamik, Sein - Werden. Diese Nachweise exponiert ein Blick auf die Verlusterfahrungen der Neuzeit (Kugelgestalt des Kosmos, Kreisform der Bahnen der Himmelskörper)."--Back cover. (shrink)
