From Plato's Timaeus onwards, the world or cosmos has been conceived of as a living, rational organism. Most notably in German Idealism, philosophers still talked of a 'Weltseele' (Schelling) or 'Weltgeist' (Hegel). This volume is the first collection of essays on the origin of the notion of the world soul (anima mundi) in Antiquity and beyond. It contains 14 original contributions by specialists in the field of ancient philosophy, the Platonic tradition and the history of theology. The topics range from the 'obscure' Presocratic Heraclitus, to Plato and his ancient readers in Middle and Neoplatonism (including the Stoics), to the reception of the idea of a world soul in the history of natural science. A general introduction highlights the fundamental steps in the development of the Platonic notion throughout late Antiquity and early Christian philosophy. Accessible to Classicists, historians of philosophy, theologians and invaluable to specialists in ancient philosophy, the book provides an overview of the fascinating discussions surrounding a conception that had a long-lasting effect on the history of Western thought.

Ancient and Medieval Philosophy, Series 1, No. 39This book examines the important but largely neglected issue of the intricate mutual influences between Platonism and Stoicism in the Hellenistic period, the Imperial Age, and after. Although this interrelationship is often termed "eclecticism," the authors of Platonic Stoicism reveal that the situation is much more complicated. Far from being eclectics, most Stoics and Platonists consciously appropriated material and integrated it into their own philosophical system. The dialogue between Platonists and Stoics testifies to active debate and controversy on central topics such as psychology, epistemology, physics, and ethics.

Forms and Concepts is the first comprehensive study of the central role of concepts and concept acquisition in the Platonic tradition. It sets up a stimulating dialogue between Plato s innatist approach and Aristotle s much more empirical response. The primary aim is to analyze and assess the strategies with which Platonists responded to Aristotle s (and Alexander of Aphrodisias ) rival theory. The monograph culminates in a careful reconstruction of the elaborate attempt undertaken by the Neoplatonist Proclus (6th century AD) to devise a systematic Platonic theory of concept acquisition."

Historically speaking, the majority of efforts in the study of ancient Greek physics have traditionally been devoted either to the analysis of the surviving evidence concerning Presocratic philosophers or to the systematic examination of the Platonic and the Aristotelian oeuvre. The aim of this volume is to discuss the notion of space by focusing on the most representative exponents of the Hellenistic schools and to explore the role played by spatial concepts in both coeval and later authors who, without specifically thematising these concepts, made use of them in a theoretically original way. To this purpose, renowned scholars investigate the philosophical and historical significance of the different conceptions of space endorsed by various thinkers ranging from the end of the Classical period to the middle Imperial age. Thus, the volume brings to light the problematical character of the ancient reflection on this topic.
