Traditional scholarship has generally neglected the philosophy of nature in Greek Neoplatonism. In the last few decades, however, this attitude has changed radically. Natural philosophy has increasingly been regarded as a crucial aspect of late antique thought. Furthermore, several studies have outlined the impressive historical legacy of Neoplatonic physics. Building on this new interest, the ten papers published here concentrate on Neoplatonic philosophy of nature from Plotinus to Simplicius, and on its main conceptual features and its relation to the previous philosophical and scientific traditions. The papers were presented at a conference sponsored by the European Science Foundation in Castelvecchio Pascoli in June 2006. This volume makes an important contribution to the understanding of Greek Neoplatonism and its historical significance.
