Originally published in 2005. There has been much discussion in scholarly literature of the applicability of the concept of 'science' as understood in contemporary English to ancient Greek thought, and of the influence of philosophy and the individual sciences on each other in antiquity. This book focuses on how the ancients themselves saw the issue of the relation between philosophy and the individual sciences. Contributions, from a distinguished international panel of scholars, cover the whole of antiquity from the beginnings of both philosophy and science to the later Roman Empire.
