'An excellent collection that will help to transform the study of later ancient philosophy. With comprehensive mastery of the widely scattered evidence, Sharples has selected, translated and annotated the most important sources for Aristotle's school during this crucial period, thereby enabling a greatly improved understanding not just of Aristotle's own legacy, but also of later Platonism, Stoic philosophy and other intellectual developments in late antiquity. This sourcebook will be a vital resource for teaching and research for years to come.' Brad Inwood, University of Toronto

'During the four centuries 200 BC–AD 200 foundations for the invention of Aristotelianism were being laid. The evidence for this important development, hitherto quite scattered and obscure, can now be thoroughly studied through the translations and discussions Professor Sharples provides in this splendid source book. By organizing the material under the headings of logic and ontology, ethics, and physics, he has made it possible to get a clear grasp of the principal themes and philosophical issues of this Peripatetic tradition. His book is a major achievement.' A. A. Long, University of California, Berkeley
