Review from previous edition This excellent book provides a number of new historical and exegetical takes on an important chapter in Hellenistic epistemology. Allen's ideas will be at the centre of future debates in the field. His arguments are not conclusive, and the reader may not find them all convincing, but such is the nature of Hellenistic epistemology.
