This comprehensive sourcebook makes available in the original Latin and Greek the principal extant texts required for the study of the Stoic, Epicurean and sceptical schools of philosophy. The material is organised by schools, and within each school topics are treated thematically. The volume presents the same texts (with some additional passages) as are translated in The Hellenistic Philosophers, Volume 1. The authors provide their own critical apparatus, and also supply detailed notes on the more difficult texts. This volume is equipped with a large annotated bibliography.
