This new edition of Hellenistic Philosophy–including nearly 100 pages of additional materia–offers the first English translation of the account of Stoic ethics by Arius Didymus, substantial new sources on Epicureanism, Stoicism, and Scepticism, expanded representation of Plutarch and Cicero, and a fuller presentation of papyrological evidence. Inwood and Gerson maintain the standard of consistency and accuracy that distinguished their translations in the first edition, while regrouping some material into larger, more thematically connected passages. This edition is further enhanced by a new, more spacious page design.
