The book addresses the question of the alleged Heracliteanism of the Sceptic philosopher Aenesidemus of Cnossus.

This book provides the first edition of all the testimonia on the Sceptic philosopher Aenesidemus of Cnossus, who is deemed to be the source of Sextus Empiricus, the main surviving authority on ancient Scepticism. It provides an extensive philosophical and historical commentary, and throws light on a series of questions concerning the philosophy of the late Academy, Stoic Heracliteanism, and the interaction between medicine and philosophy in the late Hellenistic era. It will be an essential reference work for all those (...) scholars and students dealing with the history of ancient Scepticism. (shrink)

It is an established Hellenistic topos that philosophy is the ‘medicine’ of the soul, in charge of ‘healing’ the soul in the same way as medicine is in charge of healing the body. The ‘diseases’ of the soul deemed to be in need of healing are its passions, that is, its fears and desires, and the moral ‘health’ that philosophers pledge to grant their followers is freedom from passions and hence peace of mind.
