J. Fillion-Lahille has argued that the first book of the De Ira was inspired by the Stoic philosopher Chrysippus' (3rd-century BCE) treatise On Passions (Peri Pathôn), whereas the second and third drew mainly from a later Stoic philosopher, Posidonius (1st-century BCE), who had also written a treatise On Passions and differed from Chrysippus in giving a bigger role to irrational aspects of the soul.[1] However, more recent research has shown that this view of Posidonius' criticism of Chrysippus was mainly due to Galen's (our main witness for Posidonius' and Chrysippus' now lost works) systematic distorsion of their thinking, and that Posidonius' theory of emotions was actually substantially identical with that of Chrysippus.[2] In consequence, although Seneca may have used both treatises by Chrysippus and Posidonius, his main inspiration is now thought to be chrysippean.[3] ./cache/en-wikipedia-org-3534.html ./txt/en-wikipedia-org-3534.txt
