succeeded Cleanthes as head of the Stoa in 232 (see Stoicism). He came to Athens c.260 and studied in the sceptical Academy, learning the importance of argument for and against given positions. He studied under Cleanthes and adopted the Stoic position, defending it voluminously. He is said to have told Cleanthes that he needed only to know the positions, and would provide the proofs himself. Another saying has it that ‘if there had been no Chrysippus, there would have been no Stoa’; his extensive writings (we have a partial list in Diogenes 4 Laertius) argued for all aspects of Stoicism so competently that his position became Stoic orthodoxy, eclipsing earlier Stoics other than Zeno 2, whose views Chrysippus took pains to preserve and explain. Through him Stoicism became a well‐argued position, with extensive resources for debate on many fronts. He esp. developed Stoic logic.
