CHRYSIPPUS (c. 280-2o6 B.c.)  , Greek philosopher, the third great leader of the Stoics . A native of Soli in Cilicia (Diog . Laert. vii . 179), he was robbed of his property and came to Athens, where he studied possibly under Zeno, certainly under Cleanthes . It is said also that he became a pupil of Arcesilaus and Lacydes, heads of the Middle Academy . This impartiality in his early studies is the key of his philosophic work, the dominant characteristic of which is comprehensiveness rather than originality . He took the doctrines of Zeno and Cleanthes and crystallized them into a definite system; he further defended them against the attacks of the Academy . His polemic skill earned for him the title of the " Column of the Portico." Diogenes Laertius says, " If the gods use dialectic, they can use none other than that of Chrysippus "; ei pi 'yap iv X Quit &v ilv ZTO& (" Without Chrysippus, there had been no Porch ") . He excelled in logic, the theory of knowledge, ethics and physics . His relations with Cleanthes, contemporaneously criticized by Antipater, are considered under Sroics . He is said to have composed seven hundred and fifty treatises, fragments alone of which survive . Their style, we are told, was unpolished and arid in the extreme, while the argument was lucid and impartial .
