Chrysippus

The third scholarch (school leader) of the Stoa and the most important systematic thinker of the early Stoa.

Chrysippus (280–207 BC) was the successor of Cleanthes and shaped Stoic philosophy through his detailed psychological and logical systematization. He developed in particular the theory of the passions, according to which passions are judgments, thereby creating the theoretical foundation for the distinction between false emotions (Pathē) and well-ordered emotions (Eupatheiai). His work was so influential that it was said: "Without Chrysippus, there would be no Stoa."
