From Street Philosophy to Stoic Ethics

Cynicism's most consequential legacy may not be its own tradition, which never developed formal institutions or a settled body of doctrine, but the philosophy it helped produce through a single teaching relationship. Zeno of Citium, a merchant from Cyprus whose ship was wrecked near Athens, is reported to have studied for years under the Cynic teacher Crates of Thebes before founding Stoicism, and Stoic ethics retained a clearly Cynic inheritance in its insistence that virtue alone is good, that external goods such as wealth, health and reputation are strictly indifferent to happiness, and that a wise person should be self sufficient and undisturbed by fortune. Where the Stoics differed from their Cynic root was in refusing the Cynic style of public shamelessness and deliberate social provocation, developing instead a more systematic physics and logic alongside the shared ethics, and building formal schools with settled teaching rather than living as itinerant provocateurs. Later Roman writers, including the satirist Lucian, continued to describe practicing Cynics for centuries after the school's classical period, suggesting that Cynicism persisted as a recognizable way of life, associated with a distinctive cloak, staff and begging bag, well into the Roman imperial period even without ever becoming an organized school in the way Platonism or the Lyceum were.
