epicureanism (ĕpˌĭkyŏrēˈənĭzˌəm) [key], philosophy that follows the teachings of Epicurus, who held that pleasure is the end of all morality and that real pleasure is attained through a life of prudence, honor, and justice. The philosophy was popular throughout the ancient world; it was spread by the successors of Epicurus, who included Polystratus, Zeno of Sidon, and Philodemus of Gadara. Only in later times did epicureanism come to mean devotion to extravagant pleasure.
