<P> Epicureanism is a system of philosophy based upon the teachings of the ancient Greek philosopher Epicurus, founded around 307 BC . Epicurus was an atomic materialist, following in the steps of Democritus . His materialism led him to a general attack on superstition and divine intervention . Following Aristippus--about whom very little is known--Epicurus believed that what he called "pleasure" (ἡδονή) was the greatest good, but that the way to attain such pleasure was to live modestly, to gain knowledge of the workings of the world, and to limit one's desires . This would lead one to attain a state of tranquility (ataraxia) and freedom from fear as well as an absence of bodily pain (aponia). The combination of these two states constitutes happiness in its highest form . Although Epicureanism is a form of hedonism insofar as it declares pleasure to be its sole intrinsic goal, the concept that the absence of pain and fear constitutes the greatest pleasure, and its advocacy of a simple life, make it very different from "hedonism" as colloquially understood . </P> <P> Epicureanism was originally a challenge to Platonism, though later it became the main opponent of Stoicism . Epicurus and his followers shunned politics . After the death of Epicurus, his school was headed by Hermarchus; later many Epicurean societies flourished in the Late Hellenistic era and during the Roman era (such as those in Antiochia, Alexandria, Rhodes, and Ercolano). Its best - known Roman proponent was the poet Lucretius . By the end of the Roman Empire, being opposed by philosophies (mainly Neo-Platonism) that were now in the ascendant, Epicureanism had all but died out, and would be resurrected in the Age of Enlightenment . </P>
