Epicurus (Samos, 341 BCE - Athens, 270 BCE; 72 years) was an ancient Greek philosopher and the founder of the school of philosophy called Epicureanism. Only a few fragments and letters remain of Epicurus's 300 written works. Much of what is known about Epicurean philosophy derives from later followers and commentators.
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 the greatest good was to seek modest pleasures in order to attain a state of tranquillity and freedom from fear (ataraxia) as well as absence of bodily pain (aponia) through knowledge of the workings of the world and the limits of our desires.
