Epicurus (341 BCE _ 270 BCE) was an ancient Greek philosopher as well as the founder of the school of philosophy called Epicureanism. Only a few fragments and letters of Epicurus's 300 written works remain. Much of what is known about Epicurean philosophy derives from later followers and commentators. For Epicurus, the purpose of philosophy was to attain the happy, tranquil life, characterized by ataraxia_peace and freedom from fear_and aponia_the absence of pain_and by living a self-sufficient life surrounded by friends. He taught that pleasure and pain are the measures of what is good and evil; death is the end of both body and soul and should therefore not be feared; the gods do not reward or punish humans; the universe is infinite and eternal; and events in the world are ultimately based on the motions and interactions of atoms moving in empty space.
