Ancient Greek philosopher as well as the founder of the school of philosophy called Epicureanism. 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.
