Principal Doctrines, The

For Epicurus, the purpose of philosophy was to attain the happy, tranquil life, characterized by peace and freedom from fear, 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 neither reward nor punish humans; the universe is infinite and eternal; and events in the world are ultimately based on the motions and interactions of atoms.Although much of Epicurus' written work has been lost, his surviving principal doctrines form a complete foundation of his teaching.
