Misfortune seldom intrudes upon the wise man; his greatest and highest interests are directed by reason throughout the course of life.

Epicurus

Epicurus (Ancient Greek: Ἐπίκουρος, Epikouros, « ally, comrade »; 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.
