Information:  - Epicurus (or  "ally, comrade"; 341270 BC) 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.  - Epicureanism is a system of philosophy based upon the teachings of the ancient Greek philosopher Epicurus, founded around 307 BC. 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 Aristippusabout whom very little is knownEpicurus believed that what he called "pleasure" was the greatest good, but that the way to attain such pleasure was to live modestly, to gain knowledge of the workings of the world, and to limit one's desires. This would lead one to attain a state of tranquility ("ataraxia") and freedom from fear as well as an absence of bodily pain ("aponia"). The combination of these two states constitutes happiness in its highest form. Although Epicureanism is a form of hedonism insofar as it declares pleasure to be its sole intrinsic goal, the concept that the absence of pain and fear constitutes the greatest pleasure, and its advocacy of a simple life, make it very different from "hedonism" as it is colloquially understood.  - Themista of Lampsacus , the wife of Leonteus , was a student of Epicurus , early in the 3rd century BCE . Epicurus ' school was unusual in the 3rd century , in that it allowed women to attend , and we also hear of Leontion attending Epicurus ' school around the same time . Cicero ridicules Epicurus for writing `` countless volumes in praise of Themista , '' instead of more worthy men such as Miltiades , Themistocles or Epaminondas . Themista and Leonteus named their son Epicurus .  - Marcus Tullius Cicero ( "Kikern"; 3 January 106 BC  7 December 43 BC) was a Roman philosopher, politician, lawyer, orator, political theorist, consul, and constitutionalist. He came from a wealthy municipal family of the Roman equestrian order, and is considered one of Rome's greatest orators and prose stylists.
