Epicurus Epicurus ( or ; Greek: Ἐπίκουρος, "Epíkouros" , "ally, comrade"; 341–270 BC) was an ancient Greek philosopher who founded 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.
Platonism Platonism, rendered as a proper noun, is the philosophy of Plato or the name of other philosophical systems considered closely derived from it. In narrower usage, platonism, rendered as a common noun (with a lower case "p" subject to sentence case), refers to the philosophy that affirms the existence of abstract objects, which are asserted to "exist" in a "third realm" distinct both from the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. Lower case "platonists" need not accept any of the doctrines of Plato.
