Epicureanism is a philosophy based on the teachings of Epicurus. Epicurus felt that the highest good was the pursuit of pleasure. According to Epicurus, a person could attain pleasure by living modestly, learning about the world and curbing one's excessive desires. If a person could do this, he would be free from anxiety and pain and would also experience happiness.
This philosophy differs from Hedonism in that it advocates a simple life, rather than a life of consumption and over-indulgence. Epicureanism also states that the gods are not involved with human lives and that everything, including humans, the gods and the soul is made up of atoms. Epicureanism was founded sometime around 307 BC and it flourished for 700 years.
