- the philosophy of Epicurus or his school
- adherence to or practice of this philosophy
- A philosophy advanced by Epicurus that considered happiness, or the avoidance of pain and emotional disturbance, to be the highest good and that advocated the pursuit of pleasures that can be enjoyed in moderation.
- also epicureanism Devotion to a life of pleasure and luxury.
Modern accepted use of the terms epicurean and Epicureanism refers often to the appreciation of good food (gourmet), and luxury. This strays significantly from the original philoposhic intent of Epicureanism. The philosophy indeed elevated pleasure and happiness as the most worthy pursuit, but specifically warned against fine food, for it could lead to dissatisfaction later. Instead, the goal was a long-term pleasure, marked by serenity and temperance, achieved through moderation rather than indulging. Modern senses of gourmet, luxury, hedonism, sensual pleasure and lust are mostly in contrast with the original ancient teachings.
