Epicureanism is a Greek school holding that pleasure is the highest good, where pleasure means the absence of bodily pain and mental disturbance rather than indulgence.

Epicurus

Epicurus (341–270 BC) taught in a garden outside Athens, admitting women and slaves, which was unusual enough to attract hostile comment. His surviving work is fragmentary — three letters and collections of maxims — and the fullest presentation of the system is the Latin poem of Lucretius, On the Nature of Things, written two centuries later.

The ethics

Pleasure is the natural goal, and the Epicurean analysis of it is austere. Desires divide into the natural and necessary (food, shelter, friendship), the natural and unnecessary (luxury), and the empty (fame, unlimited wealth). The last group is unlimited by definition and so cannot be satisfied, which makes pursuing them a reliable source of pain.

The goal is ataraxia, freedom from disturbance, achieved by satisfying simple needs and eliminating the fears that produce unhappiness. Friendship is treated as the greatest contributor to a life well lived.

The physics

The ethics rests on atomism, taken from Democritus. The universe consists of atoms and void. The soul is material and disperses at death, which is the premise of the school's best-known argument: death is nothing to us, since where death is we are not, and where we are death is not. Fear of divine punishment is removed the same way, by arguing that the gods take no interest in human affairs.

Reputation

"Epicurean" came to mean devoted to fine food and comfort, which reverses the doctrine. Epicurus recommended bread and water as the basis of diet and treated luxury as a habit that raises the cost of contentment. The school's rivalry with Stoicism shaped much of later Hellenistic ethics.
