Happiness is the ultimate end and purpose of human existence “eudaimonia”

Aristotle (350BC)

Two of the most influential forms are those of Aristotle and the Stoics. Aristotle takes virtue and its exercise to be the most important constituent in eudaimonia but acknowledges also the importance of external goods such as health, wealth, and beauty. By contrast, the Stoics make virtue necessary and sufficient for eudaimonia and thus deny the necessity of external goods.
