Eudaimonia is a classical Greek word commonly translated as ‘happiness’. Etymologically, it consists of the word “eu” (”good” or “well being”) and “daimōn” (”spirit” or “minor deity”, used by extension to mean one’s lot or fortune). Although popular usage of the term happiness refers to a state of mind, related to joy or pleasure, eudaimonia rarely describes a state of mind, and the less subjective “human flourishing” is therefore often preferred as a translation . . .

According to Aristotle, the hierarchy of human purposes aim at eudaimonia as the highest, most inclusive end. This is the end that everyone in fact aims at, and it is the only end towards which it is worth undertaking means. Eudaimonia is constituted, according to Aristotle, not by honor, or wealth, or power, but by rational activity in accordance with excellence over a complete life. Such activity manifests the virtues of character, including courage, honesty, pride, friendliness, and wittiness; the intellectual virtues, such as rationality in judgment; and it also includes non-sacrificial (i.e., mutually beneficial) friendships and scientific knowledge (knowledge of things that are fundamental and/or unchanging is the best).
