The word eudaimonism comes from the Greek word for happiness (eudaimonia), and refers to any conception of ethics that puts human happiness and the complete life of the individual at the center of ethical concern. This is solely a technical term and has no popular equivalent, though sometimes humanism comes close. Aristotle is the model eudaimonist, and really the founder of eudaimonism. By contrast, note that existentialism rejects happiness as a bourgeois fantasy, and that even Stoicism and Epicureanism really turn their backs on eudaimonism since they don't advocate individual fulfillment but only the lack of emotion or pain.
