Eudaimonia (/juːdɪˈmoʊniə/; Ancient Greek: εὐδαιμονία [eu̯dai̯moníaː]), sometimes anglicized as eudaemonia or eudemonia, is a Greek word literally translating to the state or condition of 'good spirit', and which is commonly translated as 'happiness' or 'welfare'.
In the works of Aristotle, eudaimonia was the term for the highest human good in older Greek tradition. It is the aim of practical philosophy-prudence, including ethics and political philosophy, to consider and experience what this state really is and how it can be achieved. It is thus a central concept in Aristotelian ethics and subsequent Hellenistic philosophy, along with the terms aretē (most often translated as 'virtue' or 'excellence') and phronesis ('practical or ethical wisdom').[1]
Discussion of the links between ēthikē aretē (virtue of character) and eudaimonia (happiness) is one of the central concerns of ancient ethics, and a subject of disagreement. As a result, there are many varieties of eudaimonism.
But although modern virtue ethics does not have to take the form known as "neo-Aristotelian", almost any modern version still shows that its roots are in ancient Greek philosophy by the employment of three concepts derived from it. These are areté (excellence or virtue), phronesis (practical or moral wisdom), and eudaimonia (usually translated as happiness or flourishing). As modern virtue ethics has grown and more people have become familiar with its literature, the understanding of these terms has increased, but it is still the case that readers familiar only with modern philosophy tend to misinterpret them.
