It addresses the Aristotelian-Thomistic tension between choosing virtuous action for its own sake and for the sake of eudaimonia. Through a critical examination of Josef Seifert's two-motive theory, Jeff D'Souza's altruistic eudaimonism, and Chris Toner's excellence-prior eudaimonism, I argue that Seifert's phenomenological framework provides the most coherent account. It distinguishes between a primary, value-responsive motive directed toward morally relevant goods and a secondary, subordinate desire for true happiness. This dual structure retains the legitimacy of eudaimonistic motivation while avoiding both the self-referentiality characteristic of traditional eudaimonism and the excessive other-centredness of its modern revisions.
