PT Journal AU Cajthaml, M TI The Role of Happiness in Moral Motivation. A Discussion in Contemporary Ethics SO Aither PY 2025 BP 24 EP 35 VL 17 IS 2 DI 10.5507/aither.2025.005 AB This paper analyses the role of happiness in moral motivation within the eudaimonistic tradition. 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.
