Purpose. The paper is aimed to explicate a recently emerging anthropological model of homo eudaimonicus from its secular framework perspective. Theoretical basis. Secularity is considered in three aspects with reference to Taylor’s and Habermas’ ideas: as a common public sphere, as a phenomenological experience of living in a Secular Age, and as a background for happiness to become a major common value among other secular values in the Age of Authenticity. The modifications of happiness interpretation are traced from Early Modernity (...) till nowadays. The preconditions of the contemporary appeal to Aristotle’s eudaimonic theory of happiness are elucidated. The main characteristics of homo economicus anthropological model and reasons for its collapse in the contemporary world are analyzed. Specificities of the contemporary interpretations of eudaimonia are described with reference to the works of MacIntyre, Haybron, Hamilton, Kekes, Melnick, and others. A moral foundation and a behavioral strategy of homo eudaimonicus model are expounded and the role of this model in the life of a contemporary individual person and society is revealed. Originality. For the first time in the Ukrainian philosophical discourse, it is shown how secular ethics enables the rise of a new homo eudaimonicus model within a sphere of secularity; and it is argued that homo eudaimonicus is the result of overcoming the values crisis. It is revealed how homo eudaimonicus along with being descriptive becomes also a normative model of a new effective behavior strategy of a contemporary person facing the current social, economic, political, and environmental challenges. Conclusions. According to the contemporary interpretation, happiness as eudaimonia is a combination of the good life and the meaningful life; it is a human flourishing in this world through the accomplishment of a person’s life plan in the sphere of secularity. Homo eudaimonicus manifests the overcoming of values crisis and the rediscovery of purpose and meaning, this time on the secular basis. Homo eudaimonicus implies the realization of a person’s project of a happy and fulfilling life through moral behavior and socially useful activities. (shrink)
