摘要
Aristotle's concept of eudaimonia and hedonic enjoyment constitute 2 philosophical conceptions of happiness. Two studies involving combined samples of undergraduate and graduate students (Study 1, N = 209; Study 2, N = 249) were undertaken to identify the convergent and divergent aspects of these constructs. As expected, there was a strong positive correlation between personal expressiveness (eudaimonia) and hedonic enjoyment. Analyses revealed significant differences between the 2 conceptions of happiness experienced in conjunction with activities for the variables of (a) opportunities for satisfaction, (b) strength of cognitive-affective components, (c) level of challenges, (d) level of skills, and (e) importance. It thus appears that the 2 conceptions of happiness are related but distinguishable and that personal expressiveness, but not hedonic enjoyment, is a signifier of success in the process of self-realization. The qualities deemed to represent optimal, healthy, or effective psychological functioning have been a perennial concern within personality psychology. However, work on optimal functioning has generally been carried out within diverse theoretical systems with few efforts made to interrelate or integrate concepts proposed as optimal within the different theories. Four such constructs are (a) a sense of personal identity (Erikson, 1963, 1968—ego analytic theory), (b) self-actualization (Maslow, 1968,1970—humanistic theory), (c) an internal locus of control (Rotter, 1966—social learning theory), and (d) principled moral reasoning (Gilligan, 1982, Kohlberg, 1969—cognitive developmental theory). In an analysis of the philosophical underpinnings of these constructs, I (Waterman, 1981, 1984) have demonstrated that they share individualistic philosophical assumptions regarding the role of self-realization as a component of optimal psychological functioning. The philosophical theory that corresponds to the perspectives advanced with regard to each of the four constructs, and that is foundational to claims made for each, is eudaimonism.
