Maslow offered repeated and trenchant criticism of mainstream psychoanalysis for fixating on the “nasty . . . ‘dark, dirty’” elements of human personality (Maslow, 1971, p. 310). For precisely this reason, Maslow helped launch what he called the “Third Force” of humanistic psychology, to transcend the reductionism of both behaviorism and psychoanalysis. Central to this focus was the investiga-tion of peak-experiences as a foundation of healthy psychological function-ing and optimization of one’s full potentialities.
