After a look at Voegeli's notion of "symbol," it offers definitions of analogy and metaphor, then goes on to introduce notions of "existential metaphors" and "primal metaphors," the latter defined as those pertaining to transcendence or to human participation in transcendence. Voegelin's choice to rely in his philosophy on primal metaphors such as "the Beyond" and " the In-Between" is examined, and this choice is finally related to his openness to and analyses of myth.
