“The truth of the tragedy is action itself, that is, action on the new, differentiated level of a movement in the soul that culminates in the decision (prohairesis) of a mature, responsible man. The newly discovered humanity of the soul expands into the realm of action. Tragedy as a form is the study of the human soul in the process of making decisions, while the single tragedies construct conditions and experimental situations, in which a fully developed, self-conscious soul is forced into action.”——Erik Voegelin, The Collected Work of Eric Voegelin, vol.15:Order and History, vol.Ⅱ, The World of the Polis,Athanasios Moulakis(ed.), Columbia:University of Missouri Press, 2000, p. 321
