Eric Voegelin’s life work is best understood as a “zetema,” a philosopher’s life-long quest for truth, one that underwent substantial changes during the final phase of his quest. As Michael Franz explains in his Introduction, Voegelin’s last essays have not received the critical attention they deserve, yet they contain the most refined formulations of his thought. Franz has succeeded in enlisting scholars thoroughly aquatinted with Voegelin’s voluminous publications who are well qualified to analyze the theoretical advances in these last essays and relate them to the better-known, previous stages of his exploration of orders and disorders of the soul and of society.—Stephen A.
