As they work their way through the seminal figures of Western history, introductory courses on Philosophy continue to include Augustine of Hippo, sandwiching him between Aristotle and Thomas Aquinas, who each lived from seven-to-eight-hundred years from him in either chronological direction. One of the principal difficulties in engaging with Augustine on some of the classical loci of philosophy, however, is that he does not always have works dedicated to these topics. On these matters, one must glean his position from other works. Augustine’s position on political philosophy is one such subject. Thankfully, Robert A. Markus’ Saeculum: History and Society in the Theology of St. Augustine, Revised Edition (New York: Cambridge, 2007) goes a long way towards filling this vacuum.
