A series of lectures on the political aspects of St. Augustine's "City of God" by John Neville Figgis.
Excerpts:
...There are those who are for treating S. Augustine as the typical example of the medieval temperament with its heights and depths, its glories and splendors of imagination, its dialectical ingenuity and its irrational superstitions. Others see in S. Augustine essentially a man of the antique world. They do not deny to him real influence upon later times. Who can? But they are inclined to minimize this; at least in matters of social and political importance.
