What, indeed, is more romantic than this wandering life of rhetorician and student that the youthful Augustin led, from Thagaste to Carthage, from Carthage to Milan and to Rome—begun in the pleasures and tumult of great cities, and ending in the penitence, the silence, and recollection of a monastery? And again, what drama is more full of colour and more profitable to consider than that last agony of the Empire, of which Augustin was a spectator, and, with all his heart faithful to Rome, would have prevented if he could? And then, what tragedy more stirring and painful than the crisis of soul and conscience which tore his life? Well may it be said that, regarded as a whole, the life of Augustin was but a continual spiritual struggle, a battle of the soul. It is the battle of every moment, the never-ceasing combat of body and spirit, which the poets of that time dramatized, and which is the history of the Christian of all times. The stake of the battle is a soul. The upshot is the final triumph, the redemption of a soul. (Summary from The Prologue)
