The effect produced by this great work it is impossible to determine with accuracy. Beugnot, with an absoluteness which we should condemn as presumption in any less competent authority, declares that its effect can only have been very slight.14 Probably its effect would be silent and slow; telling first upon cultivated minds, and only indirectly upon the people. Certainly its effect must have been weakened by the interrupted manner of its publication. It is an easier task to estimate its intrinsic value. But on this also patristic and literary authorities widely differ. Dupin admits that it is very pleasant reading, owing to the surprising variety of matters which are introduced to illustrate and forward the argument, but censures the author for discussing very useless questions, and for adducing reasons which could satisfy no one who was not already convinced.15 Huet also speaks of the book as “un amas confus d’excellents materiaux; c’est de l’or en barre et en lingots.”16 L’Abbé Flottes censures these opinions as unjust, and cites with approbation the unqualified eulogy of Pressensé.17 But probably the popularity of the book is its best justification. This popularity may be measured by the circumstance that, between the year 1467 and the end of the fifteenth century, no fewer than twenty editions were called for, that is to say, a fresh edition every eighteen months.18 And in the interesting series of letters that passed between Ludovicus Vives and Erasmus, who had engaged him to write a commentary on the City of God for his edition of Augustine’s works, we find Vives pleading for a separate edition of this work, on the plea that, of all the writings of Augustine, it was almost the only one read by patristic students, and might therefore naturally be expected to have a much wider circulation.19
If it were asked to what this popularity is due, we should be disposed to attribute it mainly to the great variety of ideas, opinions, and facts that are here brought before the reader’s mind. Its importance as a contribution to the history of opinion cannot be overrated. We find in it not only indications or explicit enouncement of the author’s own views upon almost every important topic which occupied his thoughts, but also a compendious exhibition of the ideas which most powerfully influenced the life of that age. It thus becomes, as Poujoulat says, “comme l’encyclopédie du cinquième siècle.” All that is valuable, together with much indeed that is not so, in the religion and philosophy of the classical nations of antiquity, is reviewed. And on some branches of these subjects it has, in the judgment of one well qualified to judge, “preserved more than the whole surviving Latin literature.” It is true we are sometimes wearied by the too elaborate refutation of opinions which to a modern mind seem self-evident absurdities; but if these opinions were actually prevalent in the fifth century, the historical inquirer will not quarrel with the form in which his information is conveyed, nor will commit the absurdity of attributing to Augustine the foolishness of these opinions, but rather the credit of exploding them. That Augustine is a well-informed and impartial critic, is evinced by the courteousness and candour which he uniformly displays to his opponents, by the respect he won from the heathen themselves, and by his own early life. The most rigorous criticism has
