to the vision of Er; it is only a dream, and hardly allows the reader to suppose that the writer believes in his own creation. Whether his dialogues were framed on the model of the lost dialogues of Aristotle, as he himself tells us, or of Plato, to which they bear many superficial resemblances, he is still the Roman orator; he is not conversing, but making speeches, and is never able to mould the intractable Latin to the grace and ease of the Greek Platonic dialogue. But if he is defective in form, much more is he inferior to the Greek in matter; he nowhere in his philosophical writings leaves upon our minds the impression of an original thinker. Plato’s Republic has been said to be a church and not a state; and such an ideal of a city in the heavens has always hovered over the Christian world, and is embodied in St. Augustine’s ‘De Civitate Dei,’ which is suggested by the decay and fall of the Roman Empire, much in the same manner in which we may imagine the Republic of Plato to have been influenced by the decline of Greek politics in the writer’s own age. The difference is that in the time of Plato the degeneracy, though certain, was gradual and insensible: whereas the taking of Rome by the Goths stirred like an earthquake the age of St. Augustine. Men were inclined to believe that the overthrow of the city was to be ascribed to the anger felt by the old Roman deities at the neglect of their worship. St. Augustine maintains the opposite thesis; he argues that the destruction of the Roman Empire is due, not to the rise of Christianity, but to the vices of Paganism. He wanders over Roman history, and over Greek philosophy and mythology, and finds everywhere crime, impiety and falsehood. He compares the worst parts of the Gentile religions with the best elements of the faith of Christ. He shows nothing of the spirit which led others of the early Christian Fathers to recognize in the writings of the Greek philosophers the power of the divine truth. He traces the parallel of the kingdom of God, that is, the history of the Jews, contained in their scriptures, and of the kingdoms of the world, which are found in gentile writers, and pursues them both into an ideal future. It need hardly be remarked that his use both of Greek and of Roman historians and of the sacred writings of the Jews is wholly uncritical. The heathen mythology, the Sybilline oracles, the myths of Plato, the dreams of Neo-Platonists are equally regarded by him as matter of fact. He must be acknowledged to be a strictly polemical or controversial writer who makes the best of everything on one side and the worst of everything on the other. He has no sympathy with the old Roman life as Plato has with Greek life, nor has he any idea of the ecclesiastical kingdom which was to arise out of the ruins of the Roman empire. He is not blind to the defects of the Christian Church, and looks forward to a time when Christian and Pagan
