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 shall be alike brought before the judgment-seat, and the true City of God shall appear…The work of St. Augustine is a curious repertory of antiquarian learning and quotations, deeply penetrated with Christian ethics, but showing little power of reasoning, and a slender knowledge of the Greek literature and language. He was a great genius, and a noble character, yet hardly capable of feeling or understanding anything external to his own theology. Of all the ancient philosophers he is most attracted by Plato, though he is very slightly acquainted with his writings. He is inclined to believe that the idea of creation in the Timaeus is derived from the narrative in Genesis; and he is strangely taken with the coincidence (?) of Plato’s saying that ‘the philosopher is the lover of God,’ and the words of the Book of Exodus in which God reveals himself to Moses (Exod.) He dwells at length on miracles performed in his own day, of which the evidence is regarded by him as irresistible. He speaks in a very interesting manner of the beauty and utility of nature and of the human frame, which he conceives to afford a foretaste of the heavenly state and of the resurrection of the body. The book is not really what to most persons the title of it would imply, and belongs to an age which has passed away. But it contains many fine passages and thoughts which are for all time.
The short treatise de Monarchia of Dante is by far the most remarkable of mediaeval ideals, and bears the impress of the great genius in whom Italy and the Middle Ages are so vividly reflected. It is the vision of an Universal Empire, which is supposed to be the natural and necessary government of the world, having a divine authority distinct from the Papacy, yet coextensive with it. It is not ‘the ghost of the dead Roman Empire sitting crowned upon the grave thereof,’ but the legitimate heir and successor of it, justified by the ancient virtues of the Romans and the beneficence of their rule. Their right to be the governors of the world is also confirmed by the testimony of miracles, and acknowledged by St. Paul when he appealed to Caesar, and even more emphatically by Christ Himself, Who could not have made atonement for the sins of men if He had not been condemned by a divinely authorized tribunal. The necessity for the establishment of an Universal Empire is proved partly by a priori arguments such as the unity of God and the unity of the family or nation; partly by perversions of Scripture and history, by false analogies of nature, by misapplied quotations from the classics, and by odd scraps and commonplaces of logic, showing a familiar but by no means exact knowledge of Aristotle (of Plato there is none). But a more convincing argument still is the miserable state of the world, which he touchingly describes. He sees no hope of happiness or peace for mankind until all nations of
