The mind of Augustine, however, was logical, and naturally profound; and at last he became dissatisfied with the nonsense with which plausible pretenders ensnared him. He was then what we should call a schoolmaster, or what some would call a professor, and taught rhetoric for his support, which was a lucrative and honorable calling. He became a master of words. From words he ascended to definitions, and like all true inquirers began to love the definite, the precise. He wanted a basis to stand upon. He sought certitudes,--elemental truths which sophistry could not cover up. Then the Manicheans could no longer satisfy him. He had doubts, difficulties, which no Manichean could explain, not even Dr. Faustus of Mileve, the great oracle and leader of the sect,--a subtle dialectician and brilliant orator, but without depth or earnestness,--whom he compares to a cup-bearer presenting a costly goblet, but without anything in it. And when it became clear that this high-priest of pretended wisdom was ignorant of the things in which he was supposed to excel, but which Augustine himself had already learned, his disappointment was so great that he lost faith both in the teacher and his doctrines. Thus this Faustus, "neither willing nor witting it," was the very man who loosened the net which had ensnared Augustine for so many years. He was now thirty years of age, and had taught rhetoric in Carthage, the capital of Northern Africa, with brilliant success, for three years; but panting for new honors or for new truth, he removed to Rome, to pursue both his profession and his philosophical studies. He entered the capital of the world in the height of its material glories, but in the decline of its political importance, when Damasus occupied the episcopal throne, and Saint Jerome was explaining the Scriptures to the high-born ladies of Mount Aventine, who grouped around him,--women like Paula, Fabiola, and Marcella. Augustine knew none of these illustrious people. He lodged with a Manichean, and still frequented the meetings of the sect; convinced, indeed, that the truth was not with them, but despairing to find it elsewhere. In this state of mind he was drawn to the doctrines of the New Academy,--or, as Augustine in his "Confessions" calls them, the Academics,--whose representatives, Arcesilaus and Carneades, also made great pretensions, but denied the possibility of arriving at absolute truth,--aiming only at probability. However lofty the speculations of these philosophers, they were sceptical in their tendency. They furnished no anchor for such an earnest thinker as Augustine. They gave him no consolation. Yet his dislike of Christianity remained.
