Nevertheless he had taken a great step in rejecting the fundamental dogma of Manicheeism--the double Principle of good and evil. Henceforth for Augustin there exists only one Principle, unique and incorruptible--the Good, which is God. But his view of this divine substance is still quite materialistic, to such an extent is he governed by his senses. In his thought, it is corporeal, spatial, and infinite. He pictures it as a kind of limitless sea, wherein is a huge sponge bathing the world that it pervades throughout.... He was at this point, when one of his acquaintances, "a man puffed up with immense vanity," gave him some of the Dialogues of Plato, translated into Latin by the famous rhetorician Victorinus Afer. It is worth noting, as we pass, that Augustin, now thirty-two years old, a rhetorician by profession and a philosopher by taste, had not yet read Plato. This is yet another proof to what extent the instruction of the ancients was oral, resembling in this the Mussulmans' instruction of to-day. Up to now, he had only known Plato by hearsay. He read him, and it was as a revelation. He learned that a reality could exist without diffusion through space. He saw God as unextended and yet infinite. The sense of the divine Soul was given to him. Then the primordial necessity of the Mediator or Word was borne in upon his mind. It is the Word which has created the world. It is through the Word that the world, and God, and all things, including ourselves, become comprehensible to us. What an astonishment! Plato corresponded with St. John! "In the beginning was the Word"--_in principio erat verbum_--said the fourth Gospel. But it was not only an Evangelist that Augustin discovered in the Platonist dialogues, it was almost all the essential part of the doctrine of Christ. He saw plainly the profound differences, but for the moment he was struck by the resemblances, and they carried him away. What delighted him, first of all, is the beauty of the world, constructed after His own likeness by the Demiurgus. God is Beauty; the world is fair as He who made it. This metaphysical vision entranced Augustin; his whole heart leaped towards this ineffably beautiful Divinity. Carried away by enthusiasm he cries: "I marvelled to find that now I loved Thee, O my God, and not a phantasm in Thy stead. If I was not yet in a state to enjoy Thee, _I was swept up to Thee by Thy beauty_."
