Augustine's amazing intelligence and education allowed him to produce books which are still standards in philosophy and logic. Although he wrote them over a thousand years ago, some of his personal experiences seem very modern. Going off to the university is still a major turning-point in a person's life.
Augustine’s education also gave him a more cosmopolitan viewpoint. At fifteen, he was sent to Carthage, a big city with theaters, universities, intellectuals, and, in his opinion, great temptations. He wrote, in Confessions, his dynamic autobiography, “I came to Carthage and all around me hissed a cauldron of illicit loves.” Augustine even got caught up in a more worldly and sinful lifestyle. He was in close contact with a lot of different groups of people and many different religious groups. This experience would prove invaluable in appealing to different groups and understanding their viewpoints.
Technically, Carthage had schools, not universities, because the first universities wouldn't appear for another five hundred years. But Augustine's experience was one which reflects the universal human nature.
