What are the motifs in Augustine of Hippo: A Biography, by Peter Brown by Peter Brown?

Augustine's development as a philosopher is a recurring idea in the book. Augustine is a perfect example of how much a fertile mind can benefit from a strong education. He first gained his active interest in formal philosophy through the works of Cicero. Augustine could not read Greek, which made him very limited in what greats he could study. Through practice, family and experience in his early life he was exposed to 4th century Christianity, a Catholic form.
