The story of Augustine’s friend Alypius at the amphitheater is a good example of how Augustine believes sin works. When Augustine says that Alypius was presumptuous, he anticipates the argument that, having overcome his past obsession with gladiatorial games, Alypius should not have been afraid to attend the games again. Rather, Augustine says, Alypius assumed he could not be easily tempted by the sin around him—a form of pride that most often goes before a fall. Sin, Augustine thus suggests, is a perennial threat even to someone who is experienced at resisting it, if they don’t watch out. By mentioning Alypius and Nebridius in his life at Milan, Augustine shows that his journey to faith wasn’t a solitary one, but that the search for wisdom is often strengthened by community.
