St. Augustine wrote that he once stole some peaches. When he reflected on that experience he observed that he got a rush from breaking the rules. He then concluded that he broke the rules for the sake of breaking the rules and that more broadly this meant that at least some human sins are committed for the sake of sin. I think that St. Augustine was using this example to refute the Socratic claim that lack of knowledge was the cause of sin. Is St. Augustine's claim valid? Does it follow from the fact that he got excited from breaking the rules that he broke the rules for the sake of breaking the rules rather than the excitement it generated? Are there other reasons why breaking the rules might be exciting other than a desire to break the rules for its own sake? Maybe he got excitement from stealing the peaches because it was risky or because he wanted to challenge authority or to feel less confined by rules.
