"It's Your Fault That I'm This way"

Passage from the text:
"But I was all words, and stupidly I used to ask them, 'If, as you say, God made the soul, why does it err?' Yet I did not like them to ask me in return, 'If what you say is true, why does God err?'"
- Book IV Chapter XV

Commentary:
At first I had to re-read the above as it made no sense at all upon first glance. But then, what sense it did make! St.Augustine, here, was being the big shot orator and arguer that he is, questioning the 500 A.D. Christians of Carthage about the perfection of God. The line of thought goes: if God is perfect, what he makes should also be perfect. Why, then, are we not perfect? This alone would be a sure-fire argument against the existence of God. But, unlike many modern-day Christians, those persons that Augustine poses the question to are astute enough to know that the two things, God and creation, are independent of each other when it comes to qualities like goodness or perfection. I think it's a clever little repartee worthy of musing: We're not perfect and it's not God's fault.
