I had no motive for my wickedness except for wickedness itself. It was foul, and I loved it. I loved the self-destruction, I loved my fall, not the objecto for which I had fallen but my fall itself. My depraved soul leaped down from your firmament to ruin. I was seeking not to gain anything by shameful means, but shame for its own sake. (Augustine, Confessions 2.4(9); trans. Henry Chadwick).
What was Augustine's great depravity in his soul? What great sin had he committed for the sake of wickedness and shame itself? A fall that he enjoyed not for the end, but for the fall itself? He stole a pear. Can you think of a more wicked and evil act?
(An extra note: sadly, the translator of these lines, Henry Chadwick, died last year. He will be sorely missed.)
