Augustine's personal testimony
<p>"There was a pear tree near our vineyard, laden with fruit. One stormy night we rascally youths set out to rob it and carry our spoils away. We took off a huge load of pears—not to feast upon ourselves, but to throw them to the pigs, though we ate just enough to have the pleasure of forbidden fruit. They were nice pears, but it was not the pears that my wretched soul coveted, for I had plenty better at home. I picked them simply in order to become a thief. The only feast I got was a feast of iniquity, and that I enjoyed to the full. What was it that I loved in that theft? Was it the pleasure of acting against the law, in order that I, a prisoner under rules, might have a maimed counterfeit of freedom by doing what was forbidden, with a dim similitude of impotence?... The desire to steal was awakened simply by the prohibition of stealing."
