Letters 28.9

It is time to stop, but not before I have paid duty. “The knowledge of sin is the beginning of salvation.” This saying of Epicurus seems to me to be a noble one. For he who does not know that he has sinned does not desire correction; you must discover yourself in the wrong before you can reform yourself.
