text: 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. Some boast of their faults. Do you think that the man has any thought of mending his ways who counts over his vices as if they were virtues? Therefore, as far as possible, prove yourself guilty, hunt up charges against yourself; play the part, first of accuser, then of judge, last of intercessor. At times be harsh with yourself. Farewell.
