Our dealings with our enemy should be considered with more delicacy than our dealings with a friend. This fact is generally overlooked by man, and he deals in any way with an enemy, while he is considerate to a friend. Sometimes one insults one's enemy, spoiling thereby one's own habit, and making the enemy still more insulting. Sometimes by constantly dwelling on the faults of the enemy one impresses one's own soul with the same faults, and focuses them upon the soul of the enemy; if he lacks these faults, they may by reflection develop in him and cause him to become a still more bitter enemy.
