Therefore, we place this next in order. Freedom from anger is an insatiable appetite for dishonour, just as in the vainglorious there is no unbounded desire for praise. Freedom from anger is victory over nature and insensibility to insults, acquired by struggles and sweat. Wrath is a desire for the injury of the one who has provoked you. Irascibility is the untimely blazing up of the heart.
Bitterness is a movement of displeasure seated in the soul.
Anger is an easily changeable movement of one's disposition and disfiguration of soul. If you want, or rather intend, to take a splinter out of another person, then do not hack at it with a stick instead of a lancet, for you will only drive it in deeper. And if even this is required, do it rarely, and not with your own hand. Let it be put to shame by the Prayer of Jesus which cannot be said with it. Some, for the sake of forgiveness, give themselves up to labours and struggles, but a man who is forgetful of wrongs excels them.
