Meditation 7.26

26. When a man offends against you, think at once what conception of good or ill it was which made him offend. And, seeing this, you will pity him, and feel neither surprise nor anger. For you yourself still conceive either the same object as he does to be good, or something else of the same type; you are bound, therefore, to excuse him. If, on the other hand, you no longer conceive things of that kind to be goods or ills, you will the more easily be kind to one whose eye is darkened.
