When any person does ill by you, or speaks ill of you, remember that he
acts or speaks from an impression that it is right for him to do so. Now
it is not possible that he should follow what appears right to you, but
only what appears so to himself. Therefore, if he judges from false
appearances, he is the person hurt, since he, too, is the person
deceived. For if anyone takes a true proposition to be false, the
proposition is not hurt, but only the man is deceived. Setting out, then,
from these principles, you will meekly bear with a person who reviles
you, for you will say upon every occasion, “It seemed so to him.”
