When a man speaks evil or does evil to you, remember that he does or says it because he thinks it is fitting for him. It is not possible for him to follow what seems good to you, but only what seems good to him, so that, if his opinion is wrong, he suffers, in that he is the victim of deception. In the same way, if a composite judgement which is true is thought to be false, it is not the judgement that suffers, but the man who is deluded about it. If you act on this principle you will be gentle to him who reviles you, saying to yourself on each occasion, ‘He thought it right.’
