Some things make us angry because we heard them from others. Other things make us angry because we saw or heard them ourselves. We should be slow to believe what people tell us. Many people lie to deceive us. Many others lie because they've been deceived themselves. Some people make false accusations to win our favor. They invent wrongs so they can pretend to be angry on our behalf. One person lies out of spite, hoping to turn trusting friends against each other. Others lie because they're suspicious and want entertainment. They like to watch from a safe distance as people they've set against each other fight.
We are made angry by some things which we learn at second-hand, and by some which we ourselves hear or see. Now, we ought to be slow to believe what is told us. Many tell lies in order to deceive us, and many because they are themselves deceived. Some seek to win our favour by false accusations, and invent wrongs in order that they may appear angry at our having suffered them. One man lies out of spite, that he may set trusting friends at variance; some because they are suspicious,[12] and wish to see sport, and watch from a safe distance those whom they have set by the ears.
