Do not take pride in any excellence that is not your own. If a horse could be proud, it might say, "I am handsome," and such a statement might be acceptable. But when you proudly say, "I have a handsome horse," you should understand that you are taking pride in a horse's good. What has the horse's good to do with you? What is yours? Only your reaction to things. When you behave in accordance with nature, you will take pride only in some good that is your own.
