4.9.1
When you see another man in the possession of power (magistracy), set against this the fact that you have not the want (desire) of power; when you see another rich, see what you possess in place of riches: for if you possess nothing in place of them, you are miserable; but if you have not the want of riches, know that you possess more than this man possesses and what is worth much more. Another man possesses a handsome woman (wife): you have the satisfaction of not desiring a handsome wife. Do these things appear to you to be small? And how much would these persons give, these very men who are rich, and in possession of power, and live with handsome women, to be able to despise riches, and power and these very women whom they love and enjoy? Do you not know then what is the thirst of a man who has a fever? He possesses that which is in no degree like the thirst of a man who is in health for the man who is in health ceases to be thirsty after he has drunk; but the sick man being pleased for a short time has a nausea, he converts the drink into bile, vomits, is griped, and more thirsty. It is such a thing to have desire of riches and to possess riches, desire of power and to possess power, desire of a beautiful woman and to sleep with her: to this is added jealousy, fear of being deprived of the thing which you love, indecent words, indecent thoughts, unseemly acts.
