98.1-2
1. You need never believe that anyone who depends upon happiness is happy! It is a fragile support—this delight in adventitious things; the joy which entered from without will some day depart. But that joy which springs wholly from oneself is leal and sound; it increases and attends us to the last; while all other things which provoke the admiration of the crowd are but temporary Goods. You may reply: “What do you mean? Cannot such things serve both for utility and for delight?” Of course. But only if they depend on us, and not we on them. 2. All things that Fortune looks upon become productive and pleasant, only if he who possesses them is in possession also of himself, and is not in the power of that which belongs to him. For men make a mistake, my dear Lucilius, if they hold that anything good, or evil either, is bestowed upon us by Fortune; it is simply the raw material of Goods and Ills that she gives to us—the sources of things which, in our keeping, will develop into good or ill. For the soul is more powerful than any sort of Fortune; by its own agency it guides its affairs in either direction, and of its own power it can produce a happy life, or a wretched one.
