text: The situation is entirely different in the case of goods whose loss entails some hardship substituted in their place; for example, when good health is impaired there is a change to ill-health; when the eye is put out, we are visited with blindness; we not only lose our speed when our leg-muscles are cut, but infirmity takes the place of speed. But no such danger is involved in the case of the goods to which we referred a moment ago. And why? If I have lost a good friend, I have no false friend whom I must endure in his place; nor if I have buried a dutiful son, must I face in exchange unfilial conduct. In the second place, this does not mean to me the taking-off of a friend or of a child; it is the mere taking-off of their bodies. But a good can be lost in only one way, by changing into what is bad; and this is impossible according to the law of nature, because every virtue, and every work of virtue, abides uncorrupted. Again, even if friends have perished, or children of approved goodness who fulfil their father's prayers for them, there is something that can fill their place. Do you ask what this is? It is that which had made them good in the first place, namely, virtue. Virtue suffers no space in us to be unoccupied; it takes possession of the whole soul and removes all sense of loss. It alone is sufficient; for the strength and beginnings of all goods exist in virtue herself. What does it matter if running water is cut off and flows away, as long as the fountain from which it has flowed is unharmed? You will not maintain that a man's life is more just if his children are unharmed than if they have passed away, nor yet better appointed, nor more intelligent, nor more honourable; therefore, no better, either. The addition of friends does not make one wiser, nor does their taking away make one more foolish; therefore, not happier or more wretched, either. As long as your virtue is unharmed, you will not feel the loss of anything that has been withdrawn from you. You may say: "Come now; is not a man happier when girt about with a large company of friends and children?" Why should this be so? For the Supreme Good is neither impaired nor increased thereby; it abides within its own limits, no matter how Fortune has conducted herself. Whether a long old age falls to one's lot, or whether the end comes on this side of old age – the measure of the Supreme Good is unvaried, in spite of the difference in years.
