How then, you will say, can it be true that everything is referred to the chief good, if friendship, and relationship, and all other external things are not contained in the chief good? Why, on this principle,—because we protect those things which are external with those duties which arise from their respective kinds of virtue. For the cultivation of the regard of a friend or a parent, which is the discharge of a duty, is advantageous in the actual fact of its being such, inasmuch as to discharge a duty is a good action; and good actions spring from virtues; and wise men attend to them, using nature as a kind of guide.
But men who are not perfect, though endued with admirable talents and dispositions, are often excited by glory, which has the form and likeness of honourableness. But if they were to be thoroughly acquainted with the nature of that honourableness which is wholly complete and perfect, that one thing which is the most admirable of all things, and the most praiseworthy, with what joy would they be filled, when they are so greatly delighted at its outline and bare idea!For who that is given up to pleasure, and inflamed with the conflagration of desire in the enjoyment of those things which he has most eagerly wished for, can we imagine to be full of such joy as the elder Africanus after he had conquered Hannibal, or the younger one after he had destroyed Carthage? What man was there who was so much elated with the way in which all the people flocked to the Tiber on that day of festivity as Lucius Paullus, when he was leading in triumph king Perses as his prisoner, who was conveyed down on the same river?
Come now, my friend Lucius, build up in your mind the lofty excellence of virtue, and you will not doubt that the men who are possessed of it, and who live with a magnanimous and upright spirit, are always happy; men who are aware that all the movements of fortune, all the changes of affairs and circumstances, must be insignificant and powerless if ever they come to a contest with virtue. For those things which are considered by us as goods of the body, do indeedmake up a happy life, but still not without leaving it possible for a life to be happy without them. For so slight and inconsiderable are those additions of goods, that as stars in the orbit of the sun are not seen, so neither are those qualities, but they are lost in the brilliancy of virtue. And as it is said with truth that the influence of the advantages of the body have but little weight in making life happy, so on the other hand it is too strong an assertion to say that they have no weight at all: for those who argue thus appear to me to forget the principles of nature which they themselves have contended for.
We must, therefore, allow these things some influence: provided only that we understand how much we ought to allow them. It is, however, the part of a philosopher, who seeks not so much for what is specious as for what is true, neither utterly to disregard those things which those very boastful men used to admit to be in accordance with nature; and at the same time to see that the power of virtue, and the authority, if I may say so, of honourableness, is so great that all those other things appear to be, I will not say nothing, but so trivial as to be little better than nothing. This is the language natural to a man who, on the one hand, does not despise everything except virtue, and who, at the same time, honours virtue with the praises which it deserves. This, in short, is a full and perfect explanation of the chief good; and as the others have attempted to detach different portions from the main body of it, each individual among them has wished to appear to have established his own theory as the victorious one.
