27. Virtue, I say to you, Caius Fannius, and to you, Quintus Mucius,--virtue both forms and preserves friendships. In it is mutual agreement; in it is stability; in it is consistency of conduct and character. When it has put itself forth and shown its light, and has seen and recognized the same light in another, it draws near to that light, and receives in return what the other has to give; and from this intercourse love, or friendship,--call it which you may,--is kindled. These terms are equally derived in our language from loving; [Footnote: _Amor_..._amicitia_..._ab amando_.] and to love is nothing else than to cherish affection for him whom you love, with no felt need of his service, with no quest of benefit to be obtained from him; while, nevertheless, serviceableness blooms out from friendship, however little you may have had it in view. With this affection I in my youth loved those old men,--Lucius Paulus, Marcus Cato, Caius Gallus, Publius Nasica, Tiberius Gracchus, the father-in-law of my friend Scipio. This relation is more conspicuous among those of the same age, as between myself and Scipio, Lucius Furius, Publius Rupilius, Spurius Mummius. But in my turn, as an old man, I find repose in the attachment of young men, as in yours, and in that of Quintus Tubero, and I am delighted with the intimacy of Publius Rutilius and Aulus Virginius, who are just emerging from boyhood. While the order of human life and of nature is such that another generation must come upon the stage, it would be most desirable, could such a thing be, to reach the goal, so to speak, with those of our own age with whom we started on the race; but since man's life is frail and precarious, we ought always to be in quest of some younger persons whom we may love, and who will love us in return; for when love and kindness cease all enjoyment is taken out of life.
