Far different is the view of those who, like brute beasts, refer everything to sensual pleasure. And no wonder. Men who have degraded all their powers of thought to an object so mean and contemptible can of course raise their eyes to nothing lofty, to nothing grand and divine. Such persons indeed let us leave out of the present question. And let us accept the doctrine that the sensation of love and the warmth of inclination have their origin in a spontaneous feeling which arises directly the presence of probity is indicated. When once men have conceived the inclination, they of course try to attach themselves to the object of it, and move themselves nearer and nearer to him. Their aim is that they may be on the same footing and the same level in regard to affection, and be more inclined to do a good service than to ask a return, and that there should be this noble rivalry between them. Thus both truths will be established. We shall get the most important material advantages from friendship; and its origin from a natural impulse rather than from a sense of need will be at once more dignified and more in accordance with fact. For if it were true that its material advantages cemented friendship, it would be equally true that any change in them would dissolve it. But nature being incapable of change, it follows that genuine friendships are eternal. So much for the origin of friendship. But perhaps you would not care to hear any more. _Fannius_. Nay, pray go on; let us have the rest, Laelius. I take on myself to speak for my friend here as his senior. _Scaevola_. Quite right! Therefore, pray let us hear. 10. _Loelius_. Well, then, my good friends, listen to some conversations about friendship which very frequently passed between Scipio and myself. I must begin by telling you, however, that he used to say that the most difficult thing in the world was for a friendship to remain unimpaired to the end of life. So many things might intervene: conflicting interests; differences of opinion in politics; frequent changes in character, owing sometimes to misfortunes, sometimes to advancing years. He used to illustrate these facts from the analogy of boyhood, since the warmest affections between boys are often laid aside with the boyish toga; and even if they did manage to keep them up to adolescence, they were sometimes broken by a rivalry in courtship, or for some other advantage to which their mutual claims were not compatible. Even if the friendship was prolonged beyond that time, yet it frequently received a rude shock should the two happen to be competitors for office. For while the most fatal blow to friendship in the majority of cases was the lust of gold, in the case of the best men it was a rivalry for office and reputation, by which it had often happened that the most violent enmity had arisen between the closest friends.
