But I must at the very beginning lay down this principle--_friendship can only exist between good men_. I do not, however, press this too closely, like the philosophers who push their definitions to a superfluous accuracy. They have truth on their side, perhaps, but it is of no practical advantage. Those, I mean, who say that no one but the "wise" is "good." Granted, by all means. But the "wisdom" they mean is one to which no mortal ever yet attained. We must concern ourselves with the facts of everyday life as we find it--not imaginary and ideal perfections. Even Gaius Fannius, Manius Curius, and Tiberius Coruncanius, whom our ancestors decided to be "wise," I could never declare to be so according to their standard. Let them, then, keep this word "wisdom" to themselves. Everybody is irritated by it; no one understands what it means. Let them but grant that the men I mentioned were "good." No, they won't do that either. No one but the "wise" can be allowed that title, say they. Well, then, let us dismiss them and manage as best we may with our own poor mother wit, as the phrase is. We mean then by the "good" _those whose actions and lives leave no question as to their honour, purity, equity, and liberality; who are free from greed, lust, and violence; and who have the courage of their convictions_. The men I have just named may serve as examples. Such men as these being generally accounted "good," let us agree to call them so, on the ground that to the best of human ability they follow nature as the most perfect guide to a good life. Now this truth seems clear to me, that nature has so formed us that a certain tie unites us all, but that this tie becomes stronger from proximity. So it is that fellow-citizens are preferred in our affections to foreigners, relations to strangers; for in their case Nature herself has caused a kind of friendship to exist, though it is one which lacks some of the elements of permanence. Friendship excels relationship in this, that whereas you may eliminate affection from relationship, you cannot do so from friendship. Without it relationship still exists in name, friendship does not. You may best understand this friendship by considering that, whereas the merely natural ties uniting the human race are indefinite, this one is so concentrated, and confined to so narrow a sphere, that affection is ever shared by two persons only or at most by a few.
