But to return again to Scipio, the sole author of the discourse on friendship. He used to complain that there was nothing on which men bestowed so little pains: that every one could tell exactly how many goats or sheep he had, but not how many friends; and while they took pains in procuring the former, they were utterly careless in selecting friends, and possessed no particular marks, so to speak, or tokens by which they might judge of their suitability for friendship. Now the qualities we ought to look out for in making our selection are firmness, stability, constancy. There is a plentiful lack of men so endowed, and it is difficult to form a judgment without testing. Now this testing can only be made during the actual existence of the friendship; for friendship so often precedes the formation of a judgment, and makes a previous test impossible. If we are prudent then, we shall rein in our impulse to affection as we do chariot horses. We make a preliminary trial of horses. So we should of friendship; and should test our friends' characters by a kind of tentative friendship. It may often happen that the untrustworthiness of certain men is completely displayed in a small money matter; others who are proof against a small sum are detected if it be large. But even if some are found who think it mean to prefer money to friendship, where shall we look for those who put friendship before office, civil or military promotions, and political power, and who, when the choice lies between these things on the one side and the claims of friendship on the other, do not give a strong preference to the former? It is not in human nature to be indifferent to political power; and if the price men have to pay for it is the sacrifice of friendship, they think their treason will be thrown into the shade by the magnitude of the reward. This is why true friendship is very difficult to find among those who engage in politics and the contest for office. Where can you find the man to prefer his friend's advancement to his own? And to say nothing of that, think how grievous and almost intolerable it is to most men to share political disaster. You will scarcely find anyone who can bring himself to do that. And though what Ennius says is quite true,--" the hour of need shews the friend indeed,"--yet it is in these two ways that most people betray their untrustworthiness and inconstancy, by looking down on friends when they are themselves prosperous, or deserting them in their distress. A man, then, who has shewn a firm, unshaken, and unvarying friendship in both these contingencies we must reckon as one of a class the rarest in the world, and all but superhuman.
