But, to return to Scipio, who was all the time talking about friendship, he often complained that men exercised greater care about all other matters; that one could always tell how many goats and sheep he had, but could not tell how many friends he had; and that men were careful in selecting their beasts, but were negligent in the choice of friends, and had nothing like marks and tokens [Footnote: Latin, _signa et notas,_ the marks and tokens by which the quality and worth of goats and sheep were estimated.] by which to determine the fitness of friends. Firm, steadfast, self-consistent men are to be chosen as friends, and of this kind of men there is a great dearth. It is very difficult to judge of character before we have tested it; but we can test it only after firendship is begun. Thus friendship is prone to outrun judgment, and to render a fair trial impossible. It is therefore the part of a wise man to arrest the impulse of kindly feeling, as we check a carriage in its course, that, as we use only horses that have been tried, so we may avail ourselves of friendships in which the characters of our friends have been somehow put to the test. Some readily show how fickle their friendship is in paltry pecuniary matters; others, whom a slight consideration of that kind cannot influence, betray themselves when a large amount is involved. But if some can be found who think it mean to prefer money to friendship, where shall we come upon those who do not put honors, civic offices, military commands, places of power and trust, before friendship, so that when these are offered on the one hand, and the claims of friendship on the other, they will much rather make choice of the objects of ambition? For nature is too feeble to despise a commanding station, and even though it be obtained by the violation of friendship men think that this fault will be thrown into obscurity, because it was not without a weighty motive that they held friendship in abeyance. Thus true friendships are rare among those who are in public office, and concerned in the affairs of the State. For where will you find him who prefers a friend's promotion to his own? What more shall I say? Not to dwell longer on the influence of ambition upon friendship, how burdensome how difficult does it seem to most men to share misfortunes to which it is not easy to find those who are willing to stoop. Although Ennius is right in saying "In unsure fortune a sure friend is seen," yet one of these two things convicts most persons of fickleness and weakness,--either their despising their friends when they themselves are prosperous, or deserting their friends in adversity. 18 Him, then, who alike in either event shall have shown himself unwavering, constant, firm in friendship we ought to regard as of an exceedingly rare and almost divine order of men.
