XXVIII. Consider within yourself, whether you have always shown gratitude to those to whom you owe it, whether no one's kindness has ever been wasted upon you, whether you constantly bear in mind all the benefits which you have received. You will find that those which you received as a boy were forgotten before you became a man; that those bestowed upon you as a young man slipped from your memory when you became an old one. Some we have lost, some we have thrown away, some have by degrees passed out of our sight, to some we have wilfully shut our eyes. If I am to make excuses for your weakness, I must say in the first place that human memory is a frail vessel, and is not large enough to contain the mass of things placed in it; the more it receives, the more it must necessarily lose; the oldest things in it give way to the newest. Thus it comes to pass that your nurse has hardly any influence with you, because the lapse of time has set the kindness which you received from her at so great a distance; thus it is that you no longer look upon your teacher with respect; and that now when you are busy about your candidature for the consulate or the priesthood, you forget those who supported you in your election to the quaestorship. If you carefully examine yourself, perhaps you will find the vice of which you complain in your own bosom; you are wrong in being angry with a universal failing, and foolish also, for it is your own as well; you must pardon others, that you may yourself be acquitted. You will make your friend a better man by bearing with him, you will in all cases make him a worse one by reproaching him. You can have no reason for rendering him shameless; let him preserve any remnants of modesty which he may have. Too loud reproaches have often dispelled a modesty which might have borne good fruit. No man fears to be that which all men see that he is; when his fault is made public, he loses his sense of shame. XXIX. You say, "I have lost the benefit which I bestowed." Yet do we say that we have lost what we consecrate to heaven, and a benefit well bestowed, even though we get an ill return for it, is to be reckoned among things consecrated. Our friend is not such a man as we hoped he was; still, let us, unlike him, remain the same as we were. The loss did not take place when he proved himself so; his ingratitude cannot be made public without reflecting some shame upon us, since to complain of the loss of a benefit is a sign that it was not well bestowed. As far as we are able we ought to plead with ourselves on his behalf: "Perhaps he was not able to return it, perhaps he did not know of it, perhaps he will still do so." A wise and forbearing creditor prevents the loss of some debts by encouraging his debtor and giving him time. We ought to do the same, we ought to deal tenderly with a weakly sense of honour.
