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.
