Those persons who are ungrateful and repudiate benefits, not because they do not wish to receive them, but in order that they may not be laid under an obligation for them, are like those who fall into the opposite extreme, and are over grateful, who pray that some trouble or misfortune may befall their benefactors to give them an opportunity of proving how gratefully they remember the benefit which they have received. It is a question whether they are right, and show a truly dutiful feeling; their state of mind is morbid, like that of frantic lovers who long for their mistress to be exiled, that they may accompany her when she leaves her country forsaken by all her friends, or that she may be poor in order that she may the more need what they give her, or who long that she may be ill in order that they may sit by her bedside, and who, in short, out of sheer love form the same wishes as her enemies would wish for her. Thus the results of hatred and of frantic love are very nearly the same; and these lovers are very like those who hope that their friends may meet with difficulties which they may remove, and who thus do a wrong that they may bestow a benefit, whereas it would have been much better for them to do nothing, than by a crime to gain an opportunity of doing good service.
