Book 6.39
Yet we must not condemn every thing which we find worthy of blame, as, for instance, this wish about our friends which we have been discussing, arises from a misdirected feeling of affection, and falls into the very error which it strives to avoid, for the man is ungrateful at the very time when he hurries to prove his gratitude. He prays aloud, "May he fall into my power, may he need my influence, may not be able to be safe and respectable without my aid, may he be so unfortunate that whatever return I make to him may be regarded as a benefit." To the gods alone he adds, "May domestic treasons encompass him, which can be quelled by me alone; may some powerful and virulent enemy, some excited and armed mob, assail him; may he be set upon by a creditor or an informer."
