We ought to be even more careful to choose a favorable opportunity when we ask for a benefit to be repaid to us than when we ask for one to be bestowed upon us. We must be temperate in our language, so that the grateful may not take offence, or the ungrateful pretend to do so. If we lived among wise men, it would be our duty to wait in silence until our benefits were returned. Yet even to wise men it would be better to give some hint of what our position required. We ask for help even from the gods themselves, from whose knowledge nothing is hid, although our prayers cannot alter their intentions towards us, but can only recall them to their minds. Homer’s priest, 150 I say, recounts even to the gods his duteous conduct and his pious care of their altars. The second best form of virtue is to be willing and able to take advice. 151
