Whether a man is bound to repay a favor at once?

❌ Objection 1 : It seems that a man is bound to repay a favor at once. For we are bound to restore at once what we owe, unless the term be fixed. Now there is no term prescribed for the repayment of favors, and yet this repayment is a duty, as stated above (Article [3]). Therefore a man is bound to repay a favor at once.

❌ Objection 2 : Further, a good action would seem to be all the more praiseworthy according as it is done with greater earnestness. Now earnestness seems to make a man do his duty without any delay. Therefore it is apparently more praiseworthy to repay a favor at once.

❌ Objection 3 : Further, Seneca says (De Benef. ii) that "it is proper to a benefactor to act freely and quickly." Now repayment ought to equal the favor received. Therefore it should be done at once.
