“But,” says our adversary, “he gave you two things, material help and kindly feeling; you, therefore, owe him two.” You might justly say this to one who returns your kindly feeling without troubling himself further; this man is really in your debt; but you cannot say so of one who wishes to repay you, who struggles and leaves no stone unturned to do so; for, as far as in him lies, he repays you in both kinds; in the next place, counting is not always a true test, sometimes one thing is equivalent to two; consequently so intense and ardent a wish to repay takes the place of a material repayment. Indeed, if a feeling of gratitude has no value in repaying a kindness without giving something material, then no one can be grateful to the gods, whom we can repay by gratitude alone. “We cannot,” says our adversary, “give the gods anything else.” Well, but if I am not able to give this man, whose kindness I am bound to return, anything beside my gratitude, why should that which is all that I can bestow on a god be insufficient to prove my gratitude towards a man?
