You may take the same answer to the question as to whether we ought in all cases to show gratitude for kindness, and whether a benefit ought in all cases to be repaid. It is my duty to show a grateful mind, but in some cases my own poverty, in others the prosperity of the friend to whom I owe some return, will not permit me to give it. What, for instance, am I, a poor man, to give to a king or a rich man in return for his kindness, especially as some men regard it as a wrong to have their benefits repaid, and are wont to pile one benefit upon another? In dealing with such persons, what more can I do than wish to repay them? Yet I ought not to refuse to receive a new benefit, because I have not repaid the former one. I shall take it as freely as it is given, and will offer myself to my friend as a wide field for the exercise of his good nature: he who is unwilling to receive new benefits must be dissatisfied with what he has already received. Do you say, “I shall not be able to return them?” What is that to the purpose? I am willing enough to do so if opportunity or means were given me. He gave it to me, of course, having both opportunity and means: is he a good man or a bad one? if he is a good man, I have a good case against him, and I will not plead if he be a bad one.
