Let it be understood, by the way, that it is one thing to be grateful for a good office, and another thing to return it—the good will is enough in one case, being as much as the one side demands and the other promises; but the effect is requisite in the other. The physician that has done his best is acquitted though the patient dies, and so is the advocate, though the client may lose his cause. The general of an army, though the battle be lost, is yet worthy of commendation, if he has discharged all the parts of a prudent commander; in this case, the one acquits himself, though the other be never the better for it. He is a grateful man that is always willing and ready: and he that seeks for all means and occasions of requiting a benefit, though without attaining his end, does a great deal more than the man that, without any trouble, makes an immediate return. Suppose my friend a prisoner, and that I have sold my estate for his ransom; I put to sea in foul weather, and upon a coast that is pestered with pirates; my friend happens to be redeemed before I come to the place; my gratitude is as much to be esteemed as if he had been a prisoner; and if I had been taken and robbed myself, it would still have been the same case. Nay, there is a gratitude in the very countenance; for an honest man bears his conscience in his face, and propounds the requital of a good turn in the very moment of receiving it; he is cheerful and confident; and, in the possession of a true friendship, delivered from all anxiety. There is this difference betwixt a thankful man and an unthankful, the one is _always_ pleased in the good he has _done_, and the other only _once_ in what he has _received_. There must be a benignity in the estimation even of the smallest offices; and such a modesty as appears to be obliged in whatsoever it gives. As it is indeed a very great benefit, the opportunity of doing a good office to a worthy man. He that attends to the present, and remembers what is past, shall never be ungrateful. But who shall judge in the case? for a man may be grateful without making a return, and ungrateful with it. Our best way is to help every thing by a fair interpretation; and wheresoever there is a doubt, to allow it the most favorable construction; for he that is exceptious at words, or looks, has a mind to pick a quarrel. For my own part, when I come to cast up my account, and know what I owe, and to whom, though I make my return sooner to some, and later to others, as occasion or fortune will give me leave, yet I will be just to all: I will be grateful to God, to man, to those that have obliged me: nay, even to those that have obliged my friends. I am bound in honor and in conscience to be thankful for what I have received; and if it be not yet full, it is some pleasure still that I may hope for more. For the requital of a favor there must be virtue, occasion, means, and fortune.
