XXXIII. A man bestows a benefit upon me: I receive it just as he wished it to be received: then he gets at once what he wanted, and the only thing which he wanted, and therefore I have proved myself grateful. After this it remains for me to enjoy my own resources, with the addition of an advantage conferred upon me by one whom I have obliged; this advantage is not the remainder of an imperfect service, but an addition to a perfected service. [Footnote: Nothing is wanted to make a benefit, conferred from good motives, perfect: if it is returned, the gratitude is to be counted as net profit.] For example, Phidias makes a statue. Now the product of an art is one thing, and that of a trade is another. It is the business of the art to make the thing which he wished to make, and that of the trade to make it with a profit. Phidias has completed his work, even though he does not sell it. The product, therefore, of his work is threefold: there is the consciousness of having made it, which he receives when his work is completed; there is the fame which he receives; and thirdly, the advantage which he obtains by it, in influence, or by selling it, or otherwise. In like manner the first fruit of a benefit is the consciousness of it, which we feel when we have bestowed it upon the person whom we chose; secondly and thirdly there is the credit which we gain by doing so, and there are those things which we may receive in exchange for it. So when a benefit has been graciously received, the giver has already received gratitude, but has not yet received recompense for it: that which we owe in return is therefore something apart from the benefit itself, for we have paid for the benefit itself when we accept it in a grateful spirit.
