Book 9

Section 1

In all dissimilar friendships, it is proportion, as has been said, that establishes equality and preserves the friendship; just as, in the relations between fellow-citizens, the shoemaker receives payment for his shoes, and the weaver and the other craftsmen for their products, according to value rendered.

In these business relationships then a common measure has been devised, namely money, and this is a standard to which all things are referred and by which they are measured. But in sentimental friendships, the lover sometimes complains that his warmest affection meets with no affection in return, it may be because there is nothing in him to arouse affection; while the person loved frequently complains that the lover who formerly promised everything now fulfils none of his promises.

Such disputes occur when pleasure is the motive of the friendship on the lover’s side and profit on the side of the beloved, and when they no longer each possess the desired attribute. For in a friendship based on these motives, a rupture occurs as soon as the parties cease to obtain the things for the sake of which they were friends; seeing that neither loved the other in himself, but some attribute he possessed that was not permanent; so that these friendships are not permanent either. But friendship based on character is disinterested, and therefore lasting, as has been said.

Differences arise when the friends do not obtain what they desire, but something else; for not to get what you want is almost the same as not to get anything at all. For instance, there is the story of the man who hired a harper, and promised that the better he played the more he would pay him; but next morning, when the harper asked him to fulfil his promise, he said that he had already paid for the pleasure he had received by the pleasure he had given. This would have been all right if both had wanted pleasure; but when one wants amusement and the other gain, and one gets what he wants and the other does not, it would not be a fair bargain; for it is the thing that a man happens to need that he sets his heart on, and only to get that is he ready to give what he does.

Which party’s business is it to decide the amount of the return due? Should it be assessed by the one who proffers the initial service? Or rather by the one who receives it, since the other by proffering it seems to leave the matter to him? This we are told was the practice of Protagoras ; when he gave lessons in any subject, he used to tell his pupil to estimate the value he set upon his knowledge, and accepted a fee of that amount.

In such matters however some people prefer the principle of the wage stated. But people who take the money in advance, and then, having made extravagant professions, fail to perform what they undertook, naturally meet with complaints because they have not fulfilled their bargain.

Perhaps however the sophists are bound to demand their fees in advance, since nobody would pay money for the knowledge which they possess. Persons paid in advance then naturally meet with complaints if they do not perform the service for which they have taken the pay.

But in cases where no agreement is come to as to the value of the service, if it is proffered for the recipient’s own sake, as has been said above, no complaint arises, for a friendship based on virtue does not give rise to quarrels; and the return made should be in proportion to the intention of the benefactor, since intention is the measure of a friend, and of virtue. This is the principle on which it would seem that payment ought to be made to those who have imparted instruction in philosophy; for the value of their service is not measurable in money, and no honor paid them could be an equivalent, but no doubt all that can be expected is that to them, as to the gods and to our parents, we should make such return as is in our Power.

When on the other hand the gift is not disinterested but made with a view to a recompense, it is no doubt the best thing that a return should be made such as both parties concur in thinking to be what is due. But failing such concurrence, it would seem to be not only inevitable but just that the amount of the return should be fixed by the party that received the initial service, since the donor will have recovered what the recipient really owes when he has been paid the value of the service to him, or the sum that he would have been willing to pay as the price of the pleasure.

For in buying and selling also this seems to be the practice ; and in some countries the law does not allow actions for the enforcement of voluntary covenants, on the ground that when you have trusted a man you ought to conclude the transaction as you began it. For it is thought fairer for the price to be fixed by the person who received credit than by the one who gave credit. For as a rule those who have a thing value it differently from those who want to get it. For one’s own possessions and gifts always seem to one worth a great deal; but nevertheless the repayment is actually determined by the valuation of the recipient. But he ought no doubt to estimate the gift not at what it seems to him to be worth now that he has received it, but at the value he put on it before he received it.
