In friendships based on virtue, on the other hand, such accusations do not occur, but it would seem that the measure of the service is the purpose of him who does it; for virtue and moral character are determined by purpose.
Quarrels occur also in unequal friendships; for sometimes each claims the larger share, but when this happens the friendship is dissolved. For instance, the better of the two thinks he ought to have the larger share; “the good man’s share is larger,” he says: the more useful of the two makes the same claim; “it is allowed,” he says, “that a useless person should not share equally; for friendship degenerates into gratuitous service unless that which each receives from the friendship be proportionate to the value of what he does.” For such people fancy that the same rule should hold in friendship as in a commercial partnership, where those who put in more take a larger share.
