The friendship of which pleasure is the motive bears some resemblance to the foregoing; for good men, too, are pleasant to each other. So also does that of which the useful is the motive; for good men are useful also to one another. And in these cases, too, the friendship is most likely to endure when that which each gets from the other is the same ( e.g. pleasure), and not only the same, but arising from the same source⁠—a friendship between two wits, for instance, rather than one between a lover and his beloved. For the source of pleasure in the latter case is not the same for both: the lover delights to look upon his beloved, the beloved likes to have attentions paid him; but when the bloom of youth is gone, the friendship sometimes vanishes also; for the one misses the beauty that used to please him, the other misses the attentions. But, on the other hand, they frequently continue friends, i.e. when their intercourse has brought them to care for each other’s characters, and they are similar in character.
