On the other hand, suppose one friend to have remained the same while the other has improved, and become greatly the superior in virtue: ought the latter to keep up the friendship? Perhaps it is out of the question; and this becomes especially clear when the gap between them is a wide one, as may happen with two people who were friends in boyhood. One may have remained a boy in mind, while the other is a man of the highest ability; how can they be friends, when they have different tastes and different likes and dislikes? They will no longer even enjoy each other's society; but without this, intercourse and therefore friendship are, as we saw,1 impossible. But this has been discussed already.
