“The final form of friendship that Aristotle outlined is also the most preferable out of the three.
Rather than utility or pleasure, this kind of relationship is based on a mutual appreciation of the virtues that the other party holds dear. It’s the people themselves and the qualities that they represent that provides the incentive for the two parties to be in each other’s lives.
Rather than being short-lived, such a relationship often lasts until the end, and there is quite generally a base level of goodness required in each person for it to exist in the first place.
For most things, life is long enough. It is, however, too short for the wrong kinds of friendship.”
