Aristotle's Friendship Of Utility

2. The friendship of utility Aristotle’s second type of friendship is the friendship of utility. In a friendship of utility, “people love one another because they are useful and only in so far as they are useful” (116). A damaged friendship of utility can be repaired with monetary compensation for the damage that was done – since all utility eventually amounts to money anyway. A friendship of utility will naturally end when one or both members stop being useful to the other. Aristotle says that utility constitutes the majority of friendships. Most of the dozens or hundreds of relationships that most people have at any given moment are initiated and maintained because at least one person (usually both) gains something from the relationship.
This kind of relationship is not just limited to humans, either; they also occur between humans and domesticated animals, and between all sorts of organisms in nature.
3. The friendship of pleasure
Aristotle’s third type of friendship is the friendship of pleasure. The foundation for this kind of friendship is not love for the other person, nor utility, but simple pleasure or fun. If a friendship of pleasure is damaged, it is generally not fixed, but replaced. This is because the foundational pleasure of the friendship is ultimately replaceable, unlike love or, to a lesser degree, utility. A friendship of pleasure will naturally end when at least one person stops being pleasurable for the other person. Aristotle notes that this kind of friendship is “characteristic of the young, who are sensitive to what is pleasant” (116). I think this is just Aristotle’s way of saying that young people like to party, relax, and overall just want to have fun.
