Final answer:
Option 4: Perfect friends is not one of the three types of friends as categorized by Aristotle; his classifications are friendships of pleasure, friendships of utility, and friendships of character, with perfect friendships being synonymous with friendships of character.
Step-by-step explanation:
Among the options provided, Option 4: Perfect friends is NOT one of the three types of friends according to Aristotle. Aristotle's three types of friendships are friendships of pleasure, friendships of utility, and friendships of character. The first two are considered incidental and are based on the pleasure or utility that one gets from the other person. These types of friendships tend to dissolve easily and don't necessarily contribute to our virtuous development or eudaimonia. On the other hand, friendships of character are based on mutual appreciation of one another's virtues and contribute significantly to our well-being and flourishing. Aristotle referred to these as perfect friendships, but it is important to note that when he speaks of 'perfect friendships', he is essentially referring to friendships of character.
