Final answer:
Aristotle discusses incidental friendships and perfect friendships as something that has dissolved many a friendship. Incidental friendships are based on utility or pleasure, while perfect friendships are based on the goodness of the characters and foster virtuous development. Aristotle believes that friendships based on an appreciation of someone's character are stronger and do not dissolve easily.
Step-by-step explanation:
Aristotle discusses incidental friendships and perfect friendships as something that has dissolved many a friendship in his work Nicomachean Ethics. Incidental friendships are based on utility or pleasure, where each person participates only because they get something from it. These friendships do not contribute to our happiness or foster virtuous development. On the other hand, perfect friendships are based on the goodness of the characters of the individuals involved and foster virtuous development. They make it possible to contemplate virtuous actions while still thinking of them as one's own. Aristotle believes that friendships based on an appreciation of someone's character are stronger and do not dissolve easily when circumstances change.
