Aristotle, Nicomachean Ethics book 9 | Friendship When Friends Change | Philosophy Core Concepts

This video focuses on Aristotle's work, the Nicomachean Ethics, and examines his discussion in book 9 of changes in friendships. These changes typically involve either the friends themselves changing, or the circumstances that brought the friends into the relationship - the bases of virtue, pleasure, or usefulness - changing over time.

Aristotle thinks that it is natural for many friendships to break down if the bases for the friendship disappear. At the same time, he doesn't think that one should easily or quickly abandon well-established friendships.
