As Aristotle also observed, friendships help to satisfy the neediness we have in common as finite creatures and social animals. If we were gods and entirely self-sufficient, we might be able to do without friends. But we are not gods and so we need friends in order to flourish and be happy. Ironically, this neediness, which is sometimes mistakenly thought of as weakness, is the soil in which the mutuality and reciprocity of friendship grow.
