For Aquinas friendship is the ideal type of relationship that rational beings should cultivate. Schwartz argues that Aquinas fundamentally revises some of the main features of Aristotle's paradigmatic account of friendship so as to accommodate the case of friendship between radically unequal beings: man and God. As a result, Aquinas presents a broader view of friendship than Aristotle's, allowing for a higher extent of disagreement. lack of mutual understanding, and inequality between friends.1.
