Film is an excellent medium for displaying and wrestling with practical philosophy, which includes ethics, political theory, and philosophy of religion (as well as aesthetics, which is a rather obvious topic for film). A film that has a character personifying a particular philosopher’s thought and antagonists rejecting that philosophy, and goes so far as to have a character read on-screen from a philosopher’s book, is the epitome of film doing philosophy. The film, All That Heaven Allows (1955), is such a film.
