Abstract
Film can be a significant way of doing public philosophy. This chapter sketches some essential public features of philosophy by using popular films. Learning to watch popular films as philosophical expressions, on par with books and articles, brings film and philosophy to inform one another and illuminate important areas of overlap. Memento is an especially uncanny film because it begins with the story's ending. Daniel J. Clark's 2018 documentary film Behind the Curve charts the resurgence of flat‐Earth theory in the United States. Its core thesis is that false, avowed belief in flat‐Earth is sustained partly by an irrational weighing of evidence reinforced by various social, psychological, and economic benefits that come from holding the belief. We gain insight into a classic mechanism of motivated reasoning from Tony Kaye's film American History X, a fictional exploration of the rise of white supremacist ideology in US white working‐class neighborhoods.
