Yoknapatawpha Railroad: Trains And Mobility In The Novels Of William Faulkner, James Christopher O'Brien Jan 2020

Yoknapatawpha Railroad: Trains And Mobility In The Novels Of William Faulkner, James Christopher O'Brien

Electronic Theses and Dissertations Archive

Though considered one of the foremost of 20th-Century American modernists, many critics accuse William Faulkner of being obsessed with some idyllic southern past. In contrast, my study, utilizing the burgeoning field of mobility studies, focuses on the trains featured within his novels to counter this accusation. As I discuss, Faulkner does indeed question notions of modern progress wrought from industrialization as well as technological advancements, though he never offers blanket condemnations of them. In contrast, his depictions of railroad mobility reveal an attitude of active participation in modernity rather than cantankerous retreat. In my opening chapter, I begin by explaining …
