Depression and Dysphoria in the Fiction of David Foster Wallace is the first full-length study of this critically overlooked theme, addressing a major gap in Wallace studies. Wallace has long been recognised as a 'depression laureate' inheriting a mantle previously held by Sylvia Plath due to the frequent and remarkable depictions of depressed characters in his fiction. However, this book resists taking Wallace's fiction at face value and instead situates close reading of his complex fictions in theoretical dialogue both with philosophical and theoretical texts and with contemporary authors and infl uences. This book explores Wallace's complex engagement with philosophical and medical ideas of emotional suffering and demonstrates how this evolves over his career. The shifts in Wallace's thematic focus on various forms of dysphoria, including heartache, loneliness, boredom, and anxiety, as well as depression, correspond to an increasingly pessimistic philosophy underlying his fiction.
