This essay explores the existential philosophy that exists in Chuck Palahniuck’s first novel, Fight Club (1996). Surprisingly, there has been little discussion of this novel’s connection to Jean-Paul Sartre’s notion of the look and the three patterns of bad faith in Being and Nothingness nor of Camus’s discussion of calculated culpability in The Just Assassins; this has largely been overlooked and presents a creative opportunity to better interpret Fight Club, its concomitant existential analysis, and the continuing fight between Camus and Sartre’s political stances, not to mention the interpretive territory of existentialist humor.
