Responding to long-term debate over the position and outlook of the love story in Hemingway’s A Farewell to Arms (1929), this essay argues that love is the centering principle of the novel. Indeed, the narrative posits a world in which love magnetically attracts the characters with its power to illuminate lived experience with a tangible sense of meaning. Deploying actor-network theory and recognizing the retrospective, mediated nature of Frederic Henry’s narrative, this essay analyzes the novel for what it tells today’s readers about one man’s attempt to find meaning after the horrors of the Great War.
