Turning to the novels, Les Misérables, The Brothers Karamazov, and The Plague, this article focuses on theist–atheist encounters within fiction as guides and challenges to contemporary atheist–theist dialogue. It first provides a discussion of definitions pertinent to our topic and a reflection on the value and limitations of turning to fiction for the study and development of theist–atheist dialogue specifically, and interreligious dialogue more broadly. In examining each of the novels, I will first provide a very brief historical context of when each novel was written, the time and place the covered scenes transpire in the novel, and the authors’ positions toward religion(s) when writing their books. I will close the article on some lessons to glean from these fictional dialogues for contemporary theist–atheist dialogue.
