This paper is an enquiry into some commonalities between fiction and atheism. It suggests that ‘disbelief’ may be a state of mind shared by both and asks how a meaningful semantics might be derived from the mental stance of disbelief. Albert Camus’ The Plague, published in 1947 post the trauma of two successive world wars, is a key ‘existentialist’ text that focuses on this dilemma. Not only is this work of fiction especially relevant to our current times of natural, political, (...) economic and psychological distress gone ‘viral’, it is also one in which a blunt question is posed to the atheist hero of the novel, Doctor Rieux, in Oran, a small French Algerian town fighting a terrible pandemic: ‘Do you believe in God, doctor?’. Rieux’s answer is telling: ‘No, but what does that really mean? I’m fumbling in the dark, struggling to make something out.’ It is this human ‘struggle’ to discern the contours of the invisible ‘in the dark’ that could animate the thought worlds of fiction as well as of atheism. The paper seeks to draw out some of these putative similarities through the lens of ‘ordinary language philosophy’ and J.L, Austin and John Searle’s classification of basic speech-acts. It also considers the evolutionary, affective and cross-cultural appeal of the parallel narratives of science and religion. Oran’s most remarkable aspect, Camus insists, is its ‘ordinariness’; yet, it is here that the ‘extraordinariness’ of the plague strikes. Quotidian local circumstances thus paradoxically set in motion the sorts of ‘universal’ inquiries into ‘what it means to be human’ that, my paper argues, alike motivate the fiction of atheism and the atheism of fiction.
